Problems solved by technology

[0002] The filter of the existing cement fineness negative pressure sieve analyzer usually adopts a household vacuum cleaner structure, and the lower end of the filter bag is not fixedly arranged near the motor. It is often easy to suck up the filter bag during work and burn out the motor. Manually remove the filter bag, clean and remove dust, not only the workload is heavy, but also pollute the environment. In addition, the household vacuum cleaner filter has the disadvantages of loud noise when it is working.

Description

technical field [0001] The invention belongs to the field of cement fineness detection equipment, in particular to a cement fineness negative pressure screening analysis device. Background technique [0002] The filter of the existing cement fineness negative pressure sieve analyzer usually adopts a household vacuum cleaner structure, and the lower end of the filter bag is not fixedly arranged near the motor. It is often easy to suck up the filter bag during work and burn out the motor. Manually removing the filter bag for cleaning and dust removal is not only a heavy workload, but also pollutes the environment. In addition, the household vacuum cleaner filter also has disadvantages such as high noise when it is working. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a cement fineness negative pressure sieving device, which has a reasonable structure and is safe and reliable to use. Easy to remove dust, lo...
