Description

Technical Field

[0001] The utility model relates to the technical field of exhaust gas filtering, in particular to an exhaust gas filter which is convenient for replacing a filter element. 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 refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​the enterprise. Smoke and industrial dust are discharged into the atmosphere and will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health.

[0003] When treating industrial waste gas, the filter needs to be replaced after filtering the waste gas in order to improve the filtering effect. However, the existing filter element is difficult to disassemble quickly and install again, which reduces the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0018] Compared with the prior art, the utility model provides an exhaust gas filter that is easy to replace the filter element, and has the following beneficial effects:

[0019] 1. The utility model installs the filter element into the mounting groove at the side end of the mounting frame, then installs the baffle plate at the top of the mounting frame, and presses the baffle plate downward. When the baffle plate moves downward, it drives the filter element downward, compresses the spring group, and makes the card slot and the card block at the side end of the baffle plate correspond to each other, and rotates the adjusting bolt. During the rotation of the adjusting bolt, the card block is driven to move into the card slot until the card block moves into the card slot, so that the filter element is installed in the mounting groove by using the baffle plate. Then, when the filter element needs to be replaced, it only needs to rotate the adjusting bolt to remove the card block from the card slot and remove the baffle plate. At this time, the spring group drives the filter element to move upward, and the top end of the filter element exposes the mounting groove. Then, the filter element is pulled out and the filter element can be replaced.

[0020] 2. The utility model installs a mounting frame equipped with a filter element on the side end of the filter body, starts the fan, and the fan sucks the exhaust gas into the air inlet pipe. When the exhaust gas passes through the filter cover, larger impurities are filtered outside the filter cover, and then the exhaust gas passes through the filter element, which filters it and finally discharges it through the exhaust pipe, with good filtering effect.
