Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles and relates to a telescopic metal gallium purification liquid extraction device. Background Art

[0002] Gallium metal is a precious rare metal, located in the 13th group of the periodic table. It is a poor metal with similar properties to aluminum, indium and thallium. It is golden yellow, has a metallic luster, a low melting point and a high boiling point. It is soluble in aqua regia and potassium cyanide, and insoluble in acid, cold water and hot water. At present, gallium metal mainly comes from bauxite, which is mainly a by-product of alumina production, accounting for 90% of the current gallium production. The main product extracted from the mother liquor of alumina production is industrial crude gallium. Due to the high impurity content and low added value in crude gallium, its application is limited. It is necessary to further purify the crude gallium to obtain high-purity gallium.

[0003] During the purification of metallic gallium using a reactor, an acid cleaning agent is added to the reactor to dissolve impurities in the crude gallium. However, during the separation of the cleaning agent after cleaning, the metallic gallium and the cleaning agent have always been discharged from the reactor together and placed in a specific container for manual precipitation separation. During the manual cleaning and separation process, the work efficiency is low, which brings a large workload to the cleaning agent separation link and easily causes acid and alkali burns to personnel during work. Utility Model Content

[0004] The utility model aims to provide a retractable metal gallium purification liquid extraction device, which is used to solve the problems of low work efficiency, large workload and easy acid and alkali burns in the separation process when the liquid after cleaning by cleaning agent is separated manually in the prior art.

[0005] The technical solution adopted by the utility model is a retractable metal gallium purification liquid extraction device, comprising a reactor and a retractable device; the retractable device comprises a drainage tube of an external rack and a gear; an opening for the drainage tube to pass through is opened on the top of the reactor, one end of the drainage tube extends into the reactor, and the other end extends out of the reactor, and the end extending out of the reactor is meshed with the gear through the external rack.

[0006] Furthermore, the telescopic device also includes a rocker with an external rack meshing with the gear.

[0007] Furthermore, one end of the drainage tube extending out of the reactor is connected to the liquid inlet of the diaphragm pump through a telescopic hose.

[0008] Furthermore, the liquid outlet of the diaphragm pump is connected to a waste liquid collection bucket.

[0009] Furthermore, the outer wall of the reactor is also provided with a visual window.

[0010] Furthermore, the telescopic device is fixed to the top of the reactor through the outer shell.

[0011] Furthermore, the reactor further comprises a stirring device, which comprises a stirrer arranged in the reactor and a stirring motor arranged outside the reactor. The stirrer and the stirring motor are connected via a stirring shaft.

[0012] Furthermore, a cleaning agent inlet is provided on the top of the reactor.

[0013] Furthermore, the outer wall of the reactor is also provided with a jacket structure for controlling the reactor temperature.

[0014] The beneficial effects of the utility model are as follows: when the device extracts the liquid to be separated in the reactor, the extraction is performed through the gears and the drainage tube installed on the reactor. When the liquid is extracted, the gear meshing transmission drives the drainage tube to extend into the reactor, thereby draining the liquid in the reactor. Since the depth of the drainage tube entering the reactor can be adjusted by the gear, the upper layer liquid at different heights can be extracted with different extension lengths of the drainage tube, and the flow rate is controllable. The process is simple to operate and the liquid extraction accuracy is higher. The utility model can reduce the risk of acid and alkali corrosion and burns to equipment or personnel during operation, and improve the work efficiency of cleaning agent separation in the gallium metal refining and washing process.

The outer surface of the rocker 16 also has a threaded structure, which is meshed with the gear 17. When the rocker 16 rotates, it drives the gear 17 to rotate, and then drives the extension length of the drainage tube 15 in the reactor. The extension length is precisely adjustable, and the operation is simple and convenient.

[0022] In order to better fix the telescopic device 7 on the top of the reactor 3, the telescopic device 7 is fixed on the reactor 3 through the outer shell.

[0024] The device of this embodiment also includes a stirring device, which includes an agitator 9 arranged inside the reactor 3 and a stirring motor 11 arranged on the top of the reactor 3. The agitator 9 is connected to the stirring motor 11 through a stirring shaft, and the stirring motor 11 drives the agitator 9 to rotate in the reactor 3 through the stirring shaft.

[0025] The outer wall of the reactor 3 is also provided with a sight glass 8, through which the liquid level and stratification of the detergent in the reactor 3 can be observed, and the telescopic amount of the telescopic device 7 can be adjusted according to the liquid level and stratification of the detergent in the reactor 3; the outer wall of the reactor 3 is also provided with a jacket structure 10, through which heat exchange can be carried out to control the reactor temperature.

[0027] The drainage tube 15 of this embodiment is made of polytetrafluoroethylene; the reactor 3 is an enamel reactor, which is suitable for complex acid-base environments; the pipeline between the diaphragm pump 13 and the quick connector 12 is a telescopic hose; the diaphragm pump 13 has an adjustment structure to control the flow rate of the extracted liquid, and a small diaphragm pump 13 is used in this embodiment, which is small in size and easy to move, does not require a foundation, occupies a very small area, is easy and economical to install, and can transport corrosion-resistant liquids.

[0028] The implementation process of this device is as follows:

[0029] Step 1: After the cleaning agent enters the reactor through any one or two cleaning agent inlets to clean the metal gallium, the extension length of the polytetrafluoroethylene drainage tube is manually adjusted by observing the sight glass 8 of the reactor 3 until the polytetrafluoroethylene drainage tube reaches the required height.

[0030] Step 2: Connect the quick connector 12 on the polytetrafluoroethylene drainage tube to the quick connector of the liquid inlet pipe of the diaphragm pump 13.
