Description

Technical Field

[0001] This invention relates to the field of asphalt mixture production technology, specifically to an adjustable modular assembly structure and method based on electromagnetic heating. Background Technology

[0002] Fuel energy consumption accounts for approximately 93.3% of the total energy consumption in the asphalt mixture production process, and exhaust emissions also account for over 90%, mainly concentrated in the drying and heating of aggregates and the heat insulation heating of asphalt. The asphalt heating and insulation system uses a thermal oil heater as the heat source. Thermal oil heating utilizes high flash point mineral oil heated to a relatively high temperature as the heat medium, circulating it in conduits and serpentine pipes to heat the asphalt outside the pipes. The advantages of this method are that the thermal oil heater used is compact, easy to use, provides gentle heating, has high thermal efficiency, is easy to automatically control in temperature, and heats the asphalt uniformly and rapidly.

[0003] An electromagnetic heater is a device that converts electrical energy into heat energy using the principle of electromagnetic induction. Compared with traditional heating methods, electromagnetic induction heating is a self-heating phenomenon that does not have a significant impact on the environment. Electromagnetic induction has low heat loss and good energy-saving effect. In the process of electromagnetic induction heating, there is no direct contact between the induction coil and the metal part being heated. The energy is transferred through electromagnetic induction, which reduces a lot of heat loss during the conduction process and improves efficiency by about 85%. The temperature of the metal part rises quickly because the resistance of the metal part is low, so a small electromotive force can generate a strong eddy current, generating more Joule heat and less heat loss, so the metal part heats up very quickly.

[0004] In existing technologies, when heating heat transfer oil, the electromagnetic heating mechanism mainly includes an electromagnetic coil and a metal heating tube. The electromagnetic coil is sleeved on the metal heating tube, and the heat transfer oil is input into the metal heating tube for heating and then output. In order to improve the heating effect of multiple asphalt materials, multiple electromagnetic heating modules need to be assembled together. In order to improve the heating efficiency and heat preservation effect, each electromagnetic heating module is usually installed in a compact manner in the heating box. Therefore, during the heating process, the air circulation between each electromagnetic heating module is poor, which is not conducive to the heat dissipation of the electromagnetic heating module. If this heat is not dissipated in time, it will cause the internal temperature of the equipment to rise. Excessive temperature will accelerate the aging of the internal components of the equipment and shorten the service life of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable modular assembly structure and method based on electromagnetic heating, thereby solving the following technical problems:

[0006] The existing electromagnetic heating modules have poor air circulation, which affects the normal heat dissipation of the equipment.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An adjustable modular assembly structure based on electromagnetic heating includes a heating box, in which at least one row of electromagnetic heating modules is arranged, and each row of electromagnetic heating modules includes several groups of electromagnetic heating modules arranged at equal intervals.

[0009] The heating box is symmetrically provided with a set of main oil pipelines on both sides. The other end of the main oil pipeline is connected to the oil inlet of the serpentine pipe used for heating asphalt material through an oil pump. Each main oil pipeline is provided with a main return oil pipeline at the bottom. The main return oil pipeline is connected to the oil outlet of the serpentine pipe through a circulation pump.

[0010] It also includes an adjustment module, which is used to adjust the spacing between two adjacent sets of electromagnetic heating modules.

[0011] Preferably, each group of electromagnetic heating modules includes an oil inlet pipe and an oil outlet pipe. The oil inlet pipe is connected to the main oil return pipe through a first oil return branch pipe or a second oil return branch pipe, and the oil outlet pipe is connected to the main oil delivery pipe through a first oil delivery branch pipe or a second oil delivery branch pipe.

[0012] Preferably, the first oil supply branch pipe is used to insert and cooperate with the second oil supply branch pipe, and the outer wall of the first oil supply branch pipe is slidably attached to the inner wall of the second oil supply branch pipe;

[0013] The first return oil branch pipe is used to connect with the second oil supply branch pipe, and the outer wall of the first return oil branch pipe slides and fits against the inner wall of the second return oil branch pipe.

[0014] Preferably, for any group of the electromagnetic heating modules, when its oil inlet pipe is connected to the first oil return branch pipe, its oil outlet pipe is connected to the first oil delivery branch pipe.

[0015] When its inlet pipe is connected to the second return oil branch pipe, its outlet pipe is connected to the second delivery oil branch pipe.

[0016] Preferably, for two adjacent sets of electromagnetic heating modules, when the oil inlet pipe of one set of electromagnetic heating modules is connected to the first return oil branch pipe and the oil outlet pipe is connected to the first delivery oil branch pipe, the oil outlet pipe of the other set of electromagnetic heating modules is limited to being connected to the second return oil branch pipe and the oil outlet pipe is connected to the second delivery oil branch pipe.

[0017] The first return oil branch pipe and the second return oil branch pipe are connected by an insertion joint, and the first oil delivery branch pipe and the second oil delivery branch pipe are connected by an insertion joint.

[0018] Preferably, the first return oil branch pipe is also used for insertion and connection with the main oil pipeline, and the outer wall of the first return oil branch pipe slides and fits against the inner wall of the main oil pipeline.

[0019] Preferably, the first oil supply branch pipe is also used to connect with the main return oil pipe, and the outer wall of the first oil supply branch pipe slides against the inner wall of the main return oil pipe.

[0020] Preferably, the adjustment module includes a positioning seat fixedly arranged on the oil outlet pipe, and a guide rod arranged in the heating box. Several sets of guide seats are slidably arranged on the guide rod. An adjustment plate is fixedly arranged at the bottom of each set of guide seats. Two sets of adjustment rods are symmetrically arranged at both ends of the adjustment plate. Each set of adjustment rods is rotatably connected to the adjustment plate through a first hinge seat. The other end of the adjustment rod is rotatably connected to the positioning seat through a second hinge seat.

[0021] The heating box is equipped with a fixed adjusting electric cylinder, and the telescopic end of the adjusting electric cylinder is fixed to the guide rod.

[0022] Preferably, each group of second hinge seats includes support plates symmetrically arranged on the positioning seat, with a pin spirally arranged in the support plate, and a through hole for fitting onto the pin at the end of the adjusting rod away from the first hinge seat.

[0023] An assembly method for an adjustable modular assembly structure based on electromagnetic heating includes the following steps:

[0024] Adjust the electric cylinder to drive the guide rod down until the space between the main oil supply pipe and the main return oil pipe on both sides can accommodate several sets of oil supply branch pipes and return oil branch pipes to be installed;

[0025] Connect the first oil supply branch pipe and the main oil supply pipe, as well as the first oil return branch pipe and the main oil return pipe of the electromagnetic heating modules at both ends, and then connect the positioning seat of the electromagnetic heating modules at both ends to the adjusting rod.

[0026] Place each electromagnetic heating module in the middle position into its corresponding position, and then connect its positioning seat to the adjusting rod respectively;

[0027] The electric cylinder drives the guide rod to rise. During the rise, the guide rod can synchronously drive each electromagnetic heating module to converge in the heating box through the guide seat and the adjusting rod, so that the first oil return branch pipe and the second oil return branch pipe are connected accordingly, and the first oil delivery branch pipe and the second oil delivery branch pipe are connected accordingly, and the assembly is completed.

[0028] The beneficial effects of this invention are:

[0029] (1) After the electromagnetic heating module is installed in the heating box, in the initial state, in order to achieve the effect of rapid heating, the electromagnetic heating modules can be adjusted to move closer together by adjusting the module synchronously, so as to reduce the distance between two adjacent electromagnetic heating modules. On the one hand, the air flow rate of the two adjacent electromagnetic heating modules can be reduced, so that the temperature rises faster. On the other hand, the heat conduction between the two adjacent electromagnetic heating modules can be carried out through thermal radiation, further improving the heating rate, thereby achieving the effect of saving costs and reducing carbon emissions.

[0030] (2) In order to improve the heat dissipation efficiency of the electromagnetic heating module during the heating process of the asphalt material, the present invention adjusts the module to drive each electromagnetic heating module to move away from each other, thereby increasing the air flow rate of the two adjacent electromagnetic heating modules, dissipating heat from the electromagnetic heating module, ensuring the normal operation of each electromagnetic heating module, and improving its service life.

[0031] (3) In this invention, when the adjustment module drives the electromagnetic heating modules on both sides to approach or move away from each other, the electromagnetic heating module can simultaneously drive the first return oil branch pipe to slide in the second return oil branch pipe and the first oil delivery branch pipe to slide in the second oil delivery branch pipe. At the same time, the first return oil branch pipe and the second return oil branch pipe, as well as the first oil delivery branch pipe and the second oil delivery branch pipe, are always in a state of mutual communication, and the heat transfer oil can still flow normally in the pipe body.

[0032] (4) In this invention, when it is necessary to disassemble the electromagnetic heating module, the present invention directly drives two adjacent electromagnetic heating modules to move away from each other and reach a certain distance by adjusting the module, so that the first oil return branch pipe is separated from the second oil return branch pipe and the first oil delivery branch pipe is separated from the second oil delivery branch pipe. Disassembly and assembly are very convenient, and the assembly module has integrity, making relocation and disassembly and replacement more convenient.

[0033] (5) Compared with traditional burner-type heating devices, the modular assembly electromagnetic heating device of the present invention has a higher overall integrity, making it easier to handle and transport, and also easier to disassemble and assemble. Correspondingly, the present invention adopts electromagnetic heating, which can utilize off-peak electricity prices at night to heat asphalt mixtures, resulting in lower electricity costs and effectively reducing production costs.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] Please see Figures 1-2 As shown, the present invention is an adjustable modular assembly structure based on electromagnetic heating, including a heating box 1. The heating box 1 is provided with at least one row of electromagnetic heating modules, and each row of electromagnetic heating modules includes several sets of electromagnetic heating modules 3 arranged at equal intervals. In this embodiment, the heating box 1 is provided with two rows of electromagnetic heating modules, and each row of electromagnetic heating modules includes five sets of electromagnetic heating modules 3. Correspondingly, each row can also be provided with six or eight sets of electromagnetic heating modules 3, which is not limited to meet the actual heating requirements of heat transfer oil.

[0045] In this embodiment, a set of main oil pipes 102 are symmetrically arranged on both sides of the heating box 1. The other end of the main oil pipe 102 is connected to the oil inlet of the serpentine pipe used for heating the asphalt material through an oil pump. Each main oil pipe 102 has a main return oil pipe 103 at its bottom. The main return oil pipe 103 is connected to the oil outlet of the serpentine pipe through a circulation pump. Specifically, in this embodiment, after the heat transfer oil is heated by each set of electromagnetic heating modules 3, the oil pump delivers the heat transfer oil to the serpentine pipe through the main oil pipe 102 to heat the asphalt material. Then, the heat transfer oil in the serpentine pipe is delivered to the electromagnetic heating module 3 again through the main return oil pipe 103 by the circulation pump to achieve the effect of circulating heating.

[0046] It also includes an adjustment module, which is used to adjust the spacing between two adjacent electromagnetic heating modules 3. It can be explained that after the electromagnetic heating modules 3 are installed in the heating chamber 1, in the initial state, in order to achieve rapid heating, this embodiment can use the adjustment module to synchronously adjust each electromagnetic heating module 3 to move closer together, thereby reducing the spacing between two adjacent electromagnetic heating modules 3. On the one hand, this reduces the airflow rate between the two adjacent electromagnetic heating modules 3, making the temperature rise faster; on the other hand, it allows heat conduction between the two adjacent electromagnetic heating modules 3 through thermal radiation, further improving the heating rate. Correspondingly, during the heating process of the asphalt material, in order to improve the heat dissipation efficiency of the electromagnetic heating modules 3, this embodiment uses the adjustment module to drive each electromagnetic heating module 3 further away from each other, thereby increasing the airflow rate between the two adjacent electromagnetic heating modules 3, dissipating heat from the electromagnetic heating modules 3, ensuring the normal operation of each electromagnetic heating module 3, and improving its service life.

[0047] Example 2

[0048] Based on Example 1, please refer to Figure 3 and Figures 5-6 Each electromagnetic heating module 3 includes an oil inlet pipe 403 and an oil outlet pipe 4. The oil inlet pipe 403 is connected to the main return oil pipe 103 through a first return oil branch pipe 404 or a second return oil branch pipe 405. The oil outlet pipe 4 is connected to the main oil delivery pipe 102 through a first delivery oil branch pipe 401 or a second delivery oil branch pipe 402. Specifically, the heat transfer oil heated by the electromagnetic heating module 3 first enters the first delivery oil branch pipe 401 or the second delivery oil branch pipe 402 through the oil outlet pipe 4, and then enters the main oil delivery pipe 102. The heat transfer oil that returns first enters the first return oil branch pipe 404 or the second return oil branch pipe 405 through the main return oil pipe 103, and then enters the oil inlet pipe 403 through the first return oil branch pipe 404 or the second return oil branch pipe 405, so as to be heated again by the electromagnetic heating module 3 in the future.

[0049] As a further embodiment, the first oil supply branch pipe 401 is used to be inserted into and cooperate with the second oil supply branch pipe 402, and the outer wall of the first oil supply branch pipe 401 is slidably attached to the inner wall of the second oil supply branch pipe 402.

[0050] Correspondingly, the first return oil branch pipe 404 is used to connect with the second oil supply branch pipe 402, and the outer wall of the first return oil branch pipe 404 slides against the inner wall of the second return oil branch pipe 405.

[0051] In this embodiment, please refer to Figure 3 and Figures 5-6 For any group of electromagnetic heating modules 3, when its oil inlet pipe 403 is connected to the first return oil branch pipe 404, its oil outlet pipe 4 is connected to the first oil supply branch pipe 401. Correspondingly, when its oil inlet pipe 403 is connected to the second return oil branch pipe 405, its oil outlet pipe 4 is connected to the second oil supply branch pipe 402. It should be noted that in this embodiment, it is necessary to ensure that the inner diameter of the return oil branch pipe connected to each group of electromagnetic heating modules 3 is equal to the inner diameter of the oil supply branch pipe.

[0052] For two adjacent sets of electromagnetic heating modules 3, when the oil inlet pipe 403 of one set of electromagnetic heating modules 3 is connected to the first return oil branch pipe 404 and the oil outlet pipe 4 is connected to the first delivery oil branch pipe 401, the oil outlet pipe 4 of the other set of electromagnetic heating modules 3 is limited to being connected to the second return oil branch pipe 405 and the second delivery oil branch pipe 402. The first return oil branch pipe 404 and the second return oil branch pipe 405 are inserted into each other, and the first delivery oil branch pipe 401 and the second delivery oil branch pipe 402 are inserted into each other. It can be explained that when the adjustment module drives the electromagnetic heating modules 3 on both sides to move closer or further apart, the electromagnetic heating modules 3 can simultaneously drive the first return oil branch pipe 404 to slide in the second return oil branch pipe 405, and the first oil supply branch pipe 401 to slide in the second oil supply branch pipe 402. At the same time, the first return oil branch pipe 404 and the second return oil branch pipe 405, as well as the first oil supply branch pipe 401 and the second oil supply branch pipe 402, are always in a state of mutual communication, and the heat transfer oil can still flow normally in the pipe body.

[0053] It should also be noted that when the electromagnetic heating module 3 needs to be disassembled, in this embodiment, the two adjacent electromagnetic heating modules 3 are directly driven away from each other and a certain distance is reached by adjusting the module, so that the first oil return branch pipe 404 is disengaged from the second oil return branch pipe 405, and the first oil delivery branch pipe 401 is disengaged from the second oil delivery branch pipe 402.

[0054] Furthermore, the first return branch pipe 404 is also used to connect with the main oil pipeline 102, and the outer wall of the first return branch pipe 404 slides against the inner wall of the main oil pipeline 102.

[0055] The first oil supply branch pipe 401 is also used to connect with the main return oil pipe 103, and the outer wall of the first oil supply branch pipe 401 slides against the inner wall of the main return oil pipe 103; wherein, for each electromagnetic heating module, the oil outlet pipe 4 of the electromagnetic heating module 3 at both ends is connected to the first oil supply branch pipe 401, and the oil inlet pipe 403 is connected to the first return oil branch pipe 404; specifically, in this embodiment, when the adjustment module drives each electromagnetic heating module 3 to move, the first oil supply branch pipe 401 of the electromagnetic heating module 3 located at both ends slides on the side of the main oil supply pipe 102, and the first return oil branch pipe 404 slides on the side of the main return oil pipe 103, so as to realize the transportation of heat transfer oil;

[0056] It should be noted that when the adjustment module drives each electromagnetic heating module 3 to move synchronously, the movement distance of the electromagnetic heating modules 3 that are closer to the sides of the heating box 1 is greater than the movement distance of the electromagnetic heating modules 3 that are closer to the inside. Therefore, in this embodiment, the lengths of the first oil supply branch pipe 401 and the first oil return branch pipe 404 of the electromagnetic heating modules 3 at both ends need to be set accordingly to avoid the phenomenon that the first oil supply branch pipe 401 is separated from the main oil supply pipe 102 and the first oil return branch pipe 404 is separated from the main oil return pipe 103 when the electromagnetic heating modules 3 are gathered together.

[0057] Please see Figure 6 Each electromagnetic heating module 3 includes a metal heating tube 303, which is made of carbon steel or 304 stainless steel. An insulating sleeve 302 is fitted around the outside of the metal heating tube 303. The insulating sleeve 302 can be made of ceramic material. An electromagnetic coil 301 is wound around the outside of the insulating sleeve 302. Specifically, in this embodiment, the electromagnetic coil 301 generates an alternating magnetic field to generate eddy currents in the tube wall to heat it up.

[0058] In this embodiment, the oil outlet pipe 4 is connected to one end of the metal heating pipe 303, and the oil inlet pipe 403 is connected to the other end of the metal heating pipe 303. The oil outlet pipe 4 and the oil inlet pipe 403 are fixed to the metal heating pipe 303 by a locking nut, and the two are detachable.

[0059] As a further solution in this embodiment, please refer to Figures 3-4 as well as Figure 6The adjustment module includes a positioning seat 504 fixedly arranged on the oil outlet pipe 4, and a guide rod 5 arranged in the heating box 1. Several sets of guide seats 501 are slidably arranged on the guide rod 5. An adjustment plate 502 is fixedly arranged at the bottom of each set of guide seats 501. Two sets of adjustment rods 503 are symmetrically arranged at both ends of the adjustment plate 502. Each set of adjustment rods 503 is rotatably connected to the adjustment plate 502 through a first hinge seat 506. The other end of the adjustment rod 503 is rotatably connected to the positioning seat 504 through a second hinge seat 505. The connection is as follows: an adjusting electric cylinder 2 is fixedly installed on the heating box 1, and the telescopic end of the adjusting electric cylinder 2 is fixed to the guide rod 5. It can be explained that when adjusting the relative position of each electromagnetic heating module 3, the adjusting electric cylinder 2 is activated to drive the guide rod 5 to rise and fall in the heating box 1. During the rising and falling process, the guide rod 5 can synchronously drive each electromagnetic heating module 3 to converge or diffuse in the heating box 1 through the guide seat 501 and the adjusting rod 503. During this process, the guide seat 501 slides synchronously on the guide rod 5 to adjust the position accordingly.

[0060] For easier disassembly and assembly, please refer to [link / reference]. Figure 4 Each set of second hinge seats 505 includes support plates 507 symmetrically arranged on positioning seats 504. A pin 508 is spirally arranged in the support plate 507. The end of the adjusting rod 503 away from the first hinge seat 506 has a through hole for fitting onto the pin 508. It can be noted that when installing the adjusting rod 503, the through hole of the adjusting rod 503 is first placed between the two sets of support plates 507, and then the pin 508 is spirally fixed through the support plate 507 and the through hole.

[0061] Furthermore, in this embodiment, when installing each electromagnetic heating module 3, the guide rod 5 is first lowered by adjusting the electric cylinder 2 until the space between the main oil supply pipe 102 and the main return oil pipe 103 on both sides can accommodate several sets of oil supply branch pipes and return oil branch pipes to be installed. Then, the first oil supply branch pipe 401 of the electromagnetic heating modules 3 at both ends is inserted and positioned with the main oil supply pipe 102 and the first return oil branch pipe 404 is inserted and positioned with the main return oil pipe 103. Next, the positioning seats 504 of the electromagnetic heating modules 3 at both ends are connected with the adjusting rod 503. Finally, each electromagnetic heating module 3 in the middle position is placed in its corresponding position. Then, the positioning seat 504 is connected to the adjusting rod 503 respectively. Finally, the guide rod 5 is driven to rise by the adjusting electric cylinder 2. During the rising process, the guide rod 5 can synchronously drive each electromagnetic heating module 3 to converge in the heating box 1 through the guide seat 501 and the adjusting rod 503, so that the first oil return branch pipe 404 and the second oil return branch pipe 405 are inserted accordingly, and the first oil supply branch pipe 401 and the second oil supply branch pipe 402 are inserted accordingly, thus realizing the installation of each electromagnetic heating module 3. The disassembly steps are the reverse of the installation steps. The disassembly and assembly of the electromagnetic heating module 3 in this embodiment are very convenient.

[0062] In this embodiment, at least one set of fans 101 are installed on the side wall of the heating box 1 to dissipate heat.

[0063] An assembly method for an adjustable modular assembly structure based on electromagnetic heating includes the following steps:

[0064] S1, please refer to Figures 2-4 Adjust the electric cylinder 2 to drive the guide rod 5 to descend until the space between the main oil supply pipe 102 and the main return oil pipe 103 on both sides can accommodate several sets of oil supply branch pipes and return oil branch pipes to be installed.

[0065] S2. Connect the first oil supply branch pipe 401 of the electromagnetic heating module 3 at both ends to the main oil supply pipe 102 and the first oil return branch pipe 404 to the main oil return pipe 103 for positioning, and then connect the positioning seat 504 of the electromagnetic heating module 3 at both ends to the adjusting rod 503.

[0066] S3. Place each electromagnetic heating module 3 in the middle position into the corresponding position, and then connect its positioning seat 504 to the adjusting rod 503 respectively.

[0067] S4. Adjust the electric cylinder 2 to drive the guide rod 5 to rise. During the rising process, the guide rod 5 can synchronously drive each electromagnetic heating module 3 to converge in the heating box 1 through the guide seat 501 and the adjusting rod 503, so that the first oil return branch pipe 404 and the second oil return branch pipe 405 are connected accordingly, and the first oil delivery branch pipe 401 and the second oil delivery branch pipe 402 are connected accordingly, and the assembly is completed.
