Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to an intermittently operating dryer with adjustable hot air circulation up and down. Background Technique

[0002] Dryers are mainly used for drying foods such as nuts, coffee, cocoa, candies, preserved fruits, grains, etc. At present, for existing dryers, the direction of hot air is fixed for intermittent drying. Since the materials on the turning plate are stationary and the material layer in the dryer is relatively thick, more materials with moisture to be dried are required. For example, for materials with a material layer thickness of 1-2 m, since the hot air direction is fixed and blows in from one direction, either downward or upward, the conversion of up and down air cannot be carried out according to the drying characteristics of the materials. Therefore, problems such as low drying effect and slow efficiency will be caused to the materials, which cannot meet the needs of customers. For this reason, we propose an intermittently operating dryer with adjustable hot air circulation up and down. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an intermittently operating dryer with adjustable hot air circulation up and down. When in use, the materials are sent to the turning plate through the feeding port. When the upper wind deflector is on the right side and the lower wind deflector is on the left side, the blowing component is started to work. Since the lower part of the circulating fan blade of the blowing component is blocked, the wind will move upward. Thus, the hot air heated by the heater enters the main box through the first circulation air port to dry the materials on the upper layer of the turning plate. The used hot air is discharged through the second circulation air port to facilitate the heater to heat and use again, so as to dry the materials on the upper layer of the turning plate in a cycle to improve the drying effect on the materials. However, when the materials are piled up thickly, the drying efficiency of the lower-layer materials is relatively slow. At this time, the air cylinder is used to drive the connecting bracket to move, and the movement of the connecting bracket drives the lower wind deflector to move. Thus, under the action of the third rotating shaft, the adjusting plate is rotated. By adjusting the angle of the adjusting plate, the upper wind deflector is driven to move. When the upper wind deflector is on the left side and the lower wind deflector is on the right side, the upper part of the circulating fan blade of the blowing component is blocked, and thus, contrary to the above principle, the materials on the lower layer of the turning plate can be dried in a cycle to further improve the drying effect and efficiency on the materials. When the drying of the materials is completed, the operating handle is rotated to drive the second rotating shaft to rotate, so as to turn over the turning plate, and the dried materials are discharged through the discharging port and the regulating valve. During this process, the moisture exhaust component extracts the humid gas in the main box and discharges it to the outside to further improve the drying efficiency, and the problems in the background technique can be effectively solved.

[0004] To achieve the above object, the utility model provides the following technical solution: An intermittently operating dryer with adjustable hot air circulation up and down, comprising a main box, a blowing component and a moisture exhaust component;

[0005] Two second legs are installed on the lower surface of the main box body. A feed inlet is provided on the upper surface of the main box body.

A regulating valve is installed at the discharge outlet. A moisture exhaust component is installed on the right side of the main box body. A secondary box body is installed on the left side of the main box body. A first leg is installed on the lower surface of the secondary box body. A second rotating shaft is rotatably installed inside the main box body. A flap is installed on the second rotating shaft. First ventilation holes are evenly provided on the flap. An operation handle is installed on the right side of the main box body. The operation handle is connected to the second rotating shaft. A first circulation air inlet and a second circulation air inlet are respectively provided in the upper and lower parts on the left side inside the main box body;

[0006] A blowing component is installed on the left side of the secondary box body. A heater is installed on the top of the secondary box body. The outlet of the heater is communicated with the secondary box body. A first slide rail and a second slide rail are sequentially installed inside the secondary box body from top to bottom. Both the first slide rail and the second slide rail are located between the first circulation air inlet and the second circulation air inlet. A third rotating shaft is installed on the right side in the middle of the secondary box body. An adjusting plate is installed on the third rotating shaft. An upper wind baffle and a lower wind baffle are respectively rotatably installed at the upper and lower ends of the adjusting plate. The upper wind baffle is slidably connected to the first slide rail. The lower wind baffle is slidably connected to the second slide rail. Second ventilation holes are evenly provided on the adjusting plate. A cylinder is installed on the left side of the secondary box body. The right end of the piston rod of the cylinder is installed with a connecting bracket. The upper end of the connecting bracket is connected to the lower wind baffle.

[0007] Further, the blowing component includes a support frame installed on the left side of the secondary box body. A first motor bracket is installed on the support frame. A first motor is installed on the first motor bracket. The output shaft of the first motor is connected to a transmission shaft through a coupling. A first pulley is installed on the transmission shaft. A first rotating shaft is also rotatably installed on the left side of the secondary box body. A second pulley is installed at the left end of the first rotating shaft. The first pulley and the second pulley are connected by belt drive. A circulating air blade is installed at the right end of the first rotating shaft. The circulating air blade is located between the first slide rail and the second slide rail and on the left side inside the secondary box body. The input end of the first motor is electrically connected to the output end of an external controller. By controlling the first motor to work through the external controller, the first motor drives the transmission shaft and the first pulley to rotate. The rotation of the first pulley drives the second pulley to rotate under the action of the belt. The rotation of the second pulley drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the circulating air blade to rotate, so as to blow air into the secondary box body.

[0008] Further, the moisture exhaust assembly includes a moisture exhaust pipe, an upper moisture exhaust port, a lower moisture exhaust port, and a second motor bracket. The upper moisture exhaust port and the lower moisture exhaust port are respectively opened at the upper and lower parts on the right side of the main box body. The moisture exhaust pipe is respectively communicated with the upper moisture exhaust port and the lower moisture exhaust port. A moisture exhaust fan is installed on the second motor bracket. The moisture exhaust fan is connected to the moisture exhaust pipe. The input end of the moisture exhaust fan is electrically connected to the output end of an external controller. By controlling the operation of the moisture exhaust fan through the external controller, the moisture exhaust fan operates to extract the humid gas in the main box body through the moisture exhaust pipe, the upper moisture exhaust port, and the lower moisture exhaust port and discharge it to the outside, improving the drying efficiency. When in use, when the hot air in the main box body blows upward, the upper moisture exhaust port is opened and the lower moisture exhaust port is closed. When the hot air in the main box body blows downward, the lower moisture exhaust port is opened and the upper moisture exhaust port is closed.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this up-and-down adjustable hot air circulation intermittent dryer, when in use, the material is sent to the turning plate through the feeding port. When the upper wind deflector is on the right side and the lower wind deflector is on the left side, the blowing assembly is started to operate. Since the lower part of the circulating air blade of the blowing assembly is blocked, the wind will move upward. As a result, the hot air heated by the heater enters the main box body from the first circulation air port to dry the material on the upper layer of the turning plate. The used hot air is discharged through the second circulation air port to facilitate the heater to heat it again for use, and thus the material on the upper layer of the turning plate is dried by circulation to improve the drying effect on the material. However, when the material is stacked thickly, the drying efficiency of the lower-layer material is slow. At this time, the connecting bracket is driven to move by using the air cylinder. The movement of the connecting bracket drives the lower wind deflector to move, and thus the adjusting plate is rotated under the action of the third rotating shaft. By adjusting the angle of the adjusting plate, the upper wind deflector is driven to move. When the upper wind deflector is on the left side and the lower wind deflector is on the right side, the upper part of the circulating air blade of the blowing assembly is blocked, and thus, contrary to the above principle, the material on the lower layer of the turning plate can be dried by circulation to further improve the drying effect and efficiency on the material. When the drying of the material is completed, the second rotating shaft is rotated by turning the operating handle to turn over the turning plate, and the dried material is discharged through the discharging port and the regulating valve. During this process, the moisture exhaust assembly extracts the humid gas in the main box body and discharges it to the outside to further improve the drying efficiency.

Detailed implementation manners

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figure 1 , this embodiment provides a technical solution: a hot air circulation intermittent dryer that can be adjusted up and down, including a main box body 1, a blowing assembly and a moisture exhaust assembly;

[0014] Two second legs are installed on the lower surface of the main box body 1. A feeding port is opened on the upper surface of the main box body 1. A cover plate 19 is detachably installed at the feeding port. A discharging port is opened at the lower end of the conical part of the main box body 1. A regulating valve 26 is installed at the discharging port. A moisture exhaust assembly is installed on the right side of the main box body 1. An auxiliary box body 13 is installed on the left side of the main box body 1. A first leg 12 is installed on the lower surface of the auxiliary box body 13. A second rotating shaft is rotatably installed inside the main box body 1. A flap 20 is installed on the second rotating shaft. First ventilation holes are evenly opened on the flap 20. An operation handle is installed on the right side of the main box body 1. The operation handle is connected to the second rotating shaft. First circulation air vents 16 and second circulation air vents 27 are respectively opened in the upper and lower parts on the left side inside the main box body 1;

[0015] A blowing component is installed on the left side of the auxiliary box body 13, and a heater 2 is installed on the top of the auxiliary box body 13. The outlet of the heater 2 is communicated with the auxiliary box body 13. A first slide rail 15 and a second slide rail 18 are sequentially installed in the auxiliary box body 13 from top to bottom. Both the first slide rail 15 and the second slide rail 18 are located between the first circulation air outlet 16 and the second circulation air outlet 27. A third rotating shaft is installed on the right side in the middle of the auxiliary box body 13, and an adjusting plate 17 is installed on the third rotating shaft. Upper windshields 9 and lower windshields 11 are respectively rotatably installed at the upper and lower ends of the adjusting plate 17. The upper windshields 9 are slidably connected with the first slide rail 15, and the lower windshields 11 are slidably connected with the second slide rail 18. Second ventilation holes are evenly formed in the adjusting plate 17. A cylinder 10 is installed on the left side of the auxiliary box body 13. A connecting bracket 14 is installed at the right end of the piston rod of the cylinder 10. The upper end of the connecting bracket 14 is connected with the lower windshield 11.

[0016] During use, the material is sent to the turning plate 20 through the feeding port. When the upper windshields 9 are located on the right side and the lower windshields 11 are located on the left side, the blowing component is started to work. Since the lower part of the circulating air blades of the blowing component is blocked, the wind will move upward. As a result, the hot air heated by the heater 2 enters the main box body 1 from the first circulation air outlet 16 to dry the material on the upper layer of the turning plate 20 by lifting. The used hot air is discharged through the second circulation air outlet 27 to facilitate the heater 2 to heat and use again, so as to dry the material on the upper layer of the turning plate 20 in a cycle to improve the drying effect of the material by lifting. However, when the material accumulates thickly, the drying efficiency of the lower layer of the material is slow. At this time, the cylinder 10 is used to drive the connecting bracket 14 to move. The movement of the connecting bracket 14 drives the lower windshield 11 to move, thereby rotating the adjusting plate 17 under the action of the third rotating shaft. By adjusting the angle of the adjusting plate 17, the upper windshields 9 are driven to move. When the upper windshields 9 are located on the left side and the lower windshields 11 are located on the right side, the upper part of the circulating air blades of the blowing component is blocked, so that, contrary to the above principle, the material on the lower layer of the turning plate 20 can be dried by lifting in a cycle to further improve the drying effect and efficiency of the material by lifting. When the drying of the material is completed, the second rotating shaft is rotated by turning the operating handle to turn over the turning plate 20, and the dried material is discharged through the discharging port and the regulating valve 26. During this process, the moisture exhaust component extracts the humid gas in the main box body 1 and discharges it to the outside to further improve the drying efficiency by lifting.

[0017] The blowing component includes a support frame 4 installed on the left side of the secondary box body 13. A first motor bracket is installed on the support frame 4, and a first motor 3 is installed on the first motor bracket. The output shaft of the first motor 3 is connected to a transmission shaft through a coupling. A first pulley 5 is installed on the transmission shaft. A first rotating shaft 8 is also rotatably installed on the left side of the secondary box body 13. A second pulley 7 is installed at the left end of the first rotating shaft 8. The first pulley 5 and the second pulley 7 are connected by a belt 6 in a transmission fit. A circulating air blade is installed at the right end of the first rotating shaft 8. The circulating air blade is located between the first slide rail 15 and the second slide rail 18 and on the left side inside the secondary box body 13. The input end of the first motor 3 is electrically connected to the output end of an external controller. By controlling the operation of the first motor 3 through the external controller, the first motor 3 drives the transmission shaft and the first pulley 5 to rotate. The rotation of the first pulley 5 drives the second pulley 7 to rotate under the action of the belt 6. The rotation of the second pulley 7 drives the first rotating shaft 8 to rotate, and the rotation of the first rotating shaft 8 drives the circulating air blade to rotate, thereby blowing air into the secondary box body 13.

[0018] The moisture exhaust component includes a moisture exhaust pipe 22, an upper moisture exhaust port 21, a lower moisture exhaust port 23, and a second motor bracket 25. The upper moisture exhaust port 21 and the lower moisture exhaust port 23 are respectively opened at the upper and lower parts on the right side of the main box body 1. The moisture exhaust pipe 22 is respectively communicated with the upper moisture exhaust port 21 and the lower moisture exhaust port 23. A moisture exhaust fan 24 is installed on the second motor bracket 25. The moisture exhaust fan 24 is connected to the moisture exhaust pipe 22. The input end of the moisture exhaust fan 24 is electrically connected to the output end of an external controller. By controlling the operation of the moisture exhaust fan 24 through the external controller, the moisture exhaust fan 24 operates to extract the humid gas in the main box body 1 through the moisture exhaust pipe 22, the upper moisture exhaust port 21, and the lower moisture exhaust port 23 and discharge it to the outside, improving the drying efficiency. When in use, when the hot air in the main box body 1 blows upward, the upper moisture exhaust port 21 is opened and the lower moisture exhaust port 23 is closed. When the hot air in the main box body 1 blows downward, the lower moisture exhaust port 23 is opened and the upper moisture exhaust port 21 is closed.

[0019] The working principle of a hot - air circulation intermittent dryer that can be adjusted up and down provided by the present utility model is as follows: When in use, the material is sent to the turning plate 20 through the feeding port. When the upper wind baffle 9 is on the right side and the lower wind baffle 11 is on the left side, the blowing assembly is started. Since the lower part of the circulating wind blade of the blowing assembly is blocked, the wind will move upward. As a result, the hot air heated by the heater 2 enters the main box body 1 from the first circulation air port 16 to dry the material on the upper layer of the turning plate 20 by lifting. The used hot air is discharged through the second circulation air port 27 to facilitate the heater 2 to heat it again for use, and thus the material on the upper layer of the turning plate 20 is dried by lifting in a cycle to improve the drying effect of lifting the material. However, when the material accumulates thickly, the drying efficiency of the lower - layer material is slower. At this time, the air cylinder 10 is used to drive the connecting bracket 14 to move. The movement of the connecting bracket 14 drives the lower wind baffle 11 to move, and thus the adjusting plate 17 is rotated under the action of the third rotating shaft. By adjusting the angle of the adjusting plate 17, the upper wind baffle 9 is driven to move. When the upper wind baffle 9 is on the left side and the lower wind baffle 11 is on the right side, the upper part of the circulating wind blade of the blowing assembly is blocked, and thus, contrary to the above principle, the material on the lower layer of the turning plate 20 can be dried by lifting in a cycle to further improve the drying effect and efficiency of the material. When the drying of the material is completed, the operating handle is rotated to drive the second rotating shaft to rotate, so as to turn over the turning plate 20, and the dried material is discharged through the discharging port and the regulating valve 26. In this process, the moisture - discharging assembly extracts the moist gas in the main box body 1 and discharges it to the outside to further improve the drying efficiency. The external controller controls the first motor 3 to work. The first motor 3 drives the transmission shaft and the first pulley 5 to rotate. The rotation of the first pulley 5 drives the second pulley 7 to rotate under the action of the belt 6. The rotation of the second pulley 7 drives the first rotating shaft 8 to rotate, and the rotation of the first rotating shaft 8 drives the circulating wind blade to rotate, so as to blow air into the auxiliary box body 13. The external controller controls the moisture - exhausting fan 24 to work. The moisture - exhausting fan 24 uses the moisture - exhausting pipe 22, the upper moisture - exhausting port 21 and the lower moisture - exhausting port 23 to extract the moist gas in the main box body 1 and discharge it to the outside to improve the drying efficiency. When in use, when the hot air in the main box body 1 blows upward, the upper moisture - exhausting port 21 is opened and the lower moisture - exhausting port 23 is closed. When the hot air in the main box body 1 blows downward, the lower moisture - exhausting port 23 is opened and the upper moisture - exhausting port 21 is closed.

[0020] It should be noted that in this embodiment, the core chip of the external controller is an STC single - chip microcomputer, and the specific model is STC15W204S. The air cylinder 10, the first motor 3 and the moisture - exhausting fan 24 can be freely configured according to the actual application scenario. The external controller controls the air cylinder 10, the first motor 3 and the moisture - exhausting fan 24 to work by using the commonly used methods in the existing technology.
