Abstract

The utility model relates to a two-stage vacuum extruder for bricks and tiles, which belongs to the technical field of manufacturing bricks and tiles mechanical equipment, and is mainly used for producing hollow bricks and plane tiles. The upper stage of the utility model adopts a single reamer axis to drive a spiral reamer arranged on the single reamer axis, and the matching work with a clay pressing plate can convey clay materials identical with a double spiral reamer; the upper stage can save power by 30 %; the upper and the lower reamer axes are both supported at the end near a shaft coupling, so that the sealing performance of the whole machine can be increased, and the power of a vacuum pump can be saved by 20 %.

Description

A kind of two-stage vacuum brick and tile extruding machine

The utility model belongs to brick machinery and equipment and makes the field.

Prior art in the utility model prior art field is: the structure of the two-stage vacuum brick and tile extruding machine of Chu Shouing is rotated in opposite directions for up and down two-stage eclipsed form and upper level adopt two mangler shafts to drag screw reamer mounted thereto respectively in the market, support and seal at the two ends of axle, its weak point is: the one, and upper level takes two mangler shafts to drag respectively that screw reamer mounted thereto rotates in opposite directions thereby power consumption is big; Two is that two mangler shafts rotate in opposite directions, send the friction between pug to increase the power consumption that has further strengthened machine between two screw reamers; The 3rd, the two ends of two mangler shafts of upper level all need seal, and have strengthened the difficulty of sealing, and sealing property is difficult to guarantee that the vavuum pump power attenuation is big.

Purpose of design of the present utility model is: avoid the deficiencies in the prior art part, two-stage vacuum brick and tile extruding machine is designed to a kind of power, two-stage vacuum brick and tile extruding machine that vacuum is high saved.

Design of the present utility model is: structurally upper level adopts the simple lay cutter shaft to drag the soil compressing plate cooperating of installing on a screw reamer mounted thereto and the soil compressing plate axle, can carry the pug of equal number equally; Only higher level, subordinate mangler shaft is separately supported simultaneously, improved the sealing property of two-stage up and down, reduced the power attenuation of vavuum pump at a end near shaft coupling.

The utility model compared with prior art, the one, two mangler shafts that the upper level of two-stage vacuum brick and tile extruding machine is rotated in opposite directions are designed to the simple lay cutter shaft, and playing the effect of double helix reamer equally with the soil compressing plate cooperating mounted thereto that the soil compressing plate axle drags, the upper level motor can be saved power 30%; Because up and down the mangler shaft of two-stage all only supports at the end near shaft coupling, thereby the sealing property of complete machine improves greatly, and vacuum also improves thereupon, can save the power 20% of vavuum pump.

Fig. 1 is the front view of a kind of embodiment of the present utility model.

Fig. 2 is the vertical view of a kind of embodiment of the present utility model.

Embodiment:

In conjunction with Fig. 1, Fig. 2 the utility model is described in further detail.

Be fixed in the outlet of subordinate's mud cylinder 2 left ends with reference to Fig. 1, Fig. 2 head 1 of the present utility model, subordinate's screw reamer 4 is fixed on subordinate's mangler shaft 3, subordinate's mangler shaft 3 by being positioned at subordinate mud cylinder 2 outsides bearing block forming by bearing 24,25 and be installed on subordinate's mud cylinder 2 by another bearing block that bearing 23 is formed, another bearing block that mud cylinder 2 and bearing 23 are formed all is positioned on the fuselage 21; Vacuum chamber 7 is connected as a single entity by screw 5 and subordinate's material receiving box 6, wireway 8 is installed in the upper end of vacuum chamber 7 and is communicated with vacuum chamber 7, resistance mud ring 9 is positioned at vacuum chamber 7 and is connected with higher level's discharging opening 10 usefulness screws, higher level's discharging opening 10 links to each other with higher level's mud cylinder 12, higher level's screw reamer 13 is installed on higher level's mangler shaft 11, higher level's mangler shaft 11 by be positioned at higher level's mud cylinder 12 outsides by bearing 16,17 bearing block forming and another bearing block of forming by bearing 19 and be positioned at higher level's mud cylinder 12, higher level's mud cylinder 12 with by bearing 16, seal by sealing ring 15 between 17 bearing blocks of forming, soil compressing plate axle 27 by be positioned at hopper 14 outsides by bearing 28,30 bearing blocks of forming separately and be positioned at hopper 14, gear 18,26 gear-boxes of forming and higher level's mud cylinder 12 and all be positioned on the fuselage 21 by another bearing block that bearing 19 is formed.

During work, at first start vavuum pump, by the wireway 8 continuous air of extracting out in the vacuum chamber 7, starter motor then, after reductor slows down, use grade shaft coupling 20 and drive 11 rotations of higher level's mangler shaft, pug enters in higher level's mud cylinder 12 by hopper 14, higher level's mangler shaft 11 will drive the driving gear 18 and higher level's mangler shaft 11 fixed connections of soil compressing plate axle 27 rotations by flat key, itself and higher level's mangler shaft 11 are rotated in opposite directions, with the driven gear 26 drive soil compressing plate axles 27 of driving wheel 18 engagements and soil compressing plate 29 rotations of installing on it, pug is pressed into the helicoid of higher level's screw reamer 13, by higher level's screw reamer 13 pug is pushed ahead through resistance mud ring 9 and to enter in the vacuum chamber 7, become closely knit pug behind the vacuumizing and fall into the subordinate's material receiving box 6 that is positioned at vacuum chamber 7 bottoms, continued to push ahead by subordinate's reamer 4, extrude by head 1, form the base bar of definite shape.The replacing of head 1 can realize producing the purpose of hollow brick or plane tile.
