The following mainly introduces the working principle and process.

[0020] When the current filtration device for chemical reagent production is in use, it cannot collect and process the filtered impurities during filtration. This causes the impurities to accumulate above the filter screen, resulting in a risk of blockage of the filter screen. Once blocked, it will affect the overall filtration efficiency and even make it impossible to carry out the filtration work, thus bringing inconvenience to the use of the staff.

[0021] In view of this, the present utility model provides a chemical reagent filtration device. Through the cooperation of a tank body, a stirring mechanism, and a collection and filtration mechanism, it can automatically collect the filtered impurities when filtering materials, thereby avoiding the phenomenon of blockage of the filter screen. At the same time, it also brings convenience to the subsequent cleaning process of the staff. Therefore, it can greatly improve the overall work efficiency, ensure the filtration quality, and facilitate the use of the staff.

A feed hopper 5 is installed on one side of the top of the tank body 1. A discharge pipe 6 is installed below one side of the tank body 1 close to the feed hopper 5. The chemical reagent filtration device further includes: a stirring mechanism 2, arranged above the tank body 1; a collection and filtration mechanism 3, installed inside the tank body 1; an auxiliary mechanism 4, arranged above the collection and filtration mechanism 3.

[0026] In the specific implementation process, it is particularly worth noting that the servo motor 201 can provide power for the vertical rod 202 and the stirring rod 203, so that the stirring rod 203 can stir the materials to avoid the phenomenon of accumulation of filtered impurities.

[0027] Specifically, on the basis of the above-mentioned Embodiment 1, when filtering, the staff turns on the external power supply of the servo motor 201. At this time, the servo motor 201 drives the vertical rod 202 to rotate, and the vertical rod 202 drives the stirring rod 203 to rotate. Then, as the stirring rod 203 rotates, the materials can be stirred.

[0029] In the specific implementation process, it is particularly worth noting that the first filter screen 302 and the second filter screen 305 can filter and block impurities, and the collection box 304 can collect the filtered impurities, thereby avoiding clogging of the first filter screen 302 by impurities and ensuring the filtering quality of the chemical reagent filtering device;

[0030] Furthermore, a sealing gasket is installed at the connection gap between the cover plate 303 and the tank body 1, and a clamping block is installed at the bottom of the concave box 301 and is movably connected to the top groove of the collection box 304;

[0031] In the specific implementation process, it is particularly worth noting that the sealing gasket can improve the sealing performance between the cover plate 303 and the tank body 1, thereby avoiding the phenomenon of material leakage. At the same time, the material of the sealing gasket is not limited as long as it meets the use requirements. The clamping block can improve the connection stability between the collection box 304 and the concave box 301;

[0032] Specifically, on the basis of the above-mentioned Embodiment 1 and Embodiment 2, when the material enters the inside of the concave box 301, it can be filtered through the first filter screen 302. At the same time, the stirring mechanism 2 can scrape the filtered impurities into the inside of the collection box 304, and at this time, the filtering and collection work can be automatically completed.

[0033] Embodiment 4: From Figure 1 、 2 and 3, it can be seen that the auxiliary mechanism 4 includes: a gas supply device 401, and the specific equipment selection of the gas supply device 401 can be determined according to actual use requirements and will not be elaborated here as long as it meets the use requirements.

Two are provided and are respectively detachably connected to the bottoms of the two connecting rods 405; a temperature sensor 407, the model of the temperature sensor 407 is not specifically limited as long as it meets the use requirements. It is arranged inside the tank body 1 and is detachably connected to the upper side of one side of the concave box 301; among them, the gas supply device 401 can draw external air into the inside of the tank body 1, thereby improving the filtering efficiency by increasing the pressure, and the heating rods 406 can change the internal environment of the tank body 1;

[0034] In the specific implementation process, it is particularly worth noting that the temperature sensor 407 should be well sealed, and the specific method is not limited as long as it meets the usage requirements.

The one-way valve 402 can prevent the reverse flow of gas inside the tank body 1, and the pressure gauge 403 can monitor the pressure inside the tank body 1 in real time, so that the staff can handle it more conveniently.

[0035] Specifically, based on the above-mentioned Embodiment 1, Embodiment 2 and Embodiment 3, when it is necessary to change the temperature inside the tank body 1, the staff turns on the external power supply of the heating rod 406. At this time, the heating rod 406 can heat the interior of the tank body 1. When the temperature reaches the set value of the temperature sensor 407, the temperature sensor 407 can send the monitoring signal to the controller 404, and then the controller 404 turns off the heating rod 406. When it is necessary to improve the filtration efficiency, the staff turns on the external power supply of the air supply device 401. At this time, the air supply device 401 can draw external air into the interior of the tank body 1.
