Description

Technical Field

[0001] The utility model belongs to the technical field of gold refining, and in particular relates to a pulverizing device for gold refining. Background Art

[0002] Gold refining is a field with a long history and constantly advancing technology. Traditionally, gold refining mainly comes from gold ore, but with the development of technology, electronic waste has also become an important source of gold recycling. The main purpose of gold refining is to remove impurities and increase the purity of gold to meet the quality standards of market transactions. Powdering equipment can grind gold raw materials into fine particles or powder, increase the contact area between the raw materials and chemical reagents, thereby increasing the reaction rate and extraction efficiency.

[0003] At present, the existing pulverization equipment for gold refining has significant deficiencies in the material screening process. Since the material cannot be fully crushed and effectively screened, the pulverization efficiency is low, which becomes a bottleneck restricting the efficiency of the entire refining process. This inefficient screening not only prolongs the refining cycle, but also makes the material particle size distribution uneven, thereby affecting the pulverization quality of gold. The uneven distribution of particles not only increases the difficulty of subsequent processing, but also directly affects the recovery rate and purity of gold, thereby reducing the quality and market competitiveness of the final product. Utility Model Content

[0034] Furthermore, the workbench 1 bears and fixes other components to ensure the stable operation of the device. The crushing barrel 2 is used to load the gold raw materials to be pulverized. The screening mechanism 3, i.e., the vibrating screen 304, realizes the screening of materials, screens the preliminarily crushed materials. The vibrating motor 306 drives the screen 304 to vibrate. By using the aperture size of the screen 304, the crushed particles are screened. The springs 303 and the limiting rods 302 provide buffering and limiting to ensure the stability of the screening process, so as to quickly and effectively screen the crushed particles and separate the fine particles that meet the requirements. The lifting mechanism 4 is used to control the lifting of the bucket cover 403 and the primary crushing mechanism 5, open or close the crushing barrel 2 from the front. The atomization chamber 6 is used to further refine the screened materials to form finer gold powder. The high-pressure water and gas crushing mechanism 8 generates a high-pressure water and gas mixture through the high-pressure air pump 805 and the high-pressure water pump 806 to realize the rapid and effective refinement of the materials.

[0035] Specifically, the lifting mechanism 4 includes an electric push rod 401 fixedly installed on the top of the workbench 1. The top of the electric push rod 401 is fixedly installed with a mounting plate 402. The bottom of one end of the mounting plate 402 is fixedly installed with a bucket cover 403.

[0037] Specifically, the primary crushing mechanism 5 includes a drive motor 501 fixedly installed on the top of one end of the mounting plate 402. The output shaft of the drive motor 501 penetrates the mounting plate 402, and the end is fixedly connected with a stirring shaft 502. The outer part of the bottom of the stirring shaft 502 is fixedly installed with crushing blades 503.

[0038] Furthermore, the drive motor 501 drives the stirring shaft 502 to rotate, and the stirring shaft 502 drives the crushing blades 503 to preliminarily crush the raw materials, efficiently preliminarily crushing the raw materials to prepare for subsequent screening and atomization.

[0039] Specifically, a discharge port 9 is provided at the bottom of the crushing barrel 2. A hopper 10 is fixedly installed at the bottom of the discharge port 9. The bottom end of the hopper 10 is connected to the through hole 301.

[0041] Specifically, a discharge pipe 11 is fixedly installed at the bottom of the atomization chamber 6. A discharge valve 12 is provided at the end of the discharge pipe 11.

[0042] Furthermore, the atomization chamber 6 provides a closed environment to ensure the normal operation of the high-pressure water and gas crushing mechanism 8. The discharge pipe 11 and the discharge valve 12 are used to control the discharge of the refined powder in the atomization chamber 6.

[0043] Specifically, the high-pressure water and gas crushing mechanism 8 includes a connecting ring 801 fixedly installed at the inner top of the atomization chamber 6. A number of nozzles 802 are equidistantly distributed at the bottom of the connecting ring 801. An air pipe 803 and a water pipe 804 are respectively fixedly connected to both sides of the connecting ring 801. The end of the air pipe 803 is fixedly connected to a high-pressure air pump 805, and the end of the water pipe 804 is fixedly connected to a high-pressure water pump 806. One end of the high-pressure water pump 806 is fixedly connected to a water tank 807.

[0044] Furthermore, the high-pressure air pump 805 and the high-pressure water pump 806 respectively generate high-pressure gas and high-pressure water. The gas and water are mixed in the connecting ring 801 and then sprayed out through the nozzles 802. The impact force of the high-pressure water and gas mixture is used to crush the particles, which can efficiently and quickly refine the particles to obtain finer gold powder.

[0045] Working principle:

[0046] During use, first turn on the device power supply to ensure the normal operation of all components. Check the water volume in the water tank 807 to ensure there is enough for atomization and refinement. Drive the mounting plate 402 to rise through the electric push rod 401 to make the bucket lid 403 leave the crushing bucket 2. Add the gold raw material to be pulverized into the crushing bucket 2. Drive the lifting mechanism 4 to lower, so that the bucket lid 403 closes the crushing bucket 2. Start the transmission motor 501 to drive the stirring shaft 502 to rotate, and then drive the crushing blades 503 to initially crush the raw material. Start the vibration motor 306 to drive the screen 304 to vibrate and screen. The crushed material enters the screening mechanism 3 through the discharge port 9 and the hopper 10. The fine particles that meet the requirements are screened out, and the particles that do not meet the requirements are bounced up and enter the primary crushing mechanism 5 again for re-crushing. Start the high-pressure air pump 805 and the high-pressure water pump 806 to generate high-pressure gas and high-pressure water. After the gas and water are mixed in the connecting ring 801, they are sprayed out through the nozzles 802 to atomize and refine the screened material. The refined gold powder is collected in the atomization chamber 6. Open the discharge valve 12 and discharge the refined gold powder through the discharge pipe 11.

[0047] In summary, through the setting of the screening mechanism 3, fine particles that meet the requirements can be separated. By driving the vibrating screen mesh 304 to vibrate through the vibrating motor 306, the preliminarily crushed materials can be efficiently screened. At the same time, the particles that do not meet the requirements are bounced up and enter the primary crushing mechanism 5 again for re-crushing, thereby improving the overall pulverization efficiency. Through the primary crushing mechanism 5, the raw materials can be preliminarily and rapidly crushed under the action of the driving motor 501 and the crushing blades 503, reducing the subsequent processing time for screening and atomization refinement. Through the high-pressure water-gas mixture generated by the high-pressure air pump 805 and the high-pressure water pump 806, the screened materials are atomized and refined, which can further refine the particles into finer gold powder, improving the pulverization quality.
