Description

Internal inflow superfine grid dirt remover difficult to block

Technical Field

The invention belongs to the field of sewage treatment, and particularly relates to an inner inflow ultra-fine grid sewage remover which is not easy to block.

Background

The inner inflow superfine grille decontamination machine mainly comprises a driving device, a frame, a traction chain, a screen plate, a flushing system, an electric control system and other main components. The driving motor is arranged on a main shaft in the forward direction of the frame, the two side screen plates are driven by the driving chain to upwards extract dirt trapped in the length range of the motor from bottom to top, when the motor reaches the upper part, the dirt discharging work is automatically completed under the action of flushing water of the overhead flushing device through the steering function of the chain wheel, and the slag water is discharged out of the self-flowing machine after being discharged into the slag collecting groove between the two side screen plates. Screw-type adjusting devices are arranged on the front side and the rear side of the frame to adjust tightness of the transmission chain. The frame of the inner inflow ultra-fine grid dirt remover is an integral cuboid rigid structure formed by assembling and welding stainless steel plates and section steel. The lower part of the frame is provided with a water inlet hole at the water facing end, the front and rear wall plates of the frame are provided with guide rails, and the upper part of the frame is also provided with an internal slag collecting groove which extends to the outside of the frame. The frame is arranged in the center of the grid well, and gaps between two sides of the frame and the grid well are passages for water after grid filtration. The two sides of the water facing end of the frame are provided with the diversion baffles, which can prevent floating garbage from passing through while diversion. The traction chain wheel and the guiding device for driving are respectively arranged at the upper part and the lower part of the two sides of the frame. The grid mesh is made of stainless steel plates, and the mesh surface is provided with small holes which are regularly arranged, so that the functions of water passing and dirt interception are achieved. The equipment is provided with a screen washing system, so that most dirt trapped by the screen is effectively removed, and mesh regeneration is ensured.

The screen plate is used as a key filter medium of the equipment, the grid mesh in the existing equipment is of an L-shaped structure, when the screen plate reaches the upper part of the frame under the drive of the transmission chain, the corners of the grid mesh of the L-shaped structure are not washed to be easy to accumulate slag, so that the dirt remover is blocked in operation, the joint of the screen plate and the screen plate in the prior art is sealed by rubber, the sealing part of the screen plate is easy to tear along with the transmission process of the transmission chain, and garbage blocking is caused between the screen plates. The floating big garbage enters the inner inflow ultra-fine grid and is easy to be blocked in the net plate and is not easy to come out.

Disclosure of Invention

The invention aims to: the invention aims to provide an inner inflow ultra-fine grid dirt remover which is not easy to block aiming at the defects of the prior art.

The invention has the innovation points that the L-shaped grid net structure is changed into a plane structure, and slag is not easy to accumulate during flushing; the joint of otter board and otter board adopts canvas to seal, is difficult for breaking, is difficult for the long-pending sediment, sets up the strengthening rib in the otter board and sets up the blade in strengthening rib department, can prevent effectively that rubbish card from causing the condition that the sewage filter was low in the otter board.

The technical scheme is as follows: in order to achieve the above object, the present invention is specifically realized as follows: the utility model provides an interior inflow superfine grille dirt separator that difficult card hinders, includes a plurality of otter boards, drive chain, and the otter board is formed by plate frame and grid net welding, the plate frame is cuboid structure and inside has the cavity, has rectangular through-hole on the face that the plate frame comprises long limit and broadside, and one of them through-hole welds has the rectangle grid net that covers the through-hole, and another through-hole is equipped with connecting hole, broadside department in the surrounding long limit department and is equipped with the hinge hole, otter board parallel arrangement just is connected through hinge hole and drive chain. The grid net is covered in a plate frame with a rectangular structure and a cavity inside, when the net plate reaches the upper part of the frame under the drive of the transmission chain, the net plate can be washed more thoroughly under the washing action of the washing device, and the blockage of the inner inflow superfine grid dirt remover can not be caused.

Further, the inside face that the long limit of board frame and high limit are constituteed is filled with polymer plastic filler, and polymer plastic filler covers the connecting hole, and otter board junction adopt rectangular canvas to seal, pass the connecting hole through self tapping screw between canvas and the otter board and fix. The net plate and the net plate are not easy to tear after being sealed by canvas, so that the blockage of the inner inflow superfine grid dirt remover is avoided; the canvas and the screen plate are fixed by penetrating through the connecting holes through self-tapping screws, so that the canvas and the screen plate are convenient, quick and time-saving.

Further, the plate frame is formed at one time, and is easy to process, convenient to install and high in firmness.

Further, a plurality of reinforcing ribs are welded in the plate frame, and the plate frame is not easy to bend.

Further, be equipped with a plurality of blades on the strengthening rib, have the play water of the interior inflow superfine grille dirt separator of influence behind plastic film etc. big rubbish card in the otter board to strain, the otter board shakes under drive chain's transmission effect and drives the blade and cut the rubbish in the otter board behind the blade on the strengthening rib, then washes under washing unit's washing effect.

The invention has the beneficial effects that: compared with the prior art, the invention has the following advantages:

1. in the invention, the rectangular grid net is covered in the plate frame with the rectangular structure with the cavity inside, and when the net plate reaches the upper part of the frame under the drive of the transmission chain, the net plate can be washed more thoroughly under the washing action of the washing device, so that the blockage of the inner inflow superfine grid dirt remover can not be caused.
