Description

Technical Field

[0001] The invention belongs to the technical field of the electronics industry and relates to a special gas cabinet with an explosion-proof function. Background Art

[0002] The principle of explosion-proof cabinets is to isolate combustible materials from ignition sources through explosion-proof technology to achieve explosion-proof purpose. The design of explosion-proof cabinets is mainly to enclose electrical components that may generate sparks due to high temperature or failure in a special box. The box has a multi-rib design to strengthen the structure. High-quality sealing strips and external explosion-proof interfaces are used to ensure that gas and dust cannot enter to improve the sealing performance. This can effectively isolate external combustibles and withstand the pressure generated by internal explosions without damage, while preventing flames or explosive gas mixtures from spreading from the inside of the box to the outside to cause greater harm.

[0003] To this end, we have optimized our conventional special gas equipment sheet metal cabinet and embedded the explosion-proof box for installing electrical components into the cabinet. The design of embedding the explosion-proof box into the special gas cabinet can better meet the requirements of these standards and regulations for the safe storage and protection of special gases, ensure that the use of special gases is legal and compliant, reduce the legal risks and safety hazards caused by non-compliance with regulations, and thus design a special gas cabinet with explosion-proof function.

[0015] In order to enable those skilled in the art to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0016] In the description of the present invention, it is necessary to understand that the orientation or position relationship indicated by the terms such as "up", "down", "left", "right", "inside", "outside", "horizontal" and "vertical" is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or original referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] The present invention will be described in detail below with reference to the accompanying drawings: Figure 1 As shown, a special gas cabinet with explosion-proof function includes a cabinet body 1, which is erected on a support platform 2, a support frame 3 is installed on the support platform 2, and the support frame 3 is composed of a left support frame 4 and a right support frame 5, wherein an electric control box 6 is installed in the left support frame 4, and a gas supply disk 7 is installed in the right support frame 5, and flip doors 8 are installed on the left support frame 4 and the right support frame 5, and an air valve 9 is opened on the top of the right support frame 5, and an explosion-proof shell 27 is installed outside the electric control box 6 in the left support frame 4.

[0018] like Figure 2-3 As shown, the explosion-proof housing 27 is a sealed housing, and a mounting assembly is arranged at the rear of the housing. Multiple wire tubes 10 are provided on both the upper and lower sides of the housing, and the cables of the electronic components in the electric control box can be passed through to connect to external devices. A protruding maintenance hole 11 is provided in the front of the housing, and an escutcheon 12 is installed outside the maintenance hole 11. A switch 13 for opening and closing is provided on one side of the escutcheon 12, and the other side is connected by a rotating shaft (not shown in the figure). An explosion-proof hole 14 is also provided on the escutcheon 12, and a transparent explosion-proof glass 15 is installed on the explosion-proof hole 14. The explosion-proof glass 15 is fixed to the explosion-proof housing 27 by bolts 29, and a handle 16 is installed on the explosion-proof glass 15 for easy opening. The explosion-proof glass provided in the present invention can roughly observe the internal situation, which is convenient for the staff to operate.

[0019] The mounting assembly consists of a lower mounting plate 17 and an upper mounting ring 18. The upper mounting ring 18 is located on both sides of the shell and is used to be sleeved in the hooks arranged on the electric control box 6. The lower mounting plate 17 and the upper mounting ring 18 are in the same position. The middle of the mounting plate 17 is concave to form a slot 19, which is inserted into the slot arranged on the electric control box 6 for fixation.

[0020] The wire tube 10 is installed between the upper mounting ring 18 and the lower mounting plate 17, and is provided with four wire holes, one of which has a wire hole larger than the other three wire holes. The large wire hole 21 serves as the inlet and outlet of the main line, the other two are the inlet and outlet of the auxiliary line 22, and the remaining one is a spare wire hole 23.

[0021] Of course, the number and position of the wire tubes can be adjusted according to actual conditions to meet actual needs without any limitation.

[0022] like Figure 4 As shown, the explosion-proof housing 27 is also provided with a control chip 24, and a display screen 25, an indicator light 26, and a button hole 20 are also provided on the explosion-proof housing 27. One end of the control chip 24 is connected to the electronic components 28 inside the electric control box 6, and the other end is connected to the display screen 25, the indicator light 26, and the button hole 20. An emergency stop button is installed in the button hole 20. The display screen 25 can display the data in the electronic components, and the normal situation of the data will be lit by the indicator light 26, and the emergency stop button can directly close the electric control box 6.

[0023] The present invention is also provided with a display screen, an indicator light and a button hole. The display screen is provided because the explosion-proof glass can only roughly observe the internal situation and cannot fully detect it. The equipped display screen can directly and in detail observe the data in the electronic components to prevent accidents. The indicator light can be red, yellow and green. When it is green, it shows normal, yellow is a warning, and red indicates an abnormality. The emergency stop button in the button hole can be used to immediately close the electric control box to prevent accidents.

[0024] The explosion-proof shell is generally made of special explosion-proof materials and has good explosion-proof and impact-resistant capabilities, thereby ensuring the life safety of the staff. Warning slogans such as "It is strictly forbidden to open the cover with power on" can also be printed or painted on the explosion-proof shell, thereby reducing and preventing accidents.

[0025] Since currently few domestic special gas cabinet manufacturers have obtained explosion-proof certification, the special gas cabinet with explosion-proof function designed by the present invention has the ability to be explosion-proof by placing electrical components in the explosion-proof cabinet. The explosion-proof cabinet is placed in the electric control box, which makes the overall appearance beautiful and reduces the probability of danger. The overall structure is simple and reasonable, easy to install, practical and safe.

[0026] The specific embodiments described herein are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
