Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dry dust removal device for sand ore beneficiation. Background Technology

[0002] Extracting the required minerals from placer deposits requires rolling screening, which generates a large amount of dust, thus impacting the working environment.

[0003] In related technologies, dust removal is carried out simultaneously during the rolling screening process. The dust removal process generally uses gas adsorption dust removal through filtration equipment such as filter screens. In a space, the flow of gas traps dust as it passes through the filter screens, thus achieving the purpose of dust removal. However, this makes it easy for dust to adhere to the walls of the space where the filter screen is located. Over time, this can affect the dust removal effect and the judgment of the dust removal effect. At the same time, with long-term dust removal and filtration, dust can easily accumulate on the filter screen, affecting the filtration quality and efficiency of the filter screens and other filtration equipment.

[0013] In one embodiment, the filtration unit further includes a filter element and a vibrating element. The filter element is connected to and separates the dust removal chamber. The vibrating element is embedded in the wall of the dust removal chamber and is in contact with the filter element.

[0014] The main body has multiple air extraction sections on its side, and one of the air extraction sections is located on the side of the dust removal chamber away from the dry separation section and is connected to the dust removal chamber.

[0032] Extracting the required minerals from placer deposits requires rolling screening, which generates a large amount of dust, thus impacting the working environment.

[0033] In related technologies, dust removal is carried out simultaneously during the rolling screening process. The dust removal process generally uses gas adsorption dust removal through filtration equipment such as filter screens. In a space, the flow of gas traps dust as it passes through the filter screens, thus achieving the purpose of dust removal. However, this makes it easy for dust to adhere to the walls of the space where the filter screen is located. Over time, this can affect the dust removal effect and the judgment of the dust removal effect. At the same time, with long-term dust removal and filtration, dust can easily accumulate on the filter screen, affecting the filtration quality and efficiency of the filter screens and other filtration equipment.

[0034] This utility model proposes a dust removal device for dry sand ore beneficiation.

[0035] Please see Figure 1 and Figure 2In one embodiment of this utility model, the dry sand ore beneficiation dust removal device includes:

[0036] Dry separation component 10, the dry separation component 10 includes a dry separation section 12, the dry separation section 12 is provided with a feed inlet 11;

[0037] Dust removal assembly 20 includes a main body, a plurality of dust removal chambers 27 are spaced apart inside the main body, a filter section 23 is provided in each of the plurality of dust removal chambers 27, and a pipe assembly 21 is provided on the main body to connect the plurality of dust removal chambers, the pipe assembly 21 connecting the dry separation section 12 and the feed inlet 11;

[0038] The dust removal chamber 27 is provided with a sealing structure 24 to close the dust removal chamber 27. The sealing structure 24 includes a partition 242 and a limiting part 241. The partition 242 is rotatably connected to the dust removal chamber 27. The limiting part 241 is located on the side of the partition 242 away from the filter part 23 and abuts against the partition 242. The side of the partition 242 is in contact with the chamber wall of the dust removal chamber 27.

[0039] like Figure 1 As shown, a support bracket 13 is connected to the dry separation section 12 to support the dry separation section 12.

[0040] It is understandable that in order to perform rolling screening of a large amount of sand ore simultaneously, the dry screening section 12 is set in a cylindrical shape, and the support 13 is set to support the cylindrical dry screening section 12, so as to ensure the stability of the dry screening section 12 during the rolling screening process, thereby ensuring the high efficiency of sand ore screening.

[0041] It should be noted that, in order to realize the rolling screening of sand ore by the dry separation section 12, the dry separation section 12 is rotatably connected to the support 13, and a screening chamber for accommodating sand ore is provided in the dry separation section 12.

[0042] It is understood that, in order to transport sand ore into the screening chamber, the feed inlet 11 is provided on the dry separation section 12, and the feed inlet 11 is connected to the screening chamber.

[0043] In order to facilitate the simultaneous treatment of dust during the rolling screening process of the dry separation section 12, the main body is set on one side of the support 13, and the dry separation section 12 is connected to the main body through the pipe assembly 21. The dust is filtered by the filter section 23 set in the main body.

[0044] It should be noted that, in order to facilitate the processing of the filter section 23 which has been filtering dust for a long time without affecting the normal filtration efficiency, a plurality of dust removal chambers 27 are provided in the main body, and each dust removal chamber 27 is provided with the closed structure 24.

[0045] It is understandable that when the filter section 23 in one of the dust removal chambers 27 needs to be cleaned, the dust removal chamber 27 is closed by controlling the sealing structure 24 to facilitate the cleaning of the filter section 23. At this time, the remaining dust removal chambers 27 can carry out dust removal operations normally, thereby ensuring the normal and orderly progress of dust removal.

[0046] like Figure 2 As shown, the partition 242 is rotatably connected to the dust removal chamber 27, and the side of the partition 242 is in contact with the wall of the dust removal chamber 27.

[0047] It is understood that when the filter section 23 in the dust removal chamber 27 performs dust removal and filtration, the partition 242 rotates and contacts the filter section 23. At this time, the dust removal chamber 27 is no longer closed by the partition 242. At this time, the airflow carrying dust enters the dust removal chamber 27 and is filtered and removed by the filter section 23.

[0048] Understandably, when it is necessary to clean the filter section 23 in the dust removal chamber 27 to ensure filtration quality, the partition 242 is rotated. At this time, the side of the partition 242 scrapes off the dust adhering to the side wall of the dust removal chamber 27 as it rotates, thereby achieving cleaning of the dust removal chamber 27 and ensuring dust removal quality. At the same time, the rotated partition 242 closes the dust removal chamber 27, thereby facilitating the cleaning or replacement of the filter section 23 in the dust removal chamber 27.

[0049] It should be noted that, in order to improve the scraping quality of the dust removal chamber 27 wall by the partition 242, a scraping section is provided on the side of the partition 242.

[0050] In one embodiment, the scraping part may be a brush or a friction part.

[0051] like Figure 2 As shown, the limiting part 241 is provided on one side of the partition 242. When the partition 242 rotates, it impacts the limiting part 241, thereby limiting the rotation angle of the partition 242 and shaking off the dust adhering to the surface of the partition 242 through vibration, thus cleaning the partition 242 and preventing large dust particles from affecting the filtration effect of the filter part 23.

[0052] It should be noted that multiple limiting parts 241 are provided, and the multiple limiting parts 241 are arranged at intervals along the outer edge of the opening of the dust removal chamber 27, so as to improve the vibration effect of the partition 242 hitting the limiting parts 241 and thus improve the dust shaking effect.

[0053] Furthermore, in order to repeatedly impact the limiting part 241 during the process of shaking off the dust on the partition 242, a torsion spring is provided at the rotation center of the partition 242, and the multiple impacts of the partition 242 are achieved by relying on the elastic force of the torsion spring.

[0054] The technical solution of this utility model uses the pipe assembly 21 to transmit the airflow carrying dust from the dry separation section 12 and the feed inlet 11 to multiple dust removal chambers 27, where it is filtered by multiple filter sections 23 for dust removal. When it is necessary to clean a certain dust removal chamber 27 and the filter section 23 therein, the partition 242 is rotated. The rotation of the partition 242 scrapes off the dust adhering to the wall of the dust removal chamber 27, and the partition 242 rotates to close the dust removal chamber 27, making it easy to replace or clean the filter section 23. In this way, the cleaning of a certain dust removal chamber 27 and the filter section 23 can be achieved without affecting the normal dust removal of the dry separation section 12 and the feed inlet 11. After the dust removal chamber 27 and the filter section 23 are cleaned, the partition 242 is rotated again to facilitate the dust removal operation again, thereby improving the dust removal quality and efficiency.

[0055] In one embodiment, the main body is provided with a driving part 22, which is connected to the partition 242 to make the partition 242 rotate.

[0056] In order to enable the partition 242 to rotate, the drive unit 22 is provided inside the main body.

[0057] It is understood that the drive unit 22 outputs power to drive the partition 242 to rotate, thereby controlling the rotation of the partition 242 within the dust removal chamber 27.

[0058] In one embodiment, the main body is provided with a drive cavity 26, and the drive part 22 is disposed in the drive cavity 26. The partition 242 is provided with a transmission part 243 on the side opposite to the limiting part 241. The transmission part 243 is partially inserted into the drive cavity 26 and connected to the drive part 22.

[0059] like Figure 2 As shown, the drive cavity 26 is provided in the main body to accommodate the drive unit 22, and the transmission unit 243 is partially inserted into the drive cavity 26 and connected to the drive unit 22.

[0060] It is understood that the drive unit 22 outputs power to drive the transmission unit 243 to rotate, which in turn drives the partition 242 to rotate, thereby achieving rotation control of the partition.

[0061] In one embodiment, the transmission part 243 is arranged in an arc shape, and the rotation center of the transmission part 243 coincides with the rotation center of the partition 242.

[0062] like Figure 2 and Figure 3 As shown, in order to make the rotation of the transmission part 243 coincide with the rotation of the partition 242, the rotation center of the transmission part 243 coincides with the rotation center of the partition 242.

[0063] It is understood that when the drive unit 22 drives the transmission unit 243 to rotate, the partition plate 242 rotates around the same rotation center to ensure the stability of the rotation.

[0064] It is understood that the transmission part 243 is arranged in an arc shape so that when the drive part 22 controls the transmission part 243 to rotate, it can drive the transmission part 243 to rotate synchronously with the partition plate 242, thus ensuring the stability of the rotation.

[0065] In one embodiment, the drive unit 22 includes a drive member 221 and a half-wheel portion 222. The drive member 221 is connected to the cavity wall of the drive cavity 26, and the output end of the drive member 221 is connected to the half-wheel portion 222. The half-wheel portion 222 abuts against the side of the transmission unit 243.

[0066] like Figure 2 As shown, the output end of the drive unit 221 is connected to the half-wheel part 222.

[0067] It is understood that when the drive unit 221 outputs power, it drives the half-wheel part 222 to rotate, which in turn drives the transmission part 243 to rotate.

[0068] It should be noted that the half-wheel portion 222 is in contact with the arc-shaped surface of the transmission portion 243.

[0069] Understandably, when the partition 242 needs to be rotated to open the dust removal chamber 27, the drive member 221 drives the half-wheel portion 222 to rotate, thereby driving the partition 242 to rotate until the partition 242 abuts against the filter portion 23; when the dust removal chamber 27 needs to be closed, the drive member 221 drives the half-wheel portion 222 to rotate, thereby driving the partition 242 to rotate and move away from the filter portion 23. When the half-wheel portion 222 disengages from the transmission portion 243, the partition 242 rotates under its own weight and impacts the limiting portion 241. This allows the dust adhering to the surface of the partition 242 to be shaken off. When the partition 242 needs to be rotated again and the dust removal chamber 27 needs to be opened, the half-wheel part 222 rotates under the action of the driving member 221. At this time, the partition 242 does not rotate with the rotation of the half-wheel part 222 under the restriction of the limiting part 241. Until the lower left edge of the half-wheel part 222 contacts the transmission part 243, the driving member 221 outputs power in the opposite direction, causing the half-wheel part 222 to rotate in the opposite direction, thereby driving the partition 242 to rotate and opening the dust removal chamber 27.

[0070] It should be noted that the transmission part 243 abuts against the half-wheel part 222.

[0071] It should be noted that the driving component 221 includes a motor and a motor shaft. The motor is fixed inside the driving cavity 26, and the motor shaft is poweredly connected to the motor. The motor shaft is connected to the half-wheel part 222.

[0072] In one embodiment, the filter section 23 further includes a filter element 231 and a vibrating element 232. The filter element 231 is connected to the dust removal chamber 27 and separates the dust removal chamber 27. The vibrating element 232 is embedded in the wall of the dust removal chamber 27 and is in contact with the filter element 231.

[0073] The main body has multiple air extraction sections 25 on its side. One air extraction section 25 is located on the side of one of the dust removal chambers 27 away from the dry separation section 12 and is connected to the dust removal chamber 27.

[0074] It is understood that a vibrating element 232 is connected between the filter element 231 and the main body. When it is necessary to clean the dust on the surface of the filter element 231, the vibrating element 232 works to drive the filter element 231 to vibrate, thereby shaking off the dust on the surface of the filter element 231 and cleaning the filter element 231.

[0075] It should be noted that the filter element 231 is a filter screen.

[0076] It is understood that the air extraction section 25 is provided on the side of the main body away from the dry separation section 12. When the air extraction section 25 is working, it draws in air, thereby drawing the dust through the pipe assembly 21 into the dust removal chamber 27, where it is filtered and cleaned by the filter element 231.

[0077] In one embodiment, the main body is provided with a collection chamber 28, which is connected to a plurality of dust removal chambers 27, and the pipe assembly 21 is connected to the collection chamber 28 to collect gas in a centralized manner.

[0078] In order to transfer the dust-laden gas from the pipeline group 21 to each of the dust removal chambers 27, a collection chamber 28 is provided in the main body. Through the transfer in the collection chamber 28, each of the dust removal chambers 27 can achieve stable dust removal and ensure the quality of dust removal.

[0079] In one embodiment, the pipeline assembly 21 includes a first vent 211 and a second vent 212. The first vent 211 connects the feed inlet 11 and the collecting chamber 28 to collect dust at the feed inlet 11. The second vent 212 connects the dry separation section 12 and the collecting chamber 28 to collect dust at the dry separation section 12.

[0080] It should be noted that when sand is fed into the feed inlet 11, the dumped sand will generate dust, and the dust will spread into the working space through the feed inlet 11, affecting the working environment.

[0081] It is understood that the first ventilation channel 211 is connected to the feed inlet 11, thereby gathering the dust in the feed inlet 11 toward the collection chamber 28.

[0082] It is understood that the second ventilation duct 212 is connected to the dry separation section 12, thereby transferring the dust in the dry separation section 12 to the collection chamber 28.

[0083] In one embodiment, the feed inlet 11 includes a feed pipe 111 and a surrounding portion 113. The feed pipe 111 is connected to the dry separation unit 12. The surrounding portion 113 surrounds the outer side of one end of the feed pipe 111. The surrounding portion 113 and the feed pipe 111 together form a collection space. The first vent 211 communicates with the collection space. A plurality of vent holes 112 are provided on the side of the feed pipe 111 opposite to the surrounding portion 113.

[0084] In order to adsorb the dust in the feed pipe 111, a collection space is formed around the inlet of the feed pipe 111, and the first vent 211 is connected to the collection space.

[0085] It is understandable that when the exhaust unit 25 is working to extract air, dust is carried by the airflow through the first ventilation channel 211 into the collection chamber 28, and then into the dust removal chamber 27 for dust removal.

[0086] In one embodiment, the main body is provided with a receiving portion 29 for collecting the dust deposited in the dust removal chamber 27.

[0087] In order to collect the dust shaken off in the collection chamber 28 and the dust removal chamber 27, a receiving space 294 is provided on the main body, and a first connection port is provided between the receiving space 294 and the collection chamber 28, and a second connection port is provided between the receiving space 294 and the dust removal chamber 27. A cylindrical barrel 292 is provided in the receiving space 294, and a receiving cavity is provided in the cylindrical barrel 292. Two openings 293 are provided in the cylindrical barrel 292, and both openings 293 are connected to the receiving cavity.

[0088] When it is necessary to cut off the connection between the accommodating space 294 and the collecting chamber 28 and the dust removal chamber 27, the cylindrical barrel 292 is rotated, and the first connection port and the second connection port are blocked by the outer surface of the cylindrical barrel 292.

[0089] When it is necessary to collect dust in the collection chamber 28 and the dust removal chamber 27, rotate the cylindrical barrel 292 so that the opening 293 is connected to the first connection port 291 and / or the opening 293 is connected to the second connection port 295. At this time, the dust will automatically slide into the cylindrical barrel 292, and the collection will be completed.

[0090] It should be noted that the cylindrical bucket 292 can be retrieved or stored by pulling it out.

[0091] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
