After the pulverized coal falls from the upper parts of the two briquetting rollers, the two molding cavities on the briquetting rollers in the nearest state are mutually matched and compacted to form the briquettes. The ball press in the prior art has the following technical problems: firstly, the blanking devices of the ball press equipment adopt spiral blanking, and consume a large amount of electric energy; secondly, due to the fact that the diameter of the spiral is large, the coal powder filling position is located above the coal powder pelletizing area, the coal powder is extruded in the area, and the coal powder pressing roller and the coal powder generate great friction force to generate extra torque; the coal powder is injected from the area above the balling area, and because of the limitation of the limit compression ratio of the coal powder, the coal powder is compacted when not reaching the lower part, so that the extremely large extra pressure is generated in the horizontal direction in the rolling process; finally, the spiral blanking can not be carried out reasonably according to the compression ratio of different materials, so that the coal powder falling between the ball pressing rollers generates extra pressure on the roller and causes the problem of material turning, thereby reducing the balling rate and the balling quality.

Detailed Description
The technical solution of the present invention is further illustrated by the following two examples.
First embodiment, as shown in fig. 1 and 2, a non-spiral self-feeding ball press machine of the present embodiment is the same as a ball press machine in the prior art, and includes a frame 1 composed of a base 101 and a support 102, and two ball press rollers 5 arranged in parallel on the support 102. A plurality of hemispherical forming cavities 20 for pressing the coal powder into the coal balls are correspondingly arranged on the roller skins 4 of the two ball pressing rollers 5. In the process that the left-side ball pressing roller 5 and the right-side ball pressing roller 5 are controlled by the driving mechanism to rotate clockwise and anticlockwise synchronously, a ball forming area 21 is formed above the central connecting line of the two ball pressing rollers 5, and the pulverized coal falls into the ball forming area 21, is filled into the hemispherical forming cavities 20 and is gradually compacted until the two hemispherical forming cavities 20 are completely matched and then are formed, and is discharged from the lower parts of the two ball pressing rollers 5 along with the continuous rotation of the ball pressing rollers 5.
Different from the prior art, the feeding of the embodiment is realized by the self-blanking storage box 10 instead of a feeding screw, and the bottom of the self-blanking storage box 10 is provided with a primary blanking port 11; the coal dust isolation plates 9 are covered above the two ball pressing rollers 5, a coal dust buffer cavity 12 is formed in the space between the two coal dust isolation plates 9 and below the primary feed opening 11, and a secondary feed opening 13 is formed in the gap between the two coal dust isolation plates 9. The automatic discharging material storage box 10 is fixed at the top of the frame 1, and a large amount of electric energy consumption is saved by the ball press machine through gravity blanking, so that the production cost is reduced, and the production economic benefit is improved. The arrangement of the coal powder isolation plate 9 avoids that coal powder directly falls into the balling area 21 and is stored in the coal powder buffer cavity 12 on one hand, thereby avoiding that a great deal of coal powder is extruded to generate great friction on the roller skin 4 of the ball pressing roller 5; on the other hand, the two pulverized coal isolation plates 9 can be rotated to rotate along the circumferential direction of the corresponding ball pressing roller 5, so that the width of the secondary feed opening 13 can be adjusted according to the compression ratio required by pulverized coal. The feeding amount of the coal powder in the balling area 21 between the two ball pressing rollers 5 can be conveniently adjusted by the secondary feed opening 13, so that the phenomenon that the ball pressing rollers 5 generate great extra pressure in the horizontal direction due to compaction when the powder is not completely inosculated in the two corresponding hemispherical forming cavities 20 under the condition of excessive feeding is avoided.
In this embodiment, the cross section of the pulverized coal isolation plate 9 is in the shape of an arc corresponding to the peripheral radian of the ball pressing roller 5, the pulverized coal isolation plate 9 is covered above the ball pressing roller 5 along the length direction of the ball pressing roller 5, and the rotation center of the pulverized coal isolation plate 9 coincides with the roller center of the corresponding ball pressing roller 5. Two first supporting rods 8 which are distributed along the radial direction of the ball pressing roller 5 are fixedly arranged at any end of the coal powder isolation plate 9, and the end parts, far away from the coal powder isolation plate 9, of the first supporting rods 8 are fixedly connected to a rotating shaft 3 which is rotatably arranged in the support 102. The handle 2 used for shifting the pulverized coal isolation plate 9 to rotate is fixedly arranged on the rotating shaft 3, and after the pulverized coal isolation plate 9 is rotated to a proper position, the handle 2 can be fixed on the support 102 through the positioning pins and the positioning holes distributed on the support 102, so that the pulverized coal isolation plate 9 is fixed, and the width of the secondary feed opening 13 is fixed.
An angle dial 6 is fixedly arranged at the position of the bracket 102, which is positioned at the rotation center of the coal dust isolation plate 9, and a pointer 7 which is used for being matched with the angle dial 6 to display the rotation angle of the coal dust isolation plate 9 is fixedly arranged on the rotating shaft 3. The width of the secondary feed opening 13 can be visually displayed through the angle, so that the quantitative adjustment of an operator is facilitated.
As shown in fig. 3, the second embodiment is different from the first embodiment only in the rotation manner of the pulverized coal partition plate 9. In this embodiment, the lower portions of the two ball pressing rollers 5 are respectively covered with a weight plate 14, and an end portion of the weight plate 14 is fixed to the rotating shaft 3 through a second support rod 15. The arrangement of the counterweight plate 14 enables the gravity centers of the pulverized coal partition plate 9, the counterweight plate 14 and the rotating shaft 3 to be basically positioned at the axis center of the rotating shaft 3, thereby avoiding the excessive stress of the first support rod 8 in the first embodiment. Teeth distributed along the circumferential direction of the ball pressing roller 5 are arranged on the outer edge of the counterweight plate 14, and a rack 16 meshed with the teeth on the counterweight plate 14 is arranged on the base 101 in a sliding manner. The rack 16 is pushed to drive the counterweight block to rotate, and then the counterweight block-rotating shaft 3 drives the pulverized coal isolation plate 9 to rotate.
In order to further simplify the operation and achieve the purpose of synchronously controlling the rotation of the two pulverized coal isolation plates 9, in this embodiment, a slide way 18 for the two racks 16 to jointly slide and fit is arranged on the base 101, and the first slide way 18 is arranged on the base 101 corresponding to the center of the ball pressing roller 5 in the length direction. The two racks 16 are respectively in sliding fit through a T-shaped sliding block and sliding groove structure. A lead screw 17 is further rotatably arranged in the slideway 18, the left end of the lead screw 17 is installed in a rolling bearing at the left end of the slideway 18 in a matching way, and the right end of the lead screw 17 extends out of the base 101 and is connected with the output end of a worm gear mechanism 19 with a self-locking function. Nuts matched with the screw rod 17 are respectively arranged on the two racks 16, and the rotating directions of the two sections of threads matched with the screw rod 17 and the two nuts are opposite. Through the structure, the worm wheel or the motor drives the worm and gear mechanism 19 to further drive the screw 17 to rotate, so that the two racks 16 can be controlled to synchronously move along opposite or back-to-back directions, and then the two coal powder isolation plates 9 are driven to synchronously rotate by the meshing action between the racks 16 and the balancing weight. After the secondary feed opening 13 is adjusted to a proper width, the width of the secondary feed opening 13 is locked by the self-locking function of the worm and gear mechanism 19.
