Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a compound countercurrent dynamic drying device. Background Technique

[0002] In industrial production, the drying treatment of wet mass-like or paste-like high-viscosity and high-moisture materials (such as food raw materials, chemical raw materials, pharmaceutical intermediates, etc.) is a key and complex link. Due to their high viscosity and high moisture content, traditional single drying methods often face many challenges. Specifically, most traditional drying equipment relies on a single heat source (such as hot air, infrared radiation, etc.) to dry the materials, and this method has obvious limitations when dealing with high-viscosity and high-moisture materials.

[0003] Firstly, a single drying source is difficult to effectively penetrate the interior of the materials, resulting in slow evaporation of moisture inside the materials and low drying efficiency. Especially when the material thickness is large or the shape is irregular, the external drying source is difficult to act evenly on the whole material, easily causing uneven drying and affecting product quality.

[0004] Secondly, high-viscosity materials are prone to caking during the drying process, further reducing the drying efficiency. Traditional drying equipment often lacks an effective crushing mechanism and cannot crush the materials during drying, which not only prolongs the drying time but also increases the difficulty and cost of subsequent processing.

[0005] In addition, operation efficiency is also a major problem faced by traditional drying equipment. Due to factors such as low drying efficiency and uneven material processing, operators need to spend more time and energy on monitoring and adjustment, which not only increases the labor intensity but also affects the overall efficiency of the production line.

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Refer to Figures 1-5 , a compound convection dynamic drying device, including a drying cylinder 2 and a rotating rod 3. The rotating rod 3 is arranged at the center inside the drying cylinder 2. A drive motor 5 is installed at the center of the bottom of the drying cylinder 2. The output shaft of the drive motor 5 penetrates through the bottom of the drying cylinder 2 through a shaft sleeve and is in transmission connection with the end of the rotating rod 3;

[0026] An annular air inlet pipe 1 is arranged at the bottom of the outer circle of the drying cylinder 2. A plurality of air supply modules are arranged on the inner circle of the annular air inlet pipe 1. One end of the air supply module is communicated with the inside of the annular air inlet pipe 1, and the other end is communicated with the inside of the drying cylinder 2. A plurality of cutting blades 11 are detachably connected to the outer circle of the rotating rod 3. One side of the annular air inlet pipe 1 is communicated with an air supply pipe 7.

[0027] This solution has the following working process:

[0028] The drying equipment designed in this technical solution is mainly used for efficient drying of wet mass or paste-like high-viscosity and high-moisture materials. At the beginning of work, the material to be dried is first put into the drying cylinder 2. Subsequently, the drive motor 5 is started. Its output shaft penetrates through the bottom of the drying cylinder 2 through a shaft sleeve and directly drives the rotating rod 3 to rotate at the center inside the drying cylinder 2. A plurality of cutting blades 11 detachably connected to the outer circle of the rotating rod 3 rotate accordingly, cutting and crushing the material, effectively preventing the material from caking during the drying process, ensuring that the material can be evenly heated, and improving the drying efficiency.

[0029] Meanwhile, the annular intake pipe 1 is connected to hot air or other suitable gas media through the air supply pipe 7. A number of air supply modules arranged on the inner circle of the annular intake pipe 1 evenly distribute the hot air and send it into the interior of the drying cylinder 2, making full contact with the rotating material. This way of intake air from the bottom ring, combined with the crushing effect inside the material, enables the hot air to penetrate more effectively into the interior of the material, promotes the rapid evaporation of moisture, and improves the drying uniformity and efficiency.

[0030] During the entire drying process, the operator can adjust the rotation speed of the drive motor 5 and the temperature and flow rate of the gas in the air supply pipe 7 according to the material characteristics and drying requirements to achieve the best drying effect.

[0031] According to the above working process, it can be known that:

[0032] Efficient penetration and uniform drying: By combining the internal crushing mechanism, the cutting blades 11 rotate with the rotating rod 3, and the external annular intake air system, the annular intake pipe 1 and the air supply modules, this technical solution can effectively penetrate the interior of high-viscosity and high-moisture materials, achieve uniform drying, significantly improve the drying efficiency, and solve the problem that traditional drying methods are difficult to act uniformly on the whole material.

[0033] Prevent caking and optimize processing: The cutting blades 11 cut and crush the material during rotation, effectively preventing the material from caking during drying, not only accelerating the moisture evaporation speed, but also simplifying the subsequent processing flow, reducing the processing difficulty and cost.

[0034] Flexible adjustment and strong adaptability: The rotation speed of the drive motor 5 and the temperature and flow rate of the gas in the air supply pipe 7 can be adjusted according to the material characteristics and drying requirements, making the drying equipment highly flexible and adaptable, and capable of meeting the drying processing requirements of different types and states of materials.

[0035] Improve operation efficiency and reduce labor intensity: Due to the high drying efficiency and uniform material processing, the operator does not need to spend too much time and energy on monitoring and adjustment, thus reducing the labor intensity and improving the overall efficiency of the production line. In addition, the detachable design of the cutting blades 11 is also convenient for maintenance and replacement, further enhancing the usability and reliability of the equipment.

[0036] Further, the diameter of the annular intake pipe 1 is larger than the diameter of the drying cylinder 2. A heat insulation sleeve is sleeved on the outer circle of the annular intake pipe 1. One end of each cutting blade 11 is fixedly connected with a mounting plate 10, and one side of the mounting plate 10 is bolt-fixed to the side wall of the rotating rod 3.

[0037] Further, a number of mounting holes 6 are opened at the bottom of the outer circle of the drying cylinder 2, and the number of mounting holes 6 is annularly arranged along the circumferential direction of the drying cylinder 2.

[0038] Furthermore, several support rods 4 are provided at the bottom of the drying cylinder 2, and the several support rods 4 are annularly arranged along the circumferential direction of the drying cylinder 2.

[0039] Furthermore, the air supply module includes a connecting pipe 12 and an air outlet plate 9 provided at one end of the connecting pipe 12. One end of the connecting pipe 12 is communicated with the inside of the annular air inlet pipe 1. The other end of the connecting pipe 12 passes through the mounting hole 6 through a sealing sleeve. Several air outlet holes are provided on one side of the air outlet plate 9, and one side of the air outlet plate 9 is detachably connected to the side wall of the connecting pipe 12.

[0040] Furthermore, a docking pipe 8 is fixedly connected to one side of the air outlet plate 9. Internal threads are provided on the inner circle of one end of the connecting pipe 12, external threads are provided on the outer circle of the docking pipe 8, and an arc edge is provided on the outer circle of the air outlet plate 9.

[0041] Detailed working process:

[0042] The drying equipment designed in this technical solution aims to efficiently process wet lumpy or paste-like high-viscosity and high-moisture materials. Before starting work, the materials are put into the drying cylinder 2, and the bottom of the drying cylinder 2 is stably supported by the support rods 4. Subsequently, the driving motor 5 is started, and its output shaft passes through the bottom of the drying cylinder 2 to drive the rotating rod 3 to rotate in the center of the cylinder. The cutting blades 11 on the rotating rod 3 are bolted to the side wall of the rotating rod 3 through their respective mounting plates 10 and rotate synchronously with the rotating rod 3 to finely cut and crush the materials, effectively preventing the materials from caking and promoting uniform heating.

[0043] At the same time, hot air or other suitable gases are introduced into the annular air inlet pipe 1 through the air supply pipe 7. The diameter of the annular air inlet pipe 1 is larger than that of the drying cylinder 2, and a heat insulation sleeve is sleeved outside it to reduce heat dissipation. The air supply module in the annular air inlet pipe 1 starts to work. Each air supply module consists of a connecting pipe 12 and an air outlet plate 9. One end of the connecting pipe is communicated with the annular air inlet pipe 1, and the other end passes through the mounting hole 6 at the bottom of the drying cylinder 2 through a sealing sleeve. The mounting holes 6 are annularly arranged along the circumferential direction of the drying cylinder 2 to ensure uniform distribution of the gas. Multiple air outlet holes are provided on the air outlet plate 9 and are fixedly connected to the side wall of the connecting pipe through a detachable connection method, which is convenient for maintenance and replacement. In particular, the air outlet plate 9 is also provided with a docking pipe 8, which is tightly docked with the connecting pipe through internal and external threads, and the outer circle of the air outlet plate 9 is designed as an arc edge to reduce air flow resistance.

[0044] With the operation of the air supply module, hot air is evenly ejected from the air outlet holes and fully contacts the materials cut and crushed inside. The way of introducing air from the bottom annularly combined with the crushing effect inside the materials enables the hot air to penetrate deep into the materials, accelerating the evaporation of moisture and achieving an efficient and uniform drying effect.

[0045] During the entire drying process, the operator can flexibly adjust the rotational speed of the drive motor 5, the temperature and flow rate of the gas in the air supply pipe 7 according to the specific characteristics of the material and the drying requirements, so as to achieve the best drying effect. After drying is completed, all power systems are shut down, and the dried material is discharged through an appropriate method.

[0046] Detailed beneficial effects:

[0047] Efficient penetration and uniform drying: Through the perfect combination of the cutting blade 11 rotating with the rotating rod 3 in the internal crushing mechanism and the external annular air intake system including the annular air intake pipe 1 and the air supply module, this technical solution effectively penetrates the inside of the highly viscous and high-moisture material, realizing uniform and efficient drying treatment, and overcoming the problem that traditional drying methods are difficult to act uniformly on the whole material.

[0048] Prevent caking and optimize the processing flow: The cutting and crushing effects of the cutting blade 11 during rotation effectively prevent the material from caking, not only improving the water evaporation speed, but also simplifying the subsequent material processing flow, reducing the processing difficulty and cost, and improving the overall production efficiency.

[0049] High flexibility and adaptability: The adjustable rotational speed of the drive motor 5 and the temperature and flow rate of the gas in the air supply pipe 7 endow this drying equipment with high flexibility and wide adaptability, and can easily meet the drying treatment requirements of different types and states of materials, satisfying diverse production scenarios.

[0050] Improve operation efficiency and reduce labor intensity: The high drying efficiency and uniform material processing enable the operator not to monitor and adjust frequently, thus reducing the labor intensity and improving the overall operation efficiency of the production line. At the same time, the detachable design of components such as the cutting blade 11 and the air outlet plate 9 facilitates daily maintenance and replacement, further enhancing the usability and reliability of the equipment.

[0051] Optimized structure and reduced heat loss: The design that the diameter of the annular air intake pipe 1 is larger than that of the drying cylinder 2 and an insulating sleeve is sleeved outside effectively reduces the heat loss during transmission, improving the energy utilization efficiency. In addition, the arc-edge design of the air outlet plate 9 also reduces the air flow resistance and improves the air supply efficiency.
