[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following is in conjunction with the appendix Figures 1-4 The embodiments of this utility model will be described in further detail.

[0031] Example 1

[0032] Please see Figures 1-4 This embodiment provides a technical solution: a filtration device for wet gold smelting, comprising: a processing box 1, a filtration assembly 2, a cleaning mechanism 3, and an absorption mechanism 4;

[0033] The main body of the filtration device includes a processing box 1 and a filter assembly 2. The top and bottom of the processing box 1 are respectively provided with pipes for feeding and discharging. The filter assembly 2 is located inside the processing box 1. The filter assembly 2 consists of a frame and a filter screen welded inside. A bearing is provided in the middle of the frame of the filter assembly 2. The above is the prior art and will not be described in detail below.

[0034] Cleaning mechanism 3 is located inside the feed pipe of processing box 1. Cleaning mechanism 3 includes a first connecting pipe 301 whose bottom end is fixed in the bearing of filter assembly 2, a groove is formed at the top end of the first connecting pipe 301, and a through hole is formed on the inner wall of the groove of the first connecting pipe 301, a drive motor 302 fixed on the top outer wall of processing box 1, a first pulley 303 set outside the first connecting pipe 301, and a second pulley 304 fixed on the output end of drive motor 302. The two ends are respectively sleeved on the first connecting pipe 301. A large belt 305 on a pulley 303 and a second pulley 304 are welded to a third connecting pipe 306 on the outer wall of the through hole of the first connecting pipe 301. The interior of the third connecting pipe 306 is connected to the interior of the first connecting pipe 301. A hole is opened on one side of the bottom of the first connecting pipe 301. A cleaning brush 307 is set on the other side of the bottom of the first connecting pipe 301. The bottom end of the cleaning brush 307 is attached to the upper surface of the filter screen of the filter assembly 2. The cleaning brush 307 is made of hard plastic bristles.

[0035] The absorption mechanism 4 is located inside the groove of the first connecting pipe 301.

[0036] The ore mixed with the chemical reagent is conveyed together from the feed pipe of the processing box 1. At this time, the ore mixed with the chemical reagent is separated by the filter screen of the filter component 2. The ore stays above the filter screen of the filter component 2, while the chemical reagent containing gold stays inside the processing box 1 below the filter screen of the filter component 2. Subsequently, the chemical reagent containing gold can be discharged through the discharge pipe at the bottom of the processing box 1.

[0037] When it is necessary to clean and remove the ore from the mesh of the filter assembly 2, the drive motor 302 is started. Since the first pulley 303 and the second pulley 304 are connected by a large belt 305, the drive motor 302 drives the second pulley 304 on the output end to rotate. At the same time, it drives the first connecting pipe 301 inside the first pulley 303 to rotate stably in the bearing within the frame of the filter assembly 2. While the first connecting pipe 301 is rotating, it drives the cleaning brush 307 at the bottom of the third connecting pipe 306 connected to the outside. Through rotation, the ore in the mesh of the filter assembly 2 is displaced, thereby separating and falling out from the mesh of the filter assembly 2.

[0038] Example 2

[0039] Please see Figures 1-4 This embodiment provides a technical solution: a filtration device for wet gold smelting, comprising: a fourth connecting pipe 401, a vacuum cleaner 402, a fifth connecting pipe 403, and a rubber sealing ring 404;

[0040] The absorption mechanism 4 includes a fourth connecting pipe 401 welded to the outer wall of the hole in the third connecting pipe 306. The fourth connecting pipe 401 is L-shaped. A vacuum cleaner 402 is fixed to the top outer wall of the processing box 1. One end of the vacuum cleaner 402 is connected to the air inlet of the vacuum cleaner 402. The other end of the fifth connecting pipe 403 is inserted into the groove of the first connecting pipe 301. The fifth connecting pipe 403 is made of metal pipe.

[0041] A rubber sealing ring 404 is fitted on the outer wall of the fifth connecting pipe 403, and the rubber sealing ring 404 is located between the gap between the first connecting pipe 301 and the fifth connecting pipe 403.

[0042] When it is necessary to clean the tiny minerals separated from the filter screen of filter assembly 2, start the vacuum cleaner 402. The vacuum cleaner 402 is inserted into the first connecting pipe 301 through the fifth connecting pipe 403, and the rubber sealing ring 404 seals the gaps, ensuring that the first connecting pipe 301 will not drive the fifth connecting pipe 403 to rotate synchronously during rotation. At this time, the vacuum cleaner 402 transmits suction power to the inside of the third connecting pipe 306, thereby absorbing the tiny minerals cleaned by the cleaning brush 307 through the fourth connecting pipe 401 and storing them inside the vacuum cleaner 402.

[0043] The implementation principle of the filtration device for hydrometallurgical gold refining according to this utility model is as follows:

[0044] First, the ore mixed with the chemical reagent is conveyed together from the feed pipe of the processing box 1. At this time, the ore mixed with the chemical reagent is separated by the filter screen of the filter component 2. The ore stays above the filter screen of the filter component 2, while the chemical reagent containing gold stays inside the processing box 1 below the filter screen of the filter component 2. Subsequently, the chemical reagent containing gold can be discharged through the discharge pipe at the bottom of the processing box 1.

[0045] Secondly, when it is necessary to clean and remove the ore from the mesh of the filter assembly 2, the drive motor 302 is started. Since the first pulley 303 and the second pulley 304 are connected by a large belt 305, the drive motor 302 drives the second pulley 304 on the output end to rotate, thereby simultaneously driving the first connecting pipe 301 inside the first pulley 303 to rotate stably in the bearing within the frame of the filter assembly 2. At the same time as the first connecting pipe 301 rotates, it drives the cleaning brush 307 at the bottom of the third connecting pipe 306 connected to the outside. Through rotation, the ore in the mesh of the filter assembly 2 is displaced, thereby separating and falling out from the mesh of the filter assembly 2.

[0046] Finally, when it is necessary to clean the tiny minerals separated from the filter screen of filter assembly 2, start the vacuum cleaner 402. The vacuum cleaner 402 is inserted into the first connecting pipe 301 through the fifth connecting pipe 403, and the gap is sealed by the rubber sealing ring 404, so that the first connecting pipe 301 will not drive the fifth connecting pipe 403 to rotate synchronously during rotation. At this time, the vacuum cleaner 402 transmits suction to the inside of the third connecting pipe 306, and then absorbs the tiny minerals cleaned by the cleaning brush 307 through the fourth connecting pipe 401 and stores them inside the vacuum cleaner 402.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
