[0001] INDUSTRIAL MICROWAVE METAL MELTING OVEN

[0002] Technical Field:

[0003] This invention; It is about a multi-magnetron industrial microwave metal melting oven, which provides energy saving for metal melting, sintering and fruit drying systems, is suitable for human health, solves the magnetron heating problem, can transfer high energy to the oven center, and has a user-friendly programming interface.

[0004] State of the Art:

[0005] Industrial microwave ovens are needed in metal melting, sintering and fruit drying systems. This need is increasing especially for applications where it is desired to reach high temperatures quickly and with low power consumption. This need is currently met with induction melting ovens. According to this method, it is necessary to develop microwave ovens that can reach higher temperatures faster and to create an alternative system. Microwave ovens used in these areas are both large in size and cannot reach high temperatures due to design errors.

[0006] As the magnetron number increases, the power density emitted by the system increases and this is not suitable for human health. This requires a special design for multimagnetron systems. Existing systems are not designed in terms of energy consumption, which creates the need for efficient systems.

[0007] Magnetrons overheat and in existing systems this is achieved by conventional cooling systems such as water, air and fan systems. These solutions cause additional costs. Connecting a large number of magnetrons in a oven creates problems in the point of transferring the energy to the material at the maximum value. In addition, when the magnetron positions are not well chosen, they heat each other and this reduces the efficiency extremely. In order to solve this problem, in the current known situation, magnetrons are placed at 90 degrees to each other instead of facing each other. However, in this case, it is not effective when the oven size and waveguide size are not fully adjusted. Appropriate dimensional values have been optimized to fully solve these problems.

[0008] In the melting methods described in the state of the art, fossil-based methods both take a very long time to melt and are not a preferred method in terms of energy efficiency. Induction melting ovens, which are another method, require the production of multiwinding and large-sized ovens in order to reach the desired high temperatures, since they consist of coil windings. As the windings increase, the temperature formed in the coil will increase, so the losses increase and the efficiency decreases.

[0009] Since the metal melting systems made with the microwave system are not designed properly, they are large in size and are not ergonomic. In addition, high temperatures cannot be reached due to the fact that the magnetrons are not placed in the most ideal way. Even in existing systems that can reach low and medium temperatures, more than 4 magnetrons are needed.

[0010] Since the waveguides of microwave systems are not designed according to the oven and the system, the efficiency decreases. As the number of magnetrons increases in multimagnetron systems, the radiated power density also increases. Magnetrons get extremely hot and can run for about 2 minutes without any cooling system. Magnetron heating systems require a power of 0.8kW to IkW. As more magnetrons are added to the system, this amount increases as the number of magnetrons. Existing systems are not sufficient for the user to set the system at the desired values.

[0012] “An Industrial Microwave Oven Multi -Magnetron Centralized Power Supply System” is described in the utility model application with the number CN204836638U. The invention relates to a power supply system, and the microwave oven, concentrating on many magnetrons of the industry, is provided with the main power supply, negative pole load high voltage transmission line, filament current transmission line, and high power capacity positive pole grounding wire, magnetron protection circuit. The utility model explains that the negative pole can produce negative high voltage and filament voltage, when the sufficient power sum ranges are stable, the negative pole, the positive pole and the filament of the plurality of magnetrons of industry microwave equipment are connected in parallel with the negative pole load high voltage transmission line, the positive pole grounding wire and the filament voltage transmission line respectively. During the short circuit, the magnetron protection circuit starts, the negative pole between the magnetron cathode and the positive pole interrupts the negative high voltage, when the magnetron heater turns on the circuit, the magnetron protection circuit has started, the magnetron is Decoupling the filament current. The negative pole negative high voltage of the system output and the regulation of the filament voltage continue in the main power supply, so the system has a simple structure, uses the high advantage of flexibility and reliability, has significant use value in many magnetron microwave equipment fields. In the above-mentioned applications, an industrial microwave oven is disclosed. The existing applications do not allow magnetrons to be operated at different numbers, as there is no control system. For this reason, overheating occurs and is disadvantageous.

[0013] As a result, a new technology is needed that can overcome the above-mentioned disadvantages, reach high temperatures for short periods, occupy less space due to its design features, reach higher temperatures with fewer magnetrons using 4 magnetrons, energy efficiency is high thanks to the magnetron layout and waveguide design, the S21 parameter of the waveguide is -177dB, the system has an average power density of 0.37 mW / cm2, which has appropriate values for human health.

The waveguide (1) with the mounted magnetron is placed on the mounting part in the oven body (3). Functions of this element; It transfers the electromagnetic energy coming from the magnetron to the oven center and provides the mounting of the magnetron to the oven. One function is to prevent electromagnetic energies from other magnetrons from reaching the magnetron above it.

Thanks to the dimensions, shape and distance from the oven center of these connection points; Electromagnetic waves coming to the oven are focused on the oven center. Heating of magnetrons and electromagnetic leakage are prevented. The element is preferably produced with one of the materials such as aluminum, iron and steel.

[0035] Control System: It is the part that organizes the user to go to the desired temperature in the desired time. Thanks to this section, the user can specify and apply parameters such as whether the 4 magnetron will work, when it will work, when it will stop, and how long it will work. In addition, this element provides savings by organizing energy savings and also prevents magnetron heating. In order to do this, when 4 magnetrons are not operated at the same time, it transfers the energy to 4 magnetrons in periods.

[0036] The control system contained in the product of the invention; the user interface where the temperature value of the oven, the operating time, the number of magnetrons to work, the amount of energy to be given to the system are controlled and various parameters are entered; It includes a processor that transfers energy to 4 magnetrons according to user parameters and in line with the information coming from the temperature probe integrated into the system. Here, the energy coming to the magnetron is transferred to the material in the center of the oven through the waveguide (1). A specially designed waveguide (1) and oven body (3) are used so that the energy transfer is focused in the center and does not reach the other waveguides (1). Thanks to the oven design, a suitable environment for human health is provided. When the temperature value measured with the heat probe located at the bottom of the oven reaches the desired value, the processor included in the system turns off the oven and the user is informed.
