Description

Technical Field

[0001] The present invention relates to the technical field of agricultural engineering, and specifically to a drying device for cotton straw mulch film production. Background Art

[0002] In agricultural production, mulch film plays an important role in improving crop yields, maintaining soil moisture, suppressing weed growth, etc. As agricultural waste, cotton straw is used to produce mulch film, which not only realizes the reuse of resources but also conforms to the environmental protection concept, becoming an important research direction in the current agricultural field. However, in the process of cotton straw mulch film production, the drying link faces many challenges, and the existing technologies have obvious deficiencies:

[0003] On the one hand, when traditional drying equipment dries cotton straw mulch film, it is difficult to ensure that heat is evenly transferred to all parts of the material. For example, in common hot air drying equipment, the flow distribution of hot air in the equipment is not uniform enough, and local overheating or insufficient drying is likely to occur. This will lead to uneven quality of the mulch film, affecting its physical properties and service life. In actual use, problems such as cracking and insufficient tensile strength may occur, reducing the use effect of the mulch film. On the other hand, some drying devices have design defects, with low heat exchange efficiency and unable to quickly and effectively remove the moisture in the cotton straw mulch film. Some simple drying devices rely on natural ventilation and slow heating, resulting in a long drying time. This not only prolongs the production cycle but also increases the production cost. For large-scale cotton straw mulch film production enterprises, the low-efficiency drying process seriously restricts the expansion of production scale and the improvement of production efficiency. In addition, most existing drying equipment lacks an effective heat recovery structure. During the drying process, a large amount of heat is directly discharged into the environment with the exhaust gas without being fully utilized. This not only causes energy waste, increases the enterprise's energy cost, but also does not conform to the current development trend of energy conservation and environmental protection. In the context of increasingly tight energy, this energy waste phenomenon needs to be solved urgently.

[0004] In summary, it is urgent to develop a drying device for cotton straw mulch film production that can achieve uniform drying, improve drying efficiency, effectively utilize energy, and facilitate real-time monitoring, which is of great significance for promoting the development of the cotton straw mulch film industry.

[0005] In view of this, the purpose of the present invention is to provide a drying device for cotton straw mulch film production to solve the deficiencies existing in the prior art. Summary of the Invention

The function of the second heat preservation sleeve 511 is to keep the heat transferred by the second heat conduction pipe 510.

[0051] Working principle: When the present invention is in use, it specifically includes the following steps:

[0052] First, hot air is generated by the hot air blower 203, and then enters the drying box 201 through the air outlet holes 205 on the first circular plate 204 of the air inlet 202. The first circular plate 204 is driven to rotate by the motor 207, so as to change the blowing angle of the hot air, make the hot air distribution more uniform. At the same time, a plurality of guide plates 209 are installed around the air inlet 202, and then the angle of the guide plates 209 is adjusted by rotating the crank 210 to drive the rotating rod 208 to rotate, further optimizing the flow direction of the hot air, so that the hot air can better contact the materials, thereby improving the drying efficiency.

[0053] Through the synergistic effect of the heat uniformity mechanism 3, then heat is generated by the heating elements 302 on the support frames 301 on both sides of the bottom of the drying box 201. The heat is then transferred through the first heat conduction pipe 303, and the first heat preservation sleeve 304 reduces the heat dissipation. At the same time, one end of the first heat conduction pipe 303 is attached to the outside of one side of the drying box 201 through the heat conduction plate 305, and the heat is evenly transferred into the drying box 201 to ensure that the temperature in the drying box 201 is uniform, avoiding local overheating or uneven drying of the materials.

[0054] The partitions 307 on the plurality of rotating shafts 306 rotatably installed on one side inside the drying box 201 can be adjusted in angle by the electric push rod 309. The electric push rod 309 is installed in the first fixed groove 308, and its output end is connected to the second fixed groove 310, thereby pushing the partition 307 to rotate around the rotating shaft 306. By the partitions 307 at different angles, the placement method of the materials and the flow path of the hot air can be changed. According to the drying degree and characteristics of the materials, the angle of the partition 307 is adjusted to further optimize the drying process and ensure that all parts of the materials can be fully dried.

[0055] During the drying process, the operator can understand the drying situation in real time through the observation mechanism 4. The observation window 401 is opened on the other side of the drying box 201. When observation is needed, the operator slides the baffle plate 404 through the handle 405, making it move in the chute 403 of the fixed block 402, so as to open the observation window 401, which is convenient for the operator to check the drying state of the material, so as to adjust the drying parameters in time.

[0056] The heat utilization mechanism 5 recovers and reuses the heat during the drying process. The humid and hot air discharged through the air outlet 502 on the top plate 501 of the drying box 201 can adjust the discharge amount by controlling the position of the baffle plate 504 through the electric slide rail 503. Then, the air outlet pipe 505 guides the discharged air to other places where heat is needed. Finally, the air is evenly discharged through the air outlet holes 507 on the circular plate 506 at the upper part of the air outlet pipe 505. The heat in the air outlet pipe 505 is transferred to the inside of the material cylinder 509 through the heat conduction pipe 510, which can preheat the materials in the cylinder and other treatments. Also, the heat loss during the heat transfer process is reduced through the heat preservation sleeve 511, improving the energy utilization rate and reducing the production cost.

[0057] The material cylinder 509 on the bearing platform 508 is used to store the materials to be dried. During the whole drying process, the materials are taken out from the material cylinder 509 and put into the drying box 201, and then taken out after drying treatment to complete the drying process. Through the coordinated action of each mechanism of the whole device, the efficient and uniform drying of cotton straw mulch materials is realized. At the same time, the heat is fully utilized, improving the energy utilization rate and production efficiency, and meeting the drying requirements in the production process of cotton straw mulch.
