Description

Technical Field

[0001] The invention relates to the technical field of ore dressing, in particular to a device for automatically removing debris without power. Background Art

[0002] In the mineral processing production of industrial and mining enterprises, a lot of pine wood is used as safety support in underground mining sites. It will eventually be transported to the mineral processing plant along with the ore. After being crushed and ground in the mineral processing plant, it will become sawdust, which is not conducive to the normal production of mineral processing and needs to be removed.

[0003] The traditional method of cleaning debris is to place a fixed screen on the overflow trough of the spiral grading, and the operator cleans the debris on the screen surface from time to time. The disadvantages are that it increases the labor intensity of the operator, and secondly, if the cleaning is not timely, it will cause the screen surface to be blocked and cause the loss of useful metal. Another way is to install a cylindrical screen. This method is effective, but it requires additional power drive and personnel operation, and occupies a large area. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a device for automatically removing debris without power, which includes a spiral classifier, a slurry chute and an arc screen trough; the spiral classifier and the slurry chute are respectively placed obliquely, and the slurry chute is respectively connected to the spiral classifier and the arc screen trough.

[0005] Wherein, the device also includes a debris receiving box.

[0006] Among them, the heights of the spiral classifier, the slurry chute, the arc screen surface trough and the debris receiving box are reduced in sequence.

[0007] Wherein, the height difference between the spiral classifier and the arc screen surface groove is 500~1000mm.

[0008] The arc screen surface groove is supported and fixed by a supporting frame, a bearing seat is fixed above the supporting frame, a main shaft is installed on the bearing seat, a supporting plate is fixed on the main shaft, a flexible scraper is also provided on the supporting plate, and the flexible scraper is fixed to the supporting plate by fastening bolts.

[0009] The arc screen surface groove is formed by bending a perforated iron plate screen with a thickness of 1.5-3mm, the bending radius of the screen surface is 500-1000mm, the diameter of the punching holes of the screen surface is 1.5-3mm, and the two ends of the curved screen surface are welded with a semicircular iron plate with a radius of 500-1000mm, and the thickness of the semicircular iron plate is 1.5-3mm.

[0010] Wherein, the support frame is formed by welding channel steel.

[0011] Wherein, the main shaft is made of a steel pipe with a diameter of 40-80 mm.

[0012] The support plate is made of flat steel with a width of 30-50 mm. One end of the support plate is fixed on the main shaft, and the other end is drilled with two small holes with a hole diameter between 13-20 mm.

[0013] Wherein, the flexible scraper is made of a conveyor belt with a thickness of 15-30 mm and is fixed on the supporting plate by fastening bolts.

[0014] Beneficial effects of the present invention:

[0015] The purpose of the present invention is to provide a device for automatically removing debris without power. The device is easy to manufacture, install and maintain, simple and practical to operate, and overcomes all the disadvantages of traditional methods. After the debris and unqualified mineral particles flow to the arc-shaped screen surface groove with the slurry, the flexible scraper automatically rotates under the impact of the slurry. The debris and unqualified mineral particles cannot pass through the sieve holes and are scraped out by the flexible scraper and collected in the debris receiving box. The qualified mineral particles directly pass through the sieve holes and enter the next ore dressing process. The device for automatically removing debris without power provided by the present invention realizes the characteristics of automatically removing debris without power, reduces the labor intensity of employees, and achieves the purpose of energy saving and consumption reduction.

[0029] Example 5

[0030] The present invention provides a device for automatically removing debris without power, wherein the height difference between the spiral classifier 1 and the arc screen surface groove 3 is 550 mm, the arc screen surface groove 3 is formed by bending a punched iron plate screen with a thickness of 2.5 mm, the screen surface bending radius is 500 mm, the screen surface punching hole diameter is 1.5 mm, and the two ends of the curved screen surface are welded to it with semicircular iron plates with a radius of 500 mm, and the thickness of the semicircular iron plates is 1.5 mm; the supporting frame 4 is welded with channel steel, the main shaft 6 is made of a steel pipe with a diameter of 70 mm, the supporting plate 7 is made of flat steel with a width of 40 mm, one end of the supporting plate 7 is fixed to the main shaft 6, and the other end is drilled with two small holes with a hole diameter between 14 mm, and the flexible scraper 8 is made of a conveyor belt with a thickness of 30 mm and is fixed to the supporting plate 7 by fastening bolts 9.

[0031] At present, mining enterprises use spiral classifiers to classify the products after grinding in mineral processing production. Unqualified coarse-grained ore returns to the ball mill through the spiral for re-grinding, and qualified fine-grained ore flows with the overflow water of the classifier to the next selection operation such as flotation, gravity separation, magnetic separation, etc. However, some debris on the mining site, such as pine wood, woven fibers, etc., will also enter the next selection operation with the overflow water of the spiral classifier after grinding. These debris will affect the next selection operation and need to be removed.

[0032] The device for automatically removing debris without power provided by the present invention is that when the overflow water of the spiral classifier 1 flows onto the arc screen surface groove 3, the support plate 7 and the flexible scraper 8 are pushed to make continuous circular motion around the main shaft 6 due to the flow kinetic energy and potential energy of the overflow water. Since the flexible scraper 8 is closely attached to the arc screen surface groove 3, the qualified ore contained in the overflow water of the spiral classifier 1 can pass through the sieve holes of the arc screen surface groove 3, while the debris contained in the overflow water cannot pass through the sieve holes of the arc screen surface groove 3 and is scraped out by the flexible scraper 8 and falls into the debris receiving box 10, thereby ensuring that the debris does not enter the next sorting operation, thereby improving the sorting environment, improving the sorting effect, and realizing the unpowered debris removal.

[0033] The above embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
