Description

Technical Field

[0001] This utility model relates to the field of porcine hemoglobin powder production technology, and in particular to a spray drying tower for porcine hemoglobin powder with a uniform airflow distribution structure. Background Technology

[0002] The porcine blood globulin powder spray drying tower is a specialized device used to atomize porcine blood globulin powder slurry and bring it into full contact with hot air to rapidly evaporate moisture and obtain dry powder.

[0003] However, in actual use, the warm air entering the drying tower through the curved pipe in traditional spray drying towers is easily unevenly distributed due to the inertia of the airflow, which weakens the drying effect. Secondly, the filter screen in the slurry filter of the feeding mechanism of traditional spray drying towers is usually fixed. After a period of use, impurities adhere to the filter screen, making cleaning or replacement extremely inconvenient and reducing the maintainability and efficiency of the equipment. In addition, the slurry in traditional towers needs to be further crushed by downstream equipment after drying to achieve the ideal particle size. Even if some spray drying towers have added crushing structures to reduce the production cycle and cost, they are mostly single crushing blades installed at the bottom discharge port, which not only easily cause blockages but also have problems such as local deposition and uneven crushing, making it difficult to guarantee product quality.

[0004] Prior art 1 (Chinese patent application number CN202121944022.5, application date 2021-08-18) discloses a uniform airflow distribution structure at the inlet of a spray drying tower and a spray drying system. The first elbow is an arc-shaped bent pipe structure with a first lower inlet and a first upper outlet. Multiple first arc-shaped guide plates are arranged inside the first elbow at intervals along the radial direction of the arc-shaped bent pipe structure. The second elbow is also an arc-shaped bent pipe structure with a second lower outlet and a second upper inlet. Multiple second arc-shaped guide plates are arranged inside the second elbow at intervals along the radial direction of the arc-shaped bent pipe structure. The connecting pipe has a first connecting end and a second connecting end. The first connecting end is connected to the first upper outlet, and the second connecting end is connected to the second upper inlet, so that the flue gas is evenly distributed at the outlet.

[0005] Prior art 2 (Chinese patent application number CN202323205775.6, application date 2023-11-27) discloses a spray drying tower and a drying system. A crushing device is installed inside the drying tower body. The drying tower body includes a drying chamber, a discharge section and a material cylinder connected in sequence. Both the drying chamber and the material cylinder are cylindrical structures. The discharge section has a structure that is wider at the top and narrower at the bottom. A first discharge port is provided at the bottom of the material cylinder, and a first air outlet is opened on the side of the discharge section. The crushing device includes a stirring shaft and a crushing blade connected to the stirring shaft. The crushing blade is located at the discharge section. The drying system includes the spray drying tower as described above. A crushing unit is added to the existing spray drying tower. The spray drying and crushing unit work together to complete the spray drying process of the slurry and crush the powder. This not only reduces the particle size of the material, but also saves time and improves efficiency by eliminating the airflow crushing section. Utility Model Content

[0020] The airflow distribution assembly 5 includes a heater 51 mounted on the mounting bracket 2 4. The heater 51 heats the airflow to provide the necessary heat energy for the drying process. A bend 52 is provided on the top of the heater 51, which guides the heated airflow into the connecting pipe 55. At the same time, an internal arc-shaped guide plate guides the airflow to ensure uniform flow. A top cover 53 is provided on the top of the drying chamber 3, which closes the top of the drying chamber 3. A bend 54 is provided on the top cover 53. A connecting pipe 55 is provided between the bend 52 and the bend 54, connecting the bend 52 and the bend 54. Pipe 2 54 allows for smooth airflow transmission between the two pipes. Both bend 1 52 and bend 2 54 are equipped with arc-shaped guide plates. Bend 2 54 guides the airflow into the hot air distributor 56.

[0021] The feeding assembly 7 includes a slurry filter 71 mounted on the mounting frame 6. The slurry filter 71 filters the porcine blood globulin powder slurry to remove impurities. The slurry filter 71 has a mounting frame 72 inside, which provides a mounting base for the filter screen 73. The filter screen 73 filters the slurry entering the slurry filter 71 to ensure the quality of the slurry. A pair of connectors 74 are symmetrically arranged on both sides of the filter screen 73. The connectors 74 provide a mounting base for the flip-up buckle 75 and allow the flip-up buckle 75 to rotate around it. Both connectors 74 are equipped with flip-up buckles 75. The flip-up buckles 75 cooperate with the mounting sleeve 77, the disc 78, the spring 710, the long rod 79, and the knob 711 to realize the installation and removal of the filter screen 73. Both flip-up buckles 75 are provided with elongated holes 76 for the long rod 79 and the knob 711 to pass through, for locking or unlocking the flip-up buckles 75.

[0022] Mounting sleeves 77 are provided on both sides of the mounting frame 72 at positions corresponding to the flip-up buckles 75. Each mounting sleeve 77 contains a disc 78, which provides a mounting base for the spring 710 and the long rod 79. A spring 710 is installed between the disc 78 and the inner wall of the mounting sleeve 77, providing elasticity to the disc 78 so that the limiting block 712 is firmly engaged in the limiting groove 713 for locking. A long rod 79 is installed on the disc 78, passing through the mounting sleeve 77. When the operator operates the knob 711, the long rod 79... Power is transmitted to the disc 78 and the spring 710. A knob 711 is provided at one end of the long rod 79. The knob 711 makes it easy for the operator to pull up and rotate the long rod 79 to lock and unlock the flip buckle 75. A pair of limit blocks 712 are symmetrically arranged on one side of the knob 711. Limit grooves 713 corresponding to the limit blocks 712 are provided on both sides of the flip buckle 75 of the elongated hole 76. The limit blocks 712 cooperate with the limit grooves 713 on the flip buckle 75 to lock the flip buckle 75, thereby ensuring that the filter screen 73 is securely installed on the mounting frame 72.

[0023] A cover plate 714 is provided on one side of the slurry filter 71. The cover plate 714 can be opened to maintain or replace the filter screen 73. A feed pipe 715 is provided on the cover plate 714. The porcine blood globulin powder slurry enters the slurry filter 71 through the feed pipe 715. A feed pump 716 is provided on the mounting bracket 6 on one side of the slurry filter 71. A pipe is provided between the slurry filter 71 and the feed pump 716. A conveying pipe 717 is provided on one side of the feed pump 716. The conveying pipe 717 passes through the drying chamber 3. The feed pump 716 draws out the filtered slurry through the pipe and then conveys it to the atomizer 718 through the conveying pipe 717. An atomizer 718 is provided at the head of the conveying pipe 717. A nozzle 719 is provided on the atomizer 718. The atomizer 718 atomizes the slurry into fine droplets through the nozzle 719 and sprays them into the drying chamber 3.

[0024] The crushing assembly 8 includes a pair of symmetrically arranged mounting seats 81 on both sides of the bottom of the drying chamber 3. The mounting seats 81 provide a mounting base for the rotating shaft 82. The rotating shaft 82 is mounted on both mounting seats 81 through bearing seats. Both rotating shafts 82 pass through the drying chamber 3. A pair of crushing blades 83 are fitted on each of the two rotating shafts 82. A sprocket 84 is fitted on the bottom of each of the two rotating shafts 82. A transmission chain 85 is arranged between the two sprockets 84. A motor 86 is mounted on the base 1 directly below the right rotating shaft 82. The transmission end of the motor 86 is connected to the bottom of the rotating shaft 82. The motor 86 drives the right rotating shaft 82 and the sprocket 84 to rotate. The right sprocket 84 transmits power to the left sprocket 84 through the transmission chain 85, so that the two rotating shafts 82 rotate synchronously. The rotation of the rotating shafts 82 drives the crushing blades 83 to rotate, crushing the dried material and ensuring that the material particles are uniform.

[0025] In operation, the operator first activates the airflow distribution assembly 5. The heater 51 heats the airflow. The heated airflow passes sequentially through bend 1 52, connecting pipe 55, and bend 2 54. Arc-shaped guide plates within bend 1 52 and bend 2 54 guide the airflow, ensuring uniform flow. The airflow then enters the hot air distributor 56, which distributes the hot air evenly into the drying chamber 3 through several nozzles 1 57. Next, the operator activates the feed pump 716 in the feeding assembly 7. The porcine blood globulin powder slurry enters the slurry filter 71 through the feed pipe 715. The slurry is filtered through the filter screen 73 in the slurry filter 71 to remove impurities. The filtered slurry is then pumped out through a pipe by the feed pump 716 and transported to the atomizer 718 through the conveying pipe 717. The atomizer 718 atomizes the slurry into fine droplets through nozzle 2 719 and sprays them into the atomizer. Inside the drying chamber 3, the atomized slurry droplets come into full contact with the hot air, causing the moisture in the slurry droplets to evaporate rapidly, thus achieving drying. The dried material falls under the influence of gravity. To ensure that the dried material achieves the desired particle size, the operator can activate the crushing assembly 8, which drives the right-side rotating shaft 82 and sprocket 84 to rotate via the motor 86. The right-side sprocket 84 transmits power to the left-side sprocket 84 through the transmission chain 85, causing the two rotating shafts 82 to rotate synchronously. The rotating shafts 82 drive the crushing blades 83 to rotate. The two upper crushing blades 83 can perform preliminary crushing of the material, while the lower crushing blades 83 can further crush the falling material, ensuring uniform particle size and preventing material from being missed during crushing by the upper crushing blades 83, which could cause localized material deposition. Finally, the dried and crushed material is discharged from the bottom of the drying chamber 3, completing the entire spray drying process of porcine blood cell protein powder.

[0026] After a period of use, the operator can maintain or replace the filter screen 73 inside the slurry filter 71. First, shut down the entire device, then open the cover plate 714 on one side of the slurry filter 71. Next, pull up and rotate the knob 711 to move the long rod 79 and the disc 78 within the mounting sleeve 77, compressing the spring 710. At this time, the limit block 712 exits from the limit groove 713, and the knob 711 is parallel to the elongated hole 76, releasing the lock on the flip buckle 75. Then, the operator can flip the flip buckle 75 to release the connection between the filter screen 73 and the mounting frame 72, and then remove the filter screen 73 from the slurry filter 71. When maintaining or replacing the filter screen 73, and reinstalling the filter screen 73, first align the filter screen 73 with the mounting frame 72 and insert it. Then, flip the flip buckle 75 so that the knob 711 and the long rod 79 pass through the elongated hole 76 on the flip buckle 75. Then, pull up and rotate the knob 711, align the limiting block 712 on one side of the knob 711 with the limiting groove 713 on the flip buckle 75 and insert it. Under the action of the spring force 710, the disc 78 drives the long rod 79 to move, so that the limiting block 712 is firmly locked into the limiting groove 713, thus achieving a stable installation of the filter screen 73. After the operator reinstalls the cover plate 714, the spray drying tower can be restarted.
