Description

Technical Field

[0001] This utility model relates to the field of chemical equipment manufacturing technology, specifically to a granulation device for ammonium chloride production. Background Technology

[0002] Ammonium chloride is an important chemical raw material, widely used in agriculture (providing nitrogen fertilizer) and industry (for battery manufacturing, electroplating, welding, etc.). Its production efficiency and product quality are crucial for meeting market demand and promoting the development of related industries. Granulation is a key step in ammonium chloride production, aiming to convert powdered ammonium chloride into granules with specific particle size and strength for easier storage, transportation, and use. Traditional ammonium chloride granulation equipment uses rapid drying, often with a drying zone directly below the granulation unit where the granulated ammonium chloride falls directly. However, freshly granulated ammonium chloride is not hard enough and is easily deformed by external forces. Deformation leads to uneven particle size in the final product, affecting physical properties such as solubility and flowability, reducing its effectiveness in various applications. For example, in agriculture, it can cause uneven fertilization and affect crop growth; it can also alter the internal structure of the granules, reducing their strength and making them more prone to breakage and dust generation during storage, transportation, and use, resulting in resource waste and harm to the environment and human health.

[0003] Therefore, there is an urgent need for a method that can achieve rapid drying while effectively preventing the deformation of freshly formed ammonium chloride from falling directly into the drying zone. Utility Model Content

[0026] Please see Figure 1-4 This embodiment provides a granulation device for ammonium chloride production, including a base 1, a drying oven 2, a first motor 3, a stirring rod 4, and a heating element 41.

[0027] The drying chamber 2 has an opening at the top, and a loading box 5 is welded to the opening. The side wall of the loading box 5 has a feed pipe 6. For easier feeding, the top of the feed pipe 6 is conical. The ammonium chloride material enters the loading box through the feed pipe 6. The top of the loading box 5 is penetrated by a cylinder 7 and welded together. The cylinder 7 drives the pressure plate 8 to squeeze the material downward. Under pressure, the material is squeezed out through the round hole of the forming plate 9 to form strips. The output end of the cylinder 7 is equipped with a pressure plate 8, and the opening is equipped with a forming plate 9. The bottom end of the forming plate 9 is equipped with a second motor 10. The output end of the second motor 10 is equipped with a cutting blade 11. The second motor 10 drives the cutting blade 11 to rotate at high speed, cutting the strip material into uniform particles. The particles fall into the drying chamber 2. The stirring rod 4 in the drying chamber 2 rotates under the drive of the first motor 3 to disperse the particles. At the same time, the heating tube 41 heats up to provide a drying heat source, accelerating the evaporation of moisture on the particle surface, and finally obtaining dry ammonium chloride particles.

[0028] The drying chamber 2 is located below the cutting blade 11 and is suspended by a net bag 13 via a connecting rope 12 arranged symmetrically on four sides. After the cutting blade 11 cuts the extruded strip-shaped ammonium chloride material into granules, the granules fall directly into the net bag 13 suspended below. The net bag 13 acts as a buffer to receive the granules. At the same time, the heating tube 41 heats up, which accelerates the drying of the granules falling into the net bag 13. The mesh structure of the net bag 13 also facilitates the uniform penetration of hot air into the granules.

[0029] like Figure 2 As shown, the net bag 13 is suspended by the four symmetrical connecting ropes 12, which can effectively disperse the impact force of the falling particles and avoid particle damage. At the same time, it ensures that the particles are evenly dispersed in the net bag 13, improving drying efficiency. Meanwhile, the stirring rod 4 in the drying box 2 rotates under the drive of the first motor 3 and heats up the heating tube 41 to dry the particles. This not only ensures that the newly formed ammonium chloride particles will not break due to falling from a height, but also achieves a better drying effect through secondary drying.

[0030] In some embodiments, one side of the connecting rope 12 passes through the top of the drying box 2 and extends outwards. In order to achieve the effect of discharging ammonium chloride particles that have accumulated to a certain extent in the net bag 13, the operator lowers the extended connecting rope 12. At this time, the net bag 13 will tilt downwards due to the relaxation of the connecting rope 12 on one side. At this time, the dried ammonium chloride particles in the net bag 13 can be unloaded to the bottom of the drying box 2.

[0031] In some embodiments, two fans 17 are symmetrically arranged inside the drying chamber 2. The fans 17 are welded to the inner wall of the drying chamber 2 by welding. The fans 17 are located below the mesh bag 13. During the granulation process, when the ammonium chloride particles fall into the mesh bag 13, the fans 17 are activated to generate directional airflow. The airflow blows from below the mesh bag 13 to the particles inside the mesh bag 13. Combined with the heat generated by the heating tube 41, it accelerates the evaporation of moisture on the surface of the particles and promotes the circulation of hot air inside the drying chamber 2, so that all parts of the particles are heated evenly.

[0032] Two symmetrically arranged fans 17 can form a stable and uniform airflow field, effectively improving drying efficiency, shortening drying time, and preventing particles from clumping or being incompletely dried due to uneven local heating. At the same time, the airflow can also prevent particles from accumulating in the mesh bag 13, ensuring that the particles are well dispersed in the mesh bag 13, further improving the drying effect.

[0033] In some embodiments, a dual-axis motor 15 is provided on one side of the top of the drying chamber 2. The dual-axis motor 15 is fixedly connected to the drying chamber 2 by bolts. Two winding wheels 14 are symmetrically provided on the dual-axis motor 15. Each winding wheel 14 winds up the extended connecting rope 12. The winding wheel 14 rotates clockwise to wind up and rotates counterclockwise to unwind the rope.

[0034] like Figure 4 As shown, during operation, the dual-axis motor 15 starts, driving the two winding wheels 14 to rotate synchronously. The net bag 13 is raised and lowered by winding or releasing the connecting rope 12. During granulation, the dual-axis motor 15 drives the winding wheels 14 to wind the connecting rope 12, pulling the net bag 13 upwards, bringing it closer to the cutting disc 11 to receive the cut granules. The dual-axis motor 15 driving the winding wheels 14 achieves electric lifting control of the net bag 13, allowing for flexible adjustment of its position without requiring manual holding of the connecting rope, ensuring accurate granule placement in the net bag 13. Simultaneously, the symmetrically arranged winding wheels 14 ensure the synchronicity of the connecting rope 12 winding, effectively preventing ammonium chloride granules from tilting and spilling before they are fully dried, thus improving the stability and reliability of the device operation.

[0035] In some embodiments, such as Figure 2 As shown, the drying chamber 2 is equipped with a tray 16, which is welded to the inner wall of the drying chamber 2. The tray 16 is located at the bottom of the mesh bag 13. During the ammonium chloride production granulation process, since there is a rotating stirring rod 4 below the mesh bag 13, in order to prevent the mesh bag 13 from being rolled into the rotating stirring rod 4 when it is tilted on one side, the tray is set below the mesh bag 13. The tray can support part of the mesh bag 13.

[0036] When the mesh bag 13 tilts for unloading, the support plate 16 supports the mesh bag 13, maintaining a safe distance between the mesh bag 13 and the mixing rod 4, preventing the mesh bag 13 from contacting and getting caught in the mixing rod 4. The support plate 16 ensures the safety of the mesh bag 13 during tilting unloading, preventing equipment failure or damage caused by contact between the mesh bag 13 and the mixing rod 4, ensuring stable operation of the device, extending the service life of the mesh bag 13 and the mixing rod 4, and reducing maintenance costs.

[0037] In some embodiments, the upper end of the connecting rope 12, which is connected to the top of the drying chamber 2, is coated with glue, causing the area to harden. During the loading process of the net bag 13, the material falling into it causes shaking. The hardening of the upper end of the connecting rope 12 due to the glue coating enhances its stability and reduces the shaking amplitude. By applying glue to the upper end of the connecting rope 12 to harden it, the stability of the connecting rope 12 is effectively improved, preventing particles from spilling or affecting the normal operation of the device due to shaking during loading. This improves the reliability and production efficiency of the device, and the operation is simple, easy to perform, and low in cost.

[0038] In some embodiments, the bottom end of the pressure plate 8 is conical, and the top end of the forming plate 9 is a conical groove structure. When the cylinder 7 drives the pressure plate 8 to press down on the ammonium chloride material in the loading box 5, the conical structure at the bottom end of the pressure plate 8 can fit tightly with the conical groove at the top end of the forming plate 9, so that the material can enter the forming hole of the forming plate 9 more smoothly under the extrusion action of the conical structure, reduce material residue, and improve extrusion efficiency and material utilization.

[0039] In some embodiments, the heating tubes 41 are symmetrically arranged vertically, and heating tubes 41 are installed at corresponding positions at the top and bottom of the drying chamber 2. When working, the upper and lower heating tubes 41 heat up at the same time, which can form a uniform heat field in the drying chamber 2, ensuring that the ammonium chloride particles are heated evenly in all parts during the drying process, avoiding uneven drying or inconsistent particle quality due to local temperature differences, and effectively improving the drying effect and the quality stability of the ammonium chloride particles.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
