Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine pretreatment, and in particular to a cleaning drum screen for the production of traditional Chinese medicine decoction pieces. Background Technology

[0002] The cleaning process in the production of prepared Chinese medicinal herbs mainly involves removing impurities, such as mud, sand, debris, or other substandard medicinal materials. Problems that may arise with rotary screens in this process include low screening efficiency, inconvenient cleaning, easy clogging or damage to the screen, and potentially poor adaptability to different medicinal materials.

[0003] While existing technologies can achieve a certain cleaning effect for traditional Chinese medicine, they have drawbacks: the existing rotary screens for cleaning traditional Chinese medicine lack convenient integrated feeding, cleaning, and discharging, resulting in a lack of convenient auxiliary feeding during the cleaning process, delaying the working time and causing waste. In view of this, we have proposed a rotary screen for cleaning traditional Chinese medicine decoction pieces production, which solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a cleaning drum screen for the production of Chinese herbal medicine slices.

[0005] The technical solution of this utility model is as follows: a cleaning drum screen for the production of Chinese herbal medicine slices, including a mounting frame, a rotating screen and a lifting plate. A bracket is fixed at the lower end of the mounting frame, and a rotating screen is rotatably mounted between the brackets. The rotating screen is a two-section design with a gap in the middle. A lifting plate is provided inside the rotating screen. Through holes are provided on the surfaces of the rotating screen and the lifting plate. The lifting plate is a center-of-gravity offset design. A winch is fixed at the upper end of the mounting frame.

[0006] When using this device, the Chinese herbs to be cleaned can be introduced into the rotating screen from one side of the rotating ring. The mounting frame is suspended by a hoisting device. Then, the lower third of the rotating screen is submerged in the external cleaning tank at the bottom. After the Chinese herbs enter the rotating screen, they are submerged in the lower part of the water body, thus achieving cleaning. The rotating screen can be driven by a motor. The vibration generated by the motor, as well as the through-hole design of the rotating screen and the lifting plate, allow mud and sand to enter the external water tank through the through-hole. During cleaning, the lifting plate can be pulled up and down repeatedly to achieve a shaking effect. After cleaning, the winch pulls the lifting plate upward. One end of the lifting plate touches the limit ring and stops rising, while the other end continues to rise to achieve tilting, which can facilitate the discharge of materials. This device has a convenient and continuous effect of cleaning Chinese herbs and filtering mud and sand, and has high practicality.

[0007] Preferably, a bearing is embedded inside the bracket, and a connecting frame is fixed between the rotating end of the bearing and the rotating screen. The bearing and connecting frame enhance the rotational stability of the rotating screen, reduce frictional loss, extend the service life of the equipment, and improve the smoothness of the cleaning process.

[0008] Preferably, a symmetrically designed retainer is fixed at the lower end of the mounting frame, and a fixed seat is fixed in the middle of the retainer. The rotating screen rotates relative to the fixed seat. The symmetrically designed retainer and fixed seat ensure the balance of the rotating screen during rotation, prevent deviation caused by vibration, and improve the stability and reliability of the equipment.

[0009] Preferably, the lower end of the winch is provided with a steel cable, which passes through the fixed seat and is fixedly connected to the upper end of the lifting plate. The steel cable connects the winch and the lifting plate, making the lifting operation of the lifting plate more precise and controllable, facilitating shaking cleaning and material dumping, and improving the convenience and efficiency of operation.

[0010] Preferably, the rotating screen has a through-type design on both sides, and a limiting ring is provided on one side of the inner wall of the rotating screen. The center of gravity of the lifting plate is biased towards the limiting ring. The through-type design of the rotating screen and the limiting ring structure, combined with the biased center of gravity of the lifting plate, allow the material to slide out naturally after washing, reducing manual intervention and improving the discharge efficiency.

[0011] Preferably, a mounting base is fixed on one side of the bracket, and a rotating motor is fixed on one side of the mounting base. The output shaft of the rotating motor is fixedly connected to the rotation center on one side of the bearing. The rotating motor enables the automated driving of the rotating screen, reduces manual operation, improves cleaning efficiency, and the vibration assistance of the motor enhances the separation effect of mud and sand.

[0012] Preferably, a rotating ring is rotatably installed on the outer wall of the rotating screen on the side away from the limiting ring. The rotating ring is fixedly connected to the connecting frame. The fixed connection between the rotating ring and the connecting frame further enhances the rotational stability of the rotating screen. When the material is pressed against the connecting frame on the rotating ring side to achieve feeding, the connecting frame will not rotate, but the rotating ring can make the rotating screen continue to rotate, achieving a clutch effect and facilitating feeding.

[0013] Preferably, the upper end of the mounting frame is fixed with buckles arranged in a square array. The square array of buckles facilitates the hoisting and fixing of the mounting frame, enabling the equipment to flexibly adapt to different working environments and improving the applicability and ease of installation of the equipment.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model achieves efficient and continuous cleaning of Chinese herbal medicines and filtration of sediment by optimizing the design of key components such as the rotary screen, lifting plate, and winch. The two-section structure and through-hole design of the rotary screen facilitate sediment discharge, while the offset center of gravity of the lifting plate and the winch control enable automatic tilting, improving cleaning and discharge efficiency.

[0016] Second, based on the first beneficial effect, the auxiliary structures such as bearings and rotating motors enhance the stability and automation of the equipment, reduce manual intervention, and the rotating ring can realize the clutch effect of the feeding end; the connecting frame and the rotating screen can achieve the effect of non-interference in feeding and washing. The overall design is reasonable, the operation is convenient, and it has high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
