Cement fineness negative pressure sieve analysis apparatus

Abstract

The present invention discloses a cement fineness negative pressure sieve analysis apparatus comprising a test sieve, a sieve seat, a jet nozzle, a straw, a support, a micro-motor, a cyclone and a filter, the filter comprises a housing, a motor, a filter bag and a dust hopper, the motor, the filter bag and the dust hopper are arranged in the housing, a connection plate is arranged between the motor and the filter bag, the connection plate is provided with one or more connecting holes, and the filter bag is located below the connecting holes; a vibration rack is arranged between the dust hopper and the filter bag, and the vibration rack is driven by a vibrating driving device, and is in transmission connection with the filter bag; a sealing door includes a door frame body, a sealing door plate arranged on the inner side of the door frame body, an elastic member arranged between the door frame body and the sealing door plate, and a seal ring connected with the inner wall of the housing. The cement fineness negative pressure sieve analysis apparatus is reasonable in structure, safe and reliable to use, easy to deash, low in noise, and good in sealing effect.

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...
