Description
Technical field
The invention belongs to mechanical engineering field, and in particular to a kind of Metal film type pressure differential filter.
Background technology
Metal film type pressure differential filter is a kind of water comprehensive water processor, and major function is to remove water body recovery technology, particle
Thing, purifies water, and reduces system dirt, bacterium algae, iron rust etc. and produces.
Existing Metal film type pressure differential filter includes body, filtration system, backwashing system, transmission system and drainage.Instead
The backwash water jet and corresponding pollution-absorbing nozzle set in system is washed, backwash water jet is consistent with pollution-absorbing nozzle size shape,
The water that backwash water jet sprays in backwash process is in spurting, and the backwash water and impurity that pollution-absorbing nozzle can not will transmit through filter screen are timely
Thoroughly suction is, it is necessary to which the multiple back and forth movement of backwashing system carries out backwash to filter screen, and the backwash time is long, makes screen pack flux can not
Recover in time, therefore limit filter efficiency and filter effect.
The content of the invention
Backwashing system and drainage are combined it is an object of the invention to provide one kind, backwash sewage is discharged in time, subtract
Few backwash time, the Metal film type pressure differential filter for improving filter efficiency.
For achieving the above object, the technical solution adopted in the present invention is：Metal film type pressure differential filter, including machine
Body, the filtration system in body, the backwashing system in filtration system, the transmission system being connected with backwashing system, position
In the drainage in filtration system；Filtration system is the tube structure with mesh, including the coarse filtration network segment and the fine filtering network segment, coarse filtration
A dividing plate is connected between net and fie screen two ends to body inwall, the backwashing system includes and concentric hollow of body
Axle, the hollow shaft front end is connected with transmission system, and hollow shaft front end is high-pressure water inlet chamber；High pressure backwashing pump is set to pass through high pressure
Backwashing pump water inlet pipe is supplied water into body, and high pressure backwashing pump is connected with body production water out, high pressure backwashing pump water inlet pipe and high pressure
Intake antrum is connected；The high pressure back purge system that high pressure water spray nozzle is provided with the outside of fie screen is connected with high-pressure water inlet chamber, institute
High pressure water spray nozzle is stated to be obliquely installed towards drainage；It is provided with hollow shaft on the inside of fie screen corresponding with high pressure water spray nozzle
Sewage discharge tube blowdown apparatus, the sewage discharge tube is more than close to high-pressure water inlet chamber end opening close to drainage end opening.
It is preferred that：Described high pressure water spray nozzle is in vertical direction with 10-30 ° of angle.
It is preferred that：It is connected including suction pump with drainage.Reduce the pressure of outlet of sewer, increase flusher and blowdown
Pressure differential between device, sewage is discharged in time in the presence of the normal pressure and suction pump negative pressure of high pressure backwashing pump.
It is preferred that：The sewage discharge tube is streamlined, and described streamlined rounded tail portion is towards drainage.Sewage discharge tube is streamline
Type, resistance is small so that sewage suction is more smooth, improves operating efficiency.
The invention has the advantages that：After such Metal film type pressure differential filter, high pressure water spray nozzle is tilted and set
Put, sewage discharge tube is corresponding and opening blowdown end is more than water inlet end, in backwash process, and high pressure water spray nozzle tilts injection water under high pressure
Backwash is carried out to fie screen, backwash water and debris, which are tilted, to be sprayed, pre-small post-large sewage discharge tube can by the backwash water of spurting and
Debris is efficiently and thoroughly sucked, and is discharged by drainage, and it is small that backwash process lasts short, water consumption, can quick-recovery initial shape soon
State.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is schematic diagram when body of the present invention is in cleaning state；
Fig. 3 is preferred embodiment for the present invention structural representation.
Embodiment
Show as shown in Figure 1, Figure 2, Metal film type pressure differential filter, including body 1, the filtration system 2 in body 1, be located at
2 backwashing system 3, the transmission system 4 being connected with backwashing system 3, the drainage 5 in filtration system 2 in filtration system；
Filtration system 2 is the tube structure with mesh, including 22 sections of 21 sections of coarse strainer and fie screen, coarse strainer 21 and the two ends of fie screen 22
Between be connected with a dividing plate to body inwall, backwashing system 3 includes the hollow shaft 31 concentric with body 1, the front end of hollow shaft 31
It is connected with transmission system 4, the front end of hollow shaft 31 is high-pressure water inlet chamber 32；High pressure backwashing pump 33 is set to pass through high pressure backwash pump water inlet
Pipe 34 is supplied water into body 1, and high pressure backwashing pump 33 is connected with the production water out 10 of body 1, high pressure backwashing pump water inlet pipe 34 and high pressure
Intake antrum 32 is connected；The high pressure back purge system 35 and high-pressure water inlet chamber of high pressure water spray nozzle 36 are provided with the outside of fie screen 22
Connection 32, the high pressure water spray nozzle 36 is obliquely installed towards drainage 5；The inner side of fie screen 22 is provided with hollow shaft 31
The blowdown apparatus 38 of sewage discharge tube 37 corresponding with high pressure water spray nozzle 36, the sewage discharge tube 37 is more than close to the end opening of drainage 5
Close to the end opening of high-pressure water inlet chamber 32.
Preferably embodiment is；Described high pressure water spray nozzle is in vertical direction with 10-30 ° of angle.Suction pump and blowdown system
System connection, reduces the pressure of outlet of sewer, and sewage is timely in the presence of the normal pressure and suction pump negative pressure of high pressure backwashing pump
Discharge.As shown in Figure 3, sewage discharge tube is streamlined, and described streamlined rounded tail portion is towards drainage, fairshaped sewage discharge tube
Resistance is small, and backwash sewage and debris are smoothly sucked by sewage discharge tube, reduces the backwash time, improves operating efficiency.
With deposition of the various pollutants on the inside of fie screen 22 in filter process, filtration channel is blocked, Inlet and outlet water
Pressure difference gradually increases, when pressure difference reaches pre-set value, system automatic start transmission system 4 and high pressure backwashing pump 33, power train
