Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a dust removal device for cement production. Background Technology

[0002] The entire cement production process (including raw material crushing, raw meal grinding, clinker calcination, cement grinding, and finished product packaging) generates a large amount of dust. If not effectively controlled, it will not only seriously pollute the environment and violate national environmental protection standards, but also endanger the health of operators and affect production efficiency.

[0003] For example, a dust removal device for cement production, as disclosed in announcement number CN215232811U, includes: a working component for dust removal, which is also used to install a dust removal mounting component and a reverse dust removal component; a dust removal mounting component for dust removal in cement production; and a reverse dust removal component for dust removal inside the dust removal device. When a layer of cement dust adheres to the surface of the dust collector bag, the handle is held and pressed to disengage the sealing plug from the bottom of the pipe. After disengagement, the handle is rotated to move the sealing plug in the groove. At this time, the valve of the air outlet pipe is closed, and the blower operates, generating gas at the top of the housing that blows the dust collector bag in the reverse direction through the through-hole. This causes all the cement dust adhering to the surface of the dust collector bag to fall into the collection groove, thus cleaning the dust on the surface of the dust collector bag and ensuring that the dust collector bag can efficiently filter cement dust.

[0004] Because cement dust is hygroscopic, it can absorb water vapor from the air through surface adsorption and capillary action, especially in high-humidity environments. When the damp cement dust passes through the filter bag, it is more likely to clump and adhere to the bag. The damp, clumped dust is difficult to clean off the bag, causing the filtration and air permeability of the bag to decrease after a period of dust removal operation, thus affecting the dust removal efficiency of the equipment. The existing method of using a vibrating impact plate to strike the bag is ineffective because the bag is a flexible structure. Striking from a single point is not enough to clean the entire surface of the bag, and the impact does not completely break up the clumps of dust, resulting in low cleaning efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal device for cement production, so as to solve the problem that cement dust easily clumps and clogs the filter bags after absorbing water and becoming damp, making it difficult to clean and affecting the dust removal efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust removal device for cement production, comprising a dust removal box and support legs fixedly installed at the bottom of the dust removal box, wherein a slag discharge pipe is fixedly installed in the middle of the bottom of the dust removal box; An air inlet pipe is fixedly connected to the upper part of one side of the dust collector, and an air outlet pipe is fixedly connected to the upper part of the other side of the dust collector. An auxiliary dust removal component is installed inside the dust collector, and a pretreatment component is installed inside the air inlet pipe. A partition is horizontally fixedly connected to the upper part of the dust collection box. The auxiliary dust collection component includes a servo motor fixedly installed on the top of the dust collection box. The output end of the servo motor is fixedly connected to a rotating shaft. The rotating shaft passes through the partition and is rotatably connected to an upper sleeve. A lower sleeve is slidably installed on the outer side of the upper sleeve. An outer ring is fixedly connected to the outer side of the lower sleeve. An inner ring is symmetrically rotatably installed on the inner side of the outer ring. A driven bar is fixedly connected to the outer side of the inner ring. A heating coil is fixedly installed on the top of the inner ring.

[0007] Preferably, an air inlet groove is provided on one side of the inner side of the partition, an upper baffle is fixedly connected to the top of the partition near the air inlet pipe, filter bags are symmetrically fixedly installed at the bottom of the partition, and at least three filter bags are provided. An air blowing cleaning mechanism is fixedly installed on the inner top surface of the dust collector. The rotating shaft is rotatably connected to the partition, a push bar is fixedly connected to the lower outer side of the rotating shaft, the upper sleeve is located inside the push bar, an electric push rod is fixedly installed on the inner bottom surface of the lower sleeve, and the telescopic end of the electric push rod is fixedly connected to the inner top surface of the upper sleeve.

[0008] By adopting the above technical solution, the heating coil dries the damp and clump-like dust. The striking tip at the bottom of the inner ring will vibrate and strike autonomously as the inner ring rises, which makes it easier to break up the damp and clump-like dust. The degree of breakage of the clump-like dust is higher, making it easier to quickly peel the clump-like dust off the surface of the filter bag.

[0009] Preferably, the outer side of the upper sleeve is symmetrically and fixedly connected with a limiting strip, the inner side of the lower sleeve is provided with a limiting groove, the limiting strip is slidably connected to the limiting groove, the lower sleeve and the outer sleeve are fixedly connected with a diagonal rod, the outer side of the outer sleeve is symmetrically and fixedly connected with two side rods, the inner wall of the dust collector is symmetrically provided with vertical grooves on both sides, the side rods are slidably connected to the vertical grooves, and the outer side of the inner sleeve is fixedly connected with a driven strip.

[0010] By adopting the above technical solution, the side rod slides inside the vertical groove, so that the outer sleeve, lower sleeve and upper sleeve will not rotate, which facilitates the subsequent retraction of the electric push rod to drive the lower sleeve to rise.

[0011] Preferably, the push bar and the driven bar are spaced apart, an outer ring body is symmetrically fixedly connected to the inner side of the outer ring, a rotating ring is rotatably connected to the inner side of the outer ring body, the inner ring is fixedly connected to the rotating ring, a push inclined block is fixedly connected to one side of the bottom of the rotating ring, and a fixing block is symmetrically fixedly connected to the inner side of the outer ring.

[0012] By adopting the above technical solution, when the outer ring drives the rotating ring, heating ring and fixing ring to rise, the inner ring scrapes off the thick dust on the outside of the filter bag.

[0013] Preferably, the number of filter bags, inner rings, and fixing blocks are all the same. A fixing ring is fixedly connected to one side of the fixing block. A sliding rod is symmetrically slidably installed on the outer ring of the fixing ring. A round block is fixedly connected to one end of the sliding rod. The round block is located in the inner cavity of the fixing ring and is slidably connected to the fixing ring.

[0014] By adopting the above technical solution, the rotating ring drives the inclined block to rotate. When the inclined block rotates to the position of the slide rod, it will squeeze and push the slide rod to move. The slide rod drives the round block and the striking tip to move.

[0015] Preferably, a striking tip is fixedly connected to the side of the circular block away from the slide bar, a spring is sleeved on the outside of the striking tip, one end of the spring is fixedly connected to the inner wall of the fixing ring, and the other end of the spring is fixedly connected to the circular block.

[0016] By adopting the above technical solution, when the inclined block is pushed to separate from the slide bar, the elastic force of the spring drives the striking tip and the slide bar to slide back to their original positions, so that the striking tip strikes the clumps of dust on the outside of the filter bag.

[0017] Preferably, the pretreatment component includes an upper filter plate vertically fixedly installed inside the intake pipe, a hydraulic rod fixedly installed at the top of the intake pipe, a pressing plate fixedly connected to the telescopic end of the hydraulic rod passing through the intake pipe, a baffle plate fixedly connected to the side of the pressing plate away from the upper filter plate, and the baffle plate being slidably connected to the intake pipe.

[0018] By adopting the above technical solution, the gas containing cement dust entering the intake pipe is first filtered by the upper filter plate, and large particles of debris are trapped.

[0019] Preferably, a collection box is fixedly installed at the bottom of the air intake pipe, an inclined filter plate is fixedly connected to the lower part of the inside of the collection box, a horizontal shaft is rotatably connected to the top side of the collection box, and a sealing plate is fixedly connected to the outside of the horizontal shaft.

[0020] By adopting the above technical solution, when too much debris accumulates, the hydraulic rod drives the extrusion plate and the baffle plate to descend. The baffle plate blocks the upper part, reducing the amount of debris falling on the top of the extrusion plate. The extrusion plate pushes the debris down, and the debris squeezes open the sealing plate.

[0021] Preferably, a torsion spring is also sleeved on the outside of the horizontal shaft. One end of the torsion spring is fixedly connected to the collection box, and the other end of the torsion spring is fixedly connected to the sealing plate. A branch pipe is also fixedly connected between the collection box and the air inlet pipe.

[0022] By adopting the above technical solution, the debris enters the collection box, and the gas containing cement dust is filtered by the inclined filter plate and enters the dust collection box from the branch pipe without blocking the incoming gas.

[0023] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting up auxiliary dust removal components, and utilizing the cooperation of servo motors, outer rings, and inner rings, the outer ring and heating ring can be driven to rise during filter bag cleaning, while maintaining uniform rotation of the heating ring. This reduces drying dead zones and facilitates the drying of damp, clump-like dust. The inner ring scrapes away thick dust on the outside of the filter bag, and the striking tip at the bottom of the inner ring vibrates autonomously as the inner ring rises, thus breaking up the damp, clump-like dust. Compared with ordinary striking, there are more striking points, and the degree of dust fragmentation is higher, which helps to reduce the adhesion strength between the dust clumps and the filter bag, making it easier to quickly peel the dust clumps off the filter bag surface. Compared with existing methods of directly blowing air to clean filter bags, this invention is more suitable for cleaning large areas of damp, clump-like dust, reduces cleaning dead zones, avoids incomplete air blowing cleaning, and improves cleaning efficiency and the air permeability and filtration effect of the filter bag. Specific details are as follows: 1. By setting up auxiliary dust removal components, external gas containing cement dust enters the dust collection box through the inlet pipe and inlet slot, is filtered by the filter bags, and then discharged through the outlet pipe. The air blowing cleaning mechanism can clean the filter bags by blowing air. Cement dust will absorb water vapor in the air and clump on the outside of the filter bags. When it is necessary to clean the dust attached to the outside of the filter bags, the servo motor and electric push rod are activated. At the same time, the heating coil is energized and heats up. The servo motor drives the rotating shaft and push bar to rotate. The upper sleeve is rotatably connected to the rotating shaft, and the side rod slides inside the vertical groove, so that the outer sleeve, lower sleeve and upper sleeve do not rotate. The electric push rod retracts and drives the lower sleeve to rise. The limit bar slides inside the limit groove, so that the lower sleeve drives the outer sleeve to rise through the inclined rod. The outer sleeve drives the rotating ring, heating ring and fixed ring to rise. The inner ring scrapes away the thick dust on the outside of the filter bag. The rotation of the push bar causes the driven bar to rotate counterclockwise. The driven bar drives the inner ring, heating ring, and outer ring to rotate. The heating ring heats the outside of the filter bag evenly. The rotating ring drives the push block to rotate. When the push block rotates to the position of the slide bar, it will squeeze and push the slide bar to move. The slide bar drives the round block and the striking tip to move. The round block stretches the spring. When the push block separates from the slide bar, the spring force causes the striking tip and the slide bar to slide back to their original positions. At this time, the striking tip strikes the clumps of dust on the outside of the filter bag, which makes it easier to break up the damp clumps of dust. Compared with ordinary tapping treatment, there are more tapping points and the degree of breakage of clumps of dust is higher, which makes it easier to reduce the adhesion strength of clumps of dust to the filter bag and make it easier to quickly peel off the clumps of dust from the surface of the filter bag. 2. By setting up a pretreatment component, the gas containing cement dust entering the intake pipe first passes through the upper filter plate for filtration, and large particles are trapped. When too much debris accumulates, the hydraulic rod is activated, which drives the extrusion plate and the baffle plate to descend. The baffle plate blocks the upper part, reducing the amount of debris falling on the top of the extrusion plate. The extrusion plate pushes the debris down, and the debris squeezes open the sealing plate. The sealing plate drives the horizontal shaft to rotate, and the horizontal shaft acts on the torsion spring on the outside, allowing the debris to enter the collection box. At this time, the gas containing cement dust passes through the inclined filter plate for filtration and enters the dust collector box from the branch pipe without blocking the incoming gas. The debris falls into the collection box. When the debris accumulation on the outside of the upper filter plate is small, the hydraulic rod drives the extrusion plate to rise and reset. The elasticity of the torsion spring drives the horizontal shaft and the sealing plate to rotate, causing the sealing plate to seal again, preventing large particles from entering the subsequent treatment equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 4 The present invention provides a technical solution: a dust removal device for cement production, including a dust removal box 1 and a support leg 2 fixedly installed at the bottom of the dust removal box 1. A slag discharge pipe 3 is fixedly installed in the middle of the bottom of the dust removal box 1, and a shut-off valve is installed on the outside of the slag discharge pipe 3 to facilitate the collection of dust discharged from subsequent filtration.

[0028] An air inlet pipe 4 is fixedly connected to the upper side of the dust collector 1, and an auxiliary dust removal component 5 is installed inside the dust collector 1.

[0029] A partition 7 is horizontally fixedly connected to the upper part of the dust collector 1. An air inlet groove 8 is opened on one side of the interior of the partition 7. An upper baffle 9 is fixedly connected to the top of the partition 7 near the air inlet pipe 4. Filter bags 11 are symmetrically fixedly installed at the bottom of the partition 7. There are no fewer than three filter bags 11. An air outlet pipe 10 is fixedly connected to the upper part of the other side of the dust collector 1. An air blowing cleaning mechanism 12 is fixedly installed on the inner top surface of the dust collector 1. The air inlet groove 8 and the upper baffle 9 are used to guide the dust-laden gas. The air outlet pipe 10 is used to discharge the filtered gas. The air blowing cleaning mechanism 12 facilitates back-blowing cleaning of the filter bags 11.

[0030] like Figure 1 and Figure 5 - Figure 12As shown, the auxiliary dust removal component 5 includes a servo motor 51 fixedly installed on the top of the dust removal box 1. The output end of the servo motor 51 is fixedly connected to a rotating shaft 52. The rotating shaft 52 passes through the partition 7 and is rotatably connected to an upper sleeve 53. A lower sleeve 55 is slidably installed on the outside of the upper sleeve 53. An outer sleeve ring 59 is fixedly connected to the outside of the lower sleeve 55.

[0031] The rotating shaft 52 is rotatably connected to the partition plate 7. A push bar 512 is fixedly connected to the lower outer side of the rotating shaft 52. The upper sleeve 53 is located inside the push bar 512. Limiting bars 54 are symmetrically fixedly connected to the outer side of the upper sleeve 53. An electric push rod 56 is fixedly installed on the inner bottom surface of the lower sleeve 55. The telescopic end of the electric push rod 56 is fixedly connected to the inner top surface of the upper sleeve 53.

[0032] A limiting groove 57 is provided on the inner side of the lower sleeve 55, and a limiting strip 54 is slidably connected to the limiting groove 57 to maintain the synchronous state of the lower sleeve 55 and the upper sleeve 53. A diagonal rod 58 is fixedly connected between the lower sleeve 55 and the outer sleeve 59. Two side rods 510 are symmetrically fixedly connected to the outer side of the outer sleeve 59. Vertical grooves 511 are symmetrically provided on both sides of the inner wall of the dust collector 1. The side rods 510 are slidably connected to the vertical grooves 511 so that the lower sleeve 55 and the upper sleeve 53 will not rotate. An inner sleeve 516 is symmetrically rotatably installed on the inner side of the outer sleeve 59. A driven strip 518 is fixedly connected to the outer side of the inner sleeve 516. A heating ring 517 is fixedly installed on the top of the inner sleeve 516. The heating ring 517 adopts the existing electric heating rod, model EHEIM.

[0033] The push bar 512 and the driven bar 518 are spaced apart. The outer ring body 513 is symmetrically fixedly connected to the inner side of the outer ring 59. The rotating ring 514 is rotatably connected to the inner side of the outer ring body 513. The inner ring 516 is fixedly connected to the rotating ring 514. The push inclined block 515 is fixedly connected to one side of the bottom of the rotating ring 514. The fixing block 519 is symmetrically fixedly connected to the inner side of the outer ring 59.

[0034] The number of filter bags 11, inner rings 516 and fixing blocks 519 are all the same. A fixing ring 520 is fixedly connected to one side of the fixing block 519. A slide rod 521 is symmetrically slidably installed on the outer ring of the fixing ring 520. A round block 522 is fixedly connected to one end of the slide rod 521. The round block 522 is located in the inner cavity of the fixing ring 520 and is slidably connected to the fixing ring 520.

[0035] A striking tip 523 is fixedly connected to the side of the round block 522 away from the slide bar 521. A spring 524 is sleeved on the outside of the striking tip 523. One end of the spring 524 is fixedly connected to the inner wall of the fixing ring 520, and the other end of the spring 524 is fixedly connected to the round block 522. The multiple symmetrically arranged striking tips 523 expand the striking points and the uniformity of crushing, making it easier to peel off and clean the clumps of dust on the outside of the filter bag 11.

[0036] Example 1: As Figure 5 - Figure 12 As shown, external cement dust enters the dust collector 1 through the air inlet pipe 4 and the air inlet slot 8, is filtered by the filter bag 11, and is discharged through the air outlet pipe 10. The air blowing cleaning mechanism 12 can blow air to clean the filter bag 11. The cement dust will adsorb water vapor in the air and clump on the outside of the filter bag 11.

[0037] When it is necessary to clean the dust attached to the outside of the filter bag 11, the servo motor 51 and the electric push rod 56 are started to work. At the same time, the heating coil 517 is energized and heated. The servo motor 51 drives the rotating shaft 52 and the push bar 512 to rotate. The upper sleeve 53 is rotatably connected to the rotating shaft 52, and the side rod 510 slides inside the vertical groove 511, so that the outer sleeve 59, the lower sleeve 55 and the upper sleeve 53 do not rotate. The electric push rod 56 retracts and drives the lower sleeve 55 to rise.

[0038] The limiting strip 54 slides inside the limiting groove 57, causing the lower sleeve 55 to drive the outer ring 59 to rise via the inclined rod 58. The outer ring 59 drives the rotating ring 514, heating ring 517, and fixing ring 520 to rise. The inner ring 516 scrapes away the thick dust on the outside of the filter bag 11. The rotation of the pushing strip 512 will drive the driven strip 518 to rotate counterclockwise. The driven strip 518 drives the inner ring 516, heating ring 517, and outer ring body 513 to rotate. The heating ring 517 rotates and heats the outside of the filter bag 11 evenly, which facilitates the drying of damp and clumped dust. The rotating ring 514 drives the pushing inclined block 515 to rotate.

[0039] When the inclined block 515 is rotated to the position of the slide bar 521, it will squeeze and push the slide bar 521 to move. The slide bar 521 drives the round block 522 and the striking tip 523 to move. The round block 522 stretches the spring 524. When the inclined block 515 is pushed to separate from the slide bar 521, the elastic force of the spring 524 drives the striking tip 523 and the slide bar 521 to slide back to their original positions. At this time, the striking tip 523 strikes the clumps of dust on the outside of the filter bag 11, which makes it easier to break up the damp clumps of dust. Compared with ordinary tapping treatment, there are more tapping points and the degree of breaking up of clumps of dust is higher, which makes it easier to reduce the adhesion strength of clumps of dust to the filter bag 11 and make it easier to quickly peel off the clumps of dust from the surface of the filter bag 11.

[0040] like Figure 1 and Figure 13 - Figure 14As shown, a pretreatment component 6 is provided inside the intake pipe 4. The pretreatment component 6 includes an upper filter plate 61 that is vertically fixed inside the intake pipe 4. A hydraulic rod 62 is fixedly installed on the top of the intake pipe 4. The telescopic end of the hydraulic rod 62 passes through the intake pipe 4 and is fixedly connected to a squeezing plate 63. A baffle plate 64 is fixedly connected to the side of the squeezing plate 63 away from the upper filter plate 61. The baffle plate 64 is slidably connected to the intake pipe 4. The baffle plate 64 blocks the upper part to reduce debris falling on the top of the squeezing plate 63.

[0041] A collection box 66 is fixedly installed at the bottom of the intake pipe 4. An inclined filter plate 65 is fixedly connected to the lower part of the inside of the collection box 66. A horizontal shaft 67 is rotatably connected to the top side of the collection box 66. A sealing plate 68 is fixedly connected to the outside of the horizontal shaft 67.

[0042] A torsion spring is also sleeved on the outside of the horizontal shaft 67. One end of the torsion spring is fixedly connected to the collection box 66, and the other end of the torsion spring is fixedly connected to the sealing plate 68. A branch pipe 69 is also fixedly connected between the collection box 66 and the air inlet pipe 4. The inclined filter plate 65 filters the gas entering the branch pipe 69.

[0043] Example 2: Figure 13 - Figure 14 As shown, the gas containing cement dust entering the intake pipe 4 is first filtered by the upper filter plate 61, and large particles of debris are trapped. When too much debris accumulates, the hydraulic rod 62 is activated. The hydraulic rod 62 drives the extrusion plate 63 and the baffle plate 64 to descend. The extrusion plate 63 pushes the debris down, and the debris squeezes open the sealing plate 68. The sealing plate 68 drives the horizontal shaft 67 to rotate. The horizontal shaft 67 acts on the torsion spring on the outside, so that the debris enters the collection box 66.

[0044] At this time, the gas containing cement dust is filtered by the inclined filter plate 65 and enters the dust collector 1 through the branch pipe 69. It will not block the incoming gas. The debris falls into the collection box 66. When the debris on the outside of the upper filter plate 61 is less, the hydraulic rod 62 drives the squeezing plate 63 to rise and reset. The elastic force of the torsion spring drives the horizontal shaft 67 and the sealing plate 68 to rotate, so that the sealing plate 68 is sealed again, preventing large particles of debris from entering the subsequent processing equipment.

[0045] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, the gas containing cement dust entering the intake pipe 4 first passes through the upper filter plate 61 for filtration, and large particles are trapped. When too much debris accumulates, the hydraulic rod 62 is activated, which drives the squeezing plate 63 and the baffle plate 64 to descend, and the debris enters the collection box 66. At this time, the gas containing cement dust passes through the inclined filter plate 65 for filtration and enters the dust collector box 1 through the branch pipe 69, and is filtered by the filter bag 11. When it is necessary to clean the dust attached to the outside of the filter bag 11, the servo motor 51 and the electric push rod 56 are activated. At the same time, the heating coil 517 is energized and heats up. The rotation of the push bar 512 will drive the driven bar 518 to rotate counterclockwise. The driven bar 518 drives the inner ring 516, the heating coil 517 and the outer ring body 513 to rotate. 517 heats the outer side of the filter bag 11 evenly by rotating. The rotating ring 514 drives the pushing inclined block 515 to rotate. When the pushing inclined block 515 rotates to the position of the slide rod 521, it will squeeze and push the slide rod 521 to move. The slide rod 521 drives the round block 522 and the striking tip 523 to move. The round block 522 stretches the spring 524. When the pushing inclined block 515 separates from the slide rod 521, the elastic force of the spring 524 drives the striking tip 523 and the slide rod 521 to slide back to their original positions. At this time, the striking tip 523 strikes the clumps of dust on the outer side of the filter bag 11, which makes it easier to break up the damp clumps of dust. The degree of breakage of the clumps of dust is higher, which makes it easier to reduce the adhesion strength between the clumps of dust and the filter bag 11, and makes it easier to quickly peel the clumps of dust off the surface of the filter bag 11.
