The compression washer 2 is used to block the shaft sleeve portion of the uppermost medium disk 002 from above. Two locking nuts A3 are also connected to the externally threaded shaft portion 103 of the connecting shaft 1 above the compression washer 2 via external threads A. The lock nuts A3, compression washer 2, and the position-limiting connection seat 101 of the connecting shaft 1 effectively and stably secure each medium disk 002 to the connecting shaft 1.

[0034] The outer periphery of the pressing head 5 is provided with external threads B, and the pressing head 5 is connected with the positioning sleeve A 4 through the external threads B. The outer periphery of the positioning sleeve A 4 is uniformly provided with one end of two positioning handles 7. The inner side of the sorting cylinder body 001 is provided with two positioning seats 6 near the upper end opening of the sorting cylinder body 001. Each positioning seat 6 is provided with a positioning groove 601. The other end of each positioning handle 7 is respectively clamped in the positioning groove 601 of the corresponding positioning seat 6. The bottom end of the pressing head 5 is used to directly abut against the upper end of the extension shaft part 104 of the connecting shaft 1. By placing the pressing head 5 connected with the positioning sleeve A 4 through threads above the extension shaft part 104 of the connecting shaft 1, and by rotating the pressing head 5 downward after clamping each positioning handle 7 in the corresponding positioning groove 601, the bottom end of the pressing head 5 directly abuts against the upper end of the extension shaft part 104 of the connecting shaft 1, which can effectively ensure the pressing of the extension shaft part 104 of the connecting shaft 1, and further ensure the stability of the whole formed by the connecting shaft 1 and the medium disc 002 in the sorting cylinder body 001, thereby avoiding large noise in the vibration state of the dry powder iron remover, effectively avoiding the phenomenon that the preset limit point cannot be reached due to errors such as the tailor-welding of the sorting cylinder body 001, the machining of the connecting shaft 1, and the assembly gap of the medium disc 002, and not being limited by the limit point, and the manufacturing and assembly cost is relatively low, and the applicability is high.

[0035] Specifically, in the embodiment, the external threaded shaft part 103 of the connecting shaft 1 is further connected with a positioning sleeve B 8 through external threads A. The outer periphery of the positioning sleeve B 8 is uniformly provided with one end of two lifting handles 9. The positioning sleeve B 8 is located on the upper side of the whole of the locking nut A 3. The positioning sleeve B 8 can further ensure the pressing of the medium disc 002. By providing the lifting handles 9 on the positioning sleeve B 8, the medium disc 002 and the connecting shaft 1 pressed on the connecting shaft 1 can be lifted and moved as a whole.

[0036] Specifically, in the embodiment, the pressing head 5 is further connected with a locking nut B 10 through external threads B. The locking nut B 10 is located on the upper side of the positioning sleeve A 4. The upper end of the extension shaft part 104 of the connecting shaft 1 is conical. The bottom end of the pressing head 5 is provided with a pressing groove 501 matching the upper end of the extension shaft part 104 of the connecting shaft 1, which can further ensure the reliable pressing of the extension shaft part 104 of the connecting shaft 1 by the pressing head 5 connected with the positioning sleeve A 4 through threads. In the embodiment, the openings of the positioning grooves 601 on all the positioning seats 6 are downward, which is also used to ensure that the positioning seats 6 form a reliable downward pressing force on the pressing head 5 through the positioning handles 7.

[0037] Specifically, as shown in FIG. 1, Figure 6As shown, the top surface of the connecting shaft support 003 in this embodiment is upwardly provided with a clamping protrusion 0031, and the bottom surface of the limiting connecting seat portion 101 of the connecting shaft 1 is provided with a limiting clamping groove 1011 matched with the clamping protrusion 0031. The clamping protrusion 0031 is in the shape of a "one" character, which can effectively prevent the connecting shaft 1 from rotating around its axis after the limiting connecting seat portion 101 of the connecting shaft 1 is inserted into the connecting shaft support 003. The top surface of the clamping protrusion 0031 is further provided with a conical clamping boss 0032, and the inner bottom surface of the limiting clamping groove 1011 is recessed to form a clamping notch 1012 matched with the clamping boss 0032. Through the matching arrangement of the conical clamping boss 0032 and the clamping notch 1012, the friction force after the limiting connecting seat portion 101 of the connecting shaft 1 is inserted into the connecting shaft support 003 can be further increased, the upper and lower limits are completed, and the pressing effect is further improved. Through the above arrangement, after the pressing head 5, the positioning sleeve B 8, the locking nut A 3 and the pressing gasket 2 are removed, each medium disc 002 sleeved on the connecting shaft 1 can be effectively taken out from the sorting cylinder body 001 one by one and individually, and the cleaning effect is facilitated, without the need to completely take out the medium disc 002 and the connecting shaft 1 from the sorting cylinder body 001 as a whole. At this time, the limiting connecting seat portion 101 of the connecting shaft 1 and the connecting shaft support 003 can be kept in stable and close connection, effectively avoiding the installation difficulty caused by the multiple limiting visual blind spots, and also reducing the difficulty and cost of processing and manufacturing.
