Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lead-zinc ore flotation recovery devices, specifically to a high-efficiency low-grade lead-zinc ore flotation recovery device. BACKGROUND

[0002] The high-efficiency low-grade lead-zinc ore flotation recovery device is a device for improving the utilization rate of low-grade lead-zinc ore resources. It can effectively enrich and separate lead-zinc minerals by precisely controlling the flotation process, such as controlling the addition of reagents and stirring intensity, to achieve efficient recovery, with the advantages of energy saving, high recovery rate, etc., which is of great significance to mineral development.

[0003] For example, the publication number: CN217511665U discloses a high-efficiency reagent mixing device for low-grade lead-zinc ore separation, which includes a shell, a bottom of the shell surface is sleeved with a base welded, a lifting assembly is installed on the top of the base, a cover plate is placed on the top of the shell, a driving assembly is installed on the surface of the lifting assembly, a stirring assembly one and a stirring assembly two are installed on the surface of the cover plate, the lifting assembly includes an electric telescopic rod, the bottom of the electric telescopic rod is fixedly connected with the top of the base, the utility model solves the problem that the existing reagent mixing device for low-grade lead-zinc ore separation usually has multiple stirring paddles in a mixing tank, and the mixing effect of such a one-way mixing machine is not ideal, and the tank body and the sealing cover are connected through bolts and nuts, which is not convenient for cleaning when it needs to be cleaned.

[0004] However, the device in this application directly discharges tailings from the discharge port when discharging slag, which cannot control the particle size of the discharged material, and may cause the particle composition of the slurry in the flotation device to change constantly, such as excessive loss of fine particles or excessive retention of large particles, resulting in unstable properties of the slurry such as concentration and viscosity. These properties have important influence on the effect of flotation reagents, the combination of bubbles and mineral particles, etc., which makes the flotation process difficult to be stable and efficient, and reduces the quality of the flotation product.

[0005] APPLICATION CONTENT

[0006] The purpose of the present application is to solve the problem of directly discharging tailings from the discharge port when discharging slag, which cannot control the particle size of the discharged material, and to provide a high-efficiency low-grade lead-zinc ore flotation recovery device.

[0007] The technical scheme adopted by the application is as follows: a high-efficiency low-grade lead-zinc ore flotation recovery device, comprising a pump machine, one end of the pump machine is provided with a residue discharge pipeline, the lower end of the residue discharge pipeline is fixedly connected with a separation pipeline A, the inner side of the residue discharge pipeline is provided with a filter screen A, the lower end of the residue discharge pipeline is fixedly connected with a separation pipeline B, the inner side of the residue discharge pipeline is provided with a filter screen B, the lower end of the residue discharge pipeline is fixedly connected with a separation pipeline C, and the inner side of the residue discharge pipeline is provided with a filter screen C.

[0008] By adopting the above technical scheme, different size filter screens are arranged at the residue discharge port of the high-efficiency low-grade lead-zinc ore flotation recovery device. In the process of recovering the ore residue, the larger ore residue is first blocked by the filter screen A and then discharged through the separation pipeline A; the finer ore residue is blocked by the filter screen B and then discharged through the separation pipeline B; the finer ore residue is blocked by the filter screen C and then discharged through the separation pipeline C; and the finest ore residue is discharged through the pipeline port of the residue discharge pipeline. Different size filter screens can screen different size mineral particles in the tailings. For example, the finer filter screen can intercept the fine useful mineral particles that have not been completely separated by flotation, so that they are returned to the flotation process to continue to participate in flotation, and the real waste residue passes through, which helps to improve the purity of the waste residue in the tailings, avoids the waste of useful minerals, and maximizes the recovery of lead, zinc and other mineral resources. After the tailings are filtered by multiple layers of filter screens of different sizes, the impurities such as large particles and fine particles contained in the tailings are well controlled, and subsequent processing of the tailings such as tailings storage, reprocessing and utilization is relatively simple. For example, storage is less likely to cause compaction and seepage due to uneven particles. The operator can more accurately understand the dissociation and separation state of the mineral particles in the flotation process according to the substances intercepted by the filter screens of different sizes, and then adjust the flotation process parameters such as reagent addition amount and stirring intensity, so that the entire flotation recovery process operates more accurately and efficiently.

[0009] In a preferred embodiment, one end of the pump machine is provided with a reaction kettle.

[0010] By adopting the above technical scheme, the reaction kettle provides a relatively closed and specific space environment for the lead-zinc ore flotation process, can accommodate the ore slurry and allow it to fully perform various flotation-related processes such as chemical reactions and physical mixing inside, ensuring that the flotation operation is orderly and stable, and is the key core place of the entire flotation recovery, bearing the important mission of realizing mineral separation and enrichment.

[0011] In a preferred embodiment, the upper end of the reaction kettle is provided with a reaction kettle cover plate, and the outer surface of the reaction kettle is provided with a plurality of reaction kettle cover plate clamping arms.

[0012] By adopting the technical scheme, the cover plate of the reaction kettle covers the top of the reaction kettle, plays a role in sealing the reaction kettle, avoids impurities from the outside mixing into the ore pulp being floated, and also prevents the ore pulp from splashing out during stirring and flotation, maintains the stable environment in the reaction kettle, and is beneficial to the normal operation of the flotation work. The cover plate clamping arm is mainly used for firmly fixing the cover plate of the reaction kettle, ensuring that the cover plate is tightly attached to the reaction kettle, ensuring the sealing effect, so that the cover plate can be stably fixed in place and maintain a good working state regardless of the vibration or shaking caused by stirring, foaming and other operations during the operation of the device.

[0013] In a preferred embodiment, the upper surface of the reaction kettle cover plate is fixedly connected with a feed inlet.

[0014] By adopting the technical scheme, the feed inlet is a channel for conveying the pretreated low-grade lead-zinc ore pulp into the reaction kettle, and is a key hub connecting the external ore source and the flotation core area, which can ensure that the ore pulp enters the reaction kettle continuously according to the demand, thereby starting the subsequent flotation process. The position and size of the feed inlet have a significant impact on the smoothness of the feed.

[0015] In a preferred embodiment, the lower end of the reaction kettle is fixedly connected with a bottom plate.

[0016] By adopting the technical scheme, the bottom plate serves as the bottom support structure of the entire device, bearing the weight of the reaction kettle, the stirring motor and many other components, and must have sufficient strength and stability to ensure that the device can be placed stably on the ground or operation platform, and lay a solid foundation for the safe and reliable operation of the entire flotation recovery device.

[0017] In a preferred embodiment, the upper surface of the bottom plate is fixedly connected with a control panel.

[0018] By adopting the technical scheme, the control panel is an important interface for the operator to interact with the flotation recovery device, through which the speed of the stirring motor, the amount of flotation reagent added and many other key parameters can be accurately controlled, the automatic control of the entire flotation process is realized, and the flotation operation can be efficiently and accurately performed according to the actual situation.

[0019] In a preferred embodiment, the upper surface of the bottom plate is fixedly connected with a stirring motor fixing frame, and the lower surface of the stirring motor fixing frame is provided with a stirring motor.

[0020] The stirring motor fixing frame is used to stably mount the stirring motor, so that the stirring motor can keep a fixed position and posture during operation, and displacement and shaking caused by vibration of the motor itself or reaction of stirring can be avoided, thereby providing reliable support conditions for stable operation of the stirring motor. The stirring motor provides a power source for rotation of the stirring blade, drives the stirring blade to rotate by outputting appropriate torque, and promotes the ore slurry and the flotation reagent in the reaction kettle to be fully mixed and stirred uniformly, so that the mineral particles can better contact the reagent and react, and the stirring motor is an important power component for ensuring the flotation effect.

[0021] In a preferred embodiment, the lower end of the stirring motor is rotationally connected with the stirring blade through the rotating track.

[0022] The stirring blade continuously rotates in the reaction kettle under the drive of the stirring motor, fully stirs the ore slurry through the unique shape and rotation action, breaks the original particle agglomeration state in the ore slurry, and makes the mineral particles, the flotation reagent, and the generated bubbles uniformly distributed, thereby effectively improving the efficiency and quality of flotation, and the stirring blade is an indispensable key stirring component in the flotation process.

[0023] In summary, due to the adoption of the above technical solutions, the application has the following beneficial effects:

[0024] In the application, different sizes of filter screen structures are arranged at the slag discharge port of the high-efficiency low-grade lead-zinc ore flotation recovery device. During the recovery of the ore slag, the larger ore slag is first blocked by filter screen A and then discharged through separation pipeline A; the finer ore slag is blocked by filter screen B and then discharged through separation pipeline B; the finer ore slag is blocked by filter screen C and then discharged through separation pipeline C; and the finest ore slag is discharged through the pipeline port of the slag discharge pipeline. The different sizes of filter screens can screen the mineral particles of different sizes in the tailings. For example, the finer filter screen can intercept the fine useful mineral particles that have not been completely separated by flotation, so that the useful mineral particles are returned to the flotation process for continuous flotation, and the real waste slag is discharged, which helps to improve the purity of the waste slag in the tailings, avoids waste of useful mineral resources, and maximizes recovery of lead, zinc and other mineral resources. After the tailings are filtered through multiple layers of filter screens of different sizes, the impurities such as large particles and fine particles contained in the tailings are well controlled, and subsequent processing of the tailings such as tailings storage, reprocessing and utilization is relatively simple. For example, storage is less likely to cause compaction and seepage due to uneven particles. The operator can more accurately understand the dissociation and separation state of the mineral particles in the flotation process according to the substances intercepted by the filter screens of different sizes, and then adjust the flotation process parameters such as reagent addition amount and stirring intensity, so that the entire flotation recovery process operates more accurately and efficiently.
