Description

Technical Field

[0001] The utility model relates to the technical field of mine sewage treatment, in particular to an ultrafiltration device for a mine sewage treatment station. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, the inclined shafts, vertical shafts and horizontal shafts in the underground development of mines are also called mines. The size of the mine field and the determination of the mine production capacity and service life are one of the key issues that must be solved in the mine design.

[0003] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. Most of my country's coal mines are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants that grow in a certain geological age, gradually accumulate into thick layers in a suitable geological environment, and are buried under water or in mud and sand, and are formed by natural coalification over a long geological period.

[0004] As we all know, water resources are polluted during coal mining. A large amount of coal powder, rock dust, and domestic water for construction workers are produced during mining. If a large amount of untreated excessive sewage is directly discharged, it will directly pollute groundwater sources and damage the groundwater system.

[0005] Although sewage treatment devices or systems are used for sewage treatment in existing mining, the treatment efficiency is low and the treatment effect is poor. Therefore, it takes a long time to treat the sewage and the user experience is poor. Utility Model Content

[0006] The utility model provides an ultrafiltration device for a mine sewage treatment station, which solves the above-mentioned technical problems.

[0007] The utility model solves the above-mentioned technical problems as follows:

[0008] A mine sewage treatment station ultrafiltration device comprises an outer shell, a barrel, an ultrafiltration element and a water distributor, wherein a water outlet hole is provided on the outer side of the barrel, and an outer shell is provided on the outer side of the barrel below the water outlet hole, wherein a buffer chamber and a receiving chamber are provided in the outer shell, and an ultrafiltration element is placed in the receiving chamber, and an outlet pipe is provided at the bottom end of the outer shell, and a water inlet pipe is connected to the bottom end of the barrel, and a water distributor is rotatably mounted on the water inlet pipe through a rotating seal, and the water distributor is located in the barrel, and water outlets are provided around the water distributor, and the water outlets are along the tangent direction of the water distributor.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a guide groove is provided at the top of the ultrafiltration element.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] Improve filtration efficiency: The setting of the guide groove can guide the sewage to form a more uniform flow at the top of the ultrafiltration element. This helps to ensure that the entire ultrafiltration element surface can be fully utilized and improve filtration efficiency. The water flowing through the guide groove is more likely to cover the entire area of ​​the ultrafiltration element, reducing the possibility of dead corners or partially unfiltered areas.

[0013] Slow down the accumulation of impurities: The presence of the guide groove can help slow down the accumulation of impurities on the surface of the ultrafiltration element. By guiding the water flow, the guide groove helps to evenly disperse the suspended particles on the surface of the ultrafiltration element, preventing excessive accumulation of particles in a certain area and affecting the filtration effect.

[0014] Extend the life of the ultrafilter element: The design of the guide groove helps reduce the burden on the surface of the ultrafilter element, allowing it to bear the water flow and filtration action more evenly. This helps to extend the service life of the ultrafilter element and reduce maintenance frequency and replacement costs.

[0015] Reduce maintenance costs: Due to the presence of the guide groove, the surface of the ultrafiltration element is easier to clean during operation. This reduces the complexity of maintenance and reduces the time and cost required for maintenance.

[0016] Improve system stability: The design of the diversion groove can promote the water flow to form a more stable flow on the ultrafiltration element. This helps to prevent uneven water flow or blockage, and improve the stability and reliability of the entire mine sewage treatment system.

[0017] Furthermore, the bottom end of the cache cavity is connected to the outside through a water outlet pipe.

[0018] The beneficial effects of adopting the above further scheme are:

[0019] Smooth discharge of treated water: The bottom of the buffer chamber is connected to the outside through the outlet pipe, which allows the treated water to be smoothly discharged to the external environment or the next treatment stage. This helps maintain the continuous operation of the entire sewage treatment system.

[0020] Flexible control of water discharge: The interconnected design allows for more flexible control of water discharge. By adjusting the opening degree or other parameters of the outlet pipe, the discharge rate can be adjusted according to actual needs to meet the requirements under different treatment conditions.

[0021] Reduce system pressure: The presence of the buffer chamber allows the treated water to be stored for a short time before discharge. This helps to alleviate sudden changes in system pressure and avoid adverse effects on the system due to instantaneous water flow shock.

[0022] Convenient maintenance and cleaning: The outlet pipe is connected to the outside, which makes system maintenance and cleaning more convenient. When maintenance or cleaning is required, the water flow can be directly guided through the outlet pipe, reducing the downtime of the treatment station and improving the maintainability of the system.

[0023] Avoid secondary pollution of sewage: The interconnected design helps to prevent the treated water from being polluted again. By quickly discharging the treated water to the outside, the possibility of external contamination during the discharge process can be reduced, maintaining the effectiveness of water quality treatment.

[0024] Furthermore, the water outlets are evenly distributed on the water distributor.

[0025] The beneficial effects of adopting the above further scheme are:

[0026] Adjustable water flow direction: By rotating the seal and rotating the installation design, the angle of the water distributor can be adjusted to change the direction of the water flow. This helps to adapt to different treatment conditions and needs and improve the flexibility and adaptability of the system.

[0027] Uniform water flow distribution: The water outlets are evenly opened around the water distributor and distributed along the tangent direction to ensure that the water flow is evenly distributed along the entire water distributor surface. This helps to avoid dead corners and local untreated areas, increase the coverage area of ​​the water flow, and thus improve the uniformity of water quality treatment.

[0028] Maximize treatment effect: The rotating seal rotating water distributor design can cover a larger treatment area. Combined with the uniform distribution of the water outlets, the treatment capacity of the water distributor is maximized, ensuring that each water outlet distributes the water flow evenly and improving the water quality treatment effect.

[0029] Adapt to different treatment requirements: Since the angle of the water distributor is adjustable, the angle and distribution of the water flow can be adjusted according to the actual treatment requirements. This allows the system to adapt to different water qualities, flow rates and treatment conditions, improving the system's adaptability and treatment efficiency.

[0030] Reduced water velocity differences: The angle of the distributor can be adjusted to help reduce the difference in water velocity across the distributor. This helps avoid over-treatment in some areas and under-treatment in others, and improves water flow consistency.

[0031] Improve system stability: The adjustable design helps improve the stability of the entire system. By adjusting the angle of the water distributor, it can better adapt to different processing conditions, reduce system fluctuations, and improve system reliability.

[0032] Furthermore, the water inlet pipe is connected to a water source to be treated through a delivery pump.

[0033] The beneficial effects of adopting the above further scheme are:

[0034] Convenient water diversion: The connection design of the water inlet pipe allows the bottom of the barrel to be easily connected to the water source to be treated. This helps to simplify the water diversion process and ensure that the water source can enter the treatment system smoothly.

[0035] Adapt to different water sources: Through the use of transfer pumps, the system can adapt to the water level differences of different water sources. The transfer pump can provide sufficient water flow pressure to ensure that the water source can flow steadily into the treatment system, even if the water source has large differences in height.

[0036] Flexible control of water inlet speed: The presence of the delivery pump allows for flexible control of the water inlet speed. By adjusting the operating parameters of the delivery pump, the water inflow speed can be adjusted according to the actual treatment needs and water quality conditions, improving the adaptability and flexibility of the system.

[0037] Reduce system pressure: The transfer pump helps relieve system pressure, especially when it is necessary to increase the water flow rate or deal with large height differences in the water source. This can reduce the system's dependence on the water source and improve the stability of the entire system.

[0038] The beneficial effects of the utility model are:

[0039] Superior ultrafiltration effect: The device is equipped with an ultrafiltration element, which is designed to effectively filter tiny particles, suspended matter and other impurities in mine wastewater. The setting of the diversion groove helps to guide the water flow through the entire surface of the ultrafiltration element, maximize the filtration effect, and improve the water purification level.

[0040] Water flow guiding design: The design of the buffer chamber and the holding chamber in the housing takes into account the guiding property of water flow to ensure that water flows evenly over the ultrafiltration element. This helps to maximize the filtering capacity of the ultrafiltration element, prevent local blockage or accumulation of fine particles, and improve the overall filtering efficiency.

[0041] Distributor Design: The use of distributors within the unit is an important design decision. By rotating the distributor with a rotating seal, a more uniform water flow distribution can be achieved. The uniform distribution of outlets along the perimeter of the distributor ensures uniformity of the treated water flow, preventing dead spots or localized undertreatment.

[0042] Easy to connect and discharge: The bottom of the device is equipped with an outlet pipe and an inlet pipe, which are connected to the external system through these pipes. This allows the entire treatment station to be easily integrated into the mine sewage treatment system. The outlet pipe is connected to the outside through the buffer chamber and the bottom of the shell, while the inlet pipe is connected to the water source to be treated through the delivery pump, forming a tightly connected treatment process.

[0043] Compact structure: The design of the housing, barrel, ultrafiltration element, water distributor and other components are carefully laid out to ensure that the entire device is compact. This helps to reduce the footprint, which is particularly important for applications with limited space such as mines. The compact design also helps to simplify maintenance and operation processes.

This helps to ensure that the entire surface of the ultrafiltration element 5 can be fully utilized and improve the filtering efficiency. The water flowing through the guide groove 2 is more likely to cover the entire area of ​​the ultrafiltration element 5, reducing the area that may form a dead angle or a partially unfiltered area. The presence of the guide groove 2 can help to slow down the accumulation of impurities on the surface of the ultrafiltration element 5. By guiding the water flow, the guide groove 2 helps to evenly disperse the suspended particles on the surface of the ultrafiltration element 5, preventing the particles from accumulating too much in a certain area and affecting the filtering effect. The design of the guide groove 2 helps to reduce the burden on the surface of the ultrafiltration element 5, so that it can more evenly withstand the water flow and filtering action. This helps to extend the service life of the ultrafiltration element 5 and reduce the maintenance frequency and replacement cost. Due to the presence of the guide groove 2, the surface of the ultrafiltration element 5 is easier to clean during operation. This reduces the complexity of maintenance and reduces the time and cost required for maintenance. The design of the guide groove 2 can cause the water flow to form a relatively stable flow on the ultrafiltration element 5. This helps to prevent uneven or blocked water flow and improve the stability and reliability of the entire mine sewage treatment system. The bottom end of the shell 1 is provided with an outlet pipe 6, and the bottom end of the cache chamber 9 is connected to the outside through the outlet pipe 6. The bottom end of the cache chamber 9 is connected to the outside through the outlet pipe 6, which enables the treated water flow to be smoothly discharged to the external environment or the next treatment stage. This helps to maintain the continuous operation of the entire sewage treatment system. The connected design makes it possible to control the discharge of the water flow more flexibly. By adjusting the opening degree or other parameters of the outlet pipe 6, the discharge speed can be adjusted according to actual needs to meet the requirements under different treatment conditions. The presence of the cache chamber 9 allows the treated water flow to be stored for a short time before discharge. This helps to alleviate the sudden change of system pressure and avoid adverse effects on the system due to instantaneous water flow impact. By connecting to the outside through the outlet pipe 6, the system maintenance and cleaning can be carried out more conveniently. When maintenance or cleaning is required, the water flow can be directly guided through the outlet pipe 6 to reduce the downtime of the treatment station and improve the maintainability of the system. The connected design helps to prevent the treated water flow from being contaminated again. By quickly discharging the treated water to the outside, the possibility of external contamination during the discharge process can be reduced, and the effectiveness of water quality treatment can be maintained. The bottom end of the barrel body 4 is connected to the water inlet pipe 7, and the water inlet pipe 7 is connected to the water source to be treated through a delivery pump. The connection design of the water inlet pipe 7 enables the bottom end of the barrel body 4 to be easily connected to the water source to be treated. This helps to simplify the water diversion process and ensure that the water source can smoothly enter the treatment system. Through the use of a delivery pump, the system can adapt to the water level differences of different water sources.The delivery pump can provide sufficient water flow pressure to ensure that the water source can flow into the treatment system stably, and can effectively cope with the large difference in the height of the water source. The existence of the delivery pump allows flexible control of the water inlet speed. By adjusting the operating parameters of the delivery pump, the water inflow speed can be adjusted according to the actual treatment requirements and water quality conditions, and the adaptability and flexibility of the system can be improved. The delivery pump helps to relieve the pressure of the system, especially when it is necessary to increase the water flow rate or treat a large height difference of the water source. This can reduce the dependence of the system on the water source and improve the stability of the entire system. A water distributor 8 is rotatably installed on the water inlet pipe 7 through a rotating seal. The water distributor 8 is located in the barrel 4. Water outlets 11 are opened around the water distributor 8. The water outlets 11 are evenly distributed on the water distributor 8. The design of rotating the seal and rotating the installation can adjust the angle of the water distributor 8, thereby changing the direction of the water flow. This helps to adapt to different treatment conditions and requirements and improve the flexibility and adaptability of the system. The water outlets 11 are evenly opened around the water distributor 8 and distributed along the tangent direction to ensure that the water flow is evenly distributed along the entire surface of the water distributor 8. This helps to avoid dead corners and local untreated areas, increase the coverage area of ​​the water flow, and thus improve the uniformity of water quality treatment. The design of the rotating water distributor 8 with a rotary seal can cover a larger treatment area. Combined with the uniform distribution of the water outlets 11, the treatment capacity of the water distributor 8 is maximized, ensuring that each water outlet 11 evenly distributes the water flow, thereby improving the water quality treatment effect. Since the angle of the water distributor 8 is adjustable, the angle and distribution of the water flow can be adjusted according to actual treatment needs. This allows the system to adapt to different water qualities, flow rates and treatment conditions, improving the adaptability and treatment efficiency of the system. The adjustable angle of the water distributor 8 helps to reduce the speed difference of the water flow on the water distributor 8. This helps to avoid over-treatment in some areas and under-treatment in other areas, and improves the consistency of the water flow. The adjustable design helps to improve the stability of the entire system. By adjusting the angle of the water distributor 8, it is possible to better adapt to different processing conditions, reduce system fluctuations, and improve system reliability. The water outlet 11 is along the tangent direction of the water distributor 8, which makes it easy for the water distributor 8 to rotate through the thrust of the water flow while distributing water, thereby lifting impurities in the barrel body 4 and allowing the water flow to carry the impurities through the water outlet 11 of the barrel body 4 to be drained to the ultrafiltration element 5 for filtration, thereby avoiding dead corners in the barrel body 4.
