For example, the application No. CN201811608693.7 discloses an automatic liquid discharge device of a vacuum ceramic filter, which is characterized in that a vacuum tank is provided with a liquid level sensor and a liquid level pipe to realize automatic discharge. The innovation point is on the liquid level sensor. Also like the "ceramic filter automatic drainage device" with application number CN201821325668.3, the key point is to uniformly vacuumize and separate the liquid storage bins, and also to set a water level observation tube, which is innovative in the separation of the liquid storage bins.
When the existing ceramic filter is started, filtrate flows into a vacuum barrel through ceramic plate micropores and a distribution valve under the condition of negative pressure, and the filtrate in the vacuum is discharged out through a filtrate pump. Because the pressure in vacuum is generally-0.092 MPa, in order to compensate the cavitation allowance of the filtrate pump, the height difference requirement of 2.5-3.5 meters is required between the filtrate pump and the vacuum barrel, and certain requirement is required for the use height, which is often a difficult problem. In addition, the reliability of the control by water level sensing is not the best mode, the damage rate is very high, and the stability of the production efficiency is directly influenced.
Aiming at the existing problems, technicians of the company explore the technical innovation, and finally obtain the technical scheme through continuous efforts, and the technical scheme is industrially applied in practice.
