Description

Basket lifting grid for sewage treatment

Technical Field

The utility model relates to a sewage treatment device field specifically is a hand-basket grid for sewage treatment.

Background

The grid plays a very important role in sewage treatment and is also the first step of sewage treatment. A large amount of floating objects such as leaves, vegetable leaves, cloth strips, plastic bags and the like are often mixed in the sewage, and if the floating objects are not removed and enter the sewage treatment system, the normal operation and the treatment effect of the sewage treatment system can be seriously influenced. The urban sewage treatment plant has large treatment scale, is usually provided with a thick grating and a thin grating at the front end of a treatment system, is mostly a mechanical grating, can automatically operate and effectively remove impurities. However, small-scale village and town sewage treatment stations are often limited by investment amount, and only a thick artificial grid is arranged at the front end of the station.

Example 1

As shown in fig. 1, a basket grid for sewage treatment comprises a fixed cavity part 1, a water inlet pipe 2 and a filter assembly 3; the bottom of the fixed cavity part 1 is communicated with a water inlet pipe 2, the filter component 3 is detachably arranged in the fixed cavity, and the size of the filter component 3 is not larger than that of the fixed cavity; each filtering face of the filtering assembly 3 is opposite to each face of the fixed cavity portion 1.

Based on the structure, when the filter assembly is used, liquid to be filtered passes through the filter assembly 3, impurities are retained in the filter assembly 3, when the impurities are excessive, the water pressure passing through the filter holes is increased, the filtered water flow is directly contacted with the fixed cavity part 1, partial kinetic energy is offset after the filtered water flow is contacted with the fixed cavity part 1, the water flow can be effectively prevented from being sprayed to the wall of the pool and the body of an operator, unnecessary pollution is reduced, and meanwhile, the occurrence of sanitary accidents is also reduced;

the fixed cavity part 1 is funnel-shaped, the water inlet pipe 2 is connected with the bottom position of the funnel-shaped fixed cavity part 1, at least one overflow port is arranged on the fixed cavity part 1, and the overflow port is arranged on the side wall of the fixed cavity part 1 far away from the water inlet pipe 2;

based on above-mentioned structure, along with long-time filtration, when filtering efficiency was low excessively, it can get into in the pond through overflow mouth discharge to filter liquid, prevents to appear filtering the condition of wantonly crossing current.

The filtering component 3 comprises a screen 31 and hanging lugs 32, the screen 31 is connected with each other to form a cubic structure with one open end, the hanging lugs 32 are arranged perpendicular to the open end of the cubic structure, and the length of the hanging lugs 32 protrudes out of the cubic structure; the filter component 3 is hung on the fixed cavity part 1 through the hanging lug 32, and impurities in the liquid to be filtered are filtered.

The hanging lugs 32 are arranged on the upper parts of two opposite sides of the screen 31.

In other embodiments, bottom position at filter assembly 3 is provided with support frame 33, filter assembly 3 can place on support frame 33, because in long-time filtering process, impurity in filter assembly 3 can increase gradually, lead to the weight in filter assembly 3 to increase, only rely on hangers 32 can't stabilize fixedly to it, consequently the inventor sets up support frame 33 in filter assembly 3, prevent the damage of hangers 32, and can make the manual work can propose the string bag fast through the hangers, clear up impurity, reduce the number of times of maintaining simultaneously, can promote filterable efficiency.

The support frame 33 can be one or more of angle steel, flat steel and round steel, and the support frame 33 is fixedly connected with the inside of the fixed cavity part 1.

The aperture of the screen 31 is less than or equal to 3 mm; compared with most basket grids in the market, the basket grid structure has small gaps, can effectively intercept most impurities in the incoming water, and really plays a role in making up negative effects brought by failure of the front-end grid;

the one end of inlet tube 2 with funnel bottom intercommunication, the other end stretch into the pond certain degree of depth below the surface of water, the inlet tube 2 of water funnel can stretch into the aquatic, and 2 length of inlet tube can be adjusted, then stretch into the degree of depth and can adjust thereupon, make the hydroenergy through the string bag according to the design needs, upper portion gets into biochemical pond, perhaps gets into biochemical pond from the lower part, prevents the short stream of water.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
