[0002] In the process of metal mine mining in China, blasting operations are mostly used. During the blasting process, plastic detonator tubes are generally selected for detonation. After blasting, the ore contains detonator tubes that cannot be recovered. They are transported to the concentrator together and enter the crushing, grinding and ore dressing process. The detonator tubes are ground into flocculent plastic objects by steel balls and ore in the mill. The flocculent objects are light in weight and float on the upper surface of the pulp and enter each stage of the separation process together with the useful minerals. The pulp in each stage of the separation process needs to be transported by a delivery pump. During the transportation process, the flocculent plastic objects will block the impeller of the delivery pump and the impeller and air distributor of the flotation machine, a separation device, resulting in a reduction in the efficiency of the pulp delivery pump and the flotation machine. If not cleaned, it will also affect the quality of the final concentrate product. Content of the Utility Model

Detailed Embodiment

[0018] The following will further elaborate on the present utility model in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation manners are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0019] Embodiment 1: As Figure 1-2 shown, a detonator cord recovery device for the beneficiation and concentration process flow includes: a cylindrical screen cylinder body, a cylinder body bearing seat, a driving device, a recovery tank, filter holes, a pulp tank, a recovery tank support, a feed pipe, a partition plate, a flushing water pipe, and a recovery tank.

[0020] The cylindrical screen cylinder body is evenly provided with filter holes. Both sides of the cylindrical screen cylinder body are supported by the cylinder body bearing seats. The driving device outputs power to rotate the cylindrical screen cylinder body. A partition plate is welded inside the cylindrical screen cylinder body. During the rotation of the cylindrical screen cylinder body, the pulp with detonator cords enters the cylindrical screen cylinder body through the feed pipe. After the pulp is filtered through the filter holes of the cylindrical screen, it flows into the pulp tank to enter the next process. Since the shape of the ground detonator cords is irregular and flocculent, they are blocked by the filter holes inside the cylindrical screen. The detonator cords inside the cylindrical screen are brought above the cylindrical screen cylinder body along with the partition plate welded on the cylindrical screen cylinder body. A flushing water pipe is arranged outside above the cylindrical screen cylinder body. Under the action of the self-weight of the detonator cords and the external force of the pressurized water sprayed by the flushing water pipe, the detonator cords remaining on the cylindrical screen cylinder body are flushed and dropped into the recovery tank. The recovery tank has a certain inclination angle, and the flushing water and the detonator cords flow out together and enter the recovery tank, achieving the purpose of recovering the detonator cords.

[0021] For the detonator cord recovery device for the beneficiation and concentration process flow of the present utility model, the cylindrical screen cylinder body is a φ2m diameter cylinder rolled from an 8mm 316L stainless steel punching plate, with a length of 3m, a punching hole diameter of 10mm, one end being the driving side and the other end being the feed side, both being 8mm 316L stainless steel plates welded to the cylindrical screen cylinder body using a welding process.

[0022] For the detonator cord recovery device for the beneficiation and concentration process flow of the present utility model, both ends of the cylinder body are provided with support bearing seats using rolling bearings. The cylindrical screen cylinder body rotates under the drive of the driving device within the rolling bearings.

[0023] For the detonator cord recovery device for the beneficiation and concentration process flow of the present utility model, the recovery tank is of a trapezoidal structure and is fixed integrally with the recovery tank support with a 10% inclination angle, facilitating the outflow of the detonator cords outside the cylinder body.

[0024] For the detonator cord recovery device for the beneficiation and concentration process flow of the present utility model, the pulp tank is designed in a trapezoidal structure, and the upper surface of the trapezoidal structure is larger than the lower bottom surface size of the cylindrical screen cylinder body. The pulp tank is installed at the lower end of the cylindrical screen cylinder body to store and divert the filtered pulp.

[0025] The utility model relates to an environmental protection device for pressure filtration and dust removal, in which a partition plate is welded inside a cylindrical sieve barrel. There are 8 partition plates welded vertically at a uniform angle of 45°, made of stainless steel 316L, with a height of 50 mm, a thickness of 5 mm, and a length of 3 m, which serves to lift the detonator fuse.

[0026] The utility model relates to an environmental protection device for pressure filtration and dust removal, in which the flushing water pipe is a carbon steel pipe with a DN50 diameter, and a row of holes with a diameter of φ6 mm are drilled below it and vertically face the recovery tank, which serves to flush the detonator fuse inside the cylindrical sieve barrel.

[0027] Embodiment 2: As Figure 1-2 shown, the working principle of a detonator fuse recovery device for the beneficiation and concentration process flow involved in this embodiment is as follows:

[0028] Filter holes are uniformly arranged on the cylindrical sieve barrel body. The two sides of the cylindrical sieve barrel body are supported by the barrel bearing seats. The driving device outputs power to rotate the cylindrical sieve barrel body. During the rotation of the cylindrical sieve barrel body, the pulp with detonator fuses enters the inside of the cylindrical sieve barrel through the feed pipe. After the pulp is filtered through the filter holes of the cylindrical sieve, it flows into the pulp tank and enters the next process. Since the shape of the detonator fuse after being ground is irregular and in a flocculent shape, it is blocked by the filter holes inside the cylindrical sieve. The weight of the flocculent detonator fuse is very light, and the flocculent detonator fuse inside the cylindrical sieve is carried above the cylindrical sieve barrel body along with the partition plate welded on the cylindrical sieve barrel body. A flushing water pipe is arranged outside the upper part of the cylindrical sieve barrel body. Under the action of the self-weight of the detonator fuse and the external force of the pressure water sprayed by the flushing water pipe, the detonator fuse remaining on the cylindrical sieve barrel body is flushed and falls into the recovery tank. The recovery tank has a certain inclination angle, and the flushing water and the detonator fuse flow out together and enter the recovery tank, achieving the purpose of recovering the detonator fuse.

[0029] The above are only the preferred specific embodiments of the utility model. These specific embodiments are all different implementation manners based on the overall concept of the utility model, and the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the utility model should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
