[0002] In the gold smelting process, in order to ensure that the gold in the gold concentrate can be fully extracted, the gold concentrate needs to be crushed and processed in advance during the gold smelting process.

[0003] Currently, jaw crushers are the main pretreatment devices used for crushing gold smelting concentrates. When crushing gold concentrate, the crushing is mainly achieved by the collision between the gold concentrate and the impact plates inside the jaw crusher. Although jaw crushers can crush gold concentrates, this method is prone to inaccurate control of the impact particle size between the gold concentrate and the impact plates, resulting in inconsistent particle size and poor crushing quality after crushing. It is also easy to over-crush, which is not conducive to efficient gold smelting in subsequent processes. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3As shown, this embodiment of a concentrate pretreatment device for gold smelting includes a crushing box 3. A primary crushing mechanism 1 is installed in the upper part of the crushing box 3. The primary crushing mechanism 1 includes a motor 102 installed on the upper part of one side wall of the outer side of the crushing box 3. The power output end of the motor 102 is connected to a crushing roller 101. A vibrating screening mechanism 7 is installed in the middle of the crushing box 3. The vibrating screening mechanism 7 includes a vibrating motor 701, a spring 702, a telescopic rod 703, a support plate 704, and a screening screen 705. The support plate 704 is welded to the middle of the crushing box 3. The telescopic rod 703 is symmetrically installed on both sides of the top plate of the support plate 704. The top of the telescopic rod 703 is connected to the screening screen 705. A spring 702 is installed at the bottom of the screening screen 705 outside the telescopic rod 703. A vibrating motor 701 is also installed in the middle of the bottom of the screening screen 705. Two discharge ends of the screening screen 705 are respectively installed in the crushing box 3. A collection frame 8 is provided, and a secondary crushing mechanism 2 is installed inside the collection frame 8. The secondary crushing mechanism 2 includes a crushing roller 201 installed inside the collection frame 8. A motor 202 is installed on the side of the crushing box 3, directly opposite the core shaft of the crushing roller 201. When gold concentrate is fed into the crushing box 3, the crushing roller 101 is rotated by the motor 102, which performs initial crushing on the gold concentrate. The crushed gold concentrate falls onto the upper side of the screening screen 705. As the screening screen 705 vibrates up and down at high frequency under the action of the vibrating motor 701, spring 702, and telescopic rod 703, qualified gold concentrate will directly pass through the screening screen 705 and fall into the bottom of the crushing box 3, while unqualified gold concentrate will fall into the collection frame 8. While the crushing roller 201 is rotated by the motor 202, the gold concentrate will undergo secondary crushing. The processed gold concentrate will fall into the bottom of the crushing box 3.

[0018] like Figures 1-3 As shown, in this embodiment, a support leg 5 is welded to each of the four corners of the bottom of the crushing box 3. A discharge pipe 6 is also installed in the middle of the bottom of the crushing box 3. The support leg 5 is mainly used to stabilize the crushing box 3, and the discharge pipe 6 is mainly used to discharge the crushed gold concentrate. An operation panel 4 is installed on one side wall of the crushing box 3 above the second motor 202. The operation panel 4 integrates a control module, which is mainly used to realize the on-demand operation of the first motor 102, the second motor 202 and the vibration motor 701.

[0019] like Figures 1-3As shown, in this embodiment, motor 102 is bolted to crushing box 3, and motor 102 is connected to crushing roller 101 via coupling. Motor 102 mainly provides power for the rotation of crushing roller 101. The middle part of support plate 704 is a horizontal structure, and the two sides of support plate 704 are downward inclined structures. Support plate 704 mainly provides an installation base for screening screen plate 705, spring 702, and telescopic rod 703. At the same time, designing the two sides of support plate 704 as a downward inclined structure can reduce the risk of gold concentrate accumulating on support plate 704 when falling from and from screening screen plate 705, and facilitate the falling of gold concentrate. Vibration motor 701 is bolted to screening screen plate 705. The top center of the screen plate 705 has an arc-shaped structure. The two sides of the screen plate 705 have downward-sloping mesh structures. The telescopic part of the telescopic rod 703 is bolted to the screen plate 705, and the fixed part of the telescopic rod 703 is bolted to the support plate 704. The arc-shaped structure at the top of the screen plate 705 allows the gold concentrate after primary crushing to flow down in a diverted manner, so that the gold concentrate can be evenly distributed on the mesh surface of the screen plate 705. The telescopic rod 703 passes through the spring 702. The top of the spring 702 is welded to the screen plate 705, and the bottom of the spring 702 is welded to the support plate 704. The telescopic rod 703 is mainly used to guide the extension and retraction of the spring 702, reducing the risk of the spring 702 tilting and being damaged.

[0020] like Figures 1-3 As shown, in this embodiment, the collection frame 8 is a square frame, and the collection frame 8 is bolted to the crushing box 3. The crushing roller 201 is rotatably connected to both the crushing box 3 and the collection frame 8. The motor 202 is connected to the crushing roller 201 by a coupling. The motor 202 is mainly used to provide power for the rotation of the crushing roller 201 so as to perform secondary crushing pretreatment on the gold concentrate.

[0021] The specific implementation process of this embodiment is as follows: When the gold concentrate is fed into the crushing box 3, the gold concentrate is initially crushed while the crushing roller 101 is rotated by the motor 102. The crushed gold concentrate falls onto the upper side of the screening screen plate 705. As the screening screen plate 705 vibrates up and down at high frequency under the action of the vibrating motor 701, spring 702 and telescopic rod 703, qualified gold concentrate will directly pass through the screening screen plate 705 and fall into the bottom of the crushing box 3, while unqualified gold concentrate will fall into the aggregate. In frame 8, while the second motor 202 drives the second crushing roller 201 to rotate, it will perform secondary crushing treatment on the gold concentrate. The processed gold concentrate will fall into the bottom of the crushing box 3 and finally be discharged through the discharge pipe 6. Because the gold concentrate is crushed by two roller crushing and grinding methods under the action of this crushing pretreatment device, the gold concentrate is not only crushed to be more uniform in particle size and better in crushing quality, but also effectively reduces the phenomenon of over-crushing, which facilitates the efficient smelting of gold concentrate in subsequent processing.

[0022] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
