Description

Technical Field

[0001] The utility model relates to the technical field of plate filters, in particular to a multi-layer composite plate filter. Background Art

[0002] Plate filters are widely used in industries such as steel, electronics, chemicals, automobiles, environmental protection, and electricity, and are often used to ensure the cleanliness of the surrounding air. Patent No. CN201922489181.X discloses a plate filter. By setting a fixed frame, the fixed frame can be directly installed in the ventilation duct, which is convenient for locating the installation position of the filter. At the same time, multiple fixed frames can be fixedly connected by connecting rods, so that multiple plate filters are connected into a whole, increasing their stability during use and ensuring their filtering effect. However, when cleaning or replacing the filter plate inside the plate filter, the channel where the plate filter is located can only be closed, and then the filter plate inside the plate filter can be replaced. At this time, the channel cannot be ventilated, which is very limited and affects its use. To this end, we propose a multi-layer composite plate filter. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a multi-layer composite plate filter.

[0004] The technical solution adopted by the utility model to solve its technical problems is a multi-layer composite plate filter, comprising a body, a shell seat for auxiliary support assembled on the outer peripheral surface of the body by bolts, and multiple groups of shell seats, straight holes for ventilation are provided on the inner side of the body, and there are two groups of straight holes, both side end surfaces of the inner peripheral of the straight holes are assembled with frame seats for limiting, and a baffle for controlling opening and closing is slidably mounted on the inner side of the frame seat, a screw rod located on the inner side of the shell seat is rotatably mounted on the top surface of the baffle, and a rotary seat screwed in connection with the screw rod is rotatably mounted on the top surface of the shell seat;

[0005] The outer peripheral surface of the device is provided with concave holes for connection, and there are multiple groups of concave holes. The inner sides of the concave holes are clamped with filter plates for filtering.

[0006] By adopting the above technical solution, when the filter plate inside the plate filter needs to be cleaned, the rotary seat on the outer periphery of the shell seat at the corresponding position on the outer periphery of the device body can be rotated to make the rotary seat rotate, and the rotary seat can only rotate on its own in situ and conveniently screwed with the screw rod, so that the screw rod can pull the baffle in the corresponding straight hole on the inside of the device body, so that the baffle can move and block the corresponding straight hole on the inside of the device body. The filter plate in the straight hole here can then be disassembled, which is convenient for cleaning or replacing it. At the same time, the filter plate in the other set of straight holes on the inside of the device body can continue to filter the air inside the channel, so that the plate filter can continue to be used, thereby facilitating improving the diversity of the equipment functions.

[0007] When the filter plate needs to be disassembled, just unscrew the screws in the screw holes on the outside of the filter plate to remove the filter plate plugged into the inside of the recessed hole, making it easy to replace or clean it. The operation is simple and convenient.

[0008] Specifically, the inner peripheral surface of the concave hole is integrally constructed with a convex strip that can be used for connection, and the outer peripheral end surfaces of the filter plate are both provided with grooves that fit and connect with the convex strip.

[0009] By adopting the above technical solution, the grooves and the ridges are fitted and connected with each other, which makes it easier to improve the stability of the filter plate after installation and enables the filter plate to operate stably.

[0010] Specifically, the top surface of the filter plate and the top surface of the convex strip are both provided with screw holes for connection, and there are two groups of screw holes, and screws for fixing are screwed into the inner sides of the screw holes.

[0011] By adopting the above technical solution, the screws and the screw holes are screwed together, which makes it easy to fix the position of the filter plate clamped inside the concave hole, so that it can operate stably.

[0012] Specifically, the inner top surface of the concave hole is provided with an arc groove that can be used for connection, and there are two groups of arc grooves. The side of the filter plate that fits the concave hole is integrally constructed with an arc strip that fits and connects with the arc groove, and there are two groups of arc strips.

[0013] By adopting the above technical solution, the arc groove and the arc strip are fitted and connected with each other, which is convenient for improving the tightness of the filter plate when it is clamped on the inner side of the concave hole, and is convenient for reducing gas leakage.

[0014] Specifically, a leak-proof rubber pad is bonded to the outer peripheral surface of the arc-shaped strip.

[0015] By adopting the above technical solution, the rubber pad can easily improve the tightness of the connection between the arc strip and the arc groove, thereby further improving the tightness of the filter plate after installation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of straight holes, frame seats, baffles, shell seats, screw rods and rotary seats. When the filter plate inside the plate filter needs to be cleaned, the rotary seats on the outer periphery of the shell seats at corresponding positions on the outer periphery of the device body can be rotated to make the rotary seats rotate, and the rotary seats can only rotate in situ and conveniently screwed together with the screw rods, so that the screw rods can pull the baffles in the corresponding straight holes on the inside of the device body, so that the baffles can move and block the corresponding straight holes on the inside of the device body. The filter plates in the straight holes here can then be disassembled for easy cleaning or replacement. At the same time, the filter plates in another group of straight holes on the inside of the device body can continue to filter the air inside the channel, so that the plate filter can continue to be used, thereby facilitating the improvement of the diversity of the equipment functions.

[0018] 2. The technical solution of this application adopts the design of the concave hole and the filter plate. When the filter plate needs to be disassembled, it is only necessary to unscrew the screws in the screw holes on the outside of the filter plate to disassemble the filter plate plugged into the inside of the concave hole, making it convenient to replace or clean it, and the operation is simple and convenient.

Then the filter plate 9 in the straight hole 2 here can be disassembled, which is convenient for cleaning or replacing. At the same time, the filter plate 9 in the other group of straight holes 2 on the inner side of the device body 1 can continue to filter the air inside the channel, so that the plate filter can continue to be used, thereby facilitating the improvement of the diversity of the equipment functions.
