Detailed Description

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

A first embodiment, as shown in fig. 1 to 4:

the supporting structure of the rotary grating machine comprises a washing mechanism fixedly arranged in front of the upstream face of the rotary grating machine 1, wherein the washing mechanism comprises a water sprayer, a water spraying port of the water sprayer faces the position, higher than the water face, of the upstream face of the grating of the rotary grating machine 1, and the spraying range of water sprayed through the water spraying port can cover the width of the upstream face.

In the technical scheme, the position where the water flow in the sewage inlet tank 2 arrives first is taken as the front, and the position where the water flow arrives later is taken as the back.

The matching structure of the rotary grating machine has the advantages that:

can wash the mud slick of adhesion on the dirty sediment that promotes on the grid of rotation grid machine 1 through the water spray of water sprayer, and then reduce the mud slick content of pouring into the dirty sediment in connecing the sediment ware, the reduction of mud slick content has also together reduced the water content (rate) and the weight of dirty sediment in connecing the sediment ware to can help reducing the dirty sediment and shift required energy consumption.

The matching structure of the rotary grating machine has the advantages of simple structure and easy implementation, is suitable for being arranged and installed beside the existing rotary grating machine 1, has lower running and using cost, and can improve the benefit.

The water sprayer comprises a jet flushing pipe 3, the length direction of the jet flushing pipe 3 is consistent with the width direction of the grating of the rotary grating machine 1, a plurality of jet holes are arranged at intervals along the length direction of the jet flushing pipe 3, and the plurality of jet holes form the water spray opening.

The jet flushing pipe 3 is simple in structure, and is easy to fixedly erect and install in front of the upstream face of the rotary type grating machine 1 through a support, so that the installation efficiency is improved.

The jet flushing pipe 3 is connected with an output port of a water pump through a water conveying pipe, and an input port of the water pump is connected with a water source filled with reclaimed water through a pipeline.

In the art, tap water flowing into a household is referred to as "upper water", discharged sewage is referred to as "lower water", and reclaimed water subjected to sewage purification treatment is referred to as "reclaimed water".

A 'water source (pool) filled with reclaimed water' in a sewage treatment plant is provided with a 'sedimentation tank' or a 'water outlet tank' of the sewage treatment plant.

Adopt the normal water to wash, not only can reduce the water cost like this, can also utilize "normal water" to the grating to face the water wash and promote the cleanliness of grating, effectively avoid causing the situation that the dirty sediment does not fall because of the grating is dirty, the slagging-off performance of better assurance grating.

Wherein, the jet flushing pipe 3 crosses the sewage inlet tank 2, and two ends of the jet flushing pipe 3 are fixedly arranged on the top surfaces of two tank walls of the sewage inlet tank 2.

Thus, the bracket can be omitted or the height of the bracket can be reduced, the cost for laying the jet washing pipe 3 can be reduced, and the convenience and safety of laying can be improved.

Wherein, a scattering spray head 31 is hermetically arranged at each spray hole.

The scattering spray head 31 has the advantage of large spray coverage; the device also has moderate injection force, can effectively wash away the floating mud on the dirty slag, and can not wash off the dirty slag from the rake teeth of the rotary type grating machine 1, thereby reliably ensuring the cleaning effect of the dirty slag.

Wherein the water pressure in the jet-flushing pipe 3 is 0.1 to 0.2 mpa.

By adopting the water pressure, the better floating mud flushing effect is obtained, and simultaneously, the dirt slag is not easy to fall off from the rake teeth of the rotary type grating machine 1, so that the water pressure type floating mud flushing device has better use effect.

The supporting structure of the rotary type grating machine further comprises a mud block crushing mechanism fixedly arranged in front of the upstream surface of the rotary type grating machine 1, the mud block crushing mechanism comprises a retaining column 5, the retaining column 5 is vertically and fixedly arranged on the wall of the sewage inlet groove 2, the lower section of the retaining column 5 is positioned below the water surface of the sewage inlet groove 2, and the thickness of the retaining column 5 in the direction perpendicular to the wall of the sewage inlet groove 2 is 10-30 cm.

During implementation, the blocking column 5 is fixed on the wall of the sewage inlet groove 2 through screws.

Adopt above-mentioned mud piece crushing mechanism, can be used for changing the flow direction of 2 avris sewage of sewage intake chamber through the striking with bumping post 5 for avris sewage can be close to and flow in along the flow direction of 2 width direction middle part sewage of perpendicular to sewage intake chamber, forms the impact effect, thereby can break away the mud floating of the great area of blocking, and then better guarantees final mud floating and washes the effect.

Wherein, be provided with two at least on two inside walls of sewage intake chamber 2 fender post 5.

Therefore, the impact effect of sewage on the floating mud on the water surface from the side of the sewage inlet tank 2 can be enhanced, and the floating mud with large block area can be better guaranteed to be dispersed.

Wherein, the bumping posts 5 arranged on the two inner side walls of the sewage inlet tank 2 are staggered in the length direction of the tank body.

The setting of above-mentioned bumping post 5 can form great face of passing through, is difficult for forming longer dirty sediment (like branch, bar etc.) in the sewage intake chamber 2 and blocks to effectively ensure the final effect of being cleared up of various dirty sediment.

Wherein, the upstream surface of bumping post 5 is the arc profile.

When the arc-shaped surface is implemented, the arc included angle corresponding to the arc-shaped surface is preferably smaller than 90 degrees.

Therefore, the upstream face of above-mentioned bumping post 5 has more excellent direction diversion effect, can make 2 avris sewage of diversion have bigger kinetic energy, promotes the power of rushing away and the effect of rushing away to the surface of water mud of floating.

The second embodiment, as shown in fig. 5:

the present embodiment is different from the first embodiment in that: the flushing mechanism further comprises a water surface injection pipe 4, the water surface injection pipe 4 stretches across the sewage inlet tank 2, and two ends of the water surface injection pipe 4 are fixedly arranged on the top surfaces of two tank walls of the sewage inlet tank 2; the water surface injection pipe 4 is provided with a plurality of injection holes which are vertically downward and are injected to the water surface of the sewage inlet tank 2, and the plurality of injection holes are arranged along the length direction of the water surface injection pipe 4 at intervals. The water surface jet pipe 4 is communicated with a reclaimed water source through a water pump.

Like this, adopt above-mentioned surface of water injection pipe 4 after, can strike the surface of water of sewage intake gutter 2 for the better dispersion of mud slick is opened, reduces final adhesion and floats mud cover area and adhesion in the grid upper end, more does benefit to the effectual spary of sprinkling machine and washes away the mud slick on the grid, promotes mud slick and gets rid of the effect.

The above is only the preferred embodiment, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the technical scope of the present invention, and the technical scope of the present invention is also considered to fall into the scope of the claims.
