Description

Technical Field

[0001] This utility model relates to an automatic sewage discharge and cleaning structure for cardboard filter screens, belonging to the field of filter screen cleaning technology. Background Technology

[0002] Cardboard filters are most commonly used in program-controlled exchanges and computer room-specific constant temperature and humidity air conditioners, as well as in central fresh air units and ventilation systems; they are also used for pre-filtration of air compressors, clean room return air filtration, and pre-filtration of high-efficiency filter devices. Existing cardboard filters are mostly cylindrical or plate-shaped structures, and after long-term use, the accumulated dust causes blockages, affecting the filtration effect. Therefore, it is necessary to clean the filter screens using automatic cleaning equipment.

[0003] Existing cardboard filter screen cleaning equipment does not effectively achieve the desired cleaning results by simultaneously tapping the filter screen surface during cleaning, thus failing to loosen impurities adsorbed on the screen surface and reducing the cleanliness of the filter screen within the cleaning equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic sewage discharge and cleaning structure for cardboard filter screens, thereby solving the problems mentioned in the background art, such as the low effect of synchronous tapping on the filter screen surface during cleaning and the low effect of loosening impurities adsorbed on the filter screen surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic sewage discharge and cleaning structure for a cardboard filter screen, comprising a cleaning box, a placement plate slidably connected to the inner wall of the cleaning box, a connecting frame fixedly connected to the outer wall of the placement plate, an adjusting box slidably connected to the outer wall of the connecting frame, a connecting rod fixedly connected to the outer wall of the adjusting box, a cleaning nozzle fixedly connected to the outer wall of the connecting rod, a connecting pipe fixedly connected to the outer wall of the cleaning nozzle, a water tank fixedly connected to the outer wall of the connecting pipe via a water pump, a servo motor fixedly connected to the outer wall of the adjusting box, a rotating rod rotatably connected to the output end of the servo motor and rotatably connected to the inner wall of the adjusting box, a pulling rod rotatably connected to the outer wall of the rotating rod, and a tapping rod slidably connected to one end of the pulling rod and rotatably connected to the outer wall of the adjusting box, wherein a sliding groove is provided at the connection between the outer wall of the adjusting box and the tapping rod.

[0006] Furthermore, a recycling tank is provided at the bottom of the cleaning tank, and a filter box is provided at the bottom of the cleaning tank below the recycling tank. A return pipe is fixedly connected to the outer wall of the filter box, and a return pump is fixedly connected to one end of the return pipe and fixedly connected to the outer wall of the water tank.

[0007] Furthermore, the adjustment box moves up and down on the outer wall of the connecting frame via an electric push rod.

[0008] Furthermore, the pulling rod forms a rotating structure with the striking rod via a servo motor and a rotating rod. There are two sets of pulling rods, and the positions of the two sets of pulling rods are equidistant from the rotation center of the rotating rod.

[0009] Furthermore, the tapping rod forms a sliding structure with the pull rod and the slide groove. There are two sets of tapping rods, and the positions of the two sets of tapping rods are symmetrical about the central axis of the placement plate. The outer wall contour of the tapping rod is comb-shaped, and the filter screen to be cleaned is placed in the middle area of ​​the two sets of tapping rods.

[0010] Furthermore, the outer wall of the recycling tank has a grid-like outline.

[0011] Furthermore, the filter box is equipped with a filter screen and an activated carbon adsorption screen inside.

[0012] The beneficial effects of this utility model are as follows: Considering that the existing cardboard filter screen cleaning equipment does not have a high effect on the synchronous tapping of the filter screen surface during cleaning, and the effect on loosening the impurities adsorbed on the filter screen surface is not high, thus reducing the cleanliness of the filter screen in the cleaning equipment.

[0013] When using this invention, the filter screen is installed on the placement plate for cleaning. The cleaning nozzle is turned on, and the adjusting box is driven to reciprocate up and down along the outer wall of the connecting frame. At the same time, the servo motor is turned on, and the rotation of the rotating rod drives the pulling rod to rotate. The rotation of the pulling rod drives the beating rod to slide along the inner wall of the slide groove, achieving the effect of beating the filter screen while cleaning, thus improving the cleanliness of the filter screen in the cleaning equipment.
