Sand separating and washing all-in-one machine

Abstract

The invention relates to a sand separating and washing all-in-one machine. The machine comprises a vibrating screen box and a filtering assembly arranged in the vibrating screen box, wherein an upperfiltering piece and a lower filtering piece of the filtering assembly are each provided with a water outlet pipe, a water outlet pipe is arranged at a discharging port of the lower filtering piece, the upper filtering piece is provided with two or three water outlet pipes, and the upper and lower water outlet pipes are connected with a main water pipe through valves. According to the machine, 85%of fine particle materials in the total discharge amount can be recovered to the maximum extent, the device has incomparable technical and economic advantages compared with other equipment, fine particles are fully recovered, the problem of resource waste is solved, the workload of a sedimentation tank is reduced, the cleaning cost of the sedimentation tank is reduced, the fine material stacking time is shortened, and therefore the materials can be directly transferred and supplied to the market.

Description

technical field [0001] The invention relates to the field of sludge slurry water, and in particular provides an integrated machine for separating sand and washing sand. Background technique [0002] The waste slurry produced in the construction of construction projects is mainly used to screen the waste slurry with a mud purification device. For example, the mud purification device disclosed in the patent application CN01240225.7 mainly performs sand separation and purification treatment on the waste slurry. The screened mud can be directly reused in construction, and the separated sand and gravel are directly transported to the designated treatment site. The method is the same as above. However, it will bring too much discharge of sand and gravel with mud, which not only wastes resources, but also causes environmental pollution. Another example is the patent application CN201420243125.2, which discloses a screening and washing integrated sand washing machine. The sand rec...

However, it will bring too much discharge of sand and gravel with mud, which not only wastes resources, but also causes environmental pollution

Another example is the patent application CN201420243125.2, which discloses a screening and washing integrated sand washing machine. The sand recovery system combining the sand separator and the sand washing machine can effectively reduce the loss of sand and gravel, so that it can be controlled at 5%. Within -10%, it solves the problem of waste of sand and gravel resources and pollution of the environment, but this combination requires large water consumption and power, requires sedimentation tanks and water storage tanks, and the equipment occupies a large area, so it is not suitable for vigorous promotion.
