[0002] In the field of pharmaceutical crushing technology, it is very important to ensure the uniformity and consistency of the material, because it not only affects the color difference of the drug, but more importantly, it affects the effect and safety of the drug. The uneven mixing of coarse and fine particles may lead to inaccurate dosage, thereby affecting the drug efficacy and patient safety.
[0003] Traditional powder collection methods usually include the application of single devices such as cyclone separators and bag-type dust collectors.

[0004] Disadvantages of existing technology:

For the crushing of drugs, the different particle sizes of materials and the color difference of materials have a great influence on the later preparation.
[0006] 2) The traditional cyclone collection system can only effectively collect particulate matter within a specific particle size range. It has weak capturing ability for fine particles, which enter the bag collector with induced air.
[0007] 3) The traditional system may not have a dedicated recycling conveying pipe, resulting in two collection systems with different powder particle sizes and color differences, which have a great influence on the preparation of drugs.
[0008] Especially when dealing with materials with strong viscosity, materials can easily accumulate inside the pipe and equipment, which may cause system blockage after long-term operation, affecting normal production. Utility model content

DETAILED DESCRIPTION
[0021] To make the objectives, technical solutions and advantages of the patent embodiments clearer, the technical solutions in the patent embodiments will be described clearly and completely below with reference to the drawings in the patent embodiments.
[0022] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the patent nor its application or uses.
[0023] It is to be noted that the terms used herein are merely for the purpose of describing the specific embodiments and are not intended to limit the exemplary embodiments according to the patent.
[0024] Unless specifically stated otherwise, the relative arrangements of components and steps, numerical expressions, and values set forth in the examples herein are not intended to limit the scope of the patent. At the same time, it should be clear that the sizes of the various parts shown in the drawings are not drawn in accordance with the actual proportion relationship. The techniques, methods and devices known to those skilled in the art can not be discussed in detail, and in all examples shown and discussed herein, any specific value should be interpreted as merely exemplary, not as a limitation. Therefore, other example values of the exemplary embodiments can have different values.
[0025] As Figure 1 shown, the utility model discloses a combined powder collection system, including cyclone collector 1, dust collector 2, connecting fan 3, transition bin 4, crushing material inlet 5, collection conveying pipe 6 and recycling conveying pipe 7, cyclone collector 1 is provided with crushing material inlet 5, and the top of cyclone collector 1 is provided with collection conveying pipe 6, and cyclone collector 1 and dust collector 2 are communicated by collection conveying pipe 6, and the air outlet of connecting fan 3 is connected with the air inlet of dust collector 2, and transition bin 4 is connected at the bottom of dust collector 2, and one end of recycling conveying pipe 7 is communicated with transition bin 4, and the other end of recycling conveying pipe 7 is connected at crushing material inlet 5.
[0026] The cyclone collector 1 is mainly used for preliminary removal of larger particles in the crushed material, improving the efficiency of the subsequent dust removal process. The solid particles in the gas are separated by centrifugal force. The cyclone collector 1 rotates the crushed material into a cylindrical container along the tangent direction, and the heavier particles are thrown to the wall due to the centrifugal force and move downward along the wall, and finally discharged from the bottom; while the purified material enters the dust collector 2 from the top along the collection conveying pipe 6. The dust collector 2 collects fine particles by electrostatic or filtration, and the induced fan 3 helps maintain the airflow circulation of the entire system and ensures sufficient negative pressure to promote the effective collection of the crushed material. The transition bin 4 is used as a temporary storage place for the collected powder material. It helps to smoothly control the material flow to the downstream process or recycling loop. The transition bin 4 not only plays a buffering storage role, but also realizes precise control of the material flow by setting multiple pneumatic butterfly valves. The recycling conveying pipe 7 allows the collected powder material to be reintroduced into the system for further processing, ensuring uniform mixing of coarse and fine particles, while achieving the recycling of the material. In this way, material waste can be reduced while maintaining the continuity of the production process.
[0027] A first pneumatic butterfly valve 8 is arranged at the left outlet of the transition bin 4, and a second pneumatic butterfly valve 9 is arranged at the connection between the right outlet of the transition bin 4 and the recycling conveying pipe 7.
[0028] A third pneumatic butterfly valve 10 is arranged at the inlet of the transition bin 4.
[0029] The transition bin 4 serves as a temporary storage space, which can balance the fluctuation of material flow in the production process. When the output of upstream equipment (such as cyclone collector and dust collector) exceeds the demand of downstream process, the transition bin can temporarily store the excess material to avoid overflow or waste. Conversely, if the downstream process needs more material while the output of upstream equipment is insufficient, the transition bin can provide additional material to ensure continuous production.
[0030] By setting multiple pneumatic butterfly valves (such as the first pneumatic butterfly valve 8, the second pneumatic butterfly valve 9 and the third pneumatic butterfly valve 10), the transition bin can precisely control the flow direction of the material. This helps to guide the material to the correct processing path, whether it is sent for further processing or recycled. The pneumatic butterfly valve can be quickly opened or closed according to actual needs, improving the flexibility and response speed of the system.
[0031] The transition bin can effectively reduce the possibility of material blockage during transportation. Especially for materials with strong viscosity, the transition bin can provide a relatively spacious space for the material to disperse, thereby reducing the risk of blockage.
[0032] By being equipped with a vibration motor, the transition hopper can start vibrating when necessary to prevent the powder from caking due to long-term standing. This not only ensures the flowability of the material, but also reduces the risk of equipment failure caused by caking. Even if there is a temporary problem in a certain link, the transition hopper can maintain the continuity of production, avoiding the stoppage of the production line.
[0033] The inside of the cyclone collector 1 is provided with a spiral guide plate. The spiral guide plate is used to guide the powder to descend along a spiral path to improve the powder collection efficiency.
[0034] The vibration motor can be started periodically to vibrate the wall surface of the transition hopper 4, preventing the powder from caking due to long-term standing and ensuring smooth flow of the powder.
[0035] The above-described specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above-described specific embodiments are merely examples of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
