Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of explosion venting cabinet, and this explosion venting cabinet can solve the problem that pressure transient easily appears in anti-explosion cabinet and soda acid cabinet.
For solving the problem, the technical scheme that the utility model adopts is as follows:
A kind of explosion venting cabinet, the top board of this explosion venting cabinet is provided with air vent, its top is provided with operating room and operation window, its underpart is provided with anti-explosion cabinet and soda acid cabinet, this air vent is connected with operating room, this operation window is installed on the front of operating room, and described air vent is connected with blast pipe, and this blast pipe is connected with the explosion venting hole of anti-explosion cabinet and the soda acid air vent of soda acid cabinet.
Preferably, described blast pipe is the three-way pipe with three connectors, and three connectors are connected with air vent, explosion venting hole and soda acid air vent respectively.
Preferably, described explosion venting hole and soda acid air vent are located at the back side of anti-explosion cabinet and soda acid cabinet respectively, and described blast pipe is arranged on the back side of explosion venting cabinet.
Preferably, the sidewall of described explosion venting cabinet is provided with wind complement port and ventilation slot, and this ventilation slot is located in the sidewall of explosion venting cabinet, and one end of ventilation slot is connected with the benefit wind box communicated with operating room, the other end is connected with wind complement port, and the path of ventilation slot is provided with check-valves.
Preferably, described benefit wind box is provided with blinds hole to be opened/closed.
Preferably, the top board of described explosion venting cabinet has convexed to form gas skirt, and described air vent is located on gas skirt.
Compared to existing technology, the beneficial effects of the utility model are:
Gas in anti-explosion cabinet and soda acid cabinet can be discharged by blast pipe; Time as denseer in the acidic and alkaline gas in soda acid cabinet, acidic and alkaline gas can be discharged by blast pipe, avoids operator to suck excessive acidic and alkaline gas when opening soda acid cabinet, to ensure the safety of operating personnel, also can reduce the peculiar smell in soda acid cabinet; In addition, when the air pressure in anti-explosion cabinet is higher, the gas in anti-explosion cabinet can be discharged by blast pipe, to ensure that the air pressure in anti-explosion cabinet keeps stable, avoids blasting because air pressure is too high, has ensured the safety of operating personnel equally.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 to 3, the top board of explosion venting cabinet described in the utility model convex to form possess air vent 1 gas skirt 11, top is provided with operating room 12 and operation window 13, bottom are provided with anti-explosion cabinet 9 and soda acid cabinet 10, this air vent 1 is connected with operating room 12, this operation window 13 is installed on the front of operating room 12, described air vent 1 is connected with blast pipe 4, and this blast pipe 4 is connected with the explosion venting hole 8 of anti-explosion cabinet 9 and the soda acid air vent 7 of soda acid cabinet 10.
Wherein, described blast pipe 4 is for having the three-way pipe of three connectors, and three connectors are connected with air vent 1, explosion venting hole 8 and soda acid air vent 7 respectively.And described explosion venting hole 8 and soda acid air vent 7 are located at the back side of anti-explosion cabinet 9 and soda acid cabinet 10 respectively, described blast pipe 4 is arranged on the back side of explosion venting cabinet.
In addition, the sidewall of described explosion venting cabinet is provided with wind complement port 2 and ventilation slot 14, and this ventilation slot 14 is located in the sidewall of explosion venting cabinet, and one end of ventilation slot 14 is connected with the benefit wind box 5 communicated with operating room 12, the other end is connected with wind complement port 2, and the path of ventilation slot 14 is provided with check-valves 3.Wherein, described benefit wind box 5 is provided with blinds hole 6 to be opened/closed.
By using the utility model, the gas in anti-explosion cabinet 9 and soda acid cabinet 10 can be discharged by blast pipe 4; Time as denseer in the acidic and alkaline gas in soda acid cabinet 10, acidic and alkaline gas can be discharged by blast pipe 4, avoids operator to suck excessive acidic and alkaline gas when opening soda acid cabinet 10, to ensure the safety of operating personnel, also can reduce the peculiar smell in soda acid cabinet 10; In addition, when the air pressure in anti-explosion cabinet 9 is higher, the gas in anti-explosion cabinet 9 can be discharged by blast pipe 4, to ensure that the air pressure in anti-explosion cabinet 9 keeps stable, avoids blasting because air pressure is too high, has ensured the safety of operating personnel.
And when the negative pressure in operating room 12 is excessive, the gas in operating room 12 can be discharged by wind complement port 2, to avoid the air pressure in operating room 12 excessive, ensure that the stable gas pressure in operating room 12; If when the air pressure in operating room 12 is too low, mends wind box 5 and by the gas make-up in the external world in operating room 12, can remain stable to make the air pressure in operating room 12.
When in operating room 12 air pressure continuous decrease time, check-valves 3 is opened because of the active force of negative pressure, so the air in the external world will be delivered in operating room 12, meanwhile, under the active force of air flowing, blinds hole 6 is also opened and is carried out changing wind with the external world, thus ensures that mending the enough smoothnesses of wind energy carries out, and returns to the scope of setting fast by the air pressure in operating room with this; When air pressure in room 12 to be operated returns to the scope of setting, check-valves 3 cuts out because the active force be subject to declines, and in ventilation slot 14, air flowing will stop then, so blinds hole 6 will be closed immediately, thus automatically stop carrying out benefit wind to operating room; In this way, vent cabinet can carry out benefit wind according to the negative pressure condition in operating room automatically, and whole process is automatically carried out, and without the need to setting up power source, not only mend air quantity sufficient, and device structure is simple, greatly reduces production cost.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
