Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-viscosity viscous material conveying equipment, in particular to a novel hydraulic discharging machine. BACKGROUND

[0002] In current industrial production, the conveying and processing of high-viscosity viscous materials are common technical problems faced by many fields such as chemical industry, food processing, pharmaceutical industry, and environmental protection. Such materials (such as high-molecular polymers, paste food raw materials, biomass slurry, and industrial waste residues) generally have poor flowability, strong cohesion, and easy adhesion, and the traditional conveying equipment has significant limitations in actual application.

[0003] The commonly used screw conveying equipment in the prior art often faces the problem of rapid increase in energy consumption caused by excessive torque of the transmission mechanism when processing extremely high-viscosity materials, and the viscous friction between the material and the screw easily causes temperature rise effect, affecting the quality of heat-sensitive materials. Although the plunger type extrusion device can provide a larger thrust, its intermittent operation mode leads to poor conveying continuity, and the reciprocating motion mechanism has defects such as fast wear of sealing elements and high maintenance frequency. For viscous materials containing solid particles or fiber components, the narrow flow channel of the traditional equipment is prone to material blockage, and in severe cases, it may even cause equipment downtime for maintenance, seriously affecting production efficiency.

[0004] Although the air pressure driven conveying equipment developed in recent years has improved power output to some extent, it has inherent problems such as large pressure fluctuation and unstable extrusion flow due to the compressibility of gas, which makes it difficult to meet the process requirements of precision production processes. In addition, the modularity of existing equipment is generally low, and when faced with materials with different physical parameters, the entire set of adaptive components often needs to be replaced, resulting in high equipment use cost.

[0005] Based on the above technical bottlenecks, the industry urgently needs to develop a new type of conveying equipment that has large thrust output, stable continuous conveying, strong material adaptability, and low maintenance requirements to break through the technical barriers in the processing of high-viscosity viscous materials.
