Description

Technical Field

[0001] This utility model belongs to the technical field of drying devices, and specifically relates to a drying device. Background Technology

[0002] After harvest, cereal crops typically contain a high moisture content, making them susceptible to damage from mold, bacteria, and insects. Drying reduces their moisture content, significantly extending their shelf life and preventing spoilage. Therefore, drying equipment is necessary for drying cereals.

[0003] Most existing drying devices work by feeding materials into the drying tank through the inlet, then drying the grains through a drying mechanism on the outside, and finally stirring the grains by rotating the stirring column. While this method can dry the grains, it mostly heats and dries the grains from the outside, not from the center. Heat needs to be gradually transferred to the core of the material, making the entire drying process more time-consuming and reducing drying efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a drying device. By setting up a drying cylinder and supplying hot air into the drying cylinder, it can not only heat the grains from the outside but also ensure that the heat can penetrate to the center of the material pile, achieving more uniform heating and drying, thereby shortening the time required for the entire drying process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a drying device, including a drying tank, an electric heating device is provided inside the side wall of the drying tank, a top cover is provided on the top of the drying tank, a drying cylinder is provided inside the drying tank, a plurality of air blowing holes smaller than bean particles are provided on the side end of the drying cylinder, an installation cylinder is rotatably provided on the upper end of the drying cylinder via a bearing, the installation cylinder is located at the lower end of the top cover, a drive unit for rotating the installation cylinder is provided on the top cover, a scraping assembly is provided at the lower end of the installation cylinder, the scraping assembly includes a fixing plate provided on the installation cylinder, a scraper first is provided at the end of the fixing plate away from the installation cylinder, the scraper first abuts against the inner side wall of the drying tank, and a scraper second is provided on the lower side of the end of the fixing plate near the installation cylinder, the scraper second abuts against the outer side wall of the drying cylinder.

[0006] As a further improvement of this utility model, the drive unit includes a mounting box 1 disposed at the lower end of the cover plate. A rotating column is rotatably disposed on the upper side wall of the mounting box 1. A gear 1 is disposed at the lower end of the rotating column. A gear 2 that meshes with the gear 1 is fixedly disposed on the outer arc surface of the mounting cylinder. A drive component for driving the rotating column to rotate is disposed at the upper end of the cover plate. The drive component includes a motor disposed at the left end of the mounting box 2. A worm gear is rotatably disposed inside the right end of the mounting box 2. A worm wheel that meshes with the worm gear is disposed at the upper end of the rotating column extending into the interior of the mounting box 2.

[0007] As a further improvement of this utility model, a dryer connected to the drying cylinder is provided at the upper end of the drying tank.

[0008] As a further improvement of this utility model, a feed inlet is provided at the rear end of the drying tank, and an exhaust pipe is provided at the upper end of the top cover.

[0009] As a further improvement of this utility model, a discharge pipe is provided at the lower end of the drying tank, and a discharge valve is provided at the discharge pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by setting up a dryer, hot air can be delivered into the drying drum, thereby drying the middle part of the grain material through the drying drum. By directly delivering hot air into the drying drum, not only can the grain be heated from the outside, but it can also ensure that the heat can penetrate into the center of the material pile, achieving more uniform heating and drying. This helps to avoid the problem of the surface being too dry while the inside is still moist, thus improving the overall drying efficiency.

[0012] Secondly, by setting up installation box one and installation box two, the drive unit can be protected to prevent grain materials from affecting the drive components and improve equipment safety.

[0013] Thirdly, by setting scraper one and scraper two, the residual material on the inner wall of the drying tank and the outer wall of the drying cylinder can be scraped off. The material adhering to the wall of the drying tank or drying cylinder will form a heat insulation layer, which will hinder the heat transfer. By removing these materials in time by scraper, a more direct and efficient heat exchange between the hot air or heating surface and the material can be ensured.

[0014] Fourth, by setting up a discharge pipe with a discharge valve, the flow rate can be adjusted according to the material characteristics by adjusting the valve opening, thus avoiding pipe blockage caused by excessive flow rate. Attached Figure Description

Detailed Implementation

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 , 2 As shown in Figure 3, a drying device includes a drying tank 101. An electric heating device is installed inside the side wall of the drying tank 101. A top cover 102 is installed on the top of the drying tank 101. A drying cylinder 103 is installed inside the drying tank 101. Multiple air holes 104, smaller than bean particles, are provided on the side end of the drying cylinder 103. An mounting cylinder 105 is rotatably mounted on the upper end of the drying cylinder 103 via a bearing. The mounting cylinder 105 is located below the top cover 102. The top cover 102 is equipped with... A drive unit is provided for rotating the mounting cylinder 105. A scraping assembly is provided at the lower end of the mounting cylinder 105. The scraping assembly includes a fixing plate 201 provided on the mounting cylinder 105. A scraper 202 is provided at the end of the fixing plate 201 away from the mounting cylinder 105. The scraper 202 abuts against the inner wall of the drying tank 101. A scraper 203 is provided on the lower side of the end of the fixing plate 201 near the mounting cylinder 105. The scraper 203 abuts against the outer wall of the drying cylinder 103.

[0023] like Figure 2 , 3As shown, the drive unit includes a mounting box 204 located at the lower end of the cover plate. A rotating column 205 is rotatably mounted on the upper side wall of the mounting box 204. A gear 206 is mounted at the lower end of the rotating column 205. A gear 207 meshing with the gear 206 is fixedly mounted on the outer arc surface of the mounting cylinder 105. A drive component for driving the rotating column 205 to rotate is located at the upper end of the cover plate. The drive component includes a motor 208 located at the left end of the mounting box 211. A worm gear 209 is rotatably mounted inside the right end of the mounting box 211. A worm wheel 210 meshing with the worm gear 209 is located at the upper end of the rotating column 205 extending into the interior of the mounting box 211. When the motor 208 is started, the motor 208 drives the worm gear... When worm gear 209 rotates, it drives worm wheel 210 to rotate, which in turn drives rotating column 205 to rotate. Rotating column 205 drives gear one 206 to rotate, which in turn drives gear two 207 to rotate. Gear two 207 drives mounting cylinder 105 to rotate, thereby driving scraper one 202 and scraper two 203 to rotate via fixing plate 201. This scrapes away residual material on the inner wall of drying tank 101 and the outer wall of drying cylinder 103. Material adhering to the wall of drying tank 101 or drying cylinder 103 forms a heat insulation layer, hindering heat transfer. Timely removal of this material by scrapers ensures a more direct and efficient heat exchange between hot air or heating surface and the material.

[0024] like Figure 1 , 4 As shown, a dryer 301 connected to a drying cylinder 103 is provided at the upper end of the drying tank 101. The dryer 301 can deliver hot air into the drying cylinder 103, thereby drying the middle part of the grain material through the drying cylinder 103. By directly delivering hot air into the drying cylinder 103, not only can the grain be heated from the outside, but it can also ensure that the heat can penetrate to the center of the material pile, achieving more uniform heating and drying. This helps to avoid the problem of the surface being too dry while the inside is still moist, thus improving the overall drying efficiency.

[0025] like Figure 1 As shown, the rear end of the drying tank 101 is provided with a feed inlet 302.

[0026] like Figure 1 , 4 As shown, a discharge pipe 304 is provided at the lower end of the drying tank 101, and a discharge valve 305 is provided at the discharge pipe 304. By adjusting the opening of the valve, the flow rate can be adjusted according to the material characteristics to avoid the problem of pipe blockage caused by excessive flow rate.

[0027] In operation, the grain material to be dried is conveyed into the drying tank 101 through the feed inlet 302. The electric heating device is activated to heat the feed inside the drying tank 101. Then, the dryer 301 is activated, which can supply hot air into the drying cylinder 103. This allows the grain material to be dried in the center through the drying cylinder 103. By directly supplying hot air into the drying cylinder 103, not only can the grain be heated from the outside, but the heat can also be ensured to penetrate to the center of the material pile, achieving more uniform heating and drying. Next, the motor 208 is activated, which drives the worm gear 209 to rotate. The worm gear 209 drives the worm wheel 210 to rotate, which in turn drives the rotating column 205 to rotate. The rotating column 205 drives the gear... When wheel 1 206 rotates, gear 1 206 drives gear 2 207 to rotate, which in turn drives the mounting cylinder 105 to rotate. This, in turn, drives scraper 1 202 and scraper 2 203 to rotate via the fixing plate 201, thereby scraping off the residual material on the inner wall of the drying tank 101 and the outer wall of the drying cylinder 103. The material adhering to the wall of the drying tank 101 or the drying cylinder 103 forms a heat insulation layer, which hinders heat transfer. Timely removal of this material by the scrapers ensures a more direct and efficient heat exchange between the hot air or heating surface and the material. After drying, the discharge valve 305 is opened, and the valve opening is adjusted to adjust the flow rate of the discharge port according to the material characteristics, avoiding pipe blockage caused by excessive flow rate.

[0028] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, an exhaust pipe 303 is provided at the upper end of the top cover 102. A large amount of water vapor and other volatile substances (such as natural volatiles in some grains) generated during the drying process need to be discharged in time to maintain a low humidity environment inside the tank and ensure that the material can be effectively dried.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
