Abstract
A back-wash flow-guiding non-return dirt separator adopts a tangent arc parabola flow guiding plate as a main body structure; waterflow almost has no resistance loss, and an upper tangent arc parabola reinforcing rib and a lower tangent arc parabola reinforcing rib are arranged on the main body structure, so that the reinforcing effect and the flow guiding effect are taken. The symmetric dual tangent arc parabola structure enables waterflow to be dispersed or collected fully, so that a filter part of a filter screen is fully cleaned, a self-cleaning effect is taken, the service life of the filter screen is greatly prolonged, the maintenance period of a filtering device is prolonged, the cleaning time is shortened, the water for cleaning is reduced, and the energy-saving and environment-friendly effects are taken; in addition, a valve flap is arranged at a water inlet, and when the valve flap is cleaned, dirt is discharged from an independent drain outlet, so that the secondary pollution of a stock solution is avoided, the dirt in the system is effectively removed, and an effect of protecting a pipe network is taken. Compared with the similar cleaning filtering device, the back-wash flow-guiding non-return dirt separator is applicable to occasions such as cleaning and flow guiding, automatic cleaning, water draining and mechanical impurities removal.
Description
Technical field
It is a kind of backwash diversion check dirt separator.Simple in structure, long service life, on HVAC and plumbing industry, prevent clean not thoroughly and prevent from polluting for the second time stoste, good seal.
Background technology
Dirt separator, be arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for removing the impurity in medium, with the normal use of protection valve and equipment.Simultaneously, because common dirt separator easily causes foreign material to block screen pack and pollutant holding capability is little, cumbersome, and make large-scale filter plant comprehensively be cleaned and avoid the pollution for the second time of stoste, make like this we in the urgent need to a kind ofly having comprehensively, thoroughly, the filtration guiding device of automatically cleaning, environmental protection.
Summary of the invention
The utility model content is: in conjunction with the principle of dirt separator and improved, invent out a kind of with deflector and check device, and realize utilizing the backwash diversion check dirt separator of the cleaning and filtering net after filtration.
The utility model solves the technical scheme that its technical problem adopts: the backwash diversion check dirt separator that adopts case lid, non-return flap, screen pack, deflector and casing to form, described non-return flap, screen pack, deflector are in casing, be placed with water inlet, delivery port and sewage draining exit on described casing, delivery port on casing and sewage draining exit adopt reducer pipe, make the current enlarged areas, make blowdown more smooth; All be welded with groove on bottom half and case lid, for fixing screen pack, screen pack is vertically placed, and casing is divided into to the space of two formed objects, and screen pack filters stoste, and the solid impurity in stoste is deposited near the bottom half sewage draining exit; Described deflector is sheet metal lining tetrafluoro rubber, prevents corrosion and wear-resisting; Described deflector is placed on the port of export and is welded on relevant position screen pack and outlet evenly are divided into to three zones, deflector adopts the tangent line circular arc line main body mechanism of dishing out, current are through almost non-resistance loss, also add upper and lower two tangent line circular arcs line reinforcement of dishing out on agent structure, be conducive to the comprehensive cleaning and filtering net of current; Described non-return flap is welded on the box house water inlet and stops the water in casing to be got back in stoste, and the non-return flap is light can be opened flexibly, and the fixed axis be centered around on casing freely rotates.When the cleaning and filtering net, the non-return flap is closed due to the active force that loses stoste with under the effect of gravity, has guaranteed the isolated of cleaning fluid and stoste, has avoided the pollution for the second time of stoste; The non-return flap is sheet metal lining tetrafluoro rubber, wear-resisting, corrosion resistant, and sealing effectiveness is good.
The beneficial effects of the utility model are: resistance is little, and screen pack is cleaned in time, and it is more smooth and easy that medium circulates; Screen pack is difficult for stopping up, and the anti-deflector that cleans can be followed comprehensive cleaning and filtering net; Filter efficiency is high, and each mesh on screen pack can play a role in filtering, and during blowdown, closure of check ring, guaranteed the isolated of cleaning fluid and stoste; Pollutant holding capability is large, can hold more impurity.
The accompanying drawing explanation
Fig. 1 is this backwash diversion check dirt separator sewage disposal schematic diagram.
Fig. 2 is the water backwashing screen pack after this backwash diversion check dirt separator utilization filtration the schematic diagram that the foreign material in casing are discharged.
In figure: 1, case lid, 2, the non-return flap, 3, screen pack, 4, deflector, 5, casing, 5-1, water inlet, 5-2, delivery port, 5-3, sewage draining exit.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
In Fig. 1, it is this backwash diversion check dirt separator sewage disposal schematic diagram, under non-return flap (2) normally open, medium is filtered: the non-return flap (2) of water inlet (5-1) is opened under the effect of medium, medium enters casing (5), screen pack (3) is filtered medium, and impurity is blocked and is deposited near casing (5) bottom blow-down mouth (5-3), and the impurity after filtration flows out from device delivery port (5-2).
In Fig. 2, screen pack (3) is cleaned and removing is deposited on the impurity dirt of casing (5) bottom: the non-return flap of water inlet (5-1) is due to the self gravitation closure, cleaning fluid enters from device delivery port (5-2), through deflector (4), deflector (4) is cleaned screen pack (3) fully, and the impurity that cleaning fluid process screen pack (3) will be deposited at the bottom of case is removed and discharged from the sewage draining exit (5-3) of bottom.
Claims (4)
