The subsequent description of the specification is a preferred embodiment of the present application, but the description is based on the general principles 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 attached claims.

[0055] refer to Figure 1 and Figure 2 , the present application provides a dryer, which includes a shell system, a material system and a drying system;

[0056] The drying system and the material system are arranged inside the shell system;

[0057] The material system is used for the input and output of materials.

[0058] refer to Figure 1 and Figure 2 The drying system is used to dry the wet materials. The wet materials can pass through the outer shell system into the internal drying system, and then the wet materials are dried by the drying system to obtain dry materials, and the dry materials are discharged from the outer shell system.

[0059] The material system is used to transport the wet material to the drying system, and then the dry material obtained after the wet material is dried by the drying system is transported out of the shell system by the material system.

[0060] refer to Figure 1 and Figure 2 , wet materials include solid materials and liquid materials. Wet materials can be in liquid form, granular form or solid form.

[0061] refer to Figure 1 and Figure 2 , the drying system comprises one or more rotatable drying discs 2;

[0062] Specifically, the number of drying plates 2 is: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50.

[0063] refer to Figure 1 and Figure 2 The drying plate 2 is used to dry the material. When the wet material is spread on the drying plate 2, the drying plate 2 dries the wet material, thereby drying the wet material into dry material.

[0064] refer to Figure 1 and Figure 2 The drying plate 2 is used for placing materials, so the drying plate 2 is arranged horizontally. When the drying plate 2 rotates, the materials on the drying plate 2 will be flattened onto the drying plate 2 under the action of centrifugal force.

[0065] The drying plate 2 can be fixed, rotatable, vibrating, swinging or shaking. Preferably, the drying plate 2 is rotatable.

[0066] refer to Figure 1 and Figure 2 When the wet material is conveyed to the drying plate 2, the drying plate 2 will rotate, and the material on the drying plate 2 will be flattened onto the drying plate 2 under the action of centrifugal force. This will improve the drying effect and speed of the drying plate 2 on the wet material and improve the drying efficiency.

[0067] At the same time, since the drying plate 2 is used for drying, the wet material or liquid material can be spread on the drying plate 2, thereby drying the wet material or liquid material. More importantly, the drying plate 2 can rotate, so that the material on the drying plate 2 can be spread on the drying plate 2 more evenly under the action of centrifugal force.

[0068] refer to Figure 2 , the drying system further comprises a heat source pipe assembly, and the heat source pipe assembly is arranged through the drying plate 2;

[0069] refer to Figure 2 The heat source tube assembly is connected to the drying tray 2 , and the heat source tube assembly can heat the drying tray 2 .

[0070] When the drying plate 2 dries the wet material, it can be either heating drying, ventilation drying, or other drying methods such as ventilation and heating. Heating drying is preferred.

[0071] refer to Figure 2The heat source pipe assembly can provide heat source to the drying plate 2, heat the drying plate 2, and then the drying plate 2 dries the moisture in the wet material. The heat source of the heat source pipe assembly can be water, water vapor, oil, thermal oil or electric heating for heating treatment.

[0072] refer to Figure 2 There are multiple drying trays 2, and each drying tray 2 is connected to the heat source pipe assembly. In order to facilitate the connection between the heat source pipe assembly and the drying tray 2, multiple drying trays 2 are stacked on each other, and the heat source pipe assembly can penetrate the multiple drying trays 2 in the vertical direction while realizing the connection between the heat source pipe assembly and the drying tray 2. The heat source pipe assembly can provide heat to the drying tray 2.

[0073] On the other hand, the heat source pipe assembly passes through the center of the drying tray 2, so when the heat source pipe assembly heats the drying tray 2, the heat can diffuse from the center of the drying tray 2 to the edges of the drying tray 2, so that the wet materials on the drying tray 2 are heated more evenly, thereby improving the drying efficiency of the drying tray 2.

[0074] refer to Figure 2 Moreover, the way in which the heat source tube assembly penetrates and connects the drying tray 2 makes it more convenient to connect the heat source tube assembly and the drying tray 2. When more drying trays 2 are needed, drying trays 2 can be directly added to the heat source tube assembly by directly penetrating the added drying trays 2 to the heat source tube assembly. It is convenient to control the number of drying trays 2 heated by the heat source tube assembly.

[0075] refer to Figure 2 The heat source tube assembly includes an inner tube 31 and an outer tube 32 , the inner tube 31 is arranged inside the outer tube 32 , and the lower end of the inner tube 31 is connected to the outer tube 32 .

[0076] refer to Figure 2 The heat source tube assembly is used to heat the drying plate 2. And the heat source tube assembly passes through the drying plate 2.

[0077] refer to Figure 2 In a specific embodiment, the heat source pipe assembly is heated by passing hot steam.

[0078] The outer tube 32 passes through the center of the drying tray 2 , and the outer tube 32 is directly connected to the drying tray 2 . Therefore, heat can be transferred to the drying tray 2 through the outer tube 32 .

[0079] The inner tube 31 is located inside the outer tube 32 , and the outer tube 32 communicates with the inner tube 31 at a position of a lower end in the vertical direction.

[0080] refer to Figure 2A heat exchange medium flows inside the heat source tube assembly. The heat exchange medium flows into the outer tube 32, flows into the lower end of the outer tube 32, then flows into the inner tube 31 from the lower end, and then flows out from the upper end of the inner tube 31, thereby realizing the flow of the heat exchange medium in the inner tube 31 and the outer tube 32, and transferring heat to the outer tube 32 and the drying plate 2 at the same time.

[0081] refer to Figure 2 The inner tube 31 and the outer tube 32 are used for the heat exchange medium to flow, and the inner tube 31 is arranged inside the outer tube 32, thereby reducing the volume of the heat exchange tube assembly, and also reducing the space for the heat exchange medium to flow, and at the same time can also increase the flow speed of the heat exchange medium. Improve the heating efficiency of the drying plate 2.

[0082] In a specific embodiment, the heat exchange medium is a liquid medium such as heat transfer oil or water.

[0083] In another specific embodiment, the heat exchange medium is a gas medium such as water vapor.

[0084] refer to Figure 2 The outer tube 32 is connected to the drying tray 2. In a specific embodiment, the drying tray 2 is a hollow structure, and the hollow chamber of the drying tray 2 is connected to the outer tube 32. Therefore, the heat exchange medium can enter the hollow chamber of the drying tray 2 from the outer tube 32, and then the heat exchange medium can directly heat the drying tray 2. The heating efficiency of the heat source tube assembly on the drying tray 2 is improved.

[0085] refer to Figure 1 and Figure 2 The heat source pipe assembly further includes a rotary joint 3, and the rotary joint 3 includes a first interface connected to the outer pipe 32 and a second interface connected to the inner pipe 31, and the first interface and the second interface are respectively sealed.

[0086] refer to Figure 2 The rotary joint 3 is arranged at the upper ends of the outer tube 32 and the inner tube 31 , and the rotary joint 3 is connected to the inner tube 31 and the outer tube 32 respectively.

[0087] refer to Figure 2 The first interface is connected to the outer tube 32, so the heat exchange medium can enter the outer tube 32 through the first interface, and then the heat exchange medium enters the inner tube 31 from the lower end of the outer tube 32, and then the heat exchange medium flows from the outer tube 32 to the second interface.

[0088] refer to Figure 2Since the inner tube 31 is arranged inside the outer tube 32, there is a first channel in the rotary joint 3, where the first interface is connected to the outer tube 32; and a second channel in which the second interface is connected to the inner tube 31. And the first channel and the second channel are not connected to each other. In this way, the heat exchange medium can enter from the first interface and then be discharged from the second interface. The heat exchange medium can smoothly enter the outer tube 32 and the drying plate 2, reducing the possibility of heat exchange medium leakage.

[0089] refer to Figure 2 The outer tube 32 and the inner tube 31 are sealed with the rotary joint 3 , and both the outer tube 32 and the inner tube 31 are rotatably connected with the rotary joint 3 .

[0090] refer to Figure 2 In one embodiment, the drying plate 2 is a rotating structure, the drying plate 2 abuts against the outer tube 32, and the drying plate 2 can rotate around the outer tube 32. The outer tube 32 and the inner tube 31 can be rotatably connected or fixedly connected to the rotary joint 3 respectively.

[0091] refer to Figure 2 In another specific embodiment, the drying disc 2 is a rotating structure, and the drying disc 2 is fixedly connected to the outer tube 32. The rotary joint 3 needs to be fed with a heat exchange medium, so the inner tube 31 and the outer tube 32 are both rotatably connected to the rotary joint 3. When the drying disc 2 rotates, the outer tube 32 and the inner tube 31 can be driven to rotate at the same time.

[0092] refer to Figure 2 In a specific embodiment, the outer tube 32 is connected to the inner tube 31 at the lower end, and there is no direct connection between the inner tube 31 and the outer tube 32. Therefore, when the drying plate 2 is a rotating structure, the outer tube 32 fixedly connected to the drying plate 2 is rotatably connected to the rotary joint 3. The inner tube 31 and the rotary joint 3 can be fixedly connected.

[0093] In another specific embodiment, the drying plate 2 is a non-rotating structure, and the drying plate 2 is fixedly connected to the outer tube 32. In this case, the outer tube 32 and the inner tube 31 can be rotatably connected or fixedly connected to the rotary joint 3 respectively.

[0094] refer to Figure 2 In one embodiment, the heat exchange medium is water vapor. The water vapor is transported from the rotary joint 3 to the outer tube 32, and at the same time enters the hollow chamber of the drying plate 2 through the outer tube 32, heating and drying the drying plate 2 and the wet materials thereon. After the water vapor heats the drying plate 2, it will condense into water and flow into the lower end of the outer tube 32. After the condensed water is collected at the lower ends of the inner tube 31 and the outer tube 32, the continuous introduction of water vapor in the outer tube 32 causes the air pressure to increase, and the condensed water will be squeezed into the inner tube 31, and finally discharged through the inner tube 31 and the rotary joint 3.

[0095] refer to Figure 1 and Figure 3 The material system includes a material distributing and scraping system; the material distributing and scraping system is located above the drying plate 2.

[0096] refer to Figure 1 and Figure 3 When the dryer dries the wet material, it is necessary to arrange the material on the drying plate 2. Therefore, a material distributing and scraping system is used to transport the wet material to the drying plate 2. Furthermore, in order to make the material on the drying plate 2 more evenly laid, a material distributing and scraping system is used to evenly arrange the wet material on the drying plate 2, so that the drying plate 2 can evenly heat the wet material and improve the drying efficiency of the wet material.

[0097] refer to Figure 1 and Figure 3 The material distribution and scraping system includes a material distribution pipe 41; the material distribution pipe 41 is arranged above the drying plate 2, and one or more material distribution holes are evenly opened on the material distribution pipe 41.

[0098] refer to Figure 1 and Figure 3 The wet material is located inside the distribution pipe 41. After the wet material is transported to the top of the drying plate 2 by the distribution pipe 41, the wet material will be discharged from the distribution pipe 41 through the distribution holes and fall onto the drying plate 2 located below the distribution pipe 41.

[0099] A plurality of cloth holes are provided on the cloth pipe 41; specifically, the number of the cloth holes is: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50.

[0100] The distribution holes on the distribution pipe 41 can be evenly or unevenly arranged; can be arranged in one row, multiple rows arranged side by side, or multiple rows arranged intermittently in the extending direction of the distribution pipe 41. In the art, any structure capable of conveying wet materials to the drying plate 2 through the distribution pipe 41 is the structural form claimed for protection in this application.

[0101] Preferably, in a specific embodiment, the material distribution holes are evenly opened on the material distribution tube 41 along the extension direction.

[0102] refer to Figure 1 and Figure 3When the wet material is discharged from the distribution holes, the multiple evenly arranged distribution holes will disperse the material onto the drying plate 2, thereby reducing the possibility of the wet material being accumulated on the drying plate 2.

[0103] refer to Figure 1 and Figure 3 The material distribution pipe 41 and the material distribution hole can transport the wet material to the designated position on the drying plate 2. Therefore, in actual use, the wet material can be transported to the appropriate position on the drying plate 2 according to the use situation, and further, the material distribution on the drying plate 2 is more uniform, thereby improving the drying effect of the drying plate 2 on the wet material.

[0104] refer to Figure 1 and Figure 3 The material distribution and scraping system includes a scraper, which abuts against the upper surface of the drying plate 2.

[0105] The material system uses a material distribution pipe 41 to transport the wet material to the drying plate 2, and then uses a scraper to scrape the dry material on the drying plate 2.

[0106] refer to Figure 1 and Figure 3 The scraper is arranged adjacent to the distribution pipe 41. When the drying plate 2 rotates, the distribution pipe 41 spreads the wet material onto the drying plate 2. As the drying plate 2 rotates, the wet material is dried to obtain dry material, which is then scraped by the scraper. Therefore, in the rotation direction of the drying plate 2, the scraper is located behind the distribution pipe 41.

[0107] refer to Figure 1 and Figure 3 , the scraper is used to scrape and recover the material on the drying plate 2. The scraper is located on the drying plate 2, and the scraper is in contact with the surface of the drying plate 2. When the drying plate 2 rotates, the scraper can scrape the material on the drying plate 2 onto the scraper. The scraper is used to collect the dry material obtained after the drying process on the drying plate 2. Since the wet material will be flattened on the drying plate 2 to speed up the drying speed. Therefore, when the wet material is dried, the dry material will adhere to the upper surface of the drying plate 2. Therefore, a scraper that is in contact with the surface of the drying plate 2 is used for collection. It can reduce the residue of dry material on the drying plate 2 and improve the collection effect of dry material.

[0108] refer to Figure 1 and Figure 3 Preferably, the two ends of the scraper are respectively located near the center of the drying plate 2 and near the edge of the drying plate 2;

[0109] refer to Figure 1 and Figure 3The scraper is used to collect the dry material on the drying plate 2. When the drying plate 2 rotates, the dry material will be driven to rotate continuously, so the scraper covers the radial direction of the drying plate 2, and the dry material can be completely collected by the scraper.

[0110] Preferably, the scraper is arranged along the radial direction of the drying disc 2 , and the length of the scraper is adapted to the radius of the drying disc 2 .

[0111] refer to Figure 1 and Figure 3 Since the heat source tube assembly is located at the center of the drying plate 2, the scraper is arranged radially along the drying plate 2, which can reduce the length of the scraper. At the same time, it can also reduce the interference between the scraper and the heat source tube assembly, thereby improving the safety of the dryer.

[0112] refer to Figure 1 and Figure 3 When the scraper deviates from the radial direction of the drying plate 2, the scraper will have an angular velocity deviation when collecting dry materials, which helps to collect dry materials evenly. However, the heat source pipe assembly located in the center is small in size, and the effect of the offset radial setting is small. Therefore, it is best to set the scraper in the radial direction.

[0113] Further preferably, the material distribution and scraping system includes a scraper bin 43, the scraper bin 43 is hollow, the scraper bin 43 is located above the scraper, and is connected to the scraper;

[0114] refer to Figure 1 and Figure 3 The scraper bin 43 is connected to the scraper and is located above the scraper. When the scraper scrapes the dry material on the drying plate 2, it will be transported to the scraper bin 43. The scraper bin 43 is used to store the dry material.

[0115] refer to Figure 1 and Figure 3 The scraper bin 43 is a rectangular parallelepiped structure, and the scraper is located at the lower end of the scraper bin 43. When the scraper scrapes the material on the drying plate 2, it will be transported to the scraper bin 43. At the same time, the scraper bin 43 is a sealed structure. When the dry material enters the scraper bin 43, it will be stored inside it, reducing the possibility of leakage of dry material from the scraper bin 43; thereby achieving the purpose of collecting dry materials.

[0116] refer to Figure 1 and Figure 3 In a specific embodiment, the scraper is located on one side below the scraper bin 43, and in the rotation direction of the drying plate 2, the scraper is located at the rear side of the scraper bin 43. When the dry material is scraped by the scraper, the dry material can enter the scraper bin 43 upward.

[0117] refer to Figure 1 and Figure 3The material distributing and scraping system further comprises a pressing wheel 42, which is radially arranged above the drying plate 2, and the length of the pressing wheel 42 is adapted to the radius of the drying plate 2;

[0118] The pressing wheel 42 is used to compact dry materials or wet materials. Preferably, the pressing wheel 42 compacts dry materials.

[0119] refer to Figure 1 and Figure 3 The pressing wheel 42 is used to compact the dry materials on the drying plate 2 , so the two ends of the pressing wheel 42 are respectively located at the center and edge of the drying plate 2 , so that the pressing wheel 42 can compact all the dry materials on the drying plate 2 .

[0120] refer to Figure 1 and Figure 3 The pressing wheel 42 can be arranged along the radial direction of the drying plate 2 or inclined to the radial direction of the drying plate 2, and both ends of the pressing wheel 42 can press all the dry materials on the drying plate 2. Preferably, the pressing wheel 42 is arranged along the radial direction of the drying plate 2, and the pressing wheel 42 is arranged parallel to the scraper.

[0121] refer to Figure 1 and Figure 3 The pressing wheel 42 presses the dry material onto the drying plate 2, and then the scraper can scrape the dry material into the scraper bin 43. Therefore, the pressing wheel 42 is arranged in parallel with the scraper, so that when the scraper scrapes the dry material, the squeezing force of the pressing plate on the dry material can reduce the slippage of the dry material, and the dry material can be directly collected by the scraper into the scraper bin 43.

[0122] refer to Figure 1 and Figure 3 After the wet material is dried on the drying plate 2, the dry material will adhere to the drying plate 2, and then the dry material will be collected by a scraper. However, there is a difference in the adhesion strength between the dry material and the drying plate 2, and the dry material changes from wet to dry, resulting in an interaction force inside, making it difficult for the scraper to scrape up the dry material. In fact, the scraper will block the rotation of the dry material, causing the dry material to slide on the drying plate 2, which will affect the drying of the wet material behind the dry material. Therefore, a pressing wheel 42 is used to press the dry material onto the drying plate 2. When the scraper scrapes the dry material, the pressing wheel 42 can reduce the possibility of the dry material sliding on the drying plate 2.

[0123] refer to Figure 1 and Figure 3 , further preferably, the pressure wheel 42 is arranged inside or outside the scraper bin 43, preferably the pressure wheel 42 is arranged inside the scraper;

Therefore, the pressing wheel 42 is arranged in front of the scraper, that is, the dry material is first pressed by the pressing wheel 42 and then scraped by the scraper.

[0125] refer to Figure 1 and Figure 3 When the pressing wheel 42 is arranged inside the scraper bin 43, even if the dry materials collected by the scraper inside the scraper bin 43 fall, they can still be pressed again by the pressing wheel 42 onto the drying plate 2 for collection. At the same time, the scraper bin 43 can also protect the pressing wheel 42, reducing the possibility of damage to the pressing wheel 42. And the pressing wheel 42 can be fixed on the side wall of the scraper bin 43, which facilitates the installation and fixing of the pressing wheel 42.

[0126] refer to Figure 1 and Figure 3 When the pressing wheel 42 is arranged outside the scraper bin 43, when the pressing wheel 42 is replaced, repaired or inspected, it can be directly checked and repaired from the outside of the dryer, making the replacement and maintenance inspection of the pressing wheel 42 more convenient.

In this case, two or more scrapers and scraper bins 43 and a pressing wheel 42 can be used to collect the dry material, thereby reducing the residual dry material on the drying plate 2.

[0132] Similarly, the distribution pipe 41 can increase the amount of wet material added to the drying plate 2, and a plurality of distribution pipes 41 can make the wet material more evenly distributed on the drying plate 2.
