[0014] A method for using a coal mine wastewater treatment device comprises the following steps:

[0015] S1: Install the shell at the required position, then install the water inlet pipe at the water inlet, install the drain outlet 2, connect the pipe to the drain outlet 4 of the sewage discharge structure, and connect the power supply to the motor. This equipment is equipped with a stirring mechanism, a sewage discharge mechanism, and a filtering mechanism, which can filter large and small gravel at the same time. At the same time, the first-level filter net can perform fine filtering;

[0016] S2: The stirring mechanism is driven by a motor to drive the rotating shaft, which drives each fan blade to stir. This equipment adds a fan blade scraper on the fan blade. When the fan blade rotates, the agent barrel nozzle starts to spray the agent, so that the impurities in the mud and water begin to separate. Some of them will settle on the fan blade over time. When the fan blade scraper on the fan blade is in the water flow and rotates, the force generated will push the fan blade scraper to the top of the fan blade. When the fan blade rotates to the top of the rotating shaft, it will break away from the water flow surface. In addition, a reset spring is set on the fan blade scraper, which will move the fan blade scraper downward, and the reciprocating movement has the effect of cleaning the rotating fan blade.

[0017] S3: The rotating shaft passes through the housing and is fixedly connected to gear 1, gear 1 drives gear 2, the structural box provides support for the connecting shaft, gear 2 is fixedly connected to the connecting shaft, the connecting shaft drives gear 3, gear 3 drives gear 4, gear 4 is fixedly connected to transmission shaft 1, transmission shaft 1 is fixedly connected to the rotating disk, the horizontal bar in the middle of the rotating disk near the outer part is rotatably connected to connecting rod 1, connecting rod 1 is rotatably connected to connecting frame 1, connecting frame 1 and connecting frame 2 are directly fixedly connected by connecting rod 2, when the rotating disk rotates, it can drive connecting frame 1 and connecting frame 2 to do repeated linear motion, connecting rod 2 It is slidably connected to the shell, so that when the rotating disk rotates, the force in other directions is prevented from being biased to the connecting rod 2, the connecting frame 1 and the connecting frame 2. The lower ends are respectively connected to the baffle 1, the baffle 2, the scraper 1 and the scraper 2. The top of the scraper is rotatably connected to the baffle. When the scraper is repeatedly moved to scrape off the sediment, the scraper will scrape off the sediment into the sewage outlet 1 and the sewage outlet 2 respectively. When the scraper is reset, because there is no baffle at the other end, driven by the water flow, the scraper is not subject to the force driven by the baffle when it is reset through the rotating connection, thereby avoiding driving the sediment when resetting, causing secondary turbidity.

[0018] S4: The force of the rotating disk drives the transmission shaft 2, which is then connected by a chain to drive the transmission shaft 3. When the transmission shaft 3 drives the auger, two sewage discharge grooves are opened on one side of the outer wall of the auger fixedly connected to the shell. When the scraper discharges the sediment from the sewage outlet 1 and the sewage outlet 2 to the sewage discharge mechanism, the auger set in the sewage discharge mechanism rotates. Due to the force of the chain, the auger moves, so that the sediment scraped from the sewage outlet 1 and the sewage outlet 2 is transported centrally and discharged from the sewage outlet 4.

[0019] S5: The rotation force of the auger drives the transmission wheel 1, which is fixedly connected to the auger and rotationally connected to the transmission round pipe. The belt drives the transmission shaft 4, which drives the cam to rotate. The cam pushes the fitting wheel, and the fitting wheel drives the push rod to move repeatedly. The cam rotates in a triangular shape. When it rotates to one end of the cam angle, the push rod extends the most forward. When the cam rotates to the plane, the push rod extends backward under the action of spring 2 to make the fitting wheel fit the cam surface. The two cams cooperate with the two push rods to repeatedly move the screen 1 and the screen 2 in a straight line. The mesh 1 and the mesh 2 of the two screens show a cross effect. Due to the reciprocating push of the cam, the mesh 1 and the mesh 2 will cross, which will make the filter mesh smaller. When the mesh 1 and the mesh 2 move to the separated state, the mesh cross becomes larger, which can effectively prevent the mesh from being blocked by gravel and the like.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention aims at the problem that although the existing technology can separate large and small gravel in wastewater, it is still necessary to filter the smaller gravel and mud after separating the larger gravel, and one device cannot meet the filtering requirements. The present device is provided with a stirring mechanism, a sewage discharge mechanism, and a filtering mechanism, which can filter large and small gravel at the same time. The primary filter screen provided at the same time can perform fine filtering. The stirring mechanism is driven by a motor to drive the rotating shaft, and the rotating shaft drives each fan blade to stir. The present device adds a fan blade scraper to the fan blade. When the fan blade rotates, the medicine barrel nozzle starts to spray medicine, so that the impurities in the muddy water begin to separate. Over time, some of them will be deposited on the fan blade. When the fan blade scraper on the fan blade is in the water flow and rotates, the force generated will push the fan blade scraper to the top of the fan blade. When the fan blade rotates to the top of the rotating shaft, it will break away from the water flow surface. In addition, a reset spring is provided on the fan blade scraper, which will cause the fan blade scraper to move downward, and the reciprocating movement has the effect of cleaning the rotating fan blade.

[0022] (2) The present invention utilizes the force of the above-mentioned rotating shaft. The rotating shaft penetrates the housing and is fixedly connected to gear one. Gear one drives gear two. The structural box provides support force for the connecting shaft. Gear two is fixedly connected to the connecting shaft. The connecting shaft drives gear three. Gear three drives gear four. Gear four is fixedly connected to transmission shaft one. Transmission shaft one is fixedly connected to the rotating disk. The horizontal bar in the middle of the rotating disk near the outer side is rotatably connected to connecting rod one. Connecting rod one is rotatably connected to connecting frame one. Connecting frame one and connecting frame two are directly fixedly connected by connecting rod two. When the rotating disk rotates, it can drive connecting frame one and connecting frame two to make repeated straight lines. Movement, connecting rod two and the shell are slidingly connected, which avoids the force in other directions from being biased to connecting rod two, connecting frame one and connecting frame two when the rotating disk rotates. The lower ends are respectively connected to baffle one, baffle two, scraper one and scraper two. The top of the scraper is rotatably connected to the baffle. When repeated movements are performed to scrape off the sediment, the scraper will scrape the sediment into sewage outlet one and sewage outlet two respectively. When the scraper is reset, because there is no baffle at the other end, driven by the water flow, the scraper is not affected by the force driven by the baffle when it is reset through the rotating connection, thereby avoiding driving the sediment during reset to cause secondary turbidity.

[0023] (3) The present invention utilizes the force of the rotating disk to drive the transmission shaft 2, which is then connected by a chain to drive the transmission shaft 3. When the transmission shaft 3 drives the auger, two sewage discharge grooves are opened on one side of the outer wall of the auger that is fixedly connected to the shell. When the scraper discharges the sediment from the sewage outlet 1 and the sewage outlet 2 to the sewage discharge mechanism, the auger arranged in the sewage discharge mechanism rotates. The auger is driven to move by the force of the chain, so that the sediment scraped in from the sewage outlet 1 and the sewage outlet 2 is transported in a centralized manner and discharged from the sewage outlet 4. Through the application of the above components, the sediment in the two water chambers is collected and discharged in a centralized manner.

[0024] (4) Two repeatedly sliding screens are arranged on the inner side of the front section of the housing of the device of the present invention, namely, screen 1 and screen 2. When the machine is turned on, the rotation force of the auger drives the transmission wheel 1, which is fixedly connected to the auger and rotatably connected to the transmission round pipe. The transmission shaft 4 is then driven by the belt, and the transmission shaft 4 drives the cam to rotate. The cam pushes the fitting wheel, and the fitting wheel drives the push rod to move repeatedly. The cam rotates in a triangular shape. When the push rod is rotated to one end of the cam angle, it extends the most forward. When the cam rotates to a plane, the push rod extends backward under the action of spring 2 to make the fitting wheel fit the cam surface. The two cams cooperate with the two push rods to repeatedly move the screen 1 and the screen 2 in a straight line. The mesh 1 and the mesh 2 of the two screens show a cross effect. Due to the reciprocating push of the cam, the mesh 1 and the mesh 2 will cross, which will make the filter mesh smaller. When the mesh 1 and the mesh 2 move to the separated state, the mesh cross becomes larger, which can effectively prevent the mesh from being blocked by gravel and sand, thereby improving the filtering effect and service life of the equipment.

Two push rods 67 are slidably connected to the outer wall of the shell 1. The ends of the two push rods 67 away from the shell 1 are fixedly connected to two fitting wheels 65. Springs 2 66 are wound around the outer walls of the two push rods 67. One end of the two springs 2 66 is fixedly connected to the shell 1.

The mesh 1 601 and the mesh 2 602 of the two screens show a cross effect. Due to the reciprocating push of the cam 64, the filter mesh size will become smaller when the mesh 1 601 and the mesh 2 602 cross. When the mesh 1 601 and the mesh 2 602 move to a separated state, the mesh size cross becomes larger, which can effectively prevent the mesh from being blocked by gravel and the like, thereby improving the filtering effect and service life of the equipment.

[0049] A specific application of this embodiment is: before use, the shell 1 is installed at the desired position, and then a water pipe is installed at the water inlet 11, a drain outlet 13 is installed, and a pipe is connected to the drain outlet 4 16 of the sewage discharge structure to connect the motor with power. The device is provided with a stirring mechanism 2, a sewage discharge mechanism 4, and a filtering mechanism, which can filter large and small gravel at the same time, and a primary filter 5 is provided at the same time, which can perform fine filtering. The stirring mechanism 2 is driven by a motor 6 to drive a rotating shaft 22, and the rotating shaft 22 drives each fan blade 23 to stir. The device adds a fan blade scraper 25 to the fan blade 23. When the fan blade 23 rotates, the nozzle 27 of the medicine barrel 26 starts to spray medicine, so that the impurities in the mud and water begin to separate. Over time, some of them will be deposited on the fan blade 23. When the fan blade scraper 25 on the fan blade 23 is in the water flow and rotates, the force generated will push the fan blade scraper 25 to the top of the fan blade 23. When the fan blade 23 rotates to the top of the rotating shaft 22, it will break away from the water flow surface. In addition, a reset spring 24 is provided on the fan blade scraper 25, which will cause the fan blade scraper 25 to move downward, and the reciprocating back and forth has an effect of cleaning the rotating fan blade 23.

[0050] The rotating shaft 22 penetrates the housing 1 and is fixedly connected to the gear 1 31, the gear 1 31 drives the gear 2 32, the structural box 36 provides support for the connecting shaft 33, the gear 2 32 is fixedly connected to the connecting shaft 33, the connecting shaft 33 drives the gear 3 34, the gear 3 34 drives the gear 4 35, the gear 4 35 is fixedly connected to the transmission shaft 1 37, the transmission shaft 1 37 is fixedly connected to the rotating disk 38, the cross bar in the middle of the rotating disk 38 close to the outer side is rotatably connected to the connecting rod 1 39, the connecting rod 1 39 is rotatably connected to the connecting frame 1 41, the connecting frame 1 41 and the connecting frame 2 45 are directly fixedly connected by the connecting rod 2 44, and when the rotating disk 38 rotates, it can drive the connecting frame 1 41 and the connecting frame 2 4 5. Repeated linear motion is performed. The connecting rod 2 44 is slidably connected to the housing 1 to avoid the force in other directions from being biased to the connecting rod 2 44, the connecting frame 1 41 and the connecting frame 2 45 when the rotating disk 38 rotates. The lower ends are respectively connected to the baffle 1 42, the baffle 2 46, the scraper 1 43, and the scraper 2 47. The top of the scraper is rotatably connected to the baffle. When performing repeated motions to scrape off the sediment, the scraper will scrape the sediment into the sewage outlet 1 14 and the sewage outlet 2 15 respectively. When the scraper is reset, because there is no baffle at the other end, driven by the water flow, the scraper is not subject to the force driven by the baffle when it is reset through the rotating connection, thereby avoiding driving the sediment during the reset to cause secondary turbidity.

[0051] The force of the rotating disk 38 drives the transmission shaft 2 51, which is then connected to the transmission shaft 3 55 by the chain 53. When the transmission shaft 3 55 drives the auger 56, the outer wall 57 of the auger is fixedly connected to one side of the outer shell 1 and has two sewage discharge grooves. When the scraper discharges the sediment from the sewage outlet 1 14 and the sewage outlet 2 15 to the sewage discharge mechanism 4, the auger 56 arranged in the sewage discharge mechanism 4 rotates. The force of the chain 53 drives the auger to move, so that the sediment scraped in from the sewage outlet 1 14 and the sewage outlet 2 15 is transported together and discharged from the sewage outlet 4 16.

[0052] When the machine is turned on, the rotational force of the auger 56 drives the transmission wheel 61, which is fixedly connected to the auger 56 and rotationally connected to the transmission tube 57. The transmission shaft 4 63 is then driven by the belt 62, and the transmission shaft 4 63 drives the cam 64 to rotate. The cam pushes the fitting wheel 65, and the fitting wheel 65 drives the push rod 67 to move repeatedly, and the cam 64 rotates in a triangular shape. When rotating to one end of the cam 64 angle, the push rod 67 is extended farthest forward, and when the cam 64 rotates to a plane, the push rod 67 extends backward under the action of the spring 2 66 to make the fitting wheel 65 fit the surface of the cam 64. The two cams 64 cooperate with the two push rods 67 to perform repeated linear motions on the screen 1 68 and the screen 2 69. The mesh 1 601 and the mesh 2 602 of the two screens show a cross effect. Due to the reciprocating push of the cam 64, the filter mesh size will become smaller when the mesh 1 601 and the mesh 2 602 cross. When the mesh 1 601 and the mesh 2 602 move to a separated state, the mesh size cross becomes larger, which can effectively prevent the mesh from being blocked by gravel and the like, thereby improving the filtering effect and service life of the equipment.

9. A method for using a coal mine wastewater treatment device, using the coal mine wastewater treatment device as claimed in claim 8, characterized in that: The steps include: S1: Install the housing (1) at the desired position, then install the water inlet pipe at the water inlet 1 (11), install the drain outlet 2 (13), connect the pipe to the drain outlet 4 (16) of the drain structure, and connect the power supply to the motor. The device is provided with a stirring mechanism (2), a drain mechanism (4), and a filtering mechanism, which can filter large and small gravel at the same time, and the primary filter (5) provided at the same time can perform fine filtering; S2: The stirring mechanism (2) is driven by a motor (6) to rotate the shaft (22), and the shaft (22) drives each blade (23) to stir. The device adds a blade scraper (25) to the blade (23). When the blade (23) rotates, the spray head (27) of the medicine barrel (26) starts to spray medicine, so that impurities in the muddy water begin to separate. Over time, some of them will be deposited on the blade (23). When the blade scraper (25) on the blade (23) is in the water flow and rotates, the force generated will push the blade scraper (25) to the top of the blade (23). When the blade (23) rotates to the top of the rotating shaft (22), it will be separated from the water flow surface. In addition, a reset spring (24) is provided on the blade scraper (25), which will cause the blade scraper (25) to move downward, and the reciprocating movement has an effect of cleaning the rotating blade (23); S3: The rotating shaft (22) passes through the housing (1) and is fixedly connected to the gear 1 (31). The gear 1 (31) drives the gear 2 (32). The structural box (36) provides support for the connecting shaft (33). The gear 2 (32) is fixedly connected to the connecting shaft (33). The connecting shaft (33) drives the gear 3 (34). The gear 3 (34) drives the gear 4 (35). The gear 4 (35) is fixedly connected to the transmission shaft 1 (37). The transmission shaft 1 (37) is fixedly connected to the rotating disk (38). The horizontal bar at the middle of the rotating disk (38) close to the outer side is rotatably connected to the connecting rod 1 (39). The connecting rod 1 (39) is rotatably connected to the connecting frame 1 (41). The connecting frame 1 (41) and the connecting frame 2 (45) are directly fixedly connected by the connecting rod 2 (44). When the rotating disk (38) rotates, it can drive The connecting frame 1 (41) and the connecting frame 2 (45) perform repeated linear motions, and the connecting rod 2 (44) is slidably connected to the housing (1), thereby preventing the force in other directions from biasing the connecting rod 2 (44) when the rotating disk (38) rotates. The lower ends of the connecting frame 1 (41) and the connecting frame 2 (45) are respectively connected to the baffle 1 (42), the baffle 2 (46), the scraper 1 (43), and the scraper 2 (47). The top of the scraper is rotatably connected to the baffle. When performing repeated motions to scrape off sediment, the scraper will scrape off the sediment into the sewage outlet 1 (14) and the sewage outlet 2 (15). When the scraper is reset, because there is no baffle at the other end, the scraper is driven by the water flow and is not subject to the force driven by the baffle when it is reset through the rotation connection, thereby preventing the sediment from being driven during the reset, causing secondary turbidity. S4: The force of the rotating disk (38) drives the transmission shaft 2 (51), which is then connected to the transmission shaft 3 (55) by the chain (53). When the transmission shaft 3 (55) drives the auger (56), the outer wall (57) of the auger is fixedly connected to the housing (1) and has two drainage grooves. When the scraper discharges the sediment from the drainage port 1 (14) and the drainage port 2 (15) to the drainage mechanism (4), the auger (56) arranged in the drainage mechanism (4) rotates. The force of the chain (53) drives the auger to move, so that the sediment scraped from the drainage port 1 (14) and the drainage port 2 (15) is transported together and discharged from the drainage port 4 (16). S5: The rotational force of the auger (56) drives the transmission wheel 1 (61), which is fixedly connected to the auger (56) and rotationally connected to the transmission tube (57), and then drives the transmission shaft 4 (63) through the belt (62), and the transmission shaft 4 (63) drives the cam (64) to rotate, and the cam drives the fitting wheel (65), and the fitting wheel (65) drives the push rod (67) to move repeatedly, and the cam (64) rotates in a triangular shape. When the push rod (67) is rotated to one end of the cam (64) angle, it extends most forward. When the cam (64) rotates to a plane, the push rod (67) extends backward under the action of the second spring (66) to make the fitting wheel (65) fit the surface of the cam (64). The two cams (64) cooperate with the two push rods (67) to repeatedly move the screen mesh 1 (68) and the screen mesh 2 (69). The mesh mesh 1 (601) and the mesh mesh 2 (602) of the two screen meshes present a cross effect. Due to the reciprocating push of the cam (64), the mesh mesh 1 (601) and the mesh mesh 2 (602) cross, which makes the filter mesh smaller. When the mesh mesh 1 (601) and the mesh mesh 2 (602) move to a separated state, the mesh cross becomes larger, which can effectively prevent the mesh from being blocked by gravel and the like.
