Abstract

The utility model discloses a garbage crusher for crushing solid pollutants floating or suspending in the sewage in water inlet ditches or pipelines of urban water supply and drainage, sewage pump stations and the like. The garbage crusher comprises a box cover, a box body, a driving shaft and a driven shaft provided with uniformly distributed multi-teeth cutters, and a pair of grid drums, wherein a driving wheel is arranged on the driving shaft, a driven wheel is arranged on the driven shaft, and the driving wheel and the driven wheel are mutually engaged; and drum gears are sleeved on the drum shafts of the drums, the drum gears are mutually engaged with the driving wheel and the driven wheel through a pair of intermediate gears respectively, a plurality of uniformly distributed cutting blades are arranged on grids of the drums, and each cutting blade is positioned between two adjacent multi-teeth cutters. The cutting blades can directly cut elongated fibers, cloth and the like to prevent the elongated fibers, the cloth and the like from winding a rotary hub of the crusher to reduce overflow quantity and prevent the elongated fibers, the cloth and the like from directly passing through the rotary hub and winding the impeller of a subsequent pump to plug the pump.

Description

Refuse grinder

Technical field

The utility model relates to a kind of disintegrating apparatus, relates in particular in irrigation channel such as urban water supply and sewerage, sewage pumping station and the pipeline floating or be suspended in solid refuse disintegrating machine in the sewage.

Background technology

Grid sewage-removing machine that is provided with on existing sewage water inlet pipe road or the channel or disintegrating machine mostly adopt disc or grizzly bar type rotary drum to cut dirt after pulverizer or disintegrating machine are pulverized blowdown, have the following disadvantages: the rotation of rotary drum can only push the solid pollutant of bulk that pulverizer or disintegrating machine are pulverized or be broken, can't pulverize for fibrous strip solid dirt floating in the sewage such as strip snakeskin cloth or strip plastic garbage bag, because above material will be attached on the rotary drum after floating to pulverizer or disintegrating machine commentaries on classics hub place with sewage, rotate not enter and pulverize the district and pulverize with changeing hub, thereby cause the water pump obstruction or be wrapped in minimizing water flow on the rotary drum always and directly enter pump intake, and maintenance is inconvenience very, has a strong impact on normal blowdown.

The utility model content

The utility model purpose is to overcome the deficiencies in the prior art, provide a kind of simple in structure, the loss of flood peak is little, high efficiency, cross effective foul drainage or the pipeline New-type refuse vehicle disintegrating machine of water, has solved the well present situation of broken fiber shape strip solid dirt of common pulverizer or disintegrating machine.

The technical solution of the utility model is achieved in that

A kind of refuse grinder, comprise casing, the driving shaft of the multiple tooth cutter of even distribution and driven shaft be installed, a pair of grizzly bar type rotary drum, described driving shaft and driven shaft are installed on the described casing, end at described driving shaft is equipped with driving wheel, end at described driven shaft is equipped with driven pulley, and described driving wheel and described driven pulley are meshing with each other; Described a pair of grizzly bar type rotary drum is installed on the described casing by the rotary drum axle, on described rotary drum axle, be set with drum gear, described drum gear is meshing with each other with described driving wheel and driven pulley respectively by a pair of carrier gear, described carrier gear is sleeved on the described gap bridge axle, and described gap bridge axle is installed on the described casing; It is characterized in that: several equally distributed cutting blades are installed on the grizzly bar of described rotary drum, and described each cutting blade is between described adjacent two multiple tooth cuttves.

Described casing is provided with case lid.

The cross section of described driving shaft and driven shaft is a regular polygon, and described multiple tooth broach shell is contained on described driving shaft and the driven shaft, is provided with multiple tooth edge bearing sheet between adjacent two multiple tooth cuttves.

The cross section of described grizzly bar is a regular polygon, and described cutting blade is sleeved on the described grizzly bar, is provided with pad between adjacent two cutting blades.

The utility model compared with prior art has following advantage:

1. after sewage had irrigation channel or pipeline to enter, the commentaries on classics hub of casing both sides had stopped floating thing, suspension effectively, and guided it to enter the cutting and crushing zone to carry out fragmentation; Change hub and be provided with the sheet-type cutting blade, can be directly with the strip fiber, clothes etc. directly cut, thereby avoided strip fiber, cloth etc. to twine disintegrating machine and changeed hub minimizing inflow-rate of water turbine, also can avoid simultaneously causing the obstruction of pump owing to strip fiber, cloth etc. directly twine the impeller of subsequent pump by changeing hub.

2. the cross section of driving shaft, driven shaft and grizzly bar is a regular polygon, and the installation of convenient so multiple tooth cutter and cutting blade need not to adopt other auxiliary fixing device, and is convenient for installation and maintenance.

3. casing is provided with case lid, and each transmission device such as assurance gears engaged is worked under clean environment, has prolonged the service life of transmission device.
