Description

Technical Field

[0001] This utility model relates to the field of material drying technology, specifically a drying device for granular materials. Background Technology

[0002] To achieve effective drying of particulate materials, hot air is typically used as the heat source. The moisture in the material is removed through heat exchange between the hot air and the material. Currently, when hot air comes into contact with stacked particulate materials, the outer surface of the material is directly exposed to the hot air. The particles on the outer surface quickly absorb heat and evaporate moisture, easily leading to over-drying. This over-drying can cause the material surface to harden and crack, and may also affect the material's subsequent processing and performance. Simultaneously, because hot air has difficulty penetrating the interior of the material pile, the internal particles receive limited heat, resulting in slower moisture evaporation. This can lead to incomplete drying of the internal particles, causing a decline in the quality of the particulate material.

[0003] The existing Chinese patent publication number CN2786517Y describes a granular material drying device, which includes a closed heating chamber and a drum driven by a drive device. During the drying process, the material continuously rolls with the rotation of the drum, and the heat generated by the far-infrared heating element is directly applied to the material inside the drum, resulting in uniform heating. Moreover, under the action of the exhaust device, a negative pressure is formed in the heating chamber, and the moisture generated during the drying process can be efficiently discharged from the heating chamber, resulting in high thermal efficiency. It is not only suitable for drying granular materials, but also for coating and moisture-proofing granules, pills, and tablets. However, the uniform drying of granular materials inside the drum will result in uneven and incomplete heating of individual granules, thereby reducing the quality of the granules.

[0004] The existing fluidized bed drying system for particulate materials, published in Chinese Patent Publication No. CN221684938U, includes a drying cylinder, a support component, and a drying and cooling mechanism. The drying and cooling mechanism is used to dry and cool the particulate materials inside the drying cylinder. This solves the problem that existing materials are only dried, but the high residual temperature on the material surface tends to accumulate and clump together, leading to a reduction in material quality. However, the center of the particulate materials accumulated inside the drying cylinder is not easily heated, which will reduce the degree of drying of the particulate materials and thus reduce the product quality of the particulate materials.

[0005] Therefore, in order to address the above problems, the applicant needs to design a drying device for particulate materials to solve the problem. Utility Model Content

[0006] The purpose of this invention is to provide a drying device for particulate materials to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drying device for particulate materials, comprising a conveying mechanism for conveying particulate materials, a drying mechanism located above the conveying mechanism for drying the particulate materials, and a collection mechanism located below the conveying mechanism for collecting the dried particulate materials.

[0008] The conveying mechanism includes a conveyor for conveying particulate materials, and the conveyor is provided with a plurality of rollers spaced apart by a distance smaller than that of the particulate materials.

[0009] The drying mechanism includes a drying chamber located above the conveyor, and an air outlet pipe is connected to the drying chamber by a mechanical seal. A hot air blower is provided at the air inlet end of the air outlet pipe, and the hot air blower is used to provide hot air to the air outlet pipe.

[0010] The collection mechanism includes a collection chamber installed below the output end of the conveyor, and a number of buffer springs are fixedly installed on the bottom surface of the collection chamber. One end of each of the buffer springs is fixedly provided with a buffer plate, and the buffer plate is slidably connected to the inner wall of the collection chamber.

[0011] Furthermore, the output end of the conveyor is fixedly equipped with an arc-shaped guide chamber, which is located obliquely above the collection chamber for introducing dried granular material into the collection chamber.

[0012] Furthermore, the feed end of the conveyor is provided with a feeding plate, and the bottom surface of the feeding plate forms a 5-degree angle with the plane containing the end face of the roller.

[0013] Furthermore, both the input and output ends of the drying chamber are equipped with movable doors via spring hinges, and the movable doors are used to close the drying chamber.

[0014] Furthermore, a mounting block is fixedly installed on the bottom surface of the hot air blower, and the mounting block is fixedly connected to the conveyor.

[0015] Furthermore, a fixing block is fixedly provided on the bottom surface of the conveyor, and a sliding groove is provided on the fixing block. An extended sliding plate is integrally provided on the collection bin, and the extended sliding plate cooperates with the sliding groove for sliding installation of the collection bin.

[0016] Furthermore, a support frame is fixedly installed on the bottom surface of the conveyor, and pads are provided below the support frame.

[0017] Compared with existing technologies, the beneficial effects of this utility model are: This granular material drying device, through its efficient feeding device, stable drying chamber, and safe collection design, achieves automated, efficient, and safe processing of granular materials, providing strong support for the production and processing of granular materials and ensuring a dual improvement in the quality and efficiency of the final product. Specific details are as follows:

[0018] When using this granular material drying device, the extended sliding plate on the collection bin is inserted into the chute, and then the granular material is placed on the conveying mechanism. The conveying mechanism, through rotating conveying rollers, orderly feeds the granular material into the drying bin. Hot air provided by a hot air blower in the drying bin quickly and completely covers the outer surface of the granular material, achieving a rapid and thorough drying effect. This significantly shortens the drying cycle of the granular material and effectively avoids the problem of quality degradation of the granular material that may be caused by insufficient drying or excessive drying time. After drying is completed, the granular material will roll into the collection bin through an arc-shaped guide plate, facilitating unified processing of the dried granular material. This achieves automated, efficient, and safe processing of granular materials, providing strong support for the production and processing of granular materials and ensuring a dual improvement in the quality and efficiency of the final product.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, a drying device for granular materials according to this utility model includes a conveying mechanism 1 for conveying granular materials, a drying mechanism 2 located above the conveying mechanism 1 for drying granular materials, and a collecting mechanism 3 located below the conveying mechanism 1 for collecting dried granular materials. The conveying mechanism 1 includes a conveyor 10 for conveying granular materials, and the conveyor 10 is provided with a plurality of rollers spaced apart by a distance smaller than that of the granular materials. The drying mechanism 2 includes a drying chamber 20 located above the conveyor 10, and the drying chamber 20 is connected to an air outlet pipe 21 by a mechanical seal. A hot air blower 22 is provided at the air inlet end of the air outlet pipe 21, and the hot air blower 22 is used to provide hot air to the air outlet pipe 21. The collecting mechanism 3 includes a collecting chamber 30 installed below the output end of the conveyor 10, and a plurality of buffer springs 31 are fixedly provided on the inner bottom surface of the collecting chamber 30. A buffer plate 32 is fixedly provided at one end of the plurality of buffer springs 31, and the buffer plate 32 is slidably connected to the inner wall of the collecting chamber 30.

[0026] An arc-shaped guide chamber 12 is fixedly installed at the output end of the conveyor 10. The arc-shaped guide chamber 12 is located diagonally above the collection chamber 30 and is used to introduce the dried granular material into the collection chamber 30. The arc-shaped guide chamber 12 enables a smooth transition of the dried granular material from the conveyor 10 to the collection chamber 30. Its arc-shaped structure reduces the impact force and sudden change in the direction of movement when the material falls, and avoids damage or splashing of the particles due to direct collision.

[0027] The feed end of the conveyor 10 is equipped with a feeding plate 11, and the bottom surface of the feeding plate 11 forms a 5-degree angle with the plane where the end face of the roller is located. The inclined design of the feeding plate 11 and the end face of the roller at a 5-degree angle optimizes the initial feeding process of granular materials. It can not only use gravity to assist the material to slide naturally towards the roller, avoiding accumulation or blockage at the feed end, but also maintain the stability of the material on the roller through a limited inclination, preventing uncontrolled rolling due to excessive angle.

[0028] Both the input and output ends of the drying chamber 20 are equipped with movable doors 24 via spring hinges. The movable doors 24 are used to close the drying chamber 20. When particulate material passes through, the movable doors 24 are automatically opened by the pushing force of the material and then quickly closed by the action of the spring. This effectively isolates the intrusion of external cold air and the loss of internal heat, ensuring the stability of the internal thermal environment of the drying chamber 20 and avoiding the obstruction of material flow by the traditional fixed door structure, thus significantly improving the efficiency of heat energy utilization.

[0029] A mounting block 23 is fixedly installed on the bottom surface of the hot air blower 22, and the mounting block 23 is fixedly connected to the conveyor 10. The mounting block 23 fixes the hot air blower 22 to the conveyor 10 to form an integral rigid structure, thereby improving the stability and stability of the hot air blower 22 during use.

[0030] A fixing block 33 is fixedly installed on the bottom surface of the conveyor 10, and a chute 34 is provided on the fixing block 33. An extension slide plate 35 is integrally provided on the collection bin 30, and the extension slide plate 35 cooperates with the chute 34 to slide and install the collection bin 30. The cooperation structure of the chute 34 and the extension slide plate 35 realizes the sliding and disassembly installation of the collection bin 30, which can quickly pull out the collection bin 30 along the chute 34 for material cleaning or replacement, greatly simplifying the maintenance process.

[0031] A support frame 4 is fixedly installed on the bottom surface of the conveyor 10, and a foot 5 is installed below the support frame 4. The combination of the support frame 4 and the foot 5 provides double stability protection for the conveyor 10, thereby improving the stability and stability of the conveyor 10 during use.

[0032] Working Principle: When using this granular material drying device, firstly, the device is equipped with several rollers spaced smaller than the granular material itself. These rollers are specifically designed to accommodate and stably transport the granular material. These rollers not only ensure the stability of the material during transport but also guide the granular material forward in an orderly manner through their rotation, laying a solid foundation for subsequent processing steps. Next, the granular material is guided one by one into the drying chamber 20 by a conveyor 10 equipped with several rollers. The entrance to the drying chamber 20 is equipped with a movable door 24 with spring hinges, which effectively isolates heat exchange between the inside and outside of the drying chamber 20, minimizing heat loss and ensuring the energy efficiency of the drying process. Once the granular material enters the drying chamber 20, it will be dried by a hot airflow. This hot airflow comes from a high-efficiency hot air fan 22, which connects to the drying chamber 20 through an outlet duct 21. The mechanical seal connection continuously supplies hot air into the drying chamber 20. This hot air quickly and completely covers the outer surface of the granular material, achieving a rapid and thorough drying effect. This not only significantly shortens the drying cycle but also effectively avoids the problem of granular material quality degradation that may occur due to insufficient drying or excessive drying time, ensuring the quality of the final product. After the drying process is completed, the conveying mechanism 1 uses the arc-shaped guide chamber 12 to send the dried granular material into the detachable collection chamber 30. In addition, the collection chamber 30 is equipped with a buffer plate 32 and a buffer spring 31. When the granular material falls onto the buffer plate 32, it is effectively absorbed by the buffer spring 31, effectively preventing the granular material from being damaged due to falling. This realizes the automated, efficient, and safe processing of granular materials, providing strong support for the production and processing of granular materials and ensuring a dual improvement in the quality and efficiency of the final product.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
