Description

Technical Field

[0001] This utility model relates to the field of fluid jetting and precision component cleaning technology, and in particular to a two-fluid jetting nozzle and a two-fluid washing device for cleaning bearings. Background Technology

[0002] In modern industrial production, bearings, as indispensable core components of mechanical equipment, play a crucial role in the operational stability, service life, and efficiency of the equipment due to their cleanliness. Currently, common bearing cleaning methods include pure liquid cleaning, ultrasonic cleaning, chemical solvent cleaning, and high-pressure gas purging. While pure liquid cleaning is relatively simple to operate, the scouring force of the liquid is limited, making it difficult to effectively remove stubborn oil and impurities, and easily leaving cleaning residue. Ultrasonic cleaning removes dirt through the cavitation effect generated by high-frequency vibration; however, this method may damage some bearings with delicate structures and special materials. Chemical solvent cleaning, while having strong cleaning power, suffers from solvent residue, environmental pollution, and corrosion of bearing materials. High-pressure gas purging is insufficient to completely remove grease and microparticles adhering to the bearing surface. With the increasing demands for bearing cleanliness in industrial production, developing a bearing cleaning technology and equipment that overcomes these shortcomings and achieves efficient, non-destructive, and environmentally friendly cleaning has become an urgent problem to solve. Summary of the Invention

[0003] According to an embodiment of the present invention, a two-fluid jet nozzle is provided, comprising:

[0004] The main body has a cavity inside;

[0005] The main body has a first inlet at the top, a spray nozzle at the bottom, and a second inlet on one side;

[0006] The first inlet, the jet inlet, and the second inlet are connected by a cavity.

[0007] Furthermore, the first inlet is a gas inlet, and the second inlet is a liquid inlet.

[0008] Furthermore, the inlet pressure of the first inlet is not less than 4 kg.

[0009] Furthermore, the nozzle is conical.

[0010] Furthermore, the entire spray nozzle is made of stainless steel.

[0011] According to another embodiment of the present invention, a two-fluid washing device for cleaning bearings is also provided, comprising a plurality of two-fluid jet nozzles of the previous embodiment.

[0012] The beneficial effects of this utility model are:

[0013] 1. High-efficiency cleaning: The two-fluid jet nozzle utilizes the mixed atomization of gas and liquid, combined with a gas inlet pressure of no less than 4 kg and the acceleration effect of the conical jet nozzle, to generate a jet stream with a powerful impact, which can quickly and effectively remove various dirt from the bearing surface. Compared with traditional cleaning methods, the cleaning efficiency is significantly improved.

[0014] 2. Non-destructive cleaning: This cleaning method avoids the mechanical damage that may be caused by ultrasonic cleaning and the material corrosion that may be caused by chemical solvent cleaning. While ensuring the cleaning effect, it can effectively protect the structure and performance of the bearing and is suitable for cleaning bearings of various materials and structures.

[0015] 3. High durability: The nozzle is made of stainless steel, which has excellent corrosion resistance and wear resistance. It can adapt to different cleaning liquids and working environments, reduce the damage and replacement frequency of the nozzle, and reduce the overall operating cost of the equipment.

[0016] 4. All-round cleaning: The two-fluid washing equipment achieves all-round spray cleaning of the bearing through the coordinated work of multiple two-fluid spray nozzles, ensuring that all parts of the bearing are thoroughly cleaned, effectively improving the cleaning quality of the bearing and providing a guarantee for the stable operation of the mechanical equipment.

[0017] The two-fluid jet nozzle and the two-fluid washing equipment for cleaning bearings according to the embodiments of this utility model effectively improve the cleanliness of bearings and reduce the risk of damage to precision parts during the cleaning process.

[0023] Figure 5 for Figure 4 Enlarged view of point A. Detailed Implementation

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0025] First, combine Figures 1-5 The description of the two-fluid jet nozzle according to an embodiment of the present invention is for bearing cleaning and has a wide range of applications.

[0026] like Figures 1-3 As shown, the two-fluid jet nozzle of this utility model embodiment includes:

[0027] Body 1, with a cavity 11 inside body 1;

[0028] The main body 1 has a first inlet 12 at the top, a spray nozzle 13 at the bottom, and a second inlet 14 on one side;

[0029] The first inlet 12, the jet outlet 13, and the second inlet 14 are connected through the cavity 11.

[0030] Furthermore, such as Figure 1 , 3 As shown, in this embodiment, the first inlet 12 is a gas inlet and the second inlet 14 is a liquid inlet.

[0031] Furthermore, such as Figure 1 , 3 As shown, in this embodiment, the inlet pressure of the first inlet 12 is not less than 4 kg. The higher gas inlet pressure can provide strong power for the injection of the mixed fluid, driving the liquid to be ejected at a higher speed and with higher energy, thereby enhancing the cleaning ability of the nozzle.

[0032] Furthermore, such as Figure 1 , 3 As shown, in this embodiment, the nozzle 13 is conical, which can effectively guide and accelerate the mixed fluid. When the mixed fluid flows through the conical nozzle 13, the fluid velocity increases continuously as the flow cross-section gradually decreases, thereby forming a jet stream with strong impact force and concentration, which helps to remove dirt from the surface of the bearing 2 more efficiently.

[0033] Furthermore, in this embodiment, the entire spray nozzle is made of stainless steel. Stainless steel has excellent corrosion resistance, wear resistance, and high strength, enabling it to operate stably in various complex working environments. It can not only resist the erosion of cleaning liquids and gases, but also withstand the mechanical stress brought about by long-term high-frequency spraying operations, effectively extending the service life of the nozzle and reducing equipment maintenance costs.

[0034] Working Principle: When installing the two-fluid jet nozzle, first seal the gas pipeline to the first inlet 12 (gas inlet) to ensure a tight connection and prevent gas leakage; then securely connect the liquid pipeline to the second inlet 14 (liquid inlet). After installation, adjust the nozzle by regulating the gas pressure source to ensure the gas inlet pressure at the first inlet 12 reaches a set value of not less than 4 kg, and adjust the liquid flow rate according to actual cleaning needs. Turn on the nozzle and observe the spraying effect, checking whether the spraying of the mixed fluid is uniform and stable. If any abnormalities are found, adjust the gas pressure, liquid flow rate, or nozzle installation until the ideal spraying state is achieved.

[0035] Secondly, such as Figures 4-5 As shown, according to another embodiment of the present invention, a two-fluid cleaning device for cleaning bearings is also provided, comprising a plurality of two-fluid jet nozzles from the previous embodiment. By reasonably arranging the positions and angles of the multiple two-fluid jet nozzles, the device can spray and clean the bearing 2 from different directions. During cleaning, the inner ring of the bearing 2 can be rotated, achieving all-round, no-dead-angle cleaning of the bearing 2, greatly improving the efficiency and quality of bearing 2 cleaning.

[0036] Working principle: Place the bearing 2 to be cleaned on the cleaning station of the two-fluid washing equipment. Adjust the spray angle and position of the nozzle according to the specifications and shape of the bearing 2. Start the equipment, and multiple two-fluid spray nozzles inside the equipment work simultaneously. According to the preset program and parameters, the mixed gas and liquid are atomized in the cavity 11 and sprayed onto the bearing 2 for cleaning.

[0037] Above, refer to Figures 1-5 This invention describes a two-fluid jet nozzle and a two-fluid washing device for cleaning bearings according to embodiments of the present invention. The device effectively improves the cleanliness of bearings while reducing the risk of damage to precision parts during the cleaning process. It is suitable for bearing maintenance and cleaning of various high-precision mechanical equipment.
