Technical Field

The invention relates to pulverized coal compression molding equipment, in particular to a machine for compressing pulverized coal into a sphere with a single through hole.

Background

The coal transported to the ground is mined, the coal powder is separated to the final product according to the granularity from large to small, the final product separated by the coal dry method is called the coal powder, the ash content is high, the heat value is low, the product separated and pressed by the coal wet method is called the fine coal powder, the ash content is low, and the heat value is high. The yield and the stock of the current coal dust and the refined coal dust are large, the yield is inevitable, the yield of coal exceeds 40 hundred million tons every year in recent years, the last coal dust and the refined coal dust are definitely large, the stock is large because the use of the coal dust and the refined coal dust is limited, the use amount is not large, and the stock is inevitably large because the environmental protection department does not allow the coal dust and the refined coal dust to be directly combusted in a boiler. A large amount of coal dust and fine coal dust are accumulated in a coal preparation plant, which not only accumulates capital and occupies the ground, but also outflows to pollute the ground surface environment when raining and also flies to destroy the atmospheric quality when blowing wind. It is urgent to find a way for pulverized coal and fine pulverized coal.

At present, a machine for pressing coal powder into uniformly distributed multi-hole cylindrical shapes is called a briquette machine and is also called a honeycomb briquette machine, a pressing mechanism is a crank sliding block mechanism, a first sliding block transmits force to a male die through a spring, a second sliding block transmits force to a punching column, the male die and the punching column jointly press the coal powder in a female die into briquettes, a higher-pressure forming area can be formed only by about 6 degrees in one turn of a crankshaft, the existing briquette machines belong to the category of low-pressure forming, the briquettes can be fully combusted only by stacking holes up and down when in use, the briquettes cannot be randomly filled and combusted in a boiler, and air holes are randomly blocked when the briquettes are randomly stacked, so that the phenomenon of insufficient combustion and resource waste is caused.

In order to change the phenomenon, the double-roller type ball forming mill has the advantages that the product is solid balls, the solid balls can be randomly stacked, the phenomenon that a ventilation channel is blocked does not exist, and the balls can be combusted in a boiler. The existing roller type ball forming machine has the problem that the high-pressure forming time is too short no matter a spring or a hydraulic oil cylinder applies pressure to a moving roller, the specific numerical value is that a high-pressure ball forming area can be formed only about 3 degrees when the roller rotates for one circle (360 degrees), the material can circulate from top to bottom when the quasi-solid ball lower boundary is above a pair of roller axis planes in the roller type ball forming mill, the material is closed when the quasi-solid ball lower boundary is on a pair of roller axis planes, the material can circulate from top to bottom when the sphere center of the solid ball is in a pair of roller axis planes, the material can circulate from top to bottom when the solid ball upper boundary is below a pair of roller axis planes, no matter where the quasi-solid ball or the solid ball is, the material has the problems of non-geometric sealing and outward flowing, a high-pressure ball forming area with geometric sealing can not be formed, and the required compression ratio can not be realized. Since the extrusion force in the 3-degree high-pressure forming area is approximately in cosine function distribution along the height direction of the solid ball, shear displacement and shear stress exist between layers of the coal ball in the height direction, so that the solid ball is low in balling efficiency and deformation and fracture caused by stress homogenization occur after aging. In addition, the solid ball is not suitable for being made into a large size or is not burnt thoroughly.

the reduction final drive assembly 21 includes a motor 23, a motor support assembly 24, a ninth key 2201, a small pulley 2202, a tenth key 2203, a large pulley 2204, a V-belt 2205, a first stage driving gear shaft 2101, a first stage driven gear 2102, a first key 2103, a second stage driving gear shaft 2104, a lower casing 2105, a second stage driven gear 2106, a second key 2107, a second stage driven shaft 2108, a third key 2109, a crankshaft support 2110, an output sleeve 2111, a fourth key 2112, a horizontal axis bevel gear 2113, a vertical axis upper bevel gear 2114, an upper casing 2115, a vertical driven shaft 2116, a fifth key 2117, a vertical axis lower bevel gear 2118 and a sixth key 2119.

The motor 23 is arranged at the inner right lower part of the lower box 2105 through the motor supporting component 24, the motor 23 drives the small belt pulley 2202 through the ninth key 2201, the small belt pulley 2202 drives the large belt pulley 2204 through the V-shaped belt 2205, and the large belt pulley 2204 drives the first-stage driving gear shaft 2101 through the tenth key 2203. The first driving gear shaft 2101 is engaged with the first driven gear 2102, the first driven gear 2102 drives the second driving gear shaft 2104 via the first key 2103, and the second driving gear shaft 2104 is engaged with the second driven gear 2106. The secondary driven gear 2106 drives a secondary driven shaft 2108 through a second key 2107,

the second-stage driven shaft 2108 drives an output sleeve 2111 through a third key 2109 to provide power for the crankshaft assembly 12.

The transmission ratio of the horizontal axis bevel gear 2113 to the vertical axis upper bevel gear 2114 is 1, the vertical axis upper bevel gear 2114 is connected to the vertical driven shaft 2116 through a fifth key 2117, and the vertical axis lower bevel gear 2118 is connected to the vertical driven shaft 2116 through a sixth key 2119.

The vertical shaft lower bevel gear 2118 and the horizontal shaft right bevel gear 2501 are meshed with each other, and the transmission ratio of the vertical shaft lower bevel gear 2118 to the horizontal shaft right bevel gear 2501 is 1, so that power is provided for the intermittent motion transmission assembly 25.

Rack

As shown in fig. 1, 3, 8, 18, 20 and 26, the frame is used for solving the problem of integral support,

the frame comprises a right front vertical beam 4, a right rear vertical beam 5, a left rear vertical beam 7, a left front vertical beam 8, a rear upper beam 201, a front upper beam 202, an upper beam transverse pin 203, an upper beam longitudinal pin 204, an upper beam transverse support plate 205, an upper beam transverse rib plate 206, an upper beam screw 207, an upper beam pin 208, an upper beam support 209, a lower box base screw 2120, a bottom plate 27 and a foundation bolt 30.

An upper beam cross plate 206 is welded on the upper surface of the upper beam cross plate 205, and a pair of upper beam supports 209 are welded on the lower surface of the upper beam cross plate 205, and the upper beam cross plate 205, the rear upper beam 201 and the front upper beam 202 are positioned through an upper beam pin shaft 208 and are fixedly connected through an upper beam screw 207. The left front vertical beam 8 and the right front vertical beam 4 are connected with the front upper beam 202 in an axle hole mode and fixed through an upper beam transverse pin shaft 203 and an upper beam longitudinal pin shaft 204, and the left rear vertical beam 7 and the right rear vertical beam 5 are connected with the rear upper beam 201 in an axle hole mode and fixed through the upper beam transverse pin shaft 203 and the upper beam longitudinal pin shaft 204. The left front vertical beam 8, the right front vertical beam 4, the left rear vertical beam 7 and the right rear vertical beam 5 are mounted on the left side of the bottom plate 27 in a shaft hole mode. The lower box 2105 is connected with the bottom plate 27 through lower box base screws 2120, and the bottom plate 27 is fixedly connected with the foundation through foundation bolts 30.
