Description
Technical field
The utility model relates to brown coal extruding upgrading field, relates in particular to a kind of brown coal extrusion dehydration forming machine.
Background technology
Fewer and feweri along with coal resources, people also start more and more to pay attention to brown coal, and the research of brown coal is also more and more valuable.Brown coal, have another name called bavin coal, one class of coal, the sepia of a kind of degree of coalification between peat and bituminous coal, lacklustre grizzle, on section, can clearly be seen that original wooden vestige, it is the humic coal that peat forms through diagenesis, degree of coalification is minimum, so brown coal will be utilized, just must first obtain through refining processing, so brown coal contain interior water, wanting upgrading first needs to dry the part of its outer water, then drying its energy water, yet in the time of the upgrading of internal water, need to first destroy the interior molecules structure of its inner brown coal, we just need to carry out extrusion modling to brown coal like this, destroy its inner molecular structure composition, in extrusion modling, also can give an extruding part out by the internal moisture of brown coal simultaneously, reach dehydrating effect.Brown coal are for extrusion modling, are on the one hand to process readyly for upgrading again, and be to be convenient to transportation and to prevent moisture regain and design for the brown coal after upgrading on the other hand.
At present, prior art is generally drying and processing to the processing of brown coal, but after drying, brown coal are stacked easily generation spontaneous combustion and blast, is difficult for storing, and easily gets damp again, and is not suitable for transportation.
Utility model content
The utility model overcome above-mentioned the deficiencies in the prior art provide a kind of extrude brown coal internal moisture and brown coal be squeezed into piece be beneficial to the brown coal extrusion dehydration forming machine of depositing and transporting.
The technical solution of the utility model is achieved in that a kind of brown coal extrusion dehydration forming machine, comprise frame, brown coal hopper, brown coal discharge bucket, main shaft, motor, spindle pulley, motor pulley, belt, bearing block and pressurizing unit, described main shaft is arranged on bearing block, a terminal pad is installed in described main shaft upper end, terminal pad is connected with main shaft by flat key, pressurizing unit described in being provided with two on described terminal pad, described pressurizing unit comprises extrusion roll shaft, bearing, compression roller and extrusion die, on described terminal pad, offer two symmetrical circular holes, two described extrusion roll shafts are arranged on respectively in circular hole, two extrusion roll shafts link together by a plate, described in two, compression roller is set with extrusion die outward, described extrusion die comprises top board, lower platen and the Die and mould plate being clipped in the middle, Die and mould plate comprises polylith die unit, polylith die unit distributes ringwise, on described top board, lower platen, be provided with the bolt of fixed mold plate, top board, the lower platen of described extrusion die are all fixed in frame.
Bearing in described pressurizing unit is taper roll bearing, is socketed with the taper roll bearing described in two described in each on extrusion roll shaft.
Described in polylith, die unit is uniformly distributed ringwise, die unit large outer little cavity in forming described in every adjacent two.
Described in each, on extrusion roll shaft, be socketed with two for the dustproof palace type sealing device of bearing.
Equal two jackscrews on palace type sealing device described in each.
Round nut and the stop washer of axial compression bearing are installed on described extrusion roll shaft.
The good effect that the technical solution of the utility model realizes is as follows: this brown coal extrusion modling dewaterer is extruded brown coal internal moisture, and brown coal are squeezed into bulk, it is an indispensable part in brown coal upgrading, because this part is mainly to solve the self-destruction that occurs in brown coal upgrading and the phenomenon of spontaneous combustion, this extrusion modling is simultaneously to be better upgrading processing, after brown coal extrusion modling, change the interior molecules composition of brown coal, in extrusion modling, also squeezed out some inner moisture of brown coal itself.Simultaneously brown coal are extruded after moulding, are convenient to transportation, reduce flying upward of lignite dust, also prevent brown coal in inferior moisture regain, for prerequisite preparation has been done in the storage of brown coal.Round nut is joined stop washer, and axial compression bearing portions, to prevent axial float.Adopt two groups of taper roll bearings, both can bear axial load, can bear larger radial load again; The sealing of bearing adopts the shape sealing of the good palace of effect, prevents that bearing from receiving the pollution of dust.Compression roller adopts the form of two parts assembling, is not only convenient to processing and installs, and is also convenient to change in the situation that damaging.Extrusion roll shaft adopts eccentric form, for the extruding of brown coal provides larger power.Described in each, on extrusion roll shaft, be socketed with two for the dustproof palace type sealing device of bearing, equal two jackscrews on palace type sealing device described in each, palace RunddichtringO further seals bearing, and jackscrew holds out against palace type sealing device, and sealing effectiveness is better.

The specific embodiment
Brown coal extrusion dehydration forming machine, as Fig. 1, 2, 3, 4, 5, 6, shown in 7, comprise frame 1, brown coal hopper 2, brown coal discharge bucket 3, main shaft 4, motor 5, spindle pulley 6, motor pulley 7, V-belt, bearing block 8 and two pressurizing units, spindle pulley is arranged on one end of main shaft by flat key, main shaft is arranged in bearing block, the in-built upper bearing (metal) of bearing block, spindle pulley is connected to transmit power with motor pulley by V-belt, electric machine rotation can drive main shaft to rotate, the other end of main shaft is connected with terminal pad 12 by flat key, on terminal pad, offer two about the centrosymmetric circular hole of terminal pad, described pressurizing unit comprises extrusion roll shaft 9, two taper roll bearings 10 are installed on extrusion roll shaft, and taper roll bearing is socketed compression roller 11 outward, and extrusion roll shaft is arranged in the circular hole on terminal pad, the upper end of two extrusion roll shafts links together by a plate 13, carries out relative position and fixes, described compression roller is socketed extrusion die outward, extrusion die comprise top board 14, lower platen 15 and be clipped in top board and lower platen between Die and mould plate 16, described Die and mould plate comprises described in polylith die unit 17 that die unit is uniformly distributed ringwise, on described top board, lower platen, be provided with the bolt of fixed mold plate, the top board of described extrusion die, lower platen are all fixed in frame, and two adjacent die units are large outer little cavity 18 in forming one.
Described in each, on extrusion roll shaft, be socketed with two for the dustproof palace RunddichtringO 21 of bearing.Equal two jackscrews 22 on palace type sealing device described in each, jackscrew further holds out against palace RunddichtringO, and sealing effectiveness is better.
The operation principle of brown coal extrusion dehydration forming machine:
When brown coal enter after hopper, main shaft turns clockwise under the drive of belt pulley together with terminal pad, two groups of compression rollers are followed terminal pad and are rotated together, while is due to principle self the passive rotation again of eccentric shaft, the fallen brown coal of brown coal hopper are peritropous mould intraplate compression under the effect of centrifugal force, the squeezed pressure roller of brown coal little by little squeezes in the cavity in Die and mould plate, because large outside, cavity the inside is little, so it is increasing that squeeze pressure needs, brown coal will be squeezed into piece, the brown coal that are squeezed into piece will slowly be extruded by cavity, through brown coal discharge bucket, be transferred out.
