Abstract

The utility model discloses a stepless speed-regulating wheel type sand washing machine, which comprises a hydraulic motor, an impeller, a sand washing tank, a frame and a dewatering screen, wherein the washing tank is arranged on the frame; the dewatering screen is arranged at an inlet of the sand washing tank; and the impeller is arranged inside the sand washing tank and is connected to the hydraulic motor. The hydraulic motor is adopted for stepless speed regulation, and different rotating speeds of the impeller can be set, a sand washing effect is improved, so that a specific production requirement on the sand washing machine, particularly a requirement on strong concrete, can be met. Due to the adoption of a dewatering screen combined feeding tank, manufactured sand to be treated is effectively dewatered; and therefore, the treatment effect is improved. The sand washing machine has a novel structure and is stable to operate.

Description

The wheeled sand washer of stepless speed regulation

[technical field]

The utility model relates to the wheeled sand washer of stepless speed regulation.

[background technology]

At present, domestic building trade adopts sand washer that the earth piece in the sand is washed to improve the credit rating of building sand with sand, satisfies the needs of architectural engineering.The wheeled sand washer of prior art basically all is made up of impeller, reductor, washing groove, frame and motor; Its motor through V-belt, reductor, gear reduction after impeller slowly rotate; Sandstone is got in the washing groove by feeder trough; Under the drive of impeller, roll, and grind the impurity of removing cover sand building stones surface each other, destroy the steam layer that coats sand grains simultaneously; Add water simultaneously, form powerful current, in time impurity and the little foreign matter of proportion are taken away, and discharge, accomplish sandstone material discharge effect from the overfall washing trough.

The wheeled sand washer of prior art can only make the clay content of roughing sand whenever wash in the process of washed-out sand once to reduce by 1%, and the content of clod is difficult to reduce in the roughing sand.And current building trade is with the national Specification of sand, and clay content≤3%, clod content≤2% are so existing wheeled sand washer is difficult to satisfy the requirement of some Important Project project demand C50, C55 or C60 strong concrete.

[utility model content]

The purpose of the utility model solves the problems of the prior art exactly, proposes the wheeled sand washer of a kind of stepless speed regulation, can improve the washed-out sand effect, satisfies in the engineering project purity requirement to strong concrete.

For realizing above-mentioned purpose; The utility model provides the wheeled sand washer of a kind of stepless speed regulation; Comprise hydraulic motor, impeller, washed-out sand groove, frame and dewatering screen, said frame is provided with the washed-out sand groove, and the porch of washed-out sand groove is equipped with dewatering screen; In the washed-out sand groove impeller is installed, impeller is connected to hydraulic motor.

As preferably, said hydraulic motor is installed in a side of frame through support, and is simple in structure, easy for installation.

As preferably, said impeller is the circular colyliform that is evenly distributed with blade on the periphery, and circular wheel is a hollow structure, supports peripheries by some spokes, and simple in structure, washed-out sand is effective.

The beneficial effect of the utility model: the utility model adopts hydraulic motor to carry out stepless speed regulation, can set the various different rotating speeds of impeller, has improved the washed-out sand effect, makes sand washer can satisfy the specific requirement of production, especially to the requirement of strong concrete.Adopt the knockdown feeder trough of dewatering screen, make that pending artificial sand is effectively dewatered, thereby improve treatment effect.The utility model novel structure, running are steadily.

Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.

[description of drawings]

Fig. 1 is the structural representation of the wheeled sand washer of the utility model stepless speed regulation.

[specific embodiment]

Consult Fig. 1, the wheeled sand washer of stepless speed regulation comprises hydraulic motor 1, impeller 2, washed-out sand groove 3, frame 4 and dewatering screen 5; Said frame 4 is provided with washed-out sand groove 3; The porch of washed-out sand groove 3 is equipped with dewatering screen 5, and impeller 2 is installed in the washed-out sand groove 3, and impeller 2 is connected to hydraulic motor 1.Sandstone is got in the washed-out sand groove 3 by dewatering screen 5, under the drive of impeller 2, rolls, and grinds the impurity of removing cover sand building stones surface each other, destroys the steam layer that coats sand grains simultaneously; Add water simultaneously, form powerful current, in time impurity and the little foreign matter of proportion are taken away, and discharge, accomplish sandstone material discharge effect from the overfall of washed-out sand groove 3.Simultaneously, because impeller 2 has adopted the mode of hydraulic motor 1 driving, thereby realized the stepless speed regulation of impeller 2; Therefore; Can realize the work control of sand washer through rotating speed control, thereby improve the service behaviour of sand washer, to reach predetermined engine request impeller 2.

Said hydraulic motor 1 is installed in a side of frame 4 through support.Said impeller 2 is for being evenly distributed with the circular colyliform of blade on the periphery, circular wheel is a hollow structure, supports periphery by some spokes.

The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection domain that scheme after the utility model simple transformation is all belonged to the utility model.
