Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically a microwave heating device for the vapor phase modification of hydrophobic and oil-absorbing materials. Background Technology

[0002] Vapor-phase modification of hydrophobic and oil-absorbing materials can be achieved through microwave heating. Compared with traditional heating methods, microwave heating has advantages such as uniform heating, fast speed, and high energy conversion efficiency. Vapor-phase modification typically uses gaseous reactants (such as gaseous fluorides, ammonia, chlorine, etc.) to react with the material surface to improve the material's hydrophobicity, high-temperature resistance, or other properties.

[0003] For example, the national authorized patent announcement number CN207753887U discloses a microwave heating device, including a microwave cavity for containing the material to be heated, a microwave generator and microwave tube for emitting microwaves into the microwave cavity, and a duct or vent for venting the gas generated in the microwave cavity during microwave heating. The side wall of the microwave heating device includes a venting window, which is formed using a metal support frame and a metal foil with a thickness of less than 0.2 mm. More than 30% of the side wall area of ​​the microwave cavity is occupied by the venting window. During normal microwave heating, the metal foil in the venting window isolates the microwaves within the microwave cavity, and automatically ruptures to release pressure and prevent explosion when the pressure inside the microwave cavity becomes too high. This invention provides a good venting effect for microwave heating, eliminating concerns about the significant safety issues associated with using microwave ovens to heat and dry flammable and explosive substances such as fireworks and pharmaceuticals.

[0004] However, the aforementioned microwave heating device cannot separate the material during the process of conveying it into the microwave cavity for heating to prevent it from piling up in one place. The accumulation of material will restrict the airflow or microwave transmission, affecting the uniform distribution of heat. Utility Model Content

[0005] The purpose of this invention is to provide a microwave heating device for the vapor phase modification of hydrophobic and oil-absorbing materials, so as to solve the problem mentioned in the background art that the materials cannot be separated to avoid the materials accumulating in one place during the process of conveying materials into the microwave cavity for heating.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A microwave heating device for vapor-phase modification of hydrophobic and oil-absorbing materials includes: a U-shaped cylinder, on both sides of the upper surface of the U-shaped cylinder, connecting plates are fixedly installed, one end of the inner side of the two sets of connecting plates is embedded, two sets of transmission columns are rotatably installed between the two sets of connecting plates, two sets of transmission belts are fitted on the outer surface of the two sets of transmission columns, the two sets of transmission belts are located in the embedded grooves of the connecting plates, a drag bar is fixedly installed between the two sets of transmission belts, a top cover is fixedly installed on the upper surface of the U-shaped cylinder, a magnetron is fixedly installed on the lower inner surface of the top cover, an installation cover is connected to one end of the top cover, and a hydrophobic and oil-absorbing material pushing mechanism is rotatably installed inside the installation cover.

[0008] Preferably, a first geared motor is fixedly installed at one end of the connecting plate, and the first geared motor is fixedly connected to one of the sets of transmission columns.

[0009] Preferably, a U-shaped aluminum plate is fixedly installed inside the U-shaped cylinder, and the U-shaped aluminum plate is flush with the magnetron.

[0010] Preferably, the hydrophobic and oil-absorbing material pushing mechanism includes a rotating plate, which is rotatably installed on the lower inner surface of the mounting cover. Guide plates are fixedly installed on both sides of the mounting cover, so that the two sets of guide plates are spliced ​​together to form a figure-eight-shaped guide plate. The guide plates slide against the upper surface of the drag bar.

[0011] Preferably, a slide bar is fixedly installed at one end of the rotating plate, an eccentric shaft is slidably installed in the slide bar, the eccentric shaft is fixedly installed on the lower surface of the eccentric wheel, the eccentric wheel is rotatably installed in the mounting cover and its upper surface is fixedly connected to the output shaft of the second reduction motor, and mounting plates are fixedly installed on both sides of the second reduction motor, the mounting plates are fixedly installed on the upper surface of the mounting cover.

[0012] Preferably, the eccentric shaft is driven by the second reduction motor to slide and push the rotating plate at the slide bar opening, so that the rotating plate can drive the guide plate to swing back and forth within the mounting cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the top cover, first reduction motor, transmission belt, drag bar, and hydrophobic and oil-absorbing material pushing mechanism, when heating materials, the first reduction motor can be started to drive the transmission belt mounted on the outer surface of the transmission column to rotate, which in turn drives the drag bar fixedly installed between them. Then, the staff can pour the materials into the upper surface of the drag bar and convey them into the mounting cover and the top cover in sequence. During the process of the materials being conveyed into the mounting cover, they are concentrated and guided by the hydrophobic and oil-absorbing material pushing mechanism that swings back and forth inside the mounting cover. With the back-and-forth swing and the conveying of the drag bar, the materials are dispersed in the top cover and microwave heated by the magnetron. During the process of the materials being pushed, the materials slide within the gap between the drag bars. As the materials are pushed and dispersed in the top cover, they can be distributed relatively evenly. The even distribution of materials can ensure that each part of the material can fully contact the heating source, avoiding local overheating or underheating. This helps the modification reaction to occur evenly in all parts of the material, thereby improving the consistency of product quality.

[0015] 2. Through the design of the second reduction motor, eccentric wheel, eccentric shaft, rotating plate, sliding bar opening, and guide plate, when the material conveyed into the mounting cover is divided, the second reduction motor can be started to drive the eccentric shaft on the lower surface of the eccentric wheel to slide and push the rotating plate to swing back and forth in the mounting cover. This allows the rotating plate to drive the guide plates at both ends to swing back and forth against the surface of the towing rod. The figure-eight-shaped guide plate formed by the splicing of the two sets of guide plates can concentrate and guide the material. Combined with the back-and-forth swing and the conveying of the towing rod, the material is dispersed and evenly distributed on the upper surface of the towing rod and conveyed into the top cover for microwave heating by the magnetron. The evenly distributed material allows the microwave energy emitted by the magnetron to be absorbed more effectively by the material, which helps to improve the energy utilization efficiency of the entire material heating process. At the same time, it can prevent the material from clogging the channel due to accumulation during the conveying process, and ensure that the material enters the top cover smoothly to receive heating.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This embodiment provides the following technical solution:

[0024] like Figures 1-4 As shown, a microwave heating device for vapor-phase modification of hydrophobic and oil-absorbing materials includes: a U-shaped cylinder 101, with connecting plates 102 fixedly installed on both sides of the upper surface of the U-shaped cylinder 101. The inner ends of the two sets of connecting plates 102 are embedded. Two sets of transmission columns 103 are rotatably installed between the two sets of connecting plates 102. Two sets of transmission belts 104 are fitted on the outer surfaces of the two sets of transmission columns 103. The two sets of transmission belts 104 are located in the embedded grooves of the connecting plates 102. A drag bar 109 is fixedly installed between the two sets of transmission belts 104. A top cover 1 is fixedly installed on the upper surface of the U-shaped cylinder 101. A magnetron 107 is fixedly installed on the lower inner surface of the top cover 1. One end of the top cover 1 is connected to an installation cover 106. A hydrophobic and oil-absorbing material pushing mechanism 2 is rotatably installed inside the installation cover 106.

[0025] The first geared motor 105 is fixedly installed at one end of the connecting plate 102, and the first geared motor 105 is fixedly connected to one of the transmission columns 103.

[0026] A U-shaped aluminum plate 108 is fixedly installed inside the U-shaped cylinder 101, and the U-shaped aluminum plate 108 is flush with the magnetron 107.

[0027] Through the design of the top cover 1, the first reduction motor 105, the transmission belt 104, the drag bar 109, and the hydrophobic and oil-absorbing material pushing mechanism 2, when the material is heated, the first reduction motor 105 can be started to drive the transmission belt 104, which is mounted on the outer surface of the transmission column 103, to rotate. This allows the transmission belt 104 to drive the drag bar 109, which is fixedly installed therebetween, to transmit power. Subsequently, the material can be poured into the upper surface of the drag bar 109 and then sequentially conveyed into the mounting cover 106 and the top cover 1. During the process of conveying the material into the mounting cover 106, it is irritated by the hydrophobic and oil-absorbing material that swings back and forth within the mounting cover 106. The material pushing mechanism 2 centrally guides the flow, and in conjunction with the reciprocating oscillation and the conveying of the drag rod 109, it disperses the material within the top cover 1 so that it can be microwave heated by the magnetron 107. During the pushing process, the material slides within the gap between the drag rods 109. As the material is pushed and dispersed within the top cover 1, it can achieve a relatively uniform distribution. The uniform distribution of the material ensures that each part of the material can fully contact the heating source, avoiding local overheating or underheating. This helps the modification reaction to occur uniformly in all parts of the material, thereby improving the consistency of product quality.

[0028] like Figure 5 As shown, the hydrophobic and oil-absorbing material pushing mechanism 2 includes a rotating plate 204, which is rotatably installed on the lower inner surface of the mounting cover 106. Guide plates 207 are fixedly installed on both sides of the mounting cover 106, so that the two sets of guide plates 207 are spliced ​​together to form a figure-eight-shaped guide plate. The guide plates 207 slide against the upper surface of the drag bar 109.

[0029] Among them, a slide bar opening 205 is fixedly installed at one end of the rotating plate 204, and an eccentric shaft 203 is slidably installed in the slide bar opening 205. The eccentric shaft 203 is fixedly installed on the lower surface of the eccentric wheel 202. The eccentric wheel 202 is rotatably installed in the mounting cover 106 and its upper surface is fixedly connected to the output shaft of the second reduction motor 201. Mounting plates 206 are fixedly installed on both sides of the second reduction motor 201, and the mounting plates 206 are fixedly installed on the upper surface of the mounting cover 106.

[0030] The eccentric shaft 203 is driven by the second reduction motor 201 to slide and push the rotating plate 204 through the slide bar opening 205, thereby enabling the rotating plate 204 to drive the guide plate 207 to swing back and forth within the mounting cover 106.

[0031] Through the design of the second reduction motor 201, eccentric wheel 202, eccentric shaft 203, rotating plate 204, sliding groove 205, and guide plate 207, when the material conveyed into the mounting cover 106 is divided, the second reduction motor 201 is started to drive the eccentric shaft 203 on the lower surface of the eccentric wheel 202 to slide and push the rotating plate 204 to swing back and forth in the mounting cover 106 within the sliding groove 205. This allows the rotating plate 204 to drive the guide plates 207 at both ends to adhere to the surface of the drag bar 109 and swing back and forth. The eight-section structure formed by the splicing of the two sets of guide plates 207... The T-shaped guide plate can concentrate and guide the material, and together with the reciprocating swing and the conveying of the drag bar 109, it can disperse the material, so that the material can be evenly distributed on the upper surface of the drag bar 109 and conveyed into the top cover 1 to be microwave heated by the magnetron 107. The evenly distributed material allows the microwave energy emitted by the magnetron 107 to be absorbed by the material more effectively, which helps to improve the energy utilization efficiency of the entire material heating process. At the same time, it can prevent the material from clogging the channel due to accumulation during the conveying process, and ensure that the material enters the top cover 1 smoothly to be heated.

[0032] Based on the above technical solution, the working steps of this solution are summarized as follows: When heating the material, the first reduction motor 105 can be started to drive the transmission belt 104 mounted on the outer surface of the transmission column 103 to rotate, thereby enabling the transmission belt 104 to drive the fixedly installed drag bar 109 to perform transmission. Subsequently, the staff can pour the material into the upper surface of the drag bar 109 and then transport it into the mounting cover 106 and the top cover 1 in sequence. During the process of the material being transported into the mounting cover 106, the second reduction motor 201 can be started to drive the eccentric wheel 202 downward. The eccentric shaft 203 on the surface slides and pushes the rotating plate 204 to oscillate back and forth in the mounting cover 106 within the slide bar 205. This allows the rotating plate 204 to drive the guide plates 207 at both ends to oscillate back and forth against the surface of the drag rod 109. The figure-eight-shaped guide plate formed by the splicing of the two sets of guide plates 207 can concentrate and guide the material. Combined with the reciprocating oscillation and the conveying of the drag rod 109, the material is dispersed and evenly distributed on the upper surface of the drag rod 109 and conveyed into the top cover 1 for microwave heating by the magnetron 107.

[0033] In summary: the material can be pushed and distributed before being heated, so that the material can be evenly distributed on the upper surface of the towing rod 109 and transported into the top cover 1 to be microwave heated by the magnetron 107. The evenly distributed material allows the microwave energy emitted by the magnetron 107 to be absorbed more effectively by the material, which helps to improve the energy utilization efficiency of the entire material heating process. At the same time, it can prevent the material from clogging the channel due to accumulation during the transportation process, and ensure that the material enters the top cover 1 smoothly to be heated.
