[0002] At present, chemical reagents, also known as biochemical reagents or test drugs, are mainly pure chemicals used to realize chemical reactions, analytical tests, research experiments, teaching experiments, and chemical formulas. They are generally divided into general reagents, high-purity reagents, analytical reagents, instrumental analysis reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion colorimetric reagents, etc.

[0003] Among them, filtering devices are often required in the production of chemical reagents, and most of the filtering devices commonly used in the market are integrated and installed on pipelines to filter the chemical reagents during pipeline transportation.

[0004] However, in this operation, since the filter channel is a one-way pipe, the filtration efficiency is limited. It is also not convenient to replace and clean the filter inside the filter device. When used twice, the filtration efficiency is limited. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0007] The quick-release filter mechanism includes a connecting cavity opened inside the material guide barrel, a branch pipe installed to connect with both sides of the top of the connecting cavity, filter covers threadedly installed on the tops of the two groups of branch pipes, three groups of equidistantly distributed rubber rings are arranged on the inner walls of the two groups of filter covers, a filter screen is fitted between two adjacent groups of rubber rings, and a material box is threadedly installed on the tops of the two groups of filter covers.

[0008] As an optional solution of the technical solution of the present application, the filter holes of the filter screen at the bottom are smaller than the filter holes of the filter screen at the top, and the top inner wall and the bottom outer wall of the filter cover are both provided with threads, and are respectively connected to the material box and the branch pipe with threads.

[0009] As an optional solution of the technical solution of the present application, a negative pressure pump is installed on the side wall of the collection box, and the negative pressure end of the negative pressure pump is connected to the other end of the negative pressure tube and installed to deliver negative pressure into the collection box.

[0010] As an optional solution of the technical solution of the present application, three groups of equidistantly distributed clamping rings are fixedly installed on the outside of the material guide barrel, and bases are fixedly installed on the bottom of the three groups of clamping rings to support the material guide barrel.

[0011] As an optional solution of the technical solution of the present application, valves are fixedly installed on the two groups of branch pipes, and knobs are installed on the outer sides of the two groups of valves to control the flow in the branch pipes.

[0012] As an optional solution of the technical solution of the present application, the tops of the two groups of material boxes are detachably installed with cover plates, the middle parts of the two groups of cover plates are provided with slots, and the two groups of slots are sleeved with filter cartridges to connect the material boxes with the outside world.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application delivers negative pressure to the inside of the collection box of the quick-release filter mechanism by driving a negative pressure pump. Since the collection box is interconnected with the connecting cavity through a suction tube, the chemical reagents inside the two groups of material boxes continuously pass through the filter cover and are slowly introduced into the collection box. This device can not only quickly filter the chemical reagents through the two groups of material boxes and introduce them into the collection box, but also, with the quick-release feature of the device, the filter screen can be easily replaced, allowing the device to repeatedly filter different chemical reagents.

In the technical solution of the present application, a cover plate is detachably installed on the top of the two groups of material boxes, and a filter cartridge is detachably installed in the middle of the cover plate. When the operator drives the negative pressure pump, negative pressure can be continuously delivered to the inside of the two groups of material boxes. With the slot opened in the middle of the cover plate, the air pressure inside the material barrel can be made the same as the external air pressure, which is convenient for the chemicals to continuously pass through the filter cover and be introduced into the collection box. At the same time, with the filter cartridge installed in the slot, dust in the external air can be filtered to avoid mixing with the chemicals and increase the difficulty of filtering the chemicals.

The top inner wall and the bottom outer wall of the filter cover 23 are threaded and are threadedly connected to the material box 33 and the branch pipe 22 respectively.

[0022] In this technical solution, negative pressure is delivered to the inside of the collection box 1 of the quick-release filter mechanism by driving the negative pressure pump 13. Since the collection box 1 is connected to the connecting cavity 21 through the suction tube 12, the chemical reagents in the two groups of material boxes 33 continuously pass through the filter cover 23 and are slowly introduced into the collection box 1. This device can not only quickly filter the chemical reagents through the two groups of material boxes 33 and introduce them into the collection box 1, but also cooperate with the quick-release feature of the device to conveniently replace the filter screen 25, so that the device can repeatedly filter different chemical reagents.

[0024] In this technical solution, when the operator is driving the negative pressure pump 13, negative pressure can be continuously delivered to the inside of the two groups of material boxes 33. By cooperating with the slot opened in the middle of the cover plate 34, the air pressure inside the material barrel can be made the same as the external air pressure, so that the chemical agents can continuously pass through the filter cover 23 and be introduced into the collection box 1.

Since the collection box 1 is connected with the connecting cavity 21 through the suction pipe 12, the chemical reagents in the two groups of material boxes 33 continuously pass through the filter cover 23 and are slowly introduced into the collection box 1. This device can not only quickly filter the chemical reagents through the two groups of material boxes 33 and introduce them into the collection box 1, but also Moreover, with the quick disassembly and assembly characteristics of the device, the filter 25 can be easily replaced, so that the device can repeatedly filter different chemical reagents.

When the operator drives the negative pressure pump 13, negative pressure can be continuously delivered to the inside of the two groups of material boxes 33. With the slot opened in the middle of the cover plate 34, the air pressure inside the material barrel can be made the same as the external air pressure, which is convenient for the chemicals to continuously pass through the filter cover 23 and be introduced into the collection box 1. At the same time, with the filter cartridge 35 installed in the slot, dust in the external air can be filtered to avoid mixing with the chemicals and increase the difficulty of filtering the chemicals.
