Abstract
The present invention discloses a carbon crystal compound micropore ceramic filter element and a method for producing the same, the principal ingredients of the carbon crystal compound micropore ceramic filter element are bergmeal and charcoal powder, the filter element is moulded by casting or compacting after other materials such as light calcium carbonate and kaolin are added and mixed, the shape of the finished product of the carbon crystal compound micropore ceramic filter element sintered under the reducing atmosphere can be tubular, clintheriform, hemispherical and so on,.This kind of micropore ceramic filter element is mainly used for water-treating equipment or other filter device; and the product has various functions of filtrating, adsorbing and controlling bacterial reproduction and so on.
Description
Technical field
The present invention relates to the micropore ceramic filter element technical field; Especially relate to and a kind ofly possess filtration simultaneously, adsorb and suppress vegetative micropore ceramic filter element and preparation method thereof.
Background technology
Micropore ceramic filter element is a filtering material commonly used in the filter plant, but, this micropore ceramic filter element only has filtering function, can not remove the look in institute's medium, smelly, flavor, do not suppress vegetative function yet, filter plant is had remove the function of look, smelly, flavor, can only in filter plant, install active carbon and silver ion additional, so its application has been subjected to certain restriction.
Summary of the invention
The present invention is directed to a kind of that this state of the art provides and to remove look, smelly, flavor again by filtering particle shape impurity, also have the vegetative carbon crystal compound micropore ceramic filter element of inhibition simultaneously.
The technical scheme that the present invention addresses the above problem is:
This carbon crystal compound micropore ceramic filter element is a main component with diatomite and powdered carbon, and preparation process is that materials such as diatomite, precipitated calcium carbonate, kaolin, active carbon are mixed according to certain ratio, stirs after slip casting or compression moulding obtain semi-finished product.These semi-finished product are inserted in the container after drying, evenly cover with coal dust or powdered carbon, with cover plate this container are covered, and form an airtight space.Be in because of semi-finished product in the reducing atmosphere of a sealing, the active carbon in the semi-finished product in high temperature because of can contacting with oxygen and can burn, thereby make carbon crystal compound micropore ceramic.
Key technology is these goods to be inserted in the airtight container burn till in the carbon crystal compound micropore ceramic filter element preparation process of the present invention.Solution describes in detail in the specific embodiment.
Used container must be that resistant to elevated temperatures refractory material is made when carbon crystal compound micropore ceramic filter element of the present invention was fired, and it is high that this container material density is wanted, and gas permeability is low.
Must fill coal dust or powdered carbon in container when carbon crystal compound micropore ceramic filter element of the present invention is fired, and its fineness to reach more than 40 orders.When covering vessel port with cover plate, the vessel port edge must carry out adhering and sealing with resistant to elevated temperatures refractory material furnishing pasty state.
When will having bacteria resistance function, carbon crystal compound micropore ceramic filter element of the present invention need add a certain amount of silver ion.
Temperature was 900 ℃-1700 ℃ according to the selected firing range of the proportioning of material when carbon crystal compound micropore ceramic filter element of the present invention was fired
Description of drawings
Fig. 1: carbon crystal compound micropore ceramic filter element technological process of production figure of the present invention;
Fig. 2: the semi-finished product container schematic diagram of packing into.
The specific embodiment
Below in conjunction with concrete accompanying drawing carbon crystal compound micropore ceramic filter element of the present invention is described in detail, but is to be understood that the description does not here constitute limiting the scope of the invention.
The composition of carbon crystal compound micropore ceramic filter element of the present invention is: diatomite, precipitated calcium carbonate, kaolin, active carbon, silver ion etc., main component wherein: diatomite weight accounts for 20%-98%, active carbon weight accounts for 1-30%, silver ion adds in right amount according to antibacterial intensity, and other materials is done flexible adjustment according to desired micropore size size and volume to weight ratio.
Above-mentioned raw materials is crushed to 200-800 purpose powder respectively, selects 200-400 purpose powder when needing low filtering accuracy for use, select 400-800 purpose powder in the time of need be than high filtering precision for use.After having prepared above-mentioned raw materials, weigh, in proportion above-mentioned material is mixed according to desired micropore size, and through stirring; If injection forming, above-mentioned material is added entry and medium is made mud, according to needed shape, inject different gypsum molds, take out back to be formed, and standby after drying.If compression moulding adds a certain amount of glue with above-mentioned material, and after fully stirring,, select different moulds, use press compression moulding according to needed shape, and standby after drying.
The method key of carbon crystal compound micropore ceramic filter element preparation of the present invention is: when packing semi-finished product into container, that semi-finished product and air are isolated.Concrete preparation process is: the base substrate of above-mentioned slip casting or compression moulding is stand-by after drying, get a high-temperature resistant container, and add other materials furnishing pasty state with kaolin, smear this appearance equably with hairbrush
Above appearance and the blank cover (4).Because of this material can form air-locked film behind high temperature, increase the air-tightness of this container; Spread coal dust or powdered carbon (2) equably at the container lower curtate, THICKNESS CONTROL is at 2-3cm.Stand-by base substrate (3) is put into this container, and base substrate is 2-3cm from container inner wall distance, with coal dust or powdered carbon (2) be filled into equably base substrate (3) around, base substrate (3) is covered fully.The height of filler is concordant with vessel port; The colloid made from ceramic material is smeared the edge of vessel port equably then.It is bonding that cover plate (4) is covered vessel port; Pack into and fire according to different temperature in the high temperature kiln.Because of a spot of air is still arranged in the airtight container, when high-temperature calcination, the coal dust of filling or powdered carbon are with a spot of air contact in the container and produce burning, extinguish after waiting to run out of the oxygen in the container.The consumption of filler is the 1-2% of whole filler total amount.Wait to fire and finish and fully after the cooling, open furnace door, take out container, open cover plate, take out and fire the goods of finishing.After handling, polishing promptly gets carbon crystal compound micropore ceramic filter element.
