Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment boxes, in particular to a filter box for waste gas treatment. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and oil refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. Generally, for environmentally friendly production, most factories need to use waste gas filter boxes for filtering during processing.

[0003] The filter box in the prior art mainly uses a filter plate to filter and then discharges the filtered gas. After working for a long time, a large amount of waste gas residues will accumulate on one side of the filter plate, which will cause the filter plate to be blocked, thereby affecting the filtering effect and affecting the subsequent use. In view of the above problems, a filter box for waste gas treatment is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a filter box for waste gas treatment, which can scrape off waste gas residues adsorbed on a filter plate, thereby improving the filtering effect of the filter plate on waste gas.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a filter box for exhaust gas treatment, comprising a box body, an air inlet pipe and an exhaust device are provided on the box body, and the box body forms a cavity, characterized in that: a mounting tube is fixedly installed on one side of the cavity and the mounting tube is communicated with the air inlet pipe, and one end of the mounting tube is installed with a filter plate, the filter plate forms a spherical filter cavity, and the spherical filter cavity is communicated with the mounting tube. The bottom of the box body is fixedly installed with a collecting bottle, the bottle mouth of the collecting bottle is communicated with the spherical filter cavity, and a sliding rod that can enter and exit the spherical filter cavity is slidably arranged in the collecting bottle, and a rotating shaft is provided at one end of the sliding rod facing the spherical filter cavity, and a rotating disk is provided for axial rotation of the rotating shaft, and scraping claws facing the inner wall of the spherical filter cavity are evenly distributed on the outer peripheral wall of the rotating disk, and the rotating disk is provided with a control component for controlling the scraping claws to rotate along the rotating shaft.

[0006] By adopting the above technical scheme, the exhaust gas enters the spherical filter chamber through the air intake pipe and the mounting pipe in turn. The exhaust gas enters the spherical filter chamber and is filtered by the filter plate. The exhaust gas residue is adsorbed on the inner wall of the spherical filter chamber. The turntable is sent into the spherical filter chamber by the sliding rod. The scraper claw is used to clean the exhaust gas residue adsorbed on the inner wall of the spherical filter chamber. The control component controls the scraper claw y to rotate along the rotating shaft to scrape the exhaust gas residue adsorbed on the inner wall of the spherical filter chamber away from the inner wall of the spherical filter chamber. Then the exhaust gas residue falls into the collection bottle by its own gravity. It is easy to operate, simple in structure and low in manufacturing cost.

[0007] It is further configured that: the outer scraping contour surface formed by the rotation of the scraping claws fits with the inner wall surface of the spherical filter cavity.

[0008] By adopting the above technical solution, the outer scraping contour surface formed by the rotation of the scraper claw is arranged in contact with the inner wall surface of the spherical filter cavity, which can more effectively scrape away obstacles from the inner wall surface of the filter cavity and clean more thoroughly.

[0009] It is further configured as follows: the control component includes a driving rope connected to the turntable on one side of the rotating shaft, a connecting channel opened on the sliding rod and extending to the outside, and a reset spring connecting the turntable and the sliding rod on the other side of the rotating shaft, the reset spring resets the turntable to a vertical state with the sliding rod, and the free end of the driving rope passes through the connecting channel and extends to the outside to form a control end that is pulled downward.

[0010] By adopting the above technical scheme, the driving rope can pull the control turntable to rotate along one side of the rotating shaft, and the reset spring controls the turntable to rotate along the other side of the rotating shaft. The driving rope and the reset spring cooperate to control the reciprocating rotation of the turntable, thereby realizing the reciprocating action of several scraping claws; the control end extends to the outside to facilitate the operator's control, and the operation is simple; when the turntable is not driven by external force, the reset spring resets the turntable to a vertical state with the sliding rod, which is convenient for the operator to control the driving rope, and the structure is simple and the manufacturing cost is low.

[0011] It is further configured that: a check ring is provided at one end of the installation pipe channel facing the spherical filter cavity.

[0012] By adopting the above technical solution, during the use of the control component, the check ring is set to prevent the exhaust gas residue from easily falling from the installation pipe into the intake pipe, and it is not easy for the exhaust gas residue to reversely enter the outside from the intake pipe, thereby avoiding secondary pollution.

[0013] It is further configured as follows: a limiting ring is provided at one end of the installation tube facing the filter plate, the filter plate is formed with a mounting opening and the mounting opening is sleeved on the limiting ring, and a restraining ring is provided on one side of the limiting ring and sleeved on the mounting opening.

[0014] By adopting the above technical solution, the filter plate is passed through the limiting ring of the mounting port, and then the restraining ring is mounted on the outer ring of the mounting port, which facilitates the fixation of the filter plate, makes the filter plate less likely to shake during use, and makes it easier for the scraper claw to clean the inner wall of the spherical filter cavity stably.

[0015] It is further configured as follows: a sprayer is provided on the end surface of the rotating disk, and the spray head of the sprayer faces one side of the scraper claw.

[0016] By adopting the above technical solution, the sprayer can spray water mist, which precipitates the exhaust gas residues in the spherical filter cavity, reduces the possibility of the exhaust gas residues flying, increases the gravity of the exhaust gas residues, and makes it easier for the exhaust gas residues to fall into the collection bottle.

[0017] It is further configured as follows: an insert block is fixedly provided on the outer peripheral wall of the sliding rod, a circular limit plate is provided in the inner cavity of the collecting bottle, the limit plate has a plurality of slots arranged at intervals along the circumferential direction, and when the sliding rod rotates axially, the insert block and the corresponding slot form an insertion limit.

[0018] By adopting the above technical solution, the plug block is inserted into the corresponding slot to realize the rotation of the turntable in the spherical filter chamber, so that the scraper claw can be adjusted to other directions, and the scraper claw can be cleaned at multiple angles toward the spherical filter chamber, which effectively cleans the exhaust gas residue on the inner wall of the spherical filter chamber more thoroughly.
