Description

Technical Field

[0001] The invention belongs to the field of Teflon electric heaters, in particular to an energy-saving explosion-proof Teflon electric heater. Background Art

[0002] Teflon electric heater is a device specially designed for heating liquids in corrosive environments. When traditional electric heaters are heated in corrosive liquids, the corrosive liquids will also cause damage to the electric heaters. Therefore, in order to adapt to this corrosive environment, Teflon electric heaters are designed.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figure 1-3As shown, an energy-saving explosion-proof Teflon electric heater according to an embodiment of the present invention comprises a flame-retardant junction box 1 and a fixed bracket 4 fixedly installed below the flame-retardant junction box 1, a heating component 6 is fixedly installed on the lower side of the fixed bracket 4, the heating component 6 and the fixed bracket 4 are in a vertical state, a temperature protection component 5 is fixedly installed inside the fixed bracket 4, a water level sensor 7 is installed at the vertical connection position between the fixed bracket 4 and the heating component 6, a waterproof connector 11 is installed on the side of the flame-retardant junction box 1, a UL flame-retardant corrugated hose 3 is connected to the side of the waterproof connector 11, and a circuit board overheating protection component 2 is installed on the outer side of the end of the UL flame-retardant corrugated hose 3;

[0038] The heating component 6 includes a heating L-shaped inner core 61, the outer side of the heating L-shaped inner core 61 is wrapped with a hose made of PTFE material, and the outer side of the fixed bracket 4 is also provided with a hose made of PTFE material. The heating L-shaped inner core 61 includes a stainless steel hollow tube 611 and a three-hole ceramic column 613 installed at the center of the stainless steel hollow tube 611, and a filling protective layer 612 is filled between the stainless steel hollow tube 611 and the three-hole ceramic column 613.

[0039] Specifically, after the heating component 6 is placed in the corrosive liquid, the wire connector inside the UL flame retardant corrugated hose 3 is connected to the external power supply. The UL flame retardant corrugated hose 3 is a flexible tube with flame retardant properties. It is used to protect cables or pipes and prevent physical damage. It also helps to dissipate heat and compensate for thermal expansion. The UL flame retardant corrugated hose 3 is set to protect the wires and cables connected to the external power supply. The waterproof connector 11 is used to ensure that the cable or pipe connection of the electric heater is waterproof to prevent moisture from entering the electric heater or its electrical system to avoid short circuit or corrosion. The flame retardant junction box 1 is mainly used to protect the electrical connection part of the electric heater, prevent electrical fires, and ensure the safety of the electrical system. The heating component 6 is powered by an external power supply to heat the corrosive liquid, and the temperature The protection component 5 will detect the temperature of the heating component 6 to perform overheating protection, and the circuit board overheating protection component 2 will monitor the temperature of the internal wires and cables to perform overheating protection. A three-hole ceramic column 613 is fixedly installed inside the stainless steel hollow tube 611. The existence of the three-hole ceramic column 613 can improve the structural stability and heat conduction efficiency of the heating component 6. The three-hole ceramic column 613 serves as a supporting structure to enhance the mechanical strength of the heating component 6 and prevent the heating component 6 from being deformed after long-term use. The high thermal resistance and good thermal conductivity of the three-hole ceramic column 613 help to evenly distribute heat and improve heating efficiency. The three-hole ceramic column 613 can also serve as an insulator to ensure electrical isolation between the heating component 6 and the PTFE material hose covering the outside, thereby increasing safety in use.

[0040] like Figure 1-4As shown, the temperature protection component 5 is internally integrated with a thermocouple detection module 51, an amplifier circuit 52, a Schmidt comparator 53, a photoelectric thyristor 54 and a relay 55. The thermocouple detection module 51, the amplifier circuit 52, the Schmidt comparator 53, the photoelectric thyristor 54 and the relay 55 are electrically connected in sequence, and the relay 55 is electrically connected to the electric heater.

[0041] Specifically, the thermocouple detection module 51 can detect the temperature of the heating component 6. When the temperature is within the operating temperature range, the output level of the thermocouple detection module 51 is relatively small. At this time, the signal is amplified by the amplifier circuit 52. When the amplified level is lower than the Schmidt comparator 53, the level will be triggered. At this time, the Schmidt comparator 53 outputs a low level, the photoelectric thyristor 54 is not conducting, and the relay 55 is in a normally on state, supplying power to the heater. At this time, the heater works normally. When the thermocouple detection module 51 detects that the temperature of the heating component 6 is higher than the operating temperature, because the thermocouple detection module 51 is installed in the middle position of the vertical part of the heating component 6, at this time, the lower end of the heating component 6 has water. As a medium, its lower end will be at the working temperature, and the position detected by the thermocouple detection module 51 is in the middle section of the heating component 6. If it is not in contact with water, the thermocouple detection module 51 will detect a higher temperature, which is higher than the working temperature. The thermocouple detection module 51 outputs a larger level, and the signal level amplified by the amplifier circuit 52 is greater than the Schmidt comparator 53 and then triggers the level. The output high level enables the photoelectric thyristor 54 to work, and the relay 55 disconnects the power supply, so that the heater no longer works, which plays an overheating protection role and avoids the life of the electric heater being shortened. The circuit board overheating protection component 2 also has the same principle, but the detection object is changed to wires and cables.

[0042] like Figure 5 As shown, the water level sensor 7 is electrically connected to the Schmidt comparator 53 . The water level sensor 7 is used to detect the water level of the heated liquid. The water level sensor 7 is wrapped by a shell made of PTFE material.

[0043] Specifically, the water level sensor 7 can detect the water level of the liquid. When the water level reaches the heating requirement, it outputs a low level. At this time, the Schmidt comparator 53 electrically connected to it outputs a low level, the photoelectric thyristor 54 is not conducting, and the relay 55 is in a normally on state, supplying power to the heater. At this time, the heater works normally. When the water level sensor 7 detects that the water level does not meet the heating requirement, it outputs a larger level. At this time, the Schmidt comparator 53 electrically connected to it outputs a high level. The output high level enables the photoelectric thyristor 54 to work, and the relay 55 disconnects the power supply, so that the heater no longer works, further playing an overheating protection role, and avoiding the life of the electric heater from being shortened.

[0044] like Figure 6-8As shown, a lower fixed round block 12 is installed below the flame-retardant junction box 1, and the center of the lower part of the lower fixed round block 12 is fixedly connected to the fixed bracket 4, and two connecting members 8 are movably installed below the lower fixed round block 12, and a uniform member 9 is installed below the connecting member 8. The uniform member 9 rotates and rotates below the lower fixed round block 12 through the connecting member 8. A connecting ring groove 121 is opened on the side of the lower fixed round block 12, and the ends of the two connecting members 8 are movably installed inside the connecting ring groove 121, and the two connecting members 8 are slidably installed inside the connecting ring groove 121.

[0045] The connecting member 8 includes a movable joint 81 and an electric drive column 82 . A motor is installed inside the electric drive column 82 . The motor is connected to the uniform member 9 via a motor shaft. The electric drive column 82 is rotationally connected to the movable joint 81 .

[0046] Specifically, the uniform component 9 is defined as a stirring structure. The upper end of the uniform component 9 is connected to the electric drive column 82, and is driven by the motor inside the electric drive column 82, so that the uniform component 9 rotates to stir the heated liquid and assist the electric heater in heating, so that the electric heater can achieve a more uniform heating effect. In addition, the connecting component 8 can slide inside the connecting ring groove 121, and the uniform component 9 can rotate inside the liquid through the movable joint 81. Therefore, the position of the uniform component 9 inside the liquid that needs to be heated can be adjusted to stir and assist in heating various positions inside the liquid.

[0047] like Figure 8 As shown, the uniform component 9 includes a rotating column 91 connected to the motor shaft of the electric drive column 82 , and a plurality of fixing rings 93 are fixedly installed on the outer side of the rotating column 91 , and a plurality of stirring blades 92 are installed on the outer sides of the plurality of fixing rings 93 .

[0048] Specifically, a plurality of fixed rings 93 are fixedly installed on the outer side of the rotating column 91, and a plurality of stirring blades 92 are installed on the outer side of each fixed ring 93. The plurality of stirring blades 92 are all inclined. When the rotating column 91, the fixed ring 93 and the plurality of stirring blades 92 rotate, they will stir the liquid to be heated, and the liquid in the stirring state can be evenly heated by the electric heater.

[0049] Embodiment 2

[0050] like Figure 9-12As shown, compared with Example 1, another embodiment of the present invention is: a plurality of sliding grooves 931 are opened inside the fixed ring 93, and arc-shaped pieces 932 are slidably installed inside the plurality of sliding grooves 931, the interior of the rotating column 91 is hollow, the sliding grooves 931 are connected with the hollow position inside the rotating column 91, the arc-shaped piece 932 is located between the corresponding two stirring blades 92, edge matching grooves 921 are opened inside the two sides of the stirring blades 92, the edge matching grooves 921 are connected with the sliding grooves 931, and a plurality of connecting springs 933 are installed on the outer side of the arc-shaped piece 932, and one end of the plurality of connecting springs 933 is connected to the inner wall of the corresponding edge matching groove 921.

[0051] A fixed telescopic motor 913 is fixedly installed at the top of the hollow interior of the rotating column 91, a telescopic column 914 is installed below the fixed telescopic motor 913, a lifting column 911 is fixedly installed below the telescopic column 914, the lifting column 911 is slidably arranged inside the rotating column 91, and a plurality of spheres 912 are fixedly installed on the outside of the lifting column 911.

[0052] Specifically, when there are some viscous polymers inside the corrosive liquid to be heated, these polymers will float in the liquid to be heated in the form of lumps or other shapes. When heating such liquids, the inside of the polymers is not easily heated, and traditional heaters do not have the function of breaking up these polymers. In the present invention, when it is necessary to heat such liquids, the two uniform components 9 are placed in a rolling state under the adjustment of the connecting component 8. At this time, the two uniform components 9 rotate in the same direction. At the same time, through the electrical drive of the fixed telescopic motor 913, the telescopic column 914 extends to drive the ball 912 to descend, that is, at this time, the ball 912 will contact the inner sides of the multiple corresponding arc pieces 932, and then squeeze the multiple arc pieces 932 out of the fixed ring 93, and the arc pieces 932 move inside the sliding groove 931 and the corresponding edge matching groove 921 until they move. When the uniform component 9 moves to the limit position, the multiple connecting springs 933 are compressed, and after the arc-shaped piece 932 slides, it will fill the interval between two adjacent stirring blades 92, so that the uniform component 9 will not generate greater resistance when rotating, that is, the rotation of the uniform component 9 can be faster at this time, and the rotation speed of the uniform component 9 is increased, so that the rotating multiple stirring blades 92 and the arc-shaped piece 932 have a cutting effect, which cuts the polymer inside the liquid and plays a role in breaking it up. When the two uniform components 9 are in a roller state, the fixing ring 93 provided on one uniform component 9 is between the two fixing rings 93 provided on the other uniform component 9. When the two uniform components 9 rotate in the same direction, the polymer inside the liquid will be brought between the two uniform components 9 and broken up, and the vertical distance between the fixing ring 93 and the stirring blade 92 provided on the same uniform component 9 can be shortened to achieve a better cutting effect.

[0053] Working principle: After placing the heating component 6 into the corrosive liquid, the wire connector inside the UL flame retardant corrugated hose 3 is connected to the external power supply. The UL flame retardant corrugated hose 3 is a flexible tube with flame retardant properties. It is used to protect cables or pipes and prevent physical damage. It also helps to dissipate heat and compensate for thermal expansion. The UL flame retardant corrugated hose 3 is set to protect the wires and cables connected to the external power supply. The waterproof connector 11 is used to ensure that the cable or pipe connection of the electric heater is waterproof, prevent moisture from entering the electric heater or its electrical system, and avoid short circuit or corrosion. The flame retardant junction box 1 is mainly used to protect the electrical connection part of the electric heater, prevent electrical fires, and ensure the safety of the electrical system. The heating component is powered by an external power supply. 6 performs heating work to heat the corrosive liquid. The temperature protection component 5 will detect the temperature of the heating component 6 to perform overheating protection, and the circuit board overheating protection component 2 will monitor the temperature of the internal wires and cables to perform overheating protection. A three-hole ceramic column 613 is fixedly installed inside the stainless steel hollow tube 611. The existence of the three-hole ceramic column 613 can improve the structural stability and heat conduction efficiency of the heating component 6. The three-hole ceramic column 613 serves as a supporting structure to enhance the mechanical strength of the heating component 6 and prevent the heating component 6 from being deformed after long-term use. The high thermal resistance and good thermal conductivity of the three-hole ceramic column 613 help to evenly distribute heat and improve heating efficiency. The three-hole ceramic column 613 can also serve as an insulator. Ensure electrical isolation between the heating component 6 and the PTFE material hose covering the outside to increase safety in use. When there are some viscous polymers inside the corrosive liquid to be heated, these polymers will float in the liquid to be heated in the form of lumps or other shapes. When heating such liquids, the inside of the polymers is not easily heated, and traditional heaters do not have the function of breaking up these polymers. In the present invention, when it is necessary to heat such liquids, the two uniform components 9 are placed in a rolling state under the adjustment of the connecting component 8. At this time, the two uniform components 9 rotate in the same direction. At the same time, through the electrical drive of the fixed telescopic motor 913, the telescopic column 914 extends to drive the sphere 912 to descend. At this time, the sphere 912 will contact the inner sides of the corresponding arc pieces 932, and then squeeze the arc pieces 932 into the fixed ring 93, and the arc pieces 932 move inside the sliding groove 931 and the corresponding edge matching groove 921 until they move to the limit position. At this time, the multiple connecting springs 933 are compressed. After the arc piece 932 slides, it will fill the interval between two adjacent stirring blades 92, so that the uniform component 9 will not generate greater resistance when rotating. That is, the rotation of the uniform component 9 can be faster at this time, and the rotation speed of the uniform component 9 is increased, so that the rotating multiple stirring blades 92 and the arc piece 932 have a cutting effect, which cuts the polymer inside the liquid and plays a role in breaking it up. When the two uniform components 9 are in a roller state,The fixing ring 93 provided on one uniform component 9 is located between the two fixing rings 93 provided on another uniform component 9. When the two uniform components 9 rotate in the same direction, the polymer inside the liquid will be brought between the two uniform components 9 and broken up. The vertical distance between the fixing ring 93 and the stirring blades 92 provided on the same uniform component 9 can be shortened to achieve a better cutting effect.
