Description

Technical Field

[0001] This utility model belongs to the technical field of residual electrode autogenous grinding mills, specifically relating to a wear-resistant liner for residual electrode autogenous grinding mills. Background Technology

[0002] Electrolytic aluminum residue, which is the anode part remaining during the aluminum electrolysis process, can expose the pure aluminum inside after being cleaned by an autogenous mill. The processed residue has a variety of important reuse methods.

[0003] Inside the autogenous grinding mill, residual electrodes in the cleaning drum are ground down to remove electrolyte from their surface. Due to prolonged use, the liners inside the mill will wear down. Worn liners need to be removed and replaced to avoid affecting the mill's performance. Replacing entire liners with only partially worn ones is wasteful. Furthermore, installing the liners inside the mill is cumbersome. After each row of liners is installed, workers outside the mill must tighten the nuts promptly to prevent displacement during rotation. The stability of the liners' installation inside the mill also needs improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wear-resistant liner for a residual autogenous grinding mill that can improve upon the aforementioned problems.

[0005] This utility model provides the following technical solution:

[0006] A wear-resistant liner for an autogenous grinding mill includes an autogenous grinding mill cylinder and multiple sets of liner bodies. Each liner body includes multiple liners arranged in a ring on the inner wall of the autogenous grinding mill cylinder. Each liner includes a connecting base plate, a sound insulation layer, and a wear-resistant layer. The sound insulation layer and the wear-resistant layer are snapped into the connecting base plate. Multiple circumferentially distributed fixing blocks are symmetrically arranged at both ends of the autogenous grinding mill cylinder. The fixing blocks are located on one side of the connecting base plate of the liners at both ends. Fixing rods are installed between the fixing blocks at both ends. The connecting base plate passes through the fixing rods. A retaining strip is provided between adjacent fixing rods on the inner wall of the autogenous grinding mill cylinder. A retaining groove is symmetrically arranged at the bottom of the connecting base plate, and the retaining strip is snapped into the retaining groove.

[0007] Furthermore, the liner is arc-shaped, and grooves are symmetrically provided on both sides of the connecting base plate, with the wear-resistant layer and the sound insulation layer snapped into the grooves on both sides.

[0008] Furthermore, both the connecting base plate and the wear-resistant layer are made of rubber, and the sound insulation layer is made of sound insulation cotton.

[0009] Furthermore, the bottom of the wear-resistant layer is coated with an adhesive coating, and the wear-resistant layer is tightly bonded to the sound insulation layer through the adhesive coating, wherein the adhesive coating is an epoxy resin adhesive.

[0010] Furthermore, the top surface of the wear-resistant layer is corrugated, and the cross-section of the clip and the slot is inverted trapezoidal.

[0011] Furthermore, the bottom of the fixing block is arc-shaped.

[0012] Furthermore, fixing holes are provided at both ends of the fixing block.

[0013] Furthermore, the top two ends of the connecting base plate are provided with protruding strips, and the top of the protruding strips is arc-shaped.

[0014] Furthermore, each of the fixing blocks has a top rod groove on the side near the fixing rod, and both ends of the fixing rod are engaged in the top rod groove.

[0015] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0016] 1) The combination of the clips and the slots helps to ensure the stable installation of the liner in the autogenous mill cylinder. The addition of the fixing rod further improves the stability of the liner installation in the cylinder.

[0017] 2) The removable design of the wear-resistant layer avoids the possibility of replacing the entire liner, and the installation and removal of the wear-resistant layer are also relatively convenient;

[0018] 3) The fixing block and fixing rod make the installation of the liner plate more convenient and save installation time. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0026] Combined with appendix Figure 1-4 As shown, a wear-resistant liner for a residual autogenous grinding mill includes an autogenous grinding mill cylinder 1 and multiple sets of liner bodies 13. Each liner body 13 includes multiple liners 8, which are arranged in a ring on the inner wall of the autogenous grinding mill cylinder 1. Each liner 8 includes a connecting base plate 11, a sound insulation layer 7, and a wear-resistant layer 12. The sound insulation layer 7 and the wear-resistant layer 12 are snapped into the connecting base plate 11. Multiple circumferentially distributed fixing blocks 2 are symmetrically arranged at both ends of the autogenous grinding mill cylinder 1. The fixing blocks 2 are located on one side of the connecting base plate 11 of the liners 8 at both ends. Fixing rods 9 are installed between the fixing blocks 2 at both ends. The connecting base plate 11 passes through the fixing rods 9. A retaining strip 3 is arranged between adjacent fixing rods 9 on the inner wall of the autogenous grinding mill cylinder 1. A retaining groove 10 is symmetrically arranged at the bottom of the connecting base plate 11, and the retaining strip 3 is snapped into the retaining groove 10.

[0027] Specifically, the liner 8 is arc-shaped, and the connecting base plate 11 has symmetrical grooves 5 on both sides. The wear-resistant layer 12 and the sound insulation layer 7 are engaged in the grooves 5 on both sides, that is, the wear-resistant layer 12 and the sound insulation layer 7 can be stably installed in the grooves 5 on both sides. In addition, a sleeve hole is provided between the grooves 5 at the bottom of the connecting base plate 11, which is used to connect the base plate 11 to be fitted onto the fixing rod 9.

[0028] Specifically, the connecting base plate 11 and the wear-resistant layer 12 are both made of rubber, which helps to improve the wear resistance of the liner 8. The sound insulation layer 7 is made of sound insulation cotton, which helps to reduce some noise.

[0029] Specifically, the bottom of the wear-resistant layer 12 is coated with an adhesive coating, and the wear-resistant layer 12 is tightly bonded to the sound insulation layer 7 through the adhesive coating. The adhesive coating is an epoxy resin adhesive, which ensures that the wear-resistant layer 12 and the sound insulation layer 7 are firmly bonded.

[0030] Specifically, the top surface of the wear-resistant layer 12 is corrugated, i.e., it is distributed with multiple semi-circular bodies, so as to better resist impact and improve the wear resistance of the wear-resistant layer 12. The cross-section of the clip 3 and the slot 10 is inverted trapezoidal, which helps the clip 3 and the slot 10 to be firmly engaged.

[0031] Specifically, the bottom of the fixing block 2 is arc-shaped so as to better fit the inner wall of the autogenous mill cylinder 1, which is beneficial for subsequent installation and fixing.

[0032] Specifically, the fixing block 2 has fixing holes 6 at both ends, that is, the fixing block 2 is fixedly installed on the inner wall of the autogenous mill cylinder 1 by using fixing holes 6 and fixing bolts.

[0033] Specifically, the connecting base plate 11 has protruding strips 4 at both ends of its top. The top of the protruding strips 4 is arc-shaped, which is consistent with the radius of the semi-circular body on the wear-resistant layer 12, so as to form uniform and continuous ripples, which helps to improve the impact resistance of the liner plate 8.

[0034] Specifically, each of the fixing blocks 2 has a top rod groove on the side near the fixing rod 9, and both ends of the fixing rod 9 are engaged in the top rod groove, which helps to stabilize the installation of the fixing rod 9.

[0035] The following describes the specific installation process for wear-resistant liners:

[0036] Multiple fixing blocks 2 at one end are fixed to the inner wall of the autogenous grinding mill cylinder 1 through fixing holes 6 and fixing bolts. Then, one end of the fixing rod 9 is snapped into the top rod groove. Next, multiple liner plates 8 are fitted onto the fixing rod 9 through sleeve holes, and are engaged with the locking groove 10 at the bottom of the connecting base plate 11 and the locking strip 3, further enhancing the stability of the liner plates 8 on the inner wall of the autogenous grinding mill cylinder 1. At this time, the wear-resistant layer 12 and the sound insulation layer 7 are firmly installed in the grooves 5 on both sides. The installation of multiple liner plates 8 forms multiple sets of liner plates 13. Finally, multiple fixing blocks 2 at the other end are snapped into the fixing rod 9 at the other end, and then fixed to the inner wall of the autogenous grinding mill cylinder 1 through fixing holes 6 and fixing bolts.

[0037] When the wear-resistant layer 12 needs to be replaced, there is no need to remove the entire liner 8. The wear-resistant layer 12 and the sound insulation layer 7 can be taken out directly through the groove 5 and replaced with new wear-resistant layer 12 and sound insulation layer 7.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
