[0004] The purpose of this application is to provide an adjustable angle structure for the air inlet guide shroud of a spray dryer fan in order to solve the problems mentioned above.
[0005] The technical solution adopted in this application is as follows: an adjustable angle structure for the air inlet guide hood of a spray dryer fan, including a guide hood interface of the main body of the equipment, a fixed ring fixedly connected to the front of the guide hood interface, a through arc-shaped guide groove opened on the outer side of the fixed ring, a guide vane adjusting column slidably connected to the inner side of the arc-shaped guide groove, a guide vane fixedly connected to the inner side of the guide vane adjusting column, a guide vane fixing rotating column fixedly connected to the outer side of the guide vane, a guide vane fixing rotating column groove rotatably connected to the outer side of the guide vane adjusting column, and a guide vane adjusting column adjusting groove slidably connected to the outer side of the guide vane adjusting column.
[0006] By adopting the above technical solution, during the operation of the equipment, the guide shroud interface is placed into the air inlet. The limiting positioning block and the limiting positioning groove can prevent the equipment from rotating and position it. Then, by manually rotating the rotating adjusting ring, through the internal and external threads, the rotating adjusting ring can move forward or backward on the fixed ring. The rotation and movement of the rotating adjusting ring will drive the guide vane adjusting column to move within the arc-shaped guide groove through the internally opened guide vane adjusting column, which will drive the guide vane to rotate along the fixed rotating column of the guide vane. This allows for adjustment of the guide vane's inclination. The operation of this equipment can drive the rotation of the guide vane, and the inclination can be adjusted during equipment use, thereby optimizing the airflow distribution, improving the drying efficiency of the spray dryer, and closing the guide vane when the equipment is idle, thereby reducing dust entry and extending the service life of the equipment.
[0007] In a preferred embodiment, a guide vane fixing rotating column groove is provided on the inner side of the fixing ring, and a guide vane fixing rotating column is rotatably connected to the inner side of the guide vane fixing rotating column groove.
[0008] By adopting the above technical solution, the guide vanes can rotate stably, thereby maintaining the stable operation of the equipment when adjusting the guide vanes.
[0009] In a preferred embodiment, the outer side of the fixed ring is fixedly connected with an external thread, the outer side of the external thread is slidably connected with an internal thread, the outer side of the internal thread is fixedly connected with a rotating adjustment ring, and the inner side of the rotating adjustment ring is provided with a guide vane adjustment column adjustment groove.
[0010] By adopting the above technical solution, the guide vanes can be adjusted by rotating the rotating adjustment ring, thereby allowing for adjustment without stopping the machine and improving equipment efficiency.
[0011] In a preferred embodiment, a limiting ring is fixedly connected to the front of the fixing ring.
[0012] By adopting the above technical solution, the rotation adjustment ring can be prevented from disengaging, ensuring the normal operation of the equipment.
[0013] In a preferred embodiment, a limiting positioning block is fixedly connected to the outer side of the flow guide interface, and a limiting positioning groove is slidably connected to the outer side of the limiting positioning block.
[0014] By adopting the above technical solution, a stable connection between the equipment and the fan outlet can be guaranteed.
[0015] In a preferred embodiment, an air inlet is slidably connected to the outer side of the air guide shroud interface, and a limiting positioning groove is formed on the inner side of the air inlet.
[0016] By adopting the above technical solution, the equipment can be easily installed and disassembled, and maintenance can be convenient.
[0017] In a preferred embodiment, a fan is fixedly connected to the inner side of the air inlet.
[0018] By adopting the above technical solution, the equipment is driven to operate and draw air.
[0019] In a preferred embodiment, a guide vane fixing block is rotatably connected to the inner side of the guide vane.
[0020] By adopting the above technical solutions, the stable operation of the guide vanes is ensured.
[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0022] In this application, during the operation of the equipment, the guide shroud interface is placed into the air inlet. The limiting positioning block and the limiting positioning groove prevent the equipment from rotating, thus positioning the equipment. Then, by manually rotating the adjusting ring, which uses internal and external threads, the adjusting ring can move forward or backward around the fixed ring. The rotation of the adjusting ring, through the internally opened guide vane adjusting column adjustment groove, drives the guide vane adjusting column to move within the arc-shaped guide groove, causing the guide vane to rotate along the fixed rotating column. This allows for adjustment of the guide vane's inclination. The equipment can be easily adjusted by rotating the adjusting ring, and the cooperation between the adjusting ring and the external thread ensures the guide vane is fixed, ensuring stable operation. The rotation of the guide vane allows for adjustment of the inclination during use, optimizing airflow distribution and improving the drying efficiency of the spray dryer. Furthermore, when the equipment is idle, the guide vane can be closed, reducing dust entry and extending the equipment's lifespan. Attached Figure Description

A guide vane fixing rotating column groove 17 is rotatably connected to the outer side of the guide vane fixing rotating column 6. A guide vane adjusting column adjusting groove 11 is slidably connected to the outer side of the guide vane adjusting column 4.
[0033] Reference Figure 1-6 During operation, the guide shroud interface 1 is placed into the air inlet 15. The limiting positioning block 13 and the limiting positioning groove 14 prevent the equipment from rotating and position it. Then, by manually rotating the rotating adjusting ring 9, the internal thread 10 and the external thread 8 allow the rotating adjusting ring 9 to rotate forward or backward on the fixed ring 2. The rotation and movement of the rotating adjusting ring 9 will drive the guide vane adjusting column 4 to move within the arc-shaped guide groove 3 through the internal guide vane adjusting column adjusting groove 11. This will drive the guide vane 5 to rotate along the guide vane fixed rotating column 6, thereby adjusting the inclination of the guide vane 5. The operation of the equipment can be easily adjusted by rotating the adjusting ring 9. The cooperation between the rotating adjusting ring 9 and the external thread 8 can fix the guide vane 5, ensuring stable operation of the equipment. The guide vane 5 can be rotated 90 degrees, and the inclination can be adjusted during equipment use to optimize airflow distribution and improve the drying efficiency of the spray dryer. When the equipment is idle, the guide vane 5 can be closed to reduce dust entry and extend the service life of the equipment.
[0034] Reference Figure 1-3 The inner side of the fixed ring 2 is provided with a guide vane fixing and rotating column groove 17, and the guide vane fixing and rotating column 6 is rotatably connected to the inner side of the guide vane fixing and rotating column groove 17. This allows the guide vane 5 to rotate stably, thereby maintaining the stable operation of the equipment when adjusting the guide vane 5.
[0035] Reference Figure 1-5 The outer side of the fixed ring 2 is fixedly connected with an external thread 8, and the outer side of the external thread 8 is slidably connected with an internal thread 10. The outer side of the internal thread 10 is fixedly connected with a rotating adjusting ring 9, and the inner side of the rotating adjusting ring 9 is provided with a guide vane adjusting groove 11. The guide vane 5 can be adjusted by rotating the rotating adjusting ring 9, so that the adjustment can be carried out without stopping the machine, thereby improving the efficiency of the equipment.
[0036] Reference Figure 1-3 A limit ring 12 is fixedly connected to the front of the fixed ring 2. This prevents the rotating adjusting ring 9 from disengaging and ensures the normal operation of the equipment.
[0037] Reference Figure 1-2 A limiting positioning block 13 is fixedly connected to the outer side of the flow guide shroud interface 1, and a limiting positioning groove 14 is slidably connected to the outer side of the limiting positioning block 13. This ensures a stable connection between the equipment and the fan outlet.
[0038] Reference Figure 1-2 An air inlet 15 is slidably connected to the outer side of the air guide shroud interface 1, and a limiting positioning groove 14 is formed on the inner side of the air inlet 15. This facilitates the installation and disassembly of the equipment and makes maintenance convenient.
[0039] Reference Figure 1-2 A fan 16 is fixedly connected to the inside of the air inlet 15. It drives the equipment to operate and draw in air.
[0040] Reference Figure 1-4 A guide vane fixing block 7 is rotatably connected to the inner side of the guide vane 5 to ensure the stable operation of the guide vane 5.
[0041] The implementation principle of the embodiment of the adjustable angle guide shroud for the air inlet of the spray dryer in this application is as follows:
[0042] During operation, the air guide shroud interface 1 is placed into the air inlet 15. The limiting positioning block 13 and the limiting positioning groove 14 prevent the equipment from rotating and position it. Then, by manually rotating the rotating adjusting ring 9, the internal thread 10 and the external thread 8 allow the rotating adjusting ring 9 to rotate forward or backward on the fixed ring 2. The rotation and movement of the rotating adjusting ring 9 will drive the guide vane adjusting column 4 to move within the arc-shaped guide groove 3 through the internal guide vane adjusting column adjusting groove 11. This will drive the guide vane 5 to rotate along the guide vane fixed rotating column 6, thereby adjusting the inclination of the guide vane 5. The operation of the equipment can be easily adjusted by rotating the adjusting ring 9. The cooperation between the rotating adjusting ring 9 and the external thread 8 can fix the guide vane 5, ensuring stable operation of the equipment. The guide vane 5 can be rotated 90 degrees, and the inclination can be adjusted during equipment use to optimize airflow distribution and improve the drying efficiency of the spray dryer. When the equipment is idle, the guide vane 5 can be closed to reduce dust entry and extend the service life of the equipment.
