Abstract

The utility model relates to an all-plastic hydrosphere tank which can uniformly distribute water and air. The utility model is composed of an oblong plastic box body and two plastic tilting plates arranged in the box body, wherein both ends of the box body are ringent, and each of the plastic tilting plates is in a shape like the Chinese character 'ba'; the plastic tilting plates and the oblong plastic box body are integrated through injection molding, and pinholes are uniformly distributed on the top surface of the plastic box body and the plastic tilting plates; a plurality of hydrosphere tanks are connected together to be arranged in a water pool to filter water supplied or to clean filtration media in a reverse direction. The utility model has the advantages of uniform hydrosphere distribution, high flushing strength, no dead angle, no filter layer disturbance, light weight, firmness and durability, and thus, realizes the effects of saving water, guaranteeing water quality and extending the service life of each of the filtration media.

Description

Overall plastic aqueous vapor case

Technical field

The utility model relates to the cleaning device of filter 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.

Technical background

At present, the cleaning device of filter 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 out-of-flatness causes filter 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 little determining to splice, cause bulk strength not enough, cause in use, when water, meeting " spring pond " when large-minded.

Technical scheme

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 reinforcement, several aqueous vapor casees link together and are tiled in the filtered water reservoir, can water supply be filtered by the filter medium that is laid on the casing top, or oppositely filter medium is cleaned.

Owing to adopt such scheme, the aqueous vapor that can evenly distribute helps medium and cleans; Flushing great efforts, no dead angle, and don't disturbance filter course; In light weight, sturdy and durable, thus reach water-saving, guarantee water quality and prolong the filter medium effect in service life.

The specific embodiment

Provide the detailed embodiment of overall plastic aqueous vapor case below in conjunction with Figure of description.

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 reinforcement (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 filter 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, the aperture is 5 millimeters, also is evenly distributed with aperture on the plastics swash plate, and its aperture is 4.5 millimeters, box bilateral wall is provided with and connects the age of a draught animal (5), several aqueous vapor casees laterally linked together by the age of a draught animal, and when water supply was filtered, water oozed from the filter medium that end face is laid down and through the aperture on the end face and flows into the aqueous vapor case, again at the bottom of the skewback aperture flows into case, finally conflux into water leg, reach the purpose of filtered water by the casing front end.During backwash, 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, filter medium is cleaned, the pressure that casing can bear is 〉=1.5kg/cm.

Claims

1. 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 reinforcement, and the two side is provided with and connects the age of a draught animal.

3. overall plastic aqueous vapor case according to claim 1 is characterized in that: the small aperture on rectangle plastic box end face and the plastics swash plate can 3.5 millimeters-6 millimeters.
