Description

Technical Field

[0001] This invention belongs to the technical field of slag powder processing, and more specifically, it relates to a dust suppression device for slag powder processing and its usage method. Background Technology

[0002] In the production of granulated blast furnace slag powder, the slag powder needs to be conveyed to a grinding device for grinding to obtain slag powder of a suitable particle size. During the conveying and grinding process, a significant amount of dust is typically generated, necessitating dust suppression. Dust suppression equipment usually draws air into the device, filters and intercepts the dust and slag powder in the air, and then the cleaned air is discharged and atomized with water for dust suppression. However, existing dust suppression equipment for slag powder processing has the following drawbacks:

[0003] In the existing technology, dust suppression equipment for slag powder processing usually uses a single interceptor to intercept dust. A large amount of dust will adhere to the surface of the interceptor, causing blockage. This may reduce the suction power of the dust suppression equipment, resulting in poor dust suppression and removal effect. The interceptor needs to be replaced and cleaned, which makes operation inconvenient.

[0004] In the existing technology, the dust suppression mechanism of the dust suppression equipment commonly used for slag powder processing uses multiple bolts for fixed connection. Therefore, it is necessary to disassemble and repair the interceptor and tighten multiple bolts during installation, which makes the operation inconvenient. Moreover, the dust suppression equipment for slag powder processing needs to be stopped when replacing the interceptor, thus affecting the dust suppression efficiency of the dust suppression equipment for slag powder processing.

[0005] In the prior art, in order to improve the filtration effect of air, dust suppression equipment for slag powder processing usually requires the use of multiple interceptors to perform multiple filtration and interception of slag powder and dust in the air. However, the degree of impurity adsorption by multiple interceptors at different positions is different, resulting in more impurities adsorbed on the interceptors located at the front. This leads to the frequency of cleaning and replacing several interceptors at the same time, thus affecting the use effect of dust suppression equipment for slag powder processing.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a dust suppression device for slag powder processing and its usage method, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0017] In a further technical solution, an outlet is provided on one side of the processing cavity, a rotating plate is rotatably provided inside the outlet, and a second opening is provided on the side of the cylinder facing the outlet.

[0018] A further technical solution, a method for using a dust suppression device for slag powder processing, includes the following steps:

[0019] S1: Dust extraction and interception. The air in the workshop where slag powder is processed is drawn into the box by a dust extraction fan, which initially reduces dust in the air in the workshop. Then, the air is filtered and intercepted multiple times by the first filter component, the second filter component, and the third filter component, so that the slag powder and dust in the air are intercepted in the filter chamber.

[0020] S2: Clean the interceptors, move the filter chamber to the lower side to connect the filter chamber with the first opening, and clean the three pairs of interceptors in the first filter assembly, second filter assembly, and third filter assembly respectively through the first processing component, the second processing component, and the third processing component. The slag powder and dust in the filter chamber fall into the lower side of the processing chamber through the first opening. Then, the positions of the two interceptors are changed and the two interceptors are flipped so that one side of the two interceptors is always in front, so that the degree of impurities adsorbed on the two interceptors is the same. This is conducive to cleaning or replacing several pairs of interceptors at the same time, extending the service life of several pairs of interceptors, and improving the use effect of the dust suppression equipment for slag powder processing.

[0021] S3: Detection. The air after multiple filtrations enters the air chamber, where a gas detector detects the air. When the gas detector detects that the air in the air chamber is not up to standard, the air is returned to the air intake chamber and filtered again by the first, second, and third filter components in another filter chamber, so that clean air can enter the fog cannon.

[0022] S4: Replace the interceptor components and move the filter chamber to the second opening side. This allows for the unified replacement of the three pairs of interceptor components in the first filter assembly, second filter assembly, and third filter assembly through the outlet and the second opening, thereby maintaining the dust suppression equipment for slag powder processing to filter and intercept slag powder and dust in the air.

[0023] S5: Dust suppression. The gas detector detects the air in the air chamber, allowing clean air to enter the mist cannon along with the solution in the water tank for atomization and spraying to suppress dust, thereby further improving the dust suppression effect of the dust suppression equipment used in slag powder processing.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This invention discloses a dust suppression device for slag powder processing and its usage method. By rotating a cuboid, four filter chambers are sequentially moved to the upper side, allowing the first, second, and third filter components within each chamber to perform multiple filtration and interception functions on the intake air, thus improving the air treatment effect. Furthermore, by sequentially moving the four filter chambers to the second opening side, several pairs of intercepting elements can be replaced in a timely manner. During the replacement of these intercepting elements, the intercepting elements in other filter chambers can continue to perform their normal filtration and interception functions, without affecting the normal operation of the dust suppression device for slag powder processing and maintaining its dust suppression efficiency.

[0026] The dust suppression device for slag powder processing and its usage method of the present invention includes a first processing component, a second processing component, and a third processing component. A moving plate moves upward, causing the first, second, and third processing components to move upward. This upward movement of the moving plate causes an annular plate, a second rotating shaft, and a third circular plate to move upward. The upward movement of the third circular plate causes two pairs of fixed plates to move upward. The upward movement of the two pairs of fixed plates, in conjunction with the rotation of several cleaning components, cleans the two end faces of two intercepting components, facilitating the removal and shedding of impurities adsorbed on the two intercepting components. Thus, the first, second, and third processing components clean the three pairs of intercepting components in the first, second, and third filter components, respectively, which helps maintain the air filtration and interception effect of the three pairs of intercepting components in the first, second, and third filter components. Furthermore, by changing the position of two intercepting components, one end face of each intercepting component is always in the front position, ensuring that each pair of intercepting components is used in the same way. This facilitates uniform replacement of each pair of intercepting components, extends the service life of several pairs of intercepting components, and improves the usage effect of the dust suppression device for slag powder processing.

[0027] The dust suppression device for slag powder processing and its usage method of the present invention includes a first filter assembly, a second filter assembly, and a third filter assembly. The three pairs of intercepting elements in the first, second, and third filter assemblies are respectively a fine hair adsorption plate, a sponge adsorption plate, and an activated carbon adsorption plate, thereby performing multiple filtration and interception of slag powder and dust in the air. This improves the air treatment effect of the dust suppression device for slag powder processing, allowing clean air to enter the mist cannon and be atomized and sprayed out together with the solution for dust suppression. Furthermore, the elastic force generated by the compression of each pair of springs acts on two clamping plates, causing the two clamping plates to move towards each other and compress and fix the intercepting elements, facilitating the rapid replacement of the three pairs of intercepting elements in the first, second, and third filter assemblies.

[0054] Preferably, a method of using a dust suppression device for slag powder processing includes the following steps:

[0055] S1: Dust extraction and interception. The air in the workshop where the slag powder is processed is drawn into the housing 10 by the dust extraction fan 19, thereby performing a preliminary dust reduction effect on the air in the workshop. Then, the air is filtered and intercepted multiple times by the first filter component 34, the second filter component 35, and the third filter component 36, thereby intercepting the slag powder and dust in the air in the filter chamber 70.

[0056] S2: Clean the interceptors. Move the filter chamber 70 to the lower side so that the filter chamber 70 is connected to the first opening 51. The first processing component 37, the second processing component 38, and the third processing component 39 clean the three pairs of interceptors 50 in the first filter component 34, the second filter component 35, and the third filter component 36, respectively. The slag powder and dust in the filter chamber 70 fall into the lower side of the processing chamber 25 through the first opening 51. Then, the positions of the two interceptors 50 are changed, and the two interceptors 50 are flipped so that one side of the two interceptors 50 is always in front. This makes it easier to ensure that the degree of impurities adsorbed on the two interceptors 50 is the same. This is beneficial for cleaning or replacing several pairs of interceptors 50 at the same time, extending the service life of several pairs of interceptors 50, and improving the use effect of the dust suppression equipment for slag powder processing.

[0057] S3: Detection. The air after multiple filtrations enters the air chamber 22, where the air is detected by the gas detector 73. When the gas detector 73 detects that the air in the air chamber 22 is unqualified, the air in the air chamber 22 returns to the air intake chamber 24 and is filtered again by the first filter component 34, the second filter component 35, and the third filter component 36 in another filter chamber 70, so that clean air can enter the fog cannon 15.

[0058] S4: Replace the interceptor components by moving the filter chamber 70 to the side of the second opening 68, thereby uniformly replacing the three pairs of interceptor components 50 in the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36 through the outlet 66 and the second opening 68, so as to maintain the dust suppression equipment for slag powder processing to filter and intercept slag powder and dust in the air.

[0059] S5: Dust suppression. The gas detector 73 detects the air in the air chamber 22 so that clean air and the solution in the water tank 14 can be atomized and sprayed into the mist cannon 15 to suppress dust, thereby further improving the dust suppression effect of the dust suppression equipment for slag powder processing.

[0060] Specific usage of this invention:

[0061] S1: Dust extraction and interception. The control terminal starts the dust extraction fan 19, which draws air from the slag powder processing workshop into the disc 12 for initial dust reduction. The air entering the disc 12 is initially filtered by the filter plate 13. Then, the air in the disc 12 enters the air intake chamber 24 through the air hole 20, and the air in the air intake chamber 24 enters the filter chamber 70 located on the upper side through the air intake hole 31. The air in the filter chamber 70 undergoes multiple filtration and interception through three pairs of interceptors 50 in the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36, thereby intercepting the slag powder and dust in the air within the filter chamber 70. The first filter assembly 34, the second filter assembly 35, and the third filter assembly 36 each contain three pairs of intercepting elements 50: a fine hair adsorption plate, a sponge adsorption plate, and an activated carbon adsorption plate, respectively. These elements provide multiple layers of filtration to intercept slag powder and dust in the air, improving the air treatment capabilities of the dust suppression equipment used in slag powder processing. This allows clean air to enter the mist cannon 15 and be atomized and sprayed out along with the solution for dust suppression. The air, after multiple filtrations, enters the exhaust chamber 26 through the exhaust port 32. Several pairs of springs 47 are compressed, and the elastic force generated by the compression of every two pairs of springs 47 acts on two clamping plates 46, causing the two clamping plates 46 to move towards each other and compress and fix the intercepting elements 50.

[0062] S2: The interceptor is cleared. The control terminal starts the first motor 28, which drives the first rotating shaft 29 and the cuboid 30 to rotate. The rotation of the cuboid 30 causes the four filter chambers 70 to move sequentially to the lower side of the cylinder 27, so that the filter chambers 70 are connected to the first opening 51. At this time, the slag powder and dust in the filter chambers 70 fall into the lower side of the processing chamber 25 through the first opening 51. Then, the control terminal retracts the two first electric telescopic rods 53, causing the moving plate 52 to move upward, which in turn causes the annular plate 55, the second rotating shaft 54 ​​and the third circular plate 56 to move upward. The upward movement of the third circular plate 56 causes the two pairs of fixed plates 58 to move upward. The upward movement of the fixed plates 58 causes several second rotating shafts 60, the cleaning component 59 and the second gear 61 to move upward. The second gear 61 moves upward by meshing with the outer side of one of the second gears 61 and the side of the rack 62. The movement causes one of the second gears 61 to rotate, and then the meshing of two adjacent second gears 61 causes one of the second gears 61 to rotate, thereby causing several second gears 61 to rotate. The rotation of several second gears 61 drives several second rotating shafts 60 and cleaning components 59 to rotate. The two pairs of fixed plates 58 move upward to cooperate with the rotation of several cleaning components 59, thereby cleaning the two end faces of the two intercepting components 50, so that the impurities adsorbed on the two intercepting components 50 can be cleaned and fall off. Thus, the first processing component 37, the second processing component 38, and the third processing component 39 respectively clean the three pairs of intercepting components 50 in the first filter component 34, the second filter component 35, and the third filter component 36, which helps to maintain the air filtration and interception function of the three pairs of intercepting components 50 in the first filter component 34, the second filter component 35, and the third filter component 36. In the initial state, the outer side of the upper second gear 61 meshes with one side of the rack 62. Then, the third circular plate 56 moves upward and drives several second gears 61 to move upward through two pairs of fixed plates 58. This causes the outer sides of several second gears 61 in the same vertical direction to mesh with one side of the rack 62 in sequence. This allows the several second gears 61 to maintain a rotating state while moving upward, so that the interceptor 50 can be quickly cleaned by the rotation of several cleaning parts 59, maintaining the air filtration and interception effect of several pairs of interceptor parts 50.

[0063] Secondly, the control terminal retracts the three second electric telescopic rods 74, thereby moving the three racks 62. Then, the control terminal starts the three second motors 64 in the first processing component 37, the second processing component 38, and the third processing component 39. The starting of the second motors 64 drives the fourth gear 65 to rotate. Through the outer side of the fourth gear 65 meshing with the outer side of the third gear 63, the second rotating shaft 54 ​​and the third circular plate 56 rotate. The rotation of the third circular plate 56 drives the two pairs of fixed plates 58 to revolve. The two pairs of fixed plates 58 revolve and contact the two interceptors 50, thereby driving the first circular plate 40 to rotate. The rotation of the first circular plate 40 drives the first rotating shaft 41 and the second circular plate 42 to rotate. Through the outer side of the rubber ring 43 and the inner side of the cuboid 30, the first circular plate 40 rotates smoothly, so that the two interceptors 50 can change positions back and forth. Simultaneously, the two interceptor components 50 and the two first rotating blocks 44 revolve, driving the two first gears 48 to revolve. The two first gears 48 revolve and are fixed in place by the internal gear ring 49, thereby causing the two first rotating blocks 44 and the two interceptor components 50 to rotate. This allows the two interceptor components 50 to change positions back and forth while ensuring that one end face of each interceptor component 50 is always in the front position. This ensures that each pair of interceptor components 50 is used in the same way, which is beneficial for the unified replacement of each pair of interceptor components 50, extending the service life of several pairs of interceptor components 50 and improving the dust suppression effect of the dust suppression equipment for slag powder processing.

[0064] S3: Detection. Air from the outlet chamber 26 enters the air chamber 22 through the one-way valve 33, and then the air in the air chamber 22 is detected by the gas detector 73. When the gas detector 73 detects that the air quality in the air chamber 22 is qualified, the control terminal controls the first solenoid valve 71 to open and the second solenoid valve 72 to close, so that the air in the air chamber 22 enters the fog cannon 15 through the first solenoid valve 71 and the second telescopic connecting pipe 18. When the gas detector 73 detects that the air quality in the air chamber 22 is unqualified, the control terminal controls the second solenoid valve 72 to open and the first solenoid valve 71 to close, so that the air in the air chamber 22 returns to the inlet chamber 24 through the second solenoid valve 72, and is then re-filtered and intercepted by the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36 in another filter chamber 70, so that clean air can enter the fog cannon 15. The control terminal also prompts the staff to replace the three pairs of interceptors 50 in the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36 in the filter chamber 70 in a timely manner.

[0065] S4: Replace the interceptor components. The control terminal operates the two first electric telescopic rods 53 to extend, causing the moving plate 52 to move downwards. The moving plate 52 moves downwards, causing the first processing component 37, the second processing component 38, and the third processing component 39 to move downwards. Then, the control terminal operates the first motor 28 to start. The first motor 28 starts, causing the first rotating shaft 29 and the cuboid 30 to rotate. The rotation of the cuboid 30 causes the four filter chambers 70 to move sequentially to one side of the second opening 68. The operator flips the rotating plate 67 to open the outlet 66. The operator replaces three pairs of interceptor components 50 in the first filter component 34, the second filter component 35, and the third filter component 36 through the outlet 66 and the second opening 68. This maintains the dust suppression equipment for slag powder processing, which filters and intercepts slag powder and dust in the air. This facilitates the atomization and spraying of clean air and solution for dust suppression, improving the dust suppression effect of the dust suppression equipment for slag powder processing.

[0066] S5: Dust suppression. Air in the air chamber 22 enters the mist cannon 15 through the first solenoid valve 71 and the second telescopic connecting pipe 18, and the solution in the water tank 14 also enters the mist cannon 15 for atomization and spraying to suppress dust, thereby further improving the dust suppression effect of the dust suppression equipment for slag powder processing.

[0067] The present invention discloses a dust suppression device for slag powder processing and its method of use. By rotating a cuboid 30, four filter chambers 70 are moved sequentially to the upper side, allowing the first filter assembly 34, second filter assembly 35, and third filter assembly 36 within the four filter chambers 70 to sequentially perform multiple filtration and interception functions on the intake air, thereby improving the air treatment effect. Furthermore, by sequentially moving the four filter chambers 70 to the side of the second opening 68, several pairs of intercepting elements 50 can be replaced in a timely manner. During the replacement of these pairs of intercepting elements 50, the pairs of intercepting elements 50 in other filter chambers 70 can continue to perform their normal filtration and interception functions, without affecting the normal operation of the dust suppression device for slag powder processing, thus maintaining the dust suppression efficiency of the device.

[0068] The dust suppression device for slag powder processing and its usage method of the present invention are provided with a first filter assembly 34, a second filter assembly 35, and a third filter assembly 36. The three pairs of intercepting elements 50 in the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36 are respectively a fine hair adsorption plate, a sponge adsorption plate, and an activated carbon adsorption plate, thereby performing multiple filtration and interception of slag powder and dust in the air. This improves the air treatment effect of the dust suppression device for slag powder processing, allowing clean air to enter the mist cannon 15 and be atomized and sprayed out together with the solution for dust suppression. Furthermore, the elastic force generated by the compression of each pair of springs 47 acts on two clamping plates 46, causing the two clamping plates 46 to move towards each other and compress and fix the intercepting elements 50, facilitating the rapid replacement of the three pairs of intercepting elements 50 in the first filter assembly 34, the second filter assembly 35, and the third filter assembly 36.

[0069] The dust suppression device for slag powder processing and its usage method of the present invention includes a first processing component 37, a second processing component 38, and a third processing component 39. A moving plate 52 moves upward, causing the first processing component 37, the second processing component 38, and the third processing component 39 to move upward. The upward movement of the moving plate 52 causes the annular plate 55, the second rotating shaft 54, and the third circular plate 56 to move upward. The upward movement of the third circular plate 56 causes two pairs of fixed plates 58 to move upward. The upward movement of the two pairs of fixed plates 58, in conjunction with the rotation of several cleaning components 59, cleans the two end faces of the two intercepting components 50, facilitating the removal and removal of impurities adsorbed on the two intercepting components 50, thereby achieving dust suppression. The first processing component 37, the second processing component 38, and the third processing component 39 clean the three pairs of interceptors 50 in the first filter component 34, the second filter component 35, and the third filter component 36, respectively. This helps maintain the air filtration and interception function of the three pairs of interceptors 50 in the first filter component 34, the second filter component 35, and the third filter component 36. Furthermore, by changing the position of two interceptors 50, one end face of each interceptor 50 is always in the front, so that each pair of interceptors 50 is used in the same way. This facilitates the unified replacement of each pair of interceptors 50, extends the service life of several pairs of interceptors 50, and improves the dust suppression equipment for slag powder processing.

6. A method of using a dust suppression device for slag powder processing, based on the dust suppression device for slag powder processing according to any one of claims 1-5, characterized in that, Includes the following steps: S1: Dust extraction and interception. The air in the workshop where slag powder is processed is drawn into the box by a dust extraction fan, which initially reduces dust in the air in the workshop. Then, the air is filtered and intercepted multiple times by the first filter component, the second filter component, and the third filter component, so that the slag powder and dust in the air are intercepted in the filter chamber. S2: Clean the interceptors, move the filter chamber to the lower side to connect the filter chamber with the first opening, and clean the three pairs of interceptors in the first filter assembly, second filter assembly, and third filter assembly respectively through the first processing component, the second processing component, and the third processing component. The slag powder and dust in the filter chamber fall into the lower side of the processing chamber through the first opening. Then, the positions of the two interceptors are changed and the two interceptors are flipped so that one side of the two interceptors is always in front, so that the degree of impurities adsorbed on the two interceptors is the same. This is conducive to cleaning or replacing several pairs of interceptors at the same time, extending the service life of several pairs of interceptors, and improving the use effect of the dust suppression equipment for slag powder processing. S3: Detection. The air after multiple filtrations enters the air chamber, where a gas detector detects the air.

S4: Replace the interceptor components and move the filter chamber to the second opening side. This allows for the unified replacement of the three pairs of interceptor components in the first filter assembly, second filter assembly, and third filter assembly through the outlet and the second opening, thereby maintaining the dust suppression equipment for slag powder processing to filter and intercept slag powder and dust in the air. S5: Dust suppression. The gas detector detects the air in the air chamber, allowing clean air to enter the mist cannon along with the solution in the water tank for atomization and spraying to suppress dust, thereby further improving the dust suppression effect of the dust suppression equipment used in slag powder processing.
