Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mortar drying, and in particular to a high-efficiency drying device for producing dry-mix mortar. Background Art
[0002] Dry mortar is an important building material. Drying is a key step in its production process to remove moisture from the mixture to meet the needs of subsequent processing and use, and to ensure the quality and stability of the final product. The drying process usually converts the chemical energy generated by fuel combustion into thermal energy, and heat is exchanged with wet sand in the dryer through flame radiation and high-temperature flue gas to remove moisture. With the continuous development of technology, the structure and performance of the drying device are continuously optimized to adapt to dry mortar production lines of different scales and needs.
[0003] In the prior art, the drying method is usually combustion heating. Although this method can effectively dry the mortar, it also has some disadvantages. Since the distribution and movement state of the material in the drying drum may be uneven, the drying effect may vary. Some materials may be over-dried, while others may be under-dried. Poor drying uniformity will affect the product quality of the dry mortar and increase the difficulty of quality control.
[0004] In summary, how to solve the problem of uneven distribution of materials in the drying drum in the prior art, which affects the quality of dry-mix mortar products, has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an efficient drying device for dry-mix mortar production. Summary of the invention
[0005] In order to solve the above problems, the present invention provides a high-efficiency drying device for the production of dry-mix mortar. Through the continuous change of airflow and the introduction of tumbling components, the mortar can be continuously tumbled and mixed in the drying box, thereby increasing the contact area between the mortar and the airflow, further improving the uniformity of the drying effect, thereby ensuring the dryness and performance of the mortar.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an efficient drying device for dry mortar production, comprising a drying box, with a feeding port and a discharging port on both sides of the drying box respectively, the feeding port is connected to the top of the drying box, a plurality of support rods are fixedly connected to the bottom of the drying box, a tumbling assembly for tumbling materials and a drying assembly for drying materials are provided inside the drying box; a gas transmission assembly for transmitting gas to the inside of the drying box is provided on the side of the outside of the drying box near the feeding port.
[0007] The air delivery component includes a controller, a housing, and a first driving member for providing a bidirectional rotational force. The controller is used to control the operation of the first driving member. The output shaft of the first driving member close to the drying box is coaxially and fixedly connected with a first gear. The first gear meshes with a second gear, and the second gear meshes with a third gear. The output shaft of the first driving member away from the first gear is fixedly connected with a plurality of fan blades. The fan blades, the first driving member, the first gear, the second gear, and the third gear are all located inside the housing. An air inlet is formed on the side wall of the housing close to the fan blades. The housing is fixedly connected to the outer side wall of the drying box close to the feeding port, the first driving member is fixedly connected to the inner bottom wall of the housing, and both the second gear and the third gear are rotationally matched with the inner side wall of the housing.
[0008] A plurality of ventilation grooves are formed along the circumferences of the sides of the second gear and the third gear close to the housing. The ventilation grooves communicate with the sides of the second gear and the third gear away from the housing. Both the drying box and the housing are provided with figure-eight openings communicating with the ventilation grooves. An air outlet is formed at the top of the drying box away from the feeding port.
[0009] The technical principle of the above solution is as follows:
[0010] The first driving member drives the fan blades to rotate. Since the outer side of the fan blades is sleeved with a housing and the housing is provided with an air inlet, when the fan blades rotate, an air flow will be generated to suck the wind outside into the interior of the housing. Since the output shaft at the other end of the first driving member is coaxially and fixedly connected with a first gear, the first gear meshes with a second gear, and the second gear meshes with a third gear, when the first gear rotates, it can drive the meshing second gear to rotate, and the second gear drives the third gear to rotate. Since a plurality of ventilation grooves are formed along the circumferences of the sides of the second gear and the third gear close to the housing, the ventilation grooves communicate with the sides of the second gear and the third gear away from the housing, and both the drying box and the housing are provided with figure-eight openings communicating with the ventilation grooves, when the wind outside is blown into the housing, the wind can be blown into the interior of the drying box through the provided ventilation grooves and figure-eight openings. Through this special design, when the outside air flow is sucked into the interior of the housing, the conveying channel is narrowed through the ventilation grooves, which can increase the flow rate of the air flow to a certain extent, thereby generating an impact force. Moreover, due to the continuous rotation of the second gear and the third gear, the positions where the ventilation grooves communicate with the figure-eight openings change continuously, so that the air flow is transmitted from different positions, thus generating different impact effects. After the air flow is transmitted into the interior of the drying box, it continuously blows the mortar, thereby taking out the moisture. At the same time, through the design of the tumbling component, the mortar can be evenly blown in the drying box. In this process, the drying component will heat the drying box. Through these synergistic effects, the externally transmitted air flow generates a thermal effect, thereby efficiently drying the mortar.
[0011] The following are the beneficial effects of adopting the above solution:
[0012] 1. The present invention generates air flow through the rotation of the fan blades and cleverly utilizes the meshing transmission between gears, not only realizing the introduction of air flow, but also effectively narrowing the air flow transmission channel and increasing the impact force of the air flow through the ventilation slots on the gears and the special figure-eight opening design; this design enables the air flow to have stronger power when entering the drying box, can penetrate and blow the mortar layer more effectively, and accelerate the evaporation of moisture.
[0013] 2. Through the continuous rotation of the second gear and the third gear in the present invention, the position of the ventilation slot in the figure-eight opening changes continuously, which directly leads to the diversification of the inlet angle and direction of the air flow entering the drying box. When the ventilation slot moves along the figure-eight path, it will point to different corners and areas inside the drying box at different time points, thereby guiding the external air flow to penetrate and fill the entire drying space from multiple distinct angles and directions. This multi-directional air flow distribution mode not only broadens the coverage range of the air flow, but also effectively reduces the drying dead corners that may be caused by traditional unidirectional or fixed-angle air flows, ensuring the comprehensiveness and efficiency of the drying process. The superimposed turbulent flow effect generated by the interaction of multi-directional air flows can further improve the drying efficiency. By combining the dynamic air flow path and the turbulent flow effect, the laminar flow state in the air flow can be broken, promoting the faster and more uniform exchange and transfer of moisture, thereby effectively reducing the local non-uniformity and enabling the material to be dried efficiently.
[0014] 3. Through the introduction of the tumbling component in the present invention, the mortar can be continuously tumbled and mixed inside the drying box, further improving the uniformity of the drying effect. At the same time, the heating effect of the drying component on the drying box is combined with the thermal effect of the air flow to form a powerful drying resultant force. This synergistic effect not only accelerates the drying process, but also improves the drying quality, ensuring the dryness and performance of the mortar. This means that not only can the surface of the mortar receive heat from all sides faster and achieve rapid temperature rise, but the moisture inside it can also evaporate more evenly under the action of dynamic turbulent flow, avoiding problems such as local overheating or uneven drying.
[0015] Furthermore, the tumbling component includes a tumbling barrel and a second driving member for providing driving force, and the controller is used to control the operation of the second driving member; the second driving member is fixedly connected to the outer side wall of the drying box away from the outer shell, and the output shaft of the second driving member extends into the drying box and is coaxially and fixedly connected with a connecting rod; the connecting rod is rotationally matched with the drying box, and one end of the connecting rod away from the second driving member is fixedly connected with a plurality of rotating rods; the ends of the rotating rods away from the connecting rod are all fixedly connected to the inner side wall of the tumbling barrel, and openings communicating with the drying box are formed on both sides of the tumbling barrel; the tumbling barrel is rotationally matched with the inner side wall of the drying box, and a plurality of inclined arc-shaped plates are fixedly connected to the inner side wall of the tumbling barrel along its length direction; a plurality of ventilation holes are formed in the side wall in the length direction of the arc-shaped plate, and a sealing net for blocking the inflow of materials is fixedly connected to the outside of each ventilation hole, and the tumbling barrel and the rotating rod have the same rotation center.
[0016] Beneficial effects: The second driving member drives the connecting rod to rotate. Since the connecting rod is rotationally engaged with the drying box, several rotating rods are fixedly connected to the connecting rod, and the rotating rods are all fixedly connected to the inner side wall of the tumbling barrel. The tumbling barrel is rotationally engaged with the inner side wall of the drying box, and the rotation centers of the tumbling barrel and the rotating rods are the same. Therefore, when the connecting rod rotates, the tumbling barrel can be driven to rotate on the inner side wall of the drying box through the rotating rods. Since several arc-shaped plates are fixedly connected to the inner side wall of the tumbling barrel and are inclined, when the tumbling barrel rotates, the materials can be continuously stirred and mixed by the arc-shaped plates, and the materials can continuously tumble inside the drying box. Moreover, by using the ventilation holes provided in the arc-shaped plates, the internal air flow can be guided to the tail of the drying box, so that the air flow impacts the materials again. When impacting, the air flow turns and is diverted to the initial position, which can generate different turbulent flow effects inside the drying box. In this way, the fluidity of the materials and the air flow is increased; the contact area between the materials and the air is increased, thereby improving the drying efficiency and further promoting the rapid evaporation and discharge of the internal moisture.
[0017] Furthermore, the drying assembly includes a heating member for providing heat energy to the inside of the drying box, and a controller for controlling the operation of the heating member; the heating member is sleeved on the inner side wall of the drying box, and the heating member is rotationally engaged with the tumbling barrel.
[0018] Beneficial effects: The provided heating member provides heat energy to the inside of the drying box. Since the heating member is sleeved on the inner side wall of the drying box and is rotationally engaged with the tumbling barrel, the heating member will not be affected by the rotation of the tumbling barrel during the heating process. During the rotation of the tumbling barrel, the heat generated by the heating member can be evenly distributed throughout the drying box, and the rotation of the tumbling barrel causes the materials to continuously tumble and mix. Therefore, uniform drying of the materials can be achieved. This uniform drying not only improves the drying quality but also avoids problems such as local overheating or uneven drying that may occur in traditional drying methods.
[0019] Furthermore, the outer shell located outside the fan blades is arc-shaped, and a protective net is fixedly connected at the air inlet.
[0020] Beneficial effects: The arc-shaped design of the outer shell helps to guide the air flow to flow more smoothly, reducing the resistance and eddy current phenomena during the air flow. The design of the protective net can effectively prevent large-particle materials or foreign objects from entering the inside of the drying device, thereby protecting the components inside the device from damage.
[0021] Furthermore, an electromagnetic one-way valve is fixedly connected to the bottom of the feeding port, and a controller is used to control the operation of the electromagnetic one-way valve.
[0022] Beneficial effects: The addition of the electromagnetic one-way valve prevents the materials from being blown to the outside during the blowing of the material air flow; thus, the materials are always continuously dried inside the drying box.
[0023] Furthermore, the discharge port is located on the side of the drying box away from the air delivery component. A gate is hinged at the discharge port, and a handle is fixedly connected to the outer side wall of the gate; a gate opening component is provided at the hinged part of the discharge port and the gate.
[0024] Beneficial effects: Through the design of the gate and the handle, the operator can take out the materials from the inside of the drying box through the gate; when the gate is closed, it can closely fit the discharge port, effectively preventing impurities such as external dust and moisture from entering the inside of the drying box and maintaining the cleanliness and stability of the drying environment.
[0025] Furthermore, the gate opening component includes a third driving part for providing rotational force for the gate, and the controller is used to control the operation of the third driving part; the third driving part is embedded in the side wall of the drying box, and the output shaft of the third driving part is fixedly connected to the top of the gate.
[0026] Beneficial effects: By controlling the output shaft of the third driving part to rotate through the controller, since the output shaft is fixedly connected to the top of the gate, the gate can be driven to rotate through the third driving part, thereby realizing the automatic opening and closing of the gate; further improving the production efficiency and automation level.
[0027] Furthermore, a temperature and humidity sensor is fixedly connected to the inner side wall of the drying box on the side away from the feeding port, and the controller is used to receive the information of the temperature and humidity sensor; and control the operation of the first driving part, the second driving part, the third driving part and the heating part according to the information of the temperature and humidity sensor.
[0028] Beneficial effects: The temperature and humidity sensor can collect the temperature and humidity information inside the drying box in real time. The controller can accurately adjust various parameters in the drying process, such as the air supply volume, the heating temperature and the material flow rate, etc., according to the information of the temperature and humidity sensor, so as to realize the precise control of the drying process.
[0029] Furthermore, the diameters of the second gear and the third gear are both larger than the diameter of the first gear.
[0030] Beneficial effects: During the rotation of the fan blade, the rotation speed of the first gear is relatively fast; by setting the diameters of the second gear and the third gear to be larger than the diameter of the first gear, the torque can be reduced; the rotation speeds of the second gear and the third gear are reduced, so that the change of the position of the ventilation slot will not be too fast, increasing the air flow time and further improving the drying efficiency.
[0031] Furthermore, anti-slip pads are fixedly connected to the bottoms of the support rods, and a blocking net for blocking the outflow of materials is fixedly connected to the bottom of the air outlet.
[0032] Beneficial effects: The design of the anti-slip mat can effectively increase the friction between the device and the ground, prevent the device from sliding or shifting during operation due to vibration or external forces, thus ensuring the stability and safety of the drying device. The design of the blocked mesh can ensure that during the drying process, the material will not accidentally flow out of the air outlet, causing waste or environmental pollution.

Specific Embodiments
[0040] The following is a further detailed description through specific embodiments:
[0041] Embodiment 1:
[0042] As shown in the Figures 1-4 drawing: A high-efficiency drying device for dry mortar production includes a drying box 1. Feeding ports and discharging ports are respectively opened on both sides of the drying box 1. The feeding port communicates with the top of the drying box 1. A plurality of support rods 2 are fixedly connected to the bottom of the drying box 1 by bolts. Inside the drying box 1, there is a tumbling assembly for tumbling the material and a drying assembly for drying the material; outside the drying box 1 and near one side of the feeding port, there is an air conveying assembly for conveying gas into the drying box 1.
[0043] As Figure 2 and Figure 4 shown, the gas transmission component includes a controller, a housing 8, and a first driving member for providing a bi-directional rotational force. In this embodiment, the first driving member is a first motor 3, and the controller is used to control the operation of the first motor 3; a first gear 4 is coaxially bolted and fixed to the output shaft of the first motor 3 close to the drying box 1, the first gear 4 meshes with a second gear 5, and the second gear 5 meshes with a third gear 6; a plurality of fan blades 7 are bolted and fixed to the output shaft of the first motor 3 away from the first gear 4; the fan blades 7, the first motor 3, the first gear 4, the second gear 5, and the third gear 6 are all located inside the housing 8; an air inlet is formed on the side wall of the housing 8 close to the fan blades 7; the housing 8 is bolted and fixed to the outer side wall on the left side of the drying box 1, the first motor 3 is bolted and fixed to the inner bottom wall of the housing 8, and both the second gear 5 and the third gear 6 are rotationally matched with the inner side wall of the housing 8.
[0044] A plurality of ventilation grooves are formed along the circumferential direction on one side of the second gear 5 and the third gear 6 close to the housing 8, and the ventilation grooves communicate with the side away from the housing 8 of both the second gear 5 and the third gear 6. Both the drying box 1 and the housing 8 are provided with figure-eight openings communicating with the ventilation grooves, and an air outlet is formed at the top of the drying box 1 away from the feeding port. The diameters of both the second gear 5 and the third gear 6 are larger than the diameter of the first gear 4.
[0045] As Figure 2 、 Figure 3 and Figure 5 shown, the tumbling component includes a tumbling barrel 9 and a second driving member for providing a driving force. In this embodiment, the second driving member is a second motor 10, and the controller is used to control the operation of the second motor 10; the second motor 10 is bolted and fixed to the outer side wall on the right side of the drying box 1, and the output shaft of the second motor 10 extends into the drying box 1 and is coaxially bolted and fixed to a connecting rod 11; the connecting rod 11 is rotationally matched with the drying box 1, and a plurality of rotating rods 12 are bolted and fixed to one end of the connecting rod 11 away from the second motor 10; one ends of the rotating rods 12 away from the connecting rod 11 are bolted and fixed to the inner side wall of the tumbling barrel 9, and openings communicating with the drying box 1 are formed on both sides of the tumbling barrel 9; the tumbling barrel 9 is rotationally matched with the inner side wall of the drying box 1, and a plurality of inclined arc-shaped plates 13 are bolted and fixed to the inner side wall of the tumbling barrel 9 along its length direction; a plurality of ventilation holes are formed in the side wall in the length direction of the arc-shaped plate 13, and a sealing net for blocking the inflow of materials is fixedly adhered to the outside of each ventilation hole. The tumbling barrel 9 and the rotating rods 12 have the same rotation center.
[0046] The second motor 10 drives the connecting rod 11 to rotate. Since the connecting rod 11 is rotationally engaged with the drying box 1, several rotating rods 12 are fixedly connected to the connecting rod 11 by bolts. The rotating rods 12 are fixedly connected to the inner wall of the tumbling barrel 9 by bolts. The tumbling barrel 9 is rotationally engaged with the inner wall of the drying box 1, and the centers of rotation of the tumbling barrel 9 and the rotating rods 12 are the same. Therefore, when the connecting rod 11 rotates, the tumbling barrel 9 can be driven to rotate on the inner wall of the drying box 1 through the rotating rods 12. Since several inclined arc-shaped plates 13 are fixedly connected to the inner wall of the tumbling barrel 9 by bolts, when the tumbling barrel 9 rotates, the mortar can be continuously stirred and mixed through the arc-shaped plates 13, and the mortar can continuously tumble inside the drying box 1. Moreover, by using the ventilation holes provided in the arc-shaped plates 13, the internal air flow can be guided to the tail of the drying box 1, so that the air flow impacts the material again. When impacting, the air flow turns and is diverted to the initial position, which can generate different turbulent effects inside the drying box 1. In this way, the fluidity of the mortar and the air flow is increased. When air enters the tumbling barrel 9, the contact area between the mortar and the air is increased, thereby improving the drying efficiency and further promoting the rapid evaporation and discharge of internal moisture.
[0047] As Figure 2 shown, the drying assembly includes a heating element for providing heat energy to the inside of the drying box 1. In this embodiment, the heating element is a heating tube 14, and the controller is used to control the operation of the heating tube 14. The heating tube 14 is sleeved on the inner wall of the drying box 1 and is rotationally engaged with the tumbling barrel 9.
[0048] The heating tube 14 provides heat energy to the inside of the drying box 1. Since the heating tube 14 is sleeved on the inner wall of the drying box 1 and is rotationally engaged with the tumbling barrel 9, the heating tube 14 will not be affected by the rotation of the tumbling barrel 9 during the heating process. During the rotation of the tumbling barrel 9, the heat generated by the heating tube 14 can be evenly distributed throughout the drying box 1, and the rotation of the tumbling barrel 9 causes the material to continuously tumble and mix. Therefore, uniform drying of the material can be achieved. This uniform drying not only improves the drying quality but also avoids problems such as local overheating or uneven drying that may occur in traditional drying methods.
[0049] The specific implementation process is as follows: When mortar drying work needs to be carried out, the mortar is fed into the inside of the drying box 1 through the feeding port; As Figure 2As shown in the figure, the first motor 3 drives the fan blade 7 to rotate. Since the outer shell 8 is sleeved outside the fan blade 7 and the air inlet is opened on the outer shell 8, when the fan blade 7 rotates, an air flow will be generated to suck the outside air into the inside of the outer shell 8. Since the output shaft at the other end of the first motor 3 is coaxially bolted to the first gear 4, the first gear 4 meshes with the second gear 5, and the second gear 5 meshes with the third gear 6. Therefore, when the first gear 4 rotates, it can drive the meshing second gear 5 to rotate, and the second gear 5 drives the third gear 6 to rotate.
[0050] As Figure 4 shown, since a plurality of ventilation grooves are provided along the circumferential direction on the sides of the second gear 5 and the third gear 6 close to the outer shell 8, and the ventilation grooves communicate with the sides of the second gear 5 and the third gear 6 away from the outer shell 8, and the drying box 1 and the outer shell 8 are both provided with figure-eight openings communicating with the ventilation grooves. Therefore, when the outside air is blown into the outer shell 8, the air can be blown into the inside of the drying box 1 through the provided ventilation grooves and figure-eight openings. Through this special design, when the outside air flow is sucked into the inside of the outer shell 8, the conveying channel is narrowed through the ventilation grooves, which can increase a certain flow rate of the air flow, thereby generating an impact force. When the air flow is transmitted to contact with the arc-shaped plate 13, the auxiliary materials are blown and flowed, thereby avoiding excessive accumulation of the materials; it can further reduce the time and cost of manual cleaning. This design enables the air flow to have stronger power when entering the drying box 1, and can more effectively penetrate and blow the mortar layer to accelerate the evaporation of moisture.
[0051] Moreover, due to the continuous rotation of the second gear 5 and the third gear 6, the position where the ventilation groove communicates with the figure-eight opening is constantly changing. This change directly leads to the diversification of the inlet angle and direction of the air flow entering the drying box 1. When the ventilation groove moves along the figure-eight path, it will point to each corner and area inside the drying box 1 at different time points, thereby guiding the external air flow to penetrate and fill the entire drying space from multiple distinct angles and directions. This multi-directional air flow distribution mode not only broadens the coverage range of the air flow, but also effectively reduces the drying dead corners that may be caused by traditional unidirectional or fixed-angle air flows, ensuring the comprehensiveness and efficiency of the drying process. The superimposed turbulent flow effect generated by the interaction of multi-directional air flows can further improve the drying efficiency. By combining the dynamic air flow path and the turbulent flow effect, the laminar flow state in the air flow can be broken, promoting the faster and more uniform exchange and transfer of moisture, thereby effectively reducing the local unevenness, and enabling the materials to be dried efficiently. The materials follow the air flow and continuously circulate inside the drying box 1. After the air flow is transmitted into the inside of the drying box 1, it continuously blows the mortar, thereby taking out the moisture.
[0052] Moreover, since the diameters of the second gear 5 and the third gear 6 are both larger than that of the first gear 4, the position where the air flow is transmitted can be gradually expanded, thereby increasing the air flow transmission volume. Also, during the rotation of the fan blade 7, the rotation speed of the first gear 4 is relatively fast. By setting the diameters of the second gear 5 and the third gear 6 to be larger than that of the first gear 4, its torque can be reduced, the rotation speeds of the second gear 5 and the third gear 6 can be lowered, so that the change of the ventilation slot position will not be too fast, increasing the air flow circulation time and further improving the drying efficiency.
[0053] Meanwhile, through the design of the tumbling barrel 9, the mortar can be mixed and stirred in the drying box 1, so as to be evenly purged by the air flow, further improving the uniformity of the drying effect. During this process, the heating tube 14 will generate a heating effect on the inside of the drying box 1, which not only improves the drying efficiency, but also ensures the uniform heating of the mortar surface and the evaporation of moisture. Through these synergistic effects, the external transmitted air flow generates a thermal effect, so that the external cold air flow becomes a hot air flow when transmitted to the inside, and can continuously circulate in the drying box 1, making the internal heat be continuously transferred and diffused, thereby drying the mortar efficiently. This synergistic effect not only accelerates the drying process, but also improves the drying quality, ensuring the dryness and performance of the mortar.
[0054] Moreover, due to the special shape design of the arc-shaped plate 13, when the air flow generates an impact force and flows through these special-shaped arc-shaped plates 13, it can make the arc-shaped plate 13 generate an auxiliary rotation effect, thereby generating an auxiliary rotational force on the tumbling barrel 9. Then, by using the ventilation holes, the air flow is continuously guided and circulated repeatedly, so that the internal thermal environment of the drying box 1 is continuously transmitted. This means that not only can the mortar surface receive heat from all directions faster and achieve rapid temperature rise, but also the moisture inside it can be more evenly evaporated under the action of dynamic turbulence, avoiding problems such as local overheating or uneven drying.
[0055] Embodiment 2:
[0056] As shown in the Figure 2 appendix, the difference from the above embodiment is that the outer shell 8 located outside the fan blade 7 is arc-shaped, and a protective net 15 is fixedly bonded at the air inlet.
[0057] The specific implementation process is as follows: The arc-shaped design of the outer shell 8 helps to guide the air flow to flow more smoothly, reducing the resistance and eddy current phenomena during the air flow movement. The design of the protective net 15 can effectively prevent plastic films, feathers or other foreign objects floating in the air from entering the inside of the drying device, thereby protecting the components inside the device from damage.
[0058] Embodiment 3:
[0059] As shown in the Figure 2As shown in the figure, the difference from the above embodiment is that an electromagnetic one-way valve 16 is fixedly connected to the bottom of the feeding port by bolts, and the controller is used to control the operation of the electromagnetic one-way valve 16.
[0060] The specific implementation process is as follows: The design of the electromagnetic one-way valve 16 is added to prevent the material from being blown to the outside during the blowing of the material air flow; thus, the material is always continuously dried in the drying box 1.
[0061] Embodiment 4:
[0062] As shown in the appendix Figure 1 and Figure 2 As shown in the figure, the difference from the above embodiment is that the discharge port is located on the side of the drying box 1 away from the air delivery component. A gate 17 is hinged at the discharge port, and a handle 18 is fixedly connected to the outer side wall of the gate 17 by bolts; an opening gate component is provided at the hinge of the discharge port and the gate 17; the opening gate component includes a third driving member for providing a rotational force for the gate 17. In this embodiment, the third driving member is selected as the third motor 19, and the controller is used to control the operation of the third motor 19; the third motor 19 is embedded in the side wall of the drying box 1, and the output shaft of the third driving member is fixedly connected to the top of the gate 17 by bolts.
[0063] The specific implementation process is as follows: Through the design of the gate 17 and the handle 18, the operator can take out the material from the inside of the drying box 1 through the gate 17; when the gate 17 is closed, it can closely fit the discharge port, effectively preventing external dust, moisture and other impurities from entering the inside of the drying box 1, and maintaining the cleanliness and stability of the drying environment.
