Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a high-pressure backflushing dust removal device. Background Technology

[0002] A plate filter is a filtration device typically used for filtering and separating liquid materials. It consists of one or more parallel plate-shaped filter screens. When liquid material passes through the filter screen, solid particles are trapped on the screen, while the liquid portion can flow out, thus achieving the purpose of filtration.

[0003] A search revealed a utility model patent with patent authorization announcement number CN204841091U, which discloses a novel plate-shaped filter, including a filter disc, an upper clamping plate, a lower clamping plate, a threaded through hole, a convenient plug connector, an upper infusion tube, a rotating screw, an infusion tube insertion hole, a support plate, an infusion tube plug, and a sealing ring. The filter disc includes an upper clamping plate and a lower clamping plate. A threaded through hole is provided on the upper side of the upper clamping plate, and a convenient plug connector is provided on the upper side of the threaded through hole.

[0004] However, when the filter components of existing filters become clogged, they need to be disassembled for cleaning, which is quite troublesome and causes excessive downtime for the equipment. Utility Model Content

The drive gear and the gear ring form a meshing transmission connection. The motor drives the drive gear to rotate, and the drive gear, through its engagement with the gear ring, drives the annular tube to rotate.

[0009] Preferably, the anti-backflow mechanism includes a conical tube fixedly connected to the inner wall of the air outlet. A support rod is fixedly connected to the inner side of the conical tube, and a hollow sleeve is fixedly connected to the end of the support rod. A sliding rod is slidably connected inside the hollow sleeve, and the sliding rod passes through the hollow sleeve. A plug is fixedly connected to the top of the sliding rod, and the plug is slidably connected to the inner side of the upper opening of the conical tube. The anti-backflow mechanism prevents air or dust from flowing back into the annular pipe through the air outlet.

[0010] Preferably, there are two support rods, and the two support rods are symmetrically distributed. The support rods provide support for the hollow sleeve.

[0011] Preferably, the plug is slidably connected to the air outlet, and the plug is made of rubber. The plug effectively seals both the conical tube and the air outlet.

[0012] Preferably, a baffle is fixedly connected to the bottom of the slide rod, and a spring is sleeved on the outer side of the slide rod. One end of the spring is fixedly connected to the baffle, and the other end of the spring is fixedly connected to the hollow sleeve. The spring force can act on the slide rod and the plug through the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a ring pipe with an air outlet below the filter plate of the filter. A sealing sleeve with a sealing bearing is installed on the side of the ring pipe and rotates relative to it. The sealing sleeve is equipped with an air supply pipe. In addition, a drive component consisting of a motor, drive gear, gear ring and fixing rod is provided below the ring pipe. This allows the air supply pipe to be connected to an air compressor through a pipeline, enabling rotational air jetting to perform high-pressure backflushing dust removal on the filter plate and prevent clogging.

[0015] 2. This utility model sets a backflow prevention mechanism inside the air outlet. When air from the ring pipe enters the air outlet, the air pressure will push the plug up, thus separating it from the air outlet. Then, when the air outlet stops, the plug will reset under the action of the spring and re-seal the air outlet, thereby preventing air or dust from flowing back into the ring pipe through the air outlet.

An air supply pipe 13 is fixedly connected to the side wall of the filter 1, and the air supply pipe 13 penetrates the filter 1, passes through the sealing sleeve 4, and enters the annular pipe 5.

[0023] Please see Figures 1-3A connecting rod 8 is fixedly connected to the bottom of the annular tube 5, and a gear ring 9 is fixedly connected to the bottom of the connecting rod 8. A support plate 10 is fixedly connected to the inner wall of the filter 1, and a motor 11 is fixedly mounted on the upper end of the support plate 10.

The motor 11 drives the drive gear 12 to rotate, and the drive gear 12, in turn, drives the annular tube 5 to rotate through its engagement with the gear ring 9.

[0024] Please see Figures 3-4 Each air outlet 6 has a backflow preventer 7 on its inner side. This backflow preventer 7 prevents air or dust from flowing back into the annular pipe 5 through the air outlet 6. The backflow preventer 7 includes a conical tube 71 fixedly connected to the inner wall of the air outlet 6. Two support rods 72 are fixedly connected to the inner side of the conical tube 71, and the two support rods 72 are symmetrically distributed.
