[0002] Coke is an important raw material for metallurgy, casting, chemical industry and other industries, and its quality has a huge impact on production efficiency and product quality. In the metallurgical industry, the ash, volatile matter, fixed carbon, sulfur and other indicators of coke need to be tested before production. When sampling and testing coke, the existing sampling method is to manually smash the coke into uniform small pieces with a hand hammer, and then conduct the test. This method is inefficient, labor-intensive and time-consuming. Therefore, the industry urgently needs a coke sampling and pelletizing machine for testing. Utility Model Content

[0005] A sampling pelletizing machine for coke testing, comprising a base, a motor, a transmission belt, a central shaft, a lower box, an upper box, a feeding funnel, an upper cover, a feeding funnel, a large wear-resistant sleeve, a support shaft, a screen, a small wear-resistant sleeve, and a turntable; the lower box is mounted on the base, the upper box is fixed to the lower box by fasteners, a feeding funnel is arranged below the lower box, a feeding funnel is arranged above the upper box, and an upper cover is arranged on the feeding funnel; the central shaft is mounted on the base through a bearing seat, turntables are mounted on both sides of the central shaft, and the turntable is located in a cavity enclosed by the lower box and the upper box; both ends of the support shaft are respectively mounted on the turntable, a large wear-resistant sleeve and a small wear-resistant sleeve are mounted on the support shaft; the screen is mounted on the lower part of the lower box; the motor is mounted on the base, and the motor drives the central shaft to rotate through a transmission belt.

[0006] The above-mentioned sampling and pelletizing machine for coke testing has baffles installed inside the feeding funnel, with more than two baffles, the upper ends of which are hinged on the upper top plate of the feeding funnel, and the lower ends are suspended in a hanging shape.

[0007] The above-mentioned sampling and pelletizing machine for coke testing has four support shafts, which are evenly distributed on a circular track formed with the center point of the turntable as the center.

[0008] In the above-mentioned sampling and pelletizing machine for coke testing, the inner diameters of the large wear-resistant sleeve and the small wear-resistant sleeve are the same, both larger than the outer diameter of the support shaft; the outer diameter of the large wear-resistant sleeve is larger than the outer diameter of the small wear-resistant sleeve. When the two are mounted on the support shaft, two small wear-resistant sleeves need to be mounted close to each other, and then a large wear-resistant sleeve is mounted, and so on.

[0009] The utility model has the following advantages:

[0010] When using the sampling and pelletizing machine of the utility model, the large piece of coke to be tested is fed into the discharge funnel, and the motor is started. The large piece of coke will be crushed and squeezed and ground by the large wear-resistant sleeve and the small wear-resistant sleeve in the inner cavity formed by the lower box body and the upper box body, and the coke particles with the particle size meeting the requirements will leak out through the screen. Compared with manual operation, the sampling using the utility model is convenient and quick, and the work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] The utility model is a sampling pelletizing machine for coke testing, which is provided with a base 1, on which a motor 2 is mounted; a lower box body 5 is fixed on the base, an upper box body 6 is fixed to the lower box body by fasteners, a central axis 4 is mounted on the base 1 through a bearing seat, turntables 15 are mounted at both ends of the central axis 4, and both ends of a support shaft 12 are respectively fixed on the turntables 15; a feeding hopper 7 is provided at the upper end of the upper box body 6 for feeding materials into the pelletizing machine, and an upper cover 8 and an upper sealing top plate are provided at the top end of the feeding hopper 7; a feeding hopper 9 is provided below the lower box body 5 for collecting finished products.
