Abstract
The utility model relates to a special ceramic wear resisting fan which is mainly characterized in that hole grooves are arranged on a front and a back side plates of a housing, a worm plate, the working faces of impeller vanes, an air inlet edge, and a back disk, unit special ceramic blocks are embedded and glued in the hole grooves, and a great amount of unit ceramic blocks form a complete special ceramic hard face, so that the wear resisting performance of the surface is enhanced. The utility model has the advantages of wear resistance and high-efficiency energy saving, and ceramic is not easy to fall off.
Description
Blower fan is one of Important Auxiliary equipment of industries such as electric power, metallurgy, building materials, also is the key equipment that adopts under various dedusting dust discharges or the material gas delivery occasion, and they directly influence safety and production and economical operation.Owing in the gas of being carried a large amount of solid particle or material are arranged, thereby cause the heavy wear of blower fan, influence the normal operation of unit, even cause the damage of facilities accident.The wearing and tearing that solve blower fan have multiple measure, China is at present main to adopt: abrasion-proof backing block is installed, welds turbulent muscle at wear-resistant place, is coated with wear-resistant paint, surface Hardening Treatment, built-up welding or spraying abrasion-proof alloy, surface paste wear-resistant ceramic or the like, the abrasionproof effect is all played in these measures to some extent, but all has certain narrow limitation.Ceramic abrasionproof method is pasted on the surface; it is a kind of anti-wearing method that external the eighties grows up; the early 1990s is imported China into; because the operating conditions of state's inner blower is abominable, adhesive technology is unstable or impact because of idol in the working medium has unusual hard thing, usually causes that local ceramic block fragmentation comes off; in case breach appears in place's ceramic plane; from then on the solid grain of working medium high speed can sharply wash away the metal below the ceramic layer, and ceramic veneer is started, and peels off.Therefore, the surface is pasted ceramic abrasionproof method and is still had very big defective, is restricted in the use.
The purpose of this utility model is the deficiency that exists at existing blower fan, proposes the wear-resisting blower fan of a kind of special cermacis simple in structure, safe and reliable, long service life.
The purpose of this utility model is to realize like this, easily grind the position at the inner snail plate of existing fan casing, front and back side plate, inlay at impeller blade working surface, leading edge, hub disk place and glued joint pottery, pottery is junior unit piece one by one, form a ceramic stiff dough, thereby increase the abrasive resistance on surface.On casing 1, process circular hole, the size in hole and unit ceramic block embedded part consistent size, and leave certain interval, and so that keep glue-line, in unit ceramic block patchhole successively, compacting; Working surface, leading edge at draught fan impeller 3 blades process dovetail groove or rectangle groove, at hub disk position processing easy to wear circular hole, the place coats inorganic glue at slotted eye, the unit ceramic block is mounted in the corresponding slotted eye one by one, compacting, heating cure can obtain a complete ceramic stiff dough, increases wear resistance.Should notice during installation and processing that adjacent two row unit ceramic block seams stagger mutually, edge's build-up wear-resistant alloy-layer of ceramic plane on impeller 3 hub disks is in case solid grain washes away steel plate below ceramic layer.The unit special ceramic block 6 that is bumped on the utility model casing 1 and glueds joint is convex, the leading edge of impeller 3 blades be bumped into and the unit special ceramic block that glueds joint 9 for streamlined, impeller 3 blade root places be bumped into and the unit special ceramic block that glueds joint 7 for L shaped, be bumped into and unit special ceramic block 8 tops of glueing joint are rectangle at the front side of vane of impeller 3, the bottom is bumped into part and is swallow-tail form, edge's build-up wear-resistant alloy-layer of ceramic layer on impeller 3 hub disks is bumped on impeller 3 hub disks and the unit special ceramic block that glueds joint 10 is convex.Unit special ceramic block 6 and hub disk place unit special ceramic block 10 column parts are for being bumped into the splicing part on the utility model casing 1, partly for being bumped into the splicing part, the streamlined unit of blade leading edge special ceramic block 9 projection sections are for being bumped into the splicing part for the dovetail of the L of blade root place type unit special ceramic block 7 and front side of vane unit special ceramic block.1 is casing among the utility model Fig. 1, Fig. 2, and 2 is intake grill, and 3 is impeller, and 4 is main shaft, and 5 is ceramic layer.
Characteristics of the present utility model: 1. pottery do not come off, long service life, wear-resistant, high temperature resistant; 2. energy-efficient, the economic benefit height.
