Multi-cylinder double-group circulation type hydraulic particle bar making machine

Abstract

The invention belongs to the machinery industry, and particularly relates to a multi-cylinder double-group type hydraulic particle bar making machine. Two fixed templates I (1) are fixedly mounted in the front of the upper surface of a platform rack (14) in parallel, two fixed templates II (7) are fixedly mounted in the rear of the upper surface of a platform rack (14) in parallel, the rear ends of two main oil cylinders (8) are fixedly connected with a supplementing oil tank (10) which is arranged above the front side of an oil tank (20), an overflow pipe (29) is mounted on the side wall above the right side of the supplementing oil tank (10) and connected with the oil tank (20), moving template slide rails (28) are fixed on the upper surface of the platform rack (14), compression bars at the front ends of moving templates (6) are movably arranged in pre-pressing cylinders (15), the front ends of the pre-pressing cylinders (15) are connected with compression cylinders (3) respectively, the front ends of the compression cylinders (3) are connected with the rear ends of the fixed templates I (1) respectively through die sleeves (2), and a material hopper (5) is arranged between the two pre-pressing cylinders (15). The multi-cylinder double-group type hydraulic particle bar making machine is compact in structure, stable, reliable and convenient to maintain, the production cost is reduced, the extrusion force is large, the density of a finished product obtained through extrusion is good, and the burning heat value is high.

Description

technical field [0001] The invention belongs to the machinery industry, in particular to a multi-cylinder double-group circulating hydraulic granule rod making machine. Background technique [0002] In rural areas, a large amount of straw is produced every year, and many of them are set on fire in the field, which not only pollutes the environment but also poses a fire hazard. In order to solve this problem, people from all walks of life have started to think about it. After years of exploration, people began to make straw into pellets for use. The use of boilers for heating in winter has led to widespread market demand for this environmentally friendly and cheap fuel. In order to meet market demand, many manufacturers have produced a variety of pellet-making equipment, but some of these equipment have low production efficiency and high production costs. Some equipment has low pressure, small density of extruded particles, and low combustion calorific value, which is difficu...
