It is also connected on the vacuum tank and is provided with high-pressure water pipe, the high-pressure water pipe is connected with stabilized pressure pump.

Preferably, above-mentioned high-pressure washing disc-type pretreatment filtering device, wherein the inlet valve, which is also connected with, to be set It is equipped with backwash pipeline.

Above-mentioned technical proposal has the characteristics that：

The utility model high-pressure washing disc-type pretreatment filtering device is simple and compact for structure, and floor space is small, operation at This is low, and filtering traffic is big, and backwash efficiency is high, and backwash synchronous can be carried out with filtering, improve working efficiency.

Description of the drawings

With reference to appended attached drawing, more fully to describe the embodiments of the present invention.However, appended attached drawing is only used for Bright and elaboration, does not constitute the limitation to the scope of the utility model.

Fig. 1 is the vertical view of high-pressure washing disc-type pretreatment filtering device.

Fig. 3 is the front view of high-pressure washing disc-type pretreatment filtering device.

Specific implementation mode

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as the utility model It limits.

As shown in Figure 1, Figure 2 and Figure 3, the utility model high-pressure washing disc-type pretreatment filtering device has specifically included：

Water inlet line 1 and outlet conduit 2 are provided with disc-type filter 3, disc-type between inlet and outlet pipes It is provided with inlet valve 4 between filter 3 and water inlet line, flowing water Valve is provided between disc-type filter and outlet conduit 5, pressure gauge 9 is provided on water inlet line 1, vacuum tank 7 is provided on outlet conduit, vacuum tank 7 and flowing water Valve 5 are total It is same to be connected on a pressure reservoir pipe 8.

Further, it is also connected on vacuum tank 7 and is provided with high-pressure water pipe 10, high-pressure water pipe 10 is connected with voltage stabilizing Pump 11.

In the embodiments of the present invention, it is preferred that inlet valve 4, which is also connected with, is provided with backwash pipeline 6.

For the utility model high-pressure washing disc-type pretreatment filtering device in specific works, electronics waste water is by water inlet pipe Road, inlet valve, which enter in disc-type filter, is filtered processing, after there is filtering lamination to compress in disc-type filter Particular filter channel is formed, the particulate matter that grain size is smaller in electronics industry waste water can be intercepted；It is filtered through disc-type filter laggard Enter to outlet conduit, be discharged by outlet conduit, after certain run time, can be controlled with the controller of each valve connection corresponding Valve changes circulating direction, realizes the backwash of disc-type filter by the hydraulic pressure of vacuum tank according to setting time, will retain Pollutant recoil and be discharged by backwash pipeline, and unified collection processing can effectively ensure filtering traffic, will not go out Existing clogging；Wherein backwash may be implemented in technical solutions of the utility model and filter synchronous carries out, specifically, controller system When system reaches according to the work period of a dishful of type strainer or pressure at two ends difference reaches setting value, closes and is filtered with the disc-type The inlet valve of device connection, opening simultaneously flowing water Valve corresponding with the inlet valve, (other valves still maintain normal shape State), then the hydraulic pressure of vacuum tank enters in pressure reservoir pipe, and the hydraulic pressure in pressure storage tube is by open flowing water Valve to this Disc-type filter is backwashed, other disc-type filters still maintain filtration state；Preferably, voltage stabilizing pump startup It can supplement voltage stabilizing pressure tank, ensure backwash best results, be easier that removal pollutant grain size is small, concentration is high, easily adheres to Pollutant.

In conclusion the utility model high-pressure washing disc-type pretreatment filtering device is simple and compact for structure, floor space Small, operating cost is low, and filtering traffic is big, and backwash efficiency is high, and backwash synchronous can be carried out with filtering, improve working efficiency.

The preferred embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as with the common side in this field Formula is practiced；Any technical person familiar with the field all may be used in the case where not departing from technical solutions of the utility model ambit Many possible changes and modifications are made to technical solutions of the utility model using the methods and technical content of the disclosure above, or are repaiied It is changed to the equivalent embodiment of equivalent variations, this has no effect on the substantive content of the utility model.Therefore, every without departing from this practicality The content of new technique scheme, any simple modification made to the above embodiment of foundation the technical essence of the utility model, etc. With variation and modification, still fall within technical solutions of the utility model protection in the range of.
