Description

Technical Field

[0001] This invention belongs to the field of mine water treatment technology, and relates to an integrated treatment system for mine water sludge and floating oil, as well as an integrated treatment method for mine water sludge and floating oil. Background Technology

[0002] Mine water is groundwater extracted from underground mines during coal mining. It mainly consists of dissolved minerals, suspended particles, and chemical impurities. With the development of coal mining technology, the discharge of mine water is constantly increasing. Direct discharge of untreated mine water leads to water waste and damage to the surface ecological environment. Therefore, promoting the comprehensive treatment and resource utilization of mine water to provide qualified production and domestic water for the local area can effectively alleviate the contradiction between coal resource development and water scarcity. Suspended solids in mine water mainly originate from coal dust, rock dust, and other particulate matter produced during coal mining. These particles, due to their small size, high ash content, and difficulty in settling, not only affect the transparency of the water body but also increase the risk of membrane system fouling, increase the frequency of membrane cleaning, shorten the membrane replacement cycle, and significantly increase the operating costs of enterprises. Secondly, floating oil in mine water mainly comes from lubricating oil and hydraulic oil used in the mining process. If floating oil enters the evaporation and crystallization system, it will reduce evaporation efficiency, further affecting the overall performance and economy of the mine water treatment system. Therefore, effective mine water treatment not only needs to remove sludge and floating oil, but also needs to ensure the long-term stable operation of the treatment system, reduce operating costs, and lay the foundation for subsequent water quality improvement and environmental remediation.

[0003] Existing technologies for treating mine water sludge and floating oil primarily employ physical and chemical methods. Physical methods include sedimentation and filtration, while chemical methods include flocculation and oxidation-reduction. In addition, specialized equipment such as scrapers and skimmers are used to remove sludge and floating oil from mine water. Traditional scrapers are typically trolley-type, with a relatively complex structure, making maintenance and cleaning difficult and requiring significant manual labor, severely impacting operational efficiency. Furthermore, when the volume of sludge from underground water is excessive, coal sludge easily settles. Traditional trolley-type scrapers, operating in a repetitive cycle of raising and scraping within the pool, have low scraping efficiency and are prone to scraping blockages, leading to system failure and increased maintenance costs. Secondly, traditional trolley-type scrapers have relatively high energy consumption, typically requiring substantial power to drive the scraping process. On the other hand, the mud-water interface is blurred during operation of existing scraping equipment, easily disturbing the sludge layer and causing secondary sludge re-floating. In addition, existing equipment also has problems such as lack of integrated oil removal function, large drainage volume during oil skimming, inability to efficiently solve oil and water treatment, and affecting the operation of subsequent processing processes.

[0004] In summary, existing technologies suffer from the problems of difficulty in achieving integrated treatment of mine water sludge and floating oil, as well as high treatment costs and low efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated treatment system for mine water sludge and floating oil, which solves the problems of difficulty in achieving integrated treatment of mine water sludge and floating oil, as well as high treatment costs and low efficiency in the existing technology.

[0006] Another objective of this invention is to provide an integrated treatment method for mine water sludge and floating oil.

[0007] The technical solution adopted in this invention is an integrated treatment system for mine water sludge and floating oil, including a control system. The control system is communicatively connected to a sludge collection and discharge system and a floating oil treatment system. The sludge collection and discharge system includes a submersible reciprocating sludge scraper installed at the bottom of the mine water pre-sedimentation tank. An annular air-stirring sludge hopper is installed at the bottom of the output end of the submersible reciprocating sludge scraper. The annular air-stirring sludge hopper is connected to a wear-resistant slurry pump through a sludge discharge pipe. The floating oil treatment system includes a tubular oil separator installed on the side rail of the tank.

[0008] The invention is further characterized by: The submersible reciprocating sludge scraper includes a sludge scraping module and a power module. The power module includes a hydraulic cylinder. The output end of the hydraulic cylinder is connected to one end of a piston rod. The other end of the piston rod is hinged to one end of a triangular boom. The other end of the triangular boom is connected to the sludge scraping module.

[0009] The corner end of the triangular boom is fixed to the wall of the mine water pre-sedimentation tank by the triangular boom fixing frame.

[0010] The mud scraping module includes a horizontal push rod. One end of the horizontal push rod is connected to the end of the triangular arm away from the piston rod, and the other end of the horizontal push rod is connected to the slide plate. Several wedge-shaped scrapers are arranged parallel to each other on the bottom of the slide plate.

[0011] The sliding plate is slidably connected to the central shaft, which is fixed to the bottom of the mine water pre-sedimentation tank by a fixed plate and a fixed support; the central shaft is set between the horizontal push rod and the sliding plate, and the horizontal push rod is slidably connected to the central shaft; a sludge discharge port is provided between the wedge scraper and the sliding plate.

[0012] The slide plate extends above the annular air-mixing hopper via a fixed support; the annular air-mixing hopper is provided with several air outlets, which are evenly distributed on the annular pipe of the annular air-mixing hopper, and the annular pipe of the annular air-mixing hopper is connected to a compressed air pipeline.

[0013] The tubular oil separator is installed above the mine water pre-sedimentation tank. The tubular oil separator includes a fixed frame, which is movably connected to the side rail of the tank. Rotating wheels are respectively installed at both ends of the fixed frame near the mine water pre-sedimentation tank.

An oil suction hose is installed between the oil scraper and the oil collection trough, and the oil suction hose is sleeved on the rotating wheels and is in contact with the liquid surface of the mine water pre-sedimentation tank. A motor is installed on the fixed frame and connected to the rotating wheels.

[0014] The output end of the motor is connected to the input end of the hydraulic cylinder.

[0015] Another technical solution adopted in this invention is an integrated treatment method for mine water sludge and floating oil, comprising the following steps: Step 1: Obtain relevant information about the pre-sedimentation tank; Step 2: Based on the relevant information of the pre-sedimentation tank, set up the sludge collection and discharge system and the floating oil treatment system, and connect the sludge collection and discharge system and the floating oil treatment system to the control system. Step 3: Remove the sludge from the bottom of the mine water pre-sedimentation tank through the sludge collection and discharge system, and clean the floating oil on the surface of the mine water pre-sedimentation tank through the oil spill treatment system.

[0016] Another feature of the technical solution of this invention is that: Step 3 specifically includes the following steps: the motor is started through the control system, the output of the motor transmits power to the rotating wheel and hydraulic cylinder, the rotating wheel drives the oil suction hose to rotate, the oil suction hose absorbs the floating oil on the surface of the mine water pre-sedimentation tank, and the oil scraper cleans the floating oil on the oil suction hose and collects it in the oil collection tank. The hydraulic cylinder drives the triangular boom to rotate via the piston rod, and the triangular boom drives the slide plate to reciprocate via the horizontal push rod. Several wedge-shaped scrapers at the bottom of the slide plate collect the sludge at the bottom of the mine water pre-sedimentation tank into the annular air-mixing sludge hopper.

[0030] Combination Figure 4 As shown, the tubular oil separator 7 is installed above the mine water pre-sedimentation tank. The tubular oil separator 7 includes a fixed frame, which is movably connected to the side rail of the tank. Rotating wheels 20 are respectively installed at both ends of the fixed frame near the mine water pre-sedimentation tank. An oil scraper 22 and an oil collection trough 23 are installed between the rotating wheels 20, and the oil scraper 22 and the oil collection trough 23 are fitted together. An oil suction hose 21 is installed between the oil scraper 22 and the oil collection trough 23, and the oil suction hose 21 is sleeved on the rotating wheels 20, with the oil suction hose 21 in contact with the liquid surface of the mine water pre-sedimentation tank.

[0031] Example 5 This embodiment proposes an integrated treatment method for mine water sludge and floating oil, including the following steps: Step 1: Obtain relevant information about the pre-sedimentation tank; Step 2: Based on the relevant information of the pre-sedimentation tank, set up sludge collection and discharge system 1 and oil spill treatment system 2, and connect sludge collection and discharge system 1 and oil spill treatment system 2 to control system 3. Step 3: Remove the sludge from the bottom of the mine water pre-sedimentation tank through the sludge collection and discharge system 1, and clean the floating oil on the surface of the mine water pre-sedimentation tank through the oil treatment system 2.

[0032] Example 6 This embodiment proposes an integrated treatment method for mine water sludge and floating oil, including the following steps: Step 1: Obtain relevant information about the pre-sedimentation tank; Step 2: Based on the relevant information of the pre-sedimentation tank, set up sludge collection and discharge system 1 and oil spill treatment system 2, and connect sludge collection and discharge system 1 and oil spill treatment system 2 to control system 3. Step 3: Remove the sludge from the bottom of the mine water pre-sedimentation tank through sludge collection and discharge system 1, and clean the floating oil on the surface of the mine water pre-sedimentation tank through oil treatment system 2. The motor 19 is started by the control system 3. The output of the motor 19 transmits power to the rotating wheel 20 and the hydraulic cylinder 8. The rotating wheel 20 drives the oil suction hose 21 to rotate. The oil suction hose 21 absorbs the floating oil on the surface of the mine water pre-sedimentation tank. After the oil scraper 22 cleans the floating oil on the oil suction hose 21, it is collected in the oil collection tank 23. The hydraulic cylinder 8 drives the triangular boom 10 to rotate through the piston rod 9. The triangular boom 10 drives the slide plate 18 to reciprocate through the horizontal push rod 14. Several wedge-shaped scrapers 13 set at the bottom of the slide plate 18 collect the sludge at the bottom of the mine water pre-sedimentation tank into the annular air-mixing sludge hopper 5. The wear-resistant slurry pump 6 discharges the sludge from the annular air-mixing sludge hopper 5 through the sludge discharge pipe 25.

[0033] In this invention, the annular air-mixing sludge hopper 5 is set at the bottom of the pool at the inlet end as a storage place for the sludge scraped by the submersible reciprocating sludge scraper 4. The wear-resistant slurry pump 6 discharges the sludge from the annular air-mixing sludge hopper 5 through the sludge discharge pipe 25, realizing the effective transportation of sludge. The tubular oil remover 7 is set above the pool body to adsorb floating oil. The air outlet holes on the annular air-mixing sludge hopper 5 are evenly distributed on the annular pipe of the hopper. Compressed air enters the annular air-mixing sludge hopper 5 through the pipe to make the sludge and air slightly agitate, effectively relieving the sludge from hardening in the hopper and helping to improve the sludge treatment efficiency. The wedge-shaped scraper 13 is set parallel to the horizontal push rod 14 for efficiently scraping the sludge from the bottom of the pool. In the tubular oil separator 7, the fixed frame is located above the pool body and serves as the load-bearing component for the entire device. The fixed frame is connected to the pool side rail and moves parallel or vertically along the pool side. The rim of the rotating wheel 20 is inlaid with wear-resistant ceramics on both sides. The motor 19 slowly rotates to drive the rotating wheel 20 to rotate the oil suction hose 21 connected to it. The oil suction hose 21 floats on the pool surface in a meandering manner. During rotation, the fixed frame of the rotating wheel 20 is equipped with an adjustable clamping device that allows the oil suction hose 21 to fit into the roller. The oil scraper 22 is located above the fixed frame and scrapes off the oil from the surface of the oil suction hose 21 that is covered with oil and collects it into the oil collection tank 23. The cleaned oil suction hose 21 is then rotated back into the pool by the motor 19 to continue absorbing floating oil.

[0034] The motor 19 in the tubular oil separator 7 is connected to the hydraulic cylinder 8 in the submersible reciprocating sludge scraper 4 via an electrical drive; the control system 3 is electrically connected to the annular air-mixing sludge hopper 5, and the control system 3 is electrically connected to the motor 19 in the floating oil treatment system 2.

[0035] In the integrated treatment method for mine water sludge and floating oil of this invention, when the driving hydraulic cylinder 8 of the submersible reciprocating sludge scraper 4 drives the piston rod 9 to move back and forth, the piston rod 9 pushes the triangular arm 10 to rotate around the hinge point. The triangular arm 10 drives the horizontal push rod 14, and the horizontal push rod 14 drives several wedge-shaped scrapers 13 to move together to scrape sludge at the bottom of the pool. During the sludge scraping process, the sludge scraping module of the submersible reciprocating sludge scraper 4 will continuously reciprocate to ensure that the sludge at the bottom of the pool is thoroughly scraped. The return speed of the sludge scraping system is about 2-3 times the forward speed. The movement trajectory and speed of the sludge scraper can be adjusted according to actual needs to adapt to different pool sizes and sludge distribution.

[0036] As the slide plate 18 slides along the horizontal push rod 14, the wedge-shaped scraper 13 moves accordingly, scraping up the sludge and collecting it into the annular air-mixing sludge hopper 5. When compressed air enters the annular air-mixing sludge hopper 5 through the compressed air pipe 24, it is ejected from the air outlet, forming bubbles that micro-stir the surrounding sludge. The wear-resistant slurry pump 6 uses frequency conversion control to discharge sludge from the hopper system, reducing the failure rate of the sludge transportation process and effectively ensuring the long-term stable operation of the pre-sedimentation tank. When the tubular oil separator 7 above the tank starts working, the oil suction hose 21 adsorbs floating oil on the water surface. The special material of the oil suction hose 21 enables it to have an affinity for oil molecules, effectively adsorbing floating oil on the water surface. The tubular oil separator 7 can move parallel or vertically along the pool side rails laid along the pool side, thereby achieving oil removal operations in different areas of the pool, improving oil removal efficiency and effect, and ensuring that the oil pollution on the entire pool surface can be effectively treated. After the oil suction hose 21 absorbs the floating oil, it is driven back to the top of the fixed frame by the rotating wheel 20. The oil scraper 22 scrapes the oil off the hose and collects it into the oil collection tank 23, ensuring efficient oil collection while avoiding damage to the hose. The collected floating oil can be transported through pipelines to an oil-water separator for oil-water separation. The separated oil is mainly composed of sludge with low water content, which is sent to the coal yard to effectively utilize the calorific value of the sludge and is finally sent to the boiler for incineration. This cycle achieves automated, continuous, and recyclable integrated treatment of sludge and floating oil. This invention ensures effective separation of sludge and floating oil through the coordinated operation of a high-efficiency sludge collection and discharge system 1, a floating oil treatment system 2, and a control system 3. The sludge scraper moves along the bottom of the tank while rotating, achieving automatic sludge collection. The cooperation between the sludge scraper and the oil removal components can promptly separate and discharge the collected sludge and adsorbed floating oil, achieving continuous treatment of sludge and floating oil and recycling of the device through cyclical operation. This not only improves the efficiency of mine water treatment, but also reduces the risk of blockage in subsequent treatment equipment due to the accumulation of sludge and floating oil.
