On the other hand, the liquid level distance between the pressure relief pipe 25 and the liquid in the liquid storage tank 3 is increased, so that the detention time of high-temperature and high-pressure gas in the liquid storage tank 3 is prolonged, and the cooling efficiency is improved.
Fig. 2 is a side view of the explosion-proof box, and referring to fig. 2 again, in this embodiment, a plurality of pressure relief holes 251 in one group of pressure relief holes 251 are arranged at intervals along the circumferential direction of the outer wall of the pressure relief pipe 25, and a plurality of groups of pressure relief holes 251 are arranged at intervals along the axial direction of the pressure relief pipe 25.

The dust exhaust port 231 provides a passage for dust and dirt accumulated in the dust blocking box 23 to flow from the inside of the box body 1 to the outside of the box body 1, and the ventilation fan 26 ventilates the dust and the dirt so that the dust and the dirt are exhausted from the inside of the box body 1 along the dust exhaust port 231 under the driving of airflow.
Referring to fig. 1 again, in the present embodiment, one side of the cabinet 1 has an opening 11, and the opening 11 has a door 12, and the door 12 can open or close the opening 11 of the cabinet 1.
The joint surface clearance between box 1 and chamber door 12 has decided explosion-proof box's flame proof effect to a certain extent, and the clearance size and the roughness in joint surface clearance are explosion-proof box's flame proof effect's prerequisite, and the minimum size of regulation joint surface is in order to guarantee that the produced flame of explosion can not scurry the external world through the joint surface clearance in box 1, ignites the gas among the external environment, guarantees explosion-proof box's safety in utilization.
By providing the box door 12 according to the embodiment of the present disclosure, the opening 11 of the box body 1 can be opened or closed, and the joint surface gap between the box body 1 and the box door 12 can be kept from being affected by the use environment for a long time, so that the explosion-proof effect of the explosion-proof box can be improved, and the stability and reliability of the explosion-proof box can be improved.
Because the fan case 21 has strengthened the mobility of the interior air of explosion-proof case's box 1 to the flowing direction of air current is from box 1 inside to box 1 outside, make the composition surface clearance department in the box 1 can produce inward little air current, little air current can effectively restrain the deposit of dust and dirt at composition surface clearance department, finally drive dust and dirt by the operation of fan case 21 and leave in the box 1, simultaneously, the little air current that fan case 21 produced also can restrain the flame that the explosion produced, the trend of diffusing outward to box 1, the security and the reliability of explosion-proof case have been strengthened.
Illustratively, the door 12 may be constructed of aluminum bronze, which has high strength, wear resistance, and corrosion resistance, and does not produce sparks upon impact.
Illustratively, the minimum effective width of the interface of the door 12 and the cover of the explosion-proof case should be no less than 25mm.
Optionally, a high-voltage electrostatic coating is sprayed on the surfaces of the box door 12 and the box cover of the explosion-proof box to isolate the interior of the explosion-proof box from the external environment.
In this embodiment, the explosion proof tank further comprises a controller 4 and a travel switch 5.
The controller 4 and the travel switch 5 are both positioned in the box body 1, the controller 4 is respectively connected with the travel switch 5 and the fan box 21, and the travel switch 5 is positioned at the opening 11.
The travel switch 5 is located in the direction that the controller 4 is far away from the fan box 21, the travel switch 5 is set to be in a contact type, the plane where the contact of the travel switch 5 is located is consistent with the plane of the opening 11 on one side of the box body 1, the controller 4 and the travel switch 5 are both connected with the box body 1, one ends of a power line and a signal line of the controller 4 are connected with the fan box 21, and the other ends of the power line and the signal line of the controller 4 are connected with the travel switch 5.
The controller 4 and the travel switch 5 are both used for controlling the fan box 21 of the explosion-proof box to operate, and the negative pressure component 2 does not work under the state that the box door 12 is opened. After the door 12 is closed, the door 12 contacts with a contact of the travel switch 5 near the door 12, the travel switch 5 is activated, a signal is transmitted to the controller 4 through a power line and a signal line, and the controller 4 sends a command to operate the fan box 21. The automation of explosion-proof box has been improved, the space occupancy that reduces has improved explosion-proof box's integrated level.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
