[0029] A gold powder washing and filtering device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] Reference Figure 1 The present invention aims to provide an embodiment of a gold powder washing and filtering device.

[0031] A gold powder washing and filtering device according to an embodiment of the present invention includes a barrel 100, a turning component and a filtering component disposed in the barrel 100. The barrel 100 contains gold powder and washing liquid. The turning component is used to turn the gold powder in the barrel 100, and the filtering component is used to filter the gold powder in the barrel 100.

[0032] Among them, reference Figure 2 and Figure 3 The tub 100 has a first tilted state and a second tilted state. The tub 100 can be rotated between the first tilted state and the second tilted state. The interior of the tub 100 has a washing area and a filtering area. The washing area and the filtering area are arranged sequentially along the flipping direction of the tub 100. When the tub 100 is in the first tilted state, the washing area is located below the filtering area. When the tub 100 is in the second tilted state, the filtering area is located below the washing area.

[0033] It is understood that this utility model, by having the barrel 100 in a first tilted state and a second tilted state, rotates the barrel 100 at a certain angle, causing the barrel 100 to tilt at a certain angle. In the first tilted state, the washing liquid and gold powder can flow and gather in the washing zone, where the gold powder undergoes washing processing. After washing, the barrel 100 rotates in the opposite direction at a certain angle, causing the barrel 100 to tilt in the opposite direction at a certain angle, causing the barrel 100 to be in the second tilted state. In this second tilted state, the washing liquid and gold powder can flow and gather in the filtration zone, where the washing liquid and gold powder undergo solid-liquid separation. Thus, the washing and filtration processes are carried out in different areas, reducing the continuous friction between the gold powder and the filter plate 130 during washing and drying, extending the life of the filter plate 130, and reducing production costs.

[0034] In some embodiments of this utility model, the inner cavity of the barrel 100 has a concave spherical wall 270, and the washing area and the filtering area are disposed on the spherical wall 270.

[0035] Understandably, the concave spherical wall 270 forms a flow channel, and the smooth surface of the spherical wall 270 with low resistance facilitates the movement of gold powder along the spherical wall 270, accelerates the concentration of gold powder and filtrate in the washing or filtration zone, and improves the washing, drying and filtration efficiency.

[0036] The agitation assembly includes an agitator 110 and a first power component 120 that drives the agitator 110 to rotate. The agitator 110 is located in the washing area and is used to agitate the gold powder inside the tub 100.

[0037] The filtration assembly includes a filtrate chamber 140 and a filter plate 130 disposed between the filtrate chamber 140 and the barrel 100. The filter plate 130 is located in the filtration zone and is used to filter gold powder.

[0038] It is understood that by placing the agitator 110 in the washing zone and the filter plate 130 in the filtration zone, the agitator 110 agitates the gold powder in the washing zone during washing and drying, and the filter plate 130 filters the gold powder during filtration, thus achieving solid-liquid separation. Therefore, washing and filtration are completed within the same tank 100, avoiding the gold powder loss caused by traditional multi-container transfer, and improving production efficiency and greatly shortening production time.

[0039] In some embodiments of this utility model, the filter plate 130 is made of titanium alloy nano-sintered plate.

[0040] In some embodiments of this utility model, the filtrate chamber 140 is rotatably disposed on the barrel 100, and the filtrate chamber 140 rotates to approach the barrel 100 to clamp and fix the filter plate 130.

[0041] Understandably, after the washing liquid is separated, the filtrate chamber 140 can be rotated open to remove the filter plate 130, which makes it easier to remove the gold powder inside the barrel 100, and also makes it easier to clean and replace the filter plate 130, thus improving maintenance efficiency. After the discharge is completed, the filtrate chamber 140 rotates to approach the barrel 100 to clamp and fix the filter plate 130, thus enabling the filter plate 130 to be installed quickly.

[0042] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 The filter assembly also includes a first cylinder 190, one end of which is hinged to the filtrate chamber 140 and the other end of which is hinged to the barrel 100. It can be understood that the first cylinder 190 is used to drive the filtrate chamber 140 to open and close, thereby improving the automation level of the equipment. In addition, the first cylinder 190 is used to quickly install and fix the filtrate chamber 140, thereby improving the opening and closing efficiency of the filtrate chamber 140.

[0043] In some embodiments of this utility model, reference is made to Figure 1 and Figure 4 The filter assembly also includes a clamping cylinder 200, which is installed on the barrel 100. The piston rod of the clamping cylinder 200 is used to press and fix the filtrate chamber 140 to the barrel 100. It can be understood that the clamping cylinder 200 provides sufficient clamping force to prevent the filtrate chamber 140 from loosening and to prevent filtrate leakage caused by displacement or vibration of the filter plate 130. There is no need to use bolts to fix the filtrate chamber 140, thus improving the opening and closing efficiency of the filtrate chamber 140.

[0044] It should be noted that the clamping cylinder 200 can be a rotary clamping cylinder.

[0045] In some embodiments of this utility model, reference is made to Figure 4The barrel 100 has a connecting pipe 150. A first flange 160 is provided at the end of the connecting pipe 150 away from the barrel 100. A second flange 170 is provided in the filtrate chamber 140. A sealing ring 180 is provided on the end face of both the first flange 160 and the second flange 170. The sealing ring 180 is in sealing contact with the filter plate 130.

[0046] Understandably, by using the sealing rings 180 on the end faces of the first flange 160 and the second flange 170 to abut against the filter plate 130, the sealing performance is greatly improved, and leakage of filtrate is avoided.

[0047] In some embodiments of this utility model, a support 250 is also included. The tub 100 is rotatably mounted on the support 250. A second cylinder 260 is hinged between the support 250 and the tub 100. The second cylinder 260 is used to drive the tub 100 to rotate. It can be understood that the second cylinder 260 drives the tub 100 to tilt, which can precisely control the tilt angle of the tub 100 and ensure efficient switching between the washing area and the filtration area.

[0048] In some embodiments of this utility model, reference is made to Figure 4 The filtrate chamber 140 is equipped with a drain pipe 210, which has a first connector and a first solenoid valve 220 located at the first connector. The drain pipe 210 is connected to the vacuum system through the first connector. It can be understood that during the filtration process, the first solenoid valve 220 is opened, and the vacuum system can draw the filtrate from the filtrate chamber 140 under negative pressure, thereby accelerating the flow rate of the filtrate, improving the filtration efficiency, and reducing the residual washing liquid in the tank 100.

[0049] In some embodiments of this utility model, reference is made to Figure 4 The drain pipe 210 has a second connector and a second solenoid valve 230 disposed on the second connector. The drain pipe 210 is connected to the air compression system through the second connector. It can be understood that after filtration is completed, the second solenoid valve 230 is opened, and the air compression system is used to spray air into the filter plate 130 of the filtrate chamber 140 to clear blockage and reduce the blockage of the micropores of the filter plate 130.

[0050] In some embodiments of this utility model, a receiving tray 240 is provided below the barrel 100. The receiving tray 240 is used to receive gold powder, making the collection of gold powder more convenient.

[0051] In some embodiments of this utility model, the barrel 100 is provided with a heater, which is used to heat the gold powder inside the barrel 100.

[0052] By setting up a heater, which can be an electric heater (not shown in the attached diagram), the gold powder can be dried, realizing the integration of washing and drying, and avoiding the loss caused by multiple transfers of gold powder in traditional processes.

[0053] Of course, steam heating can also be used to concentrate and crystallize gold powder, and the corresponding heater can be set according to the process requirements.

[0054] Therefore, the working principle of this embodiment is as follows:

[0055] The tub 100 is rotated at a certain angle, causing it to tilt at a certain angle. The tub 100 is in a first tilted state, allowing the washing liquid and gold powder to flow and gather in the washing area. The first power component 120 drives the agitator 110 to rotate, and the agitator 110 agitates the gold powder inside the tub 100 to wash the gold powder.

[0056] After washing, the tub 100 is rotated in the opposite direction by a certain angle, causing the tub 100 to tilt in the opposite direction by a certain angle. The tub 100 is in a second tilted state, where the washing liquid and gold powder can flow and gather in the filtration zone. In the filtration zone, the filter plate 130 can filter the gold powder, so that the washing liquid and gold powder can achieve solid-liquid separation. Under the action of the vacuum system, the filtrate in the filtrate chamber 140 is extracted.

[0057] Next, the tub 100 rotates to the first tilted state, and the gold powder gathers again in the washing area. The heater heats and dries the gold powder inside the tub 100, and the turner 110 turns the gold powder inside the tub 100 so that the gold powder is fully dried.

[0058] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
