Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon filter boxes, in particular to an activated carbon filter box which is convenient to maintain. Background Art

[0002] Activated carbon filter box is a purification equipment for centralized treatment of polluted gases. It is mainly used to treat waste gas and absorb odor in industrial production workshops such as pharmaceuticals, chemicals, spraying, laboratories, and printing. The activated carbon filter box arranges multiple activated carbon filters inside the box, and then concentrates the waste gas into the activated carbon filter box for overall purification and filtration, thereby achieving the purpose of centralized waste gas treatment. It is widely used.

[0003] The existing activated carbon filter box has the following disadvantages during the cleaning and maintenance process: the activated carbon filter box mainly filters and adsorbs the exhaust gas through the internal activated carbon during the exhaust gas treatment process. After a period of use, the internal activated carbon plate needs to be cleaned and replaced. During this process, the air intake of the activated carbon box needs to be stopped, and the machine can be restarted only after the maintenance is completed. For places that need to be operated continuously, the cleaning and maintenance process will affect the normal operation efficiency. For this reason, we propose an activated carbon filter box that is easy to maintain. Utility Model Content

[0007] Furthermore, it also includes a cleaning mechanism. The cleaning mechanism is arranged at the bottom of the box, and the cleaning mechanism includes a rotating shaft and a bottom plate. The rotating shaft is installed at one end of the bottom of the box and is movably connected to the bottom plate for controlling the opening and closing of the bottom of the box through the rotating shaft; the bottom of the box is connected to the bottom plate through the rotating shaft. During normal working, the bottom plate is in a closed state and does not affect the normal use of the box. When cleaning is needed, the fasteners at the end of the bottom plate can be removed, and the bottom plate can be unfolded along the rotating shaft to clean the dust and impurities accumulated on the surface of the bottom plate and inside the box.

[0008] Furthermore, an air inlet pipe and an exhaust pipe are respectively arranged at both ends of the box surface, a guide cavity connected to the air inlet pipe is opened inside the box, and the guide cavity is connected to the air inlet hole, and an exhaust cavity connected to the exhaust pipe is opened inside the box, and the exhaust cavity is connected to the exhaust hole; the guide cavity and the exhaust cavity play a role in guiding gas transportation, so that the gas to be treated and the treated gas flow along a preset route.

[0009] Furthermore, screw holes are provided at the upper and lower ends of the box body corresponding to the positions of the piston, and the box body is movably connected to a screw rod through the screw holes and is connected to the piston through the screw rod; the screw rod can be turned along the screw hole, and when the screw rod is turned, it drives the rotation of the connecting ring structure inside the piston, thereby adjusting the vertical direction of the piston.

[0010] Furthermore, corresponding mounting holes are provided at the end of the bottom plate and one end of the bottom of the box body, and rubber pads are bonded at the connection between the side and end of the bottom plate; after the bottom plate is closed, the mounting holes are aligned, and fasteners are screwed in to lock and fix the bottom plate, and the rubber pads at the connection can ensure the sealing of the connection.

Under normal use, the piston is away from the air inlet and exhaust holes, and the waste gas inside the guide cavity enters the fixed frame for treatment and is discharged from the exhaust cavity. When the activated carbon plate needs to be replaced and maintained, the screw at the corresponding position is turned so that the piston is inserted into the air inlet and exhaust holes of the corresponding section, so that the separate section can be closed. At this time, the activated carbon plate can be pulled out for cleaning and maintenance, and other sections inside the box body can still be used and operated normally during the cleaning process, which improves the convenience of maintenance of the filter box and reduces the impact on production.
