Crosslinking agent production device based on high-pressure filtration for oil field

Abstract

The invention relates to the technical field of oil field cross-linking agent production equipment, in particular to a cross-linking agent production device based on high-pressure filtration for an oil field through double-cavity stirring and graded filtration, which comprises an upper cavity, a lower cavity, a filter cartridge, a high-pressure scavenging port, a circulating stirring part, a mixing stirring part, a filter assembly and a purification net, the circulating stirring part is arranged in the upper cavity, the mixing stirring part and the purifying net are arranged in the lower cavity, and the filtering assembly is arranged in the filtering cylinder. Oil field crosslinking agent raw materials are uniformly stirred and mixed through the circulating stirring component and the mixing stirring component, cakes and impurities in the oil field crosslinking agent raw materials are separated through the filtering assembly, an oil field crosslinking agent is purified through the purifying net, and the lower cavity is inflated and sucked at regular time through the high-pressure scavenging port; the pressure circulation in the upper cavity and the lower cavity is increased and decreased, so that the filtering and purifying efficiency of the device on the oil field cross-linking agent is improved.
