Novel filtering brick

Abstract

The invention discloses a novel filtering brick, which comprises a main filtering brick body (1), wherein the inner part of the main filtering brick body (1) is provided with an inner cavity (2), and the inner cavity (2) penetrates through the whole main filtering brick body (1) from left to right; the top of the main filtering brick body (1) is provided with a fixing device, and the front side and the rear side of the main filtering brick body (1) are respectively provided with a plurality of brick legs (3); a gap (4) is arranged between every two brick legs (3); and the outer surface of each brick leg (3) is provided with a filtering brick limiting block (5). The novel filtering brick has a better fluid characteristic and higher strength, the uniformity achieves more than 95 percent, and the novel filtering brick is more economic and is easier and firmer to install.

Description

technical field [0001] The invention relates to a novel filter brick. Background technique [0002] At present, the water distribution and gas distribution systems used in the filtration process of filter bricks include: filter head filter plate, large resistance water distribution, ceramic filter brick, HDPE filter brick and T-shaped filter brick, etc. 1. As a water distribution and gas distribution system, the filter head and filter plate must be used in conjunction with the H-type recoil channel. This structure not only occupies a large area, but the length-to-width ratio of the filter is 2-3:1, and the filter area will be increased when the filter is modified. Reduction, not applicable to sewage treatment filter process. 2. Large-resistance water distribution and ceramic filter bricks are usually suitable for tap water industry, without air recoil function. 3. HDPE filter brick is a better water distribution and gas distribution system. Both tap water and sewage can be...

AI Technical Summary

Problems solved by technology

1. As a water distribution and gas distribution system, the filter head and filter plate must be used in conjunction with the H-type recoil channel. This structure not only occupies a large area, but the length-to-width ratio of the filter is 2-3:1, and the filter area will be increased when the filter is modified. Reduced, not suitable for sewage treatment filter process

2. Large resistance water distribution and ceramic filter bricks are usually suitable for tap water industry, without air recoil function

3. HDPE filter brick is a better water distribution and gas distribution system. Both tap water and sewage can be used, but the cost is expensive and the cost is high.

4. T-shaped filter bricks are equipped with a rectangular distribution main pipe on one side of the pool wall, and gas distribution branch pipes are distributed under the filter bricks. This arrangement affects the effective water distribution and gas distribution area of ​​the filter tank. The pipeline is complex and difficult to install.

In addition, there are concrete filter bricks. The recoil air of this kind of filter bricks is released through the round holes of the filter bricks, which is subjected to hydraulic resistance and has poor uniformity.
