Description

Technical Field

[0001] This utility model relates to the field of ship painting technology, and in particular to a ship pressure spraying machine. Background Technology

[0002] Marine pressure sprayers are used to uniformly spray paint, varnish, or other liquid materials onto the surface of a ship in an atomized form. Traditional pressure sprayers typically include basic components such as an inlet pipe, pressure pump, outlet pipe, and spray gun. High pressure is generated by compressed air or a hydraulic system, causing the paint to be sprayed at high speed from the nozzle and adhere to the target surface. During spraying, a filter is needed to filter the paint. Traditional filters are usually flat, and the central area often experiences high negative pressure during operation, leading to filter deformation or damage, reducing filtration efficiency and durability. Especially under high-pressure environments, the structural strength of the filter is insufficient, making it prone to failure. Flat filter screens have a relatively small filtration area, especially when handling high-viscosity paints or paints containing many impurities; the screen is prone to rapid clogging, requiring frequent cleaning or replacement, increasing maintenance costs and operational complexity. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a ship pressure spraying machine that improves the stability and filtration effect of the filter screen and reduces the frequency of cleaning or replacement of the filter screen.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] A marine pressure spraying machine includes a feed pipe, a pressure pump, a discharge pipe, and a mobile trolley. The pressure pump is mounted on the mobile trolley. The feed end of the pressure pump is connected to the feed pipe, and the discharge end of the pressure pump is connected to the discharge pipe. A filter cover is provided at the end of the feed pipe. The filter cover includes a housing, a spherical filter screen, and a corrugated filter screen. The corrugated filter screen is located at the bottom of the housing, and the spherical filter screen is located above the corrugated filter screen. The pore size of the spherical filter screen is smaller than that of the corrugated filter screen.

[0006] Furthermore, a first support frame is provided above the spherical filter screen, and the first support frame is connected to the filter cover.

[0007] Furthermore, a second support frame is provided above the wavy filter screen, and the second support frame is connected to the filter cover.

[0008] Furthermore, the cross-section of the wavy filter screen is wavy.

[0009] Furthermore, the filter cover is connected to a clamp via a connecting rod, the clamp being used to hold it against the side wall of the paint bucket.

[0010] Furthermore, the clamp includes a base, a clamping plate, and a spring. The clamping plate is rotatably connected to the base. One end of the spring is connected to the base, and the other end is connected to the clamping plate. The base is connected to a connecting rod.

[0011] Furthermore, the base is provided with a vibrator, which is a vibration motor.

[0012] The beneficial effects of this invention are as follows: The paint undergoes initial filtration through a corrugated filter to remove larger particles of impurities, followed by fine filtration through a spherical filter with smaller pores. This ensures that the paint entering the spraying machine is purer, reducing the risk of clogging and improving spraying quality and equipment lifespan. The corrugated filter design increases the filtration area, enabling more effective impurity capture compared to traditional flat filters and reducing the likelihood of clogging. The reduced negative pressure difference between the center and edges of the spherical filter prevents deformation or damage caused by high negative pressure in localized areas, improving filtration efficiency and enhancing filter durability.

[0019] Example 1

[0020] Please refer to the attached document. Figure 1 This application provides a marine pressure spraying machine, including an inlet pipe 1, a pressure pump 2, an outlet pipe 3, and a mobile trolley 4. The pressure pump 2 is mounted on the mobile trolley 4. The inlet end of the pressure pump 2 is connected to the inlet pipe 1, and the outlet end of the pressure pump 2 is connected to the outlet pipe 3. A filter cover 5 is provided at the end of the inlet pipe 1. The filter cover 5 includes a housing 6, a spherical filter screen 7, and a corrugated filter screen 8. The corrugated filter screen 8 is located at the bottom of the housing, and the spherical filter screen 7 is located above the corrugated filter screen 8. The aperture of the spherical filter screen 7 is smaller than the aperture of the corrugated filter screen 8. The mobile trolley 4 can be easily moved to the spraying position. The end of the inlet pipe 1 is placed into the paint bucket. The high pressure generated by the pressure pump 2 draws away the paint and discharges it from the outlet pipe 3. The outlet pipe 3 is used to connect to the spray nozzle, thereby atomizing and spraying the paint. A filter cover 5 is installed at the end of the feed pipe 1 to perform preliminary filtration of the paint, reducing dust and impurities entering the sprayer. The filter cover 5 includes a housing 6, a spherical filter screen 7, and a corrugated filter screen 8. The paint flows through the corrugated filter screen 8 first, and then through the spherical filter screen 7. Within the same inner diameter of the filter cover 5, the corrugated filter screen 8 has a larger filtration area, resulting in better filtration. After the first filtration by the corrugated filter screen 8, the paint undergoes a second filtration using the spherical filter screen 7. Dust and impurities are intercepted at the bottom of the spherical filter screen 7 as they pass through. Due to the downward curve in the middle of the spherical filter screen 7, the negative pressure difference between the center and the edge is small, which is beneficial for filtering dust and impurities. Furthermore, the arched structure of the spherical filter screen 7 enhances its strength.

[0021] Specifically, a first support frame 9 is provided above the spherical filter screen 7, and the first support frame 9 is connected to the filter cover 5. The outer periphery of the first support frame 9 is connected to the filter cover 5, and the spherical filter screen 7 is supported from above by the first support frame 9, thereby improving the stability of the spherical filter screen 7.

[0022] Specifically, a second support frame 10 is provided above the corrugated filter screen 8, and the second support frame 10 is connected to the filter cover 5. The outer periphery of the second support frame 10 is connected to the filter cover 5, and the corrugated filter screen 8 is supported from above by the second support frame 10, thereby improving the stability of the corrugated filter screen 8.

[0023] Specifically, the cross-section of the wavy filter 8 is wavy. The wavy filter 8 is composed of several concentric annular filters, and the cross-section of the annular filters is C-shaped, so that the cross-section of the wavy filter 8 composed of several annular filters is wavy.

[0024] Example 2

[0025] Please refer to the attached document. Figure 2 The difference between this embodiment and Embodiment 1 is that the filter cover 5 is connected to the clamp 12 via a connecting rod 11, and the clamp 12 is used to clamp the side wall of the paint bucket. One end of the connecting rod 11 is connected to the filter cover 5, and the other end is connected to the clamp 12. Clamping the clamp 12 to the side wall of the paint bucket can improve the stability of the filter cover 5 during movement.

[0026] Specifically, the clamp 12 includes a base 13, a clamping plate 14, and a spring 15. The clamping plate 14 is rotatably connected to the base 13. One end of the spring 15 is connected to the base 13, and the other end is connected to the clamping plate 14. The base 13 is connected to the connecting rod 11. Under the action of the spring 15, the clamping plate 14 has a driving force to rotate to the base 13, clamping the side wall of the paint bucket between the clamping plate 14 and the base 13. The base 13 is then connected to the connecting rod 11, thereby fixing the filter cover 5.

[0027] Optionally, a vibrator 16, which is a vibration motor, is provided on the base 13. When the vibration motor vibrates, it drives the connecting rod 11 and the filter cover 5 at the bottom of the connecting rod 11 to vibrate. Under the action of vibration, dust and impurities at the bottom of the spherical filter screen 7 are detached from the spherical filter screen 7. Since the outer periphery of the spherical filter screen 7 is curved upward, the detached impurities tend to move along the edge when moving upward, thereby promoting the movement of impurities at the bottom of the spherical filter screen 7 towards the edge and reducing the clogging of the spherical filter screen 7. At the same time, the vibration also causes impurities on the corrugated filter screen 8 to fall to the top, thereby preventing the sides and bottom of the corrugated filter screen 8 from being blocked and ensuring that the coating can be smoothly extracted.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
