During the settlement process, the waste water keeps moving, and new waste water keeps entering the settlement part. After the settlement is completed, the clean water in the independent settlement area is discharged through the drainage part. After the drainage is completed, the waterproof conveying belt continues to drive the solid settlement layer to move to the filter press roller. The filter press roller filters the solid settlement layer. During the treatment of waste water, there is no need to stop and wait for the waste water to settle, which is beneficial to improve the working efficiency of the waste water treatment process. 2. When the ring chain rotates, the positioning disc rotates synchronously, and the positioning disc rotates around the positioning column while driving the fixed disc to rotate. Under the limiting action of the chain wheel one and the chain wheel two on the synchronous chain, the fixed disc rotates around the positioning column while rotating around its own axis. At this time, the positioning groove of the fixed disc always maintains a vertical state. When the fixed block moves to the positioning disc, the positioning groove is opposite to the fixed block. The ring chain rotates to make the fixed block enter the positioning groove. At this time, the fixed disc limits the fixed block, so that the water stop plate remains vertical when entering the settlement part, which is beneficial to improve the continuity of the fixed block entering the limiting groove.

[0035] The embodiment of the present application discloses a mine water treatment device. Embodiment

[0036] With reference to Figure 1 and Figure 2 A mine water treatment device, comprising a rack 1, a waterproof conveying belt 12 is arranged on the upper end of the rack 1 along the length direction, it is to be explained that the waterproof conveying belt 12 refers to the material of the conveying belt body is water-proof material, for example, rubber, two side plates 14 are fixedly connected to the upper end of the rack 1 along the length direction, the lower end surface of the side plate 14 is in abutment and fit with the upper end surface of the waterproof conveying belt 12, and a rubber sealing strip is arranged at the joint of the side plate 14 and the waterproof conveying belt 12. The two side plates 14 are parallel to each other and are respectively located on both sides of the waterproof conveying belt 12 along the width direction. The upper end of the rack 1 is also provided with a water baffle 13, the water baffle 13 is located at the same end of the two side plates 14 along the length direction and is fixed with the side plate 14, and the lower end of the water baffle 13 is also fit with the upper end surface of the waterproof conveying belt 12.

[0037] With reference to Figure 1 and Figure 2 The water baffle 13 and the two side plates 14 cooperate to form a settling part on the upper end surface of the waterproof conveying belt 12, a liquid inlet pipe 11 is installed on the side of the rack 1 close to the water baffle 13, one end of the liquid inlet pipe 11 extends into the settling part, for conveying the wastewater mixed with flocculating agent into the settling part. A filter press roller 5 is installed on the end of the rack 1 away from the water baffle 13, the waterproof conveying belt 12 drives the wastewater to move along the direction indicated by the water baffle 13 to the filter press roller 5 when working.

[0038] With reference to Figure 1 and Figure 2 A plurality of water blocking plates 2 are arranged on the upper end of the rack 1, the water blocking plates 2 are arranged along the length direction of the rack 1, the rack 1 is provided with a driving member for driving the water blocking plates 2 to move, the driving member comprises two groups of annular chains 31 and a power part 32, the annular chains 31 are arranged along the length direction of the rack 1, the rack 1 is provided with sprockets matched with the annular chains 31 along the length direction, the sprockets are rotatably connected to the rack 1 along the vertical direction, the annular chains 31 are arranged outside the corresponding sprockets and are engaged with the sprockets. The power part 32 is installed on one side of the rack 1, specifically, a motor, for driving the sprockets to rotate, the sprockets drive the annular chains 31 to rotate when rotating.

[0039] With reference to Figure 2 and Figure 3Two ring chains 31 are located on both sides of the frame 1 along the width direction and parallel to each other, all the water blocking plates 2 are located between the two ring chains 31, the outer circle of the ring chain 31 is circumferentially fixed with a plurality of connecting blocks 311, and the ring chain 31 drives the connecting block 311 to move when moving. The water blocking plate 13 is arranged vertically, and the upper end of the water blocking plate 13 is fixedly connected with a rotating rod 21 corresponding to the connecting block 311, the rotating rod 21 penetrates through the connecting block 311 and is vertically rotatably connected with the connecting block 311.

[0040] With reference to Figure 2 and Figure 3 , the ring chain 31 drives the water blocking plate 2 to move through the connecting block 311 cooperating with the rotating rod 21 when moving, and under the action of gravity, the side of the water blocking plate 2 away from the rotating rod 21 naturally droops during the movement of the water blocking plate 2. The water blocking plate 2 enters the settling part after moving to the lower end of the ring chain 31, at this time, the lower end of the water blocking plate 2 is close to the upper end surface of the waterproof conveying belt 12, and the side edge of the water blocking plate 2 along the length direction is close to the side plate 14, so that the water blocking plate 2 separates the wastewater in the settling part. At any time, the water blocking plate 2 at the lower end of the ring chain 31 is not less than three, at this time, any two adjacent water blocking plates 2 cooperate to form an independent settling part.

[0041] With reference to Figure 2 and Figure 3 , the waterproof conveying belt 12 drives the wastewater in the independent settling area to move in cooperation with the water blocking plate 2, and separates the wastewater in the independent settling area from the rest of the wastewater, thereby reducing the probability of the wastewater entering the settling part along the liquid inlet pipe 11 causing the wastewater in the independent settling area to fluctuate, keeping the wastewater in the independent settling area stable, and improving the settling effect of the wastewater in the independent settling area.

[0042] With reference to Figure 2 and Figure 3 , the frame 1 is provided with a positioning assembly for keeping the water blocking plate 2 vertical when moving in the settling part. The positioning assembly includes a fixed block 61 and a guide rail 62. The fixed block 61 corresponds to the rotating rod 21 one by one, and is fixedly connected to the end of the rotating rod 21 away from the water blocking plate 2. The connecting block 311 is located between the fixed block 61 and the water blocking plate 2, and the fixed block 61 drives the water blocking plate 2 to overturn when rotating.

[0043] With reference to Figure 2 and Figure 3The guide rail 62 is arranged along the length direction of the rack 1 and fixedly connected with the rack 1. The guide rail 62 is provided with a limiting groove 621 along the length direction. When the water blocking plate 2 moves to the lower end of the ring chain 31, the corresponding fixed block 61 is opposite to the limiting groove 621. The fixed block 61 is provided with an abutting surface on both sides along the vertical direction. The abutting surface is a plane. When the water blocking plate 2 moves along the rack 1, the fixed block 61 is driven to enter the limiting groove 621, and the abutting surface of the fixed block 61 is attached to the inner wall of the limiting groove 621. The guide rail 62 limits the fixed block 61 through the limiting groove 621, limits the deflection of the fixed block 61 along the vertical direction, and further reduces the probability of shaking of the water blocking plate 2 after forming an independent settlement area, and improves the water blocking effect of the water blocking plate 2.

[0044] With reference to Figure 2 and Figure 3 The rack 1 is rotationally connected with a plurality of positioning discs 7. The positioning disc 7 is located at the end of the ring chain 31 along the length direction and rotates along the vertical direction. The positioning disc 7 corresponds to the sprocket one 151 at the end of the ring chain 31, and the positioning disc 7 is coaxially fixed with the corresponding sprocket. The sprocket drives the corresponding positioning disc 7 to rotate when rotating. The positioning disc 7 is rotationally connected with a fixed disc 71 on the side close to the ring chain 31. The fixed disc 71 is rotationally connected with the positioning disc 7 along the vertical direction. The positioning disc 7 drives the fixed disc 71 to move when rotating.

[0045] With reference to Figure 2 and Figure 3 The rack 1 is fixedly provided with a positioning column 15. The positioning column 15 penetrates through the positioning disc 7 and is coaxially rotationally connected with the positioning disc 7. The positioning column 15 is coaxially fixedly provided with the sprocket one 151. The fixed disc 71 is coaxially fixed with the sprocket two 72 corresponding to the sprocket one 151. The sprocket one 151 and the sprocket two 72 are provided with a synchronous chain 73. The synchronous chain 73 is wound between the sprocket one 151 and the sprocket two 72 and engaged with the sprocket one 151 and the sprocket two 72. The sprocket one 151 is in a fixed state. Under the connection action of the synchronous chain 73, when the fixed disc 71 rotates around the positioning column 15, the rotation of the fixed disc 71 along the circumference is limited, and the fixed disc 71 relatively rotates with the positioning disc 7 when the positioning disc 7 rotates.

[0046] With reference to Figure 2 and Figure 3The positioning groove 711 of the fixed disc 71 is kept in vertical state during the movement of the fixed disc 71 driven by the positioning disc 7. When the water blocking plate 2 approaches the positioning disc 7, the fixed block 61 gradually approaches the fixed disc 71, and the annular chain 31 continues to move, so that the fixed block 61 enters the positioning groove 711 and abuts against the inner wall of the positioning groove 711. At this time, the fixed disc 71 limits the fixed block 61 and the water blocking plate 2, thereby reducing the probability of deflection of the water blocking plate 2 when the water blocking plate 2 preliminarily contacts the wastewater. The fixed disc 71 is staggered with the guide rail 62, which is beneficial to improve the continuity of the fixed block 61 entering the limiting groove 621 and improve the blocking effect of the water blocking plate 2 on the wastewater.

The two side plates 14 are provided with a plurality of vertical movement grooves 141 on the side close to each other. The movement grooves 141 are arranged along the length direction of the side plate 14. The movement grooves 141 correspond to the drainage parts one by one, and a filter plate 142 is arranged in the movement groove 141. The filter plate 142 blocks the opening of the movement groove 141 close to the water blocking plate 2.

[0048] With reference to Figure 4 and Figure 5 When the waterproof conveying belt 12 drives the wastewater to move slowly, the wastewater in the independent sedimentation area gradually settles and forms a solid sedimentation layer and a clear water layer. The clear water layer passes through the filter plate 142 and enters the movement groove 141 when passing through the movement groove 141. The floating block 43 is located in the movement groove 141, and the floating block 43 floats under the action of the buoyancy when the clear water enters the movement groove 141. The drainage pipe 41 penetrates through the side plate 14 and extends into the movement groove 141, and one end of the drainage pipe 41 in the movement groove 141 is communicated with a hose 44. The hose 44 penetrates through the floating block 43 from top to bottom and extends below the floating block 43. The lower end of the hose 44 is located in the clear water after the clear water enters the movement groove 141, and the floating block 43 moves to drive the hose 44 to move synchronously.

[0049] With reference to Figure 1 and Figure 5The drainage pump 42 is installed outside the rack 1, all the drainage pipes 41 are communicated with the drainage pump 42, when the drainage pump 42 works, the clean water in the moving groove 141 is sucked through the drainage pipe 41 and the hose 44, and then the clean water in the independent sedimentation area is discharged. The lower end of the hose 44 is fixedly provided with an abutting plate 45, the side close to the floating block 43 of the abutting plate 45 is fixedly provided with a water blocking ring 46 in the circumferential direction, and the position close to the abutting plate 45 of the hose 44 is opened in the circumferential direction and has a plurality of water inlets 441. When the solid particles penetrate into the moving groove 141 and the clean water in the moving groove 141 is less, the floating block 43 drives the hose 44 to be close to the solid particles. At this time, the hose 44 is in contact with the solid particles through the abutting plate 45, only the clean water with a height higher than the water blocking ring 46 enters the water blocking ring 46, and passes through the water inlet 441 and enters the hose 44, which is beneficial to reduce the probability of the solid particles being sucked into the hose 44.

[0050] With reference to Figure 1 and Figure 5 , the water blocking ring 46 is opened in the circumferential direction and has a spiral groove 461, the spiral groove 461 is arranged along the axis direction of the water blocking ring 46, and the water blocking ring 46 is coaxially rotated outside and has a blocking ring 47, the outer circle of the blocking ring 47 is opened in the axis direction and has a through port 471. When the through port 471 is aligned with the spiral groove 461, the clean water in the moving groove 141 sequentially passes through the through port 471 and the spiral groove 461 and enters the water blocking ring 46, the through port 471 is communicated with different positions of the spiral groove 461 by rotating the blocking ring 47, and then the position of the water blocking ring 46 communicated with the moving groove 141 is adjusted, which is convenient for sucking clean water with different heights.

[0051] With reference to Figure 1 , the upper end of the rack 1 is also fixedly provided with a plurality of mud separating blocks 18, the plurality of mud separating blocks 18 are located on the side away from the liquid inlet pipe 11 of the ring chain 31, and the plurality of mud separating blocks 18 are arranged along the width direction of the rack 1, and the rack 1 is provided with a cross arm for supporting the mud separating block 18. The mud separating block 18 is arranged in the vertical direction, and the lower end is close to the waterproof conveying belt 12, when the water blocking plate 2 moves to the end of the ring chain 31 away from the liquid inlet pipe 11 and gradually moves upward along with the ring chain 31, at this time, the water blocking plate 2 moves out of the solid sedimentation layer, and the solid sedimentation layer moves close to the mud separating block 18 under the action of the waterproof conveying belt 12.

[0052] With reference to Figure 1, the diameters of the mud blocks 18 in the vertical and horizontal directions gradually increase in the direction from the liquid inlet pipe 11 to the filter roller 5. When the solid sediment layer contacts the mud blocks 18, the mud blocks 18 divide the solid sediment layer, so that the solid sediment layer forms a water collecting groove in the conveying direction of the waterproof conveying belt 12. Under the action of gravity, the water in the solid sediment layer collects in the water collecting groove. The rack 1 is further provided with water suction pipes 19 corresponding to the mud blocks 18. The rack 1 is further provided with a support plate for supporting the water suction pipes 19. The lower ends of the water suction pipes 19 extend into the water collecting groove. One side of the rack 1 is provided with a water suction pump 191. All the water suction pipes 19 are in communication with the water suction pump 191. When the water suction pump 191 works, it discharges the collected clean water in the water collecting groove through the water suction pipes 19, further improving the water removal effect of the solid sediment layer.

[0053] With reference to Figure 1 , the two side plates 14 are each fixedly provided with a converging plate 81 between the mud blocks 18 and the annular chain 31. The converging plate 81 gradually moves away from the side plate 14 along the length direction of the side plate 14. When the solid sediment layer passes through the converging plate 81, the converging plate 81 pushes the solid sediment layer away from the side plate 14 through the inclined side, so that the position of the waterproof conveying belt 12 close to the side plate 14 is exposed to the outside. The water suction pipes 19 and the filter cylinder are further provided with a plurality of push rods 82 arranged in the width direction of the rack 1. The lower ends of the push rods 82 are close to the waterproof conveying belt 12. The rack 1 is provided with an electric push rod 84. The upper ends of all the push rods 82 are fixedly connected with the same horizontal rod 83. The horizontal rod 83 is slidably connected with the rack 1 along the width direction of the rack 1. The output shaft of the electric push rod 84 is fixedly connected with the horizontal rod 83. When the electric push rod 84 works, it drives the horizontal rod 83 to move. When the horizontal rod 83 moves, it divides a drainage groove on the solid sediment layer along the horizontal direction, which is connected with all the water collecting grooves.

[0054] With reference to Figure 1 When the clean water collected in the water collecting groove is less, the water suction pipes 19 are not easy to suck. At this time, the residual clean water in the water collecting groove is discharged from the drainage groove and flows into the space left by the converging plate 81 on the side of the solid sediment layer under the action of gravity. The side plate 14 is provided with a plurality of drainage holes 143 on the side away from the liquid inlet pipe 11. The clean water flowing into the waterproof conveying belt 12 is discharged from the drainage holes 143. The rack 1 is further provided with a water accumulation box for collecting the clean water discharged from the drainage holes 143.

[0055] With reference to Figure 1 and Figure 6The end of the rack 1 away from the liquid inlet pipe 11 is fixedly provided with a support arm 16, the support arm 16 is slidingly connected with a movable block 161 along the length direction, the end of the filter cartridge along the length direction is coaxially fixedly provided with a support shaft, the support shaft passes through the movable block 161 and is rotationally connected with the movable block 161, the movable block 161 is provided with a rotary motor 17, the rotary motor 17 is used for driving the support shaft to rotate. The movable block 161 and the support arm 16 are provided with an elastic element 162, the elastic element 162 is a spring, one end of the spring is fixedly connected with the movable block 161, the other end is fixedly connected with the support arm 16, the elastic element 162 is in a deformed state and applies a pushing force close to the waterproof conveying belt 12 to the movable block 161, so that the filter roller 5 is close to the waterproof conveying belt 12.

[0056] With reference to Figure 1 and Figure 6 The filter roller 5 is hollowly arranged and is provided with a plurality of extrusion openings 51 along the circumference direction, and the filter roller 5 is provided with a filter layer 52 along the circumference direction, when the solid sediment layer passes between the filter roller 5 and the waterproof conveying belt 12, the filter roller 5 extrudes the solid sediment layer, so that the residual water in the solid sediment layer is pressed out, at this time, part of the water passes through the filter layer 52 and the extrusion openings 51 and enters the inside of the filter roller 5, the height of the lower end of the filter roller 5 is lower than the height of the upper end surface of the waterproof conveying belt 12, the clean water enters the filter roller 5 and is gathered at the lower end of the filter roller 5, the filter roller 5 is provided with a water conveying channel 53 along the axial direction and in communication with the extrusion openings 51, and the filter roller 5 is fixedly provided with a water accumulation ring 54 outside the filter roller 5 and in communication with the water conveying channel 53, the water in the extrusion openings 51 flows into the water accumulation ring 54 along the water conveying channel 53 and is gathered in the water accumulation ring 54, which reduces the probability that the water extruded by the filter roller 5 mixes with the solid sediment layer again.

[0057] The working principle of the mine water treatment device is as follows: the water baffle 13 and the side plate 14 cooperate above the waterproof conveying belt 12 to form a settling part, the wastewater mixed with the flocculating agent enters the settling part and flows under the driving of the waterproof conveying belt 12, the circulating water baffle 13 cooperates to separate the wastewater moving along the settling part, so that the wastewater is settled in the independent settling area and is not disturbed by the remaining flowing wastewater. After the settling is completed, the clear water in the clear water layer is sucked through the cooperation of the drain pipe 41 and the hose 44 to complete a drainage operation, when the clear water layer is discharged, the solid settling layer is separated from the water baffle 2, at this time, the mud separating plate divides the water collecting groove on the solid settling layer, so that the clear water in the solid settling layer is collected, and the clear water in the water collecting groove is sucked through the water suction pipe 19 to complete the second drainage. The solid settling layer is divided in the transverse direction through the push rod 82, so that the water collecting groove discharges the residual clear water to the side edge position of the waterproof conveying belt 12 through the drain groove and the drain hole 143, at this time, the third drainage is completed, finally, the solid settling layer is extruded through the cooperation of the filter press roller 5 and the waterproof conveying belt 12, and then the residual moisture is pressed out, the fourth drainage is completed, and in the settling process of the wastewater, it is not necessary to stop and wait for the wastewater to settle, which is beneficial to improve the working efficiency of the wastewater treatment process.
