Abstract

The utility model discloses an energy saving and consumption reduction level four coal press, including one -level buffer unit (1), second grade buffer unit (2), tertiary buffer unit (3) and level four buffer unit (4), one -level buffer unit (1), second grade buffer unit (2), tertiary buffer unit (3) and level four buffer unit (4) communicate in proper order, air inlet pipeline (7) and one -level buffer unit (1) intercommunication, level four buffer unit (4) and pipeline (8) the intercommunication of giving vent to anger, one time one pipeline (5) are through pneumatic control valve and one -level import buffer (9) intercommunication, four times one pipeline (6) are through pneumatic control valve and one -level import buffer (9) intercommunication. The beneficial effects are that: one time one adjustment has reduced getting into the tertiary gas amount in coal press rear portion, reduces the tertiary acting volume in coal press rear portion, can reduce the power consumption of coal press by a relatively large margin, reaches reduce current's purpose.

Description

Energy-saving and cost-reducing level Four coal press machine

Technical field

This utility model relates to a kind of coal press machine, is specifically related to a kind of energy-saving and cost-reducing level Four coal press machine.

Background technology

Coal press machine regulative mode is: coal press machine closes a pneumatic fast valve after starting, coal press machine pressure is adjusted by four times control valves, when load is widely varied, move back the regulation of one-level cylinder tolerance by throwing to control, during underload, one-level cylinder tolerance regulation Periostracum Cicadae goes out, and during high load capacity, the regulation of one-level cylinder tolerance all puts into.After pressure stability, adjusting four times apertures, but the adjustment open range of four times is the least during combustion engine load slight fluctuations, after adjustment, the change of coal press machine running current is less, causes bigger station service to waste.Four times governor valve control are that the gas after coal press machine level Four is compressed returns one-level import, control pressure by adjustment tolerance and exert oneself with coal press machine.But level Four expellant gas is compressed through coal press machine level Four, be equivalent to return again to after coal press machine consumes rated power acting, inefficient.

Summary of the invention

The problem existed for above-mentioned prior art, this utility model provides one energy-saving and cost-reducing level Four coal press machine, it is to avoid the power consumption waste that one-level causes is returned in level Four aerofluxus again, also can reduce coal press machine electric current.

To achieve these goals, the technical solution adopted in the utility model is: a kind of energy-saving and cost-reducing level Four coal press machine, including first-level buffer unit, level 2 buffering unit, three grades of buffer cells and level Four buffer cell, first-level buffer unit, level 2 buffering unit, three grades of buffer cells and level Four buffer cell are sequentially communicated, air inlet pipeline connects with first-level buffer unit, level Four buffer cell connects with outlet pipe, one time a pipeline is connected with one-level import buffer by pneumatic control valve, and four times a pipeline is connected with one-level import buffer by pneumatic control valve.

The beneficial effects of the utility model are: control for one time one is that the gas after one stage of compression returns one-level import buffer, adjusts pressure again by controlling flow and exerts oneself；One time one adjustment, decreases the coal gas amount entering three grades of coal press machine rear portion, reduces the amount of work at three grades of coal press machine rear portion, can consume energy by reduction coal press machine by a relatively large margin, reduces the purpose of electric current；One-level aerofluxus simultaneously directly returns one-level import buffer, decreases level Four aerofluxus and returns the power consumption waste that one-level causes again, can reduce coal press machine electric current equally.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

In figure: 1, first-level buffer unit, 2, level 2 buffering unit, 3, three grades of buffer cells, 4, level Four buffer cell, 5, pipeline, 6, four times pipelines, 7, air inlet pipeline, 8, outlet pipe, 9, one-level import buffer.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, this energy-saving and cost-reducing level Four coal press machine, including first-level buffer unit 1,2, three grades of buffer cells 3 of level 2 buffering unit and level Four buffer cell 4, first-level buffer unit 1,2, three grades of buffer cells 3 of level 2 buffering unit and level Four buffer cell 4 are sequentially communicated, air inlet pipeline 7 connects with first-level buffer unit 1, level Four buffer cell 4 connects with outlet pipe 8, one time a pipeline 5 is connected with one-level import buffer 9 by pneumatic control valve, and four times a pipeline 6 is connected with one-level import buffer 9 by pneumatic control valve.

Combustion engine load relatively low and must three coal press machines when running, exit the regulation of gas compression pump one-level tolerance, control coal press machine exert oneself by opening the pneumatic control valve of a pipeline 5.Adjustment principle is: the pneumatic control valve of four times pipelines 6 cuts out zero-bit, controls level Four delivery temperature less than 145 degree.During regulation, the operational approach of fine setting, prevents hypotony or pressure oscillation bigger.
