Technical Field

[0001] This utility model belongs to the technical field of drying mechanisms, and particularly relates to a drying mechanism for a magnesium coating production line. Background Technology

[0002] The main purpose of coating silicon steel with magnesium oxide is to form an insulating layer on the surface of silicon steel sheets and improve the performance of silicon steel sheets. After the silicon steel is coated with magnesium oxide, it needs to be dried by drying equipment. The solvent in the coating is removed by heating, ventilation and other methods to make the magnesium oxide coating dry initially and form a solid magnesium oxide film.

[0003] Existing drying mechanisms use heating elements installed inside them for heating. During use, areas closer to the heating elements absorb more heat preferentially, while areas farther away absorb less heat, resulting in temperature differences. This causes uneven heating of the silicon steel coating, affecting the drying effect and quality of the coating.

[0004] Therefore, it is necessary to improve the drying mechanism of the existing magnesium coating production line. Utility Model Content

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the drying mechanism and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] like Figure 1 and 3 As shown, a drying mechanism for a magnesium coating production line includes two hollow heating plates 2 facing each other, with a drying channel between the two heating plates 2 for the roll material to pass through; a heater 3 is detachably installed inside the heating plate 2; flexible hoses 202 connecting the two heating plates 2 are provided on both sides of the drying channel, and a circulation pump 203 is installed on the flexible hoses 202; an adjusting mechanism is also provided on the two heating plates 2, which is used to adjust the distance between the two heating plates 2.

[0020] The aforementioned drying mechanism is applicable, but not limited to, drying silicon steel coils coated with magnesium oxide. During operation, the heating plate 2 is filled with a liquid heat-conducting medium, which can be molten salt. Molten salt has advantages such as high thermal conductivity, rapid heat transfer, high temperature stability, low vapor pressure, and low volatility. It also exhibits good chemical stability and low corrosiveness to equipment, meeting the requirements for coating drying. After the heat-conducting medium is heated to the required temperature by the heater 3, a circulating pump 203 provides power to circulate the medium between the two heating plates 2. This circulation ensures uniform contact between the heat-conducting medium and the heater 3, resulting in a uniform temperature. Since the heating plate 2 is completely filled with heat-conducting medium, the heat is evenly diffused through the heating plate 2 to the coil, achieving uniform heating and improving the drying effect and quality of the coating. The adjustable distance mechanism can adjust the distance between the heating plate 2 and the coil to ensure effective heat transfer and further improve the drying effect of the coating.

[0021] Compared with existing drying mechanisms that directly heat through heating wires, the above-mentioned heating mechanism can evenly deliver heat to all parts of the heating plate 2 through a flowing heat-conducting medium, making the heat of the heating plate 2 uniform and improving the drying effect on the coating; and the heat-conducting medium has the function of storing heat, so even if the temperature of the heater 3 fluctuates slightly, the temperature of the heating plate 2 can be kept stable by the heat stored in the heat-conducting medium, ensuring the drying effect on the coating.

[0022] Further improvements include, for example Figure 5 and 6 As shown, the heating plate 2 has an insertion interface 207 that is sealed and plugged into the heater 3. The heater 3 can extend into the interior of the heating plate 2 through the insertion interface 207. A sealing ring can be provided at the tail of the heater 3 to achieve a seal between the heater 3 and the insertion interface 207. This facilitates the disassembly and assembly of the heater 3 and improves the ease of maintenance of the heater 3.

[0023] Further improvements include, for example Figure 2 and 3 As shown, the adjusting mechanism includes a cylindrical enclosure 1. A heating plate 2 is slidably disposed inside the enclosure 1 along a direction perpendicular to its own plane. The enclosure 1 is fixedly connected to a power component that is drively connected to the heating plate 2. A guide post 102 is fixedly connected to the inner side of the enclosure 1, perpendicular to the plane of the heating plate 2. A sliding sleeve 204 is fixedly connected to the heating plate 2, fitted onto the guide post 102 and sliding along it. The power component is a cylinder 101, with two cylinders fixed to the enclosure 1 and connected to two heating plates 2 respectively. The sliding sleeve 204 and guide post 102 provide support and guidance for the heating plate 2, improving its stability. The cylinders 101 provide power for the sliding of the heating plate 2, allowing for individual adjustment of the positions of the two heating plates 2, thereby adjusting the distance between the heating plates 2 and the distance between the heating plate 2 and the roll material.

[0024] Further improvements include, for example Figure 5 As shown, both sides of the two heating plates 2 facing away from each other are covered with an insulation layer 201. The insulation layer 201 can be made of ceramic fiber blanket. Ceramic fiber has low thermal conductivity, low heat capacity, excellent chemical stability and thermal stability, and can maintain good insulation performance at high temperatures. It is also lightweight, flexible, and easy to install. By setting the insulation layer 201, the heat loss of the heating plate 2 on the side facing away from the roll material can be reduced, the insulation performance of the drying mechanism can be improved, and its energy consumption can be reduced.

[0025] Further improvements include, for example Figure 4 As shown, sealing strips 205 are provided on the opposite sides of the two heating plates 2, and the sealing strips 205 are distributed on both sides of the drying channel along the extension direction of the drying channel. The drying channel is composed of two heating plates 2 and sealing strips 205. The sealing strips 205 on the two heating plates 2 are staggered. When the distance between the two heating plates 2 is adjusted, the sealing strips 205 on the two heating plates 2 are in an abutting state, thereby achieving a sealing effect. The setting of sealing strips 205 can reduce the heat loss between the two heating plates 2 from both sides of the drying channel, thereby improving the energy-saving performance and drying effect of the equipment.

[0026] Further improvements include, for example Figure 1 As shown, the heating plate 2 is vertically positioned, causing the drying channel to extend vertically downwards. The roll material moves vertically downwards within the drying channel, ensuring that the coating on both sides of the roll material experiences uniform gravity, thus maintaining coating uniformity. Furthermore, the heat generated during the drying process rises along the drying channel, allowing the rising heat to preheat the roll material entering the drying channel later, achieving an energy-saving effect.

[0027] Further improvements include, for example Figure 5 As shown, an extension plate 4 is provided on the top of the heating plate 2, and the side of the extension plate 4 adjacent to the drying channel overlaps with the side of the heating plate 2 adjacent to the drying channel. The extension plate 4 extends the drying channel upward, forming a preheating channel above the heating plate 2. The waste heat generated in the heating chamber enters the preheating channel upward and preheats the roll material within the preheating channel, which can improve the preheating effect and enhance the energy-saving effect of the drying mechanism.

[0028] Further improvements include, for example Figure 2 As shown, an exhaust gas box 5 is provided on the outside of the enclosure 1. The exhaust gas box 5 is provided with an exhaust port 501. An air extraction component is provided between the exhaust gas box 5 and the extension plate 4. The air extraction component is connected to the drying channel. Since harmful gases and water vapor are generated during the coating drying process, the extraction component includes an extraction pipe 401 connecting the preheating channel and the exhaust gas box 5. An air pump 402 is installed on the extraction pipe 401, and a filter element is installed inside the exhaust gas box 5. Due to the high temperature of the exhaust gas generated during drying, it will move upward and enter the preheating channel. The exhaust gas inside the preheating channel is sent into the exhaust gas box 5 through the extraction pipe 401, which can reduce the emission of harmful gases and improve the energy-saving effect of the equipment. In addition, the exhaust gas can exchange heat inside the exhaust gas box 5, which raises the internal temperature of the exhaust gas box 5. The exhaust gas box 5 is set on the enclosure 1. The exhaust gas box 5, which has a certain temperature, surrounds the heating plate 2, which can play a role in heat preservation of the heating plate 2 and improve the energy-saving effect. The extraction pipe 401 is connected to the top of the extension plate 4. By extracting air, a certain vacuum can be created at the top of the preheating channel, which will cause the generated exhaust gas to move upward, thereby reducing the amount of exhaust gas diffused from the bottom of the drying channel and improving the environmental protection effect of the equipment.

[0029] Further improvements include, for example Figure 6 As shown, a perforated plate 208 is provided inside the heating plate 2 along the drying channel. When the heat transfer medium circulates inside the heating plate 2, it can be evenly diffused inside the heating plate 2 through the perforated plate 208, further improving the uniformity of heat distribution throughout the heating plate 2 and enhancing the drying effect on the coating on the roll material.
