Description

TECHNICAL FIELD

[0001] The utility model belongs to iron ore processing technical field especially, it is a kind of automatic impurity removing device of sampling point. BACKGROUND

[0002] In the beneficiation stage of iron ore processing field, to ensure the quality of beneficiation product meets the standard, the beneficiation plant usually adopts the way of sampling in time to carry out quality monitoring to beneficiation product. Generally speaking, every interval 1 hour, the beneficiation plant will sample and test to flowing beneficiation product. The purpose of this process is to feed back test result to operating post in time, so as to not only test product quality, but also provide guidance for post operation.

[0003] In the specific sampling process of beneficiation product, beneficiation product is first concentrated through flow tank, then makes self-flow to thickener using the natural slope of flow tank, carries out subsequent processing process. In this link, cutting pipe as sampling device is vertically placed in flow tank. When flowing beneficiation product passes through cutting pipe, a small part of beneficiation product will self-flow to sampling point through the gap reserved in cutting pipe, that is cutting port, and then sampling personnel will carry out sampling operation at sampling point.

[0004] However, in actual operation, grass root, wood chip and other sundries in raw ore are often mixed in beneficiation product (concentrate or tailings), these sundries and a small amount of coarse particles often block cutting pipe. When ore sample reduces, due to the change of component composition ratio of beneficiation product, it will cause deviation of test result, and cannot accurately reflect the real quality of beneficiation product. More seriously, when cutting pipe is completely blocked, no ore sample flows out, sampling operation cannot be carried out, which not only affects the normal production process of beneficiation plant, but also can seriously affect subsequent product quality control.

[0005] Therefore, how to design a new type of automatic impurity removing device of sampling point, which can automatically remove sundries, prevent cutting pipe from being blocked, and ensure sampling accuracy and continuity, has become a problem to be solved in current iron ore processing field.

[0025] II. Impeller Section 1

[0026] Material: Made of 0.15mm thick iron plate.

[0027] Dimensions: Blade length 80mm; Blade width: 40mm (both sides); Blade angle 45 degrees; Outer ring diameter 145mm; Outer ring width 15mm; Outer ring thickness 0.15mm.

[0028] Structure: Four blades are welded equally to the outer ring, and the blades are firmly welded to the outer ring to ensure structural stability.

[0029] III. Scraper 2

[0030] Material: High-strength iron rod with a square cross-section.

[0031] Dimensions: Length 160mm; Cross-sectional side length 10mm.

[0032] Structure: There are two scraper rods, which are equally welded to the upper sliding ring 6 and the lower sliding ring 3 respectively, ensuring that the two scraper rods 2 are on the same plane, and the included angle of the two sides of any scraper rod 2 is opposite to the included angle of the two sides of the other scraper rod 2, so as to ensure the scraping effect.

[0033] IV. Slip Ring

[0034] The slip ring section includes an upper slip ring 6 and a lower slip ring 3, both designed as follows:

[0035] Materials: All are made of iron rings with a diameter of 45mm and an appropriate thickness (the specific thickness is determined according to actual needs).

[0036] Dimensions: Diameter 45mm; Length (height) 20mm.

[0037] Structure: The upper sliding ring 6 directly serves as the connection point for the scraper 2, ensuring the stability of the scraper 2. The lower sliding ring 3 is welded parallel to the center of the impeller section 1 by three 5mm×5mm×0.15mm iron plates, ensuring the stability of the lower sliding ring 3 and maintaining an appropriate distance from the impeller section 1.

[0038] V. Positioner 4

[0039] Materials: 45mm diameter iron rings are used, with the thickness determined according to actual needs to ensure sufficient strength and stability.

[0040] Dimensions: Diameter 45mm; Length (height): 20mm.

[0041] Structure: Eyelets are made at opposite positions at both ends of the iron ring, and M8 nuts are inserted into the eyelets. These eyelets and nuts are designed to allow the screw to pass through, thereby fixing or adjusting the position of the positioner 4.

[0042] VI. Installation and Operation

[0043] The entire device should ensure that the connections between all components are firm and stable, and that operation is smooth without significant vibration or noise. Through proper installation and adjustment, the scraper 2 should be able to effectively remove impurities around the sampling point, improving work efficiency.

[0044] VII. Precautions

[0045] 1. During the manufacturing process, it is essential to ensure that the dimensions and angles of each component are accurate to guarantee the normal operation of the device.

[0046] 2. During the welding process, attention should be paid to welding quality and safety to ensure that the weld is firm and free from defects such as incomplete welds or missing welds.

[0047] The specific implementation of the new automatic cleaning device for sampling points is as follows:

[0048] First, install the positioner 4 at the bottom of the cutting pipe 5 and tighten it in place with a screw. Then, fit the impeller assembly 1 onto the cutting pipe 5, with the bottom of the sliding ring 3 completely fitted against the positioner 4.

[0049] Due to the impact force of the slurry flow, the impeller 1 begins to rotate automatically around the receiving pipe 5. This rotation drives the scraper 2 between the slip rings connected to the impeller 1. Driven by the impeller 1, the scraper 2 makes a circular motion around the receiving pipe 5.

[0050] During the movement of scraper 2, its tip (the angle between the two sides of the iron rod) continuously scrapes away various debris and mineral particles embedded in the gap of the cutting pipe 5. This process is real-time and automatic, requiring no manual intervention, ensuring unobstructed access to the sampling point.

[0051] The slip ring structure design ensures that the scraper 2 remains stable during its circular motion, preventing it from shifting or wobbling. This stability guarantees that the scraper 2 can accurately and effectively remove debris and mineral particles from the feed inlet of the feed pipe 5.

[0052] The novel automatic cleaning device for sampling points utilizes the impact force of the slurry flow to drive the movement of the impeller 1 and scraper 2, achieving real-time automatic cleaning of the guide gaps in the intercepting pipe 5. This implementation not only improves the continuity and accuracy of sampling but also greatly facilitates the production operations of the mineral processing plant.
