Abstract

The invention discloses a filter membrane clamping device with self-locking and damping functions. The filter membrane clamping device comprises a fixed seat and an air inlet seat, a suction nozzle isconnected at the lower end of the fixed seat, a lower sealing ring is arranged on the upper surface of the fixed seat, a buffer groove is formed in the upper surface of the fixed seat, the inner bottom surface of the buffer groove is connected with a limit seat through a fourth compression spring, an upper sealing ring is arranged on the lower surface of the air inlet seat, a filter membrane is mounted between the upper sealing ring and the lower sealing ring, and mounting blocks, bearings and adjusting blocks are connected on the left side and the right side of the fixed seat and sequentially distributed on the left side and the right side of the fixed seat from bottom to top. The filter membrane clamping device has self-locking and damping functions, the speed of the upper sealing ringcan approach to zero when the upper sealing contacts with the filter membrane, so that vibration can be furthest reduced when the clamping device replaces the filter membrane, and air quality and pollution sources of pollution gas are accurately evaluated.

Description

technical field [0001] The invention relates to the technical field of filter membrane clamping devices, in particular to a filter membrane clamping device with a self-locking shock-absorbing function. Background technique [0002] When detecting air or polluting gases, it is generally necessary to capture particulate matter in the air or polluting gases, so as to evaluate the air quality and pollution sources of polluting gases. In the prior art, the filter membrane method is generally used To collect particulate matter in the air or polluted gas, when using the filter membrane method to collect particulate matter in the air or polluted gas, the filter membrane needs to be installed on the filter membrane holder for use. [0003] However, the existing filter membrane clamping device does not have self-locking function and shock absorption function, which makes it easy to vibrate the filter membrane when the filter membrane is replaced by the filter membrane clamping device,...
