Feeding device capable of preparing oilfield auxiliaries at constant speed in timed manner

The invention relates to the technical field of feeding devices and discloses a feeding device capable of preparing oilfield auxiliaries at a constant speed in a timed manner. The feeding device comprises a support, a conveying device, a preparing device, a feeding device body and a high-pressure water pipe. The conveying device is fixedly installed on the support. The preparing device is fixedly installed at the feeding end of the conveying device. The feeding end is arranged on the upper portion of the feeding device body. A discharging end is arranged at the bottom of the feeding device body. The feeding device is reasonable and compact in structure and convenient to use. Due to the cooperative use of the conveying device, the preparing device, the feeding device body, the high-pressure water pipe, a mixed liquid pipeline and a high-pressure water pipeline spraying nozzle, one-time feeding is achieved; the feeding speed and the discharging speed of solid powder materials can be automatically controlled in the timed manner; the situation that because the adding amount of the solid powder materials is not stable, particulate matter, precipitate and lumps exist, and the pipeline and the high-pressure water pipeline spraying nozzle are blocked is avoided; the feeding device has the beneficial effects of being safe and reliable; operation is facilitated; production cost and labor intensity of operators are reduced; and work efficiency is improved.
