Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically a screw conveyor for feeding chili powder preparation. Background Technology

[0002] The conventional screw conveyor used in the existing chili powder preparation feeding process is prone to clumping of chili powder entering the conveyor during the conveying process. This clumping problem is mainly caused by two factors: one is the intrusion of external moisture or condensation inside the equipment, which causes the chili powder to absorb moisture and agglomerate, forming wet clumps; the other is that the high temperature generated during the conveying process causes the chili oil contained in the chili powder to soften and seep out, and the oil binds the dry powder together to form a clump structure. The above-mentioned clumping phenomenon directly leads to a decrease in the discharge stability of the screw conveyor, and the discharge accuracy fluctuates significantly, making it difficult to achieve uniform and stable quantitative feeding. This, in turn, adversely affects the production quality of subsequent chili powder preparation processes, restricting the overall operation efficiency and finished product quality of the chili powder preparation production line. Therefore, this invention provides a screw conveyor for chili powder preparation feeding. Summary of the Invention

[0003] The purpose of this invention is to provide a screw conveyor for feeding chili powder preparation, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: a screw conveyor for feeding chili powder preparation, comprising a screw conveyor body, a main material box at the top of the screw conveyor body, a feed pipe connected to the side wall of the main material box, a feeding pipe connected between the main material box and the feed pipe, an elastic filter plate inside the feed pipe, two symmetrical micro vibration motors fixedly installed at the bottom of the elastic filter plate, a receiving cylinder rotatably connected to the inner cavity of the main material box, a plurality of distribution pools circumferentially formed at equal intervals at the top of the receiving cylinder, a sleeve rotatably connected to the bottom of the inner cavity of each distribution pool, a main rod body slidably arranged inside each sleeve, a circular plate welded to the top of each main rod body, and circumferentially welded at equal intervals on each circular plate. Equipped with several blades, this device initially crushes chili powder clumps using high-speed rotating blades that move up and down, effectively improving the crushing effect. Then, dry gas is introduced into the crushed chili powder for drying. During this process, the blades rotate slowly and move up and down, agitating the chili powder to accelerate moisture removal and, in conjunction with related structures, conveying the bottom chili powder to the top, ensuring that the moisture trapped in the bottom powder is fully discharged. Subsequently, coolant is supplied to the outer wall of the chili powder chamber. The centrifugal force generated by the rotating blades causes the chili powder to adhere tightly to the chamber wall, significantly improving the cooling effect. Simultaneously, the rotating blades further break up clumps formed by grease adhesion, comprehensively optimizing the chili powder processing effect.

[0005] Preferably, a drive motor is fixedly installed at the bottom of the inner cavity of the receiving cylinder, a gear is fixedly installed at the top output end of the drive motor, a plurality of vertical plates are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder, an internal gear ring meshing with the gear is rotatably connected between the tops of the plurality of vertical plates, a plurality of receiving rings are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder, an external gear ring meshing with the internal gear ring is rotatably connected to the bottom of each receiving plate, and a limit rod is welded to the bottom of each external gear ring.

[0006] Preferably, a plurality of elastic telescopic rods are fixedly installed at the bottom of the inner cavity of the receiving cylinder, and a top plate is fixedly installed on the top of each pair of adjacent elastic telescopic rods. A plurality of main rods are rotatably connected to the corresponding top plate. An arc-shaped block is welded to the bottom of each top plate, and two symmetrical abutment rods are welded to the top of each top plate. A piston plate is welded between the tops of the plurality of abutment rods. A cooling cylinder is provided on the outside of each distributing pool, and a fixing plate is provided between the bottoms of the plurality of cooling cylinders.

[0007] Preferably, a plurality of columns are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder. Each column is fitted with gear two and gear three, with each gear two meshing with a corresponding external gear ring. A gear four is fixedly installed on the outer wall of each sleeve, with each gear four meshing with a corresponding gear three. A drive motor drives gear one to rotate, which in turn drives the internal gear ring to rotate. The internal gear ring then drives the external gear ring to rotate, and the external gear ring, in turn, drives gear four to rotate at high speed via gear two and gear three. Gear four then drives the sleeve, main rod, circular plate, and blade to rotate. The device rotates at high speed, using high-speed rotating blades to break up chili powder clumps. The broken chili powder moves towards the annular wall of the distribution tank under centrifugal force, while unbroken clumps are pushed to the center. The clumps then fall along the arc surface of the top column to the blades for initial crushing, thus improving the uniformity of crushing. In addition, a limiting rod rotates synchronously with the outer gear ring. During the circular motion of the limiting rod, it intermittently pushes the arc surface block, top plate, main rod, circular plate, and blades upwards. The high-speed rotating blades, moving up and down, perform a more detailed initial crushing of the chili powder clumps.

[0008] Preferably, each main rod has a main air hole at its center, and each main rod has several auxiliary air holes circumferentially spaced at equal intervals that communicate with the corresponding main air hole. Each auxiliary air hole is fixedly installed with a one-way air outlet valve. After the initial crushing operation is completed, the end of the external air supply hose is rotatably connected to the bottom of the main rod. Then, warm dry gas is supplied to the main air hole at the center of the main rod through the external air supply hose. Subsequently, the dry gas enters the bottom of the inner cavity of the distribution tank through the auxiliary air hole, thereby drying the chili powder inside the distribution tank and preventing it from clumping again.

[0009] Preferably, each of the circular plates has a top post welded to its bottom, and each top post has several mounting slots on its annular wall. Each mounting slot has an elastic movable block elastically arranged inside it. Each top post has a pressurized airflow channel connected to several adjacent mounting slots at its top. Each distribution tank has a mounting plate welded to its inner wall, and each mounting plate has a pressurized pipe rotatably connected to its bottom. Each pressurized pipe has several vent holes evenly spaced on its wall. The hose of the external cooler is connected to the water inlet pipe, and coolant is added to the interlayer between the piston plate and the fixed plate through the water inlet pipe. The drive motor drives the blade to rotate and the top plate to move up and down. The top plate drives the piston plate to move up and down through the abutment rod. The piston plate pushes the coolant in the interlayer repeatedly into the annular interlayer between the cooling cylinder and the distribution tank, thereby cooling the chili powder in the distribution tank.

[0010] Preferably, the receiving cylinder has an inlet pipe and an outlet pipe connected to the side walls at both ends, and a tilting motor is fixedly installed on the side wall of the main material box, with the output end of the tilting motor fixedly connected to the side wall of the receiving cylinder. The tilting motor drives the receiving cylinder to tilt, pouring the chili powder in the distribution pool into the main material box and the screw conveyor body, and so on.

[0011] Preferably, the inner cavity of the feed pipe is welded with a guide plate, and the inner cavity of the feeding pipe is provided with an intermittent feeding structure.

[0012] This invention provides an improved screw conveyor for feeding chili powder preparation, which has the following improvements and advantages compared with the prior art: In summary, this device initially crushes chili powder clumps using high-speed rotating blades that move up and down, effectively improving the crushing effect. Drying gas is then introduced into the crushed chili powder for drying. During this process, the blades rotate slowly and move up and down, agitating the chili powder to accelerate moisture removal and, in conjunction with related structures, conveying the bottom chili powder to the top, ensuring the full removal of moisture trapped in the bottom powder. Subsequently, coolant is supplied to the outer wall of the chamber. The centrifugal force generated by the rotating blades causes the chili powder to adhere tightly to the chamber wall, significantly improving the cooling effect. Simultaneously, the rotating blades further break up clumps formed by grease adhesion, comprehensively optimizing the chili powder processing effect. Attached Figure Description

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] This invention provides an improved screw conveyor for feeding chili powder preparation. The technical solution of this invention is as follows: like Figures 1-8As shown, a screw conveyor for feeding chili powder preparation includes a screw conveyor body 1. A main material box 2 is located at the top of the screw conveyor body 1. A feed pipe 3 is connected to the side wall of the main material box 2. A guide plate 44 is welded to the inner cavity of the feed pipe 3. A feeding pipe 4 connects the main material box 2 and the feed pipe 3. An intermittent feeding structure 45 is located inside the feeding pipe 4. An elastic filter plate 5 is located inside the feed pipe 3. Two symmetrical micro-vibration motors 6 are fixedly installed at the bottom of the elastic filter plate 5. A receiving cylinder 7 is rotatably connected to the inner cavity of the main material box 2. Several distribution pools 8 are circumferentially opened at equal intervals at the top of the receiving cylinder 7. A sleeve 9 is rotatably connected to the bottom of the inner cavity of each distribution pool 8. A main rod 10 is slidably arranged inside each sleeve 9. A circular plate 11 is welded to the top of each main rod 10. Several blades 12 are circumferentially welded at equal intervals on each circular plate 11. During use, the chili segments are crushed into powder. The chili powder is added into the feed pipe 3. First, the chili powder falls onto the elastic filter plate 5. Under the action of the micro vibration motor 6, the chili powder falls down through the filter holes on the filter plate and enters the screw conveyor body 1 through the feed pipe 3 and the main box in sequence. Then, it is conveyed to the subsequent processing device by the screw conveyor body 1. During this process, the elastic filter plate 5 intercepts the chili powder clumps that are formed by adhesion. Then, the chili powder clumps fall down along the inclined surface of the elastic filter plate 5 into the feed pipe 4. After a certain number of chili powder clumps accumulate in the feed pipe 4, the intermittent feeding structure 45 is flipped to release the accumulated chili powder clumps and let them fall into the receiving cylinder 7. Due to the conical structure in the center of the receiving cylinder 7 and the discharge end of the feed pipe 4 facing the top of the conical structure, the released chili powder clumps are dispersed into several distribution pools 8 along the inclined surface of the conical structure.

[0017] Furthermore, a drive motor 13 is fixedly installed at the bottom of the inner cavity of the receiving cylinder 7, and a gear 14 is fixedly installed at the top output end of the drive motor 13. Several vertical plates 15 are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder 7. An internal gear ring 16 that meshes with the gear 14 is rotatably connected between the tops of the vertical plates 15. Several receiving rings 17 are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder 7. An external gear ring 18 that meshes with the internal gear ring 16 is rotatably connected to the bottom of each receiving plate. Each external gear ring 17... Each of the 8 components has a limit rod 19 welded to its bottom. Several columns 27 are fixedly installed at equal intervals at the bottom of the inner cavity of the receiving cylinder 7. Each column 27 has a gear 28 and a gear 39 fixedly fitted onto its body. Several gears 28 mesh with their corresponding external gear rings 18. Each sleeve 9 has a gear 4 30 fixedly installed on its outer wall, and several gears 4 30 mesh with their corresponding gear 3 29. A drive motor 13 drives gear 14 to rotate, and gear 14 drives the internal gear... The inner gear ring 16 rotates, driving the outer gear ring 18 to rotate. The outer gear ring 18, in turn, drives the gear 4 30 to rotate at high speed via gears 28 and 29. The gear 4 30 drives the sleeve 9, main rod 10, circular plate 11, and blade 12 to rotate at high speed. The high-speed rotating blade 12 breaks up the chili powder clumps. The broken chili powder moves towards the annular wall of the distribution pool 8 under the action of centrifugal force. Unbroken clumps are pushed to the center position and then fall along the arc surface of the top column 34 to the blade 12 for initial crushing, thereby improving the uniformity of crushing. In addition, the limiting rod 19 rotates synchronously with the outer gear ring 18. During the circular motion of the limiting rod 19, it intermittently pushes the arc surface block 22, top plate 21, main rod 10, circular plate 11, and blade 12 upward. The high-speed rotating blade 12, moving up and down, performs a more detailed initial crushing operation on the chili powder clumps.

[0018] Furthermore, several elastic telescopic rods 20 are fixedly installed at the bottom of the inner cavity of the receiving cylinder 7. A top plate 21 is fixedly installed on the top of each pair of adjacent elastic telescopic rods 20, and several main rods 10 are rotatably connected to the corresponding top plates 21. An arc-shaped block 22 is welded to the bottom of each top plate 21, and two symmetrical abutment rods 23 are welded to the top of each top plate 21. A piston plate 24 is welded between the tops of several abutment rods 23. A cooling cylinder 25 is provided on the outside of each distributing pool 8, and a fixing plate 26 is provided between the bottoms of several cooling cylinders 25. Each main rod 10 has a center opening. A main air hole 31 is provided, and several auxiliary air holes 32 are evenly spaced on the circumferential wall of each main rod 10 and connected to the corresponding main air hole 31. A one-way air outlet valve 33 is fixedly installed in each auxiliary air hole 32. After the initial crushing operation is completed, the end of the external air supply hose is rotatably connected to the bottom of the main rod 10. Then, warm dry gas is supplied to the main air hole 31 in the center of the main rod 10 through the external air supply hose. The dry gas then enters the bottom of the inner cavity of the distribution tank 8 through the auxiliary air hole 32 to dry the chili powder inside the distribution tank 8 and prevent it from clumping again.

[0019] Furthermore, each circular plate 11 has a top post 34 welded to its bottom, and each top post 34 has several mounting slots 35 on its annular wall. Each mounting slot 35 has an elastic movable block 36 elastically arranged inside it. Each top post 34 has a pressurized airflow channel 37 connected to several adjacent mounting slots 35 at its top. Each material distribution tank 8 has a mounting plate 38 welded to its inner wall, and each mounting plate 38 has a pressurized pipe 39 rotatably connected to its bottom. Each pressurized pipe 39 has several vent holes 40 evenly spaced on its wall. The receiving cylinder 7 has a water inlet pipe 41 and a water outlet pipe 42 connected to the side walls at both ends, respectively. The main material box 2 has... A rotating motor 43 is fixedly installed on the wall, and the output end of the rotating motor 43 is fixedly connected to the side wall of the receiving cylinder 7. The hose of the external cooler is connected to the water inlet pipe 41, and coolant is added to the interlayer between the piston plate 24 and the fixed plate 26 through the water inlet pipe 41. The drive motor 13 drives the blade 12 to rotate and the top plate 21 to move up and down. The top plate 21 drives the piston plate 24 to move up and down through the abutment rod 23. The piston plate 24 pushes the coolant in the interlayer to repeatedly enter the annular interlayer between the cooling cylinder 25 and the distribution tank 8, thereby cooling the chili powder in the distribution tank 8.

[0020] Working principle: During use, chili powder formed by crushing chili segments is added to the feed pipe 3. First, the chili powder falls onto the elastic filter plate 5. Under the action of the micro vibration motor 6, the chili powder falls downward through the filter holes on the filter plate and enters the screw conveyor body 1 through the feed pipe 3 and the main box. Then, it is conveyed to the subsequent processing device by the screw conveyor body 1. During this process, the elastic filter plate 5 intercepts the chili powder clumps that are formed by adhesion. Then, the chili powder clumps fall along the inclined surface of the elastic filter plate 5 into the feed pipe 4. After a certain number of chili powder clumps accumulate in the feed pipe 4, the intermittent feeding structure 45 flips to release the accumulated chili powder clumps, allowing them to fall into the receiving cylinder 7. Due to the conical structure in the center of the receiving cylinder 7 and the discharge end of the feed pipe 4 facing the top of the conical structure, the released chili powder clumps are dispersed into several distribution pools 8 along the inclined surface of the conical structure. Then, the drive motor 13 drives the gear 14 to rotate. 14 drives the internal gear ring 16 to rotate, which in turn drives the external gear ring 18 to rotate. The external gear ring 18 then drives the gear 4 30 to rotate at high speed via gear 28 and gear 3 29. The gear 4 30 drives the sleeve 9, main rod 10, circular plate 11, and blade 12 to rotate at high speed. The high-speed rotating blade 12 breaks up the chili powder clumps. The broken chili powder moves towards the ring wall of the distribution tank 8 under the action of centrifugal force, while the unbroken clumps... The block is pushed to the center position, and then the block falls along the arc surface of the top of the top column 34 to the blade 12, thus performing the initial crushing operation to improve the uniformity of crushing; in addition, the limit rod 19 is set to rotate synchronously with the outer gear ring 18. During the circumferential movement of the limit rod 19, it will intermittently push the arc block 22, the top plate 21, the main rod body 10, the circular plate 11 and the blade 12 upward, and the high-speed rotating blade 12 moving up and down will perform a more detailed initial crushing operation on the chili powder block; After the initial crushing operation is completed, the end of the external air supply hose is rotatably connected to the bottom of the main rod 10. Warm, dry gas is then supplied through the external air supply hose to the main air hole 31 at the center of the main rod 10. The dry gas then enters the bottom of the distribution tank 8 through the auxiliary air hole 32 to dry the chili powder inside the distribution tank 8, preventing secondary clumping. Simultaneously, the drive motor 13 drives the blades 12 and the top column 34 to slowly rotate and reciprocate up and down. The moving blades 12 agitate the chili powder in the distribution tank 8, making it easier for the dry gas at the bottom to carry away moisture. Furthermore, when the top column 34 is initially in its position, its annular wall... The edge area can pick up some of the chili powder located at the bottom. As the top column 34 moves upward, the pressure boosting pipe 39 extends into the pressure boosting airflow channel 37. Initially, the gas in the pressure boosting airflow channel 37 is discharged through the auxiliary air hole 32. When the top column 34 moves to the top area, the auxiliary air hole 32 is completely displaced into the pressure boosting airflow channel 37. At this time, the pressure boosting pipe 39 moves downward, which will increase the air pressure in the pressure boosting airflow channel 37. This causes the elastic movable block 36 to move outward due to the increased air pressure, thereby transferring the chili powder at the bottom of the inner cavity of the distribution tank 8 to the top. This cycle repeats, allowing the moisture carried by the chili powder at the bottom to be discharged smoothly. Subsequently, the external cooler... The hose is connected to the water inlet pipe 41, and coolant is added to the interlayer between the piston plate 24 and the fixed plate 26 through the water inlet pipe 41. The drive motor 13 drives the blade 12 to rotate and the top plate 21 to move up and down. The top plate 21 drives the piston plate 24 to move up and down through the abutment rod 23. The piston plate 24 pushes the coolant in the interlayer to repeatedly enter the annular interlayer between the cooling cylinder 25 and the distribution tank 8, thereby cooling the chili powder in the distribution tank 8. The high-speed rotating blade 12 acts on the chili powder in the distribution tank 8, causing the chili powder to stick tightly to the inner annular wall of the distribution tank 8 under the action of centrifugal force. This creates an inverted cone-shaped hollow area in the center of the distribution tank 8, which further enhances the cooling effect of the coolant on the chili powder in the distribution tank 8. At the same time, the high-speed rotating blades 12 can effectively break up the clumps of chili powder formed by the high temperature adhesion of oil in the distribution tank 8. After the cooling operation is completed, the coolant is pushed by the piston plate 24 and discharged from the main body of the device through the water hole at the top of the cooling cylinder 25 and the water outlet pipe 42 connected to the external cooler hose. Finally, the set tilting motor 43 drives the receiving cylinder 7 to tilt, pouring the chili powder in the distribution tank 8 into the main material box 2 and the screw conveyor body 1, and so on.
