Description

Technical Field

[0001] The invention relates to the field of centrifuge discharging, in particular to a scraping structure for a centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions. In an existing centrifuge, after work is completed, the separated solid material is discharged through a discharge pipe. The discharge pipe is a cylindrical shape that opens vertically downward. Since the material separated by the centrifuge is wet, it is easy to stick to the wall of the discharge pipe when discharging, and it is difficult to discharge without external force. The Chinese invention patent with application number 202222040004.5 discloses a scraping structure for a centrifuge, including a connecting member and a scraper. The connecting member is rotatably mounted on the end of the discharge pipe, the scraper is fixedly connected to the connecting member, and the scraper abuts against the wall of the discharge pipe. The scraper is used to scrape off the solids stuck to the wall of the pipe.

[0003] The scraping structure of the above patent scrapes the material on the wall of the feeding pipe with a vertical scraper. Problems were found during use: the structure rotates circumferentially to move the material, and most of the material is scraped up and discharged under gravity, but the structure does not have a structure to scrape the material downward. Since it is relatively solid and moist, there will be residue on the inner wall of the feeding pipe. Moreover, it can only be adapted to one feeding pipe, not to feeding pipes of different diameters, and its scope of application is limited. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a scraping structure for a centrifuge. The scraping structure is provided with a structure for scraping materials downwards, which can scrape materials downwards to avoid residues in a discharge pipe and is adaptable to a variety of types of discharge pipes, effectively solving the problems raised in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: a scraping structure for a centrifuge, comprising an annular base, wherein the upper surface of the base is embedded with a plurality of annular grooves from the outside to the inside for matching with the lower port of the feed pipe, and the outer surfaces of the left and right sides of the fixed seat are respectively provided with first screw holes penetrating the annular grooves inwardly, and a first bolt is screwed into the first screw hole;

[0006] Circular fixing blocks are fixedly arranged on the front and rear sides of the central hole of the base respectively. The fixing blocks and the bottom surface of the outer annular groove are provided with vertical through holes. A scraper which can slide up and down is inserted in the front and rear through holes.

[0007] As a preferred technical solution, the scraper includes a scraper with an arc-shaped top, and a connecting block is provided on the inner side of the scraper. A second bolt is screwed through the connecting block downward, and the second bolt is threadedly connected to the top of the vertical sliding rod. A second screw hole that cooperates with the second bolt is embedded in the top of the sliding rod.

[0008] As a preferred technical solution, a transverse screw sleeve is fixedly provided on the base at the outer end of the first screw hole, and the screw sleeve is concentrically arranged with the first screw hole.

[0009] As a preferred technical solution, pull rings are fixedly provided at the bottom of the slide rods.

[0010] As a preferred technical solution, the diameter of the through hole is larger than the outer diameter of the sliding rod.

[0011] As a preferred technical solution, a blade is fixedly provided on the bottom surface of the scraper.

[0012] As a preferred technical solution, the lower end of the blade is inclined outwards.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a scraping structure for a centrifuge includes an annular base 1, and a plurality of annular grooves 11 are embedded from outside to inside on the upper surface of the base 1, which are matched with the lower port of the discharge pipe 5. The outer surfaces of the left and right sides of the fixed seat 1 are respectively provided with first screw holes 12 penetrating the annular grooves 11 inwardly, and the first bolts 3 are screwed from outside to inside in the first screw holes 12. Circular fixing blocks 14 are respectively fixed on the front and rear sides of the center hole of the base 1, and vertical through holes 13 are provided on the fixing blocks 14 and the bottom surface of the outer (front and rear) annular grooves 11, and scraping members 4 that can slide up and down are inserted in the front and rear through holes 13 (only the innermost group is shown in the figure).

[0029] The scraper 4 includes a scraper plate 41 with an arc-shaped top. A connecting block 42 is provided on the inner side of the scraper plate 41. A second bolt 43 is screwed through the connecting block 42 downward. The second bolt 43 is threadedly connected to the top of a vertical slide rod 44. A second screw hole 441 cooperating with the second bolt 43 is embedded in the top of the slide rod 44.

[0030] A transverse screw sleeve 2 is fixedly disposed on the base 1 at the outer end of the first screw hole 12 , and the screw sleeve 2 is concentrically disposed with the first screw hole 12 .

[0031] Pull rings 45 are fixedly provided at the bottom of the slide rods 44 .

[0032] The diameter of the through hole 13 is larger than the outer diameter of the slide bar 44 so that the slide bar 44 can swing at multiple angles, which is beneficial to scraping the material on the inner wall of the feed pipe 5.

[0033] When in use, by setting a number of annular grooves 11, it is convenient to match with the lower end of the feeding tube 5 of different diameters, which is convenient to expand the scope of application. The first bolt 3 can be screwed from the outside to the inside to press the feeding tube 5 to prevent the base 1 from slipping. The slide bar 44 can pass through the through hole 13 from the bottom to the top, and the scraper 41 can be installed on the top through the second bolt 43. The scraper 41 can be produced in various models. The corresponding model is selected according to different feeding tubes 5. Then, the front and rear two groups of scrapers 41 cooperate with the vertical sliding slide bar 44 (which can slide together or separately), which can scrape the material inside the feeding tube 5 downward. The sleeve 2 cooperates with the first bolt 3, which is convenient for the outermost annular groove 11 to be firmly fixed to the feeding tube 5. The pull ring 45 is convenient for the staff to grasp and pull the slide bar 44 downward.

[0034] Example 2

[0035] like Figure 5 As shown, a blade 411 is fixedly provided on the bottom surface of the scraper 41. The lower end of the blade 411 is inclined outward.

[0036] When in use, the blade 411 further enhances the scraping effect of the material. The outward inclination is conducive to sticking to the inner wall of the lower material pipe 5.
