Abstract
The utility model relates to an use hot briquetting machine of wood fibre granule as raw materials, it has interior cold type screw axis, radiation shield and adapter with the difference of ordinary this type of extruder, is done the cavity in the screw axis, installs interior cold tube in the cavity, because the cooling effect of circulating water, has solved the screw axis of conventional extruder and antifriction bearing's temperature rise and the problem that life is low, can be corresponding the extrusion speed of improvement screw axis, increase output.
Description
The utility model is a kind of hot-forming machinery, and particularly a kind of is the heat pressing forming machines of raw material with the lignocellulosic particle.
Heat pressing forming machines belongs to a kind of HTHP forming machine, and it is to make material be extruded moulding and charing through heating again by producing strong friction between the helical axis of rotation and the material and pushing.All there is following defective in several homemade these class make-up machines at present: (1) helical axis and material be friction and extruding sharply, the high temperature that produces makes the particle temperature at helical axis friction position surpass the crossing temperature of material sometimes and very easily weares and teares, reduce the service life of helical axis, improved cost; (2), thereby cause the reasonable clearance between interior overcoat of bearing and the rolling element to diminish so that damage too early because the high temperature at extrusion friction position causes each the rolling bearing temperature rise that is used to support too high through overheated conduction.
The purpose of this utility model provides the granule materials heat pressing forming machines that inner-cooled helical axis and collet are arranged of a kind of helical axis and bearing long service life.
The utility model is to realize like this, it is mainly by frame, motor, driving mechanism, molding seat, supporting base, helical axis, tapered sleeve, electric calorifie installation, forming tube, compositions such as hopper, it also comprises the inner-cooled helical axis, be loaded in the endoporus of be shaped seat and supporting base, cavity along the held recirculated water that the end sealing parallel with the helical axis axis arranged on the helical axis axis, in helical axis extrusion head place sealing and at the cavity length of helical axis afterbody opening less than helical axis length, making to have the apopore more than two or two that communicates with cavity on the helical axis, the cylindrical circular inner cool tube of hollow is positioned in the cavity by guided bearing, the axis of inner cool tube is parallel with the axis of cavity, the passage that flows for recirculated water is arranged between inner cool tube outer peripheral face and helical axis cavity inner wall, the inner cool tube end that is positioned at the helical axis afterbody communicates with water system, be set with collet at the helical axis middle part, collet is fixed between the end face of be shaped seat and supporting base, collect cavity is arranged in the collet, collect cavity and the water inlet that is positioned at the collet both sides, the afterbody that delivery port communicates respectively at helical axis is set with adapter, it is by ringwise cover and be fixed in the pipe joint that puts and form, do to have annular radial groove, the groove that communicates with the pipe joint hole to face the helical axis apopore and communicate along the cover inwall with apopore.Water inlet on the collet and delivery port lay respectively on the collet outer peripheral face on 180 ° position.Be fixed with the arresting lever 6 that prevents to overlap rotation on adapter, this heat pressing forming machines also has water pump, the water tank of using for recirculated water.
Because in working order; cavity in the helical axis, the cavity in the collet all have mobile recirculated water ceaselessly to flow; thereby in crush-zone because fricative high temperature; just ceaselessly take away by the water in the cavity; thereby the temperature rise of the rolling bearing of the temperature rise of helical axis and supporting role is controlled effectively; improve their service life greatly, also reduced the downtime of changing helical axis, bearing, improved operating efficiency.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an adapter and the schematic diagram that cooperates of helical axis afterbody.
As shown in Figure 1, helical axis be bearing in supporting base 7 by bearing and the seat 15 that is shaped in endoporus in, on helical axis 14 axis, make earlier a cavity 16 that runs through helical axis 14 axis, again in the end of the extrusion head 18 of band tapering with the end sealing of cavity 16, make cavity 16 become an end sealed hollow.With the outer peripheral face of the tail end of extrusion head 18 ends helical axis 14 far away as far as possible on can make one or porous apopore 27, apopore 27 communicates with cavity 16.Inner cool tube 8 is a hollow circular tube, and is positioned in the cavity 16 by guided bearing 9, can make and the coincidence parallel with cavity 16 axis of inner cool tube 8 axis usually.The cross-sectional sizes of the diameter of inner cool tube 8 and cavity 16 should be according to the heat radiation situation, the flow of recirculated water, and guarantee should have between inner cool tube 8 and the cavity 16 enough passages 6 to decide for the recirculated water circulation.One end of inner cool tube 8 links to each other with water system.Collet 10 is annular, is set in helical axis 14 middle parts, and is contained between two end faces of be shaped seat 15 and supporting base 7, and collet 10 makes to have annular collect cavity 11, and the cross section of collect cavity 11 should be big as far as possible under the situation that structure allows.So that the heat that collet 10 can more effectively transmit the extruding position is taken away, doing respectively on the outer peripheral face of collet 10 has 12, one delivery ports 21 of a water inlet, and intake- outlet 12,21 communicates with collect cavity 11 respectively.The position of entery and delivery port 12,21 is suitable for to be distributed on the collet 10 on the position of the apopore 27 of 180 ° inherent helical axis 14 afterbodys of scope and is set with adapter 5, adapter 5 is by the cover 24 and the pipe joint 25 of annular, sealing ring 28 and arresting lever 4 are formed, make to have the annular radial groove 26 that holds recirculated water in the cover 24, the hole of pipe joint 25 communicates with groove 26, the position of groove 26 faces the apopore 27 of helical axis 14, and the other end that is fixed on the arresting lever 4 of cover on 24 is fixed on the correct position on the frame 1.
In this extruder when work, start water pump 21, motor 2, and under the effect of driving mechanism 3, helical axis 14 rotates, and enters in the alveolus of helical axis 14 state that is in extruding and moves forward at the material of hopper 13.When material entered tapered sleeve 17 and extrusion head 18, material was subjected to strong extruding, and entered in the shaping drum 19 by electric calorifie installation 20 heating and be extruded moulding, because strong extruding and fricative heat make the temperature rising of helical axis 14 and shaping drum 19.Under the effect of water pump 22, the water in the water tank 23 enter the inner chamber of inner cool tube 8 respectively and enter in the collect cavity 11 along the water inlet 12 of collet 10.Flow out the end of water along inner cool tube 8 from the inner cool tube 8 that is positioned at extrusion head 18 that enters in inner cool tube 8 inner chambers, then the apopore 27 of 14 tail ends flows out along passage 6 from helical axis, in the groove 26 to the cover 24 of adapter 5, flow in the water tank 23 from pipe joint 25 again.The water that enters in the collect cavity 11 of collet 10 flow in the water tank 23 along the delivery port 21 of collet 10.Therefore the problem of temperature rise of the helical axis 14 and the seat 15 that is shaped just can constantly be taken out of and be solved by recirculated water effectively.So the utility model increases substantially the service life of helical axis 14 and guarantees the unlikely early stage damage of each rolling bearing, thereby reduced cost, prolong service interval and because the effect of water-cooled cooling, just can improve the working speed of helical axis 14, the output of raising extruder.
