Description

Technical Field

[0001] The utility model relates to the technical field of fire-resistant fuel system respirators, in particular to a respirator with strong adsorption capacity. Background Art

[0002] Fire-resistant fuel system breathers, also known as fuel tank breathers or fuel tank breathers, play a vital role in fire-resistant fuel systems. When the air pressure inside and outside the fuel tank is different, the fire-resistant fuel system breather can prevent air from being sucked into the fuel tank or allow air to be exhausted from the fuel tank, thereby maintaining the air pressure balance inside the fuel tank. This helps ensure that the fuel tank will not be damaged or malfunction due to air pressure problems during normal operation.

[0003] At present, most of the fire-resistant oil system respirators on the market use color-changing silica gel to absorb moisture in the air. The original color of the color-changing silica gel is dark blue. When it is saturated with moisture, the color changes from dark blue to light red. At this time, the color-changing silica gel is completely ineffective and the color-changing silica gel in the respirator needs to be replaced. However, the color-changing silica gel has the disadvantage of weak adsorption capacity. After absorbing a small amount of moisture, it will become saturated and lose the ability to absorb moisture. The adsorption effect is too low and the moisture in the air cannot be effectively treated. When the air enters the fire-resistant oil tank, the air still contains some moisture, which easily causes the problem of excessive moisture in the oil. Utility Model Content

[0007] The beneficial effect of the utility model is that when in use, one end of the filter element of the first tank body is connected to the fire-resistant oil tank, and by filling the first tank body with a molecular sieve, since the molecular sieve has a better ability to adsorb moisture than the color-changing silica gel, the molecular sieve can effectively adsorb moisture in the air, thereby enhancing the overall adsorption capacity of the device and solving the problem of weak adsorption capacity of the color-changing silica gel, thereby avoiding the phenomenon that the air still contains moisture when entering the fire-resistant oil tank, and avoiding the problem of excessive moisture in the oil when the fire-resistant oil system is in use.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] like Figures 1 to 5 As shown, embodiment 1 of the utility model is a respirator with strong adsorption capacity, including an adsorption component 2; the adsorption component 2 includes a first tank body 21, a filter mesh basket 24 is placed inside the first tank body 21, the filter mesh basket 24 in the first tank body 21 is filled with molecular sieves, and a filter element 23 is installed at the bottom of the first tank body 21.

[0024] When in use, one end of the filter element 23 of the first tank body 21 is connected to the fire-resistant oil tank 11. By filling the first tank body 21 with a molecular sieve, since the molecular sieve has a better ability to adsorb moisture than the color-changing silica gel, the molecular sieve can effectively adsorb moisture in the air, thereby enhancing the overall adsorption capacity of the device, solving the problem of weak adsorption capacity of the color-changing silica gel, and avoiding the phenomenon that the air still contains moisture when entering the fire-resistant oil tank 11, thus avoiding the problem of excessive moisture in the oil when the fire-resistant oil system is in use.

[0025] Embodiment 2 of the present utility model is a respirator with strong adsorption capacity. On the basis of embodiment 1, a plurality of electric heating tubes 5 are fixedly installed on the inner wall of the first tank body 21 .

[0026] Taking advantage of the opportunity that the fire-resistant oil tank 11 stops working when the unit is shut down for maintenance, the molecular sieve is heated by the electric heating tube 5 to volatilize the water adsorbed in the molecular sieve, thereby achieving the purpose of reusing the molecular sieve.

[0027] Embodiment 3 of the utility model is a respirator with strong adsorption capacity. On the basis of Embodiment 1 or 2, the adsorption component 2 also includes a second tank body 22 connected to the bottom of the first tank body 21, and a filter net basket 24 is also placed inside the second tank body 22. The filter net basket 24 in the second tank body 22 is filled with color-changing silica gel, and the material of the second tank body 22 is transparent glass. A filter element 23 is also installed at the bottom of the second tank body 22.

[0028] When in use, one end of the filter element 23 of the second tank body 22 is connected to the fire-resistant oil tank 11, and the air is dried by the first tank body 21 and then enters the second tank body 22, so that the color-changing silica gel can perform secondary adsorption of moisture in the air; the device adopts a dual moisture adsorption process of molecular sieve and color-changing silica gel, and the moisture absorption capacity is improved; at the same time, the second tank body 22 is set to be a transparent tank body, so that the staff can judge whether the adsorption capacity of the molecular sieve in the first tank body 21 is saturated according to the color of the color-changing silica gel, even if the device is under maintenance.

[0029] In the specific implementation, in order to further observe the state of the molecular sieve inside the first tank body 21, the material of the first tank body 21 is also transparent glass. In addition, the bottom of the filter net basket 24 is provided with a groove for placing the filter element 23. The filter element 23 is clamped at the bottom of the first tank body 21 and the second tank body 22 through the filter net basket 24.

[0030] Embodiment 4 of the utility model is a respirator with strong adsorption capacity. On the basis of embodiment 3, it also includes a fixing frame 3; the fixing frame 3 includes two fixing rings 31 in opposite shapes, a fixing plate 32 is arranged between the two fixing rings 31, and the upper surface and the lower surface of the fixing plate 32 are fixedly installed with a fixing rod 33 whose other end is fixedly connected to one side of the corresponding fixing ring 31, and the lower surface of the lower fixing ring 31 is fixedly installed with a support rod 34 in contact with the ground, and the upper and lower fixing rings 31 are fixedly connected to the surfaces of the first tank body 21 and the second tank body 22 respectively; the bottom of the second tank body 22 is connected to the gas pipeline 1, and the other end of the gas pipeline 1 is connected to the fire-resistant oil tank 11.

[0031] In the fire-resistant oil system, the traditional breathing structure is usually installed on the top of the fire-resistant oil tank 11. In the present invention, the first tank body 21 and the second tank body 22 are fixed by the cooperation of the fixing ring 31 and the support rod 34. At the same time, the second tank body 22 is connected to the fire-resistant oil tank 11 by setting the gas pipeline 1, so that the staff does not need to install the adsorption component 2 on the top of the fire-resistant oil tank 11, and can directly place the first tank body 21 and the second tank body 22 on one side of the fire-resistant oil tank 11. When the staff inspects the inside of the first tank body 21 and the second tank body 22, they do not need to climb onto the fire-resistant oil tank 11 to inspect them, thereby reducing the risk of personnel climbing and slipping.

[0032] Embodiment 5 of the utility model is a respirator with strong adsorption capacity. On the basis of embodiment 4, it also includes a lifting assembly 4 arranged between the first tank body 21 and the second tank body 22; the adsorption assembly 2 also includes an annular plate 25 fixedly sleeved on the open end of the filter net basket 24 of the second tank body 22; the lifting assembly 4 includes a positioning plate 41 arranged below the fixed plate 32, and the filter net basket 24 in the second tank body 22 is detachably mounted on the lower surface of the positioning plate 41 through the annular plate 25, and a plurality of electric push rods 42 are fixedly mounted on the upper surface of the fixed plate 32, and the movable ends of the plurality of electric push rods 42 extend to the bottom of the fixed plate 32 and are fixedly connected to the upper surface of the positioning plate 41, and a bellows 43 is connected to the lower surface of the first tank body 21, and the other end of the bellows 43 passes through the fixed plate 32 and the positioning plate 41 and is connected to the interior of the filter net basket 24 below.

[0033] When the color-changing silica gel inside the second tank body 22 needs to be replaced, the electric push rod 42 is started, so that the electric push rod 42 drives the positioning plate 41 to move upward. At the same time, the first tank body 21 and the second tank body 22 are connected by the bellows 43, so that when the positioning plate 41 moves upward, the bellows 43 can be compressed, so that the staff can move the filter net basket 24 out of the second tank body 22 without disassembling the first tank body 21. At this time, the color-changing silica gel inside the second tank body 22 can be replaced by only removing the filter net basket 24 from the positioning plate 41, which is convenient for the staff to replace the color-changing silica gel.

[0034] Embodiment 6 of the utility model is a respirator with strong adsorption capacity. Based on embodiment 5, an annular groove 10 is provided at the opening end of the second tank body 22, and a sealing ring 9 matching the annular groove 10 is provided on the lower surface of the positioning plate 41.

[0035] When the positioning plate 41 moves downward, the sealing ring 9 can move to the inside of the annular groove 10 , thereby improving the sealing performance of the second tank body 22 .

[0036] Embodiment 7 of the utility model is a respirator with strong adsorption capacity. On the basis of embodiment 4, a solenoid valve 6 is fixedly installed on the gas pipeline 1; a fixed cylinder 7 is fixedly sleeved on the gas pipeline 1, and a reinforcing rod 8 in contact with the ground is fixedly installed on the lower surface of the fixed cylinder 7.

[0037] By setting the fixing tube 7 and the reinforcing rod 8, the reinforcing rod 8 is in direct contact with the ground, providing additional support for the gas pipeline 1 and the fixing tube 7, thereby increasing the stability of the entire structure. When the color-changing silica gel in the second tank body 22 needs to be replaced, the air inside the gas pipeline 1 is cut off by closing the solenoid valve 6, thereby preventing the gas pipeline 1 from still transporting air to the inside of the fire-resistant oil tank 11 when the staff is inspecting the second tank body 22.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
