The inner cavity is rotatably connected to a second rotating rod 8, and the second rotating rod 8 cooperates with the rotating mechanism 6. A stirring rod 9 is fixed on the surface of the first rotating rod 7 and the second rotating rod 8. With the cooperation of the stepping motor 5 and the rotating mechanism 6, the first rotating rod 7 can drive the stirring rod 9 on the surface of the first rotating rod 7 to rotate, and at the same time, the second rotating rod 8 drives the stirring rod 9 on the surface of the second rotating rod 8 to rotate in the opposite direction, so that the stirring rod 9 can mix the coal slurry water and the flocculant more comprehensively, and speed up the rate of the device to treat the coal slurry water, thereby increasing the practicality of the device. The output shaft of the stepping motor 5 is connected to the rotating shaft 10 through two belt pulleys and a timing belt drive, and the processing The surface of the barrel 2 is bolted with a fixing sleeve 11, and the inner cavity of the fixing sleeve 11 is rotatably connected to the surface of the rotating shaft 10. Under the action of the fixing sleeve 11, the rotating shaft 10 is effectively prevented from positional displacement during operation, which increases the stability of the rotating shaft 10 and thus increases the stability of the device. The bottom of the rotating shaft 10 is transmission-connected with a connecting rod 12, and the other end of the connecting rod 12 is rotatably connected to the bottom of the inner cavity of the processing barrel 2. With the cooperation of the stepping motor 5 and the rotating shaft 10, the connecting rod 12 can be rotated in the inner cavity of the processing barrel 2. A rubber pad 13 is provided at the bottom of the surface of the processing barrel 2. The inner cavity of the rubber pad 13 is rotatably connected to the surface of the connecting rod 12. When used, it can effectively prevent the water from flowing out of the gap of the connecting rod 12 when it is working, thereby increasing the stability of the device. The inner cavity of the processing barrel 2 is provided with a vibration mechanism 14, and the bottom of the inner cavity of the processing barrel 2 is provided with a filter screen 15. The filter screen 15 can filter the treated coal slime water, so that the solid objects produced by the mixture of flocculant and coal water remain on the top of the filter screen 15, and the treated water falls into the bottom of the filter screen 15 and is discharged through the drain port 4. Under the action of the vibration mechanism 14, the solid objects on the top of the filter screen 15 can be vibrated, which effectively prevents the situation where too many solid objects cause the water source to be discharged slowly, thereby increasing the drainage rate of the device.

[0023] The rotating mechanism 6 includes a first bevel gear 61, one side of the first bevel gear 61 is fixedly connected to the output shaft of the stepper motor 5, the top of the first bevel gear 61 is meshed with the second bevel gear 62, the bottom of the first bevel gear 61 is meshed with the third bevel gear 63, the inner cavity of the second bevel gear 62 is fixedly connected to the surface of the second rotating rod 8, and the bottom of the third bevel gear 63 is fixedly connected to the top of the first rotating rod 7. Under the action of the stepper motor 5, the first bevel gear 61 can drive the second bevel gear 62 and the third bevel gear 63 to rotate in opposite directions at the same time, so that the stirring rod 9 on the surface of the first rotating rod 7 and the stirring rod 9 on the surface of the second rotating rod 8 rotate in opposite directions at the same time, so that the stirring rod 9 can mix the flocculant and coal water more comprehensively, and speed up the rate of coal water treatment of the device, thereby increasing the practicality of the device.

[0024] The vibration mechanism 14 includes a protrusion 141, the inner cavity of the protrusion 141 is fixedly connected to the surface of the connecting rod 12, a tension spring 142 is fixed to the bottom of the inner cavity of the processing barrel 2, and a movable shell 143 is fixed to the top of the tension spring 142.

Under the cooperation of the rotating shaft 10 and the connecting rod 12, the protrusion 141 can be rotated at the bottom of the movable shell 143. When the longer part of the surface of the protrusion 141 contacts the movable shell 143, the movable shell 143 drives the filter 15 to move upward, and at the same time the tension spring 142 is stretched upward. When the connecting rod 12 When the longer part of the surface of the driving protrusion 141 is intertwined with the bottom of the movable shell 143, the movable shell 143 can drive the filter screen 15 to move downward under the action of the rebound of the tension spring 142, thereby achieving the vibration effect of the filter screen 15, thereby accelerating the rate at which the device discharges water. A guide rod 16 is fixed to the bottom of the inner cavity of the base 1, and the surface of the guide rod 16 is slidably connected to the inner cavity of the movable shell 143.

[0025] Working principle: First, the staff adds the coal slime water and flocculant to be treated into the interior of the treatment barrel 2 through the feeding port 3. When the device treats the coal slime water, with the cooperation of the stepping motor 5 and the first bevel gear 61, the second bevel gear 62 can drive the stirring rod 9 on the surface of the second rotating rod 8 to rotate, and at the same time, the third bevel gear 63 drives the stirring rod 9 on the surface of the first rotating rod 7 to rotate in the opposite direction, so that the flocculant and the coal slime water are fully mixed, and the solid matter produced by the mixture of the flocculant and the coal slime water falls down to the top of the filter screen 15. At the same time, when the staff discharges the water source, the stepping motor 5 drives the rotating shaft 10 through two belt pulleys and a timing belt. The rotating shaft 10 drives the connecting rod 12 to rotate, and the connecting rod 12 drives the protrusions 141 on both sides to rotate. When the longer part of the surface of the protrusion 141 corresponds to the bottom of the movable shell 143, the movable shell 143 drives the filter screen 15 to move upward, and the tension spring 142 is stretched. When the connecting rod 12 drives the longer part of the surface of the protrusion 141 to intersect with the bottom of the movable shell 143, under the action of the rebound of the tension spring 142, the movable shell 143 can drive the filter screen 15 to move downward, thereby achieving the vibration effect of the filter screen 15, thereby accelerating the drainage rate of the device through the drain port 4, and then the staff can take out the solid matter.
