Abstract
The utility model relates to a pollution discharging apparatus for a filtering pot (tank), which is characterized in that the top part of the filtering pot (tank) is designed into a conical shape, and an upper opening is added with a cover to form a pollution collecting cavity. Under the upward supporting action of waterpower, pollutants which are washed back rapidly converge at the top part of the filtering pot (tank) through a conical surface, and then, the pollutants are discharged via the pollution collecting cavity. Since the dimension of a conical top opening can be designed to be very small, the pollution discharging time and the water consumption are reduced in multiples, and the pollution discharge is more thorough. The utility model can be used for the structure design of the novel filtering pot (tank) and for the technical reconstruction of the existing filtering pot (tank), thereby, the utility model economically solves the disadvantage of the existing filter that a filtering material is easy to harden to be ineffective.
Description
One, technical field
The utility model relates to the blowdown apparatus of clean process again of a kind of hay tank (pond) filtrate backwash in the purification of water quality engineering.
Two, background technology
Impurity such as oils in the water, suspended substance can be effectively stopped in filtration, have been widely used in water purifying treatment engineering.The retaining power of filtrate and filtrate feature and the water quality that is filtered, the water yield are relevant.When the water yield of filtrate obstruction reaches certain value, need to adopt the mode of counterflush that the pollutant removal of obstruction in filtrate fallen, to reach the clean again purpose of filtrate.The hay tank (pond) that uses is when pollutent is removed in back flushing at present, adopt the excessive row's mode of gross area, because the area of blow-off pipe is much smaller than filtration area (both ratio be about 1: 150～200), add and do not collect dirty device, cause excessive row's time of back flushing long, the water consumption is big, and pollutant removal is unclean.
It is in the strainer upper inside wall that patent No. ZL00224249.4 " is equipped with the strainer of dirt collecting bucket ", a taper bucket is housed, cover in the water inlet pipe outlet, can effectively collect the dirt that back flushing produces, make it rapid emptying, the backwashing time and the water yield can save 50%, confirm to truly have above-mentioned effect by producing to use, but because dirt collecting bucket is contained in the strainer, limited by scantlings of the structure, the dirt collecting bucket water-outlet area can not be too little, so backwash blowing time and water loss are still bigger than normal.
Three, summary of the invention
The purpose of this utility model is that the top design of hay tank (pond) is tapered, and covering suitable for reading forms the dirty chamber of collection; The pollutent that backwash goes out is collected to the top rapidly by the conical surface under waterpower pop-up effect, through collecting the emptying of dirty chamber.Because it is very little that vertex of a cone mouth size can be designed to, and blowing time and water loss are reduced at double, blowdown is more thorough.This device can be used for the structure design of new hay tank (pond) and the technological transformation of existing hay tank (pond), thereby has solved the existing defective that easily hardens and lost efficacy with filter leaching material cost-effectively.
The blowdown apparatus that the utility model provides is characterized in that the top design of hay tank (pond) tapered, and covering suitable for reading forms the dirty chamber of collection, can dwindle the row's area that overflows to greatest extent, thereby effectively shorten the row's time of overflowing, and reduces water loss, improves the clearance of pollutent.The awl base angle of top tapered is generally 45 °, also can be greater than or less than this value.
Four, description of drawings
Fig. 1, the hay tank elevation cross-sectional view of blowdown apparatus is housed;
Fig. 2, the filtering basin elevation cross-sectional view of blowdown apparatus is housed;
Among the figure: 1-top tapered bucket; The 2-filter material layer; The dirty chamber of 3-collection; The 4-vacuum breaker valve; The 5-water intaking valve; The 6-outlet valve; 7-back flushing water inlet (air inlet) valve; 8-back flushing outlet valve; 9-liquid level mirror.
Five, embodiment
As shown in Figure 1 and Figure 2 on top tapered bucket 1, be covered with the dirty chamber 3 of collection, close water intaking valve 5 during back flushing, when water level is reduced to when exceeding filter material layer 2 about 100～300mm (can be demonstrated by liquid level mirror 9), close outlet valve 6, open back flushing water inlet (air inlet) valve 7, feed pressurized air, air purge 3～5 minutes earlier, open back flushing outlet valve 8, air water is united flushing 1～3 minute again, the flushing of last water separately, up to pollutent till collecting the emptying of dirty chamber.In the time of outside the hay tank internal pressure is lower than jar, top vacuum breaker valve 4 can be opened automatically, and the draining circulation that guarantees to overflow is smooth.
(annotate: the ratio of the filtration area of top tapered bucket water-outlet area and hay tank (pond) is generally 2%～5%.)
Claims (2)
1, hay tank (pond) blowdown apparatus is characterized in that the top design of hay tank (pond) taperedly, and covering suitable for reading forms the dirty chamber of collection, can dwindle the backwashing water row's area that overflows to greatest extent.
2, blowdown apparatus as claimed in claim 1 is characterized in that boring base angle, is generally 45 °, also can be greater than or less than this value.
