[0002] Dry filter is a filtering device used to filter air or gas. Its main feature is that it does not use liquid medium in the filtering process, but relies on solid filter medium to filter solid particles, droplets or other pollutants from the airflow. This is different from wet filters, which use liquid medium in the filtering process and are usually used in occasions where solid particles, dust, smoke, droplets and other pollutants in the atmosphere need to be filtered, such as industrial production, workshop ventilation, air conditioning systems, environmental management, etc. Compared with wet filters, dry filters have the advantages of easy cleaning, low maintenance cost and wide application range, so they are widely used in many fields.

[0003] After searching, the existing Chinese patent announcement number is: CN207024866U, a dry filter that is easy to replace the filter element, including a body, the two sides of the body are respectively fixedly inlaid with an air inlet pipe and an air outlet pipe, the upper surface of the body is provided with a through groove, the interior of the through groove is respectively movably connected with a movable block and a movable frame, the lower surface of the movable block is fixedly connected to the top of the movable frame, the lower surface of the movable block is fixedly connected to a first rubber pad, the lower surface of the first rubber pad is movably connected to the inner wall of the through groove, the surface of the movable frame is movably connected to the inner wall of the body, the bottom of the movable frame is fixedly connected to a second rubber pad, the lower surface of the second rubber pad is movably connected to the bottom of the inner wall of the body, and the inner wall of the movable frame is fixedly connected to the filter element body. The utility model solves the problem that the currently used dry filter is troublesome when removing the filter element, which brings more inconvenience to the user by setting a movable block, a movable frame, a threaded rod and a knob.

[0004] In the specific implementation manner of the above patent, when the filter element body needs to be replaced, the threaded rod is rotated by holding the knob to disengage the threaded rod from the threaded hole, and then the pull ring is lifted vertically upward, and the movable block and the movable frame are pulled out of the body along the direction of the round rod to complete the disassembly and replace the new filter element body. The round hole on the movable frame is aligned with the round rod and the movable frame is inserted into the body. The threaded rod is rotated by holding the knob to screw the threaded rod into the threaded hole to complete the replacement. In this patent, when the filter element body needs to be replaced, the threaded rod is rotated by holding the knob to disengage the threaded rod from the threaded hole, and then the pull ring is lifted vertically upward, and the movable block and the movable frame are pulled out of the body along the direction of the round rod to complete the disassembly and replace the new filter element body. Align the round hole on the movable frame with the round rod and insert the movable frame into the body, hold the knob to drive the threaded rod to rotate, and screw the threaded rod into the threaded hole to complete the replacement. It is simple and convenient, and solves the problem that the dry filter currently used is troublesome when removing the filter element, which brings more inconvenience to the user.
