The sand and gravel separator mainly consists of six parts: feeding tank, mixing separator, water supply system, screening system, slurry homogenization, recycling and waste slurry reuse system. When the residual concrete and water enter the tank, circulating water is continuously injected. Under the impact of water flow, the mixture slurry enters the separator with the water inlet and outlet, and the residual concrete is fully cleaned.
Brief introduction of equipment
Cement slurry water continuously flows out of the outlet at the bottom of the separator and into the slurry tank through the slurry guide groove. Driven by the spiral blades in the mixer separator, the cleaned sand and stones are separated and discharged into the feeding pool through their respective outlets. The cement slurry water flowing into the slurry pool from the slurry trough is measured in proportion to the clear water by superposition method to reuse the separated sand, stone and slurry water. When separating sand and stone, sufficient water should be washed to make the stone content less than 1% and the sand content less than 3%. Although the fine material composition of the separated sand and stone decreases and the gradation changes, its proportion in the material yard does not affect its use.
In JGJ63-2006 "Water Standard for Concrete", the Ministry of Construction divides the water used for concrete mixing into drinking water, surface water, groundwater, washing water for equipment of concrete enterprises and sea water, and takes each technical index of water used for concrete mixing as a series of regulations. According to these regulations, we test the indexes of recycled slurry water and then use them for reproduction. The sand and gravel separator manufactured by our company has simple structure, but its design is exquisite. The inner liner is cleaned by stainless steel screen mesh and drum type. It has strong processing capacity and a large amount of feeding material will not produce blocking phenomenon. The sand and stone are separated clean, and there is no residual fly ash on the surface. The stone discharged from the outlet can be directly reused. Electrical control is simple and reliable, which can meet the requirements of different users and provide different supporting electrical interfaces. In order to facilitate users to carry out various in-depth treatment of waste concrete.
It is mainly used for the cleaning of mixing truck used in concrete mixing station and the separation, collection and reuse of sand, stone and mud in waste. It can effectively solve the problem of concrete pollution, and economically and reasonably save valuable building resources. It is an indispensable auxiliary recycling equipment for concrete mixing station. Sandstone separator is mainly composed of separation system, water supply and drainage system, electronic control system and lubrication system. The separating system adopts the rolling screen with the best separating effect at present, and is equipped with automatic stone-sweeping mechanism and the most advanced photoelectric automatic control system. The machine is mainly used for the cleaning of mixing truck in concrete mixing station and the separation and recycling of waste concrete, sand and water. The use of the device can thoroughly solve the problem of waste concrete pollution and save resources. Not only can the sand, stone and slurry in the waste concrete of mixing truck be separated and cleaned automatically at one time, but also the sand, stone and water can be reused. Sewage can be recycled through three-stage sedimentation tank and then pumped into the machine after sedimentation. The zero discharge of sewage can be completely realized, which not only saves resources, but also protects the environment. In a real sense, the design of the machine is reasonable and the maintenance is convenient. With low power consumption and high return on investment, it is the most ideal environmental protection and energy saving product for mixing station.
