AI Technical Summary
The filters in existing chlorinated paraffin tail gas treatment equipment are prone to clogging, leading to decreased production efficiency and increased costs.
A chlorinated paraffin exhaust gas treatment device was designed. By setting a positioning rod, a driven pipe and a scraper in the air inlet pipe, and cooperating with a compression spring, the device can periodically clean the adhering material on the lower side of the filter screen to avoid clogging.
It effectively prevents the adhering substances from clogging the air intake pipe, improves the operational stability and efficiency of the exhaust gas treatment equipment, reduces the frequency of filter replacement, and lowers production costs.

Abstract
Claims
1. Chlorinated paraffin tail gas treatment apparatus, comprising a primary filter tank (2), the lower side of which is connected to an inlet pipe (1), characterized in that: A filter screen (3) is fixedly connected to the upper opening of the air intake pipe (1), and a positioning rod (5) is fixedly connected coaxially inside the air intake pipe (1). The positioning rod (5) is fitted with a driven tube (8) on its outer side, and a scraper (7) is rotatably connected to the outer end of the driven tube (8). A compression spring I (10) is provided between the scraper (7) and the driven tube (8), and the two axial ends of the compression spring I (10) abut against the driven tube (8) and the scraper (7) respectively. The driven tube (8) is provided with a driving mechanism at one axial end. The driven tube (8) moves linearly along its central axis under the action of the driving mechanism. When the scraper (7) moves toward the side away from the air intake direction of the air intake pipe (1), the scraper (7) abuts against the filter screen (3).
2. The chlorinated paraffin tail gas treatment apparatus according to claim 1, characterized in that: The positioning rod (5) has a limiting groove (6) on its side end. A limiting rod (11) is inserted into the limiting groove (6). The limiting rod (11) is fixedly connected to the inner wall of the driven tube (8). When the driven tube (8) moves in a straight line along its central axis, the driven tube (8) rotates synchronously around its central axis.
3. The chlorinated paraffin tail gas treatment apparatus according to claim 2, characterized in that: Each of the limiting grooves (6) has a projected shape of a shuttle structure. Each limiting groove (6) includes a straight segment I (601), a straight segment II (603), and a connecting segment (602). The center line of the straight segment I (601) is parallel to the center line of the straight segment II (603). There are two connecting segments (602), which are located at the left and right ends of the straight segment I (601) and the straight segment II (603), respectively. Each connecting segment (602) smoothly transitions with the corresponding straight segment I (601) and straight segment II (603). When the limiting rod (11) is located inside the straight section I (601), the scraper (7) abuts against the filter screen (3). When the limiting rod (11) is located inside the straight section II (603), the scraper (7) does not contact the filter screen (3).
4. The chlorinated paraffin tail gas treatment apparatus according to claim 3, characterized in that: The number of scrapers (7) is multiple, and the multiple scrapers (7) are arranged equidistantly around the central axis of the driven tube (8). Furthermore, the multiple scrapers (7) together form a fan-shaped structure when projected onto the vertical plane.
5. The chlorinated paraffin tail gas treatment apparatus of claim 1, wherein: The drive mechanism includes an electric push rod (9) and a compression spring II (4). The electric push rod (9) and the compression spring II (4) are located at the two axial ends of the driven tube (8), and the movable end of the electric push rod (9) abuts against the driven tube (8), and the two axial ends of the compression spring II (4) abut against the driven tube (8) and the positioning rod (5), respectively.
