Technical Field
[0001] This utility model relates to the field of drum screen technology, and in particular to an activated carbon drum screen. Background Technology
[0002] An activated carbon drum screen is a mechanical device used to screen activated carbon. In the production process of activated carbon, it is necessary to separate activated carbon particles into different particle size grades according to different application requirements. The drum screen can screen out activated carbon that meets the particle size requirements according to the size of the holes on the drum. The drum screen can also remove impurities that do not meet the particle size requirements and particles that are too large or too small from the raw materials, thereby improving the overall quality of activated carbon products.
[0003] Currently, some existing rotary drum screens have an integrated screen and base structure, which makes it inconvenient to quickly replace screens with different aperture sizes. This limits the equipment's adaptability to screening activated carbon of different particle sizes, and the non-removable design makes it inconvenient to replace worn screens, increasing maintenance costs.
[0004] Therefore, those skilled in the art have provided an activated carbon drum screen to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an activated carbon drum screen. A locking block can be inserted into a second locking groove to secure the connecting block within the placement groove, quickly connecting the screen to the upper or lower cover. After the pressing block pushes the locking block into the sliding groove, the screen can be separated from the upper or lower cover, facilitating the replacement of screens with different aperture sizes for activated carbon screening. A telescopic plate can slide outwards to engage a locking plate on the upper end of the lower cover, allowing for convenient and rapid connection of multiple drum screens for activated carbon screening, thus improving work efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An activated carbon drum screen includes a screen mesh, with an upper cover and a lower cover respectively snapped onto the upper and lower ends of the screen mesh. The upper and lower ends of the screen mesh are provided with snap-fit structures inside the upper and lower covers, and splicing structures are provided on the upper and lower covers.
[0008] The snap-fit structure includes four connecting blocks, which are fixedly connected to the screen. A sliding groove is provided on one side of each connecting block, and a snap-fit block is slidably connected inside the sliding groove. Second snap-fit slots are provided inside the front and rear ends of the upper cover and both sides of the lower cover, and pressure blocks are slidably connected inside the second snap-fit slots.
[0009] The above technical solution facilitates the connection of the screen to the upper or lower cover by the setting of the connecting block, and facilitates the sliding of the screen inside the chute, being squeezed into the chute or moving in the chute and being locked into the second slot by the setting of the pressing block, and facilitates the pressing of the pressing block, so that the screen is pressed into the chute, thereby separating the connecting block from the upper or lower cover.
[0010] Furthermore, the splicing structure includes four movable columns, which are slidably connected to the upper cover. A connecting plate is fixedly connected to the lower end of each movable column, and a snap-fit plate is fixedly connected to the upper end of each movable column. Telescopic plates are slidably connected to the inside of both sides of the snap-fit plate, and a No. 1 slot is opened at each of the four corners of the outer perimeter of the lower cover.
[0011] The above technical solution allows the movable column to easily engage the snap-fit plate into the lower cover, thereby connecting the two drum screens. The telescopic plate allows the snap-fit plate to slide outwards and lock onto the lower cover, fixing the adjacent upper and lower covers.
[0012] Furthermore, a second spring telescopic rod is fixedly connected to the bottom of the slide groove, and one side of the second spring telescopic rod is fixedly connected to the locking block;
[0013] The above technical solution allows the second spring telescopic rod to move the locking block and engage it in the second slot after being compressed.
[0014] Furthermore, the front and rear ends of the upper cover and both sides of the lower cover are threaded with threaded screws, and one side of the threaded screw is fixedly connected to the pressure block;
[0015] The above technical solution allows the threaded screw to rotate and drive the pressure block to squeeze the clamping block.
[0016] Furthermore, the upper cover has placement slots at its front and rear ends and the lower cover has placement slots on both sides;
[0017] The above technical solution allows the connecting block to be inserted into the slot, thereby enabling the screen to be connected to the upper or lower cover.
[0018] Furthermore, positioning blocks are fixedly connected to both sides of the upper end of the connecting plate, and multiple positioning grooves are opened on the outer periphery of the lower end of the upper cover;
[0019] The above technical solution facilitates the fixing of the connecting plate and the top cover by setting the positioning block and positioning groove, and fixes their positions.
[0020] Furthermore, a first spring telescopic rod is fixedly connected to the front and rear ends of both sides inside the snap-fit plate, and one side of the first spring telescopic rod is fixedly connected to the telescopic plate;
[0021] The above technical solution allows the first spring telescopic rod to be set so that the telescopic plate can be moved in the opposite direction after being squeezed.
[0022] Furthermore, pull plates are slidably connected to both sides of the upper end of the snap-fit plate, and the pull plates are fixedly connected to the telescopic plate;
[0023] The above technical solution allows the pull plate to move inward when it is squeezed inward.
[0024] The present invention has the following beneficial effects:
[0025] 1. The activated carbon drum screen proposed in this utility model, compared with the existing drum screen, uses connecting blocks and locking blocks to connect the screen to the upper and lower covers. Rotating the threaded screw inward drives the pressure block to move until the locking block is squeezed into the sliding groove. Pulling the screen can separate it from the upper or lower cover. The pressure block moves in the opposite direction, and the second spring telescopic rod can drive the locking block to be locked into the second locking groove, thereby quickly fixing and separating the screen from the upper or lower cover, which is convenient for replacing screens with different apertures or wear.
[0026] 2. The activated carbon drum screen proposed in this utility model, compared with the existing drum screen, facilitates the connection of the upper and lower covers of two drum screens through the setting of the snap-fit plate. The pressing pull plate causes the telescopic plate to slide inside the snap-fit plate. The moving column drives the snap-fit plate to pass through the first snap-fit groove of the lower cover. After the pull plate is released, the first spring telescopic rod drives the telescopic plate to move, so that the snap-fit plate is locked at the upper end of the lower cover, thereby increasing the activated carbon material capacity and facilitating the screening of more activated carbon.
[0027] 3. The activated carbon drum screen proposed in this utility model, compared with the existing drum screens, can quickly connect the screen to the upper or lower cover by inserting a locking block into the second locking groove. After the pressing block squeezes the locking block into the sliding groove, the screen can be separated from the upper or lower cover, which is convenient for changing screens with different apertures to screen activated carbon. The telescopic plate can slide outward to lock the locking plate at the upper end of the lower cover, which is convenient for quickly connecting multiple drum screens to screen activated carbon and improves work efficiency.
