 2.Component of Best price Volute sludge dewatering filter press for domestic sewage treatment:

The structure of the filter press consists of three parts:

Folding rack

The frame is the basic part of the filter press, both ends of the thrust plate and pressure head, both sides of the beam will be attached to the two together, the beam to support the filter plate, filter box and compression plate. In order to meet the high health needs, the rack needs to be wrapped with stainless steel. Package stainless steel technology can do reference, its quality can meet the needs of European customers.

A, thrust plate: it is connected with the seat filter press one end is located on the foundation, the chamber filter press the middle of the thrust plate is the feed

Hole, four corners and four holes, the upper corner of the hole is the washing liquid or press gas inlet, the next two corners for the export (undercurrent structure or filtrate outlet)

B, compression plate: used to press the filter plate filter, both sides of the roller to support the compression plate in the beam on the track rolling.

C, beam: is the load-bearing components, according to the use of environmental protection requirements, you can choose rigid PVC, polypropylene, stainless steel or new anti-corrosion coating coating.

Folding and pressing mechanism

Manual compression, mechanical compression, hydraulic compression.

A, manual compression: is a screw-type mechanical jack to push the compression plate will be pressed plate.

B, mechanical compression: compression mechanism by the motor (equipped with advanced overload protector) reducer, gear pay, screw and fixed

Nut composition. When pressed, the motor is turning, driving the reducer, gear to pay, so that the screw in the fixed silk mother in the rotation, pushing the compression plate will filter plate, filter box compression. When the compression force is getting bigger and bigger, the motor load current increases, when the protector set to the current value, to achieve the maximum clamping force, the motor cut off the power, stop the rotation, because the screw and fixed wire mother is reliable Of the self-locking helix angle, can reliably ensure that the work of the compression state, when returned, the motor reversal, when the compression plate on the briquetting, touch to the trip switch back to stop.

C, hydraulic compression: hydraulic compression mechanism composed of hydraulic station, cylinder, piston, piston rod and piston rod and pressure plate with

The structure of the hydraulic station is: motor, oil pump, relief valve (regulating pressure) valve, pressure gauge, oil, fuel tank. When the pressure is greater than the frictional resistance of the pressing plate, the pressing plate slowly presses the filter plate, and when the pressure is greater than the frictional resistance of the pressing plate, when the pressure is greater than the frictional resistance of the pressing plate, When the pressure is set to the pressure set by the relief valve (indicated by the pressure gauge pointer), the filter plate, the frame (plate and frame) or the filter plate are pressed and the relief valve starts unloading. , Cut off the motor power, pressing the action is completed, when the return valve, the pressure oil into the cylinder of the rod cavity, when the oil pressure to overcome the friction plate compression, the compression plate began to return. Hydraulic compression for the automatic packing, the compression force is controlled by the electrical contact pressure gauge, the pressure gauge upper limit pointer and lower limit pointer set in the process of the required value, when the pressure reaches the upper limit of the pressure gauge, the power Shut down, the pump to stop the power supply, due to the oil system may produce leakage and leakage caused by the pressure drop, when the lower limit to the pressure gauge pointer, the power is connected, the oil pump began to pressure, the pressure reaches the upper limit, The oil pump stops the oil supply, which circulates to achieve the effect of ensuring the compression force during the filtration of the material.

Folding filter mechanism

The filter mechanism is composed of a filter plate, a filter box, a filter cloth and a pressing diaphragm. The filter plate is covered with a filter cloth on both sides. When the press diaphragm is to be arranged, a group of filter plates is composed of a diaphragm plate and a side plate. Diaphragm plate on both sides of the substrate covered with rubber diaphragm, diaphragm coated with a filter cloth, the side plate that is ordinary filter plate. Material from the thrust plate on the material into the filter chamber, the solid particles because of its particle size is larger than the filter medium (filter cloth) aperture was trapped in the filter room, the filtrate from the bottom of the filter plate out of the liquid outflow. Filter cake needs to be squeezed, in addition to the use of diaphragm pressure, but also with compressed air or steam, from the washing mouth access, air flow to filter the water in the filter cake to reduce the moisture content of the filter cake.

(1) filter mode

The filtrate flows out in a clear flow filter and undercurrent filtration.

A, bright flow filter: the bottom of each filter plate out of the hole with water Tsui, the filtrate intuitively from the water Tsui out.

B, undercurrent filter: the bottom of each filter with a liquid channel hole, a number of filter plate out of the liquid hole into a liquid

Road, from the thrust plate below the outlet hole connected to the pipeline discharge.

(2) washing method

When the filter cake needs to be washed, there is a one-way wash and two-way washing, dark flow one-way washing and two-way washing.

A, bright flow one-way washing is, wash liquid from the thrust plate of the lotion into the hole in turn, through the filter cloth and then through the filter cake, from the non-porous filter plate outflow, then the hole out of the water nozzle is closed State, the outlet of the non-perforated nozzle is open.

B, bright flow two-way washing is, the lotion from the top of the push plate on both sides of the lotion into the hole has twice washed, that is, wash the first side of the washing and then from the other side of the washing, Angle direction, so called two-way cross-washing.

C, dark flow unidirectional flow is, the lotion from the thrust plate of the lotion into the hole in turn into the perforated plate, through the filter cloth and then through the filter cake, from the non-porous filter plate out.

D, undercurrent two-way washing is the lotion from the top of the board on both sides of the two wash into the hole has two washing, that is, washing from the side of the washing, and then from the other side of the washing, the export of dipping Direction, so also called the undercurrent bidirectional cross-washing.

(3) filter cloth: filter cloth is a major filter media, filter cloth selection and use of the filter effect has a decisive role in the selection of the material according to the PH value of the filter, solid particle size and other factors use the appropriate filter cloth Material and aperture to ensure low filtration costs and high filtration efficiency, use, to ensure that the filter cloth leveling is not discounted, aperture flow.
