Description

Filter screen plate with hexagonal honeycomb-shaped meshes

Technical Field

The utility model relates to a sewage treatment device accessory field, in particular to filter screen plate of hexagonal honeycomb shape mesh.

Background

An internal inflow type screen plate grid sewage removing machine is a high-efficiency fine grid sewage removing device which integrates sewage blocking and sewage removing. The device is suitable for being used as a fine grid for large, medium and small pump stations, and is used for intercepting and removing floaters in water, such as: weeds, paper pieces, cigarette ends, melon seeds, fibers, hairs and the like, and the machine type has high dirt capture rate and can effectively implement the subsequent treatment process. The internal inflow type screen plate grid cleaner mainly comprises a driving device, a frame, a traction chain, a filter screen plate, a flushing system, an electric control system and other main components. The driving motor is arranged on a forward main shaft of the frame, the filter screen plates on the two sides are driven by the transmission chain to upwards extract the dirt intercepted in the length range from bottom to top and reach the upper part, and most of solid matters fall to the slag groove by gravity to be discharged.

In order to extract more dirt as much as possible when the filter screen plate moves upwards, rake teeth on the filter screen plate are generally designed to be upwards inclined, but the design brings about the problem that when the filter screen plate moves to the topmost end, the dirt falls smoothly by gravity, even part of the dirt cannot fall smoothly, or cannot fall smoothly to a slag groove but falls back into the sewage, even the dirt continues to return to the sewage along with the rake teeth, so that the working efficiency is greatly influenced, and the improvement is urgently needed.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a filter screen plate with hexagonal honeycombed meshes.

In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:

Because the gravity of filth is downward all the time, the otter board rises the in-process, rake teeth mechanism mainly is rake teeth platform pressurized, cut dirty rake teeth part pressurized, under the effect of elastic component, cut dirty rake teeth can remain stable difficult upset, thereby can take the filth to the top smoothly, when the otter board rises to the top, the gravity of filth is born by cutting dirty rake teeth gradually, it begins to overturn downwards to cut dirty rake teeth, make the filth drop to the sediment inslot smoothly, simultaneously under the effect of dog, can prevent to cut dirty rake teeth upset excessively, fall behind when the filth, it returns to the normal position to cut dirty rake teeth under the elastic component effect.

The utility model discloses a further improvement lies in, the elastic component includes that spring and cover locate the outer rubber hose of spring, rubber hose's outer wall is the fold form, and the both ends of spring and rubber hose are fixed in respectively on the otter board and cut dirty rake teeth.

The utility model discloses a further improvement lies in, otter board, rake teeth mechanism and dog are the polyethylene injection molding, otter board, rake teeth platform and dog structure as an organic whole adopt the ultra high molecular polyethylene as the system material, and the surface is smooth and have sufficient intensity and rigidity, is difficult for producing the absorption of hair flocculus.

The utility model discloses a further improvement lies in, two faces of otter board are close to the edge and all are equipped with the strengthening rib strip, improve otter board intensity.

The utility model is further improved in that the included angle between the screen plate and the sewage intercepting rake teeth is an acute angle, and the included angle range is 45-60 degrees.

The utility model has the advantages that:

(1) the utility model discloses a cut dirty rake teeth through articulated design, cooperation elastic component, cuts dirty rake teeth and is the tilt up form, can hold back more filths as far as possible at the ascending in-process of otter board, rises to the top at the otter board simultaneously, cuts dirty rake teeth under the too big condition of atress, and upset downwards makes the filth drop to the cinder notch smoothly, has improved work efficiency greatly.

(2) The utility model discloses a design of honeycomb mesh and polyethylene injection structure, the difficult winding, jam and the floccule adsorption phenomena that form in otter board surface, debris are difficult for adhering to.
