Description

Technical Field

[0001] This application relates to the technical field of dust collection and treatment, and particularly relates to a limestone dust collection and treatment device. Background Art

[0002] Limestone is widely used in the manufacture of products such as papermaking, rubber, paint, coatings, medicine, cosmetics, feed, sealing, bonding, and polishing. It is the main raw material for manufacturing cement, lime, and calcium carbide, and is an indispensable flux limestone in the metallurgical industry. A large amount of dust is generated during limestone screening, crushing, and pulverization. These solids will cause air pollution and also damage the physical health of operating personnel. To avoid the above disadvantages, dust collection and treatment equipment is usually equipped.

[0003] Existing limestone dust collection and treatment equipment is usually a bag filter. During the dust removal process of the bag filter, the bags will become blocked. The existing solution is to add a vibration mechanism to shake off the dust and lumps blocking the bags. However, the vibration position of the existing vibration mechanism cannot be adjusted, and it is impossible to quickly vibrate and clean the blocked position of the bags, resulting in an unsatisfactory cleaning effect. Secondly, after the bags are used for a long time, they need to be replaced. The existing bags are installed inside the housing, which is not easy to replace and requires shutdown for processing, which is rather cumbersome. Summary of the Invention

[0004] This application proposes a limestone dust collection and treatment device, which has the advantages of adjustable vibration position and bag replacement without shutdown, to solve the problems that the vibration position of the existing vibration mechanism cannot be adjusted, it is impossible to quickly vibrate and clean the blocked position of the bags, and the existing bags are installed inside the housing, which is not easy to replace and requires shutdown for processing, and the operation is rather cumbersome.

[0005] To achieve the above object, this application adopts the following technical solution: A limestone dust collection and treatment device, comprising: a housing, a plurality of support columns are fixedly connected to the bottom of the housing, a flange is fixedly connected to the bottom end of the housing, and a transparent cover plate is movably installed on the front surface of the housing;

[0006] A control motor, the control motor is fixedly installed on the top of the housing, and a small gear is fixedly connected to the output shaft of the control motor;

[0007] An upper connecting plate, a plurality of rectangular plates and a plurality of upper mounting rings are fixedly connected to the lower surface of the upper connecting plate. The lower end of the rectangular plate is fixedly connected to a lower connecting plate, and a plurality of lower mounting rings are fixedly installed on the upper surface of the lower connecting plate. A bag is fixedly installed between the lower mounting ring and the upper mounting ring. The middle of the upper connecting plate is fixedly connected to a rotating ring, and a large gear is fixedly connected to the upper end of the rotating ring;

[0008] A sector plate, which is fixedly connected to the inner wall of the housing;

[0009] A cleaning mechanism, which is arranged inside the housing;

[0010] The above structure can, during operation, remove the transparent cover plate, release the connection between the lower end of the cloth bag and the lower mounting ring, then rotate the permanent magnet, which drives the lower movable rod to rotate a certain angle inside the limiting groove, and then move upward, thereby releasing the installation of the lower movable rod, and then release the connection between the upper end of the cloth bag and the upper mounting ring, so as to remove the old cloth bag.

[0011] Preferably, the cleaning mechanism includes a fixed seat and a plurality of upper fixing rods. The lower end of the fixed seat is fixedly connected with an installation shell. The upper surface of the fixed seat is fixedly installed with a driving motor. The output shaft end of the driving motor is fixedly connected with a threaded rod. The bottom end of the threaded rod is threadedly connected with a sliding block. The front surface of the sliding block is fixedly installed with an electromagnet. The lower surface of the upper fixing rod is fixedly connected with an elastic rope. The bottom end of the elastic rope is fixedly connected with a lower movable rod. Above the lower movable rod is arranged a sealing block. The upper part of the sealing block is fixedly connected with a permanent magnet;

[0012] The above structure can, during operation, attract the permanent magnet by energizing the electromagnet. At the same time, the driving motor works to drive the threaded rod to rotate, so that the sliding block and the electromagnet move upward. Since the electromagnet and the permanent magnet attract each other, the permanent magnet and the sealing block will move upward following the electromagnet. When the electromagnet drives the permanent magnet to rise to an appropriate position, the electromagnet suddenly loses power, and the elastic rope will drive the permanent magnet to swing, so that the sealing block will repeatedly impact the inner wall of the cloth bag, thereby cleaning the limestone dust and lumps blocking the cloth bag.

[0013] Preferably, a plurality of air inlet holes are formed on the upper surface of the upper connecting plate. The air inlet holes are located directly above the upper mounting ring. The upper surface of the upper connecting plate is in contact with the lower surface of the sector plate.

[0014] Preferably, a plurality of discharge holes are formed on the upper surface of the lower connecting plate. The discharge holes are located directly below the lower mounting ring. The lower connecting plate is rotatably connected to the housing.

The above structure can, during operation, control the motor to work, drive the small gear to rotate. The small gear drives the rotating ring to rotate through the meshing large gear. The rotating ring will drive the upper connecting plate, the rectangular plate and the lower connecting plate to rotate.

[0016] Preferably, the output shaft of the drive motor and the upper end of the threaded rod are both rotatably connected to the fixed seat. The threaded rod is rotatably connected to the installation shell. The sealing block and the permanent magnet are both slidably connected to the elastic rope. The sliding block is slidably connected to the installation shell. With the above structure, during operation, the permanent magnet can slide up and down along the elastic rope. When it automatically slides to the lowest end, the sealing block will be located inside the discharge hole.

[0017] Preferably, the fixed seat is fixedly connected to the upper surface of the housing, and the upper fixed rod is fixedly connected to the inner wall of the upper mounting ring.

[0018] Preferably, two symmetrically arranged limiting grooves are formed in the inner wall of the lower mounting ring, and both ends of the lower movable rod are located inside the limiting grooves. With the above structure, during operation, by rotating the permanent magnet, the lower movable rod can be driven to rotate a certain angle inside the limiting groove, and then moved upward to release the installation of the lower movable rod; reverse operation can complete the fixation of the lower movable rod.

[0019] Preferably, a groove is formed at the bottom of the sealing block, and the groove is adapted to the lower movable rod. The sealing block is adapted to the discharge hole. With the above structure, during operation, by rotating the sealing block, the lower movable rod can be driven to rotate. When the sealing block is located at the lowest end, it can prevent the dust-containing gas from being discharged from the bottom end of the housing.

[0020] Preferably, an air inlet pipe is provided on one side of the housing, and the installation shell is in contact with two rectangular plates. With the above structure, during operation, it can prevent the dust-containing gas from entering the front of the installation shell.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. By controlling the motor to work, the small gear is driven to rotate. The small gear drives the rotating ring to rotate through the meshing large gear, and the cloth bag to be replaced is rotated to the front of the installation shell. The transparent cover plate is removed, the connection between the lower end of the cloth bag and the lower mounting ring is released, and then by rotating the permanent magnet, the lower movable rod is driven to rotate a certain angle inside the limiting groove, and then moved upward to release the installation of the lower movable rod. Then the connection between the upper end of the cloth bag and the upper mounting ring is released, so that the old cloth bag can be removed. The elastic rope is inserted into the new cloth bag. First, the upper part of the cloth bag is fixed to the upper mounting ring, then the lower movable rod is installed, and finally the bottom end of the cloth bag is fixed to the lower mounting ring, thus completing the replacement of the cloth bag without stopping the machine, solving the problem that the existing cloth bag is installed inside the housing, is not easy to replace and requires shutdown treatment, which is rather cumbersome.

[0023] 2. In the present invention, when the electromagnet is energized, it attracts the permanent magnet. At the same time, the driving motor operates to drive the threaded rod to rotate, causing the sliding block and the electromagnet to move upward. Since the electromagnet and the permanent magnet attract each other, the permanent magnet and the sealing block will move upward following the electromagnet. When the electromagnet drives the permanent magnet to rise to an appropriate position, the electromagnet suddenly loses power, and the elastic rope will drive the permanent magnet to swing, causing the sealing block to repeatedly strike the inner wall of the cloth bag, thereby cleaning the limestone dust and lumps blocking the cloth bag, thus solving the problem that the vibration position of the vibration mechanism cannot be adjusted, and it is impossible to quickly vibrate and clean the blocked position of the cloth bag, resulting in an unsatisfactory cleaning effect.

[0038] A cleaning mechanism 16 is arranged inside the housing 1;

[0039] Its function is that by operating the control motor 5, the small gear 6 is driven to rotate. The small gear 6 drives the rotating ring 13 to rotate through the engaged large gear 14, rotates the cloth bag 12 to be replaced to the front of the installation shell 162, removes the transparent cover plate 4, releases the connection between the lower end of the cloth bag 12 and the lower mounting ring 11, and then rotates the permanent magnet 1611 to drive the lower movable rod 169 to rotate a certain angle inside the limit groove and then move upward, so as to release the installation of the lower movable rod 169, and then release the connection between the upper end of the cloth bag 12 and the upper mounting ring 9, so as to remove the old cloth bag 12. Thread the elastic cord 168 into the new cloth bag 12, first fix the upper part of the cloth bag 12 to the upper mounting ring 9, then install the lower movable rod 169, and finally fix the bottom end of the cloth bag 12 to the lower mounting ring 11, thus completing the non-stop replacement of the cloth bag 12, and solving the problem that the existing cloth bag is installed inside the housing, is not easy to replace and requires shutdown treatment at the same time, which is rather cumbersome.

[0040] Among them, the cleaning mechanism 16 includes a fixed seat 161 and a plurality of upper fixing rods 167. The lower end of the fixed seat 161 is fixedly connected with an installation shell 162. The upper surface of the fixed seat 161 is fixedly installed with a driving motor 163. The output shaft end of the driving motor 163 is fixedly connected with a threaded rod 164. The bottom end of the threaded rod 164 is threadedly connected with a sliding block 165.

Above the sealing block 1610 is fixedly connected with a permanent magnet 1611;

[0041] Its function is that when the electromagnet 166 is energized to attract the permanent magnet 1611, at the same time, the driving motor 163 works to drive the threaded rod 164 to rotate, so that the sliding block 165 and the electromagnet 166 move upward. Since the electromagnet 166 and the permanent magnet 1611 attract each other, the permanent magnet 1611 and the sealing block 1610 will move upward following the electromagnet 166. When the electromagnet 166 drives the permanent magnet 1611 to rise to an appropriate position, the electromagnet 166 suddenly loses power, and the elastic cord 168 will drive the permanent magnet 1611 to swing, so that the sealing block 1610 will repeatedly impact the inner wall of the cloth bag 12, thereby cleaning the limestone dust and lumps blocking the cloth bag 12, thus solving the problem that the vibration position of the vibration mechanism cannot be adjusted and it is impossible to quickly vibrate and clean the blocked position of the cloth bag.

[0042] Among them, a plurality of air inlet holes are opened on the upper surface of the upper connecting plate 7. The air inlet holes are located directly above the upper mounting ring 9. The upper surface of the upper connecting plate 7 is in contact with the lower surface of the sector plate 15.

[0043] Among them, a plurality of discharge holes are opened on the upper surface of the lower connecting plate 10. The discharge holes are located directly below the lower mounting ring 11. The lower connecting plate 10 is rotatably connected with the housing 1.

[0044] Among them, the large gear 14 meshes with the small gear 6. The rotating ring 13 is rotatably connected with the housing 1. Its function is to control the motor 5 to work, drive the small gear 6 to rotate, and the small gear 6 drives the rotating ring 13 to rotate through the meshing large gear 14. The rotating ring 13 will drive the upper connecting plate 7, the rectangular plate 8, and the lower connecting plate 10 to rotate.

[0045] Among them, the output shaft of the driving motor 163 and the upper end of the threaded rod 164 are both rotatably connected with the fixed seat 161. The threaded rod 164 is rotatably connected with the installation shell 162. The sealing block 1610 and the permanent magnet 1611 are both slidably connected with the elastic cord 168. The sliding block 165 is slidably connected with the installation shell 162. Its function is that the permanent magnet 1611 can slide up and down along the elastic cord 168. When it automatically slides to the lowest end, the sealing block 1610 will be located inside the discharge hole.

[0046] Among them, the fixed seat 161 is fixedly connected to the upper surface of the housing 1, and the upper fixing rod 167 is fixedly connected to the inner wall of the upper mounting ring 9.

[0047] Among them, two symmetrically arranged limiting grooves are provided on the inner wall of the lower mounting ring 11, and both ends of the lower movable rod 169 are located inside the limiting grooves. Its function is that by rotating the permanent magnet 1611, it drives the lower movable rod 169 to rotate a certain angle inside the limiting groove, and then moves upward, thereby releasing the installation of the lower movable rod 169; reverse operation can complete the fixation of the lower movable rod 169.

[0048] Among them, a groove is provided at the bottom of the sealing block 1610, the groove is adapted to the lower movable rod 169, and the sealing block 1610 is adapted to the discharge hole. Its function is that by rotating the sealing block 1610, it drives the lower movable rod 169 to rotate, and when the sealing block 1610 is at the bottommost position, it can prevent the dust-containing gas from being discharged from the bottom end of the housing 1.

[0049] Among them, an air inlet pipe is provided on one side of the housing 1, and the mounting shell 162 is in contact with the two rectangular plates 8. Its function is to prevent the dust-containing gas from entering the front of the mounting shell 162.

[0050] Working principle:

[0051] Connect the flange 3 to the existing sealed storage device, start the existing dust removal fan, supply the dust-containing gas into the interior of the housing 1 through the air inlet pipe, and the dust-containing gas enters the interior of the cloth bag 12 through the air inlet holes of the upper connecting plate 7. At this time, due to the blockage of the sector plate 15, the air inlet below the sector plate 15 will not have dust-containing gas entering. When the dust-containing gas passes through the cloth bag 12, the limestone dust will be filtered inside the cloth bag 12 and finally slowly settle on the upper surface of the sealing block 1610. The clean gas passes through the cloth bag 12 and will be discharged upward from the middle of the rotating ring 13 out of the interior of the housing 1;

[0052] When it is necessary to discharge or there is a blockage of the limestone dust inside a certain cloth bag 12, the control motor 5 is operated to drive the small gear 6 to rotate. The small gear 6 drives the rotating ring 13 to rotate through the engaged large gear 14. The rotating ring 13 will drive the upper connecting plate 7, the rectangular plate 8, and the lower connecting plate 10 to rotate until the cloth bag 12 with discharge or blockage is located directly in front of the installation shell 162. At this time, the permanent magnet 1611 inside the cloth bag 12 is located directly in front of the electromagnet 166, and the rectangular plates 8 on both sides thereof are in contact with the installation shell 162. The electromagnet 166 is energized to attract the permanent magnet 1611. At the same time, the driving motor 163 operates to drive the threaded rod 164 to rotate, so that the sliding block 165 and the electromagnet 166 move upward. Since the electromagnet 166 and the permanent magnet 1611 attract each other, the permanent magnet 1611 and the sealing block 1610 will move upward following the electromagnet 166. During this process, the elastic cord 168 will deform, and part of the limestone dust inside the cloth bag 12 will fall through the discharge holes to the bottom of the housing 1 and finally be discharged through the flange 3 into the existing sealed storage device. When the electromagnet 166 drives the permanent magnet 1611 to rise to an appropriate position, the electromagnet 166 suddenly loses power, and the elastic cord 168 will drive the permanent magnet 1611 to swing. During this process, the sealing block 1610 will repeatedly impact the inner wall of the cloth bag 12, thereby knocking down the limestone dust and lumps blocking the cloth bag 12 and finally discharging them from the housing 1. The limestone dust remaining above the sealing block 1610 and the permanent magnet 1611 will also be discharged due to the swing. The swinging permanent magnet 1611 and the sealing block 1610 will finally slide to the bottom of the elastic cord 168. After repeated swinging impacts after the permanent magnet 1611 and the sealing block 1610 move upward multiple times, the limestone dust and lumps blocking the cloth bag 12 are cleaned up. When cleaning the blockage, the position where the cloth bag 12 is more severely blocked can be observed through the transparent cover plate 4, and then the permanent magnet 1611 is moved to this position, thereby improving the cleaning effect;

[0053] After the cloth bag 12 has been used for a long time, its filtering effect will decrease and it needs to be replaced. By controlling the operation of the motor 5, the small gear 6 is driven to rotate. The small gear 6 drives the rotating ring 13 to rotate through the meshing large gear 14, and the cloth bag 12 to be replaced is rotated to the front of the installation shell 162. Since the sector plate 15 blocks the air inlet hole above this cloth bag 12, no dust-containing gas will enter the interior of this cloth bag 12. Subsequently, the transparent cover plate 4 is removed, the connection between the lower end of the cloth bag 12 and the lower installation ring 11 is released, and then the permanent magnet 1611 is rotated to drive the lower movable rod 169 to rotate a certain angle inside the limiting groove and then move upward, so as to release the installation of the lower movable rod 169. Then the connection between the upper end of the cloth bag 12 and the upper installation ring 9 is released, so as to remove the old cloth bag 12. The elastic cord 168 is inserted into the interior of the new cloth bag 12. First, the upper part of the cloth bag 12 is fixed to the upper installation ring 9, then the lower movable rod 169 is installed, and finally the bottom end of the cloth bag 12 is fixed to the lower installation ring 11, and the transparent cover plate 4 is installed, thus completing the replacement of the cloth bag 12 without stopping the machine.
