Description

Technical Field

[0001] This utility model relates to the technical field of ore crushing equipment, and in particular to an ore crushing equipment that facilitates the collection of ore powder. Background Technology

[0002] Ore refers to rocks containing valuable minerals extracted from mines. During mining, the extracted ore blocks need to be crushed into smaller pieces for subsequent sorting, impurity removal, and purification processes to facilitate transportation and further processing. Currently, ore is crushed using ore crushing equipment. Ore crushing equipment is a type of machinery that crushes large solid raw materials to the required size, and it is widely used in mining, building materials, environmental protection, resource recycling, and chemical industries. Traditional ore crushing equipment first uses a conveyor belt or ore transport machinery to pour the ore into the equipment through an opening at the top. Then, a crushing motor drives two crushing rollers to rotate in opposite directions, causing the ore to be squeezed and gradually refined in the crushing gap between the rollers by the relative rotation mechanism. Finally, the ore is output from below the crushing gap, thus completing the ore crushing process.

[0003] Currently, ore crushing equipment generates a large amount of stone dust during operation due to the impact between ore particles and the resulting fragmentation. This stone dust mixes with the airflow within the crushing equipment, creating dust that escapes into the environment. However, existing ore crushing equipment lacks dust suppression structures to filter and collect the dust generated by the stone particles. This allows the dust to diffuse directly outward, increasing the dust concentration in the area where the equipment is located, leading to environmental pollution, decreased air quality, and potential health risks for operators. Furthermore, since some ores contain valuable elements, the direct diffusion of dust also results in resource waste. Utility Model Content

[0004] The purpose of this invention is to provide an ore crushing device that can improve dust suppression and reduce the harm of dust emission by transferring mineral powder dust through negative pressure suction, while also collecting mineral powder in a convenient manner. This solves the problem that existing ore crushing equipment cannot process and recycle the dust generated by the ore powder produced during the crushing process, which leads to the dust easily spreading to the external environment, polluting the environment and harming human health. Furthermore, it cannot recycle mineral powder containing high-value elements, resulting in resource waste.

[0005] The technical solution adopted by this utility model is as follows: an ore crushing device that facilitates the collection of mineral powder, including a crushing shell, two crushing rollers that can cooperate to crush the input ore inside the crushing shell, and the crushing rollers are connected to a crushing drive unit located outside the crushing shell. An inclined anti-splash ore input component is provided on the top side of the crushing shell, and a ore output component that can collect and transfer the crushed ore particles is provided at the bottom of the crushing shell. An upper dust suction module and a side dust suction module are respectively provided on the top and side surfaces of the crushing shell, and the upper dust suction module and the side dust suction module are connected to a dust suppression component that can filter dust particles in the airflow through a conveying pipeline.

[0006] According to a preferred embodiment, the upper suction module includes a first suction tube head, connecting tubes, and a porous baffle. The first suction tube head is embedded in the top surface of the pulverizing shell, and multiple connecting tubes are arranged in a dot matrix on the open end face of the first suction tube head. The porous baffle is detachably connected to the lower axial end of the connecting tubes away from the first suction tube head.

[0007] According to a preferred embodiment, the end of the first suction pipe head that extends through the pulverizing housing and extends out of the pulverizing housing is provided with a first flange port that can be connected to the conveying pipeline.

[0008] According to a preferred embodiment, the horizontal suction pipe of the side suction module is inserted into the side shell wall of the crushing housing below the crushing roller, and a curved suction pipe is connected to the air inlet end of the horizontal suction pipe. The end of the horizontal suction pipe located outside the crushing housing is connected to the conveying pipeline through a flange.

[0009] According to a preferred embodiment, the conveying pipeline includes a first inlet branch pipe connected to the first dust suction pipe head, a second inlet branch pipe connected to the exhaust horizontal pipe, a tee pipe head connecting both the first and second inlet branch pipes, and a conveying main pipe connected to the dust suppression component, wherein the tee pipe head is connected to the conveying main pipe via a centrifugal fan.

[0010] According to a preferred embodiment, the dust suppression assembly includes a dust suppression pool disposed on one side of the mineral particle output assembly and an air inlet pipe inserted into the top wall of the dust suppression pool, wherein the input end of the air inlet pipe is connected to the output end of the output main pipe; the side of the dust suppression pool is also provided with a drain port and a liquid inlet.

[0011] According to a preferred embodiment, guide bars are arranged on the inner wall of the crushing shell to limit the flow of input ore into the crushing gap between the two crushing rollers; the bottom surface of the crushing shell is also fitted with a discharge pipe for outputting the crushed ore particles.

[0012] According to a preferred embodiment, the support enclosure of the mineral particle output component is connected to the bottom of the crushing shell in a manner that enables it to provide suspended support for the crushing shell, and a transfer port is provided on one side of the support enclosure. A collection box is provided in the transfer port, which is located below the expansion inlet, and a baffle is provided on the side of the collection box.

[0013] The beneficial effects of this utility model are:

[0014] The upper and side dust suction modules provided in this application can work together using negative pressure suction to draw and transfer mineral powder from the crushing shell, thereby preventing the dust generated by the mineral powder being blown up during the crushing process from escaping outward and polluting the environment and endangering human health. This improves the environmental protection and dust reduction effect during ore crushing, controls the risk of dust pollution, and can also use dust reduction components to separate and recover mineral powder, thereby reducing the waste of mineral powder containing high-value elements and improving the mineral collection capacity during crushing production.

In some examples, because some implementation methods belong to existing or conventional technology, they are not described or are not described in detail. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

[0019] The following is a detailed explanation with reference to the accompanying drawings.

[0020] Example 1

[0021] This application provides an ore crushing device that facilitates the collection of mineral powder, which includes a crushing shell 1, a crushing roller 2, a crushing drive unit 3, a ore input component 4, a ore output component 5, an upper dust suction module 6, a side dust suction module 7, a conveying pipeline 8, and a dust suppression component 9.

[0022] according to Figure 1 and Figure 2 In one specific embodiment, the crushing housing 1 defines a crushing chamber isolated from the external environment, preventing dust hazards caused by the random diffusion of dust generated from the mixing of ore powder and air. Two crushing rollers 2 are installed inside the crushing housing 1, which cooperate to crush the input ore. The crushing rollers 2 are connected to a crushing drive unit 3 located outside the crushing housing 1, driving the two crushing rollers 2 to rotate synchronously in opposite directions. An inclined, splash-proof ore input assembly 4 is provided on the top side of the crushing housing 1. A ore particle output assembly 5 is provided at the bottom of the crushing housing 1 to collect and transfer the crushed ore particles. An upper dust suction module 6 is provided on the top surface of the crushing housing 1 to directionally suck and transfer dust particles carried by the input ore, and a side dust suction module 7 is provided on the side surface of the crushing housing 1 to collect dust particles generated when the ore is crushed into ore particles by the crushing rollers 2. The upper dust suction module 6 and the side dust suction module 7 are connected to a dust suppression assembly 9, which filters dust particles in the airflow, via a conveying pipe 8. The upper dust suction module 6 and the side dust suction module 7 provided in this application can work together to suction and transfer the mineral powder in the crushing shell 1 using negative pressure suction, thereby preventing the dust generated by the mineral powder being blown up during the crushing process from escaping outward and polluting the environment and endangering human health. This improves the environmental protection and dust reduction effect during ore crushing, controls the risk of dust pollution, and can also use the dust reduction component 9 to separate and recover the mineral powder, thereby reducing the waste of mineral powder containing high-value elements and improving the mineral collection capacity during crushing production.

[0023] Preferably, guide bars 11 are arranged on the inner wall of the crushing housing 1 to limit the flow of input ore into the crushing gap between the two crushing rollers 2. Specifically, the two guide bars 11 have arc surfaces adapted to the cylindrical surface contours of at least a portion of the crushing rollers 2, so that the two guide bars 11 can cooperate to limit the falling position of the ore. More preferably, the guide bars 11 can be fixed to the inner wall of the crushing housing 1 by welding or countersunk bolts. Preferably, a discharge port 12 for outputting crushed ore particles is also inserted into the bottom surface of the crushing housing 1. More preferably, the discharge port 12 includes a port outside the crushing housing 1 and a converging cavity structure inside the crushing housing 1, thereby enabling the collection and output of crushed ore particles, improving the centralized stacking of ore particles, avoiding splashing everywhere, and improving the collection effect of the ore particle output component 5. The discharge port 12 provided in this application can also continuously reverse the flow of air to compensate for the negative pressure formed in the crushing chamber 1 due to the directional suction of the side dust suction module 7. This maintains the stability of the air pressure and the abundance of air in the crushing chamber 1, allowing the side dust suction module 7 to continuously and effectively perform suction work and use air as a flow carrier to transfer the flying mineral powder. In addition, the upward-flowing air in the discharge port 12 can effectively prevent mineral powder dust from escaping outward from the shell gap of the mineral particle output component 5 as the mineral particles fall. The reverse airflow can suppress the escape of mineral powder from the discharge port 12, improving the dust prevention effect.

[0024] Preferably, the axial ends of the crushing roller 21 are rotatably inserted into the inner wall of the crushing housing 1 via rotating shafts 22. Preferably, a transmission gear 23 is fitted on the shaft of the rotating shaft 22 that passes through the crushing housing 1 and extends to the outside of the crushing housing 1. More preferably, at least one rotating shaft 22 is connected to the crushing drive unit 3 mounted on the outer wall of the crushing housing 1. Specifically, two sections of rotating shaft 22 on the same side of the two rollers 21 are rotatably inserted into the inner wall of the crushing housing 1, and two sections of rotating shaft 22 on the other side of the two rollers 21 pass through the shell wall of the crushing housing 1 and extend to the outside of the crushing housing 1. Two meshing transmission gears 23 are coplanarly fitted on the shafts of the two parallel rotating shafts 22 located outside the crushing housing 1. When one rotating shaft 22 rotates, the two rotating shafts 22 can rotate synchronously and in opposite directions under the constraint of the transmission gears 23, so that the two rollers 21 simultaneously rotate to drive the mineral particles to move into the crushing gap.

[0025] Preferably, the crushing drive unit 3 includes a support plate frame 31 detachably connected to the outer wall of the crushing housing 1 and a crushing rotary motor 32 mounted on the support plate frame 31. Preferably, the output shaft of the crushing rotary motor 32 is connected to the end of the rotating shaft 22 via a coupling. Preferably, the U-shaped support plate frame 31 is mounted on the outer wall of the crushing housing 1 by means of limiting screws or welding. Preferably, the crushing rotary motor 32 is positioned on the plate surface of the support plate frame 31 facing the crushing housing 1 by bolts and nuts inserted into its corner base plate and penetrating the support plate frame 31. Preferably, the crushing rotary motor 32 can be a YB3 explosion-proof series industrial crushing motor, with an adjustable power range of 0.55kW-315kW and an IP55 protection rating, suitable for flammable and explosive environments such as coal mines and chemical plants (e.g., coal gangue and ore crushing).

[0026] Preferably, the ore input assembly 4 includes an input pipe 41 inserted into the top of the crushing shell 1, an inclined pipe 42 connected to the input pipe 41, and an expansion inlet 43 connected to the inclined upper end of the inclined pipe 42 away from the input pipe 41. Preferably, the input pipe 41 is fixedly inserted into the top of the crushing shell 1 by welding. The input pipe 41, inclined pipe 42, and expansion inlet 43 provided in this application are integrally connected by welding, thereby ensuring the sealing of the cavity. The inclined pipe 42 provided in this application allows the inlet port to be misaligned with the port of the crushing shell 1, thereby preventing splashed ore particles generated during the crushing process from flying out of the expansion inlet 43 and endangering the safety of surrounding personnel.

[0027] Preferably, the support enclosure 51 of the ore particle output component 5 is connected to the bottom of the crushing shell 1 in a manner that allows for suspended support of the crushing shell 1. Preferably, a transfer port 511 is provided on one side of the support enclosure 51. Preferably, a collection box 52 is provided inside the transfer port 511, positioned below the expanding feed inlet 43, and a baffle 53 is provided on the side of the collection box 52. Preferably, a sloping edge is provided on the outside of the support enclosure 51. Preferably, rollers are provided at the bottom of the collection box 52 to facilitate the transfer of ore particles. Preferably, the baffle 53 can substantially block the expanding feed inlet 43, preventing a large amount of flying dust from escaping from the transfer port 511. Specifically, the small gap between the baffle 53 and the transfer port 511 provides an air inflow channel when there is negative pressure inside the crushing housing 1. This allows external air to be directionally input into the support enclosure 51 through the assembly gap and then into the crushing housing 1, compensating for the pressure difference inside the crushing housing 1 and maintaining internal and external pressure balance. Furthermore, the continuously output airflow prevents mineral dust from escaping through the assembly gap of the mineral particle output component 5, reducing the risk of dust overflow polluting the environment and endangering human health. Specifically, the mineral particle output component 5 provided in this application can be directly referenced from the collection structure involved in the existing patent with publication number CN217856408U. This part is prior art and will not be described in detail further.

[0028] Preferably, the upper dust suction module 6 includes a first dust suction head 61, a connecting tube 62, and a perforated baffle 63.

More preferably, multiple connecting tubes 62 are arranged in a dot matrix on the open end face of the first dust suction head 61. More preferably, the lower axial end of the connecting tube 62 away from the first dust suction head 61 is detachably connected to the perforated baffle 63. Specifically, the perforated baffle 63 is connected to the connecting tube 62 by screws that penetrate its plate and are spirally inserted into the connecting tube 62, thereby preventing ore splashed during the crushing process of the crushing roller 2 from entering the first dust suction head 61. Preferably, the end of the first dust suction head 61 that penetrates the crushing housing 1 and extends out of the crushing housing 1 is provided with a first flange port 611 that can be connected to the conveying pipeline 8. The porous baffle 63 provided in this application can be suspended below the inlet of the first dust suction head 61 through the positioning of the connecting tube 62. This prevents splashed ore from entering the first dust suction head 61 while ensuring that the dust airflow can be effectively drawn into the first dust suction head 61. This allows the dust raised by the mutual collision of the ore after input to be directionally sucked and transferred under negative pressure, reducing the concentration of dust spreading outward and reducing dust pollution and hazards.

[0029] Preferably, the horizontal suction pipe 71 of the side suction module 7 is inserted into the side shell wall of the crushing housing 1 below the crushing roller 2. Preferably, a curved suction port 72 is connected to the air inlet end of the horizontal suction pipe 71. Specifically, the end of the horizontal suction pipe 71 located outside the crushing housing 1 is connected to the conveying pipeline 8 via a flange. Preferably, an inclined baffle is connected to the upper edge of the suction port 72 to prevent falling mineral particles from entering its cavity. The suction port 72 provided in this application can suck up and transfer the mineral dust raised by the crushed mineral particles when they fall, avoiding the overflow and diffusion of mineral dust and improving the environmental friendliness of ore crushing. It can also transfer and recycle mineral particles, thereby reducing mineral dust pollution and waste.

[0030] Preferably, the conveying pipeline 8 includes a first inlet branch pipe 81 connected to the first dust suction pipe head 61, a second inlet branch pipe 82 connected to the exhaust horizontal pipe 71, a three-way connector 83 connecting both the first and second inlet branch pipes 81 and 82, and a conveying main pipe 84 connected to the dust settling assembly 9. More preferably, the three-way connector 83 is connected to the conveying main pipe 84 via a centrifugal fan 85. The centrifugal fan 85 provided in this application can generate directional airflow as needed to draw the gas in the first and second inlet branch pipes 81 and 82 towards the conveying main pipe 84, thereby directionally drawing and transferring the airflow carrying mineral powder within the crushing shell 1 to the dust settling tank 91, facilitating the separate recovery of small-diameter powder mineral materials. Preferably, the centrifugal fan 85 provided in this application can be a YP9-38S type high-pressure centrifugal fan with a power of 16-22kW and an air volume of 8000-12000m³. 3 / h, which can generate different suction air volumes by adjusting the power, thereby suctioning and transferring mineral powder of different particle sizes.

[0031] Preferably, the dust suppression component 9 includes a dust suppression tank 91 disposed on one side of the mineral particle output component 5 and an air inlet 92 inserted into the top wall of the dust suppression tank 91. More preferably, the input end of the air inlet 92 is connected to the output end of the output main pipe 84. Preferably, the side of the dust suppression tank 91 is also provided with a drain port 911 and a liquid inlet 912. Preferably, the air inlet 92 inserted into the dust suppression tank 91 is fixedly installed by welding. Preferably, the dust suppression tank 91 provided in this application contains a dust suppression liquid such as water, so that the airflow carrying mineral powder can dissolve the mineral powder in the tank liquid during the process of filling the water body, thereby achieving airflow filtration. The mineral powder filtered from the airflow can gradually settle in the dust suppression tank 91, thereby achieving environmentally friendly treatment and recycling of mineral powder dust, facilitating the subsequent collection of mineral powder using sedimentation + drying equipment to obtain high-fineness mineral powder material.

[0032] Preferably, the electrical components such as the pulverizing rotary motor 32 and the centrifugal fan 85 involved in this application are all electrically connected to the controller and the power supply. The control method of this application is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features.

As these are conventional connection methods, this application will not elaborate further on this part. Specifically, the connecting ends of the assembled components all form flange structures, and the two flange structures are connected by bolts, gaskets, or other structures.
