Description

Technical Field

[0001] The utility model belongs to the technical field of hydrometallurgical production, and in particular relates to a tubular filter liquid collecting device. Background Art

[0002] In the nickel-cobalt hydrometallurgical production process, the solution is usually purified by solvent extraction to meet the solution index requirements for producing battery-grade nickel sulfate or electrolytic nickel. However, the oil content of the raffinate has always been an important indicator limiting product quality. Currently, common oil removal methods include clarifiers, flotation, ultrasonic and activated carbon oil removal processes. For activated carbon oil removal, there is often a problem of activated carbon particle penetration. A small amount of activated carbon powder enters the pure nickel sulfate or cobalt sulfate solution, causing solution contamination and affecting the quality of subsequent electrolytic nickel or nickel sulfate products.

[0003] At present, the liquid after deoiling of activated carbon needs to be filtered through filter presses and precision filters to reduce the activated carbon powder entering the evaporation crystallization or electrolysis process. Large equipment such as filter presses and precision filters occupy a large area, require large equipment investment, are difficult to maintain, and have complex, time-consuming and labor-intensive installation steps. They are not convenient for simple filtration and are not suitable for production and use by small and medium-sized enterprises. Utility Model Content

[0004] The utility model aims to provide a tubular filter liquid collecting device to solve the problem of complex installation and high cost of large-scale equipment for filtering liquid after oil removal by activated carbon.

[0005] The technical solution of the utility model is: a tubular filter liquid collecting device, comprising a liquid collecting main pipe, a liquid collecting branch pipe and a support, a plurality of connecting pipes are respectively arranged on both sides of the liquid collecting main pipe, one end of the liquid collecting branch pipe is closed, and the other end is provided with a connecting end, the connecting end is detachably connected to the connecting pipe, a plurality of holes are opened through the outer circumference of the liquid collecting branch pipe, a filter layer is sleeved on the outer circumference of the liquid collecting branch pipe, and a plurality of gaps are evenly distributed on the filter layer, the support is annular, a first groove is symmetrically opened on the support, with the first groove as the center line, a plurality of second grooves are symmetrically opened on both sides of the support, the number of the second grooves, the liquid collecting branch pipes and the connecting pipes is the same, the liquid collecting main pipe is arranged in the first groove, and the liquid collecting branch pipes are arranged in the second groove.

[0006] As a further improvement of the utility model, the liquid collecting main pipe is divided into multiple sections, and each section is connected by flanges.

[0007] As a further improvement of the utility model, the connecting end is detachably connected to the connecting pipe via a thread.

[0008] As a further improvement of the utility model, the filter layer is formed by winding stainless steel on the liquid collecting branch pipe, and the winding gap of the stainless steel is 0.25-0.35mm.

[0009] The beneficial effects of the utility model are as follows: after the raffinate (nickel cobalt sulfate solution) after solvent extraction is deoiled by activated carbon, the solution is collected into the liquid collecting branch pipe through multiple holes through the gaps on the liquid collecting branch pipe, and the filter layer arranged on the periphery of the liquid collecting branch pipe effectively filters the filler particles through the evenly distributed gaps, and then the filtered solution enters the liquid collecting main pipe and is finally discharged to the deoiled liquid storage tank.

[0010] The utility model can be used to prevent filler particles such as activated carbon from entering the nickel sulfate or cobalt solution, thereby ensuring product quality requirements and reducing equipment investment and operation costs, thereby achieving the purpose of maintenance-free and reducing employee labor intensity.

[0011] The utility model can achieve the purpose of continuous long-term production operation, and solves the problems of large footprint, high equipment investment, high labor intensity and high operating costs of traditional large-scale filtering equipment. The utility model is simple to install and disassemble and maintenance-free, which improves production and operation efficiency and increases the economic benefits of small and medium-sized enterprises.

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1-Figure 4As shown, a tubular filter liquid collecting device comprises a liquid collecting main pipe 4, a liquid collecting branch pipe 1 and a support 6, a plurality of connecting pipes 5 are respectively arranged on both sides of the liquid collecting main pipe 4, the liquid collecting branch pipe 1 is closed at one end, and a connecting end 2 is arranged at the other end, and the connecting end 2 is detachably connected to the connecting pipe 5, a plurality of holes are opened through the outer periphery of the liquid collecting branch pipe 1, a filter layer 3 is sleeved on the outer periphery of the liquid collecting branch pipe 1, and a plurality of gaps 31 are evenly distributed on the filter layer 3, the support 6 is annular, a first groove 61 is symmetrically opened on the support 6, and a plurality of second grooves 62 are symmetrically opened on both sides of the support 6 with the first groove 61 as the center line, and the number of the second grooves 62, the liquid collecting branch pipe 1 and the connecting pipe 5 is the same, the liquid collecting main pipe 4 is arranged in the first groove 61, and the liquid collecting branch pipe 1 is arranged in the second groove 62.

[0019] The first groove 61 and the second groove 62 symmetrically provided on the support 6 form a circular sawtooth structure, so as to effectively fix the liquid collecting main pipe 4 and the liquid collecting branch pipe 1 .

[0020] The liquid collecting main pipe 4 is composed of multiple sections, each section is connected by a flange 7; the connecting end 2 is detachably connected to the connecting pipe 5 by a thread; it is convenient for installing and removing the liquid collecting main pipe 4 and the liquid collecting branch pipe 1, and it is convenient to set the quantity according to the use environment, making it more flexible and convenient to use.

[0021] The filter layer 3 is formed by winding stainless steel on the liquid collecting branch pipe 1, and the stainless steel winding gap 31 is 0.25-0.35mm.

[0022] Taking the arrangement of two sections of liquid collecting main pipes 4 and 8 liquid collecting branch pipes 1 as an example, the liquid collecting branch pipe 1 is a φ40 pipe with multiple holes running through the periphery to collect the feed liquid into the liquid collecting branch pipe 1. The outer peripheral wall of the liquid collecting branch pipe 1 is wrapped with 2.0 mm wide 316L stainless steel, and the evenly distributed gap 31 is 0.3 mm, thereby forming a filter layer 3 to prevent the activated carbon particles in the solution from entering the liquid collecting branch pipe 1.

Two connecting pipes 5 are symmetrically arranged on both sides of each section of the liquid collecting main pipe 4.

[0024] After the raffinate (nickel cobalt sulfate solution) after solvent extraction is deoiled by activated carbon, the solution passes through the 0.3 mm gap 31 on the peripheral filter layer 3 of the liquid collecting branch pipe 1. The uniformly distributed gaps 31 on the filter layer 3 effectively filter the filler particles in the solution. The filtered solution is collected into the liquid collecting branch pipe 1 through multiple holes on the liquid collecting branch pipe 1, slowly enters the liquid collecting main pipe 4, and finally discharged to the deoiled liquid storage tank, thereby effectively filtering the activated carbon particles in the solution.
