Abstract
The utility model provides a novel cutting device of a sewage pump, belongs to the technical field of water pumps, and solves the problems that when a cutter in an existing sewage pump is stuck, motor overload is caused, large particles can not be smashed, and the sewage pump needs to stop for cleaning the large particles. According to the novel cutting device of the sewage pump, a water inlet and a water outlet are arranged in a pump body, a cutter in a cavity of the pump body is mounted on a rotating shaft of a drive motor, a cutting disk is fixed below the cutter, the water inlet in the pump body is located below the cutting disk, and the cutting disk is in clearance fit with the cutter. The novel cutting device of the sewage pump has the advantages of being good in smashing effect, simple in structure, long in service life and the like.
Description
Technical field
The utility model belongs to the pump technology field, refers in particular to a kind of cutter sweep of Novel sewage pump.
Background technology
Usually when Treating Municipal Sewage, to adopt sewage pump to carry, because often contain the medium of the solid particles such as fiber, paper scrap in the municipal sewage, the fibre object of this easy winding or pack causes the obstruction of pump runner easily, the in a single day blocked meeting of pump makes the pump cisco unity malfunction, even motor damage, thereby cause blowdown not smooth, bring for urban life and environmental protection and seriously influence, therefore, the anti-blocking of sewage pump and reliability are the key factors in the sewage disposal.
At present; exist on the market several sewage pumps with cutting function; its cutter sweep is to be the cutter by the driven by motor rotation substantially; thereby these cutter and have the cutterhead of inlet opening to cooperatively interact and pulverizes impurity; but this structure comes with some shortcomings: the one, though impurity is difficult for entering in the pump runner; but some fibre object of easily twining cause easily produce between cutter and the cutterhead stuck; if cutter then can cause the damages such as motor overload because of stuck; the 2nd, perforation is set as the inlet opening on the cutterhead of this structure; therefore easily occur that the larger particles foreign material directly stop up the inlet opening and cutter can't be with the situation of its pulverizing; cause the performance of work to reduce; need to shut down cleaning, operating efficiency can not be guaranteed.
Summary of the invention
The purpose of this utility model has provided the cutter sweep of good crushing effect, working stability reliable Novel sewage pump.
The purpose of this utility model is achieved in that the cutter sweep of Novel sewage pump, be provided with water inlet and delivery port on the pump housing, the cutter of pump housing inner chamber are installed in the drive motors rotating shaft, the downside of cutter is fixed with chopping disk, water inlet on the pump housing is positioned at the downside of chopping disk, it is characterized in that: described chopping disk and cutter matched in clearance, described cutter are: the periphery at the cutting tool rest that is connected mutually with machine shaft is evenly equipped with plural blade, the blade of blade is arranged on the baseplane of blade the same side, circumferentially be evenly equipped with the inlet opening on the chopping disk of blade rotary area, the inlet opening of blade baseplane one side is provided with cutting edge, the blade of described blade and cutting edge matched in clearance.
The utility model circumferentially is evenly distributed with the inlet opening on chopping disk, blade and the mutual matched in clearance of the cutting edge on the inlet opening by blade, rotating blade is pulverized foreign material in the water that pumps into, through there not being the solid impurity of larger volume in the sewage after pulverizing, so good crushing effect is simple in structure and working stability is reliable.
At the cutter sweep of above-mentioned Novel sewage pump, described blade is radioactive at the cutting tool rest and is provided with three.
Cutter sweep at above-mentioned Novel sewage pump, be provided with the centre bore of the bottom insertion of cutting tool rest on the described chopping disk, circumferentially be evenly equipped with on the chopping disk from the outward extending arc guiding gutter of centre bore, axially be provided with the straight trough that is communicated with the arc guiding gutter on the inwall of centre bore, axially be provided with circumferentially uniform groove on the face of cylinder of the cutting tool rest between adjacent two blades.
The utility model compared to existing technology outstanding and useful technique effect is:
1, of the present utility modelly in the sewage pump course of work, can will be drawn near the sewage pump water inlet branch, weeds etc. by pulverizing foreign material cooperating of cutter and chopping disk, can not stop up the water inlet of sewage pump, there is not the solid impurity of larger volume in the sewage that is drawn out of, makes things convenient for next step sewage disposal.
2, the utility model has solved the problem that existing sewage pump causes stuck shutdown cleaning easily, the service life that also can guarantee motor.
3, of the present utility model simple in structure, working stability is reliable, and long service life is applicable to various sewage pumps.
