Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, and in particular to a mining water recycling equipment based on water saving and energy conservation. Background Art

[0002] In the mining production process, the generation of wastewater is inevitable. These wastewaters usually contain a large amount of suspended solids, heavy metal ions and other harmful substances. If they are directly discharged into the environment, they will not only cause serious damage to the ecosystem, but also waste a lot of water resources. Therefore, how to achieve effective treatment and recycling of mining wastewater has become an important issue that needs to be solved in the current mining field.

[0003] Traditional mining wastewater treatment methods mostly use physical, chemical or biological means, such as precipitation, filtration, adsorption, oxidation, etc., but these methods often have problems such as low treatment efficiency, high energy consumption, high operating costs and secondary pollution. In addition, due to the complex and variable composition of mining wastewater, traditional treatment methods are often difficult to adapt to the treatment needs of wastewater with different flow rates and pressures, which limits their promotion and use in practical applications.

[0004] In order to solve the above problems, people began to explore new mining wastewater treatment and recycling technologies. Among them, mining water recycling equipment based on the concept of water and energy saving has gradually attracted attention. This type of equipment usually achieves effective treatment and recycling of mining wastewater through a series of sophisticated designs and innovative technical means, and has high energy efficiency, flexibility and adaptability.

[0005] However, there are still some shortcomings in the mining water recycling equipment currently on the market. For example, some equipment cannot realize energy recovery and utilization when treating wastewater, resulting in high energy consumption; some equipment has poor impurity separation effect, making it difficult to ensure that the treated water quality meets the recycling standards; and some equipment has high maintenance costs, which is not conducive to long-term stable operation. Summary of the invention

[0006] The present invention relates to a mining water recycling device based on water saving and energy conservation, which utilizes the impact force of wastewater itself to drive a water wheel to rotate, thereby not only realizing the kinetic energy conversion of wastewater, but also cleverly realizing energy recovery and utilization through a permanent magnet synchronous motor.

When the water wheel is fully powered by the impact of the wastewater from the wastewater inlet pipe, the permanent magnet synchronous motor generates electricity, and the permanent magnet synchronous motor generates electricity and transmits it to an external electric energy storage device for storage. When the water wheel is insufficiently powered by the impact of the wastewater from the wastewater inlet pipe, the permanent magnet synchronous motor drives the water wheel to rotate to increase power.

The outer dragging magnetic block has different magnetic properties from the cleaning scraper block, and the cleaning scraper block inside the outer dragging magnetic block is dragged to follow the movement.

The sediment cleaning auger rotates to transport the sediment collected by the first sedimentation plate and the second sedimentation plate to the sediment discharge pipe for discharge.

[0017] The present invention provides a mining water recycling device based on water saving and energy saving, which has the following beneficial effects:

[0018] First, the equipment uses the impact force of the wastewater itself to drive the water wheel to rotate, which not only realizes the kinetic energy conversion of the wastewater, but also cleverly realizes energy recovery and utilization through the permanent magnet synchronous motor. When the wastewater has sufficient power, the permanent magnet synchronous motor is used as a generator, and the generated electric energy can be transmitted to an external electric energy storage device for storage, thereby realizing energy recovery and reuse, with high energy efficiency. When the wastewater power is insufficient, the permanent magnet synchronous motor can be converted into an electric motor mode to drive the water wheel to continue rotating, ensuring the continuous and stable operation of the equipment. This design enables the equipment to adapt to the treatment needs of wastewater with different flow rates and pressures, and has high flexibility and adaptability.

[0019] Secondly, the equipment realizes the continuous transportation of wastewater and preliminary impurity separation through the coordinated use of siphon pumping pipe and water delivery propeller. During the transportation process, the heavier impurities such as stones in the wastewater are thrown into the cavity between the centrifugal base and the centrifugal closure cover by the centrifugal force, thereby realizing the preliminary impurity separation and providing clearer wastewater for subsequent treatment steps. This design not only improves the efficiency of wastewater treatment, but also reduces the difficulty and cost of subsequent treatment steps.

[0020] In addition, the equipment also adopts a combination design of a cleaning scraper and an external drag magnetic block to achieve continuous cleaning of impurities on the centrifugal base. The cleaning scraper is made of magnets, and its edge is tangent to the centrifugal closure and the centrifugal base, ensuring effective cleaning of impurities. By dragging the external drag magnetic block, the cleaning scraper is used to follow the movement of the cleaning scraper, and the impurities are scraped and sent to the slag discharge pipe in one direction for discharge. This design not only simplifies the cleaning steps, but also improves the cleaning efficiency, ensuring the long-term stable operation of the equipment.

[0021] In terms of wastewater treatment, the equipment achieves deep sedimentation treatment of wastewater through the design of two-stage sedimentation plates. The wastewater is first subjected to the initial sedimentation effect of the first sedimentation plate, where heavier impurities and particles are deposited. Subsequently, the wastewater continues to flow to the second sedimentation plate, which is staggered with the first sedimentation plate to further sediment the wastewater. This design not only improves the sedimentation efficiency, but also ensures that impurities and particles in the wastewater can be fully removed, thereby obtaining relatively clear clean water. Finally, the treated clean water is discharged through the clean water discharge pipe, realizing the recycling of wastewater, which has high environmental benefits and economic value.

[0022] In summary, the water-saving and energy-saving mining water recycling equipment of this embodiment realizes the effective treatment and recycling of mining wastewater through a series of exquisite designs and innovative technical means, and has high energy efficiency, flexibility and adaptability. At the same time, the equipment also has the advantages of simple structure, easy operation, low maintenance cost, etc., and provides a new solution for the treatment and recycling of mining wastewater.

[0046] Among them, one side of the hydraulic disc box 2 is fixedly connected to a wastewater inlet pipe 201 outwardly along the tangential direction, and the other end of the wastewater inlet pipe 201 is connected to the mining wastewater discharge pipe;

[0047] At least twenty-four water wheels 202 are installed horizontally and rotatably in the inner cavity of the water-dynamic disc box 2. The wastewater entering from the wastewater inlet pipe 201 impacts the water wheel 202 to rotate. The lower end of the rotating shaft of the water wheel 202 passes downward through the water-dynamic disc box 2 and is fixedly connected to the rotating shaft of the permanent magnet synchronous motor 3. When the water wheel 202 is fully powered by the impact of the wastewater from the wastewater inlet pipe 201, the permanent magnet synchronous motor 3 generates electricity, and the permanent magnet synchronous motor 3 generates electricity and transmits it to an external electric energy storage device for storage. When the water wheel 202 is insufficiently powered by the impact of the wastewater from the wastewater inlet pipe 201, the permanent magnet synchronous motor 3 drives the water wheel 202 to rotate to increase the power.

[0048] A water delivery propeller 402 is provided in the inner cavity of the lower end of the siphon pumping pipe 4 near the water-driven disc box 2, and the lower end of the water delivery propeller 402 is fixedly connected to the upper end of the rotating shaft of the water wheel 202;

The centrifugal separation port 401 is located in the cavity between the centrifugal base 5 and the centrifugal sealing cover 6. Stone particles contained in the wastewater transported upward by the water supply screw 402 are thrown into the cavity between the centrifugal base 5 and the centrifugal sealing cover 6 through the centrifugal separation port 401 during the upward transport process and are collected on the centrifugal base 5.

[0050] Wherein, a cleaning scraper 601 is annularly slidably installed in the area between the inner cavity of the centrifugal sealing cover 6 and the lower end of the centrifugal base 5, and the cleaning scraper 601 is made of a magnet, and the edges of the cleaning scraper 601 are tangent to the centrifugal sealing cover 6 and the centrifugal base 5 respectively;

[0051] Two annular clamping rings 602 are installed at intervals at the lower end of the outer end cone of the centrifugal sealing cover 6, and an outer dragging magnetic block 603 is slidably clamped between the upper and lower clamping rings 602. The outer dragging magnetic block 603 has different magnetic properties from the cleaning scraper block 601. The cleaning scraper block 601 inside the outer dragging magnetic block 603 is dragged to move with it. A slag discharge pipe is vertically provided at the bottom of the inner cavity of the centrifugal sealing cover 6 where the outer dragging magnetic block 603 passes. The cleaning scraper block 601 rotates to scrape the collected impurity stone particles unidirectionally to the slag discharge pipe for discharge.

The second sedimentation plate 702 and the first sedimentation plate 701 are in a staggered state, and the two sedimentation plates 702 are below the first sedimentation plate 701. An overflow connecting port 704 is opened below the position where the second sedimentation plates 702 are connected to the side wall of the sedimentation box 7. The overflow connecting port 704 is connected to the inner cavity of the clean water overflow box 8. A vertical reagent injection pipe 703 is fixedly installed at the upper middle end of the sedimentation box 7, and a liquid level sensor 705 is provided at the top position of the inner cavity of the sedimentation box 7. The inner cavity of the sedimentation box 7 is full of water.

[0053] Among them, the connection between the lower end of the inner cavity of the clean water overflow box 8 and the overflow connecting port 704 is an inclined structure to prevent sediment in the water from passing through the clean water overflow box 8. A clean water discharge pipe 801 is fixedly installed on the outer wall of the clean water overflow box 8 near the upper end.

[0054] Embodiment 2. On the basis of embodiment 1, the sediment collection box 9 is an isosceles trapezoidal structure that is wide at the top and narrow at the bottom. A sediment discharge motor 901 is fixedly installed on the side wall at one end of the sediment collection box 9. A spiral sediment cleaning auger 903 is laterally installed at a lower position in the inner cavity of the sediment collection box 9. A downward sediment discharge pipe 902 is fixedly connected to one end of the bottom of the sediment collection box 9 away from the sediment discharge motor 901. The sediment cleaning auger 903 rotates to transport the sediment collected by the first sedimentation plate 701 and the second sedimentation plate 702 to the sediment discharge pipe 902 for discharge.

[0055] The working principle of this embodiment:

[0056] The equipment is first firmly installed at a designated location through a support frame 1 to form a complete wastewater treatment system. When mining wastewater enters the water-driven disc box 2 in a tangential direction through the wastewater inlet pipe 201, its impact force drives the water wheel 202 to start rotating. The number of water wheels 202 is at least twenty-four, ensuring that the wastewater can fully impact and drive the water wheel to rotate. The rotation of the water wheel 202 not only realizes the kinetic energy conversion of the wastewater, but also connects to the permanent magnet synchronous motor 3 through its rotating shaft to realize energy transmission.

[0057] When the wastewater inlet pipe 201 provides sufficient wastewater power, the rotation of the water wheel 202 drives the permanent magnet synchronous motor 3 to be used as a generator, and the generated electric energy is transmitted to the external electric energy storage device for storage, thereby realizing energy recovery and utilization. When the wastewater power is insufficient, the permanent magnet synchronous motor 3 is converted into the motor mode, driving the water wheel 202 to continue rotating, thereby ensuring the continuous operation of the equipment.

[0058] At the same time, the water delivery propeller 402 in the siphon pumping pipe 4 rotates with the rotation of the water wheel 202, and the wastewater is pumped upward from the hydraulic disc box 2 to the sedimentation tank 7. In the process of upward transportation, the heavier impurities such as stones in the wastewater are affected by the centrifugal force and are thrown into the cavity between the centrifugal base 5 and the centrifugal sealing cover 6 through the centrifugal separation port 401, thereby achieving preliminary impurity separation.

[0059] In order to clean the impurities collected on the centrifugal base 5, a cleaning scraper 601 is installed in a circular sliding manner in the area between the inner cavity of the centrifugal sealing cover 6 and the lower end of the centrifugal base 5. The cleaning scraper 601 is made of a magnet, and its edge is tangent to the centrifugal sealing cover 6 and the centrifugal base 5, ensuring effective cleaning of impurities. By dragging the outer drag magnetic block 603, the cleaning scraper 601 is made to follow the movement by utilizing the magnetic difference between the cleaning scraper 601 and the cleaning scraper 601, and the impurities are scraped and sent to the slag discharge pipe in a unidirectional manner for discharge, thereby realizing continuous cleaning of impurities.

[0060] After the wastewater enters the sedimentation tank 7, it is first subjected to the preliminary sedimentation effect of the first sedimentation plate 701, where heavier impurities and particulate matter are deposited. Subsequently, the wastewater continues to flow to the second sedimentation plate 702, and the second sedimentation plate 702, which is staggered with the first sedimentation plate 701, further sediments the wastewater. After two stages of sedimentation, the relatively clear wastewater enters the clean water overflow tank 8 through the overflow connection port 704. In the clean water overflow tank 8, the sediment in the wastewater is blocked by the inclined bottom structure of the tank to prevent it from entering the clean water discharge pipe 801. Finally, the treated clean water is discharged through the clean water discharge pipe 801, realizing the recycling of wastewater.

[0061] At the same time, the impurities and particles settled at the bottom of the sedimentation box 7 are collected by the sediment collection box 9. A spiral sediment cleaning auger 903 is installed at a lower position in the inner cavity of the sediment collection box 9 and rotates horizontally. When the sediment accumulates to a certain extent, the sediment discharge motor 901 drives the sediment cleaning auger 903 to rotate, and the impurities and particles are transported to the sediment discharge pipe 902 for discharge, thereby realizing the continuous operation of the equipment and the regular cleaning of impurities.
