Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a guide fin structure in a dryer. Background Technology

[0002] During the operation of the dryer, the guide fins are key components that guide the hot air to be evenly distributed and ensure the drying quality of the materials.

[0003] Currently, most existing dryer guide fins adopt conventional flat or simple folded plate structures, with relatively flat surfaces. This results in limited contact area between the hot air and the fins during the airflow process, preventing the hot air from fully contacting the material and reducing the utilization efficiency of the hot air. At the same time, conventional guide fins have poor heat dissipation performance. Under prolonged high-temperature operating conditions, heat easily accumulates on the fins, which not only affects the service life of the fins but also makes it difficult to accurately control the hot air temperature, thus affecting the drying effect of the material and causing uneven drying. Therefore, this utility model proposes a guide fin structure in a dryer to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a guide fin structure for a dryer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide fin structure in a dryer, including a guide fin assembly and a positioning seat; The airflow guide fin assembly includes an airflow guide fin body, which is a single plate structure. The airflow guide fin body has irregular protrusions and is a through structure with an irregular heat dissipation cavity inside. The two ends of the guide fin body are also provided with an air inlet and an exhaust outlet, and the air inlet and exhaust outlet are connected to the heat dissipation cavity structure of the guide fin body. The positioning seat is provided with a positioning groove that is adapted to the flow guide fin assembly, and the flow guide fin assembly is connected to the positioning seat by embedding in the positioning groove.

[0006] Preferably, the irregular protrusions on the surface of the guide fin body are distributed in a staggered manner without a fixed arrangement pattern, and multiple sets of turbulence-dispersing plates are arranged in an array on the inner wall of the heat dissipation cavity structure.

[0007] Preferably, each of the turbulence-dispersing plates has through holes. When cooling gas flows into the heat dissipation cavity structure from the air inlet of the guide fin body, the irregular through holes can guide the cooling gas and distribute it within the heat dissipation cavity structure.

[0008] Preferably, the multiple sets of the turbulence-dispersing plates form an integral structure with the end plug-in plate through the connecting rod. The plug-in plate is tightly fitted and plugged into the inner wall of the heat dissipation cavity structure of the guide fin body to achieve filling of the heat dissipation cavity structure.

[0009] Preferably, the end of the connector plate has an auxiliary protrusion extending outward, which facilitates the subsequent removal of the connector plate.

[0010] Preferably, each of the four corners of the guide fin body is provided with a hinge positioning plate, the hinge positioning plate is provided with a positioning hole, and the air inlet and the exhaust outlet are respectively integrated with the left and right sets of hinge positioning plates on the same side.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By adopting a single-plate structure with irregular protrusions on the guide fin body, the traditional flat guide fins break away from the single contact form. The staggered and irregularly distributed protrusions can change the flow direction and speed distribution of hot air from multiple angles and directions, causing the hot air to form a complex turbulent state inside the dryer. At the same time, the irregular heat dissipation cavity structure inside the guide fin body, combined with the array of turbulence-dispersing plates and through-hole design, provides an efficient guide path for the cooling gas, allowing the cooling gas to be distributed within the heat dissipation cavity and quickly remove the heat accumulated by the guide fins during high-temperature operation. This effectively prevents the fins from aging and deforming due to high temperatures, thus extending their service life. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a guide fin structure in a dryer, including a guide fin assembly 1 and a positioning seat 2. The guide fin assembly 1 includes a guide fin body 11, which is a single plate structure. The guide fin body 11 has irregular protrusions 111 and is a through structure with an irregular heat dissipation cavity structure 12 inside. The guide fin body 11 also has an air inlet 13 and an exhaust outlet 131 at both ends, which are connected to the heat dissipation cavity structure 12 of the guide fin body 11. The positioning seat 2 has a positioning groove that matches the guide fin assembly 1, and the guide fin assembly 1 is connected to the positioning seat 2 by embedding in the positioning groove.

[0019] By adopting a single-plate structure and setting irregular protrusions 111 in the guide fin body 11, the single contact form of traditional flat guide fins is broken. The staggered and irregularly distributed protrusions can change the flow direction and speed distribution of hot air from multiple angles and directions, causing the hot air to form a complex turbulent state inside the dryer. At the same time, the irregular heat dissipation cavity structure 12 inside the guide fin body 11, together with the array of turbulence separators 15 and through holes 151, provides an efficient flow path for the cooling gas, allowing the cooling gas to be distributed in the heat dissipation cavity and quickly remove the heat accumulated by the guide fin body 11 during high-temperature operation. This effectively prevents the guide fin body 11 from aging and deforming due to high temperature and extends its service life.

[0020] Please see Figures 1 to 4 The irregular protrusions 111 on the surface of the guide fin body 11 are distributed in a staggered manner without a fixed arrangement pattern, and multiple sets of turbulence partition plates 15 arranged in an array are provided on the inner wall of the heat dissipation cavity structure 12.

[0021] Please see Figures 1 to 4 Each set of turbulence separators 15 has through holes 151. When cooling gas flows into the heat dissipation cavity structure 12 from the air inlet 13 of the guide fin body 11, the irregular through holes 151 can guide the cooling gas and distribute it in the heat dissipation cavity structure 12.

[0022] Please see Figures 1 to 4Multiple sets of turbulence-dispersing plates 15 are integrated with the end plug-in plate 16 via connecting rod 17. The plug-in plate 16 is tightly fitted and plugged into the inner wall of the heat dissipation cavity structure 12 of the guide fin body 11 to fill the heat dissipation cavity structure 12. The end of the plug-in plate 16 extends outward with an auxiliary protrusion 161, which facilitates the subsequent removal of the plug-in plate 16.

[0023] Please see Figures 1 to 4 Each of the four corners of the guide fin body 11 is provided with a hinge positioning plate 14, and the hinge positioning plate 14 is provided with positioning holes. Furthermore, the air inlet 13 and the exhaust port 131 are integrated with the left and right sets of hinge positioning plates 14 on the same side. By providing hinge positioning plates 14 at the four corners of the guide fin body 11, the guide fin assembly 1 is positioned and fixed from multiple directions, which disperses the stress points during installation and avoids structural instability problems that may be caused by single-point stress.

[0024] When the drying process is completed and the guide fin body 11 needs to be cooled, the cooling gas source is connected to the air inlet 13 through a pipe. The cooling gas flows into the heat dissipation cavity structure 12. After entering the heat dissipation cavity structure 12, the cooling gas passes through the irregular through holes 151 on the turbulence partition 15. The irregular through holes 151 adjust the flow direction of the cooling gas. Together with the array arrangement of the turbulence partition 15, the cooling gas is evenly distributed in the heat dissipation cavity structure 12 and fully contacts the inner wall of the guide fin body 11 for heat exchange. The cooling gas carries away the heat accumulated in the guide fin body 11 due to high-temperature operation. After heat exchange, the cooling gas carries the heat and is discharged from the exhaust port 131, completing the heat dissipation process. When the temperature of the guide fin body 11 drops to a safe range, the cooling gas is stopped. If it is necessary to clean or repair the inside of the heat dissipation cavity structure 12 later, the integrated structure consisting of the turbulence separator 15 and the plug-in plate 16 can be pulled out from the heat dissipation cavity structure 12 by pulling the auxiliary protrusion 161 at the end of the plug-in plate 16, so as to carry out maintenance operations conveniently and quickly.
