[0031] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0032] Combination Figure 1-Figure 7 The present invention discloses a water purification device for treating stone coal slag wastewater, comprising an outer cylinder 1 of the treatment device, the bottom of the outer cylinder 1 of the treatment device is fixedly connected with an annular bottom plate 12, a sedimentation treatment component 2 is installed inside the outer cylinder 1 of the treatment device, the sedimentation treatment component 2 comprises a sedimentation cylinder 201, and the sedimentation cylinder 201 is nested inside the outer cylinder 1 of the treatment device, and the sedimentation cylinder 201 is fixedly connected to the annular bottom plate 12, the top of the sedimentation cylinder 201 is fixedly connected with a drainage cylinder 202, and a drainage through hole 203 is opened on the side of the drainage cylinder 202, and the inner wall of the drainage cylinder 202 is fixedly connected to the drainage cylinder 202. There is a guide ring 204, the top of the drainage cylinder 202 is fixedly connected with an anti-turbulence partition plate 205, and the inner wall of the anti-turbulence partition plate 205 is fixedly connected with a guide plate 206, and the side of the guide plate 206 is fixedly connected with a stirring inner cylinder 207, and the interior of the outer cylinder 1 of the treatment device is also provided with a post-settlement water storage chamber 208, and the post-settlement water storage chamber 208 is composed of the anti-turbulence partition plate 205, the drainage through hole 203, the sedimentation cylinder 201, the annular bottom plate 12 and the outer cylinder 1 of the treatment device, and the inner cavity of the drainage cylinder 202 is connected to the post-settlement water storage chamber 208 through the drainage through hole 203.

[0033] The top of the outer cylinder 1 of the treatment device is fixedly connected with an enhanced filtration area 4, and the top of the enhanced filtration area 4 is fixedly connected with a clean water chamber 5, the top of the clean water chamber 5 is fixedly connected with a water outlet pipe 7, the bottom of the stirring inner cylinder 207 is fixedly connected with a wastewater inlet pipe 8, and the end of the wastewater inlet pipe 8 is fixedly connected with a pipeline mixer 9, the top of the pipeline mixer 9 is fixedly connected with a flocculant addition tank 10, and the end of the pipeline mixer 9 away from the wastewater inlet pipe 8 is fixedly connected with a liquid pump 11. Under the pumping action of the liquid pump 11, the stone coal deslagging wastewater first enters the pipeline mixer 9. Inside, open the valve of the flocculant adding tank 10, and the flocculant inside the flocculant adding tank 10 enters the interior of the pipeline mixer 9, mixes with the wastewater inside the pipeline mixer 9, and then enters the interior of the stirring inner cylinder 207 through the wastewater inlet pipe 8. The water after sedimentation and separation inside the sedimentation treatment component 2 is located inside the post-settlement water storage chamber 208, and under the action of pressure, passes through the enhanced filtration area 4 from the top of the post-settlement water storage chamber 208. The purified water finally enters the interior of the clean water chamber 5 and flows out of this purification device from the outlet pipe 7.

[0034] A mud collecting bucket 209 is fixedly connected to the bottom of the sedimentation cylinder 201, and a mud discharge pipe 210 is fixedly connected to the bottom of the mud collecting bucket 209, and a mud pump 211 is installed at the end of the mud discharge pipe 210. The precipitated solid matter is located inside the sedimentation cylinder 201. After the sedimentation and purification is completed, the mud pump 211 is started, and the coal slime sediment can follow the mud collecting bucket 209 and be led to the subsequent belt filter press through the mud discharge pipe 210 for filtration and molding, and the filtration wastewater returns to this purification device for recycling treatment.

[0035] The guide plate 206 is arranged in a circular array on the outside of the mixing inner cylinder 207. The guide plate 206 consists of an inclined portion and a vertical portion integrated at the bottom of the bent portion. The drainage holes 203 are arranged in three rows at equal intervals on the side of the drainage cylinder 202. The guide ring 204 is arranged to be gradually inclined downward from the outside to the inside, and the guide ring 204 and each row of drainage holes 203 are arranged at intervals. The mixing inner cylinder 207 is coaxially arranged inside the anti-turbulence partition plate 205, and the inner cavity of the mixing inner cylinder 207 is connected to the inner cavity of the anti-turbulence partition plate 205, and the inner cavity of the anti-turbulence partition plate 205, the inner cavity of the drainage cylinder 202 and the inner cavity of the sedimentation cylinder 201 are all connected.

[0036] After the wastewater and the flocculant undergo flocculation reaction inside the mixing inner cylinder 207, due to the continuous water inflow from the bottom, the water above will overflow from the top of the mixing inner cylinder 207. The guide plate 206 has a guiding effect on the overflowing water, so that the originally turbulent water flow changes to flow in a downward direction, creating good conditions for the subsequent sedimentation process, and then flows through the inner cavity of the drainage cylinder 202. The guide ring 204 causes the water flow to generate friction with the plate surface, consumes the kinetic energy of the water flow, and gradually slows down the flow rate. The reduced flow rate can give the suspended solid particles more time to settle to the bottom of the pool under the action of gravity, which is particularly conducive to the sedimentation and separation of tiny particles. At the same time, the inclined guide plate surface can provide some fine solid particles for attachment. Once the particles contact the guide plate, it is like finding a foothold, and they will slide downward along the plate surface and converge into the inside of the sedimentation cylinder 201 to avoid being engulfed by the water flow again, which indirectly speeds up the sedimentation efficiency. Then, under the action of pressure, the water flows out from each drainage through hole 203 to the inside of the water storage chamber 208 after sedimentation;

[0037] In the process of water overflowing from the mixing inner cylinder 207, finally entering the post-sedimentation water storage chamber 208, and flowing upward from the post-sedimentation water storage chamber 208 to the enhanced filtration area 4 for filtration, the water flow route is U-shaped. Due to the existence of the bend, the water flow streamline is forced to bend and elongate, and the actual flow rate of the water flow is significantly reduced. The lower the flow rate, the more time the particles have to settle under the action of gravity, and the easier it is to settle. When the water flow turns at the bottom, centrifugal force is generated. The water flow turns with the particles. Due to inertia, the particles with larger mass will be subjected to a greater centrifugal force than water, and will be thrown to the wall of the sedimentation cylinder 201, which further improves the separation effect of sediment and water.

[0038] A stirring assembly 6 is installed inside the stirring inner cylinder 207, and the stirring assembly 6 is used to stir the wastewater. The stirring assembly 6 includes a second servo motor 601, and the second servo motor 601 is fixedly connected to the top of the water purification chamber 5, and the output end of the second servo motor 601 is fixedly connected to a rotating shaft 603, and the outside of the rotating shaft 603 is interference-connected with a bearing 602, and the bearing 602 is nested in the inside of the water purification chamber 5, the outer wall of the rotating shaft 603 is fixedly connected to an upflow blade 604, and the upflow blade 604 is arranged at an equal angle with respect to the outer wall of the rotating shaft 603, and a stirring rod 605 is arranged at the bottom of the upflow blade 604, and the stirring rod 605 is evenly fixed to the outer wall of the rotating shaft 603.

[0039] The output end of the second servo motor 601 rotates inside the mixing inner cylinder 207 with the upflow blade 604 and the stirring rod 605 through the rotating shaft 603. The stirring rod 605 is used to stir the inside of the mixing inner cylinder 207 so that the wastewater and flocculant inside the mixing inner cylinder are fully mixed to improve the flocculation efficiency. At the same time, the rotating upflow blade 604 has an upward lifting effect on the water inside the mixing inner cylinder 207, causing the water inside the mixing inner cylinder 207 to gradually overflow from the top.

[0040] The outer sleeve of the drainage through hole 203 is provided with a rotary switch assembly 3, and the rotary switch assembly 3 is used to control the opening and closing of the drainage through hole 203. The rotary switch assembly 3 includes a flow control cylinder 301, and the flow control cylinder 301 is nested outside the drainage cylinder 202, and there is a clearance fit between the flow control cylinder 301 and the drainage cylinder 202. The side of the flow control cylinder 301 is provided with a drainage flow hole 302, and the drainage flow hole 302 corresponds to the drainage through hole 203 one by one. The outer wall of the flow control cylinder 301 is fixedly connected with a sawtooth Ring 303, and the side of the serrated ring 303 is meshed with a gear 304, a first servo motor 305 is installed at the bottom of the gear 304, and the first servo motor 305 is fixedly connected to the inner wall of the outer cylinder 1 of the processing device, the bottom of the flow control cylinder 301 is fixedly connected to a limiting rotating ring 306, and the external rotation of the guide plate 206 is connected to a limiting groove ring 307, the limiting groove ring 307 is sleeved on the outer wall of the sedimentation cylinder 201, and the limiting groove ring 307 is fixedly connected to the sedimentation cylinder 201.

[0041] During the sedimentation purification process, the drainage flow hole 302 and the drainage through hole 203 are in an aligned state. At this time, the water after sedimentation separation can flow outward through the drainage through hole 203 and the drainage flow hole 302 to the inside of the water storage chamber 208 after sedimentation. When the entire sedimentation purification process is completed and the sediment is discharged, the first servo motor 305 can be started, and its output end rotates with the gear 304, and then rotates with the flow control cylinder 301 through the serrated ring 303, so that the drainage flow hole 302 and the drainage through hole 203 are staggered, and the flow control cylinder 301 is used to block and block the drainage through hole 203, so that the water in the water storage chamber 208 after sedimentation that has been precipitated and separated will no longer flow back into the mud collecting bucket 209 and mix with the sediment.
