Description

Technical Field

[0001] This invention relates to the field of coal mine wastewater reprocessing technology, specifically to a coal mine wastewater reprocessing device. Background Technology

[0002] Coal mine wastewater is wastewater formed during the conversion, product recycling, and processing of coal. In addition to substances present in coal slag, coal mine wastewater may also contain intermediate products of coal conversion, as well as other chemical substances added during the production process. If it is directly discharged into the outside world, it will pollute the environment.

[0003] Existing coal mine wastewater treatment devices filter coal slag from the wastewater through a filter screen inside the tank to facilitate the recycling of coal slag and the discharge of coal mine water. However, since coal mine wastewater contains some iron-containing impurities, the filter screen in the existing treatment device is limited to filtering coal slag and is not convenient for cleaning iron-containing impurities in the coal mine wastewater. As a result, iron-containing impurities are mixed in the coal mine wastewater and enter the environment along with the sewage discharge, resulting in high iron content in the water in the environment. This makes the water more susceptible to turbidity due to reaction with oxygen in the air.

[0004] Therefore, it is necessary to provide a new coal mine wastewater reprocessing device to solve the above-mentioned technical problems. Summary of the Invention

[0010] To achieve greater stability during the lifting and lowering of the U-shaped frame, the coal mine wastewater reprocessing device provided by this invention preferably includes two vertical blocks fixed to the top of the support block. Each vertical block has an internal movable groove. A second spring is fixedly connected to the top wall of the movable groove.

[0014] This coal mine wastewater retreatment device employs an adsorption mechanism. The magnetic properties of the magnetic columns within a U-shaped frame adsorb iron-containing impurities from the wastewater, causing them to adhere to the surface of the magnetic columns. This prevents iron-containing impurities from entering the environment along with the wastewater, thus protecting the environment. It also solves the problem of existing treatment devices where filters are limited to filtering coal slag and are ineffective at cleaning iron-containing impurities from the wastewater. This prevents iron-containing impurities from mixing within the wastewater and entering the environment with the wastewater, resulting in high iron content in the water and making the water prone to turbidity due to interaction with oxygen in the air.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A schematic diagram of a preferred embodiment of the coal mine wastewater re-treatment device provided by the present invention; Figure 2 This is a side view of the processed box structure of the present invention; Figure 3 This is a schematic diagram of the connection between the housing and the support block in this invention; Figure 4 This is a three-dimensional view of the adsorption mechanism of the present invention; Figure 5 This is a schematic diagram of the connection between the U-shaped frame and the circular plate of the present invention. A coal mine wastewater retreatment device includes a treatment box 1. Two sets of support legs 2 are fixed at the bottom of the treatment box 1 and are symmetrically distributed on the left and right. A filter screen 3 is installed inside the treatment box 1. A water inlet pipe 4 is connected to the top of one side of the treatment box 1, and a water outlet pipe 5 is connected to the bottom of the other side of the treatment box 1. An adsorption mechanism for removing iron-containing impurities is installed at the top of the treatment box 1. The adsorption mechanism includes a magnetic column 101. Two circular plates 102 are fixed on the outside of the magnetic column 101 and are symmetrically distributed on the left and right. A U-shaped frame 103 is installed on the outside of the magnetic column 101. A bearing seat 104 is fixed at the top of the U-shaped frame 103. A threaded rod 105 is rotatably connected inside the bearing seat 104. A support block 106 is connected to the top of the treatment box 1. A cap 107 is fixedly connected to the top of the support block 106 through a threaded hole 108.

[0023] Through the above technical solution, the support block 106 is placed on top of the treatment box 1, so that the bottom sides of the support block 106 contact the top of the treatment box 1 respectively. Then, the two magnetic columns 101 in the U-shaped frame 103 at the bottom of the support block 106 can adsorb iron-containing impurities in the coal mine wastewater, so that the iron-containing impurities are attached to the surface of the magnetic columns 101. By rotating the cap 107 and the threaded rod 105, and through the cooperation of the threaded rod 105 and the threaded hole 108, the height of the magnetic columns 101 can be adjusted to improve the adsorption efficiency of the magnetic columns 101 for iron-containing impurities in the coal mine wastewater, and prevent iron-containing impurities from entering the environment along with the sewage discharge, thus playing a certain role in environmental protection.

[0024] Reference Figure 2 , Figure 4 and Figure 5The U-shaped frame 103 has a through hole 109 inside, and an assembly rod 110 is installed inside the through hole 109. A baffle 111 is fitted inside the through hole 109 and outside the assembly rod 110. A first spring 112 is installed outside the assembly rod 110. One end of the first spring 112 is fixedly connected to the outer wall of the assembly rod 110, and the other end of the first spring 112 is fixedly connected to the outer wall of one side of the baffle 111. The assembly rod 110 extends out of the outer wall of the through hole 109 and is movably connected to the inner wall of the assembly groove 113 opened on one side of the circular plate 102. A first groove 114 is opened on one side of the assembly rod 110. A pull rod 115 is fixedly connected to the inner wall of one side of the groove 114. By pulling the assembly rod 110 in the through hole 109, one end of the assembly rod 110 is disengaged from the assembly groove 113 and enters the through hole 109. This allows the magnet column 101 to be removed from the U-shaped frame 103 for replacement. This ensures that the magnet column 101's adsorption capacity for iron-containing impurities is reduced during long-term use, thus maintaining its adsorption efficiency. Furthermore, the pull rod 115 in the first groove 114 facilitates the application of tension to the assembly rod 110, making it easier to replace the magnet column 101.

[0025] Reference Figure 1 , Figure 2 and Figure 4 Two vertical blocks 116 are fixed to the top of the support block 106. The vertical blocks 116 have movable grooves 117 inside. A second spring 118 is fixedly connected to the top wall of the movable groove 117. A first limiting plate 119 is fixedly connected to the bottom of the second spring 118. A connecting rod 120 is fixedly connected to the bottom of the first limiting plate 119. The bottom of the connecting rod 120 passes through the vertical blocks 116 and the support block 106 in sequence and is fixedly connected to one side of the top of the U-shaped frame 103. When the U-shaped frame 103 and the magnetic column 101 are adjusting the height inside the box 1, they drive the two connecting rods 120 at the top to move synchronously. The connecting rod 120 drives the first limiting plate 119 in the movable groove 117 to move synchronously, so that the first limiting plate 119 squeezes and stretches the second spring 118. The elasticity of the second spring 118 indirectly makes the height adjustment of the U-shaped frame 103 and the magnetic column 101 more secure and reliable.

[0026] Reference Figure 2 , Figure 3 and Figure 4Two insert blocks 121 are fixed to the bottom of the support block 106. The processing box 1 is inserted into the outer wall of the insert block 121 through the slot 122. A second groove 123 is provided on one side of the insert block 121. Two fixing rods 124 are provided inside the second groove 123. A vertical plate 125 is sleeved on the outside of the fixing rod 124. The outer wall of the vertical plate 125 is fixedly connected to the inner wall of the second groove 123. A second limiting plate 126 is fixedly connected to one end of the fixing rod 124 extending out of the vertical plate 125. A third spring 127 is fixedly connected to the other side of the outer wall of the second limiting plate 126. The other end of the third spring 127 is fixedly connected to the inner wall of one side of the second groove 123. A fixing hole 128 is provided on the side wall of the slot 122 of the processing box 1. The fixing rod 124 extends out of the outer wall of the second groove 123 and is movably connected to the inner wall of the fixing hole 128.

[0027] By pressing the fixing rod 124 on one side of the insert 121, the fixing rod 124 is inserted into the second groove 123, and then the insert 121 is inserted into the slot 122. The elastic action of the third spring 127 causes one end of the fixing rod 124 to enter the fixing hole 128. The insertion 121 can be fixed in the slot 122 by the cooperation of the fixing rod 124 and the fixing hole 128, and then the support block 106 can be fixed on the top of the processing box 1.

[0028] Reference Figure 1 and Figure 2 Inside the treatment chamber 1, on one side of the filter screen 3, there is a stirring shaft 129. Two sets of stirring rods 130 are fixed on the outer wall of the stirring shaft 129 in a symmetrical arrangement. A drive motor 131 is fixed on one side of the bottom of the treatment chamber 1. The stirring shaft 129 extends out of the bottom of the treatment chamber 1 and is fixedly connected to the output end of the drive motor 131. The drive motor 131 is connected to an external power source. The drive motor 131 drives the stirring shaft 129 and stirring rods 130 inside the treatment chamber 1 to rotate. Through the cooperation of the stirring shaft 129 and stirring rods 130, the coal mine wastewater can be stirred and treated. Iron-containing impurities at the bottom of the treatment chamber 1 can be moved upward with the water flow, so that the magnetic column 101 can adsorb the iron-containing impurities.

[0029] The implementation principle of a coal mine wastewater retreatment device according to an embodiment of the present invention is as follows: By using an adsorption mechanism, a support block 106 is placed on top of the treatment box 1, so that the bottom sides of the support block 106 contact the top of the treatment box 1 respectively. Then, the two magnetic columns 101 in the U-shaped frame 103 at the bottom of the support block 106 can adsorb iron-containing impurities in the coal mine wastewater, so that the iron-containing impurities are attached to the surface of the magnetic columns 101. By rotating the cap 107 and the threaded rod 105, and through the cooperation of the threaded rod 105 and the threaded hole 108, the height of the magnetic columns 101 can be adjusted to improve the adsorption efficiency of the magnetic columns 101 for iron-containing impurities in the coal mine wastewater, and prevent iron-containing impurities from entering the environment along with the sewage discharge, thus playing a certain role in protecting the environment.
