置を提供するものである。(Problems to be Solved by the Invention) The scraping arm 5 is made of a thick plate having a trapezoidal cylindrical cross section as shown in FIG. 2, and has a scraping knife 4 fixed to the upper end of one longitudinal side. Among the horizontal plates of the scraping arm 5, the plate 5' on the back side of the basket is not perpendicular to the falling direction of the cake like the other longitudinal plates but is tilted diagonally due to space constraints within the machine, so it is difficult to scrape. If the removed solids tend to adhere, they may grow into lumps, making it impossible to discharge the cake. The present invention has been made to solve the problems of the prior art described above, and provides a new scraping device for a horizontal scraping type centrifuge.

掻取装置である。Means for Solving the Problems) The gist of the present invention is to provide a horizontal centrifuge that scrapes with a scraping arm that has a side surface that slopes inward toward the bottom of the inner surface of the basket and has a trapezoidal cylindrical opening cross section. In the scraping device of the machine, one end of the scraping rod made of an arcuate elastic body is rotatably supported at the upper end of a discharge chute provided directly below the scraping arm in the direction of rotation of the scraping arm. A guide groove is provided at the lower end of the inclined surface of the arm to slidably hold the scraping rod.
This scraping device for a centrifugal separator is characterized in that the tip of the other end of the scraping rod is movable in contact with an inclined surface of a scraping arm.

る。 In the figure, the reference numerals are the same as in FIG. 5, and 5 is a cylindrical scraping arm having a trapezoidal opening cross section, and a ruler-shaped scraping knife is attached to the upper end of its long side. Reference numeral 5' denotes an inclined surface of the scraping arm, which occurs due to the internal structure of the basket of the horizontal scraping type centrifuge. Reference numeral 6 indicates a discharge chute provided directly below the scraping arm for discharging the scraped cake to the outside of the machine, and 7 indicates rotation of the basket in order to scrape the cake layer K laminated on the inner surface of the basket using the scraping arm 5. The rotating shaft rotates the basket radially outward in opposite directions, and is driven by a hydraulic cylinder (not shown). Reference numeral 9 denotes a scraping rod made of an elongated piece of elastic material having an arcuate shape, and is made of stainless steel or other elastic metal such as an elongated round rod or square rod. The reason why it is long and thin is to prevent cake from adhering to the scraping rod itself. One end of the scraping rod 9 is rotatably supported by a rod support member 10 at the upper end of the discharge chute 6 on the rotating surface of the scraping arm 5. This end may be spirally wound to increase elasticity. Reference numeral 11 denotes a guide groove cut away from the lower end of the inclined surface 5' of the scraping arm, and is shaped so that the scraping rod 9 can be engaged and slidably moved therein.

離に有効である。Operation) The operation of the present invention having the above configuration will be explained. When the cake layer K on the inner surface of the basket reaches a predetermined thickness, the rotating shaft 7 is moved by a hydraulic cylinder.
is rotated to rotate the scraping arm 5 outward in the radial direction of the basket, whereby the scraping knife 4 comes into pressure contact with the cake layer K, and the powdery solids C are discharged outside the machine via the discharge sheet 6. Ru. On the other hand, when the scraping arm 5 is on the inside in the radial direction, the scraping rod 9 is in the state shown in FIG. Pressure welding begins, and the powdery cake adhering to the inclined surface 5' is scraped off while gradually descending to the state shown in Figure 4. At this time, the scraping rod 9 is held in the guide groove 11, so it falls to the left and right. The tip hits perpendicularly to the inclined surface 5' and can effectively scrape off the lumpy cake adhering to the inclined surface 5'. The scraping arm 5 scrapes off the cake layer, and when it reaches the base layer, it returns to the initial position, but at this time as well, the tip of the scraping rod 9 comes into contact with the slope in the opposite direction to the one used during scraping, so that the adhering cake is peeled off. It is effective for

ステムなので省力的である等の効果がある。Effect) Since the cake that adheres to the inclined surface 5' of the scraping arm can be removed while operating, there is no need to stop operation every now and then to remove the cake that has adhered, which increases the operating rate of the centrifuge. In particular, since the system uses the rotation of the scraping arm 5 itself to remove the adhering cake, it is labor-saving and other effects.
