Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1-5This utility model provides a technical solution: a zero-stage air heater structure, including a heater body 110, a first rotating shaft 120 rotatably mounted on the bottom of the inner wall of the heater body 110, a motor 121 fixedly mounted on the bottom of the first rotating shaft 120, a strip-shaped hole provided on the first rotating shaft 120, a plurality of U-shaped stirring racks 122 slidably mounted on the inner wall of the strip-shaped hole, the plurality of stirring racks 122 being fixedly connected by a quadrangular prism 123, a second rotating shaft 124 rotatably mounted on the top of the quadrangular prism 123, and a second rotating shaft 124 slidably mounted on the top of the second rotating shaft 124. A cylinder 125 is fixedly installed at the top of the first rotating shaft 120 and the top of the heating furnace body 110 and extends to the outside. The output end of the cylinder 125 is fixedly connected to the top of the second rotating shaft 124. Heating rods 126 are symmetrically fixedly installed at the top of the inner wall of the heating furnace body 110. A feed pipe 111 and an air inlet pipe 130 are respectively installed at the top and bottom of the heating furnace body 110. An air inlet assembly matching the air inlet pipe 130 is installed at the bottom of the inner wall of the heating furnace body 110.

[0026] In some specific implementations, grooves are provided on both sides of the strip-shaped hole, and the quadrangular prism 123 is slidably connected to the inner wall of the groove. A gap is provided between the quadrangular prism 123 and the inner wall of the strip-shaped hole. By providing the grooves, the quadrangular prism 123 can slide smoothly within the strip-shaped hole, ensuring smooth operation of the stirring device and extending the service life of the equipment. At the same time, the design of the grooves makes the lifting and lowering of the stirring frame 122 more stable, avoiding equipment damage or uneven heating caused by vibration.

[0027] In some specific implementations, multiple stirring racks 122 are equidistantly fixedly mounted on a quadrangular prism 123. Stirring plates 127 are fixedly mounted at both ends of the stirring racks 122, with the tops of the stirring plates 127 being rounded. The equidistant mounting of the stirring racks 122 on the quadrangular prism 123 ensures uniform air distribution within the heating furnace, preventing localized overheating or underheating. The design of the stirring plates 122 further enhances the air mixing effect, ensuring full contact between the air and the heating rod 126, thus improving heating efficiency.

[0028] In some specific implementations, the air intake assembly is a semi-annular first guide box 131, the air intake pipe 130 is connected to the inside of the first guide box 131, the top of the first guide box 131 is provided with multiple air outlets, the inner wall of the air outlets is provided with a dustproof net, and the inner wall of the first guide box 131 is fixedly installed with a baffle plate 132.

[0029] In some specific implementation schemes, a flue pipe 140 is fixedly installed at the top of the heating furnace body 110, and the other end of the flue pipe 140 is connected to the bottom of the heating furnace body 110 and a second guide box is fixedly installed thereon. An exhaust fan 141 is installed on the flue pipe 140. The cooperation between the flue pipe 140 and the exhaust fan 141 can effectively recycle the heat in the flue gas, improve heating efficiency, reduce energy consumption, and meet the requirements of energy conservation and environmental protection.

[0030] In some specific implementations, the first guide box 131 and the second guide box are identical in shape and symmetrically arranged. The symmetrical arrangement of the first guide box 131 and the second guide box ensures uniform airflow distribution within the heating furnace.

[0031] Working principle: Zero-grade air enters through the inlet pipe 130, which connects to the semi-annular first guide box 131. The inner wall of the air outlet at the top of the first guide box 131 is equipped with a dust filter to filter impurities in the air, ensuring that the air entering the heating furnace reaches a high purity level and meets the purification requirements of zero-grade air. The guide plate 132 on the inner wall of the first guide box 131 guides the air, allowing it to enter the heating furnace more evenly and preventing airflow concentration.

[0032] Heating and stirring: The starter motor 121 drives the first rotating shaft 120 to rotate, and the multiple U-shaped stirring racks 122 on the first rotating shaft 120 rotate accordingly. At the same time, the cylinder 125 pushes the second rotating shaft 124, causing the stirring racks 122 to move up and down along the strip-shaped holes on the first rotating shaft 120. During the rotation and lifting process, the stirring plates 127 at both ends of the stirring racks 122 continuously stir the air in the heating furnace, ensuring that the air is in full contact with the heating rods 126 symmetrically installed at the top of the inner wall of the heating furnace body 110, ensuring that the air is heated evenly and avoiding local overheating or underheating.

[0033] Airflow circulation and heat utilization: The exhaust pipe 140 at the top of the heating furnace body 110 is connected to the bottom, and an exhaust fan 141 is installed on the exhaust pipe 140. After the exhaust fan 141 is started, the flue gas generated in the heating furnace is extracted and sent to the second guide box at the bottom of the heating furnace through the exhaust pipe 140. Since the first guide box 131 and the second guide box are the same shape and symmetrically arranged, the second guide box can guide the heat in the flue gas to participate in the heating circulation of the air in the furnace, realize the recycling of heat, improve heating efficiency, and reduce energy consumption.

[0034] Material addition is optional: If necessary, relevant materials can be added to the heating furnace through the feed pipe 111 to carry out specific production or experimental operations in conjunction with the heating and stirring process.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
