Description

Water retaining device for sand washing dehydration tailing recycling all-in-one machine

Technical Field

The utility model belongs to the technical field of mechanical equipment, and particularly relates to a water retaining device for a sand washing and dewatering tailing recycling all-in-one machine.

Background

The water content of the sand is 4 percent, the water content of the stone is 2 percent, the water content is 4 to 6 percent if the sand is generally stored for a period of time, and if the green sand just transported can reach 10 to 15 percent, the sand is not uniform. The sand and stone in the ready-mixed concrete are respectively 800-1100kg/m³The amount of water used, per 1% of water content, has the effect of 8-11kg of water used in the concrete. Particularly, the water content of the sand is greatly changed, and if the water content is not frequently detected and the water consumption for stirring is timely adjusted, the slump, the pumpability and the strength of concrete of each disc can be greatly fluctuated. During the production process of the machine-made sand, a large amount of water is adopted to wash the aggregate. The water content of the finished sand which is just produced is about 12% -15%, and excessive free water needs to be removed. The water content of the sand can be reduced from about 25% to about 15% at the initial stage by adopting a linear vibrating screen for dehydration. At present, when the sand and water mixture is discharged to the screen surface of the dewatering screen by the feeding water tank and the swirler, the water content is too much, and the sand is taken out of the discharge port when moving ahead along with the screen surface, so that the water content of the sand is too high.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the utility model.

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1-4, the present invention provides a technical solution: a water retaining device for a sand washing and dewatering tailing recycling all-in-one machine comprises a screen box 1, wherein the screen box 1 comprises a screen baffle 11, side plates 10, a front cross beam 12, a middle cross beam 13 and a rear cross beam 14, the screen baffle 11 is arranged at the bottom of the screen box 1, the left side and the right side of the screen baffle 11 are respectively provided with the side plates 10, and the front cross beam 12, the middle cross beam 13 and the rear cross beam 14 are sequentially arranged on the screen baffle 11 from front to back; the side plate 10 is provided with an edge protection plate 2, and the screen retainer 11 is sequentially provided with a front screen 3, a screen bar 4, a rear screen 5 and a side screen 7.
