product description

滤袋侧漏机率小,有力地保证了过滤品质。 Brief description: The side leakage probability of the filter bag is small, which effectively guarantees the filtration quality. Bag filter can carry greater working pressure, low pressure loss, low running cost and obvious energy saving effect. The filtration accuracy of the filter bag has been continuously improved and has reached 0.5 μm. The bag filter has a large processing capacity, a small volume, and a large dirt holding capacity. Based on the working principle and structure of the bag filter system, it is convenient and quick to change the filter bag, and the filter is free of cleaning, saving labor and time. Filter bags can be reused after cleaning, saving costs. Bag filter has a wide range of applications, flexible use and various installation methods.

First, the structure and working principle of the filter

Bag filter is a multi-purpose filter equipment with novel structure, small size, easy and flexible operation, energy saving, high efficiency, closed work and strong applicability.

The bag filter is a pressure filter device, which mainly consists of the main components such as a filter cylinder, a filter cylinder cover, a quick-open mechanism, and a stainless steel filter bag reinforcement net. The filter bag itself is installed in the reinforced mesh basket. The liquid can penetrate the filter bag with the required fineness level to obtain qualified filtrate, and the foreign particles are intercepted by the filter bag. The machine is very easy to change the filter bag, and the filter has almost no material consumption.

The main advantages of bag filter:

The probability of side leakage of the filter bag is small, which effectively ensures the filtration quality.

◆ Bag filter can carry greater working pressure, low pressure loss, low running cost and obvious energy saving effect.

◆ The filtration accuracy of the filter bag has been continuously improved and has reached 0.5 μm.

◆ Bag filter has large processing capacity, small volume, and large capacity for pollution.

◆ Based on the working principle and structure of the bag filter system, it is convenient and quick to change the filter bag, and the filter is free of cleaning, saving labor and time.

◆ Filter bags can be reused after cleaning, saving costs.

◆ Bag filter has a wide range of applications, flexible use and various installation methods.

Specification of bag filter

Bag filter is divided into: single bag filter, multi-bag filter and sandwich filter. Multi-bag filter, suitable for large flow filtration. From 2 bags to 24 bags,

Complete specifications, the diameter of the inlet and outlet flanges is φ50-450MM, and the maximum flow of a single machine is 90-1000m 3 / h. Can provide quick opening design, filter bag replacement is very convenient. It is also suitable for occasions where it is desired to replace the filter bag after a long time.

Third, with jacket heating

The sandwich bag filter has a double-layer structure, and the sandwich can be passed with steam or thermal oil to maintain or increase the temperature of the fluid, prevent the fluid from solidifying, increase the filtration speed of the viscous liquid, or meet the temperature requirements of the next process.

Fourth, filtering operation and precautions

The operation of this machine is simple. When using, you only need to install the filter bag with the required level of fineness in the filter cartridge, check whether the O-ring seal is intact, and then tighten the ring bolt of the filter cartridge cover to start working.

After the pump is started, the pressure gauge on the filter rises slightly, and the initial pressure is about 0.05MPa. As the use time increases, the filter residue in the cylinder gradually increases. When the pressure reaches 0.4MPa, the cylinder cover should be stopped to check the residue in the filter bag. In some cases, replace the filter bag and continue to use it (the filter bag is generally reusable by cleaning).

The filter pressure is generally adjusted to be 0.1-0.3MPa, which can be adjusted through the return line or the return valve on the pump. Excessive filter pressure will damage the filter bag and the protective net, which requires special attention.

Five, the main purpose

Paint, beer, vegetable oil, medicine, chemicals, petroleum products, textile chemicals, photosensitive chemicals, electroplating solution, milk, mineral water, thermal solvents, latex, industrial water, sugar water, resin, ink, industrial wastewater, fruit juice, food Oil, wax, etc.
