Abstract
The invention relates to a laminated filter unit, which belongs to a component of a laminated filter. The filter unit comprises a shell, wherein the shell is provided with an inlet and an outlet; a piston, a piston sleeve and a piston seat are arranged in the shell; the side wall of the piston sleeve is arranged on a lamination assembly; the lower part of the lamination assembly is provided with centrifugal flow guide blades; and a check valve is arranged between the centrifugal flow guide blades and the outlet. Impurities in liquid get away from the lamination assembly and move upwards by centrifugal force produced by the liquid rotating at a high speed and are finally centralized at the top end of the laminated filter unit, so that the back wash frequency of a product is greatly reduced. In a back wash state, after a high-pressure clean water flow is gathered to a flow guide pipe in a reverse direction, the water flow enters a piston chamber through a piston hole at the top end of the flow guide pipe, and the piston sleeve overcomes outward movement of the spring pressure on the top so as to release the pressure applied to the lamination assembly; and by now, the lamination assembly is loose, and the cleaning water flow can extremely easily pass through each lamination to clean impurities inside and outside a laminated filter tank.
Description
Technical field
The present invention relates to the lamination filter element, belong to the parts of lamination filter.The lamination filter is widely used in the water filtration of industrial circles such as food, weaving, metallurgy, plastics, medicine, papermaking and building.Filtration grade is confirmed requirements in water quality requirements in water quality, water occasion by back level water system or equipment.
Background technology
The traditional filtering unit when forming filter set in order to guarantee that filter set can normal, safe and effective work; All to increase the centrifugal sandstone separator of a cover at the equipment leading portion; To alleviate the work load of filter set, adopt the drawback of this configuration to be: input cost is high, the occupied ground area is big, the installation and maintenance difficulty is big.The structure of tradition lamination filter lamination group under any circumstance all is close-connected; Under the backwash state, stack of laminations does not have automatic loose process, and anti-washing water flow can only under high pressure be washed through the slit between the video disc; Cleaning performance is relatively poor; And the impurity that is hidden in the filter pocket between the lamination can not get effective cleaning basically, when having only stack of laminations under the backwash state, to be loose condition (of surface), could thoroughly be cleaned up attached to the impurity in the video disc filter pocket.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Like Fig. 1-shown in Figure 6:
Filter:
The liquid that contains impurity is got into lamination filter element inside and is got into centrifugal flow guiding blade 12 by import;, liquid produces rotation at a high speed when passing through centrifugal flow guiding blade 12; At a high speed the centrifugal force that produces of the liquid of rotation makes impurity in the liquid away from stack of laminations 5 and move up; Finally concentrate on lamination filter element top, greatly reduce the backwash frequency of product.Liquid filters entering stack of laminations inside through stack of laminations 5 slits under the effect of system pressure, the impurity in the liquid is blocked in the periphery of stack of laminations 5, thereby has reached the purpose of filtering.Clean liquid after being filtered overcomes the non-return valve spring pressure under the effect of system pressure, back down non-return valve, and non-return valve is opened, and liquid flows out through outlet thus.In said process, because the active force of the piston spring 7 at liquid pressure and stack of laminations 5 tops from outside to inside compresses stack of laminations 5 piston bush 3 all the time, thereby guaranteed the filtering accuracy and the quality of filter element.
Backwash:
One, during the backwash state, the imported valve of filter element is closed, and it is inner that the clean liquid that is provided by other filter elements gets into the lamination filter element from outlet.
Two, after backwash liquid gets into lamination filter element inside; Because the unidirectional characteristic of non-return valve; Liquid can not directly get into stack of laminations inside through central inlet, and compelled by pod apertures and mozzle 10 entering, and through being evenly distributed on the nozzle ejection on the mozzle.
Three, the direction of the nozzle of mozzle 10 becomes certain included angle to arrange with stack of laminations 5 circumference, in stack of laminations, has formed an annular water flow of rotation at a high speed, and at this moment each position of stack of laminations has all obtained cleaning effectively.
Four, simultaneously; Arrive in a flash in backwash; Stack of laminations 5 top piston cover 3 is pushed open by the liquid in the mozzle 10, and the lamination that is pressed becomes loose shape, rinses well together from the impurity that rotating liquid will be attached in the lamination filter pocket and video disc is outside of nozzle.
Five, the liquid that carries impurity is discharged through import.
Under the backwash state; After the clean current of high pressure gathered mozzle 10 in the other direction, pressure sharply raise and reaches system works pressure, and at this moment current get into piston chamber 2 through the piston hole 8 on mozzle top; Form an expansionary force from inside to outside; Outwards move because the apply piston of this power cover 3 overcomes the top spring pressure, thereby discharged the pressure that is applied on the stack of laminations 5, at this moment 5 one-tenth loose shapes of stack of laminations; Washing water flow cleans up reaching foreign matter in the lamination filter pocket easily through each lamination.
What should explain at last is: the above is merely explanation embodiment of the present invention; Be not limited to the present invention; For a person skilled in the art; All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
