[0046] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0047] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0048] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0049] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] The present invention provides a drying box suitable for drying various materials, such as granular, powdery or block materials in the food, chemical, pharmaceutical and other industries.

[0052] like Figures 1 to 3 as well as Figure 9 As shown, the drying oven provided by the present invention comprises:

[0053] A box body 121 and a roller portion 122 disposed on the box body 121, wherein the roller portion 122 includes a roller shaft 1223, a roller body 1221 and a roller slide cover 1222, wherein the roller slide cover 1222 and the roller body 1221 are respectively sleeved on the roller shaft 1223, and the roller body 1221 has a first opening 12211, and the roller body 1221 is connected to the box body 121 through the first opening 12211;

[0054] The roller slide cover 1222 can rotate along the roller shaft 1223 and close or open the first opening 12211. When the roller slide cover 1222 closes the first opening 12211, the roller slide cover 1222 forms a transmission connection with the roller body 1221; when the roller slide cover 1222 opens the first opening 12211, the roller slide cover 1222 is disengaged from the roller body 1221.

[0055] As Figure 1 and Figure 9 shown, the drying oven includes a box body 121 and a drum part 122. The box body 121 constitutes the main structure of the drying oven, and its internal space is used to accommodate the drum part 122 and other related structures. The material of the box body 121 can have good heat preservation performance and certain corrosion resistance, which can ensure the drying efficiency and safety.

[0056] As Figure 6 shown, the drum part 122 includes a drum shaft 1223, a drum body 1221 and a drum sliding cover 1222. The drum body 1221 is usually designed to be cylindrical or similar in shape, and is provided with a space for loading materials to be dried inside. Vent holes or vent layers are provided on both the side and bottom of the drum body 1221, so that the drying gas in the box body 121 can uniformly penetrate the materials and achieve efficient drying. A first opening 12211 is provided at one end of the drum body 1221 for the entry and exit of materials.

[0057] As Figure 6 shown, the drum sliding cover 1222 and the drum body 1221 are respectively sleeved on the drum shaft 1223. The drum sliding cover 1222 can rotate relative to the drum body 1221 along the drum shaft 1223, and open or close the first opening 12211 on the drum body 1221, thereby controlling the communication state between the drum body 1221 and the box body 121.

[0058] Specifically, when the drum sliding cover 1222 rotates forward to close the first opening 12211, the drum sliding cover 1222 forms a driving connection with the drum body 1221. That is, a driving force transmission path is formed between the drum sliding cover 1222 - the drum body 1221. At this time, under the drive of the drive structure, the drum sliding cover 1222 can drive the drum body 1221 to rotate together, so that the materials to be dried in the drum body 1221 can be fully and evenly contacted with the drying gas, thereby achieving a better drying effect.

[0059] Moreover, the rotation of the drum body 1221 not only promotes the full mixing of the drying gas and the materials to be dried, but also increases the gas renewal rate on the surface of the materials to be dried, helps to remove the moisture or volatile components in the materials to be dried, and improves the drying efficiency.

[0060] When the drum sliding cover 1222 rotates in the reverse direction to open the first opening 12211, the drum sliding cover 1222 is disengaged from the transmission connection with the drum body 1221. That is, a transmission path for driving force cannot be formed between the drum sliding cover 1222 and the drum body 1221, that is, the drum body 1221 cannot rotate. At this time, the drum body 1221 communicates with the box body 121 through the first opening 12211, and the material to be dried can be loaded or the dried material can be unloaded through the first opening 12211, so as to facilitate the subsequent cycle of the drying process, speed up the drying rhythm, and improve the drying efficiency.

[0061] In this way, by using the rotation of the drum sliding cover 1222, the first opening 12211 can be closed or opened, so as to adjust the communication state between the drum body 1221 and the box body 121, so as to realize reliable drying and convenient entry and exit of materials, and improve the flexibility and efficiency of the drying operation. This design not only facilitates the loading and unloading of materials, but also enables continuous processing of materials without interrupting the drying process. Moreover, reliable sealing and convenient opening of the first opening 12211 are realized, avoiding gas leakage and material pollution during the drying process.

[0062] In addition, when the drum sliding cover 1222 closes the first opening 12211, the drum sliding cover 1222 forms a transmission connection with the drum body 1221. At this time, the drum body 1221 can rotate together under the drive of the drum sliding cover 1222 without additionally setting a drive source, saving the layout cost and reducing the space occupation inside the drying box, which is convenient for the miniaturization development of the drying box.

[0063] In one embodiment, a stirring member such as a rotating blade or a stirring shaft can be added inside the drum body 1221, which can improve the uniformity and drying efficiency of the material to be dried during the drying process.

[0064] In another embodiment, a temperature monitoring device and a control device can be added inside the box body 121 to monitor the temperature inside the box body 121 in real time and automatically adjust the heating power as needed to maintain a constant drying temperature, so as to meet the drying requirements of different materials to be dried.

[0065] In still another embodiment, a sealing strip or a gasket can be added between the drum sliding cover 1222 and the drum body 1221 to further improve the sealing performance of the first opening 12211.

[0066] In the drying box of the present invention, the drying gas in the box body 121 can directly contact the material to be dried through the breathable structure or pores of the drum body 1221; or the drying gas can also be directly connected to the central axis of the drum body 1221, so that the drying gas is transmitted from the central axis of the drum body 1221 to the material to be dried, and both can achieve fast and uniform drying.

[0067] Optionally, a driving part 3 is further included, and the roller part 122 further includes a transmission member 1224, one end of the transmission member 1224 is connected to the driving end of the driving part 3, and the other end of the transmission member 1224 is connected to the roller sliding cover 1222;

[0068] Under the drive of the driving unit 3 , the transmission member 1224 can drive the roller sliding cover 1222 to rotate in both directions.

[0069] Specifically, the driving unit 3 includes a driving motor, a chain sprocket, and a driving gear, etc., so that the driving force of the driving motor can be transmitted to the driving gear through the chain sprocket, and the driving gear is connected to the transmission member 1224 in a transmission manner, so as to achieve reliable transmission of the driving force of the driving unit 3-transmission member 1224. In addition, the driving unit 3 can also include a driving motor and a transmission gear set, which can also achieve reliable transmission of the driving force.

[0070] Among them, the driving part 3 is usually arranged on the outside of the box body 121. For example, the driving part 3 can be arranged on the outer wall of the box body 121. This can facilitate the reliable transmission of the driving force while avoiding the high temperature inside the box body 121 from affecting the normal operation of the driving part 3. It can also reduce the space occupied inside the box body 121, which is convenient for the miniaturization of the drying box.

[0071] like Figure 6 and Figure 8 As shown, the transmission member 1224 may include a gear 12241, a dial 12242 and a pin 12243, and the gear 12241 is transmission-connected to the driving end of the driving unit 3 so as to transmit the driving force of the driving unit 3 to the roller slide cover 1222 through the gear 12241, the dial 12242 and the pin 12243, thereby driving the rotation of the roller slide cover 1222.

[0072] Specifically, under the positive drive of the driving unit 3, the driving unit 3 can drive the roller slide cover 1222 to rotate positively to close the first opening 12211 through the gear 12241, the dial 12242 and the pin 12243, at which time the material to be dried in the roller body 1221 can be fully mixed with the drying gas.

[0073] Under the reverse drive of the driving unit 3, the driving unit 3 can drive the roller slide cover 1222 to rotate in the opposite direction to open the first opening 12211 through the gear 12241, the dial 12242 and the pin 12243. At this time, the roller body 1221 is connected with the box body 121 through the first opening 12211, and the material to be dried can be loaded or the dried material can be unloaded through the first opening 12211.

[0074] Among them, the forward drive and reverse drive of the drive unit 3 can respectively correspond to the forward rotation and reverse rotation of the drive motor. Under the forward drive of the drive unit 3, the drum sliding cover 1222 can rotate forward; under the reverse drive of the drive unit 3, the drum sliding cover 1222 can rotate in reverse.

[0075] Thus, the introduction of the drive unit 3 and the transmission member 1224 enables the opening and closing operation of the drum sliding cover 1222 to be automatically controlled, eliminating the need for manual operation, reducing the labor intensity, and improving the drying efficiency. The automatic control also makes the opening and closing operation of the drum sliding cover 1222 more convenient, avoiding the risk of misoperation that may be caused by manual operation, and improving the safety of the drying oven.

[0076] Optionally, the drum part 122 further includes a reverse rotation locking member 1225, which is arranged on the drum shaft 1223 and is used to control the one-way rotation of the drum body 1221.

[0077] As Figure 6 and Figure 7 shown, the reverse rotation locking member 1225 can be a one-way rotating bearing, a ratchet and pawl mechanism, a wedge-type one-way clutch or other one-way rotating structures, which can ensure that the drum body 1221 can only rotate in a predetermined single rotation direction during operation, avoiding drying oven failures or safety accidents caused by accidental reverse rotation, and also being able to prevent the drum body 1221 from shaking or shifting, ensuring the stability of the drum body 1221 during the drying process, and thus ensuring the uniform distribution and sufficient drying of the material to be dried inside the drum body 1221.

[0078] Among them, the setting of the reverse rotation locking member 1225 makes the drum body 1221 unable to rotate in the direction opposite to the predetermined single rotation direction. That is, when the drum sliding cover 1222 rotates in reverse under the drive of the drive unit 3, the drum body 1221 will not rotate in reverse, thus facilitating the opening of the first opening 12211.

[0079] Among them, according to the actual design, it can be set that the drum shaft 1223 rotates or does not rotate, and the reverse rotation locking member 1225 is connected to the drum body 1221 through a rotating sleeve 1228, so that the drum body 1221 can only rotate in a predetermined single rotation direction and will not rotate in reverse.

[0080] Optionally, the drum part 122 further includes an elastic member 1226, one end of the elastic member 1226 is connected to the drum body 1221, and the other end of the elastic member 1226 is connected to the drum sliding cover 1222;

[0081] Under the reverse drive of the driving part 3, the transmission part 1224 can drive the drum sliding cover 1222 to rotate reversely and open the first opening 12211, and the elastic part 1226 is in a stretched state; under the forward drive of the driving part 3, the transmission part 1224 can first drive the drum sliding cover 1222 to rotate forward to close the first opening 12211, and then drive the drum sliding cover 1222 and the drum body 1221 to rotate together, and the elastic part 1226 returns to its initial state.

[0082] As Figure 5 and Figure 6 shown, the drum sliding cover 1222 can include a sliding cover piece 12221 and a sliding cover support 12222. The sliding cover support 12222 is arranged on the rotating sleeve 1228 and connected to the transmission part 1224. The sliding cover piece 12221 is fixedly connected to the sliding cover support 12222, so that the driving force can be transmitted from the transmission part 1224 to the sliding cover support 12222 and drive the sliding cover support 12222 and the sliding cover piece 12221 to rotate together.

[0083] Among them, the elastic part 1226 can be a single or multiple springs. One end of the elastic part 1226 is connected to the drum body 1221, and the other end of the elastic part 1226 is connected to the drum sliding cover 1222. When the drum sliding cover 1222 rotates, the drum sliding cover 1222 can stretch the elastic part 1226 and cause elastic deformation of the elastic part 1226.

[0084] Specifically, under the reverse drive of the driving part 3, the driving part 3 can drive the drum sliding cover 1222 to rotate reversely through the transmission part 1224 to open the first opening 12211. At this time, materials can be loaded and unloaded through the first opening 12211. Moreover, the reverse rotation of the drum sliding cover 1222 will also stretch the elastic part 1226, causing elastic deformation of the elastic part 1226. At this time, the elastic force of the elastic part 1226 cooperates with the reverse rotation locking part 1225 to avoid the shaking of the drum body 1221 and enable the drum body 1221 to maintain a stable stationary state, thereby facilitating the reliability and safety of material loading and unloading.

[0085] In particular, when the drum body 1221 rotates to make the first opening 12211 opposite to the discharge port below the box body 121, that is, when discharging the dried materials, the shaking of the drum body 1221 will not only cause the first opening 12211 to shift and make the first opening 12211 unable to be completely opposite to the discharge port of the box body 121, but also drive the internal dried materials to do a scattering movement, all of which will affect the discharging efficiency. At this time, the cooperation between the elastic force of the elastic part 1226 and the reverse rotation locking part 1225 can avoid the shaking of the drum body 1221, thereby ensuring the discharging efficiency.

[0086] Under the forward drive of the drive unit 3, the drive unit 3 can first drive the drum sliding cover 1222 to rotate forward through the transmission member 1224 to close the first opening 12211, so that the drum sliding cover 1222 forms a transmission connection with the drum body 1221, and the elastic member 1226 returns to its initial state. That is, before the drum sliding cover 1222 rotates back to close the first opening 12211, the elastic member 1226 is in a stretched state. The cooperation between the elastic force of the elastic member 1226 and the reverse locking member 1225 can prevent the drum body 1221 from shaking and enable the drum body 1221 to maintain a stable stationary state. After that, the drive unit 3 can drive the drum sliding cover 1222 and the drum body 1221 to rotate together through the transmission member 1224, and fully mix the material to be dried and the drying gas.

[0087] In addition, the introduction of the elastic member 1226 also ensures a smooth transition of the drum sliding cover 1222 during the opening and closing processes, avoiding impacts and vibrations caused by sudden opening or closing, thereby enhancing the stability and reliability of the operation of the drying box.

[0088] Optionally, the end of the drum body 1221 has a protruding portion 12212. When the drum sliding cover 1222 closes the first opening 12211, the drum sliding cover 1222 abuts against the protruding portion 12212.

[0089] As Figure 6 shown, the protruding portion 12212 is located at at least one end of the drum body 1221 and protrudes outward along the axial direction of the drum body 1221. When the drum sliding cover 1222 rotates to close the first opening 12211, the drum sliding cover 1222 can abut against the protruding portion 12212, so that the drum sliding cover 1222 forms a transmission connection with the drum body 1221, enabling the drum sliding cover 1222 to drive the drum body 1221 to rotate together and achieve full mixing of the material to be dried and the drying gas.

[0090] Among them, usually one protruding portion 12212 is provided at each of the two ends of the drum body 1221, and the connection line of the two protruding portions 12212 is parallel to the axis of the drum body 1221. When the drum sliding cover 1222 rotates to close the first opening 12211, the drum sliding cover 1222 can abut against the protruding portions 12212 on both sides and form a reliable transmission connection between the drum sliding cover 1222 - the drum body 1221.

[0091] In another embodiment, an arc-shaped groove may be formed on either the drum body 1221 or the drum sliding cover 1222, and a protrusion is provided on the other of the drum body 1221 and the drum sliding cover 1222, and the protrusion can slide within the arc-shaped groove. When the protrusion slides to one end of the arc-shaped groove, i.e., the limiting area, the drum sliding cover 1222 closes the first opening 12211 and forms a transmission connection with the drum body 1221; when the protrusion slides in the reverse direction and leaves the limiting area, the drum sliding cover 1222 opens the first opening 12211 and disengages from the transmission connection with the drum body 1221.

[0092] Optionally, it further includes a first hopper 21 and a second hopper 22, the first hopper 21 and the second hopper 22 are respectively connected to the box body 121, and the box body 121 has a second opening and a third opening;

[0093] When the drum sliding cover 1222 closes the first opening 12211, the material to be dried can be dried within the drum body 1221; when the drum sliding cover 1222 opens the first opening 12211, the material to be dried can enter the drum body 1221 through the first hopper 21, the second opening and the first opening 12211, or the dried material can be discharged from the drum body 1221 through the first opening 12211, the third opening and the second hopper 22.

[0094] As Figure 6 shown, when the drum sliding cover 1222 closes the first opening 12211, a closed drying environment is formed inside the drum body 1221, and the material to be dried can be efficiently and uniformly dried in this space.

[0095] When it is necessary to load new material to be dried or discharge the dried material, the drum sliding cover 1222 can open the first opening 12211. At this time, the material to be dried can conveniently enter the inside of the drum body 1221 through the first hopper 21, the second opening and the first opening 12211, or the dried material can be conveniently discharged from the inside of the drum body 1221 through the first opening 12211, the third opening and the second hopper 22. This design greatly simplifies the material handling process and improves the efficiency of the drying operation.

[0096] By introducing the hopper assembly 2 with the first hopper 21 and the second hopper 22, the drying box of the present invention can realize continuous loading and unloading of materials, avoid interruption and waiting time in material handling in traditional drying equipment, and improve the utilization rate and production efficiency of the drying box.

[0097] Among them, the independent design of the first hopper 21 and the second hopper 22 enables the materials to be loaded and unloaded separately, further enhancing the flexibility of material handling. The first hopper 21 and the second hopper 22 can be arranged on two adjacent sides of the box body 121, or the first hopper 21 and the second hopper 22 can also be arranged on two opposite sides of the box body 121.

[0098] Optionally, it further includes a first sealing plate 123, and the first sealing plate 123 is movably connected to the first end of the box body 121 and can close or open the second opening.

[0099] And / or, it further includes a second sealing plate, and the second sealing plate is movably connected to the second end of the box body 121 and can close or open the third opening.

[0100] Such as Figure 2 and Figure 9 As shown, the first sealing plate 123 can be slidably or rotatably connected to the second opening of the box body 121, so that the first sealing plate 123 can open the second opening for loading the material to be dried, or the first sealing plate 123 can close the second opening for reliable drying of the material to be dried.

[0101] Similarly, the second sealing plate can also be slidably or rotatably connected to the third opening of the box body 121, so that the second sealing plate can open the third opening for discharging the dried material, or the second sealing plate can close the third opening for reliable drying of the material to be dried.

[0102] Optionally, the hopper assembly 2 further includes a first weighing hopper and a second weighing hopper. The first weighing hopper is arranged on the side of the first hopper 21 away from the drying box, and the second weighing hopper is arranged on the side of the second hopper 22 away from the drying box.

[0103] Specifically, the first weighing hopper is used to weigh the material to be dried before drying, and the second weighing hopper is used to weigh the dried material after drying. In this way, the moisture content in the material to be dried can be judged.

[0104] Optionally, the box body 121 is provided with a first positioning member 1213, and the first positioning member 1213 is used to position the feeding station and the discharging station of the roller body 1221.

[0105] Specifically, the first positioning member 1213 includes, but is not limited to, an induction switch and a positioning piece. During the rotation of the drum body 1221, the induction switch can sense its rotation and respond when it rotates to the loading station and the unloading station, so as to indicate that the drum body 1221 is exactly at the loading station or the unloading station. Alternatively, during the rotation of the drum body 1221, the positioning piece can form an obstruction when it rotates to the loading station and the unloading station, and can also indicate that the drum body 1221 is exactly at the loading station or the unloading station, both of which can ensure the reliability of material loading and discharging.

[0106] As Figure 3 shown, when the drum body 1221 rotates to the loading station, the first opening 12211 is opposite to the second opening of the box body 121, and the material to be dried can be loaded; when the drum body 1221 rotates to the unloading station, the first opening 12211 is opposite to the third opening of the box body 121, and the dried material can be discharged. During the rotation of the drum body 1221, the first positioning member 1213 can sense these two working positions, thus ensuring the reliability of material loading and unloading.

[0107] Optionally, drying gas flows inside the drum shaft 1223, and the outer periphery of the drum shaft 1223 has a fourth opening 12231 for transmitting the drying gas to the drum body 1221.

[0108] As Figure 4 shown, the design of the drum shaft 1223 enables the drying gas inside the drum shaft 1223 to directly enter the inside of the drum body 1221 through the fourth opening 12231 without passing through additional pipelines or spaces, thereby reducing the energy loss and time delay during the transmission of the drying gas, and also ensuring that the drying gas can be quickly and evenly distributed inside the drum body 1221, improving the contact efficiency between the drying gas and the material to be dried and the drying effect.

[0109] The arrangement of the drum shaft 1223 not only realizes the direct transmission of the drying gas, but also makes the structure of the entire drying box more compact. The drum shaft 1223, as a bridge connecting the external drying source and the drum body 1221, effectively reduces the redundant space of the drying box and improves the space utilization rate.

[0110] Among them, by providing the fourth opening 12231 on the outer periphery of the drum shaft 1223, it can be ensured that the drying gas is evenly distributed inside the drum body 1221. This evenly distributed drying gas helps the material to be dried obtain a more consistent drying effect during the drying process, avoiding problems such as local overheating or insufficient drying.

[0111] Among them, according to the actual design, the fourth opening 12231 can be an independent strip-shaped opening, or a combination of multiple strip-shaped openings and circular openings.

[0112] As Figure 4 shown, the support 1227 can be used to fix the roller shaft 1223 for easy installation.

[0113] Optionally, a wind guiding member 12232 is provided on the outer periphery of the roller shaft 1223. The wind guiding member 12232 is located at the fourth opening 12231 and is used to guide the transmission of the drying gas.

[0114] And / or, a material guiding member 12233 is provided on the outer periphery of the roller shaft 1223. The material guiding member 12233 is used to guide the movement of the material to be dried.

[0115] As Figure 4 shown, one or more wind guiding members 12232 can be provided on the outer periphery of the roller shaft 1223. The wind guiding members 12232 are used to guide the drying gas flowing out from the fourth opening 12231 to ensure that the drying gas is evenly distributed inside the roller body 1221. This evenly distributed drying gas helps the material to be dried obtain a more consistent drying effect during the drying process, avoiding problems such as local overheating or insufficient drying. Among them, the wind guiding member 12232 can be a wind guiding plate, a wind guiding strip, a wind guiding piece, etc.

[0116] As Figure 4 shown, the material guiding member 12233 can guide the movement of the material to be dried, prevent the material to be dried from adhering to the roller shaft 1223, and thus ensure that the material to be dried can be fully mixed with the drying gas inside the roller body 1221 and achieve better drying.

[0117] Optionally, a first exhaust member 124 is further included. The box body 121 communicates with the outside through the first exhaust member 124.

[0118] As Figure 1 、 Figure 2 and Figure 9 shown, the first exhaust member 124 is used to connect the inside of the box body 121 with the outside, so that the humid gas inside the box body 121 can be discharged to the outside through the first exhaust member 124, ensuring that the inside of the roller body 1221 of the box body 121 is always dry first drying gas, thereby ensuring its drying effect. Among them, the first exhaust member 124 includes but is not limited to an exhaust port and an exhaust pipe.

[0119] Optionally, both the roller sliding cover 1222 and the roller body 1221 are in a sieve-like structure.

[0120] Specifically, the sieve-like structure enables the humid gas inside the drum body 1221 to be discharged and exhausted to the outside via the first exhaust member 124 of the drying chamber, so as to ensure that the gas inside the drum body 1221 is always dry, thereby guaranteeing its drying effect.

[0121] Among them, the design of the sieve holes only allows the humid gas to be discharged, while the materials cannot enter or exit, so as to avoid abnormal dropping of the materials.

[0122] Optionally, a detection unit is provided inside the box body 121, and the detection unit is used to detect the drying temperature of the drying chamber or the mass difference of the material to be dried before and after drying;

[0123] And / or, a heating unit is provided inside the box body 121, and the material to be dried can be dried by the heating unit inside the drum body 1221, so as to quickly remove the moisture in the material to be dried and improve the drying efficiency of the drying chamber. Among them, the heating unit may include one or more heating tubes, which is convenient for adjusting the drying temperature inside the box body 121 through the controller.

[0124] Specifically, the detection unit may be a temperature sensor, and the temperature sensor can detect the drying temperature inside the drying chamber in real time for the controller to control to adapt to different drying requirements. The detection unit may also be two mass sensors, and the two mass sensors respectively detect the mass of the material before and after drying, so as to obtain the moisture content in the material.

[0125] The present invention also provides a drying device, including a drying pipe and the drying chamber described above. A drying gas flows in the drying pipe, and the drying pipe is connected to the drying chamber to be able to transmit the drying gas to the drying chamber.

[0126] As Figure 1 shown, a drying gas flows in the first drying pipe 11. The drying gas includes but is not limited to normal temperature air, heated air and inert gas, and is used to provide the heat source or inert environment required for drying. One end of the first drying pipe 11 is connected to a heat source such as a heater or a blower, etc., and the other end is connected to the first drying chamber 12 to ensure that the drying gas can be smoothly transmitted to the inside of the first drying chamber 12. The connection between the first drying pipe 11 and the first drying chamber 12 enables the first drying assembly 1 having the first drying pipe 11 and the first drying chamber 12 to adapt to the drying requirements over a long distance, and also enhances the adaptability of the drying device.

[0127] Optionally, the drying pipe includes a plurality of pipes connected in sequence. Each pipe includes a pipe body 111, a heating member 112 and a heat dissipation member 113. The heating member 112 and the heat dissipation member 113 are arranged inside the pipe body 111, and the heat dissipation member 113 faces the heating member 112.

[0128] As Figure 1 and Figure 10 shown, the drying tube is provided with a plurality of pipes connected in sequence. The plurality of pipes jointly convey the drying gas and can also adapt to different conveying distances. Among them, each pipe can independently perform heating and heat dissipation operations to enable more uniform and efficient drying treatment of the material to be dried.

[0129] As Figure 10 shown, the heating member 112 can heat the drying gas flowing through the pipe, while the heat dissipation member 113 can effectively and evenly dissipate the heated drying gas, ensuring that the temperature of the drying gas in each stage of the pipe remains uniform, and further ensuring the temperature uniformity and consistency of the drying gas output by the drying tube.

[0130] Among them, the heating member 112 includes but is not limited to heaters and heating wires, and the heat dissipation member 113 includes but is not limited to heat sinks and fans. The heating member 112 and the heat dissipation member 113 are preferably made of materials with high temperature resistance and corrosion resistance, which can ensure the stability and reliability of the heating member 112 and the heat dissipation member 113 during long-term use.

[0131] In one embodiment, the heating temperature of each stage of the pipe can be set for independent control. That is, controllers are respectively arranged in each stage of the pipe. The controller can adjust the heating temperature of the heating member 112 and / or the heat dissipation effect of the heat dissipation member 113 according to actual needs, thereby realizing flexible control of the drying temperature. This flexible temperature control method enables the drying device to adapt to the needs of different materials to be dried and drying processes, improving the adaptability and flexibility of the drying device.

[0132] In addition, by precisely controlling the heating and heat dissipation processes of each stage of the pipe, it can be ensured that the material to be dried can achieve an ideal drying effect during the drying process, avoiding quality problems caused by too high or too low temperature.

[0133] Optionally, a temperature sensor 114 is further provided on the pipe body 111. The temperature sensor 114 is used to detect the temperature information inside the pipe and transmit the temperature information to the controller, so as to facilitate the controller to control the heating member 112 and the heat dissipation member 113, thereby meeting different drying requirements.

[0134] Optionally, the pipe body 111 includes an inner pipe 1111, an outer shell 1112, and a thermal insulation layer 1113. The thermal insulation layer 1113 is arranged between the inner pipe 1111 and the outer shell 1112.

[0135] Specifically, the three-layer setting of the pipeline body 111, on the one hand, strengthens the self-strength of the pipeline body 111 and avoids the leakage of dry gas caused by the rupture of the pipeline body 111; on the other hand, the multi-layer structure also enhances the heat preservation ability of the pipeline body 111, enabling the flowing dry gas to be stably maintained at a predetermined temperature.

[0136] As Figure 10 shown, sandwiching the heat preservation layer 1113 between the inner pipe 1111 and the outer shell 1112 can effectively reduce the heat dissipation, ensuring that the heat generated by the heating element 112 can be transferred to the dry gas flowing through the pipeline to the greatest extent, thereby improving the heating efficiency. This efficient heat utilization method not only speeds up the drying speed of the material to be dried but also significantly reduces the energy consumption, meeting the requirements of modern industry for energy conservation and emission reduction.

[0137] Among them, the inner pipe 1111 can be a stainless steel pipe, the outer shell 1112 can be a metal shell, and the heat preservation layer 1113 can be formed by using heat preservation materials such as glass wool and polyurethane.

[0138] Moreover, the heat preservation layer 1113 can also isolate the influence of external temperature fluctuations on the temperature of the inner pipe 1111, making the temperature inside the pipeline more stable, which is conducive to achieving precise control of the drying temperature. This stable temperature control environment ensures that the material to be dried can be evenly heated during the drying process, avoiding quality problems caused by temperature fluctuations.

[0139] In addition, the setting of the heat preservation layer 1113 also reduces the temperature difference between the inner pipe 1111 and the outer shell 1112, reducing the influence of thermal stress on the pipeline material, thereby extending the service life of the drying pipe. Also, the heat preservation layer 1113 can protect the inner pipe 1111 from external corrosion and mechanical damage, further improving the reliability and durability of the drying pipe.

[0140] Optionally, the drying device may further include a second drying pipe and a second drying box. The second drying gas flows in the second drying pipe. The second drying pipe and the second drying box are connected to be able to transmit the second drying gas to the second drying box. One side of the second drying box is communicated with the third opening, and the other side of the second drying box is connected to the second hopper.

[0141] As Figures 1 to 3 and Figure 10As shown, the second drying pipe and the second drying oven form a second drying assembly. The material to be dried is first dried for the first time in the first drying oven 12, and then dried for the second time in the second drying oven, so as to enhance the drying effect and meet different drying requirements. Among them, the first drying gas can be set as high-temperature air, and the second drying gas can be set as normal-temperature air, so that the material to be dried can be quickly dried in the first drying oven 12 first, and then cooled and dewatered in the second drying oven.

[0142] It should be noted that the second drying oven is similar in structure to the first drying oven 12, and the second drying pipe is similar in structure to the first drying pipe 11, which will not be elaborated here.

[0143] Optionally, the drying device further includes a first filter 13 and a first fan 14. One end of the first fan 14 is connected to the first filter 13, and the other end of the first fan 14 is connected to the first drying pipe 11, so that normal-temperature gas can be filtered by the first filter 13 and heated by the first fan 14 to obtain high-temperature first drying gas, and then transported into the first drying pipe 11.

[0144] Optionally, the drying device further includes a second filter and a second fan. One end of the second fan is connected to the second filter, and the other end of the second fan is connected to the second drying pipe, so that normal-temperature gas can be filtered by the second filter and dried by the second fan to obtain normal-temperature second drying gas, and then transported into the second drying pipe.

[0145] In the above embodiments, the differences between the embodiments are mainly described. As long as the different optimization features between the embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, it will not be elaborated here.
