Description

Technical Field

[0001] This utility model relates to the field of purification equipment, and in particular to a graphene oxide purification equipment. Background Technology

[0002] Graphene oxide is the oxidized form of graphene, possessing abundant oxygen-containing functional groups such as hydroxyl, epoxy, carboxyl, and carbonyl groups. These functional groups endow graphene oxide with excellent chemical stability, making it a promising candidate for applications in composite materials, sensors, energy storage, and environmental remediation.

[0003] In industrial production, the oxidative intercalation method can produce graphene oxide on a large scale. However, the graphene oxide solution produced by the oxidative intercalation method contains a large number of impurity ions. In the current purification process of graphene oxide, the graphene oxide solution and the binder are generally mixed by stirring and mixing, and then the impurities are filtered for purification. However, stirring the mixed solution by stirring shaft has the problems of low efficiency and poor effect, resulting in low quality of graphene oxide produced.

[0004] Therefore, those skilled in the art have provided a graphene oxide purification apparatus to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a graphene oxide purification device. Two screens are slidably installed inside the filter box. When the upper screen is damaged, the lower screen ensures normal operation of the device. The output end of the rotating motor is connected to the rotating shaft. Two filter discs are fixed to the upper surface of the rotating shaft. When the graphene solution and binder enter the filter discs, the discs rotate, causing the graphene solution and binder to mix as they flow downwards.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphene oxide purification device, comprising a mixing device, wherein a first control valve is fixedly disposed on the lower end face of the mixing device, a filter module is fixedly disposed on the lower end face of the first control valve, the mixing device includes a mixing box, and a protective box is fixedly disposed on the upper end face of the mixing box;

[0007] A rotating motor is fixedly installed on the bottom surface of the protective box, and a rotating shaft is fixedly installed at the output end of the rotating motor. Two filter discs are fixedly installed on the upper surface of the outer surface of the rotating shaft. The filter module includes a filter box, and two filter screens are slidably installed inside the filter box.

[0008] Furthermore, a fixing surround is fixedly provided at the lower end of the outer surface of the mixing device, and a support plate is fixedly provided at the lower end face of the fixing surround.

[0009] Furthermore, support columns are fixedly installed at the four corners of the lower end face of the support plate, and a cabinet door is hinged to the front end face of the filter module.

[0010] Furthermore, a first nozzle is fixedly provided on the upper surface of the mixing tank, and a first liquid inlet is fixedly provided on one side of the first nozzle.

[0011] Furthermore, a second nozzle is fixedly provided on the upper end of the outer surface of the mixing tank, and a second liquid inlet pipe is fixedly provided on the other side of the second nozzle.

[0012] Furthermore, a stirring head is fixedly provided at the lower end of the outer surface of the rotating shaft, and a stirring box is fixedly provided at the lower end face of the mixing box.

[0013] Furthermore, a second control valve is fixedly installed on the lower end face of the filter box, and a support cover is fixedly installed on the upper end face of the filter box.

[0015] 1. This utility model proposes a graphene oxide purification device. During use, the mixing device can mix graphene solution and binder. The mixing device includes a mixing tank, in which the graphene solution and binder can be mixed. A protective box is fixed on the upper surface of the mixing tank to protect the rotating motor. The output end of the rotating motor is connected to the rotating shaft. Two drain plates are fixed on the upper surface of the outer surface of the rotating shaft. When the graphene solution and binder enter the drain plates, the rotating motor starts to rotate the drain plates, so that the graphene solution and binder are mixed as they flow downwards. Compared with simple stirring and mixing, the effect is better.

[0016] 2. The graphene oxide purification device proposed in this utility model, after the graphene solution and binder are mixed in the mixing device, can enter the interior of the filtration module. The filtration module includes a filter box, inside which two screens are slidably installed to filter impurities in the solution. The screens slide inside the filter box. When the upper screen is damaged, the lower screen can ensure the normal operation of the equipment. When the screen is damaged, it can be pulled out from the filter box for replacement.

The filtration module 3 can filter out impurities in the solution and export the filtered solution, allowing it to combine with deionized water to form a graphene hydrogel. The graphene hydrogel is then placed in a freeze-drying thermostatic appliance for further processing to purify the graphene.

The lower end of the rotating shaft 110 is fixed to the stirring head 102, so that the strainer plates 103 and the stirring head 102 can rotate when the rotating shaft 110 rotates. A first nozzle 105 is provided on the upper surface of the mixing chamber 101. A first inlet 104 is located on one side of a nozzle 105.

A second nozzle 108 is fixed to the mixing tank 101 and connected to a second inlet pipe 109, which can spray binder into the interior of the mixing tank 101. When the graphene solution and binder enter the interior of the mixing tank 101, the rotating motor 107 drives the drain plate 103 to rotate, so that the graphene solution and binder can be mixed when flowing downwards. When it flows into the mixing box 111, the rotating shaft 110 causes the stirring head 102 to stir the mixture inside the mixing box 111 again.

[0029] Specifically, the filter module 3 is equipped with a filter box 301 inside. The filter box 301 allows the screen 302 to slide inside. The screen 302 can filter the liquid entering the filter box 301 and filter out the impurities inside the liquid. After use, the screen 302 can be pulled out and cleaned. A second control valve 304 is fixedly installed on the lower end face of the filter box 301. The second control valve 304 can discharge the filtered solution. The support cover 303 can connect the filter module 3 and the first control valve 2.

[0030] Working principle: The graphene solution is introduced into the mixing device 1, and then citric acid and dilute hydrochloric acid are combined as a binder and introduced into the mixing device 1 so that the graphene solution can be mixed with the binder, and the impurities in the solution can be bound by the binder.

[0031] The mixing device 1 has a mixing tank 101, and a protective box 106 at the upper end of the mixing tank 101. The protective box 106 can protect the rotating motor 107. The rotating motor 107 is connected to the rotating shaft 110. When the rotating motor 107 is started, the rotating shaft 110 can be rotated. Two drip trays 103 are provided on the upper end of the outer surface of the rotating shaft 110. The first nozzle 105 can spray the graphene solution into the interior of the mixing tank 101, and the second nozzle 108 can spray the binder into the interior of the mixing tank 101. The rotating motor 107 drives the drip trays 103 to rotate, so that the graphene solution and the binder can be mixed when flowing downwards.
