Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas filtering, and specifically relates to a composite tail gas filtering device. Background Art

[0002] Exhaust gas is a waste gas generated during the operation of a machine or other equipment. It is a major factor in air pollution. Before the exhaust gas is discharged, a filtering device is needed to treat the exhaust gas to reduce air pollution.

[0003] The Chinese patent application number CN202221665288.0 discloses a vertical kettle exhaust gas filtering device, comprising: a vertical kettle body, a side wall of one side having an exhaust gas outlet pipe fixedly arranged at a central symmetrical position, the exhaust gas outlet pipe being a hollow cylindrical structure; a fixed plate, which is plugged into the interior of the trough, and the fixed plate is located directly below the exhaust gas outlet pipe; a fixed block, which is fixedly arranged on one side wall of the fixed plate; the beneficial effect is that the exhaust gas generated inside the vertical kettle body enters the interior of the exhaust gas purification box through the exhaust gas outlet pipe, and is discharged after being filtered by three sets of filter screens. When the filter screen needs to be cleaned, the pull rods on both sides of the connecting plate are pulled outward, and the pull rods drive the limit blocks to move. When the limit blocks no longer limit the connecting plate, the fixed plate pops up from the inside of the exhaust gas purification box, and the filter screen can be cleaned after popping up, and the sealing groove is clamped into the interior of the first sealing gasket, and the second sealing gasket is clamped on the outer side wall of the fixed plate to prevent exhaust gas leakage. However, when the above device is actually used, the pull rod is pulled to drive the limit block to move to release the fixation of the connecting plate. After the fixation of the connecting plate is released, the first return spring will drive the fixing plate and the filter to pop out. At this time, the staff pulls the two pull rods with both hands respectively, which is inconvenient to take the fixing plate. Moreover, the staff is located right in front of the exhaust purification box, and it is quite dangerous for the fixing plate to pop out directly.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0028] Limiting grooves 6 are provided on both sides of the inner wall of the slide groove 3, and limiting rods 7 are elastically matched on both sides of the moving frame 4. The two limiting rods 7 are respectively matched with the two limiting grooves 6. Two first springs 8 are provided on the side of the moving frame 4 away from the sealing block 9, and the first springs 8 are matched with the exhaust gas purification box 1.

[0029] The application of one aspect of this embodiment is as follows: when in use, the external equipment is connected through the exhaust gas connecting pipe 2, and the exhaust gas is discharged into the exhaust gas purification box 1 through the exhaust gas connecting pipe 2. The exhaust gas passes through the filter screen 5 from the exhaust gas purification box 1 to be filtered. When the filter screen 5 needs to be cleaned after long-term use, the movable frame 4 is pressed to release the fixing of the limiting groove 6 on the limiting rod 7, and then the first spring 8 squeezes the movable frame 4 out of the slide groove 3, and the movable frame 4 and the filter screen 5 can be taken out. After cleaning the filter screen, the movable frame 4 is moved into the slide groove 3 again. During the process of the movable frame 4 entering the slide groove 3, the limiting rod 7 enters the limiting groove 6, and then the first spring 8 squeezes the movable frame 4 to drive the limiting rod 7, and the squeezed limiting rod 7 is fixed by the limiting groove 6, completing the installation of the movable frame 4 and the filter screen 5.

[0030] By setting the limit groove 6, the limit rod 7 can enter the limit groove 6 for fixation during the process of the moving frame 4 entering the slide groove 3. When the moving frame 4 needs to be moved out, the moving frame 4 can be pressed to release the fixation of the limit groove 6 on the limit rod 7, thereby facilitating the placement or removal of the moving frame 4 and the filter screen 5 and reducing the situation where the moving frame 4 pops out directly. By setting the first spring 8, after the limit rod 7 enters the limit groove 6, the first spring 8 can squeeze the moving frame 4 to drive the limit rod 7, and the squeezed limit rod 7 is fixed by the limit groove 6, which is convenient for installing the moving frame 4 and the filter screen 5.
