Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to an anti-clogging device for the atomizing nozzle of a spray granulator. Background Technology

[0002] A spray granulator is a device used to convert liquid materials into granules. It is widely used in the pharmaceutical, fertilizer, food, and chemical industries. Its principle is to atomize liquid solutions or suspensions into small droplets through a spray system, and then use hot air to rapidly dry the droplets, forming uniform granules. This equipment has advantages such as adjustable particle size, high production efficiency, and low energy consumption. Spray granulators are suitable for producing pharmaceutical granules, fertilizer granules, etc., ensuring stable product quality and uniform particle size distribution.

[0003] The atomizing nozzle of a spray granulator is a key component that atomizes liquid materials into tiny droplets. It refines the liquid through high pressure or high speed rotation to produce a uniform mist spray. The design of the atomizing nozzle directly affects the size, distribution, and drying effect of the particles. Therefore, it plays a vital role in the spray granulation process. A suitable nozzle can improve particle quality and ensure production efficiency and product consistency.

[0004] Existing spray granulators produce uniform mist spray through their atomizing nozzles. However, after a period of use, the nozzles become clogged due to material deposition or agglomeration, affecting the normal operation of atomization. To address this issue, a clog prevention device for the atomizing nozzles of spray granulators is proposed. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of an anti-clogging device for the atomizing nozzle of a spray granulator, comprising a connecting pipe 1 and a water pipe 2. A quick-release assembly is installed inside the connecting pipe 1, and the end of the water pipe 2 is located within the quick-release assembly. A connecting plate 3 is fixedly connected to the bottom of the connecting pipe 1, and a rotary positioning assembly is installed at the bottom of the connecting plate 3. A multi-stage nozzle 4 is located at the bottom of the rotary positioning assembly. The quick-release assembly includes a docking plate 5, which is fixedly connected inside the connecting pipe 1. The connecting pipe 1 is used to connect various structures. A fixing plate 6 is fixedly connected inside the connecting pipe 1, and a spring telescopic rod 7 is installed on the top of the fixing plate 6. A pressure plate 8 is fixedly connected to the end of the spring telescopic rod 7. The pressure applied to the pressure plate 8 by the spring telescopic rod 7 causes it to move upward. A fixing block 9 is fixedly connected to the end of the water pipe 2. A sliding groove 10 is formed inside the docking plate 5, and the fixing block 9 is slidably connected inside the sliding groove 10, entering the docking plate 5 from the sliding groove 10. The docking plate 5 has a fixed slot 11 inside. The fixed block 9 is engaged with the fixed slot 11. The pressure plate 8 moves upward and inserts the fixed block 9 into the fixed slot 11.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The rotary positioning assembly includes a rotary plate 13, which is rotatably connected to the bottom of a connecting plate 3. The rotary plate 13 connects various structures. A multi-stage nozzle 4 is located at the bottom of the rotary plate 13. Rotating the rotary plate 13 causes the multi-stage nozzle 4 to rotate as well. A tension spring telescopic rod 14 is fixedly connected inside the rotary plate 13, with its end fixedly connected to the inside of the connecting plate 3. The pressure applied to the rotary plate 13 by the tension spring telescopic rod 14 causes it to move towards the connecting plate 3. A semi-circular locking block 15 is fixedly connected to the side of the rotary plate 13. A semi-circular locking groove 16 is formed on the side of the connecting plate 3. The semi-circular locking block 15 and the semi-circular locking groove 16 engage with each other. When the rotary plate 13 moves towards the connecting plate 3, the semi-circular locking block 15 engages with the semi-circular locking groove 16.

[0034] Reference Figure 2 and Figure 3 A baffle 17 is fixedly connected to the end of the tension spring telescopic rod 14. The baffle 17 is fixedly connected to the side of the connecting plate 3, preventing the tension spring telescopic rod 14 from detaching from the connecting plate 3. A protective tube 18 is fixedly connected inside the rotating plate 13. The protective tube 18 is slidably connected inside the connecting plate 3, protecting the tension spring telescopic rod 14 inside and supporting the rotation of the rotating plate 13. An isolation tube 12 is fixedly connected to the end of the water pipe 2. The isolation tube 12 is located inside the docking plate 5, the fixed plate 6, the spring telescopic rod 7, and the pressure plate 8. By setting the isolation tube 12, the liquid flows out from inside the isolation tube 12 and will not come into contact with the docking plate 5, the fixed plate 6, the spring telescopic rod 7, and the pressure plate 8, thus preventing corrosion.

[0035] Working principle: Move the connecting pipe 1 upwards, and the fixing block 9 will disengage from the fixing slot 11 of the connecting plate 5. Then rotate the connecting pipe 1 to slide the fixing block 9 out of the sliding groove 10 from the connecting plate 5. Remove the multi-stage nozzle 4 and clean it to prevent clogging and affecting atomization. After cleaning, slide the fixing block 9 from the sliding groove 10 into the connecting plate 5. Then rotate the connecting pipe 1. The pressure generated by the cooperation of the fixing plate 6 and the spring telescopic rod 7 will cause the pressure plate 8 to be forcefully engaged and the fixing block 9 into the fixing slot 11. Reinstall the multi-stage nozzle 4.

[0036] The control plate 13 rotates with the multi-stage nozzles 4, and the appropriate nozzle is rotated to be directly below the connecting pipe 1. The tension applied by the tension spring telescopic rod 14 causes the rotating plate 13 to move upward, and the semi-circular locking block 15 is locked into the semi-circular locking groove 16 to fix the position of the appropriate nozzle. This allows for the switching of different specifications of nozzles, enabling the device to adapt to the spraying requirements of different materials and improve the applicability of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
