Small rigid contact lens polishing liquid automatic cleaning device

Abstract

The invention relates to an automatic small-sized rigid gas permeable contact lens polishing liquid cleaning apparatus which mainly solves the problems that the existing rigid gas permeable contact lens polishing equipment can not automatically discharge waste liquid, waste liquid settled in an equipment tank is easy to overflow, and clean production environment cannot be maintained easily, and production efficiency is greatly reduced as waste liquid needs to be cleaned frequently during production process. The cleaning apparatus comprises a container, a containing cavity is arranged in the container, an exhaust pipe and a liquid absorption pipe which are communicated with the containing cavity are arranged on the container, an outlet end of the exhaust pipe is communicated with a vacuum opening of a vacuum generator by a connector, an air inlet of the vacuum generator is communicated with a compressed air pipe, and a liquid inlet of the liquid absorption pipe is arranged at the bottom of a waste liquid tank. The apparatus has the advantages of convenience in use, easiness for control and good safety, can timely and fast treat the polishing waste liquid so as to prevent influence of the waste liquid on the production environment, and can effectively improve production efficiency of a rigid gas permeable contact lens through automatic cleaning.

Description

technical field [0001] The invention relates to a waste liquid cleaning device, in particular to a small-sized hard corneal contact lens polishing liquid automatic cleaning device. Background technique [0002] Rigid contact lens (RGP lens) is currently one of the most effective methods and devices for correcting refractive errors recognized by the international optometry academic and industry circles. With the further development and promotion of RGP mirrors, the related production, polishing and testing equipment are also constantly being updated and improved. [0003] A kind of hard contact lens polishing equipment currently used is equipped with a waste liquid tank for storing the waste liquid left after polishing. Since the amount of waste liquid contained in the waste liquid tank is limited, the waste liquid cannot be discharged automatically and in time. Due to the limited capacity, the waste liquid deposited in the waste liquid tank will overflow, which is not condu...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies and defects in the background technology, the present invention provides a small-sized hard contact lens polishing liquid automatic cleaning device to solve the problem that the hard contact lens polishing equipment cannot automatically discharge waste liquid, and the waste liquid is easily overflowed when deposited in the waste liquid tank. It is not conducive to cleaning and environmental protection, avoiding the need to frequently clean up waste liquid during the polishing process, thereby effectively improving production efficiency
