Jinhe Machinery's pharmaceutical ultrasonic vibrating screens are favored by high value-added precision powder customers for their "sealed and dust-free, convenient cleaning, high screening efficiency, and accurate screening", among them are customers in the medical industry. Pharmaceutical ultrasonic vibrating screens play a vital role in industries such as traditional Chinese medicine powder, bulk medicine, and traditional Chinese medicine formula granules.
的延伸，是为了解决高精细粉末类物料在筛分过程中容易堵网而设计生产的。 The medical ultrasonic vibrating screen is an extension of the rotary vibrating screen . It is designed and manufactured to solve the problem that high-precision powder materials easily block the screen during the screening process. When the material is placed on the screen, it is subjected to the three-dimensional motion generated by the motor, and the screen is simultaneously subjected to the high-frequency and low-amplitude ultrasonic vibration wave of the ultrasonic screening system, so that the material is suspended at a low altitude on the screen, thereby solving the screening process Screening problems such as blocked nets, sticky nets, adsorption, troupes, static electricity, and light specific gravity.
The components of medical ultrasonic vibrating screens are generally divided into two parts: rotary vibrating screens and ultrasonic systems. The structure of the rotary vibrating screen has been introduced many times. Now we will focus on the detailed split introduction of the components of the ultrasonic system:
Ultrasonic screening system is the core functional system of medical ultrasonic vibrating screen, which mainly includes the following 6 components.
1. Ultrasonic controller: 30KHz high-frequency ultrasonic generator. The built-in microcomputer chip can automatically track the entire digital frequency according to the different states of the ultrasound, without manual adjustment, and the operation is simple and convenient.
2. High-frequency connection line: The cable is connected between the ultrasonic oscillator and the ultrasonic controller.
3. Connector: aviation connector.
4. Converter: high frequency ultrasonic transducer.
5.Ultrasonic grid: It consists of outer grid and resonance ring.
6. Screen mesh: applicable to 10 mesh ~ 635 mesh.
Generally speaking, the vibration frequency of medical ultrasonic vibrating screen is divided into 5 gears from C1-C5, corresponding to three vibration frequency modes: high frequency, intermediate frequency and pulse. The vibration frequency of medical ultrasonic vibrating sieve decreases in order from C1 to C5. In the production process, if the output is required, the ambassador can choose high frequency or intermediate frequency. If you need to adjust, just press the "mode selection button" on the ultrasonic controller. The following video is the method of adjusting the vibration frequency of the ultrasonic transducer system of medical ultrasonic vibrating screen. Friends who need it can watch it carefully.
1. The screen is easy to be damaged: At present, the ultrasonic vibration screen frame uses an adhesive structure. Under normal circumstances, the screen is not easily damaged. If the screen is often damaged during use, we need to check that our screen is in progress. If the material port is equipped with a buffer device, you can also install it by yourself if you don't have one. If the amount of feeding is too large, the screen will be in full load for a long time and the screen will be damaged. Please distribute the cloth evenly during the production process. Then there is the problem of screen quality. When you buy, please choose a regular screen manufacturer;
2. Seals are easy to be damaged: As the dust-proof and vibration-damping parts often have problems such as breakage, we can check whether there is burr on the contact part of the screen frame and the seal. If burr is found, it can be polished and smoothed. Another reason is that the tension of the screen frame is different around the installation. The uneven tension will cause the seal to be unevenly stressed, which will also cause the seal to be damaged. We can install the screen frame to uniformly stress the surrounding area. To avoid this problem;
3. Screen degumming: Because the grid structure used by the ultrasonic vibrating screen is an adhesive grid, we need to use gluing when installing the screen. The degumming phenomenon generally occurs during the company's own screen change. This is Due to insufficient drying time when sticking the net, under normal circumstances, the sticky net rack needs 8 hours to dry in winter and 4 hours to dry in summer. We can prevent the problem of degumming by grasping the time when sticking the net;
4. Insufficient tension of the screen: The tension of the screen is related to the screening accuracy. In the company's own installation of the screen, there is a problem of insufficient tension. In fact, the solution is very simple. We can use a specific screen. Tooling can solve this problem.
安装前，首先按照装箱单检查零部件是否完整齐全。 1. Before installing the medical vibrating screen , first check whether the parts are complete according to the packing list.
2. Install the equipment in accordance with the medical ultrasonic vibration screen installation diagram. The foundation should have sufficient rigidity and strength to support the full static and dynamic loads of the vibration screen. When installing, make sure that the screen is in a horizontal position.
3. Ensure that a minimum gap of 75mm should be maintained between the medical ultrasonic vibrating screen and non-moving parts such as the hopper and the chute.
4. The ultrasonic power source is AC110-220v, 50Hz. Check whether the AC220V power supply is normal.
5. The vibrating screen and the ultrasonic controller should be grounded reliably.
