Technical Field
[0001] This utility model relates to the field of dust removal technology, specifically to a dust removal device for ore screening. Background Technology
[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. It can be divided into metallic minerals and non-metallic minerals. Ore screening machines are a common type of equipment used to screen ores. They can separate fine impurities and particles from the ore. However, a lot of dust is generated during the ore screening process. This dust can damage and pollute human health and the atmospheric environment. Therefore, a dust removal device for ore screening is needed.
[0003] A search revealed existing dust removal technologies for ore screening, including a dust removal device for ore screening machines. This device comprises a dust collection box with a movable door on its left side wall. Inside, there are grading dust collection filter elements, each containing three dust collection plates. Each of the three dust collection plates has evenly distributed dust collection holes, with the inner diameter of the holes decreasing from top to bottom. Impurities and dust pass through the three dust collection plates sequentially, achieving multi-stage dust removal. An electric hydraulic lifting cylinder allows for height adjustment of one side of the dust collection plates. The operator opens the movable door to allow for grading... After cleaning, the impurities on the dust collector filter can be discharged to the outside, which facilitates dust removal and reduces the labor intensity of the workers. However, in the process of multi-stage dust removal, if the radius of the dust particles entering the graded dust collector filter is larger than the inner diameter of the top dust collector plate, the dust will remain on the top dust collector plate and wait to be removed. Since the dust removal device is working continuously during the ore screening process, this will cause too many large dust particles to accumulate on the top dust collector plate. If this dust is not removed in time, it will affect the subsequent multi-stage dust removal effect. Utility Model Content
[0004] This invention proposes a dust removal device for ore screening, which solves the problem in the prior art where large particles of dust clog the dust removal plate, affecting the classification and dust removal of dust entering the dust removal box.
[0005] The technical solution of this utility model is as follows: A dust removal device for ore screening, comprising a dust removal box body, the dust removal box body including: a feed inlet, a dust suction pipe, three dust removal plates and an atomizing component, the filter holes of the three dust removal plates decreasing in size from top to bottom, and further comprising: A fan is installed on the dust collection box body, and the output end of the fan is connected to the dust suction pipe for sucking dust and impurities in the ore screening machine into the dust collection box body; A vibration mechanism is installed inside the dust collector box and is used to vibrate the three dust collector plates up and down. The slag scraping assembly includes three slag scraping assemblies, which are respectively disposed on three dust removal plates and used to remove dust and debris from the three dust removal plates to one side of the dust removal plates. A collection component for collecting dust and debris from the three dust collection plates.
[0006] Preferably, the vibration mechanism includes: A fixing plate 1, one end of which is fixedly connected to one end of the three dust removal plates; Fixed plate two is fixedly connected to the other end of the three dust removal plates, and two discharge windows are opened on fixed plate two; A vibration motor is mounted on the other end of the fixed plate. Two elastic elements are fixedly connected to the bottom of both the first and second fixing plates, and the bottom end of each elastic element is fixedly connected to the bottom of the inner part of the dust collector body.
[0007] Preferably, the elastic element includes: Support plates, two of which are symmetrically arranged and respectively fixedly connected to the second fixed plate and the inner bottom wall of the dust collector body; A spring, the two sides of which are respectively fixedly connected to the two support plates.
[0008] Preferably, the slag scraper assembly includes: Four limiting blocks, two of which are fixedly connected to one end of the first fixed plate and two of which are fixedly connected to one end of the second fixed plate; Two electric guide rods, with their two ends respectively fixedly connected to the two limiting blocks; Two electrically operated sliding sleeves are fitted onto the electrically operated guide rod; The scraper, with its two ends fixedly connected to the two electric sliding sleeves respectively; A cleaning brush, which is fixedly connected to the bottom end of the scraper.
[0009] Preferably, the collection components include: A collection trough is slidably connected to the dust collector box. The collection trough is located at the bottom of the dust collector box, and a handle is fixedly connected to the side wall of the collection trough. A collection box is fixedly connected to one side wall of the dust collector, and the collection box has a movable door and a sliding groove. A baffle is slidably connected to the collection box, and a handle is fixedly connected to the side wall of the baffle.
[0010] Preferably, each of the dust removal plates maintains an inclined angle.
[0011] The working principle and beneficial effects of this utility model are as follows: In this invention, a blower is used to transfer the dust generated during the vibration screening of ore to a dust collection box to prevent dust from escaping and affecting the working environment. Dust falls onto the dust collection plate through one end of the suction pipe. By setting an atomizing component above the dust collection plate, the dust is squeezed into the dust collection box and dispersed above the dust collection plate. The atomizing component atomizes the dust, causing the dispersed dust to settle onto the dust collection plate for dust removal. By incorporating a vibration mechanism, the dust on the dust collector plate is slightly vibrated up and down, preventing large dust particles from clogging the plate and hindering the subsequent grading and dust removal of smaller dust particles. A baffle is installed on one side of the collection box, blocking the two discharge windows from the collection box when dust removal is not stopped. This prevents ungraded dust from vibrating and rolling directly into the collection box, affecting the grading and dust removal effect. After dust removal is completed, a scraper assembly removes the dust adhering to the dust collector plate and the dust accumulated at the two discharge windows into the collection box. The dust in the collection trough and collection box is then cleaned. This completes the grading and dust removal process, preventing large dust particles from clogging the dust collector plate and affecting the grading and dust removal of subsequent dust entering the dust collector.

Detailed Implementation
[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0016] like Figures 1-6 As shown, this embodiment proposes a dust removal device for ore screening, including a dust removal box body 1. The dust removal box body 1 includes: a feed inlet 2, a dust suction pipe 3, three dust removal plates 4 and an atomizing component. The filter holes of the three dust removal plates 4 decrease in size from top to bottom. It also includes a fan 5, a vibration mechanism, a slag scraping component and a collection component. Considering the screening of ore, operators usually choose to use vibration screening, which will separate ore and debris of different sizes. During this process, dust inevitably floats and escapes inside the screening machine, which can cause the operator to inhale the dust and harm their health, and will also deteriorate the working environment. Therefore, dust removal equipment is needed to remove dust during ore screening. The dust inside the screening machine can be transferred to the dust removal equipment body by the fan 5. The fan 5 is installed on the dust collection box body 1, and the output end of the fan 5 is connected to the dust suction pipe 3, which is used to suck the dust and impurities inside the ore screening machine into the dust collection box body 1. Considering that dust enters the dust collector body 1 and passes through three dust collector plates 4 in sequence, since the dust particles vary in size, they will first pass through the top dust collector plate 4 together. If larger dust particles cannot pass through the top dust collector plate 4, they will remain on it. Meanwhile, smaller dust particles will have difficulty passing through the top dust collector plate 4, affecting the subsequent dust filtration. This dust may accumulate on the dust collector plates 4 inside the dust collector. By maintaining the three dust collector plates 4 at an inclined angle and installing vibration mechanisms on both sides of the dust collector plates 4, the three dust collector plates 4 vibrate slightly during dust filtration. Even if larger dust particles cannot pass through the top dust collector plate 4, the vibration will cause them to briefly leave the surface of the dust collector plate 4 and roll towards one end of the dust collector plate 4. The smaller dust particles above will then pass through the dust collector plates 4 in sequence. These larger dust particles... The material will also be transferred to the discharge window 104 according to the tilt angle of the dust removal plate 4, without clogging the dust removal plate 4. The vibration mechanism is set inside the dust removal box body 1 and is used to vibrate the three dust removal plates 4 up and down. The vibration mechanism includes: fixed plate one 101, fixed plate two 102, vibration motor 103 and elastic elements. One end of fixed plate one 101 is fixedly connected to one end of the three dust removal plates 4, and fixed plate two 102 is fixedly connected to the other end of the three dust removal plates 4. Two discharge windows 104 are opened on fixed plate two 102. Vibration motor 103 is installed at the other end of fixed plate one 101. Two elastic elements are fixedly connected to the bottom of fixed plate one 101 and fixed plate two 102. The bottom end of the elastic elements is fixedly connected to the bottom of the inside of the dust removal box body 1. When the vibration motor 103 works, it causes fixed plate one 101 and fixed plate two 102 to vibrate slightly on multiple elastic elements, so that multiple dust removal plates 4 also vibrate. It should be noted that the vibration motor 103 is fixed to one side of the fixed plate 101. The vibration motor 103 drives the fixed plate 101, the three dust removal plates 4, the three slag scraping components and the fixed plate 2 102 to vibrate together, rather than vibrating the entire dust collection box. Therefore, elastic elements are fixedly connected to the lower ends of both the fixed plate 101 and the fixed plate 2 102. The elastic elements include: support plate 105 and spring 106. There are two support plates 105 symmetrically arranged and fixedly connected to the fixed plate 2 102 and the inner bottom wall of the dust collection box body 1, respectively. The two sides of the spring 106 are fixedly connected to the two support plates 105, respectively. It should also be noted that, in this embodiment, when the vibration motor 103 is working, the vibration of the first fixed plate 101 drives the dust removal plate 4, the scraper assembly and the second fixed plate 102 to vibrate together. The vibration motor 103 does not produce a large vibration amplitude. During this process, the dust will briefly leave the surface of the dust removal plate 4 and then return to the dust removal plate 4. This vibration amplitude will not cause the dust to escape in the dust removal box. The upper ends of the first fixed plate 101 and the second fixed plate 102 will not collide with the suction pipe 3 during the vibration. The first fixed plate 101 is slidably connected to the inner wall of the dust removal box to prevent small dust particles from escaping everywhere. The side wall of the dust removal box that contacts the two discharge windows 104 is also provided with an opening 107 that is adapted to the discharge window 104 to facilitate the transfer of dust out of the dust removal box. Considering that the fan 5 transfers dust to the dust collection box, the dust may contain some air, and some small dust particles are easily dispersed after entering the dust collection box. This may cause dust to float above the dust collection plate 4. The atomizing component atomizes these floating dust particles, causing them to settle onto the dust collection plate 4 for filtration. This also facilitates subsequent cleaning of the dust collection plate 4. The atomizing component is located above the dust collection plate 4 to atomize the dust. The atomizing component includes a water collection tank 201. The system includes a water outlet pipe 202, a diversion plate 203, and multiple nozzles 204. The water collection tank 201 is fixedly connected to the top of the dust collector. One end of the water outlet pipe 202 is connected to the bottom of the water collection tank 201. The upper side of the diversion plate 203 is connected to the other end of the water outlet pipe 202. Multiple nozzles 204 are hinged to the lower side of the diversion plate 203. The water source in the water collection tank 201 is concentrated in the diversion plate 203 through the water outlet pipe 202, and finally sprayed by multiple nozzles 204 to spray the water source onto the dispersed dust. Considering that some dust particles may remain on the three dust collector plates 4 after the dust removal work is completed, these particles may be trapped in the filter holes of the dust collector plates 4, or they may be atomized and adsorbed onto the dust collector plates 4, making them difficult to remove even by vibration, a scraping assembly is installed on each dust collector plate 4. This assembly automatically collects and removes dust particles from the dust collector plates 4 after the dust removal work is completed. Three scraping assemblies are installed on the three dust collector plates 4 respectively, and are used to remove dust and debris from the three dust collector plates 4 to one side of the dust collector plates 4. Each scraping assembly includes four limiting blocks 301, two electric guide rods 302, two electric sliding sleeves 303, a scraper 304, and... The cleaning brush 305 has two limiting blocks 301 fixedly connected to one end of the first fixing plate 101 and two limiting blocks 301 fixedly connected to one end of the second fixing plate 102. The two ends of the electric guide rod 302 are fixedly connected to the two limiting blocks 301 respectively. The electric sliding sleeve 303 is sleeved on the electric guide rod 302. The two ends of the scraper 304 are fixedly connected to the two electric sliding sleeves 303 respectively. The cleaning brush 305 is fixedly connected to the bottom end of the scraper 304. When the electric sliding sleeve 303 is activated, it drives the scraper 304 and the cleaning brush 305 to move along the electric sliding rod. During this process, the cleaning brush 305 cleans the dust removal plate 4 and removes the dust adsorbed on the dust removal plate 4. After the dust removal process is completed, dust that has not passed through the first two dust collector plates 4 will roll off during vibration due to the tilt of the dust collector plates 4 and concentrate at the two discharge windows 104. Smaller dust particles will fall into the collection tank 401 after being filtered by the three dust collector plates 4. There may still be some dust adsorbed or retained on the dust collector plates 4. The dust adsorbed or retained on the dust collector plates 4 will also be removed by the scraping assembly into the two discharge windows 104 and the collection tank 401. However, this dust accumulation at the two discharge windows 104 needs to be cleaned in time. By setting the collection box 402 and the collection tank 4 at the bottom of the two discharge windows 104 and the dust collector body 1, a solution is found. 01. Dust is collected and removed. The collection trough 401 is trapezoidal. The collection assembly is used to collect dust and debris on the three dust removal plates 4. The collection assembly includes a collection trough 401, a collection box 402, and a baffle 403. The collection trough 401 is slidably connected to the dust removal box. The collection trough 401 is located at the bottom of the dust removal box. A handle 404 is fixedly connected to the side wall of the collection trough 401. The collection box 402 is fixedly connected to one side wall of the dust removal box. A movable door 405 is opened on the collection box 402. A sliding groove is opened on the collection box 402. The baffle 403 is slidably connected to the collection box 402. A handle 406 is fixedly connected to the side wall of the baffle 403.
[0017] It should also be noted that the dust collector body 1 also has an opening 107 of the same size as the discharge window 104, used to remove dust from the two discharge ports. Considering that if the collection box 402 is always connected to the two discharge windows 104, when the dust first enters the dust collector and is vibrated by the uppermost dust collector plate 4, this dust may vibrate and roll to the discharge window 104. Since the discharge window 104 is connected to the collection box 402, this dust may be directly removed into the collection box 402. However, this dust is not all large-particle dust; it may contain dust of different sizes. These small dust particles are not directly removed into the collection box 402 without passing through the three dust collector plates 4 in sequence. 2. This may affect the effect of graded dust removal. By sliding a baffle 403 on the collection box 402, when dust removal is performed, the baffle 403 blocks the two discharge windows 104 from communicating with the collection box 402, so that the dust temporarily accumulates in the two discharge windows 104. After the dust removal is completed, the baffle 403 is pulled open, and the dust is removed into the collection box 402 by the scraping assembly. Considering that the vibration force generated by the vibration motor 103 when it is working causes the dust to vibrate slightly up and down on the dust removal plate 4, and the vibration fluctuation is small, this avoids the dust from escaping into the dust removal box due to the large vibration amplitude. The fixed plate 102 is slidably connected to the inner wall of the dust removal box body 1. During the vibration process, gaps are avoided as much as possible to prevent the dust from escaping everywhere.
[0018] Working Principle: A dust removal device for ore screening is placed at a suitable working location. The dust collection box is connected to the ore screening machine via a dust suction pipe 3. A fan 5 transfers the escaping dust into the dust collection box for grading and dust removal, preventing dust from escaping and polluting the working environment due to ore vibration screening. One end of the dust collection pipe is positioned directly above the dust collection plate 4, and this end is L-shaped, allowing the dust to be graded and removed after entering the dust collection box. The vibration motor 103 is activated, causing the dust particles to vibrate slightly up and down on the dust collection plate 4, preventing blockage of the plate and ensuring proper dust removal for subsequent incoming dust. When the vibration motor 103 is turned on, the atomizing component atomizes some dust floating above the dust collector plate 4 and causes it to settle on the dust collector plate 4. During vibration, the dust passes through the three dust collector plates 4 in sequence. Due to the certain inclination angle of the three dust collector plates 4, the dust rolls to one side of the dust collector plate 4. The dust on the first two dust collector plates 4 rolls to the two discharge windows 104. The dust that passes through the three dust collector plates 4 falls directly into the collection tank 401 for subsequent cleaning. Since one end of the baffle 403 is embedded in the inner wall of the collection box 402 and is connected to the collection box 402, the dust is cleaned up and cleaned up. 02 Sliding connection, the dust accumulated at the two discharge windows 104 is blocked by the baffle 403 and cannot directly roll into the collection box 402. After the dust removal work is completed, the fan 5, vibration motor 103 and atomizing component are turned off. At this time, most of the dust is concentrated in the two discharge windows 104 and the collection tank 401. Some dust settles on the dust removal plate 4 through atomization and is adsorbed on the dust removal plate 4. The electric sliding sleeve 303 is started, which drives the scraper 304 and cleaning brush 305 to move along the electric sliding rod. During this process, the cleaning brush 305 cleans the dust removal plate 4 and... The dust adsorbed on the dust collector plate 4 is cleaned, and then the baffle 403 is pulled out to connect the collection box 402 with the two discharge windows 104. This allows the dust adsorbed on the dust collector plate 4, along with the dust accumulated at the two discharge windows 104, to be removed into the collection box 402. After scraping the slag, the baffle 403 is returned to its original position, and then the movable door 405 is opened to remove the dust in the collection box 402. The collection trough 401 is pulled out by the handle 404 to remove the dust in the collection trough 401. This completes the classification and dust removal of the dust, minimizing the risk of dust escaping during ore vibration screening.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
