Oxidation tank with high material utilization

Abstract

The invention relates to an oxidation tank with a high material utilization rate, which comprises a cylindrical tank body and a platelike tank cover, wherein the cylindrical tank body is provided with an open upside; and the platelike tank cover is arranged at the open end of the tank body. The tank cover is provided with a slurry opening; an inclined bottom plate which forms a certain included angle with the bottom of the tank is arranged at the bottom of the tank body; and a discharge opening is formed on the side wall of the tank corresponding to a lower end of the bottom plate. The oxidation tank with the high material utilization rate is characterized in that a discharge pipe which is in threaded connection with the discharge opening and extends outwards is arranged at the discharge opening, and a filter screen which is vertical to the pipeline direction is arranged inside the discharge pipe. According to the oxidation tank with the high material utilization rate, solid and liquid materials are separated by the filter screen in the external discharge pipe, the solid materials are retained in a section of discharge pipe adjacent to one end of the discharge opening, and the discharge pipe is convenient to take down to take out the solid materials for cleaning. The slurry opening with the extension part extending into the tank can be further formed on the cover of the oxidation tank, so that the materials adhered to the tank body are reduced, and the utilization rate is further improved.

Description

technical field [0001] The invention relates to biological oxidation equipment in the fields of chemical industry and metallurgy, in particular to a vertical oxidation tank. Background technique [0002] Oxidation tank is a common equipment in wet smelting. There is a discharge port on the lower part of the side wall of the tank body. The traditional tank body has a conical bottom or a flat bottom, and the discharged material is easy to settle at the bottom of the tank, especially the conical head and the round bottom. The dead corner areas such as the edge cause waste of materials and difficulty in cleaning the bottom of the tank. Therefore, people set an inclined bottom plate at the bottom of the tank body to facilitate the flow of materials and fully discharge from the discharge port. However, the material usually includes solid and liquid at the same time, and it is directly discharged. The solid material will inevitably wear the wall of the discharge pipe with a long pi...

[0002] Oxidation tank is a common equipment in wet smelting. There is a discharge port on the lower part of the side wall of the tank body. The traditional tank body has a conical bottom or a flat bottom, and the discharged material is easy to settle at the bottom of the tank, especially the conical head and the round bottom. Dead corner areas such as edges cause waste of materials and difficulty in cleaning the bottom of the tank, so people set an inclined bottom plate at the bottom of the tank to facilitate the flow of materials and fully discharge from the discharge port

However, the material usually includes solid and liquid at the same time, and it is directly discharged. The solid material will inevitably wear the wall of the discharge pipe with a long pipeline outside the discharge port during the flow, and adhere to the wall of the pipe, resulting in a certain degree of material waste. It is inconvenient to clean the inside of the pipeline
