Description

Technical Field

[0001] This utility model relates to the field of gold extraction agent technology, and more specifically, it relates to a gold extraction agent grinding and screening device. Background Technology

[0002] In mineral extraction and metal beneficiation processes, the grinding and screening of gold extraction agents requires the use of screening equipment of different specifications according to different particle requirements and throughput. In particular, in multi-stage screening and fine classification processes, it is often necessary to replace screening components with different apertures and materials to adapt to the screening needs of different process stages.

[0003] In existing technologies, the fixing methods for screening components typically employ traditional bolt fastening or clip-on clamping structures. When replacing screening components, operators need to stop the machine and disassemble multiple fasteners. The entire replacement process requires not only the use of specialized tools for individual disassembly and assembly but also the readjustment and calibration of the screening gap. The operation steps are cumbersome and time-consuming, which seriously affects production continuity and equipment utilization. Furthermore, frequent disassembly and assembly operations may lead to wear or deformation of the screening components, making it difficult to meet the urgent needs of modern mineral processing technology for efficient screen replacement and continuous operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a gold extraction agent grinding and screening device, which has the following beneficial effects:

[0017] 1. This device achieves rapid installation and disassembly of different types of screen plates through multiple sets of fixing mechanisms set on the screen plate. The fixing mechanism adopts an insertion structure of plug rod and fixing sleeve. The operator only needs to insert the screen plate into the plug rod through the plug hole and then insert the fixing sleeve into the plug rod to complete the automatic locking of the screen plate. When replacement is required, the rotating sleeve is rotated to move the relief groove to the position of the limiting plate, and the locking block automatically disengages from the slot. The entire installation and disassembly process does not require the use of any special tools or the removal of multiple fixing parts, which greatly shortens the screen plate replacement time and improves the convenience of operation. It effectively reduces equipment downtime and production interruption. At the same time, the reliable locking of the locking block and the slot and the limiting effect of the locking sleeve on the locking block ensure the stability of the screen plate during high-frequency vibration, avoiding loosening or damage caused by improper installation or uneven fixing force, and significantly improving the screening effect and product quality.

[0018] 2. The limiting mechanism in this device achieves precise control and rapid unlocking of the sliding sleeve position through the structure of the rotating sleeve, the limiting plate, and the clearance groove. After the screen plate is installed, the limiting plate is located on both sides of the limiting sleeve to form a reliable position restriction. By rotating the rotating sleeve, the clearance groove can be precisely aligned with the limiting plate to achieve rapid unlocking. This avoids the tedious operation of disassembling and assembling fixed parts one by one in traditional equipment, effectively reducing the special tools and fixed parts required for screen plate replacement, lowering equipment investment costs and spare parts management difficulty. At the same time, the cooperation between the positioning block and the positioning groove ensures the accurate positioning of the rotating sleeve, guaranteeing the reliability and repeatability of the limiting mechanism.

[0019] 3. The screening box in this device, in conjunction with the vibration transmission mechanism of pulleys and sliding grooves, achieves efficient and stable screening operations. The motor drives the screening box to move repeatedly along the arc-shaped sliding groove through the eccentric wheel and connecting rod. This structure can provide uniform and stable vibration force to the screen plate and ensure the continuity of the screening process, avoiding the impact of long-term downtime for replacement on production continuity. It effectively improves equipment utilization and processing efficiency, while reducing the increase in energy consumption caused by production interruption. It meets the strict requirements of modern mineral processing for high efficiency and low cost, and ensures that different batches of raw materials can be quickly switched and maintain stable screening accuracy.

[0031] The top of the support frame 1 is provided with a sliding groove 19. There are multiple sets of sliding grooves 19, all of which are arc-shaped. Multiple sets of pulleys 4 slide in the multiple sets of sliding grooves 19 respectively.

[0032] The sieve plate 3 has multiple sets of insertion holes 20, which are respectively connected to multiple sets of insertion rods 6.

[0033] Each set of locking blocks 9 has a locking groove 21 on its bottom surface, and the top surface of the locking sleeve 15 abuts against the locking groove 21.

[0034] A limiting mechanism is provided on the outer side of the sliding sleeve 14. The limiting mechanism includes a rotating sleeve 22 and a limiting plate 23. The rotating sleeve 22 rotates on the outer wall of the fixed sleeve 7. A support plate 24 is fixedly provided on the outer side of the sliding sleeve 14.

[0035] The outer side of the insertion rod 6 is provided with a strip groove 27, and the inner side of the fixing sleeve 7 is fixed with a positioning strip 28. Multiple sets of both the strip groove 27 and the positioning strip 28 are provided.

[0036] Each of the multiple sliding rods 10 has a top block 29 fixedly installed at its top. A positioning block 30 is slidably installed on the inner side of the rotating sleeve 22. There are multiple sets of positioning blocks 30, and each of them is connected to a return spring 31 between its top and the rotating sleeve 22. The outer wall of the fixed sleeve 7 has a positioning groove 32, which is provided in multiple sets and abuts against the bottom of the multiple sets of positioning blocks 30 respectively.

[0037] In this embodiment, during use, a suitable screen plate 3 is first installed. The screen plate 3 is then inserted into multiple sets of insertion holes 20 and multiple sets of insertion rods 6. Next, the fixing sleeve 7 is inserted into the insertion rods 6. Multiple sets of top blocks 29 are pushed to push the locking blocks 9 into the slots 12 via the sliding rods 10, thus stretching the tension springs 11. The sliding sleeve 14 is pulled to drive the locking sleeve 15 to abut against the multiple sets of locking grooves 21, thus limiting the multiple sets of locking blocks 9. At this time, multiple sets of limiting plates 23 are located on both sides of the limiting sleeve 25. Rotating the rotating sleeve 22 causes the limiting sleeve 25 to abut against the multiple sets of limiting plates 23. Simultaneously, multiple sets of positioning blocks 30 are pushed out of the positioning grooves 32 via the multiple sets of positioning grooves 32 and reset. When the spring 31 is stretched, the rotating sleeve 22 rotates while multiple sets of positioning blocks 30 move along multiple sets of positioning grooves 32. After the rotating sleeve 22 stops rotating, multiple sets of reset springs 31 push the positioning blocks 30 to abut in the positioning grooves 32 to position the rotating sleeve 22. By operating multiple sets of fixing mechanisms in sequence, the installation of the sieve plate 3 can be completed. The raw material is injected into the screening box 2, and the motor 16 is started to drive the eccentric wheel 17 to rotate. The eccentric wheel 17 drives the screening box 2 through the connecting rod 18 to move it repeatedly along the sliding groove 19 through multiple sets of pulleys 4, thereby screening the raw material. Then, the screened raw material is collected by an external collection device.

[0038] More specifically, when the screen plate 3 needs to be replaced, rotating the rotating sleeve 22 causes multiple sets of clearance grooves 26 to move to the inside of the limiting plate 23, releasing the contact between the multiple sets of limiting plates 23 and the limiting sleeve 25. Then, the locking sleeve 15 disengages from the multiple sets of locking grooves 21 to release the restriction on the locking block 9. The locking block 9 is pulled along the movable groove 8 and disengaged from the locking groove 12 by multiple sets of tension springs 11, releasing the engagement with the insertion rod 6. Then, the fixing sleeve 7 is separated from the insertion rod 6, and the screen plate 3 can be disassembled.

[0039] In summary, during the use or operation of the overall equipment: First, install the appropriate model of screen plate 3. Connect the screen plate 3 to the multiple sets of insertion holes 20 and the multiple sets of insertion rods 6. Then, insert the fixing sleeve 7 into the insertion rods 6. Push the multiple sets of top blocks 29 through the slide rod 10 to push the locking blocks 9 into the slots 12, stretching the tension spring 11. Pull the slide sleeve 14 to drive the locking sleeve 15 to abut against the multiple sets of locking grooves 21, limiting the multiple sets of locking blocks 9. At this time, the multiple sets of limiting plates 23 are located on both sides of the limiting sleeve 25. Rotate the rotating sleeve 22 to drive the limiting sleeve 25 to abut against the multiple sets of limiting plates 23. Simultaneously, push the multiple sets of positioning blocks 30 out of the positioning grooves 32 through the multiple sets of positioning grooves 32. The reset spring 31 is stretched, and while the rotating sleeve 22 is rotated, multiple sets of positioning blocks 30 move along multiple sets of positioning grooves 32. After the rotating sleeve 22 stops rotating, the multiple sets of reset springs 31 push the positioning blocks 30 to abut in the positioning grooves 32 to position the rotating sleeve 22. By operating multiple sets of fixing mechanisms in sequence, the installation of the sieve plate 3 can be completed. The raw material is injected into the screening box 2, and the motor 16 is started to drive the eccentric wheel 17 to rotate. The eccentric wheel 17 drives the screening box 2 through the connecting rod 18 to move it repeatedly along the sliding groove 19 through multiple sets of pulleys 4, thereby screening the raw material. Then, the screened raw material is collected by an external collection device.

[0040] When the screen plate 3 needs to be replaced, rotating the rotating sleeve 22 causes multiple sets of clearance grooves 26 to move to the inside of the limiting plate 23, releasing the contact between the multiple sets of limiting plates 23 and the limiting sleeve 25. Then, the locking sleeve 15 disengages from the multiple sets of locking grooves 21 to release the restriction on the locking block 9. The locking block 9 is pulled along the movable groove 8 and disengaged from the locking groove 12 by multiple sets of tension springs 11, releasing the engagement with the insertion rod 6. Then, the fixing sleeve 7 is separated from the insertion rod 6, and the screen plate 3 can be disassembled.
