Abstract
The utility model discloses a self-suction type crushing centrifuge pump for a vessel, which comprises a pump body, a cutter, a pump shaft, an impeller, a pump cover, a bracket and a motor. The motor is directly connected with the pump body through the bracket, the lower face of the bracket is pressed tightly on the pump cover, and the impeller is installed on the end of a suspension arm of the pump shaft. An axial suction inlet of the pump body is located on the upper portion of the outward side and directly communicated with an impeller inlet at the lower position, and a channel naturally forms a self-suction structure of a built-in water storage cavity of the pump body. The cutter comprises static cutters and dynamic cutters, and three to five static cutters are evenly distributed on the same circumference at the joint portion of the pump cavity and the axial suction inlet. The dynamic cutters are installed at a shaft end of the pump shaft in front of the impeller inlet, and the dynamic cutters rotating along with the pump shaft and the static cutters with fixed position are matched to form a crushing structure of an inner cavity of the pump body. A self-suction structure and the crushing structure are integrated with the pump body, thereby being compact in structure and easy to perform self-suction, saving installation position and consuming little energy. In addition, the suction inlet is in an open structure and not easy to block. The self-suction type crushing centrifuge pump for the vessel is particularly suitable for matching with sewage transferring systems on the vessel.
Description
Technical field
The utility model relates to a kind of water pump, and specifically, the utility model relates to a kind of peculiar to vessel self-priming pulverizing centrifugal pump that is used for sewage transport.
Background technique
During the big-and-middle-sized ship's navigation, work sewage that is produced and domestic sewage all accumulate in the boat bottom bilge tank, treat that ship effluxes after the Unified Treatment behind the port.Under the normal condition, the effluent treatment plant that disposes on the ship is installed on the bilge tank, the sewage in the bilge tank is drawn deliver to the conveying of the necessary use of effluent treatment plant processing pump.Because of the sewage that accumulates in the bilge tank contains impurity, even contain cellulosic foreign material, broken plastic article and some particulate matters.Particularity to sewage transport operating mode on the ship and institute's fed sheet of a media; Existing ship uses the pump of sewage transport system layout for pulverizing centrifugal pump; And pulverizing centrifugal pump aspiration port access self-priming apparatus; External self-priming apparatus can significantly improve the inlet capacity of macerator pump, has created a basic condition for controlling automatically.The pulverizing centrifugal pump of existing sewage transport system layout and self-priming apparatus be for dividing body structure, supporting easily, connect simply, can effectively realize sewage transport.But; Self-priming apparatus of the prior art is positioned at before the macerator pump, and the sewage that self-priming apparatus sucks contains overlength, super large foreign material still without pulverizing treatment in case run into; Self-priming apparatus very easily takes place to be stopped up; Cause sewage transport system down, need do corresponding removal rubbish disposal, could recover normal after waiting to remove barriers and carry.Generally speaking, self-priming apparatus and problem such as pulverize that the centrifugal pump phase separation structure exists that pollution discharge capability is poor, rate of fault high, big energy-consuming and occupation of land are big are with the supporting a certain distance that exists of modern ships.
The model utility content
The utility model is primarily aimed at existing technology and pulverizes the deficiency that centrifugal pump and self-priming apparatus split; A kind of peculiar to vessel self-priming pulverizing centrifugal pump that integrates pulverizing, self-priming structure is proposed; This pump structure is simple, compact, rationally, power consumption less, take up an area of economize, reliable.
The utility model is realized technical goal through following technical proposals.
Self-priming pulverizing centrifugal pump peculiar to vessel, it comprises the pump housing, cutter, pump shaft, impeller, pump cover, carriage and motor.The said pump housing is a horizontal type structure, and passage up is outlet, axially suction port and pump chamber apportion both sides.To the direct connection pump housing, the carriage end face compresses the pump cover that cooperates with pump chamber to said motor by bracket axle, mounted impeller on pump shaft cantilever axle head.Said cutter comprises quiet cutter and moving knife; Quiet cutter is the monolithic knife structure; On the same circumference of pump chamber and axial suction port connecting part, be uniformly distributed with 3～5 quiet cuttves, moving knife is the cutter disk structure, is directly installed on the impeller eye pump shaft axle head before; Moving knife and quiet cutter be relative and reservation matching gap b with blade, and the moving knife and the quiet cutter that rotate with pump shaft constitute the pulverizing structure that is positioned at pump housing inner chamber.Its improvements are: said axial suction port is positioned at a pump housing upper lateral part outwardly, and the axial suction port on the residence is directly linked up the impeller eye of low level, and this passage forms the self-priming structure and pulverizing structure and pump housing integrated setting of built-in storage chamber naturally.
In the said structure, the included angle of quiet cutter and moving knife is 15
0～25
0, preset clearance b=0.02～0.05mm between the blade of quiet cutter and moving knife.
The utility model compared with prior art has following good effect:
1, self-priming structure and pulverizing structure are integrated in the same pump housing compact structure, low cost of manufacture;
2, retaining self-priming structure and pulverizing structure and pump housing integrated setting reduce connecting tube, mounting point province, and suction port is uncovered structure, is difficult for stopping up;
3, utilize the retaining self-priming structure of alternate position spike to realize that self-priming is easy, do not need to join in addition driving power, so power consumption is few.
