The present invention seeks to be achieved through the following technical solutions:
A kind of pre-mixed high pressure suspension grinding material water jet cutting and cleaning device, comprise that abrasive material refills device 15, abradant supply device 16, high pressure pump system, abrasive material isolating valve 12, feeding abrasive material valve 11 and nozzle 14, it is characterized in that: described high pressure pump system outlet is divided into two-way, main line through choke valve 8 directly to nozzle 14, bye-pass converges with main line behind choke valve 9, ejector 10, abradant supply device 16, abrasive material isolating valve 12 successively, and described ejector 10 also joins by pipeline and main line with feeding abrasive material valve 11; Abrasive material isolating valve 12 between described abradant supply device 16 and the main line plays the effect of feeding abrasive material and isolation.
Further for to reach the purpose that makes things convenient for control operation, described feeding abrasive material valve 11 and abrasive material isolating valve 12 can adopt motor-driven valve or pneumatic operated valve.
The present invention has compared following advantage with cutting of existing preceding mixing water jet abrasive and cleaning device:
1, have choke preventing function, the problem of abrasive material possibility blocking pipeline and shower nozzle has greatly reduced the wearing and tearing to isolating valve again when both effectively having avoided pressure variation or shutdown take place in the course of work, and blocking-proof result is good, long service life.
2, can by adjusting the proportioning of the rationed system of abrasive material choke valve 8 and 9, stablize, export equably the suspension high-pressure grinding material water jet of different content according to the material characteristic of different to be cleaned or cuttings, cutting and cleaning performance significantly improve.
3, high efficiency is raised the efficiency 3 to 5 times than same device commonly used at present.
4, energy consumption is low, production run continuously, safety and environmental protection.
5, simple in structure, easy to install and use, be easy to apply.
