Description

Technical Field

[0001] This invention relates to the field of underground coal mine wastewater treatment technology, and in particular to a wastewater treatment control device. Background Technology

[0002] Wastewater treatment in coal mines is a crucial step in ensuring safe production and achieving water resource recycling. Currently, the conventional method involves pumping underground wastewater to a surface mine wastewater treatment plant for centralized treatment, with some discharged and some reused. However, this method has the following prominent problems:

[0003] 1. Underground sewage needs to be pumped to the surface, which consumes a lot of electricity and the pipelines are severely worn, resulting in high maintenance costs;

[0004] 2. Traditional underground water tanks only serve the purpose of collection and preliminary sedimentation, and their ability to classify and purify is insufficient, leading to rapid deposition of coal slime. Subsequent manual dredging operations are intensive, inefficient, and pose high safety risks.

[0005] 3. The surface treatment station undertakes the primary and intermediate purification tasks that could have been completed underground. The treatment load is heavy, and in order to cope with the complex fluctuations of underground sewage, the amount of reagents added is huge, resulting in high operating costs. Summary of the Invention

[0006] This invention provides a wastewater treatment control device to solve the problems of high cost of underground wastewater lifting and difficulty in cleaning water sumps. This device can achieve multi-stage coordinated and progressive purification of coal slurry water within the limited space underground, thereby eliminating dependence on surface treatment stations and fundamentally solving the problem of water sump accumulation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wastewater treatment control device includes a vibrating screen mechanism and a water tank. The vibrating screen mechanism includes a screening section and a vibrating section, and the screening section is supported by a support frame.

[0009] A rotating mechanism is provided between the vibrating screen mechanism and the water tank. The rotating mechanism is driven by a linear drive mechanism, covers the water tank, and is used to clean the inner wall of the water tank.

[0010] The rotating mechanism includes a partition, a drive unit, and a rotating assembly. The partition divides the pool into a murky water zone and a clear water zone. The water in the clear water zone is used underground, while the sludge at the bottom of the murky water zone is discharged externally.

[0011] In some embodiments, the partition includes a support plate, the support plate having a first rotating groove and a second rotating groove inside, a rotating gear being rotatably connected inside the second rotating groove, the bottom of the rotating gear penetrating the support plate and having a partition plate thereon, and a rotating gear driving multiple rotating gears and partition plates to rotate, thereby controlling the isolation and connection between the muddy water zone and the clear water zone.

[0012] In some embodiments, the top of the rotating gear is provided with a first adsorption block, and the bottom of the second drive gear is fixedly connected to an electromagnetic block via a connecting shaft. The electromagnetic block is de-energized to control the connection between the electromagnetic block and the rotating gear.

[0013] In some embodiments, a telescopic limiting structure is provided between the connecting shaft and the electromagnetic block to reduce the friction between the connecting shaft and the electromagnetic block after the electromagnetic block is de-energized.

[0014] In some embodiments, the rotating assembly includes a rotating column, a toothed ring at the top of the rotating column, a rotating shaft rotatably connected to the top of the toothed ring, and the top of the rotating shaft being fixedly connected to a support plate via a connecting plate.

[0015] The bottom of the rotating column is equipped with a stirring blade, and the end of the stirring blade away from the rotating column is equipped with a scraper to clean the inner wall of the water tank.

[0016] In some embodiments, the rotating assembly is provided in two sets, with the two sets of rotating assemblies located on both sides of the partition, for cleaning the inner walls of the muddy water area and the clear water area pool; the second drive gear is connected to the gear ring drive via a synchronous belt.

[0017] In some embodiments, the partition plate is provided with multiple partition plates, and multiple steering gears are respectively provided between the multiple rotating gears. The steering gears are used to keep the multiple partition plates rotating in the same direction.

[0018] In some embodiments, an adapter is provided above the rotating column near the bottom of the vibrating screen mechanism. A collection cover is rotatably connected to the top of the adapter. An upper scraper is provided on the top of the collection cover for scraping and cleaning the bottom end of the transmission belt of the screening section. A toothed ring is provided circumferentially on the adapter and is connected to the synchronous belt drive. A first electromagnet and a second electromagnet are provided inside the adapter. The top of the rotating column and the bottom of the connecting column are provided as second adsorption blocks for controlling the adapter to disengage from the collection cover and the rotating column, respectively.

[0019] In some embodiments, the bottom of the rotating column is provided with a lower scraper plate, which is used to clean the bottom wall of the pool.

[0020] In some embodiments, a drainage assembly is provided on the rotating column near the top of the vibrating screen mechanism. The drainage assembly includes a water tank, and a water spray pipe is provided on the top of the water tank. The end of the water spray pipe away from the water tank extends to the clear water area for guiding water into the clear water area.

[0021] The rotating column is designed as a hollow structure, and an electric push rod is provided at the top of the inner cavity of the rotating column. The telescopic end of the electric push rod is connected to a push plate. The diameter of the push plate is smaller than that of the barrier cover. A barrier cover is provided between the water tank and the push plate to prevent pollutants from entering the water tank. The gap between the water tank and the push plate is used for the folding of the barrier cover when the push plate is raised or lowered.

[0022] Compared with the prior art, the present invention provides a wastewater treatment control device with the following beneficial effects.

[0023] 1. This invention combines vibrating screening with dynamic zoned sedimentation in a water tank to form a multi-stage treatment process. It can directly complete the entire process of coal slurry water from coarse particle separation to fine particle sedimentation and clarification underground. The treated clean water can be directly used for production processes such as watering, dust suppression, and fire fighting, eliminating the high electricity costs of raising large amounts of sewage to the surface. At the same time, it reduces the load and chemical consumption of the surface sewage treatment station, thereby reducing the overall operating cost of the mine from the source.

[0024] 2. This invention uses a rotatable and adjustable partition plate to achieve dynamic isolation or connection between the clear water zone and the turbid water zone. As a secondary treatment unit of this process, during normal operation, the zoned sedimentation ensures that the water quality in the clear water zone meets the standards. When the water flow suddenly increases, the sedimentation zone can be rapidly expanded to effectively prevent sewage overflow. The system has strong shock resistance and more stable effluent quality.

[0025] 3. The present invention integrates stirring blades, scrapers and lower scraping plates in the rotating component, which can automatically prevent sludge from accumulating and hardening at the bottom and walls of the pool. At the same time, it can scrape and clean the vibrating screen to prevent the screen holes from clogging. It fundamentally reduces the heavy labor of manual sludge removal in traditional water tanks, improves the working environment and increases production efficiency.

[0026] 4. This invention, through the movable drainage component and the detection of turbidity sensor, can extract water with lower turbidity from the upper layer of the turbid water area to supplement the clear water area. Without polluting the clear water area, it significantly improves the recycling rate of underground sewage, ensures stable water supply, and further reduces the amount of fresh water taken out.

[0053] The bottom of the rotating column 3031 is provided with a lower scraper 3037, which is used to clean the bottom wall of the water tank 2. An elastic scraper strip is provided at the bottom of the lower scraper 3037 to adapt to the bottom wall of the water tank 2 and maintain continuous contact with the bottom wall of the water tank 2. The lower scraper 3037 is located on the rotating column 3031 near the bottom of the vibrating screen mechanism 1.

[0054] A drainage assembly 5 is provided on the rotating column 3031 near the top of the vibrating screen mechanism 1.

[0055] The rotating column 3031 is designed as a hollow structure. An electric push rod 503 is provided at the top of the inner cavity of the rotating column 3031. The telescopic end of the electric push rod 503 is fixedly connected to the push plate 502 through the connecting rib 5031. The diameter of the push plate 502 is smaller than that of the barrier cover 504. A barrier cover 504 is provided between the water tank 501 and the push plate 502. The barrier cover 504 has a ring structure and is used to block pollutants from entering the water tank 501. The gap between the water tank 501 and the push plate 502 is used for the folding of the barrier cover 504 when the push plate 502 is raised or lowered.

[0056] In this invention, the coal slurry water after uniform mixing is transported to the top of the screening section 101 through a slurry pump and a distribution box for solid-liquid separation. Driven by the vibrating section 102, the screening section 101 vibrates continuously. Through vibration and natural gravity, the coal slurry permeates through the screening section 101 to the water pool 2. The coal particles continue to move along the screening section 101 to the bottom. A collection component for receiving coal particles is provided at the bottom of the screening section 101. After the coal particles move to the bottom of the screening section 101, they are discharged into the collection component. The collection component can be a belt conveyor, which transports the coal particles out of the mine.

[0057] Initially, the multiple partition plates 3011 are flush, dividing the interior of the water tank 2 into a clear water zone and a turbid water zone. Specifically, the area of ​​the water tank 2 near the bottom of the vibrating screen mechanism 1 is the clear water zone, and the area of ​​the water tank 2 near the top of the vibrating screen mechanism 1 is the turbid water zone. The bottom of the water tank 2 slopes downwards from the clear water zone to the turbid water zone. The coal particles with the highest concentration and largest particle size in the coal slurry water conveyed to the top of the screening section 101 preferentially fall into the turbid water zone under the vibration of the screening section 101 and settle rapidly there. When the coal slurry water moves to the bottom of the screening section 101, at this time... The amount of coal slurry water that can fall is less, and the turbidity of the coal slurry water in the clear water zone is even lower. A drainage pipe is installed in pool 2 corresponding to the clear water zone to promptly discharge the low-turbidity coal slurry water from pool 2 for use, such as dust suppression in underground production, fire fighting in engineering projects, and drilling water. By directly utilizing the lower-turbidity coal slurry water underground, groundwater extraction can be reduced or even eliminated. On-site treatment and reuse of the coal slurry water underground avoids the huge electricity costs of raising all the coal slurry water to the surface, and also reduces the treatment load and chemical consumption of the surface wastewater treatment plant, thus significantly saving production costs. A sewage pipe is installed in pool 2 corresponding to the turbid water zone to centrally discharge the sludge accumulated at the bottom of the turbid water zone.

[0058] Furthermore, to prevent sludge from accumulating and hardening at the bottom of pool 2, a rotating motor 3026, located on top of support plate 3015, is activated. At this time, the electromagnetic block 3023 remains de-energized, separating the murky and clear water zones. The rotating motor 3026 drives the second driving gear 3022 via the first driving gear 3021. The second driving gear 3022 then drives the rotating column 3031 and stirring blade 3035 via the synchronous belt 3025. The stirring blade 3035 moves the sludge at the bottom of pool 2, preventing it from accumulating and hardening. During the rotation of the rotating column 3031, the scraper 3036 follows the rotating column 3031, rotating around the column 3031 as its center, scraping away the sludge from the inner wall of pool 2 and removing accumulated pollutants. Driven by the linear drive mechanism 4, the rotating mechanism 3 moves horizontally within pool 2, increasing its working range.

[0059] When the underground water inflow is large and the coal slurry concentration suddenly increases, to prevent the coal slurry water from overflowing from the murky water zone or entering the clear water zone, the electromagnetic block 3023 is energized to generate magnetic force. The electromagnetic block 3023 attracts the first adsorption block 3013, causing the second drive gear 3022 to rotate coaxially with the first adsorption block 3013. The rotating motor 3026 is started, driving the second drive gear 3022 and the partition plate 3011 to rotate. The rotating gears 3012 on the top of the multiple partition plates 3011 mesh with each other, causing the multiple partition plates 3011 to rotate synchronously, directly connecting the clear water zone and the murky water zone. The clear water zone, as a supplement to the volume space of the murky water zone, is designed to cope with the sudden influx of a large amount of coal slurry water.

[0060] However, when the clear water zone and the turbid water zone are connected, the sludge that should have settled in the turbid water zone will also settle in the clear water zone, making it difficult for the coal slurry water in the clear water zone to meet the underground water requirements. Therefore, after the coal slurry water is completely transported into the water tank 2, the angles of the multiple partition plates 3011 remain unchanged. Depending on the usage requirements, an electromagnetic pin can be installed on the top of one partition plate 3011, and a locking groove is opened at the bottom of the support plate 3015 corresponding to the position of the partition plate 3011. After the rotating motor 3026 controls the partition plate 3011 to rotate to a specified angle through the first drive gear 3021 and the second drive gear 3022, the electromagnetic pin is de-energized, causing the locking end of the electromagnetic pin to extend outward and be positioned in the locking groove of the support plate 3015, thus stably maintaining the tilt angle of the partition plate 3011. Then, the power supply to the electromagnetic block 3023 is disconnected, and at this time, the rotating motor 3026 drives the second drive gear... When wheel 3022 rotates, partition plate 3011 remains stationary and does not impede the movement of second drive gear 3022. Second drive gear 3022 drives two rotating columns 3031 to rotate synchronously via synchronous belt 3025. Two sets of stirring blades 3035 stir the coal slurry in the turbid water zone and the clear water zone respectively. At this time, with the help of the inclined bottom wall of the pool 2, the coal slurry is disturbed during the stirring process of the stirring blades 3035 and moves towards the turbid water zone under the influence of natural gravity. The sludge in the clear water zone is transferred to the turbid water zone through the gap of partition plate 3011. During the rotation of rotating column 3031 in the clear water zone, the lower scraper plate 3037 at the bottom of the rotating column 3031 scrapes the bottom wall of the pool 2, accelerating the separation speed of sludge in the clear water zone from the bottom wall of the pool 2 and improving the cleaning effect of sludge on the bottom wall of the pool 2, thereby accelerating the transfer speed of sludge from the clear water zone to the turbid water zone.

[0061] A first turbidity sensor can be installed inside the clear water zone to detect the concentration of coal slurry water in the clear water zone. When the concentration is lower than the preset turbidity value, the electromagnetic pin on the partition plate 3011 is energized, causing the locking end of the electromagnetic pin to disengage from the locking groove of the support plate 3015. The electromagnetic block 3023 is then energized again, causing the second drive gear 3022 to rotate coaxially with the first adsorption block 3013. Driven by the rotating motor 3026, the multiple partition plates 3011 are brought back into alignment, and the multiple partition plates 3011 separate the clear water zone and the turbid water zone again, restoring the clear water zone to a low turbidity level to meet the underground water requirements.

[0062] During use, when the low-turbidity coal slurry water in the clear water zone is used as a water source, the coal slurry water resources in the clear water zone cannot meet the demand. After sedimentation and sludge discharge, the coal slurry water in the turbid water zone will form a stratification phenomenon. The water in the upper layer of the turbid water zone has a turbidity close to that of the water in the clear water zone and can also be used as a water source. However, directly controlling the rotation of the partition plate 3011 to connect the clear water zone and the turbid water zone will cause the clear water zone to be contaminated by sludge again, resulting in the need to thoroughly clean both the clear water zone and the turbid water zone when cleaning the water pool 2 later. This is not conducive to the stable utilization of low-turbidity coal slurry water resources.

[0063] To address this, a water level sensor can be installed in the clear water zone to detect the water level. When the coal slurry water in the clear water zone falls below a preset height, water replenishment is initiated. This involves transferring the lower turbidity water from the upper layer of the turbid water zone to the clear water zone via the drainage component 5. Specifically, the threaded shaft of the linear drive motor 403 engages with the threaded slider 402, causing the separator 301 to move towards the turbid water zone, gradually reducing its volume while simultaneously increasing the water level. This ensures that the drainage component 5 remains submerged in the upper layer of water within the turbid water zone. Inside, the telescopic end of the electric push rod 503 drives the push plate 502 to move upward through the connecting rib 5031, thereby pushing the push plate 502 upward to connect with the water tank 501. As the push plate 502 continues to move upward, it pushes the water in the water tank 501 into the clear water zone through the spray pipe 5011. With the repeated up and down movement of the electric push rod 503 and the continuous driving of the linear drive mechanism 4 to drive the partition 301 to reduce the volume of the turbid water zone and increase the water level in the turbid water zone, the push plate 502 continuously cooperates with the water tank 501 to transfer the upper layer of water in the turbid water zone to the clear water zone, maintaining the water supply demand in the well.

[0064] According to usage requirements, a second turbidity sensor is installed in the water tank 501. The second turbidity sensor in the water tank 501 detects the turbidity of the water in the water tank 501. When the turbidity of the water in the water tank 501 is lower than the preset value of the second turbidity sensor, the transfer of the upper layer of water in the turbid water zone to the clear water zone is maintained. When the second turbidity sensor detects that the water in the water tank 501 is higher than the preset value, the transfer of the upper layer of water in the turbid water zone to the clear water zone is stopped. When the water level in the clear water zone is lower than the drain pipe, the supply of well water using the water in the water pool 2 as the water source is interrupted.

[0065] A collection cover 305 is provided above the rotating column 3031 near the bottom of the vibrating screen mechanism 1. An upper scraper 3052 is provided on the top of the collection cover 305, and an elastic scraper strip is provided on the top of the upper scraper 3052.

[0066] In this embodiment, the traditional screening method using a sieve plate as the screening section 101 is improved by using a circulating transmission belt to vibrate and separate coal particles and water in the coal slurry. Through the cyclic rotation of the transmission belt, the upward-facing transmission belt is changed to a downward-facing one. The vibration effect when the vibration section 102 is started improves the separation efficiency of particles such as clay, coal powder, or salt powder when the transmission belt is facing downward, thereby keeping the sieve holes on the transmission belt unobstructed, allowing water and fine particles to pass through smoothly, and maintaining the processing capacity of the transmission belt.

[0067] To reduce the amount of fine particles entering the clean water zone during this stage, the linear drive mechanism 4 controls the rotating mechanism 3 to move to the bottom of the vibrating screen mechanism 1 during the coal slurry water treatment stage. At this time, the collection cover 305 covers the bottom of the screening section 101, and the elastic scraping strip on the top of the upper scraping plate 3052 abuts against the transmission belt of the screening section 101. Then, the rotating motor 3026 is started, which drives the rotating column 3031 and the upper scraping plate 3052 on its top to rotate. During the cyclic rotation of the transmission belt, the elastic scraping strip on the top of the upper scraping plate 3052 continuously scrapes and cleans the downward-facing transmission belt surface, and the collection cover 305 receives the particles cleaned off the transmission belt.

[0068] According to the usage requirements, an adapter 304 can be provided above the rotating column 3031 near the bottom of the vibrating screen mechanism 1. The rotating column 3031 is connected to the collection cover 305 through the adapter 304. Specifically, a first electromagnet 3041 and a second electromagnet 3042 are provided inside the adapter 304. The top of the rotating column 3031 is rotatably connected to the inside of the adapter 304. The collection cover 305 is rotatably connected to the top of the adapter 304. A connecting column 3051 is provided at the bottom of the collection cover 305. The bottom end of the connecting column 3051 is rotatably connected to the inside of the adapter 304.

[0069] The top of the rotating column 3031 corresponds to the first electromagnet 3041, and the bottom of the connecting column 3051 corresponds to the second electromagnet 3042. The top of the rotating column 3031 and the bottom of the connecting column 3051 are set as second adsorption blocks, which are used to magnetically connect with the first electromagnet 3041 and the second electromagnet 3042 respectively.

[0070] The rotating column 3031 and the connecting column 3051 are rotatably supported by the support plate 3015, maintaining their horizontal positions. The toothed ring 3032 is located circumferentially on the adapter 304 and is connected to the synchronous belt 3025 for transmission. In use, after the first electromagnet 3041 and the second electromagnet 3042 are energized, they magnetically attract and fix the top end of the rotating column 3031 and the bottom end of the connecting column 3051, respectively. At this time, the collecting cover 305 and... The rotating column 3031 rotates synchronously and coaxially with the adapter 304. During the coal slurry water treatment stage in the screening section 101, the first electromagnet 3041 is de-energized while the second electromagnet 3042 remains energized. This ensures that when the adapter 304 rotates, it only drives the collection cover 305 and the upper scraper 3052 to rotate. By installing a gearbox on the rotating motor 3026, the rotation speed of the upper scraper 3052 can be controlled, allowing the elastic scraping strips on the upper scraper 3052 to scrape the bottom of the transmission belt more quickly and repeatedly, thereby improving the cleaning efficiency of the transmission belt.
