Feeding device at bottom of quartz crucible

Abstract

The invention discloses a feeding device at the bottom of a quartz crucible. The feeding device at the bottom of the quartz crucible comprises a third cylinder, a first cylinder and a second cylinder, wherein the first cylinder and the second cylinder are arranged above the third cylinder. The first cylinder and the second cylinder are parallelly arranged, and are perpendicular to the third cylinder. The front end of the third cylinder is connected with an output piston of the second cylinder. The rear end of the cylinder body of the third cylinder is connected with an output piston of the first cylinder; and a sand-blasting gun is arranged on an output piston of the third cylinder. The feeding device at the bottom of the quartz crucible is simple in structure, reasonable in design, good in using effects, capable of effectively solving the problem that prior manual coating is unstable in quality and large in labor intensity and brings difficulty to the next procedure, and accordingly improves the integral quality of the quartz crucible, and meanwhile is high in feeding efficiency and safe and reliable to use.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding device for the bottom of a quartz crucible, which is used for coating quartz sand on the bottom of a quartz crucible in a molding system of a quartz crucible blank. Background technique [0002] A typical method of manufacturing a quartz crucible is called a rotary mold method, in which quartz sand is attached to the inner wall of a rotary mold, that is, the bottom surface and side surfaces of the mold, and then melted by heating with electrodes to make a quartz crucible. [0003] The first step in the formation of the quartz crucible blank is the coating of quartz sand. First, the quartz sand is coated on the side wall of the inclined quartz crucible mold, and then the quartz crucible mold is placed vertically, and the quartz sand is coated on the quartz crucible. bottom of the mold. [0004] At present, manual sandblasting is often used to coat quartz sand on the quartz crucible. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a feeding device at the bottom of the quartz crucible, which has a simple structure, reasonable design and good use effect, and can effectively solve the problems of unstable manual coating quality and labor intensity in the prior art. It is large and brings difficulties to the next process, thereby improving the overall quality of the quartz crucible, and at the same time, the feeding efficiency is high, and the use is safe and reliable.
