Plate-type closed filter makes people shine

The pressure difference of the plate type closed filter is set to discharge the sewage. When the filter body is filtered and discharged, it will produce a certain pressure difference. The greening and environmental protection products that are getting more and more attention are now frequently listed, self-cleaning filters. It is a new type of equipment that Zui is eye-catching. In recent years, the increasingly serious environmental degradation and water shortages have led to the continuous introduction of water-saving and environmentally friendly products in the market. As soon as the plate-type closed filter was introduced, everyone would be surprised and amazed.

The plate type closed filter is a new century high-tech product developed for water filtration. The working principle is simple and unique. The water reuse technology refers to the water and sewage of residential residents including: bathing, washing, washing, kitchen, toilet and other water sources. After centralized treatment, a certain standard is reached for greening and watering of the community, and the vehicle is flushed. When the pressure difference reaches the value set by the user, the drain valve switch is opened by itself to discharge the sewage. After the dirt is removed, the pressure difference is reduced and automatically closed for the next cycle of operation.

The plate-type closed filter guarantees a reasonable level of feed concentration. In theory, the higher the concentration of the filter press, the better, the higher the concentration, the shorter the filter press cycle, the larger the treatment capacity, the better filter cake moisture and the lower solids content in the filtrate. However, China's coal preparation plant generally enters the plate-type closed filter with the bottom stream of the simmering concentrator. The excessive underflow concentration brings hidden dangers to the normal and safe operation of the simmering concentrator. If the excessive underflow concentration is pursued, it may cause squatting. The concentrator is crushed and affects normal production. Therefore, the feed concentration of the plate type closed filter should be kept at 400-600g/l, so that the required feed concentration of the filter press can be ensured, and the normal operation of the 耙-type concentrator can be ensured. The plate type closed filter ensures a reasonable feed size. Most of the coal slurry treatment systems in China's coal preparation plants use filter presses to recover the slime to achieve closed water washing. However, some coal preparation plants use coal slime centrifuges (high-frequency sieves) or other equipment to cooperate with coal slime filter presses. Achieve slime recovery and closed water wash.

Plate type closed filter picture

The plate type closed filter must be kept clean, can not contain mud sand, use water to circulate, the water temperature should not be too high during the cycle, but it should not be too low, because too low will affect the degree of vacuum, but can not break the water. The filtrate can not be pumped into the vacuum pump, which will cause some wear on the impeller and the body, so that the vacuum pump can not function and affect the moisture of the filter cake, causing damage to the equipment. Therefore, the filtrate should be properly pumped into the plate type closed filter, and the high-altitude separator can be used. . After we have finished using the equipment, we first rinse the cooking oil left on the equipment. The main thing is to clean the dead corners of the equipment. When we hear that the noise of the equipment is getting louder, it means that the gears of the equipment may be worn out or because of the lack of oil in the gears of the equipment. At this time, we need to replace the gear of the equipment or add oil.

Different types of plate-type closed filter machines have certain problems, and everyone should do the corresponding work when doing this part of the work. At this point, everyone needs to know enough about the plate type closed filter before checking the plate type closed filter. Do not know where the equipment may be in trouble, and start to check. Such inspection will undoubtedly waste a lot of time.

Of course, in the process of overhaul, you should also record the problem in time. For example, where are the problems, what are the reasons for these problems, and then plan for the later maintenance work, and put forward Some suggestions and requirements for maintenance personnel to refer to, Zui finally ensure that the use of plate-type closed filter is in line with actual needs.
