Description

Technical Field

[0001] This invention relates to the field of material storage tank recycling and cleaning technology, specifically to a material storage tank recycling and cleaning equipment and method. Background Technology

[0002] Material storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. These tanks are widely used in North China and, depending on the material, generally include: polyethylene tanks, polypropylene tanks, fiberglass tanks, ceramic tanks, rubber tanks, and stainless steel tanks. After storing chemical substances or other materials, the residual material on the inner walls of the storage tanks can be cleaned and reused, reducing production costs and resource waste for enterprises.

[0003] In existing technologies, cleaning equipment is generally used to clean the interior of recycled material storage tanks. However, when cleaning the interior of large-diameter tanks using existing cleaning equipment, if water is used directly for rinsing, the flow rate required to achieve effective cleaning water pressure would be extremely high, which is impractical for users. Furthermore, if the cleaning equipment cannot achieve the required pressure, the cleaning effect on the interior of large-diameter tanks will be poor, rendering the cleaning equipment unable to meet user needs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material storage tank recycling and cleaning device and method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material storage tank recycling and cleaning device includes a base, a top plate mounted on the top of the base via a telescopic cylinder, a vertical rod mounted on the bottom of the top plate, movable plates connected to both outer walls of the vertical rod via telescopic mechanisms, a cleaning mechanism for cleaning the inside of a large material tank on the outer wall of the two movable plates that are far apart, and a suction mechanism for pumping cleaning wastewater from inside the material tank to the outside at the bottom of the vertical rod.

[0007] Optionally, a first drive motor is installed on the top of the top plate, and the output end of the first drive motor is connected to the top of the vertical rod.

[0008] Optionally, the telescopic mechanism includes first sliding grooves opened on the outer walls of both sides of the vertical rod, and two first sliding blocks are installed inside each of the two first sliding grooves. A first rotating block is rotatably installed at the end of each of the two first sliding blocks away from the first sliding groove.

[0009] Optionally, the ends of the two first rotating blocks away from the first slider are each connected to a second rotating block via an electric telescopic rod. A second sliding groove is provided on the outer wall of the moving plate near the vertical rod. Two second sliders are installed inside the second sliding groove, and the two second rotating blocks are respectively rotatably installed inside the second sliders that are close to them.

[0010] Optionally, a double-ended lead screw is installed inside the second groove, and two second sliders respectively cooperate with the outer walls of the two ends of the double-ended lead screw.

[0011] Optionally, the cleaning mechanism includes two hollow plates, and connecting plates are installed on the same two outer walls of the two hollow plates and the two movable plates. The two adjacent connecting plates are connected by bolts and threads. The top of the two hollow plates is equipped with a connecting end for communicating with an external water supply mechanism, and the bottom of the two hollow plates is rotatably equipped with a protrusion via a rotating shaft.

[0012] Optionally, grooves are provided inside the two hollow plates at their opposite ends, and multiple nozzles are installed inside the two grooves. Two first scrapers are symmetrically hinged to the opposite ends of the two hollow plates, and a cleaning brush is installed on one side of the outer wall of one of the first scrapers.

[0013] Optionally, the suction mechanism includes a second drive motor installed at the bottom of the vertical rod, a third slider installed at the output end of the second drive motor, a suction head at the bottom of the vertical rod, a third groove for the third slider to slide on the top of the suction head, the outer walls on both sides of the third slider being connected to the inner wall of the third groove by springs, and multiple suction nozzles at the bottom of the suction head.

[0014] Optionally, the outer walls on both sides of the suction head are provided with a fourth sliding groove, and a fourth slider is installed inside each of the two fourth sliding grooves. A mounting seat is installed at the end of each of the two fourth sliders away from the fourth sliding groove, and a second scraper is rotatably installed inside each of the two mounting seats.

[0015] Optionally, a method for recycling and cleaning a material storage tank, the method using the cleaning equipment described above, and the method further comprising the following steps:

[0016] Step 1: First, control the telescopic cylinder to extend upwards to its maximum length, causing the vertical rod and suction head to move upwards together. Then, place the material container to be cleaned on top of the base, control the telescopic cylinder to retract downwards to return to its original position, causing the vertical rod and suction head to move downwards into the material container. Depending on the size of the material container, control the two double-headed screws to rotate, causing the two second sliders to move towards each other, which in turn causes the two electric telescopic rods to move towards each other, and causes the moving plate to move away from the vertical rod.

[0017] Step 2: After moving the moving plate and cleaning mechanism to a position close to the inner wall of the material tank using two electric telescopic rods, the external water supply mechanism can be controlled to deliver water to the inside of the two hollow plates and spray it outwards onto the inner wall of the material tank through multiple nozzles to wash away the dirt attached to the inner wall of the material tank. At this time, the first drive motor can be controlled simultaneously to drive the vertical rod to rotate inside the material tank, thereby driving the two cleaning mechanisms to rotate inside the material tank, so that the multiple nozzles can spray water evenly on the inner wall of the material tank, and more thoroughly wash the inner wall of the material tank.

[0018] Step 3: After the rinsing work of multiple nozzles is completed, continue to control the rotation of the two double-headed screws or control the extension of the extension ends of the two electric telescopic rods, so that the two first scrapers set at the end of the two hollow plates near the inner wall of the material tank abut against the inner wall of the material tank. As the first drive motor drives the vertical rod to continue to rotate, it can drive the two first scrapers to scrape and clean the dirt on the inner wall of the material tank. After the multiple first scrapers have scraped the dirt on the inner wall of the material tank, control multiple first scrapers to rotate 90 degrees away from the hollow plates, so that two of the first scrapers drive one side of the outer wall of the cleaning brush to a position close to the material tank. At this time, the two cleaning brushes can scrub the dirt on the inner wall of the material tank that the first scrapers cannot scrape off while the vertical rod rotates.

[0019] Step 4: After cleaning the arc-shaped inner wall of the material tank, control the two second scrapers to rotate downwards 180 degrees inside the mounting base, so that the two second scrapers extend. By controlling the extension and retraction of the telescopic cylinder, the two second scrapers are brought into contact with the bottom inner wall of the material tank. According to the size of the material tank, control the two fourth sliders to move away from each other inside the corresponding fourth slide groove, so that the two second scrapers can adapt to the diameter of the bottom surface of the material tank of different sizes. With the help of the second drive motor, the suction head and the two second scrapers are rotated, so that the two second scrapers can scrape the dirt on the bottom surface of the material tank during the rotation, so as to achieve a thorough cleaning of the inner wall of the material tank.

[0020] The beneficial effects of this invention are:

[0021] 1. In this invention, by means of a telescopic mechanism, when cleaning the inside of a material tank with a larger diameter, two double-headed lead screws can be controlled to rotate, driving two second sliders to move towards each other, which in turn drives two electric telescopic rods to move towards each other, and drives the moving plate to move away from the vertical rod. This allows the moving plate and the cleaning mechanism to move close to the inner wall of the material tank, and water is sprayed onto the inner wall of the material tank through multiple nozzles to wash away the dirt attached to the inner wall of the material tank. This allows the cleaning mechanism to adapt to cleaning the inside of material tanks with a larger diameter without increasing the pressure of the cleaning mechanism, thus reducing the company's costs.

[0022] 2. In this invention, the first drive motor and the first scraper are configured so that the vertical rod continues to rotate as the first drive motor drives the two first scrapers to scrape and clean the dirt on the inner wall of the material tank. After the first scrapers have scraped the dirt off the inner wall of the material tank, they are controlled to rotate 90 degrees away from the hollow plate. This causes two of the first scrapers to rotate one side of the outer wall of the cleaning brush to a position close to the material tank. At this time, the two cleaning brushes can brush the dirt that the first scrapers cannot scrape off from the inner wall of the material tank while the vertical rod is rotating. This allows the cleaning mechanism to perform three cleaning processes on the inner wall of the material tank in sequence: rinsing, scraping, and brushing. This further improves the cleaning effect on the inner wall of the material tank and facilitates the subsequent recycling and reuse of the material tank.

[0023] 3. In this invention, after cleaning the arc-shaped inner wall of the material tank, the two second scrapers can be controlled to rotate downwards by 180 degrees inside the mounting base, so that the two second scrapers rotate and extend. By controlling the extension and retraction of the telescopic cylinder, the two second scrapers are driven to contact the bottom inner wall of the material tank. According to the size of the material tank, the two fourth sliders are controlled to move away from each other inside the corresponding fourth slide groove, so that the two second scrapers can adapt to the diameter of the bottom surface of the material tank of different sizes. With the help of the second drive motor, the suction head and the two second scrapers are driven to rotate, so that the two second scrapers can scrape the dirt on the bottom surface of the material tank during the rotation of the bottom surface of the material tank, thereby achieving a thorough cleaning of the inner wall of the material tank.

[0024] 4. In this invention, after the inner wall of the material tank is cleaned, the external suction mechanism can be activated to drive multiple suction nozzles to suction the wastewater inside the material tank and pump it to the outside of the material tank. During the suction process, one set of first sliders is controlled to move downward inside the first slide groove, which drives one of the protrusions to move downward to a position flush with the suction head. The protrusion rotates and pushes the suction head to swing back and forth with the elasticity of two springs, so that impurities in the cleaning wastewater are less likely to clog the multiple suction nozzles, thereby improving the efficiency of multiple suction nozzles in suctioning cleaning wastewater.

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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 are within the scope of protection of the present invention.

[0035] Reference Figures 1-7 A material storage tank recycling and cleaning device includes a base 1. A top plate 3 is mounted on the top of the base 1 via a telescopic cylinder 2. A vertical rod 5 is mounted on the bottom of the top plate 3. Movable plates 6 are connected to both outer walls of the vertical rod 5 via telescopic mechanisms. A cleaning mechanism for cleaning the interior of large material tanks is provided on the outer wall of the two movable plates 6 on the side furthest from each other. A suction mechanism for drawing cleaning wastewater from inside the material tank to the outside is provided at the bottom of the vertical rod 5. The top plate 3 can be moved up and down by extending and retracting the telescopic end of the telescopic cylinder 2.

[0036] As a technical optimization of the present invention, a first drive motor 4 is installed on the top of the top plate 3, and the output end of the first drive motor 4 is connected to the top end of the vertical rod 5. The first drive motor 4 can drive the vertical rod 5 to rotate synchronously.

[0037] As an optimized technical solution of the present invention, the telescopic mechanism includes first sliding grooves 12 formed on the outer walls of both sides of the vertical rod 5. Two first sliders 13 are installed inside each of the two first sliding grooves 12, and a first rotating block 21 is rotatably mounted at the end of each of the two first sliders 13 away from the first sliding groove 12. Drive screws are pre-installed inside each of the two first sliding grooves 12. During rotation, the two drive screws can respectively drive the two first sliders 13 to move up and down inside the first sliding groove 12. The drive screws can be driven by an external drive device.

[0038] As a technical optimization of the present invention, the ends of the two first rotating blocks 21 away from the first slider 13 are each connected to a second rotating block 22 via an electric telescopic rod 11. The outer wall of the moving plate 6 near the vertical rod 5 is provided with a second sliding groove 18. Two second sliders 20 are installed inside the second sliding groove 18, and the two second rotating blocks 22 are respectively rotatably installed inside the second sliders 20 that are close to them.

[0039] As a technical optimization of the present invention, a double-ended lead screw 19 is installed inside the second slide groove 18, and two second sliders 20 respectively cooperate with the outer walls of the two ends of the double-ended lead screw 19. In actual use, one end of the double-ended lead screw 19 is connected to the output end of a preset drive device. The drive device can drive the double-ended lead screw 19 to rotate in both directions, thereby driving the two second sliders 20 to move towards or away from each other inside the second slide groove 18. When the two second sliders 20 move towards each other, they can drive the two electric telescopic rods 11 to rotate towards each other, making the distance between the moving plate 6 and the vertical rod 5 larger, and vice versa. This allows the moving plate 6 and the cleaning mechanism to be adjusted according to the size of the material tank, so that the cleaning mechanism can adapt to the cleaning of the inner wall of material tanks of different sizes.

[0040] As an optimized technical solution of the present invention, the cleaning mechanism includes two hollow plates 23. Connecting plates 15 are installed on the same two outer walls of both hollow plates 23 and two movable plates 6. Two adjacent connecting plates 15 are threadedly connected by bolts 16. Connecting ends 14 for communication with an external water conveying mechanism are installed on the top of each hollow plate 23. Protrusions 10 are rotatably installed on the bottom of each hollow plate 23 via a rotating shaft. The hollow plates 23 and the movable plates 6 are detachably installed, allowing the hollow plates 23 to be replaced as needed, facilitating other operations on the inner wall of the material tank, such as applying corrosion-resistant paint.

[0041] As a technical optimization of the present invention, grooves 25 are formed inside the two hollow plates 23 at their far ends, and multiple nozzles 26 are installed inside the two grooves 25. Two first scrapers 17 are symmetrically hinged to the far ends of the two hollow plates 23, and a cleaning brush 24 is installed on one side of the outer wall of one of the first scrapers 17. The connection end 14 is connected to an external water supply mechanism, so that the water discharged by the external water supply mechanism can be sprayed onto the inner wall of the material tank through the multiple nozzles 26 to rinse the inner wall of the material tank; and in conjunction with the rotating first scraper 17 and cleaning brush 24, the inner wall of the material tank can be scrubbed.

[0042] As a technical optimization of the present invention, the suction mechanism includes a second drive motor 7 installed at the bottom of the vertical rod 5. A third slider 28 is installed at the output end of the second drive motor 7. A suction head 8 is provided at the bottom of the vertical rod 5. A third groove 27 is provided on the top of the suction head 8 for the third slider 28 to slide. The outer walls on both sides of the third slider 28 are connected to the inner wall of the third groove 27 by springs 29. Multiple suction nozzles 33 are provided at the bottom of the suction head 8. The suction head 8 can be connected to an external suction mechanism through a hose, so that the wastewater from cleaning inside the material tank can be suctioned to the outside through the multiple suction nozzles 33.

[0043] As a technical optimization of the present invention, the outer walls of both sides of the suction head 8 are provided with fourth sliding grooves 30, and a fourth slider 31 is installed inside each of the two fourth sliding grooves 30. A mounting base 32 is installed at the end of each of the two fourth sliders 31 away from the fourth sliding groove 30, and a second scraper 9 is rotatably installed inside each of the two mounting bases 32. A linear motor is pre-installed inside the fourth sliding groove 30, and the linear motor can drive the fourth slider 31 to move back and forth inside the fourth sliding groove 30.

[0044] As a technical optimization of the present invention, a method for recycling and cleaning a material storage tank is provided. This cleaning method uses the cleaning equipment described above and further includes the following steps:

[0045] Step 1: First, control the telescopic cylinder 2 to extend upward to its maximum length, causing the vertical rod 5 and suction head 8 to move upward together. Then, place the material container to be cleaned on top of the base 1, control the telescopic cylinder 2 to retract downward to return to its original position, causing the vertical rod 5 and suction head 8 to move downward to the inside of the material container. Depending on the size of the material container, control the two double-headed screws 19 to rotate, causing the two second sliders 20 to move towards each other, causing the two electric telescopic rods 11 to move towards each other, and causing the moving plate 6 to move away from the vertical rod 5.

[0046] Step 2: After the two electric telescopic rods 11 move the moving plate 6 and the cleaning mechanism to a position close to the inner wall of the material tank, the external water supply mechanism can be controlled to deliver water to the inside of the two hollow plates 23 and spray it outwards onto the inner wall of the material tank through multiple nozzles 26 to wash away the dirt attached to the inner wall of the material tank. At this time, the first drive motor 4 can be controlled to drive the vertical rod 5 to rotate inside the material tank, thereby driving the two cleaning mechanisms to rotate inside the material tank, so that the multiple nozzles 26 can spray water evenly on the inner wall of the material tank, and wash the inner wall of the material tank more thoroughly.

[0047] Step 3: After the rinsing work of multiple nozzles 26 is completed, continue to control the rotation of the two double-headed screws 19 or control the extension of the extension end of the two electric telescopic rods 11, so that the two first scrapers 17 set at the end of the two hollow plates 23 near the inner wall of the material tank abut against the inner wall of the material tank. As the first drive motor 4 drives the vertical rod 5 to continue to rotate, the two first scrapers 17 can scrape and clean the dirt on the inner wall of the material tank. After the multiple first scrapers 17 scrape the dirt on the inner wall of the material tank, control the multiple first scrapers 17 to rotate 90 degrees away from the hollow plates 23, so that the two first scrapers 17 drive one side of the outer wall of the cleaning brush 24 to rotate to a position close to the material tank. At this time, the two cleaning brushes 24 can brush the dirt that the first scrapers 17 cannot scrape off on the inner wall of the material tank while the vertical rod 5 is rotating.

[0048] Step 4: After cleaning the arc-shaped inner wall of the material tank, control the two second scrapers 9 to rotate downwards by 180 degrees inside the mounting base 32, so that the two second scrapers 9 rotate and extend. By controlling the extension and retraction of the telescopic cylinder 2, the two second scrapers 9 are driven to contact the bottom inner wall of the material tank. According to the size of the material tank, control the two fourth sliders 31 to move away from each other inside the corresponding fourth slide groove 30, so that the two second scrapers 9 can adapt to the diameter of the bottom surface of the material tank of different sizes. With the help of the second drive motor 7, drive the suction head 8 and the two second scrapers 9 to rotate, so that the two second scrapers 9 can scrape the dirt on the bottom surface of the material tank during the rotation of the bottom surface of the material tank, so as to achieve a thorough cleaning of the inner wall of the material tank.

[0049] In this invention, when the user uses the device, first, the telescopic cylinder 2 is controlled to extend upward to its maximum length, causing the vertical rod 5 and suction head 8 to move upward together. Then, the material container to be cleaned is placed on top of the base 1, and the telescopic cylinder 2 is controlled to retract downward to return to its original position, causing the vertical rod 5 and suction head 8 to move downward into the interior of the material container. Depending on the size of the material container, the two double-headed screws 19 are controlled to rotate, causing the two second sliders 20 to move towards each other, which in turn causes the two electric telescopic rods 11 to move towards each other, and causes the moving plate 6 to move away from the vertical rod 5. If the diameter of the material container exceeds the length of the telescopic ends of the two electric telescopic rods 11 before they extend, the telescopic ends of the two electric telescopic rods 11 can be controlled to extend, further increasing the distance between the moving plate 6 and the vertical rod 5, so that the cleaning mechanism can accommodate material containers with larger diameters.

[0050] After the two electric telescopic rods 11 move the movable plate 6 and the cleaning mechanism to a position close to the inner wall of the material tank, the external water supply mechanism can be controlled to deliver water to the inside of the two hollow plates 23, and spray it outwards onto the inner wall of the material tank through multiple nozzles 26 to wash away the dirt attached to the inner wall of the material tank. At this time, the first drive motor 4 can be controlled to drive the vertical rod 5 to rotate inside the material tank, thereby driving the two cleaning mechanisms to rotate inside the material tank, so that the multiple nozzles 26 can spray water evenly on the inner wall of the material tank, and wash the inner wall of the material tank more thoroughly. In order to improve the cleanliness of the dirt on the inner wall of the material tank, the cleaning agent can be added to the inside of the external water supply mechanism, so that the cleaning agent can combine with the dirt and improve the cleaning effect of the inner wall of the material tank.

[0051] After spraying water mixed with cleaning agent onto the inner wall of the material tank, wait for a period of time to allow the cleaning agent to react with the dirt adhering to the inner wall of the material tank. Then, continue to control the rotation of the two double-headed screws 19 or control the extension of the telescopic ends of the two electric telescopic rods 11. This causes the two first scrapers 17, located near the inner wall of the two hollow plates 23, to come into contact with the inner wall of the material tank. As the first drive motor 4 drives the vertical rod 5 to continue rotating, the two first scrapers 17 can scrape and clean the dirt on the inner wall of the material tank. The multiple first scrapers 17 then clean the material tank... After the dirt on the inner wall is scraped off, multiple first scrapers 17 are controlled to rotate 90 degrees away from the hollow plate 23. This causes two of the first scrapers 17 to rotate one side of the outer wall of the cleaning brush 24 to a position close to the material tank. At this time, the two cleaning brushes 24 can brush the dirt that the first scrapers 17 cannot scrape off from the inner wall of the material tank while the vertical rod 5 is rotating. This allows the cleaning mechanism to perform three cleaning operations on the inner wall of the material tank in sequence: rinsing, scraping and brushing. This further improves the cleaning effect on the inner wall of the material tank and facilitates the subsequent recycling and reuse of the material tank.

[0052] After cleaning the arc-shaped inner wall of the material tank, the two second scrapers 9 can be controlled to rotate downwards by 180 degrees inside the mounting base 32, so that the two second scrapers 9 rotate and extend. By controlling the extension and retraction of the telescopic cylinder 2, the two second scrapers 9 are driven to contact the bottom inner wall of the material tank. According to the size of the material tank, the two fourth sliders 31 are controlled to move away from each other inside the corresponding fourth slide groove 30, so that the two second scrapers 9 can adapt to the diameter of the bottom surface of the material tank of different sizes. With the help of the second drive motor 7, the suction head 8 and the two second scrapers 9 are driven to rotate, so that the two second scrapers 9 can scrape the dirt on the bottom surface of the material tank during the rotation of the bottom surface of the material tank, so as to achieve a thorough cleaning of the inner wall of the material tank.

[0053] After the inner wall of the material tank is cleaned, the external suction mechanism can be activated to drive multiple suction nozzles 33 to suction the wastewater from inside the material tank and remove it to the outside. Since the wastewater contains many impurities, to prevent these impurities from clogging the suction nozzles 33, during the suction process, one set of first sliders 13 can be controlled to move downwards inside the first slide groove 12. This moves one of the moving plates 6 downwards, causing the protrusions 10 at the bottom of the moving plate 6 to move downwards until they are flush with the suction head 8. This is achieved by controlling... One of the double-headed lead screws 19 rotates, causing the two second sliders 20 to move away from each other, thus reducing the distance between one of the moving plates 6 and the vertical rod 5. This causes the protrusion 10 to abut against one side of the outer wall of the suction head 8. The protrusion 10 is rotated by a drive device pre-set inside the bottom of the moving plate 6. Since the protrusion 10 is elliptical, it can push the suction head 8 to swing back and forth with the help of the elasticity of the two springs 29 during the rotation of the protrusion 10. This makes it less likely for impurities in the cleaning wastewater to clog the multiple suction nozzles 33, thereby improving the efficiency of the multiple suction nozzles 33 in sucking up the cleaning wastewater.

[0054] After cleaning the inner wall of the material tank, if a dent or deformation is found, to facilitate the subsequent recycling and reuse of the material tank, the first drive motor 4 can drive the vertical rod 5 to rotate, allowing one of the movable plates 6 to move close to the dented deformation position of the material tank. This controls both first scrapers 17 to rotate and reset, and controls the corresponding double-headed screw 19 to rotate, driving the two second sliders 20 to move towards each other. This causes the movable plate 6 and the two first scrapers 17 to come into close contact with the dented deformation area of ​​the material tank. As the two second sliders 20 continue to move towards each other, they push the two first scrapers 17 to squeeze and push the dented deformation area of ​​the material tank's inner wall, thereby achieving the effect of shaping and repairing the dented deformation area of ​​the material tank's inner wall, facilitating the subsequent recycling and reuse of the material tank.

[0055] After the cleaning of the material tank is completed, the telescopic cylinder 2 can be controlled to extend upward again, driving the vertical rod 5 to move upward from inside the material tank. At this time, multiple first scrapers 17 rotate to a state flush with the hollow plate 23, so that two of the first scrapers 17 with cleaning brushes 24 rotate to a position close to multiple nozzles 26. At this time, the water sprayed outward from multiple nozzles 26 can wash the cleaning brushes 24, making it easier to clean the impurities trapped inside the cleaning brushes 24, which is beneficial for the subsequent use of the cleaning brushes 24.

6. A method for recycling and cleaning material storage tanks, characterized in that, The cleaning method uses the cleaning equipment described in claim 5, and the cleaning method further includes the following steps: Step 1: First, control the telescopic cylinder (2) to extend upward to its maximum length, driving the vertical rod (5) and suction head (8) to move upward together. Then, place the material tank to be cleaned on the top of the base (1), control the telescopic cylinder (2) to retract downward to return to its original position, driving the vertical rod (5) and suction head (8) to move downward to the inside of the material tank. According to the size of the material tank, control the two double-headed screws (19) to rotate, driving the two second sliders (20) to move towards each other, driving the two electric telescopic rods (11) to move towards each other, driving the moving plate (6) to move away from the vertical rod (5). Step 2: After moving the moving plate (6) and the cleaning mechanism to a position close to the inner wall of the material tank by using two electric telescopic rods (11), the external water supply mechanism can be controlled to deliver water to the inside of the two hollow plates (23) and spray it outward to the inner wall of the material tank through multiple nozzles (26) to wash the dirt attached to the inner wall of the material tank. At this time, the first drive motor (4) can be controlled to drive the vertical rod (5) to rotate inside the material tank, so as to drive the two cleaning mechanisms to rotate inside the material tank, so that multiple nozzles (26) can spray water evenly on the inner wall of the material tank, and the inner wall of the material tank can be washed more thoroughly. Step 3: After the rinsing work of multiple nozzles (26) is completed, continue to control the rotation of the two double-headed screws (19) or control the extension of the extension end of the two electric telescopic rods (11), so that the two first scrapers (17) set at the end of the two hollow plates (23) near the inner wall of the material tank come into contact with the inner wall of the material tank. As the first drive motor (4) drives the vertical rod (5) to continue to rotate, the two first scrapers (17) can be driven to scrape and clean the dirt on the inner wall of the material tank. After the multiple first scrapers (17) scrape the dirt on the inner wall of the material tank, control the multiple first scrapers (17) to rotate 90 degrees away from the hollow plate (23), so that the two first scrapers (17) drive the outer wall of the cleaning brush (24) to rotate to a position close to the material tank. At this time, the two cleaning brushes (24) can brush the dirt that the first scraper (17) cannot scrape off on the inner wall of the material tank at the same time as the vertical rod (5) rotates. Step 4: After cleaning the arc-shaped inner wall of the material tank, control the two second scrapers (9) to rotate downwards by 180 degrees inside the mounting base (32), so that the two second scrapers (9) rotate and extend. By controlling the extension and retraction of the telescopic cylinder (2), the two second scrapers (9) are driven to contact the bottom inner wall of the material tank. According to the size of the material tank, control the two fourth sliders (31) to move away from each other in the corresponding fourth slide groove (30), so that the two second scrapers (9) can adapt to the diameter of the bottom surface of different sized material tanks. With the help of the second drive motor (7), drive the suction head (8) and the two second scrapers (9) to rotate, so that the two second scrapers (9) can clean the dirt on the bottom surface of the material tank during the rotation of the bottom surface of the material tank, so as to achieve a comprehensive cleaning of the inner wall of the material tank.
