Description

Technical Field

[0001] This utility model relates to the technical field of flue ash cleaning liquid treatment, and in particular to a cleaning liquid conveying device for wet flue ash treatment. Background Technology

[0002] In metallurgical or certain chemical production processes, a large amount of soot is generated. This soot usually contains valuable metals (such as lead, zinc, cadmium, etc.) and harmful substances. Wet treatment, as one of the commonly used methods for treating soot, dissolves the valuable metals in the soot into a solution through leaching, stirring, and sedimentation, forming a clear liquid. This clear liquid, containing metal components, is then transported by a clear liquid conveying device to a subsequent process such as an electrolytic collection tank. The clear liquid after sedimentation inevitably has impurities floating on its surface, requiring effective filtration to remove them. Chinese utility model patent CN222907725U discloses a clear liquid conveying device that inputs the supernatant into a filter cylinder, where a cleaning roller cleans the inner wall of the filter cylinder. After filtration, the supernatant is discharged between a buffer tank and the filter cylinder. While this technical solution can adsorb some impurities in the supernatant using an adsorption rod, it suffers from the difficulty of replacing and cleaning the filter cylinder due to its large size. Therefore, we propose a clear liquid conveying device for wet soot treatment. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clear liquid conveying device for wet treatment of flue ash.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a clear liquid conveying device for wet treatment of flue ash, comprising an inlet conveying pipe, an outlet conveying pipe, and a liquid pump mechanism. The inlet conveying pipe is connected to the input port of the liquid pump mechanism, and the output port of the liquid pump mechanism is provided with an output conduit. A filter assembly is connected between the output conduit and the outlet conveying pipe. The filter assembly includes a protective tank and an inner filter cylinder. The inner filter cylinder is horizontally fixedly disposed within the protective tank. The liquid pump mechanism is fixedly installed on the upper side of the protective tank. The output conduit passes through the protective tank and is connected to the inlet port of the inner filter cylinder. The outlet conveying pipe passes through the protective tank and is connected to the outlet port of the inner filter cylinder.

[0005] To elaborate further, the internal filter cylinder includes a cylinder body and a cylinder head. The cylinder body is in the shape of a transverse cylinder. A detachable internal filter element is provided inside the cylinder body. The internal filter element is provided with an outer cylindrical frame and an inner filter screen. The inner filter screen is fixedly installed inside the outer cylindrical frame.

[0006] To further elaborate, one end of the outer cylindrical frame is provided with a pull ring portion, and the pull ring portion is provided with several through-holes. The lower end of the output conduit passes through the cylinder body and the through-holes at the pull ring portion, thereby transporting the clear liquid to the inner filter element for filtration. When the cylinder cover is placed on the cylinder opening of the cylinder body, the pull ring portion of the outer cylindrical frame abuts against the cylinder cover.

[0007] To elaborate further, a primary filter basket is provided at the inlet of the inner filter element, which is used to filter solid impurities with a particle size greater than 5 mm in the clear liquid.

[0008] To elaborate further, the outer cylindrical frame includes support plates arranged in a circumferential array, and several limiting rings are provided around the support plates. The mesh size of the inner filter screen is in the range of 500-600 mesh.

[0010] To elaborate further, a first switching valve is provided at the liquid inlet delivery pipe, and a second switching valve is provided at the liquid outlet delivery pipe. The first switching valve and the second switching valve have the same structure.

[0011] The beneficial effects of this utility model are as follows: This utility model adopts a structural design that combines a liquid pump mechanism with a filter assembly. The liquid pump mechanism pumps the clear liquid in the ash sedimentation tank into the filter assembly through the liquid inlet delivery pipe. The inner filter cylinder of the filter assembly filters the pumped clear liquid, thereby removing solid particles and floating impurities from the clear liquid. Furthermore, the inner filter element can be directly pulled out from the cylinder for easy replacement and cleaning, and it has wide applicability. Attached Figure Description
