Abstract

The utility model relates to a vacuum stiff brick extruding machine, which comprises an extruding part. The extruding part comprises a reamer and a machine port seat. A mold seat and a machine port which is connected with the mold seat are arranged in the machine port seat. The utility model has the different proposals that the front slope degree of the inner hole of the mold seat is bigger than the back slope degree; the front length is smaller than 1/2 length of the mold seat. When the brick blank passes through the mold seat, the brick blank enters from the front of the mold seat, and the brick blank is extruded by a short distance fast speed extrusion in the front of the mold seat firstly. Then the brick blank is extruded by a longer distance slow extrusion. The extruding mode is adapted to the characteristic of the coal gangue and the pressure in the blank is uniform, and thus the quality of the brick blank can be ensured.

Description

Vacuum is moulded extruder firmly

The utility model is that a kind of vacuum is moulded extruder firmly, belongs to a kind of brickmaking mechanical.

Be the minimizing environmental pollution in China, and refuse made full use of that many collieries utilize making coal gangue brick.The mould seat of brick extruding part is one of key of green brick forming in the extruder.Its anterior gradient of mould seat endoporus in the existing extruder is less and distance is longer, and its rear portion gradient is big and distance is less.The phenomenon of face crack often appears in the gangue adobe of using the extruder of this structure to make, thereby influences product quality.

The purpose of this utility model is: design a kind of gangue, flyash equal industrial residue of utilizing and mould extruder firmly for raw material, vacuum that the quality of production is good.

The utility model is to realize by the improvement to the extruding part of adobe.Same as the prior art, comprise reamer and machine mouth seat in the extruding part of the present utility model, the machine mouth that the mould seat is arranged in the machine mouth seat and be attached thereto; Different is, the gradient of mould seat endoporus of the present utility model front portion is greater than the gradient at rear portion, and its anterior length is less than 1/2 of mould seat length.

When adobe material during through mould seat of the present utility model, enter by the place ahead of mould seat, and carry out more short-range extruding rapidly by the front portion of mould seat earlier, and then through the slow extruding of longer distance.This fashion of extrusion comparatively adapts to the characteristics of gangue, makes the inner pressurized of blank even, can guarantee unfired brick quality.

The anterior endoporus gradient of mould seat accounts for 1/5 of mould seat length greater than 1: 1.05 length.For improving service life, reduce production costs, in the utility model machine mouth wearing layer can be installed, wearing layer is by being installed in the machine mouth by the end face of mould seat and the pressure cap of machine mouth port.

Before this, the machine mouth of extruder is a version of being made one by high-abrasive material, because machine notch portion serious wear, thereby will change the machine mouth is whole in use for some time, thereby wastes more.Change the machine notch portion into wearing layer that said structure only need change wherein and get final product, and also can reduce requirement like this machine gate material, thus the cost and the production cost of reduction equipment itself.

Above-mentioned wearing layer can be by being structure as a whole, and also can is installed in the four sides of mould seat endoporus respectively and be formed by four wearing plates, grinds the processing of layer so that make and install all more or less freely.

In addition, also wear-resisting circle should be installed at the rear port place of machine mouth, it is installed between pressure cap and the wearing layer.

Equally, wear-resisting circle also can be made up of four wear ribs.Like this, each wear rib prolongs the service time of each wear rib in use for some time by the replaceable rubbing surface of upset.

In view of the foregoing, wear rib of the present utility model preferably can be adjusted, and is used to adjust the position of wear rib inner surface as the inner adjustment bolt that contacts with wear rib is arranged in the pressure cap side.

Wear rib also can be fixed by passing the puller bolt that the pressure cap rear end contacts with wear rib.

In addition, the reamer of the utility model employing is that anterior pitch is big, the less screw reamer of rear portion pitch.The pitch of reamer can segmentation changes, also can reamer by continuous variation.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the structure chart of the extruding part of the utility model embodiment;

Fig. 2 is the structure chart of reamer;

Fig. 3 is the cutaway view of machine mouth seat rearview;

Wherein, 1-inclined bearing axle, 2-air bleeding valve, 3-pneumatic clutch, the 4-belt pulley set, 5-reduction box, 6-shaft coupling, 7-differential material toggling mechanism, the 8-spindle assemblies, 9-connecting box, 10-hopper, 11-machine mouth seat, the 12-screw reamer, 13-mould seat, 14-wearing plate, 15-adjusts bolt, 16-pressure cap, 17-puller bolt, the 18-wear rib, 19-bolt, 20-machine mouth.

Present embodiment is by mixing part, extruding part and cut base and partly form, wherein the mixing part, cut the base part form same as the prior art, repeat no more here.As shown in the figure, the extruding part of present embodiment comprises base, on the base by be equipped with successively behind the forward direction inclined bearing axle 1, air bleeding valve 2, pneumatic clutch 3, belt pulley set 4, reduction box 5, shaft coupling 6, differential material toggling mechanism 7, spindle assemblies 8, with connecting box 9, hopper 10, machine mouth seat 11 that the mixing part joins, screw reamer 12 is arranged in hopper 10.Screw reamer 12 is the varying pitch form, and its pitch diminishes from front to back continuously.The machine mouth seat 11 of present embodiment is made up of mould seat 13 that is connected and machine mouth 20.Wherein the endoporus of mould seat 13 from front to back its gradient gradually change: its anterior gradient is greater than the gradient at rear portion, and anterior endoporus gradient accounts for 1/5 of mould seat 13 length greater than 1: 1.05 length.Rear at the machine mouth 20 of present embodiment is equipped with wear-resisting circle, and wear-resisting circle is made up of four wear ribs 18, and they are fixing by the pressure cap 16 at its rear, and pressure cap 16 is to be connected with machine mouth 20 by the bolt 19 that passes wherein.Have on the rear end face of pressure cap 16 and pass the puller bolt 17 that pressure cap 16 contacts with wear rib 18, there is the adjustment bolt 15 of the contacts side surfaces of passing pressure cap 16 and wear rib 18 side of pressure cap 16.On the inner surface of machine mouth 20 between wear rib 18 and the mould seat 13 wearing layer is installed, wearing layer is fixed by end face and wear rib by the mould seat.Wearing layer is made up of four wearing plates 14.
