High-speed wind-driven atomizer

Abstract

This utility model belongs to the field of high-speed centrifugal rotary atomizers, especially wind-driven high-speed atomizers. Addressing the problem of low utilization rate of existing compressed air, which cannot effectively drive the atomizing components to rotate at high speed and thus affects the atomization effect, the following solution is proposed: An air cap is included, with a protective cover fixed to its bottom. A cavity is formed between the air cap and the protective cover. An upper bearing seat is fixed inside the air cap by bolts, and a lower bearing seat is fixed to its bottom. Both the upper and lower bearing seats contain ceramic bearings, and the same main shaft is fixed within the two ceramic bearings. An air chamber is formed between the lower and upper bearing seats. A wind turbine assembly for driving the main shaft rotation is fixed to the surface of the main shaft and is located within the air chamber. The design of the pressurization component ensures that the compressed air outlet diameter is smaller than the compressed air inlet diameter, effectively increasing the compressed air pressure by utilizing the difference in diameter.

Description

Technical Field

[0001] This utility model relates to the field of high-speed centrifugal rotary atomizers, and more particularly to wind-driven high-speed atomizers. Background Technology

[0002] In the field of liquid atomization, existing atomization equipment has many problems. Some atomizers are electrically driven, requiring complex circuit systems, which not only increases the cost of the equipment, but also poses safety hazards in environments with high explosion-proof requirements.

[0003] Other atomizers that use a pneumatic principle have an unreasonable structure, resulting in low utilization of compressed air and an inability to effectively drive the atomizing components to rotate at high speed, thus affecting the atomization effect. Furthermore, during operation, components such as bearings are prone to damage due to high temperatures, and dust easily accumulates on the surface of the atomizing wheel, affecting the uniformity of atomization and the normal operation of the equipment. Therefore, a new type of pneumatic high-speed atomizer is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low utilization of compressed air, inability to effectively drive the atomizing components to rotate at high speed, and thus affecting the atomization effect, by proposing a wind-driven high-speed atomizer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-speed wind-driven atomizer includes an air cap, a protective cover fixed to the bottom of the air cap, a cavity formed between the air cap and the protective cover, an upper bearing seat fixed inside the air cap by bolts, a lower bearing seat fixed to the bottom of the upper bearing seat, ceramic bearings provided in both the upper and lower bearing seats, a common main shaft fixed in the two ceramic bearings, a wind chamber formed between the lower and upper bearing seats, and a wind turbine assembly for driving the main shaft to rotate fixed on the surface of the main shaft, the wind turbine assembly being disposed within the wind chamber; A support is fixed to the surface of the lower bearing housing. A compressed air inlet is provided in the support for compressed air to enter. A pressurization assembly is provided in the lower bearing housing to increase the pressure of the compressed air. The cavity is equipped with an atomizing wheel, which is fixed to the surface of the main shaft.

[0006] In one possible design, the pressurization assembly includes an air duct for air supply formed between the lower bearing housing and the support, the air duct being connected to a compressed air inlet, and a compressed air outlet connected to the air duct being provided in the lower bearing housing, the radius of the compressed air outlet being smaller than the radius of the compressed air inlet. The compressed air outlet diameter is smaller than the compressed air inlet diameter, resulting in a height difference at the compressed air outlet, which drives the wind turbine assembly to rotate at high speed. In one possible design, in order to ensure the air pressure balance in the cavity, a lower air pressure relief outlet and an upper air pressure relief outlet are provided in the lower bearing housing. Pressure balancing can be achieved through the lower and upper air pressure relief outlets.

[0007] In one possible design, the upper air pressure relief outlet is provided in multiple locations, and the multiple upper air pressure relief outlets are evenly distributed at the top of the lower bearing seat. After the pressurized air drives the wind turbine assembly, it is divided into two parts. One part goes up to cool the ceramic bearing on the upper side and then is discharged through multiple upper air depressurization outlets.

[0008] In one possible design, there are four lower air pressure relief outlets, which are evenly distributed at the bottom of the lower bearing seat and are respectively connected to the air cavity and the air cavity. One portion of the material flows down through four lower air depressurization outlets into the cavity to cool the ceramic bearing on the lower side, while simultaneously blowing away dust from the atomizing wheel.

[0009] In one possible design, the four lower air depressurization outlets and the lower ceramic bearings are kept at the same height.

[0010] In this application, the diameter of the compressed air outlet is smaller than the diameter of the compressed air inlet, and there is a size difference at the compressed air outlet, which drives the wind turbine assembly to rotate at high speed. The air pressure can be balanced through the lower and upper air pressure relief outlets. After the pressurized air drives the pneumatic wheel assembly, it is divided into two parts. One part goes up to cool the upper ceramic bearing and then is discharged through multiple upper air pressure relief outlets. The other part goes down and enters the cavity through four lower air pressure relief outlets to cool the lower ceramic bearing and blow away the dust on the atomizing wheel.

[0011] Beneficial effects: In this utility model, the design of the pressurization component of the wind-driven high-speed atomizer makes the compressed air outlet diameter smaller than the compressed air inlet diameter. By utilizing the difference in diameter, the pressure of the compressed air can be effectively increased, thereby driving the wind turbine assembly to rotate at high speed, improving the utilization rate of compressed air and enhancing the atomization effect. In this invention, the lower and upper air pressure relief outlets 9 of the wind-driven high-speed atomizer ensure air pressure balance within the cavity. The upper air pressure relief outlets are evenly distributed, allowing the upward-flowing air to cool the upper ceramic bearings before being discharged, thus extending the service life of the ceramic bearings.

Four lower air pressure relief outlets 8 are provided, evenly distributed at the bottom end of the lower bearing housing 3. These outlets are connected to the air cavity and the air chamber, respectively, and are at the same height as the lower ceramic bearing 2. A portion of the descending air enters the air chamber through the four lower air pressure relief outlets 8 to cool the lower ceramic bearing 2, while simultaneously cleaning the dust from the atomizing wheel.
