Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a foaming device on a sponge production line includes a foaming box 1, a feeding pipe 24 and a discharging pipe 25 are arranged on the foaming box 1, and opening and closing valves are respectively installed in the feeding pipe 24 and the discharging pipe 25. A hollow shaft 8 is rotatably connected in the foaming box 1, the hollow shaft 8 is connected with an annular pipe 9 through a supporting pipe 16, the number of the supporting pipes 16 and the number of the annular pipe 9 are at least two, the outer wall of the annular pipe 9 is connected with a rotating ring 10 in a sealing and rotating mode, a plurality of limiting rings 21 are welded on the side wall of the annular pipe 9, and every two adjacent limiting rings 21 are arranged on two sides of the rotating ring 10.
And a plurality of hollow stirring leaves 11 of fixedly connected with on the rotating ring 10 lateral wall, and a plurality of first through-holes 14 have been seted up to the lateral wall of ring tube 9, a plurality of second through-holes 15 have been seted up to the lateral wall of rotating ring 10, venthole 12 has been seted up to the lateral wall of hollow stirring leaf 11, install the slewing mechanism who makes rotating ring 10 pivoted in the ring tube 9, foaming box 1 upper end fixedly connected with transmission case 2, set up centrifugal fan 3 in the transmission case 2, and centrifugal fan 3 passes through transmission mechanism and is connected with quill shaft 8, transmission mechanism includes intermeshing's driving gear 5 and driven gear 4, and the pivot fixed connection of driving gear 5 and centrifugal fan 3, driven gear 4 and quill shaft 8 fixed connection, and driving gear 5 size is less than driven gear 4's size. Therefore, when the centrifugal fan 3 rotates at a high speed, the torque can be transmitted to the hollow shaft 8 at a low speed through the transmission mechanism, the mixed liquid material can be stirred relatively slowly and can be uniformly mixed, and the phenomenon of layering caused by overlarge centrifugal force of the liquid in the centrifugal fan can be avoided.
An air inlet 6 is formed in the upper end of the transmission case 2, an exhaust pipe 7 is arranged on the side wall of the transmission case 2, and the exhaust pipe 7 is communicated with the hollow shaft 8 through a rotary joint 13. It should be noted that, through setting up drive mechanism, can make this device match the stirring speed and the gas injection speed of liquid, so when increasing air flow rate for the increase air is at the inside flow distance of liquid material, then the stirring speed is also faster, so can make the air of pouring into in the liquid material form behind the bubble can not escape immediately in liquid, the bubble can flow a period along with the liquid of rapid mixing, so can prolong the mixing time of air and liquid material, and then improve the mixed effect of air to liquid material.
The rotating mechanism comprises a telescopic air bag 17 arranged in the annular pipe 9, two ends of the telescopic air bag 17 are respectively provided with an air outlet pipe 18 communicated with the inside of the telescopic air bag, the side wall of the air outlet pipe 18 is fixedly connected with a first magnetic plate 19 and a second magnetic plate 20, the side wall of the rotating ring 10 is embedded with an iron sheet 23, the supporting pipe 16 is communicated with the telescopic air bag 17 and the hollow shaft 8, and an electromagnetic valve 22 is arranged in the supporting pipe 16. It should be noted that the solenoid valves 22 in the two support tubes 16 are opened and closed alternately, that is, air is alternately supplied to the two support tubes 16 and alternately enters the corresponding telescopic air bags 17. The sum of the sectional areas of the two air outlet pipes 18 is smaller than the sectional area of the support pipe 16, so that the air inlet amount in unit time of the support pipe 16 is larger than the integral air outlet amount of the two air outlet pipes 18.
And two ends of the supporting tube 16 are respectively fixedly connected with the hollow shaft 8 and the annular tube 9.
Referring specifically to fig. 3, the support tube 16 has an upper end that penetrates the side wall of the annular tube 9 and is in sealed communication with the bellows 17, and a lower end that communicates with the interior of the hollow shaft 8. Since the sum of the sectional areas of the two air outlet pipes 18 is larger than the sectional area of the support pipe 16, the flow rate of the air input into the telescopic air bag 17 from the support pipe 16 is larger than the flow rate of the air output from the air outlet pipe 18 in unit time, so that the air in the telescopic air bag 17 is accumulated to cause the air pressure in the telescopic air bag 17 to rise in the input process of the air, the telescopic air bag 17 expands and extends at the moment, the electromagnetic valve 22 in the support pipe 16 is closed, and when the input of the air flow is stopped, the telescopic air bag 17 contracts by means of the elasticity of the telescopic air bag 17 and continuously extrudes the air in the telescopic air bag along the air outlet pipe 18. Therefore, although the two solenoid valves 22 are opened and closed alternately, the air outlet pipe 18 can keep exhausting continuously, that is, the device can continuously supply air to the liquid material.
In the present invention, the centrifugal fan 3 is started to continuously suck air from the air inlet 6 and supply the air into the hollow shaft 8 along the air discharge pipe 7. And the centrifugal fan 3 will drive the driving gear 5 to rotate when rotating, and make the driven gear 4 which is meshed with the driving gear and has larger size rotate slowly, then the driven gear 4 will drive the hollow shaft 8 to rotate slowly. The hollow shaft 8 can rotate with the annular tube 9 via the support tube 16.
Furthermore, the air flow from the exhaust pipe 7 will be discharged into the hollow shaft 8 via the rotary joint 13, and the solenoid valves 22 in the two support pipes 16 will be opened and closed in sequence. The air flow will be discharged along the two support tubes 16 into the telescopic air bags 17 in the upper and lower annular tubes 9 in sequence and alternately. Thus, for the same bellows 17, the gas flow is fed intermittently.
When the air flow is discharged into a certain telescopic air bag 17, the air flow is also discharged from the air outlet pipes 18 at the two ends of the telescopic air bag 17, and because the sum of the air outlet areas of the two air outlet pipes 18 is smaller than the air inlet area of the supporting pipe 16, namely the air inlet amount of the supporting pipe 16 in unit time is larger than the air outlet amounts of the two air outlet pipes 18, the air pressure in the telescopic air bag 17 is increased, and the telescopic air bag 17 is expanded. When the air flow stops, the telescopic air bag 17 gradually contracts under the action of the elasticity of the telescopic air bag, and the air in the telescopic air bag is continuously extruded outwards through the air outlet pipe 18. Therefore, the telescopic air bag 17 will be continuously telescopic in the whole process.
And the telescopic air bag 17 can continuously push and pull the air outlet pipes 18 at two sides to move along the inner wall of the annular pipe 9 in the telescopic process, and at the moment, the first magnetic plate 19 and the second magnetic plate 20 on the side wall of the air outlet pipe 18 sequentially and repeatedly pass through the inside of the rotating ring 10.
When the first magnetic plate 19 passes through the inside of the rotating ring 10, the first magnetic plate 19 can attract the iron sheet 23 on the rotating ring 10 to approach and attach to the same, and similarly, when the second magnetic plate 20 passes through the inside of the rotating ring 10, the iron sheet 23 can also be attracted to approach and attach to the same. Because the first magnetic plate 19 and the second magnetic plate 20 are arranged at different positions on two sides of the air outlet pipe 18, when the first magnetic plate 19 and the second magnetic plate 20 sequentially and reciprocally penetrate through the inside of the rotating ring 10, the rotating ring 10 can be rotated back and forth by attracting the iron sheet 23, and the rotating ring 10 drives the hollow stirring blades 11 to synchronously rotate back and forth. During the rotation of the rotating ring 10, the first through holes 14 are continuously communicated with the second through holes 15.
The air discharged from the air outlet pipe 18 is input into the hollow stirring vane 11 through the first through hole 14 and the second through hole 15, and is finally discharged from the air outlet hole 12.
In summary, the hollow stirring blade 11 of the present device can rotate around the hollow shaft 8 along with the annular tube 9, and can also be rotated by the rotating ring 10. Each hollow stirring blade 11 can contact with all parts of liquid materials in the foaming box 1 in the rotating process, so that air exhausted from the upper part of each hollow stirring blade 11 and the air outlet 12 can fully contact with all parts of the liquid materials, the mixing effect of the air and the liquid materials is greatly improved, and the foaming reaction rate is accelerated. In addition, the hollow stirring blades 11 can continuously break the liquid material in the rotating process, so that when the air is discharged from the air outlet 12, the resistance of the liquid material to the discharged air can be effectively reduced, the air flow can flow in the liquid material for a longer distance, and the air can be in contact with more liquid materials to improve the mixing efficiency.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
