With the continuous improvement of environmental awareness, slurry pumps are more and more widely used in the environmental protection industry. Slurry pump is a kind of equipment capable of conveying high-concentration solid particle mixture, which is usually used in industries such as mud, sludge, wastewater treatment, coal mines and metal mines. In the environmental protection industry, slurry pumps can be used in the following aspects.
1. Sludge Treatment
Sludge is solid waste produced during the treatment of domestic sewage and industrial wastewater, containing high concentrations of organic matter and microorganisms. In order to prevent the harmful substances in the sludge from polluting the environment, safe and efficient treatment must be carried out. Slurry pumps can transport sludge from collection tanks, sludge thickening tanks, etc. to processing equipment, such as filter presses, centrifuges, etc., for filtration, drying, etc. The following is the general operation process of slurry pump in sludge treatment:
-
First of all, the slurry pump needs to be inspected and maintained to ensure its normal operation. At the same time, it is necessary to clean and maintain the conveying pipeline to ensure that the sludge can pass through the pipeline smoothly.
-
Secondly, sludge is usually collected from domestic wastewater, industrial wastewater, sludge thickening tanks, etc. In the sludge collection tank, equipment such as a scraper machine can be used to concentrate the sludge into one area, which is convenient for the slurry pump to absorb.
-
Third, install the slurry pump on the edge of the collection tank or the sludge thickening tank, use the suction function of the pump to suck the sludge into the pump, and then transport the sludge to the next treatment equipment.
-
Finally, the sludge transported to the treatment equipment is further processed, such as press filtration, centrifugation, etc., to remove water and convert it into solid waste. Treated sludge can be used for fertilizer or landfill.
2. Mine Tailings Treatment
During the mining process, a large amount of waste residue and tailings will be produced. These substances contain a large amount of heavy metals and harmful substances. If they are directly discharged into the environment, they will cause serious pollution. Slurry pumps can transport tailings from mines to treatment plants, such as flotation machines, dehydrators, etc., for separation, concentration and other treatments. The following is the general operation process of slurry pump in mine tailings treatment:
-
First of all, the slurry pump needs to be inspected and maintained to ensure its normal operation. At the same time, the pipeline needs to be cleaned and maintained to ensure that the slurry can pass through the pipeline smoothly.
-
Second, tailings slurry is typically produced from a mine's beneficiation plant or flotation plant. In the tailings collection pool, equipment such as scraper machines can be used to concentrate the tailings slurry in one area, which is convenient for the slurry pump to absorb.
-
Then, install the slurry pump on the edge of the tailings collection tank, use the suction function of the pump to suck the tailings slurry into the pump, and then transport the tailings slurry to the next processing equipment.
-
Finally, the tailings slurry transported to the processing equipment is further processed, such as tailings thickening, drying, etc., to convert it into solid matter. The treated tailings solids can be landfilled or recycled to achieve the purpose of environmental protection and resource utilization.
3. River Dredging
Silt in the river can hinder the flow of water and even cause the flow to reverse. In order to maintain the smooth flow of the river, it is necessary to clean up the silt. Slurry pumps can pump out the sludge, and then transport it to the treatment site for treatment, such as filtration, thickening, etc. The following is the general operation process of the slurry pump in river dredging:
-
First of all, the slurry pump needs to be inspected and maintained to ensure its normal operation. At the same time, it is necessary to determine the suction destination and delivery route, and set up corresponding pipelines and joints on site.
-
Secondly, place the slurry pump at the position where dredging is required, and use the suction function of the pump to suck solid materials such as silt and sediment into the pump. A variety of different types of suction heads are available to suit different terrains and silt types.
-
Then, the sucked silt, sediment and other solid materials are transported to the destination, and various types of transport pipes and joints can be used, such as rubber hoses, metal hoses, etc.
-
Finally, the solid materials such as silt and sediment transported to the destination are further processed, such as drying, screening, etc., to remove moisture and impurities. The processed solid material can be used to make fertilizer or landfill. Special attention should be paid to the relevant environmental regulations and standards when dumping solid materials such as silt and sediment to ensure safe disposal and discharge of waste.
4. Production of Environmentally Friendly Building Materials
In the production of environmentally friendly building materials, a large amount of waste materials, such as industrial waste residues and coal gangue, are used. Slurry pumps can transport these waste materials to the production line for reuse. The following is the general operation process of the slurry pump in the production of environmentally friendly building materials:
-
First of all, the slurry pump needs to be inspected and maintained to ensure its normal operation. At the same time, it is necessary to arrange the delivery pipes and joints in proper positions to facilitate delivery and use.
-
Secondly, the solid materials and liquids to be transported are mixed according to a certain ratio to make raw materials for building materials. Different mixing equipment can be used, such as mixers, blenders, etc.
-
Then, install the slurry pump at the outlet of the mixing equipment, use the suction function of the pump to suck the building material raw materials into the pump, and then transport it to the next processing equipment or to the building material production site.
-
Finally, the building material raw materials transported to the building material production site are further processed, such as extrusion molding, pressing molding, etc., to produce environmentally friendly building material products. Environmentally friendly building material products can be used in fields such as construction and decoration, and have good environmental protection performance and quality.
Conclusion
In short, the slurry pump is widely used in the environmental protection industry. It can not only improve the efficiency of environmental protection equipment, but also reduce environmental pollution. Therefore, the position of the slurry pump in the environmental protection industry is becoming more and more important.
