Description

Technical Field

[0001] The utility model relates to the field of drying equipment, in particular to dehydration mechanisms on both sides of the drying equipment. Background Art

[0002] Coal powder drying is an important industrial process aimed at removing moisture from coal powder, increasing its calorific value and combustion efficiency. The moisture content in coal powder is inversely proportional to its calorific value. By drying to reduce the moisture content, the calorific value of coal powder can be significantly increased. The density of the dried coal powder increases, the particle size is uniform, and it is easier to mix with air, thereby improving combustion efficiency and stability. The volume and mass density of the dried coal powder increase, reducing the need for transportation and storage space and lowering related costs. The soot generated during the combustion of dried coal powder decreases, contributing to reducing environmental pollution. There are various methods for drying coal powder, commonly including hot air drying, vacuum drying, microwave drying, etc. Among them, hot air drying is widely used due to its fast heat transfer and high efficiency. Coal powder contains certain moisture and chemical substances, and these components may undergo hydration reactions during long-term storage, resulting in changes in the physical structure of coal powder, which is then prone to caking. At the same time, when the environmental temperature and humidity are high, the moisture in coal powder will increase, and thus the risk of caking will also increase. After coal powder cakes, the contact between the internal coal powder particles becomes closer, making it difficult for hot air to effectively penetrate inside the cake, resulting in a decrease in the heat conduction efficiency during the drying process. This means that a longer time or a higher temperature is required to achieve the desired drying effect, thereby increasing the drying cost. Therefore, dehydration mechanisms on both sides of the drying equipment are needed to solve the above problems. Content of the Utility Model

[0003] The main purpose of the utility model is to provide dehydration mechanisms on both sides of the drying equipment, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] The dehydration mechanisms on both sides of the drying equipment include a top bin body. There are two top bin bodies, which are symmetrically and fixedly installed at the upper end of the drying equipment box body. One end of the top bin body is fixedly installed with an installation platform, and a drying component is fixedly installed on the installation platform. A air distribution component is fixedly installed on the top bin body, and the air distribution component is connected to the drying component at the same time. The air distribution component consists of a connecting pipe, an air distribution pipe, and an air outlet protection net. The air distribution pipe is fixedly connected to the connecting pipe. Air outlets are opened on the air distribution pipe, and the air outlet protection net is fixedly installed in the air outlets. A dispersing device is also installed on the top bin body. The dispersing device consists of a motor, a rotating shaft, and perforated dispersing plates. The rotating shaft is fixedly installed on the output shaft of the motor, and there are several perforated dispersing plates, all of which are fixedly installed on the outer wall of the rotating shaft.

[0006] Preferably, an insertion slot is formed in the upper side wall of the top bin body, and the insertion slot penetrates the upper side wall of the top bin body up and down. A bin is fixedly inserted in the insertion slots formed in the two top bin bodies.

[0007] Preferably, a blanking hopper is fixedly installed at the lower end of the drying equipment box body.

[0008] Preferably, the drying assembly is composed of a fan and an air heating device, and the fan and the air heating device are fixedly connected through a pipeline. At the same time, both the fan and the air heating device are fixedly connected to the installation platform.

[0009] Preferably, the connecting pipeline on the air distribution assembly passes through the upper side wall of the top bin body, and the connecting pipeline is fixedly connected to the air heating device. The air distribution pipeline is located inside the top bin body.

[0010] Preferably, the motor on the dispersing device is fixedly installed at the outer end of the top bin body, the rotating shaft is rotatably installed inside the top bin body, and both the rotating shaft and the perforated dispersing plate are located directly below the insertion slot.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By arranging two sets of dispersing devices and two sets of air distribution assemblies on the two top bin bodies, the dispersing device can disperse the caked pulverized coal falling from the bin into the top bin body. At the same time, the dispersing device can also disperse the non-caked pulverized coal. Combined with the air distribution assembly, it can make the pulverized coal fully contact with the hot air, thereby accelerating the drying efficiency of the pulverized coal, reducing the time required for drying the pulverized coal, and further reducing the drying cost; the cooperation of the two sets of air distribution assemblies and the two sets of drying assemblies can control the air pressure in the top bin body and the drying equipment box body. By controlling the air pressure, the residence time and flow path of the pulverized coal in the top bin body and the drying equipment box body can be adjusted, so as to optimize the dehydration effect. And when the air pressure increases, the air flow speed increases, increasing the convective heat transfer coefficient of the air on the surface of the pulverized coal, making the moisture on the surface of the pulverized coal easier to evaporate. In addition, the high air pressure can also bring a lower relative humidity environment, further promoting the evaporation of moisture. At the same time, the air pressure and temperature act synergistically. The high air pressure can promote the penetration and distribution of hot air in the pulverized coal, improving the overall drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the dehydration mechanisms on both sides of the drying equipment include the top bin bodies 1. There are two top bin bodies 1, which are symmetrically and fixedly installed at the upper end of the drying equipment box body 2. One end of the top bin body 1 is fixedly installed with an installation platform 8, and a drying component 3 is fixedly installed on the installation platform 8. An insertion slot 9 is opened on the upper side wall of the top bin body 1, and the insertion slot 9 penetrates the upper side wall of the top bin body 1 up and down. A material bin 7 is fixedly inserted into the insertion slots 9 opened on the two top bin bodies 1. A blanking hopper 6 is fixedly installed at the lower end of the drying equipment box body 2. The drying component 3 is composed of a fan 10 and an air heating device 11, and the fan 10 and the air heating device 11 are fixedly connected by a pipeline. At the same time, both the fan 10 and the air heating device 11 are fixedly connected to the installation platform 8. A air distribution component 4 is fixedly installed on the top bin body 1, and the air distribution component 4 is connected to the drying component 3 at the same time. The air distribution component 4 is composed of a connecting pipeline 12, an air distribution pipeline 13 and an air distribution port protection net 14. The air distribution pipeline 13 is fixedly connected to the connecting pipeline 12. Air distribution ports are opened on the air distribution pipeline 13, and the air distribution port protection net 14 is fixedly installed in the air distribution ports. A dispersing device 5 is also installed on the top bin body 1. The dispersing device 5 is composed of a motor 15, a rotating shaft 16 and a perforated dispersing plate 17. The rotating shaft 16 is fixedly installed on the output shaft of the motor 15. There are several perforated dispersing plates 17, and they are all fixedly installed on the outer wall of the rotating shaft 16. When drying pulverized coal, the pulverized coal can be put into the material bin 7, and then the pulverized coal will fall into the top bin body 1 under the influence of gravity. At the same time, the drying component 3 and the dispersing device 5 can be started. At this time, the motor 15 on the dispersing device 5 will drive the rotating shaft 16 and the perforated dispersing plate 17 to rotate at a high speed. At this time, the caked pulverized coal falling into the top bin body 1 will collide with the rotating shaft 16 and the perforated dispersing plate 17 rotating at a high speed. Therefore, the rotating shaft 16 and the perforated dispersing plate 17 rotating at a high speed can break up the caked pulverized coal and also disperse the non-caked pulverized coal. The air heating device 11 on the drying component 3 will heat the air, and the heated air will be blown into the air distribution component 4 by the fan 10. Then the air will flow along the connecting pipeline 12 and the air distribution pipeline 13 in turn. Finally, the hot air will be blown out from the mesh holes of the air distribution port protection net 14. Thus, the hot air can fully contact with the pulverized coal dispersed and broken up by the rotating shaft 16 and the perforated dispersing plate 17. Furthermore, the pulverized coal will be dried. Finally, the dried pulverized coal will fall out from the blanking hopper 6. By setting two groups of dispersing devices 5 and two groups of air distribution components 4 on the two top bin bodies 1, the dispersing device 5 can break up the caked pulverized coal falling into the top bin body 1 from the material bin 7, and at the same time, the dispersing device 5 can also disperse the non-caked pulverized coal. Combined with the air distribution component 4, it can make the pulverized coal fully contact with the hot air, thereby accelerating the drying efficiency of the pulverized coal, reducing the time required for drying the pulverized coal, and further reducing the drying cost.

[0020] Further, the connecting pipe 12 on the air distribution assembly 4 passes through the upper side wall of the top bin 1, and the connecting pipe 12 is fixedly connected to the air heating device 11. The air distribution pipe 13 is located inside the top bin 1. The air distribution pipe 13 and the air outlet protective net 14 on the air distribution assembly 4 can evenly distribute the hot air generated by the drying assembly 3 into the top bin 1, so that the hot air can evenly contact the pulverized coal.

[0021] Further, the motor 15 on the dispersing device 5 is fixedly installed at the outer end of the top bin 1, the rotating shaft 16 is rotatably installed inside the top bin 1, both the rotating shaft 16 and the perforated dispersing plate 17 are located directly below the insertion slot 9. Through holes are formed in the perforated dispersing plate 17. The existence of these through holes can improve the efficiency of the perforated dispersing plate 17 in dispersing the agglomerated pulverized coal. At the same time, the existence of these through holes can also reduce the weight of the perforated dispersing plate 17, thereby reducing the burden on the motor 15 and further reducing the power consumption of the motor 15.
