Description

Technical Field

[0001] The utility model relates to an adaptive material cleaning device for the disc extension of a disc pelletizer, belonging to the technical field of pellet production equipment in the metallurgical industry. Background Art

[0002] A disc pelletizer is a device for producing green pellets. After the powder material is added into the disc and wetted with water, it continuously tumbles to form material particles - small pellets - large pellets. When the small pellets roll towards the middle of the disc and continue to grow, they roll towards the edge of the disc and are discharged. The discharged large pellets are green pellets, and their moisture content is between 7.50% and 9.0%. When the green pellets pass from the disc extension of the pelletizing disc to the belt, the disc extension will adhere to some sticky materials. Over time, it will cause the accumulation of materials on the disc extension, affecting the process of the green pellets entering the belt, thus increasing the pelletizing time and further affecting the particle size of the green pellets. At the same time, it increases the drop height of the green pellets entering the belt, affecting the internal density of the green pellets. Therefore, if the sticky materials on the disc extension of the pelletizing disc cannot be effectively cleaned, the quality of the green pellets will deteriorate. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adaptive material cleaning device for the disc extension of a disc pelletizer, which can effectively stabilize the working state of the scraper, improve the material cleaning effect, and solve the problems existing in the background art.

[0004] The technical solution of the utility model is as follows:

[0005] An adaptive material cleaning device for the disc extension of a disc pelletizer includes a first scraper, a second scraper, a support rod, a buffer spring, a fixed crossbeam, a hinge seat and a fixed bracket. On the disc extension of the disc pelletizer, two scrapers are successively arranged in the rotation direction of the disc pelletizer: the first scraper and the second scraper. The first scraper and the second scraper are respectively fixed on the support rod. One end of the support rod is hinged on the hinge seat, and the hinge seat is fixed on the fixed crossbeam. The fixed bracket is located above the support rod, and a buffer spring is arranged between the fixed bracket and the support rod.

[0006] The upper end of the buffer spring is connected to the fixed bracket, and the lower end of the buffer spring is connected to the support rod.

[0007] The connection part of the lower end of the buffer spring and the support rod is located between the first scraper and the second scraper.

[0008] The widths of the first scraper and the second scraper match the width of the disc extension of the disc pelletizer.

[0009] The fixed bracket is fixed on the fixed crossbeam, and the fixed crossbeam is located above the disc extension of the disc pelletizer.

[0010] The beneficial effect of the utility model is that the utility model adopts a double - scraper design and utilizes buffer elasticity at the same time, which can effectively stabilize the working state of the scraper and improve the material cleaning effect. Brief Description of the Drawings

[0011] Figure 1 It is a schematic structural diagram of the present utility model;

[0012] In the figure: the first scraper 1, the second scraper 2, the support rod 3, the buffer spring 4, the fixed cross beam 5, the hinge seat 6, the fixed support 7, and the pelletizing disc extension 8. Detailed Embodiment

[0013] The following further illustrates the present utility model through examples in conjunction with the attached drawings.

[0014] Referring to the attached Figure 1 , an adaptive material cleaning device for the pelletizing disc extension of a disc pelletizer, comprising a first scraper 1, a second scraper 2, a support rod 3, a buffer spring 4, a fixed cross beam 5, a hinge seat 6, and a fixed support 7. On the pelletizing disc extension 8 of the disc pelletizer, two scrapers are arranged successively in the rotation direction of the disc pelletizer: the first scraper 1 and the second scraper 2. The first scraper 1 and the second scraper 2 are respectively fixed on the support rod 3. One end of the support rod 3 is hinged to the hinge seat 6, and the hinge seat 6 is fixed on the fixed cross beam 5. The fixed support 7 is located above the support rod 3, and a buffer spring 4 is provided between the fixed support 7 and the support rod 3.

[0015] In this embodiment, referring to the attached Figure 1 , the adaptive material cleaning device for the pelletizing disc extension of the disc pelletizer is composed of a first scraper 1, a second scraper 2, a support rod 3, a buffer spring 4, a fixed cross beam 5, a hinge seat 6, a fixed support 7, and the pelletizing disc extension 8. Among them:

[0016] The width of the pelletizing disc extension 8 is 130 mm. The first scraper 1 and the second scraper 2 have the same specifications, and their width is 140 mm. The first scraper 1 and the second scraper 2 are respectively fixed on the support rod 3. The first scraper 1 and the second scraper 2 are in contact with the pelletizing disc extension 8 by their own weight. The support rod 3 is made of steel pipe. One end of the support rod 3 is connected to the hinge seat 6 by bolts. The hinge seat 6 and the fixed support 7 are welded on the fixed cross beam 5. The fixed support 7 is located directly above the steel pipe support rod 3. The support rod 3 is suspended on the fixed support 7 through the buffer spring 4, and the suspension point is located between the first scraper 1 and the second scraper 2.

[0017] The working process of the present invention is as follows:

[0018] The pelletizing disc rotates in the clockwise direction. The sticky material on the pelletizing disc extension 8 is scraped off by the first scraper 1 and the second scraper 2. For the sticky material at the bent or deformed position of the pelletizing disc extension 8, the buffer spring 4 can enable the two scrapers to better adhere to the surface of the pelletizing disc extension 8, achieving an ideal material cleaning effect.
