Single driving synchromesh corrugated-surface roller press

Abstract

The invention relates to a single driving synchromesh corrugated-surface roller press which is used for smashing material, wherein the driving synchromesh corrugated-surface roller press comprises a main rack; two dentate extruding rollers, which is arranged on the main rack, wherein one of the rollers is a corrugated fixed roller, the other is a corrugated movable roller, the extrusion surfaces of the corrugated fixed roller and the corrugated movable roller are respectively provided with a multiple of mutually matched corrugated fixed roller grinding units and corrugated movable roller grinding units, a material extruding channel is formed between the corrugated fixed roller grinding units and the corrugated movable roller grinding units, and material enters the material extruding channel to perform extruding; a dual-output synchronous reduction gear, which is connected with the two dentate extruding rollers; and a motor, which is connected with the dual-output synchronous reductiongear, wherein the motor controls the two dentate extruding rollers to synchronously rotate by the dual-output synchronous reduction gear. The single driving synchromesh corrugated-surface roller presseffectively avoids abrasion of the roller surface caused by relative sliding due to unequal linear velocity of the roller surfaces of the dentate extruding rollers and reduces the energy consumption,and the powder selecting efficiency is promoted.

Description

technical field [0001] The invention relates to a rolling press, in particular to a single-drive synchronous meshing corrugated surface rolling machine. Background technique [0002] The working mechanism of the roller press of prior art is as figure 1 As shown, the two extrusion rollers 101, 102 are driven by respective transmission systems 103, 104 and universal couplings 105, 106, wherein the first extrusion roller 101 is a movable roller, and the movable rollers are paired by a group of hydraulic cylinders 107 Pressurized, the material is squeezed and pulverized in the extrusion channel formed by the cylindrical surfaces of the two extrusion rollers 101, 102, and discharged from the machine. The material extrusion channel is composed of two outer cylindrical surfaces, and the critical clamping angle nominal value When the material enters the extrusion channel, it is extruded under high pressure by two extrusion rollers 101 and 102 that rotate synchronously in opposite d...

Problems solved by technology

[0004] 1. Since the two grinding systems are driven by independent motors, the motor slips are not exactly the same in the strict sense, which leads to unequal instantaneous speeds of the two grinding rollers, and the two grinding rollers with different speeds are extruding There will be relative sliding when the material is moving, which will not only increase the wear of the roller surface, but also increase the friction power consumption;

[0005] 2. Due to the vibration and impact of extrusion grinding, the power configuration of the motor must have greater redundancy. The redundancy coefficient of the small-power motor is higher than that of the high-power motor, so the line loss and reactive power loss are also obvious. Big;

[0006] 3. Studies have shown that the critical clamping angle of the extrusion channel formed by the outer cylindrical surface of two grinding rollers is 6°, and the extrusion channel formed by the outer cylindrical surface of one grinding roller and a plane (such as a vertical roller mill) The critical clamping angle of the pressure channel is 12°, and the critical clamping angle of the extrusion channel formed by an outer cylindrical surface and an inner cylindrical surface (such as a roller mill) can reach 23.5°. Therefore, the traditional roller press machine clamps into the mill The material of the roller must be less than 5% of the diameter of the grinding roller. In order to prevent the material from slipping out under pressure, a higher material level pressure is usually used, which also indirectly increases the energy consumption, and also produces the edge effect of the roller press, making the roller Press damage
