Description

Technical Field

[0001] The utility model relates to an electromagnetic heating charcoal calcining device, belonging to the technical field of Chinese medicinal material production. Background Art

[0002] Carbonization involves calcining medicinal materials into charcoal under high-temperature, oxygen-deficient conditions. This method is suitable for calcining medicinal materials with a loose or light texture that easily carbonizes during charcoaling. Most existing calcining machines fail to maintain a tight seal, easily burning and turning the materials into ash during charcoaling. Furthermore, medicinal materials are stacked directly in the calcining container, resulting in uneven heating inside and outside during charcoaling, leading to uneven carbonization of the medicinal materials. Some calcining machines allow for stirring during the calcination process. While this ensures uniform heating of the medicinal materials, the resulting charcoalized medicinal materials are brittle, easily break during stirring, and do not meet the required appearance.

[0005] A heat-insulating layer is provided between the calcining cylinder and the heating element, and the heat-insulating layer surrounds the outer periphery of the calcining cylinder.

[0006] The calcining cylinder is connected to a one-way pressure relief valve, a vent valve and a temperature measuring component.

[0007] The tray includes a base, side panels are arranged around the base, upper support columns are arranged at the connection between two adjacent side panels, and lower support columns are arranged at the four corners of the bottom of the base, and the upper support columns correspond to the lower support columns.

[0008] The bottom bracket and the side panels are respectively provided with a plurality of evenly distributed ventilation holes.

[0010] An electrical component box is also provided. The side of the outer box is fixedly connected to the electrical component box, and the electrical component box is connected to a control panel.

DETAILED DESCRIPTION

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 、 2As shown in Figure 3, an electromagnetic heating calcination device in this embodiment includes an outer box 2, and a base 1 is symmetrically arranged at the bottom of the outer box 2 for supporting the outer box 2. A horizontally arranged calcination barrel 5 is passed through the outer box 2, and a tray support beam 15 is symmetrically arranged inside the calcination barrel 5. The spacing between the two tray support beams 15 matches the tray, and a tray with medicinal materials is placed between the two tray support beams 15. One end of the calcination barrel 5 is an open end, and the open end is covered with a sealing cover 6, and the other end of the calcination barrel 5 is a closed end. An electromagnetic coil 11 is evenly wrapped around the outer circumference of the calcination barrel 5, and the electromagnetic coil 11 heats the calcination barrel 5, and then calcines the medicinal materials in the tray. A heat dissipation unit is also provided in the outer box 2, and an air outlet 14 is provided at the top of the outer box 2. The heat dissipation unit dissipates heat from the calcination barrel, and the hot air flows out through the air outlet 14.

[0019] A heat-insulating layer 10 is provided between the calcined medicine cylinder 5 and the electromagnetic coil 11 . The heat-insulating layer 10 is wrapped around the outer periphery of the calcined medicine cylinder 5 to keep the calcined medicine cylinder 5 warm.

[0020] The top of the calcining barrel 5 is connected to a one-way pressure relief valve 7, a vent valve 8, and a temperature sensor 9. The air inside the barrel 5 expands due to heat and is discharged through the one-way pressure relief valve 7, preventing the dangerous pressure buildup inside the barrel. Opening the vent valve 8 allows air to flow into the barrel, balancing the pressure inside and outside the barrel.

[0021] The heat dissipation unit includes fins 12, which are located at the closed end of the calcined medicine barrel 5. A heat dissipation cavity is formed between the closed end of the calcined medicine barrel 5 and the closed end of the outer box. A fan 13 is located at the bottom of the heat dissipation cavity and below the fins. To dissipate heat, fan 13 is turned on to cool the calcined medicine barrel, and the heat-exchanged air flows out through the air outlet.

[0022] like Figure 4 As shown, the pallets each include a rectangular base 16 surrounded by side panels 17. Upper support columns 19 are provided at the junctions of adjacent side panels 17. Lower support columns 20 are provided at the four corners of the bottom of the base 16, with the upper support columns 19 corresponding to the lower support columns 20. Multiple pallets can be stacked, with the lower support columns of the upper pallet supported on the upper support columns of the lower pallet.

[0023] A plurality of evenly distributed ventilation holes 18 are provided on the bottom bracket 16 and the side panels 17 to facilitate air circulation of the tray.

[0024] The side of the outer box 2 is fixedly connected to the electrical component box 3, and the electrical component box 3 is connected to the control panel 4.

[0025] Usage process:

[0026] 1. The medicinal materials are loaded into pallets. After multiple pallets are stacked, they are lifted by a forklift and placed on the pallet support beam inside the calcining barrel.

[0027] 2. Close the sealing cover and turn on the heating power supply through the control panel. The electromagnetic coil heats the calcining cylinder, and the temperature of the inner cavity of the calcining cylinder gradually rises. The temperature sensor measures the temperature of the inner cavity of the calcining cylinder and displays it on the control panel. When the temperature of the inner cavity of the calcining cylinder reaches the set temperature, the heating stops. After a period of time, when the temperature of the inner cavity of the calcining cylinder falls below the set temperature, the electromagnetic coil is energized again for heating. This cycle continues until the calcination is completed.

[0028] 3. After calcination is completed, turn off the heating power supply and turn on the fan to cool the calcined medicine cylinder. When the temperature inside the calcined medicine cylinder is below 70℃, open the vent valve through the control panel to let air in. After the air pressure inside and outside the calcined medicine cylinder stabilizes, open the sealing cover, use a forklift to remove the tray, take out the prepared medicine pieces, and let them cool.

[0029] During the calcination of the present invention, the calcination barrel is sealed, which prevents the burning and ash formation of the medicinal materials. After the calcination is completed, the fan is turned on, and the heat dissipation cavity is inhaled with external air to form an airflow. The heat in the calcination barrel is carried away by the airflow through the heat sink and discharged from the air outlet, which accelerates the temperature reduction in the calcination barrel. After the temperature of the calcination barrel drops, a negative pressure is formed inside. The vent valve is opened to let in air, so that the air pressure inside and outside the calcination barrel is stable. The sealing cover can be opened to take out the tray. The medicinal materials are placed in the tray, and the stacking thickness is relatively thin. They are not in direct contact with the inner wall of the calcination barrel. The trays are stacked by upper and lower support columns, and there is a gap between the two adjacent trays, so that the medicinal materials in the tray can fully contact the hot air flow in the calcination barrel in all directions, ensuring a uniform degree of carbonization. There is no need for stirring to prevent the medicinal materials from breaking.

[0030] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
