Description

Sand washer

The utility model relates to a kind of sandstone surface earth and saline and alkaline equipment of cleaning, and is specially adapted to building trade.

The develop rapidly of building industry is had higher requirement to the quality of construction material, and wherein the requirement to sandstone then mainly comprises clay content and granular size etc.Because the earth on sandstone surface, saline and alkaline grade can constitute the corrosion to building, influences its antidetonation, shake-proof ability, even influences the life-span of building, and therefore, for improving construction quality, the necessity of washed-out sand is generally acknowledged.There is the outlet of large batch of sand every year in China, is manyly all kept outside of the door because of technical indicator is undesirable.But China does not still have special-purpose washed-out sand equipment at present, and the sand of outlet mostly is with the man-made recovery, sieves and washes, and has both expended great amount of manpower, material resources and financial resources, and the sand that is sifted out still has and does not much reach requirement.

In order to improve the washed-out sand quality, and alleviate working strength of workers, the purpose of this utility model is to provide a kind of special-purpose sand washer, with the earth of removing the sandstone surface effectively and saline and alkaline.

The technical solution of the utility model is:

A kind of sand washer, comprise the transmission device of forming by motor, shaft coupling, reductor and the large and small sprocket wheel that is connected by chain, on the output shaft of transmission device, be disposed with washed-out sand impeller and wheel bucket, outside along impeller and wheel bucket is provided with give a dinner of welcome groove and the overflow launder that is used to collect sewage effluent that is used to stir the sand material, and feed hopper.

Described washed-out sand impeller includes at least three wheel discs that link with output shaft, by connecting gusset along the axial affixed one-tenth wheel skeleton of the outer circumferential edges of each wheel disc, even 16 helical blades that distribute on this cylindrical outer surface, and the helical angle of blade is preferably 25 °.

The described bucket of taking turns is the wheel ladder that connects firmly mutually with wheel skeleton one side, and 16 hoppers that are arranged in order along wheel ladder outer circumference surface constitute.An end portion of 16 helical blades on the washed-out sand impeller not with the wheel bucket that links on 16 hopper positions being distributed corresponding one by one.

Each is welded into polyhedron by eight block plates above-mentioned hopper, and the inclined plane that shakes out is 30 °.

Effect of the present utility model is conspicuous.

At first because its helical angle of helical blade of washed-out sand impeller is reasonable in design, can make sandstone under the promotion of helical blade with suitable speed to the wheel square sheet of paper used for painting or calligraphy to motion; Again since each helical blade termination all corresponding to the entrance location of each hopper that is distributed on the wheel bucket, take out of so the sandstone of cleaning can be struggled against by wheel automatically.The design on the shape of hopper and the inclined plane that shakes out has guaranteed that sandstone can successfully be poured on the dewatering screen, has realized the overall process of mechanization washed-out sand thus.This machine project organization is reasonable, easy for operation, and the washed-out sand ability is big, the labor productivity height; Both alleviated working strength of workers greatly, and also guaranteed the clean rate of sandstone, production efficiency and quality are significantly increased.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is a washed-out sand impeller and the structural representation of taking turns bucket in the utility model;

Fig. 4 is a C-C cross section view among Fig. 3, expresses the wheel disc and the wheel skeleton structure of washed-out sand impeller;

Fig. 5 and Fig. 6 are respectively B-B section and A-A cross section view among Fig. 3, have expressed the structure of wheel bucket with different angles.

Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.

Referring to Fig. 1 and Fig. 2.The utility model comprises motor 1, the transmission device that shaft coupling 2, reductor 3 and the large and small sprocket wheel 5,6 that is connected by chain 4 are formed.In the present embodiment, power of motor is got 11 kilowatts, and rotating speed is 970 rev/mins; The reductor gearratio is 180, and output speed is 5.39 rev/mins, makes the output shaft rotating speed be kept to 1.68 rev/mins by 1: 5 big minor sprocket.Be disposed with washed-out sand impeller 8 and wheel bucket 9 on the output shaft 7, its diameter is respectively 2.2 meters and 3.4 meters.Outside at impeller and wheel bucket is provided with the groove 10 of giving a dinner of welcome that is used to clean stirring sand material.In order to collect and discharge the sewage after the washed-out sand, in the outside of giving a dinner of welcome groove 10, be provided with overflow launder 11 away from a side of wheel bucket, sewage can be entered in the collecting-tank by the delivery port in this groove.Feed hopper 12 in the present embodiment is positioned at a side of the groove 10 of giving a dinner of welcome, and is used for providing sandstone and water to the groove of giving a dinner of welcome continuously.

The structure of washed-out sand impeller 8 can demonstrate from Fig. 3 and Fig. 4.Four wheel discs 13 with spoke are fixed on the output shaft 7 successively, by connecting gusset 14 along the axial affixed one-tenth wheel skeleton of the outer circumferential edges of each wheel disc 13, are evenly distributed with 16 helical blades 15 along this cylindrical outer surface.The helical angle of each helical blade is preferably 25 °.

As can be seen from Figure 3 the annexation of wheel bucket 9 and washed-out sand impeller is promptly fixedlyed connected with the inner periphery of wheel bucket one side along the wheel disc outer rim that is positioned at washed-out sand impeller one end.Wheel bucket 9 is made up of 16 identical hoppers of taking turns ladder and be uniformly distributed on its outer circumference surface, sees Fig. 5 and Fig. 6.Each hopper is welded into polyhedron by eight blocks of

difform steel plates

16,17,18,19,20,21,22,23.Along the excircle of wheel bucket, each hopper has charging aperture, and the rotation along with the wheel bucket can make sandstone enter in the hopper; Along the inner periphery of wheel bucket, each hopper is provided with discharging opening, and the inclined plane of discharging (angle promptly shakes out) is 30 °, so that sandstone is routed up continuously with the rotation of wheel bucket, enters on the dewatering screen that is arranged at wheel bucket middle part; Along the both sides of wheel bucket width, each hopper is sealing, and is positioned at the hopper side near washed-out sand impeller one side, is made of three inclined planes, and purpose is for ease of shaking out, and avoids occurring shaking out the dead angle and sandstone is trapped in the hopper.

In addition, on the above-mentioned washed-out sand impeller termination of 16 helical blades be respectively with the wheel bucket that is joined on 16 hopper positions one to one, in order to shaking out.

In the present embodiment washed-out sand ability of sand washer can reach the 200-300 ton/hour, the sand clay content after the cleaning only is 0.1%, and has disposed the composition such as saline and alkaline on sandstone surface effectively, has improved the exhausted cleanliness of sand.Owing to adopt the utility model, realized the mechanization washed-out sand, both can scientifically economize on water, also improved labor productivity, reduced the consumption on the human and material resources, have in building industry and promote and the use prospect.
