Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, in particular to an electrical digital low-voltage switch cabinet. Background Art

[0002] Driven by innovative IoT technologies, the smart power distribution market is expected to continue its rapid growth. With the rapid development of smart grids, the demand for intelligent, networked, and information-based power equipment is increasing. As a key component of smart grids, digital low-voltage cabinets must be able to quickly integrate into the power system and achieve efficient, flexible, and secure power distribution and management.

[0003] Traditional low-voltage cabinets face long installation and commissioning times, high costs, and a high risk of misoperation during on-site installation and commissioning. Digital low-voltage cabinets with factory-connected functionality, with pre-installed interoperability settings, significantly simplify on-site installation and commissioning, improving the safety and efficiency of operations and maintenance. Digitalization improves equipment efficiency, extends service life, and reduces maintenance costs. Factory-connected low-voltage cabinets enable data recording and status monitoring throughout the entire equipment process, from design and production, installation, operation, to decommissioning.

[0004] To sum up, with the deepening advancement of intelligent and networked power systems and the industry's high standards for efficient operation and maintenance, safety and reliability, and full life cycle management of equipment, the research and development and promotion of digital low-voltage cabinets with factory-connected functions are particularly necessary. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an electrical digital low-voltage switchgear, comprising: a cabinet body, a cabinet door rotatably mounted on the outer surface of the cabinet body, a processor fixedly mounted on the surface of the cabinet door, a cabinet panel fixedly mounted on the interior of the cabinet body, a temperature and humidity sensor fixedly mounted on the interior of the cabinet panel, the temperature and humidity sensor being connected to the processor via electrical signals, and a flow cavity provided on the surface of the cabinet body away from the cabinet door; A heat dissipation component is used for cooling and ventilating the cabinet. Two groups of heat dissipation components are provided. The outer surfaces of the two groups of heat dissipation components are fixedly mounted with mounting plates, and the mounting plates are fixedly mounted on the outer surface of the cabinet; A filter assembly is used to filter dust from the circulating air when the cabinet is cooled. Two filter assemblies are provided, and both filter assemblies are fixedly mounted on the top of the heat dissipation assembly; The regulating assembly is fixedly mounted on top of the filter assembly and is located above the cabinet. Before the low-voltage switchgear leaves the factory, staff pre-install a communication module and cloud platform interface in the cabinet, enabling direct connectivity with the cloud control system. The temperature and humidity sensors installed in the cabinet panels often use high-precision models such as SHT3X and DHT. Wires connect the temperature and humidity sensors to the processor installed in the switchgear, transmitting digital signals in real time. The processor acts as an "intermediate hub," receiving temperature and humidity data from the sensor on one end and connecting to the regulating assembly's drive circuit on the other. When the sensor detects high cabinet temperature and humidity, it transmits a corresponding current signal to the processor. After analyzing the signal through an internal program, the processor sends a trigger command to the relay, closing the relay contacts and connecting the regulating assembly's power supply circuit, enabling the regulating assembly to start operating. As the regulating assembly delivers air, air passes through the filter assembly, where it absorbs and filters impurities before being transported to the heat dissipation assembly to cool and dehumidify the switchgear.

[0006] Preferably, the heat dissipation assembly includes an air supply pipe, with a double-ended pipe and a connecting pipe fixedly mounted on both ends of the air supply pipe, each of which has an air filter guide fixedly mounted on its outer surface, and a friction cleaning member fixedly mounted on the interior of each of the air filter guides, the friction cleaning member being frictionally adapted to the air filter guide. The air is adsorbed and filtered by the filter assembly and transported into the double-ended pipe, the air supply pipe, and the connecting pipe. The air filter guides mounted on the exterior of the double-ended pipe and the connecting pipe are in communication with the flow cavity. The installation of multiple sets of air filter guides expands the range of air transport, thereby improving the cooling efficiency.

[0007] Preferably, two groups of the air filter guides are provided, both groups of the air filter guides are fixedly connected to the mounting plate, the air filter guides are fixedly connected to the outer surface of the cabinet through the mounting plate, and the air filter guides are communicated with the flow cavity.

[0008] Preferably, the air filter guide includes a ring, the outer surface of the ring is fixedly mounted with a guide cover, the outer surface of the guide cover is fixedly mounted with a filter plate, the inside of the filter plate is fixedly mounted with a mounting bracket, the surface of the filter plate is provided with a guide hole, the inner surface of the guide cover is fixedly mounted with a mounting ring, the outer surface of the mounting ring is movably mounted with a buckle, six buckles are provided, and flexible scraping belts are fixedly mounted on the outer surfaces of the six buckles. The filtered air is respectively delivered to the air duct through the double-ended connecting pipe and the connecting pipe. The flexible scraper installed at the air inlet of the air duct through the buckle swings in the air duct relying on the air flow generated by the air flow to clean the dust and flocculent impurities attached to the surface of the filter plate. The flexible scraper is made of nylon ribbon material, which can be cut to length according to the size of the filter plate and fixed to the air flow channel of the air duct by buckles for easy disassembly and replacement. The flexible scraper with ribbon texture is relatively soft and has elastic friction when in contact with the filter plate, which can effectively clean light impurities such as dust and fiber attached to the surface, and avoid the wear and tear of the filter plate caused by traditional metal scrapers or hard brushes.

[0009] Preferably, the collars are respectively mounted on the outer surfaces of the double-ended connecting pipe and the connecting pipe, the filter plate is fixedly mounted inside the mounting plate, the guide hole is connected to the flow chamber, the mounting bracket is fixedly connected to the friction cleaning member, and the flexible scraper belt is configured to be a wear-resistant nylon material, and the flexible scraper belt is frictionally adapted to the filter plate and the friction cleaning member. When the switch cabinet is in operation, the flexible scraper belt can continuously and dynamically clean the filter plate to prevent impurities from accumulating and clogging the pores. This maintains the stable ventilation volume of the filter plate, ensures the heat dissipation efficiency of the electrical components within the switch cabinet, and indirectly guarantees the accuracy of temperature monitoring and data transmission.

[0010] Preferably, the friction cleaning member includes a mounting bar, which is fixedly mounted on the outer surface of the mounting frame. A limit frame is fixedly mounted on the outer surface of the mounting bar. Connecting rods are fixedly mounted on both sides of the limit frame. A curved rod is fixedly mounted on the interior of the connecting rod. A friction ball is fixedly mounted on the outer surface of the curved rod. The friction ball is frictionally adapted to the flexible scraper belt. When the flexible scraper belt is driven by the airflow to swing within the air guide cover, it contacts the surface of the friction ball. As the flexible scraper belt swings to clean the filter plate, some dust, fiber, and other impurities are absorbed by the surface. If accumulated over a long period of time, these impurities may fall back onto the filter plate due to the swinging of the flexible scraper belt, or enter the cabinet with the airflow, causing secondary pollution. When the flexible scraper belt collides with the friction ball, the vibration of the flexible scraper belt and the physical impact of the friction ball will shake off the attached dust to the bottom of the air guide cover. At this time, the dust on the surface of the flexible scraper belt can be cleaned to prevent the ribbon from reducing its swinging activity due to the weight.

[0011] Preferably, the adjustment assembly includes an inclined tube, a positioning seat fixedly mounted on the outer surface of the inclined tube, a housing fixedly mounted on the outer surface of the positioning seat, a motor fixedly mounted on the outer surface of the housing, a fan blade fixedly mounted on the output end of the motor, the fan blade rotatably mounted inside the housing, and the motor connected to the processor via electrical signals. When the sensor detects that the temperature and humidity inside the cabinet are high, the processor receives the signal and controls the motor to start, so that the output end of the motor drives the fan blade to rotate within the housing. At this time, the fan blade rotation draws air outside the switch cabinet into the inclined tube, which is connected to the connecting groove, thereby conveying the air into the filter guide for filtering and pre-treatment of the air to reduce the amount of impurities carried by the air during heat dissipation of the switch cabinet.

[0012] Preferably, the filter assembly includes a shell, a connecting groove is provided in the middle of the outer surface of the shell, a connecting pipe is fixedly installed on the surface of the shell away from the connecting groove, a filter guide is fixedly installed inside the shell cavity, and a filling cavity is formed between the shell and the filter guide.

[0013] Preferably, the connecting groove is sleeved on the outer surface of the inclined tube, the connecting tube is fixedly connected to the double-ended connecting tube, and the interior of the filling cavity is filled with activated carbon particles.

[0014] Preferably, the filter guide includes a filter cover, two of which are provided, each of which has a filter groove on its surface. A double-layer cover and a diverter plate are fixedly mounted on the outer surface of the filter cover, each of which has a hollow cavity inside. The double-layer cover and the diverter plate are staggered on the outer surface of the filter cover. Air is injected into the filter cover along the inclined tube. The filter cover is configured as a semicircular structure. The filter groove on its surface first filters larger impurities in the air. The treated air enters the casing. The double-layer cover and the diverter plate extend the time the air stays in the casing. The evenly arranged diverter plates divert the air so that the air passes through the diverter plates and enters the filling cavity, so that the activated carbon particles in the filling cavity can adsorb and clean impurities in the air.

[0015] The present invention provides an electrical digital low-voltage switchgear cabinet. It has the following beneficial effects: 1. This electrical digital low-voltage switchgear detects high temperature and humidity inside the cabinet through a sensor. After receiving the signal, the processor controls the motor to start, so that the output end of the motor drives the fan blades to rotate inside the shell. At this time, the rotating fan blades draw air outside the switchgear into the inclined pipe. The inclined pipe is connected to the connecting groove, so that the air is transported to the filter guide for filtering and pre-treatment of the air to reduce the impurity content carried by the air when the switchgear dissipates heat.

[0016] 2. The electrical digital low-voltage switchgear is configured such that air is injected into the filter cover along an inclined pipe. The filter cover is configured as a semicircular structure. The filter slots on its surface first filter out larger impurities in the air. The treated air then enters the casing. The double-layer cover and the diverter plate extend the time the air stays in the casing. The evenly arranged diverter plates divert the air so that the air passes through the diverter plates and enters the filling cavity, so that the activated carbon particles in the filling cavity can adsorb and clean the impurities in the air.

[0017] 3. The electrical digital low-voltage switchgear transmits filtered air to the double-ended pipe, air supply pipe and connecting pipe through the filter assembly. The air filter guide installed on the outside of the double-ended pipe and the connecting pipe is connected to the flow cavity. By installing multiple sets of air filter guides, the range of air transmission is expanded, thereby improving the cooling efficiency.

[0018] 4. The electrical digital low-voltage switchgear delivers the filtered air to the air guide cover through the double-ended pipe and the connecting pipe respectively. The flexible scraper installed at the air inlet of the air guide cover by the buckle relies on the air flow generated by the air flow to swing in the air guide cover to clean the dust and flocculent impurities attached to the surface of the filter plate. The flexible scraper is made of nylon ribbon and can be cut to length according to the size of the filter plate. It is fixed to the inside of the air flow channel of the air guide cover by buckles for easy disassembly and replacement. The flexible scraper with ribbon texture is relatively soft and has elastic friction when in contact with the filter plate, which can effectively clean light impurities such as dust and fiber attached to the surface, and avoid wear and tear on the filter plate caused by traditional metal scrapers or hard brushes.

[0019] Fifth, this electrical digital low-voltage switchgear uses a flexible scraper belt driven by airflow to swing within the air deflector, where it comes into contact with the surface of the friction ball. As the scraper belt sweeps the filter plate, it absorbs impurities such as dust and fiber. If these impurities accumulate over time, they may fall back onto the filter plate due to the belt's swinging motion or enter the cabinet with the airflow, causing secondary contamination. When the scraper belt collides with the friction ball, the belt's vibration and the physical impact of the ball shake off the attached dust to the bottom of the air deflector. This cleansing of the scraper belt's surface prevents the belt from reducing its swinging activity due to the weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The first embodiment, as Figures 1 to 15 As shown, the present invention provides a technical solution: an electrical digital low-voltage switchgear, comprising: a cabinet body 3, a cabinet door 1 being rotatably mounted on the outer surface of the cabinet body 3, a processor 2 being fixedly mounted on the surface of the cabinet door 1, a cabinet plate 9 being fixedly mounted inside the cabinet body 3, a temperature and humidity sensor being fixedly mounted inside the cabinet plate 9, the temperature and humidity sensor being connected to the processor 2 via electrical signals, and a flow cavity 8 being provided on the surface of the cabinet body 3 away from the cabinet door 1; The heat dissipation assembly 4 is used for cooling and ventilating the cabinet 3. The heat dissipation assembly 4 is provided with two groups. The outer surfaces of the two groups of heat dissipation assemblies 4 are fixedly mounted with mounting plates 7. The mounting plates 7 are fixedly mounted on the outer surface of the cabinet 3. The heat dissipation assembly 4 includes an air supply pipe 43, with a double-ended pipe 41 and a connecting pipe 44 fixedly mounted on both ends of the air supply pipe 43. Air filter guides 42 are fixedly mounted on the outer surfaces of the double-ended pipe 41 and the connecting pipe 44. Friction cleaning members 45 are fixedly mounted on the interiors of the air filter guides 42, and the friction cleaning members 45 are frictionally adapted to the air filter guides 42. The air is adsorbed and filtered by the filter assembly 6 and transported into the double-ended pipe 41, the air supply pipe 43, and the connecting pipe 44. The air filter guides 42 mounted on the exteriors of the double-ended pipe 41 and the connecting pipe 44 are connected to the circulation chamber 8. The installation of multiple sets of air filter guides 42 expands the range of air transport, thereby improving the cooling efficiency.

[0024] There are two groups of air filter guides 42 , both of which are fixedly connected to the mounting plate 7 . The air filter guides 42 are fixedly connected to the outer surface of the cabinet 3 through the mounting plate 7 , and the air filter guides 42 are communicated with the circulation cavity 8 .

[0025] A filter assembly 6 is used to filter dust from the circulating air when the cabinet 3 is cooled. Two filter assemblies 6 are provided, and both filter assemblies 6 are fixedly mounted on the top of the heat dissipation assembly 4; The filter assembly 6 includes a shell 61, a connecting groove 63 is opened in the middle of the outer surface of the shell 61, a connecting pipe 62 is fixedly installed on the surface of the shell 61 away from the connecting groove 63, a filter guide 64 is fixedly installed inside the cavity of the shell 61, and a filling cavity 65 is formed between the shell 61 and the filter guide 64.

[0026] The connecting groove 63 is sleeved on the outer surface of the inclined tube 55 , the connecting tube 62 is fixedly connected to the double-ended connecting tube 41 , and the interior of the filling cavity 65 is filled with activated carbon particles.

[0027] The regulating assembly 5 is fixedly mounted on top of the filter assembly 6 and is disposed above the cabinet 3. Before the low-voltage switchgear leaves the factory, the staff pre-installs a communication module and a cloud platform interface in the cabinet 3, enabling the low-voltage cabinet to be directly connected to the cloud control system upon leaving the factory. The temperature and humidity sensor installed in the cabinet panel 9 is usually a high-precision model such as SHT3X or DHT11. A wire connects the temperature and humidity sensor to the processor 2 installed in the switchgear, transmitting digital signals in real time. The processor 2 acts as an "intermediate hub," receiving the temperature and humidity data from the sensor at one end and connecting the drive circuit of the regulating assembly 5 at the other end. When the sensor detects that the cabinet temperature and humidity are high, it transmits a corresponding current signal to the processor 2. After the processor 2 analyzes the signal through an internal program, it sends a trigger command to the relay, closing the relay contacts and connecting the power supply circuit of the regulating assembly 5, causing the regulating assembly 5 to start operating. During the air supply process of the regulating assembly 5, the air passes through the filter assembly 6, where impurities in the air are adsorbed and filtered before being transported to the heat dissipation assembly 4 to cool and dehumidify the switchgear.

[0028] The adjustment assembly 5 includes a tilted tube 55, a positioning seat 54 fixedly mounted on the outer surface of the tilted tube 55, a housing 53 fixedly mounted on the outer surface of the positioning seat 54, a motor 52 fixedly mounted on the outer surface of the housing 53, a fan blade 51 fixedly mounted on the output end of the motor 52, the fan blade 51 rotatably mounted inside the housing 53, and the motor 52 is connected to the processor 2 via electrical signals. When the sensor detects that the temperature and humidity inside the cabinet 3 are high, the processor 2 receives the signal and controls the motor 52 to start, so that the output end of the motor 52 drives the fan blade 51 to rotate inside the housing 53. At this time, the fan blade 51 rotates and draws air outside the switch cabinet into the tilted tube 55. The tilted tube 55 is connected to the connecting slot 63, thereby transporting the air to the filter guide 64 for filtering and pre-treatment of the air to reduce the amount of impurities carried by the air when the switch cabinet dissipates heat.

[0029] The second embodiment, based on the first embodiment, see Figures 4 to 9As shown, the air filter guide 42 includes a ring 421, and a guide cover 422 is fixedly installed on the outer surface of the ring 421. A filter plate 425 is fixedly installed on the outer surface of the guide cover 422. A mounting bracket 424 is fixedly installed inside the filter plate 425. A guide hole 423 is provided on the surface of the filter plate 425. A mounting ring 428 is fixedly installed on the inner surface of the guide cover 422. A buckle 427 is movably installed on the outer surface of the mounting ring 428. There are six buckles 427, and flexible scraping belts 426 are fixedly installed on the outer surfaces of the six buckles 427. The filtered air is respectively delivered to the air guide cover 422 through the double-ended pipe 41 and the connecting pipe 44. The flexible scraper 426 installed at the air inlet of the air guide cover 422 through the buckle 427 swings in the air guide cover 422 by relying on the air flow generated by the air flow to clean the dust and flocculent impurities attached to the surface of the filter plate 425. The flexible scraper 426 is made of nylon ribbon material and can be cut to a length according to the size of the filter plate 425. It is fixed to the air flow channel of the air guide cover 422 by the buckle 427 for easy disassembly and replacement. The flexible scraper 426 with a ribbon texture is relatively soft and has elastic friction when in contact with the filter plate 425, which can effectively clean light impurities such as dust and fiber attached to the surface, and can avoid the wear and tear of the filter plate 425 caused by traditional metal scrapers or hard brushes.

[0030] The collar 421 is respectively mounted on the outer surfaces of the double-ended pipe 41 and the connecting pipe 44. The filter plate 425 is fixedly mounted inside the mounting plate 7. The guide hole 423 is connected to the flow chamber 8. The mounting bracket 424 is fixedly connected to the friction cleaning member 45. The flexible scraper 426 is made of wear-resistant nylon and is frictionally adapted to the filter plate 425 and the friction cleaning member 45. When the switch cabinet is in operation, the flexible scraper 426 can continuously and dynamically clean the filter plate 425 to prevent impurities from accumulating and clogging the pores. This maintains the ventilation volume of the filter plate 425, ensures the heat dissipation efficiency of the electrical components in the switch cabinet, and indirectly guarantees the accuracy of temperature monitoring and data transmission.

[0031] The friction cleaning member 45 includes a mounting bar 455, which is fixedly mounted on the outer surface of the mounting frame 424. A limit frame 453 is fixedly mounted on the outer surface of the mounting bar 455. A connecting rod 452 is fixedly mounted on both sides of the limit frame 453. A curved rod 454 is fixedly mounted on the inner surface of the connecting rod 452. A friction ball 451 is fixedly mounted on the outer surface of the curved rod 454. The friction ball 451 is frictionally adapted to the flexible scraper 426. When the flexible scraper 426 is driven by the airflow to swing within the air guide 422, it will contact the surface of the friction ball 451. During the process of the flexible scraper 426 sweeping and swinging the filter plate 425, some dust, fiber and other impurities will be absorbed on the surface. If accumulated for a long time, these impurities may fall back onto the filter plate due to the swinging of the flexible scraper 426, or enter the interior of the cabinet 3 with the airflow, causing secondary pollution. When the flexible scraping belt 426 collides with the friction ball 451, the vibration of the flexible scraping belt 426 and the physical impact of the friction ball 451 will shake off the attached dust to the bottom of the air guide cover 422. At this time, the dust on the surface of the flexible scraping belt 426 can be cleaned to prevent the ribbon from reducing its swinging activity due to the weight.

[0032] The third embodiment, based on the first and second embodiments, see Figures 12 to 15 As shown, the filter guide 64 includes two filter covers 642, each of which has a filter slot 643 formed on its surface. A double-layer cover 641 and a diverter plate 644 are fixedly mounted on the outer surface of each filter cover 642. The double-layer cover 641 has a hollow cavity 645 formed inside. The double-layer cover 641 and the diverter plate 644 are alternately arranged on the outer surface of the filter cover 642. Air flows through the inclined pipe 55 into the filter cover 642, which is a semicircular structure. The filter slots 643 formed on its surface first filter larger impurities in the air. The treated air then enters the housing 61. The double-layer cover 641 and the diverter plate 644 extend the time the air stays in the housing 61. The evenly spaced diverter plates 644 divert the air so that it passes through the diverter plates 644 and enters the filling chamber 65, where the activated carbon particles in the filling chamber 65 adsorb and remove impurities in the air.

[0033] During use, before the low-voltage switch cabinet leaves the factory, the staff pre-installs the communication module and the cloud platform interface in the cabinet 3, so that the low-voltage cabinet can be directly connected to the cloud control system when it leaves the factory. The temperature and humidity sensors installed in the cabinet panel 9 often use high-precision models such as SHT3X and DHT11. The temperature and humidity sensors are connected to the processor 2 installed in the switch cabinet through wires to transmit digital signals in real time. The processor 2 serves as an "intermediate hub", receiving the temperature and humidity data of the sensor at one end and connecting the drive circuit of the adjustment component 5 at the other end. When the sensor detects that the temperature and humidity of the cabinet are high, it will transmit the corresponding current signal to the processor 2; after the processor 2 analyzes the signal through the internal program, it sends a trigger instruction to the relay, the relay contacts are closed, and the power supply circuit of the adjustment component 5 is connected, so that the adjustment component 5 starts to run. In the process of air supply by the adjustment component 5, the air will pass through the filter component 6, and the impurities in the air will be adsorbed and filtered by the filter component 6 before the air is transported to the heat dissipation component 4 to cool and dehumidify the switch cabinet.

[0034] When the sensor detects that the temperature and humidity inside the cabinet 3 are high, the processor 2 controls the motor 52 to start after receiving the signal, so that the output end of the motor 52 drives the fan blades 51 to rotate in the shell 53. At this time, the fan blades 51 rotate to suck the air outside the switch cabinet into the inclined tube 55. The inclined tube 55 is connected to the connecting groove 63, so that the air is transported to the filter guide 64 to filter and pre-treat the air to reduce the impurity content carried by the air when the switch cabinet dissipates heat.

[0035] The air is injected into the filter cover 642 along the inclined tube 55. The filter cover 642 is set to a semicircular structure. The filter groove 643 opened on its surface first filters the larger impurities in the air. The treated air enters the shell 61. The double-layer cover 641 and the diverter plate 644 extend the time that the air stays in the shell 61. The evenly arranged diverter plates 644 divert the air so that the air passes through the diverter plates 644 and enters the filling cavity 65, so that the activated carbon particles in the filling cavity 65 can adsorb and clean the impurities in the air.

[0036] The air after adsorption and filtration by the filter assembly 6 is transported to the double-ended pipe 41, the air supply pipe 43 and the connecting pipe 44. The air filter guide 42 installed on the outside of the double-ended pipe 41 and the connecting pipe 44 is connected to the flow cavity 8. By installing multiple sets of air filter guides 42, the range of air transportation is expanded, thereby improving the cooling efficiency.

[0037] The filtered air is respectively delivered to the air guide cover 422 through the double-ended pipe 41 and the connecting pipe 44. The flexible scraper 426 installed at the air inlet of the air guide cover 422 through the buckle 427 swings in the air guide cover 422 by relying on the air flow generated by the air flow to clean the dust and flocculent impurities attached to the surface of the filter plate 425. The flexible scraper 426 is made of nylon ribbon material and can be cut to a length according to the size of the filter plate 425. It is fixed to the air flow channel of the air guide cover 422 by the buckle 427 for easy disassembly and replacement. The flexible scraper 426 with a ribbon texture is relatively soft and has elastic friction when in contact with the filter plate 425, which can effectively clean light impurities such as dust and fiber attached to the surface, and can avoid the wear and tear of the filter plate 425 caused by traditional metal scrapers or hard brushes.

[0038] When the switchgear is in operation, the flexible scraper 426 continuously and dynamically cleans the filter plate 425, preventing impurities from accumulating and clogging the pores. This maintains a stable ventilation rate through the filter plate 425, ensuring efficient heat dissipation for the electrical components within the switchgear and indirectly ensuring the accuracy of temperature monitoring and data transmission.

[0039] As the flexible scraper 426, driven by the airflow, swings within the shroud 422, it comes into contact with the surface of the friction ball 451. As the flexible scraper 426 sweeps and swings against the filter plate 425, it absorbs some impurities, such as dust and fibers, on its surface. If these impurities accumulate over time, they may fall back onto the filter plate due to the swinging of the flexible scraper 426, or enter the interior of the cabinet 3 with the airflow, causing secondary contamination. When the flexible scraper 426 collides with the friction ball 451, the vibration of the flexible scraper 426 and the physical impact of the friction ball 451 shake off the attached dust to the bottom of the shroud 422. This cleansing of the dust on the surface of the flexible scraper 426 prevents the belt from being subjected to reduced swinging activity due to the weight of the belt.
