Description

Technical Field

[0001] The present invention relates to the technical field of nozzle testing, and particularly relates to a nozzle atomization effect testing device and a testing method. Background Art

[0002] As is well known, with the continuous progress of technology, atomizing nozzles are increasingly widely used in many fields such as agriculture, industry, and medicine. In order to ensure the performance and quality of atomizing nozzle products, it is inevitable to test them. To facilitate the testing of the atomization effect of nozzles, we propose a nozzle atomization effect testing device and a testing method.

[0003] After retrieval, a patent with the Chinese patent application number CN201721205306.6 discloses a testing device for the atomization effect of a rotating cage nozzle. It is generally described as including a liquid supply system, an atomization system, and a testing system. The water pump of the liquid supply system extracts a solution from a water tank and enters a metering valve. The solution with adjusted pressure and flow rate is sent to the atomization system. The atomization system includes a rotating cage nozzle and a motor. The testing system includes a laser particle size analyzer, a pressure gauge, and a flow meter. When the support platform of the atomization system moves relative to the laser particle size analyzer, it simultaneously moves the motor and the rotating cage nozzle to a position opposite to the laser particle size analyzer, so that the laser emitted by the laser particle size analyzer can capture the circular spray surface ejected by the rotating cage nozzle. When in use, it can test the influence of factors such as pressure, flow rate, and motor speed on the atomization effect of the rotating cage nozzle.

[0004] Although the above-mentioned prior art solution can test the atomization effect of the rotating cage nozzle, during the testing process of the rotating cage nozzle, it is necessary to form detections under different pressures, different flow rates, and different motor speeds. And during the spraying process of the rotating cage nozzle, water mist particles will be distributed in the surrounding environment. Therefore, during the process of changing factors such as pressure, flow rate, and motor speed, the water mist ejected before the change of factors will inevitably affect the testing after the change of factors. Therefore, the reliability of the test data is poor. Summary of the Invention

[0016] S1. During use, first, through the clamping system, the corresponding sequential installation and clamping of multiple nozzles are formed. Then, the clamping system operates to achieve the synchronous rotation adjustment of the multiple nozzles, so that the multiple nozzles sequentially pass through the multiple insertion tubes respectively. When the multiple nozzles move to directly above the insertion tubes, the nozzles will fall through the insertion tubes and enter the space construction cylinders. Then, liquid is supplied to the nozzles, and then the nozzles will spray the liquid into the space construction cylinders and atomize the liquid.

[0017] S2. The atomized particles entering the space construction cylinder will be correspondingly detected by a laser particle size analyzer to achieve the quantification of the data on the atomization effect of the nozzle. After a single nozzle has completed spraying relative to the space construction cylinder, the clamping system operates to control the nozzle to be withdrawn from and inserted into the cylinder.

[0020] (1) In the present invention, through the provision of a laser particle size analyzer, a corresponding detection functional unit for the atomization particle size of the liquid sprayed by the nozzle is formed, and the quantification of the detection data is achieved.

[0021] (2) In the present invention, through the design of the clamping system, the nozzle capable of corresponding detection can be fixedly clamped and the liquid can be supplied, providing basic conditions for the detection of the nozzle, and it can also achieve the switching of the nozzle relative to the spraying position, realizing the automatic switching between multiple environments, with a relatively high degree of automation and detection efficiency.

[0022] (3) In the present invention, through the design of the atomization test structure, multiple independent spraying test spaces are formed to ensure the testing of the nozzle in multiple environments, and the test space has an independent cleaning function, with less mutual influence between the successive tests of multiple nozzles, and better practicability.

[0043] The laser particle size analyzer 2, the first servo motor 18, the electromagnet 31, and the second servo motor 38 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them and do not improve their structures and functions. For those skilled in the art, their setting methods, installation methods, and electrical connection methods can be debugged and operated as long as they comply with the requirements of their user manuals, and will not be elaborated here.

[0044] In summary, the working principle of the nozzle atomization effect testing device and the testing method is as follows. Before use, a controller is first installed for the laser particle size analyzer 2, the first servo motor 18, and the second servo motor 38. Through the controller, the operation control of the first servo motor 18 and the second servo motor 38 and the data reading of the laser particle size analyzer 2 can be achieved. And the controller has a data processing function supporting the laser particle size analyzer 2 to facilitate the processing and analysis of the data measured by the laser particle size analyzer 2. The power supply circuit is connected to the first access electrode 45 and the second access electrode 46. Multiple liquid supply holes are provided in the central column 5, and liquids with different pressures are supplied through the bottom ends of the liquid supply holes. Multiple guiding holes matching the liquid supply holes are also provided in the rotating connection cylinder 19, and the multiple guiding holes are respectively communicated with the multiple liquid supply holes 28. When a relative rotational adjustment is formed between the rotating connection cylinder 19 and the central column 5, the multiple liquid supply holes are respectively rotationally communicated with the multiple guiding holes in sequence to facilitate the formation of different hydraulic supplies in the multiple guiding holes. During use, first, the nozzles 1 are installed and clamped in corresponding sequence through the clamping system. Taking the front end where the outstretched fixing frame 51 is located as the installation station, the operator threads the nozzle 1 onto the threaded interface 27 at the bottom end of the lifting frame 26 that rotates into the installation station at the installation station, and then the corresponding installation of the nozzle 1 can be completed. After the installation is completed, the first servo motor 18 is powered on and runs. Under the meshing drive of the driving gear 22 and the driven gear ring 23, the rotation of the rotating connection cylinder 19 is driven. The rotation of the rotating connection cylinder 19 can drive the rotation of the multiple suspension brackets 24. The synchronous rotation of the multiple suspension brackets 24 realizes the rotation of the multiple outer rings 25. The rotation of the multiple outer rings 25 realizes the rotation of the multiple lifting frames 26. The rotation of the multiple lifting frames 26 makes the installed nozzles 1 rotate away from the installation station, and other lifting frames 26 are controlled to enter the installation station in sequence. When the nozzle 1 enters above the corresponding insertion cylinder 9, since the corresponding first contact electrode 41 and the second contact electrode 42 are respectively in contact with the first access electrode 45 and the second access electrode 46, in this state, the corresponding electromagnet 31 can be energized. The energized corresponding electromagnet 31 generates an electromagnetic field acting on the iron block 32 directly above the electromagnet 31, causing the iron block 32 to be attracted by the magnetic field and overcome the elastic spring 30 to drive the lowering of the lifting frame 26, controlling the nozzle 1 to fall through the top through hole 48 and the insertion cylinder 9. Finally, the nozzle 1 will enter the space construction cylinder 8. Since the side access port 29 will drop during the lowering process of the lifting frame 26, and when the side access port 29 drops and is communicated with the liquid supply hole 28, it happens that the nozzle 1 enters the corresponding position in the space construction cylinder 8. After that, the nozzle 1 will be communicated with the liquid supply hole, enabling the nozzle 1 to perform a spraying operation into the inserted space construction cylinder 8.

[0045] Further, the atomized particles entering the space construction cylinder 8 will be correspondingly detected by the laser particle size analyzer 2 to achieve the quantification of the atomization effect of the nozzle 1. During the spraying process of the nozzle 1 relative to the space construction cylinder 8, along with the slow rotation drive of the rotating frame 17 by the first servo motor 18, when the first contact electrode 41 rotates away from the first access electrode 45 and the second contact electrode 42 rotates away from the second access electrode 46, the electromagnetic field corresponding to the power-off of the electromagnet 31 disappears. Under the elastic action of the elastic spring 30, the lifting frame 26 rises and resets, and the corresponding nozzle 1 also rises and exits the space construction cylinder 8. At the same time, the communication between the side access port 29 and the liquid supply hole 28 that are interconnected also fails, cutting off the supply of the liquid in the nozzle 1. After that, when the nozzle 1 moves into the space construction cylinder 8 of the next working station, the operations of insertion and atomization of the nozzle 1 relative to the insertion cylinder 9 are repeated in the foregoing process to achieve the corresponding detection of the next pressure environment of the nozzle 1. The inner diameter of the insertion cylinder 9 is larger than the outer dimension of the nozzle 1, so that enough rotation space can be provided for the nozzle 1 in the insertion cylinder 9 to ensure that the first contact electrode 41 has enough rotation distance away from the first access electrode 45, and the second contact electrode 42 also has enough rotation distance away from the second access electrode 46. After the nozzle 1 forms an atomized spray relative to the space construction cylinder 8 and the laser particle size analyzer 2 completes the corresponding detection, the second servo motor 38 in the synchronous drive system is powered on and runs to drive the rotation of the combined gear ring 37. The rotation of the combined gear ring 37 drives the rotation of multiple transmission shafts 39 through multiple spur gears 40. The rotation of the transmission shafts 39 drives the movement of multiple transmission belts 12. The movement of the transmission belts 12 drives the movement of multiple sealing discs 13 connected thereto. During the movement of the multiple sealing discs 13 in the space construction cylinder 8, they can assist in guiding and cleaning the water mist in the space construction cylinder 8, so that the water mist in the space construction cylinder 8 is finally discharged through the liquid discharge cut-off pipe 10, cleaning the atomized particles in the space construction cylinder 8, and providing a good detection environment for the next spraying of the nozzle 1. When the first servo motor 18 is running, multiple outer rings 25 will drive the transmission ring 33 to rotate. The rotation of the transmission ring 33 drives the rotation of the internal gear ring 34. The rotation of the internal gear ring 34 drives the rotation of multiple transmission gear rings 36. The rotation of multiple transmission gear rings 36 respectively drives the rotation of multiple laser particle size analyzers 2 to adjust the target detection areas of multiple laser particle size analyzers 2, enabling the laser particle size analyzer 2 to perform circumferential multi-directional detection in cooperation with the atomized particles in the transparent section 14, making the detection data more abundant. After the detection is completed, by analyzing the collected data of the laser particle size analyzer 2, the evaluation of the atomization effect of the nozzle 1 can be achieved.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
