Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a coal mine wastewater treatment device. Background Art

[0002] A large amount of wastewater is generated during the mining process of coal mines. In order to reduce pollution to the environment, these wastewaters need to be treated before discharge. Usually, specific chemical reagents are added to the wastewater to purify the wastewater. For example, the patent with application number 202220264126.X proposes a wastewater treatment device for coal mine mining, including an outer shell, which includes a flocculation tank and a filter tank. Slag discharge ports are provided on the front and rear inner walls of the flocculation tank, and a feeding port is provided on the top inner wall of the flocculation tank. A feeding pipe is fixedly connected to the inner wall of the feeding port, and water outlets are provided on the front and rear inner walls of the filter tank. A regulating valve is provided inside the slag discharge port. The coal mine adopts a wastewater treatment device. By setting up a diversion table, the wastewater enters the flocculation tank and flows around under the action of the diversion table, so that the impurities produced by the reaction of the wastewater and the flocculant flow to the slag discharge port under the drive of the wastewater. A regulating valve is set inside the slag discharge port so that the impurities accumulate outside the slag discharge port to avoid the impurities in the flocculation tank from scattering and affecting the efficiency of the flocculation work, thereby ensuring the wastewater treatment efficiency of the device and improving the working efficiency of the device.

[0003] Before treating the wastewater, it needs to be filtered to screen out large impurities in the wastewater. Coal mine wastewater contains a lot of coal slag, and the filter inside the wastewater treatment device needs to be frequently taken out for cleaning and replacement to ensure that the filter is not blocked. Frequent cleaning of the filter is cumbersome and will also reduce the wastewater treatment efficiency. Therefore, we have made improvements to this and proposed a coal mine wastewater treatment device. Utility Model Content

[0023] like Figure 3 As shown, a slot 201 is provided on one end surface of each mounting plate 2, and buckles 301 are installed in the middle of both end surfaces of the filter screen 3, and each buckle 301 is movably arranged inside the slot 201 at a corresponding position.

[0024] Through the clamping fit between the buckle 301 and the clamping slot 201 , the filter 3 can be movably installed between the two mounting plates 2 , which is convenient for disassembly and replacement of the filter 3 .

[0025] like Figure 4 As shown, baffles 101 are installed on both inner walls of the shell 1 , through grooves 102 are penetrated on both sides of the shell 1 and on one side of the baffle 101 , and guiding slopes 103 are provided on the bottom of the through groove 102 and the upper surface of the baffle 101 .

[0026] The position of the filter screen 3 can be limited by the baffle 101. The surfaces of the baffle 101 and the through groove 102 are both provided with guiding slopes 103, which can play a guiding role in the falling process of the coal slag, so that the coal slag can fall into the inside of the aggregate trough 5 faster, which is more convenient during use.

[0027] like Figure 3 As shown, the driving mechanism 4 includes a fixing frame 401, which is mounted on one side of the outer surface of the shell 1, a servo motor 402 is mounted on one end surface of the fixing frame 401, a first rotating rod 403 is mounted on the output end of the servo motor 402, one end of the first rotating rod 403 is rotatably mounted on one side surface of the shell 1, a first gear 404 is fixedly mounted on the rod body of the first rotating rod 403, a second rotating rod 405 is rotatably mounted on one side of the inner side of the fixing frame 401, one end of the second rotating rod 405 passes through the shell 1 and is fixedly connected to the middle part of one end surface of one of the mounting plates 2, one end of the other mounting plate 2 is rotatably mounted on one side of the inner side of the shell 1, a second gear 406 is fixedly mounted on the rod body of the second rotating rod 405 located on the outer side of the shell 1, and the second gear 406 and the first gear 404 are meshed with each other.

[0028] Through the meshing transmission between the first gear 404 and the second gear 406, the filter screen 3 can be controlled to rotate under the drive of the servo motor 402, so that the coal slag remaining on the surface of the filter screen 3 can fall into the inside of the aggregate trough 5, which can reduce the accumulation of debris on the surface of the filter screen 3 and avoid blockage.

[0029] The working principle of this coal mine wastewater treatment device:

[0030] When in use, waste water is added into the interior through the top of the shell 1, and the large volume of coal slag in the waste water is filtered through the filter screen 3, and then the treatment reagent is added to react with the waste water to treat the waste water. After the treatment is completed, the waste water is discharged through the outlet pipe 6. The first rotating rod 403 is driven to rotate by the servo motor 402. Under the meshing action between the first gear 404 and the second gear 406, the rotation of the first rotating rod 403 can drive the second rotating rod 405 to rotate, thereby driving the mounting plate 2 to rotate with the second rotating rod 405 as the axis, so that the filter screen 3 Following the rotation, baffles 101 are provided on both sides of the shell 1 to limit the inclination angle of the filter 3. The servo motor 402 controls the reciprocating rotation of the first rotating rod 403 to control the filter 3 inside the shell 1 to reciprocate left and right tilting.

The operation is convenient and can effectively improve the wastewater treatment efficiency.
