Corrosion-resistant electric heating mantle Technical Field

[0001] This utility model relates to the field of electric heating jackets, and specifically to an electric heating jacket that prevents corrosion. Background Technology

[0002] Electric heating mantles are very convenient and practical for directly heating various spherical flasks and other vessels in chemical experiments. A search revealed existing technology (application number: CN201920640216.2), which describes that "a temperature sensor 2 is installed on the top of the heating mantle body 1, and a high-temperature resistant wire 5 is connected to the outside of the temperature sensor 2 to conduct current. A thermocouple 3 is installed inside the temperature sensor 2, and a temperature controller 2 controls the temperature inside the heating mantle by sensing the temperature through the thermocouple 3. A power connection wire 4 is provided on the right side of the thermocouple 3 for connecting to a power source." However, in existing technology, the power connection wire of the electric heating mantle is susceptible to corrosion from spilled liquid, which can affect power transmission. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a corrosion-resistant electric heating jacket is provided to solve the problem that the power connection wire of the electric heating jacket is easily affected by the corrosion of spilled liquid, thus affecting the power transmission.

[0004] To achieve the above objectives, a corrosion-resistant electric heating jacket is provided, comprising: a heating base, a heating chamber sleeve, and a flask, wherein the heating base and the heating chamber sleeve are fitted to the lower end and outer surface of the flask.

[0005] The upper end of the heating chamber sleeve is screwed with an adjusting stud through a fixing plate. The adjusting stud is connected to a hydraulic block through a connecting plate. The hydraulic blocks are symmetrically pressed onto the outer surface of the flask. A liquid guiding cavity is provided at the upper end of the hydraulic block. An absorbent cotton block is bonded to the inner groove surface of the hydraulic block. A liquid storage bottle is screwed to the hydraulic block through an mounting ring.

[0006] Furthermore, a temperature controller is fixed to the front surface of the heating base and the heating chamber sleeve, and the heating chamber sleeve is inserted into the upper surface of the heating base; and the heating chamber sleeve is fitted onto the surface of the flask.

[0007] Furthermore, the heating base and the inner side of the heating chamber are provided with a heat insulation layer; and the heat insulation layer is made of glass fiber insulation material, and the heating layer is attached to the inner side of the heat insulation layer.

[0008] Furthermore, the heating layer contains a heating wire and a temperature sensor; the temperature sensor is embedded and fixed in the heating layer, and a contact layer is attached to the inner side of the heating layer.

[0009] Furthermore, a sealing gasket is glued to the upper surface of the heating chamber sleeve, and a flask is sleeved inside the sealing gasket; and a hydraulic block is attached to the upper end.

[0010] Furthermore, the liquid guiding cavity is a semi-annular groove; and the lower cavity surface is high at the front and back and bottom in the middle, and a drain outlet is opened on the lower cavity surface of the liquid guiding cavity; and a liquid storage bottle is provided at the lower end of the drain outlet.

[0011] Furthermore, the hydraulic block, the liquid guiding cavity, the absorbent cotton block, and the liquid storage bottle constitute the corrosion-resistant structure of the heating base and the heating chamber sleeve, and the absorbent cotton block is made of polypropylene absorbent material.

[0012] The beneficial effects of this utility model are that the electric heating jacket, which effectively avoids liquid corrosion, uses a hydraulic block to press tightly against the surface of the flask, allowing the corrosive liquid overflowing from the heating to flow into the storage bottle through the liquid guiding cavity. The small amount of corrosive liquid flowing down the bottle surface is absorbed by the absorbent cotton block, which effectively prevents the corrosive liquid from dripping onto the surface of the electric heating jacket and the power cord. It also facilitates the collection and cleaning of the corrosive liquid, prevents the corrosive liquid from coming into contact with the electric heating jacket, and greatly reduces the probability of the electric heating jacket being corroded by the liquid.

An absorbent cotton block 4 is bonded to the inner surface of the hydraulic block 3. The hydraulic block 3 is screwed with a liquid storage bottle 5 via an mounting ring 34.

[0021] Working principle: When the flask 6 is heated using the heating base 1 and heating chamber sleeve 2, liquid overflow occurs. The overflowing corrosive liquid flows into the liquid guiding chamber 33 of the hydraulic block 3. It then flows into the storage bottle 5 through the drain groove 35 on the surface of the liquid guiding chamber 33. A small amount of corrosive liquid flowing down the bottle surface is absorbed by the absorbent cotton block 4 on the inner side of the hydraulic block 3, which effectively prevents corrosive liquid from dripping onto the surface of the electric heating sleeve and the power cord, and prevents the corrosive liquid from contacting the electric heating sleeve.

[0022] In this embodiment, a temperature controller 11 is fixed on the front surface of the heating base 1 and the heating chamber sleeve 2, and the heating chamber sleeve 2 is inserted into the upper surface of the heating base 1; and the heating chamber sleeve 2 is sleeved on the surface of the flask 6.

[0026] In this embodiment, the heating layer 24 contains a heating wire and a temperature sensor; the temperature sensor is embedded and fixed in the heating layer 24, and a contact layer 25 is attached to the inner side of the heating layer 24.

[0027] In a preferred embodiment, the heating wires are evenly distributed within the heating layer 24, which facilitates uniform heating of the flask 6 after power is applied, and the temperature sensor facilitates the detection of temperature changes during heating of the flask.

[0028] In this embodiment, a sealing gasket 22 is glued to the upper surface of the heating chamber sleeve 2, and a flask 6 is sleeved inside the sealing gasket 22; and a hydraulic block 3 is attached to the upper end.

[0029] As a preferred embodiment, the sealing gasket 22 further prevents corrosive liquid from flowing into the inner surface of the heating jacket. An absorbent cotton block 4 is provided at the upper end of the sealing gasket 22 to absorb any spilled corrosive liquid.

[0030] In this embodiment, the liquid guiding cavity 33 is a semi-annular groove; and the lower cavity surface is high at the front and back and bottom in the middle. A drain outlet 35 is opened on the lower cavity surface of the liquid guiding cavity 33; and a liquid storage bottle 5 is provided at the lower end of the drain outlet 35.

[0031] As a preferred embodiment, the liquid guiding cavity 33 gathers the overflowing corrosive liquid towards the center, allowing the overflowing corrosive liquid to flow into the storage bottle 5 through the drain outlet 35, making it convenient and easy to collect and clean the corrosive liquid.
