Abstract

The utility model relates to a self-cleaning grate cleaner. The self-cleaning grate cleaner comprises a motor reducer, plow-shaped harrow teeth, a cleaning brush, a tension sprocket, a haulage chain and the like, wherein the plow-shaped harrow teeth are overlapped and connected in series with each other to form an annular grate curtain covering the overall upstream face; the distance between adjacent two shafts which are connected in series is 100 mm; the motor reducer drives a main drive sprocket, a large sprocket and a transmission main shaft to drive the haulage chain to pull the overall annular grate curtain to rotate at the uniform speed (2.2 m/min); the lower part of the annular grate curtain is immersed in a water flowing ditch; sundries in water is carried by a grate surface to move upward along a railway, so that the sundries are brought out of a water surface; when the sundries are traveled to the top of a grate, because of the guide effect of the guide rails and the sprockets, adjacent plow-shaped harrow teeth are pushed against with each other in a staggered way, so that the sundries attached to the grate surface are pushed out; the sundries fall into a dirt container by the self gravity; the other part of sundries with high viscosity is cleaned under the rotating and brushing effects of the cleaning brush when the sundries are rotated back to the lower part of the sprockets.

Description

A kind of self-cleaning type grid sewage-removing machine

Technical field

The utility model relates to a kind of dirt remover, particularly relates to a kind ofly having from decontamination function, and the efficient of removing contamination height has alleviated the self-cleaning type grid sewage-removing machine of labor strength.

Background technology

Large-scale intake structure water-in, sewage and rainwater promote the waste-blocking position of pumping plant, sewage work etc. all should establish the dirty equipment that blocks; Remove thick swimmer such as vegetation, rubbish and fibrous matter etc.; To reach the purpose of the processing load of protecting water pump impeller and alleviating subsequent handling; In water supply engineering, also will block the series connection of dirty equipment and filter screen sometimes uses; The former removes bigger impurity, and the latter removes less impurity, and it is necessary therefore using and blocking that dirty equipment removes contamination, reduces labor intensity and improve working conditions media implementation.

At present generally be the swimmer that adopts in the simple and easy grid interception medium, Fig. 1 is the front view of prior art structural representation, and Fig. 2 is the left view of prior art structural representation.

As illustrated in fig. 1 and 2, this wiper mechanism comprises: supporting steel 2, and grizzly bar 3 is crossed with horizontal support muscle 4 on the supporting steel 2, and grizzly bar 3 one ends are fixed on the square tube 1, and the other end is fixed on the base plate 5, and the middle portion of grizzly bar 3 is fixed on the horizontal support muscle 4.

Though above-mentioned wiper mechanism is simple in structure, there is the shortcoming of the following aspects:

(1), the grizzly bar of this wiper mechanism can only tackle the swimmer in the sewage, self does not have the function of mechanical removal impurity;

(2), because not from cleaning function, so need the artificial swimmer of tackling of removing, manual working labour intensity is big, efficient is low and security incident takes place easily.

The utility model content

To the problems referred to above, the main purpose of the utility model is to provide a kind of to be had from decontamination function, and the efficient of removing contamination height has alleviated the self-cleaning type grid sewage-removing machine of labor strength.

The utility model is achieved by the following technical solutions to solve the above problems: a self-cleaning grate discharge machine, the decontamination unit including motor reducer, plow harrow teeth, clean-up brush, tensioning sprocket , transmission shaft, the main drive sprocket, large sprocket, plow harrow teeth overlap each other after the series, combined into a ring grille covering the entire positive side curtain motor reducer drives the main drive sprocket, large sprocket and transmission spindle, driven by the traction chain traction entire annular grille curtain uniform rotation, plow harrow teeth tooth harrow and plow through the drive spindle tension between the sprocket.

In the practical implementation example of the utility model, the wheelbase between the serial connection axle of said plow-shape rake teeth serial connection back is 80-120mm, is preferably 100mm.

The positive progressive effect of the utility model is: the self-cleaning type grid sewage-removing machine that the utility model provides has the following advantages:

(1), realized machinery from decontamination function, protected the later process water pump impeller and alleviated the processing load of subsequent handling.

(2), the efficient of removing contamination height, alleviated labor strength.

(3), operate steadily safety height, basic noiseless.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.

Figure 3 is a schematic of the utility model front view, Figure 4 is a schematic of the utility model left side view, as shown in Figures 3 and 4: The utility model including motor reducer 6, plow harrow teeth 7, raking brush 8, a tension sprocket wheel 9, the traction chain member, plow harrow teeth 7 usually made of plastic or stainless steel, the rake teeth overlap each other and connected in series to form a ring covering the entire upstream face grille curtain, with o two tandem axle wheelbase of 100 between the motor reducer 6 drives the main drive sprocket 11, a large sprocket 12 and the drive shaft 10, driven by the traction chain traction entire annular grille curtain uniform rotation (2.2m / min), the lower part of the ring grille curtain drains immersed in the past, the gate surface debris along the track to bring up the water, brought to the surface, when you run to the top of the grille, as the guiding role of rail and sprockets adjacent rake teeth have a mutual dislocation passes, which will rely on the gate surface dirt launch, dirt falling into the dirt receptacle by its own weight, and the other part of the relatively high viscosity of the dirt, go back to the lower sprocket, through the clean-up brush rotary brushing effect, be removed.

The utility model has been realized machinery from decontamination function, has protected the later process water pump impeller and has alleviated the processing load of subsequent handling; The efficient of removing contamination height has alleviated labor strength; Operate steadily, safety is high, basic noiseless.

More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
