Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a safety device for exhaust of a powder ball mill. Background Technology

[0002] Ball mills, as key equipment for pulverizing materials after crushing, are widely used in many production industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous metal ore beneficiation, and glass ceramics. They can perform dry or wet grinding of various ores and other grindable materials.

[0003] Ball mills have a suitable operating pressure range. If the pressure inside the exhaust system is too high, the internal pressure of the ball mill will also increase. This may cause excessive pressure on components such as the mill shell and end caps, potentially leading to deformation, affecting the normal operation of the ball mill, or even causing serious consequences such as shell rupture. Therefore, we propose an exhaust safety device for powder ball mills. Utility Model Content

[0004] The purpose of this utility model is to provide a safety device for venting powder ball mills. By setting a pressure relief component, when the pressure inside the venting device body is too high, and the device is in operation but not venting, the gas will push the pressure relief rod to move away from the pressure relief plate, thereby causing the pressure relief plate to release its internal through hole, allowing the gas to flow through the through hole and be discharged through the pressure relief pipe. This avoids excessive pressure affecting the normal operation of the ball mill, or even causing serious consequences such as cylinder rupture, thus improving the safety of the device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Figures 1 to 6 A safety device for exhausting powder ball mill includes an exhaust device body 1, a connecting plate 11 fixedly connected to one side of the exhaust device body 1, a detachable purification box 2 provided at the outer end of the side of the exhaust device body 1 away from the connecting plate 11, a pressure relief pipe 3 fixedly connected to one end of the exhaust device body 1, and a filter screen 12 embedded inside the exhaust device body 1.

[0029] The pressure relief pipe 3 is equipped with a pressure relief component, and the purification box 2 is equipped with a purification component. Two connecting brackets 5 are fixedly installed on the side of the purification box 2 near the exhaust device body 1. The pressure relief component is used to avoid safety problems caused by excessive internal pressure of the device, and the purification component is used to purify the discharged gas and reduce pollution.

[0030] The pressure relief assembly includes a pressure relief rod 32. A pressure relief plate 31 is fixedly installed inside the pressure relief pipe 3. The pressure relief rod 32 passes through the pressure relief plate 31 and is slidably connected to it. An installation block 33 is fixedly installed inside the pressure relief pipe 3. A T-shaped slider 332 is slidably connected inside the installation block 33. A connecting block 333 is fixedly connected to the top of the T-shaped slider 332. The connecting block 333 is fixedly connected to the pressure relief rod 32. A second spring 331 is fixedly installed inside the installation block 33. The second spring 331 is fixedly connected to the T-shaped slider 332. When the pressure inside the exhaust device body 1 is too high, the gas will push the pressure relief rod 32 to move away from the pressure relief plate 31, thereby causing the pressure relief plate 31 to leak through its internal through-hole, allowing the gas to pass through. The flow is allowed through the through hole and discharged through the pressure relief pipe 3, thereby avoiding excessive pressure that could affect the normal operation of the ball mill or even cause serious consequences such as cylinder rupture. A connecting plate 35 is fixedly connected to one side of the connecting block 333, and a limiting block 34 is fixedly connected to the outside of the pressure relief pipe 3. A snap-fit ​​plate 36 is snapped into the top of the limiting block 34. The connecting plate 35 has a sliding groove 37 and a snap-fit ​​groove 38 inside. The snap-fit ​​plate 36 passes through the sliding groove 37 and is slidably connected to it. The snap-fit ​​plate 36 passes through the snap-fit ​​groove 38 and is snapped into it. By pulling the connecting plate 35, the snap-fit ​​plate 36 can be snapped into the limiting block 34 through the snap-fit ​​groove 38, allowing for manual pressure relief of the device and further improving the safety of the device.

[0031] The purification assembly includes multiple baffles 21, which are staggered inside the purification chamber 2. Activated carbon is filled between the baffles 21. The staggered baffles 21 extend the residence time of the gas inside the purification chamber 2, and the activated carbon purifies the gas to reduce pollution. A movable rod 51 is slidably connected inside the connecting frame 5, and the movable rod 51 engages with the exhaust device body 1. A movable plate 53 is slidably connected inside the connecting frame 5, and the movable rod 51 passes through and is fixedly connected to the movable plate 53. A spring 52 is fixedly connected to one side of the movable plate 53 and is fixedly connected to the connecting frame 5. By pulling the movable rod 51, the gas can be purified. The movable plate 53 moves and compresses the spring 52. Then, the movable rod 51 connects the purification box 2 and the exhaust device body 1. The exhaust device body 1 is rotatably connected to the inside of the shaft 14. The outer side of the shaft 14 is fixedly connected to the buffer plate 13. The buffer plate 13 can block the gas when it is discharged, prevent the gas from being discharged quickly, and prolong its residence time. A spring box 15 is fixedly installed on one side of the exhaust device body 1. The spring box 15 is fixedly connected to the shaft 14. The spring box 15 is provided with a spring. The spring box 15 can reset the shaft 14 after it is rotated without discharging gas.

[0032] The working process of this utility model is as follows:

[0033] The exhaust device body 1 is connected to the ball mill via the connecting plate 11. When the pressure inside the exhaust device body 1 is too high, and the entire device is in operation but not venting, the gas will push the pressure relief rod 32 away from the pressure relief plate 31, causing the pressure relief plate 31 to release its internal through-hole, allowing the gas to flow through the through-hole and be discharged through the pressure relief pipe 3. This avoids excessive pressure affecting the normal operation of the ball mill, or even causing serious consequences such as cylinder rupture, thus improving the safety of the device. After the pressure is released, under the action of the spring 331, the pressure relief rod 32 returns to its original position and contacts the pressure relief plate 31, and the internal cavity of the pressure relief pipe 3 is vented. The device is sealed to prevent gas leakage and further improve its safety. Simultaneously, by pulling the connecting plate 35, the locking plate 36 engages with the through-hole locking groove 38 and the limiting block 34, allowing for manual pressure relief and further enhancing safety. When gas needs to be discharged, pulling the moving rod 51 moves the moving plate 53 and compresses the spring 52. The moving rod 51 then connects the purification chamber 2 and the exhaust device body 1. The staggered baffles 21 extend the gas's residence time inside the purification chamber 2, and the activated carbon filling purifies the gas, reducing pollution.
