Description

TECHNICAL FIELD

[0001] The utility model relates to heating device technical field, concretely is a kind of carbon dioxide heating device. BACKGROUND

[0002] In industrial production, liquid carbon dioxide is often gasified by heating liquid carbon dioxide to absorb heat and gasify it.

[0003] The existing heating device generally adopts electric heating mode, and as the continuous gasification of carbon dioxide, the liquid carbon dioxide gradually decreases when heating, which can cause dry burning of the device, and can easily cause damage to the device. In related technologies, such as a liquid carbon dioxide electric heating device with the publication number CN218468806U, when the liquid level drops to a certain level, the floating block will also drop, driving the connecting rod to move and opening the sealing plug. Liquid carbon dioxide enters the shell from the liquid inlet pipe, which plays a replenishing role and avoids dry burning and prevents damage to the device. However, the device does not have an automatic pressure relief structure, and only detects the internal pressure of the device through a pressure gauge. The floating block at the bottom of the liquid inlet pipe also reduces the aperture of the liquid inlet pipe in contact with the liquid carbon dioxide, and the sliding design is more likely to cause impurities to be stuck in the liquid inlet pipe, causing blockage. When the liquid inlet pipe and the gas outlet pipe are blocked, the internal pressure of the device cannot be normally relieved, which poses a safety hazard. SUMMARY

[0030] In use, the operator passes the liquid carbon dioxide and the cooling liquid into the heating tank, heats the carbon dioxide through the electric heating pipe, and the generated gaseous carbon dioxide is discharged through the gas outlet pipe.

[0031] In the related art, such as the liquid carbon dioxide electric heating device disclosed in CN218468806U, when the liquid level drops to a certain extent, the floating block will also drop, driving the connecting rod to move, so that the sealing plug is opened, and the liquid carbon dioxide enters the shell from the liquid inlet pipe, playing a supplementing role, avoiding dry burning, and preventing damage to the device. However, the device does not have an automatic pressure relief structure, and only detects the internal pressure of the device through a pressure gauge. The floating block at the bottom of the liquid inlet pipe also reduces the aperture of the liquid inlet pipe in contact with the liquid carbon dioxide, and the sliding design is more likely to cause impurities to be stuck in the liquid inlet pipe, causing blockage. When the liquid inlet pipe and the gas outlet pipe are blocked, the internal pressure of the device cannot be normally relieved, which poses a safety hazard.

[0032] In order to solve the problems in the related art to some extent, the present application provides a carbon dioxide heating device. In use, when the liquid inlet pipe and the gas outlet pipe are blocked, causing the internal pressure of the heating tank 11 to be unable to be normally relieved, the pressure will upwardly drive the moving plate 21 to move to the pressure relief hole 23, and the pressure inside the heating tank 11 is discharged through the pressure relief hole 23 and sprayed to the liquid discharge ring 25. Since the high-pressure gas generated by heating has a certain temperature, when the gas is sprayed into the liquid discharge ring 25, a certain amount of condensed water will be generated. The condensed water will be collected in the liquid discharge ring 25, and the condensed water will be collected through the liquid discharge port 26 and the connected pipeline and the collection device, which is convenient and fast.

[0033] The present application will be described below in conjunction with the drawings and specific embodiments:

[0034] In combination Figures 1-4The embodiment of the application provides a carbon dioxide heating device, which comprises a heating tank 11, a top cover 12 is arranged on the top of the heating tank 11, a pressure relief assembly 2 is arranged in the top cover 12, the pressure relief assembly 2 comprises a moving plate 21 which is slidably connected to the inside of the top cover 12, a first guide rod 22 is slidably connected to the side of the moving plate 21, a spring is arranged on the outside of the first guide rod 22, a pressure relief hole 23 is arranged in the inside of the moving plate 21 and above the moving plate 21, a sealing ring 24 is fixedly connected to the bottom of the moving plate 21 and outside the moving plate 21, a liquid discharge ring 25 is arranged on the outside of the sealing ring 24 and the bottom of the moving plate 21, and a liquid discharge port 26 is fixedly connected to the bottom of the liquid discharge ring 25.

[0035] In use, liquid carbon dioxide and cooling liquid are introduced into the inside of the heating tank 11 through the liquid inlet pipe, then the electric heating pipe in the inside of the heating tank 11 is started to heat the liquid carbon dioxide, the generated carbon dioxide gas is transported out of the heating tank 11 through the gas outlet pipe, as the liquid carbon dioxide decreases, the floating block also descends to drive the connecting rod to move and make the sealing plug open, the liquid carbon dioxide enters the shell through the liquid inlet pipe to play a supplementing role and avoid dry burning, when the liquid inlet pipe and the gas outlet pipe are blocked and normal pressure relief of the inside of the heating tank 11 is caused, the pressure drives the moving plate 21 to move upwards to the pressure relief hole 23, at this moment, the high-pressure gas obtains an outlet and is discharged from the inside of the heating tank 11 through the pressure relief hole 23 and sprayed to the liquid discharge ring 25, as the high-pressure gas generated by heating has a certain temperature, the gas sprayed to the liquid discharge ring 25 generally has room temperature, when the gas is sprayed to the surface of the liquid discharge ring 25, condensate water is formed on the liquid discharge ring 25, the condensate water is gathered in the inside of the liquid discharge ring 25 and collected through the liquid discharge port 26 and the connected pipeline and the collecting device, so that the condensate water is conveniently and quickly collected.

[0038] In some embodiments, one side of the trigger slider 31 protrudes above the moving plate 21, and the protruding part is provided with an inclined surface, which facilitates pushing the trigger slider 31 when the moving plate 21 is moved upwards, thereby enhancing the reliability of the device.

[0040] In some embodiments, the alarm lamp 33 is internally provided with a storage battery, and the alarm lamp 33 is electrically connected to the storage battery, thereby ensuring the normal use of the alarm lamp 33.

[0041] In some embodiments, the top of the moving plate 21 is fixedly connected with a liquid adding pipe and an air outlet pipe, and the liquid adding pipe and the air outlet pipe are slidably connected to the top of the top cover 12, so that the liquid adding pipe and the air outlet pipe move together with the moving plate 21, thereby enhancing the sealing performance of the connection between the pipes and the moving plate 21.

[0042] In some embodiments, the pressure relief hole 23 is an L-shaped through hole, the top of the L-shaped through hole is arranged above the moving plate 21, and the bottom of the L-shaped through hole is arranged at the bottom of the top cover 12 and above the liquid discharge ring 25, thereby facilitating the discharge of high-pressure gas in the heating tank 11 into the inside of the liquid discharge ring 25.

[0043] In some embodiments, the number of the first guide rods 22 is four, and the positions of the first guide rods 22 are symmetric about the center of the moving plate 21, thereby enhancing the stability of the upward and downward movement of the moving plate 21.
