Description

Novel sewage pump

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of water pump, particularly a kind of novel sewage pump.

Background technique

Pollution discharge pump is a kind of Pump and Electromotor disjunctor, and the pump series products worked under simultaneously slipping into liquid, compared with general horizontal pump or vertical sump pump, pollution discharge pump compact structure, floor space are little.Installation and maintenance are convenient, and large-scale pollution discharge pump is typically equipped with automatic lotus root locking device can carry out Auto-mounting, and it is quite convenient to install and keep in repair.Continuous operation time is long.Pollution discharge pump is due to pump and motor coaxle, and rotatable parts are lightweight, and the load (radial direction) of therefore bearing bearing is relatively little, and the life-span is more much longer than general pump.There is not the problem such as cavitation damage and water.A bit very large convenience is brought to operator particularly.Vibration noise is little, and electric machine temperature rise is low, environmentally safe.But the pump housing of common pollution discharge pump easily blocks and pollution discharge capability is bad.

Summary of the invention

The purpose of this utility model there are the problems referred to above for existing technology, proposes one and not easily block and the good novel sewage pump of pollution discharge capability.

The purpose of this utility model realizes by following technical proposal: novel sewage pump, comprise motor and the pump housing, described pump body inner shaft is to being fixed with rotating shaft, the described pump housing comprises feed-water end and waterexit end, it is characterized in that, impeller and shredding mechanism is provided with successively in the described pump housing, described shredding mechanism comprises moving knife and stationary knife, described moving knife and described impeller are all connected mutually with described rotating shaft, described rotating shaft is fixed with helical feeding roller, described feeding roller is positioned at the upside of described impeller, the upper end of described feeding roller is positioned at described waterexit end place.

Operationally, driven by motor axis of rotation, by the rotation of impeller by the sewage of feed-water end toward drainage in the pump housing, rotating shaft simultaneously drives the rotation of moving knife, moving knife and stationary knife is made to shred solid matter in sewage, avoid blocking, drive feeding roller to be carried toward waterexit end by sewage by rotating shaft simultaneously, there is the advantage that working pressure is large and pollution discharge capability is good.

In above-mentioned novel sewage pump, described feed-water end place is fixed with filtering table and described filtering table and described rotating shaft are coaxially arranged.By arranging filtering table, tentatively can filter the sewage at feed-water end place, avoiding the blocking in the pump housing.

In above-mentioned novel sewage pump, described stationary knife is plate-like and is provided with some water channels excessively in the middle part of it, and the described edge crossing water channel is blade.Stationary knife is plate-like, and the water channel excessively in the middle part of it is blade, has good chopping result and is convenient to the advantage of location.

In above-mentioned novel sewage pump, the quantity of described moving knife is three and evenly arranges centered by the axis of described rotating shaft, and the upper side of described moving knife abuts in the downside of described stationary knife.

In above-mentioned novel sewage pump, the upper end of the described pump housing is fixed with coupling sleeve, and the housing of described motor is connected on described coupling sleeve, and the main shaft of described motor is connected with described rotating shaft mutually through described coupling sleeve.By arranging coupling sleeve, being convenient to the connection of motor and the pump housing, having and connecting conveniently advantage.

Compared with prior art, this novel sewage pump has the following advantages:

1, cross the rotation of impeller by the sewage of feed-water end toward drainage in the pump housing, rotating shaft simultaneously drives the rotation of moving knife, makes moving knife and stationary knife shred solid matter in sewage, avoids blocking;

2, drive feeding roller to be carried toward waterexit end by sewage by rotating shaft simultaneously, there is the advantage that working pressure is large and pollution discharge capability is good;

3, by arranging coupling sleeve, being convenient to the connection of motor and the pump housing, having and connecting conveniently advantage.
