Blade filter

Blade filter intro

GLJ series automatic slagging filter is developed by our company according to the common problems of solid-liquid separation and filtration in various industries, and the introduction of international technology in the industry. The filter leaf adopts special stainless steel filter screen, which has long life, large output and high precision. Self-created oil pressing mechanism, low oil content in the slag, easy to operate, easy to discharge, suitable for oil, chemical, pharmaceutical and other industries in the production of decolorized oil filtration, clarification filtration, crystal filtration separation process, especially to solve the oil industry in cottonseed, rapeseed, castor and other machine-pressed crude oil is difficult to filter, not easy to discharge the slag and other problems.

Comparison of the use effect of automatic slag filter

Blade filter Working principle

Automatic slagging filter by the gear oil pump (centrifugal pump) the mixing tank mixed clay mixture liquid pumped through the pipeline into the filter tank and filled with, under the thrust of the pump, through the circulation of large particles of clay on the surface of the filter screen to form a filter cake layer, under the action of the filter cake layer, fine particles of clay are trapped to form countless fine channels. Then the more subtle suspended matter is intercepted, only clear liquid is allowed to pass, then filtration begins, in the filtration process through the continuous new clay mixture pumped into the formation of a new filter cake layer, so that the filter cake will not be blocked, so that the material through the filter cake layer for substantial filtration, clear liquid through the filter screen internal channel through the oil nozzle flow to the outlet pipe, Under the thrust of the pump, it flows through the pipeline to the finished product tank.

Filter slagging process

With the increase of the filtration amount of the clay mixture, the cake layer becomes thicker and thicker, the filtration resistance increases, and the pressure in the tank rises. When the pressure gauge at the part of the filter machine shows 0.4Mpa, stop conveying the clay mixture into the filter tank, start the air compressor, and input air into the filter tank through the overflow port through the pipeline. Under the action of air pressure, the oil in the cake is gradually pressed out. After about 30 minutes, the filter cake is pressed dry, stop the input of air into the filter, when the pressure gauge of the filter part shows 0, open the butterfly valve, start the vibration body, and start the slag discharge, when the slag discharge is clean, close the butterfly valve and all valves, and start the next round of filtration.

Blade filter Technical parameter

Blade filter peculiarity

● Mechanical vibration automatic slagging, open the butterfly valve, start the vibration slagging device, vibration slagging, reduce the labor intensity of workers, to achieve continuous operation.

● Special filter plate, no filter cloth, filter paper, automatic slag filter adopts special stainless steel composite braid filter, corrosion resistance, easy cleaning, long life, can be used for 3-5 years, low maintenance cost.

● Closed environmental protection, in line with environmental standards, pipeline connection, fully closed filtration, products do not volatilization, do not throw, good quality.

● High energy saving efficiency, filter liquid slag or activated carbon (white soil), or decolorization filter, can replace the plate and frame filter.
