Description

TECHNICAL FIELD

[0001] The present application relates to the field of industrial production, in particular to a vibrating screen with adjusting function. BACKGROUND

[0002] In the field of industrial production and engineering construction, vibrating screen as an important separation equipment is widely used in the screening, grading and dewatering process of various materials. Especially in the field of thermal power projects, construction, mining and other fields, vibrating screen plays an irreplaceable role in treating impurities in water and realizing solid-liquid separation.

[0003] Taking thermal power projects as an example, in many large coal-fired power projects, a large amount of water source needs to be treated, which may come from natural water bodies, depression water or underground water around the project. The existing vibrating screen equipment has many problems when treating such depression water source: Firstly, the filtering effect is not ideal. After the water source is preliminarily treated by the sedimentation tank, it still contains a large amount of floating matter and impurities. The existing vibrating screen has simple filtering structure and low filtering precision, which cannot effectively intercept these impurities, leading to frequent failures of subsequent equipment and affecting the normal operation of the whole water treatment system. The root cause of this problem lies in the unreasonable design of the filtering assembly of the existing vibrating screen, which lacks effective double filtering mechanism and cannot filter according to the characteristics of impurities in the water source.

[0004] Secondly, the equipment adaptability is poor. Different project sites and construction stages require different sizes of drainage blind trenches, while the traditional vibrating screen structure is fixed and cannot adjust its size to adapt to different specifications of drainage blind trenches, resulting in low matching degree of the equipment and the trench, affecting the drainage efficiency and filtering effect. The reason for this problem is that the existing vibrating screen lacks flexible and reliable adjusting structure, which cannot adjust the distance of key components, greatly limiting the universality of the equipment.

[0005] Thirdly, the equipment is easy to be blocked and difficult to be cleaned. In the process of deep foundation pit drainage, silt and impurities in the water are easy to accumulate in the vibrating screen, causing equipment blockage. The cleaning method of the existing vibrating screen mainly relies on manual cleaning, which not only has high labor intensity, but also seriously affects the operation efficiency of the equipment if not cleaned in time. The reason is that the existing equipment lacks effective automatic cleaning mechanism and cannot clean the impurities attached to the screen surface in time during operation, leading to frequent blockage problems.

[0006] In summary, the existing vibrating screen has obvious shortcomings in filtering effect, adaptability, automatic cleaning ability and power adaptability, which cannot meet the needs of depression water treatment in the field of thermal power projects and other fields. Therefore, a new type of vibrating screen with adjusting function, good filtering effect, not easy to block and strong power adaptability is urgently needed. SUMMARY
