In the sewage treatment, the solid pollutants are firstly removed by a pretreatment means so as to lighten the load of a post-stage process main body and ensure the safe and stable operation of the post-stage process. Generally, a grid is provided to intercept solid contaminants in sewage.
At present, the common gratings for domestic sewage treatment can be mainly divided into claw type, orifice plate (or screen plate) type, inclined drum type, horizontal drum type, crushing type and other forms. The traditional grating usually occupies a large area, and has high energy consumption, high manufacturing cost, complex structure and high maintenance cost.

The device has small volume, no energy consumption, low manufacturing cost, simple structure and low maintenance cost.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a manual grating for sewage treatment comprises a grating well, a first grating plate, a second grating plate, a third grating plate, a first sliding rail, a second sliding rail, a third sliding rail, a water inlet, a water outlet and a cover plate; an opening is formed above the grating well, and a cover plate is arranged above the opening; the water inlet is positioned at the upper part of the front end of the grating well, and the water outlet is positioned at the middle lower part of the rear end of the grating well; the first sliding rail, the second sliding rail and the third sliding rail are vertically arranged on the side wall of the grating well from front to back in parallel, and the first grating plate, the second grating plate and the third grating plate are correspondingly arranged in the first sliding rail, the second sliding rail and the third sliding rail. The first grating plate is a grid net with thicker grid gaps, and the second grating plate and the third grating plate are grid nets with thinner grid gaps with the same specification. The lower end of the grating plate is provided with a grating bottom plate which extends forwards, a bottom plate framework is arranged outside the grating bottom plate, and a bottom plate grating net which is fixed on the framework and has the same specification with the grating plate.
When solid pollutants in sewage are filtered, the sewage enters the grating well through the water inlet, larger solid pollutants are intercepted through the first grating plate, and then smaller solid pollutants are intercepted through the second grating plate and the third grating plate. When the grid mesh has a large accumulation of solid contaminants, the friction provided by the grid mesh is insufficient to support the solid contaminants to adhere to the grid mesh, and some of the solid contaminants fall down to the bottom of the grid and do not fall to the bottom of the grid.
When the grid plates are observed to intercept more solid pollutants or the cleaning period expires, an operator opens the cover plate, takes out the first grid plate, intercepts the larger solid pollutants and the smaller solid pollutants in the sewage by the second grid plate, cleans the solid pollutants on the first grid plate, and puts the first grid plate back into the first slide rail after cleaning; then taking out the second grating plate, wherein the larger solid pollutants in the sewage are intercepted by the first grating plate, the smaller solid pollutants are intercepted by the third grating plate, the solid pollutants on the second grating plate are cleaned, and the second grating plate is put back into the second sliding rail after being cleaned; and finally, taking out the third grating plate, wherein the larger solid pollutants in the sewage are intercepted by the first grating plate, the smaller solid pollutants are intercepted by the second grating plate, the solid pollutants on the third grating plate are cleaned, and the third grating plate is put back into the third slide rail after being cleaned. The solid pollutants are cleaned in a mode that the grid plates are taken out one by one from front to back, so that the solid pollutants in the sewage can be prevented from entering the back-end process to the maximum extent.
The handle is fixed on the grating plate frame, so that the operation is convenient.
Therefore, the utility model provides a floor area that traditional grid exists big, the energy consumption is high, and the cost is high, and the structure is complicated, and the high scheduling problem of maintenance cost has reached equipment small, does not consume the energy, low in cost, simple structure, the low purpose of maintenance cost.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a manual grid for sewage treatment comprises a grid well 1, a first grid plate 2, a second grid plate 3, a third grid plate 4, a first slide rail 5, a second slide rail 6, a third slide rail 7, a water inlet 8, a water outlet 9 and a cover plate 10, wherein the grid plate comprises a grid plate frame 11, a grid plate grid mesh 12, a grid bottom plate 13, a bottom plate frame 14, a bottom plate grid mesh 15 and a handle 16. An opening is formed above the grating well 1, and a cover plate 10 is arranged above the opening; the water inlet 8 is positioned at the upper part of the front end of the grating well 1, and the water outlet 9 is positioned at the middle lower part of the rear end of the grating well 1. The first sliding rail 5, the second sliding rail 6 and the third sliding rail 7 are vertically arranged on the side wall of the grating well 1 from front to back in parallel, and the first grating plate 2, the second grating plate 3 and the third grating plate 4 are correspondingly arranged in the first sliding rail 5, the second sliding rail 6 and the third sliding rail 7. The grating plate main body consists of a grating plate frame 11, a grating plate grid 12 and a grating bottom plate 13 fixed at the lower end of the grating plate frame 11 and extending forwards, the outside of the grating bottom plate 13 is provided with a bottom plate frame 14, the inside of the grating bottom plate is provided with a bottom plate grid 15, and handles 16 are arranged at two ends of the upper surface of the grating plate frame 11 for operation. The grating bottom plate 13 is tightly attached to the bottom surface of the grating well 1, the grating meshes 12 of the grating plates used by the first grating plate 2 are thick grating gaps, the grating meshes 12 of the grating plates used by the second grating plate 3 and the third grating plate 4 are thin grating gaps with the same specification, and the bottom plate meshes 15 of each grating plate are the same as the grating meshes 12 of the grating plates of the belonging grating plates in specification.
When solid pollutants in sewage are filtered, the sewage firstly enters the grating well 1 through the water inlet 8, larger solid pollutants are intercepted through the first grating plate 2, and then smaller solid pollutants are intercepted through the second grating plate 3 and the third grating plate 4. After being filtered by the grating plates, the sewage is discharged out of the grating well 1 through the water outlet 9 and enters the next process section of sewage treatment.
