Description

Technical Field

[0001] This application relates to the field of grain drying technology, for example, to a drying apparatus. Background Technology

[0002] A related technology (publication number: CN208688215U) discloses a dual-circulation rice drying tower, including a first drying tower, a first elevator, a second elevator, a first drying chamber, and an air inlet. The first drying tower has a first grain inlet at its top and a first grain outlet at its bottom. The top of the first elevator is connected to the first grain inlet via a discharge pipe. The second drying tower is arranged parallel to the first drying tower, with a second grain inlet at its top and a third grain outlet at its bottom. The top of the second elevator is connected to the second grain inlet via a discharge pipe, and the second elevator lifts the rice dried in the first drying tower into the second drying tower. The first drying chamber is located on the first layer of the second drying tower, with a fourth grain outlet at its bottom. A stirring device is installed inside the first drying chamber. The stirring device is a hollow cavity with multiple stirring rods of varying lengths, each with evenly distributed air outlets. An air inlet is located on the upper surface of the stirring device and is connected to a heat pump. The air inlets are spaced apart on the side walls of the first drying chamber and the second drying chamber. The air inlets are sealed with branch hot air pipes, which are sealed to the air outlet of the heat pump through the main hot air pipe.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] In this dual-circulation rice drying tower, hot air generated by a heat pump is transported through a main hot air duct and multiple branch hot air ducts, and then discharged into the first and second drying towers through multiple air inlets. Simultaneously, it is discharged into the first and second drying towers through air inlets and outlets to dry the rice that falls into them. However, rice can easily enter the branch hot air ducts, main hot air ducts, and stirring rods through the multiple air inlets and outlets, which can easily cause blockages and rice waste.

[0017] The drying apparatus provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a drying apparatus comprising multiple drying towers, multiple elevators, multiple hot air ducts, multiple drying pipes, multiple blowers, and a hot air furnace. Each drying tower includes an inlet and an outlet, with the inlets and outlets respectively used to receive and discharge materials. The outlet of one drying tower is used to discharge the dried material. Each elevator includes a loading port and a unloading port, with the unloading ports facing the inlets and used to feed materials into them. The loading port of one elevator receives the material to be dried initially, while the loading ports of the other elevators are connected to the outlets of the remaining drying towers to receive the dried material. Multiple hot air ducts are installed on the outer walls of the drying towers and are used to contain hot air. Multiple drying pipes are evenly distributed throughout the drying towers and are used to heat and dry the materials within them. Each drying pipe on any drying tower is connected to its corresponding hot air duct and is used to transfer heat. Each blower includes an intake port and an exhaust port, with multiple intake and exhaust ports used for drawing in and discharging hot air, respectively.

[0019] During operation, controlling the hot air furnace generates hot air. Then, controlling multiple blowers delivers the hot air to multiple hot air ducts, which in turn flow into multiple drying pipes connected to these ducts. Because these drying pipes are evenly distributed across multiple drying ovens, heat is evenly distributed throughout the ovens after heat transfer, effectively heating and drying materials falling inside. Furthermore, since the drying pipes are installed through the side walls of the ovens but not connected to the interior, materials are discharged directly from the multiple outlets without entering the drying pipes. This avoids blockages and waste.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides a drying apparatus, including multiple drying towers 10, multiple elevators 20, multiple hot air ducts 30, multiple drying pipes 40, multiple blowers 50, and a hot air furnace 60. Each drying tower 10 includes a feed inlet and a discharge outlet, with the multiple feed inlets and discharge outlets respectively used to receive and discharge materials. The discharge outlet of one drying tower 10 is used to discharge the dried material. Each elevator 20 includes a loading inlet and a unloading inlet, with the multiple unloading inlets facing the multiple feed inlets respectively, used to feed materials into the multiple feed inlets. The loading inlet of one elevator 20 is used to receive the material to be dried initially, and the loading inlets of the other multiple elevators 20 are respectively connected to the discharge outlets of the other multiple drying towers 10, used to receive the dried material. Multiple hot air ducts 30 are respectively installed on the outer walls of the multiple drying towers 10, used to contain hot air. Multiple drying pipes 40 are evenly distributed through the multiple drying towers 10, used to heat and dry the materials inside the multiple drying towers 10. Multiple drying pipes 40 on any drying tower 10 are connected to hot air ducts 30 thereon for heat transfer. Each blower 50 includes an exhaust port and an exhaust port, with the exhaust ports for drawing in and discharging hot air, respectively. Multiple exhaust ports are connected to multiple drying pipes 40 to deliver hot air to them. A hot air furnace 60 is connected to multiple exhaust ports to generate hot air.

[0037] This embodiment of the drying apparatus provides a method for controlling a hot air furnace 60 to generate hot air. Then, multiple blowers 50 are controlled to deliver the hot air into multiple hot air ducts 30, which in turn enter multiple drying pipes 40 connected to the hot air ducts 30. Since the multiple drying pipes 40 are evenly distributed within the multiple drying furnaces, heat is evenly distributed within the furnaces after heat transfer, thereby heating and drying the materials falling into the furnaces. Furthermore, because the multiple drying pipes 40 are installed through the side walls of the furnaces but not connected to the interior, the material is discharged directly from the multiple discharge ports without entering the drying pipes 40. This avoids blockages and waste.

[0038] Optionally, combined Figures 1 to 3 As shown, it also includes a fan assembly 70. The fan assembly 70 is installed in each hot air duct 30 and is used to deliver hot air into the multiple drying ducts 40.

[0039] In this embodiment of the disclosure, a fan assembly 70 is used to increase the speed at which hot air enters the multiple drying pipes 40 from each hot air duct 30, thereby improving the heating effect and accelerating drying.

[0040] Optionally, combined Figures 1 to 3 As shown, each fan assembly 70 includes multiple rotating shafts 71 and multiple fan blades 72. The multiple rotating shafts 71 are rotatably mounted on the sidewall of the hot air duct 30 along the length of the drying tower 10, and are distributed sequentially from bottom to top along the height of the drying tower 10 on the sidewall of the hot air duct 30. Each rotating shaft 71 can rotate relative to the hot air duct 30. The multiple fan blades 72 are respectively mounted on the multiple rotating shafts 71 and are all located inside the hot air duct 30, rotating under the drive of the multiple rotating shafts 71. The multiple rotating shafts 71 can be controlled to rotate, thereby driving the multiple fan blades 72 to rotate.

[0041] In this embodiment of the present disclosure, when the multiple rotating shafts 71 rotate under the drive of an external force, the multiple fan blades 72 can also rotate. Since the multiple rotating shafts 71 are distributed from bottom to top on the sidewall of the hot air duct 30, the multiple fan blades 72 are distributed from bottom to top inside the hot air duct 30, so that the hot air in each hot air duct 30 can be evenly entered into the multiple drying pipes 40 to ensure the temperature uniformity inside the drying tower 10.

[0042] Optionally, combined Figures 1 to 3 As shown, each fan assembly 70 further includes multiple first pulleys 73 and a first belt 74. The multiple first pulleys 73 are respectively mounted on multiple rotating shafts 71, each driving the shafts 71 to rotate. Along the height of the drying tower 10, the diameter of the multiple first pulleys 73 decreases sequentially from bottom to top. The first belts 74 are respectively mounted between two adjacent first pulleys 73, each transmitting driving force. Any one rotating shaft 71 can be controlled to rotate, causing the other rotating shafts 71 to rotate simultaneously.

[0043] In this embodiment, when any rotating shaft 71 rotates under the drive of an external force, it drives the first pulley 73 on it to rotate. Then, driven by multiple belts, the others rotate, thereby driving the remaining rotating shafts 71 to rotate simultaneously. A single power source can achieve the function of multiple rotating shafts 71 rotating simultaneously. Since hot air enters from the lower part of the hot air duct 30, it is easier to enter the multiple lower drying pipes 40. The design of the diameter of the multiple first pulleys 73 decreasing from bottom to top allows the rotational speed of the multiple fans to increase sequentially from top to bottom, thereby increasing the amount of hot air entering the multiple upper drying pipes 40, improving the uniformity of hot air in the multiple drying pipes 40, and further improving the temperature uniformity within the drying tower 10.

[0044] Optionally, combined Figures 1 to 3 As shown, each fan assembly 70 further includes a support rod 75, a motor mounting plate 76, a drive motor 77, a second pulley 78, and a second belt 79. The support rod 75 is mounted on the outer wall of the hot air duct 30 to support the motor mounting plate 76. The motor mounting plate 76 is mounted on the support rod 75 to support the drive motor 77. The drive motor 77 is mounted on the motor mounting plate 76, and the axis of its rotating end is parallel to the axes of the plurality of rotating shafts 71 to provide driving force. The second pulley 78 is mounted on the rotating end of the drive motor 77 and rotates under the drive of the drive motor 77. The second belt 79 is installed between the second pulley 78 and any of the first pulleys 73 to transmit driving force.

[0045] In this embodiment, controlling the motor to operate will drive the second pulley 78 to rotate. The second belt 79 will drive the first pulley 73 connected to it to rotate, and then multiple first belts 74 will drive the remaining second pulleys 78 to rotate simultaneously, ultimately realizing the function of simultaneous rotation of multiple rotating shafts 71.

[0046] Optionally, combined Figures 1 to 3 As shown, each fan assembly 70 also includes a bearing housing and a bearing. The bearing housing is mounted in the hot air duct 30 and is respectively fitted onto multiple rotating shafts 71. The bearings are respectively installed between the multiple bearing housings and the multiple rotating shafts 71.

[0047] In this embodiment of the disclosure, multiple bearing seats are used to support and install multiple bearings, and multiple bearings are used to support and install multiple rotatable shafts 71, thereby reducing the frictional force on the multiple shafts 71 and improving the rotational accuracy of the multiple shafts 71.

[0048] Optionally, combined Figures 1 to 3 As shown, each fan assembly 70 also includes a sealing cover. The sealing cover is installed at the end of each bearing housing and abuts against multiple bearings.

[0049] In this embodiment of the disclosure, multiple sealing caps are used to provide sealing protection and to axially limit the movement of multiple bearings.

[0050] Optionally, combined Figure 1 As shown, it also includes a first air supply duct 80. The first air supply duct 80 is installed between multiple exhaust outlets and multiple drying ducts 40.

[0051] In this embodiment of the disclosure, a plurality of first air ducts 80 are used to transport hot air so that the hot air enters from a plurality of blowers 50 into a plurality of hot air ducts 30.

[0052] Optionally, combined Figure 1As shown, it also includes a second air supply duct 90. The second air supply duct 90 is installed between multiple air exhaust ports and the hot air furnace 60.

[0053] In this embodiment of the disclosure, a plurality of second air ducts 90 are used to transport hot air so that the hot air enters from the hot air furnace 60 into a plurality of blowers 50.
