The invention relates to a high-pressure autoclave discharging hydraulic damping balance throttle control device. In the invention, high-pressure damping fluid and ore pulp pushed by the pressure in ahigh-pressure autoclave are respectively led into a closed device and interactionally fixed on two mesh-division impellers which are closely matched with a same rotating shaft and a device shell, anda damping fluid inlet and an ore pulp inlet are respectively arranged at two sides of a vertical surface of the rotating shaft; when the damping fluid and the ore pulp are injected into an empty chamber formed by the matching of the mesh-division impellers and the shell, the damping fluid and the ore pulp are respectively acted on the two impellers due to the pressure difference between the two groups of inlets and outlets in the device so as to form rotation moments which are equal in size and reverse in direction and drive the impellers to rotate, therefore, the whole rotating system is ina balanced state; the balance of the system is changed by the smaller moment when in discharging so that the ore pulp is injected when the empty chamber rotates to the ore pulp inlet position, and theore pulp is discharged when the empty chamber filled with the ore pulp rotates to the ore pulp outlet position from the ore pulp inlet; the moment for changing the balance of the system is eliminatedwhen the discharging stops, therefore, the impellers stops rotating, and the discharging stops.
Description
technical field [0001] The invention relates to an autoclave discharge hydraulic damping balance throttling control device belonging to the field of wet smelting, specifically a device for controlling and measuring the flow rate of ore pulp discharged from an autoclave in a mineral pressure leaching wet smelting operation. Methods and devices. Background technique [0002] Compared with the conventional atmospheric pressure hydrometallurgy process, the wet continuous pressure leaching technology is a continuous wet smelting process that enhances the leaching process by increasing the working pressure in the autoclave to obtain a higher reaction temperature. Because the operation process is carried out continuously. Therefore, during operation, it is required to control the flow rate of the ore pulp discharged from the kettle to be balanced with the flow rate of the ore pulp pressed into the autoclave. Change in a small range to make the leaching time of the pulp relatively...
