[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4This utility model provides a self-cleaning plaster preparation stirring device, including a tank 1, which is divided into a vertical section and a conical bottom. The top of the tank 1 is open, and a three-section lid 2 is bolted to the top of the tank 1. A stirring frame 5 is rotatably connected to the lower surface of the three-section lid 2 via a bearing seat, and the top of the stirring frame 5 passes through the three-section lid 2. A motor base 3 is bolted to the upper surface of the three-section lid 2, and a mechanism for rotating the stirring frame 5 axially is bolted to the motor base 3. The drive motor 4 and the stirring rack 5 are equipped with scraper assemblies for scraping off the plaster on the vertical and conical side walls of the tank 1. The upper surface of the three-section can lid 2 is fixedly connected with two symmetrical sets of nozzles 6 by bolts. The bottom end of the nozzles 6 passes through the three-section can lid 2. The top of each set of nozzles 6 is welded with a bent pipe 7 that communicates with each set of nozzles 6. The upper surface of the three-section can lid 2 is fixedly connected with two connectors 8 by pipe racks. The two connectors 8 are respectively connected to the two bent pipes 7 by connecting pipes 9, which are rubber hoses.

[0024] It should be noted that the drive motor 4 is existing technology, which is a servo motor with an encoder. The number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0025] By using the side wall scraper 11 and the conical wall scraper 14 in conjunction with two sets of spray nozzles 6, the tank 1 is automatically sprayed and cleaned after production. The rotating side wall scraper 11 and the conical wall scraper 14 work together with the sprayed cleaning liquid, combining mechanical scraping with water flushing, which can quickly and thoroughly remove the residue from the tank 1, greatly reducing the workload and time of traditional manual cleaning, and improving production efficiency and hygiene standards.

[0026] After a batch of plaster is prepared, the tank 1 needs to be cleaned. The cleaning fluid source is connected to the connector 8 fixed on the three-section tank cover 2 through an external pipe. The cleaning fluid is sprayed out from two sets of symmetrically distributed nozzles 6 through the connecting pipe 9 and the bend 7 made of rubber hose. Since the bottom of the nozzle 6 is bent towards the side wall of the tank 1 and its nozzle is fan-shaped and can rotate, the spray coverage of the cleaning fluid can be expanded to form a spray covering most of the area of ​​the tank 1.

[0027] During the cleaning process, the drive motor 4 can be restarted at a low speed to drive the stirring rack 5, side wall scraper 11, and conical wall scraper 14 to rotate slowly. The rotating scraper can scrape off the solidified plaster residue from the tank wall. At the same time, the cleaning liquid sprayed from the nozzle 6 directly washes the scraped residue and the surface of the tank wall, realizing the synergistic effect of mechanical scraping and water rinsing, which greatly improves the cleaning efficiency and cleanliness. Compressed air or steam can also be introduced into the tank 1 through the air inlet 16 on the clearance hole 15 to further enhance the cleaning effect or to carry out rapid drying.

[0028] Furthermore, the three-section can lid 2 is divided into three sections. The middle section is fixed to the top of the can body 1, and the two side sections located in the middle section are hinged to the middle section. Both side sections can be lifted.

[0029] The three-section tank lid 2, with its two sides that can be lifted, greatly facilitates operators to inspect the cleanliness of the tank 1 or perform necessary manual cleaning, making equipment maintenance more convenient and thorough.

[0030] In this utility model, the scraper assembly includes multiple support rods 10 fixedly connected to the outer circumference of the main shaft of the stirring frame 5 by bolts. The multiple support rods 10 are divided into two groups, and one end of each group of support rods 10 is fixedly connected to a side wall scraper 11 by bolts. An extension rod 12 is fixedly connected to the bottom end of the main shaft of the stirring frame 5 by bolts. Two groups of support rods 13 are welded in a ring array on the outer circumference of the extension rod 12. One end of each group of support rods 13 is fixedly connected to a conical wall scraper 14 by bolts. The two side wall scrapers 11 are arranged in a ring array. Both support rods 10 and support rods 13 are telescopic structures, and their telescopic extension is fixed by locking bolts.

[0031] Stirring and scraping: Start the drive motor 4 fixed on the motor base 3. The motor output shaft drives the stirring frame 5 connected to it to rotate axially. When the stirring frame 5 rotates, it drives multiple sets of support rods 10 and 13 fixed on its main shaft to rotate synchronously. The side wall scraper 11 at the end of the support rod 10 revolves with the stirring frame 5. Its arc-shaped blade is always in contact with the inner wall of the vertical part of the tank 1. While stirring the paste, it can efficiently scrape off the paste adhering to the vertical wall, prevent the material from sticking to the wall and charring, and ensure that there are no dead corners in the stirring and that the heat transfer is uniform.

[0032] Furthermore, both side wall scrapers 11 and both conical wall scrapers 14 are arc-shaped, and both side wall scrapers 11 and both conical wall scrapers 14 are arranged in a circular array. The two side wall scrapers 11 and the two conical wall scrapers 14 are respectively attached to the inner wall of the vertical part of the tank body 1 and the inner wall of the conical bottom.

[0033] In this utility model, the three-section can lid 2 is provided with a through-hole 15, and each of the two through-holes 15 is provided with an air inlet 16 for filling the can body 1 with gas.

[0034] The enclosed tank 1 structure and integrated cleaning and air intake design reduce the risk of external contaminants entering during the production process. Gas can be introduced through the air intake head 16 to create a pressure difference, thereby accelerating the discharge of the plaster. The tank 1 can also be dried after cleaning to prevent bacterial growth.

[0035] At the same time, the extension rod 12 at the bottom of the mixing rack 5 drives the conical scraper 14 at the end of the support rod 13 to rotate. Its arc design is also in close contact with the inner wall of the conical bottom of the tank 1, scraping up the plaster accumulated at the bottom of the conical bottom and participating in the mixing, ensuring that the material can be fully mixed and discharged smoothly from the bottom outlet. In the process of discharging, inert gas is injected into the tank 1 through the air inlet 16 to increase the air pressure in the tank 1, thereby squeezing the plaster in the tank 1 and accelerating the discharge speed of the material.

[0036] In this invention, the nozzle 6 is located below the three-section can lid 2 and bends towards the side wall of the can body 1. The bottom bend of the nozzle 6 is a rotatable structure and its nozzle is fan-shaped.

[0037] The use of this utility model involves the following steps:

[0038] S1: Stirring and scraping. Start the drive motor 4 fixed on the motor base 3. The motor output shaft drives the stirring frame 5 connected to it to rotate axially. When the stirring frame 5 rotates, it drives multiple sets of support rods 10 and support rods 13 fixed on its main shaft to rotate synchronously. The side wall scraper 11 at the end of the support rod 10 revolves with the stirring frame 5. Its arc-shaped blade is always in contact with the inner wall of the vertical part of the tank 1. While stirring the paste, it can efficiently scrape off the paste attached to the vertical wall, prevent the material from sticking to the wall and charring, and ensure that there are no dead corners in the stirring and that the heat transfer is uniform.

[0039] S2: At the same time, the extension rod 12 at the bottom of the mixing rack 5 drives the conical scraper 14 at the end of the support rod 2 13 to rotate. Its arc design is also in close contact with the inner wall of the conical bottom of the tank 1, scraping up the plaster accumulated at the bottom of the conical bottom and participating in the mixing, ensuring that the material can be fully mixed and discharged smoothly from the bottom outlet. In the process of discharging, inert gas is injected into the tank 1 through the air inlet 16 to increase the air pressure in the tank 1, thereby squeezing the plaster in the tank 1 and accelerating the discharge speed of the material.

[0040] S3: After a batch of plaster preparation is completed, the tank 1 needs to be cleaned. The cleaning liquid source is connected to the connector 8 fixed on the three-section tank cover 2 through an external pipe. The cleaning liquid is sprayed out from two sets of symmetrically distributed nozzles 6 through the connecting pipe 9 and the bend 7 made of rubber hose. Since the bottom end of the nozzle 6 is bent towards the side wall of the tank and its nozzle is fan-shaped and can rotate, the spray coverage of the cleaning liquid can be expanded to form a spray covering most of the area inside the tank 1.

[0041] S4: During the cleaning process, the drive motor 4 can be restarted at a low speed to drive the stirring rack 5, side wall scraper 11, and conical wall scraper 14 to rotate slowly. The rotating scraper can scrape off the solidified plaster residue from the tank wall. At the same time, the cleaning liquid sprayed from the nozzle 6 directly washes the scraped residue and the surface of the tank wall, realizing the synergistic effect of mechanical scraping and water rinsing, which greatly improves the cleaning efficiency and cleanliness. Compressed air or steam can also be introduced into the tank 1 through the air inlet 16 on the clearance hole 15 to further enhance the cleaning effect or to carry out rapid drying.

[0042] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
