Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
Example 1
The spiral auger drying device is used for stirring and drying kitchen waste, namely, the kitchen waste to be treated is placed in a charging barrel of the spiral auger drying device, the kitchen waste is fully stirred by a spiral auger assembly of the spiral auger drying device, and meanwhile, the drying device of the spiral auger drying device is heated and heated, so that the kitchen waste inside the drying device is heated and dried, and the purpose of quickly and fully drying the kitchen waste is achieved.
Specifically, spiral auger drying device includes: the drying device comprises a charging barrel, a spiral auger assembly, a feeding hole, a discharging hole, a drying unit, a driving unit, a conveying unit and a control unit.
Wherein, a feed inlet and a discharge outlet are arranged on the charging barrel; the discharge port is positioned in the pushing direction of the spiral auger assembly; the feed inlet and the discharge outlet can be both the open pores arranged on the outer wall of the charging barrel, and the positions can be selected according to specific requirements. In the embodiment, the feeding hole can be arranged at the top of the charging barrel, so that feeding is convenient; the discharge port can be arranged at the bottom of the charging barrel or at the position close to the lower side wall of the charging barrel, namely at the position slightly close to the lower side wall of the pushing direction of the spiral auger assembly, so that the discharging is convenient, and the aim of quickly and completely discharging is fulfilled. The size, mode, shape and the like of the opening of the feeding hole and the discharging hole can be selected according to different requirements, and are not limited herein.
The spiral auger assembly is connected with the driving unit through the conveying unit; the conveying unit and the driving unit are both located outside the charging barrel and used for providing stirring power, for example, the driving unit is a motor, and the conveying unit can be a transmission shaft and the like. The input end of the spiral auger assembly is connected with the transmission unit through gear engagement, so that transmission of different moments can be realized, the moment transmission in the coaxial or vertical direction can be realized, and the gear combination can be selected according to the installation direction or position of the driving unit and the transmission unit.
In addition, the spiral auger assembly is arranged in the charging barrel, and a concave channel is arranged at the bottom of the charging barrel; a preset gap exists between the side wall of the concave channel and the rotating track of the spiral auger assembly, namely, the concave channel is matched with the spiral blade and a reserved gap is arranged. Different from the traditional charging barrel with the stirring shaft and the like, in the embodiment, the bottom in the charging barrel needs to form a concave channel, such as a U shape, a spiral auger assembly is arranged above the bottom of each concave channel, a reserved gap between a spiral blade in the spiral auger assembly and the bottom of the U shape is kept in a smaller range, a stirring dead zone is prevented from being formed between the spiral auger assembly and the bottom of the charging barrel during the rotary stirring process, materials are accumulated at the bottom of the charging barrel, the rotary stirring cannot be driven by the spiral blade of the spiral auger assembly, the insufficient stirring is further avoided, and the drying effect is influenced.
In other embodiments than this, instead of using a U-shaped bottom, a plurality of U-shaped bottoms or a plurality of U-shaped bottoms may be used, that is, the above-mentioned solutions belong to a general inventive concept, and the protection scope of the present application is not departing from the inventive idea of the present application.
In order to achieve the above purpose of sufficient stirring and fast drying, the structure of the spiral auger assembly needs to be redesigned in addition to the need of changing the shape of the bottom of the charging barrel.
Specifically, spiral auger subassembly includes pivot and multiunit helical blade. The single group of helical blades are arranged on the outer surface of the rotating shaft, and when the single group of helical blades rotate along with the rotating shaft, the single group of helical blades can form curved surface spiral rotation, so that a circle of kitchen waste around the single group of helical blades is driven to turn over. The multiple sets of helical blades are arranged on the rotating shaft at intervals, namely, the helical blades keep a preset distance between every two helical blades.
Because helical blade only plays the purpose of stirring the kitchen discarded object, can't smash or broken effect, consequently, arrange at least one blade disc on helical blade interval two by two. The cutter head is also arranged on the outer surface of the rotating shaft and can rotate along with the rotation of the rotating shaft, and the other side of the cutter head is provided with a crushing blade, so that large blocks or caking objects in kitchen waste can be crushed, and the efficiency and the effect of squeezing and dewatering are improved.

The working principle of the device is as follows: the control unit starts a rotating shaft in the spiral auger assembly to rotate through the driving unit and the conveying unit, so as to drive the spiral blades and the cutter head to rotate, meanwhile, kitchen waste containing a large amount of moisture is added into the charging barrel through the feeding port, the kitchen waste is fully stirred through the spiral auger assembly, the kitchen waste can be uniformly distributed in a concave channel (barrel wall) of the charging barrel, at the moment, the drying unit is used for heating, the drying effect can be ensured while the kitchen waste is fully and uniformly stirred, and the purposes of full stirring and quick drying are achieved; after the driving unit works for a period of time, namely after the driving unit is completely dried, the discharge port is opened, and the kitchen waste is driven by the helical blade to be output from the discharge port.
Example 2
Referring to fig. 1 and 2, a spiral auger drying device includes: the device comprises a charging barrel 1, a pair of spiral auger assemblies 2, a feeding port 11, a discharging port 12, a drying unit 3, a driving unit 10, a conveying unit 101 and a control unit. On the basis of embodiment 1, the present embodiment further optimizes the structures of the auger assembly 2, the gear engagement assembly, the drying unit 3, the conveying unit 101 and the charging barrel 1 to further improve the drying effect.
1) Structure optimization of spiral auger assembly 2 and bottom of charging barrel
In this embodiment, for convenience and brevity of describing the invention of the present application, the following description will be made in detail by citing a scheme that the cartridge adopts a double U-shaped bottom, or a so-called W-like bottom.
In this embodiment, the bottom of the charging barrel adopts a W-like (double U-shaped) structure, so 2 rotating shafts are required to be equipped to correspond to two U-shaped bottoms of the W-shape.
In order to avoid the situation that the helical blades on the two rotating shafts and the cutter head are overlapped and collided when rotating, the helical blades on the two rotating shafts and the cutter head can be arranged at intervals or in a staggered mode, namely, the helical blades on one rotating shaft and the cutter head are different in rotating phase or staggered, namely, when the helical blades on the other rotating shaft and the cutter head are rotated to one side, the helical blades on the other rotating shaft and the cutter head are rotated to the other side or staggered in phase, and only the helical blades on the different rotating shafts are required to be prevented from colliding. Preferably, the spiral auger assembly is ensured to form an intermittently arranged auger shape. In addition, the arrangement modes of the helical blades and the cutter heads on different rotating shafts can be set according to specific conditions. The specific scheme is as follows:
in the embodiment, the two spiral auger components are a driving spiral auger shaft system 24 and a driven spiral auger shaft system 25 respectively; the driving spiral auger shaft system 24 is connected with the driving unit 10 through the transmission unit 101; the input ends of the movable spiral auger shaft system 24 and the driven spiral auger shaft system 25 are connected through a gear meshing component; the input ends of the two shafting are connected through a gear meshing component; the transmission unit is connected with the input end of the driving spiral auger shaft system 24 through a gear meshing component. Similarly, the driving spiral auger shaft system 24 and the driven spiral auger shaft system 25 are both arranged in the charging barrel 1; the driving spiral auger shaft system 24 and the driven spiral auger shaft system 25 both comprise a rotating shaft 21 and a helical blade 22; the center line between the adjacent rotating shafts 21 is positioned on the helical blade 22; the helical blades 22 are arranged on the outer surface of the rotating shaft 21 at intervals, and a rotating phase difference exists between the helical blades of the helical auger shaft system 24 and the helical blades of the driven helical auger shaft system 25, and the helical blades are arranged in a staggered mode.
In the embodiment, the gaps of the spiral auger assemblies on the adjacent rotating shafts are crossed, the spiral blades on the same rotating shaft are arranged at intervals, and an interval is formed between every two adjacent spiral blades on the same rotating shaft; the spiral blades on the two rotating shafts have a rotation phase difference, so that the spiral blades and the cutter head are driven to rotate when the two rotating shafts rotate, no collision occurs, and continuous stirring and pushing are realized. Above-mentioned structural design's purpose on the one hand is during the propelling movement, and the kitchen discarded object that the intensive extrusion stirring contains a large amount of moisture, and on the other hand realizes intensive mixing, improves drying efficiency. And the drying unit can heat the kitchen waste in the charging barrel in all directions. Therefore, the drying effect and efficiency are improved by the structural design.
In this embodiment, the bottom of the cartridge forms two parallel and closely adjacent U-shaped channels, otherwise known as concave channels; u-shaped passageway and helical blade cooperation, the circular cross section orbit that forms when helical blade rotates promptly can be hugged closely with the semi-circular cross section of single U-shaped passageway bottom, avoids forming stirring "blind spot", avoids helical blade to touch the situation of feed cylinder bottom infinitely among the prior art promptly, further avoids kitchen waste to pile up in the feed cylinder bottom, the situation that can't be fully stirred. The stirring "dead zone" is located the feed cylinder below and is located the region outside the helical blade rotation orbit, and the kitchen discarded object in this region can't be stirred by helical blade, and the kitchen discarded object in this region is heated inhomogeneous, also can't be pushed to the discharge gate. As shown in fig. 2, a portion of the concave channel near the discharge port 12 is inclined downward to the discharge port 12, i.e., a portion of the concave channel near the discharge port 12 forms an inclined portion 15. The inclined parts 15 of two adjacent concave channels are connected and integrally formed, and the dried kitchen waste smoothly inclines and slides into the discharge hole 12.
In this embodiment, the driving auger shaft system 24 and the driven auger shaft system 25 can rotate forward and backward.
When the driving spiral auger shaft system 24 and the driven spiral auger shaft system 25 rotate forwards, the two shaft systems rotate oppositely to stir the kitchen waste and push the kitchen waste towards one end of the discharge port 12, the kitchen waste is gradually accumulated, and the kitchen waste is extruded in a space between the charging barrel 1 and the shaft systems to realize extrusion and dehydration; the driving spiral auger shaft system 24 and the driven spiral auger shaft system 25 can realize pushing and further extrude the kitchen waste through the action between the driving spiral auger shaft system and the charging barrel 11; after the driving unit 10 operates for a period of time, the kitchen waste is gradually pushed to the discharge port 12 under the action of the helical blades 22, at this time, the driving helical auger shaft system 24 and the driven helical auger shaft system 25 run in reverse under the action of the control unit, and the kitchen waste is uniformly pushed to the other end under the action of the two sets of helical blades 22. Therefore, the materials can be quickly dried by repeated actions.
In other embodiments, the helical blades 22 of the driving auger shaft system 24 and the driven auger shaft system 25 are arranged in opposite helical directions.
As shown in fig. 3 to 4, the driving screw auger shaft system 24 includes a rotating shaft 21, a fixing and positioning device is installed on the cutter head 23, the positioning device radially penetrates through the rotating shaft 21, one end of the positioning device is fixed on the rotating shaft 21 through a nut, and an adjusting gasket is sleeved on a section of the positioning device fixing the cutter head 23 and installed on the rotating shaft 21.
