Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning systems, in particular to an alkali cleaning system for alumina plant trenches. Background Art
[0002] There are many trenches at the alumina production site, which are used for pumping equipment or process discharge. The materials enter the sewage tank through the trench, and then the sewage pump is used to re-add the materials to the process, which reduces material waste on the one hand and reduces environmental problems caused by external discharge on the other hand. The trenches are prone to material accumulation and scarring during long-term discharge, affecting on-site use or causing on-site material overflow due to poor material flow, which creates a lot of workload for on-site personnel and also brings some safety hazards. To address this phenomenon, employees often use mechanical tools to physically remove the accumulated materials or scars, which is a large workload and can easily cause personal injury during the operation. Utility Model Content
[0003] The main purpose of the utility model is to provide an alkali cleaning system for an alumina plant trench, so as to solve the problem in the prior art that the removal of accumulated materials or scars in the trench is labor-intensive and easily causes personal injury.
[0004] In order to achieve the above-mentioned purpose, the utility model provides an alkali cleaning system for an alumina plant ditch, comprising a ditch, a sewage trough connected to the ditch, and a chemical cleaning trough, wherein the outlet of the chemical cleaning trough is connected to a chemical cleaning pump, and the outlet of the chemical cleaning pump is connected to the ditch through a pipe 1; the sewage trough is connected to the sewage pump through a pipe, and the outlet of the sewage pump is connected to the chemical cleaning trough through a pipe 2.
[0005] Furthermore, a heating pipe is provided inside the cleaning tank.
[0006] Furthermore, the outlet of the chemical cleaning pump is connected to a leaf filter through pipeline three, the leaf filter is connected to the chemical cleaning tank through a pipeline, and valves are connected to pipeline one and pipeline three.
[0007] Furthermore, the outlet of the sewage pump is also connected to a discharge pipe and a recovery pipe, and valves are connected to pipeline 2, the discharge pipe and the recovery pipe.
[0008] The utility model connects the chemical cleaning tank with the sewage tank, prepares alkali solution in the chemical cleaning tank, and uses a pump to circulate the alkali solution, thereby achieving alkali cleaning of accumulated materials and scars in the chemical cleaning tank. Compared with mechanical removal, alkali cleaning has higher efficiency and better removal effect, and avoids injury to personnel. The chemical cleaning tank is the original tank for providing alkali solution for alkali cleaning of the leaf filter, and the sewage pump and the chemical cleaning pump are also existing. There is no need to build a new tank or purchase a new pump, so the chemical cleaning tank can be used for multiple purposes, and the sewage pump and the chemical cleaning pump can be used for multiple purposes, thereby reducing costs.
