Description

Technical Field

[0001] This invention relates to the field of dust treatment technology, specifically to a dust collection and treatment device for dry purification of wollastonite. Background Technology

[0002] During the dry purification process of wollastonite, a large amount of dust is generated during the crushing of wollastonite, which needs to be collected and treated using a dust collection and treatment device.

[0003] Existing dust collection and treatment devices typically use a fan to draw dust-laden air into a chamber, then use a combination of spray dust suppression and filters to clean the dust particles in the air before discharging the cleaned gas. However, this method is inconvenient for exporting and further processing the collected dust. Moreover, the moistened dust after spraying may accumulate in the filter channels of the filter, affecting the gas export and hindering continuous dust collection and treatment. In addition, spray dust suppression cannot uniformly remove dust from the air, and blind spots can easily appear in the corners of the chamber, resulting in dust residue in the discharged air and reducing the dust collection efficiency.

[0004] Therefore, there is a need to provide a dust collection and treatment device for the dry purification of wollastonite, which aims to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a dust collection and treatment device for dry purification of wollastonite, so as to solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0012] As a further embodiment of the present invention, the flattening assembly includes a flattening plate slidably disposed on one end of the guide post near the chassis. The outer diameter of the flattening plate is the same as the inner diameter of the collecting pipe. The side of the flattening plate away from the chassis is provided with an inverted conical surface. A plurality of grooves are distributed circumferentially on the outer edge of the flattening plate. A plurality of flattening slots are distributed circumferentially on the side of the flattening plate near the chassis. The grooves and flattening slots correspond to each other. A retaining ring is provided on the guide post between the flattening plate and the lifting seat. A spring sleeved on the outside of the guide post is connected between the flattening plate and the retaining ring.

[0013] As a further embodiment of the present invention, a support is installed at the bottom of the processing box, and a protective cover is installed on one end of the exhaust pipe extending out of the processing box, the protective cover being umbrella-shaped.

[0014] As a further embodiment of the present invention, the dimensions of gear one, gear ring and gear two increase sequentially.

[0015] As a further embodiment of the present invention, the electrode plate is configured as a corrugated plate and includes a negative electrode plate and a positive electrode plate. The negative electrode plate and the positive electrode plate are spaced apart and circumferentially distributed on the outside of the exhaust pipe. The distance between the ends of adjacent negative electrode plates and positive electrode plates closest to the exhaust pipe is the smallest and is between 25-35cm. The distance between the ends of adjacent negative electrode plates and positive electrode plates furthest from the exhaust pipe is the largest and is between 115-125cm.

[0016] As a further embodiment of the present invention, there are three grooves and three flattening grooves. The flattening groove is a V-shaped arc groove, and the included angle between the lines connecting the two ends of the flattening groove to the center of the bottom of the groove is 120 degrees.

[0017] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0018] 1. In this invention, the motor drives gear one to rotate, gear one drives the exhaust pipe to rotate by meshing with the gear ring, the gear ring drives the slide column one to rotate synchronously by meshing with gear two, the slide column one drives the air guide pipe to reciprocate by sliding with the movable swing plate and rotating with the air guide pipe and the processing box, the air guide pipe drives the air outlet to swing synchronously, and the air guide plate can guide the air outlet to oscillate synchronously. By setting the air guide plate, the air outlet can be guided to avoid the gas being blown directly towards the exhaust pipe, which helps to increase the distance that dust moves to the exhaust pipe, extend the dust removal time, and improve the dust removal effect;

[0019] 2. In this invention, the electrode plate is set as a corrugated plate and includes a negative electrode plate and a positive electrode plate. The negative electrode plate and the positive electrode plate are spaced apart and circumferentially distributed on the outside of the exhaust pipe. The rotating component drives the electrode plate to rotate synchronously by driving the exhaust pipe to rotate, which facilitates the uniform adsorption of dust particles in the gas by the electrode plate, avoids dust accumulation in a certain place on the electrode plate, and improves dust removal efficiency.

[0020] 3. In this invention, the rotating component drives the exhaust pipe to rotate. The exhaust pipe drives the lifting seat to rotate synchronously through connection with the guide column and sliding engagement between the guide column and the lifting seat. The lifting seat achieves reciprocating lifting by sliding engagement between the sliding column two and the guide ring groove and connection between the fixed sleeve and the inner wall of the processing box. The lifting seat drives the cleaning brush to reciprocate synchronously through connection between the upright and the cleaning brush. The cleaning brush cleans the dust adhering to the outer wall of the electrode plate by contacting the outer wall of the electrode plate, avoiding dust accumulation on the surface of the electrode plate and helping to improve the subsequent dust adsorption efficiency. At the same time, the linkage between the rotating component and the cleaning component is realized, reducing the power source.

[0021] 4. In this invention, the dust cleaned by the cleaning component falls into the collection pipe and moves along the conical and groove surfaces to the space between the flattening groove and the base. The rotating component drives the exhaust pipe to rotate, and the exhaust pipe drives the guide column to rotate and the flattening plate to rotate synchronously through the sliding cooperation between the guide column and the flattening plate. The flattening plate flattens the dust that falls between the flattening groove and the base. When the dust fills the space between the flattening groove and the base, the dust pushes the flattening plate to slide away from the base along the guide column. The spring is stressed and contracts. At the same time, the flattening plate continues to rotate and continuously flattens the dust that falls between the flattening groove and the base. This can achieve centralized collection and treatment of dust, and at the same time, realize the linkage between the rotating component, the cleaning component, the flattening process and the closing component.

[0022] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] In one embodiment of the present invention, see Figure 1 and Figure 2 A dust collection and treatment device for dry purification of wollastonite includes a treatment box 1, a collection pipe 11 at the bottom of the treatment box 1, a closing assembly 8 at the bottom of the collection pipe 11, an air inlet pipe 2 on the treatment box 1, a guide pipe 21 rotatably connected inside the treatment box 1, one end of the guide pipe 21 rotatably connected to the air inlet pipe 2, a plurality of air outlets 22 longitudinally distributed on the guide pipe 21, an exhaust pipe 3 rotatably connected inside the treatment box 1, and a rotating assembly 4 on the treatment box 1 connected to the exhaust pipe 3 and the guide pipe 21. The top of the exhaust pipe 3 penetrates the top of the treatment box 1 and is connected to the outside air. The exhaust pipe 3 has several filter holes 31 distributed circumferentially. A dust removal component 5 is provided on the exhaust pipe 3 inside the treatment box 1. A guide plate 13 is provided inside the treatment box 1 between the air guide pipe 21 and the dust removal component 5. A cleaning component 6 connected to the exhaust pipe 3 is provided at the bottom inside the treatment box 1. The cleaning component 6 is used to remove dust adhering to the dust removal component 5. A flattening component 7 is provided inside the collection pipe 11 between the cleaning component 6 and the closing component 8.

[0036] In this embodiment, the dust generated during the dry purification of wollastonite can be drawn into the processing box 1 by the cooperation of the air inlet pipe 2 and the external suction pump. The rotating component 4 adjusts the air direction of the intake gas by driving the air guide pipe 21 to swing back and forth, avoiding the inability to remove dust evenly due to a single air direction. The rotating component 4, the dust removal component 5 and the filter hole 31 can uniformly adsorb and remove dust from the intake gas, preventing dust from accumulating in one place of the dust removal component 5 and improving dust removal efficiency. The rotating component 4, the cleaning component 6 and the exhaust pipe 3 can automatically clean the dust adsorbed on the dust removal component 5. The flattening component 7 and the closing component 8 can collect and flatten the fallen dust. The closing component 8 can discharge the flattened dust, which is convenient for subsequent dust flattening. It has the effects of air direction adjustment, efficient and uniform dust removal, automatic cleaning, centralized collection, efficient flattening, simple structure, convenient operation and practicality.

[0037] The bottom of the treatment box 1 is equipped with a support 12, which can effectively support the bottom of the device. The exhaust pipe 3 is equipped with a protective cover 32 at one end extending out of the treatment box 1. The protective cover 32 is umbrella-shaped to prevent external dust from falling into the exhaust pipe 3.

[0038] In one embodiment of the present invention, see Figures 1-3 The rotating assembly 4 includes a gear 42 rotatably mounted on the top inner side of the processing box 1. The gear 42 is connected to a motor 41 mounted on the processing box 1. A gear ring 43 that meshes with the gear 42 is fixedly mounted on the outer side of the exhaust pipe 3. A gear 44 that meshes with the gear ring 43 is rotatably mounted on the top inner side of the processing box 1. The gear 44 is located between the motor 41 and the exhaust pipe 3. A sliding column 45 is provided on one outer edge of the gear 44. A movable swing plate 46 that slides with the sliding column 45 is mounted on the air guide pipe 21.

[0039] In this embodiment, motor 41 drives gear 42 to rotate. Gear 42 meshes with gear ring 43 to drive exhaust pipe 3 to rotate. Exhaust pipe 3 drives dust removal assembly 5 to rotate synchronously, which can remove dust from the gas inside the treatment box 1. At the same time, gear ring 43 meshes with gear 44 to drive slide column 45 to rotate synchronously. Slide column 45 slides with movable swing plate 46 and drives air guide pipe 21 to oscillate back and forth through sliding engagement with air guide pipe 21 and rotational engagement with treatment box 1. Air guide pipe 21 drives air outlet 22 to oscillate synchronously. With the setting of air guide plate 13, the air outlet 22 can be guided to avoid the gas being directly blown into exhaust pipe 3. This helps to increase the distance that dust moves to exhaust pipe 3, prolong the dust removal time, and improve the dust removal effect.

[0040] The dimensions of gear 42, gear ring 43, and gear 44 increase sequentially, which helps to stagger the correspondence between the air outlet 22 and the dust removal component 5, thereby achieving uniform dust removal.

[0041] In one embodiment of the present invention, see Figures 1-2 and Figure 4 The dust removal component 5 includes several mounting slots 51 circumferentially distributed on the outside of the exhaust pipe 3. The mounting slots 51 are located inside the processing box 1, and electrode plates 52 are mounted on the mounting slots 51.

[0042] In this embodiment, the electrode plate 52 is a corrugated plate and includes a negative electrode plate and a positive electrode plate. The negative electrode plate and the positive electrode plate are spaced apart and circumferentially distributed on the outside of the exhaust pipe 3. The distance between the ends of adjacent negative electrode plates and positive electrode plates closest to the exhaust pipe 3 is the smallest and the distance is between 25-35cm. The distance between the ends of adjacent negative electrode plates and positive electrode plates furthest from the exhaust pipe 3 is the largest and the distance is between 115-125cm.

[0043] As the electrode spacing increases, the conductive distance in the electric field space increases, and the rate of potential change decreases. However, the electric field strength may increase within a certain range with the increase in spacing, and the electric field strength distribution becomes more uniform. Generally, the efficient electrode spacing range is between 300mm and 1200mm. Within this range, the dust driving speed increases proportionally with the electrode spacing, thereby compensating for the reduction in dust collection area caused by the decrease in the number of channels. Therefore, the spaced cathode and anode plates in this embodiment can efficiently adsorb dust particles.

[0044] Meanwhile, the wavy electrode plate 52 can prolong the gas flow time and improve the dust removal efficiency, and the filter holes 31 facilitate the export of purified gas.

[0045] In one embodiment of the present invention, see Figures 1-5 and Figure 8 The cleaning assembly 6 includes a fixed sleeve 61 movably sleeved on the outside of the exhaust pipe 3. The fixed sleeve 61 is connected to the inner wall of the treatment box 1. The inner wall of the fixed sleeve 61 is provided with an inclined guide ring groove 611. The bottom of the exhaust pipe 3 is connected to a guide post 63 movably disposed inside the fixed sleeve 61. A lifting seat 62 movably disposed inside the fixed sleeve 61 is slidably disposed on the guide post 63. The outer end of the lifting seat 62 is provided with a sliding column 621 that slidably engages with the guide ring groove 611. Several cleaning brushes 65 are symmetrically and longitudinally distributed on both sides of the electrode plate 52. The longitudinally distributed cleaning brushes 65 are connected to the uprights 64 connected to the lifting seat 62.

[0046] In this embodiment, the motor 41 drives the gear 42 to rotate. The gear 42 meshes with the gear ring 43 to drive the exhaust pipe 3 to rotate synchronously. The exhaust pipe 3 is connected to the guide column 63 and the guide column 63 slides with the lifting seat 62 to drive the lifting seat 62 to rotate synchronously. The lifting seat 62 is reciprocated by sliding the sliding column 621 with the guide ring groove 611 and by connecting the fixed sleeve 61 with the inner wall of the processing box 1. The lifting seat 62 is connected to the cleaning brush 65 by the upright 64 to drive the cleaning brush 65 to reciprocate synchronously. The cleaning brush 65 cleans the dust adhering to the outer wall of the electrode plate 52 by contacting the outer wall of the electrode plate 52, avoiding the accumulation of dust on the surface of the electrode plate 52, which helps to improve the subsequent dust adsorption efficiency. The cleaned dust falls into the collection pipe 11 and is flattened by the flattening component 7.

[0047] The guide post 63 has a strip groove along its length, and the lifting seat 62 has a sliding strip that slides in conjunction with the strip groove. The upper and lower ends of the guide ring groove 611 are both set as residual ring grooves with an arc corresponding to the arc of the inner wall of the fixed sleeve 61. Through the sliding contact between the guide ring groove 611 and the sliding post 621, the dust adhering to the surface of the electrode plate 52 can be cleaned repeatedly during the rotation of the electrode plate 52, which facilitates the continuous adsorption of the electrode plate 52. At the same time, the linkage between the dust removal component 5 and the cleaning component 6 is realized, saving energy consumption. In addition, an arc-shaped brush can be connected between the cleaning brushes 65 on both sides of the filter hole 31. The cleaning brushes 65 clean the filter hole 31 by driving the arc-shaped brush to rise and fall synchronously, avoiding dust accumulation at the filter hole 31 and facilitating the exhaust of purified gas.

[0048] In one embodiment of the present invention, see Figures 1-2 , Figures 6-7 The closing assembly 8 includes a connecting seat 81 disposed on the outer side of the bottom of the collecting tube 11. A base 82 corresponding to the movement of the bottom of the collecting tube 11 is rotatably connected to the connecting seat 81. A connecting seat 85 is provided at the bottom of the collecting tube 11 away from the connecting seat 81. A rotating rod 84 is rotatably provided on the connecting seat 85. One end of the rotating rod 84 is connected to a support plate 83 that moves and abuts against the bottom of the base 82 away from the connecting seat 81. A lever 86 is connected to the end of the connecting seat 85 away from the support plate 83.

[0049] In this embodiment, in the initial state, the bottom of the chassis 82 corresponds to the bottom of the collection tube 11, and the tray 83 is in contact with the end of the chassis 82 away from the connecting seat 81, which can close the bottom of the collection tube 11. When the dust inside the collection tube 11 is flattened and needs to be discharged, the lever 86 is pulled outward. The lever 86 drives the tray 83 to rotate outward through the rotating rod 84, releasing the contact between the tray 83 and the chassis 82. Then, the chassis 82 is rotated outward around the connecting seat 81, releasing the correspondence between the chassis 82 and the bottom of the collection tube 11. The flattened dust inside the collection tube 11 will move downward under its own weight and the pressing action of the flattening component 7, realizing the centralized collection of dust, which is convenient for subsequent processing.

[0050] In one embodiment of the present invention, see Figures 1-3 , Figure 6 , Figures 8-9 The flattening assembly 7 includes a flattening plate 71 slidably disposed on one end of the guide post 63 near the base plate 82. The outer diameter of the flattening plate 71 is the same as the inner diameter of the collecting pipe 11. The side of the flattening plate 71 away from the base plate 82 is provided with an inverted conical surface 711. Several grooves 712 are distributed circumferentially on the outer edge of the flattening plate 71. Several flattening grooves 713 are distributed circumferentially on the side of the flattening plate 71 near the base plate 82. The grooves 712 and flattening grooves 713 correspond to each other. The guide post 63 is provided with a retaining ring 72 located between the flattening plate 71 and the lifting seat 62. A spring 73 sleeved on the outside of the guide post 63 is connected between the flattening plate 71 and the retaining ring 72.

[0051] In this embodiment, the dust cleaned by the cleaning component 6 falls into the collection pipe 11 and moves along the surface of the conical surface 711 and the groove 712 to the space between the flattening groove 713 and the chassis 82. The motor 41 drives the gear 42 to rotate. The gear 42 drives the exhaust pipe 3 to rotate by meshing with the gear ring 43. The exhaust pipe 3 drives the guide column 63 to rotate and the guide column 63 slides with the flattening plate 71 to drive the flattening plate 71 to rotate synchronously. The flattening plate 71 flattens the dust that falls between the flattening groove 713 and the chassis 82. When the dust piles up... After the space between the flattening groove 713 and the chassis 82 is filled, the dust will push the flattening disc 71 to slide away from the chassis 82 along the guide column 63. The spring 73 will be stressed and contract. At the same time, the flattening disc 71 will continue to rotate and continuously flatten the dust that falls between the flattening groove 713 and the chassis 82. After flattening for a period of time, the staff will rotate the chassis 82 to release the closure at the bottom of the collection pipe 11, so that the flattened dust can be discharged. Then the chassis 82 will be rotated back to realize the re-closure of the bottom of the collection pipe 11, thereby flattening the subsequent dust.

[0052] The rotation of the flattening disc 71 centrifuges the dust falling onto the conical surface 711. The dust is thrown out and falls along the groove 712 into the flattening groove 713 and the base plate 82, facilitating the collection and treatment of the dust. There are three grooves 712 and three flattening grooves 713. The flattening groove 713 is a V-shaped arc groove. The angle between the lines connecting the two ends of the flattening groove 713 to the bottom center of the groove 712 is 120 degrees. The rotation of the flattening disc 71 will cause the edges of two adjacent flattening grooves 713 to rotate synchronously, thereby flattening the dust.

[0053] Specifically:

[0054] With the cooperation of the air inlet pipe 2 and the external suction pump, the dust generated during the dry purification of wollastonite can be sucked into the processing box 1. The motor 41 drives the gear 42 to rotate. The gear 42 drives the exhaust pipe 3 to rotate by meshing with the gear ring 43. At the same time, the gear ring 43 drives the slide column 45 to rotate synchronously by meshing with the gear 44. The slide column 45 drives the air guide pipe 21 to swing back and forth by sliding with the movable swing plate 46 and rotating with the processing box 1. The air guide pipe 21 drives the air outlet 22 to swing synchronously. With the setting of the air guide plate 13, the gas out of the air outlet 22 can be guided to avoid the gas being directly blown into the exhaust pipe 3.

[0055] The exhaust pipe 3 adsorbs dust particles in the intake gas by driving the wave-shaped electrode plate 52 to rotate synchronously, and the purified gas is discharged through the filter hole 31.

[0056] The exhaust pipe 3 drives the lifting seat 62 to rotate synchronously by connecting it to the guide column 63 and by sliding the guide column 63 to the lifting seat 62. The lifting seat 62 achieves reciprocating lifting by sliding the sliding column 621 to the guide ring groove 611 and by connecting the fixed sleeve 61 to the inner wall of the treatment box 1. The lifting seat 62 drives the cleaning brush 65 to reciprocate synchronously by connecting it to the upright 64. The cleaning brush 65 cleans the dust adhering to the outer wall of the electrode plate 52 by contacting the outer wall of the electrode plate 52. In addition, an arc-shaped brush can be connected between the cleaning brushes 65 on both sides of the filter hole 31. The cleaning brush 65 cleans the filter hole 31 by driving the arc-shaped brush to rise and fall synchronously, so as to avoid dust accumulation at the filter hole 31 and facilitate the exhaust of purified gas.

[0057] After being cleaned by the cleaning component 6, the dust falls into the collection pipe 11 and moves along the surface of the conical surface 711 and the groove 712 to the space between the flattening groove 713 and the chassis 82. The motor 41 drives the gear 42 to rotate. The gear 42 rotates the exhaust pipe 3 by meshing with the gear ring 43. The exhaust pipe 3 rotates the guide column 63 and the flattening plate 71 by sliding contact between the guide column 63 and the flattening plate 71. The flattening plate 71 flattens the dust that falls between the flattening groove 713 and the chassis 82. When the dust fills the flattening groove... After the space between 713 and chassis 82 is cleared, the dust will push the flattening disc 71 to slide along the guide post 63 away from chassis 82. The spring 73 will be stressed and contract. At the same time, the flattening disc 71 will continue to rotate and continuously flatten the dust that falls into the flattening groove 713 and chassis 82. After flattening for a period of time, the operator will rotate chassis 82 to release the closure at the bottom of collection pipe 11, so that the flattened dust can be discharged. Then, chassis 82 will be rotated back to reclose the bottom of collection pipe 11, thereby flattening the subsequent dust.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
