Abstract
The invention relates to a pump for smashing sewages, comprising a transmission shaft, a smasher and pump body. A long sleeve is arranged outside the transmission shaft. A connection base connected with a motor is fixed at the top of the long sleeve, and an upper cover connected with the pump body is fixed at the bottom of the long sleeve. The smasher comprises an impeller connected with the lower end of the transmission shaft through a shaft sleeve, the impeller is provided with a plurality of approximately evolvent-shaped circular arc-shaped vanes. Blades are arranged at the end of the lower end of the vanes. The bottom of the pump body is provided with a bottom cover, and the bottom cover is provided with a water inlet. The pump for smashing sewages is characterized in that blades are arranged at the upper end of the vanes. The smasher further comprises an inner plate fixed at the bottom of the upper cover and sleeved on the impeller. Circular arc-shaped upper cutters corresponding to the vanes are arranged on the inner plate. Circular arc-shaped lower cutters corresponding to the vanes are arranged at the water inlet at the upper edge of the bottom cover. The invention has strong smashing strength for sewages, and high efficiency of discharging sewages; in addition, the phenomena that sewages slip and are piled up at the cutting position, and the like are avoided.
Description
Technical field
The present invention relates to a kind of pump, specifically, relate to a kind of pump for smashing sewages.
Background technique
Existing sewer Under Water Pumps is provided with the dirt shredding mechanism mostly, these dirt shredding mechanism is to reach the chopping dirt by the shearing force that produces between the cutting knife of blade bottom and the base plate, because smashing sewages is slow, and the output of dirt is very fast, broken insufficient obstruction that causes the pump housing easily of dirt like this, also have dirt to produce slippage, accumulation in shearing place easily, influence sewage emissions.
Summary of the invention
The purpose of this invention is to provide a kind of contaminant removal effectiveness height, pump for smashing sewages that breaking capacity is strong.
The technical solution used in the present invention is:
Pump for smashing sewages, comprise transmission shaft, the breaker and the pump housing, described transmission shaft is provided with long sleeve pipe outward, the connecting base that the roof anchorage of this long sleeve pipe has the power supply motivation to connect, the bottom is fixed with the loam cake that is connected with the pump housing, described breaker comprises the impeller that is connected with the transmission shaft lower end by axle sleeve, described impeller is provided with many circular arc vanes that roughly are the involute shape, the end, lower end of described blade is provided with blade, described pump housing bottom is provided with bottom, this bottom is provided with water intake, also be provided with blade on the end, upper end of described blade, described breaker also comprises and is fixed on loam cake bottom and is socketed in inner panel on the impeller, described inner panel is provided with many and the corresponding circular arc upper cutter of blade, and described bottom upper edge water intake is provided with many and the corresponding circular arc lower cutter of blade.
Described blade is a double-leaf, and is oppositely arranged.
The bar number of described upper cutter is three.
The bottom that one side end of described lower cutter is provided with blade II, end side is provided with the cutting groove with the lower cutter almost parallel.
The bar number of described lower cutter is three.
Described water intake be shaped as triangle.
The present invention also is provided with blade on the end, upper end of blade, be provided with many and the corresponding circular arc upper cutter of blade on inner panel, is provided with many and the corresponding circular arc lower cutter of blade at bottom upper edge water intake.To smashing sewages the time, produce double-shear between blade on the impeller and inner panel and bottom like this, so not only improved the crashing rate of dirt, and improved contaminant removal effectiveness.
In order further to improve pollution discharge capability of the present invention, preferred two blades of the present invention, and it is oppositely arranged, in order to improve crushing efficiency of the present invention, upper cutter on the inner panel and the lower cutter on the bottom all are preferably three.
In order making better shearing force to be arranged between impeller of the present invention and the lower cutter, be provided with blade II on a side end of lower cutter, the bottom of end side is provided with the cutting groove with the lower cutter almost parallel.
The present invention is in order to make impeller inspiration sewage better, and the present invention is designed to triangle with water intake.
Advantage of the present invention is: strong, the sewer efficient height of the breaking capacity to dirt, and also dirt is difficult in phenomenons such as shearing place generation slippage, accumulations.

Embodiment
Extremely shown in Figure 9 as Fig. 1, pump for smashing sewages, comprise transmission shaft 2, the breaker 3 and the pump housing 1, outside transmission shaft 2, be provided with long sleeve pipe 4, the connecting base 5 that the roof anchorage of this long sleeve pipe 4 has the power supply motivation to connect, the bottom is fixed with the loam cake 6 that is connected with the pump housing 1, breaker 3 comprises the impeller 8 that is connected with transmission shaft 2 lower ends by axle sleeve 7, on this impeller 8, be relatively set with two circular arc vanes 9 that roughly are the involute shape, the end, lower end of this blade 9 is provided with blade 13, be provided with bottom 11 in the pump housing 1 bottom, this bottom 11 is provided with triangle water intake 12, on the end, upper end of blade 9, also be provided with blade 13, breaker 3 also comprises and is fixed on loam cake 6 bottoms and is socketed in inner panel 10 on the impeller 8, this inner panel 10 is provided with three and blade 9 corresponding circular arc upper cutters 14, be provided with three and blade 9 corresponding circular arc lower cutters 15 at bottom 11 upper edge triangle water intakes 12, on a side end of this lower cutter 15, be provided with blade II 16, the bottom 11 of end side is provided with the cutting groove 17 with lower cutter 15 almost parallels.
The present invention is when being used as, actuating motor, impeller 8 high speed rotating, then sewage under the rotation of impeller 8 in water intake 12 enters into the pump housing 1, owing to highly produce the high speed double-shear between the blade 9 on the impeller 8 of rotation and upper cutter 14 on the inner panel 10 and the lower cutter 15 on the bottom 11, bigger dirt is broken under shear action at a high speed, and the sewage that is broken is then transferred out by the impeller under the high speed rotating 8, finishes the broken discharge process of dirt.
