Description
Technical field
The present invention relates to a kind of special equipment of fine coal system rod.
Background technology
Machine for producing coal bars is a kind of extrusion principle that utilizes, with the equipment of the coal dust extrusion modling that is mixed with the sodium humate bonding agent, once in the early 1980s of extensive use in the small-sized nitrogen of China, phosphorus, potash fertilizer chemical enterprise.But because its output is little, efficient is low, the incompatibility large-scale industrial production is eliminated gradually.Along with rising steadily of current market lump coal price, each nitrogen, phosphorus, potash fertilizer chemical enterprise are heavily walked the road of the relatively low type coal gas of cost again one after another under the pressure of the pressure of surviving.The coal rod spiral squeezing type machine for producing coal bars that is adopted mainly contains 3 kinds of forms such as spiral squeezing type, pneumatic extrusion type and hydraulic pressure squash type; The power of extruding of spiral squeezing type machine for producing coal bars is pushed fine coal by helical blade to discharge opening; Because helical blade only has portion of energy to be converted into axial propelling movement power in rotary course; Produce in the head place to extrude power limited; The briquette prod difficult quality is up to standard, and has defectives such as power consumption is big, failure rate of machinery is high, and the complete machine cost is high, the consumable accessory consumption is big, production environment is abominable.Pneumatic extrusion type machine for producing coal bars is to adopt the cylinder of air compressor to push the work forward; " the high-efficiency energy-saving pneumatic extrusion type machine for producing coal bars " (notification number: CN1903557 that is better than application on July 31st, 2006 patent of invention like zhuzhou, hunan province city Shifeng District Zhou Jia pool casual household's No. 2 Wang Guang; Number of patent application: 200610032043.3); It discloses a kind of machine for producing coal bars that adopts pneumatic fashion of extrusion to operate; Because of its extruding promotes the compressed air of the motive force of cylinder from air compressor, and the maximum pressure that common cylinder can bear is in 1Mpa; Receive the restriction of its pressure, the cylinder bore of the energy-saving pneumatic extrusion type machine for producing coal bars that production capacity is 3～4t/h reaches 600mm usually, and the cylinder bore of the energy-saving pneumatic extrusion type machine for producing coal bars that production capacity is 5～8t/h reaches 700mm usually; But receive the condition restriction such as materials used and manufacturing and processing equipment of cylinder, maximum gauge is big greater than the cylinder manufacture difficulty of 700mm, and cost is high; And energy-saving pneumatic extrusion type machine for producing coal bars need be equipped with corollary equipments such as screw-rod air compressor, air accumulator and gs-oil separator, increased subscriber equipment cost and maintenance cost greatly.And because head is divided into left and right sides two parts, tens discharging sleeves are housed between left head and the right head, for guaranteeing the correct assembling of discharging sleeve in the middle of left head and right head; Require the tolerance of pitch-row between left head and the right head assembling discharging sleeve ground reference hole to be ± 0.025mm; Required precision is very high, and its processing and assembling have been put forward very high requirement, and general common metal cutting processing mechanical apparatus can't reach its requirement; Need to adopt the processing of numerical control metal cutting processing mechanical apparatus; Cause processing cost high, be difficult to realize ordinary production, operation is also very inconvenient.This application people used hydraulic transmission mode afterwards again instead; And applied for utility model patent " high-efficiency and energy-saving type fluid pressure type machine for producing coal bars " (notification number: CN201128243 on December 04th, 2007; Number of patent application: 200720065305.6); It comprises circular cylinder body, place pressurizing unit in the circular cylinder body, be arranged at the head in circular cylinder body exit, and pressurizing unit adopts fluid pressure drive device, is controlled at by the HYDRAULIC CONTROL SYSTEM device and makes to come and go rectilinear motion in the cylindrical shell.Though effect improves to some extent, because of it is to adopt single cylinder list piston form to drive, because the distance of operation is longer, the piston rod easy deformation.Influence ordinary production, and machinery is damaged easily,, also is difficult to by realizing industrialization on this technical scheme basis through the experiment in 2 years.
