Plate and frame pressurized oil filter machine customized in Shanghai

Plate and frame pressurized oil filter machine customized in ShanghaiIt mainly consists of a fixed plate, filter frame, filter plate, compression plate, and compression device, and has a similar appearance to a box filter press. The materials used to manufacture boards and frames include metal, wood, engineering plastics, and rubber, and there are various forms of filter plate surface grooves as drainage channels. The filter frame is hollow.

Product Features:

1. It can be applied to suspensions with high compressibility or near incompressibility of filter residue. The solid particle concentration of suitable suspensions is generally below 10%, and the operating pressure is generally 0.3~1.6 megapascals, with some reaching 3 megapascals or higher. The filtering area can increase or decrease with the number of frames used. The frame is usually square in shape, with an inner edge length of 200-2000 millimeters, a frame thickness of 16-80 millimeters, and a filtering area of 1-1200 square meters. The board and frame are tightened using manual screws, electric screws, and hydraulic methods. The board and frame are made of materials such as wood, cast iron, cast steel, stainless steel, polypropylene, and rubber.

2Plate and frame pressurized oil filter machine customized in ShanghaiDue to its large weight and volume, this type of sludge dewatering machine adopts an intermittent operation mode, producing 50kg/h of solids per hour. The productivity is relatively low, but the dewatering rate is high, and the moisture content of the sludge cake can reach 70% -85%. In addition, this equipment also requires dedicated personnel to guard it, and its automation is poor; Multiple moving parts and instability; Equipment investment is slightly lower; Difficulty in maintenance; The operation is relatively complex and requires dedicated management; Characteristics such as short service life.

Operating procedures:

(a) The operator must be familiar with the performance and debugging methods of the machine.

(b) Clean the pipeline system and machine interior.

(c) After starting the machine, the reading of the pressure gauge and the operation of the machine should be checked regularly. Once an abnormality occurs, the machine should be stopped immediately, and the fault should be eliminated before restarting.

(d) According to the oil filtration capacity, after circulating and filtering 2-3 times the amount of oil, open the oil-water nozzle and take out the oil sample for testing until it is qualified.

(e) After working for a certain period of time, if the pressure rises above 0.5 MPa or decreases compared to the initial pressure, the system filter paper will break or the filter paper will absorb a large amount of water and expand the capillary pores, both of which have lost their filtering ability.

(f) The safety valve has been inspected and adjusted before leaving the factory, and sealed with lead seals. It cannot be disassembled at will. If it is necessary to make adjustments, it must pass the test before continuing to use.

(g) When working, pay attention to the oil gauge. If there is too much oil in the oil pan, open the return valve to drain the oil from the pan, and then close the return valve.

(h) When there is too much water in the oil, the oil should be heated to evaporate some of the water, and then filtered after cooling to room temperature.

(i) After filtering, the machine should be cleaned, coated with rust proof oil, and placed in a dry and ventilated place.

Notes:

Keep the machine clean regularly.
The ears of the filter plate and frame are relatively fragile, so they should be handled gently when using,
When pushing the oil filter, the speed should not be too fast to avoid damaging the equipment due to strong impact on the machine.
Lubricating oil should be added regularly on the tightening screw nut.
When using an oil filter, the motor casing should be electrically grounded to prevent accidents and static electricity caused by poor insulation of the motor.
When opening the upper and rear boxes, do not apply too much force to avoid damaging the parts.
The connecting bolts between the motor and the frame should be checked regularly to prevent loosening.
If insufficient oil filtration is found, the following 5 aspects can be checked:

(1) Are there any air leaks in the suction pipe, return pipe, and joints.
(2) The suction pipeline is too long (generally not exceeding 5 meters) or the diameter does not meet the regulations.
(3) Is the oil inlet pipe blocked.
(4) Is there any other accessory installed in the suction pipe that causes excessive resistance.
(5) Whether the gear pump and safety valve are loose or not.
