Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical management technology, and in particular to a chemical hazardous substance purification system. Background Technology

[0002] In the field of hazardous chemicals management, hazardous chemical storage cabinets are a very important piece of equipment.

[0003] Hazardous chemicals often exhibit volatility during storage. These volatile chemicals are corrosive and also flammable and explosive. Electronic devices typically contain control components such as circuit boards, which are highly susceptible to corrosion upon contact with volatile chemicals, potentially causing electrical sparks and damaging the circuitry. This makes the management of hazardous chemicals extremely difficult. As management becomes increasingly intelligent, it is crucial to properly protect these easily damaged electronic components. Traditional technologies are not suitable for protecting all electronic components within hazardous chemical storage cabinets. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a chemical hazardous substance purification system that can intelligently detect and purify harmful gases in hazardous chemical cabinets, while protecting the equipment circuits from corrosion by harmful gases. This utility model provides a chemical hazardous substance purification system, comprising: a frame, an exhaust module, a filter module, a monitoring module, a circuit module, and a protection module; the exhaust module is disposed within the frame and is used to guide the internal gas flow of the hazardous chemical cabinet into the frame; the filter module is movably disposed within the frame, located below the exhaust module, and is used to filter the hazardous gases guided into the frame by the exhaust module; the monitoring module is disposed within the frame, located below the filter module, and is used to detect the concentration, temperature, and humidity of the hazardous gases; the circuit module includes a circuit board, which is disposed within the frame, located above the filter module, and is used to control the exhaust module and the monitoring module; the protection module includes an isolation component and a sealing component; the isolation component is wrapped around the outer layer of the circuit board to reduce the contact of the circuit board with the hazardous gases, and the sealing component is disposed around the filter module to reduce the flow of hazardous gases outside the frame. This design, by using an insulating component to enclose the circuit board, reduces the circuit board's contact with harmful gases. Combined with a sealing component, it reduces the flow of harmful gases outside the frame, allowing for more thorough filtration of harmful gases. This reduces the corrosion of the overall purification system by harmful gases, extends its service life, and allows for more intelligent control and management of the hazardous chemical cabinet. The concentration, temperature, and humidity of harmful gases are detected before filtration, and purification only proceeds after the threshold is reached.

[0005] In one embodiment, the isolation component includes: a housing and a protective layer. The housing is fixedly disposed within the frame, and the circuit board is disposed within the housing. The protective layer wraps around the surface of the circuit board, and the outer surface of the protective layer is attached to the inner wall of the housing. The protective layer is applied using a potting process, where the circuit board is potted with adhesive. When at least two layers of adhesive are applied, at least one layer of the protective layer wraps around the surface of the circuit board, and the outer surface of at least one layer of the protective layer is attached to the inner wall of the housing. In this embodiment, only one layer of adhesive is applied.

[0006] This design, by potting the outer layer of the circuit board, seals the circuit board and isolates it from harmful gases. The outer shell further protects the potted circuit board, with the potted outer layer adhering to the inner layer of the shell, making it difficult for harmful gases to enter, thus further enhancing the protection of the circuit board.

[0007] In one embodiment, the sealing assembly includes: at least two seals, a sealing cap, and a wiring connection assembly, wherein at least one of the seals is located at the connection between the filter module and the air intake module; the sealing cap is detachably mounted on the frame for replacement of the filter module, and at least one of the seals is disposed at the connection between the sealing cap and the frame; the wiring connection assembly is used to electrically connect the circuit board, the air intake module, and the monitoring module.

[0008] This setup, by using two seals to seal the upper and lower parts of the filter module respectively, allows harmful gases to flow only through the filter module, preventing them from leaking out of the equipment, thus reducing the filtration effect and affecting the detection accuracy of the monitoring module. Using a single seal to completely disassemble and seal the filter module further enhances the airtightness, preventing gaps from allowing harmful gases to flow due to disassembly and reassembly.

[0009] In one embodiment, the wire connection assembly includes: a protective component, a wiring channel, and at least three connecting wires. The protective component passes through all the protective layers and connects to the circuit board. The wiring channel is formed within the protective component. All the connecting wires are disposed within the wiring channel and are connected to the circuit board. At least one of the connecting wires is electrically connected to the air-expelling module, and at least two of the connecting wires are electrically connected to the monitoring module.

[0010] This design protects the wires output from the circuit board from harmful gases, as repairing the wires becomes too cumbersome after the circuit board is potted. Protecting the wires reduces the risk of damage and facilitates maintenance of the overall purification system.

[0011] In one embodiment, the air intake module includes: a fan, a dustproof component, at least two air intakes, at least two sealing caps, and at least two sealing gaskets. The fan is disposed within the frame; the dustproof component is disposed on the frame and connected to the fan; at least one air intake is located at the bottom of the frame, and at least one air intake is located on the periphery of the frame. All air intakes are located below the filter module. The air intake module further includes that each sealing cap can be detachably installed on each air intake; and each sealing gasket is fixedly installed at the connection between each sealing cap and each air intake.

[0012] This configuration, with one air inlet located at the bottom of the frame and the other four air inlets positioned on the four sides of the frame, adapts to different application scenarios for hazardous chemical cabinets. Each air inlet is equipped with a sealing cap and a sealing gasket, ensuring airtightness while providing multiple air intakes and improving filtration efficiency. When the fan is drawing air, the corresponding sealing cap and sealing gasket are removed from the air inlets that require air intake, while the corresponding sealing cap and sealing gasket are installed at the air inlets that do not require air intake.

[0013] In one embodiment, the filter module includes a filter layer that is detachably mounted within the frame, located below the fan, and connected to at least one of the seals, the filter layer being filter cotton.

[0014] In one embodiment, the monitoring module includes a temperature and humidity detection device and a TVOC detection device, wherein the temperature and humidity detection device is disposed below the filter layer; the TVOC detection device is disposed on one side of the temperature and humidity detection device; and the temperature and humidity detection device and the TVOC detection device are respectively connected to at least one of the connecting lines.

[0015] With this setup, the concentration, temperature, and humidity of harmful gases in the air are detected by temperature and humidity detection devices and TVOC detection devices, thereby intelligently controlling the filtration.

[0016] In one embodiment, a display module is also included, which is disposed within the frame and connected to the circuit board, for displaying the operating status of the air intake module, the filter module, and the monitoring module.

[0017] This setup allows for comprehensive intelligent control by displaying the overall operation of the air intake module, filter module, and monitoring module and transmitting the data to the control terminal. This facilitates both control and observation by staff, such as monitoring the air intake module's rotation speed, the filter module's filter lifespan, and the concentration, temperature, and humidity of harmful gases in the monitoring module.

[0018] In one embodiment, the system further includes an anti-corrosion module comprising an electroplating layer; the frame is made of stainless steel, and the electroplating layer is applied to the surface of the frame through an electroplating process.

[0019] This design, by electroplating a metal layer onto all areas of the frame that come into contact with harmful gases, greatly reduces the corrosiveness of the gases.

[0020] Therefore, this utility model has the following advantages compared with the prior art:

[0021] 1. The chemical hazardous substance purification system of this utility model reduces the contact between the circuit board and the hazardous gas by using an isolation component to wrap the circuit board, and reduces the flow of hazardous gas to the outside of the frame by a sealing component. This makes the filtration of hazardous gas more thorough, reduces the corrosion of the overall purification system by hazardous gas, and extends the service life. Before filtration, the concentration, temperature and humidity of the hazardous gas are detected, and purification is carried out only after the threshold is reached. This provides more intelligent control and management of the hazardous chemical cabinet.

[0022] 2. According to the chemical hazardous substance purification system involved in this utility model, by potting the outer layer of the circuit board, the circuit board can be sealed, thereby playing the role of isolating harmful gases. In addition, the outer shell protects the circuit board after potting. The outer layer of potting is attached to the inner layer of the outer shell, making it difficult for harmful gases to enter, thereby further strengthening the protection of the circuit board.

[0023] 3. According to the chemical hazardous substance purification system involved in this utility model, this solution uses two sealing elements to seal the upper and lower positions of the filter module respectively, so that the hazardous gas can only flow through the filter module, preventing the hazardous gas from flowing out of the equipment, which would weaken the filtration effect and affect the detection accuracy of the monitoring module. In conjunction with a sealing element, the filter module is completely disassembled and sealed, which prevents the presence of gaps for the flow of hazardous gas due to the disassembly and installation of the filter module, thus enhancing the sealing performance.

[0024] 4. According to the chemical hazardous substance purification system involved in this utility model, this solution protects the wires output from the circuit board to prevent harmful gases from damaging the wires. Because after the circuit board is potted, repairing the wires is too cumbersome. Protecting the wires as a whole reduces the risk of damage and facilitates the maintenance of the overall purification system.

[0025] 5. According to the chemical hazardous substance purification system involved in this utility model, in this solution, one air inlet is set at the bottom of the frame, and the other four air inlets are respectively set on the four sides of the frame, so as to adapt to the application scenarios of different hazardous chemical cabinets. Each air inlet is equipped with a sealing cover and a sealing gasket, which ensures the airtightness while achieving the effect of multiple air intakes and improving the filtration efficiency.

[0044] See Figure 1-4 This utility model provides a chemical hazardous substance purification system, including a frame 10, an exhaust module 11, a filter module 12, a monitoring module 13, a circuit module 14, and a protection module 15. The exhaust module 11 is disposed within the frame 10 and is used to guide the internal gas flow of the hazardous chemical cabinet into the frame 10. The filter module 12 is movably disposed within the frame 10, located below the exhaust module 11, and is used to filter the hazardous gases guided into the frame 10 by the exhaust module 11. The monitoring module 13 is disposed within the frame 10, located below the filter module 15. Below group 12, the concentration, temperature, and humidity of harmful gases are detected; the circuit module 14 includes a circuit board 141, which is disposed within the frame 10 and above the filter module 12, for controlling the air intake module 11 and the monitoring module 13; the protection module 15 includes an isolation component 151 and a sealing component 152; the isolation component 151 is wrapped around the circuit board 141 to reduce the contact of the circuit board 141 with harmful gases, and the sealing component 152 is disposed around the filter module 12 to reduce the flow of harmful gases outside the frame 10.

[0045] Understandably, by using the design of the isolation component 151 to wrap the circuit board 141, the contact of the circuit board 141 with harmful gases is reduced. In conjunction with the sealing component 152, the flow of harmful gases to the outside of the frame 10 is reduced, so that the filtration of harmful gases can be more thorough, reducing the corrosion of harmful gases on the overall purification system and extending its service life. Before filtration, the concentration, temperature and humidity of harmful gases are detected, and purification is carried out only after the threshold is reached, which makes the control and management of the hazardous chemical cabinet more intelligent.

[0046] Combination Figure 1-4 As shown, the isolation component 151 includes: a housing 1511 and a protective layer 1512. The housing 1511 is fixedly disposed within the frame 10, and the circuit board 141 is disposed within the housing 1511. The protective layer 1512 is wrapped around the surface of the circuit board 141 and is attached to the inner wall of the housing 1511. The protective layer 1512 is made by potting adhesive, in which the circuit board 141 is potted. When at least two layers of adhesive are potted, at least one protective layer 1512 is wrapped around the surface of the circuit board, and the outer surface of at least one protective layer 1512 is attached to the inner wall of the housing 1511.

[0047] Understandably, in this solution, potting is done by potting the outer layer of the circuit board 141, which seals the circuit board 141 and isolates it from harmful gases. Then, the outer shell 1511 protects the potted circuit board 141. The outer layer of potting adheres to the inner layer of the outer shell 1511, making it difficult for harmful gases to enter, thereby further strengthening the protection of the circuit board 141.

[0048] Combination Figure 1-4 As shown, the sealing assembly 152 includes: at least two seals 1521, a sealing cover 1522, and a wire connection assembly. At least one seal 1521 is located at the connection between the filter module 12 and the air intake module 11. The sealing cover 1522 is detachably mounted on the frame 10 for replacement of the filter module 12. At least one seal 1521 is located at the connection between the sealing cover 1522 and the frame 10. The wire connection assembly is used to electrically connect the circuit board 141, the air intake module 11, and the monitoring module 13.

[0049] Understandably, in this solution, by using two sealing elements 1521 to seal the upper and lower positions of the filter module 12 respectively, harmful gases can only flow through the filter module 12, preventing harmful gases from flowing out of the equipment, which would weaken the filtration effect and affect the detection accuracy of the monitoring module 13. In conjunction with a sealing element 1521, the filter module 12 is completely disassembled and sealed, avoiding gaps that could allow harmful gases to flow due to the disassembly and installation of the filter module 12, thus enhancing the sealing performance.

[0050] Combination Figure 1-4 As shown, the wire connection assembly includes: a protective component, a wiring trough, and at least three connecting wires. The protective component passes through all protective layers 1512 and connects to the circuit board 141. The wiring trough is formed inside the protective component. All connecting wires are arranged in the wiring trough and are connected to the circuit board 141. At least one connecting wire is electrically connected to the air duct module 11, and at least two connecting wires are electrically connected to the monitoring module 13.

[0051] Understandably, this solution protects the wires output from circuit board 141 to prevent harmful gases from damaging them. After circuit board 141 is potted, repairing the wires becomes too cumbersome. Protecting the wires as a whole reduces the risk of damage and facilitates the maintenance of the overall purification system.

[0052] Combination Figure 1-4 As shown, the air intake module 11 includes: a fan 111, a dustproof component 112, at least two air intake ports 113, at least two sealing caps 114, and at least two sealing gaskets 115. The fan 111 is disposed within the frame 10; the dustproof component 112 is disposed on the frame 10 and connected to the fan 111; at least one air intake port 113 is opened at the bottom of the frame 10, and at least one air intake port 113 is opened on the periphery of the frame 10. All air intake ports 113 are located below the filter module 12. The air intake module 11 also includes that each sealing cap 114 can be detachably installed on each air intake port 113; and each sealing gasket 115 is fixedly installed at the connection between each sealing cap 114 and each air intake port 113.

[0053] Understandably, this solution adapts to different application scenarios of hazardous chemical cabinets by setting one air inlet 113 at the bottom of the frame 10 and setting the other four air inlets 113 on the four sides of the frame 10. Each air inlet 113 is equipped with a sealing cover 114 and a sealing gasket 115, which ensures airtightness and provides multiple air intakes, thus improving filtration efficiency. When the fan 111 is drawing air, the corresponding sealing cover 114 and sealing gasket 115 are removed from the air inlets 113 that require air intake, and the corresponding sealing cover 114 and sealing gasket 115 are installed at the air inlets 113 that do not require air intake.

[0054] Combination Figure 1-4 As shown, the filter module 12 includes a filter layer 121, which is detachably mounted in the frame 10, located below the fan 111, and connected to at least one seal 1521.

[0055] Combination Figure 1-4 As shown, the monitoring module 13 includes a temperature and humidity detection device 131 and a TVOC detection device 132. The temperature and humidity detection device 131 is located below the filter layer 121; the TVOC detection device 132 is located on one side of the temperature and humidity detection device 131; the temperature and humidity detection device 131 and the TVOC detection device 132 are respectively connected to at least one connecting line.

[0056] Understandably, the concentration, temperature, and humidity of harmful gases in the air are detected by the temperature and humidity detection device 131 and the TVOC detection device 132, thereby enabling intelligent control of filtration.

[0057] Combination Figure 1-4As shown, it also includes a display module, which is set inside the frame 10 and connected to the circuit board 141, for displaying the working status of the air intake module 11, the filter module 12 and the monitoring module 13.

[0058] Understandably, by displaying the overall operation of the air intake module 11, the filter module 12, and the monitoring module 13 and transmitting the data to the control terminal, it is convenient for both control and observation by the staff. For example, the rotation speed of the air intake module 11, the lifespan of the filter element in the filter module 12, and the concentration, temperature, and humidity of harmful gases in the monitoring module 13 can be monitored for further intelligent control.

[0059] Combination Figure 1-4 As shown, it also includes an anti-corrosion module 16, which includes an electroplating layer 161; the frame 10 is made of stainless steel, and the electroplating layer 161 is applied to the surface of the frame 10 by an electroplating process.

[0060] Understandably, by electroplating a metal layer onto all the areas of the frame 10 that come into contact with harmful gases, the corrosiveness of the harmful gases is greatly reduced.

[0061] The working principle of this hazardous chemical purification system is as follows: When the fan 111 is started, air enters through the air inlet 113 and is detected by the temperature and humidity detection device 131 and the TVOC detection device 132 to detect the temperature, humidity and concentration of hazardous gases (the temperature and humidity detection device 131 and the TVOC detection device 132 can detect even when the fan 111 is not rotating), thereby controlling the speed of the fan 111. Then the air flows through the guide flow to the filter layer 121 and is filtered. The filtered air flows out through the dustproof part 112 and is discharged to the external environment of the hazardous chemical cabinet. When the filter layer 121 needs to be replaced, the sealing cover 1522 is opened and replaced. The sealing cover 1522 is a snap-fit, and the snap-fit ​​position can be opened.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
