Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting and wastewater treatment technology, specifically a device to prevent daily watering for dust suppression on sunny days from overflowing into rivers. Background Technology

[0002] Air quality issues have gradually attracted public attention. High concentrations of dust are often found in sand and gravel processing plants, timber processing plants, and mines. Meanwhile, the large number of vehicles on the roads frequently generates dust, resulting in large amounts of dust floating in the air. This not only pollutes the air but can also harm human health if inhaled in excess. To improve air quality and protect human health, water spraying dust suppression devices have been developed to suppress dust in the air and treat the wastewater from the dust suppression process.

[0003] A Chinese patent with authorization announcement number CN112939259B discloses an open-pit coal mine wastewater treatment device comprising a guide frame, guide slip ring, elastic rope, connecting ring, upper baffle, outlet pipe, connecting ear, hydraulic rod, fixing ear, discharge pipe, settling tank, lower baffle, connecting shaft, hinge shaft, inlet pipe, wastewater tank body, transmission gear, drive box, chain, and flow-blocking teeth. Multiple lower baffles are equidistantly positioned on one side at the bottom of the wastewater tank body. The connecting shaft is positioned on one side of the lower baffle, with both ends of the connecting shaft positioned on the side walls of the wastewater tank body. The drive box is positioned on the outer wall of the wastewater tank body. The transmission gear is sleeved on the connecting shaft and located inside the drive box. Multiple transmission gears are connected by a chain. This invention uses a stepper motor to drive the lower baffle to reciprocate, and in conjunction with the extension and retraction of the hydraulic rod, causes the upper and lower baffles to swing left and right while changing their angle. This effectively shakes off the sludge adhering to the upper and lower baffles during settling, preventing sludge adhesion in the wastewater treatment device.

[0004] However, the coal mine wastewater treatment equipment has the following defects in actual use:

[0005] 1. Existing coal mine wastewater treatment equipment requires adsorption of particulate impurities (dust particles) in the wastewater when treating wastewater generated from coal mine dust suppression. However, in actual coal mine dust treatment, wastewater is typically transported to a collection tank via pipelines laid within the mine, and then transferred to the wastewater treatment equipment for further treatment. During this transfer, other impurities from the coal mine (such as plastics and fibers) are also transported into the wastewater treatment equipment, affecting the effectiveness of treating dust and other impurities in the wastewater.

[0006] 2. Currently, open-pit coal mines typically use coal mine water trucks to extract, store, and spray water from rainwater collection ponds when suppressing dust in the air. During this process, water may overflow into the coal yard and flow into the rainwater collection ponds. If not handled carefully, this water could flow into rivers, causing misunderstandings with environmental protection departments and resulting in economic and reputational losses for the company. Summary of the Invention

[0045] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0046] 1. In devices designed to prevent daily dust suppression spraying on sunny days from overflowing into rivers, wastewater generated during dust suppression operations can be treated through multi-stage treatment using screening grids and activated carbon adsorption balls to separate and adsorb particulate impurities (dust, coal slag, etc.) in the wastewater, ensuring that the discharged wastewater meets environmental emission standards. Simultaneously, the screening grids, which separate and screen other impurities (plastics, threads, etc.) in the wastewater, can be moved up and down by the force of agitation and stirring of the activated carbon adsorption balls. This ensures that after some of the wastewater has been screened and separated, the screened and separated impurities can be moved by the suction force generated by an air pump to the storage tank for storage, reducing the problem of excessive impurities (plastics, threads, etc.) clogging the internal grid holes of the screening grids and ensuring the effectiveness of screening and separating impurities in the wastewater.

[0047] 2. In the device for preventing daily dust suppression water from overflowing into rivers during sunny days, the activated carbon adsorption balls are stirred to adsorb impurities (dust and coal slag, etc.) in the wastewater. The activated carbon adsorption balls are moved by the rotational force of multiple stirring blades and stirring rods rotating in opposite directions, generating two vortices in opposite directions. This ensures that the activated carbon adsorption balls can fully contact the impurities (dust and coal slag, etc.) in the wastewater, improving the adsorption effect and efficiency of the activated carbon adsorption balls on the impurities in the wastewater. This ensures that the treatment of impurities (dust and coal slag, etc.) in the wastewater can be achieved quickly in a short period of time.

[0048] 3. In devices designed to prevent daily dust suppression spraying on sunny days from overflowing into rivers, rainwater collection ponds serve two main purposes. First, they collect rainwater from rainy days, which can then be directly used for dust suppression in coal mines, reducing water waste. Second, the rainwater collection ponds also collect wastewater from dust suppression. After dust suppression in the coal mine, the wastewater can be automatically treated in a wastewater treatment tank, preventing direct discharge and mitigating various negative impacts, making it more environmentally friendly and sustainable.

[0049] 4. In devices designed to prevent daily dust suppression spraying on sunny days from overflowing into rivers, when the rainwater collection tank collects and stores rainwater or wastewater (coal mine dust suppression), the water level of the rainwater or wastewater collected inside the rainwater collection tank can cause foam blocks and floats on the water surface to move upwards. The position of the foam blocks and floats can be detected by a liquid level detection sensor, achieving highly accurate rainwater or wastewater level detection and reducing the problem of rainwater or wastewater not being discharged and treated in a timely manner.

[0073] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0074] Please see Figures 1-12 A device for preventing daily dust suppression spraying on sunny days from overflowing into rivers includes a rainwater collection tank 10 and a wastewater treatment tank 20. The rainwater collection tank 10 has a rainwater sensing system 30 extending outwards inside. Water outlet pipes 100 connect to the left and right sides of the rainwater collection tank 10. A water pump 300 is connected to the bottom of one of the water outlet pipes 100. The outlet of the water pump 300 is connected to the wastewater treatment tank 20 via a conveying pipe 3001. The wastewater treatment tank 20 is located inside an industrial water treatment workshop. An integrated wastewater multi-treatment mechanism 40 extending outwards is installed inside the wastewater treatment tank 20. Several activated carbon adsorption balls are installed at the bottom of the wastewater treatment tank 20. The integrated wastewater multi-treatment mechanism 40... The system includes a dual stirring assembly 50, which is installed at the bottom of the wastewater treatment tank 20 and extends to the bottom of the wastewater treatment tank 20. A lifting compensation assembly 60 is connected to the top of the dual stirring assembly 50 and is located at the center of the wastewater treatment tank 20. A lifting screening assembly 70 is installed inside the wastewater treatment tank 20 and connected to the top of the lifting compensation assembly 60. A waste extraction assembly 80 is installed above the lifting screening assembly 70 and is installed at the top of the wastewater treatment tank 20. The waste extraction assembly 80 extends to one side of the top of the wastewater treatment tank 20.

[0075] In this invention, the wastewater treatment tank 20 is provided with a debris screening chamber 201 and an impurity adsorption chamber 202. The debris screening chamber 201 is located above the impurity adsorption chamber 202 and is connected to the conveying pipe 3001. The debris screening chamber 201 is provided with a lifting screening component 70, and a waste extraction component 80 extending to the outside is installed on the inner top of the debris screening chamber 201. The debris screening chamber 201 and the impurity adsorption chamber 202 are connected by a guide pipe 203. The impurity adsorption chamber 202 is provided with a number of activated carbon adsorption balls and a double stirring component 50. The guide pipe 203 is provided with a lifting compensation component 60 on its side.

[0076] The working principle described above is as follows: When treating the dust suppression wastewater collected inside the rainwater collection tank 10, the wastewater is transported to the interior of the wastewater treatment tank 20 via the water pump 300 and the conveying pipe 3001. Through the internal structure of the lifting and screening component 70, other impurities (such as plastics and threads) in the wastewater are separated. Simultaneously, the dual stirring component 50 is automatically activated to continuously agitate and stir the wastewater and activated carbon adsorption balls after the other impurities have been screened. This ensures that particulate impurities in the wastewater can fully contact and be adsorbed by the activated carbon adsorption balls, achieving automatic wastewater treatment. While the dual stirring component 50 is operating, the lifting compensation component 60 can controllably drive the lifting and screening component 70 to move the other impurities (such as plastics and threads) separated by the lifting and screening component 70 to the area below the waste extraction component 80, where the waste extraction component 80 extracts and recovers the remaining impurities (such as plastics and threads).

[0077] In this invention, the rainwater sensing system 30 is designed so that it activates during rainy weather, disconnecting the automatic drainage circuit of the outlet pipe 100, thus achieving intelligent recycling of daily wastewater from the industrial park. The rainwater collection tank 10 returns to normal operation during rainy weather. On sunny days, wastewater from coal mine dust suppression treatment is transported through the rainwater collection tank 10 to the wastewater treatment tank 20, where it undergoes automatic treatment. This system offers advantages such as being environmentally friendly, preventing wastewater discharge, and conserving water resources.

[0078] For details, please refer to the following: Figure 3 , Figure 4 and Figure 12The rainwater sensing system 30 includes a rainwater sensing module 301, which is installed on one side of the top of the rainwater collection tank 10. The rainwater sensing module 301 is electrically connected to the power distribution device and the water pump 300. The side mounting frame 302 is installed on the left and right sides inside the rainwater collection tank 10. A liquid level detection sensor 3021 is installed inside one side mounting frame 302, and a foam block 303 is slidably connected inside the other side mounting frame 302. A float ball 304 is connected to the side of the foam block 303 by a wire. The float ball 304 is located inside the rainwater collection tank 10.

[0079] In this embodiment, the rainwater sensing module 301 and the control valve 3011 are electrically connected. There are two control valves 3011, which are respectively installed on the outside of the two water outlet pipes 100. The rainwater sensing module 301 and the integrated wastewater multi-treatment mechanism 40 are electrically connected.

[0080] In the device of the present invention for preventing daily watering and dust suppression on sunny days from overflowing into rivers, the rainwater sensing module 301 is designed to detect whether the weather is raining and automatically control the control valve 3011 to separately control the drainage operation of the two outlet pipes 100. When the rainwater collection tank 10 starts collecting rainwater or wastewater, the foam block 303 and the float ball 304 can float under the action of water, and the position and height of the rainwater or wastewater are detected by the liquid level detection sensor 3021.

[0081] For details, please refer to the following: Figure 7 and Figure 8 The dual stirring assembly 50 includes a lower base 501, which is screwed to the center of the bottom of the wastewater treatment tank 20. A linear motor 502 is mounted on the bottom of the lower base 501, and the output end of the linear motor 502 is connected to a main shaft 503, which is rotatably connected to the bottom of the wastewater treatment tank 20. A drive belt 504 is connected to the outside of the main shaft 503 via a synchronous pulley key on its inner side. The drive belt 504 is movably mounted on the top of the lower base 501, and a vertical shaft 505 is connected to the inside of the drive belt 504 via a synchronous pulley key. A straight shaft 505 extends into the interior of the impurity adsorption chamber 202; there are two transmission gears 506, which are meshed and connected. Both transmission gears 506 are rotatably connected to the bottom of the wastewater treatment tank 20. One transmission gear 506 is connected to the main shaft 503. A concave bracket 507 is installed inside the other transmission gear 506. The concave bracket 507 extends into the interior of the wastewater treatment tank 20 and is rotatably connected to the interior of the impurity adsorption chamber 202. A vertical shaft 505 is installed through the interior of the concave bracket 507.

[0082] In this embodiment, a plurality of stirring rods 5071 are installed on the outer side of the concave support 507. The stirring rods 5071 are movably disposed inside the impurity adsorption chamber 202. A lifting compensation component 60 is connected to the top of the concave support 507. A stirring blade 5051 is installed on the outer side of the vertical shaft 505. The stirring blade 5051 is movably disposed inside the impurity adsorption chamber 202. The stirring blade 5051 is disposed on the side of the concave support 507.

[0083] In the above embodiments, when the concave support 507 and the vertical shaft 505 rotate (in opposite directions), they can respectively drive the multiple stirring rods 5071 and stirring blades 5051 connected to their sides to rotate, thereby driving the wastewater and activated carbon adsorption balls to perform stirring and mixing operations in opposite directions, improving the effect and efficiency of activated carbon adsorption balls in adsorbing particulate impurities in wastewater.

[0084] In the device of the present invention for preventing daily dust suppression water from overflowing into rivers during sunny days, when the activated carbon adsorption balls adsorb particulate impurities in the wastewater, the linear motor 502 is activated to operate, driving the main shaft 503 connected to the output end of the linear motor 502 to rotate. At this time, when the main shaft 503 rotates, it can drive the vertical shaft 505 connected to its outer side via the transmission belt 504 to rotate, and it can also drive the concave support 507 at its bottom, which is connected to the bottom via two transmission gears 506, to rotate, thereby realizing the stirring and mixing operation of wastewater and activated carbon adsorption balls.

[0085] For details, please refer to the following: Figure 9 The lifting compensation component 60 includes a lower connecting rod 601, which is installed on the top of the concave bracket 507 and passes through the impurity adsorption chamber 202. The lower connecting rod 601 is rotatably connected to the wastewater treatment tank 20. The lower connecting rod 601 has a lower groove 602 inside, and a connecting rod 603 extending to the outside is slidably connected inside the lower groove 602. The middle block 604 is installed at the center of the outside of the connecting rod 603. A lifting block 605 is movably connected to the outside of the middle block 604. Multiple lifting cylinders 606 are connected to the top of the lifting block 605 and are installed inside the wastewater treatment tank 20.

[0086] In this embodiment, the top of the connecting rod 603 extends into the interior of the upper groove 607, which is located at the bottom of the upper connecting rod 608. The top of the upper connecting rod 608 extends into the interior of the debris screening chamber 201, and the top of the upper connecting rod 608 is connected to the lifting screening assembly 70.

[0087] In the device for preventing daily dust suppression spraying on sunny days from overflowing into rivers, when it is necessary to process the impurities screened by the lifting and screening component 70, the lifting cylinder 606 can be activated to operate, driving the intermediate block 604 and connecting rod 603 connected to the output end of the lifting cylinder 606 to move up and down. At this time, when the bottom of the connecting rod 603 extends into the lower groove 602 inside the lower connecting rod 601, the rotation of the concave bracket 507 will drive the lower connecting rod 601 and the connecting rod 603 to rotate, and drive the upper connecting rod 608 connected to the connecting rod 603 to rotate. When the connecting rod 603 is above the lower groove 602, the rotation of the concave bracket 507 will not drive the upper connecting rod 608 to rotate.

[0088] For details, please refer to the following: Figure 10 The lifting and screening assembly 70 includes a reciprocating screw 701 connected to the top of the upper connecting rod 608 and rotatably connected to the inside of the waste screening chamber 201. A lifting slider 702 is connected to the outside of the reciprocating screw 701 via ball bearings. An assembly frame 703 is installed on the outside of the lifting slider 702 and slidably connected to the inside of the waste screening chamber 201. A protruding plate 704 is slidably connected at the center of the outside of the assembly frame 703. Multiple protruding plates 704 are installed at the center of the inner wall of the waste screening chamber 201. Multiple screening grids 705 are installed inside the assembly frame 703 and on the outside of the lifting slider 702. A waste extraction assembly 80 is located above the assembly frame 703.

[0089] In the device of the present invention for preventing daily dust suppression water from overflowing into rivers during sunny days, the screening grid plate 705 can automatically screen the wastewater during the separation of impurities. Simultaneously, when the upper connecting rod 608 rotates, it drives the reciprocating screw 701 connected to its top, causing the lifting slider 702 and the assembly frame 703 connected by ball bearings on the outside of the reciprocating screw 701 to move up and down (reciprocate). This allows the screening grid plate 705, located inside the assembly frame 703, to automatically move below the waste extraction assembly 80.

[0090] For details, please refer to the following: Figure 11The waste extraction assembly 80 includes multiple waste extraction nozzles 801, each of which is installed at the bottom of an extraction pipe 802. The waste extraction nozzles 801 are located inside the debris screening chamber 201, and the extraction pipe 802 extends to the outside of the wastewater treatment tank 20. A central pipe 803 is connected to the extraction pipes 802 and is located on the outside of the wastewater treatment tank 20. The central pipe 803 is connected to an air pump 804, which is connected to a storage tank 805. The air pump 804 is installed on the top of the storage tank 805, which is located on the outside of the wastewater treatment tank 20.

[0091] In the device of the present invention for preventing daily dust suppression water from overflowing into rivers during sunny days, when the screening grid plate 705 and impurities move to below the waste extraction nozzles 801, the air pump 804 operates to generate a suction force, which is transmitted to multiple waste extraction nozzles 801 through the central pipe 803 and the extraction pipe 802. At this time, the suction force generated by the waste extraction nozzles 801 can extract the impurities on the screening grid plate 705 and transmit them to the interior of the storage tank 805 for storage through the central pipe 803 and the extraction pipe 802.

[0092] In this invention, a one-way valve is provided in the connecting part between the air pump 804 and the storage tank 805, which can realize the one-way movement of impurities and waste materials.

[0093] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
