Description

Technical Field

[0001] The invention relates to the technical field of asphalt mixture production, and in particular to an adjustable modular assembly structure and method based on electromagnetic heating. Background Art

[0002] The fuel energy consumption in the asphalt mixture production process accounts for about 93.3% of the entire asphalt pavement construction process, and the waste gas emission accounts for more than 90%, which is mainly concentrated in the drying and heating of aggregates and the insulation heating of asphalt. The asphalt heating and insulation system uses a thermal oil furnace as the heating source. Thermal oil heating uses high flash point mineral oil heated to a higher temperature as a heat medium, which circulates in the conduit and serpentine tube to heat the asphalt outside the tube. The advantage of this method is that the thermal oil heater used is compact in structure, easy to use, gentle in heating, high in thermal efficiency, easy to automatically control temperature, and heats the asphalt evenly and quickly.

[0003] An electromagnetic heater is a device that converts electrical energy into thermal 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 effects. During the electromagnetic induction heating process, there is no direct contact between the induction coil and the heated metal part. Energy is transferred through electromagnetic induction, which reduces a lot of heat energy loss during conduction. The efficiency is greatly improved, which can reach about 85%. The temperature of metal parts rises quickly, and the resistance of metal parts is small, so a smaller electromotive force can generate a stronger eddy current, more Joule heat is generated, and less heat is dissipated, so the metal parts heat up quickly.

[0004] In the prior art, when heating the 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 multi-asphalt materials, it is necessary to assemble multiple electromagnetic heating modules together. In order to improve the heating efficiency and the heat preservation effect, each electromagnetic heating module is usually installed in a heating box in a compact manner. Therefore, during the heating process, the air circulation between the electromagnetic heating modules is poor, which is not conducive to the heat dissipation of the electromagnetic heating modules. If the heat is not dissipated in time, the internal temperature of the equipment will increase. Excessive temperature will accelerate the aging of components inside the equipment and shorten the service life of the equipment. Summary of the invention

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

[0032] (4) In the present invention, when the electromagnetic heating module needs to be disassembled, the present invention directly drives two groups of adjacent electromagnetic heating modules to move away from each other and reach a certain distance through the adjustment 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.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1-Figure 2 As shown, the present invention is an adjustable modular assembly structure based on electromagnetic heating, including a heating box 1, in which at least one row of electromagnetic heating modules is arranged, and each row of electromagnetic heating modules includes a plurality of groups of electromagnetic heating modules 3 arranged at equal intervals; in this embodiment, two rows of electromagnetic heating modules are arranged in the heating box 1, and each row of electromagnetic heating modules includes five groups of electromagnetic heating modules 3, and correspondingly, six or eight groups of electromagnetic heating modules 3 can also be set in each column, which is not limited to meet the actual heating demand for heat transfer oil.

[0045] In the present embodiment, a group of main oil pipes 102 are symmetrically arranged on both sides of the heating box body 1, and the other end of the main oil pipe 102 is connected to the oil inlet end of the serpentine pipe used for heating the asphalt material through an oil pump, and a main oil return pipe 103 is provided at the bottom of each main oil pipe 102, and the main oil return pipe 103 is connected to the oil outlet end of the serpentine pipe through a circulating pump; specifically, in the present embodiment, after the heat transfer oil is heated by each group of electromagnetic heating modules 3, the oil pump transports the heat transfer oil to the serpentine pipe through the main oil pipe 102 to heat the asphalt material, and then the heat transfer oil in the serpentine pipe is transported to the electromagnetic heating module 3 again through the main return oil pipe 103 for heating by the circulating pump, so as to achieve the effect of circulating heating.

[0046] It also includes an adjustment module, which is used to adjust the distance between two adjacent groups of electromagnetic heating modules 3; it can be explained that after the electromagnetic heating modules 3 are installed in the heating box 1, in the initial state, in order to achieve the effect of rapid heating, the present embodiment can synchronously adjust the groups of electromagnetic heating modules 3 to gather together through the adjustment module to reduce the distance between the two adjacent groups of electromagnetic heating modules 3. On the one hand, the air flow rate of the two adjacent groups of electromagnetic heating modules 3 can be reduced to make the temperature rise faster. On the other hand, heat conduction can be carried out between the two adjacent groups of electromagnetic heating modules 3 through thermal radiation to further improve the heating rate. Correspondingly, when the asphalt material is being heated, in order to improve the heat dissipation efficiency of the electromagnetic heating module 3, the present embodiment drives the electromagnetic heating modules 3 to move away from each other through the adjustment module to increase the air flow rate of the two adjacent groups of electromagnetic heating modules 3, dissipate heat for the electromagnetic heating modules 3, ensure the normal operation of each electromagnetic heating module 3, and improve its service life.

[0047] Example 2

[0048] Based on Example 1, please refer to Figure 3 and Figure 5-Figure 6 Each group of electromagnetic heating modules 3 includes an oil inlet pipe 403 and an oil outlet pipe 4, wherein the oil inlet pipe 403 is connected to the main oil return pipe 103 through the first oil return branch pipe 404 or the second oil return branch pipe 405, and the oil outlet pipe 4 is connected to the main oil pipe 102 through the first oil delivery branch pipe 401 or the second oil delivery branch pipe 402; specifically, the heat transfer oil heated by the electromagnetic heating module 3 first enters the first oil delivery branch pipe 401 or the second oil delivery branch pipe 402 through the oil outlet pipe 4, and then enters the main oil delivery pipe 102, and the reflux heat transfer oil first enters the first oil return branch pipe 404 or the second oil return branch pipe 405 through the main oil return pipe 103, and then enters the oil inlet pipe 403 through the first oil return branch pipe 404 or the second oil return branch pipe 405, so as to be heated again by the electromagnetic heating module 3 later.

[0049] As a further solution of this embodiment, the first oil delivery branch pipe 401 is used to be plugged and matched with the second oil delivery branch pipe 402, and the outer wall of the first oil delivery branch pipe 401 is slidably fitted with the inner wall of the second oil delivery branch pipe 402;

[0050] Correspondingly, the first oil return branch pipe 404 is used to be plugged and matched with the second oil delivery branch pipe 402, and the outer wall of the first oil return branch pipe 404 is slidably fitted with the inner wall of the second oil return branch pipe 405;

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

[0052] For two adjacent groups of electromagnetic heating modules 3, when the oil inlet pipe 403 of one group of electromagnetic heating modules 3 is connected to the first oil return branch pipe 404, and the oil outlet pipe 4 is connected to the first oil delivery branch pipe 401, the oil outlet pipe 4 of the other group of electromagnetic heating modules 3 is limited to being connected to the second oil return branch pipe 405, and the oil outlet pipe 4 is connected to the second oil delivery branch pipe 402, wherein the first oil return branch pipe 404 is plugged in with the second oil return branch pipe 405, and the first oil delivery branch pipe 401 is plugged in with the second oil delivery branch pipe 402 ; It can be explained that when the adjustment module drives the electromagnetic heating modules 3 on both sides to move closer to or away from each other, the electromagnetic heating module 3 can synchronously drive the first oil return branch pipe 404 to slide in the second oil return branch pipe 405, and the first oil delivery branch pipe 401 to slide in the second oil delivery branch pipe 402. At the same time, the first oil return branch pipe 404 and the second oil return branch pipe 405 and the first oil delivery branch pipe 401 and the second oil delivery branch pipe 402 are always in a state of interconnection, 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, the present embodiment directly drives the two adjacent groups of electromagnetic heating modules 3 to move away from each other and reach a certain distance through the adjustment module, so that the first oil return branch 404 is disconnected from the second oil return branch 405, and the first oil delivery branch 401 is disconnected from the second oil delivery branch 402.

[0054] Furthermore, the first oil return branch pipe 404 is also used to be plugged and matched with the main oil delivery pipe 102, and the outer wall of the first oil return branch pipe 404 is slidably fitted with the inner wall of the main oil delivery pipe 102;

[0055] The first oil delivery branch pipe 401 is also used for plugging and matching with the main oil return pipe 103, and the outer wall of the first oil delivery branch pipe 401 is slidably fitted with the inner wall of the main oil return pipe 103; wherein, for each row of electromagnetic heating modules, the oil outlet pipes 4 of the electromagnetic heating modules 3 at both ends are connected to the first oil delivery branch pipe 401, and the oil inlet pipe 403 is connected to the first oil return branch pipe 404; specifically, in the present embodiment, when the regulating module drives each electromagnetic heating module 3 to move, the electromagnetic heating modules 3 located at the both ends, the first oil delivery branch pipe 401 thereof slides on one side of the main oil delivery pipe 102, and the first oil return branch pipe 404 slides on one side of the main oil return pipe 103, so as to realize the transportation of heat transfer oil;

[0056] It should be noted that when the adjustment module drives the electromagnetic heating modules 3 to move synchronously, the movement distance of the electromagnetic heating modules 3 close to the two sides of the heating box 1 is greater than the movement distance of the electromagnetic heating modules 3 close to the inside. Therefore, this embodiment needs to set the lengths of the first oil delivery branch pipe 401 and the first oil return branch pipe 404 of the electromagnetic heating modules 3 at the head and tail ends accordingly to avoid the first oil delivery branch pipe 401 and the main oil delivery pipe 102, as well as the first oil return branch pipe 404 and the main oil return pipe 103 from being separated when the electromagnetic heating modules 3 gather together.

[0057] See also Figure 6 Each group of electromagnetic heating modules 3 includes a metal heating tube 303, which is made of carbon steel or 304 stainless steel, wherein an insulating sleeve 302 is sleeved on the outside of the metal heating tube 303, and the insulating sleeve 302 can be made of ceramic material, and an electromagnetic coil 301 is wound around the outside of the insulating sleeve 302; specifically, in this embodiment, an alternating magnetic field is generated by the electromagnetic coil 301 to cause eddy current to generate heat in the tube wall.

[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, wherein the oil outlet pipe 4 and the oil inlet pipe 403 are fixed to the metal heating pipe 303 by locking nuts, and both are detachable.

[0059] As a further solution of this embodiment, please refer to Figure 3-Figure 4 as well as Figure 6The adjustment module includes a positioning seat 504 fixedly arranged on the oil outlet pipe 4, and also includes a guide rod 5 arranged in the heating box 1. A plurality of guide seats 501 are slidably arranged on the guide rod 5. An adjustment plate 502 is fixedly arranged at the bottom of each guide seat 501. Two groups of adjustment rods 503 are symmetrically arranged at both ends of the adjustment plate 502. Each group 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. Connection, wherein an adjusting electric cylinder 2 is fixedly arranged on the heating box body 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 positions of each electromagnetic heating module 3, the adjusting electric cylinder 2 is started to drive the guide rod 5 to rise and fall in the heating box body 1, and during the lifting process, the guide rod 5 can synchronously drive each electromagnetic heating module 3 to synchronously gather or spread in the heating box body 1 through the guide seat 501 and the adjusting rod 503. During this process, the guide seat 501 synchronously slides on the guide rod 5 to adjust the position accordingly.

[0060] For ease of disassembly, see Figure 4 Each group of second hinged seats 505 includes support plates 507 symmetrically arranged on the positioning seat 504, and a pin shaft 508 is spirally arranged in the support plate 507. The end of the adjusting rod 503 away from the first hinged seat 506 is provided with a through hole for being sleeved on the pin shaft 508. It can be explained that when installing the adjusting rod 503, the through hole of the adjusting rod 503 is first placed between the two groups of support plates 507, and then the pin shaft 508 is passed through the support plate 507 and screwed fixed to the through hole.

[0061] In addition, when installing each electromagnetic heating module 3 in this embodiment, firstly, the guide rod 5 is driven downward by adjusting the electric cylinder 2 until the main oil delivery pipe 102 and the main oil return pipe 103 on both sides can accommodate a plurality of groups of oil delivery branch pipes and oil return branch pipes to be installed, and then the first oil delivery branch pipe 401 of the electromagnetic heating modules 3 at both ends are plugged and positioned with the main oil delivery pipe 102 and the first oil return branch pipe 404 with the main oil return pipe 103, and then the positioning seats 504 of the electromagnetic heating modules 3 at both ends are connected with the adjusting rod 503, and then the electromagnetic heating modules 3 in the middle are placed in the corresponding positions, Then connect the positioning seat 504 to the adjusting rod 503 respectively, and finally drive the guide rod 5 to rise by adjusting the electric cylinder 2. During the rising process, the guide rod 5 can synchronously drive the electromagnetic heating modules 3 to gather synchronously 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 correspondingly plugged in, and the first oil delivery branch pipe 401 and the second oil delivery branch pipe 402 are correspondingly plugged in to realize the installation of each electromagnetic heating module 3. The steps for disassembly are opposite to those for installation. The electromagnetic heating module 3 of this embodiment is very convenient to disassemble and assemble.

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

[0063] An assembling method of an adjustable modular assembly structure based on electromagnetic heating comprises the following steps:

[0064] S1. Please refer to Figure 2-Figure 4 , adjust the electric cylinder 2 to drive the guide rod 5 to descend until the main oil delivery pipe 102 and the main oil return pipe 103 on both sides can accommodate several groups of oil delivery branch pipes and oil return branch pipes to be installed;

[0066] S3, placing each electromagnetic heating module 3 in the middle position at a corresponding position, and then connecting its positioning seat 504 to the adjustment rod 503 respectively;

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