Abstract
The invention discloses a composite ceramic dewatering element for a paper making machine. The composite ceramic dewatering element comprises an alumina ceramic layer, a high-quality ceramic layer and a ceramic base, wherein one face of the alumina ceramic layer is connected with the high-quality ceramic layer through high-temperature combustion, the other face of the alumina ceramic layer is connected with the ceramic base through a fixing groove in a bonded and assembled mode. An installation groove connected with an external device is formed in the bottom of the ceramic base. The high-quality ceramic layer is made of silicon nitride ceramic or silicon carbide ceramic. By means of the method, production cost can be greatly reduced while it is ensured that the ceramic dewatering element has the advantages of being high in abrasion resistance and high in quality; the composite ceramic dewatering element has the high cost-performance ratio.

In a preferred embodiment of the present invention, the temperature of described high-temperature firing is 180 DEG C, makes to fire between aluminium oxide ceramics layer and high-quality ceramic layer the comparatively firm of connection.
In a preferred embodiment of the present invention, institute is according to mass fraction proportioning: described aluminium oxide ceramics layer is 60 parts, and described high-quality ceramic layer is 40 parts, is ensureing under the high-quality prerequisite of ceramic dewatering element, by the maximum of the amplitude control of cost.
In a preferred embodiment of the present invention, described external equipment is paper machine shaping box, dewatering box, scrape any one of water tank, vacuum tank, flat rack and suction box, and the equipment scope of its utilization is comparatively extensive.
In a preferred embodiment of the present invention, described base of ceramic adopts carbon fibre reinforced composite, and ceramic dewatering element is possessed has intensity at high temperature good, and high temperature form stable can anti-crack propagation, feature that can damping.
The invention has the beneficial effects as follows: more than the present invention can be applicable to speed of a motor vehicle 1500m/min, paper web, more than 6 meters, is disturbed Qu Qiangdu MPa750, heat-resisting vibratility K600, and also ABRASION RESISTANCE is better, and more than 10 years, ensured its high-quality requirement service life; Replace a part of silicon nitride with the lower aluminium oxide of price simultaneously, reduced the production cost of 19 times.
Brief description of the drawings
Fig. 1 is the structural scheme of mechanism of the present invention in a preferred embodiment;
In figure, each assembly and Reference numeral are respectively: 1, high-quality ceramic layer, 2, aluminium oxide ceramics layer, 3, base of ceramic.
Detailed description of the invention
The present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Please refer to Fig. 1 in an embodiment of the present invention, a kind of paper machine composite ceramic dewatering element, comprise: aluminium oxide ceramics layer 2, high-quality ceramic layer 1 and base of ceramic 3, the one side of described aluminium oxide ceramics layer 2 is connected by high-temperature firing with described high-quality ceramic layer 1, the another side of described aluminium oxide ceramics layer 2 glues together assembly connection by holddown groove and described base of ceramic 3, the bottom of described base of ceramic 3 is provided with the mounting groove being connected with external device, and described high-quality ceramic layer 1 is silicon nitride ceramics or silicon carbide ceramics.
Wherein, according to mass fraction proportioning: described aluminium oxide ceramics layer 2 is 60 parts, and described high-quality ceramic layer 1 is 40 parts, after tested, described ratio can ensure ceramic dewatering element possess have better quality, under the prerequisite of stronger anti-wear performance, by cost to minimum.
The temperature of described high-temperature firing is 180 DEG C, and because the adhesion strength of silicon nitride reaches the strongest in 180 DEG C, therefore the temperature of high-temperature firing is preferably 180 DEG C, thereby improves the firmness connecting between high-quality ceramic layer 1 and aluminium oxide ceramics layer 2.
Described external equipment is paper machine shaping box, dewatering box, scrape any one of water tank, vacuum tank, flat rack and suction box, and as can be seen here, the equipment scope that the present invention can use is wider, can promote the development of paper industry.
Described base of ceramic 3 adopts carbon fibre reinforced composite, and ceramic dewatering element is possessed has intensity at high temperature good, and high temperature form stable can anti-crack propagation, feature that can damping.
Be different from prior art, the present invention has disclosed a kind of paper machine composite ceramic dewatering element, by high-quality ceramic powders and the heavy rear compacting of aluminium oxide ceramics powder meter, carry out high-temperature firing connection by the high temperature of 180 DEG C again, then gained semi-finished product are refined to processing, then the semi-finished product after fine grinding are glued together to assembly connection by the base of ceramic 3 of holddown groove and carbon fibre reinforced composite, finally entirety is refined and reach 0.1mm to surface roughness and complete processing, and in the prior art, the domestic aluminium oxide ceramics powder that all adopts is manufactured ceramic dewatering element, but its quality is reported to the leadship after accomplishing a task, ABRASION RESISTANCE is also reported to the leadship after accomplishing a task, and adopt silicon nitride ceramic powder or silicon carbide ceramics powder to manufacture ceramic dewatering element abroad, but its production cost costliness, the mode that the present invention adopts the high-quality ceramic layer 1 of making at silicon nitride ceramic powder or silicon carbide ceramics powder to be connected with levels high-temperature firing with aluminium oxide ceramics layer 2, more than not only can ensureing that ceramic dewatering element is applicable to speed of a motor vehicle 1500m/min, paper web is more than 6 meters, disturb Qu Qiangdu MPa750, heat-resisting vibratility K600, possess and have anti-wear performance strong, the high feature of quality, can also make production cost reduce by 19 times, possess and have good cost performance.
