Abstract
The utility model relates to the improvement on a flat air flow crusher, particularly a ceramic liner of the crusher cavity. The utility model is characterized in that adjacent splicing ceramic blocks are formed into concave convex lap joint or oblique joint, a through hole which is admissible for a bolt head is arranged in the direction of the thickness of each ceramic block, and the ceramic blocks are fixed to the inner wall of the cavity by the connection of screws. Compared with the binding joint of the prior art, the utility model greatly improves the binding fastness of the ceramic blocks of the liner and the crushing cavity and ensures the non-dropping of the ceramic blocks. The improved flat air flow crusher is especially suitable for the crusher which uses gaseous steam as an air source.
Description
Technical field
Utility model is about the improvement to flat airslide disintegrating mill, relates in particular to the crusher cavity ceramic lined.
Background technology
The flat airslide disintegrating mill of ultra-fine grinding is pulverized for improving the wearability of cavity, and contaminated material not contains the oxygen aluminium oxide at 99 porcelain for example more than 95% at metal crushing chamber inside liner usually.Yet for the crushing chamber diameter greatly as diameter more than 500mm or bigger, because the restriction of lining porcelain production technology, be difficult to make integrally-built porcelain liner, so people propose to adopt piecemeal assembly unit lining, with the bonding metallic cavity inner surface that is assembled in of ceramic block that decomposes, each adjacent ceramic piece is straight mouthful adjacency by binding agent.This kind passes through the directly time flat airslide disintegrating mill of mouthful adjacency, bonding lining ceramic block, is used for the compressed air gas source pulverizing and still can uses, yet be the raising grindability, needs for example 10kg/cm of employing superheated steam
2Superheated steam do to be pulverized source of the gas, pulverize cavity temperature higher as up to 350 ℃ about.In such hot environment, because pottery is different with the coefficient of expansion of metal, and binding agent itself expands, the ceramic block that very easily causes boning becomes flexible and comes off, and the adjacent ceramic piece flushes for straight mouthful, does not have overlap joint power mutually, and the overlap joint globality is poor, as long as a loose or dislocation is arranged, will cause all coming off gradually.Even employing high-temperature agglomerant, effect are still undesirable, cause coming off of ceramic block equally easily, therefore straight mouthful of adjacency of this ceramic block, bonding lining are not suitable for the pulverizing that superheated steam is made source of the gas.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of ceramic lined bonding strength height is provided, the flat airslide disintegrating mill of lined ceramics piece difficult drop-off in hot environment.
The utility model purpose realizes, main improvement is the liner porcelain pottery lining piece that will decompose, the adjacent straight mouth flushes and changes concavo-convex overlap joint or scarf joint structure into, to improve the mutual overlap joint globality of lining, and have the through hole that can hold bolt head at each ceramic block thickness direction, and with screw ceramic block is fixed on the metal shell inwall, reach the fastness that is connected that strengthens ceramic block and metallic matrix, effectively overcome and separated the defective that comes off, made in hot environment, still can not come off.Specifically, the flat airslide disintegrating mill of utility model, comprise endless metal crushing chamber and liner splicing ceramic block, it is characterized in that said adjacent ceramic piece is in abutting connection with being concavo-convex overlap joint or scarf joint, each ceramic block thickness direction has the through hole that holds bolt head, connects by screw ceramic block is fixed on the cavity inner wall.
The said screw of utility model, a kind of employing sunk screw that is preferably, bolt head is less, and ceramic pit is little, and is less to the ceramic block loss of strength.Be the lining make things convenient for ceramic block and further improve switching performance, a kind of better mode of utility model is, in ceramic block and ceramic block adjacent side and and the metallic matrix joint face, also executed binding agent.
The utility model airslide disintegrating mill, the lining ceramic block is owing to adopt screw fixing and adjacency overlap joint concavo-convex overlap joint of good integrity or scarf joint, improved the combine fastness of lining ceramic block greatly, can guarantee that ceramic block does not come off, be particularly useful for adopting superheated steam to make the pulverizer of source of the gas with crushing chamber.
Further specify utility model below in conjunction with a specific embodiment.
Description of drawings
Fig. 1 is a utility model airslide disintegrating mill structural representation.
Fig. 2,3,4 is respectively ceramic block and connects and the abutment structure schematic diagram.
The specific embodiment
Embodiment: referring to Fig. 1,2, the flat airslide disintegrating mill of utility model, comprise that diameter reaches the stainless steel metal pulverizing cavity 1 of 1070mm, liner 99% aluminium oxide ceramics piece 2, each adjacent ceramic piece adopts scarf joint in abutting connection with seam 4, each ceramic block thickness direction has the connecting through hole that holds bolt head, is fixed in the crushing chamber inner surface by sunk screw 5.The ceramic block adjacent side reaches with the metallic matrix joint face binding agent 3.
Utility model ceramic block, adjacent surface can also adopt as Fig. 3,4 tenon socket or ledge structure.
Claims (3)
1, a kind of improved flat airslide disintegrating mill, comprise endless metal crushing chamber and liner splicing ceramic block, it is characterized in that said adjacent ceramic piece is in abutting connection with being concavo-convex overlap joint or scarf joint, each ceramic block thickness direction has the through hole that holds bolt head, connects by screw ceramic block is fixed on cavity inner wall.
2, according to the described flat airslide disintegrating mill of claim 1, it is characterized in that between said ceramic block and cavity and/or between ceramic block adhesive layer being arranged.
3,, it is characterized in that said screw is a sunk screw according to claim 1 or 2 described flat airslide disintegrating mills.
