Description

Technical Field

[0001] The utility model relates to a boiler, in particular to an electric heating vacuum boiler. Background Art

[0002] Since vacuum boilers operate at negative pressure, the negative pressure in this utility model refers to pressure lower than atmospheric pressure. The heat exchanger in vacuum boilers is used under pressure, which is very convenient and widely used. When in use, the electric heating rod can be used to heat the heat medium. The heated heat medium transfers heat to the heat exchange tube, which can heat the water in the heat exchange tube.

[0003] In the prior art: CN201520972586.8 New Vacuum Boiler, the utility model discloses a new vacuum boiler, which includes a vacuum boiler body, a front furnace door of the vacuum boiler body including an outer plate, an inner plate, a frame, and a burner pipe. The outer plate and the inner plate are sealed and connected at their periphery by the frame, and a furnace door vacuum chamber is formed between the outer plate, the inner plate, and the frame; a guide plate arranged from bottom to top is provided on the inner plate within the furnace door vacuum chamber; the burner pipe is sealed and passes through the outer plate and the inner plate in sequence to communicate with the combustion chamber of the vacuum boiler body. Advantages: The steam in the furnace door vacuum chamber circulates together with the steam in the vacuum chamber of the vacuum boiler body, which can promptly remove the heat absorbed by the inner plate and extend the service life of the front furnace door; the inner plate is adjacent to the vacuum boiler body as a hot zone, and the outer plate is away from the vacuum boiler body as a cold zone.

[0004] Although the guide plate in the prior art allows the steam in the hot zone to enter the cold zone during the rising process and mix with the steam in the cold zone, thereby increasing the heating rate of the steam in the vacuum chamber of the furnace door and thus improving the heat utilization rate, the vacuum boiler in the prior art is not conducive to the maintenance of the electric heating rod. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an electric heating vacuum boiler.

[0006] The utility model is implemented by the following technical solution: an electric heating vacuum boiler is provided with a heating chamber and a heat exchange chamber, a water inlet and outlet are provided on the top of the heat exchange chamber, the heating chamber and the heat exchange chamber are connected to each other, a heat exchange space is provided inside the heat exchange chamber, a heat exchange component is provided in the heat exchange chamber, the heat exchange component is a heat exchange tube, water to be heat exchanged is provided in the heat exchange tube, a heating component is provided in the heating chamber, the heating component is a heating rod, the heating rod is an electric heating rod, and a support and guide component is provided at the bottom of the electric heating rod.

[0007] The supporting guide component is a heating tube guide rail, on which an electric heating rod is arranged, and the heating tube guide rail provides support for the bottom of the electric heating rod.

[0008] A heating space is provided inside the heating chamber, and the heating space is filled with heating medium water, and the heating medium water is thermal medium water.

[0009] A fixing chuck is provided on one side of the electric heating rod, a round hole is provided on the fixing chuck, and the electric heating rod is inserted into the round hole.

[0010] The outer surface of the heating chamber is provided with a mounting flange, and a locking bolt for locking is provided between the mounting flange and the fixing chuck.

[0011] Compared with the existing technology, the present invention can use the electric heating rod to heat the heat medium water when in use. The heated heat medium water generates steam, and the steam rises into the heat exchange chamber, which can heat the heat exchange tubes arranged in the heat exchange chamber, so that the water inside the heat exchange tubes can be heated. At the same time, a heating tube guide rail is provided at the bottom of the electric heating rod. The heating tube guide rail can facilitate the replacement and maintenance of the electric heating rod, thereby facilitating the maintenance of the vacuum boiler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] An electric heating vacuum boiler is provided with a heating chamber 1 and a heat exchange chamber 2, a water inlet and outlet 3 is provided on the top of the heat exchange chamber 2, the heating chamber 1 and the heat exchange chamber 2 are connected to each other, a heat exchange space is provided inside the heat exchange chamber 2, a heat exchange component is provided in the heat exchange chamber, the heat exchange component is a heat exchange tube 4, water to be heat exchanged is provided in the heat exchange tube 4, a heating component is provided in the heating chamber 1, the heating component is a heating rod 5, the heating rod 5 is an electric heating rod, and a support guide component is provided at the bottom of the electric heating rod.

[0018] When the electric heating tube needs to be maintained, the vacuum boiler needs to be disassembled as a whole in the past. Such disassembly and maintenance costs are high and the operation is not very convenient. Now, the electric heating rod can be moved and replaced by using a supporting guide component. The supporting guide component is a heating tube guide rail 6. An electric heating rod is arranged on the heating tube guide rail 6. The heating tube guide rail provides support for the bottom of the electric heating rod.

The heating medium water 7 is made of heat medium water, and the heating medium water is heated by an electric heating rod. The steam generated by the heating will enter the heat exchange chamber, and the water in the heat exchange tube 4 in the heat exchange chamber 2 will be heated by the steam, so that hot water can be produced.

[0020] In order to further assemble and disassemble the electric heating rod, the bolts between the fixed chuck 8 and the assembly flange 9 are used for fixing. This makes it convenient to disassemble during later maintenance without disassembling the vacuum boiler as a whole. A fixed chuck 8 is provided on one side of the electric heating rod, and a circular hole is provided on the fixed chuck 8. The electric heating rod is inserted into the circular hole. An assembly flange 9 is provided on the outer surface of the heating chamber 1, and a locking bolt 10 for locking is provided between the assembly flange 9 and the fixed chuck 8.
