Description

Technical Field

[0001] The utility model relates to the technical field of oil-based rock cuttings proportioning, in particular to an oil-based rock cuttings proportioning device for cement production. Background Art

[0002] China is rich in shale gas resources, with recoverable reserves ranking first in the world. In 2020 alone, production reached 20.04 billion cubic meters. Due to the high clay content in shale formations, hydration and expansion easily occur when in contact with water. Before entering the shale gas target layer, oil-based drilling fluids with high temperature resistance, good lubricity, good stability of the well wall and little damage to the oil and gas layer must be used, which produces a large amount of oil-based rock cuttings. Existing high-temperature industrial furnaces (cement kilns, sintered brick factories, coal-fired boilers in power plants, iron-making blast furnaces, etc.) dispose of oil-based rock cuttings in coordination with other raw materials or fuels.

[0003] Therefore, during cement production, cement and oil-based rock chips can be mixed for coordinated production. However, the oil-based rock chips need to be pretreated during production to avoid moisture during processing and storage that affects later production. Oil-based rock chips will produce odor during production, so they also need to be treated to avoid affecting the processing environment. Utility Model Content

Through the feed pipe connected to the tank body, personnel can inject cement materials and oil-based rock cuttings that need to be processed and produced into the tank body.

[0015] Preferably, a support frame is welded to the bottom end surface of the load-bearing panel, and a total of four support frames are provided, and the four support frames are distributed in a rectangular array relative to the load-bearing panel. The load-bearing panel can be installed and fixed by installing the support frame on the foundation.

[0016] Preferably, mounting blocks 2 are welded at both ends of the outer surface of the box, and the end of the mounting block 2 away from the box is welded to the mounting frame.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. The utility model provides a tank body and a box body. When personnel produce cement, the tank body is connected through a feed pipe, so that the personnel can inject cement materials and oil-based rock chips that need to be processed and produced into the tank body. After injection, the electric heating tube can be turned on to heat the materials in the tank body.
