Problems solved by technology

The ball briquetting machine in the prior art has the following technical problems: firstly, the feeding device of the briquetting machine equipment adopts screw feeding, which consumes a lot of electric energy; secondly, due to the large diameter of the screw, the pulverized coal filling position is above the ball forming area, Squeeze the pulverized coal in this area, and the pressure ball roller will have great friction with the pulverized coal to generate additional torque; the pulverized coal is injected from the area above the ball forming area. When it reaches the bottom, it has been compacted, resulting in a huge extra pressure in the horizontal direction during the rolling process; finally, the screw feeding cannot be properly fed according to the compression ratio of different materials, so that the coal falling between the ball pressing rollers Powder creates extra pressure on the rollers and causes turnover problems, reducing pelleting rate and pelleting quality

Embodiment 1

[0022] Embodiment one, such as figure 1 and figure 2 As shown, a kind of non-screw self-feeding briquetting machine of the present embodiment is the same as the briquetting machine in the prior art, and both include a frame 1 made up of a base 101 and a bracket 102 and a frame 1 arranged in parallel on the bracket 102. Two pressure ball rollers 5. A plurality of hemispherical cavities 20 for pressing coal powder into briquettes are correspondingly provided on the roller skins 4 of the two briquetting rollers 5 . During the synchronous rotation of the left pressure ball roller 5 clockwise and the right pressure ball roller 5 counterclockwise by the driving mechanism, a ball forming area 21 is formed above the line connecting the centers of the two pressure ball rollers 5. After entering into the ball zone 21, it is filled into the hemispherical forming cavity 20 and is gradually compacted until the corresponding two hemispherical forming cavity 20 are completely matched and ...

Abstract

The invention relates to the field of coal briquette processing equipment, in particular to a ball press machine featuring non-spiral self discharging. The ball press machine comprises a rack and twoball press rollers arranged on the rack in parallel. A plurality of semispherical forming cavities used for pressing pulverized coal into coal briquettes are formed in roller skins of the two ball press rollers correspondingly. The ball press machine further comprises a self-discharging storage box and two pulverized coal isolation plates which are arranged on the rack from top to bottom in sequence and located above the two ball press rollers. A first-stage discharging port is formed in the bottom of the self-discharging storage box. The two pulverized coal isolation plates cover the upper portions of the two ball press rollers correspondingly. A pulverized coal temporary storage cavity is formed in a space between the two pulverized coal isolation plates and located below the first-stagedischarging port. A second-stage discharging port is formed in a gap between the two pulverized coal isolation plates. The two pulverized coal isolation plates can rotate in the circumferential directions of the corresponding ball press rollers, so that the width of the second-stage discharging port is adjustable. According to the ball press machine featuring non-spiral self discharging, electricenergy consumption can be reduced, the ball press rollers are prevented from being subjected to unnecessary acting force in the coal briquette pressing process, and accordingly, the service life is prolonged.

Description

technical field [0001] The invention relates to the field of briquette processing equipment, in particular to a non-spiral self-cutting briquetting machine. Background technique [0002] China is a big country in coal storage, production and consumption, and coal consumption accounts for more than 70% of the country's energy consumption. Coal is the main source of energy for urban residents in my country, accounting for more than 80% of urban civil energy consumption. Most of the residents in our country use raw coal scattered combustion, which not only has low thermal efficiency, but also pollutes the environment. With the gradual strengthening of environmental protection requirements, industrial briquette processing has become an environmental protection and resource comprehensive utilization industry encouraged by the state, which is in line with national and regional industrial policies. Briquette technology is one of the seven technologies for the industrialization of ...
