Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic heating air ducts, in particular to a full-contact electromagnetic heating air duct. Background Art

[0002] Electromagnetic heating duct is a technology that uses electromagnetic radiation to heat air or heat-conducting media. In this system, electromagnetic energy is transmitted to the working material (such as air, solid or liquid) through electromagnetic waves or high-frequency oscillations to heat it rapidly. This method is usually used to heat materials or media quickly and efficiently, such as for heating materials or fluids on industrial production lines. Electromagnetic heating ducts can achieve precise temperature control and efficient energy conversion, which helps to improve production efficiency.

[0003] Through the above content and combined with the performance of the electromagnetic air duct during actual operation, it is known that the existing electromagnetic heating air duct still has certain shortcomings. During the operation, the existing electromagnetic heating air duct only uses the electromagnetic coil outside the air duct for heating. Since the heating length of the electromagnetic coil is limited and the air flow in the air duct is large, this will cause the incoming air to be heated for too short a time, so that the air cannot contact the heat source in a short time. Due to insufficient contact, the heating effect of the air duct will be significantly discounted, and after long-term operation of the air duct, its inner wall will be attached to more impurities brought in by the air, which will also reduce the electromagnetic conduction effect during heating;

[0004] Therefore, the present application proposes a full-contact electromagnetic heating air duct. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0024] In order to solve the technical problems in the background technology, a full contact electromagnetic heating air duct is provided as follows:

[0025] Combination Figure 1-Figure 4 As shown, the utility model provides a full contact electromagnetic heating air duct, including an air duct body 1, the air duct body 1 is equipped with an air filter chamber 6, the air filter chamber 6 is equipped with a filter assembly 8, the front side of the air filter chamber 6 is docked with a pull-out assembly 7, and the air filter chamber 6 is limitedly connected to the air duct body 1 through the pull-out assembly 7, the air duct body 1 on the rear side of the air filter chamber 6 is fixedly installed with a partition 5, the back side of the partition 5 is fixedly installed with six groups of distributed heating assemblies 4, and the rear end of the distributed heating assembly 4 is fixedly installed with a connected secondary heating assembly 3;

[0026] The airflow is conducted through the air duct main body 1, and at the same time as entering the air duct main body 1, impurities in the air are filtered through the air filter chamber 6. This not only ensures the cleanliness of the inner wall of the subsequent tube group and avoids the scaling of impurities on the inner wall of the tube group, but also ensures that the heating components are not affected during heat transfer. Through the cooperation between the pulling and pulling components 7 and the air filter chamber 6, personnel only need to complete the rapid separation between the air filter chamber 6 and the air duct main body 1 by pulling and pulling, and it is also more convenient and quick to clean and replace the filter components. The air entering the air duct can be differentiated and heated multiple times through the distributed heating components 4. This not only ensures that the air is fully contacted and heated inside the air duct, but also increases the heating process of the air. The secondary heating component 3 can not only be used to re-collect the differentiated air, but also to reheat the collected air, so that the air can be fully contacted and heated, thereby ensuring the heating effect of the air duct.

[0027] The secondary heating component 3 includes a built-in metal sleeve 31, a second electromagnetic heating coil 32, a sealing plate 33, and an air guide cavity 34; the chemical heating component 4 includes a ceramic air guide duct 41, a dispersed branch pipe 42, and a first electromagnetic heating coil 43. A partition 2 35 is fixedly installed inside the air duct main body 1, and the partition 2 35 is located behind the partition 1 5. The air guide cavity 34 is fixedly installed on the back of the partition 2 35. The sealing plate 33 is fixedly installed on the back of the air guide cavity 34. Three groups of built-in metal sleeves 31 are fixedly installed on the inner side of the sealing plate 33. The second electromagnetic heating coil 32 is butt-jointedly installed in the built-in metal sleeves 31. Six groups of connected ceramic air guide ducts 41 are fixedly installed on the back of the partition 1 5, and the first electromagnetic heating coil 43 is mounted on the ceramic air guide duct 41. A plurality of dispersed branch pipes 42 are butt-jointedly installed at the rear end of the ceramic air guide duct 41, and the ceramic air guide duct 41 is connected to the air guide cavity 34 through the dispersed branch pipes 42.

[0028] The air entering the air duct will first enter the ceramic air duct 41 for a differentiation, and then be quickly heated by the first electromagnetic heating coil 43. The heated air will then enter the dispersion branch 42 again for a secondary differentiation. The purpose of the secondary differentiation is to ensure that when entering the air guide cavity 34, it can fully contact the built-in metal sleeve 31 in the air guide cavity 34, to ensure that the built-in metal sleeve 31 is heated by the second electromagnetic heating coil 32 for sufficient heat transfer again, and then return to the air duct main body 1 for the guiding operation.

[0029] The pull-out assembly 7 includes a pull-out rod 71 and a guide rail 72. Two sets of guide rails 72 are fixedly installed at the top and bottom of the air duct body 1, and the guide rails 72 are slidably connected to the air filter chamber 6. The front of the air filter chamber 6 is docked with the pull-out rod 71; the filter assembly 8 includes a HEPA filter layer 83 and a fiber mesh filter layer 84. The interior of the air filter chamber 6 is respectively equipped with the HEPA filter layer 83 and the fiber mesh filter layer 84, and the fiber mesh filter layer 84 is located in front of the HEPA filter layer 83;

[0030] The air entering the air duct body 1 will first be filtered through the HEPA filter layer 83 and the fiber mesh filter layer 84 to remove foreign particles in the air. When the HEPA filter layer 83 and the fiber mesh filter layer 84 need to be replaced regularly, the staff can pull the pull rod 71 to pull the air filter chamber 6 as a whole, and the air filter chamber 6 can complete its own conduction through the cooperation of the guide rail 72. Embodiment 2

[0031] like Figure 1 and Figure 2 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0032] In this embodiment, docking ports 2 are fixedly installed at both ends of the air duct body 1 , and assembly ports 21 for assembly are disposed at four corners of the docking ports 2 .

[0033] During this period, the personnel complete the docking with the external inlet branch pipe through the docking interface 2, and the docking interface 2 is frame-shaped. After the docking is completed, the personnel can cooperate with the external components through the assembly port 21 to complete the installation connection between the air duct main body 1 and the external pipe group.

[0034] In this embodiment, the pull-out assembly 7 also includes a plug-in plate 73 and a limiting cap 74. The end of the pull-out rod 71 is docked with the plug-in plate 73, and the plug-in plate 73 is provided with a lifting mouth 731 that cooperates with the pull-out rod 71. The lifting mouth 731 is penetrated by the pull-out rod 71, and the end of the pull-out rod 71 is docked with a limiting cap 74 for limiting the plug-in plate 73. The bottom of the air duct main body 1 is provided with a plug interface 11 that docks and cooperates with the plug-in plate 73.

[0035] When the air filter chamber 6 is in operation, in order to ensure the stability of the air filter chamber 6 during operation, the personnel can insert the plug-in plate 73 into the plug-in port 11. Since the end of the pull-out rod 71 is limited by the limit cap 74, the air filter chamber 6 will be limited by the plug-in relationship between the pull-out rod 71, the plug-in plate 73, and the plug-in port 11, thereby ensuring that it can be stably assembled in the air duct main body 1. Embodiment 3

[0036] like Figure 1-Figure 4As shown, based on the above embodiment, this embodiment further provides the following contents:

[0037] In this embodiment, an air inlet end and an air outlet end are respectively provided on the air filter chamber 6, a mesh window 61 for guiding air is fixedly installed at the port of the air inlet end, and the end of the pull rod 71 is fixedly installed on the mesh window 61, and two sets of guide openings 611 are provided at the top and bottom of the mesh window 61, and the guide openings 611 are slidably connected to the guide rail 72.

[0038] During this period, the air will first enter the air filter chamber 6 through the mesh window 61 at the air inlet end, and be filtered by the filter component in the air filter chamber 6;

[0039] There is a sliding relationship between the guide opening 611 and the guide rail 72 . When a person needs to pull the air filter chamber 6 , the air filter chamber 6 can assist itself in moving smoothly through the sliding cooperation between the guide opening 611 and the guide rail 72 .

[0040] In this embodiment, the length, width and height of the air guiding cavity 34 are smaller than the partition 2 35 , and the four sides of the air guiding cavity 34 are provided with interconnected air guiding ports 341 , and the wind in the air guiding cavity 34 is guided into the air duct body 1 through the air guiding ports 341 .

[0041] Since the length, width and height of the air guiding cavity 34 are smaller than the partition plate 35 , there is a flow guiding space between the air guiding cavity 34 and the air duct body 1 , so it will not affect the air at the air guiding port 341 from entering the air duct body 1 .

[0042] In this embodiment, the filter assembly 8 also includes a self-closing air guide plate 81 and a pin shaft 82. The top of the air outlet end is docked with a pin shaft 82, and the pin shaft 82 is mounted with a self-closing air guide plate 81 for rich sealing. The self-closing air guide plates 81 and 82 are movably connected.

[0043] The self-closing air deflector 81 has two states;

[0044] First, when there is no airflow passing through the air duct body 1, the self-closing air guide plate 81 will droop under the action of gravity. The purpose of the droop is to isolate more effectively and prevent external air from entering the interior during non-operation period;

[0045] Secondly, when air guiding operation is performed in the air duct main body 1, the self-closing air guide plate 81 is affected by the airflow, and the self-closing air guide plate 81 will turn up with the cooperation of the pin shaft 82 to ensure the air guiding operation.

[0046] The working principle and use process of this utility model:

[0047] During this period, the personnel complete the connection with the external inlet and outlet pipes through the connection port 2, and the connection port 2 is frame-shaped. After the connection is completed, the personnel can cooperate with the external components through the assembly port 21 to complete the installation connection between the air duct body 1 and the external pipe group;

[0048] The air entering the air duct body 1 will first be filtered through the HEPA filter layer 83 and the fiber mesh filter layer 84 to remove foreign particles in the air. When the HEPA filter layer 83 is filtered, the air entering the air duct will first enter the ceramic air guide pipe 41 for a differentiation, and then be quickly heated by the first electromagnetic heating coil 43. The heated air will enter the dispersion branch pipe 42 again for a secondary differentiation. The purpose of the secondary differentiation is to ensure that when entering the air guide cavity 34, it can fully contact with the built-in metal sleeve 31 in the air guide cavity 34, so as to ensure that the built-in metal sleeve 31 is heated by the second electromagnetic heating coil 32 and then fully transfers heat again, and then returns to the air duct body 1 for the guiding operation;

[0049] When the fiber mesh filter layer 84 needs to be replaced regularly, the staff can pull the pull rod 71 to pull the air filter chamber 6 as a whole, and the air filter chamber 6 can slide with the guide port 611 and the guide rail 72 to assist itself in moving smoothly, and then the staff can replace it.
