External-mixing polishing gun for glass ware

Abstract

The invention discloses an external-mixing polishing gun for a glass ware. The external-mixing polishing gun for the glass ware comprises a gun body with an inside hollow cavity. A group of air outlet holes are formed in one end face of the gun body. The other end face of the gun body is communicated with a main gas pipe. The side face of the gun body is communicated with a combustion-supporting gas pipe. The main gas pipe and the combustion-supporting gas pipe are both matched and communicated with the inside hollow cavity of the gun body. The external-mixing polishing gun for the glass ware is characterized in that the inside hollow cavity of the gun body is separated into a first cavity and a second cavity through a separator, and the two cavities are independent relatively; a group of gas-guide pipes are arranged at the end faces of the air outlet holes; the gas-guide pipes penetrate through the separator and communicate the first cavity and the outside world, the air outlet holes communicate the second cavity and the outside world. The external-mixing polishing gun for the glass ware has the advantages that the safety is good, tempering is avoided, and the service life is long; the defect like bubbling does not occur to a product; the combustion value is high, the firepower is concentrate, the flame is stable, gas can be burned sufficiently, and the fuel gas cost is saved effectively.

Description

technical field [0001] The invention relates to a glassware product surface polishing device, in particular to a glassware external mixing polishing gun. Background technique [0002] At present, the production of the glass industry uses two kinds of gases mixed in and then burned and polished, one combustion gas such as liquefied petroleum gas or natural gas, and the other combustion-supporting gas such as oxygen. The two gases are mixed in the polishing gun body through the pipeline, and then come out through the gun head to become a mixed gas for combustion to achieve the polishing effect. There are the following deficiencies: 1. When the mixed gas burns because the pressure is unstable or the ignition is turned off when the gas is turned on If the order is wrong, tempering will occur, which can cause an explosion (we usually say blasting) and it is easy to burst and the polishing gun is not safe. 2. The combustion value is not high, the firepower is not concentrated, th...
