Description

Technical Field

[0001] The invention relates to the field of mining technology, and particularly relates to a large ore crushing mechanism for intelligent mining engineering and a using method thereof. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties, and can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are commonly expressed in percentages.

[0003] The Chinese Patent Network discloses a multi-stage ore crusher with a dust-proof function, and its patent publication number is "CN108927259A". This device mainly realizes the synchronous start and stop of crushing and dust prevention by installing an air inlet pipe and a high-pressure fan, thereby avoiding the continuous operation of the high-pressure fan and causing energy waste, achieving the purpose of energy conservation and emission reduction. However, this invention has the following disadvantages when crushing hematite: First, a large amount of dust generated during the crushing process is likely to cause environmental pollution, and at the same time, it is impossible to screen out too fine dust, which affects subsequent ore processing. Secondly, the sulfur content of hematite ore is relatively high, and a subsequent desulfurization link is required, and a large amount of water resources are needed to wash the hematite ore.

[0007] Preferably, the transmission assembly consists of a transmission sleeve plate, a first transmission shaft, a first transmission plate, a second transmission shaft, a third transmission shaft, a second transmission plate, a fourth transmission shaft, a shaft, and a transmission rod. The eccentric disk is rotatably connected to the transmission sleeve plate through it. The first transmission shaft is fixedly connected to the inner wall of the upper housing. The first transmission shaft is rotatably connected to the first transmission plate. The two ends of the second transmission shaft are respectively rotatably connected to the first transmission plate and the transmission sleeve plate.

[0008] Preferably, the dust reduction assembly consists of a piston rod, a piston cylinder, a fixing plate, a water inlet pipe, a water outlet pipe, and an atomizing nozzle. The fixing plate is fixedly connected to the inner wall of the upper housing. The piston cylinder is fixedly connected to the fixing plate.

One end of the water outlet pipe is connected to the piston cylinder, and the other end is connected to the atomizing nozzle. The atomizing nozzle is fixedly connected to the upper end of the upper housing.

[0009] Preferably, a fifth transmission shaft is rotatably connected to the lower end of the transmission rod. A transmission block is rotatably connected to the fifth transmission shaft. The transmission block is fixedly connected to the piston rod. A second transmission rod is fixedly connected to the side wall of the transmission block. A sliding rod is fixedly connected to the lower end of the second transmission rod. The sliding rod penetrates and is slidably connected to the water tank.

The vibrating screen is fixedly connected to the transmission connecting plate. A plurality of densely distributed screening holes are opened at the upper end of the vibrating screen.

[0011] The usage method of the above-mentioned large ore crushing mechanism for intelligent mining engineering includes the following steps; S1. Preparation stage: Before starting work, inject an appropriate amount of lime water into the water tank. The lime water is used for desulfurization and dust reduction of hematite. At the same time, ensure that the collection box is installed in the groove at the lower end of the lower housing to collect the finer dust screened out subsequently; S2. Ore crushing: Start the motor. The motor drives the pulley to rotate through the belt. The rotation of the rotating shaft drives the eccentric disk to perform eccentric motion. The eccentric motion of the eccentric disk causes the lower jaw plate to swing reciprocally. The upper jaw plate cooperates with the reciprocally swinging lower jaw plate to squeeze and crush the ore input from the top. S3. Dust reduction component works: The eccentric rotation of the eccentric disk drives the transmission sleeve plate to perform corresponding swinging and moving, and then drives the movement of the second transmission plate through the transmission sleeve plate. The movement of the second transmission plate drives the fourth transmission shaft and then drives the transmission rod to swing around the axis, so as to drive the piston rod to slide up and down on the inner wall of the piston cylinder by driving the transmission block. At this time, a negative pressure is generated in the piston cylinder by the piston rod, so as to transport the lime water in the water tank to the atomizing nozzle through the water inlet pipe and the water outlet pipe. The atomizing nozzle atomizes the lime water and sprays it onto the crushing area in the upper shell. At the same time, the movement of the transmission block will also drive the sliding rod to slide up and down in the water tank through the second transmission rod. The sliding rod drives the stirring blade to reciprocate, so as to stir the lime water in the water tank and prevent the lime water from precipitating. S4. Screening: The movement of the transmission sleeve plate is transmitted to the vibrating screen through the transmission connecting plate, so that the vibrating screen generates high-frequency vibration. The crushed ore particles fall on the vibrating screen. The finer dust falls through the densely distributed sieve holes at the upper end of the vibrating screen, enters the lower shell and finally falls into the collection box, realizing the separation and screening of dust and larger particle ores. As the continuous work progresses, the collection box is pulled out from the slot at the lower end of the lower shell to clean the collected dust. At the same time, the remaining amount of lime water in the water tank can be supplemented or replaced.

[0012] The invention has the following beneficial effects: 1. This mechanism adopts a crushing method with the cooperation of the upper jaw plate and the lower jaw plate. The lower jaw plate is driven to swing reciprocally by the rotating shaft driving the eccentric disk, which can efficiently squeeze and crush large pieces of ore. At the same time, it drives the sulfur and dust reduction component to transport the lime water in the water tank to the atomizing nozzle through the water inlet pipe and the water outlet pipe for atomizing spraying. The lime water can not only effectively reduce the dust flying generated during the crushing process and play a role in dust reduction, but also chemically react with the sulfur component in the hematite to achieve the purpose of sulfur reduction. While reducing environmental pollution, it also reduces the waste of water resources in the subsequent ore washing and desulfurization links.

[0013] 2. The transmission block drives the sliding rod and the stirring blade to stir the lime water in the water tank through the second transmission rod, preventing the lime water from precipitating, ensuring the uniformity of the lime water concentration, and further improving the effects of dust reduction and sulfur reduction.

[0014] 3. The precise screening and dust collection screening component drives the transmission connecting plate through the transmission sleeve plate, causing the vibrating screen to generate high-frequency vibrations. The crushed ore particles fall on the vibrating screen, and the finer dust falls through the screen holes, enters the lower housing, and drops into the collection box, realizing the separation and screening of dust and larger particle ores, avoiding the accumulation of dust in the equipment and affecting the normal operation of the equipment. At the same time, it is also convenient for subsequent treatment of the collected dust, improving the cleanliness and work efficiency of the entire mining project. Brief Description of the Drawings

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Embodiment 1

[0018] Referring to Figures 1-5 , a large ore crushing mechanism for an intelligent mining project and its usage method, including an upper housing 1, a lower housing 401, a transmission component, a dust reduction component, and a screening component: A groove is formed at the lower end of the lower housing 401. The lower housing 401 is slidably connected with a collection box 11 through the groove. The upper housing 1 is fixedly connected with the lower housing 401. An upper jaw plate 4 is fixedly connected to the inner wall of the upper housing 1. Rotating shafts 201 are respectively rotatably connected to the inner walls on both sides of the upper housing 1. The rotating shafts 201 penetrate through the upper housing 1. A pulley 2 is fixedly connected to one end of the rotating shaft 201, and an eccentric disc 202 is fixedly connected to the other end. The end of the eccentric disc 202 away from the rotating shaft 201 penetrates through and is rotatably connected with a lower jaw plate 3; The transmission assembly is used to drive the dust reduction assembly and the screening assembly; The dust reduction assembly is used for dust reduction; The screening assembly is used for screening finer dust.

[0019] A water tank 6 is fixedly installed at the lower end of the inner wall of the upper housing 1. A connecting block 7 is fixedly connected to the inner wall of the upper housing 1. A rotating shaft 8 is rotatably connected to the connecting block 7. The rotating shaft 8 penetrates through the connecting block 7. A support plate 9 is rotatably connected to the rotating shaft 8. A hydraulic cylinder 10 is fixedly connected to the support plate 9. The piston end of the hydraulic cylinder 10 is fixedly connected to the lower jaw plate 3. It should be noted that the surfaces of the lower jaw plate 3 and the upper jaw plate 4 are provided with wavy liners made of high manganese steel, so as to enhance the crushing effect.

[0020] In this embodiment, when the external motor is started, the motor drives the pulley 2 to rotate. Since the pulley 2 is fixedly connected to the rotating shaft 201, the pulley 2 will drive the rotating shaft 201 to rotate. The rotation of the rotating shaft 201 drives the eccentric disc 202 to perform an eccentric motion. The eccentric motion of the eccentric disc 202 causes the lower jaw plate 3 to perform a reciprocating swing. At this time, the upper jaw plate 4 cooperates with the reciprocating swing of the lower jaw plate 3. When large pieces of ore are put into the upper housing 1 from the top, under the extrusion and grinding action between the two, the large pieces of ore are gradually broken into small pieces. At the same time, the hydraulic cylinder 10 can assist the movement of the lower jaw plate 3 through telescoping, making the effect of crushing the ore better. Embodiment Two

[0021] Further, referring to Figures 1-5, in this embodiment, the transmission assembly consists of a transmission sleeve plate 203, a first transmission shaft 101, a first transmission plate 102, a second transmission shaft 103, a third transmission shaft 104, a second transmission plate 105, a fourth transmission shaft 106, a shaft 107, and a transmission rod 108. The eccentric disk 202 is rotatably connected through the transmission sleeve plate 203. The first transmission shaft 101 is fixedly connected to the inner wall of the upper housing 1. The first transmission shaft 101 is rotatably connected to the first transmission plate 102. The two ends of the second transmission shaft 103 are respectively rotatably connected to the first transmission plate 102 and the transmission sleeve plate 203. The two ends of the third transmission shaft 104 are respectively rotatably connected to the transmission sleeve plate 203 and the second transmission plate 105. The fourth transmission shaft 106 is respectively rotatably connected to the second transmission plate 105 and the transmission rod 108. The shaft 107 is fixedly connected to the inner wall of the upper housing 1. The shaft 107 is rotatably connected to the transmission rod 108.

[0022] The dust reduction assembly consists of a piston rod 601, a piston cylinder 602, a fixing plate 603, a water inlet pipe 604, a water outlet pipe 605, and an atomizing nozzle 5. The fixing plate 603 is fixedly connected to the inner wall of the upper housing 1. The piston cylinder 602 is fixedly connected to the fixing plate 603. The piston rod 601 is slidably connected to the inner wall of the piston cylinder 602. One end of the water inlet pipe 604 is fixedly connected to the water tank 6, and the other end is fixedly connected to the piston cylinder 602. One end of the water outlet pipe 605 is connected to the piston cylinder 602, and the other end is fixedly connected to the atomizing nozzle 5. The atomizing nozzle 5 is fixedly connected to the upper end of the upper housing 1. It should be noted that the water tank 6 stores lime water, so that sulfur can be reduced in the hematite while reducing dust, thereby reducing the time and waste of water resources for subsequent ore washing. It should be noted that one-way valves are installed in both the water outlet pipe 605 and the water inlet pipe 604 to prevent water from flowing back.

[0023] Furthermore, in this embodiment, in addition to driving the lower jaw plate 3 to move to achieve ore crushing, the rotation of the eccentric disk 202 also drives the transmission assembly, and then drives the dust reduction assembly to work. The specific transmission process is as follows: The eccentric rotation of the eccentric disk 202 drives the transmission sleeve plate 203 to make corresponding swinging and moving. The movement of the transmission sleeve plate 203 drives the first transmission plate 102 to swing around the first transmission shaft 101 through the second transmission shaft 103. The movement of the transmission sleeve plate 203 drives the second transmission plate 105 to move through the third transmission shaft 104. The movement of the second transmission plate 105 drives the transmission rod 108 to swing around the shaft 107 through the fourth transmission shaft 106. A fifth transmission shaft 109 is rotatably connected to the lower end of the transmission rod 108. A transmission block 110 is rotatably connected to the fifth transmission shaft 109. The swinging of the transmission rod 108 drives the piston rod 601 to slide up and down on the inner wall of the piston cylinder 602 through the fifth transmission shaft 109 and the transmission block 110. Since the fifth transmission shaft 109 and the transmission block 110 are rotatably connected, the swinging of the transmission rod 108 does not block the piston rod 601 from sliding up and down on the inner wall of the piston cylinder 602.

[0024] When the piston rod 601 slides upward, a negative pressure is formed in the piston cylinder 602, and the lime water in the water tank 6 is sucked into the piston cylinder 602 through the water inlet pipe 604; when the piston rod 601 slides downward, the lime water in the piston cylinder 602 is squeezed and transported to the atomizing nozzle 5 through the water outlet pipe 605. The atomizing nozzle 5 atomizes the lime water and sprays it onto the crushing area in the upper housing 1 to achieve the functions of dust reduction and sulfur reduction. Embodiment III

[0025] Further, referring to Figures 4-6 , in this embodiment, the lower end of the transmission rod 108 is rotatably connected to a fifth transmission shaft 109. The fifth transmission shaft 109 is rotatably connected to a transmission block 110. The transmission block 110 is fixedly connected to the piston rod 601. A second transmission rod 111 is fixedly connected to the side wall of the transmission block 110. The lower end of the second transmission rod 111 is fixedly connected to a sliding rod 112. The sliding rod 112 penetrates and is slidably connected to the water tank 6. One end of the sliding rod 112 away from the second transmission rod 111 is fixedly connected to a stirring blade 113. The screening assembly includes a transmission connecting plate 204 and a vibrating screen 205. The connecting plate 204 is fixedly connected to the transmission sleeve plate 203. The vibrating screen 205 is fixedly connected to the transmission connecting plate 204. A plurality of densely distributed screening holes 206 are formed in the upper end of the vibrating screen 205. It should be noted that the size of the screening holes 206 is about 3 mm, and the apertures of this size can play a role in preliminary screening.

[0026] In this embodiment, the movement of the transmission block 110 will also drive the sliding rod 112 to slide up and down in the water tank 6 through the second transmission rod 111. The sliding rod 112 drives the stirring blade 113 to reciprocate, so as to stir the lime water in the water tank 6 by the stirring blade 113, prevent the lime water from precipitating, and ensure the uniformity of the lime water concentration; at the same time, the movement of the transmission sleeve plate 203 is transmitted to the vibrating screen 205 through the transmission connecting plate 204, so that the vibrating screen 205 generates high-frequency vibration. The crushed ore particles fall on the vibrating screen 205, and the finer dust including the product of the reaction between the lime water and the ore falls through the densely distributed screening holes 206 at the upper end of the vibrating screen 205, enters the lower housing 401 and finally falls into the collection box 11, realizing the separation and screening of dust and larger particle ores.

[0027] The usage method of the above-mentioned large ore crushing mechanism for intelligent mining engineering includes the following steps; S1. Preparation stage: Before starting work, inject an appropriate amount of lime water into the water tank 6. The lime water is used for sulfur reduction and dust reduction of hematite. At the same time, ensure that the collection box 11 is installed in the slot at the lower end of the lower housing 401 for subsequent collection of the finer dust screened out; S2. Ore crushing: Start the motor. The motor drives the pulley 2 to rotate through the belt. The rotation of the rotating shaft 201 drives the eccentric disk 202 to perform eccentric motion. The eccentric motion of the eccentric disk 202 causes the lower jaw plate 3 to perform reciprocating swing. The upper jaw plate 4 cooperates with the reciprocating swing of the lower jaw plate 3 to squeeze and crush the ore input from the top. S3. Dust reduction component works: The eccentric rotation of the eccentric disk 202 drives the transmission sleeve plate 203 to perform corresponding swing and movement. Then, through the transmission sleeve plate 203, it drives the movement of the second transmission plate 105. Through the movement of the second transmission plate 105, it drives the fourth transmission shaft 106 and then drives the transmission rod 108 to swing around the shaft 107. Thus, by driving the transmission block 110, it drives the piston rod 601 to slide up and down on the inner wall of the piston cylinder 602. At this time, a negative pressure is generated in the piston cylinder 602 by the piston rod 601. Thereby, the lime water in the water tank 6 is transported to the atomizing nozzle 5 through the water inlet pipe 604 and the water outlet pipe 605. The atomizing nozzle 5 atomizes the lime water and sprays it onto the crushing area in the upper housing 1. At the same time, the movement of the transmission block 110 will also drive the sliding rod 112 to slide up and down in the water tank 6 through the second transmission rod 111. The sliding rod 112 drives the stirring blade 113 to perform reciprocating motion. Thus, the stirring blade 113 stirs the lime water in the water tank 6 to prevent the lime water from precipitating. S4. Screening: The movement of the transmission sleeve plate 203 is transmitted to the vibrating screen 205 through the transmission connecting plate 204, causing the vibrating screen 205 to generate high-frequency vibration. The crushed ore particles fall on the vibrating screen 205. The finer dust falls through the densely distributed screen holes 206 at the upper end of the vibrating screen 205, enters the lower housing 401 and finally falls into the collection box 11, realizing the separation and screening of dust and larger particle ores. As the continuous work progresses, the collection box 11 is pulled out from the slot at the lower end of the lower housing 401 to clean the dust collected therein. At the same time, the remaining amount of lime water in the water tank 6 can be supplemented or replaced as needed.

[0028] The above is only a preferred specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the invention, according to the technical solution of the invention and its inventive concept, makes equivalent substitution or change, and should be covered within the protection scope of the invention.

At the same time, the movement of the transmission block (110) drives the sliding rod (112) to slide up and down in the water tank (6) through the second transmission rod (111). The sliding rod (112) drives the stirring blade (113) to reciprocate, thereby causing the stirring blade (113) to stir the lime water in the water tank (6) to prevent the lime water from settling. S4, screening: The movement of the transmission sleeve (203) is transmitted to the vibrating screen (205) through the transmission connecting plate (204), causing the vibrating screen (205) to generate high-frequency vibrations, and the crushed ore particles fall on the vibrating screen (205). The finer dust falls through the densely distributed sieve holes (206) at the upper end of the vibrating screen (205), enters the lower shell (401) and finally falls into the collecting box (11), thereby achieving separation and screening of the dust and larger particles of ore. As the work continues, the collecting box (11) is pulled out of the groove at the lower end of the lower shell (401) to clean the dust collected therein. At the same time, the lime water in the water tank (6) can be replenished or replaced according to the remaining amount.
