Description

Technical Field

[0001] The invention belongs to the technical field of iron tailings processing, and in particular relates to a powder ore dry separator with a recovery structure and a construction method thereof. Background Art

[0002] In the mining industry, dry powder ore separators are an important type of equipment, which are mainly used to separate valuable minerals from ores. Traditional dry powder ore separators often have some shortcomings during operation, such as low separation efficiency, serious waste of resources, and environmental pollution. In response to these problems, researchers and engineers have been seeking ways to improve and innovate.

[0003] The traditional dry-throw tailings treatment method uses crushing and grading to convert tailings into a variety of products. However, this method ignores the reuse value of recoverable magnetic iron in building material stone powder during the treatment process. Building material stone powder contains a high proportion of magnetic iron, which has significant reuse value. Due to the lack of effective recycling and utilization measures, the precious magnetic iron resources have not been fully utilized, resulting in a waste of resources.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a powder ore dry separator with a recovery structure and a construction method thereof.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A powder ore dry separator with a recovery structure and a construction method thereof, comprising: a dry magnetic separator, a ball mill is arranged on one side of the dry magnetic separator, a connecting pipe is installed between the dry magnetic separator and the ball mill, a high-efficiency magnetic separator is arranged on one side of the ball mill, a coarse separation recovery box is fixedly connected to the lower side of the high-efficiency magnetic separator, a discharge pipe is fixedly connected to one side of the high-efficiency magnetic separator, a fine separation recovery box is fixedly connected to one side of the discharge pipe, a filtering mechanism is arranged inside the fine separation recovery box, and a driving mechanism matched with the filtering mechanism is arranged inside the fine separation recovery box.

[0008] By setting up a high-efficiency magnetic separator, the materials processed by the ball mill are magnetically classified under the action of the high-efficiency magnetic separator, so that the materials are divided into coarse selected materials and fine selected materials. The fine selected materials are screened under the action of the filtering mechanism, so that the fine selected materials that meet the requirements are collected in the fine material collection box, and the materials that cannot be screened flow into the coarse material collection box, thereby improving the material recovery effect, reducing the amount of tailings, and improving resource utilization.

[0009] Preferably, both ends of the connecting pipe are respectively connected to the dry magnetic separator and the ball mill, and the lower side of the high-efficiency magnetic separator is connected to the roughing recovery box.

[0010] Preferably, the filtering mechanism includes mounting blocks fixedly connected to both sides of the inner wall of the fine selection recovery box, a filter plate is elastically fitted on the upper side of the multiple mounting blocks, two vibration mechanisms are installed on the lower side of the filter plate, and a bent pipe is fixedly connected to one side of the fine selection recovery box.

[0011] Preferably, the filter plate is slidably fitted on the inner wall of the fine selection recovery box, one end of the fine selection recovery box is matched with one end of the bent pipe, and the other end of the bent pipe is fixedly connected to one side of the rough selection recovery box.

[0012] Preferably, the driving mechanism includes a rotating shaft rotatably engaged with the inner wall of the fine selection recovery box, two gears are installed on the rotating shaft, the lower end of the filter plate is fixedly connected to two racks, and one end of the rotating shaft is fixedly connected to a turntable.

[0013] Preferably, the gear is meshed with the rack, and one end of the rotating shaft extends to one side of the fine selection recovery box.

[0014] Preferably, a mounting ring block is fixedly connected to the rotating shaft, a rubber ball is installed on the mounting ring block, a limiting support block is fixedly connected to one side of the inner wall of the fine selection recovery box, the rubber ball cooperates with the filter plate, and the limiting support block cooperates with the filter plate.

[0015] Preferably, a fine material collection box is slidably matched on one side of the fine selection recovery box, and a coarse material collection box is slidably matched on one side of the coarse selection recovery box.

[0016] A construction method of a powder ore dry separator with a recovery structure, comprising the powder ore dry separator with a recovery structure as described above, and the specific operation is as follows:

[0017] When processing iron tailings powder ore, dry magnetic separation is performed on the iron tailings powder ore under the action of a dry magnetic separator to complete the pre-selection of the material. The pre-selected material is transported to the ball mill through a connecting pipe. The dry throwing stage can throw as much as possible, which not only increases the efficiency of tailings building materials, but also reduces the amount of tailings entering the grinding and selection system, with a significant cost reduction effect. The material processed by the ball mill is transported to a high-efficiency magnetic separator, and the material is efficiently magnetically separated by the high-efficiency magnetic separator, so that the material that meets the requirements is transported to the fine selection recovery box, and the rough selection material enters the rough selection recovery box for recycling;

[0018] The material enters the fine selection recovery box, and is screened by the filter plate, so that the material with the required particle size is screened into the fine material collection box. Under the action of the vibration mechanism, the filter plate vibrates to improve the screening effect of the material on the filter plate. The filter plate moves up and down in the fine selection recovery box, and drives the rotating shaft to rotate under the transmission of the gear and rack, so that the rubber ball arranged on the rotating shaft intermittently knocks the lower side of the filter plate, further improving the vibration filtering effect of the filter plate. After the material on the filter plate is screened, the staff rotates the turntable to drive the rotating shaft to rotate. Under the transmission of the gear and rack, the filter plate slides downward in the fine selection recovery box, and one end of the filter plate contacts the limit support block. As the filter plate continues to descend, the filter plate tilts, so that the unscreened material on the filter plate is transported to the coarse material collection box through the curved pipe, avoiding the mixing of coarse and fine materials and ensuring the accuracy of material recovery.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below at the same time:

[0020] By setting up a high-efficiency magnetic separator, the materials processed by the ball mill are magnetically classified under the action of the high-efficiency magnetic separator, so that the materials are divided into coarse selected materials and fine selected materials. The fine selected materials are screened under the action of the filtering mechanism, so that the fine selected materials that meet the requirements are collected in the fine material collection box, and the materials that cannot be screened flow into the coarse material collection box, thereby improving the material recovery effect, reducing the amount of tailings, and improving resource utilization.
