Abstract

The utility model relates to a porous ceramic body. Granular ceramic base materials and proper amount of organic binding agent are evenly mixed, stirred and moulded into a desired shape. The surfaces of the granular ceramic base materials are fritted into the porous ceramic body through drying and high-temperature sintering to obtain the purposes that the utility model has excellent structural strength, low cost, permeability and filterability.

Description

Porous ceramic body

The utility model relates to the ceramic technology field, refers in particular to a kind of porous ceramic body.

Ceramic body is widely used in agricultural and plants the filter material of the medium of planting, agricultural fertilizer, pesticide slow-release carrier, fishery cultivating water quality, cultures the filter material that the filter material of make the bed at the bottom of the pond material, general family, industry, off gas treatment and catalyst carrier and metal casting are used.The method for making of ceramic body is divided into three kinds substantially:

First kind is the method for making of traditional monomer-type ceramic body, make imporous ceramic particle body by ceramic base material with weight or other modes, it supplies the usefulness of planting or filtering of planting of agricultural fishery mostly, because this its structure of monomer-type ceramic body is not had a porousness, and its whole surface area is less, cause permeability reduction, filter effect is relatively poor etc., so moisture and air can't be kept somewhere on ceramic particle, farming is planted and the beneficial bacterium of the decomposition fertilizer of fishery grows up and can't provide the moisture of suitable foot and air to supply with to help, value and effect in the use are relatively poor, cause inconvenience and puzzlement in the use.

Second kind is the ceramic body method for making that is extruded into pattern, and it mainly is that ceramic base material mixing tackiness agent is formed a mixture, and with the honeycomb structure of this mixture via the vertical section net, extruding is the ceramic body of strip.The ceramic particle body of its more above-mentioned traditional monomer-type has preferable perviousness and filterableness, can keep more water and air, uses the situation that goes up easy generation breakage but this kind is extruded into the ceramic body of pattern, so the efficient of using is lower.

The third is the porous ceramic bodies method for making of soaking paste formation type, it is with the cavernous body dipping ceramic mud of foaming, and then after extruding, remove unnecessary ceramic mud, then carry out drying, and remove this polymer sponge body with high temperature or chemical agent, make the porous ceramic body of tool, the effect of its use is better than above-mentioned two kinds, but, cause integral intensity relatively poor, so easily produce breakage when using because that its hole distributes is more closely knit, and because hole is too trickle, the situation that Yi Sheng blocks cause work-ing life shorter, and cost is comparatively high.

The purpose of this utility model is to provide a kind of porous ceramic body.With granular ceramic base material and an amount of organic binder bond mixing and stirring, be molded into required shape, drying, again through high temperature sintering, make the surface clinkering of particulate state ceramic base material become porous ceramic body, reach and have better structural strength and with low cost, and have the purpose of perviousness and filterableness.The purpose of this utility model is achieved in that

A kind of porous ceramic body cooperates the porous ceramic body with careful open hole slot that sintering forms behind the organic binder bond mould-formings by most ceramic particles.

Major advantage of the present utility model is: have better structural strength and with low cost, and have the effect of perviousness and filterableness.

Below in conjunction with preferred embodiment and accompanying drawing the utility model is further specified:

Fig. 1 is a product schematic perspective view of the present utility model;

Fig. 2 is a product diagrammatic cross-section of the present utility model;

Fig. 3 is the schematic perspective view of embodiment of the present utility model;

Consult Fig. 1-Fig. 2, ceramic body 2 of the present utility model is that most ceramic particles 1 add organic binder bond 4 bonding mould-formings, porous ceramic body 2 through sintering formation with careful open hole slot 3, it has preferable structural strength, 1 of each particle has bigger open hole slot 3 continuously, ceramic body 2 has good penetration, filters and give birth to and adsorptivity, whole surface-area is bigger, exactly the moisture of enough maintenance appropriateness and air are in ceramic product 2, the beneficial bacteria growing space of decomposing fertilizer is provided, is applicable to agricultural cultivation and various Filters.

Embodiment 2

Consult Fig. 3, porous ceramic body 2 of the present utility model can also be made rectangular parallelepiped or other required shapes, only need change mould and just can realize.Have handling ease, with low cost, advantage such as sturdy and durable.

Claims

1, a kind of porous ceramic body is characterized in that the structure of this ceramic body, the porous ceramic body with careful open hole slot that cooperates organic binder bond mould-forming sintering to form by most ceramic particles.

2, porous ceramic body as claimed in claim 1 is characterized in that the shape of this ceramic body comprises right cylinder, rectangular parallelepiped or required shape.
