[0002] The low-pressure concentration device for preparing silica sol is usually used to remove water or other solvents from the silica sol to obtain a more concentrated silica sol. This device usually needs to be able to operate at a lower pressure to ensure that there will be no excessive loss or adverse reactions during the concentration process. Generally, the pressure of the concentration tank is reduced to the required low pressure range by a vacuum pump, and then a heating rod is used to help accelerate the evaporation of the solvent, so as to ensure that the silica sol can be concentrated within a reasonable time.

[0003] In the prior art, low-pressure concentrating devices for preparing silica sols cause uneven distribution of components in the solution during concentration, resulting in higher concentrations of some components in the silica sol and lower concentrations in other places, thereby affecting the uniformity and quality of the final product.

In view of the above problems, a person skilled in the art has proposed a low-pressure concentrating device for preparing silica sol to solve the above problems. Utility Model Content

[0030] Reference Figure 1 and Figure 2 A cooling assembly is installed on the outside of the concentration tank body 1, and the cooling assembly includes a water tank 15. The water tank 15 is fixedly connected to the left end of the concentration tank body 1, and a water pump 16 is fixedly connected to the top of the water tank 15. The input end of the water pump 16 is connected to the inside of the water tank 15 through a connecting pipe, and the output end of the water pump 16 is fixedly connected to a cooling pipe 17. The cooling pipe 17 is arranged in a ring shape inside the concentration tank body 1, and a filter plate 18 is slidably connected to the inside of the water tank 15.

[0031] Specifically, the concentration tank body 1 fixes the water tank 15, so that the position of the water tank 15 is fixed. The water tank 15 fixes the water pump 16, so that the water pump 16 can operate stably. The water pump 16 is connected to the water tank 15, so that the water pump 16 can transport the coolant in the water tank 15 to the cooling pipe 17. The cooling pipe 17 is annular inside the concentration tank body 1, so that the cooling efficiency can be guaranteed. A sealing ring is provided at the connection between the water tank 15 and the filter plate 18, so that the coolant will not leak. By providing the filter plate 18, the coolant circulated back by water can be filtered, thereby ensuring the service life of the water pump 16 and the cooling pipe 17.

[0032] Reference Figure 1 , Figure 4 and Figure 6A buckle assembly is installed inside the cooling assembly, and the buckle assembly includes two limit grooves 19, which are respectively opened on the front and rear sides of the water tank 15. The inner wall of the limit groove 19 is fixedly connected with a spring 20, and the adjacent ends of the two springs 20 are fixedly connected with a limit block 21.

[0033] Specifically, the limit groove 19 and the limit block 21 fix the spring 20, so that the spring 20 can stably perform elastic deformation, the limit groove 19 limits the limit block 21 and the block 22, so that the limit block 21 and the block 22 will not deviate when moving, and the position of the filter plate 18 is fixed by the engagement of the block 22 with the slot 23.

[0034] Working principle: When it is necessary to stir the silica sol in the low-pressure concentration and scrape the inner wall of the concentration tank body 1, the motor 6 is started to operate, thereby driving the rotating rod 7 to rotate, and then driving the stirring rod 8 to stir the silica sol in the concentration tank body 1. At the same time, the connecting rod 9 is driven to rotate by the rotating rod 7, thereby driving the limiting rod 10 to rotate with it, and then driving the scraper 11 to rotate with it, so that the scraper 11 can scrape the inner wall of the concentration tank body 1;

[0035] In addition, when the concentration tank body 1 needs to be cooled, the water pump 16 is started to operate, thereby driving the coolant to flow from the water storage tank 15 to the cooling pipe 17, so that the cooling pipe 17 can cool the concentration tank body 1;

[0036] In addition, when the clogged filter plate 18 needs to be replaced and cleaned, the two pull ropes 24 are driven to move toward the adjacent end by rotating the collecting rod 25, thereby driving the front and rear limit blocks 21 to move toward the separated end, thereby squeezing the spring 20 to make elastic deformation, thereby driving the front and rear block 22 to move toward the separated end, thereby disengaging the block 22 from the slot 23, and then the filter plate 18 can be conveniently taken out for maintenance and cleaning, thereby placing the clean filter plate 18 in the water storage tank 15, and then the spring 20 is reset to move, thereby driving the front and rear limit blocks 21 to move toward the adjacent end, thereby driving the block 22 to move with it, thereby making the block 22 engage with the slot 23, thereby fixing the position of the filter plate 18.
