Description
Technical field
The present invention relates in a kind of hot melts production process the strainer used, particularly a kind of quick net exchanging plate filter sealing compensation automatically.
Background technology
In the production process to hot meltss such as PP, PE, hot melt adhesive and elastomericss, in hot melts, it is entrained with mechanical impurity unavoidably, does not filter out these mechanical impuritys, following process can be caused certain trouble, also can cause the defective problem of quality product simultaneously. Therefore, filter out mechanical impurity very necessary, generally adopt strainer to filter at outlet of extruder.
Traditional plate filter, the easy wear out failure of its wear ring, thus cause hot melts to leak, cause the accidents such as parking stopping production. The process changing wear ring in addition is also pretty troublesome.
Summary of the invention
It is an object of the invention to the quick net exchanging plate filter solving existing plate filter wear ring inefficacy easy to wear to provide a kind of, the sealing of the troublesome problem of screen replacing compensates automatically.
The technical scheme of the present invention is:
A kind of quick net exchanging plate filter sealing compensation automatically, comprise the suction flange and discharge flange that utilize fastening piece to be fixed as one, on being clipped between suction flange and discharge flange respectively, the spacing plate of lower rim, it is fixed on the electric heating panel outside suction flange and discharge flange, its special character is: be also provided with hydro-cylinder and seat board thereof, described seat board utilizes screw mandrel to be connected with described spacing plate, described suction flange, it is provided with, in the space that discharge flange and spacing plate three are formed, the reciprocal slip orifice plate being connected with described hydraulic cylinder bar, described reciprocal slip orifice plate be provided with two arranged side by side and with described enter, the hot melts of discharge flange enters, the groove that outlet is alternately corresponding, filter screen it is provided with and its bottom land is provided with matrix shape through hole in described groove, described enter, the contact surface of discharge flange and reciprocal slip orifice plate is respectively equipped with to enter around hot melts, the wear ring of outlet and pressure ring, described enter, the corresponding described wear ring position of discharge flange has offered stair-stepping annular cavity respectively, it is provided with elastic compensation ring in described annular cavity, and enter with hot melts, multiple communicating aperture it is respectively equipped with between outlet.
The quick net exchanging plate filter that above-mentioned sealing compensates automatically, the material of described wear ring is cast iron, copper alloy or impregnated graphite.
The quick net exchanging plate filter that above-mentioned sealing compensates automatically, the thickness of described elastic compensation ring is 1mm��4mm.
The invention has the beneficial effects as follows:
1, owing to having set up elastic compensation ring at wear ring place, elastic compensation ring place cavity is connected with hot melts import and export respectively by multiple communicating aperture, then hot melts pressure forces elastic compensation ring to be out of shape, thus the abrasion of wear ring under reciprocal slip orifice plate effect is compensated automatically, solve the problem of existing plate filter wear ring inefficacy easy to wear, extend its work-ing life, prevent filter leaks.
2, owing to the orifice plate that back and forth slides is connected with hydraulic cylinder bar, it moves back and forth under the effect of hydraulic cylinder bar and makes the groove being provided with filter screen arranged on it be exposed to outside, thus is convenient for changing filter screen, reaches the object of quick net exchanging.
3, safeguard simply, easily operate.
