Description

Technical Field

[0001] This utility model belongs to the field of drying technology, and in particular relates to a vertical dryer. Background Technology

[0002] A dryer is a device used to quickly remove moisture from materials and is widely used in industrial production. In a vertical dryer, materials are fed in from the top and fall to the bottom for discharge. During the fall, hot air generated by a side fan blows onto the materials, thus drying them. However, during the fall, materials closer to the inside are easily blocked by materials on the outside and receive less hot air, resulting in poor drying effect. This paper proposes a vertical dryer that can change the layered structure of the materials. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a vertical dryer that solves the above problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a vertical dryer, comprising a flared tube with openings at both the top and bottom, the flared tube being coaxially and fixedly disposed within a cylinder, a frustum being coaxially disposed below the flared tube, the area of ​​the upper surface of the frustum being larger than the area of ​​the lower surface of the flared tube, and multiple vertical plates being symmetrically and fixedly connected to the outer wall of the frustum, the frustum being rotatably disposed within the cylinder, and a conical head being coaxially and fixedly connected to the upper surface of the frustum.

[0005] Beneficial effects

[0006] This utility model provides a vertical dryer, which has the following advantages compared with the prior art:

[0007] 1. When the material is poured into the flared pipe, it falls vertically through the opening at the lower end of the flared pipe. Since the opening area at the lower end of the flared pipe is smaller than the area at the lower end of the cone, the material can fall onto the side wall of the cone and begin to slide along it, gradually sliding onto the platform. At this point, the user can rotate the platform at high speed. Since multiple vertical plates are fixedly connected to the outer wall of the platform, the material can be positioned between two adjacent vertical plates as it slides along the outer wall of the platform. This limits the material's position, allowing it to slide down the platform while rotating at high speed. This process effectively changes the material's position and layering structure, allowing the material on the inner side to be moved to the outer side. This prevents the inner material from being blocked by the outer material and thus not receiving sufficient hot air. Simultaneously, the high-speed rotation of the platform causes the material to detach from it under centrifugal force and impact the inner wall of the cylinder, further altering its layering structure and evenly dispersing the material for uniform heating.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0014] Please see Figures 1-3 This invention provides an embodiment of a vertical dryer, comprising a flared tube 201 with openings at both ends. The flared tube 201 is coaxially and fixedly disposed within a cylinder 101, and the area of ​​the upper end face of the flared tube 201 is larger than the area of ​​its lower end face. A frustum 202 is coaxially disposed below the flared tube 201, the area of ​​the upper end face of the frustum 202 is smaller than the area of ​​its lower end face, and the area of ​​the upper end face of the frustum 202 is larger than the area of ​​the lower end face of the flared tube 201. Multiple vertical plates are symmetrically and fixedly connected to the outer wall of the frustum 202. 203, the frustum 202 is rotatably set inside the cylinder 101; the user pours the material to be dried into the flared tube 201 in batches for drying, and during the feeding process, the user should always observe the material in the flared tube 201 to ensure that the material is always a certain distance from its upper end to avoid material overflow. After the dried material is discharged from the lower side of the cylinder 101, the user should use relevant humidity detection equipment to detect the humidity of the material. If the humidity of the material is still not up to standard, the user should put the material back into the flared tube 201 for drying until the humidity of the material reaches the standard.

[0015] In the above embodiment, when the material is poured into the flared tube 201, it falls vertically through the opening at the lower end of the flared tube 201. Since the opening area at the lower end of the flared tube 201 is smaller than the area at the lower end of the conical head 204, the material can fall onto the side wall of the conical head 204 and begin to slide along the side wall, gradually sliding onto the frustum 202. At this point, the user can rotate the frustum 202 at high speed. Since multiple vertical plates 203 are fixedly connected to the outer wall of the frustum 202, the material can slide between two adjacent vertical plates 203 while sliding on the outer wall of the frustum 202. In this process, the material is limited by the frustum 202, allowing it to slide down the frustum 202 while rotating at high speed. This effectively changes the position of the material and alters its layered structure, allowing the material on the inner side to be moved to the outer side. This prevents the inner material from being blocked by the outer material and thus from being unable to receive hot air effectively. At the same time, as the frustum 202 rotates at high speed, the material on it can be detached from it under the action of centrifugal force and impact the inner wall of the cylinder 101, thereby further changing its layered structure, evenly dispersing the material and ensuring that the material is heated evenly.

[0016] In this design, the flared tube 201 and the frustum 202 allow the material to fall layer by layer and circle by circle from the flared tube 201 onto the frustum 202. As the frustum 202 rotates at high speed, the material's position constantly changes, achieving uniform distribution. Simultaneously, the material impacts the inner wall of the cylinder 101 under centrifugal force, further breaking down the original layered structure, resulting in more uniform heating and improved drying efficiency.

[0017] In some examples of this application, the flared tube 201 can be designed in different shapes, such as trapezoidal or conical, to accommodate different types of materials. The number of vertical plates 203 of the frustum 202 can be adjusted according to actual needs, such as 3, 5, or 7, to optimize material distribution and heating effect. Furthermore, the rotational speed of the frustum 202 can also be adjusted according to material characteristics and drying requirements, such as 60, 80, or 100 revolutions per minute.

[0018] Specifically, a conical head 204 is coaxially fixedly connected to the upper end face of the frustum 202, and the lower end face of the conical head 204 has the same area as the upper end face of the frustum 202. The upper end of the conical head 204 is located below the lower end of the flared tube 201.

[0019] Specifically, the conical head 204 is provided with a drive assembly for rotating the frustum 202 at high speed. The drive assembly includes a vertical rod 205. The lower end of the vertical rod 205 is coaxially fixedly connected to the upper end face of the conical head 204, and the vertical rod 205 is vertically arranged at the axis of the flared tube 201. The upper end of the vertical rod 205 is rotatably connected to the flared tube 201.

[0020] Specifically, a motor 208 is vertically fixed on the upper end face of the flared tube 201, and the output shaft of the motor 208 is fixedly connected to the upper end face of the vertical rod 205; the motor 208 should integrate a power supply for supplying power to it and a switch for controlling its start and stop.

[0021] In the above embodiment, the user starts the motor 208, which causes the vertical rod 205 fixedly connected to it to start rotating at high speed. At this time, the frustum 202 can start rotating inside the cylinder 101, thereby changing the layered structure of the material.

[0022] In some examples of this application, the design of the frustum 202 and the cone 204 enables the frustum 202 to rotate at high speed. When the cone 204 is mounted on the frustum 202, the lower end face of the cone 204 has the same area as the upper end face of the frustum 202, resulting in a large contact area and stable fixation. Power is transmitted to the cone 204 via a drive assembly (such as the vertical rod 205), thereby driving the frustum 202 to rotate at high speed, altering the layered structure of the material and improving drying efficiency. Furthermore, the use of the motor 208 further ensures the efficient operation of the frustum 202.

[0023] In some examples of this application, the drive component can be of various types, such as belt drive, gear drive, or direct mechanical connection. The motor 208 can be a DC motor or an AC motor, or a stepper motor or a servo motor. The power supply for the motor 208 can be battery powered or an external power supply, and the switch can be a manual switch or an automatic control switch.

[0024] Specifically, a stirring plate 303 is vertically installed inside the flared tube 201, and the two sides of the stirring plate 303 are attached to the inner wall of the flared tube 201. The stirring plate 303 is fixedly connected to the outer wall of the vertical rod 205. When the user starts the motor 208, the stirring plate 303 fixedly connected to the vertical rod 205 rotates synchronously. At this time, the material in the flared tube 201 can be stirred by the stirring plate 303, thereby accelerating the speed at which the material falls from the flared tube 201 and avoiding blockage.

[0025] Specifically, the flared tube 201 is provided with an adjustment component for controlling the material falling onto the frustum 202. The adjustment component includes a disc 209, which is coaxially fixedly connected to the opening at the lower end face of the flared tube 201. The disc 209 is symmetrically provided with fan-shaped through grooves 301, and a fan-shaped sealing plate 302 with the same cross-section as the fan-shaped through grooves 301 is horizontally provided below the disc 209.

[0026] Specifically, the upper end face of the fan-shaped sealing plate 302 is attached to the lower end face of the disc 209, and the fan-shaped sealing plate 302 is fixedly mounted on the vertical rod 205, and the disc 209 is rotatably connected to the vertical rod 205.

[0027] In the above embodiment, when the vertical rod 205 rotates, it can drive the fan-shaped sealing plate 302 fixedly connected to it to rotate synchronously, so that the fan-shaped sealing plate 302 periodically blocks the fan-shaped through groove 301 during the rotation. When the fan-shaped sealing plate 302 blocks the fan-shaped through groove 301, the material can be stopped from falling into the fan-shaped through groove 301, thereby avoiding excessive material falling and incomplete adjustment of the material layering structure. At the same time, since the fan-shaped sealing plate 302 is in close contact with the disc 209, even if there is material accumulating on the fan-shaped sealing plate 302 during its rotation, the material can be scraped off by the disc 209.

[0028] In some examples of this application, the dryer has a stirring plate 303 installed inside the flared tube 201, and the stirring plate 303 is fixedly connected to the vertical rod 205. When the user starts the motor 208, the stirring plate 303 rotates along with the vertical rod 205, thereby stirring the material inside the flared tube 201, accelerating the material's falling speed, and preventing material blockage. In addition, an adjustment component is installed on the flared tube 201. This component consists of a disc 209 and a fan-shaped sealing plate 302. The fan-shaped sealing plate 302 controls the amount of material falling by periodically blocking the fan-shaped through slot 301 during rotation, ensuring a more thorough adjustment of the material's stratification structure, and also removing material accumulated on the fan-shaped sealing plate 302.

[0029] In some examples of this application, the stirring plate 303 can be spiral, blade-shaped, or other shapes to adapt to different material mixing requirements. The fan-shaped sealing plate 302 can be made of different materials, such as metal or plastic, to meet different durability and weight requirements. The vertical rod 205 can be rotated using different types of drive devices, such as gear drive or belt drive. The motor 208 can be a DC motor, AC motor, or other types of electric motor to adapt to different working environments and power requirements. The disc 209 can be designed with a different number of fan-shaped slots 301 to adapt to different material handling capacities.

[0030] Specifically, the outer wall of the cylinder 101 is vertically fixedly connected with a plurality of connecting plates 304 that penetrate into its inner wall, and the surfaces of the plurality of connecting plates 304 inside the cylinder 101 are fixedly connected with a plurality of nozzles 305, and the plurality of nozzles 305 are all facing the axis of the cylinder 101.

[0031] Specifically, the upper end face of the connecting plate 304 is fixedly connected to the air outlet of the hot air blower 306, and the hot air blower 306 is fixedly connected to the cylinder 101; the hot air blower 306 should have multiple adjustable heat levels, and when drying materials, the user should adjust the heat of the hot air blower 306 according to the maximum temperature that the material can withstand, so as to avoid damage to the material; and the hot air blower 306 should integrate a power supply for supplying power to it and a switch for controlling its start and stop.

[0032] In the above embodiment, the user can start multiple hot air blowers 306 to generate hot air and continuously deliver it to the connecting plate 304, thereby blowing the hot air onto the material in the cylinder 101 through multiple nozzles 305 fixedly connected on the connecting plate 304, so as to dry the material.

[0033] In some examples of this application, to achieve better drying results, multiple connecting plates 304 are vertically fixedly connected to the outer wall of the cylinder 101, extending to its inner wall. Multiple nozzles 305 are fixedly connected to the surfaces of these connecting plates 304 within the cylinder 101, and all nozzles 305 face the axis of the cylinder 101. This design aims to ensure that hot air is evenly distributed throughout the cylinder 101, improving drying efficiency and quality. Furthermore, the number of nozzles 305 on each connecting plate 304 can be increased to ensure sufficient spray area, further optimizing the drying process. The hot air blower 306 should have multiple adjustable heat settings, allowing the user to adjust the output temperature of the hot air blower 306 according to the maximum temperature the material can withstand, preventing damage to the material due to excessive heat. Simultaneously, the hot air blower 306 integrates a power supply and switch for easy operation and control.

[0034] In some examples of this application, the hot air blower 306 can be a device with different heating elements, such as an electric heater, a gas heater, or an infrared heater. The specific models of these devices can be selected according to actual needs; for example, an electric heater can be selected with a power of 2kW or 3kW, a gas heater can be selected for domestic or industrial use, and an infrared heater can be selected with a wavelength range of 8μm to 15μm. Furthermore, the hot air blower 306 can also include different control systems, such as manual control, automatic control, or remote control.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0037] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0038] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0039] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0040] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
