Pressurized mixing device

Abstract

The invention belongs to the field of oil field fracturing equipment matching and in particular relates to a pressurized mixing device. The device comprises a mixing chamber, and a stirring shaft which stretches into the mixing chamber and is driven by a power source, wherein the upper part of the mixing chamber is communicated with a guide hopper; a liquid outlet is formed in the side wall of the mixing chamber; the bottom of the mixing chamber is communicated with a liquid inlet pipe; a residual liquid outlet is formed in a lower part of the liquid inlet pipe; the power source is erected on the mixing chamber by virtue of a supporting structure; the stirring shaft vertically stretches into the mixing chamber; a thrower body and a mixing impeller are fixed on the stirring shaft in a back-to-back manner in the mixing chamber; and the thrower body is arranged on the upper part, and the mixing impeller is arranged on the lower part. According to the device disclosed by the invention, three functions, such as a screw augur sand conveyer, a mixing tank and a discharge sand pump of the traditional sand mixing equipment, are combined into a whole, and the device is simple in structure, reasonable in design and uniform in fracturing fluid mixing.

Description

technical field [0001] The invention belongs to the supporting field of oilfield fracturing equipment, in particular to a booster mixing device. Background technique [0002] Traditional sand mixing equipment includes screw auger sand conveyor, mixing tank and sand discharge pump. The traditional equipment has complex structure, large volume, heavy weight, difficult processing, difficult assembly, high manufacturing cost, and poor reliability. [0003] In order to enhance the recovery rate of crude oil and better protect the environment of the oil production operation area, the fracturing process is constantly improving and improving, and more optimized sand mixing equipment is needed to help. Contents of the invention [0004] The purpose of the present invention is to overcome the above disadvantages and provide a pressurized mixing device, which integrates the three functions of the traditional sand mixing equipment, such as the screw auger sand conveyor, the mixing tan...
