Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, and in particular relates to a suspended dust filter fan. Background Technology

[0002] Dust filter fans are devices used to purify dust-laden gases. They separate solid dust from the gas using specific filter materials. The main types are bag filters and cartridge filters. Cartridge filters are classified according to their installation method as inclined, side-mounted, suspended, and top-mounted.

[0003] In the patent publication (announcement) number: CN214437463U, titled "A Suspended Filter Cartridge Dust Collector," the suspended installation method typically involves installing a hanger inside the filter cartridge. One end of the hanger is fixed relative to the bottom of the filter cartridge, and the other end is fixed to the air outlet of the tube sheet. A cross is erected at the air outlet of the tube sheet to hang the hanger, thereby fixing the filter cartridge to the dust collector housing. When installing the filter cartridge, the hanger must first be fixed to the filter cartridge, and then the hanger is installed in the corresponding position on the housing. When disassembling the filter cartridge, the hanger must first be removed to release the space restriction on the movement of the filter cartridge before the filter cartridge can be removed from the housing. The operation process is relatively cumbersome. Utility Model Content

[0004] The technical problem this invention aims to solve is that the installation and disassembly of the filter cartridge is a rather cumbersome process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a suspended dust filter fan, comprising a housing, a door, supporting legs, an inlet pipe, and an exhaust pipe. The door is hinged to the housing, the supporting legs are fixedly connected to the bottom of the housing and are symmetrically distributed from left to right, the inlet pipe is fixedly connected to the bottom of one side of the housing, and the exhaust pipe is fixedly connected to the top of the housing. Both the inlet pipe and the exhaust pipe communicate with the interior of the housing.

[0006] The suspended filter assembly is located inside the housing and is used for quick removal and suspension of the filter elements.

[0007] Furthermore, the suspended filter assembly includes a partition, a top ring, a sealing ring, a filter cartridge, and an outer cylinder, wherein:

[0008] The partition is fixedly connected between the inner walls of the box. The partition has through holes, which are symmetrically distributed in pairs. The top ring is fixedly connected to the bottom of the partition and is located below the through holes. The sealing ring is fixedly connected to the bottom wall of the partition and is symmetrically distributed in pairs. The sealing ring is located on the outer wall of the top ring. The outer cylinder is fixedly connected to the outer wall of the filter cartridge and is threaded to the outer wall of the top ring. The outer wall of the filter cartridge and the inner wall of the top ring are in contact. The top wall of the outer cylinder is located directly below the sealing ring.

[0009] Furthermore, the suspended filter assembly also includes a servo motor, a cylinder, an adjusting cylinder, a base plate, a base support plate, and a limiting rod, wherein:

[0010] The servo motor is fixedly installed at the bottom of the housing. The cylinder is located at the bottom of the housing and fixedly installed at the output end of the servo motor. The adjusting cylinder is threadedly connected to the upper end of the cylinder. The base plate is fixedly connected to the upper end of the adjusting cylinder. The bottom support plate is fixedly connected to the top of the base plate and they are symmetrically distributed in pairs. The limiting rod is fixedly connected to the outer wall of the base plate and they are symmetrically distributed in pairs. The inner wall of the housing is provided with a limiting groove, and the limiting block is slidably disposed inside the limiting groove.

[0011] Furthermore, the bottom wall of the partition is provided with guide rods, which are evenly distributed. Limiting blocks are fixedly connected to the guide rods. A ring is rotatably connected to the outer wall of the filter cartridge. The guide rods vertically pass through the ring and are slidably connected to it.

[0012] Furthermore, the top wall of the base plate is provided with a support plate, which is arranged in a 7-shape and vertically passes through the lower end of the guide rod and is slidably connected to it.

[0013] Furthermore, a gas collection hood is provided between the top wall of the partition and the top wall of the box, and the inner diameter of the hood decreases from bottom to top. The gas collection hood is connected to the exhaust pipe, and the exhaust pipe is equipped with a valve. All the through holes are located inside the gas collection hood.

[0014] Furthermore, the limiting block is located above the circular ring, and the bottom support plate is adapted to the lower end of the filter cylinder.

[0015] The beneficial effects of this utility model after adopting the above structure are as follows:

[0016] (1) When installing the filter cartridge, open the box door, insert the ring into the guide rod, and then screw the filter cartridge onto the outer wall of the top ring through the outer cylinder until the top of the outer cylinder is in contact with the sealing ring. At this time, the filter cartridge can be pre-installed. Then turn on the servo motor. The rotation of the cylinder causes the adjusting cylinder and the bottom plate to move upward under the limiting and guiding action of the limiting rod and the limiting groove until the support plate is inserted into the guide rod and the bottom wall of the bottom support plate contacts the lower end of the filter cartridge. At this time, the ring is between the limiting block and the support plate, which can ensure the stability of the filter cartridge during installation and use.

[0017] (2) During use, dust enters through the air inlet pipe and is filtered by each filter cartridge. The filtered air is concentrated in the air collection hood by the action of the through holes. The gas can be discharged by opening the valve. The filtered impurities will be concentrated at the bottom of the box. A partition can be added to the outer wall of the cylinder for dust collection.
