Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic heating equipment, in particular to an environmentally friendly electromagnetic thermal oil heating energy-saving device. Background Art

[0002] Electromagnetic heating is a new, safe, efficient, and energy-saving technology. It heats up faster than traditional electric heating and offers high temperature control accuracy. With a thermal efficiency exceeding 98%, it saves over 20% of electricity compared to electric tubular heating under the same conditions, and cuts preheating time in half.

[0003] However, during the circulation of the heat transfer oil in the oil pipeline heating tube, the heat transfer oil is in direct contact with the heating tube wall, so the temperature of the heat transfer oil on the outside is higher, while the temperature of the heat transfer oil in the center is lower because it cannot directly contact the heating tube wall. Carbon deposits are easily formed on the tube wall, which is difficult to clean and affects the normal operation of the equipment.

[0004] In the prior art, in order to prevent the heat transfer oil from forming carbon deposits on the pipe wall, a simple stirring paddle is usually added to the pipe to disturb the flow and thus avoid temperature differences. For example, the Chinese patent electromagnetic heating heat transfer oil furnace with application number 201710985684.9 discloses an electromagnetic heating heat transfer oil furnace, comprising: a circulating hot oil pump; a heating pipe, which is connected to the oil outlet of the circulating hot oil pump through an oil outlet pipe, the heating pipe consisting of an outer pipe and an inner pipe, the outer pipe is sleeved on the outer wall of the inner pipe, the cross-sectional profile of the outer wall of the outer pipe is a plum blossom shape with alternating convex and concave, the inner wall of the inner pipe is provided with three spiral ridges, and the inner pipe is also provided with a plurality of stirring paddles coaxial with the inner pipe, and the plurality of stirring paddles are evenly spaced in the inner pipe. The invention relates to a heat dissipation device, wherein the heat dissipation device is arranged around the heat-using equipment, and the heat dissipation device is connected to the heating device through an oil inlet pipe; an oil-gas separator is connected to the heat dissipation device through a first oil return pipe; an expansion tank is arranged above the oil-gas separator, and the expansion tank is connected to the oil-gas separator through the oil supply pipe. When the above patent is used to avoid the problem of carbon deposits, it only adds a plurality of stirring blades in the oil guide pipe to stir the heat transfer oil so as to change the flow rate of the heat transfer oil and optimize the temperature difference. However, it accelerates the flow efficiency of the heat transfer oil, resulting in a shorter circulation time of the heat transfer oil per unit volume in the oil guide pipe, and then a shorter heat transfer time, so that the heating is not sufficient, and it is impossible to deal with the carbon deposits that have appeared on the pipe wall. Summary of the Invention

[0005] In view of the above problems, the present invention proposes an environmentally friendly electromagnetic thermal oil heating energy-saving device to solve the technical problem of carbon deposition on the pipe wall mentioned in the above background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] Furthermore, a plurality of rotatable rollers are arranged circumferentially between the first trough body and the second trough body, and a limit retainer is arranged circumferentially between the plurality of rollers.

[0011] Furthermore, at least two pulleys are circumferentially arranged on the outer wall of the cylinder body, and the cylinder bodies arranged parallel to each other are connected by a synchronous belt transmission sleeved inside the pulleys of the two cylinder bodies. Another pulley of one of the cylinder bodies is also sleeved with a transmission belt connected to the driving shaft end of the driving motor.

[0012] Furthermore, the heating tube is continuously bent in an S shape, and the multiple heating sections on the heating tube are all heating tube sections parallel to the axis of the heat-conducting tube, and the heating wires on the outer sides of the heating sections are electromagnetic heating wires.

However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Example 1:

[0029] Combine Figure 1-3The environmentally friendly electromagnetic thermal oil heating and energy-saving device of the present invention mainly comprises a support frame 1, a heat-conducting tube 2, a heating tube 3, a stirring device, a synchronous transmission mechanism, a flow guide structure and an oil inlet mechanism. Its core function is to use electromagnetic heating technology to improve the heating efficiency of the heat-conducting oil and realize efficient heat transfer and energy saving through structural optimization. The present invention is specifically an environmentally friendly electromagnetic thermal oil heating and energy-saving device, comprising a support frame 1, and a plurality of heat-conducting tubes 2 that are parallel to each other and arranged in a rectangular array in the support frame 1. Every two heat-conducting tubes 2 arranged in parallel up and down form a group. The rectangular array arrangement can better enable the upper and lower groups of heat-conducting tubes 2 to work synchronously, making the connection more convenient and the equipment more regular. The heat-conducting tube 2 is wrapped with end heads 201 fixed at both ends and a tube body 202 rotatably embedded between the two end heads 201. The front and rear ends of the support frame 1 are both provided with fixing rings 101. The front and rear end ends 201 of the heat-conducting tube 2 are respectively fixed and relatively arranged in the fixing ring 101 of the support frame 1. The middle part of the support frame 1 also has The transmission ring 102 has 6 sets of nylon transmission wheels 103 installed at the bottom of the transmission ring 102 through bearings. The transmission wheels 103 are evenly distributed around the circumference. The middle of the barrel 202 of the heat-conducting tube 2 is embedded in the transmission ring 102, which supports and limits its radial displacement during rotation. The transmission wheel 103 provides a rotation support structure for the barrel 202, further reducing the rotational friction of the barrel 202. At the same time, the fixed ring 101 provides axial positioning for the entire heat-conducting tube 2, so that the end 202 can be rotated in the process of use. 01 remains completely fixed to provide more stable support for the rotatable barrel 202. The end head 201 is open at one end, and the open ends of the front and rear ends of the end head 201 are arranged opposite to each other. A first groove body 203 is formed on the inner wall of the end head 201. A second groove body 204 is formed on the outer wall of the front and rear ends of the barrel 202. The front and rear ends of the barrel 202 are sealed and embedded in the openings of the two end heads 201, and the second groove body 204 is arranged corresponding to the first groove body 203. The two groove bodies are aligned to form a mounting cavity for the roller 601. A plurality of rotatable rollers 601 are installed in the cavity. A limit retainer 6 is arranged circumferentially between the plurality of rollers 601. The rollers 601 are fixed at intervals by the retainer 6. The rollers 601 are used to reduce the friction between the barrel 202 and the end head 201. The retainer 6 prevents the rollers 601 from deflecting, thereby realizing the free rotation of the barrel 202 relative to the end head 201.

[0030] As a technical solution of this embodiment, further, at least two heating tubes 3 are set in each of the heat-conducting tubes 2. The heating tubes 3 are continuously bent and arranged between the end heads 201 at both ends. The heating tubes 3 are continuously arranged in an S-shaped structure, thereby extending the flow path of the heat-conducting oil, increasing the heating path and improving the heat exchange law of the heat-conducting oil. Heat can be transferred to the entire heating area more evenly, reducing local temperature differences and improving heating uniformity. The heating tube 3 has multiple heating sections 301 with heating wires 4 wound around the outside. The multiple heating sections 301 on the heating tube 3 are all heating tube 3 sections parallel to the axis of the heat-conducting tube 2. The heating wire 4 outside the heating section 301 is an electromagnetic heating wire 4. The winding density of the heating wire 4 is 10 turns / cm, and it directly acts on the metal tube wall of the heating section 301 on the heating tube 3 to achieve efficient electromagnetic induction heating effect.

[0031] As a technical solution of this embodiment, further, combined with Figure 5, each heating section 301 is equipped with a stirring device, one end of the stirring device extends to the outside of the heating section 301 and a driven gear 501 is provided on the extended end, and a transmission gear ring 207 meshing with the driven gear 501 is provided on a section of the inner wall of the cylinder body 202 corresponding to the position of the driven gear 501. The cylinder body 202 drives the transmission gear ring 207 to rotate during the rotation, thereby causing the driven gear 501 meshing with the gear to rotate, so that the stirring device starts working, the stirring device includes a rotatable main shaft 5 mounted on the central axis of the heating section 301 cavity of the heating tube 3, the front and rear ends of the main shaft 5 are extended to the outer end of the heating tube 3, and the main shaft 5 is provided with auger blades 502. The auger structure blades can push the heat transfer oil to flow during the rotation, and in the rotation process, the heat transfer oil is completely mixed and the flow law of the oil is changed, so that the oil on the outside and inside is mixed or the position is changed, thereby improving its heating efficiency, ensuring the consistency of the internal and external temperatures, and And promoting the flow of oil can also prevent the oil from staying on the pipe wall for too long, and the local temperature rise leading to carbonization reaction. Increasing its flow rate and mixing the oil inside and outside can effectively reduce carbon deposition, and ensure the temperature of the oil is consistent, accelerating the overall heating efficiency of the oil. At the same time, when the heating tube 3 is stopped, the auger fan blades 502 continue to rotate to promote the flow of the heat transfer oil and accelerate the cooling of the oil. Compared with the natural cooling of the oil when it is left standing, it is more efficient and reduces the carbonization risk of the standing hot oil. In order to prevent danger, a scraper 503 is also fixed on the main shaft 5 and is placed on the outside of the auger blade 502. The outer end face of the scraper 503 is attached to the inner wall of the heating section 301 cavity. The scraper 503 rotates along with the rotation of the auger blade 502. The outer end face of the scraper 503 can continuously scrape and clean the inner wall of the heating section 301 cavity of the heating tube 3, preventing the high-temperature heat transfer oil from adhering to the inner wall of the tube body for a long time and scraping and cleaning the locally formed carbon deposits, avoiding the vicious cycle of rapid formation and thickening of carbon deposits.

[0032] As a technical solution of this embodiment, further, combined with Figure 6 At least two pulleys 205 are arranged around the outer wall of the cylinder body 202. The cylinder bodies 202 arranged parallel to each other are connected by a synchronous belt 802 sleeved inside the pulleys 205 of the two cylinder bodies 202. The other pulley 205 of one of the cylinder bodies 202 is also sleeved with a transmission belt 801 connected to the driving shaft end of the driving motor 8. When the equipment is running, the driving motor 8 drives one of the heat-conducting tubes 2 in each group of heat-conducting tubes 2 to rotate. Then, the heat-conducting tube 2 is connected to the other heat-conducting tube 2 in the same group through the synchronous belt 802. Under the rotation action of the heat-conducting tube 2, the other heat-conducting tube 2 rotates synchronously with it, achieving a synchronization effect, saving the investment of driving equipment resources, and also achieving the same working efficiency of each group of heat-conducting tubes 2. Figure 1-2The heating tubes 3 in the upper and lower parallel heat-conducting cylinders 2 are connected in parallel through an oil pipe 7. The heating tubes 3 in the same group are connected through one oil pipe 7 so that the heat-conducting oil can be forced to circulate between multiple heating tubes 3, transferring heat to multiple groups of heat-conducting cylinders 2, improving the use efficiency of the heat-conducting oil and forming a circulating oil circuit. The other end of the oil pipe 7 is connected to an oil inlet mechanism, which includes a circulating oil pump 701 and a filter 702 arranged on the oil pipe 7. One end port of the oil pipe 7 is set as an oil return port 703 The oil inlet mechanism is the basic installation equipment of the electromagnetic heating device, which is an existing technology. The main function of the oil inlet mechanism is to provide the input and output of the heat transfer oil for the device, and then filter the impurities of the heat transfer oil that will enter the oil pipe 7 through the filter 702. The filter 702 is a three-way Y-type filter valve. Because it is an existing technology and is not a necessary technical feature in this solution, it will not be described in detail here. The circulating oil pump 701 is a device that accelerates the heat transfer oil into the heating tube 3. This device is also an existing technology and will not be described in detail.

[0033] As a technical solution of this embodiment, further, combined with Figure 6 The heat-conducting tube 2 body 202 is an electromagnetic heat-conducting tube 2 body, and a shielding layer for electromagnetic shielding is attached to the inner wall of the tube body 202. The inner wall of the tube body 202 also has a guide fan blade 206. The heat-conducting tube 2 rotates between the two end heads 201 under the drive of the drive motor 8. A transmission gear ring 207 is provided on the inner wall of the heat-conducting tube 2 corresponding to the position of the driven gear 501. The rotation of the heat-conducting tube 2 can simultaneously drive the driven gear 501 to rotate, so that the stirring device works synchronously, and the electromagnetic shielding layer in the rotating state can effectively change the incident angle and reflection path of the electromagnetic wave, thereby enhancing the electromagnetic shielding effect. The reflection and absorption effect of the waves further improves the shielding effectiveness, especially for high-frequency electromagnetic waves, the shielding effect is more significant. At the same time, the guide fan blades 206 rotate synchronously with the rotation of the heat-conducting tube 2. The guide fan blades 206 can disturb the heat dissipated by the heat-conducting oil in the heat-conducting tube 2 so that it fills the entire heat-conducting tube 2 instead of local heat accumulation, thereby quickly improving the heating efficiency in the barrel. During the heating process, the rotation speed of the heat-conducting tube 2 is slow, and only the heat is diffused and guided. After heating is completed, the heating wire 4 is turned off, and the rotation speed of the heat-conducting tube 2 is increased, so that the guide fan blades 206 rotate quickly to generate wind force, thereby quickly cooling the heating tube 3.

[0034] Example 2:

[0035] Combine Figure 1-6The device specifically includes the following main structures: a support frame 1 for carrying two groups of heat-conducting tubes to ensure structural stability; a heat-conducting tube 2 assembly including an end 201 and a tube body 202; the tube body 202 can be rotatably arranged between the two end heads 201 to provide movement for the conduction of heat in the barrel and the heat dissipation after heating; a heating tube 3 assembly including a heating wire 4 and an S-shaped heating tube 3 to extend the heating path and improve heating efficiency; a stirring device; an auger fan blade 502 combined with a scraper 503 to prevent oil coking and improve heat transfer efficiency; an oil circuit system: a circulating oil pump 701, a filter 702 and 7 oil pipelines to complete oil circulation and purification.

[0036] After ensuring that the entire equipment is in normal working order, start the drive motor 8, and the driving electrical appliance drives the heat-conducting tube 2 body 202 to rotate between the two end heads 201 through the transmission belt 801. One rotating heat-conducting tube 2 body 202 drives the other heat-conducting tube 2 in the same group to rotate through the synchronous belt 802, so that the heat-conducting tubes 2 in the same group work synchronously and achieve consistent working efficiency, ensuring the temperature of the circulating heat-conducting oil is stable. When the tube body 202 rotates, the transmission gear ring 207 on the inner wall of the tube body 202 drives the driven gear 501 to rotate, and the oil passes through the oil pipe 7 filter 702 and the circulating oil. After circulating and purifying, the oil pump 701 enters the heating tube 3. When the driven gear 501 rotates, the auger blades 502 rotate, pushing the oil and mixing it. This ensures heat consistency and prevents carbon deposits on the tube walls caused by high temperatures. The heating wire 4 continuously heats the heating tube 3, and the rotating barrel 202 promotes and diffuses the heat emitted by the oil, ensuring a constant temperature within the barrel. The oil circulates continuously within the heating tube 3, over and over again, achieving continuous heat transfer. Through multiple sets of rotating heat transfer cylinders 2, a built-in stirring system, and a parallel oil circuit design, the thermal oil is quickly and evenly heated. This system is suitable for constant temperature heating needs in industries such as chemical, textile, and food processing, offering energy-saving and environmental protection, high thermal efficiency, and easy maintenance.
