Description

Technical Field

[0001] This utility model relates to the technical field of rock wool production equipment, specifically to a dust collection device for rock wool production. Background Technology

[0002] Rock wool, an inorganic fiber material made from basalt as its core raw material through high-temperature melting, is widely used in building insulation, industrial insulation, and noise control due to its excellent properties such as light weight, low thermal conductivity, and non-combustibility. It is an indispensable functional material in modern industry and construction. In the industrial production process of rock wool, precise cutting of rock wool boards according to downstream application needs is a key step. However, rock wool fibers are fine and brittle, easily generating a large amount of floating dust and short fiber debris during cutting. If not controlled in time, this can cause multiple problems: First, dust and fibers will permeate the air in the production workshop, and long-term inhalation by operators can easily induce respiratory diseases and endanger occupational health; second, dust adhering to the surfaces of transmission parts and electrical components of production equipment will accelerate equipment wear, interfere with precision control, and even cause malfunctions and shutdowns; at the same time, fugitive dust emissions will also pollute the surrounding environment, failing to meet environmental regulations for industrial dust emission control.

[0003] To address the dust problem during rock wool cutting, the industry has developed various dust removal technologies. The core concept is often negative pressure suction and filtration interception. This involves using a fan to generate negative pressure, drawing dust-laden airflow from the cutting area into a duct, where a filter separates the dust from the air, resulting in clean air discharge. For example, Chinese patent CN219563347U discloses a dust prevention device for rock wool board processing and cutting. This device collects dust-laden airflow through an enclosed ventilation hood, directs it through a second ventilation pipe into a ventilation box, uses a filter mesh plate within the ventilation box to intercept dust, and finally discharges clean air through an exhaust fan, collecting the filtered dust in a collection box.

[0004] However, existing technologies still have significant drawbacks, which restrict the stability and practicality of dust removal effects: First, existing equipment generally adopts a single-stage filtration structure, such as a single filter mesh plate, which can only intercept impurities of a specific particle size. If dust and fibers are mixed, such as large particles and fine fibers coexisting, large particles can easily clog the mesh, and fine fibers can penetrate the filter layer, making it difficult to achieve filtration efficiency. Second, existing equipment lacks a targeted filtration and cleaning mechanism. Negative pressure suction causes dust and fibers to adhere tightly to the surface of the filter structure. As the usage time increases, the filter channels gradually become clogged, leading to increased airflow resistance, decreased negative pressure suction, and ultimately a sharp decline in dust removal effect. To restore performance, frequent manual shutdowns and disassembly of the filter structure are required for cleaning, which not only increases the labor intensity of operators but also interrupts the production process and reduces overall production efficiency. Third, the sealing design of some equipment is not perfect, and dust-laden airflow can easily leak from the gaps in the ventilation hood, pipe interfaces, or filter box, resulting in a reduced dust removal range and dust overflow, making it impossible to achieve full-area dust control. Utility Model Content

[0005] The purpose of this invention is to provide a dust collection device for rock wool production that can simultaneously achieve high-efficiency filtration, automatic anti-clogging, and low maintenance costs, in order to meet the actual needs of industrial production.

[0006] This utility model is achieved through the following technical solution: a dust collection device for rock wool production, comprising: The workbench has a cutting notch on its upper surface and a cutting component for cutting rock wool is connected to its lower end. A dustproof assembly, mounted on a workbench, includes a filter, a cleaning component, a collection pipe, and a fan, wherein: The filter element is fixedly connected to the lower end face of the workbench. The filter element consists of a filter box, a first filter plate, and a second filter plate. The first filter plate and the second filter plate are arranged parallel to each other along the airflow direction and are both fixedly connected to the inside of the filter box. The cleaning component is set to correspond to the filter component. The cleaning component consists of a telescopic device, a first cleaning component, and a second cleaning component. The first cleaning component and the second cleaning component are arranged in parallel and spaced apart, and are both fixed to the telescopic end of the telescopic device. The telescopic device is fixedly connected to the lower end face of the workbench and located on one side of the cutting notch. One end of the collection pipe is sealed to the air outlet of the filter box, and the other end of the collection pipe is sealed to the air inlet of the fan. When the dustproof component is in use, the telescopic end of the telescopic device extends and retracts in the vertical direction, driving the first cleaning component and the second cleaning component to enter and exit the filter box, respectively cleaning the first filter plate and the second filter plate.

[0007] The working principle of this technical solution is as follows: after the fan starts, negative pressure is generated in the filter box through the collection pipe, which drives the dust-laden airflow in the cutting area of ​​the workbench to flow along a preset path to achieve directional dust collection; the first filter plate and the second filter plate are set parallel and spaced along the airflow direction, and the pore size or material can be designed differently according to the characteristics of rock wool cutting impurities. When the airflow passes through the two-stage filter plates in sequence, the impurities are intercepted in layers, improving the dust removal efficiency; the telescopic device drives the first and second cleaning components to enter and exit the filter box simultaneously through the linear movement of the telescopic end, so as to achieve targeted cleaning of the two-stage filter plates.

[0008] To better realize this utility model, the dustproof component further includes a protective cover, which is fixedly connected to the upper surface of the workbench and covers the outside of the cutting component. The top of the protective cover has an air outlet, which is sealed to the end of the collection pipe away from the filter box.

[0009] To better realize this utility model, the filter box is further composed of a box body and a sealing plate, wherein: The box body is a hollow structure with an open top. The top edge of the box body is sealed and fixedly connected to the lower end face of the workbench. The first filter plate and the second filter plate are both vertically fixed inside the box body. The size of the sealing plate is adapted to the size of the top opening of the box. The sealing plate is fixedly connected to the telescopic end of the telescopic device. The first cleaning component and the second cleaning component are both fixed to the side of the sealing plate facing the inside of the box. When the telescopic end of the telescopic device extends, the sealing plate can fit against the edge of the top opening of the box, thus sealing the filter box.

[0010] To better realize this utility model, a sealing gasket is fixedly connected to the edge of the box near the top opening. The sealing gasket is made of rubber and is used to enhance the sealing performance when the sealing plate is attached to the box, preventing dust from spreading from the gap between the two.

[0011] To better realize this utility model, the first cleaning component further comprises a fixing frame and a cleaning brush, wherein: The fixing frame has an inverted U-shaped structure. The top of the fixing frame is fixedly connected to the side of the sealing plate facing the box, and the opening direction of the fixing frame is consistent with the thickness direction of the first filter plate. The cleaning brush is detachably connected to the inner wall of the fixing frame by a buckle or bolt. The length of the bristles of the cleaning brush is adapted to the thickness of the first filter plate. When the first cleaning component enters the filter box, the bristles can contact and scrape the two sides of the first filter plate.

[0012] To better realize this utility model, the second cleaning component further comprises a mounting bracket, a diverter pipe, a nozzle, and a connecting pipe, wherein: The mounting bracket is long and narrow, with one end fixedly connected to the side of the sealing plate facing the housing, and the length direction of the mounting bracket is parallel to the length direction of the second filter plate. The diversion pipe is horizontally fixed to the side of the mounting bracket away from the sealing plate, with one end of the diversion pipe closed and the other end sealed to one end of the connecting pipe; The nozzle is provided in multiple ways, and the multiple nozzles are evenly spaced along the length direction of the flow divider. The other end of the connecting pipe extends out of the filter box and is used for a sealed connection with an external high-pressure gas source device.

[0013] To better realize this utility model, the air outlet of the nozzle is further directed toward the surface of the second filter plate, and the axis of the nozzle forms an angle of 30° to 60° with the surface of the second filter plate.

[0014] To better realize this utility model, the cutting component further includes: The drive device is a servo motor, which is fixedly connected to the outer wall of the protective cover. The output end of the drive device is fixedly connected to one end of the output shaft through a coupling, and the other end of the output shaft is rotatably connected to the inner wall of the protective cover through a deep groove ball bearing. The cutting blade is fixedly connected to the middle of the output shaft by a flat key, and the cutting edge of the cutting blade extends into the cutting notch, and the rotation trajectory of the cutting edge does not exceed the upper surface of the worktable.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: (1) This utility model constructs a multi-stage interception system by arranging the first filter plate and the second filter plate in parallel in the filter box. The pore size and material of the first and second filter plates can be differentiated according to the characteristics of impurities generated by rock wool cutting. When the dust-laden airflow passes through the two-stage filter plates in sequence, impurities of different particle sizes and shapes are intercepted in layers. Compared with the existing single-stage filtration structure, the dust removal efficiency is improved, and it can adapt to rock wool cutting scenarios of different thicknesses and densities, ensuring that the discharged air meets the workshop air quality standards. (2) This utility model provides a combined cleaning solution by adding a first cleaning component and a second cleaning component, and drives the cleaning component in and out of the filter box by a telescopic device: For large particles of debris attached to the first filter plate, the cleaning brush scrapes them with the bristles to prevent the debris from getting stuck in the mesh; For fine fibers adsorbed on the second filter plate, high-pressure gas forms a uniform airflow through the diverter and nozzle to achieve cleaning without dead angles; The cleaning process can be automatically triggered by a timer controller or pressure sensor without stopping the machine for manual intervention, ensuring that the filter structure remains unobstructed for a long time, the airflow resistance is stable, and the dust removal effect is reduced due to blockage, thus extending the continuous operation time of the equipment; (3) In this utility model, the filter box body is sealed to the lower end face of the workbench, the sealing plate is attached to the top opening of the box body by a rubber sealing gasket, and the interface between the collection pipe and the filter box and the fan is sealed to prevent dust from overflowing into the workshop environment from the gaps. This not only protects the occupational health of the operators, but also reduces the pollution to the surrounding environment. (4) In this utility model, the cleaning brush of the first cleaning component is connected to the fixed frame by a buckle or bolt. When the brush bristles are worn, the cleaning brush can be disassembled and replaced separately without replacing the entire cleaning component, thus reducing maintenance costs. The diversion pipe and nozzle of the second cleaning component are independent components. If the nozzle is blocked, it can be disassembled and cleared or replaced separately, making operation convenient. The bottom of the filter box can be equipped with a drawer-type collection box. The impurities after cleaning fall directly into the collection box, and the filter box can be cleaned without disassembling it, further reducing maintenance time. In addition, the telescopic device and the drive device are all standardized components, which are convenient to purchase and replace, reducing the maintenance cost of the entire equipment life cycle. (5) In this utility model, the protective cover not only covers the cutting blade to reduce the dust diffusion range, but also serves as the airflow inlet of the collection pipe to ensure that the dust-laden airflow is efficiently sucked in; the rotation trajectory of the cutting blade does not exceed the workbench surface to avoid the blade being exposed and scratching the operator during cutting; the drive device adopts a servo motor, which can accurately control the cutting speed and blade rotation speed, and with stable negative pressure dust removal, it reduces the cutting deviation caused by dust adhesion, improves the cutting accuracy and product qualification rate, and the overall structure is compact, without the need to occupy additional workshop space, realizing the collaborative operation of cutting and dust removal, and improving the continuity and safety of the production process; (6) This utility model effectively overcomes the problems of low filtration efficiency, easy clogging, difficult maintenance and dust leakage of existing rock wool cutting dust removal equipment. While improving the dust removal effect and environmental protection, it reduces the production and maintenance costs. It has significant practical value and industrialization prospects and is suitable for widespread application. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0021] The main structure of this embodiment is as follows: Figures 1-5 As shown, it includes: Workbench 1, the upper surface of which is provided with a cutting notch 2, and the lower end face of the workbench 1 is connected to a cutting component for cutting rock wool; Dustproof assembly, assembled on workbench 1, includes filter element 3, cleaning element 4, collection pipe 5, and fan 6, wherein: The filter element 3 is fixedly connected to the lower end face of the workbench 1. The filter element 3 consists of a filter box 7, a first filter plate 8, and a second filter plate 9. The first filter plate 8 and the second filter plate 9 are arranged parallel to each other along the airflow direction and are both fixedly connected to the inside of the filter box 7. The cleaning component 4 is set in relation to the filter component 3. The cleaning component 4 is composed of a telescopic device 10, a first cleaning component 11 and a second cleaning component 12. The first cleaning component 11 and the second cleaning component 12 are arranged in parallel and spaced apart and are both fixed to the telescopic end of the telescopic device 10. The telescopic device 10 is fixedly connected to the lower end face of the workbench 1 and is located on one side of the cutting notch 2. One end of the collection pipe 5 is sealed to the air outlet of the filter box 7, and the other end of the collection pipe 5 is sealed to the air inlet of the fan 6. When the dustproof component is in use, the telescopic end of the telescopic device 10 extends and retracts in the vertical direction, driving the first cleaning component 11 and the second cleaning component 12 to enter and exit the filter box 7, respectively cleaning the first filter plate 8 and the second filter plate 9.

[0022] The specific implementation process is as follows: Place the rock wool board to be cut on the upper surface of the workbench 1, ensuring that the cutting path of the rock wool board is aligned with the cutting notch 2; check the status of the filter 3, cleaning component 4, and collection pipe 5; start the cutting assembly and fan 6. The fan 6 generates negative pressure in the filter box 7 through the collection pipe 5, and the dust and fibers generated during the rock wool cutting process flow towards the filter box 7 with the airflow; the dust-laden airflow first passes through the first filter plate 8, where large particles are intercepted; the remaining airflow containing fine fibers then passes through the second filter plate 9, where the fibers are captured, and the clean air is collected through the collection pipe 5. The fan 6 discharges air; when the equipment runs for a preset time or the pressure sensor detects that the airflow resistance in the filter box 7 exceeds the threshold, the telescopic device 10 is activated; the telescopic end of the telescopic device 10 extends vertically, driving the first cleaning component 11 and the second cleaning component 12 to enter the filter box 7 simultaneously, cleaning the first filter plate 8 and the second filter plate 9 respectively; after cleaning, the telescopic end of the telescopic device 10 retracts, driving the first cleaning component 11 and the second cleaning component 12 out of the filter box 7, and the equipment returns to the dust removal state, repeating the cutting and dust removal operations. Example 2:

[0023] This embodiment further defines the structure of the protective component based on the above embodiments, such as... Figures 2-4As shown, the dustproof assembly also includes a protective cover 13, which is fixedly connected to the upper surface of the workbench 1 and covers the outside of the cutting assembly. The top of the protective cover 13 has an air outlet, which is sealed to the end of the collection pipe 5 furthest from the filter box 7. The protective cover 13, covering the outside of the cutting assembly, confines the dust generated during rock wool cutting within a sealed space, preventing the dust from spreading unorganized to the periphery of the workbench 1 and reducing dust overflow. The air outlet at the top of the protective cover 13 is sealed to the collection pipe 5, ensuring that the dust-laden airflow in the sealed space can only enter the collection pipe 5 through the air outlet, forming a single airflow channel, improving negative pressure collection efficiency, and avoiding dust collection dead zones caused by airflow dispersion.

[0024] The specific implementation process is as follows: First, confirm that the protective cover 13 is fixed to the upper surface of the workbench 1 and completely covers the cutting components. The air outlet at the top of the protective cover 13 and the end of the collection pipe 5 furthest from the filter box 7 are sealed together and reinforced with a flange or sealing ring. Second, start the drive device 23 to rotate the cutting blade 16, pushing the rock wool board along the workbench 1 towards the cutting notch 2. The dust generated during the cutting process is confined inside the protective cover 13. Simultaneously, start the fan 6, creating a negative pressure inside the protective cover 13. The dust-laden airflow is drawn into the collection pipe 5 from the top air outlet. Subsequent filtration through the filter box 7 and discharge by the fan 6 is not described in detail. If it is necessary to inspect the cutting components or clean the inside of the protective cover 13, the equipment can be turned off and the protective cover 13 can be disassembled (e.g., it can be disassembled by bolts). After the operation is completed, reinstall it and ensure a seal to avoid affecting the subsequent dust removal effect. Other parts of this embodiment are the same as the above embodiments and will not be described in detail. Example 3:

[0025] This embodiment further defines the structure of the filter box 7 based on the above embodiments, such as... Figure 2 , Figure 4 As shown, the filter box 7 consists of a box body 14 and a sealing plate 15, wherein: The box 14 is a hollow structure with an open top. The top edge of the box 14 is sealed and fixedly connected to the lower end face of the workbench 1. The first filter plate 8 and the second filter plate 9 are both vertically fixed inside the box 14. The size of the sealing plate 15 is adapted to the size of the top opening of the box 14. The sealing plate 15 is fixedly connected to the telescopic end of the telescopic device 10. The first cleaning component 11 and the second cleaning component 12 are both fixed to the side of the sealing plate 15 facing the inside of the box 14. When the telescopic end of the telescopic device 10 extends, the sealing plate 15 can fit against the edge of the top opening of the housing 14, thus sealing the filter box 7. The top opening of the housing 14 is sealed to the lower end face of the workbench 1, ensuring that the dust-laden airflow can only enter the interior of the housing 14 without side leakage; the first filter plate 8 and the second filter plate 9 are vertically fixed inside the housing 14, ensuring that the airflow is in full contact with the filter plates; the size of the sealing plate 15 is adapted to the top opening of the housing 14 and is fixed to the telescopic end of the telescopic device 10. When dust removal, the telescopic device 10 retracts, and the sealing plate 15 fits against the top opening of the housing 14, thus sealing the filter box 7 and maintaining stable negative pressure; when cleaning, the telescopic device 10 extends, and the sealing plate 15 drives the cleaning components to enter the housing 14 simultaneously, eliminating the need for additional cleaning ports and simplifying the structure.

[0026] The specific implementation process is as follows: Before the equipment is started, the telescopic device 10 is in a retracted state, driving the sealing plate 15 to move towards the top opening of the housing 14 until the sealing plate 15 is in contact with the edge of the opening of the housing 14, forming a sealed space in the filter box 7; after the fan 6 is started, a stable negative pressure is generated inside the housing 14, and the dust-laden airflow passes efficiently through the first filter plate 8 and the second filter plate 9, with no airflow leakage from the opening; when the cleaning program is triggered, the telescopic end of the telescopic device 10 extends outward, driving the sealing plate 15 away from the opening of the housing 14. At the same time, the first cleaning component 11 and the second cleaning component 12 fixed below the sealing plate 15 enter the housing 14 along with the sealing plate 15, contacting the first filter plate 8 and the second filter plate 9 respectively and performing cleaning actions; after cleaning is completed, the telescopic end of the telescopic device 10 retracts, the sealing plate 15 drives the cleaning components out of the housing 14, and finally the sealing plate 15 re-closes the opening of the housing 14, the filter box 7 returns to a sealed state, and the dust removal operation continues. The other parts of this embodiment are the same as those in the above embodiment and will not be described again. Example 4:

[0027] This embodiment, based on the above embodiment, further adds a sealing gasket. A sealing gasket is fixedly connected to the edge of the housing 14 near the top opening. The sealing gasket is made of rubber and is used to enhance the sealing performance when the sealing plate 15 and the housing 14 are in contact, preventing dust from spreading from the gap between them. The rubber sealing gasket remains in its natural state when there is no pressure. When the sealing plate 15 is in contact with the opening of the housing 14, the sealing gasket is compressed and undergoes elastic deformation, which can fill the unevenness of the contact surface between the sealing plate 15 and the housing 14, preventing dust-laden airflow from leaking from the gap. The rubber material is wear-resistant and dust-resistant, and is not prone to failure with long-term use, improving the overall dust removal effect.

[0028] The specific implementation process is as follows: The rubber sealing gasket is fixed to the edge of the housing 14 near the top opening by adhesive or screws, ensuring that the gasket completely covers the perimeter of the opening and has a uniform thickness. After starting the fan 6, use your hand or a pressure testing instrument to check the contact point between the sealing plate 15 and the housing 14 to confirm there is no obvious airflow leakage. If leakage exists, the position of the sealing gasket can be adjusted or a gasket of suitable thickness can be replaced. After each cleaning operation, check the sealing gasket for damage or displacement. If the sealing gasket is severely worn, it can be directly removed and replaced with a new one. Maintenance is simple and convenient. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated. Example 5:

[0029] This embodiment further defines the structure of the first cleaning component 11 based on the above embodiments, such as... Figure 5 As shown, the first cleaning component 11 consists of a fixing frame 17 and a cleaning brush 18, wherein: The fixing frame 17 has an inverted U-shaped structure. The top of the fixing frame 17 is fixedly connected to the side of the sealing plate 15 facing the box 14, and the opening direction of the fixing frame 17 is consistent with the thickness direction of the first filter plate 8. The cleaning brush 18 is detachably connected to the inner wall of the fixing frame 17 via clips or bolts. The bristle length of the cleaning brush 18 is adapted to the thickness of the first filter plate 8. When the first cleaning component 11 enters the filter box 7, the bristles can contact and scrape the two side surfaces of the first filter plate 8. The opening direction of the inverted U-shaped fixing frame 17 is consistent with the thickness direction of the first filter plate 8, which allows the cleaning brush 18 on the inner wall of the fixing frame 17 to completely cover the two side surfaces of the first filter plate 8. During cleaning, the bristles generate friction with the surface of the filter plate, peeling off large particles of debris and preventing debris from getting stuck in the mesh. The cleaning brush 18 is detachably connected to the fixing frame 17 via clips or bolts. When the bristles wear down and the cleaning effect decreases, it is not necessary to replace the entire first cleaning component 11; only the cleaning brush 18 needs to be removed for replacement, reducing maintenance costs.

[0030] The specific implementation process is as follows: the cleaning brush 18 is fastened to the inner wall of the inverted U-shaped fixing frame 17 by snap-fit ​​or bolts, ensuring that the bristles face the inside of the opening of the fixing frame 17 and that the bristle length matches the thickness of the first filter plate 8; when the telescopic device 10 drives the first cleaning component 11 into the housing 14, the opening of the inverted U-shaped fixing frame 17 fits into the first filter plate 8, and the bristles of the cleaning brush 18 are in close contact with the two side surfaces of the first filter plate 8; the telescopic device 10 drives the first cleaning component 11 to move up and down vertically, and the bristles scrape off large particles of debris from the surface of the first filter plate 8 and inside the mesh by scraping, and the debris falls to the bottom of the housing 14 under gravity; after 1-2 months of use, if obvious wear of the bristles is observed, the equipment is turned off and the first cleaning component 11 is removed from the housing 14, the snap-fit ​​or bolts are removed, the old cleaning brush 18 is removed, a new cleaning brush is replaced and reinstalled to restore the cleaning function. The other parts of this embodiment are the same as those in the above embodiment and will not be repeated. Example 6:

[0031] This embodiment further defines the structure of the second cleaning component 12 based on the above embodiments, such as... Figure 5 As shown, the second cleaning component 12 consists of a mounting bracket 19, a diversion pipe 20, a nozzle 21, and a connecting pipe 22, wherein: The mounting bracket 19 is long and narrow, with one end of the mounting bracket 19 fixedly connected to the side of the sealing plate 15 facing the box 14, and the length direction of the mounting bracket 19 is parallel to the length direction of the second filter plate 9. The diversion pipe 20 is horizontally fixed to the side of the mounting bracket 19 away from the sealing plate 15, with one end of the diversion pipe 20 closed and the other end sealed to one end of the connecting pipe 22; Multiple nozzles 21 are provided, and the multiple nozzles 21 are evenly spaced along the length direction of the diversion pipe 20. The other end of the connecting pipe 22 extends out of the outside of the filter box 7 for a sealed connection with an external high-pressure gas source. The high-pressure gas provided by the external high-pressure gas source enters the diversion pipe 20 through the connecting pipe 22. One end of the diversion pipe 20 is closed and the other end is connected to the connecting pipe 22, which allows the high-pressure gas to be evenly distributed within the diversion pipe 20. Multiple nozzles 21 are evenly spaced along the length of the diversion pipe 20, with one nozzle every 10 cm. After the high-pressure gas is ejected through the nozzles 21, it forms multiple parallel airflows that can completely cover the entire surface of the second filter plate 9, effectively blowing off the fine fibers adsorbed on the surface of the second filter plate 9.

[0032] The specific implementation process is as follows: the air outlet of the external air compressor is sealed and connected to one end of the connecting pipe 22 extending outside the filter box 7 via a hose, and the hose interface is checked for leaks; when the telescopic device 10 drives the second cleaning component 12 into the box 14, the air compressor is started, and high-pressure gas enters the distribution pipe 20 through the connecting pipe 22, is distributed in the distribution pipe 20, and is simultaneously sprayed out through multiple nozzles 21; the airflow blows directly onto the surface of the second filter plate 9, blowing the adsorbed fine fibers away from the filter plate, and the fibers fall to the bottom of the box 14 with the airflow; during the cleaning process, the telescopic device 10 can drive the second cleaning component 12 to move slowly, further expanding the cleaning range; the air compressor pressure is adjusted according to the material of the second filter plate 9: if the filter plate material is thin, the pressure is adjusted to 0.4MPa to avoid high pressure damaging the filter plate; if the filter plate material is thick, the pressure can be adjusted to 0.6MPa to ensure the cleaning effect. The other parts of this embodiment are the same as those in the above embodiment, and will not be repeated. Example 7:

[0033] This embodiment further defines the structure of the second cleaning component 12 based on the above embodiments, such as... Figure 5 As shown, the air outlet of the nozzle 21 faces the surface of the second filter plate 9, and the axis of the nozzle 21 forms an angle of 30° to 60° with the surface of the second filter plate 9. If the angle is too small, less than 30°, the airflow is nearly parallel to the surface of the filter plate, resulting in insufficient impact force and difficulty in blowing off deeply adsorbed fibers. If the angle is too large, greater than 60°, the airflow impacts the filter plate almost vertically. Although the impact force is strong, it can easily cause some fine fibers to be pressed into the filter plate mesh, which can worsen the blockage and may damage the fiber structure of the filter plate. An angle of 30° to 60° allows the airflow to have sufficient impact force to strip the fibers, while also using oblique airflow to move the fibers away from the filter plate, avoiding them from being pressed into the mesh, reducing damage to the filter plate, and extending the service life of the filter plate.

[0034] The specific implementation process is as follows: When installing the second cleaning component 12, adjust the installation angle of the nozzle 21 so that the angle between the axis of the nozzle 21 and the surface of the second filter plate 9 is maintained between 30° and 60°, ensuring that the angle of all nozzles 21 is consistent; after starting the cleaning program, observe the fiber shedding on the surface of the second filter plate 9: if the fibers can quickly detach from the filter plate without obvious residue, it indicates that the angle is suitable; if there is still fiber residue, the angle can be finely adjusted until the cleaning effect meets the standard; after each replacement of the nozzle 21 or cleaning of the second cleaning component 12, recalibrate the nozzle angle to avoid angle deviation due to vibration or disassembly, and ensure stable cleaning effect. The other parts of this embodiment are the same as those in the above embodiment, and will not be repeated here. Example 8:

[0035] This embodiment further defines the structure of the cutting component based on the above embodiments, such as... Figures 2-4 As shown, the cutting component includes: The drive device 23 is a servo motor. The drive device 23 is fixedly connected to the outer wall of the protective cover 13. The output end of the drive device 23 is fixedly connected to one end of the output shaft through a coupling. The other end of the output shaft is rotatably connected to the inner wall of the protective cover 13 through a deep groove ball bearing. The cutting blade 16 is fixedly connected to the middle of the output shaft by a flat key, and the cutting edge of the cutting blade 16 extends into the cutting notch 2. The rotation trajectory of the cutting edge does not exceed the upper surface of the worktable 1. The servo motor 23 has the characteristic of precise and controllable speed, which can adjust the cutting speed according to the thickness of the rock wool board, avoiding the rock wool board from cracking due to excessive speed and the cut from roughness due to excessive speed. One end of the output shaft is connected to the output end of the servo motor 23 through a coupling, and the other end is rotatably connected to the inner wall of the protective cover 13 through a deep groove ball bearing, reducing the radial runout of the shaft and ensuring the stable rotation of the cutting blade 16. The cutting blade 16 is fixed to the output shaft by a flat key, which can prevent the blade from sliding circumferentially during rotation and ensure cutting accuracy. The cutting edge of the cutting blade 16 only extends into the cutting notch 2, and the rotation trajectory does not exceed the upper surface of the worktable 1, which can prevent the operator from accidentally touching the blade and causing a safety accident.

[0036] The specific implementation process is as follows: Based on the thickness of the rock wool board to be cut, the speed of the servo motor 23 is set to an appropriate value via the equipment controller to ensure that the cutting blade 16 can smoothly cut the rock wool board. The servo motor 23 is started, and the motor output drives the output shaft to rotate via a coupling. The output shaft rotates stably under the support of a deep groove ball bearing, simultaneously driving the cutting blade 16 to rotate synchronously. The operator pushes the rock wool board along the worktable 1 towards the cutting notch 2. The cutting blade 16 cuts the rock wool board within the cutting notch 2, resulting in a clean cut without significant dust splashing. Safety checks and maintenance: Before each startup, check whether the keyed connection of the cutting blade 16 is secure and whether the blade is sharp. Simultaneously, confirm that the blade rotation trajectory does not exceed the upper surface of the worktable 1. If the trajectory deviates, adjust the installation position of the output shaft to ensure effective safety protection. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.
