A liquid conveying device and a device for adding grinding liquid to a grinding disc

Abstract

The invention provides a liquid delivery device. The device comprises a vacuum generator with three ports, a liquid extraction pipe connected to the first port of the vacuum generator, a compressed air input pipe connected to the second port of the vacuum generator, a connecting pipe connected to the third port of the vacuum generator, an air-liquid separation container connected to the other end of the connecting pipe, a liquid outlet pipe connected to the bottom end or lower portion of the air-liquid separation container and an air exhaust pipe connected to the top end or upper portion of the air-liquid separation container, wherein the other end of the liquid extraction pipe is connected with a first liquid container and the other end of the compressed air input pipe is used for connecting compressed air. The invention further correspondingly provides a device for adding grinding liquid into a grinding disc. By replacing a liquid adding pipe and a mixing and pumping motor in the prior art with the liquid delivery device provided by the invention, the phenomena that the pipe is stuck by the grinding liquid and the motor is burnt out can be thoroughly avoided.

Description

technical field [0001] The invention belongs to a liquid conveying device, in particular to a conveying device for liquids with high solid content or high viscosity instead of existing pump equipment. Background technique [0002] During the preparation of glass products or sapphire products, the grinding process is inevitably involved. When grinding the product, the grinder must add a well-adjusted grinding liquid. The solid content of the grinding liquid is high, so its concentration is high (low fluidity), and it needs to be stirred continuously during use to ensure that the grinding powder does not settle. And the grinding solution concentration does not change. Such as figure 1 As shown, during the grinding process of the product, the milling liquid stirred in the grinding liquid barrel 02 is pumped to the grinding disc 01 through the liquid filling pipe 03 through the electric water pump (that is, the stirring pumping motor 05), and the grinding disc is soaked in the...

AI Technical Summary

Problems solved by technology

In this scheme, first, due to the high concentration of the grinding liquid, the liquid filling pipe 03 is often blocked; second, the stirring water pump in the grinding liquid bucket is also often blocked; third, the grinding liquid is a liquid, once it enters the motor of the electric water pump Internal accidents such as electric shock and motor burnout are prone to occur; fourth, this method is basically to artificially control the valve on the pipeline to add abrasive fluid, and it has not yet been automated.

Generally speaking, in the prior art, the pipes of the grinding fluid delivery device are easy to block, the water pump is easy to block, and the stirring motor is easy to burn out. A large number of maintenance personnel are required to repair and replace them, which is time-consuming and laborious, and the production cost is increased.
