TECHNICAL FIELD
[0001] The utility model relates to the technical field of vibrating screen, specifically, relates to a mud vibrating screen. BACKGROUND
[0002] As a solid-liquid separation equipment occupying a key position in the widely industrial fields such as oil drilling, mining exploitation and building construction, the basic structure of mud vibrating screen covers core components such as screen box, vibrating motor, screen mesh and supporting device. The running mechanism of the equipment is based on the high-frequency vibration generated by the vibrating motor, and the vibration promotes the synchronous vibration of the screen box and the screen mesh. When the mud is transported to the upper side of the screen mesh, the solid particles and liquid part in the mud can be separated under the action of continuous vibration. Those solid particles with size meeting the aperture setting of the screen mesh will remain on the surface of the screen mesh and finally be discharged through the discharge port, and the separated liquid will pass through the screen mesh and flow out smoothly from the lower discharge port. Through this process, the mud vibrating screen can efficiently remove the large particle impurities in the mud, ensure that the performance indicators of the mud meet the strict requirements of the subsequent process flow, and thus significantly improve the efficiency and quality level of the whole production process. It is worth mentioning that when facing different working scenes and working conditions, the operator can flexibly adjust the vibration parameters of the vibrating motor and the specification size of the screen mesh, so that the equipment can accurately adapt to the solid-liquid separation tasks of various types of mud, showing good adaptability and flexibility.
[0003] In the existing technical system, the mud shaker is provided with spring components at the joint parts of the support device and the screen box. The main function of these springs is to absorb and buffer the vibration energy transmitted to the screen box by the vibration motor, thereby reducing the degree of vibration propagation to the support device and the equipment foundation, effectively preventing the occurrence of excessive vibration of the entire equipment, reducing the mutual impact force between the components due to vibration, providing practical protection for the screen mesh, vibration motor and other key components, and ultimately achieving the purpose of prolonging the service life of the entire equipment. However, since the vibration path of the screen box during operation presents an elliptical circular motion form, this leads to the problem of uneven force on the vertical springs. Specifically, during the continuous process of elliptical circular motion, the vertical acceleration and displacement of the screen box at different positions and times are in a dynamic process of continuous change, which directly causes the pressure and tension of the vertical springs to also continuously change, and the force conditions of the springs are significantly different. The negative effects of this uneven force are multifaceted. First, it significantly accelerates the fatigue and wear of the springs, greatly shortening the service life of the springs. Second, uneven force can interfere with the vibration stability of the screen box, thereby adversely affecting the screening effect of the mud. In addition, uneven force conditions may cause resonance of the springs, which will further exacerbate the damage risk of the springs, and in the long-term operation of the equipment, may cause the connection between the screen box and the support device to loosen, seriously threatening the reliability and safety of the entire equipment and potentially causing hidden dangers in the production process.

[0025] In actual use, the mud shaker of the present application drives the screen box 300 to perform elliptical trajectory vibration by the power assembly 200. At this time, the first positioning plate 700 connected with the screen box 300 moves with the screen box 300, generating vertical and lateral displacement changes. The second positioning plate 900 laterally slidably arranged on the support 100 provides buffering and guiding for the lateral displacement of the screen box 300. This design effectively avoids unnecessary pulling and twisting of the spring caused by lateral shaking of the screen box 300. In this way, it can ensure that the spring mainly undertakes the task of buffering vibration energy during the vibration of the screen box 300, rather than bearing additional stress caused by lateral shaking, prolonging the service life of the spring.
[0026] As a more preferred embodiment, the multi-stage screen structure 400 includes a first screening net 401 and a second screening net 402, both of which are arranged in the screen box 300 and are spaced apart in the screen box 300 along the inlet to outlet direction.
[0027] In the above embodiment, the arrangement of two-stage screening nets can separate the mud more finely. The first screening net 401 can first intercept larger particle impurities, and the second screening net 402 further processes smaller particles, thereby greatly improving the purification degree of the mud and ensuring that it meets more stringent subsequent process requirements. Secondly, the spaced apart arrangement allows the mud to have enough space and time to redistribute and uniformly flow to the second screening net 402 after being screened by the first screening net, avoiding the problem of mud blockage caused by too close screen nets, and improving the screening efficiency and continuous operation capability of the equipment.
[0028] As a more preferred embodiment, the first screening net 401 and the second screening net 402 are both provided with ultrasonic net frames 500, and any of the ultrasonic net frames 500 is provided with an ultrasonic transducer 600, which is used to connect an ultrasonic generator.
[0029] In the above embodiment, the introduction of ultrasonic waves can effectively prevent particles in the mud from being blocked and adhered on the screen net. By high-frequency vibration, the particles are always in a suspended and loose state, ensuring the continuous and efficient screening capability of the screen net, greatly reducing the frequency of manual cleaning of the screen net, reducing the time cost of equipment downtime maintenance, and improving the overall production efficiency. Secondly, the action range of the ultrasonic waves covers the two-stage screening nets, which can precisely act on particles of different particle sizes, further improving the screening accuracy of the mud, making the treated mud quality more stable and reliable, and meeting the harsh industrial production process requirements for mud quality.
[0030] As a preferred embodiment, the number of ultrasonic transducers 600 on any of the above ultrasonic mesh racks 500 is multiple, and arranged in sequence along the length direction of the above primary screening mesh 401 or the above secondary screening mesh 402.
[0031] In the above embodiment, multiple ultrasonic transducers 600 are arranged on the ultrasonic mesh rack 500 and arranged in sequence along the length direction of the screen mesh, which has significant advantages. This layout can ensure uniform distribution of ultrasonic waves on the entire screen surface, avoiding energy concentration or weak areas, so that mud particles on the screen can be subjected to stable and balanced ultrasonic waves at any position, thereby more effectively preventing particle blockage and accumulation, ensuring efficient and continuous operation of the screen, greatly improving the stability and reliability of screening. Moreover, the interval distribution of multiple transducers can flexibly adjust the emission combination of ultrasonic waves according to the actual working condition of the screen, and realize precise energy output control according to the mud concentration and particle distribution characteristics of different areas, further optimize the screening effect, improve the precision and efficiency of mud treatment, and also prolong the service life of the screen, reduce the maintenance cost and operating energy consumption of the equipment, providing a more advanced, efficient and economical solution for mud treatment operations in industrial production.
[0032] As a preferred embodiment, the number of the above buffer assemblies is multiple, and uniformly distributed on both sides of the width direction of the above screen box 300.
[0033] In the above embodiment, first, multiple buffer assemblies can more effectively absorb and disperse the impact force generated by the screen box 300 during vibration, avoiding structural damage caused by excessive local stress, and improving the overall stability and reliability of the equipment. Secondly, the design of uniform distribution on both sides of the width direction of the screen box 300 makes the buffering force received by the screen box 300 more balanced when vibrating, reducing the inclination or shaking of the screen box 300 caused by uneven stress, ensuring the horizontal state of the screen, which is conducive to the uniform distribution and efficient screening of mud on the screen.
[0034] As a preferred embodiment, two of the above buffer springs 800 are arranged in the transverse direction of the above screen box 300, and the above telescopic rod 801 is arranged between the two buffer springs 800.
[0035] In the above embodiment, two springs are arranged in the transverse direction of the screen box 300, and the telescopic rod 801 is arranged between the two springs, which has significant advantages. This layout helps to optimize the stress distribution of the screen box 300, and the interval arrangement of the springs can more evenly bear the vibration impact of the screen box 300 in the transverse direction, avoiding premature fatigue and damage of the springs due to concentrated stress, effectively prolonging the service life of the springs and reducing the maintenance cost of the equipment.
[0036] As a preferred implementation, the bottom side of the second positioning plate 900 is provided with a guide sliding block 901, and the support 100 is provided with a guide sliding groove 902 adapted to the transverse sliding of the guide sliding block 901.
[0037] In the above embodiment, the cooperation of the guide sliding block 901 and the guide sliding groove 902 provides the second positioning plate 900 with a precise transverse sliding path, so that the movement of the second positioning plate 900 during the vibration of the screen box 300 is more stable and controllable, effectively avoiding additional friction and collision due to shaking or deviation, reducing the wear of the components, thereby prolonging the service life of the equipment. Secondly, this guide structure can ensure that the displacement of the second positioning plate 900 in the transverse direction always remains within the ideal range, so that the vibration of the screen box 300 is more regular, thereby improving the screening effect of the mud on the screen mesh, and ensuring the accuracy and efficiency of solid-liquid separation.
