Pre-mixed abrasive jet continuous feeding system

Abstract

The invention discloses a front mixing grinding material jet-flow continuous feeding system. The front mixing grinding material jet-flow continuous feeding system comprises a main water tank, a high pressure pump, a low pressure pump, a continuous feeding system, and a mixing chamber, wherein one end of the main water tank is communicated with the high pressure pump; an outlet of the high pressure pump is connected with an inlet of the mixing chamber; an inlet of the low pressure pump is connected with the inlet of the mixing chamber through the continuous feeding system; the continuous feeding system comprises a feeding system and a pressurization system; the feeding system is communicated with the pressurization system; an outlet of the mixing chamber is communicated with a nozzle. The front mixing grinding material jet-flow continuous feeding system realizes the truly significant continuous feeding, overcomes the phenomena that the continuous working time is short and the grinding material is short of supply in the working process, can greatly improve the working efficiency and the work quality of the system, and facilitates industrialized popularization of the front mixing grinding material jet flow technology; secondly, the difference between the piston areas on the two sides of a piston rod can play the pressurization effect.

Description

technical field [0001] The invention relates to a front mixing abrasive jet feeding device for a jet cutting machine tool, in particular to a front mixing abrasive jet continuous feeding system. Background technique [0002] Abrasive jet technology first appeared in the United States in the 1960s. International large-scale research and application of abrasive jets began in the late 1970s and developed rapidly in the 1980s. High-pressure water jet is a new technology that has developed rapidly in recent decades. In recent years, with the rapid development of large-scale, intelligent and specialized high-pressure water jet equipment, this technology has penetrated into many application fields: from the cleaning of general mechanical parts and buildings to the cleaning of pipes, tube bundles and containers. Industrial cleaning, from airport runway glue removal to ship rust removal; from metal and non-metal plate cutting to curved surface profiling cutting; from hydraulic coal ...

Problems solved by technology

[0003] Since the pre-mixed abrasive jet system needs to be in a closed and high-pressure working condition, the laboratory generally uses short-time or intermittent work in the test, and has not been able to achieve uninterrupted long-term work, which seriously hinders this technology. Industrialization application of

The Chinese patent discloses a front-mixing abrasive jet double-filling continuous feeding device. Although it can achieve "uninterrupted" work to a certain extent, in fact it uses another tank after the material in one tank is used up. The material in the tank, and the material tank needs to go through a complex and cumbersome process such as pressure relief-filling-boosting-feeding, not only requires a higher pressure tank, but also the filling time of each tank is long, and the work shorter time

Especially during the alternate process of the two tanks, there will be a blank period of feeding in the system, so the current front-mixing abrasive jet double-fill continuous feeding device cannot fully realize continuous feeding
