Description

Technical Field

[0001] The utility model relates to the technical field of mills, in particular to an integrated composite arc-shaped grating plate. Background Art

[0002] The mill is one of the commonly used equipment for crushing and grinding ore materials in the ore dressing process. In recent years, with the development of mill design and manufacturing technology, the size of mills has gradually become larger, and various types of autogenous mills and semi-autogenous mills have also been gradually promoted and applied.

[0003] In various large-scale autogenous mills and large-scale semi-autogenous mills, the grate plate plays a decisive role in the quality of mineral processing (such as the processing volume of ore, the particle size of the processed pulp and other quality characteristics). However, in the actual mineral processing process, the technicians found that the grate plates of the current large-scale semi-autogenous mills and large autogenous mills also have the following defects: During the installation process, lifting bars are provided on both sides of each grate plate, and the side extension of the grate plate is pressed by the lifting bars to fix the grate plate. At this time, since the two are separated from each other, it takes time to ensure the accuracy of their alignment during installation. At the same time, the existing grate plates are all processed by metal casting technology, which leads to a large weight of the grate plates; especially for large mills. This makes the existing grate plates difficult to install. In the mineral processing process, since the lifting bars are only located on both sides of the grate plate, the residence time of the ore on the grate plate is limited, which also leads to low discharge efficiency. Utility Model Content

[0004] The utility model aims to provide an integrated composite arc-shaped grating plate to solve the technical problems that the grating plates in the existing mills are difficult to install during the installation process and have poor ore discharge effect in actual application.

[0005] In order to achieve the above purpose, the utility model proposes the following technical solutions:

[0006] In the first aspect, the technical solution provides an integrated composite curved grating plate. The grating plate comprises: a frame, a plurality of curved lifting strips, a plurality of grating bottom plates, adhesives and coverings; wherein the frame, any of the curved lifting strips and any of the grating bottom plates are made of metal, and the adhesives and coverings are made of cured adhesive materials;

[0007] The arc-shaped lifting strips and the lattice bottom plate are both arranged above the frame at intervals; wherein the arc-shaped lifting strips are arranged at intervals along the radial direction of the frame; the lattice bottom plate is laid in other areas where the arc-shaped lifting strips are not arranged, and the lattice bottom plate between any two arc-shaped lifting strips is a splicing structure;

[0008] The adhesive is filled in any gap between any of the arc-shaped lifting strips, any of the lattice bottom plates and the frame, so as to form an integrated structure of each of the arc-shaped lifting strips, each of the lattice bottom plates and the frame; wherein the thickness of the adhesive between any of the arc-shaped lifting strips and the frame is greater than the thickness of the adhesive between any of the lattice bottom plates and the frame;

[0009] The covering member covers the outer surface of any one of the arc-shaped lifting strips, any one of the lattice bottom plates and the frame.

[0010] Furthermore, any of the arc-shaped lifting bars is a circular arc-shaped lifting bar; the radius of the circular arc-shaped lifting bar ranges from 1.5m to 5m.

[0011] Furthermore, the thickness of the region corresponding to the frame and the arc-shaped lifting strip is smaller than the thickness of the remaining region.

[0012] Further, comprising a first through hole and a second through hole;

[0013] Each of the arc-shaped lifting strips is provided with a protrusion, and the first through hole is opened in the protrusion; the second through hole is opened on the frame; wherein the first through hole and the second through hole have the same size and correspond one to one in position.

[0014] Furthermore, the longitudinal section of the arc-shaped lifting strip is trapezoidal in shape.

[0015] Furthermore, a boss structure is provided on the bottom surface of any of the arc-shaped lifting strips.

[0016] Furthermore, the thickness of the adhesive between any of the lattice bottom plates and the frame is not less than 10 mm.

[0017] Furthermore, the adhesive component and the covering component are both made of rubber.

[0018] Furthermore, any of the lattice bottom plates is provided with a plurality of waist-shaped lattice holes; and the shape of the longitudinal section of any of the waist-shaped lattice holes is a trapezoid.

[0019] In a second aspect, the technical solution provides a grinding mill, wherein the grinding mill comprises the integrated composite arc-shaped grating plate.

[0020] Beneficial effects:

[0021] The technical solution improves the existing grating plate and designs an integrated composite arc grating plate to simultaneously improve the technical defects of the current grating plate, namely, the difficulty in installation and the low ore discharge efficiency.

[0022] The lattice plate is composed of a frame, a plurality of arc-shaped lifting bars, a plurality of lattice bottom plates, adhesives and coverings. In terms of specific structure, the arc-shaped lifting bars and the lattice bottom plates are both spaced apart above the frame; wherein each of the arc-shaped lifting bars is spaced apart along the radial direction of the frame; the lattice bottom plates are laid in other areas where the arc-shaped lifting bars are not set, and the lattice bottom plates between any two of the arc-shaped lifting bars are spliced ​​structures. The adhesive is filled in any gap between any of the arc-shaped lifting bars, any of the lattice bottom plates and the frame, so as to form an integrated structure between each of the arc-shaped lifting bars, each of the lattice bottom plates and the frame; wherein the thickness of the adhesive between any of the arc-shaped lifting bars and the frame is greater than the thickness of the adhesive between any of the lattice bottom plates and the frame. The covering covers the outer surface of any of the arc-shaped lifting bars, any of the lattice bottom plates and the frame.

[0023] At this time, under the action of the adhesive and the covering parts, the frame, the grating bottom plate and the arc-shaped lifting strips form an integral structure. During the installation process, there is no need to install and position the lifting strips and the grating plate separately, thereby reducing the difficulty of installation. At the same time, since the adhesive and the covering parts are made of cured adhesive, the weight of the entire grating plate is effectively reduced compared to the grating plate processed only by metal casting, which is also conducive to reducing the difficulty of installation. In the mineral processing process, since the lifting strips are designed as arc structures, and the arc-shaped lifting strips and the grating bottom plate are staggered along the radial direction of the frame, the residence time of the ore on the grating plate is increased, and the discharge efficiency is improved. At the same time, the grating bottom plate between the two arc-shaped lifting bars is arranged as a splicing structure to improve the bonding effect of the adhesive thereto so as to avoid the large-sized grating bottom plate from being worn and falling off. The thickness of the adhesive between any of the arc-shaped lifting bars and the frame is arranged to be greater than the thickness of the adhesive between any of the grating bottom plates and the frame so as to improve the structural strength of the arc-shaped lifting bars in the integrated grating plate when facing the impact of mineral materials. This further improves the practical life of this type of integrated grating plate, avoids frequent replacement of spare parts, and also improves the ore discharge efficiency from the perspective of increasing the continuous working time of the mill.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with general skills in the field to which the utility model belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] The grating plate plays a decisive role in the ore dressing process in large semi-autogenous mills and large autogenous mills. Factors such as ore processing capacity and pulp particle size are all determined by the structure of the grating plate. However, technicians have found that the grating plate with traditional structure in the current mill has the defects of heavy weight, cumbersome alignment, and troublesome installation and disassembly during installation, and low ore discharge efficiency during use. Therefore, this embodiment aims to provide an integrated composite arc grating plate to improve the above technical defects at the same time.

[0034] The integrated composite curved grating plate disclosed in the present utility model is further specifically introduced below in conjunction with the embodiments shown in the accompanying drawings.

[0035] like Figure 1-3 As shown, the lattice plate includes a frame 1, a plurality of arc-shaped lifting strips 2, a plurality of lattice bottom plates 3, an adhesive 4 and a covering 5. The frame 1, any of the arc-shaped lifting strips 2 and any of the lattice bottom plates 3 are made of metal; in this embodiment, the metal is specifically a wear-resistant metal alloy. The adhesive 4 and the covering 5 are made of cured adhesive material; in this embodiment, the cured adhesive material is specifically rubber.

[0036] In terms of specific structural settings, the corresponding positions of the skeleton 1 and the grating bottom plate 3 are hollow structures for providing the grating holes 31 on the grating bottom plate 3. In the present embodiment, the grating holes 31 are specifically waist-shaped grating holes. The shape of the longitudinal section of any waist-shaped grating hole is set to be trapezoidal. (In the present embodiment, the longitudinal section is defined as a section extending from the working surface of the grating plate to the non-working surface opposite thereto.) At this time, when mineral processing is being carried out, the waist-shaped grating holes with a trapezoidal longitudinal section can effectively avoid being blocked by the steel balls and ore materials in the mill cylinder, thereby ensuring the smooth progress of mineral processing.

[0037] The arc-shaped lifting bars 2 and the lattice bottom plate 3 are both arranged above the frame 1 at intervals. The arc-shaped lifting bars 2 are arranged at intervals along the radial direction of the frame 1; the lattice bottom plate 3 is laid in other areas where the arc-shaped lifting bars 2 are not arranged, and the lattice bottom plate 3 between any two arc-shaped lifting bars 2 is a splicing structure.

[0038] The adhesive 4 is filled in any gap between any of the arc-shaped lifting strips 2, any of the lattice bottom plates 3 and the frame 1, so as to form an integrated structure of each of the arc-shaped lifting strips 2, each of the lattice bottom plates 3 and the frame 1. The thickness of the adhesive 4 between any of the arc-shaped lifting strips 2 and the frame 1 is greater than the thickness of the adhesive 4 between any of the lattice bottom plates 3 and the frame 1. In a specific implementation, the thickness of the adhesive 4 between any of the lattice bottom plates 3 and the frame 1 is not less than 10 mm.

[0039] The covering member 5 covers the outer surface of any of the arc-shaped lifting strips 2 , any of the lattice bottom plates 3 and the frame 1 .

[0040] During specific processing, the lattice plate is integrally connected and formed by a vulcanization process. In order to facilitate demoulding after forming, the shape of the longitudinal section of the arc-shaped lifting strip 2 is set to be a trapezoid.

[0041] For the vulcanized lattice plate, during its installation, due to the action of the adhesive 4 and the covering 5, the frame 1, any of the lattice bottom plates 3 and any of the arc-shaped lifting strips 2 form an integral structure, so it is no longer necessary to install the lifting strips and the lattice plate separately, and no positioning operation is involved, thereby reducing the difficulty of installation. At the same time, since the adhesive 4 and the covering 5 are made of cured adhesive, compared with the lattice plate processed only by metal casting, the weight of the entire lattice plate is effectively reduced, which is also conducive to reducing the difficulty of installation.

[0042] When the grating plate formed by vulcanization connection is used for mineral processing, on the one hand, the lifting bar is designed as an arc structure, and the arc lifting bar 2 and the grating bottom plate 3 are staggered along the radial direction of the frame 1; thereby, the residence time of the ore on the grating plate is increased, and the ore discharge efficiency is improved. On the other hand, the grating bottom plate 3 between the two arc lifting bars 2 is set as a splicing structure to improve the bonding effect of the adhesive 4 to it to avoid the large-sized grating bottom plate from being worn and falling due to loose bonding. At the same time, the thickness of the adhesive 4 between any of the arc lifting bars 2 and the frame 1 is set to be greater than the thickness of the adhesive 4 between any of the grating bottom plates 3 and the frame 1 to improve the structural strength of the arc lifting bar 2 in the integrated grating plate when facing the impact of the ore. The practical life of this type of integrated grating plate is further improved, avoiding frequent replacement of spare parts, and also improving the ore discharge efficiency from the perspective of increasing the continuous working time of the mill.

[0043] In this embodiment, any of the arc-shaped lifting bars 2 is a circular arc-shaped lifting bar. During the specific implementation, the technicians found that when the number of the circular arc-shaped lifting bars is three, the radius of any of the circular arc-shaped lifting bars is in the range of 1.5m to 5m; it has the best discharge effect without affecting other structural settings of the mill.

[0044] As an optional implementation, in order to improve the structural strength of the arc-shaped lifting strip 2 when facing the impact of mineral materials, the thickness of the corresponding area of ​​the frame 1 and the arc-shaped lifting strip 2 can be set to be smaller than the thickness of the remaining area. In this case, the thickness of the adhesive 4 between the arc-shaped lifting strip 2 and the frame 1 can be further increased compared to the thickness of the adhesive 4 between the lattice bottom plate 3 and the frame 1.

[0045] At the same time, a boss 23 is also provided on the bottom surface of any of the arc-shaped lifting strips 2. At this time, the structural strength can be improved by increasing the contact area between the arc-shaped lifting strip 2 and the adhesive member 4.

[0046] As a specific implementation, in order to realize the installation of the grating plate, the grating plate is provided with a first through hole 22 and a second through hole 11. Specifically, each of the arc-shaped lifting bars 2 is provided with a protrusion 21, and the first through hole 22 is opened on the protrusion 21; the second through hole 11 is opened on the frame 1. The first through hole 22 and the second through hole 11 have the same size and correspond to each other in position. At this time, the correspondingly arranged first through hole 22 and the second through hole 11 will form a mounting hole to realize the installation of the grating plate at the discharge end of the mill.

[0047] This embodiment also provides a mill. The mill includes the integrated composite arc-shaped grating plate. In this case, the mill has the technical advantages of more convenient overall installation, longer continuous ore dressing time, and higher ore discharge efficiency when used.

[0048] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
