Abstract
The utility model discloses an axially split pump for pollution discharge, which belongs to the field of fluid machinery and aims to solve the problem of the existing axially split pump that the pump cannot work normally due to an impeller inlet is easy to block when sewage containing a large quantity of impurities is discharged. The axially split pump for the pollution discharge comprises a pump shell composed of a pump body and a pump cover and an impeller arranged on a pump shaft; and agitating devices for cutting off sucked impurities are arranged in a suction chamber of a pump cavity of the pump shell and at an impeller suction opening of the impeller. According to the axially split pump disclosed by the utility model, the impurities in the water can be cut off and smashed by utilizing the agitating devices which rotate at a high speed, so that the aim of discharging the sewage by the pump is achieved. When the axially split pump for the pollution discharge is used for discharging contaminants including straws, paper scraps and the like in the water, the contaminants can be automatically cut off and smashed after the pump is started and the impeller is not blocked by the contaminants, so that the function of discharging the sewage and the contaminants by the axially split pump is realized. The device has the advantages of simple structure and convenience for installation, use and maintenance.
Description
Technical field
The utility model relates to field of fluid machinery, especially for adopting the stirring apparatus through special research, is used for dispatch dirt sewage in the middle-opening pump.
Background technique
The existing centrifugal pump of opening in common is easy to the clogging impeller import and causes pump to work with runner when dispatch contains the sewage of a large amount of foreign material, and in case stop up to remove contamination must remove when safeguarding along in open the face-pumping lid, the very inconvenience of removing contamination.
Pollution discharge pump adopts the sewage Submerged Motor Pumps mostly now, need pump and motor all must be immersed in the sewage, and the flow using scope is little, and is all very inconvenient for the sewage Submerged Motor Pumps operation and maintenance that flow is big slightly.And use the blowdown middle-opening pump of being with stirring apparatus, and the flow using scope is big, and pump and motor are all installed on the ground, and operation and maintenance is all very convenient.
Summary of the invention
The situation that is easy to the clogging impeller import when containing the sewage of a large amount of foreign material and causes pump to work to existing middle-opening pump dispatch; The utility model aims to provide a kind of blowdown middle-opening pump; It can solve the problem of dirt clogging impeller import, can satisfy the needs of various urban sewage dispatch.
Be to realize above-mentioned purpose, the technological scheme that the utility model adopted is: said blowdown middle-opening pump comprises the pump case be made up of the pump housing and pump cover, is contained in the impeller on the pump shaft; Its structural feature is, in the pump chamber suction chamber of pump case, the suction eye place of impeller is equipped with the stirring apparatus that sucks the foreign material chopping.
Further, said stirring apparatus preferably is contained on the pump shaft.
As the priority scheme of the utility model, said stirring apparatus is a plurality of blades of radially loading on pump shaft.
The blade of said impeller adopts existing blowdown blade structure.
By said structure, the pump case of the utility model is divided into the pump housing and pump cover, still adopts the structure of common middle-opening pump, is convenient to install and use and keep in repair; In the water inlet volute chamber of pump case, the ground stirring apparatus that rotates with the axis is installed at the impeller intake place, the stirring blade on the stirring apparatus can cut off and blend getting into dirt before the impeller, gets into impeller channel after making the size decreases of dirt, does not stop up through runner; The impeller that is contained in the pump housing is compared with common middle-opening pump impeller, through strengthening blade pitgh, outlet passage is strengthened, and the easy like this dirt of large-size that lets does not stop up through impeller channel.
Compared with prior art; The beneficial effect of the utility model is: when the utility model makes the dispatch sewage dirt, adopt the blowdown middle-opening pump of being with stirring apparatus to reach the purpose of dispatch sewage dirt, be convenient to install and use and safeguard; And the range of flow of pump dispatch strengthens, and can reach 20000m
3/ h.Avoided effectively that traditional submerged pump need all submergence be again in the sewage with pump and motor, operation and maintenance is all very inconvenient, and the also very little shortcoming of dispatch range of flow.

Embodiment
Below in conjunction with embodiment the utility model is done further to set forth.
A kind of blowdown middle-opening pump, as shown in Figure 1, mainly form by the pump housing 1, impeller 2, stirring apparatus 3, pump cover 4, pump shaft 5.Said stirring apparatus 3 is installed in the pump chamber suction chamber 7 of pump case, suction eye 8 places of impeller 2, and links through axle sleeve and pump shaft 5 and impeller 2; Its middle pump body 1, pump cover 4 are connected into integral body, form the pump chamber of sealing.Said stirring apparatus 3 is used for the chopping of suction foreign material is pumped then, stops up middle-opening pump to prevent foreign material.As shown in Figure 2, said stirring apparatus 3 is a plurality of blades 11 of radially loading on pump shaft 5.The blade of said impeller 2 adopts the blowdown blade structure.
Blowdown middle-opening pump of the utility model and existing common middle-opening pump difference are that its pump chamber suction chamber 7 leans on suction eye 8 places of impeller 2 that stirring apparatus 3 is installed.As shown in Figure 3; The stirring apparatus 3 of the blowdown middle-opening pump of the described stirring apparatus of the utility model; In the time of can the dirt pump chamber suction chamber 7 in the fed sheet of a media being transported to the impeller inlet limit 10 by impeller 2 dirt cut off and blend; Get into impeller channel 6 after the size decreases of dirt through impeller outlet limits 9 and be transported to the delivery side of pump pipeline and make, cut off through impeller channel 6 and not clogging impeller runner 6 of dirt after blending, thereby realized the conveying of sewage dirt.Use the design of this special construction; The problem that is easy to the clogging impeller import when having solved the sewage that uses the middle-opening pump dispatch to contain a large amount of foreign material and causes pump to work; The flow using scope is big, and pump and motor are all installed on the ground, and operation and maintenance is all very convenient.Use the blowdown middle-opening pump of stirring apparatus to carry sewage dirt, need pump and motor all must be immersed in the sewage when also having avoided employing sewage Submerged Motor Pumps to carry sewage dirt, and the little problem of flow using scope.
After the utility model makes pump startup, utilize the stirring apparatus high speed rotating that foreign material in the water are cut off and blend, thereby reach purpose with pump dispatch sewage.When the utility model is used for water and contains dirt such as straw paper scrap, realize cutting off automatically behind the pump startup blending dirt, do not allow the dirt clogging impeller, let the function of middle-opening pump dispatch sewage dirt and reach.This apparatus structure is simple, installation, use, easy to maintenance.
The content that the foregoing description is illustrated is to be understood that to these embodiments and only is used to be illustrated more clearly in the utility model; And be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
