Description

Technical Field

[0001] This utility model relates to the field of gold smelting technology, and in particular to a concentrate pretreatment and screening device for gold smelting. Background Technology

[0002] Metal smelting is the process of changing metals from a combined state to a free state. Ores with low-grade valuable metals are mechanically enriched through processes such as radioactive separation, gravity beneficiation, and flotation to obtain ores with a certain yield and higher-grade valuable metals. This portion of the ores enriched with valuable metals is called concentrate.

[0003] In the process of gold smelting concentrate screening, a single screen cannot cope with the complex particle size distribution of the concentrate, and the screen is prone to clogging and difficult to clean. In addition, the large amount of dust generated will cause serious pollution to the surrounding atmospheric environment if it is not effectively treated. Therefore, we propose a gold smelting concentrate pretreatment screening device. Utility Model Content

[0004] This utility model is proposed to address the shortcomings of existing technologies by providing a gold smelting concentrate pretreatment screening device. This gold smelting concentrate pretreatment screening device solves the problems that a single screen cannot cope with complex concentrate particle size distributions, and that the screen is prone to clogging and difficult to clean, and that the large amount of dust generated will cause serious pollution to the surrounding atmospheric environment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown, a gold smelting concentrate pretreatment screening device places the screening box 1 on a stable working surface to ensure its stability. A controller 2 is installed on the right side of the screening box 1, and the controller 2 can control the entire device through a wiring connection.

[0022] A feed hopper 3 is installed on the left side of the screening box 1. The feed hopper 3 is connected to the inside of the screening box 1 so that the concentrate can enter the screening box 1 smoothly.

[0023] A door 4 is installed on the front side of the screening box 1. The door 4 can be connected by hinges for easy opening and closing, and is used for inspection and maintenance of the interior of the screening box 1.

[0024] A soft rubber plate 5 is installed on the upper side of the screening box 1. The soft rubber plate 5 can play a certain role in sealing and buffering.

[0025] The coarse screen 7 and the fine screen 8 are respectively installed in the two mounting slots 6, and side plates 9 are installed on both sides of the coarse screen 7 and the fine screen 8.

[0026] Several springs 10 are installed on one side of the side plate 9, and one end of the spring 10 is made to abut against one side of the screening box 1.

[0027] Install a base plate 12 on one side of the screening box 1, and fix the motor 13 on the upper side of the base plate 12. Install the connecting rod 14 on the shaft end of the motor 13, and install a protrusion 15 on the outer side of the connecting rod 14.

[0028] An air collecting hood 16 is installed on the upper side of the soft rubber plate 5, and a conduit 17 is connected to the upper side of the air collecting hood 16. The other end of the conduit 17 is connected to the water tank 18.

[0029] A top cover 19 is installed on the upper side of the water tank 18, and a water injection pipe 20 is installed on the upper side of the top cover 19 to facilitate the filling of water into the water tank 18. A dustproof and breathable plate 21 is installed on one side of the water tank 18.

[0030] A bracket 22 is installed on the upper side of the screening box 1, a positioning plate 23 is installed on one side of the bracket 22, a connecting rod 14 is sleeved on one side of the positioning plate 23, and a gear 28 is installed on the top of the connecting rod 14.

[0031] Gear 28 and gear 24 are connected by transmission component 27. A guide rod 25 is installed on one side of gear 24, and a suction impeller 26 is installed at one end of the guide rod 25, with the suction impeller 26 located inside the air collection hood 16.

[0032] In this embodiment, gold smelting concentrate enters the screening box 1 through the feed hopper 3. The operator can set the screening parameters on the controller 2 according to actual needs, thereby precisely controlling the entire screening process.

[0033] The motor 13 is started, and the motor 13 drives the connecting rod 14 at the shaft end to perform a circular motion. During the rotation, the protrusion 15 on the outer side of the connecting rod 14 periodically contacts and pushes the pusher 11 on the side plate 9. Since the side plate 9 is fixed on both sides of the coarse screen 7 and the fine screen 8, and the spring 10 on one side of the side plate 9 abuts against the screening box 1, the side plate 9 drives the coarse screen 7 and the fine screen 8 to reciprocate under the push of the protrusion 15. Under the action of vibration, coarse particles of concentrate are intercepted on the coarse screen 7, while fine particles pass through the coarse screen 7 and are further screened on the fine screen 8. Even smaller qualified concentrate particles pass through the fine screen 8 to complete the screening, thereby achieving the separation of concentrates of different particle sizes.

[0034] When motor 13 drives connecting rod 14 to rotate, gear 28 at the top of connecting rod 14 rotates synchronously. Gear 28 meshes with gear 24 through transmission component 27, driving gear 24 to rotate, which in turn causes guide rod 25 connected to one side of gear 24 to drive suction impeller 26 to rotate at high speed inside the air collection hood 16. The rotation of suction impeller 26 generates strong suction, drawing dust generated during the screening process into the air collection hood 16. The dust enters water tank 18 through duct 17. In water tank 18, the dust comes into contact with water and is absorbed and filtered by the water. The purified air is then discharged through dustproof and breathable plate 21 on one side of water tank 18, effectively preventing dust pollution to the environment.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
