Description

Technical Field

[0001] This application relates to screw conveyors, and more particularly to residue-free screw conveyor discharge devices for high-viscosity mash. Background Technology

[0002] High-viscosity mash is commonly found in the food, fermentation, and chemical industries, such as malt mash in beer brewing and gelatinized mash in starch processing.

[0003] A current patent (publication number: CN 213201211 U) discloses a screw conveyor device, including a reinforced base and a first discharge port. Each reinforced base has legs with anti-slip pads underneath. A cylindrical outer shell is located above the reinforced base, and a rotating shaft is located inside the cylindrical shell. Spiral blades are arranged on the outer side of the rotating shaft. A first feed port is located above the cylindrical shell, and a mounting block with a sealing strip is located above each mounting block. This screw conveyor device, by using spiral blades, allows for forward and reverse rotation of the spiral blades via a control switch on a control panel. Because the device has multiple feed ports and multiple discharge ports, it achieves flexible material conveying. Since the spiral blades can rotate in both directions, material blockage is avoided, improving the device's applicability.

[0004] While the device described in the aforementioned comparative document solves the problems of cumbersome material handling and low conveying efficiency of traditional conveying devices, it also has drawbacks when used with high-viscosity mash. The mash tends to adhere to the screw blades and the inner wall of the conveyor housing, resulting in a large amount of residual mash inside the conveyor after each conveying cycle. This not only wastes raw materials but also increases production costs. To address these issues, a residue-free screw conveyor discharge device for high-viscosity mash is proposed. Utility Model Content

[0005] The purpose of this application is to provide a residue-free screw conveyor discharge device for high-viscosity mash, which has advantages such as a cleaning structure. It solves the problem that when using high-viscosity mash, a large amount of mash remains in the conveyor after each conveying, which not only wastes raw materials but also increases production costs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This residue-free screw conveyor discharge device for high-viscosity mash uses an air inlet pipe, a hollow pipe, and a one-way nozzle. When using high-viscosity mash, the air inlet pipe allows gas to be injected into the hollow pipe, and the one-way nozzle directs the compressed gas through the nozzle. During the conveying process, this compressed gas continuously disrupts the adhesion interface between the mash and the screw blades or cylinder wall. Simultaneously, the low-adhesion biomimetic coating significantly reduces the viscosity of the high-viscosity mash. Combined with periodic blowing of compressed air through the hollow pipe and one-way nozzle, residual materials can be forcibly removed, solving the clogging and residue problems caused by the viscosity of materials in traditional screw conveyors.

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

A hollow tube 103 is tightly nested inside the cylinder 1 via bearings. A spiral blade 104 and a first gear 107 are fixedly connected to the surface of the hollow tube 103. Multiple one-way nozzles 105 are provided on the surface of the hollow tube 103. The one-way nozzles 105 and the spiral blades 104 are all inside the cylinder 1. The first gear 107 is inside the fixed shell 102. Multiple L-shaped support rods 1012 are fixedly connected to the other side of the fixed shell 102. A rotary joint 1013 is fixedly connected between the multiple L-shaped support rods 1012.

The input end is fixedly connected to an air inlet pipe 1014. The surface of the spiral blade 104 is coated with a low-adhesion biomimetic coating 106. Through the air inlet pipe 1014, hollow pipe 103 and one-way nozzle 105, gas can be injected into the hollow pipe 103 under the action of the air inlet pipe 1014. Then, under the action of the one-way nozzle 105, the compressed gas can be directionally sprayed through the one-way nozzle 105. During the conveying process, the adhesion interface between the mash and the spiral blade 104 or the cylinder wall can be continuously broken. At the same time, under the action of the low-adhesion biomimetic coating 106, the viscosity of the high-viscosity mash can be significantly reduced. Then, combined with the periodic blowing of compressed air through the hollow pipe 103 and one-way nozzle 105, residual materials can be forcibly stripped off, solving the problem of blockage and residue caused by the viscosity of materials in traditional screw conveyors.

The top of the L-shaped plate 205 overlaps the bottom of the placement ring 4. By sliding the L-shaped plate 205 up and down within the L-shaped groove 204, the filter frame 401 can be vibrated, preventing the material inside the filter frame 401 from clogging. A stepper motor 209 is fixedly connected to the side of the fixed frame 203.

The surfaces of the cams 2011 overlap the bottom of the contact pad 206. By setting a stepper motor 209, the operation of the stepper motor 209 can rotate the rotating shaft 2010 and the cams 2011. The cam 2011 mechanism can convert the rotation of the stepper motor 209 into regular vibration of the L-shaped plate 205, which can make the filter frame 401 vibrate continuously. A slide rod 207 is fixedly connected to the top of the L-shaped groove 204. An L-shaped plate 205 is slidably connected to the surface of the slide rod 207. A limit spring 208 is fitted on the surface of the slide rod 207.

The discharge pipe 101 is fixedly connected to the surface of the cylinder 1. By setting the discharge pipe 101, the inclination angle can be used to reduce end residue.

[0043] The implementation principle of this application embodiment is as follows: In use, the raw materials are poured into the feed hopper 201. Under the action of the filter frame 401, large impurities in the raw materials can be filtered. At the same time, the stepper motor 209 runs, which can make the rotating shaft 2010 and the cam 2011 rotate. Through the rotation of the cam 2011, the L-shaped plate 205 can be vibrated. Then, in conjunction with the slide rod 207 and the limit spring 208, the L-shaped plate 205 can move up and down in the L-shaped groove 204. Through the movement of the L-shaped plate 205, the filter frame 401 can be vibrated, thereby preventing the raw materials in the filter frame 401 from clogging. The filtered raw materials can flow into the cylinder 1 through the connecting hose 3. Then, the rotating motor 1011 runs, which can make the rotating rod 108 and the second gear 109 rotate. Through the transmission of the gear chain 1010, the first gear 107 and the rotating rod 108 can be driven to rotate, which can make the spiral blade 104 rotate.
