Product information
Jilin Wanjiyuan Environmental Protection Equipment Co., Ltd. was established in 2008. It is a comprehensive enterprise specializing in the design, manufacturing, sales, operation and maintenance of environmental protection equipment. After more than ten years of innovation and development,, launched: The third-generation (sand and gravel separation + pulp and water recycling) system, truly achieving zero emission of wastewater and waste pulp from ready-mixed concrete production.
Wanji supports the third-generation "sand and gravel separation + pulp and water recovery" system,This exclusive patented technology has a subversion of traditional treatment methods. It can decompose and recycle all the waste residue and wastewater generated by the mixing station every day, and the recovered sand, gravel and slurry water can be completely reused in concrete production.
1. core advantages
(1) Independent sand and gravel separation system: Without the cumbersome steps of precipitation and pressure filtration, sand and stone are decomposed immediately, and the decomposition efficiency can reach 50t-120t/h. The energy consumption per unit cubic amount of waste decomposition is extremely low. The sand and stone are recycled are clean, separated thoroughly, and the reuse rate reaches 100%.
(2) The patented technology cyclone separator can efficiently separate fine sand that cannot be separated by traditional equipment, and the separation standard reaches 0.075mm, reaching the industry leading position. Traditional sand and gravel separators cannot process fine sand particles, and require a three-stage sedimentation tank to form solid waste residue after long-term precipitation, which is discharged for treatment. All recycled water slurry is used for reproduction, which will not cause any pollution or damage to the environment, eliminates the process of dredging and removing blood stasis, and can save a lot of money for enterprises.
(3) In addition to cleaning the tank truck, the remaining large amount of concrete can also be quickly decomposed, solving the problem of residual material consumption; there is a circulating water supply system. When operating, only the button is activated without waiting, and the proportioned slurry immediately enters the water scale., saving time and efficiency; fully automatic operation mode requires no manual intervention, and the labor cost is extremely low.
(4) Low civil construction costs: Eliminate the three-stage sedimentation tanks and filter presses of traditional equipment, maximize the utilization of the idle space under the mixing building, covering an area of about 250 square meters, saving at least 30% of land resources, and saving civil construction costs by about 15- 200,000 yuan.
2. process flow
(1) After the mixer truck returns to the mixing station, use the recycled circulating water from the new concrete decomposition and recycling equipment to clean the tank of the mixer truck.
(2) After stirring and cleaning, unload the mixture in the tank into the recovery station separation screw, and use an ore screen to separate sand and gravel.
(3) Transfer the gravel belt from the ore plates to the gravel outlet.
(4) Spirally transfer the sand separated by the ore sieve to the sand outlet.
(5) Use a cyclone separator to put the separated slurry water into a water storage tank.
(6) The water slurry enters a steel plate paddle water tank with a stirrer, and the stirrer automatically mixes it regularly to prevent the water slurry from settling and solidifying.
(7) Use pipeline transfer pumps to automatically transfer recycled water to the transfer storage box of the mixing building.
(8) The concrete recycling and cleaning process will be fully automatic system operation.
3. System composition and purpose
The third generation (sand and gravel separation + slurry and water recovery) system consists of sand and gravel separation system, slurry and water recovery system, pipeline transportation system, and control system. The sand and gravel separation system includes guide troughs, ore spiral screens, belt conveyors, screw conveyors, cyclone separators, etc. The slurry water recovery system consists of slurry water storage parts such as slurry water tanks, primary water tanks and secondary water tanks. It can intermittently stir the recovered slurry water to prevent precipitation.
The specific functions of each component are as follows:
1）guide chute: When the mixer truck returns to the station, it fills the waste into the guide trough after adding water. 2-5 vehicles can be designed to clean at the same time.
2）ore spiral screen: Waste passes through here for gravel separation.
3）belt conveyor: Send the gravel separated by the ore spiral screen to the stacking area.
4）screw conveyor: Decompose the coarse sand in the water slurry and transport it to the sand stacking area.
5）cyclone separator: Quickly decompose fine sand particles in the water slurry transported from the secondary water tank.
6）slurry tank: The final treated slurry water is stored here, and the recycled water can be used for production through the mixing building control room. The tank is equipped with a stirrer for regular mixing. A pneumatic valve is installed below the tank to regularly discharge the thick slurry water that has settled at the bottom of the tank into a water tank for regular circulation, ensuring a relatively constant concentration of slurry water and solving the problem of regular cleaning of the traditional underground slurry pond as it accumulates thicker and thicker. The problem of cleaning out.
7）underground water tank: The water slurry decomposed by the sand and gravel separator flows into the water tank and is then transported to the cyclone separator by the mortar pump.
8）pipeline transportation system: The circulating water supply system directly supplies the slurry water to the mixing building water scale, which improves production efficiency, is convenient and quick, and the pipes are not easy to block.
9）control system: Fully automatic operation mode is stable and reliable; with winter operation mode, it can ensure normal operation in cold areas in winter.
The sales network covers 27 provinces (including autonomous regions and municipalities directly under the Central Government) across the country, and the strictly controlled quality and service have won widespread praise for Wanji Aid! Relying on its excellent performance in the industry, Wanjiyuan has established cooperation with large groups such as Sany, China Railway, Jinyu, China Hydropower, China Building Materials, Huaxin Cement, Yunnan Construction Investment, Shanghai Construction Engineering, and China Resources Cement.
