Description

Technical Field

[0001] This utility model relates to the field of grain drying, and in particular to a mobile dryer. Background Technology

[0002] After soybeans are harvested on farms and impurities are removed and dried, they can be bagged and transported for sale. This type of sale is targeted at processing plants and farmers' markets. However, for the 200g-5kg vacuum-packed soybeans sold in supermarkets for consumers, clean, ready-to-use soybeans are required. Therefore, whether these small packages are processed directly from farms or produced in downstream factories, they need to be cleaned and dried. Based on this problem, we designed a mobile dryer. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a mobile dryer, including a transport trolley, a washing tank, and a drying chamber. The transport trolley has a washing tank and a drying chamber arranged side-by-side. The washing tank has a circular upper section and a funnel-shaped lower section. A discharge port is located below the washing tank, and a control valve is installed at the discharge port. A horizontal conveying pipe is connected below the discharge port, and the other end of the horizontal conveying pipe is connected to the lower side of the drying chamber for feeding. The drying chamber has a cylindrical body structure, and a drying conveying screw is installed inside. A first motor is located above the drying chamber, driving the drying conveying screw to rotate. Multiple drying ventilation holes are evenly arranged on the blades of the drying conveying screw, and the diameter of the drying ventilation holes is smaller than the diameter of the material. An air resistance heating tube is connected to one side of the lower part of the drying chamber via a pipe, and the other side of the air resistance heating tube is connected to a fan. Multiple air outlets are located at the top of the drying chamber, and a drying discharge port is located on one side of the upper part of the drying chamber.

[0004] A conveying screw is installed inside the horizontal conveying pipe, and a second motor is installed on the side of the horizontal conveying pipe away from the drying chamber. The second motor drives the conveying screw to rotate.

[0005] A drain outlet is provided on one side below the cleaning tank. The drain outlet is equipped with a valve and a leak-proof screen.

[0006] The bottom of the horizontal conveying pipe is provided with filter holes along its length.

[0007] A duct is installed on the side of the horizontal conveying pipe near the drying chamber. The duct is horizontal and at the same height as the central axis of the horizontal conveying pipe. The angle between the duct and the horizontal conveying pipe on the side of the drying chamber is less than or equal to 75°. The duct is connected to a ventilation fan.

[0008] A support plate is provided above the cleaning tank, and a stirring motor is provided on the support plate. The rotating shaft below the stirring motor extends into the cleaning tank and has a circular array of stirring blades. The stirring blades are in vertical contour with the inner wall of the cleaning tank.

[0009] The beneficial effects of this utility model are as follows:

[0010] This device washes soybeans through a washing tank and stirring blades, then conveys them horizontally through a horizontal conveying pipe while blowing away moisture through water filter holes and air ducts. Finally, the soybeans are dried in a drying chamber, thus achieving the washing and drying process before packaging. Attached Figure Description

[0018] The heating element and fan of this device are existing technologies and are not the innovations of this case, so they will not be described in detail here.

[0019] This utility model discloses a mobile dryer, including a transport trolley 1, a washing tank 2, and a drying chamber 3. The washing tank and the drying chamber are arranged side by side on the transport trolley. The washing tank has a circular trough structure at the top and a funnel shape at the bottom. A discharge port 4 is provided below the washing tank. The discharge port is equipped with a control valve. A horizontal conveying pipe 5 is connected below the discharge port. The other end of the horizontal conveying pipe is connected to the lower side of the drying chamber for feeding. The main body of the drying chamber is a cylindrical chamber structure. A drying conveying screw 6 is provided inside the drying chamber. A first motor 7 is provided above the drying chamber. The first motor drives the drying conveying screw to rotate. Multiple drying vent holes 8 are evenly arranged on the blades of the drying conveying screw. The diameter of the drying vent holes 8 is smaller than the diameter of the material. An air resistance heating tube 9 is connected to the lower side of the drying chamber through a pipe. The other side of the air resistance heating tube is connected to a fan 10. Multiple air outlets 11 are provided at the top of the drying chamber. A drying discharge port 12 is provided on the upper side of the drying chamber 3.

[0020] A conveying screw 13 is installed inside the horizontal conveying pipe, and a second motor 14 is installed on the side of the horizontal conveying pipe away from the drying chamber. The second motor drives the conveying screw to rotate.

[0021] A drain outlet 15 is provided on one side below the cleaning tank. The drain outlet is equipped with a valve and a leak-proof mesh 16.

[0022] The bottom of the horizontal conveying pipe is provided with filter holes 17 along its length.

[0023] A duct 18 is provided on the side of the horizontal conveying pipe near the drying chamber. The duct is horizontal and at the same height as the central axis of the horizontal conveying pipe. The angle between the duct and the horizontal conveying pipe on the side of the drying chamber is less than or equal to 75°. The duct is connected to a ventilator 10.

[0024] A support plate 19 is provided above the cleaning tank, and a stirring motor 20 is provided on the support plate. The rotating shaft below the stirring motor extends into the cleaning tank and has three stirring blades 21 arranged in a circular array. The stirring blades are in vertical contour with the inner wall of the cleaning tank.

[0025] Specific operations

[0026] First, the soybeans are poured into the washing tank 2 and washed by stirring blades 21. After opening the drain outlet 15 and the anti-leakage screen 16 to prevent the soybeans from flowing out, and after the sewage is drained, the discharge outlet 4 is opened to allow the soybeans to flow into the horizontal conveying pipe 5. At this time, the stirring blades 21 continue to rotate to assist in feeding. When the material enters the horizontal conveying pipe 5, the residual liquid flows in through the water filter hole 17. With the help of the inclined air blowing in, the moisture on the surface of the soybeans is blown off and sent into the drying chamber 3. Under the action of the drying conveying screw 6, the soybeans are slowly conveyed upward. During this process, the heated air moves upward through the evenly arranged drying vent holes 8 to dry the soybeans. Finally, the soybeans are sent out from the inclined discharge outlet to complete the washing and drying process.
