Abstract
The utility model relates to a low backwash pressure laminated filter, which is composed of a filter shell body integrated by a water inlet, an outlet and an air pipe, a groove lamination, a cylinder, a piston and a center water collection pipe. The utility model is characterized in that: the pressure type of the lamination adopts air pressure method. When the backwash of the lamination filter is available, empty the compressed air in the cylinder firstly and the lamination surface is free from pressure, therefore the backwash pressure of the filter will be effectively reduced and the energy consumption will also be lowered.
Description
Technical field
The utility model relates to a kind of filter plant, is used for separating the suspended particles of water inlet, reduces the content of suspended impurity in the water inlet.
Background technology
Use at present the lamination filter as pre-processing device, the suspended particles that are used for separating water inlet are comparatively general, and it has characteristics such as water quality treatment wide ranges; But the lamination in the existing lamination filter adopts the spring compression mode, thereby when filter backwash, need overcome spring tension, needs big intake pressure when causing filter backwash like this, effectively the backwash filter; And because the frequent backwash of filter after spring fatigue intensity acquires a certain degree, will make spring tension reduce, cause that tightness degree reduces between lamination, influence the filtering accuracy of filter.
Summary of the invention
In the utility model, lamination in the filter compresses mode and adopts the air pressure form, like this when filter backwash, can be about to Compressed Gas emptying in the cylinder earlier, make the laminate surface of filter not have pressure, the lamination of filter is just loosening easily, only needs less hydraulic pressure during the lamination backwash, just can reach the desirable backwash effect of lamination filter; And because the mode that compresses of filtering has adopted the air pressure form, the tightness degree between lamination depends on the air pressure intensity in the cylinder, and the frequent backwash of filter can not influence the filtering accuracy of filter.
Technical solution of the present utility model is: in the lamination filter of forming with filter housing, band groove lamination, cylinder, piston, the center collector pipe of bringing outlet pipe and tracheae into, the lamination in the filter is arranged to cylinder promotion piston compresses mode.
The utility model is arranged to cylinder with the lamination in the filter and is promoted piston and compress mode, and when filter backwash, Compressed Gas in the emptying cylinder in advance so just can effectively reduce the backwash pressure of filter, reduction backwash energy consumption; Simultaneously because lamination contact tightness degree by the cylinder internal gas pressure decision that promotes piston, so just can effectively guarantee the filtering accuracy of lamination filter.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment
Composition structure of the present utility model such as accompanying drawing, outer guipure press former water to enter lamination 2 from mouth of a river a (or c), after being filtered by lamination 2, enter center collector pipe 5, by delivery port b output filtered water; When the filter operate as normal, compressed air enters cylinder 3 by gas port d, promotes piston 4 densification laminations 2.After lamination is filtered to a certain degree, owing to held back a certain amount of suspension on the laminate surface, cause the lamination filter pressure drop to strengthen, influence the filter effect of lamination filter, at this moment the lamination filter is carried out backwash, to recover its strainability with regard to needing.When the lamination filter backwash, band presses backwash water to enter center collector pipe 5 from mouth of a river b, and by center collector pipe water outlet backwash lamination 2, backwash water is by mouth of a river a (or c) discharging.When the lamination filter backwash, the Compressed Gas in the cylinder 3 is by the gas port d emptying of going ahead of the rest, and there is not pressure in lamination 2 surfaces like this, and lamination is become flexible easily, so just can effectively reduce the backwash pressure of filter.
Below to one the cover 20m
3/ h lamination filter example describes.Concrete result of implementation is as follows:
By above table as seen, under the identical prerequisite of backwash effect, the utility model can significantly reduce the backwash pressure of lamination filter, reduces the backwash energy consumption.
Claims (1)
1, a kind of low backwash pressure lamination filter, by the filter housing (1) of bringing outlet pipe and tracheae into, band groove lamination (2), cylinder (3), piston (4), and center collector pipe (5) forms, it is characterized by the interior lamination of filter, to compress mode be the air pressure form.
