- Q:What is the reason that the ceramic filter does not absorb mineral powder?
- The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
- Q:Can the ceramic plate filter the hot air?
- The vacuum degree of the ceramic filter in the vacuum system is about -0.085MPa. If the abnormal vacuum is found, the normal vacuum suction will not be available, and the suction effect will be poor, even without suction. If the vacuum is abnormal, should adhere to the vacuum pump, vacuum connection pipe is whether the fault Water Leakage leakage, distribution valve friction sealing, ceramic filter plate is connected with the rubber tube is aging or exfoliation, ceramic filter plate rupture.
- Q:Why should filter core be used in backwash of ceramic filter?
- The filter in the water filter of ceramic filter is used for filtering water.
- Q:Common troubles of ceramic filter
- Ultrasonic cleaning, ceramic filter plate cleaning is not clean. The main reason is that the power box is faulty, the power supply is burned out, the line is aging, the energy head is burned out, the ultrasonic box is broken down, and the water level in the pulp tank is too low;
- Q:Ceramic filter capacity.
- 60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
- Q:Influence factors of ceramic filter
- On the other hand, as the spindle speed slows down, the thickness of the slurry is thickened, and the moisture of the concentrate is also affected. For viscous material, ceramic filter with ceramic plate to work as filter media, when the cake is formed gradually into the porous filter medium filter cake itself, and the cake is not easy to form a viscous material, forming a dry cake appearance does not slow, the spindle speed is easy to reduce the water content of concentrate. Similarly, the spindle speed is accelerated, the cake formation time in the vacuum zone is shortened, and the slurry thickness is reduced, and the material can be improved for the easy molding material. But the spindle speed is too fast to be cleaned after each cycle of the ceramic plate. As for the viscous material, the cake is difficult to form after the spindle speed increases, and it will affect the capacity. Therefore, the use of ceramic filter should focus on the inherent nature of the concentrate to explore the best spindle speed. Generally, the higher the temperature, the smaller the viscosity of the liquid, the more conducive to improve the filtration rate, reduce the cake or sediment water, while reducing the viscosity of the slurry, can improve the processing capacity.
- Q:What are the poor filtration effects of vacuum disc filters?
- Under normal circumstances, high vacuum, vacuum suction, high production capacity, filter cake moisture control is good. At present, some ceramic filters are equipped with two or multi-stage vacuum system to obtain almost absolute vacuum, and can reach 0.09 ~ 0.098MPa.
- Q:What is the filtration accuracy of 50nm ceramic membrane?
- It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
- Q:What is the backwashing pressure of the ceramic filter?
- Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.
- Q:The working principle of ceramic filter
- The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.
