Description

TECHNICAL FIELD

[0001] The utility model relates to a mesh washing device, in particular to a mesh washing device with telescopic cover. BACKGROUND

[0002] In the industrial production process, the forming mold and the filter screen as key components are easily blocked by various impurities on the surface after a period of continuous forming operation, so that it is necessary to use high-pressure water to clean and maintain them to ensure their normal use.

[0003] However, the current process of using high-pressure water to clean the forming mold and the filter screen exposes a series of serious problems. Due to the high water pressure generated by the high-pressure water impact, a large amount of high-pressure backflushing water and water mist splashes everywhere, and the working area is instantly filled with water, which not only causes unnecessary waste of water resources, but also makes the on-site environment messy. Moreover, the splashing water and water mist pose a great safety threat to the surrounding running equipment and various electrical components. The humid environment easily causes electrical short circuit, equipment failure and other risks, greatly shortens the service life of the equipment, and increases the maintenance cost and downtime of the enterprise.

[0004] To alleviate this dilemma, some enterprises try to design and install equipment guardrails or hard baffles. These protective facilities can block some splashing water to some extent, but the actual effect is far from ideal. On the one hand, during the non-working period of the mesh washing device, these fixed baffles will hinder the normal operation of other moving parts, limiting the overall coordination of the equipment and reducing production efficiency. On the other hand, the additional baffles undoubtedly increase the space occupation size of the equipment, which further aggravates the site congestion for some production sites with compact layout, which is not conducive to the subsequent upgrading and flexible layout of the equipment.

[0005] Therefore, it is urgent to develop an innovative protective device that can effectively block backflushing water and water mist during high-pressure water cleaning, ensure equipment and electrical safety, and cleverly avoid space occupation problems in non-working state without hindering the movement of other parts, achieving efficient use of space. The telescopic baffle device designed in this case is born at the right moment. Its unique double-layer hard-soft material baffle structure, combined with the flexible telescoping feature, can accurately deploy to achieve all-round water blocking during work, and shrink to a very small size during non-working, perfectly meeting the multiple needs of modern industrial production for efficient, safe and space-saving mesh washing devices.
