Detailed Description
In order to make the technical means, the characteristics and the purpose of the present invention easy to understand, the embodiment and the specific implementation of the disc pelletizer having the scraper assembly provided by the present invention will be further described.
The disc pelletizer is divided into a pelletizer base 7, a pelletizer disk 6, a pelletizer disk motor, a frame 5, a scraper motor 3 and a scraper mounting rack 2. Balling disk 6 inclines to the horizontal plane and installs on pelletizer frame 7, and balling disk motor is installed at balling disk 6 back for it is rotatory to drive balling disk 6, and frame 5 erects on balling disk frame 7, is equipped with motor mounting bracket 4 in the frame 5, is used for installing scraper motor 3, and 3 lower extreme transmission parts of scraper motor link to each other with scraper mounting bracket 2, and the scraper is installed on scraper mounting bracket 2. The scraper still divide into the balling scraper and clears away material scraper 1, the scraper divide into cutter arbor and tool bit two parts, the balling scraper tool bit is ceramic material bar-shaped structure, and bar-shaped structure makes it can scrape 6 bed charge of balling disk when balling and does not influence the effect of balling again, and ceramic material can increase the wear-resisting degree of balling scraper tool bit, and uses for a long time and can not lead to the fact the damage to balling disk 6. The material cleaning scraper 1 has a cone-shaped cutter head 14, and the cutter head 14 is close to but not in contact with the balling disc.
Furthermore, in the embodiment, the cross section of the scraper head of the material cleaning scraper is in a plurality of pointed teeth shapes, and the surface of the cone body is in a prism shape.
Further, in this embodiment, the scraper mounting frame 2 is a circular ring 24 structure including a central shaft 21, the circular ring 24 is fixed on the central shaft 21 through a long connecting strip 22 and a short connecting strip 23, the central shaft 21 is located on a vertical line passing through the center of the circular ring 24 and is connected with a transmission part of the scraper motor 3, and a plurality of scraper mounting positions 25 are arranged on the circular ring 24.
Further, in the embodiment, the scraper mounting position 25 is a pressing structure, the pressing structure is composed of a fixing plate 251 and a pressing plate 252, the pressing structure is a hoop-shaped structure in a pressing state so as to pass through the scraper arbor 11, the fixing plate 251 is fixed on the circular ring 24, the pressing plate 252 is removed when the scraper is mounted, the scraper arbor 14 faces the balling disk 6, the scraper arbor 11 is mounted on the fixing plate 251, and then the scraper is pressed on the fixing plate 251 and fixed through the pressing plate 252.
Further, in this embodiment, the fixing plate 251 is fixed to the ring 24 of the scraper mounting frame 2 by screws, and the pressing plate 252 is fixed to the fixing plate 251 by screws at four corners.
Furthermore, the middle section of the cutter bar 11 of the material cleaning scraper 1 is provided with a fixed section 12 with the diameter smaller than the rest part, the fixed section 12 is pressed by the tabletting structure when the material cleaning scraper 1 is installed, and the structure of the fixed section 12 ensures that the material cleaning scraper 1 can not slide up and down when in use, thereby avoiding damaging the pelletizing disc 6 or weakening the cleaning effect.
Furthermore, in the embodiment, a plurality of scraper mounting positions 25 are provided, and different numbers of pelletizing scrapers can be mounted according to the requirement of the actual pelletizing granularity. Because scraper motor 3 drives scraper mounting bracket 2 rotatoryly in this embodiment during the pelletizer function, make the pelletizer scraper itself just be doing rotary motion, and a plurality of pelletizer scrapers can be installed to scraper mounting bracket 2, increase the contact number of times of scraper and pelletizing dish 6 in the unit interval when making the pelletizer function, make the bed charge mix more evenly and scrape the effect of 6 bed charges of pelletizing dish better, in order to improve the spherulite shaping speed, can also increase and last pelletizing time.
Furthermore, because the backing material needs to be cut apart and removed through the prismatic structure on the material cleaning scraper 1 when removing the backing material of the pelletizing disc, so as to prevent the material cleaning scraper 1 from rotating when removing the backing material to cause the slip force, for this reason, the two point-like protrusions 13 are symmetrically designed on the fixing section 12 in this embodiment, so that the backing material of the pelletizing disc cannot rotate when being removed.
Furthermore, the bottom of the blade head 14 of the material cleaning scraper 1 in this embodiment is further designed with a plurality of blade head protrusions 14 for increasing the effect of removing the base material.
Further, the cleaning scraper 1 in this embodiment is made of high strength alloy, so that it is not easily blunted and the cleaning effect is not reduced when the backing material is removed.
Furthermore, in this embodiment, the balling disk 6 is further provided with a ceramic backing plate 8, and the surface of the ceramic backing plate 8 has a certain roughness, so that the wear resistance of the balling disk 6 can be increased, the service life of the balling disk can be prolonged, a certain friction force can be provided, and the balling quality and the balling speed can be increased.
Further, in this embodiment, two motor mounting brackets 4 are included on one machine frame 5, two sets of scraper mounting brackets 2 with different diameters are installed, and different numbers of motor mounting brackets 4 and scraper mounting brackets 2 with different diameters can be installed according to requirements during actual pelletizing or during bottom material removal.
Further, the balling disk motor and the scraper motor 3 in the embodiment can be replaced by variable frequency motors, and different rotating speeds can be set according to different requirements in use.
The implementation of this example is as follows:
install the balling scraper on scraper installation position 25 before using this disc pelletizer balling, start balling disk 6 motor, it is rotatory to drive balling disk 6, start scraper motor 3 simultaneously, it is rotatory to drive scraper mounting bracket 2 in balling disk 6, mix the mixture that iron raw materials and adhesive are good according to setting for the even joining balling disk 6 of material volume, balling disk 6 is rotatory to take the balling material to balling disk 6 interior relative high position, tiny water droplet is added to the centre, in the meantime owing to constantly reinforced and add water and balling disk 6's rotation, the mother ball constantly rolls, compress tightly, and glue balling material manifold cycles, the qualified green ball of certain intensity and granularity has been formed. However, after the pelletizing operation is carried out for a long time, the bottom material in the pelletizing disc is adhered to form a bottom material layer, so that the pelletizing quality is affected, and the adhered bottom material of the pelletizing disc needs to be removed in time. The method comprises the steps that before backing materials are cleared, a worker detaches a pelletizing scraper, then a pit is dug manually on a backing material layer at the position of a pelletizing disc corresponding to the scraper mounting position 25, so that the material cleaning scraper 1 can be smoothly mounted, the material cleaning scraper 1 is mounted at the scraper mounting position 25, a certain amount of water is added into the pelletizing disc 6, finally, a pelletizing disc motor and a scraper motor 3 are started, the pelletizing disc is operated, and the backing materials of the pelletizing disc are cleared by the material cleaning scraper 1 through mechanical movement of the pelletizer during operation.
