Description

Technical Field

[0001] The invention belongs to the field of motor maintenance, and in particular relates to a carbon dioxide cylinder heating device. Background Art

[0002] During the overhaul of power plant units, in order to ensure safe operation, the hydrogen inside the generator must be safely replaced with air. Since hydrogen and air are very likely to cause explosions within a specific volume concentration range (4.0% to 75.6%), direct replacement is strictly limited. Therefore, we use carbon dioxide as an intermediate medium to ensure the safety of the operation in a step-by-step replacement manner. The specific steps involve first replacing the hydrogen in the generator with carbon dioxide, and then replacing the carbon dioxide with air, thereby successfully completing the replacement process;

[0003] When performing this replacement process, the liquid carbon dioxide stored in the carbon dioxide cylinder is used as the supply source. However, when the liquid carbon dioxide is converted into gas, it absorbs a large amount of heat, causing the surface of the cylinder to frost quickly, which in turn affects the smooth release of the liquid carbon dioxide. To overcome this problem, it is particularly important to properly heat the carbon dioxide cylinder.

[0004] Most of the heating equipment on the current market uses constant temperature heating. This fixed heating mode cannot be flexibly adjusted according to the actual changes in the surface temperature of the cylinder. Once the surface of the cylinder is no longer frosted, continuous constant temperature heating may cause excessive expansion of the gas in the cylinder and increase internal pressure, thus posing potential safety hazards. In addition, these heating devices usually rely on cumbersome manual operations or additional auxiliary equipment when loading and unloading carbon dioxide cylinders, which increases the complexity and labor intensity of the operation.

[0042] Also included is a carbon dioxide monitoring component for monitoring carbon dioxide leakage from a carbon dioxide cylinder.

[0043] The working principle and beneficial effects of the above technical solution are as follows: when the carbon dioxide cylinder needs to be heated, the carbon dioxide cylinder is lifted to the same level as the heating assembly by the lifting structure 6 of the placement assembly 5, and the placement assembly 5 moves the carbon dioxide cylinder to above the heating assembly 2 by sliding, and then the placement assembly 5 lowers the carbon dioxide cylinder onto the heating assembly 2, the placement assembly 5 supports the carbon dioxide cylinder, the carbon dioxide cylinder presses down the heating assembly 2 and triggers the switch structure 4, so that the heating assembly 2 heats the carbon dioxide cylinder after the circuit is connected, and when the carbon dioxide cylinder is heated, the weighing assembly 8 weighs and measures the carbon dioxide cylinder during the heating process, and the carbon dioxide monitoring assembly is used to monitor whether the carbon dioxide cylinder is leaking and to perform extraction according to the monitoring situation;

[0045] Example 2

[0046] On the basis of Example 1, the heating component 2 includes an insulating furnace 21, which is installed in the casing 1. An induction coil 22 is installed in the insulating furnace 21, and the induction coil 22 is connected to the power supply line 23. The insulating furnace 21 and the casing 1 are provided with a plurality of insertion holes 24, and heating rods 25 are provided in the insertion holes 24.

[0048] The switch structure 4 includes a switch sleeve 41, which passes through and is installed in the center of the heat conducting plate 26. A temperature control sleeve 42 is slidably connected inside the switch sleeve 41. A compression elastic member 2 43 is provided between the switch sleeve 41 and the temperature control sleeve 42. A temperature sensing magnet 44 is fixed on the top of the temperature control sleeve 42. A permanent magnetic slide cover 45 is slidably connected inside the temperature control sleeve 42.

The temperature sensing magnet 44 is connected to the power supply, and the permanent magnetic slide cover 45 is connected to the power supply line 23.

[0049] The working principle and beneficial effects of the above technical solution are as follows: when the carbon dioxide cylinder is placed on the heating assembly 2, the carbon dioxide cylinder presses down the heat conducting plate 26 and the switch structure 4 on the heat conducting plate 26 under the action of gravity, and the heat conducting plate 26 drives the telescopic rod 31 and the heating rod 25 on the heat insulating pad 32 to descend, and the telescopic rod 31 slides along the lifting sleeve 33 and squeezes the compression elastic member 1 34, and the heating rod 25 descends along the insertion hole 24 until the heating rod 25 descends into the induction coil 22, and at the same time, the temperature control sleeve 42 in the switch structure 4 is squeezed down by the carbon dioxide cylinder, and the compression elastic member 2 43 is compressed synchronously. During the descent of the temperature control sleeve 42, the adjusting top cover 47 contacts with the permanent magnetic slide cover 45, and under the squeezing of the adjusting top cover 47, the permanent magnetic slide cover 45 slides in the temperature control sleeve 42 and squeezes the compression elastic member 3 46. When the permanent magnetic slide cover 4 After reaching the top of the stroke, due to the enhanced magnetism of the temperature-sensitive magnet 44 at low temperature, the temperature-sensitive magnet 44 and the permanent magnetic slide cover 45 are attracted under the action of magnetic force, and the compression elastic member 3 46 is compressed to the shortest, the power supply on the temperature-sensitive magnet 44 is connected to the power supply line 23 on the permanent magnetic slide cover 45, the induction coil 22 is energized, the heating rod 25 is heated under the action of the induced current and the temperature is transferred to the heat-conducting disk 26 to heat the carbon dioxide cylinder, when the temperature of the carbon dioxide cylinder reaches the set value, the temperature-sensitive magnet 44 contacts the carbon dioxide cylinder to generate heat transfer, resulting in magnetic failure, the temperature-sensitive magnet 44 and the permanent magnetic slide cover 45 are separated under the action of the compression elastic member 3 46, when the temperature of the carbon dioxide cylinder drops to a certain temperature due to frosting, the magnetic force of the temperature-sensitive magnet 44 is restored, the temperature-sensitive magnet 44 and the permanent magnetic slide cover 45 are attracted again under the action of magnetic force, and the above steps are repeated;

[0050] The present invention utilizes the induction coil 22 and the heating rod 25 to heat the carbon dioxide cylinder. The design can generate heat through the induction principle, improves the heating efficiency, can achieve faster heating, and heats more evenly, avoiding uneven heat distribution. The design of the telescopic rod 31 and the lifting sleeve 33 can ensure that the heating rod 25 will only descend into the induction coil 22 for heating when the carbon dioxide cylinder is placed on the heat-conducting plate 26, which can ensure that the heating equipment will not heat in a no-load state. At the same time, the switch structure 4 utilizes the adsorption and separation of the temperature-sensitive magnet 44 and the permanent magnetic slide cover 45 to realize the opening and closing of the current of the heating component 2. The design can dynamically heat according to the temperature of the carbon dioxide cylinder, ensuring the stability of the internal pressure of the carbon dioxide cylinder during heating.

[0051] Example 3

[0052] On the basis of Example 1, the placement component 5 includes a support column 51, which is symmetrically bolted to the casing 1.

A lifting groove 55 is provided between the two side rods 54. The two side rods 54 are connected to the lifting groove 55 through a plurality of semicircular hoops 56. A handle 57 is installed on the two side rods 54. A hook 58 is rotatably connected to the slide 52. The hook 58 cooperates with the slide rod 53. A pin 59 is provided above the hook 58. The pin 59 is slidably connected in the shaft sleeve 510. The shaft sleeve 510 is fixed on the slide 52. A lifting structure 6 is provided at the bottom of the side rod 54.

[0053] The lifting structure 6 includes a bottom ring frame 61, which is installed on a lifting plate 62. The lifting plate 62 is threadedly connected to a lifting screw 63. The lifting screw 63 passes through and is rotatably connected in the lifting slot 55. A rotating gear 64 is installed at one end of the lifting screw 63. The two sides of the rotating gear 64 are respectively meshed with a lifting gear 1 65 and a lifting gear 2 66. The lifting gear 1 65 and the lifting gear 2 66 are both arranged on a rotating shaft 67. A ratchet structure is arranged between the rotating shaft 67 and the lifting gear 1 65 and the lifting gear 2 66. A driving mechanism 7 is respectively arranged at the left and right ends of the rotating shaft 67.

[0054] The driving mechanism 7 includes an open box plate 71, and the two open box plates 71 are respectively fixedly connected to the two sides of the lifting groove 55. A lifting pedal 72 and a lowering pedal 73 are rotatably connected in the open box plates 71.

The lifting pedal 72 and the lowering pedal 73 are respectively keyed to the two ends of the rotating shaft 67.

[0055] The beneficial effects of the above technical solution are as follows: when it is necessary to place a carbon dioxide cylinder for heating, the carbon dioxide cylinder is placed in front of the placement component 5, the operator pulls out the pin shaft 59 and then rotates the hook 58 to push the handle 57 to make the slide bar 53 slide along the slideway 52, thereby driving the side rod 54 and the lifting groove 55 to move forward until the slide bar 53 reaches the end of the slideway 52, and then steps on the descending pedal 73 to make the descending pedal 73 drive the rotating shaft 67 to rotate, and the rotation of the rotating shaft 67 then drives the lifting gear 2 66 to rotate through the ratchet structure. Due to the characteristics of the ratchet structure, the rotating shaft 67 idles on the lifting gear 1 65, and the lifting gear 2 66 meshes with the rotating gear 64 for transmission, and the rotating gear 64 drives the lifting screw 63 to rotate in the lifting groove 55, and the lifting plate 62 on the lifting screw 63 drives the bottom ring frame 61 to descend to the ground, and then after the carbon dioxide cylinder is moved into the bottom ring frame 61, it is lifted by the movable hoop 511.

Due to the characteristics of the ratchet structure, the rotating shaft 67 idles on the lifting gear 2 66, and the lifting gear 1 65 is meshed with the rotating gear 64 for transmission. The rotating gear 64 drives the lifting screw 63 to rotate in the lifting slot 55, and the lifting plate 62 on the lifting screw 63 drives the bottom ring frame 61 to rise, and the carbon dioxide cylinder rises with it, and then the handle 54 is pulled to make the slide bar 53 slide and reset in the slideway 52, and the side rod 54, the lifting slot 55 and the carbon dioxide cylinder are moved together above the heat conduction plate 26, and then the descending pedal 73 is stepped on to repeat the above arrangement until the carbon dioxide cylinder falls on the heat conduction plate 26. After the hook 58 is reset, the pin 59 is reset, so that the slide bar 53 is locked;

[0056] The present invention utilizes the slide bar 53 and the slideway 52 to realize the horizontal displacement of the side rod 54, the lifting groove 55 and the carbon dioxide cylinder. This design can reduce the difficulty of the operator to move the carbon dioxide cylinder, and the design of the hook 58 and the pin shaft 59 can lock the slide bar 53 in the slideway 52 when the carbon dioxide cylinder is placed above the heat conduction plate 26 to prevent the carbon dioxide cylinder from moving. At the same time, the lifting pedal 72 and the lowering pedal 73 drive the rotating shaft 67 to drive the lifting gear 1 65 and the lifting gear 2 66 to rotate, and then drive the rotating gear 64 to drive the lifting plate 62 and the carbon dioxide cylinder on the lifting screw 63 to lift and lower, wherein the design of the ratchet structure between the lifting gear 1 65 and the lifting gear 2 66 and the rotating shaft 67 ensures that the lifting pedal 72 and the lowering pedal 73 do not interfere with each other when they drive the rotating shaft 67 respectively. The overall design of the lifting structure 6 reduces the labor intensity of the operator when lifting the carbon dioxide cylinder or the cumbersomeness of the operation of additional equipment, and reduces the storage space for storing the carbon dioxide cylinder by fixing the carbon dioxide cylinder.

When carbon dioxide is found to leak through monitoring, it is determined whether it is necessary to pump the environment around the carbon dioxide cylinder according to the leakage of carbon dioxide, so as to avoid certain safety accidents caused by high carbon dioxide concentration;
