Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, specifically a water distribution device of water collecting tank cover plate. BACKGROUND

[0002] The S-shaped filter brick is a kind of high-efficiency, environmental protection filter material, and is widely applied to water treatment field;It adopts special S-shaped structure design, so that the filter brick has greater filtration area and higher filtration efficiency in the filtration process, thereby improving the treatment capacity of the entire denitrification filter tank;

[0003] The S-shaped filter brick is usually designed as the structure of upper air and lower water, the upper part is backwashing air hole, and the lower part is water distribution system, and the treated water enters the filter tank by gravity permeation, is filtered after sand layer and pebble layer, and is evenly distributed to the entire filter tank by the water distribution and air distribution hole and water hole in the upper part of the filter brick;The upper air and lower water structure design in the S-shaped filter brick ensures that backwashing water and gas are evenly distributed at each diffusion hole of the entire filter tank backwashing air-water distribution system;The filtered water is collected by the gap formed by the top corner of the filter brick and the water collecting hole in the bottom of the filter brick, and is discharged to the clean water tank by water outlet pipe of water collecting channel;

[0004] Among them, the water distribution uniformity of the water distribution system of the denitrification deep-bed filter tank greatly influences the backwashing effect, and uneven water distribution can cause insufficient expansion of part of filter layer, and excessive expansion of another part of filter layer, in the insufficient expansion area, filter material is not cleaned, in the excessive expansion area, "sand running" is caused, when the supporting layer pebble moves, "sand leakage" phenomenon is caused.

[0005] However, the conventional water distribution device has poor water distribution uniformity, and is inconvenient to install with the S-shaped filter brick. INVENTION CONTENTS

[0006] The utility model discloses a water distribution device of water collecting tank cover plate to solve the problems in the background art.

[0007] To achieve the above object, the utility model provides the following technical scheme:

[0008] A water distribution device of water collecting tank cover plate, including bottom plate, the upper end of the middle part of bottom plate is provided with water distribution port, and is set up with adjusting hole in the four corners of bottom plate.

[0009] As a further scheme of the utility model: the bottom plate and water distribution port are all stainless steel components.

[0010] As a further scheme of the utility model: the bottom plate is connected with the S-shaped filter brick outside through the inner side of adjusting hole of screw.

[0011] As a further scheme of the utility model: the section shape of the adjusting hole is long strip.

[0012] Compared with the prior art, the utility model has the beneficial effects of:

[0013] The utility model discloses through bottom plate and water distribution opening even distribution of water inlet to every group S type filter brick, thereby auxiliary S type filter brick even distribution of water inlet to the whole denitrification filter tank, through adjusting hole can be to the position of bottom plate and S type filter brick carry out fine adjustment, thereby make every row water distribution device installation spacing consistent, thereby make the water of whole denitrification filter tank even, convenient to remove nitrogen, increase denitrification efficiency, and convenient to install, adjust.
