[0031] Reference Figure 1~Figure 2 The embodiment of the utility model proposes an experimental slag tailings mixing device, including an inner shell 1, the inner shell 1 has a first material dropping channel 101, the middle shell 2 is arranged outside the inner shell 1, and a second material dropping channel 201 is formed between the inner shell 1, the outer shell 3 is arranged outside the middle shell 2, and a third material dropping channel 301 is formed between the middle shell 2, and the screening element 4 is constructed as a stepped truncated cone type, and the screening element 4 has a first screening element 401, a second screening element 402 and a third screening element 403, and the first screening element 401, the second screening element 402 and the third screening element 403. The second screening element 402 and the third screening element 403 are respectively located on different steps on the stepped truncated platform, the first screening element 401 leads to the first blanking channel 101, the second screening element 402 leads to the second blanking channel 201, and the third screening element 403 leads to the third blanking channel 301. The first screening element 401, the second screening element 402 and the third screening element 403 all have screening holes 404, and the diameters of the screening holes 404 on the first screening element 401, the second screening element 402 and the third screening element 403 increase successively.

[0032] In this embodiment, considering that the slag tailings are of different shapes and sizes and cannot be fully and evenly mixed with soil, sand, etc., this solution is designed with a stepped truncated cone type screening element 4, each screening element 4 has a screening hole 404, and the diameters of the screening holes 404 on the first screening element 401, the second screening element 402 and the third sieve are increased successively, so that the finer slag passes through the screening holes 404 on the first screening element 401 and falls into the first blanking channel 101, and the coarser slag passes through the screening holes 404 on the second screening element 402 and falls into the second blanking channel 201 for processing, and the remaining slag will pass through the third screening element 403 and fall into the third blanking channel 301 for processing, thereby realizing the distinction and separate processing of slag of different sizes, and being able to process the slag to similar sizes more efficiently and conveniently. The inner shell part 1, the middle shell part 2 and the outer shell part 3 form a blanking channel between each shell part, and different processing mechanisms can be arranged between the individual blanking channels to achieve more targeted individual processing.

[0033] Furthermore, it also includes a main shaft 5 rotatably set on the inner shell part 1, a first grinding disc 9 is set on the main shaft 5 and located in the second blanking channel 201, a second grinding disc 10 is set on the inner wall of the middle shell part 2 and located in the second blanking channel 201, and a fine grinding space 901 is formed between the first grinding disc 9 and the second grinding disc 10.

[0034] In this embodiment, a main shaft 5 is provided as the power source of the whole device. In the second blanking channel 201, medium-sized slag is processed by a grinding method, and a first grinding disc 9 and a second grinding disc 10 are provided. The first grinding disc 9 is fixedly provided, and the first grinding disc 9 is rotatably provided relative to the second grinding disc 10. Under the action of the first grinding disc 9 and the second grinding disc 10, the medium-sized slag is processed into finer-sized slag, thereby achieving the unification of the size of the slag after processing.

[0035] Furthermore, the inner wall of the outer shell 3 has a reduced diameter portion 302 , and further includes a grinding piece 6 disposed on the main shaft 5 , and a rough grinding gap 601 is formed between the grinding piece 6 and the reduced diameter portion 302 .

[0036] In this embodiment, a necking portion is provided on the inner wall of the outer shell portion 3, and a grinding member 6 is provided on the main shaft 5. The necking portion and the grinding member 6 are both arranged in the third blanking channel 301. The size of the coarse grinding gap 601 gradually decreases downward, and large pieces of slag are continuously crushed and processed, and smaller slag slides out of the coarse grinding gap 601. This design processes large pieces of slag and realizes preliminary coarse grinding of the large pieces of slag, making it easier to carry out subsequent fine grinding processing.

[0037] Furthermore, the reduced diameter portion 302 has a first edge portion 303 , and the grinding member 6 has a second edge portion 602 . The first edge portion 303 and the second edge portion 602 are both arranged in a plurality of circles.

[0038] In this embodiment, the neck portion is provided with a first edge portion 303, and the grinding piece 6 has a second edge portion 602. During the relative rotation of the grinding piece 6 and the neck portion, the first edge portion 303 and the second edge portion 602 produce an extrusion and crushing effect on large pieces of slag. The setting of the first edge portion 303 and the second edge portion 602 makes the coarse crushing process more convenient and the crushing efficiency is higher.

[0039] Furthermore, the second blanking channel 201 has a side feed port 202 , and the reduced diameter portion 302 has a frustum inlet 304 and a frustum outlet 305 , and the frustum outlet 305 leads to the side feed port 202 .

[0040] In this embodiment, the slag that has undergone coarse crushing and become smaller in the third blanking channel 301 enters the second blanking channel 201 through the cone outlet 305 and the side feed port 202 of the second blanking channel 201, and is finely ground in the second blanking channel 201, thereby achieving unified treatment of slag that has been treated separately by multiple processes, and finally obtaining slag of uniform size, thereby avoiding the excessive working pressure of the device when different sizes are treated uniformly or the mutual influence between slags of different sizes.

[0041] Furthermore, the first screening element 401 has a first annular stopper 405, the second screening element 402 has a second annular stopper 406, and the third screening element 403 has a third annular stopper 407. The first annular stopper 405, the second annular stopper 406 and the third annular stopper 407 are all located at the top of the inner shell portion 1, the middle shell portion 2 and the outer shell portion 3.

[0042] In this embodiment, an annular baffle is provided on the first screening element 401, the second screening element 402 and the third screening element 403. The height of the annular baffle is the same as the diameter of the screening hole 404 of the corresponding screening element 4, so that the slag that cannot be screened is discharged to the next screening element 4. At the same time, the annular baffle is provided so that the slag can be fully dropped into the corresponding screening hole 404, preventing the corresponding size of slag that has not completely dropped from falling into the next dropping channel too much, thereby affecting the processing process in the next dropping channel.

[0043] Furthermore, the third annular stopper 407 has a connecting portion 408 , and the main shaft 5 is rotatably disposed on the connecting portion 408 .

[0044] In this embodiment, the connecting portion 408 on the third annular stopper is used to provide a setting position for the upper end of the main shaft 5, so that the rotation of the main shaft 5 is more stable.

[0045] Furthermore, it also includes a scraper member 7 , which is arranged on the main shaft 5 and is arranged to contact and slide with the screening member 4 .

[0046] In this embodiment, a scraper member 7 is provided on the main shaft 5, and the scraper member 7 can stir the slag on each screening member 4 so that the slag of corresponding size can fully fall into the corresponding material dropping space. At the same time, it can also prevent the slag blocked by the annular baffle from accumulating on the screening member 4 and causing a part of it to be unable to be discharged normally.

[0047] Furthermore, a connecting member 8 is included, and two ends of the connecting member 8 are respectively connected to the main shaft 5 and the first grinding disc 9, so as to drive the first grinding disc 9 to rotate.

[0048] In this embodiment, the first grinding disc 9 and the main shaft 5 are connected in series using a connecting piece 8, which simplifies the power in the device, makes the overall device structure more compact, and improves the processing efficiency.

[0049] Furthermore, the middle shell portion 2 has a first middle shell portion 203 and a second middle shell portion 204 , and a side feed port 202 is formed between the first middle shell portion 203 and the second middle shell portion 204 .

[0050] In this embodiment, the middle shell part 2 is split into the first middle shell part 203 and the second middle shell part 204 to form the side feed port 202, thereby realizing the transfer of materials after being processed in different blanking channels.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
