Problems solved by technology

At present, the use of coal is still very unreasonable. It is quite common to burn raw coal in industrial boilers and kilns, which causes problems such as low combustion efficiency and excessive emissions of sulfur dioxide and smoke. Coal burning pollution has always been troubled by the environmental protection department. Treatment of small and medium-sized coal-fired industrial boilers, and the realization of total control of soot-type air pollution

Embodiment Construction

[0015] The multi-circuit modulus hybrid electro-hydraulic control furnace front forming machine has a coal hopper 5, a roller, a motor and a reducer device 4, a coal gate 6, a front arch 7, a drive sprocket 3, and a chain or a fixed grate 8; , high-precision modulus hybrid control system 1, electro-hydraulic control system 2 for automatic control of the forming strength and the operation of the furnace former forming machine; the driving shaft is a transverse axial groove, the driven shaft is a longitudinal circumferential groove, the pressed shape The coal is two intersecting arc surfaces; the briquette pressure can be adjusted from 30 to 150kg / cm 2 .

[0016] The so-called programmable controller control system uses the computer system to control the hydraulic control device through the interface circuit and the programmable controller through analog-to-digital conversion, and controls the hydraulic control device through digital sensors and analog sensors. Carry out real-t...

Abstract

The forming machine before furnace includes a coal bunker, a pair of forming rollers, motor, reduction device, coal gate, front arch, driving chain wheel, chain or fixed grate. It adopts computer and programmable controller control system and electro-hydraulic control system to automatically control forming strength and operation of said forming machine before furnace, Its driving shaft has transverse axial recess, and its drive shaft has longitudinal circular recess, and the pressed briquette has two crossed cambered surfaces, the briquette pressure can be regulated. Said ivnention utilzies the combination of digital control technology and mechanical technology so as to possesses the advantages of reliable and simple operation, long service life of forming rollers and high-for ming rate, etc.

Description

technical field [0001] The invention relates to a multi-circuit modulus mixed electro-hydraulic control furnace front molding machine. Background technique [0002] China's coal ranks second in the world, and it is one of the few countries that uses coal as the main energy source. The coal industry is an important pillar industry in my country. At present, the use of coal is still very unreasonable. It is quite common to burn raw coal in industrial boilers and kilns, which causes problems such as low combustion efficiency and excessive emissions of sulfur dioxide and smoke. Coal burning pollution has always been a problem for environmental protection departments. Treatment of small and medium-sized coal-fired industrial boilers, and the realization of total control of soot-type air pollution. The industrial coal briquette technology was researched and developed during the national "Seventh Five-Year" scientific and technological research period in the 1980s. In 1996, Hangzh...
