Description

Revolve the antiwind sewage pump of scissors

Technical field

The utility model belongs to pump technology field, relates to a kind of sewage pump, particularly one and revolves the antiwind sewage pump of scissors.

Background technique

In the industrial production, submersible pump, owing to can meet many special purposes, is all widely used in every profession and trade, diving pump structure also obtain constantly along with improvement perfect.Submersible pump is when sewage effluent, generally all can there are various scum silica frost, plastic article and other are as fibers such as cotton yarn, the rope made of hemp, shreds in sewage, or other analogs, these impurity directly enter in submersible pump and are easy to cause effluent discharge to have some setbacks and affect the normal work of submersible pump, cause damage in impeller, impurity also can be wound around impeller, causes the damage of motor, reduces the working efficiency of submersible pump and shortens working life.

In order to prevent fiber at submersible pump shaft during operation impeller, technician improves diving pump structure, installs cutting device additional, can effectively cut the impurity in sewage in the water inlet of submersible pump.The cutting device of many water pump manufactories to submersible pump has research in the market, but be all on the basis of original submersible pump mostly, install cutting device additional and carry out practical function, cutting device structure and pump hydraulic structure matching problem are not furtherd investigate further, there is cutting effect difference, the impurity entering to the pump housing can not be pulverized completely.

Summary of the invention

The purpose of this utility model there are the problems referred to above for existing technology, propose a kind of good cutting effect, anti-winding ability strong revolve the antiwind sewage pump of scissors.

The purpose of this utility model realizes by following technical proposal:

Originally the antiwind sewage pump of scissors is revolved, comprise the pump housing with pump chamber, the motor being located at pump housing top and lower end and stretch to pump shaft in pump chamber, described pump shaft is arranged with the impeller being positioned at pump chamber, water intake and the impeller of the pump housing are oppositely arranged, it is characterized in that, the described pump housing is provided with the cutting tool rest for shutoff water intake, described cutting tool rest is provided with the axial hole be communicated with water intake, be provided with the cutting cutter hub of the big up and small down structure be connected on pump shaft in described axial hole, the outside of described cutting cutter hub is provided with screw blade.After starting of pump station, Electric-motor driven pumps axle rotates, pump shaft impeller and cutting cutter hub rotate, water enters in pump chamber through axial hole under the effect of impeller, impurity in water is shredded under screw blade with the effect of cutting tool rest as long fibre, bag, grass, cloth etc., then discharges from the water outlet of the pump housing.Because cutting cutter hub becomes up big and down small structure, one is facilitate impurity to enter between cutting cutter hub and cutting tool rest, and two is that the impurity preventing from not shredding enters in pump chamber, and the impurity in water, in the process rotated, can fully shred by screw blade.

Revolve in the antiwind sewage pump of scissors above-mentioned, described screw blade is two and is symmetrically set in the outside of described cutting cutter hub.

Revolve in the antiwind sewage pump of scissors above-mentioned, the madial wall of described axial hole is provided with two reverse acting spiral blades contrary with the rotation direction of screw blade respectively, and the reverse acting spiral blade symmetry described in two is located on the madial wall of described axial hole.

Because screw blade is contrary with the rotation direction of reverse acting spiral blade, when motor tells that running drives screw blade to rotate, screw blade and reverse acting spiral blade form cross-shear, the impurity such as the long fibre in sewage, bag, grass, cloth were just fully shredded before entering impeller, and cutting effect is very good.Screw blade and reverse acting spiral blade all adopt high-intensity high-speed Steel material, are processed by special processing, have that hardness is high, cutting edge is sharp and nonabradable advantage, effectively improve cutting performance, more durable.

Revolve in the antiwind sewage pump of scissors above-mentioned, described impeller adopts half-open rotary flow type structural design.Form open space in pump chamber, greatly can strengthen passing capacity, anti-blockage capability and anti-winding ability, and can also effectively the impurity decomposed and tore be discharged, without the need to adding filter screen on the pump housing from pump housing water outlet.

Revolve in the antiwind sewage pump of scissors above-mentioned, in described cutting cutter hub, there is the mounting hole that arrange corresponding to pump shaft, the lower end of described pump shaft stretches in this mounting hole, be provided with limited step in described mounting hole, described limited step is provided with the connecting bolt for limited step being connected in pump shaft end.

Revolve in the antiwind sewage pump of scissors above-mentioned, the top of described cutting cutter hub has four circumferential spacing preiections evenly arranged, the bottom of described impeller has the circumferential limited part stretched between circumferential spacing preiection, and cutting cutter hub described under this circumferential limited part and circumferential limit convex role and impeller circumference are fixed.

Revolve in the antiwind sewage pump of scissors above-mentioned, described cutting tool rest is provided with assembly department, and described assembly department is bolted on the downside of the pump housing.

Compared with prior art, originally revolve the antiwind sewage pump of scissors to have the following advantages:

Cutting cutter hub becomes up big and down small structure, both impurity had been facilitated to enter between cutting cutter hub and cutting tool rest, can prevent again the impurity do not shredded from entering in pump chamber, screw blade and reverse acting spiral blade form cross-shear, shear ability is strong, and the impurity in water fully can be shredded, impeller adopts half-open rotary flow type structural design, elevator pump cavity space, can strengthen passing capacity, anti-blockage capability and anti-winding ability greatly.
