Description

Technical Field

[0001] The utility model belongs to the field of electromagnetic heating, in particular to an energy-saving explosion-proof electromagnetic heater. Background Art

[0002] Electromagnetic heater is a device that converts electrical energy into thermal energy using the principle of electromagnetic induction. It generates heat by interacting the magnetic field generated by the current in the conductor with the molecular motion inside the heated object. Electromagnetic heaters are widely used in household, industrial, medical and other fields, such as induction cookers, electromagnetic water heaters, electromagnetic dryers, etc. They provide convenient and efficient heating solutions and effectively improve energy efficiency.

[0003] Among them, the main role is played by the heating coil, which generates an alternating electromagnetic field when energized, causing the molecules inside the heated object to vibrate and rub, thereby generating heat.

[0004] The heating coil is usually spirally wrapped around the outer circumference of the roller to heat the material inside the roller. There is also an outer roller on the outer circumference of the roller to prevent the coil from being exposed. This causes the heat of the coil to be transferred not only to the inner roller body, but also to the outer roller. For the staff, if they accidentally touch the outer roller, they can easily get burned. Utility Model Content

[0005] Technical problem to be solved: How to solve the problem of workers being easily injured due to overheating of the outer roller.

[0006] Technical solution: The utility model provides an energy-saving explosion-proof electromagnetic heater, including a main body structure and an improved structure: the main body structure includes a roller body, the outer peripheral side of the roller body is sleeved with a heating coil and an outer roller located outside the heating coil, and there is a certain distance between the outer roller and the heating coil; the improved structure includes a plurality of annular tubes sleeved on the outer peripheral side of the outer roller and evenly distributed along its length direction, and these annular tubes are connected by upper and lower staggered transverse tubes; in addition, one of the two outermost annular tubes is connected to a water outlet pipe, and the other is connected to a water inlet pipe, and the water inlet pipe can be connected to an external faucet through a water pump.

[0007] Furthermore, a water tank containing coolant can be arranged outside the heater, a water pump is built in the water tank, the output end of the water pump is connected to the water inlet pipe, and the liquid inlet end of the water tank is connected to the water outlet pipe.

[0008] Furthermore, the structure consisting of the annular tube and the transverse tube can be replaced by a spiral tube.

[0009] Furthermore, an outer tube having the same length as the roller body can be sleeved on the outer peripheral side of the annular tube, and the outer tube is penetrated by the water outlet pipe and the water inlet pipe.

[0010] Furthermore, an inner groove adapted to the annular tube and the transverse tube may be provided on the inner side of the outer tube so as to insert the annular tube and the transverse tube therein.

[0011] Furthermore, a layer of heat insulation pad may be provided between the heating coil and the outer roller to wrap the heating coil.

[0012] Technical effect: In the present invention, the annular tube and the transverse tube cooperate to form a pipeline structure that evenly covers the outer roller. This pipeline structure cools the outer roller by introducing water through the annular tube and the transverse tube through the outlet pipe and the inlet pipe, thereby avoiding the problem of overheating of the outer roller and easily scalding the staff.

[0020] The energy-saving explosion-proof electromagnetic heater provided in this specific embodiment is as follows: Figure 1, Figure 2 and Figure 3 As shown, it includes a main structure and an improved structure: the main structure includes a roller body 1, on the outer peripheral side of the roller body 1, a heating coil 2 and an outer roller 3 located outside the heating coil 2 are sleeved, and there is a certain distance between the outer roller 3 and the heating coil 2; the improved structure includes a plurality of annular tubes 4 sleeved on the outer peripheral side of the outer roller 3 and evenly distributed along its length direction, and these annular tubes 4 are connected with upper and lower offset transverse tubes 5; in addition, one of the two outermost annular tubes 4 is connected with a water outlet pipe 6, and the other is connected with a water inlet pipe 7, and the water inlet pipe 7 can be connected to an external faucet through a water pump. In this way, the annular tube 4 and the transverse tube 5 cooperate to form a pipeline structure that evenly covers the outer roller 3. This pipeline structure cools the outer roller 3 through the water outlet pipe 6 and the water inlet pipe 7 and introduces water flow through the annular tube 4 and the transverse tube 5 to avoid the problem that the outer roller 3 is overheated and easily burns the staff.

[0021] A water tank containing coolant can be arranged outside the heater, and a water pump is built inside the water tank. The output end of the water pump is connected to the water inlet pipe 7, and the liquid inlet end of the water tank is connected to the water outlet pipe 6. In this way, the coolant can be used to cool instead of water. In addition, the structure composed of the annular tube 4 and the horizontal tube 5 can be replaced by a spiral tube. As long as it evenly covers the outer ring of the outer roller 3.

[0022] The outer circumference of the annular tube 4 can be sleeved with an outer tube of the same length as the roller body 1, and the outer tube is penetrated by the water outlet pipe 6 and the water inlet pipe 7. In this way, the annular tube 4 and the transverse tube 5 are covered therein to protect them. In addition, in order to reduce the thickness of the overall structure, an inner groove adapted to the annular tube 4 and the transverse tube 5 can be provided on the inner side of the outer tube so that the annular tube 4 and the transverse tube 5 can be sleeved therein.

[0023] In addition to the above, a layer of heat insulation pad can be arranged between the heating coil 2 and the outer roller 3 to wrap the heating coil 2 therein, so as to reduce the amount of heat transferred to the outer roller 3. This cooperates with the cooling structure mentioned above, on the one hand, to reduce the heat transferred to the outer roller 3; on the other hand, to cool the outer roller 3. In this way, through the cooperation of the two, the temperature of the outer roller 3 can be effectively reduced, greatly reducing the possibility of scalding the staff due to the excessive temperature of the outer roller 3.
