[0003] The rotating drum of the drum dryer is a slightly inclined and rotatable cylindrical body. Wet materials enter from the upper part of one end, and dry materials are collected from the lower part of the other end. Hot air enters from the feeding end or the discharging end and exits from the upper part of the other end. The drum is equipped with forward scraping plates, so that the materials are continuously scooped up and sprinkled down during the rotation of the cylindrical body, making them fully contact with the hot air flow to improve the drying efficiency and move the materials forward. The wet components of the materials are vaporized by heat transfer from the drum wall during the rotation of the drum. The drum completes processes such as film formation, vaporization, and dehydration in one rotation cycle. The dried materials are scraped off by a scraper, conveyed by a screw to the finished product storage tank, and finally pulverized or directly packaged. Summary of the Invention

[0044] Advantageous Effects

[0045] The present application provides a vertical disk dryer. Through the above design, the problem that sticky materials cannot be dried is solved, the rotation and heating of the drying vertical disk are synchronized, and the vertical disk is made of metal with high thermal conductivity.

[0046] The vertical disk is conducive to the self-weight falling of the materials, not easy to accumulate, and no additional conveying is required. The drying task can be completed on both sides of each vertical disk. Compared with most horizontal disk dryers, the working heat exchange area is doubled. Since the inner cavity of the vertical disk can accommodate a large amount of steam, the production efficiency is greatly improved; when the size structures of each group of vertical disks are exactly the same, it is convenient for production and manufacturing; the processing cost of the dryer can be reduced. The size structures of the vertical disks can also be different. The different vertical disks can dry wet materials with different humidities, thereby improving the utilization rate of the drying disks, reducing the heat loss of the dryer, and improving the drying efficiency of the dryer.

[0047] The vertical disk is provided with a spike roller to crush the materials and prevent large pieces of materials from accumulating and blocking; the surface of the materials is prone to form a film and is not easy to dry. The spike roller pierces the film on the surface of the materials to improve the drying efficiency.

[0048] During the feeding and scraping processes, symmetrically arranged feeding pipes and scrapers are arranged on both sides of each vertical disk, maximizing the utilization of heat energy and the balance of forces, and having better dynamic balance than general dryers using only one side.

[0049] In the present application, an external conveyor auger device is provided. For general disk dryers, the produced materials do not require vacuum sealing, while the materials produced by this equipment require a vacuum environment. At the same time, the super strong viscosity of the materials easily causes the materials to block and adhere in general sealing equipment. Therefore, the designed external conveyor auger can not only stably convey the materials, but also be timely removed and replaced with a new conveyor auger when a failure occurs, greatly reducing the downtime of the factory during actual production due to material blockage.

The specification and claims do not distinguish components by the difference in terms, but by the difference in the functions of the components. As used throughout the specification and claims, the terms "comprising" or "including" are open-ended terms and should be interpreted as "including but not limited to". The subsequent description of the specification is for the purpose of implementing the preferred embodiments of the present application, but the description is for the general purpose of the specification and is not intended to limit the scope of the present application. The scope of protection of the present application shall be determined by the terms defined in the appended claims.

[0056] Refer to Figure 1 and Figure 2 , the present application provides a vertical disk 1 type dryer. It is used for drying wet materials. The dryer includes a drying system, a cloth system, and a scraping system. The drying system includes a vertically arranged vertical disk 1. The cloth system can transport the wet materials onto the vertical disk 1. The wet materials can adhere to the end faces on both sides of the vertical disk 1. The wet materials are processed by the vertical disk 1 to obtain dry materials; the scraping system is arranged in front of the cloth system in the material transportation direction.

[0057] In a specific embodiment, the vertical disk 1 is a disk-shaped structure or a flat plate-shaped structure. When using the vertical disk 1 for drying, the wet materials can be transported to the positions of the end faces on both sides of the vertical disk 1; and the wet materials will adhere to the end faces of the vertical disk 1. The wet materials are dried by the vertical disk 1, and the liquid components in the wet materials are evaporated and removed, thereby obtaining dry materials.

[0058] Refer to Figure 1 andFigure 2 The cloth conveying system transports the wet material onto the vertical plate 1, and then the vertical plate 1 rotates. While the vertical plate 1 is rotating, the vertical plate 1 dries the wet material into dry material and at the same time transports the dry material to the position of the scraping system. The scraping system is used to remove the dry material from the vertical plate 1. After the vertical plate 1 rotates past the scraping system, it will continue to rotate to the cloth conveying system, and the cloth conveying system transports the wet material onto the vertical plate 1 from which the dry material has been scraped. This process repeats, thereby realizing the transportation, drying of the wet material, and collection of the dry material.

[0059] Reference Figure 1 and Figure 2 Using the vertical plate 1 to dry the wet material can first attach the wet material to the two end faces of the vertical plate 1 respectively, enabling more wet material to adhere to the vertical plate 1, allowing the vertical plate 1 to process more wet material, thereby increasing the drying speed of the wet material and improving the drying efficiency of the dryer.

[0060] Reference Figure 1 and Figure 2 The vertical plate 1 can rotate in the vertical plane around its own axis.

[0061] Set the vertical plate 1 vertically so that the two end faces of the vertical plate 1 are in symmetrical positions. When the wet material adheres to the vertical plate 1, the wet material can adhere in a more symmetrical form. Therefore, the wet material on both sides of the vertical plate 1 can be dried in a more uniform form. The wet material on the two end faces of the vertical plate 1 can be dried at the same or similar time. Then, the scraping process can be carried out simultaneously and uniformly. This helps with the layout of the cloth conveying system and the scraping system. Further, the synchronous treatment of the wet material on the two end faces of the vertical plate 1 will make the vertical plate 1 more stable during rotation, improving the dynamic balance of the vertical plate 1. It improves the stability of the vertical plate 1 during rotation, reduces the possibility of the vertical plate 1 shifting during rotation, and improves the stability of the dryer during use.

[0062] Reference Figure 1 and Figure 2 When the vertical plate 1 rotates, the wet material adhering to the vertical plate 1 will rotate with the vertical plate 1. At this time, the wet material will be affected by the centrifugal force, and then the wet material will spread on the vertical plate 1, enabling the wet material to be laid out more evenly on the vertical plate 1, and further improving the movement stability of the vertical plate 1.

[0063] Reference Figure 1 and Figure 2 Preferably, the vertical plate 1 is a disc.

[0064] In a specific embodiment, the vertical disk 1 is a circular disk-shaped structure. Optionally for those skilled in the art, the vertical disk 1 is not limited to its specific shape, and setting the vertical disk 1 into shapes such as square, rectangle, trapezoid, sector, etc. are all alternative solutions in this application.

[0065] Preferably, the vertical disk 1 is a circular structure, which improves the dynamic balance of the vertical disk 1 in the rotating state and enhances the rotation stability of the vertical disk 1.

[0066] Further preferably, the vertical disk 1 is a hollow structure, and a heat source can be introduced into the interior of the vertical disk 1;

[0067] The heat source includes a heat source device that generates heat and a heat exchange medium, and the heat is transferred to the vertical disk 1 through the heat exchange medium.

[0068] The heat exchange medium includes a high-temperature fluid, preferably steam or hot oil.

[0069] Reference Figure 1 and Figure 2 , the interior of the vertical disk 1 is a hollow chamber, the heat source can enter the interior of the vertical disk 1, and then heat the vertical disk 1. The vertical disk 1 transfers the heat to the wet material to heat and dry the wet material, causing the liquid component in the wet material to evaporate. The drying treatment of the wet material is realized; and then dry material is obtained.

[0070] Further preferably, two or more than three vertical disks 1 are provided, and the multiple vertical disks 1 are connected in series with each other, and the interiors of the vertical disks 1 are communicated.

[0071] In a specific embodiment, specifically, the vertical disk 1 is provided with any number among 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.

[0072] Reference Figure 1 and Figure 2 , the multiple vertical disks 1 are connected in series, and the hollow chambers inside the vertical disks 1 are communicated. Therefore, the heat source can enter the interior of as many vertical disks 1 as connected through the connected vertical disks 1. It is convenient to heat the vertical disks 1. The heating efficiency of the heat source for the vertical disks 1 is improved.

[0073] A rotary joint 2 is provided at one end of the drying system, and an inlet pipe and an outlet pipe for the heat source circulation of the vertical disk 1 are connected to the rotary joint 2;

[0074] Preferably, the rotary joint 2 is rotatably connected to the vertical disk 1.

[0075] Reference Figure 1 and Figure 2, the rotary joint 2 is rotatably connected to the vertical disk 1. Therefore, after the heat source is transported to the inside of the vertical disk 1 through the rotary joint 2, the rotary joint 2 can continuously supply heat into the vertical disk 1, and the vertical disk 1 can also rotate.

[0076] Both the inlet pipe and the outlet pipe are connected to the heat source. The heat exchange medium enters the rotary joint 2 and the vertical disk 1 from the inlet pipe, and then exits the vertical disk 1 from the rotary joint 2 and the outlet pipe. The heat exchange medium circulates inside the vertical disk 1 for one week to achieve the heat exchange between the heat exchange medium and the vertical disk 1.

[0077] Reference Figure 1 and Figure 2 , the rotary joint 2 is used to connect the heat source to the vertical disk 1, so that the heat generated in the heat source can be transported to the continuously rotating vertical disk 1, enabling the vertical disk 1 to be heated while rotating, and further enabling the vertical disk 1 to dry and transport the wet material simultaneously. The purpose is to improve the drying efficiency of the vertical disk 1 for the wet material.

[0078] Reference Figure 1 and Figure 2 , the inlet pipe is connected to the hollow chamber inside the vertical disk 1 through a rotary connector, and the outlet pipe is connected to a cooling pipe 21 through a rotary connector. The cooling pipe 21 is located inside the vertical disk 1, and one end of the cooling pipe 21 away from the outlet pipe is located at a position near the lower end of the vertical disk 1;

[0079] Reference Figure 1 and Figure 2 , after the heat exchange medium enters the vertical disk 1, the heat in the heat exchange medium will be transferred to the vertical disk 1 and the wet material. Then, after the heat in the heat exchange medium is reduced and cooled, due to reasons such as thermal expansion and contraction, the cooled heat exchange medium will sink to the bottom position of the vertical disk 1. The end of the cooling pipe 21 is located at a position near the lower end of the vertical disk 1. Therefore, when the inlet pipe continuously supplies the heat exchange medium into the vertical disk 1, the cooled heat exchange medium will enter the cooling pipe 21 from the lower end position of the vertical disk 1, and then exit the vertical disk 1 from the outlet pipe. This cycle repeats, thereby enabling the heat exchange medium with high heat to continuously enter the vertical disk 1, and the cooled heat exchange medium to exit the vertical disk 1. The heat exchange medium can continuously heat and dry the vertical disk 1 and the wet material.

[0080] Further preferably, the inlet pipe and the outlet pipe are isolated and sealed at the rotary joint 2;

[0081] Reference Figure 1 and Figure 2, the rotary joint 2 isolates the inlet pipe and the discharge pipe, enabling the heat exchange medium to flow unidirectionally in the vertical disk 1, allowing the high-calorie heat exchange medium to enter the vertical disk 1 and the cooled heat exchange medium to be discharged from the vertical disk 1.

[0082] Further preferably, the inlet pipe is internally connected to all of the vertical disks 1; the ends of the cooling pipes 21 remote from the discharge pipe are respectively connected to positions near the lower ends of all of the vertical disks 1.

[0083] Reference Figure 1 and Figure 2 , a plurality of vertical disks 1 are provided. And the plurality of vertical disks 1 are all connected at positions close to the rotation center. Therefore, the heat exchange medium can enter each connected vertical disk 1 through the rotation center of the vertical disk 1. At the same time, the flow of the heat exchange medium will not change its position with the rotation of the vertical disk 1, which helps the heat exchange medium to be introduced inside the vertical disk 1. The cooling pipes 21 are all arranged inside the vertical disk 1, and the cooling pipes 21 are of a fixed structure and will not rotate with the rotation of the vertical disk 1 either.

[0084] Reference Figure 1 and Figure 2 , when the heat exchange medium enters the vertical disk 1, the high-calorie heat exchange medium will enter the inlet pipe and then enter the vertical disk 1 adjacent to the rotary joint 2. Then, after the heat exchange medium fills this vertical disk 1, it will enter the subsequent vertical disk 1 from the connection between adjacent vertical disks 1, and so on. The heat exchange medium will gradually fill all the vertical disks 1. Since the vertical disks 1 are vertically arranged, the heat exchange medium diffuses at a position close to the center of the vertical disk 1, and the temperature of the heat exchange medium here is relatively uniform. The higher-calorie heat exchange medium will rise to the upper end of the vertical disk 1, and the lower-calorie heat exchange medium will sink to the lower end of the vertical disk 1. Therefore, setting the connection position of the vertical disk 1 at a position close to the middle is more helpful for controlling the heating uniformity of the vertical disk 1. Further, by using one rotary joint 2 and connecting the vertical disks 1 at a position close to the middle, the heat exchange medium can heat multiple vertical disks 1 more uniformly. Further, making the vertical disks 1 have a relatively uniform temperature can enable multiple vertical disks 1 to have the same or similar processing efficiency when drying wet materials. It helps to control the feeding of the wet materials onto the vertical disks 1.

[0085] It should be noted here that when the heat exchange medium flows in the vertical disk 1, there will be heat loss of the heat exchange medium. Therefore, the temperatures of the heat exchange medium in different vertical disks 1 will also vary. In this application, by setting the connection method of the vertical disks 1 and the layout of the inlet pipe and the outlet pipe, the temperature difference between the vertical disks 1 is reduced. Due to the temperature difference between the vertical disks 1, the efficiency of heating and treating the wet material will be different. Therefore, in order to balance the processing speed between the vertical disks 1 and the wet material. In this application, either by increasing the heat of the heat exchange medium, the vertical disk 1 at the end position can still complete the drying process of the wet material within the rotation period. Similarly, the adhesion amount of the wet material on each vertical disk 1 can also be controlled, so that the wet material on the vertical disk 1 can complete the drying process within one rotation period.

[0086] Compared with connecting the vertical disks 1 at the edge position, connecting at the edge position will not only make the temperature inside the vertical disk 1 inconsistent, but also the rotating vertical disk 1 will drive the heat exchange medium at its internal edge position to flow, making the flow of the heat exchange medium in different vertical disks 1 more difficult to control. Therefore, in this application, the vertical disks 1 are vertically arranged and connected at the central position, so that the rotary joints 2 between the multiple vertical disks 1 can flow at a position where the heat exchange medium is relatively uniform and the change range is small, reducing the temperature difference of the heat exchange medium inside different vertical disks 1. And the vertically arranged vertical disks 1 can also, under the action of gravity, make the heat exchange medium with high temperature and high heat rise, and the heat exchange medium with low temperature and low heat sink, improving the uniformity of the heat exchange medium at the middle position.

[0087] Reference Figure 1 and Figure 2 , the feeding system is used to convey the wet material onto the vertical disk 1; the feeding system includes feeding pipes 12 respectively arranged on both sides of the vertical disk 1;

[0088] The feeding pipe 12 is of a tubular structure. The wet material is located in the feeding pipe 12, and the wet material can flow in the feeding pipe 12.

[0089] In a specific embodiment, the feeding pipe 12 is composed of a combination of multiple tubular conveying pipes. The end of each conveying pipe abuts against the vertical disk 1, and the conveying pipe is used to convey and attach the wet material onto the vertical disk 1.

[0090] Preferably, nozzles are arranged on the feeding pipe; the nozzles face the vertical disk, and the nozzles can spray the wet material onto the vertical disk.

[0091] In a specific embodiment, nozzles (not shown in the figure) are arranged on the feeding pipe 12 to spray the wet material onto the vertical disk 1.

[0092] In another specific embodiment, the cloth pipe 12 has a pipe structure of a cloth pipe 12, and a plurality of cloth holes are formed in the cloth pipe 12. The wet material flows in the cloth pipe 12 and then discharges from the cloth pipe 12 through each cloth hole. The cloth holes are in contact with the vertical disk 1. After the wet material comes out from the cloth holes, it will directly adhere to the vertical disk 1, and then the vertical disk 1 will dry the wet material.

[0093] Reference Figure 1 and Figure 2 , preferably, the scraping system is used to scrape the dry material on the vertical disk 1; the scraping system includes a scraper 11 in contact with the vertical disk 1.

[0094] Reference Figure 1 and Figure 2 , the scraper 11 is in contact with the upper surface of the vertical disk 1. The cloth pipe 12 transports the wet material to the vertical disk 1, and then the scraper 11 is used to scrape the dry material on the vertical disk 1.

[0095] The scraper 11 is arranged adjacent to the cloth pipe 12. When the vertical disk 1 rotates, the cloth pipe 12 spreads the wet material on the vertical disk 1. As the vertical disk 1 rotates, the wet material is dried to obtain dry material, and then it is scraped by the scraper 11. Therefore, in the rotation direction of the vertical disk 1, the scraper 11 is located at the rear position of the cloth pipe 12.

[0096] The scraper 11 is used to scrape and recover the material on the vertical disk 1. The scraper 11 is located on the vertical disk 1 and is in contact with the surface of the vertical disk 1. When the vertical disk 1 rotates, the scraper 11 can scrape the material on the vertical disk 1. Since the wet material will adhere to the vertical disk 1. Therefore, when the wet material dries, the dry material will adhere to the upper surface of the vertical disk 1. The scraper 11 in contact with the surface of the vertical disk 1 is used for collection, reducing the residue of the dry material on the vertical disk 1 and improving the collection effect of the dry material.

[0097] Preferably, both ends of the scraper 11 are respectively located at a position close to the center of the vertical disk 1 and a position close to the edge of the vertical disk 1;

[0098] Reference Figure 1 and Figure 2 , the scraper 11 is used to collect the dry material on the vertical disk 1. When the vertical disk 1 rotates, it will drive the dry material to rotate continuously. Therefore, when the scraper 11 covers the radial direction of the vertical disk 1, the dry material can be completely collected by the scraper 11.

[0099] Preferably, the scraper 11 is arranged along the radial direction of the vertical disk 1. And the length of the scraper 11 is adapted to the radius of the vertical disk 1.

[0100] Since the center position of the vertical disk 1 is a rotary joint 2, arranging the scraper 11 along the radial direction of the vertical disk 1 can reduce the length of the scraper 11. At the same time, it can also reduce the interference between the scraper 11 and the heat source pipe assembly, improving the safety of using the vertical disk 1.

[0101] Reference Figure 1 and Figure 2 , a pressing wheel is arranged on the vertical disk 1, the pressing wheel is arranged opposite to the scraper 11, and the pressing wheel is located behind the scraper 11;

[0102] In this application, it is defined with the movement direction of the wet material as the standard. When the wet material and the dry material move forward, they first contact the pressing wheel, and then the wet material will contact the scraper 11. Therefore, the scraper 11 is located in front of the pressing wheel.

[0103] Reference Figure 1 and Figure 2 , the pressing wheel is used to press and fix the dry material, reducing the movement of the dry material on the vertical disk 1 when the scraper 11 scrapes the dry material; enabling the scraper 11 to scrape the dry material more cleanly; reducing the residue of the dry material. Moreover, the pressing wheel can also prevent the dry material from slipping on the vertical disk 1, thereby reducing the occurrence of the dry material pushing and piling up the wet material, improving the drying effect of the vertical disk 1 on the wet material.

[0104] Reference Figure 1 and Figure 2 , preferably, a threshing roller is arranged on the vertical disk 1, and the threshing roller is arranged along the radial direction of the vertical disk 1;

[0105] More preferably, the threshing roller can rotate along its own axis;

[0106] More preferably, pointed spikes are arranged on the threshing roller, the tips of the pointed spikes are close to the vertical disk 1, and the pointed spikes can penetrate into the wet material.

[0107] After the wet material adheres to the vertical disk 1, the vertical disk 1 will heat the wet material, and the moisture on the outer surface of the wet material will evaporate from the wet material first. The wet material at the surface position will agglomerate into dry material, which will clog the evaporation of the moisture in the internal wet material, resulting in incomplete drying of the wet material. The pointed spikes on the threshing roller can pierce through the agglomerated dry material on the surface of the wet material, enabling the liquid in the internal wet material to evaporate from the pierced holes, thereby enabling the internal dry material to be fully dried, reducing the content of the liquid component in the dry material, and improving the drying effect on the wet material.

[0108] Since the wet material is driven by the vertical disk 1 to rotate, the threshing roller is also set to a rotating structure, and a plurality of spikes are provided on the surface of the threshing roller. The spikes can successively pierce the surface of the wet material, increasing the permeability of the wet material after passing through the threshing roller, thereby enhancing the drying effect on the wet material and breaking the large pieces of the material into small pieces to prevent material accumulation.

[0109] Reference Figure 1 and Figure 2 , the dryer includes a material crushing system, and the material crushing system includes a crushing bin 3 and a crushing shaft 4 located below the scraper 11; the scraper 11 can scrape the dry material on the vertical disk 1 into the crushing bin 3, and the crushing shaft 4 can crush the dry material.

[0110] The crushing bin 3 is arranged below the vertical disk 1. After the scraper 11 scrapes the dry material from the vertical disk 1, the dry material will fall into the crushing bin 3 under the action of gravity; the crushing bin 3 collects the dry material.

[0111] The dry material obtained by drying the wet material on the vertical disk 1 will be caked, so the dry material scraped from the vertical disk 1 will present a plate-like or sheet-like structure. After the caked dry material falls into the crushing bin 3, the crushing shaft 4 will rotate accordingly to crush the caked dry material, thereby breaking the dry material into particles or small-sized fragments, making the dry material easier to transport.

[0112] The crushing bin 3 collects and accommodates the dry material in the crushing bin 3, and then uses the crushing shaft 4 to crush the dry material, which can not only reduce the leakage caused by the splashing of the dry material during crushing, but also increase the quantity of the dry material that the crushing shaft 4 can crush, improving the working efficiency of the crushing shaft 4.

[0113] Reference Figure 1 and Figure 3 , the crushing shaft 4 can hammer or impact the dry material. After the caked sheet-like dry material enters the crushing bin 3, it will be broken into particles or small-sized fragments by the crushing shaft 4. At the same time, the screen 5 can intercept and screen the caked large-sized dry material, so that the large-sized dry material can only pass through the screen 5 after being broken into small-sized by the crushing shaft 4. Further reducing the leakage of the caked dry material from the gap of the crushing shaft 4. Improving the crushing effect and efficiency of the crushing shaft 4 and the crushing bin 3 on the dry material.

[0114] The crushing shaft 4 can rotate, and a plurality of crushing columns are arranged on the crushing shaft 4, and the crushing columns extend in a direction away from the crushing shaft 4;

[0115] In a specific embodiment, the crushing column is perpendicular to the crushing shaft 4.

[0116] In another specific embodiment, the crushing column is arranged crosswise with the crushing shaft 4.

[0117] Reference Figure 1 and Figure 3 , the crushing shaft 4 can rotate around its own axis, and the crushing shaft 4 can drive the crushing column to perform a rotational movement centered on the crushing shaft 4. When the crushing column rotates, it will impact the dry material in contact with it, thereby realizing the crushing of the dry material. The dry material is crushed into a small particle size state.

[0118] In the present application, the crushing column extends in a direction away from the crushing shaft 4. The number and angle of the crushing columns can be selected by those skilled in the art according to specific circumstances, so that the crushing columns can impact and crush the agglomerated dry material, and avoid blockage of the dry material due to excessive number of crushing columns.

[0119] Preferably, the crushing shaft 4 is arranged at a position close to the middle of the crushing chamber 3, and the end of the crushing column away from the crushing shaft 4 extends close to the inner wall of the crushing chamber 3.

[0120] Reference Figure 1 and Figure 3 , the dry material is scraped off from the vertical plate 1 and into the crushing chamber 3. In order to enable the crushing column to more thoroughly crush the dry material, therefore, the crushing shaft 4 is arranged at the middle position of the crushing chamber 3, and the crushing shaft 4 centered on the crushing shaft 4 extends from the central position of the crushing chamber 3 to the inner edge position, so that when the crushing shaft 4 and the crushing column rotate, they can cover the entire cross-section of the crushing chamber 3. Therefore, the crushing shaft 4 and the crushing column can crush all the dry material entering the crushing chamber 3, thereby reducing the possibility of large particle size dry material existing in the crushing chamber 3. Improve the crushing efficiency of the dry material and reduce the possibility of blockage of the dry material in the crushing chamber 3.

[0121] The crushing shaft 4 is located inside the crushing chamber 3, and a screen 5 is arranged below the crushing shaft 4. The screen 5 is provided with screen holes for avoiding the crushing shaft 4; the crushing column can enter the screen holes.

[0122] Reference Figure 1 and Figure 3 , the screen holes are formed as rectangular holes, and the positions where the screen holes are formed correspond to the positions of the crushing columns. When the crushing shaft 4 rotates, the crushing column can enter the screen holes. Therefore, a shear structure is formed between the crushing column and the screen 5. When the dry material is intercepted by the screen 5, the crushing column will impact the intercepted dry material, thereby crushing the dry material into small particle sizes, and then it will pass through the screen 5.

[0123] Reference Figure 1 and Figure 3, in the present application, the screen 5 has a V-shaped cross-sectional structure, and the screen 5 is located below the crushing shaft 4. The V-shaped screen 5 can effectively reduce the spacing from the crushing column, thereby reducing the residue of materials on the screen 5. In addition, the V-shaped structure with a lower middle and higher sides helps to reduce the residue of dry materials on the screen 5. When the dry materials fall onto the screen 5, the dry materials will, under the action of gravity, gather at the position near the middle of the screen 5, and then the dry materials will be impacted and crushed by the crushing column and the crushing shaft 4, and then will pass through the screen 5. The possibility of accumulation or residue of dry materials on the screen 5 and in the crushing chamber 3 is reduced.

[0124] The dryer includes a housing 9 system. The drying system is arranged inside the housing 9 system. The dryer further includes a conveying system for conveying the dry materials on the drying system out of the housing 9 system.

[0125] Reference Figure 1 and Figure 3 , the housing 9 system is arranged outside the drying system, and the housing 9 system protects the drying system. In addition, the housing 9 system is of a closed structure, and the drying system is arranged in the internal hollow chamber of the housing 9 system. On the one hand, the housing 9 system can isolate the drying system, thereby reducing the influence of the external environment on the drying system, enabling the drying system to more stably dry the wet materials. At the same time, both the wet materials and the dry materials are inside the housing 9 system, which is also convenient for centralized treatment of the wet materials and the dry materials. The liquid evaporated from the wet materials can also be collected through the housing 9 system, enabling the dryer to process more types of wet materials. The practicability of the dryer is improved. On the other hand, the housing 9 system can also wrap the drying system, causing the dry materials to gather inside the housing 9 system, reducing the loss of dry materials during drying and collection. And the wet materials are also located inside the housing 9 system, reducing the waste caused by the wet materials being splashed out due to the rotation of the vertical disk 1. On the other hand, the housing 9 system also has a heat preservation effect. The heat on the vertical disk 1 will be retained in the housing 9 system, keeping the temperature in the housing 9 system at a relatively high temperature. Therefore, when the wet materials adhere to the vertical disk 1, the temperature in the housing 9 system will also heat and dry the wet materials simultaneously, further improving the drying efficiency of the dryer.

[0126] Reference Figure 1 and Figure 3 , when the drying system finishes drying the wet materials, it is necessary to convey the obtained dry materials out of the housing 9 system. In order to reduce the influence of the external environment on the inside of the housing 9 system when the dry materials are output, therefore, a conveying system is used to convey the dry materials out of the housing 9 system. Compared with directly discharging the dry materials through an opening on the housing 9 system, the conveying system can isolate the drying system.

[0127] Preferably, the conveying system can convey dry materials out of the housing 9 system in a sealed environment;

[0128] More preferably, the conveying system can convey dry materials out of the housing 9 system in a vacuum environment;

[0129] More preferably, the interior of the housing 9 system is a vacuum environment.

[0130] Reference Figure 1 and Figure 2 , in the present application, the housing 9 system is a sealed structure. Therefore, the housing 9 system isolates its internal drying system from the outside world, reducing the interference of substances such as gas in the external environment on the inside of the housing 9 system. The interior of the housing 9 system is in a vacuum state. Here, the vacuum is not a vacuum in the physical sense, but meets the standard requirements of the vacuum processing technology in industry. Therefore, during use, the air inside the housing 9 system is evacuated to a vacuum state, and then the wet materials are conveyed into the housing 9 system, so that only wet materials, dry materials, and the liquid components evaporated from the wet materials remain inside the housing 9 system. Therefore, after the dryer in the present application dries the wet materials, the dry material cost and liquid components in the wet materials are separated, and the separated liquid cost has extremely high purity. The housing 9 system in a vacuum environment makes the obtained dry materials have extremely high purity, and the separated liquid components are also extremely pure.

[0131] The conveying system is also a sealed structure. Therefore, when conveying dry materials, the isolation between the dry materials and the external environment is still maintained, so that the obtained dry materials have sufficient purity.

[0132] Reference Figure 1 and Figure 2 , the conveying system includes a screw bin 6. The scraping system can scrape dry materials into the screw bin. The screw bin 6 is arranged inside the housing 9 system, and a screw shaft is arranged inside the screw bin 6;

[0133] The screw bin 6 is arranged below the crushing bin, and the screw bin 6 is communicated with the crushing bin;

[0134] Preferably, the screw bin 6 and the crushing bin are integrally formed;

[0135] More preferably, the cross-sectional size of the screw bin 6 increases from top to bottom;

[0136] More preferably, the upper end of the screw bin 6 is in a shape adapted to the crushing bin, and the lower end of the screw bin 6 is in a shape adapted to the screw shaft;

[0137] More preferably, the screw bin 6 has a structure with a round bottom and a square top.

[0138] Reference Figure 1 andFigure 2 The crushing bin 3 collects the dry materials, and then the auger bin 6 conveys the dry materials. After the dry materials fall into the crushing bin 3, the dry materials will be crushed by the crushing bin 3 to make the dry materials into a small particle size structure. Therefore, in order to enable the dry materials to fully enter the crushing bin 3, the crushing bin 3 is made into a large-size structure to reduce the possibility of dry material leakage. The auger bin 6 is used to convey the collected small particle size dry materials, so the size of the auger bin 6 is a smaller size.

[0139] Furthermore, in order to reduce the residue of dry materials in the crushing bin 3 and the auger bin 6, the crushing bin 3 and the auger bin 6 are integrally formed to reduce the gap between the crushing bin 3 and the auger bin 6. So that the dry materials can smoothly enter the auger bin 6 after being crushed in the crushing bin 3. The structure of the auger bin 6 is a shape that fits the crushing bin 3 in the upper part and a shape that fits the auger shaft in the lower part. That is, the cross-section of the auger bin 6 is a structure with a square shape on the upper part and a circular shape on the lower part. The square structure at the upper position fits the cuboid structure of the crushing bin 3, and the circular cross-section at the lower part fits the auger shaft, and the outer edge of the auger shaft is in close contact with the inner wall of the auger bin 6.

[0140] Reference Figure 1 and Figure 2 In this application, multiple vertical disks 1 are arranged side by side, and the drying treatment of wet materials is carried out on both side surfaces at the two ends of each vertical disk 1. Therefore, dry materials will be generated on both sides of the vertical disk 1. The dry materials scraped off by the scraper 11 will be collected by the crushing bin 3. Therefore, a crushing bin 3 is arranged between two adjacent vertical disks 1 so that the dry materials on the two adjacent end faces of the two vertical disks 1 can be simultaneously scraped into one crushing bin 3, thereby reducing the number of crushing bins 3. The equipment cost of the dryer is reduced. Similarly, the auger bin 6 connected to the crushing bin 3 is also arranged in the same way.

[0141] Preferably, a sealed bin 7 is connected to the output end of the auger bin 6; the sealed bin 7 is arranged outside the housing 9 system;

[0142] More preferably, a sealed auger is arranged in the sealed bin 7. The inside of the sealed bin 7 is a cylindrical chamber, and the outer diameter of the sealed auger is adapted to the inner diameter of the sealed bin 7.

[0143] The auger bin 6 and the sealed auger are used to convey the dry materials. The dry materials in the housing 9 system will be collected in the crushing bin 3, and then the crushed dry materials will enter the auger bin 6. The auger bin 6 collects and transports the dry materials. The auger shaft is located in the auger bin 6. On the one hand, the rotation of the auger shaft can convey the dry materials in the auger bin 6, and the dry materials will flow in the auger bin 6 under the operation of the auger shaft. On the other hand, the auger shaft can also seal the auger bin 6. Therefore, the possibility of gas entering the housing 9 system from the auger bin 6 is reduced.

[0144] Reference Figure 1 and Figure 2 , the sealed bin 7 is a chamber structure in a sealed state. The sealed bin 7 is connected to the auger bin 6, and the materials in the auger bin 6 will enter the sealed bin 7. At the same time, the sealed bin 7 can also seal the outlet end of the auger bin 6. Thus, the inside of the housing 9 system and the inside of the auger bin 6 are in a completely sealed state.

[0145] The sealed auger in the sealed bin 7 can seal the sealed bin 7. The outer surface of the sealed auger fits with the inner surface of the sealed bin 7. Therefore, the space in the sealed bin 7 is sealed. After the sealed auger is filled with dry materials, the dry materials will fill the gaps between the augers, making the sealed auger form a solid cylindrical structure, filling the inside of the sealed bin 7 and achieving the sealing effect of the sealed bin 7.

[0146] At the same time, other sealing structures can also be used for the sealed bin 7, such as one-way valves or sealing valves, etc., as long as the sealing structure of the sealed bin 7 can be achieved.

[0147] Reference Figure 1 and Figure 2 , a connecting pipe 8 is provided between the sealed bin 7 and the auger bin 6. The connecting pipe 8 is fixedly connected to the output end of the auger bin 6, and the connecting pipe 8 is detachably connected to the sealed bin 7;

[0148] Preferably, the connecting pipe 8 penetrates through the housing 9 system;

[0149] The auger bin 6 is arranged inside the housing 9 system, and the sealed bin 7 is arranged outside the housing 9 system. Therefore, the connecting pipe 8 is used to connect the auger bin 6 and the sealed bin 7.

[0150] The connecting pipe 8 penetrates through the housing 9 system, the connecting pipe 8 is fixedly connected to the housing 9 system, and a seal is maintained between the connecting pipe 8 and the housing 9 system.

[0151] The connecting pipe 8 is respectively connected to the auger bin 6 and the sealed bin 7, and a seal is maintained between the connecting pipe 8 and the auger bin 6 and the sealed bin 7 respectively.

[0152] Reference Figure 1 and Figure 2 , further preferably, two or more than three auger bins 6 are provided, and one sealed bin 7 is provided. Each auger bin 6 is connected to a connecting pipe 8, and all the connecting pipes 8 are communicated with the sealed bin 7.

[0153] The number of auger bins 6 is equal to the number of crushing bins 3, and the position of the auger bin 6 is adapted to be below the crushing bin 3. A connecting pipe 8 is respectively connected to each auger bin 6. One sealed bin 7 is provided, and all the connecting pipes 8 are simultaneously communicated with the sealed bin 7.

[0154] Therefore, when the dryer is in use, the dry material falls from the vertical plate 1 and enters the crushing bin 3. After being crushed, the dry material enters the auger bin 6 for transportation, and then the dry material is transported out of the housing 9 system to the sealed bin 7. The sealed bin 7 can not only transport the material but also seal the housing 9 system, keeping the dry material in a state isolated from the outside world.

[0155] Reference Figure 1 and Figure 2 , the connecting pipe 8 is detachably connected to the sealed bin 7, which is convenient for maintenance when the sealed bin 7 or the auger bin 6 is blocked.

[0156] When the auger bin 6 is blocked, the sealed bin 7 can be opened, and the auger bin 6 can be repaired and inspected through the connecting pipe 8. Since the space above the auger bin 6 is large and it is connected to the crushing bin 3, the blockage and other faults of the auger bin 6 can also be inspected through the housing 9 system and the crushing bin 3.

[0157] Since the sealed bin 7 is connected to multiple auger bins 6, and all the auger bins 6 are connected to the sealed bin 7. Therefore, the sealed bin 7 is more likely to be blocked compared to the auger bin 6. At the same time, compared to the open structure of the auger bin 6, it is even more difficult for the auger bin 6 to be blocked. Due to the sealing requirements in the sealed bin 7, the material is prone to accumulation, resulting in blockage and other faults.

[0158] When the sealed bin 7 is blocked, since the sealed bin 7 is located outside the housing 9 system, the sealed bin 7 can be directly removed from the connecting pipe for repair or replacement to solve the blockage and other faults, making the replacement and repair of the sealed bin 7 more convenient.

[0159] Reference Figure 1 , the dryer includes a drying system, a cloth scraping system, a material crushing system, and a transmission system. The wet material enters from the cloth pipe 12 of the cloth scraping system, and then the cloth pipes on both sides of the vertical plate will transport the material to the vertical plate 1 respectively. The nozzles provided on the cloth pipes can spray the wet material more evenly on the surface of the vertical plate. The wet material will adhere to both end faces of the vertical plate 1. The water vapor enters the hollow chamber of the vertical plate 1 through the inlet pipe via the rotary joint 2, heating the vertical plate 1 with the water vapor, and then the vertical plate 1 heats the wet material to evaporate and remove the moisture in the wet material. Then the dry material is scraped off the vertical plate 1 by the scraper 11. The dry material slides along the scraper 11 into the crushing bin 3. The crushing shaft 4 rotates continuously and impacts the dry material falling into the crushing bin 3, crushing the large particles of the dry material. The small particle material after crushing will pass through the screen 5, and the large particle material will be intercepted by the screen 5 and continue to be crushed by the crushing shaft 4.

[0160] The dry material after passing through the sieve 5 will enter the auger bin 6 at the lower end and be conveyed by the auger shaft in the auger bin 6, and then conveyed out through the connecting pipe 8 penetrating the outer shell 9. The material will enter the sealed bin 7 outside the outer shell 9, and then the conveying shaft is used to transport the material. When the conveying auger is blocked or damaged during use, the conveying auger can be directly disassembled from the connecting pipe 8, replaced with a new conveying auger and installed, and then it can be directly used. This greatly shortens the time affected by auger blockage or failure.

After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
