Abstract
The utility model relates to a wear-resistant nozzle. The nozzle comprises a nozzle body and a liner, wherein the nozzle body is made of common metal materials; three stages of axial stepped holes are arranged in the nozzle body, namely a threaded hole, a liner installation hole and an orifice from back to front in sequence; the liner is made of wear-resistant materials and is installed in the liner installation hole through clearance fit; and a liner axle hole corresponding to the orifice is arranged in the liner. The nozzle has the following technical effects that: the integral nozzle is changed into a composite member formed by the nozzle body and the liner; and after the nozzle is worn, the liner only needs to be replaced, without replacing the nozzle body, thus saving the materials and lowering the cost.
Description
Technical field
The utility model relates to surface processing equipment, specifically a kind of wear-resisting nozzle that is used for sandblast or shot blasting equipment.
Background technology
Extensively adopt sandblast or shot blasting equipment to carry out surface treatment in the industrial processes.For example, when casting industry was leveled foundry goods, adopting sandblast or shot blasting equipment was power with quartz sand or shot through compressed air, to the cast(ing) surface cleaning of polishing; And for example, blasting treatment is carried out on the deduster surface, painted after rust cleaning, the polishing in environmental protection equipment factory.
Sandblast or shot blasting equipment all use nozzle.Existing nozzle is monolithic construction.Because in the production engineering, the effluxvelocity of sand grains or shot is up to 25 ~ 30m/s, nozzle abrasion is very big.In order to improve the life-span of nozzle, adopt wear resistant cast iron or abrasion-resistant stee foundry goods (employing crow steel that has or sign indicating number steel) in the prior art usually, but be 8 hour to calculate can only use about a week will change nozzle with per tour service life; The nozzle that the factory that has uses the rare alloy material of import to do, can reach three months service life, but because of the composition of containing metal iridium is high, cost an arm and a leg, and use cost is too high, neither long-term plan.
Summary of the invention
The utility model provides a kind of use cost low wear-resisting nozzle to the problems referred to above.
Technical scheme according to the utility model: a kind of wear-resisting nozzle comprises nozzle body and liner; Said nozzle body is processed by ordinary metallic material, is provided with three grades of axial shoulder holes in the said nozzle body, from after be followed successively by screwed hole, liner installing hole and spray orifice forward; Said liner is processed by high-abrasive material, and its gap is installed in the said liner installing hole ordinatedly, has in the said liner and the corresponding liner axis hole of said spray orifice.
The material of said nozzle body is cast iron or cast steel.
The front end of said nozzle body is pre-small post-large cone, and the rear end of said nozzle body is a cylinder.
Said liner is processed by ceramic material.
Said ceramic material is the white jade steel.
The tail end of said liner has taper hole.
Said screwed hole is a gas thread.
The technique effect of the utility model is: the utility model makes the nozzle of integral body into be made up of nozzle body and liner sub-assembly, behind the nozzle wear, only needs more changeable liner, need not change nozzle body, but economical with materials, reduces cost; Liner adopts ceramic material, and anti-wear performance is strong, cost is low, and the life-span is long, and production technology is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, comprise nozzle body 1, liner 2, spray orifice 3, step surface 4, liner axis hole 5, liner installing hole 6, taper hole 7, screwed hole 8 etc.
As shown in Figure 1, the utility model is a kind of wear-resisting nozzle, comprises nozzle body 1 and liner 2.
The utility model makes the nozzle of integral body into be made up of nozzle body 1 and liner 2 sub-assembly, and two parts are processed by different materials, and liner 2 is processed by high-abrasive material; Behind the nozzle wear; Only need more changeable liner 2, need not change nozzle body 1, but economical with materials, reduce cost; Liner 2 adopts ceramic material, and anti-wear performance is strong, cost is low, can be by the mould press forming, and production technology is simple; Adopt the nozzle of ceramic material liner 2, its life-span can reach three months, is more than 10 times of integrated nozzle that common wear resistant cast iron or abrasion-resistant stee foundry goods are processed, and the nozzle of processing with iridium alloy is suitable, but the nozzle that price is processed than iridium alloy is low more than 10 times.
