Abstract

The present invention relates to devices for sampling loose melted materials from rotary kilns with their free fall and can be used in non-ferrous and ferrous metallurgy, chemical and cement industries. The device makes it possible to increase the representativeness of sampling and the reliability of operation of the device due to the change in the location of the fall of the bulk material from the rotating chamber. The device contains a rotating cylindrical working chamber 1, placed in the case of the hot head 2, a sampling organ executed in the form of a tube, connected by means of a connecting element 4 to the axis 5 of the actuator 6. The tube is extended with a longitudinal cutout. inside the hot head 2, and the axis of rotation 5 of the sampling body with the actuator 6 is mounted on the outside near the sampling window 8 on the frame 9 at an angle of 25-40 to the axis of rotation of the rotating cylindrical working chamber 1.

The invention relates to sampling devices, in particular, devices for sampling bulk hot materials from rotary kilns with its free fall, and can be used in ferrous and ferrous metallurgy enterprises, in the chemical and cement industries ..

The aim of the invention is to increase the representativeness of sampling and the reliability of the device due to a change in the location of the fall of the bulk material from the rotating chamber.

FIG. 1 shows the proposed device, a general view of FIG. 2, section A-A in FIG. 1, the position of the selection.

 The device for sampling bulk materials contains a rotating cylindrical working chamber 1 placed in the body of the hot head 2 a sampling body made in the form of a tube 3 connected by means of a connecting element 4 to the axis 5 of the actuator 6. The tube 3 is made with a longitudinal cut 7 in the upper part and placed inside the hot head 2, and the axis of rotation 5 of the sampling body with the actuator 6 is installed outside the sampling window 8 on the frame 9 at an angle of 25-40 to the axis of rotation 5 of the rotating cylindrical working 1. amers Krsh1ka 10 is rigidly secured to the connecting member 4, and a body mounted probo- .otbornym receiver 11 samples.

The device works as follows.

Before sampling, a sampling window 8 is installed inside the chamber of the hot head 2 in the upper position. For sampling, the tube .3 is rotated by actuator 6 by 90 °, at the same time crossing the flow of material. Then, when the tube 3 is rotated in the opposite direction, a sample is taken, which is caught by the notch 7 in the upper part of the tube 3 and poured into the sample receiver 11. The position of the clamp 10 between the tube 3 and the axis of rotation 5 and fixing it to the connecting element 4 allows samples and automatic opening and closing of the sampling window 8 with the same actuator 6.
