DETAILED DESCRIPTION

[0032] like Figure 1-9 A device for facilitating the circulation drying of walnuts is provided, comprising a drying bin 2 arranged on a fixed frame 1, a turning cage 6 rotatably provided in the drying bin 2, an inlet hopper 3 and an outlet hopper 4 provided on the upper and lower sides of the drying bin 2 respectively, a hot air pipe 7 inserted on one side of the drying bin 2, and the hot air pipe 7 is used to provide a drying heat source for the interior of the drying bin 2.

[0033] The fixing frame 1 is adjusted to a suitable position, the walnuts are fed through the feeding hopper 3, and then the drying bin 2 is temporarily closed. The hot air pipe 7 passes hot air into the drying bin 2. The hot air and the walnuts transfer heat while taking away moisture to achieve the purpose of drying. The turning cage 6 turns and displaces the walnuts in the drying bin 2 to ensure that the walnuts circulate and roll in the drying bin 2 as evenly as possible, and the area in contact with the hot air is larger and more sufficient, thereby improving the drying efficiency. When the drying is completed, the discharging hopper 4 is opened, and the turning cage 6 is continued to be rotated to discharge the walnuts in the drying bin 2. The overall operation is convenient and the use effect is good.

[0034] In a preferred embodiment, a feed port 203 and a discharge port 204 are provided at the top and bottom of the drying chamber 2 respectively, and the feed hopper 3 and the discharge hopper 4 are connected to the feed port 203 and the discharge port 204 respectively via screws 11 .

Since the walnuts become more brittle after drying, the integrity of the walnuts from drying to bagging is ensured. At the same time, the overall installation and disassembly is convenient and easy to maintain.

[0036] In the preferred embodiment, the drying chamber 2 includes a first semi-ring plate 201 and a second semi-ring plate 202 arranged opposite to each other, the first semi-ring plate 201 and the second semi-ring plate 202 are connected by screws 11, the feed port 203 and the discharge port 204 are respectively arranged on the first semi-ring plate 201 and the second semi-ring plate 202, and a sealing plate 211 is provided at the ends of the first semi-ring plate 201 and the second semi-ring plate 202.

[0037] The drying chamber 2 adopts a detachable structure, which is easy to manufacture and install, and more convenient for later maintenance. The sealing plate 211 is fixed at both ends of the first half ring plate 201 and the second half ring plate 202 by welding, and the structure is stable and the load-bearing sealing is better.

[0038] In the preferred solution, the outer side of the sealing plate 211 is detachably provided with an anti-rotation support 8, and the outer sides of the first half-ring plate 201 and the second half-ring plate 202 are provided with ear plates 212.

[0045] The support frame 501 is also provided with ribs to ensure that the motor 502 is positioned accurately and works stably. The hot air pipe 7 is externally connected to a hot air blower to continuously pass hot air into the drying chamber 2.

[0046] In the preferred solution, limiting sleeves 12 are respectively provided on both sides of the top of the fixing frame 1, the shaft rod 606 and the hot air pipe 7 are respectively inserted into the limiting sleeves 12, a wire mesh 703 is provided at the end of the hot air pipe 7, and a reference sleeve 701 is provided in the middle of the hot air pipe 7. The reference sleeve 701 is against the outside of the limiting sleeve 12, and a buffer cylinder 702 is provided on one side of the reference sleeve 701, and a one-way valve is provided in the buffer cylinder 702.

[0047] Bearings are provided in the limit sleeve 12 to improve the overall load-bearing capacity and ensure smooth rotation.

The control box can control the ventilation time of the hot air blower and the temperature of the hot air. With the cooperation of the one-way valve, it plays a role in energy saving and environmental protection.

[0048] In the preferred embodiment, the fixing frame 1 is further provided with a first switch door 9 and a second switch door 10, and the first switch door 9 and the second switch door 10 are respectively provided with a first plug plate 905 and a second plug plate 1005, and the first plug plate 905 and the second plug plate 1005 are respectively connected to the feed port 203 and the discharge port 204.

[0049] The state of the drying chamber 2 is changed by the state of the first plug plate 905 and the second plug plate 1005. The operation is convenient and the use effect is good. Rubber buffer pads are provided at the ends of the first plug plate 905 and the second plug plate 1005.

[0050] In a preferred embodiment, the first switch door 9 includes a first bracket 901 and a first locking sleeve 902. A first cylinder 903 is sleeved in the first locking sleeve 902. A first push rod 904 is slidably mounted in the first cylinder 903. A first insert plate 905 is fixed to the end of the first push rod 904.

[0051] The second switch door 10 includes a second bracket 1001 and a second locking sleeve 1002. The second locking sleeve 1002 is provided with a second cylinder 1003. A second push rod 1004 is slidably provided in the second cylinder 1003. A second plug plate 1005 is fixed to the end of the second push rod 1004. A first through groove 205 and a second through groove 206 are respectively provided on one side of the feed port 203 and the discharge port 204. The first plug plate 905 is plugged into the first through groove 205, and the second plug plate 1005 is plugged into the second through groove 206.

[0052] The first bracket 901 and the second bracket 1001 are respectively installed on the fixing frame 1 by screws 11, which are easy to manufacture and have strong bearing capacity, ensuring the high installation accuracy of the first cylinder 903 and the second cylinder 1003. The limit stroke of the first push rod 904 is greater than the internal width of the feed port 203 and smaller than the external width of the feed port 203. The limit stroke of the second push rod 1004 is greater than the internal width of the discharge port 204 and smaller than the external width of the discharge port 204. That is, the first plug plate 905 and the second plug plate 1005 are at the farthest position when the drying chamber 2 is closed, and at the closest position when the drying chamber 2 is opened. When in the closest position, the ends of the first plug plate 905 and the second plug plate 1005 are respectively located in the first through groove 205 and the second through groove 206, thereby preventing the first plug plate 905 and the second plug plate 1005 from being separated from the drying chamber 2, and the overall use is safe and stable.
