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

[0016] The present invention provides a sludge shaftless screw conveyor for sludge disposal and regeneration of ceramsite, which has the following beneficial effects: 1. When the shaftless spiral blade needs to be cleaned, the present invention only needs to start the motor to rotate the spiral blade. At this time, since the first scraper and the second scraper are respectively in contact with the two sides of the spiral blade, the surface of the spiral blade can be scraped and cleaned, and the connecting column can also block the gap formed between the first scraper and the second scraper to prevent residue from passing through. At the same time, the height of the top plate is positioned by using the slide seat, the slide rail, the connecting plate and the adjustment component, so as to prevent the first scraper from sliding vertically. Therefore, when the spiral blade rotates, it will also push the first scraper to move, so that it can fully clean the outside of the spiral blade. In addition, two groups of first scrapers are provided, which is beneficial to improve the effect of cleaning the surface of the spiral blade.

[0017] 2. After cleaning, the slide seat of the present invention will move to the other end along the slide rail. At this time, you only need to hold the connecting plate with your hand and press the pressure plate with your thumb to make the slide columns at both ends squeeze the driving blocks, so that the positioning pins can be driven to separate from the positioning holes at the bottom of the limit column, thereby quickly releasing the restriction between the connecting plate and the limit column. After moving the top plate up, release your thumb. At this time, the spring will drive the pressure plate to move up and reset, so that the positioning pins are inserted into the positioning holes at the top of the limit column, so that the first scraper moves out of the shell. At this time, the slide rail and the slide seat can facilitate the horizontal movement of the top plate, and the normal conveying work of the spiral blade will not be hindered in this state.

[0018] 3. In the present invention, when the spiral blade drives the first scraper to move, the external pump body can be used to transport the cleaning water to the guide cover through the water inlet hose. At this time, the water flow will push the internal driving blade, so that the driving gear can be driven to rotate through the transmission shaft, so that the driven gear drives the bristles on the outside of the cleaning shaft to brush and clean the outside of the spiral blade, and there are two cleaning shafts, which can clean both sides of the spiral blade, making the cleaning more comprehensive. At the same time, the water flowing out from the other end of the guide cover will enter the fixed cover through the water supply pipe, the three-way valve, and the connecting pipe, and then flow into the interior of the cleaning shaft and spray out from the water spray hole on the outside, so that flushing can be performed during cleaning, further enhancing the cleaning effect, and when there is too much water between the two first scrapers, it will be discharged through the one-way valve.

[0019] 4. In the present invention, when the slide seat moves to the end of the slide rail, the driving plate on the three-way valve will contact the strong magnet and squeeze and rotate under the limit of the fixed plate, so that the flow direction of the water inside the three-way valve can be automatically switched. Therefore, when the spiral blade is separated from the first scraper, the water inside the water pipe will flow into the diversion hose through the three-way valve and be sprayed out from the nozzle at the bottom of the water spray pipe, so as to wash the surface of the first scraper and the second scraper, reduce the sludge adhesion on the scraper surface, and help to improve the convenience of subsequent cleaning. At the same time, the active gear will also drive the synchronous gear to rotate, so that the driving column reciprocates to push and pull the limit plate, thereby driving the connecting rod to move synchronously, and the adjusting block will drive the water spray pipe to rotate reciprocatingly through the rotating plate, so as to automatically change the direction of flushing, which is beneficial to improve the range of flushing the scraper, and in the subsequent process of moving the top plate up, it will also drive the fixed plate to move up. At this time, the slide rod can slide in the limit seat, and when the slide seat is moved to move it toward the motor, the strong magnet will adsorb the iron drive plate to reset it, so that there is no need to manually switch the three-way valve, saving steps during operation and being more convenient.

During the scraping and cleaning process, the external pump body is started to transport the cleaning water to the guide cover 602 through the water inlet hose 603. At this time, the water flow will push the internal driving blade 604, so that the driving gear 606 can be driven to rotate through the transmission shaft 605, so that the driven gear 607 drives the bristles 609 on the outside of the cleaning shaft 608 to brush and clean the outside of the spiral blade 3. There are two cleaning shafts 608, which can clean both sides of the spiral blade 3, making the cleaning more comprehensive.

The water pipe 611, the three-way valve 612, and the connecting pipe 613 enter the fixed cover 601, and then flow into the interior of the cleaning shaft 608 and spray out from the outer water spray hole 610, so that it can also be flushed during cleaning, further enhancing the cleaning effect, and when there is too much water between the two first scrapers 406, it will also be discharged through the one-way valve 409, and when the slide 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 squeeze and rotate under the limit of the fixed plate 9, so that the water flow inside the three-way valve 612 can be automatically adjusted. The first scraper 406 is switched, so when the spiral blade 3 is separated from the first scraper 406, the water flow in the water pipe 611 will flow into the diversion hose 1208 through the three-way valve 612, and will be sprayed out from the nozzle at the bottom of the water spray pipe 1207, so as to wash the surface of the first scraper 406 and the second scraper 407, reduce the sludge adhesion on the scraper surface, and help to improve the convenience of subsequent cleaning. At the same time, the active gear 606 will also drive the synchronous gear 1201 to rotate, so that the driving column 1202 reciprocates to push and pull the limit plate 1203, thereby driving the connecting rod 1204 to move synchronously, and the adjusting block 1205 will drive the water spray pipe 1207 to rotate back and forth through the rotating plate 1206, which can automatically change the direction of flushing and increase the range of flushing. After cleaning the scraper, the first scraper 406 is moved out of the shell 1 through the adjusting component 5. In the process of the top plate 405 moving up, the fixed plate 9 will also be driven to move up. At this time, the slide rod 8 can slide in the limit seat 7, and when the slide seat 402 is moved toward the motor 2, the strong magnet 10 will absorb the iron drive plate 11 to reset it, thereby eliminating the need for manual switching of the three-way valve 612, saving steps during operation, and being more labor-saving and convenient.

[0025] In summary, when using this shaftless screw conveyor for sludge disposal and regeneration of expanded clay, first, when using the shaftless screw conveyor to transport sludge, first hold the connecting plate 404 with your hand, and press the pressure plate 503 with your thumb, so that the sliding columns 504 at both ends can squeeze the driving block 505, so that it drives the positioning pin 506 to separate from the positioning hole 507 at the bottom of the limiting column 403, thereby quickly releasing the restriction between the connecting plate 404 and the limiting column 403, and after moving the top plate 405 upward, release your thumb, at this time, the spring 502 will drive the pressure plate 503 to move up and reset, so that the positioning pin 506 is inserted into the positioning hole 507 at the top of the limiting column 403, so that the first scraper 406 moves out of the shell 1, and then, start the motor 2 to drive the spiral blade 3 to rotate, The sludge inside one end of the shell 1 is transported. Then, when the shaftless screw conveyor needs to be maintained and cleaned, the slide 402 or the slide rail 401 is first used to move it to one end of the spiral blade 3. Similarly, the adjustment component 5 is used to move and fix the top plate 405 to the outer side of the lower end of the limit column 403. At this time, the height of the top plate 405 can be positioned, and the first scraper 406 and the second scraper 407 will fit with the two sides of the spiral blade 3 respectively. Then, the motor 2 is started to make the spiral blade 3 rotate, which will push the first scraper 406 to move under the guidance of the slide rail 401 and the slide 402. Therefore, the surface of the spiral blade 3 can be scraped and cleaned, and the connecting column 408 can also form a space between the first scraper 406 and the second scraper 407. The gap is blocked, and then, the cleaning water is delivered to the guide cover 602 through the water inlet hose 603 by using the external pump body. At this time, the water flow will push the internal driving blade 604, so that the driving gear 606 can be driven to rotate through the transmission shaft 605, so that the driven gear 607 drives the bristles 609 on the outside of 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 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 outer water spray hole 610, so that it can also be flushed during cleaning. When there is too much water between the two first scrapers 406, it will also pass through the one-way valve 409. After that, when the slide 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 squeeze and rotate under the limit 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 pipe 611 will flow into the diversion hose 1208 through the three-way valve 612 and be sprayed out from the nozzle at the bottom of the water spray pipe 1207, so as to wash the surface of the first scraper 406 and the second scraper 407. At the same time, the active gear 606 will also drive the synchronous gear 1201 to rotate, so that the driving column 1202 pushes and pulls the limit plate 1203 back and forth, thereby driving the connecting rod 1204 to move synchronously.The adjusting block 1205 will drive the water spray pipe 1207 to rotate back and forth through the rotating plate 1206, so as to increase the range of flushing. Finally, after cleaning the scraper, the first scraper 406 is moved out of the housing 1 through the adjusting component 5. In the process of the top plate 405 moving up, the fixed plate 9 is also driven to move up. At this time, the slide bar 8 can slide in the limit seat 7. When the slide seat 402 is moved toward the motor 2, the strong magnet 10 will absorb the iron drive plate 11 to reset it, so that there is no need to manually switch the three-way valve 612.
