Description

The invention relates to devices for removing (cutting) solidified materials from the surface of strip crystallizers and can be used in the chemical, petrochemical, coking, food and other industries.

The purpose of the invention is to increase the reliability of the device at various positions of the drum axis by creating a constant guaranteed uniform minimum clearance between the surface of the tape and the knife along its entire length.

FIG. I shows the proposed device, a general view; FIG. 2 is a view A of FIG. one; in fig. 3 - cut

BB in FIG. one; in fig. 4 shows a schematic position of the cutting device, in which a uniform tachor is provided between the cutting edge of the knife and the surface of the drum (tape). A device for removing the cured material from the surface of the mold ribbon contains a shearing knife I, made in the form of separate shearing elements 2, mounted close to each other and fixed to the plate 3, for example with screws. To enable adjustment of the size of the gap between the knife I and the tape 4, longitudinal grooves 5 are made in each shearing element 2. The ends of the plate 3 are fixedly connected to the lever

6, On the ends of the levers 6, the axles 7 are fixed, on which the support rollers are rotatably mounted.

8, in contact with the surface of the belt 4, the envelope of the drum 9 of the belt crystallizer. On the plate 3, at the same distance from the support rollers 8, the axis is fixed

10, which is installed with the possibility of turning in the sleeve 11 and secured therein by a nut 12 from vertical movement. The sleeve 11 is fixed perpendicularly fixed in the plate 13. On the lower plane of the plate 13 there are four lugs 14 of the same length, in which the ends of the string 15 are hinged. The other ends of the g 15 are fixed in the lugs 16 fixedly mounted on the base 17. At the same time the base 17 is located horizontally and parallel to the plane of the possible rotation of the axis of the drum 18

9. The rods 19 are attached to the plate 13 with weights 20 fixed on them, pressing the plate 13 with the sleeve 12 and, accordingly, the plate 3 with the knives 1 and the support rollers 8 to the surface of the belt 4 enveloping the drum 9 of the mold.

The device works as follows.

With a loose mounting of the shearing elements 2, by moving the weights 20 along the rods 19, the required force is applied to press the support rollers 8 to the surface of the belt 4, the envelope of the crystallizer drum 9. Then, controlling the gap between the shearing edges of the elements 2 and the surface of the belt 4, visually or with The probe (liners) installs the necessary clearance and secures each cutting element 2 of the knife 1, tightening the screws.

When the device is operating, the rollers 8, rolling along the surface of the tape 4 without detaching from it, lead the knife 1 along with them, ensuring a uniform gap between the cutting edge of the knife 1 regardless of the drawbacks of the drum 9 (ovality, radial runout, etc.). The knife 1 cuts off (cleaves) the layer of cured product 21, the rollers 8 provide the knife 1 to pass a rivet or weld tape seam without any mechanical effect on the seam. In addition, due to the fact that the plate 3 by means of the axis

10 is fixed so that it can be rotated in the sleeve II associated with the means for pressing the knife (weights 20) the rollers 8 are equally pressed against the edges of the belt 4, which guarantees the same force of pressing the knife along the entire length of its cutting edge and, accordingly, eliminates the possibility of penetration of the cooled product under the knife .

When the axis 18 of the drum 9 is rotated or skewed in either direction in the horizontal plane, caused by manual or automatic adjustment, for example, in order to center the tape stroke (keeping the tape in the middle position on the drums), the cutting edge of the knife 1 regardless of the magnitude and direction of the angle of rotation of the axis 18 the drum 9 is automatically installed exactly on the forming line of the drum 9. This is due to the fact that under the action of the load 20, pressing the plate 1 3 with the sleeve II and, accordingly, the plate 3 with the knife 1 to the drum 9, the plate 13 with volts And lkoy pivotally associated connecting rods 15 of equal length with the plane of the base 17, which is mounted parallel to the drum axis 18 of rotation of the plane 9 somewhat raised or lowered depending on the drum surface movement to the left or the right (FIG. 4). In this case, the axis of the sleeve 11 always remains perpendicular (in this case vertical) to the plane in which the axis 18 of the drum 9 moves (in this case in the horizontal plane). Under the influence of weights 20, the knife 10 rotates with the plate 3 and the axis 10 in the sleeve 11 until both rollers 8 stop against the surface of the belt 4, which envelops the drum 9, while the cutting edge of the knife 1 is automatically placed on the forming line of the drum. At the same time, the pressing force of each support roller 8 and, accordingly, the knife over the entire width of the drum is always constant, the gap between the cutting edge of the knife and the tape surface is also constant and guaranteed, which ensures high reliability and convenience in operation and expands the scope of application. A slight change in the position of the cutting edge of the knife along the vertical, as compared with the initial set of pressure, does not affect the process of cutting (accumulating) the solid product.

The device completely eliminates the possibility of damage to the surface and edges of the tape with a cutting knife; it does not require adjustment during operation of the cooling tape aggregates (crystallizers).
