Description

Technical Field

[0001] This utility model relates to the field of spray drying technology, specifically a hot air distribution and equalization device for spray drying. Background Technology

[0002] Spray drying technology can quickly convert liquid materials into powder and is widely used in food, medicine, new energy materials and other fields. The uniformity of hot air distribution is the core factor that determines the efficiency and product quality of spray drying, which makes the hot air distribution and equalization device a key component of the spray drying system. In practical applications, most devices use fixed baffles and a single flow guide structure, which can only achieve preliminary flow equalization for specific materials. When switching materials, the hot air velocity and distribution pattern cannot be flexibly adjusted, resulting in a loss of equipment adaptability. Secondly, when hot air enters from one side of the pipeline, it will continuously impact the other side, resulting in excessively high hot air velocity on the air inlet side of the main cylinder and excessively low velocity on the air outlet side, and even forming dead zones where airflow stagnates in the corners of the cylinder wall, thereby reducing the quality of product production. To address the above problems, the inventors have proposed a hot air distribution and equalization device for spray drying to solve these issues. Utility Model Content

[0003] To address the issues of insufficient equipment compatibility and uneven hot air distribution, the purpose of this invention is to provide a hot air distribution and equalization device for spray drying.

Multiple guide plates arranged in a ring are slidably installed inside the stop disc, and a stop pin is fixedly installed at the bottom of each guide plate. Two symmetrically distributed support columns are fixedly installed inside the stop column frame, and the sliding disc rotates along the inside of the two support columns. A guide groove is opened inside the stop disc to slide and cooperate with the multiple guide plates, and the multiple guide plates slide tightly against the inner wall of the guide groove. A positioning groove is opened inside the sliding disc to slide and cooperate with the stop pin, and the stop pin slides against the inner wall of the positioning groove. An electric cylinder is rotatably installed inside the rotating frame, and a connecting rod is fixedly installed at the output end of the electric cylinder. The connecting rod is rotatably connected to the protrusion of the sliding disc. An atomizer is fixedly installed in the middle of the sliding disc and the stop disc.

[0006] Preferably, the wind vane full-circumference rotation device includes a cylindrical frame, which is fixedly installed on the top of the stop column frame. A servo motor is fixedly installed on the inner wall of the cylindrical frame. A transmission rod is driven by the servo motor. A drive gear is fixedly installed in the middle of the outer wall of the transmission rod. An annular rack that meshes with the drive gear is fixedly installed on the outer wall of the rotating frame. The other end of the transmission rod is rotatably connected to the inner wall of the stop column frame. The stop disc is fixedly connected to two support columns.

[0007] Preferably, a blower is provided on one side of the outer wall of the hot air distribution main cylinder, and a hot air delivery pipeline assembly is connected to the output end of the blower, and the other end of the hot air delivery pipeline assembly is connected to the atomizer.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

This utility model sets up a full-circumference rotation device for the air vane, which starts the servo motor and drives the transmission rod and the drive gear to rotate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0013] like Figure 1-9 As shown, this utility model provides a hot air distribution and equalization device for spray drying, including a hot air distribution main cylinder 1, a baffle plate adjustment device 2 is provided at the top of the hot air distribution main cylinder 1, a wind plate full-circumference rotation device 3 is provided at the top of the baffle plate adjustment device 2, and a collection cylinder 4 is provided directly below the bottom of the hot air distribution main cylinder 1. The baffle adjustment device 2 includes a stop column frame 21, which is fixedly installed on the top of the hot air distribution main cylinder 1. A rotating frame 22 is rotatably installed inside the stop column frame 21. A sliding disc 23 is provided inside the rotating frame 22. A stop disc 24 is fixedly installed at the bottom of the sliding disc 23. Multiple guide plates 26 arranged in a ring are slidably installed inside the stop disc 24. A stop pin 27 is fixedly installed at the bottom of each of the multiple guide plates 26. Two symmetrically distributed support columns 29 are fixedly installed inside the stop column frame 21, and the sliding disc 23 rotates along the inside of the two support columns 29.

[0014] By adopting the above technical solution, when the sliding disc 23 rotates along the inside of the two support columns 29, it simultaneously drives multiple guide plates 26 to slide along the inside of the stop disc 24, which facilitates flexible adjustment of the position of multiple guide plates 26, thereby accurately controlling the airflow angle of the hot air and making the device adaptable to different drying conditions.

[0015] The wind vane full-circumference rotation device 3 includes a cylindrical frame 31, which is fixedly installed on the top of the stop column frame 21. A servo motor 32 is fixedly installed on the inner wall of the cylindrical frame 31. A transmission rod 33 is installed on the drive end of the servo motor 32. A drive gear 34 is fixedly installed in the middle of the outer wall of the transmission rod 33. A ring rack 35 that meshes with the drive gear 34 is fixedly installed on the outer wall of the rotating frame 22.

[0016] By adopting the above technical solution, the servo motor 32 synchronously drives the transmission rod 33 and the drive gear 34 to rotate. Because the drive gear 34 meshes with the rotating frame 22, it synchronously drives the guide plate 26 inside the rotating frame 22 to make a circular motion, so as to achieve more uniform hot air entering the subsequent drying process.

[0017] The stop disc 24 has a guide groove 25 inside which it slides in cooperation with multiple guide plates 26, and the multiple guide plates 26 slide closely along the inner wall of the guide groove 25.

[0018] By adopting the above technical solution, the guide groove 25 provides a sliding path for the guide plate 26, strictly restricts the sliding direction of the guide plate 26, and avoids deviation or skew during the adjustment process.

[0019] The sliding disc 23 has a positioning groove 28 inside, which is used to slide with the stop pin 27, and the stop pin 27 slides along the inner wall of the positioning groove 28.

[0020] By adopting the above technical solution, the stop pin 27 slides along the inner wall of the positioning groove 28, avoiding deviation or skew during the sliding process, and accurately limiting the movement trajectory of the stop pin 27.

[0021] An electric cylinder 210 is rotatably mounted inside the rotating frame 22. A connecting rod 211 is fixedly mounted on the output end of the electric cylinder 210, and the connecting rod 211 is rotatably connected to the protrusion of the sliding disc 23.

[0022] By adopting the above technical solution, when the electric cylinder 210 starts, the driving linkage 211 drives the sliding disc 23 to rotate, so that multiple guide plates 26 slide along the positioning groove 28 opened inside the stop disc 24, and the guide plates 26 are adjusted according to the drying hot air flow rate of different materials.

[0023] The other end of the transmission rod 33 is rotatably connected to the inner wall of the stop column frame 21, and the stop disc 24 is fixedly connected to the two support columns 29.

[0024] By adopting the above technical solution, the transmission rod 33 is prevented from deviating during rotation, thus improving the stability of rotation adjustment.

[0025] An atomizer is fixedly installed in the middle of the sliding disc 23 and the stop disc 24.

[0026] By adopting the above technical solution, it is ensured that the droplets are always sprayed stably from the center position, avoiding the decrease in atomization accuracy caused by hot air washing of the nozzle.

[0027] A blower 5 is provided on one side of the outer wall of the hot air distribution main cylinder 1. The output end of the blower 5 is connected to a hot air conveying pipeline assembly 6, and the other end of the hot air conveying pipeline assembly 6 is connected to the rotating frame 22.

[0028] By adopting the above technical solution, the rotating frame 22 moves circumferentially under the drive of the wind plate full-circumference rotation device 3. After the hot air directly enters the rotating frame 22, it will be evenly distributed into the hot air distribution main cylinder 1 by multiple guide plates 26.

[0029] Working principle: In actual application, the blower 5 starts and delivers hot air to the inside of the hot air distribution main cylinder 1 through the hot air conveying pipeline assembly 6. Then, the air plate full-circumference rotation device 3 evenly disperses the hot air in the circumference. At the same time, the atomizer in the middle of the hot air distribution main cylinder 1 sprays atomized material, which comes into full contact with the hot air to complete the drying process. The dried material eventually settles under the airflow and is collected in the collection cylinder 4. When it is necessary to adapt to the drying of different materials, combine Figure 3 , Figure 4 and Figure 5 As shown, when the electric cylinder 210 is started, its output end drives the connecting rod 211 to slide backward, thereby driving the sliding disc 23 to rotate smoothly inside the two support columns 29. During the rotation, the stop pins 27 at the bottom of the multiple guide plates 26 slide closely along the positioning grooves 28 opened inside the sliding disc 23, and at the same time drive the guide plates 26 to slide synchronously along the guide grooves 25 inside the stop disc 24. Under the dual guidance constraint of the positioning grooves 28 and the guide grooves 25, the angle of the multiple guide plates 26 can be precisely adjusted, thereby flexibly adapting to the drying of different materials. When it is necessary to achieve full circumference rotation of the air guide device, combined with Figure 8 , Figure 9 As shown, when the servo motor 32 starts, its drive end drives the transmission rod 33 to rotate. The drive gear 34, which is fixedly installed in the middle of the outer wall of the transmission rod 33, rotates synchronously. Since the drive gear 34 meshes with the ring rack 35 fixedly installed in the outer wall of the rotating frame 22, when the drive gear 34 rotates, it will synchronously drive the rotating frame 22 to rotate along the inside of the stop column frame 21, thereby making the hot air more evenly distributed inside the hot air distribution main cylinder 1.
