Description

Technical Field

[0001] This invention relates to the field of carbon raw block production technology, and more specifically, to a stirring device for roasting and pelletizing carbon raw blocks. Background Technology

[0002] In the production of carbon materials, a large amount of waste material with unqualified particle size or substandard physical properties is generated, including waste coke powder produced during the roasting process. To achieve resource recycling and reduce production costs, an effective treatment method is to use this waste coke powder as the main aggregate, mixed with an appropriate amount of binder and water, and then reprocessed into usable carbon products through stirring, molding, and subsequent roasting. The core of this process lies in using a stirring device to homogenize the waste coke powder, binder, and water to form a well-plasticized mixture, which can then be used to produce green pellets (i.e., spherical carbon green blocks).

[0003] In the process of making carbon raw blocks, coke powder, binder and water are usually mixed in a mixing tank according to a specific ratio to form a homogeneous material, which is then conveyed to a pelletizing machine for molding. However, in this process, because the coke powder and binder are introduced from two separate feed ports or added in batches, uneven distribution and layering can easily occur, thus affecting the uniformity of the mixture.

[0004] For example, the "Raw Material Mixing Device for Carbon Production" disclosed in Chinese Utility Model Patent (Publication No.: CN 213913244 U) states in its specification: This utility model relates to the field of brick processing technology, specifically to a raw material mixing device for carbon production, including a shell, a crossbeam installed in the middle of the upper surface of the shell, a rotating shaft movably installed inside the lower end of the crossbeam, two driving helical gears fixed at intervals on the rotating shaft, each driving helical gear having driven helical gears meshing on both sides, the driven helical gears being fixed to one end of a rotating rod, and the other end of the rotating rod being installed on the inner wall of the shell. This invention uses an active helical gear and a driven helical gear to drive a rotating rod. The lower rotating rod rotates in the forward direction, using a mixing component to transport the raw materials to the center. The upper rotating rod rotates in the reverse direction, using the mixing component to transport the raw materials to both ends. At the same time, the spiral blades can lift the raw materials upward, thereby promoting the circulation of the raw materials during the mixing process. The opposite rotation direction of the stirring rods can create a shearing effect when mixing the raw materials, resulting in more uniform mixing and improved carbon product quality. However, although this patent implements layered mixing of materials used in the production of carbon briquettes, adding different materials separately or in batches before mixing can easily lead to uneven distribution and layered accumulation, thus affecting the mixing effect of the carbon briquettes.

[0005] Therefore, we have made improvements to this and proposed a stirring device for roasting and pelletizing raw carbon blocks. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing methods where coke powder and binder are added separately or in batches, which easily leads to uneven distribution and layering, affecting the uniformity of mixing.

[0016] As a preferred technical solution of this application, an upper ring plate is fixedly connected to the middle of several upper arc plates, and the inner wall of the upper ring plate is fixedly installed in the middle of the outer wall of the auxiliary cylinder.

[0017] As a preferred technical solution of this application, a lower conical ring is fixedly connected below the auxiliary cylinder, and the lower conical ring is located above the side groove.

[0018] As a preferred technical solution of this application, a discharge pipe is fixedly connected to the lower center of the tank body, and a number of support rods are fixedly connected in a circumferentially evenly distributed manner on the lower surface of the tank body, with a pad fixedly connected to the bottom end of the support rod.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. To address the problem in existing technologies where coke powder and binder are added separately or in batches, leading to uneven distribution and layering, thus affecting the uniformity of mixing, a method is proposed that uses a motor to drive a spiral ring plate to rotate in the forward direction. This conveys the powdery material entering the auxiliary cylinder from the side chute upwards to the filter screen plate for secondary filtration. During the conveying process, the material is also stirred and mixed, thus enabling the coke powder and binder to be conveyed and turned upwards. After filtration, the material falls into the tank, ensuring uniform distribution. The initial mixing during the turning process improves the quality of the carbon raw blocks after molding. 2. The material enters the limiting groove of the inner ring plate through the circular rib plate mounted on the outer wall of the positioning plate. Then, the auxiliary shaft, extension shaft and rotating shaft drive the spiral ring plate to rotate upward in a positive direction to convey the material. At the same time, they also drive the inclined blades on the outer wall of the inner ring plate to rotate in a positive direction on the filter screen plate, which agitates the material that is being conveyed to the filter screen plate. This allows the material to be distributed in the tank in a distribution manner after it is conveyed upward, thereby improving the uniformity of the material during the mixing process. 3. The positioning disc moves downward and enters the open ring. The circular rib plate on the outer wall of the positioning disc enters the inclined groove in the open ring, so that the auxiliary cylinder is driven by the rotating shaft. The inclined arc plate, side plate and upper frame plate on the outer wall of the auxiliary cylinder are in the tank, thereby performing frame-type stirring of the coke powder, binder and water in the tank to ensure the uniformity of the material distribution after stirring. 4. During the upward turning of the material, the spiral ring plate rotates forward, driving the powdery material that passes through the side groove into the auxiliary cylinder to be conveyed upward and enters the filter screen plate for secondary filtration. During the material stirring process, the open ring above the auxiliary cylinder is spliced ​​with the inclined groove and the round rib plate of the positioning plate. The motor drives the auxiliary cylinder to rotate, so that the inclined arc plate, upper arc plate and side plate installed on the outer wall of the auxiliary cylinder rotate in the tank to stir the material. This allows it to flexibly switch between material conveying function and stirring and mixing function to improve the efficiency of carbon raw block production. 5. During the process of introducing powdered materials, the circular ribs of the positioning disc enter the limiting groove of the inner ring plate. The motor rotates, causing the inclined blades on the outer wall of the inner ring plate to rotate on the filter screen. This disperses the material entering the tank, causing it to fall onto the filter screen. During the water injection process, water required for mixing is introduced into the tank through the water injection pipe. The water flow is introduced from the top side of the tank, impacting the inclined blades above the filter screen, causing them to rotate above the conical ring cylinder. This disperses the water flow, washing away the material remaining on the filter screen and causing it to fall into the tank. This allows for flexible switching between the material dispersion and introduction function and the cleaning function, ensuring the quality of the carbon raw material after mixing.

[0022] To enable those skilled in the art to better understand the present invention, 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. 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 should fall within the scope of protection of the present invention.

[0023] As described in the background art, the addition of coke powder and binder separately or in batches can easily lead to uneven distribution and layering, affecting the uniformity of mixing.

[0024] To solve this technical problem, the present invention provides a stirring device for roasting and pelletizing raw carbon blocks, which is applied in the field of raw carbon block production technology.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12A stirring device for calcining and pelletizing carbon raw blocks includes a tank body 1. A water injection pipe 2 is provided on the upper side of the outer wall of the tank body 1. A first feed pipe 3 is provided on one side of the upper surface of the tank body 1, and a second feed pipe 4 is provided on the other side of the upper surface of the tank body 1. A material turning assembly 5 is provided on the upper part of the tank body 1. The material turning assembly 5 includes an auxiliary cylinder 510 movably installed on the lower part of the inner wall of the tank body 1. Several side grooves 503 are evenly distributed in a circular pattern on the lower part of the outer wall of the auxiliary cylinder 510. A spiral ring plate 506 is movably connected to the inner wall of the auxiliary cylinder 510. A rotating shaft 505 is fixedly connected to the middle of the spiral ring plate 506. A filter screen plate 508 is movably connected above the auxiliary cylinder 510. The edge of the filter screen plate 508 is fixedly installed on the upper part of the inner wall of the tank body 1. An auxiliary shaft 504 is fixedly connected above the rotating shaft 505. An auxiliary component 6 is provided in the middle of the auxiliary shaft 504, which introduces coke powder and binder into the tank body through the first feed pipe 3 and the second feed pipe 4, respectively. In step 1, both coke powder and adhesive fall onto the filter screen 508 and then into the tank 1. At this time, the motor 501 is started to rotate forward. Through the connection between the auxiliary shaft 504, the extension shaft 502 and the rotating shaft 505, the spiral ring plate 506 is driven to rotate forward in the auxiliary cylinder 510. The coke powder and adhesive that fall at the bottom of the tank 1 are moved towards the auxiliary cylinder 510 in the middle of the inner wall of the tank 1 by the hemispherical structure of the lower part of the tank 1. They pass through the side groove 503 below the auxiliary cylinder 510 and enter the auxiliary cylinder 510, where they come into contact with the spiral ring plate 506. As the spiral ring plate 506 rotates forward, they are conveyed upward and undergo preliminary stirring and conveying in the auxiliary cylinder 510. After passing through the auxiliary cylinder 510, they are conveyed to the filter screen 508 for further filtration and then fall into the tank 1. This process of conveying and turning the powdery material upward is achieved.

[0029] By driving the spiral ring plate 506 to rotate forward with the motor 501, the powdery material entering the auxiliary cylinder 510 from the side groove 503 is conveyed upward to the filter screen plate 508 for secondary filtration. During the conveying process, the material is also stirred and mixed, so that the coke powder and binder can be conveyed and turned upward. After filtration, it falls into the tank 1, so that it is evenly distributed. The initial mixing during the turning process improves the quality of the carbon raw blocks after molding.

[0030] Furthermore, such as Figure 3 , Figure 6 and Figure 10 As shown, an extension shaft 502 is provided above the auxiliary shaft 504. A motor 501 is fixedly connected above the extension shaft 502 through the tank body 1. A frame-type stirring assembly 7 is provided below the motor 501. The motor 501 provides power for the rotation of the rotating shaft 505 through the transmission connection between the extension shaft 502 and the auxiliary shaft 504.

[0031] Furthermore, such as Figure 3 , Figure 4 and Figure 8 As shown, a positioning ring frame 507 is fixedly connected to the lower edge of the filter screen plate 508. Several arc-shaped ribs 509 are evenly distributed and fixedly installed on the upper part of the positioning ring frame 507, and the arc-shaped ribs 509 are located on the lower surface of the filter screen plate 508. The filter screen plate 508 is supported by the several arc-shaped ribs 509 connected to the upper part of the positioning ring frame 507, which increases the stability of the material filtration process.

[0032] Example 2 further optimizes the stirring device for roasting and pelletizing carbon raw blocks provided in Example 1. Specifically, as follows: Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the auxiliary component 6 includes an elastic telescopic rod 605 fixedly installed in the middle of the auxiliary shaft 504. A positioning plate 607 is fixedly connected to one end of the rotating shaft 505 near the elastic telescopic rod 605. Several circular ribs 606 are fixedly connected to the outer wall of the positioning plate 607 in a circumferentially evenly distributed manner. Several inclined blades 601 are movably installed on the upper surface of the filter screen plate 508 in a circumferentially evenly distributed manner. An inner ring plate 602 is fixedly connected to the middle of the several inclined blades 601. Several limiting grooves 604 are evenly distributed in a circumferential manner below the inner ring plate 602. When the electric telescopic rod 702 extends, it lifts the auxiliary shaft 504, the extension shaft 502 and the rotating shaft 505 upward, so that the positioning plate 607 connected to the elastic telescopic rod 605 in the auxiliary shaft 504 moves upward synchronously, driving the circular ribs 606 on the outer wall of the positioning plate 607 to move upward. Rib 606 passes through the positioning groove 608 of the conical annular cylinder 609 and enters the limiting groove 604 of the inner annular plate 602. If the rib 606 does not enter the positioning groove 608, the elastic telescopic rod 605 will be stretched during the upward lifting process of the electric telescopic rod 702. At this time, the motor 501 starts to rotate normally and slowly, and first enters the positioning groove 608 of the conical annular cylinder 609, and then enters the limiting groove 604 of the inner annular plate 602 that is aligned with it. After the docking is completed, the speed of the motor 501 increases and rotates in the forward direction, which drives the inclined blades 601 on the outer wall of the inner annular plate 602 to rotate above the filter screen plate 508 with the auxiliary shaft 504 as the central axis, stirring the material falling on the filter screen plate 508, so that the material passes through the filter screen plate 508 and is evenly dispersed inside the tank 1.

[0033] The circular rib plate 606 mounted on the outer wall of the positioning plate 607 enters the limiting groove 604 of the inner ring plate 602. Then, the auxiliary shaft 504, the extension shaft 502 and the rotating shaft 505 drive the spiral ring plate 506 to rotate upward and convey the material. At the same time, they also drive the inclined blades 601 on the outer wall of the inner ring plate 602 to rotate upward on the filter screen plate 508. This agitates the material that is being conveyed above the filter screen plate 508, thereby enabling the material to be distributed in the tank 1 in a distributing manner after it is conveyed upward, thus improving the uniformity of the material during the mixing process.

[0034] Furthermore, such as Figure 4 and Figure 10 As shown, a conical ring cylinder 609 is fixedly connected to the middle of the upper surface of the filter plate 508. Several positioning grooves 608 are evenly distributed around the outer wall of the conical ring cylinder 609. The powder material can be guided to flow out through the positioning grooves 608 on the outer wall of the conical ring cylinder 609.

[0035] Furthermore, such as Figure 4 , Figure 9 , Figure 10 and Figure 11 As shown, an annular groove 603 is provided below the inner ring plate 602, and the inner ring plate 602 is sleeved on the outer wall of the conical ring cylinder 609 with an inclined groove 709. The inner ring plate 602 is sleeved on the conical ring cylinder 609 above the filter screen plate 508 through the annular groove 603 below the inner ring plate 602, so as to cooperate with the inner ring plate 602 to drive the inclined blade 601 to rotate on the filter screen plate 508.

[0036] Example 3 further optimizes the stirring device for roasting and pelletizing carbon raw blocks provided in Examples 1 and 2. Specifically, as follows: Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12As shown, the frame-type stirring assembly 7 includes a fixed circular plate 701 fixedly installed below the outer wall of the motor 501. Several electric telescopic rods 702 are fixedly connected to the lower surface of the fixed circular plate 701 in a circumferentially evenly distributed manner. Several inclined arc plates 704 are fixedly connected to the lower surface of the outer wall of the auxiliary cylinder 510 in a circumferentially evenly distributed manner. A side plate 705 is fixedly connected to the end of the inclined arc plate 704 away from the auxiliary cylinder 510, and the side plate 705 is movably connected to the inner wall of the tank 1. An upper arc plate 706 is fixedly connected to the middle of the side plate 705 near the auxiliary cylinder 510. An open ring 708 is fixedly connected to the upper part of the auxiliary cylinder 510, and the open ring 708 is movably installed on the lower surface of the filter screen plate 508. Several inclined grooves 709 are evenly distributed on the inner wall of the open ring 708. When the electric telescopic rods 702 retract, they drive the auxiliary shaft 504, the extension shaft 502, and the rotating shaft 505 to move downwards synchronously. The positioning disk 607 in the middle of the auxiliary shaft 504 moves downward synchronously. The circular rib plate 606 on the outer wall of the positioning disk 607 passes down through the positioning groove 608 of the conical ring cylinder 609 and enters the open ring 708. If it is not aligned with the inclined groove 709 in the open ring 708, the elastic telescopic rod 605 will retract. With the slow start of the motor 501, the angle of the positioning disk 607 is changed, which drives the circular rib plate 606 into the inclined groove 709 in the open ring 708. After entering, the motor 501 continues to rotate, which drives the auxiliary cylinder 510 to rotate below the filter screen plate 508, which drives multiple inclined arc plates 704 to stir at the bottom of the tank 1. The side plate 705 above the inclined arc plate 704 scrapes the material adhering to the inner wall of the tank 1 and removes it. The upper arc plate 706 in the middle of the side plate 705 stirs the material in the middle of the tank 1, thereby stirring the material in the tank 1.

[0037] The positioning disc 607 moves downward and enters the open ring 708. The circular rib plate 606 on the outer wall of the positioning disc 607 enters the inclined groove 709 in the open ring, causing the auxiliary cylinder 510 to be driven by the rotating shaft 505. The inclined arc plate 704, side plate 705 and upper frame plate on the outer wall of the auxiliary cylinder 510 are in the tank body 1, thereby performing frame-type stirring of the coke powder, binder and water in the tank body 1 to ensure the uniformity of the material distribution after stirring.

[0038] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, several electric telescopic rods 702 are fixedly connected to a support circular plate 703 at their bottom ends. The support circular plate 703 is fixedly installed on the upper surface of the tank body 1. The support circular plate 703 is connected to the upper part of the tank body 1 to ensure that there is a stable fulcrum during the adjustment process of the rotating shaft 505.

[0039] Furthermore, such as Figure 5 and Figure 6As shown, several upper arc plates 706 are fixedly connected to an upper ring plate 707 in the middle. The inner wall of the upper ring plate 707 is fixedly installed in the middle of the outer wall of the auxiliary cylinder 510. The upper arc plates 706 are fixed to the outer wall of the auxiliary cylinder 510 through the upper ring plate 707 to ensure stability during the rotation and stirring process.

[0040] Furthermore, such as Figure 5 , Figure 6 and Figure 7 As shown, a lower conical ring 710 is fixedly connected below the auxiliary cylinder 510, and the lower conical ring 710 is located above the side groove 503. The outer wall of the lower conical ring 710 is fixedly connected to the upper middle part of several inclined arc plates 704. The lower conical ring 710 further fixes the inclined arc plates 704, increasing the stability of the inclined arc plates 704 during rotation.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, a discharge pipe 8 is fixedly connected to the lower center of the tank body 1. The material that has been stirred in the tank body 1 is discharged through the discharge pipe 8. Several support rods 9 are fixedly connected in a circular and uniform manner on the lower surface of the tank body 1. A pad 10 is fixedly connected to the bottom end of the support rod 9. The support rods 9 and the pad 10 support the tank body 1 to ensure the stability of the tank body 1 during the stirring operation.

[0042] The process of using the stirring device for roasting and pelletizing raw carbon blocks provided by this invention is as follows: Working principle: The staff uses the support rod 9 to support the tank 1 and place it in a suitable position in the factory area, and places the pad 10 at the bottom of the support rod 9 to ensure its stability. Feeding: Coke powder and binder are introduced into tank 1 through first feed pipe 3 and second feed pipe 4. At this time, electric telescopic rod 702 extends, raising auxiliary shaft 504, extension shaft 502 and rotating shaft 505 upward, so that positioning plate 607 connected to the auxiliary shaft 504 by elastic telescopic rod 605 moves upward synchronously, driving the circular rib plate 606 on the outer wall of positioning plate 607 through the positioning groove 608 of conical ring cylinder 609 and into the limiting groove 604 of inner ring plate 602. If the circular rib plate 606 Before entering the positioning groove 608, the elastic telescopic rod 605 is stretched during the upward lifting process of the electric telescopic rod 702. At this time, the motor 501 starts to rotate slowly and normally, first entering the positioning groove 608 of the conical ring cylinder 609, and then entering the limiting groove 604 of the inner ring plate 602 that is aligned with it. After the docking is completed, the speed of the motor 501 increases and rotates in the forward direction, which drives the inclined blades 601 on the outer wall of the inner ring plate 602 to move above the filter screen plate 508 with the auxiliary shaft 50. Rotating around the central axis 4, the material falling onto the filter screen 508 is agitated, allowing it to pass through the filter screen 508 and be evenly dispersed inside the tank 1. Simultaneously, the connection between the auxiliary shaft 504, the extension shaft 502, and the rotating shaft 505 drives the spiral ring plate 506 to rotate forward within the auxiliary cylinder 510. The coke powder and adhesive falling at the bottom of the tank 1, along with the hemispherical structure of the lower part of the tank 1, move closer to the auxiliary cylinder 510 in the middle of the inner wall of the tank 1 and pass through the auxiliary cylinder 510. The side groove 503 below 0 enters the auxiliary cylinder 510 and contacts the spiral ring plate 506. As the spiral ring plate 506 rotates in the forward direction, it is conveyed upward and initially stirred and conveyed in the auxiliary cylinder 510. It passes through the conical ring cylinder 609 above the auxiliary cylinder 510, is blocked by the positioning plate 607, passes through the positioning groove 608 on the outer wall of the conical ring cylinder 609, and is conveyed to the filter screen plate 508 for further filtration before falling into the tank 1. This process is used to convey and turn the powdered material upward. Water Injection: After mixing is complete, the electric telescopic rod 702 retracts, extending the connection between the extension shaft 502, auxiliary shaft 504, and rotating shaft 505. This pushes the circular rib plate 606 in the limiting groove 604 away from the inner ring plate 602 and into the conical ring cylinder 609, without contacting the positioning groove 608. After completion, the motor 501 is started to rotate in the opposite direction, causing the rotating shaft 505 to drive the spiral ring plate 506 to rotate in the auxiliary cylinder 510. The material remaining in the auxiliary cylinder 510 is discharged through the side groove 503 and enters the tank 1. Simultaneously, water is injected into the tank 1 through the water injection pipe 2. Water is introduced into the tank 1 from the top side, which impacts the inclined blades 601 above the filter screen 508, causing them to rotate above the conical ring cylinder 609. This disperses the water flow, washing away the material remaining on the filter screen 508 and causing it to fall into the tank 1. At the same time, the water also enters the auxiliary cylinder 510, working in conjunction with the rotating spiral ring plate 506 in the auxiliary cylinder 510 to rinse the auxiliary cylinder 510. This completes the water injection and cleaning operation, preventing material from remaining on the filter screen 508 and affecting the quality of the mixed material. Stirring: After water injection is complete, the electric telescopic rod 702 is restarted for further retraction, causing the positioning disc 607 in the auxiliary shaft 504 to move downwards synchronously. The circular rib plate 606 on the outer wall of the positioning disc 607 passes downwards through the positioning groove 608 of the conical annular cylinder 609 and enters the open ring 708. If the inclined groove 709 in the open ring 708 is not aligned, the elastic telescopic rod 605 will retract, changing the angle of the positioning disc 607 under the slow start of the motor 501. After alignment, the elastic telescopic rod 605 pushes the circular rib plate 606 on the outer wall of the positioning disc 607 to retract. Rib 606 enters the inclined groove 709, which in turn drives the circular rib 606 into the inclined groove 709 in the open ring 708. After entering, the motor 501 rotates in the opposite direction, which drives the auxiliary cylinder 510 to rotate below the filter screen plate 508. This drives multiple inclined arc plates 704 to stir at the bottom of the tank 1. The side plate 705 above the inclined arc plate 704 scrapes the material adhering to the inner wall of the tank 1 and removes it. The upper arc plate 706 in the middle of the side plate 705 stirs the material in the middle of the tank 1, thereby stirring the material in the tank 1. Discharge: After stirring for a certain period of time, the rotation stops, and the electric telescopic rod 702 is activated to extend. The auxiliary shaft 504 and the extension shaft 502 work together to drive the positioning plate 607 upward and into the middle of the conical ring cylinder 609 without contacting the positioning groove 608. At this time, the motor 501 rotates in the opposite direction, driving the auxiliary shaft 504, the extension shaft 502 and the rotating shaft 505 to rotate. This causes the spiral ring plate 506 in the auxiliary cylinder 510 to rotate in the opposite direction synchronously. The material after stirring and mixing passes through the side groove 503 and enters the auxiliary cylinder 510. At this time, the discharge pipe 8 is opened, and the spiral ring plate 506 rotates in the opposite direction to squeeze the material into the discharge pipe 8, thereby improving the efficiency of material discharge. Discharge Assistance: When the discharge becomes slow, the electric telescopic rod 702 is activated to extend, pushing the circular rib plate 606 connected to the positioning plate 607 into the inclined groove 709 of the open ring 708. The motor 501 rotates, driving the auxiliary cylinder 510 to rotate slowly, so that the inclined arc plate 704 and the side plate 705 scrape the inner wall of the tank 1, scraping the material adhering to the inner wall of the tank 1, so that it passes through the side groove 503 of the auxiliary cylinder 510 and enters the discharge pipe 8 for discharge.
