Abstract
The utility model relates to a water tank on a building top in construction. The middle part of the inner bottom surface of a water tank body is provided with a beveloid whose cross section is a triangle. The high end of the beveloid is arranged in the middle part inside the water tank body, and the lower end of the beveloid is arranged on one side of the inner bottom surface of the water tank body corresponding to a sewage draining port. A groove is formed between the high end of the beveloid and the lower part of the water tank body on the inner wall corresponding to a water outlet. A filtering net cage is movably suspended on the upper part of the groove, and the upper end of the filtering net cage is higher than the high end of the beveloid. A water inlet of the water tank body is connected with an extended water inlet pipe which is guided from the groove inside the water tank body.
Description
The utility model relates to a kind of water tank, particularly a kind of building roof water tank upstairs.
Existing building generally surpasses three layers, all is provided with roof water tank at roof, in order to solve high-rise user's drinking water problem.But the secondary pollution problem of roof water tank is puzzlement people's a social concern always, can not get for a long time solving.Because the water in the roof water tank can not in time be changed, can make the water quality variation, the bad problem of the ubiquitous closed performance of water tank often has dust storm, dust or foreign material to enter water tank in addition, produces suspension, the mushroom reproductive patterns appears, particularly summer, situation is even more serious, and these all can have a strong impact on the water quality in the water tank, cause secondary pollution, influence people's health.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of cost low, effective anti-secondary pollution roof water tank.
Technical solution of the present utility model:
A kind of anti-secondary pollution roof water tank, it includes retaining casing (1), casing (1) bottom one side is provided with and supplies water with delivery port (2), opposite side is provided with sewage draining exit (3), its top is provided with water inlet (4) and ball float sealing valve (5), it is characterized in that being provided with a cross section at retaining casing (1) inner bottom surface middle part is leg-of-mutton clinohedral (6), high-end casing (1) middle part that is positioned at of this clinohedral (6), its low side is positioned at a side of the corresponding sewage draining exit of casing (1) inner bottom surface (3), make to form a groove (7) between inwall one side of the high-end side of clinohedral (6) and the corresponding delivery port in casing (1) bottom (2), be hung with the filtration net cage (9) of filling filtering material (8) in the top movable of this groove (7).The upper end of this net cage (9) should exceed the high-end of clinohedral (6), and casing (1) top water inlet (4) locates to be connected with the water inlet pipe of extending (11) that causes in casing (1) internal channel (7).
The utility model can remove that tiny suspended particulate impurity and part bacterium organic matter also can reduce and removed principle with the turbidity of water in the water after according to water filtration, blowdown inclined-plane and filter in water tank, have been increased, make them organically combine, promptly accumulate in water tank sewage draining exit place after filtration is installed in retaining in the water tank after filtration like this, discharge from sewage draining exit at last by the blowdown inclined-plane.The utility model keeps the raw water box structure, it is ingenious that it increases the part-structure novelty, cost is low, can prevent and treat the secondary pollution at water source, and the water of cleaning is provided to the user, filter adopts cage structure, be convenient to cleaned and changedly, the water tank bottom of ramp type has the mudhole blowdown of being more convenient for, and the current during simultaneously ingenious utilization water inlet carry out backwash to filter, can recover the filter capacity of filtration beds quickly, effect is very good.
Fig. 1 is a structural representation of the present utility model.
As Fig. 1, the utility model can be equipped with the supporting layer (10) that is made of the rubble material in the bottom of the groove (7) in the water tank (1), filters net cage (9) and just is placed on this supporting layer (10).This supporting layer (10) can be used to support net cage (9) on the one hand, also forms the retaining space on the other hand.The filtering material (8) that filters in the net cage (9) can be an active carbon, also fine sand, and the mesh of net cage (9) is slightly less than the particle diameter of filtering material (8).And filter net cage (9) and can be the whole casing that matches with whole groove (7) size, also can be a plurality of small-sized net cages and be assemblied to form.
When the utility model is made, can be built into one high about 40 centimeters clinohedral (6) in retaining casing (1) bottom at about 2/3 place with cement and brick, the angled surfaces of this clinohedral (6) is this practical blowdown face, the sewage draining exit (3) of the just in time corresponding casing of its inclined-plane lowest part (1), so that make things convenient for blowdown, opposite side forms about 1/3 wide groove (7) in casing (1) like this, it is a filtering area of the present utility model, the bottom is equipped with the supporting layer (10) that is made of stone, cobble etc. in the district, and supporting layer (10) top is placed and filtered net cage (9).Like this water source from casing (1) top water inlet (4) by the water inlet pipe of extending (11) water filling in casing (1), when filling casing (1) till the action of its ball float sealing valve (5).During user's water, the water in the water tank (1) filtering material (8) in the net cage (9) after filtration filters the back and supplies with the user from casing (1) the bottom delivery port (2) of groove (7) one sides, and the water of cleaning is provided for the user.Dirt in the retaining casing (1) net cage (9) after filtration is attracted on the filtering material (8) after filtering, after considering that filtering material (8) holding filth capacity increases, water permeability meeting variation, so utilize the water inlet pipe (11) (when particularly night, hydraulic pressure was higher) when water inlet of extending that filtering material (8) is carried out backwash, make on the filtering material (8) the precipitation dirt automatically from the blowdown inclined-plane productive set that filters net cage (9) upper end edge clinohedral (6) in sewage draining exit (3), so that periodical blowdown, thereby make filtration beds recover filter capacity at short notice, improve its application life.In addition, because filtration net cage of the present utility model (9) be activity, openable shape, thus can periodically changed or cleaned filtering material (8), effect is very good, can guarantee to provide to the user all the time the drinking water of cleaning.
