DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] Please refer to the attached Figure 1 -attached Figure 5 -and attached Figure 6 And on the basis of Embodiment 1, it is further obtained that the stirring device 5 includes a rotating motor 501. The output end of the rotating motor 501 is fixedly connected to a rotating rod 502. A plurality of uniformly distributed stirring rods 503 are fixedly installed on the circumferential surface of the rotating rod 502. A sliding sleeve 504 is slidably connected to the surface of each of the plurality of stirring rods 503. A telescopic spring 505 is fixedly connected between the rotating rod 502 and the sliding sleeve 504. A limiting block 508 is fixedly connected to one end of each of the plurality of stirring rods 503 away from the rotating rod 502. The telescopic spring 505 is slidably connected to the outer surface of the stirring rod 503. A connecting rod 506 is fixedly connected to the bottom of the sliding sleeve 504. One end of the connecting rod 506 away from the sliding sleeve 504 is fixedly connected to a stirring plate 507. The limiting block 508 does not contact the inner wall of the tank body 3.

[0024] When the rotating rod 502 rotates, the telescopic spring 505 will be stretched due to the centrifugal force, so that the position of the stirring plate 507 can be adjusted to expand the stirring range. The function of the limiting block 508 is to prevent the sliding sleeve 504 from falling off the surface of the stirring rod 503.

[0025] Specifically, the rotating motor 501 drives the rotating rod 502 and the stirring rods 503 to rotate. During the rotation of the stirring rods 503, the sliding sleeve 504 will move away from the rotating rod 502 due to the centrifugal force. At this time, the lengths of the telescopic springs 505 pulled by each sliding sleeve 504 are different, and due to the different rotation speeds of the rotating rod 502, the positions of the sliding sleeve 504 on the stirring rod 503 are also different, so that the stirring plate 507 can fully stir the slurry in the tank body 3 at different horizontal positions, improving the stirring effect and preventing component precipitation and uneven distribution.

[0026] Embodiment 2:

[0027] Please refer to the attached Figure 1 -attached Figure 4, An electronic paste storage tank with a constant viscosity, including a fixing frame 1 and a temperature control device 4. Inside the fixing frame 1, there is a fixed connection with a housing 2. Inside the housing 2, there is a tank body 3. The temperature control device 4 includes a water tank 401 and a circulation pump 402. There is a water outlet pipe 406 fixedly installed between the water tank 401 and the circulation pump 402. The output end of the circulation pump 402 is fixedly installed with a spiral pipe 405. One end of the spiral pipe 405 away from the circulation pump 402 is fixedly connected with a return pipe 404. Inside the inner wall of the water tank 401, there is a heating coil 408. On the inner bottom surface of the water tank 401, there is a temperature sensor 407. On the front outer surface of the water tank 401, there is a temperature display controller 403. At the top of the housing 2 and the tank body 3, there is a sealed top cover 6. Inside the tank body 3, there is a stirring device 5. One end of the water outlet pipe 406 extends into the interior of the water tank 401, and the other end is fixedly connected to the input end of the circulation pump 402. Both the water tank 401 and the circulation pump 402 are fixedly installed on the bottom surface of the fixing frame 1. The spiral pipe 405 is arranged inside the housing 2 and is fixedly connected to the outer wall of the tank body 3. Both the spiral pipe 405 and the return pipe 404 penetrate through the housing 2. One end of the return pipe 404 away from the spiral pipe 405 extends into the interior of the water tank 401. The temperature sensor 407 is signal-connected to the temperature display controller 403, and the heating coil 408 is electrically connected to the temperature display controller 403.

[0028] The temperature sensor 407 monitors the internal temperature of the water tank 401 in real time, and at the same time, the water temperature will be displayed on the temperature display controller 403, which is easy to control the water temperature in the water tank 401 to be in a constant state. The sealed top cover 6 is locked with fixing bolts, which is convenient for disassembly and installation, and the sealed top cover 6 has good sealing performance to prevent external air and moisture from entering the tank body 3, ensuring that the chemical stability and viscosity of the paste are not affected by the external environment.

[0029] Specifically, the temperature display controller 403 controls the heating coil 408 to heat the water in the water tank 401 to an appropriate temperature, starts the circulation pump 402, and the water in the water tank 401 sequentially enters the water outlet pipe 406, the spiral pipe 405 and the return pipe 404, and so on in a cycle. While cooperating with the simultaneous operation of the stirring device 5, the paste in the tank body 3 is always at a constant temperature, avoiding the influence of too high or too low temperature on the viscosity of the paste.

[0030] Working principle of the present utility model: The present utility model is an electronic slurry storage tank capable of maintaining a constant viscosity. First, the slurry is injected into the tank body 3 and sealed by the sealing top cover 6. The temperature display controller 403 controls the heating coil 408 to heat the water in the water tank 401 to an appropriate temperature. Then, the circulation pump 402 is started, and the water in the water tank 401 enters the water outlet pipe 406, the spiral pipe 405, and the return pipe 404 in sequence, and circulates in this way. At the same time, the rotating motor 501 drives the rotating rod 502 and the stirring rod 503 to rotate. During the rotation of the stirring rod 503, the sliding sleeve 504 will move away from the rotating rod 502 due to centrifugal force. At this time, the lengths of the telescopic springs 505 pulled by each sliding sleeve 504 are different, and due to the different rotation speeds of the rotating rod 502, the positions of the sliding sleeves 504 on the stirring rod 503 are also different, so that the stirring plate 507 can fully stir the slurry in the tank body 3 at different horizontal positions, making the slurry in the tank body 3 always at a constant temperature, avoiding the influence of too high or too low temperature on the viscosity of the slurry, and at the same time avoiding the precipitation and uneven distribution of the slurry components.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
