Embodiment approach

[0050] As an embodiment of the present invention, refer to Figure 4 , the first drive mechanism includes a mounting bracket 23 that is fixedly installed in the funnel 20 horizontally. A reciprocating screw rod 26 is vertically fixedly installed on the top of the reciprocating screw rod 26, a slider 27 is threadedly installed on the reciprocating screw rod 26, and two top rods 28 that cooperate with the second filter plate 21 are vertically fixed and installed on the top wall of the slider 27. A second installation rod 46 is fixed horizontally on the inner wall of the funnel 20 , and a telescopic rod 47 whose output end is fixedly connected to the side wall of the slider 27 is vertically fixed and installed on the second installation rod 46 .

[0051] In the initial state, under the action of gravity, the bottom wall of the second filter plate 21 is in contact with the top of the reciprocating screw rod 26. During the working process, the liquid passing through the first filte...

Abstract

The invention relates to the technical field of sulfuric acid production, in particular to an industrial sulfuric acid solid-liquid separation system which comprises a workbench, an air drying box, a filter box and a transfer box are sequentially and fixedly mounted on the top wall of the workbench from left to right, a guide pipe extending into the filter box is fixedly mounted on the side wall of the transfer box, and a valve is mounted on the guide pipe. Under the action of gravity, liquid flowing out of the guide pipe falls onto the first filter plate, at the moment, the liquid penetrates through the first filter plate and enters the liquid accumulation box, filter residues remain on the surface of the first filter plate, and due to the fact that the first filter plate is obliquely installed, the filter residues are not prone to falling off. Therefore, the filter residues gradually slide into the flow guide pipe along the surface of the first filter plate and move to the surface of the filter screen along the flow guide pipe, after the filter residues are air-dried on the surface of the filter screen, the filter residues enter the filter residue box under the action of the feeding mechanism, and solid-liquid separation is carried out on liquid in the whole process.

Description

technical field [0001] The invention relates to the technical field of sulfuric acid production, in particular to an industrial sulfuric acid solid-liquid separation system. Background technique [0002] In the process of making acid from pyrite, due to the large amount of waste residue produced by roasters and waste heat boilers, the solid waste produced by pyrite acid production, namely high-temperature roasting slag, has always been a problem that plagues production management, site management and comprehensive management of environmental protection. The main reason is that the roasting slag produced by the roaster and the waste heat boiler has a high temperature (850℃-1100℃) and a fine particle size (200mesh-500mesh). The original treatment methods are mostly hydraulic slag flushing or direct slag treatment Water drenching and humidification will cause multiple pollution of dust and water, steam and dust on the production site. Due to the large amount of acidic substance...
