Description

Technical Field

[0001] This invention relates to the field of heating furnace technology, specifically a dual-chamber circulating heating furnace. Background Technology

[0002] Electric heating thermal oil furnaces are a new type of safe, efficient, and energy-saving special industrial furnace that provides high-temperature heat energy at low pressure (atmospheric or lower). Using thermal oil as the heat carrier, a hot oil pump circulates the heat carrier, transferring heat to the heat-using equipment. The electric heating thermal oil system consists of an explosion-proof electric heater, an organic heat carrier furnace, a heat exchanger (if applicable), an explosion-proof control box, a hot oil pump, an expansion tank, etc., all assembled in a skid. Users only need to connect the power supply, the inlet and outlet pipes for the medium, and some electrical interfaces to use it. In electric heating oil furnaces, heat is generated and transferred by electric heating elements immersed in thermal oil. Using thermal oil as the medium, a circulating pump forces the thermal oil to circulate in a liquid phase, transferring heat to one or more heat-using devices. After unloading from the heat-using equipment, the heat is returned to the heater through the circulating pump, absorbing heat again and transferring it to the heat-using equipment. This cycle repeats continuously, achieving continuous heat transfer and raising the temperature of the heated object to meet the heating process requirements.

[0003] There are two types of existing industrial heating furnaces: one is the flame furnace (or fuel furnace), which uses the heat from the combustion of solid, liquid or gaseous fuels in the furnace for heating; the other is the electric furnace, which converts electrical energy into heat in the furnace. Existing heating furnaces have slow heating and low safety factor. Therefore, a dual-cavity circulating heating furnace is designed to accelerate heating and improve work efficiency while ensuring safety. Summary of the Invention

[0005] A primary heating device, comprising a first power supply module, wherein the primary heating device is configured to preheat the water flow, the first power supply module is fixedly connected to the upper surface of the panel, the output end of the first power supply module is fixedly connected to a wire, and the end of the wire away from the first power supply module is fixedly connected to a first heating plate;

[0006] The bottom limiting device includes a second support frame and a first pressing block. A second fixing plate is fixedly connected to the upper surface of the second support frame. The bottom limiting device can limit the secondary heating device so that when the secondary heating device moves up and down in the second water tank, the device will not stop working due to excessive movement.

[0007] The secondary heating device includes a heating tube and a track plate. By setting up the secondary heating device, the liquid heated by the primary heating device can be rapidly heated to a boiling state. The track plate is set on the upper surface of the bottom limiting device, and the heating tube is fixedly connected to the upper surface of the track plate. A fourth support frame is fixedly connected to the top of the inner wall of the heating tube. A second servo motor is fixedly connected to the end of the fourth support frame. A rotating column is fixedly connected to the output end of the second servo motor. In use, the operator connects the second servo motor to the power supply and turns on the switch of the second servo motor. The second servo motor starts to work, thereby driving the rotating column and the second heating plate to move.

[0008] Preferably, a third support frame is fixedly connected to the outer surface of the first power supply module, and a third fixing plate is fixedly connected to the end of the third support frame away from the first power supply module. A protective cover is fixedly connected to the outer surface of the third fixing plate, and the first heating plate is disposed on the upper surface of the third fixing plate. The arrangement of the third fixing plate and the protective cover not only provides a certain protective effect for the device and prevents burns caused by accidental contact with the first heating plate, but also allows most of the heat generated by the first heating plate to come into contact with the outer surface of the first water tank, thereby improving the initial heating effect of the liquid in the first water tank.

[0009] Preferably, the primary heating device includes a first water tank, which is positioned directly above the first heating plate. A connecting pipe is fixedly connected to the inner circumference of the first water tank, and the connecting pipe passes through a second water tank. The connecting pipe allows water that has been preliminarily heated by the first heating plate to enter the inner cavity of the second water tank through the connecting pipe, thereby cooperating with the secondary heating device to achieve the effect of boiling the water. A water inlet pipe is fixedly connected to the upper surface of the first water tank, and the water inlet pipe passes through the first water tank. The water inlet pipe can replenish the liquid in the first water tank.

The first pressing block is fixedly connected to the lower surface of the track plate. The first pressing block and the first pressing strip are pressed and matched. When the secondary heating device moves up and down in the inner cavity of the second water tank under the influence of steam, the track plate will move downward, thereby driving the first pressing block to press against the first pressing strip and the elastic frame, thus playing a certain buffering effect on the secondary heating device.

[0011] Preferably, a side stabilizing device is provided between the heating tube and the inner wall of the second water tank. By providing the side stabilizing device, when the secondary heating device moves up and down in the inner cavity of the second water tank under the influence of steam, it can cooperate with the bottom limiting device to achieve the stabilization and return effect of the secondary heating device.

A first spring is fixedly connected to the upper surface of the limiting ring. The end of the first spring is fixedly connected to the outer surface of the sliding plate. The arrangement of the first spring, the sliding plate and the limiting ring can make the sliding plate always slide on the outer surface of the heating tube.

[0013] Preferably, a fifth fixed plate is fixedly connected to the side of the fifth support frame away from the sliding plate, an elastic strip is fixedly connected to the end of the fifth fixed plate, and a second pressing block is fixedly connected to the end of the elastic strip. The second pressing block and the second pressing strip are pressed and adapted to each other. The elastic strip can store elastic potential energy during the pressing process of the second pressing block and the second pressing strip, so that the secondary heating device can rebound to its original position after the secondary heating device stabilizes.

[0014] Preferably, a sixth support frame is fixedly connected to the outer surface of the rotating column, and a second heating plate is fixedly connected to the end of the sixth support frame away from the rotating column. The second heating plate is connected to the output end of the second servo motor. The setting of the second heating plate can further heat the liquid in the inner cavity of the second water tank, thereby making the water boil. The rotating second heating plate can make the heat on the outer surface of the heating tube more uniform, thereby making the water in the inner cavity of the second water tank boil more uniformly.

[0015] Preferably, a connecting rod is fixedly connected to the end of the rotating column away from the second servo motor, and a limit block is fixedly connected to the end of the connecting rod away from the rotating column.

A support column is fixedly connected to the lower surface of the rotating block, and a second spring is fixedly connected to the bottom end of the support column. A stirring plate is fixedly connected to the end of the second spring. The setting of the second spring and the stirring plate can drive the stirring plate to stir the water flow in the inner cavity of the second water tank when the secondary heating device moves up and down in the inner cavity of the second water tank under the influence of steam, thereby making the water flow heated more evenly.

[0016] Preferably, the top of the second water tank is fixedly connected to a steam outlet device. By setting the steam outlet device, the water vapor generated in the inner cavity of the second water tank can be collected, and the secondary heating device can move up and down in the inner cavity of the second water tank under the influence of steam. The steam outlet device includes a top pipe and a movable ring. The top pipe is fixedly connected to the upper surface of the second water tank, and a steam outlet is fixedly connected to the outer surface of the top pipe. The steam outlet passes through the top pipe.

[0017] This invention provides a dual-chamber circulating heating furnace. It has the following beneficial effects:

[0018] I. This dual-cavity circulating heater, through the primary heating device, can initially heat the water flow. The third fixing plate and protective cover not only provide a certain degree of protection to prevent burns caused by accidental contact with the primary heating plate, but also ensure that most of the heat generated by the primary heating plate comes into contact with the outer surface of the primary water tank, thereby improving the initial heating effect of the liquid in the primary water tank. The connecting pipe allows the water, after being initially heated by the primary heating plate, to enter the inner cavity of the secondary water tank, thus cooperating with the secondary heating device to achieve the effect of boiling the water flow. The inlet pipe can replenish the liquid in the primary water tank.

[0019] Second, this dual-cavity circulating heating furnace, through the setting of the bottom limiting device, can limit the secondary heating device, so that when the secondary heating device moves up and down in the second water tank, the device will not stop working due to excessive movement. When the secondary heating device moves up and down in the inner cavity of the second water tank under the influence of steam, the track plate will move downward, thereby driving the first extrusion block to press against the first extrusion strip and the elastic frame, thus playing a certain buffering role for the secondary heating device.

[0020] Third, this dual-cavity circulating heater, by setting a side stabilizing device, can cooperate with the bottom limiting device to stabilize and return the secondary heating device when it moves up and down in the inner cavity of the second water tank under the influence of steam. The setting of the second extrusion strip can cooperate with the second extrusion block to achieve the limiting and stabilizing effect of the secondary heating device. The setting of the first spring, sliding plate and limiting ring can make the sliding plate always slide on the outer surface of the heating tube. The setting of the elastic strip can store elastic potential energy during the extrusion process of the second extrusion block and the second extrusion strip, so that the secondary heating device can spring back to its original position after stabilization.

[0021] Fourth, this dual-cavity circulating heater, by setting a secondary heating device, can rapidly heat the liquid after it has been heated by the primary heating device until it boils. The setting of the second heating plate can further heat the liquid in the inner cavity of the second water tank, thereby making the water boil. The rotating second heating plate can make the heat on the outer surface of the heating tube more uniform, thereby making the water in the inner cavity of the second water tank boil more uniformly.

[0022] V. This dual-chamber circulating heater, by setting up an exhaust device, can collect the water vapor generated in the inner cavity of the second water tank. At the same time, it can cause the secondary heating device to move up and down in the inner cavity of the second water tank under the influence of steam. When the water vapor in the inner cavity of the second water tank reaches a certain amount, the water vapor will push the movable ring, causing the movable ring to move upward. When the movable ring moves upward, the sealing ring is no longer squeezed against the exhaust port, so that the water vapor in the inner cavity of the second water tank is discharged from the exhaust port and the collection pipe. When the water vapor in the inner cavity of the second water tank decreases, the air pressure decreases, the second movable ring moves downward, and the sealing ring blocks the exhaust port again, thus performing reciprocating operation.

The first power supply module 44 starts to work, driving the first heating plate 48 to start working, thereby completing the initial heating of the water flow in the first water tank 41.

[0036] Bottom limiting device 6, the bottom limiting device 6 includes a second support frame 61 and a first pressing block 65.

[0037] The secondary heating device 8 includes a heating tube 801 and a track plate 802. By setting the secondary heating device 8, the liquid heated by the primary heating device 4 can be rapidly heated to a boiling state.

A rotating column 805 is fixedly connected to the output end of the second servo motor 804. In use, the operator connects the second servo motor 804 to the power supply and turns on the switch of the second servo motor 804. The second servo motor 804 starts to work, thereby driving the rotating column 805 and the second heating plate 807 to move.

[0038] A third support frame 45 is fixedly connected to the outer surface of the first power supply module 44. A third fixing plate 46 is fixedly connected to the end of the third support frame 45 away from the first power supply module 44.

The arrangement of the third fixing plate 46 and the protective cover 49 not only provides a certain protective effect for the device and prevents burns caused by accidental contact with the first heating plate 48, but also allows most of the heat generated by the first heating plate 48 to contact the outer surface of the first water tank 41, thereby improving the initial heating effect of the liquid in the first water tank 41.

[0039] The primary heating device 4 includes a first water tank 41, which is positioned directly above the first heating plate 48. A connecting pipe 42 is fixedly connected to the inner circumference of the first water tank 41, and the connecting pipe 42 passes through the second water tank 5.

The first extrusion block 65 is fixedly connected to the lower surface of the track plate 802. The first extrusion block 65 and the first extrusion strip 64 are squeezed and adapted to each other. When the secondary heating device 8 moves up and down in the inner cavity of the second water tank 5 under the influence of steam, the track plate 802 will move downward, thereby driving the first extrusion block 65 to squeeze the first extrusion strip 64 and the elastic frame 63, thereby playing a certain buffering effect on the secondary heating device 8.

[0041] A side stabilizing device 7 is provided between the heating tube 801 and the inner wall of the second water tank 5. By providing the side stabilizing device 7, when the secondary heating device 8 moves up and down in the inner cavity of the second water tank 5 under the influence of steam, it cooperates with the bottom limiting device 6 to complete the stabilization and return effect of the secondary heating device 8.

The second extrusion strip 72 can cooperate with the second extrusion block 79 to achieve the limiting and stabilizing effect on the secondary heating device 8. The upper surface of the limiting ring 73 is fixedly connected to a first spring piece 74. The end of the first spring piece 74 is fixedly connected to the outer surface of the sliding plate 75. The arrangement of the first spring piece 74, the sliding plate 75 and the limiting ring 73 can make the sliding plate 75 always slide on the outer surface of the heating tube 801.

[0044] The third embodiment, such as Figures 7-9 As shown, a sixth support frame 806 is fixedly connected to the outer surface of the rotating column 805. A second heating plate 807 is fixedly connected to the end of the sixth support frame 806 away from the rotating column 805.

[0045] A connecting rod 808 is fixedly connected to one end of the rotating column 805 away from the second servo motor 804. A limit block 809 is fixedly connected to one end of the connecting rod 808 away from the rotating column 805.

A stirring plate 813 is fixedly connected to the end of the second spring plate 812. The setting of the second spring plate 812 and the stirring plate 813 allows the second heating device 8 to move up and down in the inner cavity of the second water tank 5 under the influence of steam, thereby driving the stirring plate 813 to stir the water flow in the inner cavity of the second water tank 5, so that the water flow is heated more evenly.

[0046] The top of the second water tank 5 is fixedly connected to a steam outlet 9. By setting the steam outlet 9, the water vapor generated in the inner cavity of the second water tank 5 can be collected, and the secondary heating device 8 can move up and down in the inner cavity of the second water tank 5 under the influence of steam. The steam outlet 9 includes a top pipe 91 and a movable ring 92. The top pipe 91 is fixedly connected to the upper surface of the second water tank 5, and the outer surface of the top pipe 91 is fixedly connected to a steam outlet 94, which penetrates the top pipe 91.

A sealing ring 93 is fixedly connected to the outer surface of the movable ring 92. The sealing ring 93 is squeezed and adapted to the outlet 94 provided on the inner wall of the top pipe 91. When the water vapor in the inner cavity of the second water tank 5 reaches a certain amount, the water vapor will push the movable ring 92, causing the movable ring 92 to move upward. When the movable ring 92 moves upward, the sealing ring 93 no longer squeezes the outlet 94, so that the water vapor in the inner cavity of the second water tank 5 is discharged from the device through the outlet 94 and the collection pipe 95. When the water vapor in the inner cavity of the second water tank 5 decreases, the air pressure decreases, the second movable ring 92 moves downward, and the sealing ring 93 blocks the outlet 94 again, thus performing a reciprocating operation.
