[0005] Prior to this, although there have been some patents attempting to improve microwave heating technology, they either failed to completely solve the problem of uneven heating or still had much room for improvement in energy saving and environmental protection. Therefore, the automated industrial microwave heating device proposed in the present invention has obvious technical innovation and practical value, and is expected to open up new prospects for the application of microwave heating technology in the industrial field.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0026] The utility model provides Figure 1An automated industrial microwave heating device is shown, comprising an introduction funnel 1, the lower end of which is connected to a heating barrel 2, and the upper end of the heating barrel 2 is in an inverted cone shape and the lower end is in a cylindrical shape, the object to be heated is introduced into the heating barrel 2 through the introduction funnel 1, a plurality of evenly distributed microwave generators 3 are arranged inside the side wall of the heating barrel 2, and the object to be heated inside the heating barrel 2 can be evenly heated by the plurality of microwave generators 3, the outer side of the lower end of the heating barrel 2 is connected to a plurality of export switches 4 for controlling the blocking and export of the heated object, the lower ends of the plurality of export switches 4 are all connected to a gathering pipe 6 through an export pipe 5, and the gathering pipe 6 is located directly below the heating barrel 2 for collecting and guiding away the heated object, the upper side of the left end of the heating barrel 2 is connected to a gas treatment box 7 for dust removal and dehumidification, and the lower side of the left end of the heating barrel 2 is fixedly connected to a control cabinet 8 for controlling the operation and stop of the microwave generator 3, the export switch 4 and the gas treatment box 7, as well as other electrical operations inside the heating barrel 2.

[0027] Preferably, the object to be heated is introduced into the interior of the heating barrel 2 through the introduction funnel 1, and the multiple microwave generators 3 are turned on through the control cabinet 8 for heating. Since the multiple microwave generators 3 are evenly distributed inside the heating barrel 2, the object to be heated can be evenly heated. At the same time, the control cabinet 8 controls the gas treatment box 7 to remove dust and dehumidify the upper end of the heating barrel 2. Since the upper end of the heating barrel 2 is in an inverted cone shape, the heated steam and the heated dust will gather toward the inverted cone edge of the top of the heating barrel 2. At this time, the gas treatment box 7 can suck the heated steam and the heated dust into the interior for removal, thereby ensuring the cleanliness of the interior of the heating barrel 2 and improving the drying efficiency of the heated object. After the heating is completed, the control cabinet 8 controls the export switch 4 to open and export the heated object, and finally gather it into the collection pipe 6 for guidance.

[0028] like Figure 2 and Figure 3 As shown, a pre-rotating disk 9 is rotatably connected to the inner wall of the lower end of the heating barrel 2, and the pre-rotating disk 9 is located between the connection ports of the multiple export switches 4 and the heating barrel 2, so as to pre-rotate the heated object. The lower end of the pre-rotating disk 9 is connected to a motor 10 through a rotating shaft, and the motor 10 is located at the center of the lower end of the heating barrel 2, and is used to provide power to the pre-rotating disk 9 and the spiral flap 11. The rotating shaft passes through the interior of the center of the lower end of the heating barrel 2, and the upper end of the pre-rotating disk 9 is fixedly connected to the spiral flap 11, and the spiral flap 11 is a conical spiral setting with a small upper part and a large lower part, so as to flip the heated object inside out.

[0029] Preferably, during the heating process of the heated object, since the heated object is accumulated inside the heating barrel 2, the external heating efficiency of the heated object is greater than the internal heating efficiency, which easily causes the outside to burn, while the inside is not heated well, and the heating efficiency is reduced. At this time, the motor 10 drives the spiral flap 11 to rotate clockwise, pushing the heated object inside the lower end of the accumulated heated object upward and flowing from the upper end to the outside, and the heated object outside the lower end will enter the lower end of the heating barrel 2 under the pushing of the heated object at the upper end, so that the accumulated heated object can circulate inside and outside, which can not only heat the heated object evenly, but also improve the heating efficiency and prevent the heated object from burning.

[0030] like Figure 4 and Figure 5 As shown, a gas processing channel 12 is provided on the upper side of the gas processing box 7, and the right end of the gas processing channel 12 is connected to the interior of the heating barrel 2 for introducing dust and water vapor. An air guide fan 13 is fixedly connected to the inside of the gas processing channel 12 through a connecting rod for driving the air flow so that dust and water vapor are sucked in from the right end of the gas processing channel 12. A filter element 14 is inserted into the rear side of the upper end of the gas processing box 7 for filtering and absorbing dust and water vapor. A gas return channel 15 is provided on the lower side of the gas processing box 7. The left end of the gas return channel 15 is connected to the left end of the gas processing channel 12, and the right end of the gas return channel 15 is connected to the interior of the heating barrel 2 for exporting the treated gas.

[0031] Preferably, when the object to be heated is heated, the moisture inside is heated to become water vapor and flows upward, and in the process of turning the object to be heated, the dust inside the object to be heated will be lifted up and float up due to the heat. At this time, the gas treatment box 7 sucks the heated dust and heated water vapor from the right end of the gas treatment channel 12 for treatment through the rotation of the air guide fan 13. Since the filter element 14 is inserted into the gas treatment channel 12 and is located on the right side of the air guide fan 13, the filter element 14 can process the inhaled gas and filter and absorb the dust and water vapor in the inhaled gas. , and then the gas introduced into the lower side through the left side is guided back to the inside of the channel 15, and finally flows back to the inside of the heating barrel 2, which can not only clean the inside of the heating barrel 2, but also prevent water vapor from entering the inside of the heated object again, thereby improving the heating efficiency. At the same time, the treated gas flows back to the inside of the heating barrel 2, which can effectively prevent the heat loss inside the heating barrel 2. Moreover, since the filter element 14 is inserted into the gas processing channel 12 from the right side of the upper end of the gas processing box 7 and a plug-in handle is provided, the filter element 14 can be replaced in time to ensure the processing capacity of the inhaled gas.

[0032] Finally, it should be noted that the above is only a preferred embodiment 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 make equivalent substitutions for some of the technical features therein.
