Abstract

The utility model discloses a kind of anti-blocking hydraulic screens, including sieve seat, sieve is installed on the sieve seat, at least one shaft is rotatably equipped on the sieve seat at the sieve rear, at least one eccentric wheel is fixedly installed in the shaft, the distance between the shaft and the sieve are greater than the minimum outer diameter of the eccentric wheel and are less than the maximum outside diameter of the eccentric wheel, are equipped with the driving motor that power output end is connect with the rotating shaft transmission on the sieve seat；Shaft rotation is driven by driving motor, shaft band movable eccentric wheel rotates, when the biggish position of eccentric wheel outer diameter is close to sieve, eccentric wheel strikes sieve, to the solids precipitated on sieve be struck, during filter sewage, automatic cleaning sieve, prevents sieve from blocking.

Description

Anti-blocking hydraulic screen

Technical field

The utility model sewage purification treatment equipment technical field, more particularly to it is a kind of for solid impurity in filter sewage Hydraulic screen.

Background technique

Hydraulic screen main body is wedge-shaped rod iron through stainless steel arc made of precision or flat filter compass screen surface, waste water to be processed It is evenly distributed on inclination compass screen surface by overflow weir, solid matter is trapped, and filtered water is flowed out from sieve gap, simultaneously Under hydraulic action, solid matter is pulled to the discharge of sieve plate lower end, to reach separation of solid and liquid purpose.Hydraulic screen for sludge or Channel cleanout pretreatment can effectively clear up waste, dredge water route, realize the regulation in river, while can be used for agriculture filling It irrigates with water process etc., is widely used in hydraulic engineering.

Hydraulic screen in the prior art there is a problem of be easy be blocked, can still be deposited on table using rear waste for a long time Face, cleaning is inconvenient, while significantly reducing the solid-liquid separation effect of hydraulic screen.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of by shaking sieve to prevent sieve from blocking Anti-blocking hydraulic screen.

In order to solve the above technical problems, the technical solution of the utility model is: anti-blocking hydraulic screen, including sieve seat, institute It states and sieve is installed on sieve seat, be rotatably equipped at least one shaft on the sieve seat at the sieve rear, described turn At least one eccentric wheel is fixedly installed on axis, the distance between the shaft and the sieve are greater than the minimum of the eccentric wheel Outer diameter and the maximum outside diameter for being less than the eccentric wheel, are equipped with power output end on the sieve seat and connect with the rotating shaft transmission Driving motor.

As a kind of perferred technical scheme, the sieve seat includes supporting frame, is equipped with and inclines on support frame as described above body The screen frame being tiltedly arranged, the sieve are fixedly mounted in the screen frame.

As a kind of perferred technical scheme, the screen frame includes two side guard plates, a top backplate and a bottom shield Plate is welded with sieve erecting bed on the inner wall of the side guard plate, and the sieve is mounted by means of bolts on the sieve and fixes On platform.

As a kind of perferred technical scheme, support frame as described above body includes triangle frame body, the bottom end weldering of the triangle frame body It is connected to support leg.

As a kind of perferred technical scheme, the driving motor is waterproof machine.

By adopting the above-described technical solution, anti-blocking hydraulic screen, including sieve seat, sieve is installed on the sieve seat Net is rotatably equipped at least one shaft on the sieve seat at the sieve rear, is fixedly installed at least in the shaft One eccentric wheel, the distance between the shaft and the sieve are greater than the minimum outer diameter of the eccentric wheel and are less than the bias The maximum outside diameter of wheel is equipped with the driving motor that power output end is connect with the rotating shaft transmission on the sieve seat；Pass through drive Dynamic motor drives shaft rotation, and shaft band movable eccentric wheel rotates, when the biggish position of eccentric wheel outer diameter is close to sieve, eccentric wheel It strikes sieve and during filter sewage, clears up sieve automatically to striking the solids precipitated on sieve, prevent Only sieve blocks.

Specific embodiment

Below with reference to embodiment, the utility model is further described.In the following detailed description, only pass through the side of explanation Formula describes certain exemplary embodiments of the utility model.Undoubtedly, those skilled in the art will recognize, Without departing from the spirit and scope of the utility model, can with a variety of different modes to described embodiment into Row amendment.Therefore, description is regarded as illustrative in nature, and is not intended to limit the scope of the claims.

As depicted in figs. 1 and 2, anti-blocking hydraulic screen, including sieve seat are equipped with sieve 1, the sieve on the sieve seat It is rotatably equipped at least one shaft 21 on the sieve seat at 1 rear of net, is fixedly installed at least one in the shaft 21 Eccentric wheel 22, the distance between the shaft 21 and the sieve 1 are greater than the minimum outer diameter of the eccentric wheel 22 and are less than described The maximum outside diameter of eccentric wheel 22 is equipped with the driving motor of power output end and the shaft 21 transmission connection on the sieve seat (not shown).The driving motor is waterproof machine.

The sieve seat includes supporting frame 3, and the screen frame being obliquely installed, the sieve are equipped on support frame as described above body 3 Net 1 is fixedly mounted in the screen frame.The screen frame includes two side guard plates, 41, top backplates 43 and a bottom backplate 44, as shown in figure 3, being welded with 1 erecting bed of sieve on the inner wall of the side guard plate 41, the sieve 1 is bolted installation On 1 fixed station of sieve.Support frame as described above body 3 includes triangle frame body, and the bottom end of the triangle frame body is welded with support leg.

When work, shaft 21 is driven to rotate by driving motor, shaft 21 is rotated with movable eccentric wheel 22, when outside eccentric wheel 22 When the biggish position of diameter is close to sieve 1, eccentric wheel 22 strikes sieve 1, so that the solids precipitated on sieve 1 is struck, It is automatic to clear up sieve 1 during filter sewage, prevent sieve 1 from blocking.It can be set according to the content of solids in sewage The working frequency of driving motor.

Can be according to the specification of sieve 1, the appropriate quantity for increasing and decreasing shaft 21 and eccentric wheel 22, if 1 area of sieve compares Greatly, two or more shafts 21 can be set, one or more bias can also be installed in a shaft 21 Wheel 22.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
