Abstract
The utility model relates to a filtering and back washing device which comprises a water storage tank, wherein a casing is mounted inside the water storage tank, a filtering pore plate is arranged inside the cavity of the casing, the cavity of the casing is divided into a first cavity and a second cavity, a water inlet is mounted above the casing, the water inlet is connected with a one-way check valve mounted inside the first cavity, and a one-way check valve is mounted inside the second cavity and connected with a water outlet mounted on the casing through a buckle. The filtering and back washing device has a compact structure, is reasonable in design, can prevent that sewage water directly enters into the water storage tank of the equipment and enables a water pump impeller to rotate in a reversing manner and causes the failure of bolt looseness and dropping off the fastened impeller. The invention solves the problem that the flowing passage of sewage enables sewage directly enter into the water storage tank of the equipment after entering the filtering and back washing device and through filtering and do not enter into the water pump impeller, and overcomes the defect of bolt dropping of the fastened impeller caused by reversal of the water pump impeller during water entering of conventional sewage discharge equipment.
Description
Technical field
The utility model relates to a kind of filtration back purge system, especially relates to a kind of filtration back purge system that sewage promotes exhaust apparatus that is used for.
Background technology
At present, filter backpulsing hypogee sewage discharge equipment, can not cause water pump vane contact, water pump is had protect and the function in prolongation water pump service life with foreign material in the sewage because of it filters backwashing technology; Need not the foreign material in the equipment are drawn clearly, characteristics such as environment for use are not polluted in operation under sealing state; By the increasing sewage discharge engineering that is used for the underground structure.In the process of sewage access arrangement water tank, need the flow through outlet of water pump of sewage after filtering is in the storage tank of the suction inlet access arrangement of flow through again water pump vane and water pump.When the discharge of sewage was big, current can drive the impeller counter-rotating of water pump.Be prone to cause the fastening bolt of water pump vane to pitch the shortcoming of water pump cisco unity malfunction.
Summary of the invention
The purpose of the utility model is to overcome the weak point that exists in the above-mentioned technology; A kind of compact conformation, reasonable in design is provided, adopts this device to make sewage after getting into the filtration back purge system, after filtering; The storage tank of direct access arrangement; Without the impeller of water pump, overcome water pump vane counter-rotating when having the water inlet of sewage discharge equipment now, cause the filtration back purge system of the bolt falling of fastening impeller.
In order to achieve the above object, the technical scheme of the utility model employing is: comprise storage tank, housing is installed in storage tank; Be provided with orifice filter in the shell cavity; Shell cavity is divided into two chambers, and first chamber, second chamber are equipped with water inlet above housing; Water inlet is connected through the one way stop peturn valve of installing in buckle and first chamber, one way stop peturn valve is installed in second chamber is connected through the delivery port of installing on buckle and the housing.
The utility model has the advantages that:
1, compact conformation, reasonable in design has been avoided making the water pump vane backward rotation in the storage tank of sewage through the water pump access arrangement, the fault that causes the bolt looseness of fastening impeller to come off;
2, the utility model patent has solved the passage of flowing through of sewage; Make sewage after getting into the filtration back purge system; After filtering, the storage tank of direct access arrangement is without the impeller of water pump; Overcome water pump vane counter-rotating when having the water inlet of sewage discharge equipment now, cause the shortcoming of the bolt falling of fastening impeller;
3, adopt the special-shaped orifice filter with direction diversion Design theory, current pass through orifice filter fast under the filtration state, and foreign material are difficult for stopping up eyelet, and under the backwash state, pressure flow forms jet under the guiding of guiding gutter, and foreign material are prone to come off.

The specific embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Can know that by Fig. 1-Fig. 4 the utility model comprises storage tank 11, housing 3 is installed in storage tank 11; Be provided with orifice filter 4 in housing 3 cavitys; Housing 3 cavitys are divided into two chambers, and first chamber 12, second chamber 13 are equipped with water inlet 2 above housing 3; Water inlet 2 is connected through the one way stop peturn valve of installing in buckle and first chamber 12 9, the delivery port 5 of one way stop peturn valve 8 through installation on buckle and the housing 3 is installed in second chamber 13 is connected.
Described housing 3 one ends are provided with access hole 1, and access hole 1 is installed in storage tank 11 outsides.
In second chamber 13, be positioned at pressure water inlet 6 positions one way stop peturn valve 7 is installed.
Lower end part is provided with pressure outlet pipe 10 in first chamber 12.
Be evenly equipped with pod apertures 15 on the described orifice filter 4.
The utility model is in the water inlet 2 of the sewage that contains foreign material through device, unidirectional check device 9 access to plant chambeies, and sewage filters interception through flow guiding type orifice filter 4 access to plant chambeies in the chamber of device with foreign material; Sewage is in in-line arrangement delivery port 5 access arrangement storage tanks 11.When the outer rows water pump 14 of device is worked; Pressure flow is in pressure water inlet 6 accesss to plant of device; One way stop peturn valve 7 is opened, and pressure flow is closed the unidirectional check device 8 in the device lumen, and pressure flow is in first chamber 12 of flow guiding type orifice filter 4 accesss to plant; Unidirectional check device 9 is closed; Pressure flow through pressure outlet pipe 10 dischargers, realizes the foreign material in the chamber of device foreign material are filtered in the sewage not contact water pump 14 impellers, and the purpose of together discharging with the pressure flow that water pump 14 produces.
Below sketch its course of work: the sewage that contains foreign material passes through in the water inlet 2 of device, the unidirectional check device 9 access to plant chambeies, and sewage filters interception through filtering holes plate 4 accesss to plant second chamber 13 in first chamber 12 of device with foreign material; Sewage is through in-line arrangement delivery port 5 bleeders.When the outer rows water pump 14 of device is worked; Pressure flow is in pressure water inlet 6 accesss to plant of the water pump 14 of device; One way stop peturn valve 7 is opened, and the unidirectional check device 8 that pressure flow will install in second chamber 13 is closed, and pressure flow is in first chamber 12 of flow guiding type orifice filter 4 accesss to plant; Pressure flow is closed unidirectional check device 9; Through pressure outlet pipe 10 dischargers, foreign material are filtered and do not contact water pump 14 impellers pressure flow in the realization sewage with the foreign material in the chamber of device, and together discharge with the pressure flow that water pump 14 produces.
