[0002] Coal mine solid waste resource utilization refers to the process of recycling, reusing, or harmlessly treating solid waste (such as coal gangue and slag) generated during coal mining through a series of technological means, transforming it into valuable resources, reducing environmental pollution, and promoting sustainable resource development. Coal mine solid waste is generated in large quantities, and its direct dumping or improper disposal can easily lead to a series of environmental problems such as soil pollution, water pollution, and air pollution. Therefore, how to effectively utilize coal mine solid waste resources to both reduce waste volume and achieve resource recovery, while minimizing negative impacts on the ecological environment, has become a key issue that urgently needs to be addressed in the coal mining industry and the field of environmental protection. While some technological achievements exist in solid waste resource utilization, certain technological bottlenecks remain in achieving efficient, low-cost, and environmentally friendly utilization methods.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model embodiment provides a screening device for the resource utilization of coal mine solid waste, including a base 1. The device is characterized by: a filter assembly 8 being provided on the top of the base 1; the filter assembly 8 including a U-shaped mounting seat 801, the U-shaped mounting seat 801 being fixedly installed on the top of the base 1; a filter screen 802 being slidably connected to the inner side of the U-shaped mounting seat 801; a fixing plate 804 being fixedly installed on the right side of the U-shaped mounting seat 801; a turntable 805 being movably connected to the top of the fixing plate 804 via a rotating shaft; a connecting rod 806 being movably connected to the top of the turntable 805; and a guide hopper 803 being fixedly installed on the left side of the U-shaped mounting seat 801.

[0029] By starting the second motor 807, the output end of the second motor 807 drives the turntable 805 to rotate. While the turntable 805 rotates, it drives the surface connecting rod 806 to perform a circular motion. The other end of the connecting rod 806 is movably connected to the bottom of the filter screen 802, so that the filter screen 802 can move left and right in the U-shaped mounting base 801 to finely screen the surface filter material and avoid filter screen clogging.

[0030] Example 2

[0031] like Figure 1-6 As shown, in one embodiment, a second motor 807 is fixedly installed at the bottom of the fixed plate 804. The output end of the second motor 807 is fixedly connected to the turntable 805. A circulation assembly 9 is provided at the top of the base 1. The circulation assembly 9 includes a circulation box 901, which is fixedly installed at the top of the base 1. A spiral blade 902 is movably connected to the inner side of the circulation box 901 via a rotating shaft. A feed inlet 903 is provided on the right side of the circulation box 901. The surface of the feed inlet 903 is fixedly connected to the left side of the guide hopper 803. A circulation outlet 905 is connected to the top of the right side of the circulation box 901. A third motor 904 is fixedly installed on the base 1. The output end of the third motor 904 is fixedly connected to the spiral blade 902. Support columns 2 are fixedly installed on the front and rear sides of the top of the base 1. A crushing box 3 is fixedly installed on the inner side of the support column 2. The inner cavity of the crushing box 3 is movably connected to the first crushing roller 4 through a rotating shaft.

The output end of the first motor 6 is fixedly connected to the second crushing roller 5. A hopper 7 is connected to the bottom of the crushing box 3.

[0032] Larger materials filtered through the surface of the filter screen 802 fall into the circulation box 901 through the guide hopper 803 and the feed inlet 903. By starting the third motor 904, the output end of the third motor 904 drives the spiral blades 902 to rotate, so that the material flows from bottom to top along the spiral blades 902. Larger materials fall into the inner side of the crushing box 3 through the circulation outlet 905, so that the material is repeatedly crushed.

[0033] In operation, this invention works as follows: First, the material to be screened is poured into the crushing box 3. The first motor 6 is started, and its output drives the second crushing roller 5 to rotate. The second crushing roller 5, by engaging with the first crushing roller 4, crushes the material in the crushing box 3. The crushed material falls through the hopper 7 onto the surface of the filter screen 802. Then, the second motor 807 is started, and its output drives the turntable 805 to rotate. Simultaneously, the turntable 805 rotates, causing the surface connecting rod 806 to move in a circular motion. The other end of the connecting rod 806 connects to the filter screen... The bottom movable connection of 802 allows the filter screen 802 to move left and right within the U-shaped mounting base 801, finely screening the surface filter material while preventing filter screen clogging. Larger materials filtered through the surface of the filter screen 802 fall into the circulation box 901 through the guide hopper 803 and the feed inlet 903. By starting the third motor 904, the output end of the third motor 904 drives the spiral blades 902 to rotate, and finally the material is made to flow from bottom to top along the spiral blades 902. Larger materials fall into the inner side of the crushing box 3 through the circulation outlet 905, so that the material is repeatedly crushed.
