Reversible grid plate of grid flocculation tank

Technical Field

The utility model relates to a drinking water treatment technology field, concretely relates to grid flocculation tank's grid board that can overturn.

Background

The flocculation tank in the drinking water treatment field mainly comprises grid flocculation and folded plate flocculation, wherein the grid flocculation tank is widely applied to various large and medium water plants in China due to the advantages of convenience in installation, simple structure and the like. The grid flocculation tank is composed of a plurality of grid shafts, a plurality of layers of grid plates are arranged in each grid shaft and are staggered up and down to form a serial channel, and the grids form a speed gradient when passing water to start flocculation. Along with the time lapse, flocculation mud will progressively subside the adhesion on grid plate surface, and the mesh progressively dwindles or even blocks up, and the via hole velocity of flow increases, and velocity gradient changes to cause the unable gathering of tiny alum blossom, big alum blossom fracture, the flocculation effect variation, and then the condition of influence treatment water quality. When taking place above-mentioned condition, just need wash the maintenance to the grid plate, at present, the net of most water works all is independent installation, is fixed in the shaft, and during manual cleaning, at first need carry out the shut down to the production line, with flocculation basin emptying, adopt high-pressure squirt or artifical entering shaft in wash, the production influence is big, and the manual operation degree of difficulty is big. According to many cases in recent years, the problem that the grid plate of the flocculation tank is difficult to clean and maintain exists in a large quantity. Because urban water supply is in the livelihood, the water plant generally can not stop production or reduce production, therefore, must develop one kind and need not to take out the grid plate and wash, be convenient for clear grid plate, ensure water plant normal operating, reduce artificial input, guarantee to go out water quality of water and stably reach standard for a long time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a grid flocculation basin's grid board that can overturn realizes that the grid board is left to mud and is washd.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a grid flocculation basin's grid board that can overturn, includes the grid body and sets up the axis of rotation and the haulage rope of setting at grid body opposite side in grid body one side, the axis of rotation setting on the shaft inner wall, the haulage rope connect and pull the subassembly.

Preferably, the rotating shaft is connected with a limiting assembly.

Further preferably, the limiting component is an L-shaped limiting block fixedly connected below the rotating shaft.

Still further preferably, the L-shaped limiting block includes a transverse arm parallel to the grid plate body and a vertical arm perpendicular to the transverse arm.

Still further preferably, when the grid plate body is in a horizontal state, the vertical arm is tightly attached to the inner wall of the vertical shaft.

Preferably, the rotating shaft is horizontally arranged in the shaft.

Preferably, a gap is reserved between one side of the grid plate body, which is connected with the traction rope, and the inner wall of the shaft.

Preferably, the inner wall of the shaft is provided with a groove body for accommodating the rotating shaft.

Preferably, the shaft is provided with a support frame for supporting the traction rope.

Preferably, the hauling cable is a steel rope.

Compared with the prior art, the utility model has the advantages of it is following:

1. the utility model discloses a rotation axis, haulage rope and traction assembly's cooperation design, can realize that the grid plate body upwards overturns around the rotation axis, in the upset process, the flocculation sludge that the deposit adhesion was on the grid plate surface is washed away through the shearing force of rivers, and mud falls into the shaft bottom, easy operation, clean effectual, need not to empty the air pond and wash the grid plate, guarantee water works normal operating, reduce artifical input, guarantee that water quality of water is stable up to standard for a long time;

2. the utility model limits the rotation angle of the grid plate body around the rotation shaft through the arrangement of the limiting component, supports the grid plate body and improves the controllability and reliability of the turnover process;

3. the utility model ensures that the grid plate body can smoothly turn around the rotating shaft to turn over through the arrangement of the clearance between the grid plate body and the inner wall of the vertical shaft;

4. the utility model discloses the shearing force of make full use of rivers realizes that the grid plate skimming washs, need not to take out the washing with the grid plate body, easy operation, labour saving and time saving.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments. The following examples are carried out on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following examples.

Example 1

A reversible grid plate of a grid flocculation tank is shown in figures 1-3 and comprises a grid plate body 1, a rotating shaft 2, a traction rope 3 and a limiting component 5, wherein the rotating shaft 2 and the grid plate body 1 are connected into a whole and fixed with the wall of a vertical shaft 4 tank, and the limiting component 5 is arranged below the rotating shaft 2.
