Description

Technical Field

[0001] The utility model relates to the technical field of liquid heaters, in particular to a high-efficiency, corrosion-resistant and temperature-controllable liquid heater. Background Art

[0002] A liquid heater is a device specifically used to heat liquids. It is based on the principle of heat transfer and transfers heat to the liquid through conduction, convection and radiation to increase its temperature. In a liquid heater, the heating source is usually an electric heater or a burner. The electric heater converts electrical energy into thermal energy to increase its surface temperature, and then transfers the heat to the liquid. The burner burns fuel to generate a high-temperature flame, thereby transferring heat to the liquid. Most existing liquid heaters use electric heating or steam heating to increase the liquid temperature to the required temperature. In this process, the heater may not be able to accurately control the temperature of the liquid, which may cause the liquid temperature to be too high or too low, thereby affecting the quality of the product and the stability of the production process. Utility Model Content

Therefore, this application proposes an efficient, corrosion-resistant, temperature-controllable liquid heater to solve the above problems.

[0004] The technical solution of the utility model is: a high-efficiency, corrosion-resistant and temperature-controllable liquid heater, comprising a protective shell, a connecting round cover and an L-shaped telescopic sleeve; a connecting round cover is provided above the protective shell for facilitating the protective shell to protect the liquid heater, an L-shaped telescopic sleeve is provided above the connecting round cover for adjusting according to the placement position of the liquid heater and driving the liquid heater to limit its position along the edge of the placement position to avoid it moving around in the liquid, an outer sleeve of the protective shell is provided with a corrosion-resistant outer shell body for preventing the liquid from corroding the protective shell and affecting its performance during long-term use, a heating coil is installed in the middle of the lower end of the connecting round cover, and an insulating coil sleeve is provided on the outer sleeve of the heating coil.

[0006] Preferably, a second circular hole for dissipating heat and allowing water to flow through is provided on the high temperature resistant inner shell body corresponding to the first circular hole, and a third circular hole for dissipating heat and allowing water to flow through is provided on the corrosion resistant outer shell body corresponding to the first circular hole.

[0008] Preferably, a temperature controller is installed at one end of the wire away from the round cover, a plug is installed at the lower end of the temperature controller, and the temperature sensor is electrically connected to the temperature controller. Through the action of the temperature controller, when the temperature of the liquid reaches a preset temperature, the temperature controller will cut off the power supply to stop heating.

[0009] Preferably, a first telescopic rod is sleeved inside one end of the L-shaped telescopic sleeve close to the connection round cover, and first pins are symmetrically provided on both sides of the connection between the first telescopic rod and the L-shaped telescopic sleeve, and multiple groups of first positioning holes for the first pins to pass through are linearly symmetrically provided on both sides of the first telescopic rod.

[0010] Preferably, a second telescopic rod is sleeved inside the end of the L-shaped telescopic sleeve away from the first telescopic rod, second pins are symmetrically provided on both sides of the connection between the second telescopic rod and the L-shaped telescopic sleeve, multiple groups of second positioning holes for the second pins to pass through are symmetrically provided on both sides of the second telescopic rod, and a fitting rod is installed at the end of the second telescopic rod away from the L-shaped telescopic sleeve, and a rubber pad for increasing friction is installed on the inner side of the fitting rod.

[0011] Beneficial effects of the utility model:

[0012] 1. After the heating coil is assembled, according to the depth of the container where the liquid to be heated is placed, the first telescopic rod is moved to a suitable height along the L-shaped telescopic sleeve by adjusting the first latch. After confirming that the height is correct, the first latch passes through the L-shaped telescopic sleeve and is positioned and connected to the first telescopic rod through the first positioning hole. Then, according to the width of the edge of the container, the second telescopic rod is moved horizontally along the L-shaped telescopic sleeve to a suitable width by adjusting the second latch, so that the fitting rod drives the rubber cushion to continuously approach the outside of the fitting container, and then the second latch passes through the L-shaped telescopic sleeve and is positioned and connected to the second telescopic rod through the second positioning hole. In this way, the hooking is completed, so that the heating coil will not move around in the liquid; when the hooking is completed, the heating coil goes deep into the liquid so that the liquid covers the heating coil, and then the plug is connected to the power supply, so that the current is transmitted along the wire to the heating coil, causing it to begin to emit heat. In this process, the insulating coil cover can prevent current leakage and protect the heating coil from moisture and corrosion. At the same time, through the action of the temperature sensor, you can know in real time how high the temperature of the liquid is heated to, and then through the action of the temperature controller, when the liquid temperature reaches the preset temperature, the temperature controller will cut off the power supply to stop heating.

[0013] 2. During the operation of the heating coil, heat is dissipated through the first circular hole, the second circular hole and the third circular hole, and the liquid continuously passes through the first circular hole, the second circular hole and the third circular hole for heating treatment. During this process, the high temperature resistant inner shell can protect the heating coil to avoid damage from high temperature, thereby extending the service life of the heat exchanger. At the same time, the high temperature resistant inner shell usually has good thermal conductivity, which can quickly transfer the heat generated by the heating coil to the liquid, thereby improving the heating efficiency. The anti-corrosion outer shell can prevent the protective shell from reacting with the chemical substances in the liquid during the heating process, causing corrosion and oxidation, thereby improving the protective performance of the protective shell.

[0022] See also Figure 4In this embodiment, a first telescopic rod 301 is sleeved inside the end of the L-shaped telescopic sleeve 3 close to the connection round cover 2, first latches 302 are symmetrically provided on both sides of the connection between the first telescopic rod 301 and the L-shaped telescopic sleeve 3, and multiple groups of first positioning holes 303 for the first latches 302 to pass through are linearly symmetrically provided on both sides of the first telescopic rod 301, a second telescopic rod 304 is sleeved inside the end of the L-shaped telescopic sleeve 3 away from the first telescopic rod 301, second latches 305 are symmetrically provided on both sides of the connection between the second telescopic rod 304 and the L-shaped telescopic sleeve 3, multiple groups of second positioning holes 306 for the second latches 305 to pass through are transversely symmetrically provided on both sides of the second telescopic rod 304, and a fitting rod 307 is installed at the end of the second telescopic rod 304 away from the L-shaped telescopic sleeve 3, and a rubber cushion 308 for increasing friction is installed on the inner side of the fitting rod 307.

In this process, the circular sealing ring 204 can increase the sealing performance, and prevent the protective shell 1 from slipping off during the use of the heating coil 201, thereby improving the safety of the heating coil 201;

[0024] After the heating coil 201 is assembled, the first telescopic rod 301 is moved to a suitable height along the L-shaped telescopic sleeve 3 through the adjustment of the first latch 302 according to the depth of the container in which the liquid to be heated is placed.
