Problems solved by technology

In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: due to the use of different stirring equipment in the stirring process, the problem of uneven mixing and stirring of different materials often occurs, and local over-humidity occurs in the process of adding liquid Or too dry, and the phenomenon of powder clusters appears, so that the prepared samples have congenital defects, and the obtained samples do not meet or do not meet the requirements of the experiment
No matter what kind of mixing method is used, a large number of dust particles will fly out during the mixing process. After adding liquid and stirring, a large amount of material will adhere to the mixing equipment, resulting in a certain amount of material loss; at the same time, there will be uneven mixing during the mixing process. Agglomeration and other phenomena, so the samples made must have certain differences, which directly affect the accuracy of the model test of similar materials; at the same time, during the stirring process, the quality of the feeding material, the uniformity of stirring and the stirring time cannot be accurately controlled, which affects the efficiency of sample preparation. and precision

Abstract

The invention discloses a full-automatic rock-like sample mixer and a mixing method capable of preventing dust and stirring uniformly. The mixer includes a support for supporting and fixing a cylinder body. A rotating shaft is installed on the axis, and the upper end of the rotating shaft is connected with the output shaft of the rotating motor. The rotating shaft is respectively fixed with a stirring device and a threaded stirrer from top to bottom. The inclination direction of the blades of the threaded stirrer is opposite to that of the stirring device. There is a solid storage hopper on the top of the cylinder, an annular nozzle is installed on the inner wall of the cylinder between the threaded agitator and the stirring device, and the discharge port is located at the bottom center of the cylinder; a solid particle electrode is installed inside the cylinder close to the stirring device. control sensor. The mixer of the invention prevents dust from escaping, improves mixing uniformity and prevents powder clusters during the mixing process, realizes fully automatic integration of feeding and mixing, improves sample preparation efficiency and precision, reduces sample residue, and ensures sample quality.

Description

technical field [0001] The invention belongs to the technical field of rock mechanics test devices, and relates to a full-automatic rock sample mixer and a mixing method capable of preventing dust from stirring uniformly, which can improve the uniformity of mixing, prevent dust from escaping during the process of feeding and stirring, and prevent powder clusters from appearing in the mixture . Background technique [0002] In the process of studying the physical mechanics of rock mass, due to defects such as cracks and joints in natural rock mass, high sampling cost, low production efficiency, and great randomness, it is often used to configure rock samples to study the original by analogy. rock material. In order to be able to simulate the real rock mass with a very wide variation range of strength, it is necessary to develop a similar rock-like model material with a wide range of physical and mechanical properties and stable performance control. The key to the success of...
