A high-pressure water jet rust removal wastewater recovery device

Abstract

This invention provides an ultra-high pressure water jet rust removal wastewater recovery device. During operation, the inlet pump draws wastewater splashed during the cleaning process through the inlet pipe. The wastewater flows to the collection pipe and the annular channel on the annular disc. The drive mechanism drives the rotating frame to rotate several mounting cylinders, and in conjunction with the linkage mechanism, drives the magnetic rods to move relative to the mounting cylinders. As the mounting cylinders rotate to the collection pipe, the magnetic rods move towards the inside of the mounting cylinders. Under the action of magnetic force, rust in the water adheres to the mounting cylinders. As the rust mounting cylinders rotate to the waste box, under the action of the linkage mechanism, the magnetic rods move towards the outside of the mounting cylinders. After the magnetic rods move away from the annular channel, the rust falls into the waste box under gravity, thus removing rust from the wastewater. In conjunction with the filter assembly, the water is filtered, and the filtered water is stored in a storage tank, which can effectively prevent rust from adhering to the filter screen and facilitate the smooth operation of wastewater collection and jet rust removal.

Description

Technical Field

[0001] This invention relates to the field of dock cleaning equipment, specifically to an ultra-high pressure water jet rust removal wastewater recovery device. Background Technology

[0002] After a period of use at sea, various ships and drilling platforms develop a thick layer of marine life on their hulls, and the hull plates are corroded by seawater, gradually rusting. Currently, most shipyards use dockside trucks with ultra-high pressure jet devices to remove rust using high-pressure water jets. However, the wastewater generated during the rust removal process often splashes into the dock and flows into the sea when seawater is injected, causing environmental pollution. Moreover, this wastewater is not fully utilized, wasting water resources. To improve water utilization, a collection tray is often installed at the nozzle to collect the wastewater, and a filter screen is used to filter the wastewater before it is used in conjunction with the ultra-high pressure jet device for rust removal. However, after prolonged use, rust and other stains easily adhere to the filter screen, causing the mesh to become clogged. This leads to wastewater overflow from the collection tray and affects the water pressure of the high-pressure jet device, thus adversely affecting wastewater collection and rust removal, resulting in poor overall wastewater collection and rust removal efficiency.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] During operation, the inlet pump draws up the wastewater splashed during the cleaning process through the inlet pipe. The wastewater flows to the collection pipe and the annular channel on the annular disc. The drive mechanism drives the rotating frame to rotate several mounting cylinders, and in conjunction with the linkage mechanism, drives the magnetic rods to move relative to the mounting cylinders. As the mounting cylinders rotate to the collection pipe, the magnetic rods move inward. Under the action of magnetic force, rust in the water adheres to the mounting cylinders. As the rust mounting cylinders rotate to the waste box, under the action of the linkage mechanism, the magnetic rods move outward. Due to the limiting effect of the inner wall of the annular channel and the friction of the mounting cylinder surface, the rust cannot move with the magnetic rods. After the magnetic rods move away from the annular channel, the rust falls into the waste box under gravity, thus removing rust from the wastewater. In conjunction with the filter assembly, the water is filtered and stored in the storage tank. This effectively prevents rust from adhering to the filter screen, facilitating the smooth operation of wastewater collection and jet rust removal. Attached Figure Description

Detailed Implementation

[0030] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0031] Example 1:

[0032] Reference Figures 1 to 6 This invention provides an ultra-high pressure water jet rust removal wastewater recovery device, comprising:

[0033] The container 1 is equipped with a manifold 2 and a water storage tank 3. A water inlet pipe 21 is connected to the manifold 2, and a water inlet pump 22 is installed on the water inlet pipe 21. A vacuum pump 31 is installed on the water storage tank 3.

[0034] An annular disc 4 is inclined relative to the water storage tank 3. An annular channel 41 is provided on the annular disc 4. The lower end of the annular channel 41 is connected to the water storage tank 3. The upper end of the annular channel 41 is provided with a discharge port 42. A waste frame 5 is movably provided on the box body 1. The waste frame 5 is located below the discharge port 42 and is used to receive the waste at the discharge port 42.

[0035] Rotating frame 6 is rotatably mounted on annular channel 41. Several mounting cylinders 61 are provided on rotating frame 6, and a magnetic rod 62 is movably mounted on each mounting cylinder 61.

[0036] Drive mechanism 11 is connected to rotating frame 6 and can drive rotating frame 6 to rotate;

[0037] Linkage mechanism 7 is connected to several magnetic rods 62 and can drive several magnetic rods 62 to move according to the rotation process of rotating frame 6 so that the magnetic rods 62 can extend out of the lower end of the annular disk 4 and retract at the upper end of the annular disk 4.

[0038] The filter assembly 8 is used to connect the lower end of the annular channel 41 to the water storage tank 3 and to filter the water.

[0039] Working principle: During operation, the inlet pump 22 draws out the wastewater splashed during the cleaning process through the inlet pipe 21. The wastewater flows to the annular channel 41 on the collector pipe 2 and the annular disc 4. The drive mechanism 11 drives the rotating frame 6 to rotate several mounting cylinders 61, and in conjunction with the linkage mechanism 7, drives the magnetic rod 62 to move relative to the mounting cylinders 61. As the mounting cylinders 61 rotate to the collector pipe 2, the magnetic rod 62 moves towards the inside of the mounting cylinders 61. Under the action of magnetic force, rust in the water adheres to the mounting cylinders 61. The rust-covered mounting cylinders 61 rotate to the waste frame 5. During the process, under the action of the linkage mechanism 7, the magnetic rod 62 moves towards the outside of the mounting cylinder 61. Due to the limiting effect of the inner wall of the annular channel 41 and the friction force on the surface of the mounting cylinder 61, the rust cannot move with the magnetic rod 62. After the magnetic rod 62 moves away from the annular channel 41, the rust falls into the waste frame 5 under gravity, which plays the role of removing rust from the sewage. It also works with the filter assembly 8 to filter the water and store the filtered water in the water storage tank 3. This can effectively prevent rust from adhering to the filter screen and facilitate the smooth progress of sewage collection and jet rust removal.

[0040] Specifically, the linkage mechanism 7 includes a spring 71, a slider 72, and a limiting ring 73. The spring 71 is mounted on the mounting cylinder 61, the slider 72 is movably mounted on the mounting cylinder 61 and connected to the magnetic rod 62, and the limiting ring 73 is mounted on the housing 1. The spring 71 can push the slider 72 to drive the slider 72 to abut against the inner side of the limiting ring 73.

[0041] Specifically, the central axis of the limiting ring 73 is located below the rotation axis of the rotating frame 6.

[0042] Specifically, the slider 72 is rotatably provided with a limiting wheel 721 that can abut against the limiting ring 73.

[0043] During the rotation of the rotating frame 6 driven by the drive mechanism 11, the spring 71 drives the slider 72 to move so that the limiting wheel 721 abuts against the limiting ring 73. This allows the slider 72 to adjust the position of the magnetic rod 62 relative to the mounting cylinder 61 according to the contour of the limiting ring 73. As the mounting cylinder 61 rotates downwards to the collection pipe 2, the magnetic rod 62 extends into the interior of the mounting cylinder 61. Under the action of magnetic force, it attracts rust from the water to the surface of the mounting cylinder 61. As the rotating frame 6 drives the mounting cylinder 61 to the waste box 5, the magnetic rod 62 moves away from the annular channel 41. Due to the limiting effect of the inner wall of the annular channel 41 and the friction of the surface of the mounting cylinder 61, the rust cannot move with the magnetic rod 62. After the magnetic rod 62 moves away from the annular channel 41, the rust falls into the waste box 5 under gravity, thus removing rust from the sewage. The waste box 5 is mounted on the box 1 with a drawer-type structure. It can be pulled out as needed for the treatment of rust and stains.

[0044] Specifically, the drive mechanism 11 is a servo motor, which is connected to the rotating frame 6 and can drive the rotating frame 6 to rotate.

[0045] Example 2:

[0046] Reference Figures 1 to 6 In conjunction with the technical solution of Embodiment 1, in this embodiment, the filter assembly 8 includes a first filter tube 81, a second filter tube 82, a water pumping pipe 83, an exhaust pipe 84, a sewage pipe 85, a water supply pipe 86, a first valve 87, and a second valve 88. A first filter screen is provided on the first filter tube 81, and a second filter screen is provided on the second filter tube 82. The water pumping pipe 83 is connected to the water storage tank 3, and the water supply pipe 86 is connected to the manifold 2. The first valve 87 is connected to the first filter tube 81, the second filter tube 82, the water supply pipe 86, and the sewage pipe 85 respectively and can adjust the connection status of the four pipes. The exhaust pipe 84 is connected to the exhaust end of the vacuum pump 31. The second valve 88 is connected to the first filter tube 81, the second filter tube 82, the water pumping pipe 83, and the exhaust pipe 84 respectively and can adjust the connection status of the four pipes. The sewage pipe 85 is used to guide waste to the waste frame 5.

[0047] Working principle:

[0048] Vacuum pump 31 draws air from water storage tank 3 and discharges it through exhaust pipe 84. Second valve 88 connects first filter pipe 81 and water suction pipe 83, and second filter pipe 82 and exhaust pipe 84. First valve 87 connects first filter pipe 81 and water supply pipe 86, and second filter pipe 82 and sewage discharge pipe 85. Under negative pressure, sewage from collection pipe 2 flows to water storage tank 3 through water supply pipe 86, first filter pipe 81, and water suction pipe 83. During this process, the first filter screen at first filter pipe 81 filters the water. Gas discharged from exhaust pipe 84 is discharged to waste frame 5 through second filter pipe 82 and sewage discharge pipe 85. The flowing gas washes the dirt on the second filter screen into waste frame 5. In other words, during the pumping process, the first filter screen filters the water... During filtration, the gas discharged from the exhaust pipe 84 washes the second filter screen. When a large amount of dirt accumulates on the first filter screen, the second filter pipe 82 and the water pumping pipe 83 are connected through the second valve 88, and the first filter pipe 81 and the exhaust pipe 84 are connected. The second filter pipe 82 and the water pumping pipe 83 are connected through the first valve 87, and the first filter pipe 81 and the sewage discharge pipe 85 are connected. Wastewater flows through the second filter screen into the water storage tank 3, and the gas discharged from the exhaust pipe 84 washes the first filter screen. This allows for the washing of another filter screen while the current filter screen is filtering, facilitating filter screen replacement, keeping the surface of the filter screen clean, preventing filter screen clogging, and ensuring the normal operation of wastewater collection and jet rust removal. Both the first valve 87 and the second valve 88 can be adjusted using solenoid valves and a control panel.

[0049] Specifically, the mounting cylinder 61 is made of plastic and has a smooth surface.

[0050] Specifically, a water supply pipe 32 controlled by a valve is connected to the water storage tank 3, and a water tank 9 is connected to the water supply pipe 32.

[0051] Specifically, a water spray pipe 91 is connected to the water tank 9, and a nozzle 92 is connected to the water spray pipe 91.

[0052] The valve can be opened to divert water from storage tank 3 to water tank 9, which can then be used with nozzle 92 for rust removal.

[0053] Specifically, the nozzle 92 is equipped with a collection tray 93 for collecting wastewater, and the collection tray 93 has collection ports around its perimeter that are connected to the water inlet pipe 21. The collection tray 93 is connected to the housing 1 via a robotic arm, which can drive the collection tray 93 to move and rotate to fit the bottom of the hull for rust removal.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
