Description

Technical Field

[0001] The invention relates to an on-site control cabinet, and in particular to an on-site control cabinet for gates regulated based on water level changes. Background Art

[0002] The local control cabinet is a device used for on-site control, usually installed near the equipment, and used to directly control and monitor the operating status of the equipment. The local control cabinet is equipped with a programmable controller and various sensors and other front-end devices to automatically control the gate opening and closing equipment to achieve water level changes.

[0003] Since the gate on-site control cabinet is set near the water area, the surrounding air humidity is relatively high due to the temperature difference between day and night. When the moisture entering the control cabinet reaches a certain content, it will damage the electrical components and affect the gate's regulation of the water level. At present, dehumidification is mainly achieved by hanging desiccant in the control cabinet or installing a dehumidification structure in the control cabinet to prevent damage to the electrical components. For example, the patent with prior art announcement number CN113507052A discloses an outdoor open-air electrical control cabinet with a dehumidification function. The air intake fan is driven by the operation of a first motor to rotate, so that air enters the interior of the box through the air inlet. When the air passes through the drying box, the desiccant in the drying box dries the internal air entering the box to prevent humid air from entering the interior of the box. The dry air enters the interior of the box, which can cause the air inside the box to flow, so that the humid air is discharged through the exhaust port.

[0004] However, the existing technology still has the following defects: due to the temperature difference between day and night in the water environment, the on-site control cabinet of the gate will face a high humidity environment for a long time, and the water absorption performance of the desiccant is constant. When the water absorption degree of the desiccant reaches saturation, it can no longer absorb moisture, resulting in the desiccant being difficult to perform long-term dehumidification protection for the control cabinet that is in a humid environment for a long time. Summary of the invention

[0005] In view of the problem in the prior art that in the face of a long-term high humidity environment, the desiccant's water absorption efficiency will lose its function of drying moisture after reaching saturation, a gate on-site control cabinet based on water level change regulation is proposed.

[0006] The purpose is to make the desiccant circulate and come into contact with the hot air discharged from the control cabinet to dissipate the adsorbed moisture and achieve long-term dehumidification.

[0007] The technical solution of the present invention is a gate on-site control cabinet based on water level change regulation, including a control cabinet body, and also including a shell installed on the top of the control cabinet body, the shell is a concave structure, a fixing plate is horizontally connected to the shell, the fixing plate cooperates with the upper part of the shell and the inner concave part of the shell to form a T-shaped exhaust cavity, the fixing plate cooperates with the lower part of the shell to form a convex air inlet cavity, a bidirectional fan blade is provided in the middle of the air inlet cavity, dehumidification components are installed in both sides of the air inlet cavity, a lifting mechanism is installed in the inner concave part of the shell, a motor is fixedly installed in the middle of the upper side of the exhaust cavity, and the motor is transmission-connected with the bidirectional fan blade and the lifting mechanism;

[0008] The dehumidification assembly includes a plurality of baffles connected and fixed to the air inlet cavity, the baffles cooperate with the air inlet cavity to form an S-shaped air duct, and a plurality of rollable drying balls are evenly distributed in the S-shaped air duct;

[0009] The lifting mechanism includes a fixed cylinder fixedly connected to the middle part of the inner recess of the shell, and two through holes are provided at the upper and lower ends of the fixed cylinder for the passage of drying balls. The upper through hole is connected to the upper part of the air inlet chamber with a conveying trough 1, and the lower through hole is connected to the lower part of the air inlet chamber with a conveying trough 2. The conveying troughs 1 and 2 are both inclined, and an auger is rotatably provided in the fixed cylinder, and the auger is driven by a motor. The auger cooperates with the fixed cylinder to convey the drying balls on the conveying trough 2 to the conveying trough 1.

[0010] By adopting the above technical scheme, when the motor drives the two-way fan blades to rotate, the outside air enters the control cabinet body through the air inlet chamber, the internal air pressure of the control cabinet body increases, and the hot air on the top is discharged to the outside of the shell through the exhaust chamber. After the outside air enters the air inlet chamber, it flows in the S-shaped air duct and contacts with the drying ball. The drying ball absorbs moisture in the air and reduces the humidity content of the air. The drying ball that has absorbed the moisture rolls along the conveying groove two to the fixed cylinder. During the rolling process of the drying ball in the conveying groove two, the hot air inside the control cabinet body contacts the drying ball and takes away most of the moisture. The motor drives the auger to rotate, and transports the drying ball to the upper end of the fixed cylinder, and returns to the S-shaped air duct again through the conveying groove one, so that the drying ball can circulate and self-dry, thereby achieving a continuous air dehumidification effect.

[0011] Furthermore, both ends of the bottom of the shell are fixedly connected with air ducts, and the air ducts extend to the bottom of the control cabinet body.

[0012] By adopting the above technical solution, the air duct transports the dehumidified outside air to the bottom of the control cabinet body. Utilizing the principle that hot air rises, the cold air automatically gathers upward after absorbing the heat of the electrical components in the control cabinet body, and is discharged to the outside through the exhaust cavity, achieving a rapid air exchange effect.

[0013] Furthermore, the top surface of the baffle is provided with an inclined surface, the inclined surface is provided with an S-shaped rolling groove, the drying balls roll on the S-shaped rolling groove, and both sides of the S-shaped rolling groove are staggered and evenly provided with adjustment protrusions, and the adjustment protrusions are hook-shaped structures.

[0014] By adopting the above technical solution, the S-shaped rolling groove has multiple bends, so that it has a sufficiently long stroke, and the flowing outside air contacts the rolling drying ball to achieve dehumidification of the outside air. At the same time, each time the drying ball contacts an adjusting protrusion, the rolling axis position of the drying ball can be changed, so that all surfaces of the drying ball can contact the outside air, thereby maximizing the dehumidification effect of the drying ball.

[0015] Furthermore, one end of the conveying groove one is connected to the upper S-shaped rolling groove, and one end of the conveying groove two is connected to the lower S-shaped rolling groove, and a guide plate is connected between the two vertical S-shaped rolling grooves.

[0016] By adopting the above technical solution, the end of the conveying trough one close to the fixed cylinder is higher than the end connected to the S-shaped rolling groove, so that the drying balls discharged through the upper through hole can move along the conveying trough one into the S-shaped rolling groove. The setting of the guide plate can prevent the drying balls from deviating during the falling process, so that they can accurately fall into the lower S-shaped rolling groove.

[0017] Furthermore, the bidirectional fan blades are composed of two fan blades with opposite wind directions, and the bidirectional fan blades are fixedly connected to the rotating shaft at the output end of the motor.

[0018] By adopting the above technical solution, when the motor drives the bidirectional fan blades to rotate clockwise (looking down), the outer fan blades drive the air to flow downward, so that the outside air enters the control cabinet body through the S-shaped air duct, and the inner fan blades drive the hot air in the control cabinet body to be discharged to the outside through the exhaust cavity, so that the control cabinet body and the outside world form a directional, slow and uniform air flow path.

[0019] Furthermore, an S-shaped ventilation hole is opened on the second conveying groove, and the drying ball is rolled on the S-shaped ventilation hole, and one end of the S-shaped ventilation hole is connected to the lower S-shaped rolling groove, and the other end is connected to the lower through hole.

[0020] By adopting the above technical solution, the hot air in the control cabinet body comes into contact with the drying ball when passing through the S-shaped ventilation hole and being discharged to the outside through the exhaust cavity. Most of the moisture absorbed by the drying ball itself is taken away by the flowing hot air, so that the moisture content of the drying ball is lower than the humidity content in the outside air, so that the drying ball can continue to absorb moisture after drying and returning to the S-shaped air duct.

[0021] Furthermore, the auger is slidably connected to the rotating shaft, the top of the auger is symmetrically structured and rotatably connected to two guide wheels, an annular guide groove is provided on the upper part of the fixed cylinder, the guide wheel is in rolling contact with the annular guide groove, and the annular guide groove is formed by four evenly distributed U-shaped grooves.

[0022] By adopting the above technical scheme, the auger is composed of an inclined auger blade and a circular plate connected to its two ends. The left side of the U-shaped groove is vertically arranged, and the right side is inclined. When the rotating shaft drives the auger to rotate clockwise, the guide wheel contacts the inclined part on the right side of the U-shaped groove and drives the auger to rise in the fixed cylinder. When the guide wheel is located on the left side of the U-shaped groove, the auger falls and resets under the action of gravity, so that the auger performs intermittent up and down movement during the rotation process. When the auger is located on the lower side, the drying ball enters the fixed cylinder through the lower through hole, and then the auger rises, so that the distance between the lower end of the auger and the through hole is reduced, thereby preventing the drying ball from detaching from the through hole when the auger rotates.

[0023] Furthermore, a limit assembly is provided on the lower side of the fixed cylinder, and the limit assembly includes a cross bar rotatably connected to the auger, and the end of the cross bar vertically slides with the shell, and support frames are fixedly connected on both sides of the cross bar, and multiple limit rods are vertically evenly distributed on the support frame, and the limit rods are arranged on the S-shaped ventilation hole.

[0024] By adopting the above technical solution, the distance between two adjacent limit rods is greater than the diameter of the drying ball. The limit rod rises and falls synchronously with the auger. After the limit rod rises, it is located on the S-shaped ventilation hole to block the rolling of the drying ball. The limit rod falls below the S-shaped ventilation hole to make the drying ball roll on the inclined surface of the second conveying trough. As a result, multiple drying balls are spread out at equal intervals, which is conducive to taking away moisture from the drying balls when hot air flows. At the same time, the drying balls can be intermittently moved into the fixed cylinder to avoid movement interference such as blockage.

[0025] Furthermore, two dehumidification units are symmetrically provided on the top of the exhaust cavity, and the dehumidification unit includes a water collecting trough, and a plurality of trapezoidal plates are evenly distributed on the upper side of the water collecting trough, and the water collecting trough and the trapezoidal plates are both connected and fixed to the shell.

[0026] By adopting the above technical solution, the hot air drives the absorbed moisture to flow to the outside and contacts the trapezoidal plate. Part of the moisture can adhere to the trapezoidal plate and condense into water droplets. The water droplets drip onto the water collecting tank along the lower inclined surface of the trapezoidal plate. The water collecting tank is connected to the outside of the shell through a drain pipe to discharge the water vapor, so that the humidity of the discharged air is lower than the humidity of the outside air. The air that absorbs the water vapor is discharged and mixed with the outside air, thereby further reducing the humidity content of the air entering the control cabinet body.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The dry ball rolls by itself in the S-shaped air duct. The fixed cylinder and the auger cooperate to lift the dry ball at a lower position to a higher position, so that the dry ball circulates in the air inlet chamber and the exhaust chamber. The dry ball absorbs moisture from the outside air in the air inlet chamber, and then contacts with the hot air in the exhaust chamber to dissipate the moisture. The dry ball is self-drying during the circulation process, so that the outside air can be dehumidified continuously to ensure the safety of the electrical components in the control cabinet body.

[0029] 2. When the drying ball rolls in the S-shaped rolling groove, it contacts the adjusting protrusion, which can change the rolling axis of the drying ball, so that all surfaces of the drying ball are in contact with the outside air, thereby maximizing the moisture absorption effect. At the same time, the intermittent lifting of the limit rod can control the intermittent rolling of the drying ball in the second conveying groove, thereby maximizing the moisture removal effect of the drying ball, thereby further improving the moisture removal effect of the drying ball in the outside air and the continuous drying time.

[0030] 3. When the exhausted hot air drives the moisture through the trapezoidal plate, part of the moisture can adhere to the trapezoidal plate and condense into water droplets and drip onto the water collection tank. The water collection tank discharges the water vapor, making the exhaust air humidity lower than the outside air humidity. The air that absorbs the water vapor is discharged and mixed with the outside air, thereby further reducing the air humidity content entering the control cabinet body.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] Example 1, reference Figure 1-Figure 10, which is the first embodiment of the present invention, provides a gate on-site control cabinet based on water level change regulation, including a control cabinet body 1, and also includes a shell 2 installed on the top of the control cabinet body 1, the shell 2 is a concave structure, and a fixing plate 201 is horizontally connected to the shell 2, the fixing plate 201 cooperates with the upper part of the shell 2 and the inner concave part of the shell 2 to form a T-shaped exhaust cavity, the fixing plate 201 cooperates with the lower part of the shell 2 to form a convex air inlet cavity, a bidirectional fan blade 3 is arranged in the middle of the air inlet cavity, dehumidification components 4 are installed in both sides of the air inlet cavity, a lifting mechanism 5 is installed in the inner concave part of the shell 2, a motor 6 is fixedly installed in the middle of the upper side of the exhaust cavity, and the motor 6 is transmission-connected to the bidirectional fan blade 3 and the lifting mechanism 5; the dehumidification component 4 includes a plurality of baffles 401 connected and fixed to the air inlet cavity The baffle 401 cooperates with the air inlet chamber to form an S-shaped air duct, and a plurality of rollable drying balls 403 are evenly distributed in the S-shaped air duct; the lifting mechanism 5 includes a fixed cylinder 501 fixedly connected to the middle of the inner recess of the shell 2, and two through holes 502 for the drying balls 403 to pass through are provided at the upper and lower ends of the fixed cylinder 501, the upper through hole 502 is connected to the upper part of the air inlet chamber with a conveying trough 1 503, and the lower through hole 502 is connected to the lower part of the air inlet chamber with a conveying trough 2 504, the conveying trough 1 503 and the conveying trough 2 504 are both inclinedly arranged, and an auger 505 is rotatably arranged in the fixed cylinder 501, the auger 505 is driven by the motor 6, and the auger 505 cooperates with the fixed cylinder 501 to convey the drying balls 403 on the conveying trough 2 504 to the conveying trough 1 503.

[0047] Specifically, when the motor 6 drives the bidirectional fan blades 3 to rotate, the outside air enters the control cabinet body 1 through the air inlet chamber, the internal air pressure of the control cabinet body 1 increases, and the hot air on the top is discharged to the outside of the shell 2 through the exhaust chamber. After the outside air enters the air inlet chamber, it flows in the S-shaped air duct and contacts the drying ball 403. The drying ball 403 absorbs moisture in the air and reduces the humidity content of the air. The drying ball 403 that has absorbed the moisture rolls along the conveying groove 504 to the fixed cylinder 501. During the rolling process of the drying ball 403 in the conveying groove 504, the hot air inside the control cabinet body 1 contacts the drying ball 403 and takes away most of the moisture. The motor 6 drives the auger 505 to rotate, and transports the drying ball 403 to the upper end of the fixed cylinder 501, and returns to the S-shaped air duct again through the conveying groove 503, so that the drying ball 403 can circulate and self-dry, thereby achieving a continuous air dehumidification effect.

[0048] It is understandable that, referring to Figure 3 A plurality of louver holes are provided on both symmetrical sides of the shell 2, and the louver holes are arranged at an angle to prevent external debris from entering the shell 2. The exhaust cavity and the air inlet cavity are connected to the louver holes, and air can be exchanged between the inside of the shell 2 and the outside through the louver holes.

[0049] Reference Figure 2Both ends of the bottom of the shell 2 are fixedly connected with air ducts 202, and the air ducts 202 extend to the bottom of the control cabinet body 1.

[0050] Specifically, the air duct 202 transports the dehumidified outside air to the bottom of the control cabinet body 1. By utilizing the principle that hot air rises, the cold air automatically gathers upward after absorbing the heat of the electrical components in the control cabinet body 1, and is discharged to the outside through the exhaust cavity, thereby achieving a rapid air exchange effect.

[0051] Reference Figure 4 The top surface of the baffle 401 is provided with an inclined surface, on which an S-shaped rolling groove 402 is opened, and the drying balls 403 are rolled on the S-shaped rolling groove 402, and both sides of the S-shaped rolling groove 402 are staggered and evenly distributed with adjusting protrusions 404, and the adjusting protrusions 404 are hook-shaped structures.

[0052] Specifically, the S-shaped rolling groove 402 has multiple bends, so that it has a sufficiently long stroke, and the flowing outside air contacts the rolling drying ball 403 to achieve dehumidification of the outside air. At the same time, each time the drying ball 403 contacts an adjustment protrusion 404, the rolling axis position of the drying ball 403 can be changed, so that all surfaces of the drying ball 403 can contact the outside air, thereby maximizing the dehumidification effect of the drying ball 403.

[0053] Among them, the drying balls 403 are evenly distributed in the S-shaped rolling groove 402, the conveying groove 504, the auger 505, and the conveying groove 503. The drying balls 403 in the S-shaped air duct are dehumidified and then enter the conveying groove 504 for drying. The dried drying balls 403 return to the S-shaped air duct, so that the drying balls 403 absorb and dehumidify in the circulation process, thereby achieving a long-term dehumidification effect on the control cabinet body 1.

[0054] The distance between two vertically adjacent baffles 401 is smaller than the diameter of the drying balls 403 , thereby preventing the drying balls 403 from escaping from the S-shaped rolling groove 402 .

[0055] Reference Figure 4 and Figure 8 One end of the conveying groove 503 is connected to the upper S-shaped rolling groove 402, and one end of the conveying groove 504 is connected to the lower S-shaped rolling groove 402. A guide plate 405 is connected between the two vertical S-shaped rolling grooves 402.

[0056] Specifically, one end of the conveying groove 503 close to the fixed cylinder 501 is higher than the end connected to the S-shaped rolling groove 402, so that the drying balls 403 discharged through the upper through hole 502 can move along the conveying groove 503 into the S-shaped rolling groove 402. The setting of the guide plate 405 can prevent the drying balls 403 from deviating during the falling process, so that they can accurately fall into the lower S-shaped rolling groove 402.

[0057] Reference Figure 2 and Figure 7 The bidirectional fan blade 3 is composed of two fan blades with opposite wind directions, and the bidirectional fan blade 3 is fixedly connected to the rotating shaft 601 at the output end of the motor 6.

[0058] Specifically, when the motor 6 drives the bidirectional fan blades 3 to rotate clockwise (from a top-down perspective), the outer fan blades drive the air to flow downward, so that the outside air enters the control cabinet body 1 through the S-shaped air duct, and the inner fan blades drive the hot air in the control cabinet body 1 to be discharged to the outside through the exhaust cavity, so that the control cabinet body 1 and the outside form a directional, slow and uniform air flow path.

[0059] Reference Figure 8 An S-shaped ventilation hole 506 is opened on the second conveying groove 504, and the drying ball 403 is rolled on the S-shaped ventilation hole 506, and one end of the S-shaped ventilation hole 506 is connected to the lower S-shaped rolling groove 402, and the other end is connected to the lower through hole 502.

[0060] Specifically, the hot air in the control cabinet body 1 comes into contact with the drying ball 403 when passing through the S-shaped ventilation hole 506 and being discharged to the outside through the exhaust cavity. Most of the moisture absorbed by the drying ball 403 itself is taken away by the flowing hot air, so that the moisture content of the drying ball 403 is lower than the humidity content in the outside air, so that the drying ball 403 can continue to absorb moisture after drying and returning to the S-shaped air duct.

[0061] The second conveying trough 504 is designed to be higher on the left and lower on the right, and lower in the front and higher in the back, so that the drying balls 403 can roll along the inclined surface of the second conveying trough 504 by themselves.

[0062] Example 2, reference Figure 9-10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the auger 505 is slidably connected to the rotating shaft 601, the top of the auger 505 is symmetrically structured and rotatably connected to two guide wheels 507, the upper part of the fixed cylinder 501 is provided with an annular guide groove 508, the guide wheel 507 is in rolling contact with the annular guide groove 508, and the annular guide groove 508 is formed by four evenly distributed U-shaped grooves.

[0063] Specifically, the auger 505 is composed of an inclined auger blade and a circular plate connected to its two ends. The left side of the U-shaped groove is vertically arranged, and the right side is inclined. When the rotating shaft 601 drives the auger 505 to rotate clockwise, the guide wheel 507 contacts the inclined part on the right side of the U-shaped groove and drives the auger 505 to rise in the fixed cylinder 501. When the guide wheel 507 is located on the left side of the U-shaped groove, the auger 505 falls and resets under the action of gravity, so that the auger 505 intermittently moves up and down during the rotation process. When the auger 505 is located on the lower side, the drying ball 403 enters the fixed cylinder 501 through the lower through hole 502, and then the auger 505 rises, so that the distance between the lower end of the auger 505 and the through hole 502 is reduced, thereby preventing the drying ball 403 from detaching from the through hole 502 when the auger 505 rotates.

[0064] The distance between the auger blade and the inner wall of the fixed cylinder 501 is slightly smaller than the diameter of the drying ball 403, so that when the auger 505 rotates, the drying ball 403 is pushed to roll upward by the inclined surface of the auger blade.

[0065] Reference Figure 8 and Fig.11 A limit assembly 7 is provided on the lower side of the fixed cylinder 501, and the limit assembly 7 includes a cross bar 701 rotatably connected to the auger 505, and the end of the cross bar 701 vertically slides with the shell 2. Support frames 702 are fixedly connected on both sides of the cross bar 701, and a plurality of limit rods 703 are vertically evenly distributed on the support frame 702, and the limit rods 703 are arranged on the S-shaped ventilation hole 506.

[0066] Specifically, the distance between two adjacent limiting rods 703 is greater than the diameter of the drying ball 403, and the limiting rod 703 rises and falls synchronously with the auger 505. After the limiting rod 703 rises, it is located on the S-shaped ventilation hole 506 to block the rolling of the drying ball 403. The limiting rod 703 falls below the S-shaped ventilation hole 506, so that the drying ball 403 rolls on the inclined surface of the second conveying trough 504, thereby making multiple drying balls 403 spread out at equal intervals, which is conducive to taking away moisture on the drying balls 403 when hot air flows, and at the same time, the drying balls 403 can be intermittently moved into the fixed cylinder 501 to avoid motion interference such as blockage. The rest of the structure is the same as that of Example 1.

[0067] Example 3, reference Figure 2 and Fig.12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that two dehumidification units 8 are symmetrically arranged on the top of the exhaust chamber, and the dehumidification unit 8 includes a water collecting trough 801, and a plurality of trapezoidal plates 802 are evenly distributed on the upper side of the water collecting trough 801, and the water collecting trough 801 and the trapezoidal plates 802 are both connected and fixed to the shell 2.

[0068] Specifically, when the hot air drives the absorbed moisture to flow to the outside, it comes into contact with the trapezoidal plate 802. Part of the moisture can adhere to the trapezoidal plate 802 and condense into water droplets. The water droplets drip along the lower inclined surface of the trapezoidal plate 802 to the water collecting tank 801. The water collecting tank 801 is connected to the outside of the shell 2 through a drain pipe to discharge the water vapor, so that the humidity of the discharged air is lower than the humidity of the outside air. The air that absorbs the water vapor is discharged and mixed with the outside air, thereby further reducing the humidity content of the air entering the control cabinet body 1.

[0069] It is understandable that a humidity sensor is installed in the air inlet cavity, the humidity sensor, the motor 6 are connected to the control module, the humidity sensor monitors the humidity of the outside air, and when the humidity of the outside air exceeds the humidity threshold set by the control module, the control module controls the motor 6 to rotate. The rest of the structure is the same as that of Example 2.

[0070] In summary, the working principle of the present invention is as follows: the motor 6 drives the two-way fan blades 3 and the auger 505 to rotate through the rotating shaft 601, and the two-way fan blades 3 drive the outside air to flow into the control cabinet body 1 through the S-shaped air duct, and the outside air contacts the drying ball 403 rolling on the S-shaped rolling groove 402, and the drying ball 403 absorbs moisture from the outside air, and the air with reduced humidity enters the control cabinet body 1 through the air guide 202, and at the same time, the hot air in the upper part of the control cabinet body 1 passes through the S-shaped ventilation hole 506 and is discharged to the outside, and the hot air takes away part of the moisture on the drying ball 403, and the guide wheel 507 cooperates with the annular guide groove 508 to make the auger 505 intermittently move up and down while rotating, and the auger 5 05 is located at the lower side, the limiting rod 703 drops below the S-shaped ventilation hole 506, the drying ball 403 rolls on the inclined surface of the conveying groove 504, and the drying ball 403 close to the fixed cylinder 501 enters the fixed cylinder 501 through the lower through hole 502, and the auger 505 rises to reduce the distance between the lower end of the auger 505 and the through hole 502, thereby preventing the drying ball 403 from escaping from the through hole 502 when the auger 505 rotates. At the same time, the limiting rod 703 rises to be located on the S-shaped ventilation hole 506, blocking the rolling of the drying ball 403, making the drying ball 403 roll intermittently, and the auger 505 drives the drying ball 403 to be discharged from the upper through hole 502, and moves back to the S-shaped air duct through the conveying groove 1 503.
