Description
Technical field
The utility model relates to a kind of produced-water reinjection water injection pump rotary flow type filter; The filter screen that solves existing produced-water reinjection water injection pump filter is prone to stop up, stop up the back be prone to by water injection pump take out bad cause water injection pump water channel and impeller to stop up can not water filling and the problem of filter rinsed inconvenience.
Background technique
At present, the used filter of rejection of oil flied effluent water injection pump is old-fashioned filter, and filter screen all is the spile type filter screen, and current directly impact filter screen; Solid particle under the filter directly is squeezed in the opening of sieve, and the particle that particle diameter is big is filtered the filter bottom, and not long-time opening of sieve is almost blocked, and the deposit under in addition filtering is many more; The filter area of filter screen is more little, and it is more little to cross the water yield, causes to the oil transfer pump insufficient water; Produce certain negative pressure, meeting taken out filter screen bad, and granular solid is drawn in the pump and can expands impeller bad; Therefore water filling worker frequent filter rinsed aperiodically just owing to be to connect with bolt, must be laid down 12 bolts fully; Extract filter screen out, all pull out, change filter screen is cleaned again with the filter thing that handgrip filters out; Clean and once to filter wire stitcher and need more than 2 hour, labor intensity is big, befouling environment and influence normal water filling.
Summary of the invention
The utility model provides a kind of produced-water reinjection water injection pump rotary flow type filter, overcomes the defective that above-mentioned prior art exists.
The technological scheme of the utility model realizes in the following manner:
The utility model mainly is made up of strainer cover, flange plate, filter screen, housing, cyclone tube, inlet tube, outer pipe, ring type filter plate and blowdown valve; It is characterized in that housing is made as cylindrical shape; Be provided with the one big mouthful upwards downward cyclone tube of osculum at the middle part of housing; Filter screen that Stainless Steel Wire is made or that corrosion resistant plate is made is stamped in the cyclone tube upper-end surface; The lower end periphery is pressed with the ring type filter plate that corrosion resistant plate is made, and is provided with the taper filter thing storing cavity that big mouth makes progress between ring type filter plate and the housing bottom, and the outside is provided with drain pipe and blowdown valve at the bottom of filter thing storing cavity bottom to housing; Be provided with that be connected with cyclone tube and the inlet tube housing welding on right side, housing middle and upper part, the left side is welded with outer pipe, and the housing upper end is welded with flange plate, is connected with quick connecting bolt with strainer cover; On the outer circumferential face of filter screen, be provided with positioning cylinder vertically upward, the positioning cylinder upper end is suitable for reading concordant with housing, and positioning cylinder is provided with intercommunicating pore.
Cyclone tube import pipe end and the welding of cyclone tube tangential, the other end cyclone tube inlet tube is connected with the sealing inserting mode with the inlet tube of housing.
Filter screen and housing, annular filter plate and housing are sealing and flexibly connect, and filter screen and annular filter plate and cyclone tube and taper filter thing storing cavity are flexible connection, taper filter thing storing cavity and housing welding.
Compared with present technology the utility model has the following advantages:
1, with cyclone tube the solid particle in the return water is separated, with filter screen the floating thing in county in the return water is separated again, make filter screen be difficult for stopping up, and avoided the impact of current, prolonged the Cleaning period of filter screen and the working life of filter screen.
2, maintenance replacing filter screen and cyclone tube are efficient and convenient, only need dozens of minutes just can accomplish, and do not influence water filling.
3, granular substance can not get in pump chamber and the impeller under the filter, pump chamber and impeller can not take place stop up, and has prolonged the working life of pump.

Embodiment
For further disclosing the technological scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
The utility model mainly is made up of strainer cover 2, flange plate 5, filter screen 3, housing 9, cyclone tube 6, inlet tube 7, outer pipe 11, ring type filter plate 8 and blowdown valve 10; It is characterized in that housing is made as cylindrical shape; Be provided with the one big mouthful upwards downward cyclone tube of osculum at the middle part of housing; Filter screen that Stainless Steel Wire is made or that corrosion resistant plate is made is stamped in the cyclone tube upper-end surface; The lower end periphery is pressed with the ring type filter plate that corrosion resistant plate is made, and is provided with the taper filter thing storing cavity that big mouth makes progress between ring type filter plate and the housing bottom, and the outside is provided with drain pipe and blowdown valve 10 at the bottom of filter thing storing cavity bottom to housing; Be provided with that be connected with cyclone tube and the inlet tube 7 housing welding on right side, housing middle and upper part, the left side is welded with outer pipe 11, and the housing upper end is welded with flange plate 5, is connected with quick connecting bolt 1 with strainer cover.
When using the utility model, connect on the inlet line of produced-water reinjection water injection pump, come water to pass through housing 9 upper inlet pipes 7 and get into cyclone tube 6; Solid particle in the sewage falls into filter thing storing cavity along the eddy flow tube wall, and sewage returns out the annular chamber between entering cyclone tube and the housing through filter screen, gets into the produced-water reinjection water injection pump from outer pipe 11 again; Sewage does not basically just have solid particle to guarantee the normal water filling of water injection pump after two-stage is separated, and solid particle under the filter and the big colloid of quality are gone through blue or green matter and discharged from blowdown and 13, are discharged in the oil drum; Transport and get final product; When changing filter screen, unscrew the nut on the quick connecting bolt 1, unload strainer cover to quick connecting bolt toward next pendulum like need; Just take out filtering square, filter screen just can be changed.If replacing cyclone tube; Cyclone tube is moved the disengagement socket to the first from left just can take out replacing to cyclone tube; Also can propose the ring type filter plate to change simultaneously, the dismounting filter be efficient and convenient with each parts of changing filter screen and replacing filter interior, has guaranteed the separating effect of filter; This structure of filter is novel, has filled up the blank of this technical field.
