Abstract
Description
Technical Field
[0001] This invention relates to the field of grain processing, and more specifically, to an energy-saving grain drying equipment. Background Technology
[0002] Grain drying equipment is a continuous, large-capacity grain drying and processing equipment, mainly used to solve the problems of storing and processing high-moisture grains after harvest. Existing grain drying equipment consists of a feeding mechanism, a screw conveying mechanism, a discharging mechanism, a blower mechanism, and a heater. However, during grain drying, the grain is usually piled up and turned over, and the grain cannot quickly and fully contact the heated air in a short time, resulting in uneven drying and low drying efficiency, which is not conducive to saving energy and costs.
[0003] For example, the Chinese invention patent (application number: 202310358868.8) discloses a "grain drying device," the description of which states that a horizontal drying drum is typically used to dry grain. This involves a motor driving the horizontal drying drum to rotate, causing the grain inside to tumble and dry. However, in this drying method, the grain is usually piled up and turned over, resulting in poor ventilation inside the piled grain. During drying, the grain cannot quickly and fully contact the heated air, leading to a longer drying time, lower drying efficiency, and hindering energy and cost savings. This patent demonstrates the shortcomings of the existing technology.
[0004] Therefore, we have made improvements and proposed an energy-saving grain drying equipment. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0020] As described in the background art, when grain drying equipment is in operation, the grain is usually piled up and turned over, resulting in uneven drying and low drying efficiency.
[0021] To address this technical problem, the present invention provides an energy-saving grain drying device that is applied to grain processing.
[0022] For details, please refer to Figure 1 - Figure 9 As shown, the energy-saving grain drying equipment specifically includes: a base 1, a screw conveyor mechanism 101 mounted on the base 1, a heater 102 mounted on the base 1, a blower 103 mounted on the base 1, a discharge mechanism 104 mounted on the base 1, a mounting base 105 mounted on the base 1, and a synchronous adjustment mechanism 2 mounted on the mounting base 105. In the prior art, the screw conveyor mechanism 101 is used to convey grain, and the screw conveyor mechanism 101 is an existing shaftless screw conveyor. The heater 102 is used to heat the grain, the blower 103 drives hot air to dry the grain, and the discharge mechanism 104 is used to discharge the dried grain. The synchronous adjustment mechanism 2 includes a fixed base 201 mounted on the mounting base 105, a feed trough 202 mounted on the fixed base 201, a fixed disk 203 mounted on the feed trough 202, a through hole 204 on the fixed disk 203, a drive shaft 205 rotatably mounted on the mounting base 105, a drive disk 206 mounted on the drive shaft 205, a sliding seat 207 mounted on the drive disk 206, a through hole 208 on the sliding seat 207, a motor 209 mounted on the mounting base 105, a connecting cylinder 210 threadedly connected to the mounting base 105, an air outlet 211 on the connecting cylinder 210, a discharge cylinder 212 rotatably mounted on the connecting cylinder 210, an air outlet 213 on the discharge cylinder 212, and a filter screen 214 on the discharge cylinder 212.
[0023] The energy-saving grain drying equipment provided by this invention addresses the problem that in existing grain drying equipment, grain is usually piled up and turned over during operation, resulting in uneven drying and low drying efficiency. This application provides a synchronous adjustment mechanism 2 to intermittently feed the grain. By controlling the amount of grain fed at one time, the grain entering the screw conveyor mechanism 101 is always kept in a thin layer and evenly distributed, thereby improving the uniformity of grain drying. By using the synchronous adjustment mechanism 2, the light impurities mixed with grain are screened and uniformly processed, reducing the subsequent manual screening process for light impurities, improving the drying quality of grain, and solving the problem of light impurities affecting the drying quality in the existing technology. By using the synchronous adjustment mechanism 2, the waste heat inside the equipment is used to preheat the undried grain, which shortens the time of the main drying section, reduces the total energy consumption of the equipment, saves operating costs, and solves the problem of low energy utilization caused by the waste of waste heat in the drying system in the existing technology.
[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, an energy-saving grain drying device has a through hole 204 and a through hole 208 that are adapted to each other, a drive disk 206 that is rotatably mounted on a feed trough 202, a drive shaft 205 that is mounted on a motor 209, a drive shaft 205 that is rotatably mounted on a fixed disk 203, and an air outlet 211 and an air outlet 213 that are adapted to each other. In use, undried grain is placed into the feeding trough 202, and the motor 209 is started. The motor 209 drives the drive shaft 205 to rotate, which in turn drives the drive disc 206, the sliding seat 207, and the second through hole 208 to rotate synchronously. When the second through hole 208 rotates and overlaps with the first through hole 204, the grain in the feeding trough 202 is discharged into the screw conveyor mechanism 101 from the point where the first through hole 204 and the second through hole 208 overlap. Where the first through hole 204 and the second through hole 208 do not overlap, the grain cannot enter the screw conveyor mechanism 101. This method achieves intermittent feeding of grain. By controlling the amount of grain fed at one time, the grain entering the screw conveyor mechanism 101 is always kept in a thin, evenly distributed layer. This process improves the uniformity and efficiency of grain drying. Light impurities inside the mounting cylinder are filtered through filter screen 214. The overlap of air outlet 1 211 and air outlet 213 allows communication between the outside environment and the mounting base 105, enabling the exhaust gas from the mounting base 105 and the screw conveyor mechanism 101 to be discharged. The blower 103 and heater 102 work together to generate hot air, which blows away light impurities from the grain, causing them to accumulate inside the connecting cylinder 210. Rotating the connecting cylinder 210 detaches it from the mounting base 105, allowing workers to clean the filter screen 214 and uniformly process the accumulated light impurities. Furthermore, a cross block 215 is provided on the drive shaft 205, and a baffle 216 is slidably provided on the cross block 215. The baffle 216 is slidably provided on the feed chute 202. When the drive shaft 205 rotates, it drives the cross block 215 and the baffle 216 to rotate synchronously. The rotation of the baffle 216 agitates the grain in the feed trough 202, so that the grain can be stably discharged into the screw conveyor mechanism 101 from the overlapping point of the through hole 1 204 and the through hole 208. This avoids the situation where the grain is too wet and clogs the feed trough 202, and improves the stability of intermittent feeding. The baffle 216 can be slidably disassembled. When a single baffle 216 is damaged, it can be directly replaced. Furthermore, the drive disk 206 is provided with a sliding groove 217, a push block 218 is slidably disposed on the sliding groove 217, a spring 219 is disposed on the corresponding surface of the push block 218 and the sliding groove 217, and a semi-circular groove 220 is disposed on the fixed disk 203. Furthermore, a ball bearing 221 is rotatably mounted on the actuating block 218, and the ball bearing 221 is adapted to the semi-circular groove 220; When the drive shaft 205 rotates, it drives the drive disk 206 to rotate synchronously. The actuating block 218 and the ball 221 on the drive disk 206 rotate synchronously. When the ball 221 and the semi-circular groove 220 disengage, the ball 221 and the actuating block 218 slide synchronously along the sliding groove 217. The spring 219 is compressed and deformed by the actuating block 218. When the ball 221 and the semi-circular groove 220 engage, the elasticity of the spring 219 drives the actuating block 218 and the ball 221 to reset. The ball 221 impacts the semi-circular groove 220, causing the fixed disk 203 to vibrate, preventing the grain from getting stuck in the first through hole 204 and the second through hole 208, thus improving the stability of the equipment. Furthermore, the fixed base 201 is provided with a connecting groove 222 and a preheating hole 223, which communicates with the connecting groove 222 and the feeding groove 202. The connection between the connecting groove 222, the preheating hole 223, and the feeding groove 202 allows hot air from the mounting base 105 to enter the feeding groove 202 through the connecting groove 222 and the preheating hole 223. The hot air preheats the uncooked grain in the feeding groove 202. The rotation and stirring of the baffle 216 ensures that the grain in the feeding groove 202 is heated evenly. Preheating the grain shortens the time of the main drying section and improves the overall drying efficiency. The waste heat in the equipment is used to preheat the uncooked grain, reducing the total energy consumption of the equipment and saving operating costs. The vibration generated by the impact of the ball bearing 221 and the semi-circular groove 220 cleans the preheating hole 223 and reduces the possibility of blockage in the preheating hole 223. The grain is fed intermittently by the synchronous adjustment mechanism 2. By controlling the amount of grain fed at one time, the grain entering the screw conveyor 101 is always kept in a thin layer and evenly distributed state, which improves the uniformity of grain drying. The synchronous adjustment mechanism 2 also screens and uniformly processes light impurities mixed in with the grain, reducing the subsequent manual screening process for light impurities and improving the drying quality of the grain. The waste heat in the equipment is used to preheat the undried grain, shortening the time of the main drying section, reducing the total energy consumption of the equipment, and saving operating costs.
[0028] Example 2 further optimizes the energy-saving grain drying equipment provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, an extension 224 is provided inside the connecting cylinder 210; like Figure 4 and Figure 5 As shown, the cross-section of the extension 224 is triangular. The extension 224 acts as a barrier to reduce the backflow of light impurities in the connecting cylinder 210 into the mounting base 105. Furthermore, a guide groove 225 is provided on the drive shaft 205, a sliding seat 207 is slidably disposed on the guide groove 225, a sliding seat 207 is slidably disposed on the drive disk 206, an electric telescopic rod 226 is provided on the drive disk 206, and the end of the electric telescopic rod 226 is disposed on the sliding seat 207. When the undried grain has a low moisture content, the electric telescopic rod 226 is activated, which drives the sliding seat 207 to slide along the guide groove 225. The sliding seat 207 slides and disengages from the drive disc 206. At this time, the sliding seat 207 disengages from the fixed disc 203, thereby eliminating intermittent feeding and improving the practicality of the device. The energy-saving grain drying equipment provided by this invention is used as follows: In use, undried grain is placed into the feeding trough 202, and the motor 209 is started. The motor 209 drives the drive shaft 205 to rotate, which in turn drives the cross block 215 and the baffle 216 to rotate synchronously. The rotation of the baffle 216 agitates the grain in the feeding trough 202. The drive shaft 205 drives the drive disc 206, the sliding seat 207, and the second through hole 208 to rotate synchronously. When the second through hole 208 rotates and overlaps with the first through hole 204, the grain in the feeding trough 202 is discharged from the point where the first through hole 204 and the second through hole 208 overlap into the screw conveyor mechanism 101. This method achieves grain... Intermittent feeding is used, in which the drive shaft 205 drives the drive disk 206 to rotate synchronously, and the actuating block 218 and ball 221 on the drive disk 206 rotate synchronously. When the ball 221 and the semi-circular groove 220 disengage, the ball 221 and the actuating block 218 slide synchronously along the sliding groove 217, and the spring 219 is compressed and deformed by the actuating block 218. When the ball 221 and the semi-circular groove 220 engage, the elasticity of the spring 219 drives the actuating block 218 and the ball 221 to reset. The ball 221 impacts the semi-circular groove 220, causing the fixed disk 203 to vibrate, preventing the grain from getting stuck in the through hole 204 and the through hole. Within the second 208, the connection groove 222, preheating hole 223, and feeding trough 202 allow hot air from the mounting base 105 to enter the feeding trough 202 through the connection groove 222 and preheating hole 223. The hot air preheats the undried grain in the feeding trough 202. The rotating baffle 216 agitates the grain, ensuring even heating. Vibrations generated by the impact of the ball bearings 221 and the semi-circular groove 220 clean the preheating hole 223, reducing clogging. Light impurities in the mounting cylinder are filtered through the filter screen 214, and air is released through the outlet 211 and the outlet... The overlap of the second vent 213 allows the outside to communicate with the inside of the mounting base 105 through the overlap of the first vent 211 and the second vent 213. This allows the exhaust gas in the mounting base 105 and the screw conveyor mechanism 101 to be discharged from the overlap of the first vent 211 and the second vent 213. The blower 103 and the heater 102 work together to generate hot air, which blows away the light impurities in the grain, causing the light impurities to accumulate in the connecting cylinder 210. Rotating the connecting cylinder 210 causes it to detach from the mounting base 105, allowing the staff to clean the filter screen 214 and uniformly process the accumulated light impurities.
