Slag removal mechanism for water tank

Abstract

The invention discloses a slag removal mechanism for a water tank. The slag removal mechanism for the water tank comprises a draining pump and a slag grinding mechanism, the draining pump comprises a pump case, the slag removal mechanism is characterized in that a pump neck is formed on the pump case, the inner diameter of the pump neck is smaller than the upper side and the lower side, and the slag grinding mechanism is arranged in the pump neck. The slag grinding mechanism is arranged in the pump neck of the pump case, a powerful water flow is formed due to the sudden change of the diameter of the pump neck, then a first hydrodynamic impeller is driven to rotate rapidly, a better slag grinding effect is achieved, and the blockage of a pipeline is avoided; two layers of slag baskets are arranged, meshes of the lower layer are much finer to guarantee smooth drainage, the residue slag entering a circulated pipeline structure or a drainage pipe is reduced to further avoid blockage of the pipeline; two sets of slag grinding knifes and a hydrodynamic impeller structure are arranged, so that the two slag grinding knifes form a shearing force to better cut the residue slag into pieces.

Description

technical field [0001] The invention relates to a water tank, in particular to a slag discharge mechanism for the water tank. Background technique [0002] Existing dishwashers, fruit and vegetable cleaning machines, etc., are a device that sprays cold or hot water onto dishes, fruits and vegetables, etc. to remove dirt adhering to dishes, fruits and vegetables, and dishes, fruits and vegetables usually include Pumps and nozzles that spray wash water. Because there are many residues such as vegetable leaves or rice grains on the surface of the dishes, or there are many dirt on the surface of the fruits and vegetables, the sink type washing machine will leave the residues at the bottom of the washing machine after cleaning the dishes, fruits and vegetables, although it can be cleaned through the structure. The adjustment will collect the residue in the slag basket, but the user still needs to manually take out the slag basket for cleaning, which brings a lot of trouble to th...

Problems solved by technology

[0004] However, in the above-mentioned centrifugal pump, the auxiliary impeller driven by water flow is arranged upstream of the water flow, and the inner diameter of the outer end of the conical tube is larger than the inner diameter of the inner end. Therefore, when the water flow passes through, the rotational speed of the auxiliary impeller is relatively slow, and the cutter cuts the slag. The effect is poor, and the cut aquatic plants directly enter the pump body, and there is still a risk of clogging; in addition, there is only one set of impeller and cutter structure, so that the volume of aquatic plants and other cuts is limited to a small extent
