Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] refer to figure 1 and figure 2 , the present embodiment includes the impeller body 9 fixed with the blade 3, the impeller front cover plate 2, the impeller rear cover plate 4, the shaft 11 that plays a connecting role, the bearing 8 that fixes the impeller body 9 to ensure its smooth operation, and the impeller front cover plate 2 A circular reamer frame 6 is provided at the feed inlet of the feeder, and blade-type reamers 1 that are evenly distributed are fixed inside the circular reamer frame 6. The blade of the blade-type reamer 1 is forward-rotating, and the blade is right There are blades on the side facing the direction of flow.

[0015] The tip of the vane reamer 1 points radially to the axis of the inlet channel.

[0016] When installing with the pump body, the annular reamer frame 6 used to fix the blade reamer 1 is integrated with t...

Abstract

The invention provides a sludge pump impeller with integrated reamer and impeller, comprising an impeller main body, an impeller front cover plate, an impeller back cover plate, a shaft with the function of connecting, and a bearing for fixing the impeller to guarantee stable running; a torus reamer framework is installed in the feed inlet of the impeller front cover plate; blade-like reamers arranged uniformly are fixed inside the torus reamer framework; the blades of the blade-like reamers are in the form of forward rotating; blade edges are opened on the right side of the blades facing the direction of the flow. The invention is simple in structure, and convenient in installation, and can prevent the blockage of the flow passage inside the pump, and increases the efficiency, flow amount and lift of the pump.

Description

technical field [0001] The invention relates to a sludge pump impeller, in particular to a sludge pump impeller in which a reamer and an impeller are integrated. Background technique [0002] At present, there are mainly two types of impellers for sludge pumps, one is a centrifugal fully closed impeller, and the other is a semi-closed impeller. Their inlets are horn-shaped and large. During operation, the feed The mouth or flow channel is easily blocked by slightly larger hard mud or grass vines, resulting in downtime. In addition, due to the high density and viscosity of the extract, the negative pressure in the impeller channel is too low, the suction is not enough, and the flow and lift often cannot meet the actual needs. [0003] Chinese patent CN2672326 discloses a double reamer cutting pump, which relieves the current situation that the pump flow channel is often blocked to a certain extent, but its inlet size is relatively reduced, and the reamer takes up too much sp...
