Abstract
The utility model discloses a convection scrubbing structure for a filter material in a pressure filter tank, which is characterized in that a water distribution and gas distribution main tube (1) is installed on the upper part of the filter layer of the filter tank; a distribution cavity (2) is connected to the water distribution and gas distribution main tube, and a plurality of water distribution and gas distribution branch tubes (3) with different lengths are uniformly welded in the circumferential direction of the distribution cavity (2); and sieve tubes (4) are welded on the end parts of the water distribution and gas distribution branch tubes (3), and the sieve tubes (4) are inserted in the filter layer. Compressed air or water enters in the distribution cavity (2) via the water distribution and gas distribution main tube (1) and is subjected to pressure stabilization in the distribution cavity (2); the compressed air or the water is uniformly conveyed into the water distribution and gas distribution branch tubes (3) and then enters in the filter layer in the filter tank via the sieve tubes (4); and collision among the particles of the filter material is enhanced via the impact action of air or waterpower, so that oil stains or suspended particles attached to the surface of the filter material are separated out.
Description
One, technical field
The utility model relates in the purification of water quality engineering convection current of a kind of pressure filter tank filtrate and washes structure by rubbing with the hands.
Two, background technology
Media filtration can effectively be stopped oils and suspended contamination in the water; Be widely used in already in the purification of water quality treatment project; When the pollutant of filtrate obstruction reaches a certain amount of, need carry out backwash the pollutant removal of obstruction in filtrate fallen, to reach the clean again purpose of filtrate.When existing filtering tank is removed pollutant in backwash; The main mode of bottom water inlet or air inlet that adopts is carried out backwash, because hydraulic action and air stirring effect are not enough, filtering layer middle and upper part filtrate can't obtain effective backwash; Cause filtering layer seriously polluted, the inefficacy of hardening of last filtrate.
Three, summary of the invention
The purpose of the utility model: be on the top of filtering tank filtering layer the filtrate convection current to be installed to wash structure by rubbing with the hands, the screen casing (4) of convection current being washed by rubbing with the hands structure inserts in the filtering layer.When compressed air or water are responsible for (1) and are got into distribution cavity (2) through water distribution, distribution; Voltage stabilizing in distribution cavity (2); Uniformly compressed air or water are sent into water distribution, distribution arm (3); Get in the filtering layer of filter interior through screen casing (4) again, utilize the percussion of air or waterpower to strengthen the collision between filtering material particle, the greasy dirt or the suspended particulate that adhere to filter material surface are separated.
The utility model is characterized in that: a water distribution, the distribution person in charge (1) are installed on filtering tank filtering layer top; Connect a distribution cavity (2); Distribution cavity (2) is at evenly some water distributions different in size of welding of circumferencial direction, distribution arm (3); Water distribution, distribution arm (3) end welding screen casing (4), these screen casings (4) insert in the filtering layer.
Four, description of drawings
Fig. 1 is the utility model elevation cross-sectional view
2-distribution cavity 3-water distribution is responsible in 1-water distribution among the figure, distribution, the 4-screen casing is responsible in distribution
Five, the specific embodiment
One water distribution, the distribution person in charge (1) are installed on filtering tank filtering layer top; Connect a distribution cavity (2); Distribution cavity (2) circumferencial direction evenly welds 9～15 water distributions different in size, distribution arm (3), water distribution, distribution arm (3) end welding screen casing (4), and these screen casings (4) insert in the filtering layer.
During the filtering tank backwash; Compressed air or water are through water distribution, when (1) entering distribution cavity (2) is responsible in distribution; Voltage stabilizing in distribution cavity (2) is sent compressed air or water into water distribution, distribution arm (3) uniformly, gets in the inner filtering layer of filtering tank through screen casing (4) again; Utilize the percussion of air or waterpower to strengthen collision, friction between filtering material particle, the greasy dirt or the suspended particulate that adhere to filter material surface are separated.
Claims (1)
1. structure is washed in pressure filter tank filtrate convection current by rubbing with the hands; It is characterized in that: a water distribution, the distribution person in charge (1) are installed on filtering tank filtering layer top; Connect a distribution cavity (2); Distribution cavity (2) is at evenly some water distributions different in size of welding of circumferencial direction, distribution arm (3), and water distribution, distribution arm (3) end welding screen casing (4) are in these screen casings (4) insertion filtering layer.
