Description

Technical Field

[0001] The utility model relates to the technical field of feed dryers, and particularly relates to a circulating filter screen with multi-plate compact arrangement and high temperature resistance for a dryer. Background Art

[0002] In the feed production process, as a key device, the performance of the dryer is directly related to the final quality of the product and the long-term operation of the device. As a core component inside the dryer, the circulating filter screen's efficiency and stability cannot be ignored. In view of this, the technical R & D personnel in this field are committed to seeking innovative solutions to optimize the performance of the dryer. Different from the existing technologies, such as the seed drying device disclosed in Chinese Patent CN112964045A, although the drying efficiency and the contact area of hot air are improved through the design of electric heating rods and rotating corrugated pipes, there is still room for improvement in the structural design of the circulating filter screen. Currently, the common problems of the circulating filter screen of the dryer include loose structure, poor heat resistance, easy deformation, and unsmooth rotation. These problems not only limit the improvement of the drying efficiency but also significantly increase the maintenance burden and cost of the device. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a circulating filter screen with multi-plate compact arrangement and high temperature resistance for a dryer.

[0004] The technical scheme adopted by the utility model is as follows:

[0005] A circulating filter screen with multi-plate compact arrangement and high temperature resistance for a dryer, including a circulating filter screen located in the dryer body. The circulating filter screen has at least two layers. Each layer of the circulating filter screen includes a high-temperature resistant filter screen and a support plate arranged inside the high-temperature resistant filter screen. The adjacent support plates are compactly arranged; the support plate includes a hinge unit and a support unit, where:

[0006] The hinge unit includes a long metal piece with hinge holes respectively arranged at both ends; a hinge shaft penetrates through the adjacent hinge holes;

[0007] The support unit includes a back plate connected to the hinge shaft and a metal partition supporting the back plate; the tops of the paired metal partitions are bent inward; a support beam is fixed between the bent metal partitions.

[0008] This technical solution effectively increases the contact area and time between hot air and materials by setting at least two layers of circulating filters, thereby improving the drying efficiency; the multi-layer filters can also gradually filter out impurities and particles in the materials to ensure the cleanliness of the dried products; the compact arrangement between adjacent support plates reduces the resistance of air flow, enabling hot air to pass through the filters more smoothly and further improving the thermal circulation efficiency; the filters made of high-temperature resistant materials can withstand the high temperature generated during the drying process, ensuring that the filters will not deform or be damaged due to high temperature, thus extending the service life of the equipment; the support plates formed by the combination of the hinge unit and the support unit not only provide sufficient structural strength to support the filters, but also maintain a stable shape in a high-temperature environment, preventing deformation or loosening caused by thermal expansion and contraction; the long strip metal parts are connected by hinge shafts, making the support plates have a certain degree of flexibility, facilitating the adjustment of the position and angle of the filters during installation and disassembly, and also being able to adapt to the slight deformation caused by temperature changes during the drying process to a certain extent; the entire filter system consists of multiple modular support plates and filters. This design allows for the individual disassembly and replacement of damaged parts when the filters need to be replaced or repaired, without shutting down the entire system, thereby improving the maintainability and operating efficiency of the equipment; the top of the metal partition is bent inward and fixed with a support beam to enhance the overall structural strength of the support plate, enabling it to withstand various forces and vibrations generated during the drying process and ensuring the long-term stable operation of the equipment.

[0009] In addition, the circulating filter of the multi-plate compact arrangement high-temperature resistant dryer proposed above according to the present utility model further has the following additional technical features:

[0010] According to an embodiment of the present utility model, the high-temperature resistant filter is woven from PUC material.

[0011] In this technical solution, the filter made of PUC material can effectively filter out impurities and particles in the materials to ensure the cleanliness of the dried products; in a high-temperature environment, the PUC material can maintain the stability of its physical and chemical properties, thus ensuring that the filter will not fail during the high-temperature drying process.

[0012] According to an embodiment of the present utility model, the aperture of the high-temperature resistant filter is 0.8 - 1.0 mm.

[0013] In this technical solution, during the feed drying process, hot air needs to quickly and evenly penetrate the material layer to achieve the purpose of rapid drying. An appropriate aperture size is crucial for ensuring the air circulation and drying efficiency of hot air. The aperture size of 0.8 - 1.0 mm is a reasonable choice after considering various factors such as filtration accuracy, air circulation, and structural strength. The feed quickly tumbles on the high-temperature resistant filter, and the excess moisture and filtered dust are discharged by the negative pressure motor, achieving a high cleanliness of the feed.

[0014] According to an embodiment of the present utility model, mounting holes for connecting the hinge shaft are provided on the back plate, and a metal partition is welded to the back side of the back plate.

[0015] In this technical solution, the metal partition acts as a strengthening member, which can resist external pressure and deformation, ensuring that the filter screen maintains its shape and stability under high temperature and mechanical stress; at the same time, the metal partition also acts as an intermediate structure, and a support beam for strengthening the connection is further provided on its top.

[0016] According to an embodiment of the present utility model, the spacing distance between the metal partitions is smaller than the spacing of the hinge shafts, and the metal partitions are arranged in a compact manner.

[0017] In this technical solution, the space between the metal partitions is effectively utilized, reducing the voids in the structure, enhancing the stability of the entire support structure, preventing deformation or vibration under high temperature or mechanical stress, effectively dispersing and resisting external loads, and ensuring the rigidity of the filter screen frame. In addition, during the cyclic rotation of the high-temperature resistant filter screen, the metal partitions with smaller spacing make the overall cyclic rotation of the filter screen smoother without jamming or other phenomena.

[0018] According to an embodiment of the present utility model, the support beam is a strengthening member spaced on the top of the metal partition.

[0019] In this technical solution, in a high-temperature environment, the filter screen and the support plate will deform due to thermal expansion; the spaced arrangement of the support beams allows these components to have a certain degree of freedom during expansion, thereby reducing the risk of damage caused by thermal stress; at the same time, the support beam itself also has a certain elasticity and can absorb part of the stress generated by thermal expansion.

[0020] Compared with the prior art, the present utility model has the following beneficial effects:

[0021] (1) By providing at least two layers of cyclic filter screens, the contact area and time between hot air and materials are effectively increased, thereby improving the drying efficiency;

[0022] (2) The high-temperature resistant filter screen is woven with PUC material, which can maintain the stability of its physical and chemical properties, thus ensuring that the filter screen will not fail during the high-temperature drying process;

[0023] (3) During the cyclic rotation of the high-temperature resistant filter screen, the metal partitions with smaller spacing make the overall cyclic rotation of the filter screen smoother without jamming or other phenomena. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In addition, the circulating filter of the multi-plate compact arrangement high-temperature resistant dryer proposed above according to the present invention also has the following additional technical features:

[0036] According to an embodiment of the present invention, the aperture of the high-temperature resistant filter is 0.8 - 1.0 mm.

[0037] In this technical solution, during the feed drying process, hot air needs to quickly and evenly penetrate the material layer to achieve the purpose of rapid drying. The appropriate aperture size is crucial for ensuring the air circulation and drying efficiency of hot air.
