All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
An embodiment of the present invention provides an apparatus for producing a gypsum light hollow partition wall panel, as shown in fig. 1 to 8, which includes a stirring device 10, a gas separation device 20, and a molding mainframe 30.
Wherein, the stirring device 10 is provided with a first feeding channel 111, a first discharging channel 112 and a first water inlet channel 113, the production raw materials and the water enter the stirring device 10 from the first feeding channel 111 and the first water inlet channel 113 respectively, and are mixed and stirred in the stirring device 10 to generate injection molding raw pulp, the injection molding raw pulp enters the gas separation device 20 through the first discharging channel 112, and the stirring device 10 can simultaneously self-clean the inner wall of the stirring device 10 in the stirring process; the gas separation device 20 is provided with a second feeding channel 211, a second discharging channel 212, a second water inlet channel 213 and a water outlet channel 214, the second feeding channel 211 is communicated with the first discharging channel 112, injection molding raw pulp enters the gas separation device 20 from the second feeding channel 211, the water outlet channel 214 is communicated with the first water inlet channel 113, water enters the gas separation device 20 from the second water inlet channel 213 and enters the stirring device 10 through the water outlet channel 214 and the first water inlet channel 113, the injection molding raw pulp is subjected to gas separation in the gas separation device 20 to produce production raw pulp, and the production raw pulp enters the molding host 30 from the second discharging channel 212; the forming host 30 is provided with a material injection channel, the material injection channel is communicated with the second discharging channel 212, and the production raw pulp enters the forming host 30 through the material injection channel and is formed in the forming host 30. It will be appreciated by those skilled in the art that in this embodiment, a base 50 is further provided, and the stirring device 10, the gas separation device 20 and the forming main unit 30 are all fixed to the base 50, and the purpose of the base 50 is to ensure the consistency of the installation of the stirring device 10, the gas separation device 20 and the forming main unit 30.
In this embodiment, the raw material and water are fed into the stirring apparatus 10 from the first feed passage 111 and the first water feed passage 113, respectively, and chemical reaction occurs in the stirring apparatus 10 to convert the raw material into injection molding raw slurry, and the raw material and water can be sufficiently mixed by stirring by the stirring apparatus 10. Simultaneously in the stirring process of the stirring device 10, the inner wall of the stirring device 10 can be automatically cleaned, injection molding raw pulp is prevented from being adhered to the inner wall of the stirring device 10 due to long-time operation, solidification is further caused, and the phenomenon that the stirring device 10 is blocked is avoided, so that the situation that the injection molding raw pulp adhered to the inner wall of the stirring device 10 needs to be cleaned after a period of continuous operation in the prior art is avoided, and the production efficiency is improved. In this embodiment, after being stirred by the stirring device 10, the generated injection molding raw slurry flows out of the stirring device 10 through the first discharge passage 112, and enters the gas separation device 20 through the second feed passage 211 communicating with the first discharge passage 112. After the injection molding raw pulp enters the gas separation device 20, the gas contained in the injection molding raw pulp is separated under the action of the gas separation device 20, so as to form the production raw pulp required by final production. The raw production slurry enters the forming host 30 through the material injection channel communicated with the second material outlet channel 212, and finally the required gypsum light hollow partition board is produced in the forming host 30. Because the gas in the production raw slurry is separated before the production raw slurry enters the forming main machine 30, the gypsum light hollow partition board produced finally does not contain bubbles, thereby ensuring the surface smoothness and the overall strength of the gypsum light hollow partition board formed finally.
Further, the stirring device 10 includes a stirring vessel 11, and a high-speed rotation shaft 12, a feeding mechanism 13, and a stirring paddle 14 provided inside the stirring vessel 11. Wherein, the stirring barrel 11 is provided with a first mounting hole, a first feeding channel 111, a first discharging channel 112 and a first water inlet channel 113; a high-speed rotation shaft 12 passing through the first mounting hole and extending toward the inside of the stirring tub 11; the feeding mechanism 13 comprises a differential mechanism 131 and a feeding screw rod 132, the feeding screw rod 132 rotates along with the high-speed rotating shaft 12 through the differential mechanism 131, and the rotating speed of the feeding screw rod 132 is smaller than that of the high-speed rotating shaft 12; the stirring paddle 14 is vertically and fixedly connected with the lower end of the high-speed rotating shaft 12, and the rotating diameter of one end of the stirring paddle 14 away from the high-speed rotating shaft 12 is matched with the diameter of the bottom inner cavity of the stirring barrel 11. It will be appreciated by those skilled in the art that the feeding screw 132 may rotate in the same direction or in the opposite direction along with the high-speed rotation shaft 12 through the differential 131, and in this embodiment, the same direction rotation is preferred, and the same direction rotation is simple in structure, and the speed change can be achieved by using a smaller volume, so that the volume of this embodiment is optimal. It will be further understood by those skilled in the art that the first discharge channel 112 may be one or more, and the specific number may be set according to the requirement of the subsequent process, and in this embodiment, it is preferably one discharge channel.
In this embodiment, the raw material and the water are introduced into the stirring vessel 11 from the first feed passage 111 and the first water feed passage 113, respectively, and stirred in the stirring vessel 11 to form injection molding raw slurry, and then introduced into the gas separation device 20 from the first discharge passage 112 by the stirring paddle 14. Because the rotation speed of the feed screw 132 is smaller than the rotation speed of the stirring paddle 14, a coaxial asynchronous differential shearing motion is formed between the stirring paddle 14 and the feed screw 132, so that raw materials between the tail end of the feed screw 132 and the stirring paddle 14 can be rapidly taken away, a blocking phenomenon caused by raw material accumulation between the feed screw 132 and the stirring paddle 14 is prevented, and finally the rotating shaft 221 is damaged. Meanwhile, in the embodiment, the rotating diameter of one end of the stirring paddle 14, which is close to the inner wall of the stirring barrel 11, is adapted to the inner diameter of the stirring barrel 11, and the purpose of the arrangement is to enable the stirring paddle 14 to take away injection molding primary pulp, which is close to the inner wall of the stirring barrel 11, in the rotating process, so that the injection molding primary pulp is prevented from solidifying on the inner wall of the stirring barrel 11, the purpose of cleaning the inner wall of the stirring barrel 11 is achieved, and compared with the prior art, the stirring barrel 11 is not required to be continuously operated for a period of time to stop and clean the stirring barrel 11, thereby saving manpower and material resources and improving the production efficiency.
Further, a differential cavity 114, a feeding cavity 115 and a stirring cavity 116 which are coaxial are sequentially arranged in the stirring barrel 11 from top to bottom, a differential mechanism 131 is positioned in the differential cavity 114, a feeding screw rod 132 is positioned in the feeding cavity 115, a stirring paddle 14 is positioned in the stirring cavity 116, and the rotating diameter of one end of the stirring paddle 14 far away from the high-speed rotating shaft 12 is matched with the diameter of the stirring cavity 116; the first feed passage 111 extends from the outer side wall of the feed chamber 115 into the feed chamber 115, the first discharge passage 112 extends from the inner side wall of the bottom of the stirring chamber 116 to the outer side wall of the bottom of the stirring chamber 116, and the first water inlet passage 113 extends from the outer side wall of the upper end of the stirring chamber 116 into the stirring chamber 116. In this embodiment, the raw materials and water are mixed in the stirring chamber 116, and under the high-speed rotation of the stirring paddle 14, the injection molding raw slurry in the stirring chamber 116 forms high pressure, and finally flows into the gas separation device 20 in a short time through the first discharging channel 112 arranged at the bottom of the stirring chamber 116. It will be appreciated by those skilled in the art that the inlet end of the first feed channel 111 may be provided with various communication means with the outside, for example, may be communicated by means of flange connection or throat connection, and may be specifically determined according to the previous procedure or feeding mode.
In this embodiment, in order to further ensure that the material does not form a blockage between the feed screw 132 and the stirring screw 14, the diameter of the feed chamber 115 is smaller than the diameter of the stirring chamber 116, so that the material between the stirring screw 14 and the feed screw 132 can be quickly carried away by the differential shearing motion between the stirring screw 14 and the feed screw 132. Meanwhile, in the embodiment, since the diameter of the feeding cavity 115 is smaller than that of the stirring cavity 116, when the outlet of the first water inlet channel 113 is arranged, the outlet of the first water inlet channel 113 should be close to the central position of the stirring cavity 116, so that the purpose of the arrangement is to further wash the raw materials between the stirring paddle 14 and the feeding screw 132, so that no residue of the raw materials exists between the stirring paddle 14 and the feeding screw 132, and meanwhile, the arrangement can prolong the mixing reaction time of the raw materials and water, and make the chemical reaction between the raw materials more complete.
In this embodiment, the height of the stirring chamber 116 is also set to be adapted to the thickness of the stirring paddle 14. It will be appreciated by those skilled in the art that if the height of the stirring chamber 116 is much greater than the thickness of the stirring paddle 14, the high speed rotation of the stirring paddle 14 in the stirring chamber 116 makes it difficult to form a high pressure on the injection molding syrup, so that the injection molding syrup cannot be rapidly flowed from the first discharging channel 112 into the gas separation device 20, and the injection molding syrup formed by mixing the raw materials with water is solidified in a relatively short time, eventually resulting in clogging of the stirring chamber 116. Therefore, the height of the stirring cavity 116 should be adapted to the thickness of the stirring paddle 14, and the specific matching relationship between the stirring cavity 116 and the stirring paddle 14 can be determined according to the ratio of the raw materials, when the raw materials react faster when meeting water, the gap between the stirring cavity 116 and the stirring paddle 14 should be properly smaller, otherwise, the gap between the stirring cavity and the stirring paddle can be properly larger.
Further, the stirring paddle 14 is composed of a connecting piece and a plurality of blades, the connecting piece is fixedly sleeved at the lower end of the high-speed rotating shaft 12, the blades are uniformly distributed along the circumferential direction of the connecting piece, the blades are in a hook shape, and the rotation of the stirring paddle 14 is consistent with the bending direction of the blades. It will be appreciated by those skilled in the art that the plurality of blades may be fixedly connected to the connector by welding or may be integrally formed, and in this embodiment, the blades are preferably integrally formed, so that the strength of the stirring paddle 14 may be increased. It will be further understood by those skilled in the art that the number of the blades may be three, four or five, and in this embodiment, two are preferred, and the number of the specific arrangements may be set according to needs, for example, when the number of the first discharging passages 112 is increased, the pressure provided by the stirring paddles 14 may be increased, and at this time, the number of the blades in the stirring paddles 14 may be appropriately increased to ensure the pressure in each discharging passage. In this embodiment, when the injection molding raw slurry in the stirring cavity 116 rotates in the stirring cavity 116 along with the stirring paddle 14, the injection molding raw slurry gathers towards the inner wall of the stirring cavity 116 under the action of centrifugal force, and as the stirring paddle 14 rotates, more and more raw materials attached to the inner wall of the stirring cavity 116 will adhere, and finally the injection molding raw slurry on the inner wall of the stirring cavity 116 is not easy to be removed and solidified. In order to prevent this phenomenon, the rotating diameter of the end of the stirring paddle 14 close to the inner wall of the stirring cavity 116 is set to be adapted to the diameter of the stirring cavity 116, and the purpose of setting the blades to be bent in the shape of a hook and enabling the bending direction to be consistent with the rotating direction is to drive the injection molding raw pulp close to the inner wall of the stirring cavity 116 to the rotating circle center in the rotating process of the stirring paddle 14, so that the phenomenon that the injection molding raw pulp of the inner wall of the stirring cavity 116 is more and more under the action of centrifugal force, and finally the end of the blades far away from the connecting piece is broken due to the increase of resistance is avoided. Simultaneously, the solidification phenomenon caused by excessive accumulation of injection molding raw pulp on the inner wall of the stirring cavity 116 is avoided, and the self-cleaning capacity of the stirring cavity 116 is further enhanced.

In the present embodiment, the water outlet channel 214 is communicated with the first water inlet channel 113 through a hose (not shown in the figure); the water injection means is a reservoir (not shown) which is in communication with the second water inlet channel 213 via a water pump.
In this embodiment, the injection molding raw slurry enters the disperser 223 from the second feeding channel 211, and the disperser 223 rotates at a high speed under the drive of the rotating shaft 221, so that the injection molding raw slurry entering the disperser 223 is dispersed, and the gas contained in the injection molding raw slurry is separated from the injection molding raw slurry. Meanwhile, the upper and lower sides of the disperser 223 are provided with the exhaust paddles 222 and the pressure paddles 224, and when the two paddles rotate, air flowing to the exhaust paddles 222 is formed, air separated from the injection molding raw pulp flows to one side of the exhaust paddles 222 along with the air flowing between the exhaust paddles 222 and the pressure paddles 224 and finally is discharged through the water outlet channel 214, and the residual raw pulp which does not contain air enters the stirring paddles 14 under the action of self gravity and finally enters the molding host 30 through the second discharging channel 212 under the high pressure formed by high-speed rotation of the pressure paddles 224. Therefore, the gas in the injection molding raw slurry processed by the gas separation device 20 is removed to form the final molded gas-free production raw slurry, thereby ensuring the smooth surface and uniform density of the final molded product.
Further, an exhaust cavity 215, a dispersion cavity 216 and a pressure cavity 217 are coaxially arranged in the shell 21 from top to bottom in sequence, the diameter of the dispersion cavity 216 is smaller than that of the exhaust cavity 215 and the pressure cavity 217, an exhaust paddle 222 is positioned in the exhaust cavity 215, the dispersion paddle is positioned in the dispersion cavity 216, and the pressure paddle 224 is positioned in the pressure cavity 217; the second feed channel 211 extends from the outer side wall of the dispersion chamber 216 into the dispersion chamber 216, the second discharge channel 212 extends from the inner side wall of the bottom of the pressure chamber 217 to the outer side wall of the bottom of the pressure chamber 217, the second feed channel 213 extends from the outer side wall of the dispersion chamber 216 into the discharge chamber 215, and the discharge channel 214 extends from the inner side wall of the discharge chamber 215 to the outer side wall of the discharge chamber 215.

It will be appreciated by those skilled in the art that if the diameter of the dispersing cavity 216 is larger than that of the air discharging cavity 215 and the pressure cavity 217, at the position where the dispersing cavity 216 is larger than that of the air discharging cavity 215 and the pressure cavity 217, the air discharged by scattering the injection molding raw slurry possibly enters the pressure cavity 217 along with the injection molding raw slurry, and finally enters the forming main machine 30 under the action of the stirring paddle 14, so that the final gypsum lightweight hollow partition board is reduced in surface smoothness and uneven in density due to the inclusion of air bubbles, and therefore, in the embodiment, the diameter of the dispersing cavity 216 is smaller than that of the pressure cavity 217 and the air discharging cavity 215 is provided for enabling the air discharging to be more thorough, and ensuring that the final gypsum lightweight hollow partition board is better in quality.
Further, the exhaust paddle 222 and the pressure paddle 224 each include a connecting member and a plurality of blades, the connecting member is fixedly sleeved on the rotating shaft 221, the blades are fixedly connected to the connecting member, the blades are uniformly distributed along the circumferential direction of the connecting member, and the number of the blades of the exhaust paddle 222 is greater than that of the blades of the pressure paddle 224. It will be appreciated by those skilled in the art that the blade and the connector may be integrally formed by welding, and in this embodiment are preferably integrally formed. In this embodiment, the pressure paddle 224 and the exhaust paddle 222 rotate coaxially, so that the pressure paddle 224 and the exhaust paddle 222 simultaneously draw gas therebetween, and the number of blades in the exhaust paddle 222 is greater than the number of blades in the pressure paddle 224, so that the capacity of the exhaust paddle 222 to draw gas is greater than the capacity of the pressure paddle 224 to draw gas, and as a result, a gas flow from the pressure paddle 224 to the exhaust paddle 222 is formed between the exhaust paddle 222 and the stirring paddle 14, and finally the broken gas in the injection molding raw slurry flows to the exhaust paddle 222 side along with the gas flow from the pressure paddle 224 to the exhaust paddle 222 formed between the exhaust paddle 222 and the pressure paddle 224. It will be appreciated by those skilled in the art that the difference in the number of blades in the discharge paddle 222 and the pressure paddle 224 may be set according to specific needs, and when the flow rate of the injection molding raw slurry in the second feed channel 211 is large, the difference in the number of blades in the pressure paddle 224 and the discharge paddle 222 may be appropriately increased, and conversely, the difference in the number between the two may be appropriately decreased. It will be further appreciated by those skilled in the art that the number of blades in the pressure paddle 224 may be set according to the production requirements, and the number of blades in the pressure paddle 224 may be increased appropriately when the second discharge passage 212 is provided with a larger number or the volume of product is larger, which requires an increased flow of the product slurry in the second discharge passage 212.

In this embodiment, the blades of the pressure paddle 224 and the exhaust paddle 222 are both in a hook shape, and the rotation directions of the exhaust paddle 222 and the pressure stirring paddle 14 are both identical to the bending directions of the blades.

Therefore, the purpose of setting the blades of the pressure paddle 224 and the exhaust paddle 222 to be hooked and make the bending direction consistent with the rotation direction is to make the blades of the pressure paddle 224 and the exhaust paddle 222 be hooked to drive the production raw pulp on the inner walls close to the pressure chamber 217 and the exhaust chamber 215 to the rotation center in the rotation process, so that the phenomenon that the more the production raw pulp on the inner walls of the pressure chamber 217 and the exhaust chamber 215 is gathered under the action of centrifugal force, the more the fracture phenomenon is caused at the end of the blades far away from the connecting piece due to the increase of resistance. At the same time, the solidification phenomenon caused by excessive raw material accumulation on the inner walls of the pressure cavity 217 and the exhaust cavity 215 is avoided, and the pressure cavity 217 and the exhaust cavity 215 have self-cleaning capability.
In this embodiment, in order to improve the automatic cleaning capability of the gas separation device 20, the rotation diameter of the end of the blade of the exhaust paddle 222 near the side wall of the exhaust chamber 215 is adapted to the diameter of the exhaust chamber 215, and the rotation diameter of the end of the blade of the pressure paddle 224 near the pressure chamber 217 is adapted to the diameter of the pressure chamber 217. The purpose of this arrangement is to allow the blades to further carry away the material on the inner walls of the pressure chamber 217 and the exhaust chamber 215 during rotation of the pressure paddle 224 and the exhaust paddle 222, so that the self-cleaning capacity of the pressure chamber 217 and the exhaust chamber 215 is stronger.

Further, the molding host 30 comprises an injection mold 31, an upper mold 32, a lower mold 33, a first side mold 34, a second side mold 35 and a plurality of groups of drawing mandrels 36, wherein the injection mold is provided with an injection channel which is communicated with a second discharge channel 212, and two sides of the injection channel 311 are also provided with a plurality of groups of connecting holes; the upper die 32, the lower die 33, the first side die 34 and the second side die 35 are positioned on one side of the injection die 31 far away from the second discharging channel 212, and form an injection molding cavity 37 of the molding host 30 together with the injection die 31; the core-pulling shaft 36 penetrates through the connecting hole and extends into the injection cavity 37, and the core-pulling shaft 36 can rotate in the connecting hole. In this embodiment, the upper mold 32, the lower mold 33, the first side mold 34 and the second side mold 35 are all flexible conveyor belts, specifically, a pair of transmission gears are fixedly provided on the upper side, the lower side, the left side and the right side (referring to the direction in fig. 4) of the material injection channel, a transmission chain is laid on the transmission gears, and the flexible conveyor belts are laid on the outer sides of the transmission chains.

Because the production raw slurry for producing the gypsum light hollow partition plate has the characteristic of quick solidification, after the production raw slurry enters the injection molding cavity 37, the production raw slurry can be quickly solidified, and the solidified gypsum light hollow partition plate can move to one side far away from the molding host 30 under the drive of the soft conveying belt and finally is cut and stored, so that the production continuity is improved, and a set of dies can be used for continuous production, so that the production efficiency is improved.

The large-diameter section is used for core pulling of the gypsum light hollow partition board, and the distance between the outer circumferential surfaces of the large-diameter sections of the two core pulling shafts 36 in each group is smaller than 1mm. Because the distance between the outer circumferential surfaces of the large-diameter sections of the two loose core shafts 36 in each group is smaller than 1mm, when the production raw slurry is attached to the outer circumferential surfaces of the large-diameter sections of the loose core shafts 36, the production raw slurry attached to the surfaces of each group is carried along by friction force generated during rotation between the loose core shafts 36 in each group, so that the cleanliness of the loose core shafts 36 is ensured. This will not occur as a result of the surface condensation of the production stock due to the long run of the withdrawal mandrel 36, which results in an ever larger core opening of the gypsum light weight hollow partition panel and ultimately a reduced strength of the gypsum light weight hollow partition panel. Meanwhile, in this embodiment, in order to further reduce the adhesion of the outer circumferential surface of the core-pulling shaft 36 to the production stock, the core-pulling shaft 36 is made of a nonpolar metal material, i.e., the core-pulling shaft 36 is made of a material having non-adhesive properties, such as modified polyetheretherketone, ST, or modified polytetrafluoroethylene.

Wherein, one waist-shaped hole 42 of at least two groups of waist-shaped holes 42 is respectively arranged in the elliptical grooves 43, the short axis direction of the elliptical grooves 43 is consistent with the length direction of the waist-shaped holes 42, and a plurality of elliptical grooves 43 are symmetrically distributed with the longitudinal symmetry axis of the material cleaning plate 40. In this embodiment, a cam 44 is further provided, the cam 44 is fixedly connected with the mandrel and is located in the elliptical groove 43, and a rotation radius of one end of the cam 44 away from the rotation center is adapted to a long axis radius of the elliptical groove 43, so that the cam 44 rotates along with the mandrel in the elliptical groove 43 to drive the cleaning plate to reciprocate up and down on the mandrel, and because the cleaning plate is disposed at an outlet of the injection channel 311 close to the injection mold 31, when the cleaning plate 40 reciprocates up and down, the injection molding primary slurry attached to one side of the injection mold 31 close to the injection molding cavity 37 is cleaned, thereby avoiding solidification of the injection primary slurry at the position, affecting smoothness of the injection molding channel 311, and avoiding that the soft belt is affected by the soft belt conveying due to the inherent injection primary slurry solidified on one side of the injection mold 31 close to the injection molding cavity 37. It will be appreciated by those skilled in the art that the elliptical grooves 43 are symmetrical about the longitudinal symmetry axis of the purge plate 40 to ensure smooth up and down operation of the purge plate, and that the number of elliptical grooves 43 may be two or four, and in this embodiment is preferably four. In this embodiment, a clearing block 361 is fixedly arranged on the mandrel, the clearing block 361 is fixedly connected with one side of the small diameter section of the mandrel, which is close to the oversized diameter section, and the clearing block 361 can clear attachments on one side of the clearing plate 40, which is far away from the injection mold 31, along with the rotation of the mandrel, so that the smoothness of the gypsum light hollow partition board after the soft belt is conveyed and molded is further ensured, the continuity of production is ensured, and the production efficiency is improved. In the present application, in order to reduce adhesion of the purge plate 40 to the injection molding stock, the purge plate 40 is preferably made of a non-adhesive material.
