Abstract

The invention relates to a reverse swirl filter, and belongs to the field of water treatment. The reverse swirl filter comprises a shell, water inlet(s), a spacing ring, a lower screen plate, an upper screen plate, a water outlet, a filtering material, a lower grating, a sewage outlet, a sludge chamber, a swirl chamber, a filtering chamber and a water outlet cavity, wherein the shell is a pressure vessel provided with an upper sealing head and a lower sealing head, the upper plane of the spacing ring is in seal welded connection with the shell, the lower grating is in welded connection with the shell, the upper screen plate is hermetically connected with the barrel wall of the shell in a sliding manner, the lower screen plate is fixed on the spacing ring in a bolted connection manner, every two adjacent chambers of the sludge chamber, the swirl chamber, the filtering cavity and the water outlet chamber are communicated, and the water inlet(s) is/are formed circumferentially and tangentially. The large grained impurities settle firstly under the swirling flow, the intercepted suspension automatically drops out during the filtering process under the agitation of swirling flow, the filter bed is not blocked easily, and the backwashing cycle is prolonged relatively, therefore, the reverse swirl filter is less in water consumption, low in energy consumption, simple in structure, low in production cost and low in running cost, and can be widely used for primary filtering of water.

Description

A kind of eddy flow inverse filter

[technical field]

The present invention relates to a kind of eddy flow inverse filter, the various suspensions for separating of in the water belong to water-treatment technology field.

[background technology]

Traditional sand filter, more medium filter, fabric filter etc., the general water of filter type is all walked from top to bottom, suspension in the water is intercepted at the surface of filter bed, and filter bed is easy to stop up, will backwash after stopping up, backwashing period is short, and water consumption is big, and energy consumption is big.

[summary of the invention]

At the deficiency that occurs in above-mentioned, the purpose of this invention is to provide the filter that a kind of water treatment is used, can make oarse-grained impurity automatic sedimentation, the suspension that is blocked in filtration comes off automatically, and filter bed is not easy to stop up like this, backwashing period prolongs relatively, water consumption just can descend, and energy consumption also can descend, and is simple in structure, production cost is low, and operating cost is few.

The present invention to achieve the above object, on the basis of the traditional sand filter of contrast, invented a kind of eddy flow inverse filter, by housing, water inlet, cage ring, following sieve plate, upper sieve plate, delivery port, filter material, following barrier, sewage draining exit, the mud chamber, the eddy flow chamber, filter chamber, water chamber is formed, housing is a kind of pressure vessel of going up low head, last plane and the housing of cage ring is that seal welding connects, following barrier connects with the housing welding, upper sieve plate is that slipper seal connects with the barrel wall of housing, following sieve plate is fixed on Bolt Connection on the cage ring, the mud chamber, the eddy flow chamber, filter chamber, adjacent two chambeies of water chamber communicate, it is characterized in that: the water inlet in the eddy flow inverse filter is the tangential setting of circumference, the number of water inlet 〉=1.

Above-mentioned eddy flow inverse filter is characterized in that: the screen face of following barrier and the angular range of vertical line are 0-30 °.

[description of drawings]

Accompanying drawing 1: eddy flow inverse filter structural representation.

Accompanying drawing 1 is depicted as embodiments of the invention.

[specific embodiment]

Be further described below in conjunction with 1 pair of embodiments of the invention of accompanying drawing: the eddy flow inverse filter is by housing 1, water inlet 2, cage ring 3, following sieve plate 4, upper sieve plate 5, delivery port 6, filter material 7, following barrier 8, sewage draining exit 9, mud chamber 10, eddy flow chamber 11, filter chamber 12, water chamber 13 is formed, filter material 7 usefulness be rotor type fibre filtering material, housing 1 is a kind of pressure vessel of going up low head, water inlet 6 is the tangential settings of circumference, last plane and the housing of cage ring 3 is that seal welding connects, the former water that water inlet 6 enters is in eddy flow mud chamber 10, can form eddy flow in the chamber 11, oarse-grained impurity is sedimentation in advance under the eddy flow action of centrifugal force, process barrier 8 down enters mud chamber 10, the screen face of following barrier 8 and the angle of vertical line are 0-30 °, favourable impurity falls into mud chamber 10 smoothly, the former water that enters eddy flow chamber 11 enters filter chamber 12 by following sieve plate 4, following sieve plate 4 is to be fixed on welding connection on the cage ring 3, following sieve plate 4 plays support filter material 7, mud chamber 10 and eddy flow chamber 11 communicate, eddy flow chamber 11 and filter chamber 12 communicate, filter chamber 12 and water chamber 13 communicate, the rotor type fibre filtering material of filter chamber 12, the interception of suspension in the water is filtered below filter bed, clear water after the filtration enters water chamber 13 by upper sieve plate 5 and is discharged by delivery port 6, upper sieve plate 5 is that slipper seal connects with the barrel wall of housing 1, can play compacting rotor type fibre filtering material 7, thereby raising filtering accuracy, suspension can increase thickening gradually below filter bed along with the prolongation of filtration time is tackled, automatically sedimentation comes off under the stirring of eddy flow power, process barrier 8 down enters mud chamber 10, thereby prolonged the cycle of backwash, the mud in mud chamber 10 is regularly discharged by sewage draining exit 9, following barrier 8 is fixedly connected with housing can effectively reduce eddy flow water to the agitaion of mud, water is to enter sewage draining exit 9 from delivery port 6 to discharge during backwash, water inlet 2 is closed, forward and back flush hocket and repeatedly just filter material can be washed in only, thereby finished a filter cycle, added the effect that compressed air can strengthen backwash greatly during backwash in the water simultaneously.

When filter material 7 was sand, the space of sand filter bed distributed from bottom to top for from large to small, and the oarse-grained impurity hurdle of going ahead of the rest cuts, and short grained impurity continues uply to be cut by the hurdle, and sand filtration at this moment is in-depth filtration, has improved sand filtering efficiency.

Also can hang elastic filler between sieve plate 4 and the following barrier 8 down, the gathering of favourable suspended impurity is sunk, and alleviates the burden of filtrate 7, can effectively prolong filter cycle, improves filter efficiency.

The eddy flow inverse filter with can make oarse-grained impurity automatic sedimentation under the effect of eddy flow, impurity heavy meeting under the effect of eddy flow is lost to the outer ring, the light circle core shaft place that compiles, the suspension progressive additive that is blocked in the filtration and coming off automatically, filter bed is not easy obstruction like this, backwashing period prolongs relatively, water consumption just can descend, and energy consumption also can descend, and the eddy flow inverse filter is simple in structure, production cost is low, and operating cost is few.
