Problems solved by technology

[0005] However, the existing binder forming technology adopts a simple pressing device and a simple process, which may easily cause insufficient compaction of the pulverized coal. The molding device cannot realize direct demoulding, and a separate demoulding device needs to be installed, which increases the complexity of the process

Abstract

The invention relates to the technical field of coal dust forming and provides a hydraulic forming device used for compacting coal and a control method thereof. The hydraulic forming device used for compacting coal comprises a hydraulic machine body, a hydraulic pump, an oil tank, a computer, a control device and an oil pipe. The hydraulic machine body comprises a hydraulic cylinder, an operation platform, a hydraulic machine top plate and support uprights. The hydraulic pump is connected with the hydraulic cylinder via the oil pipe, the oil tank is connected with the hydraulic pump and is used for storing hydraulic oil, a measuring control module is mounted on the computer, and the control device comprises a switch and a USB interface. The control method can compact raw coal into coal briquette by the hydraulic forming device. The hydraulic forming device can meet the technical needs of coal forming, equipment requirements for the adhesive forming technology are lowered, and coal forming process can be well controlled by control software of the computer.

Description

technical field [0001] The invention relates to the technical field of pulverized coal molding, in particular to a hydraulic molding device for pressing coal briquettes and a control method thereof. Background technique [0002] As the fifth largest transportation mode in my country, pipeline transportation is a supplement and improvement to the modern transportation system. As an important branch of pipeline transportation, pipeline hydraulic transportation has been widely used in recent years, mainly used to transport some solid bulk materials. On this basis, the hydraulic transportation technology of briquette coal pipeline has been developed. The basic idea of ​​hydraulic transportation of briquette pipelines is to firstly press the coal powder particles into a waterproof and wear-resistant cylindrical coal pillar, then inject the coal pillar into the pipeline, use pressurized water as the carrier fluid, and use the pump power to carry the coal pillar for a long time. ...
