Abstract
The utility model relates to a cooling device of chamber type positive pressure oxygen breathing apparatus, which belongs to cooling devices of survival equipment and aims to solve the technical problems that in the prior positive pressure oxygen breathing apparatus, a cooling tank is arranged outside a breathing chamber, resulting in large volume of the breathing apparatus, excessive external pipeline connection, and poor cooling and sealing effects. The cooling device comprises a circular hollow cooling core body and a heat insulating sleeve fixed on the periphery of the cooling core body. Uniformly distributed filling blocks are arranged inside the cooling core body, and a semicircular groove is arranged on the outer side of the heat insulating sleeve. The device is arranged inside thebreathing chamber, and has the characteristics of small volume, light weight, and good cooling and sealing effects.
Description
Technical field
The utility model relates to a kind of lifesaving appliance cooling device, is specially a kind of storehouse formula positive pressure oxygen respirator cooling device.
Background technology
The positive pressure oxygen respirator that public mine rescue and fire-fighting, chemical defence are used is a kind of closed circuit respiratory circulatory system that is hedged off from the outer world, and the time wears the protective device of use for people operation or rescue in the toxic and harmful environment.Owing to be hedged off from the outer world, whole respiratory system is closed cycle, during use, and the carbon dioxide CO that human body is breathed out
2With the C in the peace and quiet jar
a(OH)
2The heat that chemically reactive produces will make suction temperature constantly raise, and feel comfortable temperature in order to make temperature be reduced to human body when air-breathing, and present storehouse formula positive pressure oxygen respirator is adorned a cooling tank outside breathing the storehouse, the cooling core is installed in jar.It is freezing to cool off core earlier before wearing, and when wearing respirator, cylindrical cooling core is packed in the respirator cooling tank.When air-breathing, gas through breathe the storehouse to connecting line again to air flue, inhaling hose, admission air valve between cooling tank and cooling core for people's breathing.Breathe outside the storehouse because cooling tank is placed on, this structure makes the respirator volume bigger, and external pipeline junction is more, and as misoperation, easily influence seals and service time.
Summary of the invention
For solve present positive pressure oxygen respirator cooling tank place breathe that the respirator volume that causes outside the storehouse is big, external pipeline connects many, cooling and the technical problem of sealing effectiveness difference, the utility model provides a kind of positive pressure oxygen respirator cooling device, this device is installed in breathes inside, storehouse, has that volume is little, in light weight, characteristics of cooling and good sealing effect.
The technical solution adopted in the utility model is: storehouse formula positive pressure oxygen respirator cooling device, comprise annular cavity cooling core body and the thermal insulation cover that is fixed on the cooling core body periphery, the built-in equally distributed filling block of cooling core body, the thermal insulation cover outside has semi-circular recesses.
During manufacturing, cooling in-core pack into neutral sponge filling block and cooling fluid, during use, cooling core body is fixed on the periphery of peace and quiet jar, the thermal insulation cover is sleeved on the cooling core body outside, the gas of exhalation enters from breathing the bottom, storehouse, enters the semi-circular recesses that puts by thermal insulation behind the storehouse on the breathing storehouse through peace and quiet jar and flows out from the air intake duct below the cooling core body.
What the utility model adopted is that cooling device is built in the structural design of breathing the storehouse, compares with the storehouse formula positive pressure oxygen respirator outside cooling system places the storehouse, has that volume is little, in light weight, easy to assembly, characteristics of cooling and good sealing effect.Add filling block in the filling chamber and match, changed the flowability of liquid, played slow releasing function with the loop configuration of filling the chamber.The thermal insulation cover can make the heat major part of gas reaction discharge in air through breathing Cang Gai, makes the loss of cooling fluid cooling energy reduce to minimum.
Description of drawings
Fig. 1 is the structural representation of storehouse formula positive pressure oxygen respirator cooling device.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, the 1-cooling core body; 2-thermal insulation cover; The 3-filling block; The 4-groove; The 5-aperture; The 6-boss.
The specific embodiment
Storehouse formula positive pressure oxygen respirator cooling device as shown in Figure 1, 2, comprises annular cavity cooling core body 1 and the thermal insulation cover 2 that is fixed on cooling core body 1 periphery, cooling core body 1 built-in equally distributed filling block 3, and thermal insulation is overlapped 2 outsides and is had semi-circular recesses 4.
The filling block 3 that adds is neutral sponge blocks, and filling block 3 is used to reduce the flowability of cooling fluid, plays slow releasing function, has increased the service time of cooling fluid.
As shown in Figure 1, cooling core body 1 has only upper surface and lateral surface to be covered by thermal insulation cover 2; Perhaps cooling core body 1 upper surface and side are covered by thermal insulation cover 2, and the lower surface is by thermal insulation cover 2 local coverings.Gas is cooled when flowing through cooling core body 1 lower surface, because the upper surface of cooling core body and side are covered by thermal insulation cover 2, reduced contacting of cooling core body 1 and ambient atmos, the heat major part of gas reaction is discharged in air through breathing Cang Gai, make the loss of cooling fluid cooling energy be reduced to minimum, the coolant seal effect is better, and is freezing and when assembling is easy to use, quick, improved complete machine performance and volume.
As shown in Figure 2, thermal insulation is overlapped 2 upper surfaces and is provided with aperture 5, and cooling core body 1 upper end is provided with the boss 6 that the aperture 5 that puts with thermal insulation cooperates, and boss is sleeved in the aperture, and thermal insulation cover 2 is fixed on the cooling core body 1.
The cross section of cooling core body 1 is a rectangle, and cooling core body 1 inboard is fixing with peace and quiet jar, and the outside is fixed with breathing storehouse inwall.
During concrete the manufacturing, with adding filling block 3 in the cooling core body 1, will cool off core cap bonding agent adhering and sealing earlier, cooling fluid is injected at the place by cooling core cap screwed hole, and the O RunddichtringO is inserted in the cover plug screw, it is contained in cooling core cap screwed hole place tightens.The middle part, breathing storehouse of storehouse formula positive pressure oxygen respirator is packed cylindrical peace and quiet jar into, the storehouse formula positive pressure oxygen respirator cooling device that installs is fixed on peace and quiet jar of periphery, the gas of exhalation flows to air intake duct in the cooling of cooling tank bottom after breathe the passage in storehouse on the storehouse by groove 4 again.
