Problems solved by technology

The device cannot screen the sand and gravel in a large particle size section, and the applicable range is narrow
[0005] Due to the limited working length of the currently used sand screening device, one screening cannot fully separate the sand and gravel with large and small particle sizes, and repeated screening operations are required, and the work efficiency is low; due to the irregular shape of the sand and gravel, the surface is relatively sharp , the impact with the gro

Embodiment 1

[0033] This embodiment provides a multi-level sand washing equipment, including a sand loading hopper 1, a conveying device 2 for transporting the sand in the sand loading hopper 1 to a high place, a three-stage sand filtering device, a sand storage room 4, Drainage ditch 5, wastewater recovery tank 6, sand washing device 7;

[0034]The tertiary sand filter device includes three steps and a screen washing device inclined downward in the longitudinal direction, and a bracket 8 for fixing the screen washing device; the screen washing device includes a drum with small holes on the outer wall 9. The drum driving device is located directly below the drum 9 and is arranged obliquely downward. A baffle 11 for sand and water flow;

[0035] Helical blades 12 are fixed on the inner walls of each of the drums 9, and the pitch of the helical blades 12 at the high position is greater than the pitch of the helical blades 12 at the low position; the driving device of the drum 9 includes a r...

Embodiment 2

[0041] This embodiment provides a multi-level screening and washing equipment. Compared with Embodiment 1, the difference is that the cross-sectional shape of the baffle plate 11 is L-shaped; the small hole on the drum 9 is circular; the The sand washing pipeline includes a water storage main pipe connected to the suction pipe, and a spraying branch pipe corresponding to each drum 9 arranged on the water storage main pipe; The inside of the drum 9 is parallel, and the spraying branch pipe is evenly equipped with nozzles on the side wall facing the drum 9; the waste water recovery pool 6 is connected with an external water supply device; The protective net in the gutter 5.

[0042] The L-shaped baffle plate 11 can effectively prevent the sand and gravel at the outlet end of the drum 9 from falling onto the bottom wall 10 and destroy the screening effect; the sand and gravel inside the drum 9 can be sprayed with water through the spraying branch pipe, on the one hand, it can was...

Abstract

The invention discloses multi-level sand sifting equipment which comprises a sand filling hopper, a transfer device for conveying sand in the sand filling hopper up, a multi-level sand filtering device, a sand stacking room, a drainage ditch, a waste water recovery pond and a sand washing device. By arranging spiral blades on the inner wall of a roller, the moving path of gravels is prolonged effectively and the gravels are fully screened. The pitch among the spiral blades is arranged reasonably according to the grain sizes of the gravels, so that the screening effect is guaranteed. By arranging a water tank on the ground of the sand stacking room to buffer falling gravels, the ground is protected. By means of a detachable partition plate, the capacity of a compartment is adjusted reasonably according to the screening condition of the gravels, so that the utilization ratio of space is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building material processing equipment, and in particular relates to a multi-level sand washing equipment. Background technique [0002] With the development of the construction industry. The demand for sand used in the domestic construction industry has increased. The construction industry uses a large amount of sand materials, and has different demands for sand materials of different particle sizes. Therefore, the sand material needs a sand screening process before it is used. The purpose is to separate the coarse sand from the fine sand. The method is inefficient and labor-intensive; on the other hand, the sand often contains mud and other harmful impurities, such as saline and alkali, which can corrode steel bars and affect the life of the building. Therefore, the mud and harmful impurities in the sand need to be cleaned . [0003] Chinese Patent No. CN201810048245.X discloses a water-saving multi-...
