Abstract

The utility model discloses an impeller for a sewage pump. The impeller comprises a round top plate and a plurality of bending blades which are integrally and radially arranged on the top plate and are in different heights, wherein the bending blades include high blades, middle blades and lower bladders; and both the middle blades and the high blades have sharp edges. The impeller has the advantages that the sewage pump adopting the impeller has higher guidance efficiency and can effectively wash out the sediment. The wash-out ability is effectively improved through simply changing the structure of the impeller, and the impeller can be manufactured by a manufacturer quickly and effectively at a low cost.

Description

The impeller that is used for pollution discharge pump

Technical field

The utility model relates to the pump field, and relates more specifically to a kind of impeller that is used for pollution discharge pump.

Background technique

In sewage disposal system, pollution discharge pump is a utilization delivery means comparatively widely.Conventional pollution discharge pump links to each other with motor through main shaft, and has the emery wheel that is enclosed within order on the main shaft, following impeller and last impeller.When motor starting, emery wheel, following impeller and last impeller just rotate through main shaft drives.In addition, the rotation generation electric current of emery wheel, following impeller and last impeller guides deposition to get in the lower bottom base.When deposition is passed the inlet on the lower bottom base, the emery wheel deposition of just milling.When the lower blade chamber guided to the upper blade chamber, the centrifugal force that deposition just provides through last impeller was rushed out lower bottom base in the deposition that will mill.Yet the boot efficiency of this conventional pollution discharge pump is lower, and the deposition regular meeting be accumulated in the pump, thereby can result in blockage.

The model utility content

To the problem that above-mentioned existing technology exists, the utility model provides a kind of pollution discharge pump, and it has higher boot efficiency, and can effectively deposition be gone out outside the pump.

To achieve these goals, the technological scheme that the utility model adopts is: a kind of impeller that is used for pollution discharge pump comprises circular top board and radially and integratedly is arranged on a plurality of curved vane on the top board that a plurality of curved vane have different height.

As preferably, a plurality of curved vane comprise high blade, middle blade and the low blades that is provided with in order.

As preferably, middle blade and high blade all have sharp edges.

Compared with prior art, the advantage of the utility model is: use the pollution discharge pump of this impeller to have higher boot efficiency, can go out deposition outside the pump effectively; Impeller has improved the ability of going out effectively through changing structure simply, makes that MANUFACTURER can be fast and make impeller efficiently, and has been lowered into cost.

Embodiment

To combine accompanying drawing that the utility model is described further below.

Referring to Fig. 1, Fig. 2 and Fig. 3, the impeller 2 that is used for pollution discharge pump 3 comprises circular top board 21 and radially and integratedly is arranged on a plurality of curved vane 22 on the top board 21.Top board 21 is for to have the plectane at center, and is suitable for the main shaft 311 on the assembled motor 31 vertically.Axis hole 211 with notch 212 is limited to the center of top board 21.

A plurality of curved vane 22 are formed on the bottom surface of top board 21, and have three kinds of different height, a in the blade 22 wherein, and b, f, g are low blades, the c in the blade 22, e, h and j are middle blade, and d in the blade 22 and i are expressed as high blade.In addition, blade c, e, h and j and blade d and i be inclined-plane 23 respectively, and low blades does not have the inclined-plane.That is to say that middle blade and high blade all have sharp edges.

Referring to Fig. 4 and Fig. 5, impeller 2 is suitable for being installed in the vane room 321 at pollution discharge pump 3 bases 32 places.The axis hole 211 of top board 21 vertically engages the main shaft 311 on the motor 31.Wherein, lower bottom base 32 has at the deposition inlet 322 of at and is limited to the outlet of side-walls, so that link to each other with conduit 325 with switching connector 324.

When the motor in the pollution discharge pump 3 31 started, main shaft 311 drives impeller 2 clockwise directions rotated and produce eddy current, and therefore suction is deposited in the vane room that is deposited to lower bottom base 32 321 in the cesspool 4.Deposition is gone out vane room 321 through the higher hydraulic pressure of the centrifugal force of blade rotation generation and the turbulent flow generation during the rotation, and wherein turbulent flow is produced by the curved vane with different heights 22.Then, deposition is drawn cesspool 4 through flow passage 323, switching connector 324 and conduit 325.

According to above description, the impeller that is used for pollution discharge pump has the following advantages:

Blade roughly is made up of three curved vane 22 with different heights at least, makes impeller 2 have sufficient boot efficiency.The centrifugal force that deposition produces through impeller 2 rotations is gone out the lower bottom base 32 of pollution discharge pump 3.

Impeller has improved the ability of going out effectively through changing structure simply, makes that MANUFACTURER can be fast and make impeller efficiently, and has been lowered into cost.

To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiments shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
