In this way, the actual positions of the simulation nozzle and the nucleon device during installation are detected, and the accuracy and the applicability of the detection result can be better ensured.
Further, the lower part of the nozzle module is also provided with a nozzle interface adjusting mechanism, the nozzle interface adjusting mechanism comprises a solid and integrally cylindrical mounting sleeve, an inner cavity of the mounting sleeve is provided with an inner thread matched with an outer thread of a nozzle mounting end and forms the nozzle interface, and the adjusting mechanism can adjust the inclination angle of the mounting sleeve.
Like this, rely on adjustment mechanism to adjust installation cover inclination, and then can realize the regulation to nozzle installation angle, and then can realize the detection to the cooperation atomization effect between nozzle and the nucleon ware of different angles. Therefore, when the test device is used for product design test, the inclined matching angle of the optimal atomization effect between the nozzle and the nucleon device can be detected. When the device is used for detecting the quality of products, the actual installation angle between the nozzle and the nucleon device can be better simulated for detection, and the quality of the products can be more accurately reflected.
Therefore, it can be seen that based on the above device, the invention actually discloses a design method of the atomizing component of the snowmaking machine, namely, after the respective model sizes of the nozzle and the nucleon are determined (the respective model sizes of the nozzle and the nucleon can be confirmed according to experience according to the product model sizes of the snowmaking machine), the nozzle and the nucleon are installed in parallel and connected into a water supply system and a gas supply system and simulate the working condition of the water supply system to carry out the test, the deviation angle between the nozzle and the nucleon is correspondingly adjusted (can be adjusted according to the size of 1-3 degrees each time) each time, the coupled atomizing flow field condition is detected and recorded, and when the coupled water mist flow field particle size distribution range is minimum, the installation angle between the nozzle and the nucleon is the optimal matched design angle between the nozzle and the nucleon of the model. Thus, the snowmaking machine obtained by the design method can produce snowflake effect with most uniform and stable particle size and highest efficiency, and obtain the best snowmaking effect.
Specifically, as an optimized structural form of the nozzle interface adjusting mechanism, the nozzle interface adjusting mechanism further comprises a pressing block, the edge of the pressing block is detachably fixed at the lower end of the nozzle module by means of a screw, an opening is formed in the middle position of the pressing block, which is opposite to the opening of the lower end of the inner cavity of the nozzle module, the opening of the pressing block and the opening of the lower end of the inner cavity of the nozzle module are integrally formed in a circular mounting cavity in a left-right direction (namely, the direction of a vertical plane where the nucleon and the nozzle are located after the nucleon are mounted), the outer surface of the mounting sleeve is in a matched circular shape in the left-right direction, the mounting sleeve is tightly pressed and fixed in the mounting cavity, and the lower end of the mounting sleeve is provided with a section exposed out of the pressing block.
Therefore, the installation cavity and the outer surface of the installation sleeve are in a matched round shape, and the lower end of the installation sleeve is provided with a section of part exposed out of the press-connection block, so that after the screw is loosened, the direction of the installation sleeve can be rotated, the inclination angle can be adjusted, and then the installation sleeve is pressed and fixed again by the screw. Therefore, the adjustment of the installation angle between the nozzle and the nucleon device can be conveniently and rapidly realized, and the device has the advantages of simple structure, rapid adjustment, convenience, reliability and the like.
Further, the outer surface of the mounting sleeve and/or the inner surface of the mounting cavity are/is provided with an elastic material layer.
In this way, sealing can be better achieved and the compacting and fixing effect on the mounting sleeve can be guaranteed.
As another structural form of the nozzle interface adjusting mechanism, the upper end and the lower end of the mounting sleeve are connected with the nozzle module by adopting flexible sealing materials, an adjusting area capable of flexibly deforming is formed around the mounting sleeve, magnetorheological fluid is filled in the adjusting area, and electromagnets are further mounted at the left end and the right end of the adjusting area (namely, in the direction of the vertical plane where the nucleon and the nozzle are located after the nucleon is mounted).
Thus, when installed, the magnetorheological fluid should be in the range of the magnetic field of the electromagnet. When the electromagnet is powered off, the magnetorheological fluid is in a fluid property, and the deflection angle of the mounting sleeve in the left-right direction can be freely adjusted; after the angle of the installation sleeve is adjusted in place, the electromagnet is connected, and the magnetorheological fluid is hardened under the action of the magnetic field to fix the angle of the installation sleeve. Therefore, the deviation angle between the installed nozzle and the nucleon device can be conveniently and rapidly adjusted by utilizing the characteristics of the magnetorheological fluid. Meanwhile, in the structure, a section of flexible sealing material is connected between the upper end of the mounting sleeve and the nozzle module; therefore, the structure can also realize the adjustment of the installation sleeve in the height direction and the angle difference in other directions according to the requirement. Therefore, the device is used for quality detection, and can better simulate the actual conditions of angle deviation (including horizontal direction angle deviation and vertical direction angle deviation) and height deviation between nozzles and nucleon devices of different product models; greatly improves the quality detection effect. When the device is used for designing an atomization component product, the nozzle and the nucleon can be adjusted to be in different angle deviations in the vertical direction and the horizontal direction in each test, and the atomization flow field data after coupling under various different conditions is detected and recorded under the condition that the height direction is in different distances, and when the particle size distribution range of the coupling water mist flow field is minimum, the size of the installation angle and the size of the height gap (namely the front-back direction gap) between the nozzle and the nucleon are the optimal matching positions of the nozzle and the nucleon of the model. Thus, the relative position (comprising the data of the horizontal deflection angle, the vertical deflection angle and the height direction distance) between the nozzle and the nucleon device, which can generate the maximum snow making effect, can be obtained. The designed snow making machine is guaranteed to have the best snow making effect.
When the device is used for detection, the performance parameters of the water mist flow field sprayed by the single nozzle and the single nucleon device in the respective working states can be detected respectively to judge whether the requirements are met; and detecting the performance parameters of the coupled water mist flow field sprayed in the working state after the single nozzle and the single nucleon device meeting the requirements are matched, and judging that the nozzle and the nucleon device meet the matching requirements if the particle size distribution range of the coupled water mist flow field is detected to be larger than the maximum value of the particle size distribution range of the single nucleon device and smaller than the maximum value of the particle size distribution range of the single nozzle.
Therefore, the performance detection of the nozzle and the nucleon can be finished independently, and the coupling detection of the nozzle and the nucleon meeting the performance can be performed. Because according to the snow forming principle of the snow making machine, the water mist flow field sprayed by the nozzle and the water mist flow field sprayed by the nucleon device can simultaneously generate the breaking action and the fusion action of water mist drops when in coupling collision. When coupling, if the sauter average diameter of the water mist flow field is reduced, the collision crushing effect between the liquid drops is considered to be stronger than the mutual fusion, otherwise, the mutual fusion effect is considered to be larger than the collision crushing effect. Therefore, if the nozzle water mist flow field and the nucleon water mist flow field are coupled, more water mist drops with small particle size sprayed by the nucleon can be fused and then increased, and if the water mist drops with relatively large particle size sprayed by the nozzle can be collided and crushed as much as possible, the snow making effect can be better improved. Therefore, by adopting the detection method, the advantages and disadvantages of the matched snow making effect between the nozzle and the nucleon device can be detected, and whether the detected nozzle and the detected nucleon device are suitable for matching can be judged. Therefore, a better judging method can be provided for the design and actual effect detection of the snow making machine.
More specifically, the device may specifically include the following steps when in use:
1) Finishing the atomization characteristic detection of the single nozzle; installing a nozzle to be detected on a test frame, connecting a water pipe of a water supply system with the nozzle and providing working water pressure to spray water mist, taking a video camera and inputting the video camera into a computer to calculate and obtain the atomizing cone angle of a nozzle water mist flow field, comparing the atomizing cone angle of the nozzle with a preset value, and judging that the quality of the nozzle is not in accordance if the requirement is not met; if the atomizing cone angle of the nozzle meets the requirement, detecting the particle size distribution range of the water mist flow field of the nozzle by means of a particle size analyzer, obtaining the sauter average particle size, comparing the sauter average particle size of the nozzle with a preset value, if the sauter average particle size of the nozzle does not meet the requirement, judging that the quality of the nozzle is not met, and if the sauter average particle size of the nozzle meets the requirement, executing the next step;
2) Finishing the detection of the atomization characteristics of the single nucleon device; the method comprises the steps of mounting a nucleon to be detected on a test frame, respectively connecting a water pipe of a water supply system and an air pipe of an air supply system to the nucleon, providing working water pressure and air pressure to spray water mist, taking a camera to obtain a video, inputting the video into a computer to calculate and obtain the atomized cone angle of a water mist flow field of the nucleon, comparing the atomized cone angle of the nucleon with a preset value, and judging that the quality of the nucleon is not consistent if the requirement is not met; if the atomization cone angle of the nucleon device meets the requirement, detecting the particle size distribution range of the water mist flow field of the nucleon device by means of a particle size analyzer, obtaining the sauter average particle size, comparing the sauter average particle size of the nucleon device with a preset value, if the sauter average particle size of the nucleon device does not meet the requirement, judging that the quality of the nucleon device is not met, and if the sauter average particle size of the nucleon device meets the requirement, executing the next step;
3) The method comprises the steps that a nozzle and a nucleon device meeting the requirements in the first step and the second step are installed on a test frame in parallel according to the interval requirement, a shared water supply system is connected to the nozzle and the nucleon device, and a gas supply system is connected to the nucleon device, so that the nozzle and the nucleon device spray water mist together under the working water pressure and the working air pressure conditions, and a coupling water mist flow field is formed; and detecting the particle size distribution condition of the coupled water mist flow field by adopting a particle size analyzer, and judging that the nozzle and the nucleon device meet the matching requirement if the particle size distribution range of the coupled water mist flow field is detected to be larger than the maximum value of the particle size distribution range of the single nucleon device and smaller than the maximum value of the particle size distribution range of the single nozzle.
In this way, it can be better judged whether the performance of the single nozzle and the nucleon device is qualified or not, and whether the coupling matching effect is qualified or not.
Further, in the third step, the number of the nozzles may be adjusted to one or two for detection.
Therefore, the two nozzles are matched with the nucleon device in the partial snowmaking machine, so that the matched snow making effect of two different conditions can be conveniently detected.
Further, in the third step, the size of the mutual inclination angle between the nozzle and the nucleon device can be sequentially adjusted, then the detection is performed, the condition that the coupling water mist flow field particle size distribution range is the smallest is selected as the optimal value in the inclination angle meeting the requirement, and the corresponding inclination angle is recorded.
Therefore, because the nozzles and the nucleon devices in the partial snowmaking machine are in inclined fit, when the particle size distribution range of the coupling water mist flow field is small, the manufactured snowflakes are more uniform, and the snowmaking quality is more stable and reliable. Therefore, the optimal inclination angle between the nozzle and the nucleon device can be tested by the method, and a basis is provided for product design.
Further, in the third step, the size of the front-back gap between the nozzle and the nucleon device can be sequentially adjusted, then the detection is performed, the condition that the coupling water mist flow field particle size distribution range is the smallest is selected as the optimal value in the front-back gap meeting the requirement, and the corresponding front-back gap size is recorded.
Therefore, because the front-back gap exists between the nozzle and the nucleon in the partial snowmaking machine, when the particle size distribution range of the coupling water mist flow field is small, the manufactured snowflake is more uniform, and the quality of the manufactured snowflake is more stable and reliable. Therefore, the optimal front-back dislocation distance between the nozzle and the nucleon device can be tested by the method, and a basis is provided for product design.
In summary, the invention has the advantages of more conveniently and rapidly testing the atomization effect and the matching effect of the atomizing component of the snowmaking machine, so as to be beneficial to realizing product research and development improvement and product quality inspection judgment.
