Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and specifically to a sludge shaftless screw conveyor for sludge disposal and regeneration of ceramsite. Background Technique

[0002] The process of sludge regeneration of ceramsite mainly involves high-temperature calcination of sludge. This process is usually carried out in a rotary kiln. During the calcination process, organic matter and moisture in the sludge are removed. At the same time, by controlling the temperature and time, the sludge is transformed into ceramsite with specific properties. This regenerated ceramsite is not only an environmentally friendly and lightweight building material, but also due to its unique physical and chemical properties, it is widely used in multiple fields. In the process of sludge regeneration of ceramsite, a shaftless screw conveyor is needed to transport the sludge.

[0003] For example, the patent with the publication number CN211225186U discloses a sludge dewatering directly driven shaftless screw conveyor. This patent removes the gearbox, and the screw conveyor and the driving device are directly driven and connected, thereby reducing the use cost, having higher transmission efficiency, being more energy-saving, and being more convenient for installation and maintenance. However, in the process of maintenance and cleaning of this type of shaftless screw conveyor, it is not convenient to automatically clean the sludge on the blades, resulting in time-consuming and laborious maintenance.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sludge shaftless screw conveyor for sludge disposal and regeneration of ceramsite is proposed. Summary of the Invention

[0016] The present invention provides a sludge shaftless screw conveyor for sludge disposal and recycled ceramsite, having the following beneficial effects:

[0017] 1. When the shaftless screw blade needs to be cleaned in the present invention, only the motor needs to be started to make the screw blade rotate. At this time, since the first scraper and the second scraper are respectively attached to both sides of the screw blade, the surface of the screw blade can be scraped and cleaned. Moreover, the connecting column can also block the gap formed between the first scraper and the second scraper to prevent residues from passing through. At the same time, the height of the top plate is positioned by using the sliding seat, the sliding rail, the connecting plate and the adjusting assembly, so as to prevent the first scraper from sliding vertically. Therefore, when the screw blade rotates, it will also push the first scraper to move, so as to comprehensively clean the outside of the screw blade. And there are two groups of first scrapers, which is beneficial to improving the cleaning effect on the surface of the screw blade.

[0018] 2. After cleaning in the present invention, the sliding seat will move to the other end along the sliding rail. At this time, only need to hold the connecting plate by hand and press the pressing plate with the thumb, so that the sliding columns at both ends can squeeze the driving block, which drives the positioning pin to separate from the positioning hole at the lower part of the limiting column, so as to quickly release the restriction between the connecting plate and the limiting column. After lifting the top plate, release the thumb. At this time, the spring will drive the pressing plate to move up and reset, so that the positioning pin is inserted into the positioning hole at the upper part of the limiting column, and the first scraper moves out of the housing. At this time, the top plate can be conveniently moved horizontally through the sliding rail and the sliding seat, and the normal conveying work of the screw blade will not be affected in this state.

[0019] 3. When the spiral blade drives the first scraper to move, the present invention can also use an external pump to transport cleaning water through the water inlet hose into the diversion cover. At this time, the water flow will push the internal drive blades, so that the drive shaft can drive the driving gear to rotate, causing the driven gear to drive the bristles outside the cleaning shaft to brush and clean the outside of the spiral blade. And the number of cleaning shafts is set to two, which can clean both sides of the spiral blade, making the cleaning more comprehensive. At the same time, the water flow flowing out from the other end of the diversion cover will enter the fixed cover through the water delivery pipe, three-way valve, and connecting pipe, then flow into the inside of the cleaning shaft and spray out from the spray holes on the outside, so that flushing can also be carried out during cleaning, further enhancing the cleaning effect. And when the water accumulation between the two first scrapers is too much, it will be discharged through the one-way valve.

[0020] 4. When the sliding seat moves to the end of the slide rail, the drive plate on the three-way valve will contact the strong magnet and be squeezed and rotated under the limit of the fixed plate, so that the water flow direction inside the three-way valve can be automatically switched. Therefore, when the spiral blade is separated from the first scraper, the water flow inside the water delivery pipe will flow into the shunt hose through the three-way valve and spray out from the nozzles at the bottom of the spray pipe, so as to flush the surfaces of the first scraper and the second scraper, reducing the sludge attachment on the scraper surface and facilitating subsequent cleaning. At the same time, the driving gear will also drive the synchronous gear to rotate, causing the driving column to push and pull the limiting plate reciprocally, thereby driving the connecting rod to move synchronously, and the adjusting block will drive the spray pipe to rotate reciprocally through the rotating plate, so that the flushing direction can be automatically changed, which is beneficial to increasing the flushing range of the scraper. And during the subsequent upward movement of the top plate, the fixed plate will also be driven to move upward. At this time, the sliding rod can slide in the limiting seat. When the sliding seat is moved towards the motor, the strong magnet will adsorb the iron driving plate to reset it, so that there is no need to manually switch the three-way valve, saving the operation steps and being more convenient.

Slide rails 401 are arranged on both sides of the housing 1, and slide seats 402 are slidably connected to the outer sides of the slide rails 401. Limit posts 403 are fixed at both ends of the top of the slide seat 402, and connecting plates 404 are slidably connected to the outer sides of the lower ends of the limit posts 403. A top plate 405 is fixed on one side of the connecting plate 404, and first scrapers 406 are arranged at both ends of the bottom of the top plate 405. A second scraper 407 is connected to one side of the first scraper 406, and a connecting column 408 is fixed at the bottom of the second scraper 407, and a check valve 409 is arranged inside the connecting column 408.

[0030] Please refer to Figures 1 to 4 Figures 1 to 4 , an adjusting assembly 5 is arranged inside the connecting plate 404. The adjusting assembly 5 includes a damper 501, a spring 502, a pressing plate 503 and a sliding column 504. The damper 501 is arranged at the center inside the connecting plate 404, and the spring 502 is sleeved outside the damper 501. The top of the spring 502 is connected to the pressing plate 503, and the pressing plate 503 is in an n shape. And a sliding column 504 is fixed inside the lower end of the pressing plate 503. The adjusting assembly 5 further includes a driving block 505, a positioning pin 506 and a positioning hole 507. The driving block 505 is slidably connected to the outer side of the end of the sliding column 504, and the positioning pins 506 are symmetrically arranged on one side of the driving block 505, and the positioning pins 506 are slidably connected to the connecting plate 404. Positioning holes 507 are opened at the upper and lower ends on one side of the limiting column 403;

[0031]

[0031] The specific operation is as follows. When it is necessary to deliver sludge, first hold the connecting plate 404 by hand and press the pressing plate 503 with the thumb, so that the sliding columns 504 at both ends can squeeze the driving block 505, causing it to drive the positioning pin 506 to separate from the positioning hole 507 at the lower part of the limiting column 403, thereby quickly releasing the restriction between the connecting plate 404 and the limiting column 403. After moving the top plate 405 upward and releasing the thumb, at this time the spring 502 will drive the pressing plate 503 to move upward and reset, so that the positioning pin 506 is inserted into the positioning hole 507 at the upper part of the limiting column 403, causing the first scraper 406 to move out of the housing 1. Then start the motor 2 to drive the spiral blade 3 to rotate to convey the sludge. And when it is necessary to maintain and clean the shaftless screw conveyor, first use the sliding seat 402 or the slide rail 401 to conveniently move it to one end of the spiral blade 3. Similarly, then use the adjusting assembly 5 to move and fix the top plate 405 outside the lower end of the limiting column 403. At this time, the height of the top plate 405 can be positioned. At the same time, the first scraper 406 and the second scraper 407 will respectively fit on both sides of the spiral blade 3. Then start the motor 2, so that the spiral blade 3 rotates, which will push the first scraper 406 to move under the guidance of the slide rail 401 and the sliding seat 402. Therefore, the surface of the spiral blade 3 can be scraped and cleaned. And the connecting column 408 can also block the gap formed between the first scraper 406 and the second scraper 407 to prevent residues from passing through. And there are two groups of the first scrapers 406, which is beneficial to improving the cleaning effect on the surface of the spiral blade 3.

The flushing assembly 6 includes a fixed cover 601, a diversion cover 602, a water inlet hose 603, a driving blade 604, a transmission shaft 605 and a driving gear 606. The fixed cover 601 is arranged on the top of the top plate 405, and a diversion cover 602 is arranged on the top of the fixed cover 601. One side of the diversion cover 602 is connected with the water inlet hose 603, and a driving blade 604 is slidably connected inside the diversion cover 602. One side of the driving blade 604 is fixed with a transmission shaft 605, and a driving gear 606 is arranged on the outer side of the lower end of the transmission shaft 605. The flushing assembly 6 further includes a driven gear 607, a cleaning shaft 608, bristles 609 and water spraying holes 610. The two sides of the driving gear 606 are engaged with the driven gear 607, and a cleaning shaft 608 is fixed inside the driven gear 607. The cleaning shaft 608 is hollow and is rotatably connected with the top plate 405. Bristles 609 are fixed on the outer side of the lower end of the cleaning shaft 608, and water spraying holes 610 are formed on the outer side of the lower end of the cleaning shaft 608. The flushing assembly 6 further includes a water delivery pipe 611, a three-way valve 612 and a connecting pipe 613. The other side of the diversion cover 602 is connected with the water delivery pipe 611, and the end of the water delivery pipe 611 is connected with the three-way valve 612. One side of the three-way valve 612 is connected with the connecting pipe 613, and the inside of the connecting pipe 613 is communicated with the inside of the fixed cover 601. One end of the slide rail 401 is fixed with a limit seat 7, and a slide bar 8 is slidably connected to one side of the limit seat 7. A fixing plate 9 is arranged on the top of the slide bar 8, and a strong magnet 10 is connected to one end of the fixing plate 9. A driving plate 11 is arranged at the upper end of the three-way valve 612. A rotating assembly 12 is connected to one side of the fixed cover 601. The rotating assembly 12 includes a synchronous gear 1201, a driving column 1202 and a limit plate 1203. The synchronous gear 1201 is rotatably connected to one end of the bottom of the fixed cover 601 and is engaged with the driving gear 606. The driving column 1202 is fixed to the bottom of the synchronous gear 1201, and the limit plate 1203 is slidably connected to the outer side of the driving column 1202. The rotating assembly 12 further includes a connecting rod 1204, an adjusting block 1205 and a rotating plate 1206. The connecting rod 1204 is fixed to the bottom of the limit plate 1203 and is slidably connected with the top plate 405. Adjusting blocks 1205 are arranged at the bottoms of both ends of the connecting rod 1204, and the rotating plate 1206 is slidably connected to one side of the adjusting block 1205. The rotating assembly 12 further includes a water spraying pipe 1207 and a shunt hose 1208. The water spraying pipe 1207 is fixed to the bottom of the rotating plate 1206 and is rotatably connected with the top plate 405. One end of the top of the water spraying pipe 1207 is connected with the shunt hose 1208, and the shunt hose 1208 is fixed to the three-way valve 612;

[0033] The specific operation is as follows. During the scraping and cleaning process, starting the external pump body will transport the cleaning water through the water inlet hose 603 to the flow guide cover 602. At this time, the water flow will push the internal drive blades 604, so that the drive shaft 605 can drive the driving gear 606 to rotate, enabling the driven gear 607 to drive the brush hairs 609 on the outer side of the cleaning shaft 608 to brush and clean the outer side of the spiral blade 3. And the number of cleaning shafts 608 is set to two, which can clean both sides of the spiral blade 3, making the cleaning more comprehensive. At the same time, the water flow flowing out from the other end of the flow guide cover 602 will enter the fixed cover 601 through the water delivery pipe 611, the three-way valve 612, and the connecting pipe 613, then flow into the inside of the cleaning shaft 608 and spray out from the spray holes 610 on the outer side, so that flushing can be carried out during cleaning, further enhancing the cleaning effect. And when the accumulated water between the two first scrapers 406 is too much, it will be discharged through the one-way valve 409. And when the slide seat 402 moves to the end of the slide rail 401, the drive plate 11 on the three-way valve 612 will contact the strong magnet 10 and be extruded and rotated under the limitation of the fixed plate 9, so that the water flow direction inside the three-way valve 612 can be automatically switched. Therefore, when the spiral blade 3 is separated from the first scraper 406, the water flow inside the water delivery pipe 611 will flow into the shunt hose 1208 through the three-way valve 612 and spray out from the nozzles at the bottom of the spray pipe 1207, so as to flush the surfaces of the first scraper 406 and the second scraper 407, reducing the sludge adhesion on the scraper surface, which is beneficial to improving the convenience during subsequent cleaning. At the same time, the driving gear 606 will also drive the synchronous gear 1201 to rotate, so that the driving column 1202 reciprocally pushes and pulls the limiting plate 1203, thereby driving the connecting rod 1204 to move synchronously. The adjusting block 1205 will drive the spray pipe 1207 to reciprocally rotate through the rotating plate 1206, and the flushing direction can be automatically changed during flushing, increasing the flushing range. And after cleaning the scraper, similarly, the first scraper 406 is moved out of the housing 1 through the adjusting assembly 5. And during the upward movement of the top plate 405, the fixed plate 9 will also be driven to move upward. At this time, the sliding rod 8 can slide in the limiting seat 7. When the slide seat 402 is moved towards the motor 2, the strong magnet 10 will adsorb the iron drive plate 11 to reset it, so that there is no need to manually switch the three-way valve 612, saving the operation steps and being more labor-saving and convenient.

[0034] In summary, for the sludge shaftless screw conveyor for disposing and regenerating ceramsite with the above structure, during use, first, when using the shaftless screw conveyor to convey sludge, first hold the connecting plate 404 by hand and press the pressing plate 503 with the thumb, so that the sliding columns 504 at both ends can squeeze the driving block 505, driving the positioning pin 506 to separate from the positioning hole 507 at the lower part of the limiting column 403, thus quickly releasing the restriction between the connecting plate 404 and the limiting column 403. After lifting the top plate 405 and releasing the thumb, the spring 502 will drive the pressing plate 503 to move upward and reset at this time, so that the positioning pin 506 is inserted into the positioning hole 507 at the upper part of the limiting column 403, and the first scraper 406 moves out of the housing 1. Secondly, start the motor 2 to drive the spiral blade 3 to rotate, so as to convey the sludge inside one end of the housing 1. Then, when it is necessary to maintain and clean the shaftless screw conveyor, first use the sliding seat 402 or the slide rail 401 to conveniently move it to one end of the spiral blade 3. Similarly, use the adjusting component 5 to move and fix the top plate 405 outside the lower end of the limiting column 403. At this time, the height of the top plate 405 can be positioned. At the same time, the first scraper 406 and the second scraper 407 will respectively fit on both sides of the spiral blade 3. Then start the motor 2, and when the spiral blade 3 rotates, it will push the first scraper 406 to move under the guidance of the slide rail 401 and the sliding seat 402, so that the surface of the spiral blade 3 can be scraped and cleaned. And the connecting column 408 can also block the gap formed between the first scraper 406 and the second scraper 407. Then, use an external pump to convey the cleaning water through the water inlet hose 603 into the flow guide cover 602. At this time, the water flow will push the internal driving blade 604, so that the driving shaft 605 can drive the driving gear 606 to rotate, making the driven gear 607 drive the bristles 609 outside the cleaning shaft 608 to brush and clean the outside of the spiral blade 3. At the same time, the water flow flowing out from the other end of the flow guide cover 602 will enter the fixed cover 601 through the water delivery pipe 611, the three-way valve 612, and the connecting pipe 613, and then flow into the inside of the cleaning shaft 608 and spray out from the spray holes 610 on the outside, so that flushing can be carried out during cleaning. And when the accumulated water between the two first scrapers 406 is too much, it will be discharged through the one-way valve 409. After that, when the sliding seat 402 moves to the end of the slide rail 401, the driving plate 11 on the three-way valve 612 will contact the strong magnet 10 and be squeezed and rotated under the limit of the fixing plate 9, so that the water flow direction inside the three-way valve 612 can be automatically switched. Therefore, when the spiral blade 3 is separated from the first scraper 406, the water flow inside the water delivery pipe 611 will flow into the shunt hose 1208 through the three-way valve 612 and spray out from the nozzles at the bottom of the spray pipe 1207, so as to wash the surfaces of the first scraper 406 and the second scraper 407. At the same time, the driving gear 606 will also drive the synchronous gear 1201 to rotate, so that the driving column 1202 reciprocally pushes and pulls the limiting plate 1203, driving the connecting rod 1204 to move synchronously.The adjusting block 1205 will drive the water spraying pipe 1207 to rotate reciprocally through the rotating plate 1206, so as to increase the range during flushing. Finally, after cleaning the scraping plate, similarly, the first scraping plate 406 is moved out of the housing 1 through the adjusting assembly 5. During the upward movement of the top plate 405, the fixing plate 9 is also driven to move upward. At this time, the sliding rod 8 can slide within the limit seat 7. When the sliding seat 402 is moved towards the motor 2, the strong magnet 10 will adsorb the iron driving plate 11 to reset it, thus eliminating the need for manual switching of the three-way valve 612.
