A spray system for spraying parts

Abstract

The present application discloses a spraying system for parts spraying, which is designed for efficient and uniform treatment (such as cleaning, cooling, etc.) of parts. The core includes a spraying chamber and a built-in spraying assembly. The assembly is composed of a water tank (located under the chamber), a water pump, a connecting pipe (including a vertical part and a bottom horizontal part), and a C-shaped spraying pipe. The water pump pumps the liquid in the water tank into the horizontal pipe through the connecting pipe, and then distributes it to the C-shaped spraying pipes arranged symmetrically around the spraying area. The spraying pipe includes a top part (universal nozzle), a middle part (fan-shaped nozzle), and a bottom part (spiral nozzle), ensuring full coverage of the parts from top to bottom. The spraying pipes can be arranged relatively or staggered, combined with optional opposite or staggered nozzle layout, effectively eliminating the spraying blind area and achieving high uniformity of the spraying area. The system structure is stable (optional support strip), the liquid can be recycled, and a high-efficiency and reliable parts processing solution is provided.

Description

Technical Field

[0001] This application relates to the field of spray technology, and more specifically to a spray system for spraying parts. Background Technology

[0002] In the fields of parts manufacturing, cleaning, and surface treatment, spray systems are widely used key equipment for rinsing, cleaning, cooling, or coating parts with treatment fluids. Existing spray systems, especially those dealing with parts with complex structures or requiring multi-angle cleaning, generally suffer from poor spraying effects. This is mainly reflected in the nozzle arrangement of the spray pipe: 1. Monotonous Nozzle Arrangement: Traditional spray systems typically arrange the same type of nozzles evenly along the entire spray pipe. This design ignores the differences in the types of contaminants, adhesion levels, and spray liquid impact force requirements that parts may face at different spatial locations within the spray area (such as top, sides, bottom, and recesses). 2. Monotonous and Ineffective Spraying Effect: A single type of nozzle can only provide a spraying effect with a fixed flow rate, pressure, spray angle, and coverage area. This leads to: Uneven Coverage: For parts with complex geometries, a single spray pattern cannot ensure that all surfaces, especially internal cavities, grooves, and dead corners, are effectively covered and rinsed. Some areas may be over-cleaned, while other critical areas may be under-cleaned. Low cleaning / treatment efficiency: The system cannot provide differentiated spray parameters (such as pressure, flow rate, and atomization degree) for different parts of the component (e.g., high-pressure rinsing for areas prone to residue, and uniform coverage for large flat surfaces), resulting in suboptimal overall cleaning or treatment effects and low efficiency. Poor adaptability: When handling parts of different sizes, shapes, or cleanliness requirements, a single spray mode system lacks flexibility and adaptability, making it difficult to meet diverse needs.

[0003] Therefore, there is an urgent need for a new type of spray system design that can significantly improve the uniformity, thoroughness and efficiency of spraying, the core of which lies in breaking through the limitations of the existing single nozzle setting of the spray pipe. Utility Model Content

[0004] To address the problem of poor spraying effect in existing spraying systems, this application provides a spraying system for spraying parts. The specific technical solution of this application is as follows:

[0005] A spraying system for spraying parts includes a spray chamber and a spraying assembly disposed on the spray chamber. The spraying assembly includes a water tank, a water pump, a connecting pipe, and several spray pipes. The water tank is disposed below the spray chamber, and the water pump is disposed on the water tank. The connecting pipe includes a vertical pipe section and a horizontal pipe section. The horizontal pipe section is disposed at the bottom of the spray chamber. One end of the vertical pipe section is connected to the horizontal pipe section, and the other end passes through the spray chamber and is connected to the water tank via the water pump. The spray pipes have a C-shaped structure and are disposed in the spray chamber and are respectively arranged on both sides of the horizontal pipe section to form a spraying area. The top, middle, and bottom of the spray pipes are respectively provided with nozzles facing the spraying area, and the types of nozzles at the top, middle, and bottom of the spray pipes are different.

[0006] Furthermore, a plurality of nozzles are provided in the middle of the spray pipe, and the nozzles are arranged vertically in the middle of the spray pipe.

[0007] Furthermore, the spray pipes on both sides of the horizontal pipe are arranged opposite each other, and the nozzle in the middle of the spray pipe is directly opposite the nozzle of the spray pipe on the other side.

[0008] Furthermore, the nozzle in the middle of the spray pipe is offset from the nozzle in the middle of the adjacent spray pipe.

[0009] Furthermore, the nozzle in the middle of the spray pipe is a fan-shaped nozzle.

[0010] Furthermore, a nozzle is provided at the top and bottom of the spray pipe, and the nozzle at the top and the nozzle at the bottom of the spray pipe are positioned facing each other.

[0011] Furthermore, the nozzle at the top of the spray pipe is a universal spray head.

[0012] Furthermore, the nozzle at the bottom of the spray pipe is a spiral nozzle.

[0013] Furthermore, the spray system also includes support bars, and the spray pipe is connected to the spray chamber through the support bars.

[0014] Compared with existing technologies, the beneficial effects of this application are as follows: The spraying system for spraying parts described in this application effectively overcomes the shortcomings of existing technologies and significantly improves the spraying effect by differentially configuring different types of nozzles at key positions of the spray pipe. Specifically, this is reflected in:

[0015] 1. Achieve three-dimensional differentiated spraying: Different types of nozzles are installed at the top, middle, and bottom of the spray pipe (for example, a high-flow, wide-angle nozzle can be used at the top to cover the upper surface of the part; a medium-pressure, specific-angle nozzle can be used in the middle to clean the sides of the main body; and a high-pressure, focused, or special-angle nozzle can be used at the bottom to flush the bottom of the part and the dead corners of the grooves). This design allows the spray liquid to provide the most suitable spray characteristics (such as pressure, flow rate, angle, and atomization degree) according to the different spatial positions of the part in the spray area.

[0016] 2. Significantly improves spray uniformity and coverage: For cleaning difficulties in different positions (top, middle, bottom, inside, outside) of parts, the differentiated nozzle combination can ensure that the spray liquid effectively covers the entire surface of the parts, especially complex structural areas and dead corners that are difficult to reach by traditional single nozzles, greatly reducing spray blind spots.

[0017] 3. Optimize cleaning / treatment efficiency and effectiveness: Different types of nozzles work together to:

[0018] Apply stronger impact to stubborn stains or areas prone to residue (such as with a bottom-mounted high-pressure nozzle).

[0019] Provides uniform and adequate coverage and wetting for large areas of flat or curved surfaces (e.g., top wide-angle nozzle).

[0020] Precise and gentle cleaning of specific angles or precision areas (such as nozzles at a specific angle in the center). This synergistic effect significantly improves overall cleanliness, surface finish quality, or cooling / coating effectiveness.

[0021] 4. Enhanced system adaptability and flexibility: By scientifically planning the types of nozzles at different positions, the system can better adapt to parts of different sizes, shapes and cleaning / treatment requirements, improving the equipment's versatility and the consistency of treatment results.

[0022] 5. Improve resource utilization efficiency: Precise differentiated spraying can reduce unnecessary liquid waste (such as using excessive flow in easily cleanable areas), and may reduce the consumption of water or chemical agents while ensuring effectiveness. Attached Figure Description

[0035] like Figures 1 to 6 As shown, a spraying system for spraying parts includes a spray chamber 1 and a spraying assembly 2 disposed on the spray chamber 1. The spraying assembly 2 includes a water tank 3, a water pump 4, a connecting pipe 5, and several spray pipes 6.

The connecting pipe 5 consists of a vertical pipe section 7 (DN50 stainless steel pipe, wrapped with a polyurethane insulation layer (anti-condensation)) and a horizontal pipe section 8 (DN80 annular manifold, with a mirror-polished inner wall (Ra≤0.8μm) to reduce pressure loss). Spray pipe 6: C-shaped structure, with straight pipes at the top, middle, and bottom, and an angle of 90 degrees between the middle and the top and bottom; made of 316L stainless steel, resistant to acid and alkali corrosion; matrix layout, with 13 pipes on each side of the horizontal pipe section 8, spaced 200mm apart (adjustable). The water tank 3 is located below the spray chamber 1, and the water pump 4 is located on the water tank 3. The connecting pipe 5 includes a vertical pipe section 7 and a horizontal pipe section 8.

The spray pipe 6 has a C-shaped structure and is arranged in the spray chamber 1 on both sides of the horizontal pipe section 8 to form the spray area 9. The top 1010, middle 11, and bottom 12 of the spray pipe 6 are respectively provided with nozzles 13 facing the spray area 9.
