Description

Technical Field

[0001] This invention relates to the field of copper smelting, and in particular to a mineral processing device for recovering copper smelting slag. Background Technology

[0002] Copper smelting is a process that involves crushing, roasting, and smelting copper ore to remove impurities and allow copper to precipitate in its pure or alloyed form. The smelting slag produced after copper smelting still contains some copper; discarding it directly would be a waste of resources. Through mineral processing technologies such as flotation and magnetic separation, this copper can be effectively recovered, improving resource utilization, reducing production costs, and achieving the recycling of copper resources.

[0003] The copper smelting slag recovery process generally involves flotation machines. Their working principle is based on the differences in the physicochemical properties of mineral surfaces. A negative pressure is generated by the rotation of an impeller, drawing in air and mixing it with the slurry. Simultaneously, the slurry and reagents are agitated, causing copper minerals to adhere to the air bubbles, forming a mineralized foam layer. The foam rises by its own overflow and is scraped off by a scraper, resulting in copper concentrate after processing.

[0004] The aforementioned device typically uses scrapers to scrape out foam from both sides, with a drive shaft and a fixed base in the middle for stirring and mixing. After prolonged operation, some foam adheres to the fixed base. As moisture evaporates, this adhered foam gradually forms a solid structure. Once this solid structure forms, it occupies space, hindering the normal flow and collection of subsequent foam, and may also interfere with the stability of the entire mineral processing process, reducing efficiency.

DETAILED DESCRIPTION

[0020] The specific embodiments of the present application are described in detail below, but it should be understood that the protection scope of the present application is not limited by the specific embodiments.

[0021] As Figures 1 to 6 shown, the beneficiation device for copper smelting slag recovery provided by the embodiment of the present application includes a beneficiation tank body 1, and an ore pulp conveying pipe 101 is connected to one side of the beneficiation tank body 1. The main function of the ore pulp conveying pipe 101 is to continuously convey ore pulp into the interior of the beneficiation tank body 1, thereby providing raw materials for subsequent beneficiation operations. A mixing mechanism 5 for mixing bubbles and ore pulp is arranged at the bottom of the interior of the beneficiation tank body 1. A bubble generating device 7 is arranged at the top of the mixing mechanism 5. The internal frame structure of the bubble generating device 7 can refer to the SF type flotation machine or the GF type flotation machine, thereby providing suitable foaming conditions for the mixing of bubbles and ore pulp.

[0022] An upper fixed seat 9 is arranged above the bubble generating device 7. A foam cutting mechanism 10 is arranged on the upper fixed seat 9 in a matched manner. A guide vane 1003 is arranged on the foam cutting mechanism 10. The guide vane 1003 can make a circular motion at the opening of the beneficiation tank body 1. In the process of motion, the guide vane 1003 uses the centrifugal force generated by the circular motion to throw out the ore pulp foam from the beneficiation tank body 1. The range of action of the guide vane 1003 can cover the top of the beneficiation tank body 1, thereby realizing the foam delivery without dead angle, avoiding the problem of long foam residence time of the traditional device, and ensuring that the foam in the beneficiation tank body 1 can be effectively treated. A guide support seat 2 is fixedly arranged around the outer side of the upper edge of the beneficiation tank body 1. A containing cavity for guiding is formed between the guide support seat 2 and the upper edge of the beneficiation tank body 1. The main function of the containing cavity is to receive the ore pulp foam thrown out by the guide vane 1003. A spraying mechanism 3 is arranged on the guide support seat 2. The function of the spraying mechanism 3 is to timely dilute the ore pulp foam and increase the fluidity of the foam, thereby facilitating the subsequent transfer operation.

[0023] As the main innovative structure of the patent, the guide vane 1003 is reversely provided with a curvature for guiding the ore pulp foam along the circumferential motion, which makes the guide vane 1003 as a whole be arranged in an arc shape and be inclined along the radial direction to the rear with the same curvature. As shown in Figure 1 、 Figure 3 and Figure 4 , the front end of the guide vane 1003 is relatively sharp, which can cut the foam during the motion, making it easier to be processed. The rear side of the guide vane 1003 is provided with an arc-shaped accommodating groove for gathering the ore pulp foam, which extends along the guide vane 1003. When the guide vane 1003 makes circumferential motion, the ore pulp foam will enter and gather in the arc-shaped accommodating groove along the guide vane 1003, and then be thrown out of the guide vane 1003 along the arc-shaped accommodating groove under the action of centrifugal force, and impact on the inside of the guide support seat 2 under the action of inertia. At this time, the spray mechanism 3 sprays the dilution liquid, so that the foam is dissolved in the dilution liquid, thereby facilitating the movement of the ore pulp particles for transportation through the pipeline.

[0024] Specifically, the spray mechanism 3 includes a positioning sleeve ring 301 detachably assembled on the guide support seat 2, and a limiting portion 302 is fixedly arranged on the outside of the positioning sleeve ring 301 for cooperation with the upper side of the guide support seat 2. The limiting portion 302 can realize quick positioning of the positioning sleeve ring 301, facilitating installation and disassembly. The positioning sleeve ring 301 is fixedly provided with a water pressure pipe 303, and a plurality of spray heads 304 are arranged at the bottom of the water pressure pipe 303. The dilution liquid contacts the ore pulp foam through the plurality of spray heads 304 along the water pressure pipe 303, and the dilution operation is completed. A collection pipe 201 for discharging the dilution liquid is arranged at the bottom of the guide support seat 2, which facilitates timely discharge of the dilution liquid and ensures normal operation of the entire device.

[0025] In actual operation, impurities may exist in the ore pulp foam. These impurities may be solid suspended blocks formed by mutual combination of suspended matters on the surface of the ore pulp foam, or some relatively large impurities from the environment. These impurities may enter the inside of the guide support seat 2 along with the ore pulp foam, and enter the subsequent pipeline, affecting the subsequent operation. In order to avoid the above situation, a filter plate 305 is fixedly arranged at the inner bottom of the positioning sleeve ring 301, and a plurality of through holes with a hole diameter of about 1 mm are arranged on the filter plate 305. Such a hole diameter design can allow the ground ore pulp particles to enter, and the filter plate 305 is adapted to the shape of the guide support seat 2, thereby achieving the effect of sufficient filtration. The dilution liquid is collected to the collection pipe 201 for discharge after passing through the filter plate 305, and the relatively large impurities are collected above the filter plate 305, thereby completing the impurity removal operation and ensuring that the substances entering the subsequent pipeline are more pure.

[0026] In the traditional air floatation device, the driving motor 4 is generally arranged above the whole device, and is matched with a supporting bracket for maintaining the stability of the whole device. However, this arrangement has some problems, such as that the middle fixing seat is easy to form adhered and deposited blocks, and it is difficult to clean due to the blocking effect of the bracket and the side plate.

[0027] In order to solve this problem, in another embodiment, a motor 4 is fixedly arranged at the bottom of the beneficiation tank body 1 on the basis of the above structure, and a transmission shaft 401 is fixedly arranged at the output end of the motor 4. The transmission shaft 401 transmits kinetic energy to the foam cutting mechanism 10 and the mixing mechanism 5, and realizes the power transmission of the whole device.

[0028] Specifically, the upper fixing seat 9 includes a sleeve 901 fixedly connected with the top of the bubble generating device 7, an upper cover 902 arranged above the sleeve 901, and a connecting component 903 fixedly arranged between the sleeve 901 and the upper cover 902. The connecting component 903 maintains the relative position between the sleeve 901 and the upper cover 902, and ensures the stability of the structure. The transmission shaft 401 penetrates the central axis of the sleeve 901 and is rotationally connected with the upper cover 902. The foam cutting mechanism 10 includes a second inner sleeve wheel 1001 rotationally arranged between the sleeve 901 and the upper cover 902, a guide vane 1003 fixedly arranged outside the second inner sleeve wheel 1001, and a gear structure arranged inside the second inner sleeve wheel 1001. A second transmission wheel 1002 rotationally arranged between the sleeve 901 and the upper cover 902 is in meshing connection with the inside of the second inner sleeve wheel 1001, and a second driving wheel 1004 fixedly arranged on the side surface of the transmission shaft 401 is in meshing connection with the second transmission wheel 1002. In use, the second inner sleeve wheel 1001 can drive the guide vane 1003 to rotate, and the second inner sleeve wheel 1001 is located between the sleeve 901 and the upper cover 902, and the transmission structure is located inside the second inner sleeve wheel 1001.

[0029] The transmission structure of the mixing mechanism 5 is similar to that of the foam cutting mechanism 10, and includes a fixed housing 501 fixedly arranged at the bottom of the beneficiation tank body 1, a transmission shaft 401 penetrating the central axis of the fixed housing 501, an impeller 502 coaxially rotationally arranged on the fixed housing 501, a first inner sleeve wheel 503 coaxially fixedly arranged inside the impeller 502, a gear structure arranged inside the first inner sleeve wheel 503, a first driving wheel 505 fixedly arranged on the side surface of the transmission shaft 401, and a first transmission wheel 504 rotationally arranged inside the housing and in meshing connection with the first driving wheel 505 and the first inner sleeve wheel 503.

[0030] In use, the motor 4 is started to drive the transmission shaft 401 to rotate. The transmission shaft 401 drives the first driving wheel 505 to rotate, the first driving wheel 505 drives the first transmission wheel 504 to rotate, and then drives the first inner sleeve wheel 503 to rotate, and the first inner sleeve wheel 503 drives the impeller 502 to mix and stir the ore pulp, the foaming agent and the collecting agent, so that the bubbles and the ore pulp are fully mixed. At the same time, the transmission shaft 401 drives the second driving wheel 1004 to rotate, the second driving wheel 1004 drives the second transmission wheel 1002 to rotate, and then drives the second inner sleeve wheel 1001 to rotate, and the second inner sleeve wheel 1001 drives the guide vane 1003 to make a circular motion, thereby completing the collection and transportation of the foam.

[0031] As a preferred scheme of the embodiment, the gear transmission ratio of the first inner sleeve wheel 503 and the first transmission wheel 504 is greater than the gear transmission ratio of the second inner sleeve wheel 1001 and the second transmission wheel 1002. Such a design makes the second transmission wheel 1002 able to drive the inside of the second inner sleeve wheel 1001 to produce a greater rotating action. The linear speed of the transmission wheel does not change, but the diameter of the inner sleeve wheel changes, so that the rotating speed of the guide vane 1003 is greater than the rotating speed of the impeller 502, which ensures that the guide vane 1003 can give the foam enough centrifugal force, so that the foam can be smoothly thrown out of the beneficiation tank body 1.

[0032] The bubble generating device 7 needs to be connected to a gas supply pipeline. If the gas supply pipeline is arranged from the side of the beneficiation tank body 1, it will increase the resistance of the ore pulp and affect the flow and mixing effect of the ore pulp. If the gas supply pipeline is arranged from the opening of the beneficiation tank body 1, it will hinder the rotation of the guide vane 1003 and affect the collection and transportation of the foam. In order to solve this problem, the gas connection pipeline 6 can be arranged on the inside of the upper cover 902 and the sleeve shell 901. Since the upper cover 902 and the sleeve shell 901 are stationary, the stability of the gas connection pipeline 6 can be ensured, and the effect of other functional modules will not be affected. The output end of the gas connection pipeline 6 is in communication with the input end of the bubble generating device 7, and the interface of the gas connection pipeline 6 is arranged on the top of the upper cover 902, so as to meet the gas supply demand of the bubble generating device 7, and will not have adverse effects on other parts of the device.

[0033] Working principle: when the copper smelting slag recovery beneficiation device works, the motor 4 is started to drive the transmission shaft 401 to rotate. The transmission shaft 401 drives the first driving wheel 505 to rotate, the first driving wheel 505 drives the first transmission wheel 504 to rotate, and then drives the first inner sleeve wheel 503 to rotate, and the first inner sleeve wheel 503 drives the impeller 502 to mix and stir the ore pulp, the foaming agent and the collecting agent in the beneficiation tank body 1, so that the bubbles and the ore pulp are fully mixed, and suitable conditions are provided for subsequent beneficiation operation.

[0034] At the same time, the transmission shaft 401 drives the second driving wheel 1004 to rotate, the second driving wheel 1004 drives the second transmission wheel 1002 to rotate, and then drives the second inner sleeve wheel 1001 to rotate, and the second inner sleeve wheel 1001 drives the guide vane 1003 to make a circular motion. The front end of the guide vane 1003 is sharp, and in the movement process, the foam is cut, so that it is easier to handle. The guide vane 1003 is reversely provided with a curvature along the circular motion, and the whole is arc-shaped and inclined along the radial direction backward with the same curvature, and the rear side is provided with an arc-shaped accommodating groove. The ore pulp foam enters the arc-shaped accommodating groove along the guide vane 1003 and is gathered in the arc-shaped accommodating groove, and is thrown out of the guide vane 1003 under the action of the centrifugal force, and is impacted on the inside of the guide bearing seat 2 under the action of inertia.

[0035] At this time, the diluent in the water pressure pipe 303 is sprayed through the plurality of spray heads 304, contacts the ore pulp foam, and makes the foam dissolve in the diluent, so that the ore pulp particles are driven to move by the pipeline to realize transportation. The diluent is collected to the collecting pipe 201 after passing through the filter plate 305, and the impurities with large volume are collected above the filter plate 305, the impurity removal operation is completed, and the substances entering the subsequent pipeline are ensured to be more pure.

[0036] The above only discloses several specific embodiments of the present application, but the embodiments of the present application are not limited to this, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present application.
