Description

Technical Field

[0001] This utility model relates to the field of waste gas catalytic technology, and in particular to a dry filtration device for waste gas catalytic combustion equipment. Background Technology

[0002] Dry filters must be installed in exhaust gas catalytic combustion systems. Dust, paint mist and other particulate matter (particle size ≥ 0.5 μm) in the exhaust gas will clog the micropores of the catalyst (pore size is usually 1-3 nm), resulting in a decrease in specific surface area and a reduction in catalytic efficiency of more than 50%. Dry filters can intercept more than 95% of particulate matter through F7 / F9 grade filter media.

[0003] Dry filters are highly efficient at intercepting particulate matter, but they also require frequent cleaning of the filter screen. The filter is relatively large and is tightly connected to the combustion equipment. Disassembling the internal filter screen and then reconnecting the filter to the combustion equipment is a lot of work, and the combustion equipment is shut down for too long, which affects the work efficiency. Utility Model Content

A filter screen is fitted to one outer wall of the housing, and a magnetic block is fixedly installed on the edge of the filter screen. The magnetic block is attracted and fixed to the edge of the housing. The adjustment assembly includes a movable plate, a removable plate, and a fixed plate. The fixed plate is fixedly installed at one end of the removable plate. Two movable plates are arranged and symmetrically movably installed below the housing. The two movable plates are movably connected to the removable plate. A slot is opened on the outer wall of the movable plate, and a fitting rod is fixedly installed at one end of the removable plate. The fitting rod is embedded in the slot.

[0006] Preferably, a bidirectional screw is mounted on the bottom of the housing via a bearing, a guide rod is provided on one side of the bidirectional screw, the guide rod is fixedly installed below the housing, threaded blocks are fixedly installed above the two movable plates, the two threaded blocks are symmetrically sleeved on both sides of the bidirectional screw, and one end of the movable plate is sleeved on the guide rod.

[0007] Preferably, support plates are fixedly installed at both ends of the bottom of the housing, and rollers are installed on the bottom outer walls of the support plates via bearings. A handle is fixedly installed at the end of the bidirectional screw. A threaded rod is fixedly installed at one end of the movable plate, and a sliding groove is formed through the outer wall of the movable plate. The threaded rod passes through the sliding groove of the movable plate, and a nut is provided on one side of the movable plate, which is threadedly connected to the threaded rod. A pull rod is rotatably installed on the outer wall of the housing on the side where the filter screen is not installed, and a locking block is fixedly installed on the outer wall of the housing on the side where the pull rod is engaged and fixed.

[0012] like Figure 1-4The dry filtration device for a catalytic combustion equipment for exhaust gas shown includes a housing 1 and an adjustment assembly installed below the housing 1. A filter screen 2 is fitted to one outer wall of the housing 1, and a magnetic block is fixedly installed on the edge of the filter screen 2. The magnetic block is attracted and fixed to the edge of the housing 1. The adjustment assembly includes a movable plate 9, a movable plate 6, and a fixed plate 7. The fixed plate 7 is fixedly installed at one end of the movable plate 6. Two movable plates 9 are arranged and symmetrically movable below the housing 1. The two movable plates 9 are movably connected to the movable plate 6. A slot is opened on the outer wall of the movable plate 9, and a fitting rod is fixedly installed at one end of the movable plate 6. The fitting rod is embedded in the slot.

[0013] A bidirectional screw 10 is mounted on the bottom of the housing 1 via a bearing. A guide rod 11 is provided on one side of the bidirectional screw 10. The guide rod 11 is fixedly installed below the housing 1. Threaded blocks are fixedly installed above the two movable plates 9. The two threaded blocks are symmetrically fitted on both sides of the bidirectional screw 10. One end of the movable plate 9 is fitted onto the guide rod 11.

[0014] Support plates 3 are fixedly installed at both ends of the bottom of the housing 1. Rollers 4 are installed on the bottom outer walls of the support plates 3 via bearings. A handle 5 is fixedly installed at the end of the bidirectional screw 10. A threaded rod 12 is fixedly installed at one end of the movable plate 9. A sliding groove is opened through the outer wall of the movable plate 6. The threaded rod 12 passes through the sliding groove of the movable plate 6. A nut 13 is provided on one side of the movable plate 6, and the nut 13 is threadedly connected to the threaded rod 12.

[0015] Example: Before connecting the filter housing 1 to the external combustion equipment, slide the movable plate 6 on the moving plate 9, and move the fixed plate 7 at the end of the movable plate 6 until it is flush with the base of the combustion equipment. Then, turn the handle 5, and the double-ended screw 10 will drive both moving plates 9 to move simultaneously. The guide rod 11 acts as a guide, allowing the fixed plate 7 to fit against the base of the combustion equipment. Then, use bolts to fix the fixed plate 7 to the base, and then tighten the nut 13 on the threaded rod 12 to fix the movable plate 6 on the moving plate 9.
