Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral conveyor belt technology, specifically to a spiral conveyor belt device. Background Technology
[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation and convenient closed transportation. Screw conveyors are divided into two types in terms of conveying form: shafted screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors. They are commonly used to convey powdery, granular and lumpy materials to different locations.
[0003] As disclosed in Chinese Patent Publication No. (CN222118007U), a novel spiral conveyor belt mechanism belongs to the field of spiral conveyor belt technology. This novel spiral conveyor belt mechanism includes a housing. The inner walls of the left and right sides of the housing are provided with cleaning mechanisms to improve the anti-caking and cleaning effect. This utility model, through the interaction of the cleaning mechanisms, shaft tube, spiral blades, scrapers, drive components, and flushing components, and the action of the scrapers and flushing components, cleans the attachments on the spiral blades and the inner walls of the housing, reducing resistance during conveying and improving conveying efficiency. The scrapers and flushing components effectively remove clumps of material on the inner walls of the housing, reducing the impact of clumps on the conveyor belt mechanism and extending the service life of the equipment. Regular cleaning can keep the inside of the equipment clean, preventing dust or impurities from affecting the normal operation of the equipment, and improving the reliability and stability of the equipment.
[0004] As described in the aforementioned patent, the scraper and flushing components can clean the attachments on the spiral blades and the inner wall of the housing. However, when the flushing components in this structure are flushing the inside of the housing, the material inside the housing will clog the flushing components, and it is not easy to clean them after clogging. When the conveying distance is long, the inspection and cleaning efficiency is low, which affects the conveying efficiency. Therefore, we propose a spiral conveyor belt device to solve the above problems. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a spiral conveyor belt device, which solves the problems mentioned in the background art.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a spiral conveyor belt device, including a device housing, and a conveying structure is provided inside the device housing;
[0007] The conveying structure includes a drive motor, a shaft tube body, and a cleaning structure. The drive motor is fixedly installed at the left end of the equipment housing, and the output end of the drive motor extends into the interior of the equipment housing and is fixedly connected to the shaft tube body. The cleaning structure for cleaning the interior of the equipment housing is located inside the shaft tube body.
[0008] Furthermore, the conveying structure also includes a spiral blade, the inner side of which is fixedly installed on the outer wall of the shaft tube body. A scraper is fixedly connected to the outer wall of the spiral blade. A connecting shaft tube is fixedly connected to the right end of the shaft tube body. The outer wall of the connecting shaft tube is rotatably connected to the inside of the right end of the equipment housing through a bearing. A sealing groove is provided on the outer wall of the shaft tube body. There are several sealing grooves. A through hole is provided inside the shaft tube body at each of the sealing grooves.
[0009] Furthermore, the cleaning structure includes a fixed tube, the left end of which is fixedly installed on the left end of the inner wall of the shaft tube body. A telescopic tube is fixedly connected to the outer wall of the fixed tube. There are several telescopic tubes, and a conveying tube is fixedly connected to the top end of each telescopic tube. A nozzle is fixedly connected to the top end of the conveying tube. A T-shaped seal is fixedly installed on the outer wall of the nozzle. A magnetic component is fixedly installed on the outer wall of the conveying tube. A resistance spring is movably installed on the upper surface of the magnetic component on the outer wall of the conveying tube. An installation tube is fixedly installed on the outer wall of the fixed tube on the outer wall of the telescopic tube. An electromagnet is fixedly installed at the top end of the installation tube below the magnetic component.
[0010] Furthermore, the cleaning structure also includes an L-shaped tube, the left end of which extends into the interior of the connecting shaft tube and is connected to a rotary joint fixed at the right end of the fixed tube. A water pump is fixedly connected to the bottom end of the L-shaped tube, and a water tank is fixedly connected to the interior of the water pump through an input end. The outer wall of the water tank is fixedly installed on the outer wall of the right end of the equipment housing.
[0011] Furthermore, a feed pipe is fixedly connected to the right outer wall of the equipment housing, a programmable controller is fixedly installed on the right end of the equipment housing, and a discharge pipe is fixedly connected to the left outer wall of the equipment housing.
[0012] Furthermore, the combined cross-sectional shape of the sealing groove and the through hole is T-shaped, the outer wall of the T-shaped seal is sealed to the inside of the sealing groove, and the outer wall of the nozzle is located inside the through hole.
[0013] Furthermore, the programmable controller is electrically connected to the water pump, the programmable controller is electrically connected to the electromagnet, and the programmable controller is electrically connected to the drive motor.
[0014] The beneficial effects of this utility model are:
[0015] 1. In this spiral conveyor belt device, through the setting of the cleaning structure, the electromagnet is in a de-energized state when conveying materials. The magnetic component, T-shaped seal, and nozzle resist the downward force of the spring itself, causing the magnetic component to contact the electromagnet. In this way, the nozzle can move into the through hole, and the bottom end of the T-shaped seal moves into the sealing groove, sealing the sealing groove and the through hole. In the non-cleaning state, the nozzle can be hidden to prevent the nozzle from being exposed on the outer wall of the shaft tube body and causing the nozzle to be blocked by materials.
[0016] 2. When the inner wall of the equipment casing needs to be cleaned, the programmable controller energizes the electromagnet, causing the electromagnet and the magnetic component to repel each other. This repulsive force causes the magnetic component to move the nozzle and T-shaped seal at the top of the conveyor pipe away from the sealing groove and through hole, moving the nozzle to the outer wall of the connecting shaft tube. Then, the programmable controller starts the water pump, which delivers water from the tank to the fixed pipe through the output end and L-shaped pipe. The water in the fixed pipe is then sprayed onto the inner wall of the equipment casing through the nozzle, thus quickly cleaning the material on the inner wall of the equipment casing. Simultaneously, the programmable controller starts the drive motor, which drives the shaft tube body, spiral blades, scraper, and nozzle to rotate through the output end. This causes the scraper and nozzle to scrape and clean the attachments on the spiral blades and the inner wall of the equipment casing, reducing resistance during the conveying process and improving conveying efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please see Figures 1-6 A spiral conveyor belt device includes a housing 1, and a conveying structure 2 is provided inside the housing 1;
[0027] The conveying structure 2 includes a drive motor 21, a shaft tube body 22, and a cleaning structure 27. The drive motor 21 is fixedly installed at the left end of the equipment housing 1. The output end of the drive motor 21 extends into the interior of the equipment housing 1 and is fixedly connected to the shaft tube body 22. The cleaning structure 27, which is used to clean the interior of the equipment housing 1, is located inside the shaft tube body 22.
[0028] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the conveying structure 2 also includes a spiral blade 23. The inner side of the spiral blade 23 is fixedly installed on the outer wall of the shaft tube body 22. A scraper 24 is fixedly connected to the outer wall of the spiral blade 23. A connecting shaft tube 25 is fixedly connected to the right end of the shaft tube body 22. The outer wall of the connecting shaft tube 25 is rotatably connected to the inside of the right end of the equipment housing 1 through a bearing 26. A sealing groove 28 is opened on the outer wall of the shaft tube body 22. There are several sealing grooves 28. A through hole 29 is opened in the interior of the shaft tube body 22 at each sealing groove 28.
[0029] In this embodiment, when the inner wall of the equipment housing 1 needs to be cleaned, the programmable controller 4 energizes the electromagnet 279, causing the electromagnet 279 and the magnetic component 276 to repel each other due to their similar polarities. The repulsive force causes the magnetic component 276 to move the nozzle 274 and the T-shaped seal 275 at the top of the delivery pipe 273 out of the sealing groove 28 and the through hole 29, so that the nozzle 274 moves to the outer wall of the connecting shaft pipe 25. Then, the programmable controller 4 starts the water pump 2711, which pumps water from the water tank 2712 through the output end and the L-shaped pipe 2710. The water is conveyed into the fixed pipe 271, and then sprayed onto the inner wall of the equipment housing 1 through the nozzle 274. This allows for rapid cleaning of the material on the inner wall of the equipment housing 1. At the same time, the drive motor 21 is started by the programmable controller 4. The drive motor 21 drives the shaft tube body 22, the spiral blade 23, the scraper 24, and the nozzle 274 to rotate through the output end. This causes the scraper 24 and the nozzle 274 to scrape and clean the attachments on the spiral blade 23 and the inner wall of the equipment housing 1, reducing resistance during the conveying process and improving conveying efficiency.
[0030] Reference Figures 1-6 As shown, the cleaning structure 27 includes a fixed tube 271. The left end of the fixed tube 271 is fixedly installed on the left end of the inner wall of the shaft tube body 22. The outer wall of the fixed tube 271 is fixedly connected to a telescopic tube 272. There are several telescopic tubes 272. The top end of each telescopic tube 272 is fixedly connected to a conveying tube 273. The top end of the conveying tube 273 is fixedly connected to a nozzle 274. A T-shaped seal 275 is fixedly installed on the outer wall of the nozzle 274. A magnetic component 276 is fixedly installed on the outer wall of the conveying tube 273. A resistance spring 277 is movably installed on the upper surface of the magnetic component 276 on the outer wall of the conveying tube 273. An installation tube 278 is fixedly installed on the outer wall of the fixed tube 271 on the outer wall of the telescopic tube 272. An electromagnet 279 is fixedly installed on the top end of the installation tube 278 below the magnetic component 276.
[0031] In this embodiment, when conveying materials, the electromagnet 279 is de-energized. The magnetic component 276, the T-shaped seal 275, and the nozzle 274 resist the magnetic component 276 downwards by the elastic force of the spring 277, causing the magnetic component 276 to come into contact with the electromagnet 279. This allows the nozzle 274 to move into the through hole 29, and the bottom end of the T-shaped seal 275 moves into the sealing groove 28 for sealing. Without cleaning, the nozzle 274 can be hidden to prevent it from being exposed on the outer wall of the shaft tube body 22, which could cause the nozzle 274 to be blocked by materials.
[0032] Reference Figures 1-6As shown, the cleaning structure 27 also includes an L-shaped tube 2710. The left end of the L-shaped tube 2710 extends into the interior of the connecting shaft tube 25 and is connected to a rotary joint fixed at the right end of the fixed tube 271. The bottom end of the L-shaped tube 2710 is fixedly connected to a water pump 2711. The interior of the water pump 2711 is fixedly connected to a water tank 2712 through an input end. The outer wall of the water tank 2712 is fixedly installed on the right outer wall of the equipment housing 1.
[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a feed pipe 3 is fixedly connected to the right outer wall of the equipment housing 1, a programmable controller 4 is fixedly installed on the right side of the equipment housing 1, and a discharge pipe 5 is fixedly connected to the left outer wall of the equipment housing 1.
[0034] Reference Figures 2-6 As shown, the cross-sectional shape of the sealing groove 28 and the through hole 29 combined is T-shaped. The outer wall of the T-shaped seal 275 is sealed with the interior of the sealing groove 28, and the outer wall of the nozzle 274 is located inside the through hole 29.
[0035] Reference Figures 2-4 As shown, the programmable controller 4 is electrically connected to the water pump 2711, the programmable controller 4 is electrically connected to the electromagnet 279, and the programmable controller 4 is electrically connected to the drive motor 21.
[0036] In this embodiment, the drive motor 21 is a servo motor, and its control terminal is controlled by an external power supply control device through a wiring harness.
[0037] In use, when the inner wall of the equipment housing 1 needs to be cleaned, the programmable controller 4 energizes the electromagnet 279, causing the electromagnet 279 and the magnetic component 276 to repel each other. The repulsive force causes the magnetic component 276 to move the nozzle 274 and the T-shaped seal 275 at the top of the conveying pipe 273 out of the sealing groove 28 and the through hole 29, so that the nozzle 274 moves to the outer wall of the connecting shaft pipe 25. Then, the programmable controller 4 starts the water pump 2711, which delivers water from the water tank 2712 to the fixed pipe 271 through the output end and the L-shaped pipe 2710. The water in the fixed pipe 271 is then sprayed onto the inner wall of the equipment housing 1 through the nozzle 274, thus quickly cleaning the material on the inner wall of the equipment housing 1. At the same time, the programmable controller 4 starts the drive motor 21, which drives the... The rotation of the shaft tube body 22, spiral blades 23, scraper 24, and nozzle 274 causes the scraper 24 and nozzle 274 to scrape and clean the deposits on the spiral blades 23 and the inner wall of the equipment housing 1, reducing resistance during the conveying process and improving conveying efficiency. When the equipment is conveying materials, the electromagnet 279 is de-energized. The magnetic component 276, T-shaped seal 275, and nozzle 274 resist the downward force of the magnetic component 276 by the elastic force of the spring 277, so that the magnetic component 276 comes into contact with the electromagnet 279. In this way, the nozzle 274 can move into the through hole 29, and the bottom end of the T-shaped seal 275 moves into the sealing groove 28 for sealing. When not cleaning, the nozzle 274 can be hidden to prevent the nozzle 274 from being exposed on the outer wall of the shaft tube body 22 and causing the nozzle 274 to be blocked by materials.
