Description

Technical Field

[0001] This utility model relates to the field of solvent extraction technology in hydrometallurgy, and in particular provides a device for extracting suspended three-phase sludge from a solvent extraction clarification chamber. Background Technology

[0002] In the extraction stage of hydrometallurgical processes, solid impurities, chemical deposits, colloidal substances, and suspended particles left over from upstream leaching processes are easily carried into the extraction system, mixing with organic solvents and aqueous solutions to form a complex three-phase mixture. In the extraction mixing chamber, due to the continuous flow of the organic phase, the three-phase mixture tends to accumulate and be compressed at the oil-water interface. As the density increases, these three-phase mixtures eventually settle to the bottom of the clarification chamber, forming a so-called bottom three-phase layer. If the thickness of this layer exceeds a critical value, it may be pushed over the weir by the aqueous phase, causing a series of problems. The significant presence of the three-phase mixture disrupts the operating parameters of the extraction system, increases the consumption of extraction solvent and diluent, and may be carried into the aqueous phase as impurities, adversely affecting subsequent processing flows.

[0003] The current industry standard of manual sieving is labor-intensive, inefficient, and unable to comprehensively cover all areas, achieving only localized cleaning. Furthermore, this method is prone to significant disturbance during operation, affecting the stability control of the extraction process. For long-running extraction systems, large amounts of three-phase contaminants may accumulate at the bottom, which are difficult to remove immediately during production. Thorough manual cleaning requires system shutdown and drainage of the internal medium, a process that is not only labor-intensive and challenging but also directly disrupts production, reducing economic efficiency. Moreover, both the interfaces and the bottom of the system pose a risk of leakage during manual retrieval and transfer of three-phase contaminants, potentially polluting the surrounding environment and creating safety hazards. Therefore, exploring more efficient and environmentally friendly three-phase contaminant cleaning and treatment technologies is crucial for improving the overall efficiency and sustainability of hydrometallurgical extraction processes.

[0004] Based on this, the present invention provides a solvent extraction clarification chamber suspended three-phase contaminant extraction device, which can comprehensively and accurately extract the three-phase contaminants at the phase interface and bottom of the extraction clarification chamber, reducing the tediousness and time consumption of manual repeated retrieval, and improving the safety of cleaning work.

[0005] To achieve the above objectives, this utility model provides a solvent extraction clarification chamber suspended three-phase contaminant extraction device, including a floating frame, a supporting beam, a three-phase extractor, and a liquid level adjustment mechanism. The floating frame has a sealed buoyancy cavity inside, and the supporting beam is connected to the middle of the floating frame.

[0006] Furthermore, the three-phase extractor includes an extraction pump, and the extraction pipeline includes a vertical pipe. The suction pipe of the extraction pump is connected to the outlet at the upper end of the vertical pipe, and the suction end is located at the bottom of the vertical pipe. The extraction pump is a diaphragm pump or a flexible hose pump. The suction port of the extraction pump is connected to the upper end of the vertical pipe through a flexible hose, and the discharge port is connected to a storage tank or reservoir.

[0007] Furthermore, the extraction pipe also includes a horizontal pipe, which is connected to the bottom of the vertical pipe in the middle and sealed at both ends. The side wall of the horizontal pipe is provided with multiple turbulent inlets that extend laterally and are of the same height.

[0008] Furthermore, the liquid level regulating mechanism includes an regulating cylinder, the cylinder body of which is fixedly mounted on a crossbeam, and the movable rod extends upward and connects to the vertical pipe of the three-phase extractor. The regulating cylinder is an electric telescopic cylinder or an electric push rod, and the controller connected to the regulating cylinder is equipped with a remote control handle.

[0009] Furthermore, the liquid level regulating mechanism also includes a guide sleeve, which is fixedly mounted on the support beam and extends vertically, and the vertical pipe is movably installed inside the guide sleeve.

[0010] Furthermore, the liquid level adjustment mechanism includes fasteners, including but not limited to tightening or clamping components, and the vertical tube of the three-phase extractor is movably installed in the guide sleeve and its height position is fixed by fasteners.

[0022] The following description, along with the accompanying drawings and text, will help you understand the content of this utility model and the differences between it and the prior art. The technical solution (including preferred solutions) of this utility model will be further described in detail below through the accompanying drawings and by listing some optional embodiments.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a solvent extraction clarification chamber suspended three-phase contaminant extraction device, including a floating frame 1, a supporting beam 2, a three-phase extractor 6, and a liquid level adjustment mechanism 3. The floating frame 1 has a sealed buoyancy cavity inside, and the supporting beam 2 is connected to the middle of the floating frame 1. The three-phase extractor 6 is equipped with an extraction pipe 4, the suction end of which is located below the supporting beam 2. The liquid level adjustment mechanism 3 is mounted on the movable beam and connected to the extraction pipe 4, allowing the liquid level adjustment mechanism 3 to adjust the suction end of the three-phase extractor 6 to different depths, thereby extracting the interphase and bottom three-phase contaminants from the clarification chamber.

[0024] In implementation, the three-phase extractor 6 includes an extraction pump, and the extraction pipeline 4 includes a vertical pipe. The suction pipe 5 of the extraction pump is connected to the upper end of the vertical pipe, and the suction end is located at the bottom of the vertical pipe. The extraction pipeline also includes a horizontal pipe, which is connected to the bottom of the vertical pipe in the middle and sealed at both ends. The side wall of the horizontal pipe is provided with multiple laterally extending turbulent suction ports 7 at the same height. The extraction pump is a diaphragm pump or a flexible hose pump. The suction port of the extraction pump is connected to the upper end of the vertical pipe through a flexible hose, and the discharge port is connected to a storage tank or container.

[0025] The floating frame 1 is a planar frame structure with pipe connections. The supporting beam is connected inside the planar frame structure. The pipe is made of PE, PP or stainless steel. The inner cavity of the pipe is sealed to form a buoyancy cavity.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the liquid level adjustment mechanism 3 includes an adjustment cylinder 8. The cylinder body of the adjustment cylinder 8 is fixedly mounted on the crossbeam, and the movable rod extends upward and is connected to the vertical tube of the three-phase extractor 6. In implementation, the adjustment cylinder 8 is an electric telescopic cylinder or an electric push rod, and the controller connected to the adjustment cylinder 8 is equipped with a remote control handle. The liquid level adjustment mechanism 3 also includes a guide sleeve, which is fixedly mounted on the supporting crossbeam 2 and extends vertically. The vertical tube is movably installed inside the guide sleeve. By using the adjustment cylinder 8, the depth of the suction end can be dynamically adjusted during the extraction process without needing to be done on the ground, thus achieving flexibility in adjustment and improving extraction efficiency.

[0027] like Figure 3 As shown, in another embodiment, the liquid level adjustment mechanism 3 includes fasteners, including but not limited to tightening or locking components. The vertical tube of the three-phase extractor 6 is movably installed within a guide sleeve and its height is fixed by the fasteners. During implementation, the height of the vertical tube can be manually adjusted from the ground, and the position is then fixed by the fasteners.

[0028] Operating method using the provided extraction device:

[0029] Before starting the operation, place the suspended three-phase sludge extraction device into the extraction and clarification chamber. Because the pipes that make up the floating frame 1 are hollow and well-sealed, the entire device can float on the liquid surface. Secure the pull rope to the floating frame 1 so that the device can operate in all areas of the clarification chamber. Secure the inlet pipe of the extraction pump to the outlet 5 at the top of the three-phase extraction device 6 to complete the preparation work.

[0030] The position of the three-phase layer in the solution is determined by manual observation and test tube method. After determining the position, the extraction pipe 4 at the top of the three-phase extraction device 6 is adjusted by loosening the liquid level adjustment mechanism 3, so that the turbulent inlet 7 of the extraction device 6 is placed in the three-phase layer in the solution. After adjustment, the adjustment mechanism 3 is tightened.

[0031] When the extraction pump is turned on, the three phases in the solution will enter from the turbulent inlet 7, pass through the extraction pipe 4 and the outlet 5, and enter the inlet pipe of the extraction pump. After being pumped to the rear storage tank, the three-phase transfer operation is completed.

[0032] Based on the provided extraction device, the floating frame 1 floats on the liquid surface. The suspension design of the suction end of the three-phase material extractor 6 allows the suction end of the three-phase material extractor 6 to be adjusted to different depths by the liquid level adjustment mechanism 3. This extracts the interphase and bottom three-phase contaminants in the clarification chamber, achieving comprehensive and accurate extraction of the three-phase contaminants at the phase interface and bottom of the extraction clarification chamber. The equipment is easy to assemble and maintain on-site. Operators only need to start the equipment to automatically complete the cleaning work, effectively reducing the tediousness and time-consuming manual repeated retrieval and significantly improving work efficiency.

[0033] In practical implementation, an innovative solvent extraction clarification chamber suspended three-phase sludge extraction device is provided. This device integrates a floating frame 1, a stable supporting beam 2, a precise liquid level adjustment mechanism 3, and a high-efficiency three-phase extractor 6. The floating frame 1 is made of corrosion-resistant lightweight, high-strength materials such as PE, PP, or HDPE, ensuring stable buoyancy and durability of the device during operation.

[0034] A liquid level adjustment mechanism 3 is cleverly installed on the supporting beam 2. This design allows the three-phase material extractor 6 to flexibly adjust its working depth and accurately position itself on the three-phase contaminants at different liquid levels, achieving precise cleaning. Through the seamless connection between the extraction pump and the three-phase material extractor 6, the contaminants can be efficiently and smoothly transferred out of the clarification chamber, avoiding the limitations and shortcomings of traditional methods.

[0035] This eliminates the need for operators to enter the area above the extraction and clarification chamber, thus removing potential safety hazards such as falls, drowning, and chemical burns caused by personnel activity and significantly improving workplace safety. Furthermore, the waste is directly transported to a dedicated storage tank through a closed pipeline after extraction, effectively reducing the risk of leakage during the transfer process and demonstrating good environmental friendliness.

[0036] In terms of ease of operation, the provided extraction device is specially equipped with a pull rope system. Operators can easily move the entire device to the designated work area by simply pulling the rope, further improving work efficiency. Meanwhile, the flexible application of the liquid level adjustment mechanism 3 allows the cleaning of three-phase contaminants to no longer be limited to specific locations or depths, achieving a comprehensive and thorough cleaning effect. In summary, the provided suspended three-phase contaminant extraction device not only significantly improves work efficiency but also greatly enhances operational safety, improves the working environment, ensures stable system operation, and has relatively low manufacturing costs, making it highly economical and worthy of widespread application. Example

[0037] At a domestic extraction-electrowinning smelter with an annual output of 40,000 tons, the high solid content in the pre-extraction liquid during the pretreatment stage directly led to the formation of a large amount of emulsion-like three-phase material within the extraction system. This material was mainly concentrated at the interface between the aqueous and oil phases. Traditional manual removal methods are not only extremely labor-intensive and inefficient, but also only achieve localized cleaning, while the extensive agitation poses a threat to the stability of the extraction process. Furthermore, the risk of leakage during transport cannot be ignored, as it pollutes the environment and increases safety hazards.

[0038] To address the aforementioned issues, the smelter improved its operating method by using this patented automatic three-phase sludge extraction device. This device can be easily moved to different work points via a simple pull-rope operation. Combined with the liquid level adjustment mechanism 3, the working depth of the three-phase extractor is precisely controlled, achieving comprehensive cleaning. More importantly, by connecting to a diaphragm pump to complete a closed-loop transfer, the three-phase sludge can be safely and efficiently transported to a storage tank for subsequent processing, effectively preventing leakage. The application of this innovative technology has greatly reduced the labor intensity of workers, improved the working environment, and successfully reduced the number of three-phase sludge removal personnel in the workshop from 15 to 4. Example

[0039] In a foreign hydrometallurgical plant with an annual output of 25,000 tons, the high concentration of solids in the liquid before extraction led to a significant increase in emulsified three-phase matter within the extraction system over a long period. Furthermore, due to the lack of systematic maintenance for two consecutive years, a large amount of three-phase matter accumulated at the bottom of the clarification chamber. Traditional cleaning methods face numerous challenges in addressing this situation: cleaning operations require production shutdowns, manual labor at the bottom of the clarification chamber is time-consuming, arduous, and inefficient, directly weakening the company's production capacity and economic benefits; simultaneously, the risk of leakage during transfer poses a serious threat to the environment and safety.

[0040] To overcome the aforementioned challenges, the plant introduced an advanced automatic three-phase suspended waste extraction device. This device allows for comprehensive cleaning of the three-phase materials in the clarification chamber during normal production line operation by flexibly adjusting its position and working depth. It operates efficiently without production stoppages, ensuring production continuity and the company's economic benefits. Furthermore, combined with a hose pump and a closed-loop transfer system, the three-phase waste can be safely and leak-free transported to a storage tank for separation, effectively reducing environmental pollution and safety risks.

[0041] After implementing this device, the cleanup work that previously required 20 people and approximately 15 days can now be completed by only 2 operators, significantly reducing labor costs and improving operational efficiency. Simultaneously, the closed-loop transfer mechanism ensures zero leakage during the transfer process, further improving the working environment and reducing the workload of staff. In summary, this automatic suspended three-phase sludge extraction device demonstrates significant advantages in improving production efficiency, ensuring environmental safety, and improving working conditions.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
