Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to an integrated device for ore crushing and spraying. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which possesses certain usable properties. Generally, mined ores are in large blocks. To maximize the utilization of the ore or extract effective components, it is often necessary to crush it. Based on the need for ore crushing, ore crushing equipment is one of the essential pieces of equipment in the ore processing process. It is widely used in mining, smelting, and other industries, and its purpose is to break larger ores into smaller, suitable fragments.

[0003] When the crusher is working, the ore is poured into the crushing chamber from the feed inlet. The crushing rollers crush the material. As the ore is poured in, the dust generated during the process is carried by the air and diffuses outward towards the feed inlet or discharge outlet. Inhaling ore dust for a long time can cause very serious harm to the human body. Utility Model Content

[0004] The present invention aims to provide an integrated ore crushing and spraying device to solve the problem that ore dust can easily escape from the inlet or outlet.

[0013] 1. This utility model innovatively extends the feed inlet of the crusher into an inclined feed channel and installs nozzles above the feed channel to initially wet the ore poured into the crusher. Due to the wet ore surface, some dust can be adsorbed during crushing, reducing the dust generated during crushing and preventing dust from being blown out of the feed inlet, thus affecting the health of workers. At the same time, a recovery channel is set below the feed channel to recover some of the water sprayed by the nozzles into a water tank for recycling, reducing water waste. In addition, nozzles are also installed on both sides of the discharge port. The nozzles at the discharge port control the spray volume through feedback from a dust concentration sensor installed on the discharge port. The spray volume is precisely controlled according to the dust concentration inside the crusher, which can maximize resource utilization and reduce dust suppression costs.

[0014] 2. This utility model also discloses a structure that facilitates the replacement of the liner. By opening a side opening on the side of the machine body, the liner can be installed from the side opening according to the mortise and tenon structure, which effectively reduces the difficulty of liner installation and improves work efficiency.

[0023] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, or component, but does not exclude the presence or addition of one or more other features, elements, or components.

[0024] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0025] refer to Figures 1 to 4An integrated ore crushing and spraying device includes a base 1, a body 2, crushing rollers 3, and a spraying system 5. The body 2 is mounted on the base 1. An inclined feed channel 7 is provided above the body 2. Two crushing rollers 3 are installed inside the body 2. Replaceable liners 4 are provided on both sides of the crushing rollers 3 and are installed on the inner wall of the body 2. The spraying system 5 includes a nozzle 501, a recovery channel 502, a water tank 503, and a dust concentration sensor 504. A detachable nozzle 501 is provided above the feed channel 7. An inclined recovery channel 502 is provided below the feed channel 7. A grid-like perforated opening 6 is provided at the junction of the feed channel 7 and the recovery channel 502. The nozzle 501 above the feed channel 7 is aligned with the perforated opening 6. Excess water sprayed from the nozzle 501 above the feed channel 7 through the perforated opening 6 can enter the recycling channel 502 located below the feed channel 7. The recycling channel 502 is connected to the water tank 503 on the side of the machine body 2 for water resource recycling and reuse. The water tank 503 is connected to the nozzle 501 through the pipe 505. Obviously, the system still needs external water resources, which can be supplemented by adding water resources to the water tank 503. The discharge port 8 is located at the bottom of the machine body 2. Detachable nozzles 501 are set on both sides of the discharge port 8. A dust concentration sensor 504 is installed on the side wall of the discharge port 8. The dust concentration sensor 504 provides feedback to control the spray volume of the nozzle 501. Due to the presence of the recycling channel 502, the spray volume of the nozzle 501 above the feed channel 7 can be appropriately increased. When the ore passes through the feed channel 7, it can be completely wetted by the nozzle 501 above. When it enters the two crushing rollers 3 for direct crushing, the wet surface of the ore can suppress the raising of some dust, reducing the amount of dust generated during crushing. The remaining dust is sensed by the dust concentration sensor 504 set at the discharge port 8, and the spray volume of the nozzle 501 is controlled by the feedback circuit to accurately suppress the generation of dust. This utility model can suppress the dust generated by ore crushing by initially spraying and wetting the feed channel 7 and accurately suppressing dust at the discharge port 8, thereby maximizing resource utilization and reducing dust suppression costs.

[0026] The water tank 503 includes a water storage chamber 5031, a sedimentation chamber 5032, and a drain outlet 5033. A small hole is opened on one side of the water tank 503 to connect to the recycling channel 502. A grid plate 5035 is installed inside the water tank 503, dividing the water tank 503 into an upper water storage chamber 5031 and a lower sedimentation chamber 5032. A drain outlet 5033 is provided at the bottom of the sedimentation chamber 5032. A water pump 5034 is installed inside the water storage chamber 5031. The water pump 5034 is connected to the nozzle 501 through a pipe 505. Water flowing through recycling channel 502 typically carries a large amount of silt and small minerals. The grid plate 5035 divides the water tank 503 into an upper water storage tank 5031 and a lower sedimentation tank 5032, allowing the silt and small minerals to leak into the lower sedimentation tank 5032 and not re-enter the circulation system. When the sedimentation tank 5032 accumulates a certain amount of silt, the silt and small minerals are discharged and cleaned by opening the drain outlet 5033 at the bottom of the sedimentation tank.

[0027] The machine body 2 has a side opening 201 on its side, through which the liner 4 is installed. The back of the liner 4 has a tenon-shaped groove 9, and the inner wall of the machine body 2 has a mortise-shaped groove 10. The tenon-shaped groove 9 and the mortise-shaped groove 10 are interlocked to fix the liner 4. A door panel 202 is provided on the side of the machine body 2, which is fastened to the side opening 201 by a latch 13, thus fixing the liner 4 in place. This tenon-and-mortise structure allows for quick installation and replacement of the liner 4. The door panel 202 blocks the side opening 201 to fix the liner 4, and replacement is achieved simply by opening the latch 13 on the door panel 202. This effectively reduces the difficulty of installing the liner 4 and improves work efficiency. The opening and closing door panel 202 can also be used for routine maintenance of the crusher.

[0028] The nozzle 501 is mounted on the disassembly plate 12, which is fixed to the body 2 by screws 11. By integrating the nozzle 501 on the disassembly plate 12, it is convenient to maintain and replace the nozzle 501. Specifically, by loosening the screws 11, the disassembly plate 12 can be removed to inspect the nozzle 501.

[0029] The spray nozzles 501 installed in the feed channel 7 and the spray nozzles 501 installed in the discharge port 8 control the spray volume respectively. Due to the presence of the recovery channel 502, and considering the need to quickly wet the ore surface, the spray volume of the spray nozzles 501 installed in the feed channel 7 can be appropriately increased to quickly wet the ore surface. The spray nozzles 501 installed in the discharge port 8 are adjusted by feedback from the dust concentration sensor 504, which can accurately suppress dust and reduce the waste of water resources.

[0030] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
