The tank body 1 is provided with a plurality of evenly distributed reinforcing ribs 11. A plurality of evenly distributed heat dissipation holes 12 are provided at the bottom end of the partition 5 and located on the inner wall of the tank body 1, and a matching protective net is provided on the heat dissipation hole 12. The rotating shaft 7 is connected to the mounting seat 6 through the middle bearing 13.

The bottom of the partition 5 and on both sides of the mounting seat 6 are provided with symmetrically arranged heat conducting sheets 16, the bottom of the heat conducting sheet 16 is provided with a semiconductor cooling sheet 17, and the top of the heat conducting sheet 16 is provided with a plurality of evenly distributed heat conducting rods 18 that penetrate the partition 5. When the tank body 1 is filled with liquid material, the motor 9 is started to drive the rotating shaft 7 to rotate, and the rotating shaft drives the propeller blades 8 to rotate to stir the liquid material. The propeller blades 8 break up the particles at the bottom of the tank body 1 during rotation to prevent them from settling at the bottom. When the temperature of the liquid material filled in the tank body 1 becomes high, the semiconductor refrigeration plate 17 can be started to cool the heat conductive plate 16, and the heat conductive plate 16 cools the liquid material through the heat conductive rod 18. By setting the rotating shaft and propeller blades, the precipitated foreign matter deposited at the bottom of the tank can be broken up and agitated to prevent precipitation inside the storage tank, which will cause trouble for subsequent cleaning. By setting a reinforcing hoop, the overall strength of the storage tank can be improved. Example

[0028] like Figure 1-6As shown, it includes a tank body 1, a discharge pipe 2 is provided on one side of the tank body 1, a valve 3 is provided on the discharge pipe 2, a feeding port 24 is provided at the top of the tank body 1, a plurality of evenly distributed reinforcing hoops 4 are sleeved on the outer wall of the tank body 1, a partition 5 is provided in the tank body 1, a mounting seat 6 is provided at the bottom end of the partition 5, a rotating shaft 7 that passes through the mounting seat 6 and the partition 5 at the top end of the mounting seat 6, a propeller blade 8 is provided at the top end of the partition 5 and located on the outer wall of the rotating shaft 7, an inner wall scraping assembly matching the tank body 1 is provided at the top end of the partition 5, a motor 9 is provided at the inner bottom end of the tank body 1, a driving end of the motor 9 is connected to the rotating shaft 7, and batteries 10 are provided at the inner bottom end of the tank body 1 and located on both sides of the motor 9. The inner wall scraping assembly includes an I-shaped frame 19 fixedly provided at the top end of the rotating shaft 7, and scrapers 20 that are symmetrically arranged and in conflict with the inner wall of the tank body 1 are provided on both sides of the I-shaped frame 19, and the scrapers 20 are connected to the I-shaped frame 19 through elastic members. The elastic member includes a plurality of evenly distributed mounting sleeves 25 respectively provided on both sides of the I-shaped frame 19, wherein the mounting sleeve 25 is provided with a slider 21 matching the I-shaped frame 19, and one side of the slider 21 is connected to the mounting sleeve 25 through a spring 22, and a connecting rod 23 extending to the outside of the mounting sleeve 25 and fixedly connected to the scraper 20 is provided on the side of the slider 21 away from the spring 22. The mounting sleeve 25 is provided with a guide slide hole matching the connecting rod 23. When the rotating shaft 7 rotates, the I-shaped frame 19 is driven to rotate at the same time, and the I-shaped frame 19 drives the scrapers 20 on both sides to scrape the inner wall of the tank body 1 to remove the particles adhered thereto. Since the scraper 20 cooperates with the spring 22 through the connecting rod 23 and the slider 21, the scraper 20 has a certain elasticity and can be in close contact with the inner wall of the tank body 1, which is convenient for scraping. By setting the inner wall scraping assembly, the inner wall of the storage tank can be scraped to prevent the particles in the liquid material from adhering to the inner wall of the storage tank, which will cause trouble for subsequent cleaning. In actual application, when the tank body 1 is filled with liquid material, the motor 9 is started to drive the rotating shaft 7 to rotate, and the rotating shaft drives the propeller blades 8 to rotate to stir the liquid material. The propeller blades 8 break up the particles at the bottom of the tank body 1 during rotation to prevent them from settling at the bottom. When the temperature of the liquid material filled in the tank body 1 becomes high, the semiconductor refrigeration sheet 17 can be started to cool the heat conductive sheet 16, and the heat conductive sheet 16 cools the liquid material through the heat conductive rod 18. By setting the rotating shaft and the propeller blades, the precipitated foreign matter deposited at the bottom of the tank can be broken up and stirred up to prevent precipitation inside the storage tank. Subsequent cleaning brings trouble, and the overall strength of the storage tank can be improved by setting a reinforcing hoop; when the rotating shaft 7 rotates, it will also drive the I-shaped frame 19 to rotate, and the I-shaped frame 19 drives the scrapers 20 on both sides to scrape the inner wall of the tank body 1 to remove the particles adhering to it. Since the scraper 20 cooperates with the extrusion spring 22 through the connecting rod 23 and the slider 21, the scraper 20 has a certain elasticity and can be in close contact with the inner wall of the tank body 1, which is convenient for scraping. By setting an inner wall scraping component, the inner wall of the storage tank can be scraped to prevent particles in the liquid material from adhering to the inner wall of the storage tank, which brings trouble to subsequent cleaning.

[0029] In summary, with the aid of the above-mentioned technical scheme of the utility model, by setting a rotating shaft and propeller blades, the precipitated foreign matter deposited on the bottom of the tank can be broken up and agitated to prevent precipitation inside the tank. By setting an inner wall scraping component, the inner wall of the tank can be scraped to prevent particles in the liquid material from adhering to the inner wall of the tank and causing trouble for subsequent cleaning. By setting a reinforcing hoop, the overall strength of the tank can be improved.
