Description

Technical Field

[0001] The present application relates to the field of environmental treatment technology, and in particular to a dust reduction device for electrolytic aluminum raw material ore. Background Art

[0002] Electrolytic aluminum requires ore, mainly because the ore contains aluminum oxide, which is the key raw material in the electrolytic aluminum process. In the process of electrolytic aluminum, aluminum oxide is reduced to pure metallic aluminum through electrolysis. As a source of aluminum oxide, ore provides the necessary raw material basis for electrolytic aluminum.

[0003] During the ore transportation process, there will be friction between the ore and the belt, lifting bucket, coal bunker and other parts, and the ore itself will also have friction, which will generate a lot of dust. This dust will not only cause environmental pollution, but also bring the risk of dust explosion. Therefore, measures must be taken to control the generation of dust. Spraying is one of the direct, efficient and low-cost measures. It can settle the dust in the air by spraying water, thereby effectively reducing the dispersion and accumulation of dust.

[0004] In the related art, a frame is usually erected and then a water pipe is tied to the frame for spraying. Since the pipe is fixed, it cannot be adjusted according to the inclination angle of the belt, resulting in excessive water spraying in some areas, affecting the subsequent processing of the ore, and too little water spraying in some areas, resulting in poor dust reduction effect.

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Since the relevant technology cannot be adjusted according to the inclination angle of the belt, the water spraying volume in some areas is too large, affecting the subsequent processing of the ore, and the water spraying volume in some areas is too small, resulting in poor dust reduction effect.

[0028] In order to solve the above technical problems, the present application provides a dust reduction device for electrolytic aluminum raw material ore, including a first seat body 1, a second seat body 2, a lifting mechanism 3 and a pipe clamp 4.

[0029] The lifting mechanism 3 includes a movable part movably arranged on the first seat body 1, and the movable part is also connected to the second seat body 2. Through the movement of the movable part relative to the first seat body 1, the distance between the second seat body 2 and the first seat body 1 can be adjusted, thereby adjusting the height of the pipe clamp 4 to meet the transportation needs of ores of different heights.

[0030] The pipe clamp 4 is installed on the second seat body 2 and is used to install a spray water pipe (not shown in the figure). The spray water pipe is externally connected to a water supply pipe. A plurality of nozzles are arranged on the spray water pipe so that the nozzles face the ore transportation site, so that dust reduction treatment can be carried out.

[0031] In some embodiments, since different conveyor belts have different inclination heights, in order to adapt to conveyor belts with various inclination angles, in this embodiment, the position of the spray water pipe can be adjusted through the installation position of the pipe clamp 4, so that the position of each nozzle is roughly the same from the conveyor belt, thereby ensuring the uniformity of the spraying.

[0032] The pipe clamp 4 has multiple installation positions. When the pipe clamp 4 is in different installation positions, the inclination angle of the spray water pipe is different. When the inclination angle is zero, the spray water pipe is in a horizontal state. When the inclination angle is greater than zero, the spray water pipe is in an inclined state with one end higher than the other end. Since the nozzles are evenly spaced on the spray water pipe, in order to ensure the uniformity of spraying, generally speaking, the inclination angle of the spray water pipe is roughly the same as the inclination angle of the conveyor belt for transporting ore, so that the spacing from each nozzle to the conveyor belt can be roughly equal, thereby ensuring uniform spraying of the ore.

[0033] Furthermore, the movable part is a first screw rod 31, and the lifting mechanism 3 also includes a driving device 32. The first screw rod 31 is rotatably arranged on the first seat body 1. The driving device 32 is drivingly connected to the first screw rod 31 and is used to drive the first screw rod 31 to rotate around its own axis.

[0034] A threaded block is provided on the first seat body 1, the first screw rod 31 is threadedly connected to the threaded block, and the first screw rod 31 is rotationally connected to the second seat body 2, so when the first screw rod 31 rotates, the second seat body 2 will move away from the first seat body 1 to achieve the lifting function.

[0035] In some possible embodiments, lifting can be achieved by means of a cylinder jacking method, or by means of a hydraulic scissor lift mechanism.

[0036] In this application, see Figure 1 as well as Figure 2 The driving device 32 includes a driving motor 321, a housing 322, a worm gear 323 and a worm 324. The housing 322 is installed on the first seat body 1. The worm gear 323 is rotatably arranged in the housing 322, so that the worm gear 323 can only rotate around its own axis. The worm gear 324 is penetrated by the housing 322 and meshed with the worm gear 323. The driving motor 321 is driven and connected to the worm gear 324. A reducer can be set according to actual conditions to connect the driving motor 321 and the worm gear 324. The first screw 31 is penetrated by the worm gear 323 and the housing 322, and is rotatably connected to the worm gear 323.

[0037] The driving motor 321 is also installed on the first base body 1. In this way, when the driving motor 321 is running, it will drive the worm 324 to rotate. When the worm 324 rotates around itself, the worm 324 will drive the worm wheel 323 to rotate around itself. The worm wheel 323 has an internal thread, so it is threadedly connected to the first screw 31. When the worm wheel 323 rotates, the first screw 31 can be raised and lowered while rotating.

[0038] It is understandable that the rotation of the worm wheel 323 can be achieved by providing annular convex strips on its upper and lower sides and providing an annular groove in the housing 322. The worm wheel 323 can rotate around its own axis through the cooperation of the convex strips and the annular groove.

[0039] Furthermore, the lifting mechanism 3 also includes a guide rod 33, and there are multiple guide rods 33. In order to ensure stability, they are generally symmetrically arranged on both sides of the first screw rod 31. One end of the guide rod 33 is fixed on the second base body 2, and the other end is slidably connected to the first base body 1.

[0040] By setting the guide rod 33, the lifting and lowering of the second seat body 2 is relatively stable and shaking is avoided.

[0041] See also Figure 1 The first seat body 1 defines a cavity 1a, and the driving device 32 is located in the cavity 1a, which can prevent some dust or water from entering the driving device 32 and affecting the service life. It can be understood that the cavity 1a is a closed space, and the user can close or open the cavity 1a by opening a door on the side wall of the first seat body 1, so that the user can easily inspect and repair it.

[0042] In this embodiment, see Figure 1The pipe clamp 4 includes a frame 41 and a plurality of pipe clamp bodies 42 arranged on the frame 41. The frame 41 is installed on the second seat 2, and the plurality of pipe clamp bodies 42 are arranged on the frame 41 at intervals. By different installation positions of the frame 41 on the second seat 2, the inclination angles of the water pipes clamped by the pipe clamp bodies 42 can be different. The arrangement of the plurality of pipe clamp bodies 42 can ensure uniform force on the water pipes.

[0043] See also Figure 1 The frame body 41 is provided with a first slot hole 41a along its length direction, and the second seat body 2 is provided with a second slot hole 2a along the vertical direction. The pipe clamp 4 also includes a fastener, which is used to pass through the first slot hole 41a and the second slot hole 2a and connect the second seat body 2 and the frame body 41.

[0044] by Figure 1 As shown, the first slot hole 41a and the second slot hole 2a are in an interlaced cross shape. When the inclination angle of the water pipe needs to be adjusted, the first slot hole 41a and the second slot hole 2a can be crossed so that the included angle between the two is less than 90. For example, the left side of the frame 41 can be raised and the right side of the frame 41 can be lowered, or the left side of the frame 41 can be lowered and the right side of the frame 41 can be raised, depending on the specific inclination direction setting of the conveyor belt.

[0045] In this embodiment, the fasteners are bolts and nuts, which pass through the first slot 41a and the second slot 2a in sequence, and then the nuts and gaskets are used to lock the second base 2 and the frame 41. When it comes to conveyor belts with different inclination angles, you only need to loosen the nuts and then adjust the inclination angle of the frame 41 and the second base 2.

[0046] In this embodiment, the tube clamp body 42 includes a first fixing plate 421 , a first clamping member 422 , a second clamping member 423 , a second fixing plate 424 and a second screw 425 .

[0047] The first fixing plate 421 can be fixed to the second base body 2 by means of bolts or welding. The second fixing plate 424 and the second clamping member 423 can also be fixed to the first fixing plate 421 by means of bolts or welding.

[0048] The second screw 425 is passed through the second fixing plate 424 and is rotatably connected to the first clamping member 422. The second screw 425 is threadedly connected to the second fixing plate 424, wherein the first clamping member 422 and the second clamping member 423 are arranged opposite to each other, and a space for clamping the water pipe is formed between the first clamping member 422 and the second clamping member 423. By rotating the second screw 425, the first clamping member 422 can be driven to rise and fall, thereby adjusting the size of the space for clamping the water pipe.

[0049] It should be understood that the water pipe referred to in this embodiment should be a water pipe with a certain strength, such as a stainless steel water pipe, etc., which can be connected to a softer water pipe outside by a clamp or other means.

[0050] In addition, by rotating the water pipe, the water spraying direction of the nozzle on the water pipe can also be adjusted, which greatly improves the applicability of the dust suppression device in this embodiment.

[0051] Generally speaking, since the water pipe is arranged in a cylindrical shape, in this embodiment, in order to better clamp the water pipe, a slot is provided on the first clamping member 422 toward the second clamping member 423 and on the second clamping member 423 toward the first clamping member 422. Through the design of the slot, the first clamping member 422 and the second clamping member 423 can support the water pipe at multiple points to improve the stability of clamping the water pipe. The slot is a through slot, and the opening area of ​​the slot gradually decreases from the bottom of the slot to the slot mouth to accommodate water pipes of different diameters.

[0052] In some embodiments, the first clamping member 422 and the first fixed plate 421 can also be set to be slidably connected. For example, a sliding groove is opened in the first clamping member 422, and a sliding rail is set on the first fixed plate 421. The sliding groove and the sliding rail cooperate with each other, so that the first clamping member 422 will not shake when it is raised or lowered, making the clamping more stable.

[0053] In order to facilitate the mobility of the entire dust suppression device, a walking mechanism 11 is provided at the lower end of the first seat body 1. The walking mechanism 11 is preferably a universal wheel with a foot brake, which is a product currently on sale in the market, so the principle thereof is not further explained here. The arrangement of the universal wheel facilitates the transportation of the entire dust suppression device.
