Background technology
At present, grow as equipment manufacture continues to develop, abrasive blast equipment purposes is more and more, on Chinese patent publication
A kind of split boron carbide blast nozzle is disclosed, is made up of nozzle aperture, mouth body, wherein mouth body is made up of split one and split two, split
One and split two be combined the boron carbide blast nozzle to form a whole, centre sets nozzle aperture；Although boron carbide is wear-resisting with its
Resistant to elevated temperatures characteristic is widely used in the manufacturing of blast nozzle, but this boron carbide blast nozzle is used in abrasive blast equipment still
The problem of anti-wear performance and inadequate resistance to elevated temperatures be present, easily reduce its service life because of high speed sandblasting, moreover, this
The toughness of kind blast nozzle is also inadequate, easily causes to damage in use.Now with the continuous hair of zirconia ceramics material application
Exhibition, has there is application of the ceramic sand jet in abrasive blast equipment, but existing ceramic sand jet although possess have it is enough strong
Degree, but toughness is the absence of, it therefore, can equally cause to use upper rapid wear, reduce service life, and existing ceramic sand jet
There is also unreasonable in structure, flow velocity is not high enough, thus the effect of derusting by sandblasting is not ideal enough.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of simple in construction, making side
Just, cost of manufacture can be reduced, flow velocity is high, supercharging is fast, wear-resistant, corrosion-resistant, resistance to erosion, resistant to elevated temperatures composite ceramics blast nozzle.
The purpose of this utility model is completed by following technical solution, a kind of composite ceramics blast nozzle, it be by
The ceramic material that 25-35% zirconium oxide and 65-75% alumina composite form is after injection or compression molding in hot environment
Nozzle body is made in lower sintering, and described nozzle body is made up of preceding first pressure inlet and the second pressure inlet to connect after, institute
The first pressure inlet stated is integrally formed by leading portion straight pipe and back segment conical horn shape collapsible tube, and the second described pressure inlet is one
The taper draw of long section small-angle is formed, and the second described pressure inlet front end small-caliber end portion is located at the first pressure inlet rearward end
At a distance of many 15mm distances in heavy caliber pore or with the heavy caliber pore of the first pressure inlet rearward end.
As preferred：The length of first pressure inlet is 90-110mm, and the pipe range of back segment conical horn shape collapsible tube is
35—45mm；The caliber of leading portion straight pipe is 9-10mm；The maximum caliber of back segment conical horn shape collapsible tube is 23-27mm；
The length of second pressure inlet is 55-65mm, and the second pressure inlet front end is connected on the pipe end bore of the first pressure inlet rearward end
For 11-13mm, the pipe end bore of rearward end is 14-16mm.
As preferred：First pressure inlet and the second pressure inlet are installed in the shell of derusting by sandblasting equipment and wrapped
Wrap up in, the heavy caliber pore of the second described small-bore end in pressure inlet front end and the first pressure inlet rearward end at a distance of 8-12mm away from
From.
The utility model have it is simple in construction, it is easy to make, can reduce cost of manufacture, flow velocity is high, supercharging is fast, it is wear-resistant,
The features such as corrosion-resistant, resistance to erosion, high temperature resistant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing：It is described in the utility model a kind of multiple shown in Fig. 1
Ceramic sand jet is closed, it is by injection or mould by the ceramic material that 25-35% zirconium oxide and 65-75% alumina composite form
Nozzle body is made in sintering in high temperature environments after molded, and described nozzle body connects by preceding first pressure inlet 1 and after
The second pressure inlet 2 form, the first described pressure inlet 1 is by 4 integral structure of leading portion straight pipe 3 and back segment conical horn shape collapsible tube
Into the second described pressure inlet 2 is that the taper draw for growing section small-angle is formed, and the described front end of the second pressure inlet 2 is small-bore
End is located in the heavy caliber pore 5 of the rearward end of the first pressure inlet 1 or the phase of heavy caliber pore 5 with the rearward end of the first pressure inlet 1
Away from many 15mm distances.
A kind of embodiment of the present utility model is：The length L1 of first pressure inlet 1 is 90-110mm, back segment taper
The pipe range L2 of horn-like collapsible tube 4 is 35-45mm；The caliber R1 of leading portion straight pipe 3 is 9-10mm；Back segment conical horn shape is received
The maximum caliber R2 of the draw 4 is 23-27mm；The length L3 of second pressure inlet 2 is 55-65mm, the front end of the second pressure inlet 2
The pipe end bore R3 for being connected on the rearward end of the first pressure inlet 1 is 11-13mm, and the pipe end bore R4 of rearward end is 14-16mm.
