Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a dust-collecting chassis for a switch. Background Technology

[0002] With the rapid development of communication technology and the internet industry, the demand for network equipment in data centers, communication equipment rooms, and other locations is increasing daily, leading to the widespread application of switches as core network devices. During equipment operation, dust contamination has always been a significant factor affecting the stability and lifespan of switches. Switch dust removal technology has evolved from simple sealing and protection to active dust removal, gradually becoming a key technology for ensuring reliable equipment operation.

[0003] Currently, the mainstream dust removal technology for switches on the market mainly adopts dust filter solutions. Specifically, single or multiple layers of dust filters are installed at the air inlet of the chassis, using metal mesh or filter materials with different mesh sizes to block dust particles from entering the chassis. Some products also add a replaceable pre-filter layer outside the dust filter, extending the life of the main filter by periodically replacing the pre-filter layer. Although this passive dust prevention design is simple in structure, it has become the main technical means for dust prevention in current switches.

[0004] While commonly used dust prevention and removal technologies for switches have certain dust prevention and removal functions, in actual operation, the switch usually needs to be shut down for cleaning and maintenance, which affects the operating efficiency of the switch. Utility Model Content

[0014] An exhaust fan is installed on the side of the vortex separation chamber near the dust exhaust channel. The exhaust fan can purify and separate the outside air drawn in through the filter into purified air and dust, and the dust is discharged through the dust exhaust channel.

[0015] In one embodiment, the vortex separation cavity is spiral-shaped inside the separation shroud.

[0025] In one embodiment, the filter element is made of HEPA.

[0026] In one embodiment, the filtration accuracy of the filter element is 3 micrometers.

[0027] The technical solution of this utility model involves setting up a housing and a dust removal mechanism.

[0038] This utility model proposes a dust removal chassis for a switch.

[0039] Please see Figures 1 to 3In one embodiment of this utility model, a dust removal chassis for a switch includes a chassis 100 and a dust removal mechanism 200. One side of the chassis 100 forms an installation channel 110, and the dust removal mechanism 200 is installed in the installation channel 110. The dust removal mechanism 200 includes a filter element 210, a dust removal component 220, and a filter screen 230 installed sequentially from the inside to the outside in the installation channel 110. The dust removal component 220 has a vortex separation chamber 240 formed inside it. The two ends of the vortex separation chamber 240 are respectively connected to the filter screen 230 and the filter element 210. The vortex separation chamber 240 can separate the dust carried by the outside air drawn in by the filter screen 230, so that the dust-removed outside air enters the chassis from the filter element 210.

[0040] Specifically, in practical applications, the dust removal chassis of this application first filters outside air through filter 230 to remove larger particles. Then, the air carrying fine dust enters the vortex separation chamber 240. Inside the vortex separation chamber 240, the air forms a rotating airflow, and centrifugal force separates the dust particles, which are then deposited on the inner wall of the vortex separation chamber 240. The cleaned air then passes through filter 210 into the housing 100, providing clean cooling airflow for the switch.

[0041] This application establishes a triple-layer filtration and dust removal system by sequentially installing a filter element 210, a dust removal component 220, and a filter screen 230 from the inside out within the installation channel 110. The filter screen 230 serves as the first line of defense, filtering large particles; the vortex separation chamber 240 serves as the second line of defense, separating fine dust; and the filter element 210 serves as the third line of defense, further ensuring the cleanliness of the air entering the housing 100. This multi-layered protective structure effectively prevents dust from entering the housing 100, protecting the internal components of the switch.

[0042] The eddy current separation chamber 240 uses centrifugal separation to remove dust and has a self-cleaning function. Dust automatically deposits on the inner wall of the chamber under centrifugal force, eliminating the need for downtime for cleaning and maintenance. This self-cleaning function avoids the problems associated with traditional cleaning and maintenance, improving the operating efficiency of the switch. Furthermore, eddy current separation provides a continuous and stable dust removal effect, enabling effective operation for an extended period.

[0043] In this embodiment, by setting up a housing 100 and a dust removal mechanism 200, an installation channel 110 is formed on one side of the housing 100. The dust removal mechanism 200 is installed in the installation channel 110. The dust removal mechanism 200 includes a filter element 210, a dust removal component 220, and a filter screen 230 installed sequentially from the inside to the outside in the installation channel 110. A vortex separation chamber 240 is formed in the dust removal component 220. The two ends of the vortex separation chamber 240 are respectively connected to the filter screen 230 and the filter element 210. The vortex separation chamber 240 can separate the dust carried by the outside air drawn in by the filter screen 230, so that the dust-removed outside air enters the housing from the filter element 210. This allows the present invention to achieve cleaning and maintenance functions without shutting down the switch by using the housing 100 and the dust removal mechanism 200, thus ensuring the operating efficiency of the switch.

[0044] In one embodiment, the dust removal component 220 includes a dust separation component 221 and a dust removal and cleaning component 222. The dust separation component 221 has the vortex separation chamber 240 formed therein. The dust removal and cleaning component 222 is installed on the side of the dust separation component 221 facing the filter screen 230. The dust removal and cleaning component 222 can clean the dust adsorbed on the filter screen 230.

[0045] Specifically, outside air first undergoes preliminary filtration through filter 230, which blocks larger particles. As usage time increases, dust gradually accumulates on the surface of filter 230. At this point, the dust removal and cleaning component 222 promptly cleans the dust adsorbed on the surface of filter 230, preventing dust accumulation and clogging. Fine dust particles carried by the airflow through filter 230 enter the vortex separation chamber 240 of the dust separation component 221, where a rotating airflow is formed, using centrifugal force to separate the dust particles from the air.

[0046] It can continuously remove dust and clean the switch during operation without downtime maintenance. The dust removal and cleaning component 222 cleans the dust on the surface of the filter screen 230, maintaining the filtration effect of the filter screen 230 and preventing the filter screen 230 from becoming clogged and affecting airflow. At the same time, the dust separation component 221 further purifies the airflow through eddy current separation, ensuring the cleanliness of the air entering the housing 100.

[0047] In one embodiment, the dust separation assembly 221 includes a separation hood 2211 and an exhaust fan 2213. The filter screen 230 and the filter element 210 are respectively installed at both ends of the separation hood 2211. The vortex separation chamber 240 is formed inside the separation hood 2211. A dust discharge channel 2212 communicating with the vortex separation chamber 240 is formed on the side of the separation hood 2211 near the filter element 210. The exhaust fan 2213 is installed on the side of the vortex separation chamber 240 near the dust discharge channel 2212. The exhaust fan 2213 can purify and separate the outside air drawn in through the filter screen 230 into purified air and dust, and the dust is discharged through the dust discharge channel 2212.

[0048] Specifically, outside air is first pre-filtered through filter 230, and then enters the vortex separation chamber 240 inside the separation hood 2211. When the exhaust fan 2213 is working, it generates negative pressure inside the vortex separation chamber 240, causing the air to form a rotating airflow within the chamber. Due to centrifugal force, dust particles in the air are thrown against the chamber wall and separated from the airflow. The separated purified air continues to flow forward, passing through filter 210 and entering the housing 100 to provide clean cooling airflow for the exchanger.

[0049] An exhaust fan 2213 is installed on the side of the vortex separation chamber 240 near the dust discharge channel 2212. It generates directional airflow to actively discharge the separated dust through the dust discharge channel 2212 to the outside of the housing 100. This active dust discharge method prevents dust accumulation within the vortex separation chamber 240, maintaining the cleanliness of the chamber and ensuring a continuous and stable dust removal effect. The dust discharge channel 2212 is connected to the vortex separation chamber 240, providing a dedicated discharge path for the separated dust.

[0050] Through the coordinated action of the separation hood 2211, the exhaust fan 2213, and the dust exhaust channel 2212, the dust separation assembly 221 can achieve continuous purification of the outside air. The exhaust fan 2213 provides the power source, forming a stable rotating airflow within the vortex separation chamber 240, thereby improving dust separation efficiency. Simultaneously, the negative pressure generated by the exhaust fan 2213 allows the dust exhaust channel 2212 to effectively discharge the separated dust, preventing dust from circulating within the system.

[0051] In one embodiment, the vortex separation cavity 240 is spiral-shaped within the separation shroud 2211.

[0052] Specifically, after entering the separation hood 2211 through the filter 230, outside air flows along the spiral-shaped vortex separation chamber 240 under the action of the exhaust fan 2213. As the air moves in a spiral motion within the chamber, dust particles are thrown towards the outer wall of the chamber due to centrifugal force. Because the spiral structure increases the air's path, dust particles have more time to be separated under centrifugal force, thus improving dust separation efficiency.

[0053] The spiral-shaped vortex separation chamber 240 can also generate a stable airflow field, avoiding airflow turbulence. Air forms a regular rotating airflow within the spiral chamber, making the dust separation process more uniform and stable. At the same time, the spiral structure can reduce airflow resistance, lower energy consumption, and improve system operating efficiency.

[0054] In one embodiment, the dust removal and cleaning assembly 222 includes a bracket 2221, a drive component 2222, and a cleaning component 2223. The bracket 2221 is mounted on the side of the separation cover 2211 near the filter screen 230. The drive component 2222 is mounted on the bracket 2221, and the output shaft of the drive component 2222 is oriented towards the filter screen 230. The cleaning component 2223 is mounted on the output shaft of the drive component 2222. The drive component 2222 can drive the cleaning component 2223 to rotate so that the cleaning component 2223 can clean the dust adsorbed on the filter screen 230.

[0055] Specifically, the cleaning component 2223 rotates along the output shaft of the drive component 2222, continuously cleaning the surface of the filter screen 230. When outside air passes through the filter screen 230, larger particles are blocked and adsorbed onto its surface. Driven by the drive component 2222, the cleaning component 2223 promptly removes this adsorbed dust, preventing dust accumulation on the filter screen 230 surface. The dust removed by the cleaning component 2223 falls downwards due to gravity and does not enter the housing 100.

[0056] The mounting position of bracket 2221 ensures an appropriate distance between the drive component 2222 and the filter screen 230, allowing the cleaning component 2223 to maintain proper contact pressure with the surface of the filter screen 230. Excessive contact pressure will damage the filter screen 230, while insufficient contact pressure will not effectively remove dust. The precise positioning of bracket 2221 ensures the reliability of the cleaning process and the service life of the filter screen 230.

[0057] The drive unit 2222 can continuously and stably output power to drive the cleaning unit 2223 to rotate, thereby realizing the automatic cleaning function of the filter screen 230. The automatic cleaning method avoids manual cleaning and maintenance, enabling the exchanger to keep the filter screen 230 clean during operation and improving equipment operating efficiency.

[0058] In one embodiment, the cleaning component 2223 includes a mounting roller 2224 and a cleaning brush 2225. The mounting roller 2224 is mounted on the output end of the drive shaft, and the cleaning brush 2225 is mounted on the outer periphery of the mounting roller 2224. The drive component 2222 can drive the mounting roller 2224 to rotate the cleaning brush 2225 and clean the filter screen 230.

[0059] Specifically, the drive component 2222 drives the mounting roller 2224 to rotate, which in turn drives the cleaning brush 2225 on its outer periphery to rotate. The cleaning brush 2225 maintains appropriate contact pressure with the surface of the filter screen 230, and can continuously remove dust adsorbed on the surface of the filter screen 230 during rotation. The mounting roller 2224 serves as the carrier for the cleaning brush 2225, and its diameter is adapted to the installation position of the filter screen 230 to ensure that the cleaning brush 2225 can effectively contact the surface of the filter screen 230.

[0060] By mounting cleaning brushes 2225 on the outer periphery of the roller, a ring-shaped cleaning structure is formed, allowing the cleaning brushes 2225 to evenly clean the surface of the filter screen 230 as the mounting roller 2224 rotates, avoiding cleaning dead spots. At the same time, the coordinated use of multiple cleaning brushes 2225 improves cleaning efficiency and shortens the time required for a single cleaning cycle.

[0061] The cleaning brush 2225 is reliably fixed to the mounting roller 2224, ensuring that the cleaning brush 2225 will not fall off during high-speed rotation. When the cleaning brush 2225 wears out, it can be easily replaced with a new one, extending the service life of the cleaning component 2223. The drive component 2222 drives the mounting roller 2224 to rotate via an output shaft. The output shaft and the mounting roller 2224 are connected by a key to ensure reliable power transmission.

[0062] It should be specifically and clearly stated that the filter screen 230 is a steel mesh. The mesh size of the filter screen 230 is A, wherein 1 mesh ≤ A ≤ 50 mesh.

[0063] In one embodiment, the filter element 210 is made of HEPA. The filtration accuracy of the filter element 210 is 3 micrometers.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
