Description

Technical Field

[0001] The invention relates to the technical field of dust removal devices, in particular to a small particle recovery and dust removal device for silicon dioxide production. Background Art

[0002] A dust removal device refers to a device that separates and captures solid pollutants such as dust and particulate matter from industrial production processes, ambient air or other gas flows through physical, chemical or mechanical means to purify the gas and reduce pollutant emissions. There are many types of dust removal devices, and the corresponding dust removal equipment needs to be selected according to the different industrial production needs. For example, when dealing with small particles of dust generated by silica production equipment, a bag dust removal device is required.

[0003] At present, when the existing bag dust removal equipment is in use, the filter bags in the bag dust removal equipment need to be replaced regularly. In order to ensure that the filter bags do not dry out, the filter bags are provided with frames inside. However, the number of frames is large and the size is long, and they cannot be folded. Therefore, multiple people need to cooperate with each other during replacement, which not only wastes manpower and material resources, but also wastes a lot of time, thereby increasing the downtime of the equipment and greatly reducing the dust removal efficiency.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the small particle recovery and dust removal devices currently available on the market for silica production.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 9-11 The present invention provides a technical solution: a small particle recovery and dust removal device for silicon dioxide production, comprising a dust removal bin 1, a pipe transverse movement mechanism 2 is provided inside the dust removal bin 1, and a skeleton removal mechanism 3 is provided inside the dust removal bin 1; The pipeline transverse movement mechanism 2 can move the pipeline in position.

[0023] As a further limitation of the pipeline transverse movement mechanism 2 of the present invention, the pipeline transverse movement mechanism 2 includes two first hydraulic rods 202, the telescopic end of each first hydraulic rod 202 is fixedly connected to a connecting plate 205, the inner walls of the two connecting plates 205 are commonly fixedly connected to a pulse pipe 201, each first hydraulic rod 202, the connecting plate 205 and the pulse pipe 201 are all arranged inside the dust removal bin 1, and the right side of the dust removal bin 1 is fixedly connected to a rectangular box 206, the inner wall of the rectangular box 206 is fixedly connected to an electromagnetic pulse valve 208, and the outer surface of the electromagnetic pulse valve 208 and the outer surface of the pulse pipe 201 are fixedly connected. The first gear 203 is commonly threadedly connected to the surface, and the inner wall of the rectangular box 206 is fixedly connected to the second hydraulic rod 207. The telescopic end of the second hydraulic rod 207 is fixedly connected to the first tooth plate 204. The outer surface of the first tooth plate 204 is engaged with the outer surface of the first gear 203. By setting up a pipeline transverse movement mechanism 2, the pipeline transverse movement mechanism 2 can control the transverse movement of the pulse pipeline 201 inside the equipment, so that the pulse pipeline 201 is not directly above the filter bag 3120, thereby eliminating the step of disassembling the pulse pipeline 201 and further increasing the replacement efficiency of the filter bag 3120.

[0024] See also Figure 9 The outer surface of each first hydraulic rod 202 is fixedly connected to the inner wall of the dust removal bin 1, and the bottom surface of each connecting plate 205 is in contact with the outer surface of the dust removal bin 1. Since the bottom surface of the connecting plate 205 is in contact with the surface of the dust removal bin 1, the stability of the connecting plate 205 can be guaranteed when following the movement of the first hydraulic rod 202.

[0025] The specific implementation of this embodiment is: when the filter bag 3120 in the equipment needs to be replaced and the position of the pulse pipe 201 needs to be adjusted, it is necessary to control the operation of the second hydraulic rod 207, and utilize the meshing connection relationship between the first tooth plate 204 and the first gear 203. The first gear 203 can move toward the direction of the electromagnetic pulse valve 208 under the action of the tooth plate until the first gear 203 no longer has a threaded connection relationship with the outer surface of the pulse pipe 201. At this time, the operation of the first hydraulic rod 202 can pull the connecting plate 205 and the pulse pipe 201 to move, so that the outlet end of the pulse pipe 201 moves to the position between the two filter bags 3120.

[0026] Example 2: Please refer to Figures 1-6The present invention provides a technical solution: a small particle recovery and dust removal device for silica production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The skeleton dismantling mechanism 3 includes a dismantling unit 31. The skeleton dismantling mechanism 3 includes a dismantling unit 31. The dismantling unit 31 includes a moving box 3101. The moving box 3101 is arranged inside the dust removal bin 1. The inner top wall of the moving box 3101 is fixedly connected to a plurality of identical first rectangular plates 3105. The outer surface of each first rectangular plate 3105 is fixedly connected to two first rectangular blocks 3114. The inner walls of each group of first rectangular blocks 3114 are jointly rotatably connected to a first spring return shaft 3115. The outer surface of each first spring return shaft 3115 is fixedly connected to a first flip plate 3116.

[0027] As a further limitation of the skeleton dismantling mechanism 3 of the present invention, two first stepper motors 3110 are fixedly connected to the inner side wall of the dismantling box 3101, and the output end of each first stepper motor 3110 is fixedly connected to the first threaded shaft 3111, and the outer surfaces of the two first threaded shafts 3111 are commonly threadedly connected to the lifting frame 3112, and the bottom surface of the lifting frame 3112 is fixedly connected to a plurality of identical second rectangular plates 3113, and the outer surface of each second rectangular plate 3113 is fixedly connected to two second rectangular blocks 3119, and the inner wall of each group of second rectangular blocks 3119 is rotatably connected to the second spring return shaft 3118, and the outer surface of each second spring return shaft 3118 is fixedly connected to the second flip plate 3117. By setting up a disassembly unit 31, the disassembly unit 31 can be used to batch dismantle the support skeletons 3121 inside the filter bags 3120, and after batch disassembly, these support skeletons 3121 can also provide short-term support force, leaving enough time for workers to replace new filter bags 3120.

[0028] See also Figure 1 The left side of the dust removal bin 1 is fixedly connected to a fan 3104, and the input end of the fan 3104 is fixedly connected to the left side of the dust removal bin 1. By providing the fan 3104, the fan 3104 can guide the gas inside the equipment to flow out to the outside.

[0029] See also Figure 1 and Figure 7 The right side of the dust removal bin 1 is fixedly connected with a connecting pipe 3123, which can directly transport the gas to be processed to the lower half of the dust removal bin 1. The connecting pipe 3123 can guide the air containing fine particles into the interior of the dust removal bin 1 for dust removal.

[0030] See also Figure 1-Figure 3Two second stepper motors 3103 are fixedly connected to the left side of the dust removal bin 1, and the output end of each second stepper motor 3103 is fixedly connected to the second threaded shaft 3102. The outer surface of each second threaded shaft 3102 is rotatably connected to the inner wall of the dust removal bin 1, and the outer surfaces of the two second threaded shafts 3102 are commonly threadedly connected to the inner wall of the moving box 3101. By providing a second stepper motor 3103, the second stepper motor 3103 can provide power for the rotation of the second threaded shaft 3102, thereby driving the moving box 3101 to move.

[0031] See also Figure 7 The inner wall of the dust removal bin 1 is fixedly connected with a square plate 3122, and a number of identical filter bags 3120 are clamped inside the square plate 3122. The outer surface of each filter bag 3120 is in contact with the upper surface of the square plate 3122. A support frame 3121 is provided inside each filter bag 3120, and the outer surface of each support frame 3121 is in contact with the inner wall of the filter bag 3120. The upper surface of each support frame 3121 is fixedly connected with a circular ring 3108, and the bottom surface of each circular ring 3108 is in contact with the upper surface of the filter bag 3120. By providing the filter bags 3120, dust in the air can be filtered, and the existence of the support frame 3121 can prevent the filter bags 3120 from deformation.

[0032] See also Figure 8 The upper surface of each circular ring 3108 is provided with two groups of rectangular grooves 3107 and two semicircular grooves 3106, and the number of each group of rectangular grooves 3107 is two. The outer surface of each circular ring 3108 is provided with a limiting groove 3109. By setting the limiting groove 3109, the limiting groove 3109 can provide a grasping position for the second flip plate 3117.

[0033] The specific implementation of this embodiment is as follows: after the pulse pipe 201 has been moved, the worker can open the movable door on the top of the dust removal bin 1, climb into the interior of the dust removal bin 1, and then control the second stepper motor 3103 to operate. The operation of the second stepper motor 3103 will drive the second threaded shaft 3102 to rotate. The threaded connection between the second threaded shaft 3102 and the movable box 3101 can be used to drive the movable box 3101 to move horizontally. When the middle part of the movable box 3101 moves to the top of the filter bag 3120, the first stepper motor 3110 can be controlled to operate. The operation of the first stepper motor 3110 also utilizes the first threaded shaft 3111 and the lifting The threaded connection relationship of the lowering frame 3112 can drive the lifting and lowering. When the second flip plate 3117 moves downward to the position in contact with the circular ring 3108, the second flip plate 3117 will flip toward the second rectangular plate 3113. As the second flip plate 3117 continues to descend, when the second flip plate 3117 descends to the position of the limiting groove 3109, the second flip plate 3117 is no longer limited by the circular ring 3108. Therefore, the second flip plate 3117 will be reset under the action of the second spring reset shaft 3118. Then the first stepper motor 3110 runs in the reverse direction to drive the second flip plate 3117 and the circular ring 3108 to move upward. The support frame 3121 can be pulled to move upward. It should be understood that the support frame 3121 is composed of a plurality of annular frames and long strip frames. Therefore, when the second flip plate 3117 pushes the support frame 3121 and the circular ring 3108 to move upward and pass through the first flip plate 3116, the first flip plate 3116 will be pushed to flip toward the position of the first rectangular plate 3105. When the circular ring 3108 moves to the top of the first flip plate 3116, the first flip plate 3116 will be reset under the action of the first spring return shaft 3115. At this time, the first stepper motor 3110 will rotate in the opposite direction again, prompting the second flip plate 3117 to move downward again. When the filter bag 3120 is in the filter bag 3120, the first stepper motor 3110 will move in the opposite direction, and the second stepper motor 3110 will move upward to move the second flip plate 3117. In the process of moving upward, the second flip plate 3117 will contact the annular frame again, pushing the annular frame to further push the support frame 3121 to move upward, and repeating the cycle to achieve the purpose of pulling the support frame 3121 out of the filter bag 3120.

[0034] Example 3: Please refer to Figure 3 and Figure 4The present invention provides a technical solution: a small particle recovery and dust removal device for silica production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The skeleton dismantling mechanism 3 also includes a reset unit 32. The reset unit 32 is arranged inside the dust removal bin 1. The reset unit 32 can enable the skeleton to provide support for the replaced filter bag again.

[0035] As a further limitation of the skeleton dismantling mechanism 3 of the present invention, the reset unit 32 includes two first telescopic rods 3202 and two second telescopic rods 3203. The outer surface of each first telescopic rod 3202 and the second telescopic rod 3203 is fixedly connected to the inner wall of the movable box 3101. The telescopic ends of the two first telescopic rods 3202 are commonly fixedly connected to the limiting plate 3206. The telescopic ends of the two second telescopic rods 3203 are commonly fixedly connected to the long plate 3207. The left side of the long plate 3207 is fixedly connected to several identical transmission tooth plates 3201. The inner wall of the movable box 3101 is rotatably connected to several identical rotating rings 3204. The outer surface of each rotating ring 3204 is fixedly connected to a transmission gear 3205. By providing the mutual cooperation between the pipeline transverse movement mechanism 2, the disassembly unit 31 and the reset unit 32, it can be effectively avoided that when the equipment is in use, the replacement steps of the filter bag 3120 are complicated and cumbersome, resulting in a long equipment downtime and reducing the dust filtration efficiency.

[0036] The specific implementation of this embodiment is as follows: due to the special structure of the support frame 3121, the overall length is long, the number is large, and the internal space of the dust removal equipment is limited, the support frame 3121 cannot be taken out by using a telescopic rod, a hydraulic rod or a driving screw. When the disassembly unit 31 pushes the support frame 3121 to move upward, the circular ring 3108 above the support frame 3121 will move to the bottom of the rotating ring 3204. As the support frame 3121 continues to move upward, a semicircular limiting structure protruding from the inner ring of the rotating ring 3204 will pass through the semicircular groove 3106 opened on the upper surface of the circular ring 3108. Figure 4 It can be seen that the inner ring of each rotating ring 3204 has two protruding semicircular limiting structures. At this time, the semicircular limiting structures of the inner ring of the rotating ring 3204 will contact the surface of the long frame. It should be understood here that the semicircular limiting structures fixed on the inner ring of the rotating ring 3204 will not affect the rise of the supporting frame 3121. Figure 8It can be seen that the radius of the long frame is much larger than the annular frame. Therefore, when the support frame 3121 moves upward, the long frame will move upward along the semicircular limiting structure. The semicircular limiting structure can provide the long frame with left and right force limitation, but does not provide up and down force limitation. Therefore, the semicircular limiting structure does not affect the rise of the support frame 3121. On the contrary, when the rotating ring 3204 rotates, the rotational power can be transmitted to the support frame 3121, driving the support frame 3121 to rotate. When the support frame 3121 is completely pulled out from the filter bag 3120, the worker can disassemble the filter bag 3120 that needs to be replaced, and then install the new filter bag 3120 to the original replaced one. After the filter bag 3120 is replaced with a new filter bag 3120, the movable box 3101 can be controlled to return to the top of the new filter belt, and then the first stepper motor 3110 can be controlled to operate, driving the second flip plate 3117 to push the support frame 3121 to move upward, and the second ring frame from the bottom is moved to the position of the first flip plate 3116, and after squeezing the first flip plate 3116 in the direction of the first rectangular plate 3105, the first telescopic rod 3202 will pull the limit plate 3206 to move to the left. At this time, the limit plate 3206 can provide supporting force for a certain ring frame in the support frame 3121, and then the first stepper motor 3110 is controlled to reset. At this time, the first stepper motor 3110 will The second flip plate 3117 is driven downward again. When the second flip plate 3117 moves to the position of the lowermost annular frame, the second flip plate 3117 and the first flip plate 3116 are folded inside the second rectangular plate 3113 and the first rectangular plate 3105 respectively. Then the second telescopic rod 3203 is controlled to operate. The operation of the second telescopic rod 3203 can drive the transmission gear plate 3201 to move to the left. The transmission gear plate 3201 will engage with the surface of the transmission gear 3205, driving the transmission gear 3205 to rotate thirty degrees. It can be understood here that when the transmission gear 3205 rotates thirty degrees, the rotating ring 3204 and the supporting frame 3121 and the circular ring 3108 inside the rotating ring 3204 will also rotate. Thirty degrees, at this time, the first flip plate 3116 and the second flip plate 3117 are both on one side of the long frame, and these long frames are under the rectangular groove 3107, and the size of the rectangular groove 3107 is larger than the first flip plate 3116 and the second flip plate 3117. Therefore, the first flip plate 3116 and the second flip plate 3117 will always be limited by the long frame and will not be reset under the action of the first spring return shaft 3115 and the second spring return shaft 3118. Then the first telescopic rod 3202 is controlled to push the limit plate 3206 to reset to the right. At this time, the limit plate 3206 will not provide any supporting force to the support frame 3121, so the support frame 3121 will move downward under the action of gravity, butThe long strips of support frame 3121 create friction with the surfaces of first flip plate 3116 and second flip plate 3117. This friction slows down the descent of support frame 3121. As a result, when rectangular slot 3107 moves downward, it eventually passes through first flip plate 3116 and second flip plate 3117, allowing first flip plate 3116 and second flip plate 3117 to break away from contact with support frame 3121, thus completing the installation of support frame 3121.
