Abstract
The utility model discloses a ceramic nozzle. The ceramic nozzle comprises a nozzle head, a feeding pipe and a sleeving head, wherein the top end of the nozzle head is provided with a cylindrical nozzle, an inner cavity of the nozzle head is of a hollow cone-shaped structure, and the top end of the inner cavity of the cone-shaped inner cavity is communicated with the cylindrical nozzle; a connecting member is arranged at the bottom end of the nozzle head, is internally provided with internal threads, and is fixedly connected with the nozzle head; one end of the feeding pipe is provided with external threads, and the feeding pipe is in threaded connection with the nozzle head; a thread ring is arranged on the outer side of one end, close to the external threads, on the feeding pipe and is fixedly connected with the feeding pipe, and the external threads are arranged on the outer surface of the thread ring; one end of the sleeving head is clamped to the connecting member of the nozzle head, and the internal threads are arranged at the other end of the sleeving head and are in threaded connection with the thread ring on the feeding pipe. The ceramic nozzle has the beneficial effects that the abrasion resistance of the nozzle head is increased, the vibration in a sand blasting process is reduced, the nozzle head is effectively protected by virtue of a protecting ring on the sleeving head, and the defect of poor toughness of the ceramic nozzle is made up.
Description
Technical field
The utility model belongs to the technical field of abrasive blast equipment parts, is specifically related to a kind of ceramic nozzle.
Background technology
Ceramic material is that the mankind should have one of material early, and it is hard, stable, can fabrication tool, apparatus; In the situation that some are special, also can be used as structural material, ceramic material belongs to Inorganic Non-metallic Materials, is the compound of carbon containing hydrogen-oxygen combination not, is mainly metal oxide and metal non-oxidized substance.Because most of Inorganic Non-metallic Materials contains silicon and other element compound, so be called again silicate material.It generally comprises unorganic glass, glass ceramics and ceramic three classes.As structure and tool materials, industrial ceramics is in engineering, to apply one of pottery more widely, development along with abrasive jet machining technology and material science, also there are great changes in the material of manufacturing nozzle, because ceramic material aboundresources, hardness are high, wearability and Good Heat-resistance, in engineering, obtain a wide range of applications, as being used for, make the wear-resisting and corrosion-resistant part of the industries such as cutting tool, engine part, bearing parts and metallurgy, mine, coal, chemical industry.Just because of ceramic material possesses these advantages, so it has become to prepare the ideal material of nozzle, ceramic nozzle is compared with metal, the life-span of carboloy nozzle, working (machining) efficiency all has a more substantial increase, the main failure forms of blast nozzle is erosive wear, in abrasive jet machining, abrasive grain is more serious to the erosion of nozzle, the wear rate of nozzle is conventionally higher, cause nozzle diameter to increase rapidly, abrasive grain speed declines, thereby cause nozzle life to shorten, make abrasive jet machining Efficiency Decreasing, and abrasive jet amount is increased, increased abrasive jet machining cost, for guaranteeing abrasive jet machining efficiency, need the frequent nozzle of changing, operator's labour intensity is increased greatly.During due to abrasive blasting, impulsive force is larger, often can cause nozzle vibrations, and because vibration frequency is excessive, ceramic material toughness is lower, often can make shower nozzle shatter, and affects operating efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of ceramic nozzle for the defect of above-mentioned existence.
The technical solution of the utility model is: a kind of ceramic nozzle, comprise nozzle head, feed pipe, bell and spigot joint, described nozzle head top is cylindrical spout, the inner chamber of nozzle head is hollow conic structure, conical cavity top is communicated with cylindrical spout, nozzle head bottom is provided with connector, in connector, be provided with internal thread, connector is fixedly connected with nozzle head, one end of described feed pipe is provided with external screw thread, feed pipe is threaded with nozzle head, on feed pipe, near external screw thread one end arranged outside, there is threaded collar, threaded collar is fixedly connected with feed pipe, threaded collar outer surface is provided with external screw thread, described bell and spigot joint one end is connected on nozzle head connector, the other end is provided with internal thread, internal thread on bell and spigot joint is threaded with the threaded collar on feed pipe.
The further improvement of this programme also has, and is fixedly installed bell and spigot joint mat on above-mentioned connector.
The further improvement of this programme also has, and above-mentioned bell and spigot joint one end is provided with nozzle head protection ring, and protection ring is divided into inside and outside two-layer, and skin is made for metal material, and internal layer is tapetum.
The further improvement of this programme also has, and the outer field metal material of above-mentioned protection ring is carbide alloy, and underwool layer is bonded on outer layer metal layer.
The further improvement of this programme also has, and said nozzle head cross section is circular.
The further improvement of this programme also has, and above-mentioned bell and spigot joint mat is rubber cushion.
The beneficial effects of the utility model are: the structure of nozzle head, increased the wearability of nozzle head, and reduced the vibrations in sandblast process; protection ring on bell and spigot joint; effectively protected nozzle head, made up the shortcoming of ceramic nozzle toughness deficiency, nozzle head and feed pipe docking are convenient.
