Description

Technical Field

[0001] This invention belongs to the field of mineral processing and dust removal, specifically, it relates to a dust removal device for mineral processing. Background Technology

[0002] Mineral beneficiation is the process of separating useful minerals from gangue minerals based on the characteristics of different minerals in ore, removing or reducing harmful impurities to obtain the raw materials needed for industry. Mineral beneficiation generates a large amount of dust and other floating matter, which can affect the surrounding environment. Dust removal equipment is needed to remove dust and other floating matter.

[0003] Existing methods mainly involve dust removal by spraying water mist. However, this method increases the weight of the ore, leading to increased pressure on the conveyor belt and making it prone to damage. Furthermore, the conveyor belt is easily contaminated with a large amount of water-laden mud and sand, which is detrimental to the long-term use of the equipment. As for dust collection and filtration, the suction range of a single device is limited and it is difficult to adjust according to the usage scenario. Using multiple devices is costly, and each device usually has an independent filter structure, making subsequent cleaning and replacement operations cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dust removal device for mineral processing.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A dust removal device for mineral processing includes multiple arc-shaped frames and multiple dust collection components. The sides of the arc-shaped frames are provided with several slots that extend horizontally through the arc-shaped frames. Arc-shaped channels are provided inside the arc-shaped frames, with the slots located on the sides of the arc-shaped channels. Dust-guiding hoses connected to the arc-shaped channels are provided on both sides of the lower part of the arc-shaped frames. Insertion holes corresponding to the slots are provided on the inner wall of the arc-shaped frames and are connected to the arc-shaped channels. Elastic telescopic sealing parts corresponding to the insertion holes are provided on the outer ring wall side of the arc-shaped channels.

[0007] The vacuuming assembly includes a vacuum box, with a lower clamping plate connected to the upper part of the vacuum box. A top cylinder adapted to the insertion hole is provided on the upper side of the lower clamping plate, and multiple dust outlet holes are provided on the side of the top cylinder. A conical groove is provided vertically on the lower clamping plate, which is connected to the top cylinder and the vacuum box. The conical groove passes through the lower clamping plate. A first side stop is installed on one side of the lower clamping plate, and a screw is rotatably fitted on the first side stop. An upper clamping plate is threaded around the screw, and a knob is provided at the upper end of the screw.

[0008] Optionally, the lower part of the arc-shaped frame is provided with two support frames, each including a top plate and a bottom plate. The top plate is located above the bottom plate, and a support plate and two reinforcing plates are welded between the top plate and the bottom plate. The support plate is welded between the two reinforcing plates. The bottom plate has multiple vertical mounting holes that penetrate through the bottom plate. The reinforcing plates improve the bending resistance and load-bearing capacity of the support plate. The mounting holes and the bottom plate work together to facilitate the installation and fixing of the dust removal equipment in the designated position.

[0009] Optionally, a connecting plate corresponding to the top plate is installed on the lower side of the arc-shaped frame. The connecting plate is located above the top plate and has two first connecting holes vertically through it. The top plate has two second connecting holes vertically through it. Bolts are installed on the connecting plate, which pass through the first and second connecting holes in sequence. Nuts are threaded around the bolts and are located below the top plate. The arc-shaped frame and the support plate are both located between two bolts. The bolts and nuts are located between two reinforcing plates. The bolts and nuts facilitate the connection and fixation of the top plate and the connecting plate.

[0010] Optionally, the elastic telescopic sealing component includes a sealing cap and a limiting ring located around the sealing cap. The limiting ring is installed on the outer ring wall side of the arc-shaped through groove. The upper end of the sealing cap is provided with a receiving groove. A spring is provided between the lower end of the inner wall of the receiving groove and the outer ring wall of the arc-shaped through groove. The inner ring wall side of the arc-shaped through groove is provided with a sealing hole located around the insertion hole. The sealing hole is connected to the insertion hole. A sealing ring is installed at the lower end of the inner wall of the sealing hole. The sealing ring is located around the insertion hole. The diameter of the sealing cap is greater than the diameter of the insertion hole and less than or equal to the diameter of the sealing hole. The sealing hole restricts the displacement distance of the sealing cap, thereby reducing the probability of the sealing cap completely disengaging from the limiting ring. The sealing ring improves the sealing effect of the sealing cap on the insertion hole.

[0011] Optionally, the upper side of the first side stop is provided with a T-shaped groove, the lower part of the screw is rotatably engaged in the T-shaped groove, and the lower end of the screw is provided with a rotating block that is rotatably engaged in the T-shaped groove. Through the cooperation of the T-shaped groove and the rotating block, the probability of the screw disengaging from the first side stop is reduced.

[0012] Optionally, a second side stop is provided on the lower side of the upper clamping plate, and the arc-shaped frame is located between the first side stop and the second side stop. The second side stop reduces the probability of the upper clamping plate sliding or shaking after installation.

[0013] Optionally, a cylinder is provided on the side of the first side block away from the lower clamping plate, and a guide rod is provided on the side of the upper clamping plate. The cylinder is sleeved around the guide rod. By cooperating with the guide rod, the probability of rotational misalignment between the lower clamping plate and the upper clamping plate is reduced.

[0014] Optionally, the dust collection box includes a connecting cylinder installed on the lower side of the lower clamping plate. The connecting cylinder is located on the periphery of the conical groove. A dust guide hopper is connected to the lower end of the connecting cylinder, and a suction cylinder is connected to the lower end of the dust guide hopper. A dust inlet hopper is connected to the lower end of the suction cylinder, and a protective shell is connected to its side. A limit frame is installed inside the suction cylinder, and a rotating shaft is rotatably fitted on the limit frame. A fan blade and a first synchronous pulley are respectively provided at the upper and lower ends of the rotating shaft. The first synchronous pulley is located above the fan blade. A motor is installed inside the protective shell, and a second synchronous pulley is fixedly connected to the output shaft of the motor. A synchronous belt is sleeved around the periphery of the first and second synchronous pulleys. The dust guide hopper and the conical groove facilitate the passage of dust and reduce the probability of dust remaining in the dust collection box or the lower clamping plate.

[0015] Optionally, the limiting frame includes a bearing mounted on the circumference of the rotating shaft, a ring plate mounted on the circumference of the bearing, and three side support rods mounted on the side of the ring plate. The side support rods are mounted on the inner wall side of the suction cylinder. The bearing reduces the friction between the rotating shaft and the ring plate when the shaft rotates.

[0016] Optionally, the suction cylinder has a slot on its side that corresponds to the timing belt. The slot is connected to the suction cylinder and the protective shell. The timing belt passes through the slot laterally. A dustproof sponge is installed between the upper and lower sides of the inner wall of the slot. The timing belt is located around the dustproof sponge. The dustproof sponge reduces the probability of dust entering the protective shell from the slot.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] The curved frame and dust collection components work together to facilitate the installation of an appropriate number of curved frames according to usage needs, and to install an appropriate number of dust collection components on the curved frames according to the size of the dust. The slot and the first side stop facilitate the positioning and installation of the dust collection components, making it easy to align the top cylinder with the insertion hole. The insertion hole is sealed by an elastic telescopic sealing component to reduce air leakage in unused insertion holes. The upper clamping plate is threaded around the screw, making it easy to rotate the knob to clamp and fix the lower clamping plate on the curved frame. The top cylinder squeezes the elastic telescopic sealing component to shrink, placing the dust outlet in the curved through groove, realizing quick connection between the dust collection box and the curved through groove. Since the dust collection box only needs to have a dust collection function, the production cost of the dust collection components is reduced. At the same time, with the dust guide hose, the dust removal equipment can be connected to an external filter device, which facilitates the subsequent cleaning and replacement of filter media.

[0028] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0029] The invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-4As shown, this embodiment provides a dust removal device for mineral processing, including multiple arc-shaped frames 1 and multiple dust collection components 6. The side of the arc-shaped frame 1 is provided with several slots 101, which transversely penetrate the arc-shaped frame 1. The arc-shaped frame 1 is provided with an arc-shaped through groove 102, and the slots 101 are located on the side of the arc-shaped through groove 102. Both sides of the lower part of the arc-shaped frame 1 are connected with dust guiding hoses 105 that communicate with the arc-shaped through groove 102. The inner wall of the arc-shaped frame 1 is provided with insertion holes 103 corresponding to the slots 101, which communicate with the arc-shaped through groove 102. The outer ring wall of the arc-shaped through groove 1 is provided with elastic telescopic sealing parts corresponding to the insertion holes 103.

[0031] The vacuuming assembly 6 includes a vacuum box, with a lower clamping plate 7 connected to the upper part of the vacuum box. The upper side of the lower clamping plate 7 is provided with a top cylinder 702 that is adapted to the insertion hole 103. The upper end of the top cylinder 702 is a sealed structure. The side of the top cylinder 702 is provided with multiple dust outlet holes 703. The lower clamping plate 7 is vertically provided with a conical groove 701 that communicates with the top cylinder 702 and the vacuum box. The conical groove 701 passes through the lower clamping plate 7. A first side stop 704 is installed on one side of the lower clamping plate 7. A screw 9 is rotatably fitted on the first side stop 704. An upper clamping plate 8 is threaded around the screw 9. A knob 902 is provided at the upper end of the screw 9.

[0032] One application of this embodiment is as follows: Before use, a corresponding number of arc-shaped frames 1 are set up according to the required dust removal space distance. Then, according to the size of the dust, a corresponding number of dust collection components 6 are installed on each arc-shaped frame 1. Then, multiple dust guide hoses 105 are connected to a filter device. The process of installing the dust collection components 6 is as follows: the upper clamping plate 8 is clamped in the corresponding slot 101, and the dust collection box is supported and stabilized. Then, the knob 902 is rotated to drive the screw 9 to rotate. The rotation of the screw 9 brings the upper clamping plate 8 and the lower clamping plate 7 closer together, so that the upper clamping plate 8 and the lower clamping plate 7 cooperate to clamp the arc-shaped frame 1. During the clamping process, the first side stop 704 needs to abut against the arc-shaped frame 1. The top cylinder 702 is aligned with the insertion hole 103 by the side clamping plate 8 and the lower clamping plate 7. When the upper clamping plate 8 and the lower clamping plate 7 are clamped together, the top cylinder 702 is inserted into the insertion hole 103 and the elastic telescopic sealing member is squeezed and contracted, so that the elastic telescopic sealing member cancels the sealing of the insertion hole 103. At this time, the dust outlet 703 is placed inside the arc-shaped through groove 102. During use, the dust collection box works to draw in air, and the dust generated by mineral processing is drawn into the dust collection box along with the air. Then the air and dust pass through the cone groove 701, the top cylinder 702, the dust outlet 703, the arc-shaped through groove 1 and the dust guide hose 105 in sequence and enter the filter equipment. The dust in the air is filtered by the filter equipment in the prior art.

[0033] In this embodiment, the lower part of the arc-shaped frame 1 is provided with two support frames, each including a top plate 402 and a bottom plate 403. The top plate 402 is located above the bottom plate 403. A support plate 4 and two reinforcing plates 401 are welded between the top plate 402 and the bottom plate 403. The support plate 4 is welded between the two reinforcing plates 401. The bottom plate 403 is provided with multiple vertical mounting holes that penetrate the bottom plate 403. The reinforcing plates 401 improve the bending resistance and load-bearing capacity of the support plate 4, while supporting the arc-shaped frame 1 and reducing the impact of the dust removal equipment on the accessibility of the surrounding environment. The mounting holes and the bottom plate 403 cooperate to facilitate the installation and fixing of the dust removal equipment in the designated position.

[0034] In this embodiment, the lower side of the arc-shaped frame 1 is equipped with a connecting plate 106 corresponding to the top plate 402. The connecting plate 106 is located above the top plate 402. The connecting plate 106 has two first connecting holes vertically, which penetrate the connecting plate 106. The top plate 402 has two second connecting holes vertically, which penetrate the top plate 402. The connecting plate 106 is provided with bolts 5 that pass through the first connecting holes and the second connecting holes in sequence. The bolts 5 are threaded with nuts 501 on their periphery. The nuts 501 are located below the top plate 402. The arc-shaped frame 1 and the support plate 4 are both located between the two bolts 5. The bolts 5 and the nuts 501 are located between the two reinforcing plates 401. The bolts 5 and the nuts 501 are used to facilitate the connection and fixation of the top plate 402 and the connecting plate 106, thereby facilitating the assembly and disassembly of the arc-shaped frame 1 and the support frame. The support frame of appropriate height can be replaced as needed.

[0035] The elastic telescopic sealing component of this embodiment includes a sealing cap 201 and a limiting ring 2 located around the sealing cap 201. The limiting ring 2 is installed on the outer ring wall side of the arc-shaped through groove 1. The upper end of the sealing cap 201 is provided with a receiving groove. A spring 202 is provided between the lower end of the inner wall of the receiving groove and the outer ring wall of the arc-shaped through groove 1. The inner ring wall side of the arc-shaped through groove 1 is provided with a sealing hole 104 located around the insertion hole 103. The sealing hole 104 is connected to the insertion hole 103. A sealing ring 3 is installed on the lower end of the inner wall of the sealing hole 104. The sealing ring 3 is located around the insertion hole 103. The diameter of the sealing cap 201 is larger than the diameter of the insertion hole 103 and smaller than or equal to the diameter of the sealing hole 104. When the vacuum cleaner assembly 6 is disassembled, the top cylinder 702 releases its pressure on the sealing cover 201. The spring 202 rebounds and pushes the sealing cover 201 downward along the limiting ring 2 until the sealing cover 201 is inserted into the sealing hole 104 and compresses the sealing ring 3. This achieves the sealing of the insertion hole 103 by the sealing cover 201. The limiting ring 2 restricts the displacement direction of the sealing cover 201, which facilitates the alignment of the sealing cover 201 with the sealing hole 104. The sealing hole 104 restricts the displacement distance of the sealing cover 201, thereby reducing the probability that the sealing cover 201 will completely detach from the limiting ring 2. The sealing ring 3 improves the sealing effect of the sealing cover 201 on the insertion hole 103.

[0036] In this embodiment, the upper side of the first side stop 704 is provided with a T-shaped groove, the lower part of the screw 9 is rotatably engaged in the T-shaped groove, and the lower end of the screw 9 is provided with a rotating block 901 rotatably engaged in the T-shaped groove. The displacement of the screw 9 is restricted by the T-shaped groove and the rotating block 901, while ensuring the free rotation of the screw 9 and reducing the probability of the screw 9 disengaging from the first side stop 704.

[0037] In this embodiment, the upper clamping plate 8 is provided with a second side stop 801 on the lower side. The arc frame 1 is located between the first side stop 704 and the second side stop 801. The second side stop 801 facilitates the further positioning and installation of the dust collection component 6, reducing the probability of the upper clamping plate 8 sliding or shaking after installation.

[0038] In this embodiment, the first side stop 704 is provided with a cylinder 705 on the side away from the lower clamping plate 7, and the upper clamping plate 8 is provided with a guide rod 802 on the side. The cylinder 705 is sleeved on the periphery of the guide rod 802. By cooperating with the guide rod 802, the probability of rotational misalignment between the lower clamping plate 7 and the upper clamping plate 8 is reduced, and the probability of the rotating screw 9 causing the upper clamping plate 8 or the first side stop 704 to rotate is reduced.

[0039] The dust collection box in this embodiment includes a connecting cylinder 10 installed on the lower side of the lower clamping plate 7. The connecting cylinder 10 is located on the periphery of the conical groove 701. A dust guide hopper 1001 is connected to the lower end of the connecting cylinder 10. A suction cylinder 1002 is connected to the lower end of the dust guide hopper 1001. A dust inlet hopper 1003 is connected to the lower end of the suction cylinder 1002, and a protective shell 1004 is connected to its side. A limit frame is provided inside the suction cylinder 1002. A rotating shaft 13 is rotatably fitted on the limit frame. A fan blade 1301 and a first synchronous pulley 1302 are respectively provided at the upper and lower ends of the rotating shaft 13. The first synchronous pulley 1302 is located above the fan blade 1301. A motor 14 is installed inside the protective shell 1004. The output shaft of the motor 14 is fixedly connected to... The second synchronous pulley 1401, the first synchronous pulley 1302, and the second synchronous pulley 1401 are fitted with a synchronous belt 15. The dust inlet 1003 increases the opening area of ​​the lower part of the suction cylinder 1002, thereby expanding the suction range of the dust collection box. The dust guide hopper 1001 and the conical groove 701 facilitate the passage of dust and reduce the probability of dust staying in the dust collection box or the lower clamping plate 7. In use, the motor 14 drives the second synchronous pulley 1401 to rotate. The second synchronous pulley 1401 drives the first synchronous pulley 1302 to rotate through the synchronous belt 15, and at the same time drives the rotating shaft 13 and the fan blade 1301 to rotate. The rotation of the fan blade 1301 generates suction at the dust inlet hopper 1003.

[0040] The limiting frame in this embodiment includes a bearing 12 installed around the rotating shaft 13. A ring plate 11 is installed around the bearing 12. Three side support rods 1101 are installed on the side of the ring plate 11. The side support rods 1101 are installed on the inner wall side of the suction cylinder 1002. The bearing 12 reduces the friction between the rotating shaft 13 and the ring plate 11 when the shaft rotates, thereby saving energy and ensuring the rotation speed of the fan blade 1301.

[0041] In this embodiment, the suction cylinder 1002 has a slot on its side that corresponds to the synchronous belt 15. The slot is connected to the suction cylinder 1002 and the protective shell 1004. The synchronous belt 15 passes through the slot laterally. A dustproof sponge is installed between the upper and lower sides of the inner wall of the slot. The synchronous belt 15 is located around the dustproof sponge. The dustproof sponge reduces the probability of dust entering the protective shell 1004 from the slot. At the same time, the dustproof sponge is used to wipe away the dust on the surface of the synchronous belt 15.
