Description

Technical Field

[0001] This utility model belongs to the field of separation machine technology, specifically a granular powder separation and recovery machine. Background Technology

[0002] Granules, due to their stable dosage and ease of storage, are increasingly widely used in pharmaceuticals, veterinary drugs, and food additives, leading to a continuously expanding market. As industry competition intensifies, companies are placing higher demands on production efficiency and cost control. During granule production, powder is inevitably generated during granulation and sizing processes. Effective recovery of this powder can not only reduce raw material waste but also lower waste disposal costs. Therefore, improving powder recovery rates has become a key direction for granule manufacturers to optimize processes and enhance market competitiveness, and the practicality of related separation and recovery technologies has attracted considerable attention.

[0003] In current granule production, the core technical problem of powder recovery is the low recovery rate caused by incomplete separation: existing recovery methods are difficult to achieve precise separation of granules and powder mixtures, especially powders with small particle sizes, which are easily lost with airflow or equipment gaps. This not only makes them unusable for production, resulting in raw material waste, but may also cause dust pollution due to dispersion, making it difficult to meet the dual needs of enterprises for efficient utilization of raw materials and clean production. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example:

[0024] A granular powder separation and recovery machine includes a frame 1, a cyclone separator 10, and a powder collection device 6. The cyclone separator 10 and the powder collection device 6 are respectively connected to the frame 1. The bottom of the cyclone separator 10 is provided with a discharge port 2, and the top is provided with a feed port 9 and a discharge port 8. The powder collection device 6 is connected to the discharge port 8. The powder collection device 6 includes a shell 15, a guide pipe 7, a mounting frame 14, and a filter cloth 16. The shell 15 is connected to the frame 1 and has a cavity inside. The top and bottom of the shell 15 are respectively provided with an exhaust port 11 and a powder drop port 17. A valve 5 is provided on the powder drop port 17. The guide pipe 7 is fixedly connected to the shell 15 and is also connected to the discharge port 8. A sealing ring 13 is fixedly connected to the side of the shell 15 near the top. The mounting frame 14 is connected to the sealing ring 13 and faces the through hole 12 in the middle of the sealing ring 13. The filter cloth 16 covers the outside of the mounting frame 14.

[0025] Specifically, during operation, the mixture of granules and granule powder enters the cyclone separator 10 through the top inlet 9 with the airflow. Due to the difference in mass and volume between the granules and powder in the mixture, the granules, being of greater mass, are rapidly thrown against the cylinder wall by the combined effects of centrifugal force and gravity within the cyclone separator 10, falling along the cylinder wall and finally exiting from the bottom outlet 2. During this process, the granules and powder are initially separated, and the separated granules can directly enter the subsequent process. The lighter powder continues to flow within the separator with the airflow, is not discharged through outlet 2, and ultimately enters the next stage through the top discharge outlet 8 with the airflow.

[0026] The airflow carrying powder enters the cavity of the housing 15 of the powder collection device 6 through the guide pipe 7. After entering the housing 15, the powder-laden airflow is constrained by the internal space and flows towards the mounting frame 14. The sealing ring 13 near the top of the housing 15 prevents the airflow from escaping through the gap between the mounting frame 14 and the inner wall of the housing 15, forcing the airflow through the filter cloth 16. The filter cloth 16 on the outside of the mounting frame 14 intercepts the powder. The airflow can pass through the pores of the filter cloth 16, while fine powder is blocked on the surface of the filter cloth 16. The design of the filter cloth 16 covering the mounting frame 14 maximizes the filtration area. The intercepted powder falls off the surface of the filter cloth 16 under the action of gravity and falls downward to the powder discharge port 17 at the bottom of the housing 15. A valve 5 is provided at the powder discharge port 17. When filtering powder, the valve 5 is closed, so that the airflow inside the housing 15 is forced to contact the filter cloth 16, thereby improving the powder separation effect and preventing the airflow from rushing out of the powder discharge port 17 and blowing away the collected powder.

[0027] This invention separates granules from powder in a mixture by utilizing the centrifugal force difference of the cyclone separator 10. The separated powder is filtered through the filter cloth 16 and recovered separately, which can be reused in granule production, reducing raw material waste and improving raw material utilization.

[0028] In a preferred embodiment, a material collection box 3 and a powder collection box 4 are provided on one side of the bottom of the frame 1; the material collection box 3 is connected to the discharge port 2, and the powder collection box 4 is connected to the powder discharge port 17. Further optimized, both the material collection box 3 and the powder collection box 4 are drawer-type structures. The material collection box 3, connected to the discharge port 2, is used to receive the granules separated by the cyclone separator 10, and the powder collection box 4, connected to the powder discharge port 17, is used to collect the fine powder filtered by the filter cloth 16. Both achieve separate collection of granules and powder, respectively. The drawer-type structure allows for quick and easy removal, facilitating material retrieval and cleaning, reducing downtime, improving operational efficiency, and preventing secondary pollution caused by material spillage during collection.

[0029] In a preferred embodiment, a top cover 21 is detachably connected to the top of the housing 15, and an exhaust port 11 is disposed on the top cover 21. The top cover 21 is detachably connected to the housing 15, which facilitates opening the housing 15 to inspect, clean, or replace the internal mounting bracket 14 and filter cloth 16; the exhaust port 11 is disposed on the top cover 21, which does not affect the disassembly and assembly of the top cover 21, while ensuring a stable discharge of clean airflow, thus balancing maintenance convenience and exhaust function stability.

[0030] In a preferred embodiment, the guide tube 7 is inclined. The inclined arrangement of the guide tube 7 can guide the powder-containing airflow into the housing 15 at a gentle angle, avoid vertical airflow impact, reduce airflow turbulence, and improve filtration efficiency.

[0031] In a preferred embodiment, an inner baffle 19 is provided inside the housing 15. The inner baffle 19 is a cylindrical structure and is located outside the mounting frame 14. The top of the inner baffle 19 is sealed and fixedly connected to the sealing ring 13. Further optimized, a plurality of vent holes 18 are provided on the side of the inner baffle 19 near the bottom. The inner baffle 19, as a cylindrical structure surrounding the outside of the mounting frame 14, forms an airflow guiding channel after being sealed and fixed with the sealing ring 13, preventing the powder-containing airflow from flowing disorderly within the housing 15. The bottom vent holes 18 allow the airflow to contact the filter cloth 16 after passing through the vent holes 18, ensuring that the airflow passes evenly through the filter cloth 16, improving the filtration effect, and reducing the shaking of the filter cloth 16 caused by airflow impact.

[0032] In a preferred embodiment, the inner wall of the inner baffle 19 is provided with a plurality of guide strips 20 in the vertical direction. The guide strips 20 extend in a spiral shape and have a height of 3-8 mm. Specifically, during use, the airflow inside the housing 15 passes through the filter cloth 16 and is discharged from the exhaust port 11. The purpose of providing a plurality of guide strips 20 in the vertical direction on the inner wall of the inner baffle 19 is to guide the upward airflow and reduce the interference of turbulence on the filtration effect of the filter cloth 16.

[0033] In a preferred embodiment, the filter cloth 16 is an antistatic filter cloth, and the filter cloth 16 is detachably connected to the mounting bracket 14 via Velcro or snap fasteners. The antistatic filter cloth can prevent powder from being attracted to the surface of the filter cloth 16 due to static electricity generated by friction, reducing powder residue and preventing safety hazards caused by static electricity; the detachable connection method of Velcro or snap fasteners facilitates quick replacement of the filter cloth 16 and improves maintenance efficiency.
