Description

Technical Field

[0001] This utility model relates to an automatic screening device in water, belonging to the field of equipment manufacturing. Background Technology

[0002] In underwater industrial production and precision parts processing, the demand for underwater screening of small parts (such as ceramic discs, screws, and cylindrical workpieces) is increasing. Traditional equipment generally adopts a split design, consisting of an independent vibration source, control unit, and screening fixture, resulting in a large size, complex installation, and difficult handling. Existing screening fixtures are typically smaller than 300mm × 300mm, with a single filter screen specification, making it difficult to adapt to the diverse needs of products with different shapes. At the same time, in the long-term immersion environment, the vibration source and transmission components are susceptible to water vapor corrosion, leading to rust or circuit failure. The split structure also cannot effectively block water flow impact, exacerbating equipment wear and tear and affecting operational stability and screening accuracy.

[0003] While current screening machines on the market come in various styles, improvements are mostly limited to localized optimizations, such as simply increasing vibration frequency or improving local waterproofing, failing to systematically address the core issues. Split-type machines require frequent manual adjustments of vibration parameters, relying on human experience and lacking automated control modules, resulting in cumbersome and inefficient operation. The size limitations of the screening fixtures prevent them from meeting the screening needs of large batches or irregularly shaped products. Furthermore, the vibration transmission mechanism lacks precise guiding design, easily leading to swaying or energy loss, further reducing screening consistency and making it difficult to meet the stringent requirements of high-precision manufacturing scenarios.

[0035] 2. High-precision vibration transmission and stability

[0036] Linear bearing 5 guide design: The tie rod 6 passes through the linear bearing 5 and moves in the vertical direction, eliminating lateral sway and ensuring that the screening fixture 7 only performs linear reciprocating vibration, thereby improving screening accuracy and consistency.

[0037] The chain 10 is rigidly connected to the tie rod 6: the vibration source fixture 4 directly drives the screening fixture 7 through the tie rod 6 and the chain 10, which is efficient and lossless in power transmission and adapts to high-intensity continuous operation.

[0038] 3. Multiple layers of protection and optimized durability

[0039] The anti-splash cover covers the vibration source fixture 4: It adopts a sealed arc-shaped structure that extends to the side wall of the water tank 2, forming a double anti-splash barrier to prevent water vapor from corroding the core transmission components (such as chains and bearings).

Screening fixture 7 vibrates and separates: The screening fixture 7 vibrates up and down at high speed under the drive of the vibration source. Qualified products (such as small screws and ceramic pieces) fall into the water tank 2 through the bottom filter screen, while unqualified products (too large in size or not in shape) remain in the screening fixture 7.

[0078] Screening time control: After the preset time is reached, the time delay relay automatically cuts off the power supply to the vibration source, and screening stops.

[0079] (4) Post-screening treatment

[0080] Qualified product collection: Open the drain valve 21 on the side of water tank 2, drain the water, and then take out the qualified products.

[0081] Defective product cleaning: Loosen the quick clamp 12, disassemble the screening tool 7, and pour out the remaining defective products.

[0082] (5) Synergistic effect of key structures

[0085] Corrosion-resistant materials: Chain 10, pull rod 6, etc. are made of stainless steel or coated, suitable for long-term underwater operation.

[0086] Flexible adaptability:

[0087] Replaceable filter screen: The bottom filter screen of screening fixture 7 has a replaceable aperture and is compatible with round, square, and cylindrical products.

[0088] Quick-release clamp 12: Enables rapid assembly and disassembly of the screening fixture 7, supporting multi-variety production needs. Stability guaranteed.

[0089] Adjustable feet: Balance the stability of the housing 3 on different ground surfaces to ensure uniform vibration.

[0090] Emergency stop button: In case of emergency, immediately cut off power to protect the equipment and the safety of operators.

[0091] (6) Summary of application scenarios and advantages
