When the fastening screw 1 is fastened and installed in the fastening cavity, under the action of the clamping block 4, opposite forces will be simultaneously applied to the inner ring sleeve 2 and the outer ring sleeve 3 to fasten the end of the flushing pipe 5 in the inner ring sleeve 2; more specifically, during assembly, the operator sleeves the inner ring sleeve 2 and the outer ring sleeve 3 on the end of the flushing pipe 5, and then only needs to install the fastening screw 1 in the fastening cavity. At this time, the clamping block 4 will give the outer ring sleeve 3 an outward extrusion force, and at the same time, the clamping block 4 will give the inner ring sleeve 2 an inward extrusion force, so that the flushing pipe 5 is firmly fixed; in summary, by adopting the design of this embodiment, the flushing pipe 5 can be integrated with the overall equipment during the assembly stage, thereby reducing the difficulty of on-site construction.

[0031] According to one embodiment of the present invention, the wall surface of the pressing block 4 facing the fastening cavity has an internal thread that matches the fastening screw 1 .

[0032] According to one embodiment of the present invention, the clamping block 4 has a large head end and a small head end, and the size of the clamping block 4 decreases successively along the direction from the large head end to the small head end; in a preferred embodiment, the clamping block 4 is provided in two, and the two clamping blocks 4 are circumferentially arranged in the outer ring 3, and the two small head ends are arranged opposite to each other; preferably, the two clamping blocks 4 have the same size, and the design of this embodiment can ensure that the force in the axial direction of the flushing tube 5 is stable. In other words, it can ensure that the clamping force of the flushing tube 5 in the axial direction is the same, and there will be no accidental falling off.

[0033] According to one embodiment of the present invention, the pressing block 4 is a wedge-shaped block, the large end of the wedge-shaped block is close to the end of the outer ring 3, and the small end is close to the inside of the outer ring 3. The two wedge-shaped blocks are arranged along the axial direction of the flushing pipe 5, and the small ends of the two wedge-shaped blocks are arranged opposite to each other. Figure 4 shown.

[0034] According to one embodiment of the present invention, in order to further improve the stability of the installation of the flushing pipe 5, as shown in FIG. Figure 3 As shown, the fixing structure of the flushing tube 5 also includes a locking screw 6. The outer periphery of the outer ring sleeve 3 has a mounting position that penetrates inwardly, and the locking screw 6 is tightly connected to the mounting position. Preferably, the locking screw 6 and the mounting position are threadedly connected; during assembly, the operator first sleeves the inner ring sleeve 2 and the outer ring sleeve 3 on the end of the flushing tube 5, and then installs the fastening screw 1 in the fastening cavity. At this time, the clamping block 4 will give the outer ring sleeve 3 an outward extrusion force, and at the same time, the clamping block 4 will give the inner ring sleeve 2 an inward extrusion force. Finally, the locking screw 6 is installed in the mounting position, and the free end of the locking screw 6 applies an inward pressing force to the clamping block 4, thereby further improving the firmness of the flushing tube 5.

[0035] According to one embodiment of the present invention, the installation position corresponds one-to-one to the fastening screw 1, and a through hole matching the installation position is also provided on the clamping block 4, so that the free end of the fastening screw 1 passes through the through hole and abuts against the fastening screw 1, thereby providing inward pressure for the flushing pipe 5 and improving the stability of the flushing pipe 5.

[0036] According to one embodiment of the present invention, the fixing structure of the flushing pipe 5 also includes: a fixed flange 7 and a movable flange 8, the fixed flange 7 and the movable flange 8 are respectively installed at both ends of the flushing pipe 5, and the fixed flange 7 has an installation position for installing the outer ring sleeve 3. During installation, after the outer ring sleeve 3 is installed, the bottom end of the outer ring sleeve 3 is stably installed in the fixed flange 7.

[0037] At the same time, in order to adjust the water outlet nozzle of the flushing pipe 5 to different angles, a plurality of long holes are correspondingly opened in the circumference of the fixed flange 7 and the movable flange 8, so that a suitable water spraying angle can be adjusted according to the actual coal mine on site.

[0038] like Figure 5 As shown, the present application provides a de-mediating screen, specifically comprising: a support frame 9, on which are respectively provided an excitation source 10, a first screening device 11, a coal washing device 12 and a second screening device 13, wherein the excitation source 10 adopts a standard excitation motor or a box-type vibrator, the two are compatible, and maintenance is more convenient, and a linear vibration method is adopted, so that the material running speed is faster and the equipment processing capacity is greater.

[0039] The first screening device 11, the coal washing device 12 and the second screening device 13 are arranged in sequence along the direction of material movement, and are all connected to the excitation source 10, so as to ensure that the first screening device 11, the coal washing device 12 and the second screening device 13 will vibrate synchronously, and form a rapid and continuous shear force to shear the material; preferably, the first screening device 11 is arranged as an arc screen, and the second screening device 13 is arranged as a linear screen, so as to ensure that the material flowing out through the discharge end of the first screening device 11 flows into the coal washing device 12 under the action of free fall for coal washing operation; a flushing pipe 5 is arranged above the second screening device 13, and the end of the flushing pipe 5 is fastened and installed on the support frame 9 by the fixing structure as mentioned above.

[0040] Specifically, the coal washing device 12 includes: a matching spray assembly and a coal washing trough, the concave area of ​​the coal washing trough is located on a side close to the first screening device 11, and both sides of the concave area are set as smooth transition areas, preferably, as Figure 3As shown, the height of the feed end of the coal washing trough is greater than the height of the discharge end, and the spray assembly is tilted in a smooth transition zone close to the feed end, so that the clean water flowing out through the spray assembly can flush the material falling into the coal washing trough, thereby separating the material from the medium attached to its surface, and then flowing into the second screening device 13 through the discharge end; in summary, the use of the above-mentioned structure can enhance the screening effect of the material, effectively improve the medium recovery rate, thereby reducing the medium consumption, while reducing the equipment size and the floor space.
