[0002] Filter material is a general term for water treatment filter materials, which are mainly used for filtering domestic sewage, industrial sewage, pure water, and drinking water. Some filter materials are used for filtering chemical preparations, so they need to have corrosion resistance. For example, the anti-corrosion filter material for power plants with publication number CN214270239U includes a substrate, a first anti-corrosion layer is fixedly connected to the surface of the substrate, a second anti-corrosion layer is fixedly connected to the surface of the first anti-corrosion layer, and the first anti-corrosion layer includes a wood activated carbon layer. Through the coordinated use of the substrate, the first anti-corrosion layer, the second anti-corrosion layer, the wood activated carbon layer, the activated alumina layer, the purifier layer, the ion exchange resin layer, and the polyphenylene sulfide layer, the filter material can have strong corrosion resistance and improve industrial use requirements. However, the anti-corrosion filter material for power plants still has the following disadvantages during actual use:

[0003] Although the above-mentioned filter material can filter substances, after long-term use, the filtered materials are prone to adhesion, resulting in uneven distribution of the filtered materials, affecting the subsequent filtration of substances, and the cleaning or replacement of the filter material is not convenient enough. In view of the above problems, it is urgently necessary to carry out innovative design based on the original filter material. Utility Model Content

[0004] The purpose of the utility model is to provide a filter material that is resistant to chemical corrosion, so as to solve the problem proposed in the above-mentioned background technology that after long-term use, the filter material is prone to adhesion between the filtered materials, resulting in uneven distribution of the filtered materials, affecting the subsequent filtration of the substances, and it is not convenient to clean or replace the filter material.

[0005] To achieve the above object, the utility model provides the following technical solution: a filter material resistant to chemical corrosion is provided with a shell, a first filter screen is fixed at the bottom of the shell, and a second filter screen is movably provided at the top of the shell, the interior of the shell is filled with filter material, and the outer surface of the shell is evenly coated with anti-corrosion paint;

[0006] It comprises: an adjusting rod, which is movable and penetrates the interior of the second filter screen, a guide block is fixedly sleeved at the bottom of the adjusting rod, and a fixing groove is opened at the edge of the guide block;

[0007] The locking mechanism is arranged between the second filter screen and the shell, and the locking mechanism facilitates the disassembly and assembly of the second filter screen and the shell.

[0008] Preferably, elastic parts are fixed inside the shell, and the elastic parts are distributed at equal intervals, are spring-shaped, and are made of metal material. The provision of the elastic parts can ensure that the filter material is distributed more evenly inside the shell.

[0009] Preferably, the adjusting rod and the second filter screen form a rotating structure through a damping member, and the second filter screen is provided with an inner hollow, so that when the adjusting rod is rotated, the guide block can be driven to rotate synchronously.

[0010] Preferably, the fixing grooves are arranged at equal angles on the guide block, and the edge of the guide block and the end of the movable rod are fitted and slid, and the movable rod can fit and slide at the edge of the guide block when the guide block rotates.

[0011] Preferably, the locking mechanism includes a movable rod passing through the edge of the second filter screen, and the movable rod and the second filter screen are slidably connected, and a spring for returning the movable rod is wound around the outer side of the movable rod, so that the movable rod can slide on the second filter screen when it moves.

[0012] Preferably, the end of the movable rod away from the guide block is snap-connected with the limiting hole, and the limiting hole is arranged at equal angles on the top inner side of the shell, and the limiting holes and the movable rod are distributed one-to-one, and the movable rod after movement can be stuck in the limiting hole to achieve locking between the second filter screen and the shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the chemically resistant filter material can avoid uneven distribution of the filter material inside the housing, thereby ensuring its filtering effect, and when the filtering performance of the filter material decreases after long-term use, it is convenient to remove the filter material for cleaning or replacement without replacing the entire housing, so the operation is convenient. The specific contents are as follows:

[0014] 1. During the filtration of chemical agents, the chemical agents will impact the elastic parts inside the shell. The vibration of the elastic parts can drive the filter material in the shell to vibrate, which can avoid adhesion or uneven distribution. When the filter material needs to be removed, cleaned or replaced, the adjusting rod can be rotated to drive the guide block to rotate synchronously;

[0015] 2. When the guide block rotates, the end of the movable rod slides in contact with its edge, and the movable rod slides on the second filter screen after being resisted. The spring resilience can drive the movable rod to separate from the limiting hole, so that the second filter screen can be removed from the shell. After the filter material is replaced, the second filter screen is re-engaged with the shell, and then the adjusting rod is rotated to push the movable rod to move through the guide block, driving the movable rod to engage with the corresponding limiting hole, so as to ensure the stability of the second filter screen after installation, so as to facilitate the subsequent use of the filter material.
