Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anti-flocculation device for coal mine wastewater treatment. Background Technology

[0002] Coal mining generates a large amount of wastewater, including mine water inflow, leaching wastewater from coal yards and gangue yards, etc. The wastewater from the same mine contains heavy metals such as iron and manganese, non-metallic substances such as sulfur, fluorine, and chlorine, as well as organic pollutants and suspended solids. Direct discharge of this mine wastewater will inevitably cause serious environmental pollution and waste a large amount of water resources, making it impossible to achieve the goal of a circular economy.

[0003] During the pipeline transportation of coal mine wastewater, if flocculation occurs, it will accumulate on the inner wall of the pipeline, occupying internal space, affecting transportation efficiency, and reducing the pipeline's service life. Therefore, anti-flocculation devices are needed to prevent coal mine wastewater from flocculating.

[0004] In existing technologies, conventional anti-flocculation devices for coal mine wastewater treatment mostly involve pouring anti-flocculation agents into the wastewater. However, the anti-flocculation agents and wastewater do not mix evenly, resulting in low mixing efficiency. Furthermore, it is impossible to add the corresponding dosage of anti-flocculation agents according to the flow rate of the wastewater, leading to poor anti-flocculation effects and a lack of filtration function for impurities. Utility Model Content

The right side of the scraper is movably fitted against the right side of the metal filter screen.

[0008] Furthermore, an electric slag discharge valve is fixedly installed in the middle of the lower side wall of the tank corresponding to the left side of the partition.

[0009] Furthermore, the stirring mechanism includes a motor, a transmission pipe, a liquid inlet, a stirring pipe, a one-way nozzle, and a rectangular sleeve. The motor is fixedly installed on the right side of the liquid distribution box, and a transmission pipe is fixedly installed on the left side of the output shaft of the motor. The transmission pipe passes through the liquid distribution box and is movably inserted into the tank body. A liquid inlet is opened on the front side wall of the transmission pipe corresponding to the liquid distribution box. Stirring pipes are provided on the upper, lower, left, and right sides of the transmission pipe inside the tank body. One-way nozzles are evenly arranged on the stirring pipe. A rectangular sleeve is fixedly installed on the left side of the stirring pipe, and the rectangular sleeve is movably fitted on the outside of the right end of the rotating shaft.

[0013] Compared with the prior art, this utility model provides a coal mine wastewater treatment anti-flocculation device, which has the following beneficial effects:

[0014] 1. This coal mine wastewater treatment anti-flocculation device uses an extraction mechanism to draw anti-flocculation agent into a mixing mechanism. The anti-flocculation agent is evenly distributed in the wastewater within the tank by the mixing mechanism, resulting in more uniform and faster mixing of the wastewater and anti-flocculation agent. Furthermore, a control mechanism monitors the wastewater flow rate and adjusts the flow rate of the extraction mechanism accordingly, allowing for precise control of the anti-flocculation agent dosage based on the wastewater flow rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model discloses a coal mine wastewater treatment anti-flocculation device, including a tank 1. A water inlet pipe 2 is fixedly installed on the left side wall of the tank 1 near the upper side. A partition 3 is fixedly installed on the inner wall of the tank 1 near the left side. A filter mechanism 4 is fixedly installed on the partition 3. A liquid distribution box 5 is fixedly installed on the right side of the tank 1. The left side of the liquid distribution box 5 is welded to the right side of the tank 1 to ensure a good sealing effect between the liquid distribution box 5 and the tank 1. A stirring mechanism 6 is fixedly installed on the liquid distribution box 5 and inserted into the tank 1. The stirring mechanism 6 is drivenly connected to the filter mechanism 4. The upper side wall of the liquid distribution box 5 is connected to a storage tank 8 through a extraction mechanism 7. The storage tank 8 is fixedly installed on the upper surface of the tank 1. A control mechanism 9 is provided on the storage tank 8. A water outlet pipe 10 is fixedly installed on the right side wall of the tank 1 near the lower edge.

[0023] Specifically, the filtration mechanism 4 includes a metal filter plate 401, a bearing assembly 402, a rotating shaft 403, and a scraper 404. The metal filter plate 401 is fixedly embedded in the partition plate 3. The rotating shaft 403 is installed in the middle of the metal filter plate 401 through the bearing assembly 402. The scraper 404 is fixedly installed on the rotating shaft 403 near the left side. The right side of the scraper 404 is movably attached to the right side of the metal filter plate 401.

[0024] In this embodiment, the metal filter plate 401 filters impurities in coal mine wastewater. The rotating shaft 403 can rotate in the bearing assembly 402 along with the stirring mechanism 6, so that the rotating shaft 403 drives the scraper 404 to rotate. The scraper 404 filters the impurities adhering to the metal filter plate 401, thereby achieving the effect of cleaning the metal filter plate 401 and effectively preventing it from clogging.

[0025] Specifically, an electric slag discharge valve 11 is fixedly installed in the middle of the lower side wall of the tank 1 corresponding to the left side of the partition 3.

[0026] In this embodiment, the electric slag discharge valve 11 can discharge the impurities filtered out by the metal filter screen 401 from the tank 1.

[0027] Specifically, the stirring mechanism 6 includes a motor 601, a transmission pipe 602, a liquid inlet 603, a stirring pipe 604, a one-way nozzle 605, and a rectangular sleeve 606. The motor 601 is fixedly installed on the right side of the liquid distribution box 5. The transmission pipe 602 is fixedly installed on the left side of the output shaft of the motor 601. The transmission pipe 602 passes through the liquid distribution box 5 and is movably inserted into the tank body 1. A liquid inlet 603 is opened on the front side wall of the transmission pipe 602 corresponding to the liquid distribution box 5. Stirring pipes 604 are arranged on the upper, lower, left, and right sides of the transmission pipe 602 inside the tank body 1. One-way nozzles 605 are evenly arranged on the stirring pipe 604. A rectangular sleeve 606 is fixedly installed on the left side of the stirring pipe 604, and the rectangular sleeve 606 is movably sleeved on the outside of the right end of the rotating shaft 403.

[0028] In this embodiment, the extraction mechanism 7 delivers the antiflocculation agent into the distribution tank 5. The antiflocculation agent in the distribution tank 5 flows into the transmission pipe 602 through the inlet hole 603, then into the stirring pipe 604 through the transmission pipe 602, and then is sprayed out through the one-way nozzle 605 in the stirring pipe 604. At this time, the output shaft of the motor 601 drives the transmission pipe 602 to rotate, and the transmission pipe 602 drives the stirring pipe 604 and the one-way nozzle 605 to rotate, so that the antiflocculation agent sprayed by the one-way nozzle 605 flows evenly into the wastewater in the tank 1, and mixes and stirs the wastewater and the antiflocculation agent, so that the antiflocculation agent and the wastewater are mixed more evenly and more efficiently. The rectangular sleeve 606 rotates with the transmission pipe 602, so that the rectangular sleeve 606 drives the rotating shaft 403 to rotate. The outer surface of the part of the rotating shaft 403 inserted into the rectangular sleeve 606 has a rectangular structure, so that the rectangular sleeve 606 can stably drive the rotating shaft 403 to rotate.

[0029] Specifically, mechanical seals 12 are provided on the left and right side walls of the liquid distribution tank 5 corresponding to the transmission pipe 602, and a through hole 13 is provided on the right side wall of the tank body 1 corresponding to the transmission pipe 602.

[0030] In this embodiment, the mechanical seal 12 improves the sealing effect between the transmission pipe 602 and the left and right side walls of the liquid distribution box 5, and the through hole 13 meets the needs of the transmission pipe 602 to pass through and rotate in the right side wall of the tank body 1.

[0031] Specifically, the extraction mechanism 7 includes a water pump 701 and a conduit 702. The water pump 701 is installed on the right side of the tank 1, and the inlet and outlet of the water pump 701 are connected to the liquid storage tank 8 and the liquid distribution tank 5 through the conduit 702, respectively.

[0032] In this embodiment, the water pump 701 draws the anti-flocculation agent from the storage tank 8 into the distribution tank 5 through the conduit 702.

[0033] Specifically, the control mechanism 9 includes a controller 901, an alarm 902, a liquid level sensor 903, a solenoid valve 904, and a liquid flow rate sensor 905. The controller 901 is installed on the front side of the liquid storage tank 8, and the alarm 902 is installed on the upper surface of the controller 901. The liquid level sensor 903 is embedded in the upper side wall of the liquid storage tank 8. The solenoid valve 904 and the liquid flow rate sensor 905 are installed on the outlet pipe 10 from left to right.

[0034] In this implementation scheme, the controller 901 is electrically connected to various electrical components. The liquid level sensor 903 monitors the liquid level of the antiflocculation agent in the storage tank 8. When the liquid level is lower than the set value, the information is fed back to the controller 901. The controller 901 then triggers the alarm 902 to remind the staff to add antiflocculation agent to the storage tank 8 in a timely manner. When the solenoid valve 904 opens, the wastewater in the tank 1 flows out through the outlet pipe 10. The liquid flow rate sensor 905 monitors the flow rate of the wastewater in the outlet pipe 10 and feeds back the wastewater flow rate information to the controller 901. The information processing module in the controller 901 processes the flow rate information and adjusts the speed of the water pump 701 through the frequency converter according to the flow rate information. This allows for adjustment of the dosage of antiflocculation agent added according to the wastewater inflow, making the dosage of antiflocculation agent in the wastewater more appropriate and improving the antiflocculation effect.

[0035] In use, connect the inlet pipe 2 to the coal mine wastewater pipeline to allow the coal mine wastewater to flow into the tank 1. Impurities in the wastewater are filtered through the metal filter screen 401 in the filter mechanism 4. The filtered coal mine wastewater flows into the right side of the tank 1. The controller 901 in the control mechanism 9 then turns on the water pump 701 in the extraction mechanism 7, causing the water pump 701 to draw the anti-flocculation agent from the storage tank 8 into the distribution tank 5 through the conduit 702. The anti-flocculation agent in the distribution tank 5 flows into the transmission pipe 602 through the inlet hole 603 in the stirring mechanism 6, and then into the stirring... The antiflocculation agent is sprayed out through the one-way nozzle 605 in the stirring pipe 604. At this time, the output shaft of the motor 601 drives the transmission pipe 602 to rotate, and the transmission pipe 602 drives the stirring pipe 604 and the one-way nozzle 605 to rotate, so that the antiflocculation agent sprayed by the one-way nozzle 605 flows evenly into the wastewater in the tank 1, and mixes and stirs the wastewater and antiflocculation agent, making the mixture more uniform and faster. The rectangular sleeve 606 rotates with the transmission pipe 602, so that the rectangular sleeve 606 drives the rotating shaft 403 to rotate. The rotating shaft 403 is inserted into the rectangular sleeve 606. The inner part has a rectangular outer surface, which allows the rectangular sleeve 606 to stably drive the rotating shaft 403 to rotate. The rotating shaft 403 then drives the scraper 404 to rotate. The scraper 404 filters impurities adhering to the metal filter screen 401, achieving the effect of cleaning the metal filter screen 401 and effectively preventing it from clogging. When the solenoid valve 904 opens, wastewater in the tank 1 flows out through the outlet pipe 10. The liquid flow rate sensor 905 monitors the wastewater flow rate in the outlet pipe 10 and feeds back the wastewater flow rate information to the controller 901. The controller 901 processes the information. The module processes the flow rate information and adjusts the speed of the water pump 701 via the frequency converter based on the flow rate information. This allows for adjustment of the dosage of antiflocculation agent added according to the wastewater inflow, ensuring a more appropriate dosage and better antiflocculation effect. The liquid level sensor 903 monitors the liquid level of the antiflocculation agent in the storage tank 8. When the liquid level is lower than the set value, the information is fed back to the controller 901, which triggers the alarm 902 to remind the staff to add antiflocculation agent to the storage tank 8 in a timely manner.

[0036] In summary, this anti-flocculation device for coal mine wastewater treatment makes the mixing of wastewater and anti-flocculation agent more uniform and faster. It can also adjust the dosage of anti-flocculation agent according to the flow rate of wastewater, resulting in better anti-flocculation effect of coal mine wastewater, increased impurity removal effect, and effective prevention of impurities from clogging subsequent wastewater pipelines.
