The utility model adopts the technical proposal that: the grating process comprises a water inlet flow passage, a grating and a water drainage flow passage, wherein the grating adopts a two-section structure, sewage inlet water is physically intercepted in a first section through a small-gap grid, and dirt with the size smaller than the gap of the grid enters the other side of the grid along with the sewage after passing through the grid, is collected and is drained through the water drainage flow passage; the solid dirt with the size larger than the grid clearance enters the grid slag collecting device of the second section, and grid slag in the grid slag collecting device of the second section is periodically discharged through a slag discharge channel.

Sewage flows into first section in, and first section adopts the booth net to carry out physics to hold back, and the filth that the size is less than the grid clearance passes the opposite side that the net got into the net along with sewage, discharges away through drainage channel. As the total amount of the sewage entering the grid increases, the accumulated dirt on the grid can be increased gradually. The graticule mesh that plays the physics effect of holding back still has certain velocity of flow in the direction of intaking because the jam excessive water yield of filth can reduce, leads to the sewage that gets into, has remaining kinetic energy, and the filth on graticule mesh surface is washed the low reaches of the direction of intaking, gets into the bars sediment collection device of second section gradually. Therefore, separation and collection are separated, the interception and separation stage of the first section has a certain self-cleaning function, long-time work can be well maintained without cleaning when the size is small, and only the dirt in the grid slag collection device of the second section needs to be periodically discharged.

In the application of the grating of the buried equipment, a lifting basket can be arranged in the grating slag collecting device of the second section and used for lifting the lifting basket regularly to remove garbage in the lifting basket. The solid-liquid separation and collection processes of the grid are respectively carried out, so that the grid is different from the existing basket grid in characteristics. The utility model discloses have the operation cycle long, the operation is stable, moreover because the filth in the hand-basket is dry rubbish basically, handles simple, sanitary condition good.

Furthermore, if the grid is of a stainless steel grid type filter screen structure, and the direction of the grid on the upstream surface is consistent with the direction of the inflow water, the integral resistance of the grid is small, and the grid is not easy to block.

The invention has the advantages of simple structure, low cost, long running period, stable running and good sanitary condition.

The present invention will be described in further detail with reference to the accompanying drawings.

Detailed Description

For the purpose of promoting an understanding of the invention, reference will now be made in detail to the embodiments illustrated in the drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope thereof is not limited thereby.

As shown in fig. 1, the grid process comprises a water inlet flow passage (1), a grid and a water discharge flow passage (2), wherein the grid adopts a two-section structure, sewage inlet water is physically intercepted in a first section through a grid (11) with a small gap, and dirt with the size smaller than the gap of the grid enters the other side of the grid along with the sewage passing through the grid and is discharged through the water discharge flow passage (2); the solid dirt with the size larger than the grid clearance enters the grid slag collecting device (19) of the second section, and the grid slag in the grid slag collecting device of the second section is periodically discharged through the slag discharging channel (3). In the figure 1, the grid slag collecting device consists of a slag groove bottom (12), a slag groove side surface (16) and the like, the bottom of the slag discharging channel (3) is horizontal to the slag groove bottom, so that the slag discharging channel is convenient to pull out by a tool, the slag discharging channel can also be made into an inclined channel to discharge slag by gravity, and only one form of horizontal slag discharging is illustrated in the figure. In fig. 2, the grid slag collecting device comprises a slag groove bottom (12), a slag groove side surface (16), a basket lifting grid (17) and the like, wherein a lifting device (18) is arranged on the basket lifting grid and used for lifting the basket lifting grid out of a slag discharging channel (3) so as to discharge solid dirt intercepted by the grid, and the slag discharging channel (3) is vertically upward in fig. 2.
