Technical Field
[0001] The utility model relates to the technical field of preparation and production of pharmaceutical preparations, in particular to a rapid and uniform screening device for pharmaceutical preparations. Background Technique
[0002] There are various types of pharmaceutical preparations with wide uses. In the production and processing of pharmaceutical preparations made from Chinese herbal medicines, corresponding screening devices are often required to screen and select the raw materials of the medicines.
[0003] Since the screening device for pharmaceutical preparations can often only achieve single air separation screening or single vibration screening in actual operation, the former has the problems that the screening effect is not fine and uniform enough, and the quality of the obtained raw materials of the medicines is not good enough. The latter has the problems of heavy screening burden, too many impurities easily causing clogging of the filter holes, and affecting the screening efficiency. Moreover, the functionality of the device is low, and it does not have a drying treatment function, which affects the processing effect and can no longer meet the needs of people. For this reason, we propose a new type of rapid and uniform screening device for pharmaceutical preparations to solve the above-mentioned defects and provide a better processing effect. Content of the Utility Model
[0004] The purpose of the utility model is to provide a rapid and uniform screening device for pharmaceutical preparations to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A rapid and uniform screening device for pharmaceutical preparations, including a carrier frame, and also including
[0006] A primary air separation box, the primary air separation box is welded to the top end inside the carrier frame. A heavy waste residue outlet, a qualified material outlet, and a light waste residue outlet are sequentially arranged at the bottom of the primary air separation box. A feeding port is arranged at the top end of the primary air separation box. One end of the feeding port is provided with a hot air housing and a blower. An electric heating wire and a temperature sensor are installed inside the hot air housing;
[0007] A secondary vibration screening box, the secondary vibration screening box is connected to the bottom of the qualified material outlet. A vibration substrate is suspended inside the secondary vibration screening box. Composite springs and limiting telescopic rods connected to the secondary vibration screening box are uniformly arranged at the bottom of the vibration substrate;
[0008] A vibration motor is installed on the outer side wall of the vibration substrate, and a porous screening drawer is magnetically fixed on the top of the vibration substrate.
[0009] Furthermore, the output end of the blower is installed inside the bottom end of the hot air housing, and the input end of the blower is threadedly connected with a filter mesh cylinder, so as to filter and prevent blockage of the inlet of the blower.
[0010] Furthermore, a screw feeder matching the feeding port is installed on one side of the carrier frame, and a feeding trough is arranged at the bottom on one side of the screw feeder, facilitating the realization of the automatic and uniform feeding function by means of the screw feeder.
[0011] Furthermore, electromagnetic locks are uniformly fixed on the vibration substrate, and adsorption blocks matching the electromagnetic locks are fixed on the outer side wall of the porous screening drawer. The adsorption blocks are made of permanent magnets, facilitating the realization of the quick disassembly, installation and maintenance of the porous screening drawer by means of the magnetic attraction structure composed of the electromagnetic locks and the adsorption blocks.
[0012] Furthermore, the limiting telescopic rod is arranged inside the composite spring, and the top and bottom of the limiting telescopic rod are respectively welded to the top and bottom of the composite spring, enabling the limiting telescopic rod to limit and guide the composite spring and ensuring its telescopic movement in the vertical up and down direction.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0017] The rapid and uniform screening equipment for the preparation medicine optimizes its own performance by installing a blower, etc. On the one hand, when the medicinal material raw materials enter through the feeding port, the blower starts to introduce air into the inside of the feeding port. This enables the medicinal material raw materials to achieve primary air separation screening under the dual action of their own gravity and wind force. The heavier gravel, defective materials, etc. will enter the heavy waste residue outlet closest to the feeding port and be discharged, while the lighter broken leaves, waste materials, etc. will enter the light waste residue outlet farthest from the feeding port and be discharged. The qualified materials will enter the inside of the secondary vibration screening box through the qualified material outlet. At this time, the vibration motor on the outer wall of the vibration substrate starts, and with the elastic buffering effect of the composite spring with a built-in telescopic rod for limiting, it can drive the porous screening drawer magnetically fixed on the top of the vibration substrate to perform secondary vibration screening treatment. Thus, the device improves the rapid and uniform screening treatment of the preparation medicine raw materials by setting up a two-stage screening structure composed of air separation and vibration screening, solving the problems of low screening quality caused by a single screening structure, inconvenient one-time screening due to excessive material impurities, and low efficiency. On the other hand, by using the heating wire and temperature sensor installed inside the hot air housing, the temperature of the air introduced into the device can be regulated. While the hot air completes the air separation function, it realizes the drying and protection of the medicinal material raw materials and enhances the functionality.

[0030] A vibration motor 13 is installed on the outer side wall of the vibration substrate 11, and a porous screening drawer 14 is magnetically fixed on the top of the vibration substrate 11;
[0031] The output end of the blower 1 is installed inside the bottom end of the hot air housing 10, and a filter screen cylinder is threadedly connected to the input end of the blower 1; so that the inlet of the blower 1 can be filtered and protected against blockage;

The user can pour the medicinal material raw material products into the feeding trough at the input end of the screw feeder 9 in advance. Subsequently, the screw feeder 9 can automatically and evenly convey the medicinal materials upward into the inside of the feeding port 8. While the medicinal material raw materials enter through the feeding port 8, the blower 1 starts to introduce air into the inside of the feeding port 8. This enables the primary air separation and screening of the medicinal material raw materials under the dual action of their own gravity and wind force. Heavier gravel, defective materials, etc. will enter the heavy waste residue outlet 20 closest to the feeding port 8 and be discharged, while lighter broken leaves, waste materials, etc. will enter the light waste residue outlet 5 farthest from the feeding port 8, and the qualified materials will enter the inside of the secondary vibrating screening box 3 through the qualified material outlet 6.
