Microbubble gun with automatic fault detection and detection and control method

Abstract

The invention provides a microbubble gun with an automatic fault detection function and a detection and control method. The microbubble gun with the automatic fault detection function comprises a gun body. The gun body comprises an outer tube, an inner rod and a diaphragm bin. The inner rod is mounted in the outer tube. A spray opening in the front end of the outer tube is sealed by a plug at the front end of the inner rod. An airflow passageway is formed by a gap between the inner rod and the outer tube. The rear end of the outer tube is mounted at the front end of the diaphragm bin in a sealed manner. A rear inner tube communicating with high-pressure gas is mounted at the rear end of the diaphragm bin in a sealed manner. An electronic control box is mounted in the diaphragm bin. An air outlet of the rear inner tube communicates with an air inlet of the airflow passageway through the electronic control box. An alarming device powered by the electronic control box is arranged on the diaphragm bin. By the adoption of the microbubble gun with the automatic fault detection function and the detection and control method, it is guaranteed that the fault can be found in time when the microbubble gun fails, so that the microbubble gun can be replaced in time, the phenomena of the insufficient inflating and non-uniform inflating of a flotation column are avoided, the flotation indexes can be controlled continuously, effectively and stably, and the influence of the fault of the microbubble gun on the indexes of the flotation column is reduced.

Description

technical field [0001] The invention belongs to mineral processing equipment, in particular to an automatic fault detection microbubble gun and a detection and control method. Background technique [0002] The microbubble gun (some called the microbubble generator) is one of the core components of the flotation column, which directly affects the quality of the flotation operation indicators. The micro-bubble gun uses the high-speed jet formed by high-pressure air to act on the pulp and split to form tiny bubbles. Therefore, it will drive the pulp to form a high-speed flow at the nozzle, and the high-speed flow of pulp will cause wear to the nozzle, and the high-speed airflow forms The cavitation phenomenon of the microbubble gun makes the nozzle of the microbubble gun easy to be damaged, which may cause the microbubble gun to not block the nozzle normally when the machine is shut down, so that the slurry seeps in and causes the microbubble gun to be blocked. However, in act...

Problems solved by technology

The micro-bubble gun uses the high-speed jet formed by high-pressure air to act on the pulp and split to form tiny bubbles. Therefore, it will drive the pulp to form a high-speed flow at the nozzle, and the high-speed flow of pulp will cause wear to the nozzle, and the high-speed airflow forms The cavitation phenomenon of the microbubble gun makes the nozzle of the microbubble gun easily damaged, which may cause the microbubble gun to fail to block the nozzle normally when the machine is shut down, resulting in the infiltration of ore slurry, resulting in the blockage of the microbubble gun

However, in actual production, there are many factors that can cause this kind of clogging and affect the normal work of the microbubble gun.

Since the micro-bubble gun is directly inserted into the pulp, its working status is difficult to grasp intuitively, which makes it difficult for the on-site staff to find out the micro-bubble gun that has failed in time. When the mineral processing index is found to be abnormal, the loss will be considerable. , Moreover, even if abnormal indicators are found, it cannot be determined that it is a problem with the microbubble gun.
