Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly conveying equipment, and particularly to a multi-point automatic dust removal and environmentally friendly conveyor equipment. Background Art

[0002] In mining, conveyors are usually used to transport ore materials. To ensure that the conveying path fits the site, multiple conveyors are usually used in combination to form an ore material conveying line. As shown in the Figure 14 specification appendix, a prior art mine conveyor has guide rollers 02 evenly distributed between two side frames 03. A conveyor belt 01 is wound around each guide roller 02. By driving the conveyor belt 01 to run around the guide rollers 02, the ore materials can be transported. The cross-section of the conveyor belt 01 is designed in a V shape to prevent the ore materials from falling off the side of the conveyor belt 01.

[0003] When transporting ore materials, especially at the transfer point between conveyor belts, dust is easily generated due to the falling materials, and during the transportation process, dust is also easily generated due to the vibration of the conveyor belt. To avoid the dispersion of dust, a cover is usually provided on the side frame 03 and above the conveyor belt 01 to intercept and collect the dust. However, the covers in the prior art are usually fixedly installed. When replacing or debugging vulnerable parts such as the guide rollers 02 in the conveying equipment, in order to avoid the cover blocking the operation, the cover needs to be removed and reinstalled. Removing and reinstalling the cover takes a lot of time, the operation is cumbersome, which affects the maintenance efficiency of the ore material conveying equipment, and leads to an extension of the downtime for maintenance, affecting the production progress.

[0041] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] Example 1

[0043] See also Figures 1 - 14 The present invention provides a multi-point automatic dust removal environmentally friendly conveyor equipment, including two side frames 03 with guide rollers 02 evenly distributed between them and a conveyor belt 01 wound around the side frames 03. The mineral materials fall on the conveyor belt 01, and the conveyor belt 01 is driven to run around the guide rollers 02 to transport the mineral materials downstream.

[0044] A number of dust removal modules 1 are arranged at intervals along the length direction of the conveyor belt 01 above the two side frames 03. Among them, the dust removal module 1 is composed of a first cover 2 and a second cover 3. Both the first cover 2 and the second cover 3 are in an inverted U-shaped structure. One end of the second cover 3 is slidably fitted into the first cover 2. A first dust suction pipe 32 is connected to the first diversion port 31 at the top of each second cover 3. Each first dust suction pipe 32 is connected to an external dust collector. Among them, the dust collector adopts the existing technology and is not shown in the figure.

[0045] By the operation of the external dust collector to generate negative pressure, the dust scattered on the conveyor belt 01 and at the transfer points at both ends of the conveyor belt 01 can be sucked into the ash storage area in the dust collector through the first diversion ports 31 and the first dust suction pipes 32, realizing environmental protection dust removal during ore material transportation.

[0046] Two brackets 04 are fixed to the side of one side frame 03. A guide rod 05 is fixed between the two brackets 04. The side of each first cover 2 is fixed with a first sliding seat 06 through a connecting arm 08. The side of each second cover 3 is fixed with a second sliding seat 07 through a connecting arm 08. Each first sliding seat 06 and each second sliding seat 07 are slidably sleeved on the guide rod 05. By the sliding cooperation of the first sliding seat 06 and the second sliding seat 07 with the guide rod 05, each first cover 2 and each second cover 3 are capable of sliding along the length direction of the conveyor belt 01. In addition, the bottom end surfaces of each first cover 2 and each second cover 3 are in sliding contact with the top surface of the side frame 03, avoiding dust leakage and ensuring the dust removal effect.

[0047] An adjustment driving mechanism 4 is provided on the other side frame 03. Through the adjustment driving mechanism 4, the corresponding first covers 2 and second covers 3 at each position can be driven to slide and adjust in the opposite or same direction along the length direction of the conveyor belt 01. Specifically, the first covers 2 and second covers 3 in each dust removal module 1 slide and adjust in the opposite or same direction correspondingly.

[0048] Among them, as Figure 12 shown, when each first cover 2 and the corresponding second cover 3 are adjusted away from each other to the extreme position, each dust removal module 1 is connected in sequence to form a dust collection cover 09 with openings at both ends, and a dust collection flow channel 11 is formed between the dust collection cover 09 and above the conveyor belt 01. When the dust collector is working, a negative pressure is formed in the dust collection flow channel 11, and the air mixed with dust at the transfer points on both sides of the conveyor belt 01 can be sucked into the dust collection flow channel 11 and be pumped out together with the dust scattered on the conveyor belt 01, thereby realizing dust removal.

[0049] In addition, as Figure 13As shown, when each first cover 2 and the corresponding second cover 3 are adjusted close to each other, that is, the second cover 3 slides and retracts into the first cover 2, a clearance space 12 is formed between the two adjacent dust removal modules 1, that is, a gap is formed between the two adjacent dust removal modules 1, which is convenient for replacement or maintenance of components, so that there is no need to dismantle and reinstall the dust removal components as a whole.

[0050] In summary, the dust collecting hood 09 in the present application is formed by connecting several dust removal modules 1, and the first cover 2 and the second cover 3 in each dust removal module 1 can be adjusted by relative sliding. When each first cover 2 and the corresponding second cover 3 are adjusted close to each other, a clearance space 12 is formed between the two adjacent dust removal modules 1. Without the need to dismantle and reinstall the dust removal structure, the equipment components can be conveniently replaced or maintained. The replacement and maintenance operations are highly efficient and the downtime is short, thereby improving production efficiency.

[0051] In addition, the outer wall of the second cover 3 is slidably fitted with the inner wall of the first cover 2, that is, the outer walls on three sides of the second cover 3 are slidably fitted with the inner walls on three sides of the first cover 2. After long-term dust removal work, dust adheres to the inner walls of the first cover 2 and the second cover 3. By adjusting the first cover 2 and the second cover 3 close to each other, a clearance space 12 is formed between the two adjacent dust removal modules 1. When the second cover 3 retracts into the first cover 2, the dust on the inner wall of the first cover 2 can be scraped off due to the sliding fit of the second cover 3 and the inner wall of the first cover 2. In addition, the clearance space 12 can facilitate the cleaning of the dust on the inner wall of the second cover 3 and the rest of the first cover 2.

[0052] The first dust suction pipe 32 is a soft tube with the ability to bend and deform, and a certain length is reserved to adapt to the position change of the second cover 3 during sliding adjustment.

[0053] Example 2

[0054] See also Figure 3 、 Figure 5 and Figure 6 The difference between this embodiment and the first embodiment is that:

[0055] The adjustment drive mechanism 4 includes a drive device 5 and a transmission mechanism 6. The drive device 5 is provided on one side frame 03. The transmission mechanism 6 includes a plurality of worm-type sleeves 61, shafts 62, and worm wheels 63, the number and position of which correspond to each dust removal module 1. Each worm-type sleeve 61 is mounted on the drive device 5.

[0056] The shaft rods 62 are rotatably installed on the sides of the respective first covers 2 in a one-to-one correspondence. A worm gear 63 and a gear 64 are fixedly sleeved on each shaft rod 62. Each worm gear 63 meshes with a corresponding worm-type sleeve 61. A second rack 66 is fixed to the side of each first cover 2 through a fixing block 67. A first rack 65 is fixed to the side of each second cover 3 through a fixing block 67. The first rack 65 and the second rack 66 both mesh with the corresponding gear 64.

[0057] Specifically, the driving device 5 includes a rotating shaft 52 and a rocking disc 53. Mounting frames 51 are respectively fixed to both sides of one side frame 03. The rotating shaft 52 is rotatably installed on the two mounting frames 51. Each worm-type sleeve 61 is sleeved on the rotating shaft 52. The rocking disc 53 is installed on one end of the rotating shaft 52.

[0058] By rocking the rocking disc 53 to drive the rotating shaft 52 to rotate, the rotating rotating shaft 52 can drive each worm-type sleeve 61 to rotate simultaneously. The rotating worm-type sleeve 61 meshes with and drives the worm gear 63 and drives the shaft rod 62 and the gear 64 to rotate. Under the meshing transmission action of the rotating gear 64 with the first rack 65 and the second rack 66, the first cover 2 and the corresponding second cover 3 can be driven to slide towards or away from each other for adjustment, thereby realizing the retraction or extension adjustment of the dust removal module 1.

[0059] In addition, the one-way transmission of the worm-type sleeve 61 and the worm gear 63 is used to achieve a self-locking effect. When the rotating shaft 52 is not adjusted by rotation, the shaft rod 62 is prevented from rotating randomly, which helps to maintain the position states of the first cover 2 and the second cover 3 and prevents the first cover 2 and the second cover 3 from sliding randomly.

[0060] Embodiment 3

[0061] As Figure 6 and Figure 7 shown, the difference between this embodiment and Embodiment 2 is that:

[0062] Support frames 7 are rotatably sleeved on each worm-type sleeve 61 and near both ends thereof. A support plate 71 is fixed between the two support frames 7 on the same worm-type sleeve 61. Each shaft rod 62 respectively penetrates through the corresponding support plate 71 and is rotatably connected to the support plate 71. Since the shaft rod 62 is rotatably connected to the first cover 2, combined with the connection between the shaft rod 62 and the support plate 71, the connection between the support plate 71 and the support frame 7, and the connection between the support frame 7 and the worm-type sleeve 61, the relative position of the transmission mechanism 6 and the first cover 2 is fixed, and the first rack 65 and the gear 64 continuously maintain a meshing state.

[0063] In addition, each worm-type sleeve 61 is slidably mounted on the rotating shaft 52. The outer wall of the rotating shaft 52 has a positioning rib 521 extending along its length. The inner edge wall of each worm-type sleeve 61 is provided with a slide groove 611. The positioning rib 521 is correspondingly and slidably clamped in each slide groove 611, so that the worm-type sleeve 61 can be slidably adjusted along the surface of the rotating shaft 52. When the rotating shaft 52 rotates, the positioning rib 521 is clamped in the slide groove 611 to position the rotating shaft 52, thereby ensuring that the rotating shaft 52 can drive each worm-type sleeve 61 to rotate synchronously.

[0064] By utilizing the characteristic that the worm-type sleeve 61 can be slidably adjusted along the rotating shaft 52 and the sliding ability of the first cover 2 and the second cover 3, the whole formed by each dust removal module 1 and the corresponding transmission mechanism 6 can be slidably adjusted individually along the length direction of the conveyor belt 01, so that the position and size of the clearance space 12 formed between two adjacent dust removal modules 1 can be adjusted to facilitate the replacement or maintenance of components at different positions, with a high degree of flexibility.

[0065] Example 4

[0066] like Figure 12 As shown, the difference between this embodiment and the third embodiment is:

[0067] The side end of the first cover 2 corresponds to the side end of the second cover 3 in the adjacent dust removal module 1, that is, the ends of the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1 correspond to each other, playing a role of limiting blocking.

[0068] After the parts are replaced and maintained, and the first cover 2 and the second cover 3 are driven to move away from each other, the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1 can be naturally aligned and collided with each other, and the collision of corresponding points pushes each dust removal module 1 to move and adjust accordingly. There is no need to manually adjust the position of each dust removal module 1 one by one, so that the dust removal module 1 can adaptively reset to form the dust collecting hood 09, saving operation time. In addition, the end portions of the first cover 2 and the second cover 3 in the two adjacent dust removal modules 1 are in contact and fit to ensure the sealing between the two adjacent dust removal modules 1 and avoid dust leakage.

[0069] In addition, it is worth mentioning that when each dust removal module 1 is reset to form the dust collecting cover 09, that is, when the first cover 2 and the corresponding second cover 3 are away from each other to the limit position, Figure 2 As shown, the first slide 06 and the second slide 07 on the outermost side respectively interfere with the second slides 07 on both sides, thereby realizing automatic positioning of the dust collecting hood 09 and ensuring that the position of the dust collecting hood 09 is accurate.

[0070] Example 5

[0071] See also Figure 4 、 Figure 5 、Figure 8 and Figure 9 The difference between this embodiment and the fourth embodiment is that:

[0072] Each first cover 2 is provided with a clearance groove 21 extending along the length direction of the conveyor belt 01 at the position corresponding to the position of the first guide port 31, so that the first guide port 31 can move therein, that is, the clearance groove 21 is used to make space for the movement of the first guide port 31 to avoid obstruction and interference to the first guide port 31 when the second cover 3 retracts into the first cover 2.

[0073] Among them, the inner walls on both sides of the give way groove 21 are provided with a receiving groove 22 extending along the width direction of the conveyor belt 01, and each receiving groove 22 is slidably installed with a sealing plate 23. The ends of the two sealing plates 23 extending into the give way groove 21 can be completely spliced together to seal the give way groove 21 and prevent dust from leaking from the give way groove 21.

[0074] In addition, first springs 24 extending along the width direction of the conveyor belt 01 are fixed on the inner end walls opposite to each other in the two receiving grooves 22, and each first spring 24 is fixed to the side corresponding to the blocking plate 23, such as Figure 9 As shown, both sealing plates 23 have an arc-shaped notch 231 .

[0075] When the first cover 2 and the second cover 3 are moved away from each other to the extreme position, that is, when the dust removal module 1 is in a fully extended state, the elastic supporting force of the first spring 24 pushes the arc notches 231 on the two sealing plates 23 to match and fit the outer peripheral wall of the first guide port 31, ensuring that the sealing plates 23 and the first guide port 31 have a high degree of fit, thereby improving the dust leakage prevention effect. When the second cover 3 is retracted into the first cover 2, the first guide port 31 moves into the clearance groove 21, and the first guide port 31 pushes the sealing plate 23. The first spring 24 is compressed and accumulates force, and the sealing plate 23 retracts into the receiving groove 22, making space in the clearance groove 21 for the first guide port 31 to enter. When the first cover 2 and the second cover 3 are moved away from each other to the extreme position again, the elastic force of the first spring 24 is used to push the sealing plate 23 to return to its original position to seal the clearance groove 21 again.

[0076] In addition, the arc-shaped structure design of the arc-shaped notch 231 can generate arc-guided extrusion with the outer periphery of the first guide port 31, making it easier for the first guide port 31 to push the two blocking plates 23 twice to avoid jamming.

[0077] Example 6

[0078] See also Figure 10 and Figure 11 The difference between this embodiment and the fifth embodiment is that:

[0079] A scraping and dust removing mechanism 8 is arranged between the two side frames 03, below the conveyor belt 01 and near the downstream side of the conveyor belt 01. The scraping and dust removing mechanism 8 is used to clean and remove dust from the lower surface of the conveyor belt 01 during its return journey. The scraping and dust removing mechanism 8 includes a U-shaped cover 81 fixed between the two side frames 03, a box body 82 fixed inside the U-shaped cover 81 with an upward opening, an air bag body 83 installed on the box body 82, and a flexible scraping strip 84 installed on the top of the air bag body 83. The air bag body 83 is in an inflated state, and the shape of the flexible deformation surface 831 at the top is adapted to the lower surface of the conveyor belt 01. The flexible scraping strip 84 is installed on the flexible deformation surface 831 and is in sliding contact with the lower surface of the conveyor belt 01. A second dust suction pipe 812 is connected to the second diversion port 811 at the bottom of the U-shaped cover 81, and the second dust suction pipe 812 is connected to an external vacuum cleaner.

[0080] Among them, the flexible scraping strip 84 is made of a rubber strip, and it is detachably installed on the flexible deformation surface 831 (the specific detachable installation method adopts the existing technology and will not be elaborated in detail), so as to be replaced when the flexible scraping strip 84 is severely worn.

[0081] In addition, the air bag body 83 is fixed inside the box body 82. A gas chamber 85 is jointly formed inside the box body 82 and the air bag body 83. A cylinder body 86 is connected to the bottom of the box body 82 in a communicating manner. A piston 87 is slidably installed in the cylinder body 86 in a matching manner. A second spring 88 extending vertically is fixed on the inner bottom wall of the cylinder body 86, and the top end of the second spring 88 is fixed to the lower surface of the piston 87.

[0082] As Figure 12 shown, where the solid arrows in the figure indicate the air flow direction at each point during dust removal, and the dotted arrows indicate the running direction of the conveyor belt 01. When the conveyor belt 01 runs back above the scraping and dust removing mechanism 8, the flexible scraping strip 84 is tightly attached to the lower surface of the conveyor belt 01 due to the expansion support of the air bag body 83, and scrapes the dust attached to its surface as it moves with the conveyor belt 01, peeling the dust from the surface of the conveyor belt 01. The peeled dust falls into the U-shaped cover 81 and is sucked by the external vacuum cleaner through the second diversion port 811 and the second dust suction pipe 812. Among them, the two sides of the U-shaped cover 81 are open for air intake, and finally converge into the second diversion port 811, improving the dust capture effect and preventing some dust from staying in the U-shaped cover 81 and causing incomplete dust removal.

[0083] In addition, the upper dust collection cover 09 and the first dust suction pipe 32 cooperate with the lower scraping and dust removing mechanism 8 to achieve the all-round collection of dust at the conveyor belt 01 during ore material conveying, return journey and transfer, and the environmental protection effect is remarkable.

[0084] The flexible deformation surface 831 of the air bag body 83 adapts and adjusts according to the slight vibration or shape change of the conveyor belt 01, ensuring that the flexible scraping strip 84 always adheres to the lower surface of the conveyor belt 01 and avoiding the failure of the adhesion and cleaning.

[0085] When the conveyor belt 01 presses downward on the airbag body 83, the airbag body 83 is compressed, the volume of the air chamber 85 decreases, and the internal air is pressed and flows downward into the cylinder body 86, pushing the piston 87 to slide downward against the elastic force of the second spring 88, and the second spring 88 is compressed. When the conveyor belt 01 moves upward, the airbag body 83 expands under the action of its own elasticity and the second spring 88 resetting to push the piston 87 upward for gas replenishment, the volume of the air chamber 85 is restored, and the flexible scraping strip 84 is pushed to fit closely to the lower surface of the conveyor belt 01, realizing the adaptive dynamic adjustment of the flexible scraping strip 84.

[0086] The flexible deformation of the airbag body 83 combined with the buffer structure formed by the piston 87 and the second spring 88 enables the flexible scraping strip 84 to perform adaptive dynamic adjustment following the fluctuations in the shape of the conveyor belt 01, thereby ensuring that the flexible scraping strip 84 can continuously adhere to the lower surface of the conveyor belt 01 and ensuring stable cleaning effect.

[0087] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
