AI Technical Summary

Problems solved by technology

The heat-resistant and acid-resistant bricks are prone to fracture and peeling under the action of alternating temperature and internal stress, and the rapid change performance is poor, thereby affecting the service life of the kettle and even causing production stoppage; the quality requirements for leaching products at home and abroad are greatly improved
In addition, the existing heat-resistant and acid-resistant bricks have a single structure, which is inconvenient to install and disassemble

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As mentioned above, the acid-resistant, high-temperature-resistant, high-pressure-resistant cylinder opening ceramic brick of the present invention includes a cuboid brick body 1, which is divided into two from the middle, and a circular shape is opened in the thickness direction of the cuboid brick body 1. Hole 2; said cuboid brick body 1 is divided into two connecting blocks 3 with the same length from the middle of the length direction; said circular hole 2 runs through said cuboid brick body 1; said circular hole 2 is opened in said cuboid One side of the brick body 1 deviates from the center of the rectangular parallelepiped brick body 1; the diameter of the circular hole 2 is 100-250 mm; the ratio of the diameter of the circular hole 2 to the width of the rectangular parallelepiped brick body 1 is 1 / 1.2- 1.5. The inventio...

Abstract

The invention relates to an acid-resistant, high temperature-resistant and high pressure-resistant earthenware brick for a cylindrical shell entrance. The acid-resistant, high temperature-resistant and high pressure-resistant earthenware brick for a cylindrical shell entrance comprises a rectangular brick body. The rectangular brick body is divided into two parts from the middle. The rectangular brick body is provided with a circular hole along a thickness direction. The acid-resistant, high temperature-resistant and high pressure-resistant earthenware brick for a cylindrical shell entrance has wear resistance, fractures and spalls difficultly, has acid resistance and temperature shock resistance, has good corrosion-resistant lining effects, and is convenient for installation and replacement.

Description

technical field [0001] The invention relates to a lining product, in particular to a lining anticorrosion brick suitable for a nonferrous smelting zinc oxygen pressure leaching device. Background technique [0002] At present, the main equipment of oxygen pressure leaching in the metallurgical industry usually adopts "horizontal mechanical stirring autoclave", referred to as "horizontal autoclave". Its working principle is: the ore slurry enters from one end of the kettle, enters the next chamber from one chamber by overflow, and is discharged from the other end of the kettle, so that the pressure leaching operation realizes continuous operation. Each compartment is equipped with a stirring device, and the ore slurry in the tank is stirred by the rotation of the stirring paddle. Under the action of temperature, pressure and acidity, a series of gas-liquid-solid three-phase chemical reactions occur. Through the stirring effect of the stirring paddle, the contact of the mediu...
