[0005] This patent has some disadvantages when used, such as: when replacing the filter element, the device needs to stop filtering and then replace it, which results in the inability to perform filtering when replacing the filter element, reducing work efficiency. In view of this, we propose a plate-type activated carbon filter. Utility Model Content

[0006] The purpose of the utility model is to provide a plate-type activated carbon filter to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a plate-type activated carbon filter, comprising:

[0008] A circular frame, wherein a sliding groove is provided in the circular frame, a sliding plate is slidably installed in the sliding groove, a rectangular groove is provided in the sliding plate, an activated carbon filter is provided in the rectangular groove, sealing gaskets are fixedly installed on both the front and rear sides of the sliding plate, a guide groove is provided on the front side of the circular frame, and a plugging plate is plugged and installed in the circular frame and at the bottom of the sliding plate;

[0009] A limiting component, which is located in the sliding plate and is used to limit the position of the activated carbon filter;

[0010] Two limit grooves, both of which are opened in the circular frame, and the two limit grooves are respectively located on the left and right sides of the sliding plate, a U-shaped block is slidably installed in the limit groove, one end of the U-shaped block passes through one side of the limit groove and extends into the sliding plate, the other end of the U-shaped block passes through one side of the limit groove and rests on the top of the sliding plate, one side of the U-shaped block and located in the limit groove is symmetrically provided with two springs.

[0011] In the present technical solution, by means of the provided plug plate, when it is necessary to replace the activated carbon filter, the personnel can first draw the plug plate out of the circular frame, at which time the plug plate can open the bottom of the sliding groove, and then the sliding plate equipped with the new activated carbon filter can be inserted into the sliding groove from top to bottom. At this time, the downward movement of the new sliding plate will squeeze the inclined surfaces of the two U-shaped blocks, so that the two U-shaped blocks move away from each other. At this time, the U-shaped block will move in the limiting groove and squeeze the two springs to shrink until one end of the U-shaped block moves out of the old sliding plate. At this time, the U-shaped block can release the limit of the old sliding plate, and the downward movement of the new sliding plate will squeeze the old sliding plate to move downward, so that the old sliding plate can be squeezed out from the bottom of the sliding groove. When the new sliding plate is completely inserted into the sliding groove, the two springs 2 in the two limit grooves will squeeze the corresponding U-shaped blocks under the rebound force, so that the two U-shaped blocks are close to each other until one end of the two U-shaped blocks are inserted into the new sliding plate. At this time, the two U-shaped blocks can limit the new sliding plate, and then the staff will insert the plug plate back into the circular frame. At this time, the plug plate can seal the bottom of the sliding groove. At the same time, during the movement of the sliding plate, under the sealing effect of the two sealing pads, it can be ensured that during the replacement of the sliding plate, the gas to be filtered will not flow out to the outside, ensuring that when the activated carbon filter is replaced, it is not necessary to shut down the equipment to be filtered, thereby improving work efficiency;

[0012] Through the setting of the limit component, the limit component can release the limit of the activated carbon filter, and the activated carbon filter can be taken out of the rectangular groove. Then the personnel can put a new activated carbon filter into the rectangular groove and squeeze the activated carbon filter to move it. When the activated carbon filter completely enters the rectangular groove, the limit component can limit the activated carbon filter to ensure that it is convenient for personnel to replace the activated carbon filter, and it can also facilitate the next use of the sliding plate.

[0013] In the above technical solution, further, the limit assembly includes:

[0014] Two through slots, both of which are opened in the sliding plate, and the two through slots are respectively located on the left and right sides of the activated carbon filter. A limit block is slidably installed in the through slot, one end of the limit block passes through one side of the through slot and extends into the activated carbon filter. Grooves are opened on the left and right sides of the sliding plate, the other end of the limit block is located in the through slot and a pull rod is fixedly installed, one end of the pull rod passes through the other side of the through slot and extends into the corresponding groove, and a spring is sleeved on the pull rod and located in the through slot.

[0015] In this technical solution, personnel can pull the two pull rods on the old sliding plate to make the two pull rods move away from each other. The movement of the pull rods will drive the limit block to move, and the movement of the limit block will squeeze the spring 1 to shrink until one end of the limit block is completely moved out of the activated carbon filter. At this time, the two limit blocks can release the limit on the activated carbon filter, and the activated carbon filter can be taken out of the rectangular groove. At this time, under the action of the rebound force of the two springs 1, the two springs 1 will squeeze the two limit blocks respectively, so that the two limit blocks are reset, and then the personnel can put the new activated carbon filter into the rectangular groove and squeeze the activated carbon filter to move it. The movement of the activated carbon filter will squeeze the inclined surfaces on the two limit blocks, causing the two limit blocks to move away from each other. The limit blocks move in the through groove and squeeze the spring one to shrink until one end of the limit block is completely entered into the through groove. When the activated carbon filter is completely entered into the rectangular groove, under the action of the rebound force of the two springs one, the two springs one will squeeze the two limit blocks respectively, causing the two limit blocks to approach each other until one end of the two limit blocks is inserted into the activated carbon filter. At this time, the two limit blocks can limit the activated carbon filter, ensuring that it is convenient for personnel to replace the activated carbon filter, and it is also convenient for the next use of the sliding plate.

[0016] In the above technical solution, further, one end of the limit block is plugged into the activated carbon filter, the pull rod is slidably connected to the through slot, the sliding plate and the groove, and the two ends of the spring are tightly welded to the limit block and the inner wall of the through slot respectively.

[0021] In the technical solution, it is ensured that one end of the U-shaped block can be inserted into the sliding plate, so that the movement of the sliding plate can squeeze the U-shaped block to move, and the structural stability of the spring 2 is ensured.

[0022] In the above technical solution, further, one of the front sides of the activated carbon filter is located in the same vertical horizontal plane as the front side of the sealing gasket, the two sides of the sealing gaskets that are away from each other are tightly fitted with the inner wall of the sliding groove, and the two sealing gaskets are slidably connected to the sliding groove.
