Specific embodiment
Embodiment 1
A kind of high-pressure jet spray head, as shown in Figure 1, include Stainless Steel Shell 1, jet stream flow path features 2, stainless steel spring 3,
Sealing cover 4, sealing ring 5, cushion chamber 6, sealing cover 4 are equipped with the first inlet 7, and one end of shell 1 is equipped with the first liquid outlet 8, separately
One end and sealing cover 4 fasten, and sealing ring 5 is set between sealing cover 4 and shell 1；Jet stream flow path features 2 are set in shell 1,
One end is equipped with the second inlet 9, and the other end is equipped with the second liquid outlet 10；Elastomeric element 3 is set to jet stream flow path features 2 and sealing
Between lid 4, sealing cover 4 compresses elastomeric element 3 in fastening, and the compression of elastomeric element 3 generates elastic force for jet stream flow path features
2 are fixed with shell 1；Cushion chamber 6 is by the front end face of jet stream flow path features 2 and the inner wall of shell 1 and the inner wall of sealing cover 4
It surrounds and is formed.
After material slurry is pressurizeed by high-pressure plunger pump, high-pressure jet spray head is entered by the first inlet 7, by cushion chamber 6
Afterwards, material slurry is entered in jet stream flow path features 2 by the second inlet 9 carries out jet mill, and smashed screened stock liquid successively passes through
It crosses the second liquid outlet 10 and the first liquid outlet 8 discharges.
It is tight as suffered by jet stream flow path features when carrying out the assembling of high-pressure jet spray head using the structure in the present embodiment
Gu power be it is controllable, jet stream flow path features be able to maintain it is intact, high-pressure jet spray head assembling yield rate be greater than 99%.
For the high-pressure jet spray head of the present embodiment when carrying out the crushing of soybean milk material, soya-bean milk thick first is by high-pressure plunger
Pump is forced into 120MPa, and after cushion chamber buffers, the pressure oscillation of soya-bean milk passes through jet stream flow path features powder within ± 2MPa
Thin soya-bean milk partial size d90 after broken is 41.5 microns, production capacity 450L/h.Simultaneously as pressure oscillation is smaller, pressure is reduced
The impact for jet stream flow path features is fluctuated, so that serviceability rate of the jet stream flow path features in long-time use is greater than 99%.It is complete
The calculation method of availability ratio are as follows: during 120MPa, 2000 hours production and applications, Traffic Anomaly occurs, i.e. flow sports
± 10% or more of normal discharge is then determined as that the jet stream flow path features of the spray head are damaged, and serviceability rate=1- is damaged
Spray head number/total spray head number.
Comparative example
High-pressure jet spray head in the prior art, as shown in Fig. 2, being connect including shell 201, jet stream flow path features 202, sealing
First 203, fastening nut 204, sealing ring 205, inlet 206, liquid outlet 207.Jet stream flow path features are located in shell, both ends with
Seal nipple connects.Fastening nut pushes the seal nipple at both ends mobile to center and applies pressure, so that jet stream in fastening
Sealing is realized between the both ends and seal nipple of flow path features.
When being assembled using the structure in comparative example, due to jet stream flow path features applied by seal nipple it is tight
Solid pressure power is difficult to control, and fastening pressure is small, poorly sealed to leak, and fastening pressure crosses conference and makes jet stream flow path features
It is damaged, therefore the serviceability rate of work in-process jet stream flow path features is lower, the yield rate of high-pressure jet spray head assembling is only
80% or so.
For high-pressure jet spray head in the prior art when carrying out the crushing of soybean milk material, soya-bean milk thick first is by high-pressure column
Plug pump is forced into 120MPa, and the pressure oscillation of soya-bean milk passes through the smashed thin soya-bean milk partial size d90 of jet stream flow path features in ± 5MPa
It is 62.4 microns.When the high-pressure jet spray head of embodiment 1 and the high-pressure jet spray head of comparative example carry out soybean milk crushing,
The particle diameter distribution comparison diagram of thin soya-bean milk is as shown in Figure 6 after crushing.It can be seen that after the high-pressure jet spray head in embodiment 1 crushes
Soybean milk partial size d90 it is smaller, and the distribution of partial size is narrower.
Since pressure oscillation is larger, jet stream flow path features are by biggish impact, so that jet stream flow path features are in use
Also it is easy to be damaged, so that serviceability rate of the jet stream flow path features in long-time use is only 60% or so, so that this sets
It is standby to be difficult to be applied in the production of practical soya-bean milk.The calculation method of serviceability rate are as follows: in 120MPa, 2000 hours production and applications
In the process, Traffic Anomaly occurs, i.e. flow sports ± 10% or more of normal discharge, is then determined as the jet stream runner of the spray head
Component is damaged, the spray head number that serviceability rate=1- is damaged/total spray head number.
Therefore, embodiment 1 simplifies the assembly of high-pressure jet spray head first, prevents jet stream compared with comparative example
Damage of the road component in assembly；Secondly, can use the pressure of high-pressure pump generation, it is automatic to realize jet stream flow path features and shell
Between sealing；Third, design have cushion chamber, can reduce pressure oscillation, improve crushing effect, reduce the partial size point of material
Cloth, while impact of the pressure oscillation for jet stream flow path features is reduced, reduce the risk of its damage.
Embodiment 2
A kind of high-pressure jet Nozzle At The Ingot Mold group, as shown in figure 3, wherein sectional view is as shown in Figure 4.Including high-pressure jet spray head knot
Structure 301, integral housing 302, inlet 303, liquid outlet 304.The wherein high pressure in high-pressure jet nozzle structure and embodiment 1
Fluid jet nozzle is almost the same, and only the position of the first inlet is changed to be set to the side for buffering cavity shell by being arranged on sealing cover
On wall, and cushion chamber is interconnected, unified to be fed by inlet 303.First liquid outlet of each high-pressure jet nozzle structure also phase
It is intercommunicated.
As it can be seen that embodiment 2 compared with comparative example, can easily realize the expansion of production capacity in same overall structure
Greatly.
For the high-pressure jet Nozzle At The Ingot Mold group of the present embodiment when carrying out the crushing of soybean milk material, soya-bean milk thick first is by high pressure
Plunger pump is forced into 120MPa, and after cushion chamber buffers, the pressure oscillation of soya-bean milk passes through jet stream runner within ± 2MPa
The smashed thin soya-bean milk partial size d90 of component is 42.6 microns, production capacity 5400L/h.The high-pressure jet spray head and reality of embodiment 1
When applying the high-pressure jet Nozzle At The Ingot Mold group progress soybean milk crushing of example 2, particle diameter distribution comparison diagram such as Fig. 7 institute of thin soya-bean milk after crushing
Show.As it can be seen that embodiment 2 is compared with Example 1, production capacity imitates the crushing of soybean milk while increasing 12 times
Fruit and single high-pressure jet spray head are almost the same.
Embodiment 3
A kind of high-pressure jet spray head, as shown in Figure 5.It further include two groups of sealings compared with 1 mesohigh fluid jet nozzle of embodiment
Circle 11, wherein another group is set to jet stream flow path features 2 between one group of side wall for being set to jet stream flow path features 2 and shell 1
Between rear end face and shell 1.Sealing can be better achieved in the addition of two groups of sealing rings, while reducing for machining essence
The requirement of degree.
The embodiments of the present invention has been described in detail above, but also only to facilitate understand and explanation and illustrate,
