[0027] A gold powder washing and drying machine according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] Reference Figure 1 The present invention aims to provide an embodiment of a gold powder washing and drying machine.

[0029] A gold powder washing and drying machine according to an embodiment of the present invention includes a barrel 100 and a turning assembly. The barrel 100 contains gold powder, and the inner cavity of the barrel 100 has a concave spherical wall 110. The turning assembly includes a turner 120 and a first power member 130 for driving the turner 120 to rotate. The turner 120 is located inside the barrel 100 and is used to turn the gold powder inside the barrel 100.

[0030] Among them, reference Figure 2 and Figure 3 The flipper 120 has a central shaft 140 and a plurality of spiral strips 150 distributed circumferentially along the central shaft 140. The spiral strips 150 are in contact with the spherical wall 110, and one end of the spiral strip 150 is connected to the central shaft 140, while the other end of the spiral strip 150 extends spirally upward along the spherical wall 110.

[0031] It is understood that by fitting the concave spherical wall 110 with the spiral strip 150, the first power component 130 drives the central shaft 140 to rotate, causing the spiral strip 150 to slide along the surface of the spherical wall 110. This allows the gold powder on the bottom wall inside the barrel 100 to be fully turned up. Furthermore, by extending the spiral strip 150 spirally upward along the spherical wall 110, the rotation of the spiral strip 150 generates a spiral upward fluid force, causing the gold powder on the bottom wall of the barrel 100 to flow upward, promoting thorough mixing of the gold powder with the washing liquid and improving washing uniformity. In addition, the concave spherical wall 110 is designed to guide the gold powder to gather towards the center, avoiding poor flowability of the gold powder at the inner edge of the barrel 100. Thus, under the action of the concave spherical wall 110 and the spiral strip 150, the gold powder can be rapidly turned up and down, improving material circulation efficiency and the washing efficiency of the gold powder.

[0032] In some embodiments of this utility model, the flipper 120 also has a plurality of connecting rods 160, which are distributed along the axial direction of the central axis 140, and the connecting rods 160 connect two spiral strips 150.

[0033] Understandably, the connecting rod 160 horizontally fixes the spiral strip 150 to enhance the overall structural strength of the turner and prevent the spiral strip 150 from deforming or breaking during turning.

[0034] In some embodiments of this utility model, the spiral strip 150 is made of polytetrafluoroethylene sheet.

[0035] Understandably, polytetrafluoroethylene (PTFE) is highly corrosion-resistant, which helps prevent washing liquids (such as acidic solutions) from corroding the agitator and extends its service life.

[0036] In addition, the low coefficient of friction of PTFE material reduces the adhesion of gold powder to the slats, reduces gold powder loss, and improves the recovery rate. It also reduces the friction between the spiral slats 150 and the barrel 100, improving the durability of the spiral slats 150.

[0037] In some embodiments of this utility model, reference is made to Figure 2 The barrel 100 is equipped with a filter 170, which is located on the spherical wall 110. The filter 170 and the agitator 120 are arranged adjacent to each other. The filter 170 is used to filter gold powder inside the barrel 100.

[0038] It is understandable that by arranging the filter 170 and the agitator 120 adjacent to each other, the positions of the agitator 120 and the filter 170 are avoided from overlapping. During the process of the agitator 120 agitating the gold powder, the gold powder will not rub against the filter 170, thus reducing the damage to the filter 170.

[0039] In addition, during the filtration process, the barrel 100 can be tilted at a certain angle so that the gold powder and washing liquid move toward the filter 170. Furthermore, the filter 170 is located on the spherical wall 110. The concave spherical wall 110 can quickly gather the gold powder and washing liquid onto the filter 170, which is beneficial for quickly filtering out the gold powder and facilitating the subsequent drying process of the gold powder.

[0040] It should be noted that the filter 170 has a filtrate chamber, a filter plate disposed in the filtrate chamber, and a switch valve disposed in the filtrate chamber. The filter plate can filter gold powder, the filtrate chamber can receive the filtrate, and the switch valve can discharge the gold powder to the outside.

[0041] In some embodiments of this utility model, reference is made to Figure 1It also includes a flipping assembly, which includes a bracket 180 rotatably connected to the outer wall of the barrel 100, a second power component 190 that drives the barrel 100 to flip up and down, a filter 170 and a flipper 120 arranged along the flipping direction of the barrel 100.

[0042] Understandably, after the agitator 120 agitates and washes the gold powder, the second power component 190 drives the tank 100 to rotate on the support 180. The angle of rotation of the tank 100 causes the gold powder and washing liquid to move towards the filter 170. Thus, there is no need to manually agitate the tank 100, which improves the automation level of the equipment. Furthermore, it improves the rotation accuracy of the tank 100, which is beneficial for quickly separating the gold powder and washing liquid.

[0043] In some embodiments of this utility model, the second power component 190 is a cylinder, one end of which is hinged to the bracket 180, and the other end of which is hinged to the barrel body 100.

[0044] Understandably, the cylinder can precisely control the barrel to rotate 100 degrees. Depending on the design requirements, the rotation angle can be 30°, 45°, 60° and 90°, etc., to adapt to different process needs.

[0045] In some embodiments of this utility model, two symmetrically arranged rotating shafts 200 are provided on the outer side wall of the barrel 100, and the bracket 180 has bearing seats 210 that match the rotating shafts 200. It is understood that the symmetrical rotating shafts 200 and bearing seats 210 ensure a smooth flipping process and reduce the impact of barrel 100 vibration on the internal structure.

[0046] In some embodiments of this utility model, the outer peripheral wall of the barrel 100 is a cylindrical structure, the spherical wall 110 is a hemispherical structure, and the central axis 140 extends from the outer periphery of the barrel 100 toward the interior of the barrel 100 near the spherical wall 110, and the axis of the central axis 140 intersects with the axis of the barrel 100.

[0047] Understandably, the intersection of the axis of the central shaft 140 and the axis of the barrel 100 optimizes the area occupied by the filter 170 and the agitator 120 on the spherical wall 110, making the ratio of the area occupied by the filter 170 and the agitator 120 on the spherical wall 110 more reasonable. In addition, the first power component 130 will not occupy the opening 220 position at the top of the barrel 100, which facilitates the cleaning and maintenance of the inside of the barrel 100 after gold powder processing.

[0048] In some embodiments of this utility model, reference is made to Figure 1The top of the barrel 100 has an opening 220 and a cover 230 that matches the opening 220. The cover 230 is used to open or cover the opening 220. It is understood that the openable and closable cover 230 facilitates feeding, maintenance and cleaning, while preventing washing liquid from splashing or harmful gases such as acid gas from escaping. Of course, acid gas can be discharged to a designated location through the exhaust pipe of the cover 230.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] After the gold powder is filtered, it undergoes a drying process. The barrel can be rotated at a certain angle, and the gold powder flows to the agitator. The spiral strips 150 can fully agitate the gold powder on the bottom wall inside the barrel 100, so that the gold powder is heated evenly, which is conducive to the thorough drying of the gold powder and avoids the situation where the gold powder on the bottom wall inside the barrel 100 is not dried.

[0053] 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.

[0054] 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.
