Description

Technical Field

[0001] This utility model relates to the field of ball mills, and more particularly to vertical ball mills. Background Technology

[0002] Vertical ball mills are suitable for grinding and dispersing materials with coarse, hard particles or those exhibiting a false thickening phenomenon. Materials ground by vertical ball mills have uniform particle size and fine particles. Vertical ball mills can also mix several materials together very evenly.

[0003] A Chinese utility model patent, CN209680239U, discloses a vertical ball mill, comprising a drive motor, a cover, an air supply fan, a rotating shaft, a grinding barrel, a screen, grinding balls, a rubber layer, a fixing rod, a discharge port, and a feed port. The screen is fixedly connected to the rotating shaft, the rubber layer covers the inner surface of the grinding barrel, and the grinding balls are placed on the screen. The screen includes screen holes and screen rods, with the screen holes evenly distributed on the screen and the screen rods passing through the center of the screen and fixed to the screen. This vertical ball mill, through its design of multiple screens with screen holes of different sizes, screen rods, and a rubber layer, allows for simultaneous grinding and screening of materials during the grinding process, and allows for continuous material addition. This not only saves grinding time but also produces materials with uniform particle size. Furthermore, the grinding balls of different sizes are primarily used to grind materials of corresponding sizes, reducing wear on the grinding media and lowering maintenance costs.

[0004] Referring to the aforementioned vertical ball mill, after grinding the material, during the discharge process, the small size of the ground particles, some even in powder form, causes dust to be emitted into the air. This dust pollutes the air and harms the health of workers. Therefore, effectively preventing dust from escaping and polluting the environment during the discharge process is a crucial issue that needs to be addressed in the design of vertical ball mills. Utility Model Content

[0005] This invention provides a vertical ball mill to better prevent dust from polluting the environment during the feeding process.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a vertical ball mill, including a support frame, wherein the main body of the vertical ball mill is fixedly disposed inside the support frame, and further comprising:

[0008] A shielding housing, which is fixedly connected to the inner wall of the support frame;

[0009] A shielding structure is disposed on the inner side of the shielding housing;

[0010] A dust-collecting structure is provided on both sides of the support frame, and the dust-collecting structure is used to collect dust inside the shielding housing.

[0011] Preferably, four support plates are fixedly connected to the side wall of the support frame, and the other side wall of each of the four support plates is fixedly connected to the main body of the vertical ball mill.

[0012] In this technical solution, the support plate supports the main body of the vertical ball mill.

[0013] Preferably, a connecting sleeve is fixedly connected to the top side wall of the shielding shell, and the connecting sleeve is fixedly connected to the side wall of the feed pipe on the main body of the vertical ball mill. Two shielding doors are rotatably connected to the front side wall of the shielding shell. Handle bracket two and connecting fastener two are fixedly connected to the side walls of the two shielding doors. Connecting fastener one is fixedly connected to the front side wall of the shielding shell, and connecting fastener one and connecting fastener two cooperate with each other.

[0014] In this technical solution, fastener one is snapped into fastener two, and the door is fixed in place.

[0015] Preferably, two baffles are fixedly connected to the bottom inner sidewall of the shielding housing, and a loading box is slidably connected between the two baffles. The top sidewall of the baffles is inclined toward the loading box, and two sliding frames and a fixing plate are fixedly connected to the top inner sidewall of the shielding housing.

[0016] In this technical solution, the loading box is used to load the processed materials.

[0017] Preferably, the shielding structure includes a support block, a sliding rod, a fixing ring, a second spring, and a pressing block. The support block is fixedly connected to the side wall of the shielding housing. The sliding rod is slidably connected to the side wall of the support block. The fixing ring is fixedly connected to the side wall of the sliding rod. One end of the second spring is fixedly connected to the fixing ring, and the other end of the second spring is fixedly connected to the support block. One end of the sliding rod is configured as an arc-shaped structure, and the pressing block is fixedly connected to the side wall of the other end of the sliding rod.

[0018] In this technical solution, when the barrier door is open, it no longer blocks the sliding rod. Spring 2 unfolds and drives the sliding rod to slide outward, which in turn moves the pressing block and the pulling rope. When the barrier door is closed, the barrier door blocks the sliding rod, the sliding rod moves backward, spring 2 is compressed, and the sliding rod drives the pressing block and the pulling rope to move backward.

[0019] Preferably, a push switch is fixedly connected to the side wall of the support block near the pressing block.

[0020] Preferably, the shielding structure includes a shielding frame, a spring, and a pull rope. The shielding frame is slidably connected inside a sliding frame. The spring and the pull rope are fixedly connected to the side wall of the shielding frame. The other end of the spring is fixedly connected to the side wall of a fixed plate. The other end of the pull rope passes through the spring and the side wall of the fixed plate and is fixedly connected to the side wall of the sliding rod.

[0021] In this technical solution, when the shielding door is opened, the pull rope is no longer under tension, the spring unfolds and pushes the shielding plate to move, so that the shielding plate moves to the bottom of the connecting sleeve, blocking the connecting sleeve and preventing the material from being discharged from the main body of the vertical ball mill. When the shielding door is closed, the pull rope moves backward, pulling the shielding plate to move away from the bottom of the connecting sleeve. The spring is compressed, the bottom of the connecting sleeve is opened, and the material is discharged.

[0022] Preferably, the top sidewall of the shielding frame is attached to the bottom sidewall of the connecting sleeve.

[0023] Preferably, the vacuuming structure includes a vacuum housing, a collection box, a ventilation pipe, a handle bracket, an exhaust fan, a dust filter, and a vacuum hose. The vacuum housing is fixedly connected to the side walls on both sides of the support frame. A dust filter is fixedly connected to the inner side wall of the vacuum housing.

A ventilation pipe is fixedly connected to the top side wall of the vacuum housing. An exhaust fan is fixedly connected to the inner side wall of the ventilation pipe. A vacuum hose is fixedly connected to the side wall where the vacuum housing and the support frame are connected.

[0024] In this technical solution, the exhaust fan is powered on and rotates to draw in dust, which is then drawn in by the suction pipe. This process removes dust that is raised inside the shielding housing, preventing unsettled dust from escaping when the shielding housing is opened, thus avoiding environmental pollution and harm to workers' health. The collected dust enters the suction housing through the suction pipe and falls into the collection box for collection. The dustproof net prevents dust from entering the exhaust fan.

[0025] Preferably, the exhaust fan and the push switch are electrically connected, and the suction pipe and the internal cavity of the shielding housing are connected.

[0026] In this technical solution, when the push switch is pressed, the exhaust fan is powered on and rotates to ventilate; when the push switch is released, the exhaust fan is powered off and stops ventilating.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. The enclosure and door form a closed structure to prevent dust from being emitted during the material feeding process.

[0030] 2. When the shield door is opened by the handle frame two, spring two unfolds and drives the sliding rod to slide outward. The sliding rod drives the pull rope to move, and spring one unfolds and pushes the shield plate to move, so that the shield plate moves to the bottom of the connecting sleeve to block the material from being discharged from the vertical ball mill body. When the shield door is closed, connecting fastener one is engaged in connecting fastener two, the shield door is fixed, the sliding rod moves backward, driving the pull rope to move backward, and the pull rope pulls the shield plate to move away from the bottom of the connecting sleeve. The bottom of the connecting sleeve is opened to allow material to be discharged. This allows for better sealing and opening of the bottom of the connecting sleeve while the shield door is being opened and closed, facilitating the replacement of the material box.

[0031] 3. When the shield door is opened, the pressing block moves to press the pressing switch. When the pressing switch is pressed, the exhaust fan is powered on and rotates to draw in dust, which is then sucked up by the suction pipe. This helps to prevent unsettled dust from escaping from the shield shell when the material box is opened for replacement, thus avoiding environmental pollution and harm to workers' health.

[0041] The dust suction structure 6 is disposed on both sides of the support frame 1, and the dust suction structure 6 sucks up the dust inside the shielding shell 5.

[0042] Four support plates 3 are fixedly connected to the side wall of the support frame 1, and the other side wall of each of the four support plates 3 is fixedly connected to the vertical ball mill body 2.

[0043] The support plate 3 supports the main body 2 of the vertical ball mill.

[0044] A connecting sleeve 4 is fixedly connected to the top side wall of the shielding housing 5. The connecting sleeve 4 is fixedly connected to the side wall of the feed pipe on the main body 2 of the vertical ball mill. Two shielding doors 7 are rotatably connected to the front side wall of the shielding housing 5. A second handle bracket 8 and a second connecting fastener 16 are fixedly connected to the side wall of the two shielding doors 7. A first connecting fastener 15 is fixedly connected to the front side wall of the shielding housing 5. The first connecting fastener 15 and the second connecting fastener 16 cooperate with each other.

[0045] Connecting fastener 15 is snapped into connecting fastener 2 16, and the blocking door 7 is fixed in place.

[0046] Two baffles 11 are fixedly connected to the bottom inner side wall of the shielding housing 5, and a loading box 10 is slidably connected between the two baffles 11. The top side wall of the baffles 11 is inclined toward the loading box 10. Two sliding frames 13 and a fixing plate 14 are fixedly connected to the top inner side wall of the shielding housing 5.

[0047] The loading box 10 is used to load the processed materials.

[0048] The shielding structure 9 includes a support block 911, a sliding rod 912, a fixing ring 913, a second spring 914, and a pressing block 915. The support block 911 is fixedly connected to the side wall of the shielding housing 5. The sliding rod 912 is slidably connected to the side wall of the support block 911. The fixing ring 913 is fixedly connected to the side wall of the sliding rod 912. One end of the second spring 914 is fixedly connected to the fixing ring 913, and the other end of the second spring 914 is fixedly connected to the support block 911. One end of the sliding rod 912 is configured as an arc-shaped structure, and the pressing block 915 is fixedly connected to the side wall of the other end of the sliding rod 912.

[0049] When the barrier door 7 is opened, it no longer blocks the sliding rod 912. The second spring 914 unfolds, causing the sliding rod 912 to slide outward, which in turn moves the pressing block 915 and the pulling rope 903. When the barrier door 7 is closed, it blocks the sliding rod 912, causing the sliding rod 912 to move backward. The second spring 914 is compressed, and the sliding rod 912 causes the pressing block 915 and the pulling rope 903 to move backward.

[0050] A push switch 12 is fixedly connected to the side wall of the support block 911 near the push block 915.

[0051] The shielding structure 9 includes a shielding frame 901, a spring 902, and a pull rope 903. The shielding frame 901 is slidably connected inside the sliding frame 13. The spring 902 and the pull rope 903 are fixedly connected to the side wall of the shielding frame 901. The other end of the spring 902 is fixedly connected to the side wall of the fixing plate 14. The other end of the pull rope 903 passes through the spring 902 and the side wall of the fixing plate 14 and is fixedly connected to the side wall of the sliding rod 912.

[0052] When the shielding door 7 is opened, the pull rope 903 is no longer under tension, and the spring 902 unfolds to push the shielding plate 11 to move, so that the shielding plate 11 moves to the bottom of the connecting sleeve 4 to shield the connecting sleeve 4 and block the material from being discharged from the vertical ball mill body 2. When the shielding door 7 is closed, the pull rope 903 moves backward, and the pull rope 903 pulls the shielding plate 11 to move away from the bottom of the connecting sleeve 4. The spring 902 is compressed, and the bottom of the connecting sleeve 4 is opened to allow material to be discharged.

[0053] The top sidewall of the shield 901 is attached to the bottom sidewall of the connecting sleeve 4.

[0054] The vacuuming structure 6 includes a vacuum housing 601, a collection box 602, a ventilation pipe 603, a handle bracket 604, an exhaust fan 605, a dustproof net 606, and a vacuuming pipe 607. The vacuum housing 601 is fixedly connected to the side walls on both sides of the support frame 1. A dustproof net 606 is fixedly connected to the inner side wall of the vacuum housing 601. The collection box 602 is slidably connected to the inner side wall of the vacuum housing 601. A handle bracket 604 is fixedly connected to the front side wall of the collection box 602. The ventilation pipe 603 is fixedly connected to the top side wall of the vacuum housing 601. An exhaust fan 605 is fixedly connected to the inner side wall of the ventilation pipe 603. The vacuuming pipe 607 is fixedly connected to the side wall where the vacuum housing 601 connects to the support frame 1.

[0055] When the exhaust fan 605 is powered on, it rotates to draw in dust, causing the suction pipe 607 to suck up the dust that rises inside the shield housing 5. This prevents unsettled dust from escaping the shield housing 5 when it is opened, thus avoiding environmental pollution and harm to workers' health. The sucked-up dust enters the suction housing 601 through the suction pipe 607 and falls into the collection box 602 for collection. The dustproof net 606 prevents dust from entering the exhaust fan 605.

[0056] The exhaust fan 605 is electrically connected to the push switch 12, and the suction pipe 607 is connected to the internal cavity of the shielding housing 5.

[0057] When the push switch 12 is pressed, the exhaust fan 605 is powered on and starts to rotate to ventilate. When the push switch 12 is released, the exhaust fan 605 is de-powered and stops ventilating.

[0058] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. The material to be ground is placed inside the vertical ball mill body 2 for processing. The processed material is discharged through the discharge pipe at the bottom of the vertical ball mill body 2. The material enters the shield housing 5 through the connecting sleeve 4 and falls into the material box 10 for collection. When the material box 10 is full, the connecting fastener 15 and connecting fastener 2 16 are separated. When the shield door 7 is pulled open by the handle 2 8, the shield door 7 rotates and opens. The shield door 7 no longer blocks the sliding rod 912. The spring 2 914 unfolds and drives the sliding rod 912 to slide outward, which drives the pressing block 915 and the pulling rope 903 to move. The pulling rope 903 is no longer under tension. The spring 1 902 unfolds and pushes the shield plate 11 to move, so that the shield plate 11 moves to the bottom of the connecting sleeve 4 and blocks the material discharge of the vertical ball mill body 2.

[0059] The material feeding of the vertical ball mill body 2 can be blocked simultaneously when the shielding door 7 is opened. The pressing block 915 can be moved to press the pressing switch 12. When the pressing switch 12 is pressed, the exhaust fan 605 is powered on and rotates to exhaust air, so that the dust suction pipe 607 can suck up the dust raised inside the shielding shell 5. This prevents the unsettled dust from escaping the shielding shell 5 when it is opened, thus avoiding environmental pollution and harm to the health of workers. The sucked-up dust enters the dust suction shell 601 through the dust suction pipe 607 and falls into the collection box 602 for collection. The dustproof net 606 can prevent dust from entering the exhaust fan 605.

[0060] Pull out the material-filled loading box 10, replace it with an empty material-filled loading box 10, close the shielding door 7, and snap the connecting fastener 15 into the connecting fastener 2 16. The shielding door 7 is fixed and the shielding door 7 presses against the sliding rod 912. The sliding rod 912 moves backward, the spring 2 914 is compressed, the sliding rod 912 drives the pressing block 915 and the pulling rope 903 to move backward, the pulling rope 903 pulls the shielding plate 11 to move away from the bottom of the connecting sleeve 4, the spring 1 902 is compressed, the bottom of the connecting sleeve 4 is opened, and the material is unloaded.

[0061] Press block 915 moves away from press switch 12, press switch 12 pops up, exhaust fan 605 is de-energized and stops exhausting, preventing excessive material from being sucked into dust collection housing 601 during the feeding process. The shield housing 5 and shield door 7 form a closed structure, which can prevent dust from being blown out during the feeding process.
