[0004] The existing technology has the following shortcomings: When extracting the required components from coal-based solid waste, the existing leaching device cannot fully mix the coal-based solid waste powder with the solvent, so the required components in the coal-based solid waste cannot be fully extracted. This also affects the leaching efficiency. In addition, coal-based solid waste residue is easy to appear on the inner wall of the device, which affects the cleanliness of the device and will affect the next leaching operation. Utility Model Content

[0027] This utility model provides, for example Figure 1 The coal-based solid waste pretreatment leaching device shown includes a device body 1, and further includes:

[0028] The mixing mechanism 2 is located inside the main body 1 and is used to mix coal-based solid waste and solvent.

[0029] To ensure thorough mixing of coal-based solid waste and solvent, such as Figure 1-3 and Figure 5 As shown, the mixing mechanism 2 includes a hydraulic cylinder 201, which is located on the top of the device body 1. The piston rod of the hydraulic cylinder 201 is fixedly mounted on a fixed base 202. A servo motor 203 is fixedly mounted inside the fixed base 202. The output shaft of the servo motor 203 is fixedly sleeved with a mounting base 204. Multiple stirring rods 205 are fixedly mounted on the outside of the mounting base 204. A cleaning ring 206 is fixedly mounted on the outside of the multiple stirring rods 205. The servo motor 203 causes the stirring rods 205 to rotate, so that they can stir and mix the coal-based solid waste and the solvent. At the same time, the hydraulic cylinder 201 can adjust the height of the stirring rods 205, so that the coal-based solid waste and the solvent can be fully mixed, thereby improving the leaching efficiency.

[0030] In order to facilitate the extraction operation of the device body 1, such as Figure 1-2 and Figure 4 As shown, the device body 1 includes a fixed outer shell 101, a cover plate 102 is provided on the top of the fixed outer shell 101, and a plurality of connecting bolts 103 are provided between the fixed outer shell 101 and the cover plate 102 and are fixedly connected by the connecting bolts 103. A feed pipe 104 is fixedly installed on the inner wall of one end of the top of the cover plate 102, and an exhaust pipe 105 is fixedly installed on the inner wall of the other end of the top of the cover plate 102. A liquid inlet pipe 106 is fixedly installed on the top of one end of the outer wall of the fixed outer shell 101, and a discharge pipe 107 is fixedly installed on the inner wall of the bottom of the fixed outer shell 101. Coal-based solid waste and solvent can be added into the fixed outer shell 101 through the feed pipe 104 and the liquid inlet pipe 106, and the waste gas generated during the leaching process can be discharged through the exhaust pipe 105.

[0031] To facilitate the recycling of solvents, such as Figure 2 and Figure 4 As shown, a return pipe 108 is fixedly installed on the outer wall of the fixed housing 101 away from the liquid inlet pipe 106. The return pipe 108 has three ports. Two of the ports of the return pipe 108 are respectively located at the top and bottom of the fixed housing 101 away from the liquid inlet pipe 106. The other port of the return pipe 108 is connected to the outside. Filter plates 109 are fixedly installed on the inner walls of the two ports of the return pipe 108 near the fixed housing 101. A valve is provided at the port of the return pipe 108 away from the fixed housing 101. The solvent at the top of the fixed housing 101 can be returned to the bottom of the fixed housing 101 through the return pipe 108. At the same time, the solvent can be conveniently discharged from the inside of the fixed housing 101 through the port at the bottom of the return pipe 108.

[0032] To ensure that the stirring rod 205 and the cleaning ring 206 can stably mix and clean coal-based solid waste and solvents, such as Figure 2-5As shown, the top of the cover plate 102 is fixedly connected to the hydraulic cylinder 201. The diameter of the fixed seat 202 is the same as the diameter of the mounting seat 204. There are six stirring rods 205, which are arranged in a ring at equal intervals. All six stirring rods 205 are set with an inclined structure. The outer diameter of the cleaning ring 206 is the same as the inner diameter of the fixed shell 101. The multiple stirring rods 205 with the inclined structure can easily stir and mix coal-based solid waste and solvent. At the same time, the cleaning ring 206 can clean the inner wall of the fixed shell 101, which can prevent coal-based solid waste from adhering to the inner wall of the fixed shell 101 and affecting its cleanliness.

[0033] During the leaching operation of coal-based solid waste, pulverized coal-based solid waste powder can be added into the fixed shell 101 through the feed pipe 104, and the required solvent can be added into the fixed shell 101 through the liquid inlet pipe 106. The servo motor 203 then rotates the mounting base 204, causing the stirring rod 205 to mix the coal-based solid waste and solvent. Simultaneously, the hydraulic cylinder 201 adjusts the height of the fixed base 202, thereby adjusting the height of the stirring rod 205. This allows the stirring rod 205 to mix the coal-based solid waste and solvent at different heights inside the fixed shell 101. Furthermore, the rotation and raising / lowering of the stirring rod 205 drives the cleaning ring 206 to clean the inner wall of the fixed shell 101. This method avoids coal-based solid waste adhering to the inner wall of the fixed shell 101, affecting its cleanliness. The waste gas generated during the leaching process can be discharged from the inside of the fixed shell 101 through the exhaust pipe 105. At the same time, the solvent at the top of the inner side of the fixed shell 101 can be returned to the bottom of the inner side of the fixed shell 101 through the return pipe 108, so that the solvent can be fully mixed with the coal-based solid waste. Moreover, the solvent can be conveniently discharged from the inside of the fixed shell 101 through the port at the bottom of the return pipe 108. At the same time, the deposited coal-based solid waste can be discharged from the inside of the fixed shell 101 through the discharge pipe 107, thereby improving the leaching efficiency of coal-based solid waste. This embodiment specifically solves the problem in the prior art that insufficient mixing of coal-based solid waste and solvent and the easy presence of residue on the inner wall of the device will affect the leaching efficiency.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
