Description
Technical field
The invention belongs to moulded coal preparation field, be specifically related to a kind of Bidirectional pressure forming machine that is applicable to various coal charges.
Background technology
Forming machine is the key equipment of briquette molding technique, and whether its structure rationally directly affects the Forming Quality of moulded coal.Forming machine has different types of machines, and the forming machine in early stage technology is mostly one direction, coal charge to be exerted pressure, but this unidirectional exerting pressure can make the stressed of coal charge successively decrease along direction of exerting pressure, and the moulded coal that has caused thus making exists the problem of global density inequality.
In order to overcome above-mentioned technical problem, a kind of pressure forming machine that can bidirectional pressing is provided in Chinese patent literature CN1039754A, this forming machine is except having oil cylinder 1, crossbeam 2, sidewall 3, base 4, pressing mold 5 and framed 6, also there is backform 7, upper arresting pin 8, lower limit pin 9 and spring 10.The course of work of this bidirectional hydraulic make-up machine is: pressing mold 5 moves downward, bulk cargo in framed is first exerted pressure from top, when the front portion of pressing mold 5 all enters in framed 6, rear portion is when framed 6 contact, the front portion of pressing mold 5 all enters in framed 6, rear portion is when framed 6 contact, exerting pressure of 5 pairs of bulk cargos of pressing mold stops, simultaneously framed 6 under the impetus of pressing mold 5 along with pressing mold 5 moves downward together, the top that is fixed on base 4 due to backform 7 is motionless, so moving downward along with pressing mold 5 and framed 6, backform 7 will be exerted pressure from below to framed 6 interior bulk cargos, until framed 6 contact with lower limit pin 9.Because this Bidirectional pressure forming machine can be exerted pressure to the bulk cargo being contained in framed respectively from upper and lower both direction, thereby solved the problem of the bulk cargo unbalance stress that existing pressure forming machine only causes from unilaterally exerting pressure.
Yet, above-mentioned bidirectional hydraulic make-up machine is when work, restriction due to described lower limit pin, the compression travel of described bulk cargo is restricted, but in practice process, different bulk coal meterials required compression ratio in making the process of moulded coal is different, and therefore above-mentioned Bidirectional pressure forming machine of the prior art can not be applicable to all coal charges.
In addition, above-mentioned forming machine of the prior art, owing to there is no exhaust apparatus, because gas cannot overflow, can produce gas enclosure layer in preparing the process of moulded coal in described moulded coal, and the existence of gas enclosure layer greatly reduces the intensity of described moulded coal.
Summary of the invention
In order to solve Bidirectional pressure forming machine of the prior art due to the restriction of compression travel, can not be applicable to all coal charges, and there is no exhaust apparatus, in preparing the process of moulded coal because gas cannot overflow, can in described moulded coal, produce the problem of gas enclosure layer, the present invention proposes a kind of Bidirectional pressure forming machine that is applicable to various coal charges and is provided with exhaust apparatus.
