Description

Technical Field

[0001] This utility model relates to the field of material screening equipment technology, and in particular to the structure of a multi-station linkage ultrasonic vibration screening system. Background Technology

[0002] Screening systems typically separate materials on a screen surface according to particle size through mechanical vibration or rotation. The feeding device is responsible for uniform feeding, and the grading channel diverts materials of different specifications. Multi-station linkage integrates screening, conveying, processing, and testing processes, and reverse-optimizes the structural parameters of the screening system. This upgrades the screening system from a single separation function to a key node for multi-station collaborative production, ultimately improving the efficiency and stability of the overall production line.

[0003] A search revealed Chinese Patent Publication No. CN205392941U, which discloses a material screening device, specifically a high-efficiency vibrating screening system. It includes one pre-screening machine and one secondary screening machine. Both the pre-screening machine and the secondary screening machine include a vibrating frame and a housing. The housing contains a screen body, which is divided into a first transition zone, a screening zone, and a second transition zone. Each screening zone has a plurality of screen holes evenly distributed. A fine material collection chamber is located on the lower side of the housing corresponding to the screening zone, and a vibrating motor is fixedly mounted outside the fine material collection chamber. The vibrating frame consists of a fixing component, an elastic component, and a support component. The fixing component is fixedly connected to the housing, and both ends of the elastic component are fixedly connected to the fixing component and the support component, respectively. The screen hole diameter of the screening zone in the pre-screening machine is 0.5-0.75 times that of the screening zone in the secondary screening machine. This invention has a simple structure, is practical and convenient, and has high screening efficiency.

[0004] The aforementioned patent specification mentions that "the vibrating frame is composed of a fixed component, an elastic component, and a supporting component. The fixed component is fixedly connected to the housing, and the two ends of the elastic component are fixedly connected to the fixed component and the supporting component, respectively. The screen aperture of the screening section of the pre-screening machine is 0.5-0.75 times that of the screening section of the secondary screening machine. This utility model has a simple structure, is practical and convenient, and has high screening efficiency." While the above description does mention high screening efficiency, some screening system structures require separate equipment for different screening stages. The transfer of materials between different devices relies on independent conveying devices, which is not only time-consuming but also leads to material loss or secondary pollution due to vibration and spillage during the transfer process. Therefore, a multi-station linkage ultrasonic vibration screening system structure is proposed to solve the above problems. Utility Model Content

With the opening and closing control of the electromagnetic control valve assembly, the combination of branch pipeline one with conveying air pump and connecting pipe efficiently returns the ultra-coarse impurities in the first screening chamber to the raw material silo for reprocessing, reducing material waste. The combination of branch pipeline two with the recovery box enables the targeted collection of unqualified impurities in subsequent screening stages, reducing the impact of impurities on the quality of finished products. The overall structure replaces manual or independent transfer with automated pipeline conveying, which not only shortens the material transfer time between processes, but also reduces material loss and secondary pollution risks caused by spillage during transfer, providing key support for continuous and large-scale screening of the system. 2. The ultrasonic vibration generated by the transducer is transmitted to the support ring through the transmission rod, which drives the screen fixed by the connecting buckle to achieve high-frequency vibration. It can perform efficient preliminary screening and subsequent fine classification of raw materials. Compared with the traditional single screening unit, the material can be finely processed step by step by adapting the screens in different screening chambers, which can meet the needs of multi-stage screening.

[0021] Reference Figure 1 , Figure 2 and Figure 4 The grading and screening mechanism 3 includes a support ring 31, which is externally fixedly connected to the interior of multiple screening chambers 2. The connecting line is used to transmit electrical signals from the control body 7 to realize remote control of the electromagnetic cylinder 583.

The connecting buckles 33 are used to fix the screen 32 and, through the slidable connection with the support ring 31, adapt to the vibration of the screen 32 to ensure that the screen 32 is installed stably. The screen 32 is externally slidably connected to the outside of the screening chamber 2. The screen 32 is the core component of screening, which realizes material grading through different apertures and completes material separation under high-frequency vibration. A transmission rod 34 is fixedly connected to the outside of the support ring 31. A transducer 35 is fixedly connected to the outside of the transmission rod 34. The transmission rod 34 transmits the vibration generated by the transducer 35 to the support ring 31, thereby driving the screen 32 to vibrate. The transducer 35 is connected to the control body 7 through the connecting line. Specifically, the support ring 31 is fixed inside the screening chamber 2, and the connecting buckle 33, which is slidably connected to the outside, fixes the screen 32 and adapts to vibration, ensuring that the screen 32 is installed stably. The support ring 31 is connected to the transducer 35 through the transmission rod 34. The transducer 35 receives the signal from the control body 7 through the connecting line and generates vibration, which is transmitted to the support ring 31 by the transmission rod 34, driving the screen 32 to vibrate at high frequency. The screen 32 achieves material classification and separation with different apertures during vibration, completing the precise classification and screening of materials, and ensuring screening efficiency and stability.

[0022] The implementation principle of this application embodiment is as follows: Material enters the first screening chamber 2 from the raw material silo 4 connected to the top screening chamber 2. The control body 7 operates synchronously through the connecting line, the synchronous transport mechanism 5, and the grading and screening mechanism 3. In the grading and screening mechanism 3, the transducer 35 generates ultrasonic vibration after receiving the control signal, which is transmitted to the support ring 31 via the transmission rod 34, causing the screen 32 fixed by the connecting buckle 33 to vibrate at high frequency, thus performing preliminary screening of the raw material. At this time, the electromagnetic cylinder 583 is driven by the control body 7 to drive the connecting column 582, causing the baffle 581 to slide in the main conveying pipe 51, thereby controlling the opening and closing of the pipe. If ultra-coarse impurities are generated after screening in the first screening chamber 2, the impurities pass through the... Branch pipe 52 outside screening chamber 2 enters the input end of conveying air pump 53. After being pressurized by conveying air pump 53, it flows back to raw material silo 4 through connecting pipe 54 for reprocessing. Qualified materials flow to the next screening chamber 2 through main conveying pipe 51 for finer grading and screening. When unqualified impurities are detected in subsequent screening chamber 2, the impurities enter the recovery box 56 through branch pipe 55 outside it for collection. Finally, qualified materials that have undergone multi-stage screening fall into the collection box 57 through the bottom of the bottom screening chamber 2 for collection. After the whole process is completed, the high-pressure air pump 6 can assist in cleaning the screen 32. The control body 7 monitors the status of each component in real time to ensure continuous and efficient screening.
