Abstract
The utility model discloses a granulation nozzle which comprises a nozzle body with a cavity and a rotary body (20) and a nozzle (30) arranged in the nozzle body. The space enclosed by the rotary body (20) and the nozzle (30) is a swirl chamber. The granulation nozzle further comprises a hole core (33) installed in the nozzle (30) to retain the distribution and fog distance of the particles sprayed from the granulation nozzle. The granulation nozzle is long in service lifetime, and easy for maintenance.
Description
Technical field
The utility model relates to prilling nozzle, particularly, relates to a kind of prilling nozzle for the production of catalyst granules.
Background technology
At present, along with the development of chemical industry, the use amount of catalyst is also increasing.And as the particle of catalyst carrier, its quality often can affect the service efficiency of catalyst etc.
In the spray step of one of important step of producing catalyst granules, conventionally use these three kinds of high speed centrifugal atomization device, air-current atomising device and pressure atomizer.
Wherein, utilize the press atomization system of pressure atomizer, in prior art, nozzle as shown in Figure 1, includes and has the nozzle body 1 of cavity and be arranged on rotary body 2 and the spout 3 in described nozzle body, and the quality of the particle that press atomization system is produced is decided by nozzle often.
But, due to the inner face of rotary body 2 and spout 3 be contact with raw material for the manufacture of catalyst granules and easily wearing and tearing under the washing away of raw material, thereby cannot make the size distribution that sprays from prilling nozzle and mist apart from maintaining all the time.Even if use the superhard material of tungsten carbide and carborundum class, its service life is also shorter.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of prilling nozzle, and this prilling nozzle can make the size distribution and the mist distance that from prilling nozzle, spray maintain all the time, long service life, and easily safeguard.
In order to solve the problems of the technologies described above, the utility model provides a kind of prilling nozzle, this prilling nozzle comprises having the nozzle body of cavity and be arranged on rotary body and the spout in described nozzle body, the space that described rotary body and described spout surround is spin chamber, and this prilling nozzle also comprises the Kong Xin being arranged on described spout.
Preferably, described Kong Xin is diamond hole core.
Preferably, described Kong Xin is arranged on described spout by welding, press-fiting or bond.
Preferably, described spout is formed with the step surface that is positioned at this spout bottom, and described Kong Xin is arranged on described step surface.
Preferably, on the inner surface of described spout and/or the inner surface of described rotary body, be provided with wearing layer.
Preferably, described wearing layer is diamond coatings.
Preferably, described wearing layer applies by depositing operation or spraying coating process.
Pass through technique scheme, the utility model improves the wear-resistant degree of above-mentioned prilling nozzle by being arranged on independently hole core on spout, and the size distribution and the mist distance that from prilling nozzle, spray are maintained all the time, thereby can extend the service life of prilling nozzle.
Other feature and advantage of the present utility model partly in detail are described the specific embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, but does not form restriction of the present utility model with the specific embodiment one below.In the accompanying drawings:
Fig. 1 is the structure of the prilling nozzle of prior art.
Fig. 2 is the structure (utilizing heavy black line to represent described wearing layer) of prilling nozzle described in the utility model

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
As shown in Figure 2, the utility model provides a kind of prilling nozzle, this prilling nozzle comprises having the nozzle body of cavity and be arranged on rotary body 20 and the spout 30 in described nozzle body, the space that described rotary body 20 and described spout 30 surround is spin chamber, and this prilling nozzle also comprises the hole core 33 being arranged on described spout 30.Because described hole core 33 is relatively independently to arrange with described spout, thereby can reduce the holistic cost of described spout.That is to say, in order to extend the service life of described prilling nozzle, and need to use, price is higher, hardness is higher, more wear-resisting material.And the utility model only forms the bottom spray orifice of stressed higher spout independently Kong Xin, thereby reduce the use amount of the material that price is higher.This material can be than tungsten carbide and the high of the prior art any material of carborundum hardness.As a kind of specific embodiment of the present utility model, described hole core 33 is diamond hole core.
Described diamond hole core can also be arranged in described nozzle body by dismountable mode, thereby changes easily described diamond hole core, extends further the service life of described prilling nozzle.
Particularly, described hole core 33 can be by welding, press-fit or the prior art such as bonding is arranged on described spout 30.
As a kind of specific embodiment of the present utility model, described spout 30 is formed with the step surface 34 that is positioned at this spout bottom, and described hole core 33 is arranged on described step surface 34.
As a kind of specific embodiment of the present utility model, on the inner surface of the inner surface of described spout 30 and/or described rotary body 20, be provided with wearing layer.
As a kind of specific embodiment of the present utility model, described wearing layer is diamond coatings.
Particularly, described wearing layer applies by depositing operation, spraying coating process.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
