Description

Technical Field

[0001] This invention relates to the field of high-viscosity organic slurry processing technology, specifically to a screw conveyor suitable for high-viscosity organic slurries. Background Technology

[0002] In water supply and drainage engineering, environmental protection engineering construction, and the treatment and recycling of sludge and solid waste, it is often necessary to treat organic waste or sludge. After dewatering, organic waste or sewage forms a highly viscous organic slurry. In further processing, the sludge of the highly viscous organic slurry needs to be transported by a screw conveyor.

[0003] For example, Chinese patent CN211768369U discloses an organic waste screw conveyor, including a worktable. Support legs are fixedly installed around the bottom of the worktable, and anti-slip blocks are fixedly installed at the bottom of the support legs. A conveying shaft is fixedly installed on the top of the worktable, and a protective box is fixedly installed on the top of the worktable and to the left of the conveying shaft. This organic waste screw conveyor, equipped with a feed hopper and a motor, works by starting the motor and directly feeding organic waste into the feed hopper. The organic waste then enters the transmission trough through the guide pipe and the feed hopper. The motor's output shaft then drives the screw block to rotate via a transmission rod, thus realizing the conveying of organic waste.

[0004] Chinese Patent CN119160614B discloses a shaftless screw conveyor for sludge treatment and regeneration of ceramsite, relating to the field of sludge treatment technology. The invention includes a housing and a scraping assembly. A motor is fixed to one side of the housing, and the motor's output shaft is connected to a spiral blade. The scraping assembly is located on the outer side of one end of the spiral blade. When cleaning the shaftless spiral blade is required, the invention simply starts the motor, causing the spiral blade to rotate. Since the first and second scrapers are respectively attached to both sides of the spiral blade, the surface of the spiral blade can be scraped and cleaned. The connecting column also blocks the gap formed between the first and second scrapers, preventing residue from passing through. Simultaneously, the height of the top plate is positioned using a sliding block, slide rail, connecting plate, and adjusting assembly.

[0005] Based on existing solutions and actual production and processing applications, existing screw conveyors suitable for high-viscosity organic slurries are inconvenient for quickly cleaning the front and rear sides of the shaftless screw. During the cleaning process, it is also inconvenient to clean the wastewater filtration structure while cleaning the discharge pipe. Therefore, we propose a screw conveyor suitable for high-viscosity organic slurries to solve the problems mentioned above. Summary of the Invention

[0022] By adopting the above technical solution, the fourth motor drives the lifting plate to rise and fall through the lead screw, thereby driving the strip plate to rise and fall, agitating the high-viscosity material, which can improve the feeding speed of the high-viscosity material.

[0023] As a preferred embodiment of the present invention, the bottom end of the toothed ring is rotatably mounted on the lifting plate.

[0024] By adopting the above technical solution, the lifting plate can stably support the gear ring.

[0025] As a preferred embodiment of the present invention, a limit rod passes through the right end of the lifting plate.

[0026] By adopting the above technical solution, the lifting plate is limited and supported by the limiting rod, so as to prevent the lifting plate from tilting and from rotating with the lead screw.

[0028] 1. The forward and backward moving assembly, composed of a second motor, a gear plate, a moving plate, a rack, and rollers, can control the relative position of the cleaning assembly and the shaftless screw. By changing the position of the internal side plate and the cleaning plate of the cleaning assembly, the front and rear sides of the shaftless screw are cleaned. During the rotation of the shaftless screw, the cleaning plate scrapes off the material adhering to the shaftless screw, and the rinsing nozzle sprays water onto the shaftless screw and the inner wall of the conveying housing. Through the cooperation of the forward and backward moving assembly, the cleaning assembly, and the rinsing nozzle, the front and rear sides of the shaftless screw can be cleaned quickly.

[0029] 2. During the conveying of high-viscosity organic slurry, a baffle is installed at the top of the conveying shell.

Detailed Implementation

[0044] 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, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Existing screw conveyors suitable for high-viscosity organic slurries are inconvenient for quick cleaning of the front and rear sides of the shaftless screw 18. During the cleaning process, it is inconvenient to clean the wastewater filtration structure at the same time as cleaning the discharge pipe 19. In order to solve this technical problem, the following technical content is disclosed in this embodiment.

[0046] Please see Figures 1-10A screw conveyor suitable for high-viscosity organic slurry includes a conveying shell 1, a top cover 2, a feed hopper 3, a first motor 4, a scraper 5, a second motor 6, a gear disc 7, a moving plate 8, a rack 9, a roller 10, a third motor 11, an installation roller 12, a side plate 13, a cleaning plate 14, a flushing nozzle 15, a baffle 16, a drive assembly 17, a shaftless screw rod 18, a discharge pipe 19, a support plate 20, a fourth motor 21, a lead screw 22, a lifting plate 23, a fifth motor 24, a gear 25, a gear ring 26, a strip plate 27, a vertical plate 28, a cleaning brush 29, a wastewater treatment box 30, and a wastewater filter plate 31. The conveying shell 1, top cover 2, feed hopper 3, scraper 5, moving plate 8, installation roller 12, side plate 13, baffle 16, shaftless screw rod 18, discharge pipe 19, lead screw 22, wastewater treatment box 30, and wastewater filter plate 31 are all made of corrosion-resistant materials.

[0047] The screw conveyor is equipped with an editable controller. After power-on, the PLC performs a system self-test, checking whether the first motor 4 to the fifth motor 24 in the equipment are ready (inverter status, temperature, current), checking the position sensors in the equipment (moving plate position, lifting plate position, cleaning plate angle), and checking the safety devices (emergency stop button, protective door, overload protection). After initialization is completed, the control interface displays "System ready".

[0048] Automatic conveying mode is activated when baffle 16 is correctly engaged and installed, shaftless screw rod 18 is in the initial position, and there are no fault alarms.

[0049] During cleaning and maintenance, the process of "positioning → cleaning → resetting" is strictly followed. The second motor 6 and the third motor 11 work together to achieve comprehensive cleaning of the front and rear sides of the shaftless screw rod 18. The fourth motor 21 and the fifth motor 24 simultaneously achieve integrated cleaning of the discharge pipe and the filter plate. All motors are equipped with overload, overheat, and overcurrent protection. Key actions are interlocked and interlocked to ensure the safety of personnel and equipment. Fully automatic control is achieved through PLC, supporting remote monitoring and fault early warning. It can be integrated with the factory DCS or MES system.

[0050] like Figure 1 , Figure 5 , Figure 8 and Figure 9 As shown, a top cover 2 is installed on the top of the conveying housing 1, and a feeding hopper 3 is installed on the front end of the top cover 2. A first scraping assembly is installed on the feeding hopper 3. The first scraping assembly includes a first motor 4 and a scraper 5. The first motor 4 is installed on the outside of the feeding hopper 3 through a rod. The output end of the first motor 4 is fixed to the scraper 5 through a rotating rod. The outer side of the scraper 5 is in contact with the inner wall of the feeding hopper 3. The first motor 4 in the first scraping assembly drives the scraper 5 to rotate. The rotation of the scraper 5 can clean the inner wall of the feeding hopper 3 and prevent the material from sticking to the inner wall of the feeding hopper 3.

[0051] like Figure 1 , Figure 6 and Figure 7 As shown, a forward and backward moving assembly is provided behind the feed hopper 3. The forward and backward moving assembly includes a second motor 6, a gear plate 7, a moving plate 8, a rack 9, and rollers 10. The second motor 6 is fixed above the top cover 2 by a rod. The output end of the second motor 6 is fixed to the gear plate 7. The moving plate 8 is provided on the inner side of the top cover 2. The rack 9 is fixed on the upper surface of the moving plate 8. The gear plate 7 and the rack 9 are meshed and connected. Rollers 10 are installed at both ends of the moving plate 8. Slide grooves are opened at both ends of the top cover 2. The rollers 10 are located in the slide grooves of the top cover 2. The second motor 6 drives the rack 9 to move back and forth through the gear plate 7, thereby moving the moving plate 8 back and forth, and thus controlling the position of the cleaning assembly on the moving plate 8. When the moving plate 8 moves back and forth, the rollers 10 roll back and forth in the slide grooves to reduce friction.

[0052] A cleaning component is installed at the bottom of the front and rear moving assembly. The cleaning component includes a third motor 11, a mounting roller 12, a side plate 13, and a cleaning plate 14. The third motor 11 is fixed to the front side of the moving plate 8. The mounting roller 12 is fixed to the output end of the third motor 11. The side plate 13 is fixed at equal intervals on the outer side of the mounting roller 12. The cleaning plate 14 is pasted to the outer end of the side plate 13. The third motor 11 drives the mounting roller 12, the side plate 13, and the cleaning plate 14 to rotate, thereby controlling the position of the side plate 13 and the cleaning plate 14.

[0053] The top cover 2 has flushing nozzles 15 installed at equal intervals on the left side of the interior. A baffle 16 is provided below the top cover 2. The baffle 16 is connected to the conveying housing 1 by a snap-fit ​​connection. The baffle 16 and the conveying housing 1 are disassembled and assembled by the snap-fit ​​connection.

[0054] A drive assembly 17 is provided on the front side of the conveying housing 1. A shaftless screw rod 18 is fixed to the output end of the drive assembly 17. A discharge pipe 19 is provided at the rear end of the conveying housing 1. A second scraping assembly is provided on the outside of the discharge pipe 19. A sewage treatment box 30 is provided at the rear of the conveying housing 1. A sewage filter plate 31 is installed inside the sewage treatment box 30. The second scraping assembly includes a support plate 20, a fourth motor 21, a lead screw 22, a lifting plate 23, a fifth motor 24, a gear 25, a gear ring 26, a strip plate 27, a vertical plate 28, and a cleaning brush 29. The fourth motor 21 is provided above the support plate 20. A lead screw 22 is fixed to the output end of the fourth motor 21. The lead screw 22 is threaded to the lifting plate 23. The fifth motor 24 is installed on the lifting plate 23. The output end of the fifth motor 24 is fixed with a gear 25. The right end of the gear 25 is meshed with a gear ring 26. A strip plate 27 is installed on the inner side of the gear ring 26. A vertical plate 28 is threaded to the bottom end of the strip plate 27. A cleaning brush 29 is fixed to the bottom end of the vertical plate 28. The bottom end of the gear ring 26 is rotatably mounted on the lifting plate 23. A limit rod passes through the right end of the lifting plate 23. The fourth motor 21 drives the lifting plate 23 to rise and fall through the lead screw 22, thereby driving the strip plate 27 to rise and fall. This agitates the highly viscous material and can improve the feeding speed of the highly viscous material. The lifting plate 23 can stably support the gear ring 26. The limit rod limits and supports the lifting plate 23 to prevent it from tilting and to prevent it from rotating with the lead screw 22.

[0055] During the conveying process of high-viscosity organic slurry, when feeding, since the top cover 2 has a round hole inside, the round hole at the front end of the top cover 2 is aligned with the discharge port of the feed hopper 3. The high-viscosity organic slurry is fed into the feed hopper 3 and then passes through the round hole of the top cover 2 into the interior of the conveying shell 1.

[0056] The drive assembly 17 drives the shaftless screw 18 to rotate, conveying the high-viscosity organic slurry to the discharge pipe 19. The high-viscosity organic slurry then flows out of the discharge pipe 19. During the discharge process, the fifth motor 24 drives the gear 25 to rotate, thereby rotating the gear ring 26 that meshes with the gear 25. In turn, the strip 27 fixed inside the gear ring 26 rotates. The strip 27 rotates on the inner wall of the discharge pipe 19, cleaning the inner wall of the discharge pipe 19 and achieving rapid discharge. The fourth motor 21 drives the lead screw 22 to rotate, and the lifting plate 23 threadedly connected to the lead screw 22 rises and falls, causing the strip 27 to rise and fall inside the discharge pipe 19, agitating the high-viscosity organic slurry and increasing the discharge speed. The limiting rod penetrating the right end of the lifting plate 23 limits the movement trajectory of the lifting plate 23 and can support the lifting plate 23.

[0057] During the feeding process, the first scraping component can clean the feed hopper 3. Under the action of the first motor 4, the scraper 5 rotates. The rotation of the scraper 5 scrapes away the material on the inner wall of the feed hopper 3, improving the feeding effect and preventing material from remaining in the feed hopper 3.

[0058] When it is necessary to clean the shaftless screw 18, hold the left end of the baffle 16 and move the baffle 16 to the left so that the baffle 16 leaves the conveyor housing 1, exposing the flushing nozzle 15, the mounting roller 12, the side plate 13 and the cleaning plate 14.

[0059] The position of the cleaning plate 14 is adjusted by the forward and backward moving assembly. The second motor 6 drives the gear plate 7 to rotate. The rack 9, which is meshed with the gear plate 7, moves forward and backward, thereby moving the moving plate 8, which is fixedly connected to the rack 9, forward and backward. When the moving plate 8 moves forward and backward, the roller 10 rolls back and forth in the groove of the top cover 2 to reduce friction. The position of the side plate 13 and the cleaning plate 14 is adjusted by the forward and backward movement of the moving plate 8. First, the cleaning plate 14 is made to fit against the front side of the top end of the shaftless spiral rod 18.

[0060] Under the action of the third motor 11, the mounting roller 12 is rotated, so that the side plate 13 and the cleaning plate 14 are rotated out from the inside of the top cover 2. The outer side of the cleaning plate 14 is in contact with the outer side of the top end of the shaftless spiral rod 18. When the drive assembly 17 drives the shaftless spiral rod 18 to rotate, the cleaning plate 14 moves back and forth, and the cleaning plate 14 can scrape off the material adhering to the shaftless spiral rod 18.

[0061] After cleaning the front side of the shaftless spiral rod 18, the mounting roller 12, side plate 13 and cleaning plate 14 are retracted under the action of the third motor 11. Then, the position of the cleaning plate 14 is moved by the front and rear moving assembly, and the side plate 13 and cleaning plate 14 are rotated out so that each set of cleaning plates 14 can fit against the rear side of the top of the shaftless spiral rod 18, and can clean the other side of the shaftless spiral rod 18. The cleaning plate 14 is made of deformable sponge or wire cloth.

[0062] like Figure 5 As shown, a pipe is installed parallel to the left side of the top cover 2. The pipe is connected to the flushing nozzle 15 through a hose. The pipe is connected to an external water source to supply water to the flushing nozzle 15. While the shaftless spiral rod 18 is cleaned by the cleaning plate 14, water is sprayed onto the shaftless spiral rod 18 and the inner wall of the conveying housing 1 through the flushing nozzle 15 to flush the shaftless spiral rod 18 and the inner wall of the conveying housing 1.

[0063] Before cleaning, manually place the vertical plate 28 and cleaning brush 29 into the sewage treatment box 30. The vertical plate 28 and cleaning brush 29 are located on the sewage filter plate 31. Push the sewage treatment box 30 so that the center of the sewage treatment box 30 coincides with the center of the discharge pipe 19. Hold the vertical plate 28 so that the vertical plate 28 is threadedly connected to the bottom end of the strip plate 27. The fifth motor 24 drives the strip plate 27, vertical plate 28 and cleaning brush 29 to rotate through the gear 25 and gear ring 26, thereby cleaning the filter surface of the sewage filter plate 31. The sewage during cleaning flows into the sewage treatment box 30 and is filtered through the sewage filter plate 31. The filtered water flows out from the pipe at the right end of the sewage treatment box 30. The material remains on the sewage filter plate 31. The cleaning brush 29 is used to prevent the material from clogging the sewage filter plate 31.
