Abstract
The utility model discloses a loose connection-preventing scraping knife for a pelletizer. The loose connection-preventing scraping knife is composed of a scraping knife rod and a ceramic scraping knife head connected with one end of the scraping knife rod, wherein a spiral slot is arranged on the scraping knife rod; a cap-shaped fixed supporting plate is arranged on the scraping knife rod with the spiral slot; a blocking slot matched with the spiral slot on the scraping knife rod is arranged in a groove of the cap-shaped fixed supporting plate; the scraping knife rod with the spiral slot is arranged in the groove of the cap-shaped fixed supporting plate; a bolt hole matched with a screw hole on the base of a scraping knife bracket is arranged on the cap edge of the cap-shaped fixed supporting plate; the cap-shaped fixed supporting plate is connected with the base on the scraping knife bracket by a bolt. The scraping knife disclosed by the utility model is firm in connection, capable of effectively ensuring that scraping knives arranged on the fixed bracket are operated on the same horizontal plane, easy to change, and further capable of reducing maintenance times, and improving pelletizing quality and capacity.
Description
Technical field
The utility model relates to a kind of scraper, specifically belongs to a kind of pelletizer scraper.
Background technology
Scraper is the key process components on pelletizing pelletizer, disk pelletizing is in rotary course, be to be cleaned and struck off by the scraper mineral that adhere on end liner of being tried to get to the heart of a matter, the disc balling machine end liner of trying to get to the heart of a matter is more smooth, and its machine utilization is lighter, pelletizing material rollability in disk is better, the formation of mother bulb and mother bulb coarsening rate are faster, and compactness is better, and the irregular large ball most importantly producing is few, unit unit-hour output is high, and quality of green pellets is good.Therefore, keep scraper particularly important in good technology state for a long time.The try to get to the heart of a matter flatness of lining of ball, not only has substantial connection with the diameter of scraper head, material, abrasion resistance, scraper rotating speed and mating of ball dish rotating speed etc., meanwhile, still has important relation with the strong degree that is connected of scraper.
At present, the fixed form of round its scraper of pelletizer using all adopts clamping plate type to fix, that is: on every pelletizer, be provided with two circular scraper fixed mounts, on each circular fixed mount, distinguish in proportion the scraper base of prefabricated installation scraper, on each scraper base, there is screw, scraping cutter bar is vertically close to scraper base central authorities, then seat supporting semicircle clamping plate in You Yikuaiyu hole clamp scraping cutter bar, and 4 screws are tightened fixing.Due to pelletizer disk and doctor blade holder disk difference relative rotary motion, often cause part scraper loosening, cause installed many scraper not in one plane, and effectively at the bottom of clean disk, cause ball try to get to the heart of a matter lining be uneven, affected the running of material in ball dish.Then make usage factor, balling property, the green ball strength of card all produce decline phenomenon.And can be due to scraper loosening, cause screw thread slide fastener in scraper base, and need maintenance in time, affect normal operation, and increase maintenance workload.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of scraper to connect firm, can effectively guarantee that the scraper of installing on fixed mount all moves on same horizontal plane, reduce the pelletizer scraper of the anti-loosening connection of repair and maintenance number of times.
Realize the technical measures of above-mentioned purpose:
A pelletizer scraper for connection, it is comprised of scraping cutter bar, the resistance ceramic scraper head that is connected with scraping cutter bar one end, and it is: on scraping cutter bar, be provided with helicla flute; On band spiral fluted scraping cutter bar, fixedly supporting plate of hat is housed, at hat, is fixedly provided with the draw-in groove matching with helicla flute on scraping cutter bar in the groove of supporting plate; With spiral fluted scraping cutter bar, be placed in hat fixedly in the groove of supporting plate; At hat, be fixedly provided with the bolt hole that the screw on the base with scraper support matches on the shade of supporting plate; Hat fixedly supporting plate is connected with the base on scraper support by bolt.
Feature of the present utility model is: it is firm that pelletizer connects with scraper, can effectively guarantee that the scraper of installing on fixed mount all moves on same horizontal plane, and easily change, and can also reduce repair and maintenance number of times, improves quality and the production capacity of pelletizing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the fixing structural representation of supporting plate of hat in Fig. 1;
Fig. 3 is that the A of Fig. 2 is to structural representation;
In figure: 1-scraping cutter bar, 2-resistance ceramic scraper head, 3-screw, 4-helicla flute, 5-hat is supporting plate fixedly, 6-groove, 7-draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
A pelletizer scraper for connection, it is comprised of scraping cutter bar 1, the resistance ceramic scraper head 2 that is connected with scraping cutter bar 1 one end.It processes helicla flute 4 on scraping cutter bar 1; The fixing supporting plate 5 of processing hat, at the hat draw-in groove 7 that fixedly the interior processing at least one of groove 6 of supporting plate 5 matches with helicla flute 4 on scraping cutter bar 1, is placed in hat fixedly in the groove 6 of supporting plate 5 by the scraping cutter bar with helicla flute 41; At the hat screw 3 that fixedly screw on the base of processing and scraper support matches on the shade of supporting plate 5; Hat fixedly supporting plate 5 is connected with the base of scraper support by screw 3.
Because scraping cutter bar 1 is stuck in hat fixedly in the groove 6 of supporting plate 5, and there is draw-in groove 7 to coordinate with helicla flute 4, cause resistance ceramic scraper head 2 can only carry out in allowed limits bob, therefore effectively prevented significantly play and affect the phenomenon of production of scraper.
This specific embodiment only exemplifies for the best, not the restricted enforcement to the technical program.
