Description

Technical Field

[0001] This utility model relates to the technical field of milk powder processing equipment, specifically a powder spraying tower anti-clogging device for milk powder production. Background Technology

[0002] In the milk powder production process, the concentrated milk is dried in a spray drying tower, collected and bagged to become milk powder. During the spray drying process, the milk powder will stick to the tower wall. Under the heating of the drying device inside the tower, the milk powder stuck to the wall will not only deteriorate, but also narrow the outlet of the spray drying tower, which will then cause blockage of the outlet.

[0003] A search revealed that Chinese patent CN212813957U discloses an anti-clogging device for a spray coating tower used in milk powder production. The device includes a motor, a mounting box, a rotating shaft, multiple mounting rods, multiple scrapers, and multiple connecting plates. The mounting box is located in the middle of the spray coating tower's outlet and is fixedly connected to the tower via multiple mounting rods. A vertically mounted motor is fixed inside the mounting box, and the motor's output shaft is coaxially fixed to the rotating shaft. Multiple connecting plates are fixed to the rotating shaft along its circumference. This device utilizes the motor's output to drive the rotating shaft within the spray coating tower. The scraper removes milk powder from the inner wall of the spray tower to prevent milk powder residue and blockage of the outlet. However, in practical applications, this structure still has some shortcomings. For example, since the scraper is located inside the spray tower tank, the scraped material tends to accumulate at the lower outlet of the tank, which is relatively narrow, making the anti-clogging effect less than ideal. Secondly, the drive motor for scraping is installed inside the tower, making it susceptible to temperature fluctuations, reducing its lifespan, and making subsequent replacement and maintenance relatively difficult. Therefore, this paper proposes an anti-clogging device for spray towers used in milk powder production to address these issues. Utility Model Content

[0019] 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 scope of protection of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses an anti-clogging device for a spray tower used in milk powder production. (Refer to...) Figures 1-4 A powder spraying tower anti-clogging device for milk powder production includes a base frame 1, a powder spraying tower tank 2 fixedly installed on the upper end of the base frame 1, an installation shell 7 provided on the inner side of the powder spraying tower tank 2, a first support pipe 5 and a second support pipe 6 fixedly installed on the outer side of the installation shell 7, the other end of the second support pipe 6 being fixedly installed to the inner wall of the powder spraying tower tank 2, the other end of the first support pipe 5 penetrating through the inner wall of the powder spraying tower tank 2, and a scraping mechanism 3 provided on the inner side of the installation shell 7.

[0022] The scraping mechanism 3 includes a shaft 304, which is rotatably connected to the inside of the mounting housing 7. An upper scraper 303, a lower scraper 305, and a spiral blade 306 are fixedly mounted on the outside of the shaft 304. A first bevel gear 307 is fixedly mounted on the outside of the shaft 304. A rotating rod 302 is fixedly mounted on the inside of the first support tube 5. One end of the rotating rod 302 extends into the mounting housing 7 and a second bevel gear 308 is fixedly mounted thereon. The first bevel gear 307 and the second bevel gear 308 are meshed. A motor 301 is movably mounted on the base frame 1 via a mounting seat 4. The output end of the motor 301 is movably mounted to the other end of the rotating rod 302 via a coupling. The operation of the motor 301 causes its output end to drive the rotating rod 302. The first support tube 5 rotates within the shaft, while the rotating rod 302 rotates by the second bevel gear 308 at its end meshing with the first bevel gear 307 inside the mounting housing 7. This also allows the shaft 304 connected to the first bevel gear 307 to rotate within the mounting housing 7. The upper and lower ends of the shaft 304 are connected to the upper scraper 303, the lower scraper 305, and the spiral blade 306, respectively, ensuring smooth material discharge while scraping the powder spraying tower tank 2. The shaft 304 is limited to rotating within the mounting housing 7, and the two cannot be separated. Two bearings are installed inside the first support tube 5, and the rotating rod 302 rotates within the first support tube 5 through the bearings. The rotating rod 302 is connected to the inner ring of the bearing, and the two cannot be separated, which ensures the stability of the rotation of the rotating rod 302.

[0023] Mounting base 4 includes a base 401, which is fixedly mounted on the upper end of the base frame 1. A sliding plate 402 is slidably connected to the upper end of the base 401. A connecting seat 404 is fixedly mounted on the lower end of the motor 301. The motor 301 is movably mounted via the connecting seat 404 and the sliding plate 402. One side of the sliding plate 402 is movably mounted to the base 401 via a hand-tightening bolt 403. By directly mounting the connecting seat 404 of the motor 301 onto the sliding plate 402, the sliding plate 402 is pushed towards the coupling of the rotating rod 302 to connect. Finally, the sliding plate 402 is secured by the hand-tightening bolt 403. The 03 fixing mechanism allows for convenient and quick disassembly and maintenance of the motor 301. Current installation methods require alignment and adjustment of the coupling on the output shaft of the motor 301 and the coupling on the rotating rod 302, followed by alignment and adjustment of the mounting holes on the motor 301 connecting seat 404, and finally connection and fixing. This is cumbersome. This structure, however, allows for direct fixing of the motor 301, followed by fixing via a movable coupling on the rotating rod 302, significantly improving the efficiency of disassembly and assembly of the motor 301. The movable plate also has mounting holes for the connecting seat 404.

[0024] Reference Figure 4A fixing block 11 is fixedly installed on one side of the moving plate 402. A hand-tightening bolt 403 is located inside the fixing block 11. A limit groove 12 is symmetrically opened at the upper end of the base 401. The lower end of the moving plate 402 is slidably connected to the inner side of the limit groove 12. The fixing block 11 has a round hole in which the hand-tightening bolt 403 is placed. A screw hole is opened on the base 401 so that the moving plate 402 can be limited and fixed on the base 401 after it moves. The limit groove 12 on the base 401 has a T-shaped cross section, which allows the moving plate 402 to slide on the base 401.

[0025] Reference Figure 2 The upper scraper 303 is located above the mounting shell 7, and the lower scraper 305 is located below the mounting shell 7. The spiral blade 306 extends into the inner side of the discharge port of the powder spraying tower tank 2. The outer side of the upper scraper 303 is fixedly installed with a first reinforcing rod 8 and a second reinforcing rod 9, and the outer side of the lower scraper 305 is fixedly installed with a third reinforcing rod 10. Through the cooperation of the upper scraper 303 and the lower scraper 305, the powder inside the powder spraying tower tank 2 can be scraped off. When the shaft 304 rotates, the lower end drives the spiral blade 306 to rotate at the discharge port of the powder spraying tower tank 2, which can facilitate material discharge and effectively prevent blockage. The first reinforcing rod 8 and the second reinforcing rod 9 on the upper scraper 303 can ensure the strength of the scraper on the side of the upper scraper 303. The third reinforcing rod 10 between the lower scraper 305 and the shaft 304 can ensure the strength of the lower scraper 305.

[0026] Working principle: During use, when scraping the powder from the inner wall of the powder spraying tower tank 2, simply start the motor 301, so that the output end of the motor 301 drives the rotating rod 302 to rotate in the first support tube 5. The rotation of the rotating rod 302 utilizes the second bevel gear 308 at its end to mesh with the first bevel gear 307 in the mounting housing 7, which also allows the shaft 304 connected to the first bevel gear 307 to rotate in the mounting housing 7. The upper and lower ends of the shaft 304 are respectively connected to the upper scraper 303, the lower scraper 305, and the spiral blade 306, ensuring smooth material discharge while scraping the powder from the powder spraying tower tank 2.

[0027] When installing the motor 301 of the scraping mechanism 3, the connecting seat 404 of the motor 301 is directly installed on the moving plate 402, the moving plate 402 is pushed to move towards the coupling of the rotating rod 302 to make it connected, and finally the moving plate 402 is fixed by the hand-tightening bolt 403.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
