[0032] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0033] 1. A three-dimensional two-way circulation heat storage mechanism is provided. Through the mutual cooperation between the components inside the three-dimensional two-way circulation heat storage mechanism, the heat circulation process during the use of the heating furnace is optimized. Through the transfer flow of the heat-conducting medium inside the heat-conducting side box, the front-end liquid storage tank, the diversion square box and the heat storage flat box, the heat inside the heating furnace body is actively and quickly transferred. In the process of discharging the heated materials, the inside of the heating furnace body is quickly cooled down by transferring the high-temperature heat-conducting molten salt inside the heat-conducting side box to the front-end liquid storage tank. When a new batch of materials is transported to the inside of the heating furnace body and needs to be preheated, the high-temperature heat-conducting molten salt inside the front-end liquid storage tank is quickly transferred to the heat-conducting side box, and the heat of the high-temperature heat-conducting molten salt is used to quickly preheat the inside of the heating furnace body, which effectively improves the preheating efficiency of the heating furnace. Through the reciprocating transfer of the high-temperature heat-conducting molten salt, the residual heat in the previous batch of heating process is stored in a targeted manner and used for the preheating process of the next batch of materials, which effectively improves the heat utilization rate of the heating furnace and reduces the use cost of the heating furnace.

[0034] At the same time, the transfer of low-temperature heat transfer oil between the diversion square box and the heat storage flat box is used to transform the shape and position of the telescopic liquid guide sliding box and the sealing top block, so that after the heating furnace door is opened, the exhaust top pipe can also connect the heating furnace body with the external space, and then the exhaust fan drives the hot air flow inside the heating furnace body to flow continuously along the air guide hole plate and the outer side of the telescopic liquid guide sliding box, and then the heat transfer oil inside the telescopic liquid guide sliding box absorbs and stores the residual heat in the hot air flow, so as to prevent the heat inside the heating furnace body from being directly discharged and wasted, and to insulate the upper space of the inner wall of the heating furnace body when the heating furnace door is opened. At the same time, due to the continuous suction of the exhaust fan, a negative pressure is generated inside the heating furnace body, so that the air flow at the heating furnace body will continue to enter the heating furnace body, so as to reduce the range of heat inside the heating furnace body to diffuse outward through the furnace mouth when the heating furnace body is opened, thereby reducing the temperature at the furnace mouth of the heating furnace body, improving the working environment during the loading and unloading process of the heating furnace, and storing the heat that should be lost inside the heating furnace body through the heat storage flat box and the telescopic liquid guide sliding box, further improving the thermal energy utilization rate during the use of the heating furnace;

[0035] In addition, through the reciprocating transfer of the transmission heat transfer oil inside the lower cavity of the front-end liquid storage tank and the diversion square box, the liquid level of the high-temperature heat transfer molten salt inside the heat transfer side box and the low-temperature heat transfer oil inside the heat storage flat box are quickly controlled to ensure that the high-temperature heat transfer molten salt inside the heat transfer side box is discharged while the inside of the heat storage flat box is filled with liquid, making the waste heat storage process and the waste heat recovery process of the heating furnace smoother. At the same time, in the process of driving the diversion slide plate and the central diversion plate to rise and fall by the transmission heat transfer oil, the transmission heat transfer oil can also exchange heat with the high-temperature heat transfer molten salt and the low-temperature heat transfer oil in real time, and then absorb and store the heat dissipated by the high-temperature heat transfer molten salt and the low-temperature heat transfer oil through the transmission heat transfer oil to maintain the temperature of the lower cavity of the installation frame, thereby extending the insulation time of the high-temperature heat transfer molten salt inside the front-end liquid storage tank and improving the heat transfer process during the use of the heating furnace.

[0036] 2. An internal deflection coating cleaning mechanism is provided. Through the mutual cooperation between the components inside the internal deflection coating cleaning mechanism, the heat preservation and cleaning process of the heating furnace body during use is optimized. After the heated materials inside the heating furnace body are completely discharged, the heating furnace body needs to be temporarily insulated. The swinging protective plate can be quickly changed to a vertical state through the action of the driving motor and gravity, and then the furnace mouth of the heating furnace body is shielded by the swinging protective plate, so as to reduce the heat dissipation rate of the furnace mouth of the heating furnace by reducing the heat dissipation channel, and the front cleaning scraper, the cleaning swing frame and the rear cleaning scraper are driven to clean the inner wall of the heating furnace body during the swinging of the swinging protective plate, so as to realize the rapid cleaning of the inner wall of the heating furnace body and optimize the use process of the heating furnace body;

[0037] At the same time, when the inner wall of the heating furnace body needs to be cleaned after use, the cleaning fan can also be used in conjunction with the air guide angle box and the blowing transverse groove to blow and clean the inner wall of the heating furnace body, thereby effectively improving the cleaning effect inside the heating furnace body. The swinging structure design of the cleaning swing frame and the elastic bendable structure design of the elastic limit plate allow the cleaning swing frame to have a larger range of movement during the swinging process, ensuring the normal sealing process of the swinging protective plate and the cleaning process of the scraper after cleaning. At the same time, the auxiliary traction of the cleaning swing frame by the traction rope and the counterweight slider ensures that the cleaning swing frame can remain flush during idleness.

[0038] To summarize, through the mutual cooperation between the components inside the three-dimensional two-way circulation heat storage mechanism and the internal deflection coating cleaning mechanism, the heat inside the heating furnace is transferred and transported by utilizing the heat-conducting medium connecting the internal components of the heating furnace and the flow of external airflow. When the heating furnace is turned on, the heat is transferred to the bottom of the mounting frame through the flow of high-temperature heat-conducting molten salt inside the heat-conducting side box and the front-end liquid storage tank. During the preheating stage of the heating furnace, the interior of the heating furnace body can be quickly preheated by the reflux of high-temperature heat-conducting molten salt inside the heat-conducting side box, thereby effectively improving the heating efficiency and heat utilization rate of the heating furnace. The exhaust fan and the cleaning fan can actively drive the airflow inside and outside the heating furnace body to flow in a directional manner, so as to fully recover and store the waste heat inside the heating furnace body, and realize rapid blowing and cleaning of the interior of the heating furnace, thereby further optimizing the use process of the heating furnace.

An auxiliary pump 520 is fixedly connected to the end of the rising conduit 519 corresponding to the top position of the mounting base 1. The auxiliary pump 520 is powered by an external power supply. A transport outer tube 521 is fixedly connected to the middle of the top of the auxiliary pump 520. The ends of the transport outer tube 521 are fixedly connected to the connection top boxes 522 corresponding to the four corners of the top of the heating furnace body 3.

[0066] The bottom surfaces of the four connecting top boxes 522 are commonly fixedly connected with a heat storage flat box 523, a telescopic liquid guiding slide box 524 is slidably installed on the inner bottom of the heat storage flat box 523, a reset spring 525 is evenly and evenly fixedly connected to the bottom of the groove of the telescopic liquid guiding slide box 524 along the circumferential direction, and a sealing top block 526 is fixedly connected to the middle of the top surface of the telescopic liquid guiding slide box 524. A long groove is opened at the bottom of the heat storage flat box 523 corresponding to the bottom position of the telescopic liquid guiding slide box 524, and a circular groove is opened at the middle of the top surface of the heat storage flat box 523 corresponding to the outer position of the sealing top block 526. The telescopic liquid guiding slide box 524 and the sealing top block 526 are tightly slidably fitted with the outer wall of the heat storage flat box 523;

[0067] An exhaust top pipe 527 is fixedly connected to the top position of the sealing top block 526 corresponding to the top of the heating furnace main body 3, and an exhaust fan 528 is embedded in the middle of the inner side of the exhaust top pipe 527. The exhaust fan 528 is powered by an external power supply. A protective top net 529 is embedded in the middle of the top of the exhaust top pipe 527. An air guide hole plate 530 is fixedly connected to the bottom position of the heat storage flat box 523 corresponding to the inner top of the heating furnace main body 3. The positions of the sealing top block 526 and the exhaust top pipe 527 correspond to each other, and the outer side of the sealing top block 526 can be tightly slidably fitted with the inner wall of the exhaust top pipe 527. An air guide hole is opened through the middle of the bottom surface of the air guide hole plate 530. Through the mutual cooperation between the internal components of the three-dimensional two-way circulation heat storage mechanism 5, the heat circulation process during the use of the heating furnace is optimized. The transfer flow of the heat-conducting medium inside the flat box 523 actively and quickly transfers the heat inside the heating furnace body 3. In the process of discharging the heated materials, the inside of the heating furnace body 3 is quickly cooled down by transferring the high-temperature heat-conducting molten salt inside the heat-conducting side box 502 to the front end liquid storage tank 507. When a new batch of materials is transported to the heating furnace body 3 and needs to be preheated, the high-temperature heat-conducting molten salt inside the front end liquid storage tank 507 is quickly transferred to the heat-conducting side box 502, and the heat of the high-temperature heat-conducting molten salt is used to quickly preheat the inside of the heating furnace body 3, which effectively improves the preheating efficiency of the heating furnace. Through the reciprocating transfer of the high-temperature heat-conducting molten salt, the residual heat from the previous batch of heating process is stored in a targeted manner and used for the preheating process of the next batch of materials, which effectively improves the heat utilization rate of the heating furnace and reduces the use cost of the heating furnace.

[0068] At the same time, by utilizing the transfer of low-temperature heat transfer oil between the diversion square box 516 and the heat storage flat box 523, the shape and position of the telescopic liquid guide slide box 524 and the sealing top block 526 are transformed, so that after the heating furnace door 4 is opened, the exhaust top pipe 527 can also connect the heating furnace body 3 with the external space, and then the exhaust fan 528 drives the hot air flow inside the heating furnace body 3 to flow continuously along the air guide hole plate 530 and the outer side of the telescopic liquid guide slide box 524, and then the residual heat in the hot air flow is absorbed and stored by the heat transfer oil inside the telescopic liquid guide slide box 524, so as to prevent the heat inside the heating furnace body 3 from being directly discharged and wasted, and When the heating furnace door 4 is opened, the upper space of the inner wall of the heating furnace body 3 is insulated. At the same time, due to the continuous suction of the exhaust fan 528, negative pressure is generated inside the heating furnace body 3, so that the airflow at the heating furnace body 3 will continue to enter the heating furnace body 3, so as to reduce the range of heat inside the heating furnace body 3 to diffuse outward through the furnace mouth when the heating furnace body 3 is opened, thereby reducing the temperature at the furnace mouth of the heating furnace body 3, improving the working environment during the loading and unloading of the heating furnace, and storing the heat that should be lost inside the heating furnace body 3 through the heat storage flat box 523 and the telescopic liquid guide sliding box 524, further improving the thermal energy utilization rate during the use of the heating furnace;

[0069] And through the reciprocating transfer of the transmission heat transfer oil in the lower cavity of the front end liquid storage tank 507 and the diverter box 516, the liquid level of the high-temperature heat transfer molten salt in the heat transfer side box 502 and the low-temperature heat transfer oil in the heat storage flat box 523 are quickly controlled to ensure that the high-temperature heat transfer molten salt in the heat transfer side box 502 is discharged while the heat storage flat box 523 is filled with liquid, so that the waste heat storage process and waste heat recovery process of the heating furnace are smoother. At the same time, in the process of driving the diverter slide plate 510 and the central diverter plate 517 to rise and fall by the transmission heat transfer oil, the transmission heat transfer oil can also exchange heat with the high-temperature heat transfer molten salt and the low-temperature heat transfer oil in real time, and then the heat dissipated by the high-temperature heat transfer molten salt and the low-temperature heat transfer oil is absorbed and stored by the transmission heat transfer oil to maintain the temperature of the lower cavity of the installation base 1, thereby extending the insulation time of the high-temperature heat transfer molten salt in the front end liquid storage tank 507 and improving the heat transfer process during the use of the heating furnace.

An air guide elbow 619 is fixedly connected to the middle of one end of the cleaning fan 618 corresponding to the internal position of the heating furnace body 3.

The middle edges of both sides of the wind guide angle box 620 are evenly provided with blowing transverse grooves 621 in the vertical direction. The sides of the blowing transverse grooves 621 are kept parallel to the inner wall of the heating furnace body 3. The outer side of the counterweight slider 613 is tightly slidably fitted with the inner wall of the wind guide angle box 620. The mutual cooperation between the internal components of the internal deflection covering cleaning mechanism 6 optimizes the heating process. During the heat preservation and cleaning process of the heating furnace body 3 in use, after the heated materials inside the heating furnace body 3 are completely discharged, the heating furnace body 3 needs to be temporarily insulated. The swinging protection plate 603 can be quickly changed to a vertical state by driving the motor 601 and gravity, and then the furnace mouth of the heating furnace body 3 is shielded by the swinging protection plate 603, so as to reduce the heat dissipation rate of the furnace mouth of the heating furnace by reducing the heat dissipation channel, and the front cleaning scraper 605, the cleaning swing frame 607 and the rear cleaning scraper 608 are driven to clean the inner wall of the heating furnace body 3 during the swinging of the swinging protection plate 603, so as to realize the rapid cleaning of the inner wall of the heating furnace body 3 and optimize the use process of the heating furnace body 3;

[0076] At the same time, when the inner wall of the heating furnace body 3 needs to be cleaned after using the heating furnace, the cleaning fan 618 can also be used to blow and clean the inner wall of the heating furnace body 3 in cooperation with the air guide angle box 620 and the blowing transverse groove 621, thereby effectively improving the cleaning effect inside the heating furnace body 3. The swinging structure design of the cleaning swing frame 607 and the elastic bendable structure design of the elastic limiting plate 611 allow the cleaning swing frame 607 to have a larger range of movement during the swinging process, thereby ensuring the normal sealing process of the swinging protective plate 603 and the cleaning process of the cleaning rear scraper 608. At the same time, the auxiliary traction of the cleaning swing frame 607 by the traction rope 612 and the counterweight slider 613 ensures that the cleaning swing frame 607 can remain flush during the idle process.

[0077] The working principle and use process of the present invention: When using the heating furnace, the present invention needs to first install the heating furnace body 3 on the foundation through the installation base 1, and use the supporting bottom piles 2 to auxiliary support the bottom of the installation base 1. Then, after completing the heating of a batch of materials, when it is necessary to recover the internal heat of the heating furnace body 3, start the transfer pump 514 to transfer the heat transfer oil of the lower layer of the front end liquid storage tank 507 through the transfer bottom barrel 513 into the diversion square box 516 through the transfer horizontal pipe 515, so that the liquid level of the lower layer inside the front end liquid storage tank 507 gradually decreases, and the diversion slide plate 510 and the floating bottom ring 511 decrease together with the heat transfer oil of the lower layer of the front end liquid storage tank 507, and the isolation upper valve 504 is opened synchronously. The high-temperature heat-conducting molten salt in the multiple heat-conducting side boxes 502 flows into the diversion center box 506 through the transfer connecting cross pipe 505, and then the high-temperature heat-conducting molten salt is introduced into the front-end liquid storage tank 507 through the diversion center box 506 for storage and heat preservation, and the heat inside the heating furnace body 3 is quickly taken away during the discharge of the high-temperature heat-conducting molten salt, so as to achieve rapid cooling of the inside of the heating furnace body 3, and at the same time, the outside of the front-end liquid storage tank 507 is insulated and protected by the heat-insulating heating cover 508, and when the temperature inside the front-end liquid storage tank 507 drops, the heat-insulating heating cover 508 is used to auxiliary heat the front-end liquid storage tank 507, so as to keep the internal temperature of the front-end liquid storage tank 507 within a suitable range;

[0078] After the heat transfer oil in the front liquid storage tank 507 enters the lower cavity of the diverter box 516, it will drive the central diverter plate 517 at the bottom of the diverter box 516 to rise, and then in the process of the central diverter plate 517 rising, the low-temperature heat transfer oil in the upper chamber of the diverter box 516 will enter the rising conduit 519, and in the process of the central diverter plate 517 rising, it will be assisted by the balance telescopic spring 518 to ensure that the rising process of the central diverter plate 517 is smoother, and the low-temperature heat transfer oil entering the rising conduit 519 will continue to be transported to the inside of the transfer outer pipe 521 through the auxiliary pump 520, and then introduced into the inside of the connecting top box 522 through the transfer outer pipe 521, and finally introduced into the inside of the heat storage flat box 523 through the connecting top box 522;

[0079] As the amount of low-temperature heat transfer oil in the heat storage flat box 523 increases, its internal hydraulic pressure will continue to increase, thereby enabling the telescopic liquid guide slide box 524 to overcome the pulling force of the return spring 525 and drive the sealing top block 526 to slide downward along the inside of the heat storage flat box 523. When the sealing top block 526 is completely withdrawn from the exhaust top pipe 527, the exhaust fan 528 is started to suck the air flow inside the heating furnace body 3, and under the guidance of the air guide hole plate 530, the hot air flow inside the heating furnace body 3 can rise along the middle hole at the bottom of the air guide hole plate 530, and after the hot air flow rises to the upper space of the air guide hole plate 530, the hot air flow flows from the center to the edge along the bottom of the telescopic liquid guide slide box 524 again, and heats the low-temperature heat transfer oil in the telescopic liquid guide slide box 524 during the flow process, thereby realizing the recovery of residual heat inside the heating furnace body 3, and protecting the top of the exhaust top pipe 527 through the protective top net 529 during the operation of the exhaust fan 528;

[0080] When a new batch of materials to be processed is transported to the interior of the heating furnace body 3 and the heating furnace door 4 is closed, if the interior of the heating furnace needs to be preheated, the auxiliary pump 520 is started in reverse to guide the heat transfer oil in the diversion box 516 back to the interior of the front liquid storage tank 507, and in the process of the liquid level in the lower cavity of the front liquid storage tank 507 continuously rising, the high-temperature heat-conducting molten salt in the upper cavity of the front liquid storage tank 507 is simultaneously driven to flow back to the interior of the heat-conducting side box 502, so as to quickly preheat the interior of the heating furnace body 3 through the high-temperature heat-conducting molten salt in the heat-conducting side box 502;

[0081] When the heating furnace is turned on and needs to be cleaned and insulated, the driving motor 601 is started to drive the driving cross bar 602 to rotate, and then the swing protection plate 603 is driven to rotate synchronously through the rotation of the driving cross bar 602. During the rotation of the swing protection plate 603, the cleaning front scraper 605 installed in the side groove 604 is driven to scrape along the inner wall of the heating furnace body 3 to achieve the cleaning of the inner wall of the heating furnace body 3, and during the swinging of the swing protection plate 603, the elastic limit plate 605 installed in the arc groove 609 is used to scrape the inner wall of the heating furnace body 3. 11 drives the installation beam 610 to move synchronously, and synchronously drives the cleaning swing frame 607 to swing during the movement of the installation beam 610. The swing of the cleaning swing frame 607 drives the cleaning rear scraper 608 to synchronously scrape the inner wall of the heating furnace body 3, further expanding the cleaning range inside the heating furnace body 3. At the same time, during the swinging of the cleaning swing frame 607, the traction rope 612 drives the counterweight slider 613 to slide and rise along the inside of the air guide angle box 620, so as to slide and store energy through the rise of the counterweight slider 613;

[0082] When the cleaning swing frame 607 swings to the lowest end and contacts the inner bottom surface of the heating furnace body 3, as the swing protection plate 603 continues to rotate, the cleaning swing frame 607 will drive the elastic limit plate 611 to bend under the action of the reaction force generated after contacting the heating furnace body 3, and make the cleaning swing frame 607 bend along the end of the installation short plate 606, so that the swing protection plate 603 becomes a vertical state, so as to realize the rapid sealing of the end of the heating furnace body 3 when the heating furnace door 4 is not closed, so as to reduce the heat loss inside the heating furnace body 3 when the heating furnace door 4 is opened;

[0083] When the heating furnace needs dust removal after one use, the cleaning fan 618 is started to suck the airflow at the end of the air guide top cover 614, so that the external air can pass through the protective end net 617 into the air guide top cover 614, and the large particles of impurities in the airflow are filtered and intercepted by the collecting slide box 615 and the filtering vertical net 616, and then the high-speed airflow is introduced into the air guide angle box 620 through the air guide bend 619, and the high-speed airflow is blown toward the inner wall of the heating furnace body 3 through the blowing horizontal slot 621, so as to realize the rapid blowing and cleaning of the inner wall of the heating furnace body 3.

[0084] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
