AI Technical Summary

Problems solved by technology

[0003] When transporting solid particles to a closed system, it is usually necessary to carry out a pulping process and use a slurry pump to inject it into the equipment. There are complicated procedures, a large number of equipment, large power consumption, serious wear of the pump, short operating cycle, large amount of maintenance and operating costs. High disadvantage

At present, the service life of the most used centrifugal slurry pumps, such as the impeller, sheath shaft, and volute, is generally 500 to 1,000 hours, which not only causes a great waste of manpower and material resources, but also affects the normal production of the device.

[0004] Chinese patent CN86209508U introduces a vertical hydraulic conveying device, which is composed of multiple (sets) of equipment and valve groups, and is used for conveying ash, slag and coal powder in thermal power plants. It has the disadvantages of complex devices and the need for slurry pump transportation.

Chinese patent CN87206593U introduces a hydraulic conveying device, which is composed of ash pump, high-pressure water pump, oil motor, oil pump, valve group and other equipment. Disadvantages such as slurry pump transportation and easy blockage
