Description

[0002] In the development and utilization of domestic mineral resources, the traditional mineral processing process follows the steps of "crushing-grinding-ore dressing", and this process relies on mechanical equipment to complete the crushing and grinding operations. However, this method causes the fine crushing chamber of the mechanical equipment to be easily blocked, and the entire crushing and grinding process faces the problems of high energy consumption, serious over-crushing, and large subsequent resource losses. In response to these problems, the invention patent entitled "A device and method for controllable shock wave crushing of ore" (publication number: CN114433330A) proposes a shock wave ore crushing technology, which aims to improve the deficiencies in traditional processes and optimize the crushing process. However, the shock wave ore crushing technology requires the ore to be placed in a water environment for operation. This requirement increases the complexity of the crushing and separation process, and also makes the overall structural design of the crushing equipment more cumbersome, which in turn has a certain negative impact on the ore crushing efficiency.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0027] like Figures 1 to 4 As shown, the dry ore crushing device provided by the embodiment of the utility model includes a crushing tube 1, a mounting plate 4, a bag 6, a moving plate 7, a shock wave generating assembly and a lifting device 9.

[0028] A discharge plate 2 is movably installed in the middle of the crushing cylinder 1, a feed port is arranged at the upper part of the side wall of the crushing cylinder 1, and a discharge port 3 is arranged at the lower part of the side wall of the crushing cylinder 1.

[0029] A mounting plate 4 is arranged at the upper part of the crushing cylinder 1, and a plurality of mounting holes 5 are evenly distributed on the mounting plate 4. A bag 6 is arranged in each mounting hole 5, and the upper end of the bag 6 is open.

[0030] The movable plate 7 is disposed on the mounting plate 4 , and the upper edge of the bag 6 is clamped between the movable plate 7 and the mounting plate 4 .

[0031] The movable plate 7 is provided with a plurality of shock wave generating assemblies, which correspond one to one with the plurality of mounting holes 5 . The metal wires 8 of the shock wave generating assemblies extend into the bladder bags 6 . The movable plate 7 is provided with water injection holes above each bladder bag 6 .

[0032] The lifting device 9 is disposed above the moving plate 7 , and a lifting end of the lifting device 9 is connected to an upper end of the moving plate 7 .

[0033] It should be noted that the feed port and the discharge port 3 are respectively located at the upper and lower parts of the discharge plate 2, and the mounting plate 4 is used to install the bladder bag 6. Each bladder bag 6 can be an independent structure or an integrated structure. When it is an integrated structure, a plurality of bladder bags 6 are arranged on the rubber plate. The thickness of the bladder bag 6 is 5 mm, and the material of the bladder bag 6 is flexible and highly tear-resistant silicone rubber. The upper edge of the bladder bag 6 is clamped between the movable plate 7 and the mounting plate 4, which can play a sealing effect, so that a sealed cavity is formed inside the bladder bag 6, and water can be stored to prevent water from seeping out. The movable plate 7 can also be provided with a drainage hole above each bladder bag 6 to discharge the water in the bladder bag 6, which is convenient for replacing the metal wire 8 and the next shock wave operation. The drainage hole can be connected to a pumping device.

[0034] When the device is used, the ore is placed on the discharge plate 2 through the feed port, and the movable plate 7 and the mounting plate 4 are moved down as a whole and close to the ore through the lifting device 9. Water is injected into multiple bags 6 through the water injection hole, and the water can open the bags 6 until the lower end of the bags 6 abuts against the top surface of the ore. Multiple bags 6 abut at different positions on the top surface of the ore, and the flexible bags 6 can adapt to the structure of the top surface of the ore, thereby improving the operation effect. Then, the metal wire 8 is energized, and the metal wire 8 explodes to generate shock waves. The shock waves are transmitted through the bags 6 under the transmission of the water medium and directly act on the ore, thereby causing cracks in the ore. The state of the bags 6 will not change during the shock wave operation, so the bags 6 can be reused. After the shock wave operation is completed, the water in the bags 6 is discharged, and then the movable plate 7 and the mounting plate 4 are separated. After the metal wire 8 is replaced, the movable plate 7 and the mounting plate 4 are reset, so that the next shock wave operation can be carried out. After multiple operations, the ore is crushed, and then the discharge plate 2 is adjusted to discharge the crushed ore from the discharge port 3. The device uses a bag 6 to perform shock wave operation on the ore, thereby avoiding the problem of the prior art that the ore needs to be placed in a water environment before the shock wave operation can be performed, thereby facilitating the removal of the crushed ore and subsequent operations. After some of the bags 6 in the multiple bags 6 are broken, the amount of water leaked is small, avoiding the problem of large water leakage after the rupture of a water bag, and also facilitating the local implementation of shock wave operation on the ore. The device improves the efficiency of shock wave crushing, and the device has a simple structure and strong practicality.

[0035] In this embodiment, one end of the discharge plate 2 is hinged to the inner wall of the crushing cylinder 1, and the other end of the discharge plate 2 is arranged close to the feed port.

[0036] The fixed end of the telescopic device 10 is hinged to the lower part of the inner wall of the crushing cylinder 1 , and the telescopic end of the telescopic device 10 is hinged to the bottom center of the discharge plate 2 .

[0037] It should be noted that when the telescopic device 10 is telescoped, it can drive the stripper plate 2 to rotate around its hinge axis, thereby switching the stripper plate 2 between a horizontal state and an inclined state, wherein the inclined state is a state where the stripper plate 2 is at the maximum inclination angle.

[0038] In this embodiment, the shock wave generating assembly includes two electrode holders 11 and a metal wire 8. The two electrode holders 11 are installed on the movable plate 7. The two ends of the metal wire 8 are respectively connected to the two electrode holders 11. The two electrode holders 11 are respectively connected to the two output ends of the pulse power driving source.

[0039] It should be noted that a plurality of shock wave generating components are arranged in parallel, and a pulse power driving source supplies high voltage direct current to the metal wire 8 through two electrode holders 11. After the high voltage direct current is loaded to the metal wire 8, the metal wire 8 is electrically exploded to generate shock waves.

[0040] In this embodiment, the water injection hole is connected to an output port of the water distribution pipe 13 through the water supply branch 12, and the water inlet of the water distribution pipe 13 is connected to the water outlet of the water tank through the water supply main pipe 14. A booster pump is provided on the water tank, and a valve and a pressure gauge are provided on the water supply main pipe 14.

[0041] It should be noted that, when the valve of the water tank is opened, water is output through the water delivery main pipe 14 under the action of the booster pump. The water distribution pipe 13 plays a diversion role, and the water distribution pipe 13 is provided with multiple output ports, and the multiple output ports inject water into multiple bags 6 through the water distribution pipe 13. During water delivery, when the pressure gauge detects that the pressure value reaches the set reading, for example, when the pressure gauge reading is 0.5-1.5MPa, the lower end of the bag 6 abuts against the top surface of the ore, and then the valve is closed, thereby completing the water injection process.

[0042] In this embodiment, the side wall of the crushing tube 1 is provided with an observation window.

[0043] It should be noted that tempered glass can be installed at the observation window so that the staff can understand the ore crushing situation in time.

[0044] In this embodiment, a plurality of limiting holes 15 are provided on the upper side wall of the crushing cylinder 1 , and sliding pins 16 are provided in the limiting holes 15 . The ends of the sliding pins 16 are used to support the bottom surface of the mounting plate 4 .

[0045] It should be noted that when the mounting plate 4 and the movable plate 7 move up and down, the sliding pin 16 is disassembled or its end is moved out of the crushing cylinder 1. When the movable plate 7 and the mounting plate 4 are separated, the mounting plate 4 is moved above the limiting hole 15, and then the sliding pin 16 is moved so that the mounting plate 4 is supported by the end of the sliding pin 16, thereby temporarily fixing the mounting plate 4.

[0046] In this embodiment, a side baffle 17 is provided in the circumference of the mounting plate 4 , and a clamping plate 18 is detachably mounted on the top of the side baffle 17 .

[0047] A top plate 19 is provided on the movable plate 7, and the top plate 19 is fixed by a plurality of columns 20 and the movable plate 7. The plurality of columns 20 are arranged in the circumference of the movable plate 7. The top plate 19 and the movable plate 7 are both located in a groove body surrounded by the side baffle plates 17, and the top surface of the top plate 19 abuts against the lower surface of the clamping plate 18.

[0048] It should be noted that, by providing the top plate 19 and a plurality of columns 20 , an equipment space can be formed between the top plate 19 and the movable plate 7 , and this equipment space can accommodate the electrode holder 11 , electrical cables, water pipelines, and the like.

[0049] After the top plate 19 and the movable plate 7 are placed in the groove body surrounded by the side baffles 17 and the clamping plate 18 is installed, the installation plate 4, the top plate 19 and the movable plate 7 can be fixed as a whole.

[0050] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
