Abstract

The utility model relates to a plastic water tank which can uniformly distribute water and air. The utility model is composed of a rectangular plastic box body with two open ends and two V-shaped plastic sloping plates in the rectangular plastic box body, wherein the plastic sloping plates and the rectangular plastic box body are molded into one body. Small holes are uniformly distributed on the top surface of the plastic box body and the plastic sloping plates, and a plurality of water and air box are connected together and are arranged in a water pool to filter the supplied water or clean filter media in reverse direction. The utility model can distribute water and air uniformly, and has the advantages of large washing force, no dead angle, no disturbance of filter layer, light weight, firmness and high durability. Therefore, the utility model achieves the effect of saving water, keeping a good water quality and prolonging the service life of the filter media.

Description

Overall plastic aqueous vapor case

The utility model relates to the washing unit of filtration medium in a kind of water supply and sewage filter tank, the overall plastic aqueous vapor case of particularly a kind of energy uniform water distribution distribution.

At present, the washing unit of filtration medium generally adopts the hollow filter block of potter's clay in the water supply and sewage filter tank, and its aperture is inconsistent, water distribution is inhomogeneous, can only water flowing can not ventilate, and because of unfairness causes filtration medium fluctuating is arranged, and heavy, frangible, poor filtration effect.Recently also there is the plastic material of employing to replace, owing to be not the slit that is connected with of integral molded plastic or " Eight characters plate " and rectangular tube, thereby influenced the gentle control of water in the backwash process, again owing to limited by material therefor, and adopt fritter to splice, cause bulk strength not enough, cause in use, when water, meeting " spring pond " when large-minded.

The purpose of this utility model provides a kind of overall plastic aqueous vapor case that improves structure, make its volume increase, rational in infrastructure, material is firm, once injection moulding, easy to install, with the gentle cleaning and filtering medium of few water.

The purpose of this utility model is realized by following technical scheme: rectangle plastic box and inner two " eight " font plastics swash plates by the two ends opening constitute, plastics swash plate and rectangle plastic box are injected into one, be distributed with aperture on its end face and the swash plate, small aperture can 3.5 millimeters-6 millimeters, two sides side plate and base plate are formed the aqueous vapor case in the lump, two ends is a splice ends, four sides of aqueous vapor case are equipped with stiffening web, several aqueous vapor casees link together and are tiled in the filtered water reservoir, can water supply be filtered by the filtration medium that is laid on the casing top, or oppositely filtration medium is cleaned.

Owing to adopt such scheme, can the uniform distribution aqueous vapor, help medium and clean; Flushing great efforts, no dead angle, and don't disturbance filtering layer; In light weight, sturdy and durable, thus reach water-saving, guarantee water quality and prolong the filtration medium effect in work-ing life.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is overall plastic aqueous vapor case side elevational view.

Fig. 2 is overall plastic aqueous vapor case end view drawing.

Fig. 3 is the pre-face figure of overall plastic aqueous vapor case.

Number in the figure is described as follows:

1, casing 2, side panel 3, aperture

4, stiffening web 5, the age of a draught animal

At Fig. 1, Fig. 2, among Fig. 3, overall plastic aqueous vapor box body (1) is made of rectangle plastic box and inner two " eight " font plastics swash plates (2) of two ends opening, contour dimension is 300 * 330 * 650mm, one end of rectangle plastic box extends the grafting edge of inside contraction, the other end extends abducent socket edge, plastics swash plate and rectangle plastic box are injected into one, and be provided with stiffening web (4) in wall, size according to the filter tank, several overall plastic aqueous vapor casees can be plugged on together in two ends, be evenly distributed with aperture (3) on the plastic box end face, its hole count what and pore size are by the proportion of the filtration medium of end face laying, thickness and backwash rate decision are when medium is a quartz sand, the backwash rate of water is 46L/SM ², gas backwash rate be 1416L/SM ²The time, hole count is 68, and the aperture is 5 millimeters, also is evenly distributed with aperture on the plastics swash plate, its aperture is 4.5 millimeters, box bilateral wall is provided with and connects the age of a draught animal (5), and several aqueous vapor casees laterally linked together by the age of a draught animal, when water supply is filtered, water oozes from the filtration medium that end face is laid down and through the aperture on the end face and flows into the aqueous vapor case, at the bottom of the skewback aperture flows into case, finally conflux into water leg again, reach the purpose of filtered water by the casing front end.During back flushing, have that the water of certain pressure is gentle to enter the aqueous vapor case from the casing front end, enter the top aperture from the skewback aperture again, filtration medium is cleaned, the pressure that casing can bear is 〉=1.5kg/cm.

Claims

1, a kind of overall plastic aqueous vapor case, rectangle plastic box and inner two " eight " font plastics swash plates by the two ends opening constitute, it is characterized in that: an end of rectangle plastic box extends the grafting edge of inside contraction, the other end extends abducent socket edge, plastics swash plate and rectangle plastic box are injected into one, are evenly distributed with aperture on its plastic box end face and the plastics swash plate.

2, overall plastic aqueous vapor case according to claim 1, it is characterized in that: the wall of rectangle plastic box is provided with stiffening web, and the two side is provided with and connects the age of a draught animal.
