Abstract
The utility model provides a sieve-plate type multi-functional filter which belongs to the field of sewage treatment dedicated devices used in oilfields, comprising an upper sealing head, a tank cylinder, a lower sealing head, a swirling flow device, an inclined plate degreasing unit, and a nut shell filtering material layer. The utility model is characterized in that the sieve-plate type multi-functional filter is provided with an upper sieve plate, a lower sieve plate and a plurality of circulating flow jetting nozzles. Wherein, the upper sieve plate is arranged on the lower part of the upper sealing head and on the upper part of the nut shell filtering material layer, and the lower sieve plate is arranged on the upper part of the lower sealed head and on the lower part of the nut shell filtering material layer; a plurality of linear through holes are distributed homogeneously on the surfaces of the circuit plate-shaped upper and lower sieve plates, and a plurality of circulating flow jetting nozzles are distributed on the lower sieve plate homogeneously and penetrate through the lower side of the lower sieve plate, extending to the nut shell filtering material layer. The utility model has the advantages of homogeneous water distribution, strong bearing ability, long operation cycle, and low failure rate. Besides, no blind spot exists during the backwashing process.
Description
Technical field
The utility model relates to a kind of sieve-board type multi-functional filter, belongs to disposing polluted water in oil special equipment field.
Technical background
Generally adopt the filter of shell medium in oil field sewage treating equipment, its major advantage is that the shell medium has stronger adsorption capacity, and anti-pressure ability is strong, wearability is good, can backwash and regeneration, operating cost is low.In the practical application at the scene, carrying the catchmenting of shell, the general employing by the sieve sheet of stainless steel wire establishment of water-distributing device are made, and under water inlet and backwash water outlet repeated stock, sieve sheet and promptly produce flexural deformation in a short time, the filtrate leakage phenomena occurs, cause the water quality can't be up to standard.The patent No. be 01202850.9 " multi-functional oilfield sewage filter " provide a kind of by welding, sintering, braiding, Wrapping formed metal chimney filter as catchment, the technical scheme of water-distributing device.The patent No. be 00124592.9 " stripping two-way filter " provide a kind of screen drum with stainless steel tube processing as catchment, the technical scheme of water-distributing device.Such scheme all exists common shortcoming, that is: water distribution is inhomogeneous, and the parts pressure-bearing is inconsistent, and the high parts of pressure-bearing damage easily.
Summary of the invention
The purpose of this utility model be substitute with sieve plate of the prior artly catchment, water-distributing device, guarantee all even raising bearing capacity of water distribution with this, thereby reduce fault rate.
The purpose of this utility model is achieved through the following technical solutions: a kind of sieve-board type multi-functional filter is made up of upper cover, jar tube, low head, swirling device, swash plate degreasing unit, shell filter material layer.Its special character is to have a upper sieve plate, following sieve plate, several circulation jet nozzles.
Described upper sieve plate is characterized in that being positioned at upper cover bottom, shell filter material layer top, and profile is a rondelle, and the surface is evenly distributed with several linear through holes.
Described sieve plate down is characterized in that being positioned at low head top, shell filter material layer bottom, and profile is a rondelle, and the surface is evenly distributed with several linear through holes.
Described circulation jet nozzle is characterized in that being uniformly distributed in down on the sieve plate, and passes from following sieve plate downside, probes into the shell filter material layer.
The utility model compared with prior art its advantage is: water distribution is even, and backwash does not have the dead angle, and bearing capacity is strong, and the cycle of operation is long, and fault rate is low.
Description of drawings
Fig. 1 vertically partly cuts open structural representation for the utility model.
Fig. 2 is the structural representation of (or down) sieve plate on the utility model.
Comprise among the figure: circulation jet nozzle 1, following sieve plate 2, shell filter material layer 3, upper sieve plate 4, swash plate degreasing unit 5, swirling device 6, upper cover 7, jar tube 8, low head 9, linear through hole 10.
The specific embodiment
Below in conjunction with the part specific embodiment, be described further with regard to design feature of the present utility model.
A kind of sieve-board type multi-functional filter, Fig. 1 can be used as the schematic diagram of a kind of specific embodiment of the present utility model, and its architectural feature is: upper cover 7, jar tube 8, low head 9 constitute housing of the present utility model.Upper sieve plate 4 is positioned at the bottom of upper cover 7, the top of shell filter material layer 3, and following sieve plate 2 is positioned at the top of low head 9, the bottom of shell filter material layer 3.Upper sieve plate 4, following sieve plate 2 can be made with stainless steel materials, utilize the laser micropore process technology on its surface, and processing 600 to 9000 width is that 0.2mm to 2mm, length are the linear through hole 10 of 10mm to 70mm.Playing evenly to be welded with on the sieve plate 2 three circulation jet nozzles 1 and passing, probe into shell filter material layer 3 from following sieve plate downside.Sewage at first enters swirling device 6 during filtration, oil particles in the sewage is fully collided, make profit, solid-liquid initial gross separation by swirling flow, assembling through swash plate degreasing unit 5 is the bulky grain oil droplet, float to oil drain out and discharge, sewage enters shell filter material layer 3 by the linear through hole 10 of upper sieve plate 4 and filters, and greasy dirt and mechanical admixture are also held back in 3 absorption of shell filter material layer, and the water after the purification flows out from outlet pipe through linear through hole 10 backs of sieve plate 2 down.
The utility model is by the mode of extracorporal circulatory system, and the backwash technique flow process of cooperating equipment is cleaned, and complete equipment can be according to on-site actual situations, adopts single jar or multiple tank to be used, and multiple tank can adopt the serial or parallel connection mode when using.
Claims (4)
