Description

Technical Field

[0001] This utility model relates to the field of ship rust removal technology, specifically a ship water rust removal vacuum recovery device. Background Technology

[0002] Ships, as vital tools for water transportation and marine resource development, operate in complex marine environments. Their hulls are susceptible to corrosion from seawater, sea breezes, and salt spray. Corrosion not only reduces the structural strength of the hull and threatens navigational safety but also shortens the ship's lifespan and increases maintenance costs. Therefore, regular rust removal and maintenance are crucial.

[0003] The prior art discloses a device for treating and recycling waste residue from high-pressure water rust removal and cleaning of ships, with publication number CN210713120U. This recycling device can separate and recycle waste residue generated from high-pressure water rust removal and cleaning, effectively solving the problems mentioned in the background art. It includes a side-opening box with bases at the four corners of the bottom. A drain pipe for the rust removal and cleaning equipment runs through the top of the box from top to bottom. An air inlet for the suction pump of the rust removal and cleaning equipment is fixedly installed on the top of the box to the left of the drain pipe. A drain pipe is also provided on the bottom plate of the box, extending to the left side of the box. A waste residue basket is placed directly below the drain pipe. A lifting mechanism is located in the box to the right of the waste residue basket, with lifting lugs on the top of the fixing frame for cooperation with the lifting mechanism. A power distribution box for cooperation with the lifting mechanism is fixedly installed on the right side of the box. It is simple to operate, convenient to use, and suitable for various locations.

[0004] The aforementioned ship water rust removal vacuum recovery device can introduce the waste residue sucked by the rust removal and cleaning equipment into the tank for subsequent processing, and the drain pipe at the bottom is used to discharge the liquid in the waste residue. However, the aforementioned ship water rust removal vacuum recovery device does not have a gravity linkage separation mechanism, so it cannot perform solid-liquid separation for convenient recycling and processing. The effect during use is not good and needs to be improved. Utility Model Content

At the same time, the two are connected to ensure that the waste can fall into the interior of the conical centrifugal separator 301.

[0027] The connecting buffer assembly 4 includes a discharge pipe 401, a drain pipe 402, a support frame 403, a limiting ring plate 404, a surface reinforcing ring plate 405, and an inner elastic pad 406. The discharge pipe 401 is fixedly connected to the bottom of the hollow cylinder 308, the drain pipe 402 is fixedly connected to the bottom of the discharge pipe 401, the support frame 403 is fixedly connected to the inside right side of the collecting hopper 1, the limiting ring plate 404 is fixedly connected to the left side of the support frame 403, the surface reinforcing ring plate 405 is fixedly connected to the surface of the limiting ring plate 404, the inner elastic pad 406 is fixedly connected to the inside of the limiting ring plate 404, a placement ring plate is fixedly connected to the surface of the drain pipe 402, and a connecting strip 306 is fixedly connected to the top of the placement ring plate.

The waste liquid tank 206 is fixedly connected to the front of the collecting hopper 1. The liquid pump 205 is fixedly connected to the top of the waste liquid tank 206.

[0029] In use, the adsorption component 307 is attached to the side of the ship requiring rust removal. Then, the negative pressure fan 312 is activated to generate negative pressure suction. This suction is transmitted through the discharge connecting pipe 310 and the connecting pipe 309, creating a negative pressure environment within the pipes and generating vacuum suction. Simultaneously, a rust removal spray gun is installed inside the adsorption component 307. After being attached to the ship, rust removal is performed, and the suction draws the removed rust into the pipe. The rust residue and wastewater mixture generated during rust removal are sucked into the recovery pipe. A portion of the wastewater mixture flows through the discharge pipe 401 into the drain pipe 402, and then into the collection hopper 1. The right side of the collection hopper 1 is equipped with a support frame 403, a limiting ring plate 404, and a surface reinforcing ring plate 405, which support and buffer the drain pipe 402, increasing its service life. Most of the mixture and rust residue reach the inner wall of the discharge connecting pipe 310 and then fall into the conical centrifugal separator 301. In operation, the drive motor 305 can be started to drive the rotating rod 304 to rotate, which in turn drives the second gear 303 to rotate. The rotation of the second gear 303 drives the first gear 302 meshing with it to rotate, which in turn drives the conical centrifugal separator 301 to rotate. Due to the conical structure and high-speed rotation of the conical centrifugal separator 301, solid particles such as rust are thrown towards the inner wall of the separator under the action of centrifugal force and slide down the inner wall to the bottom liquid cylinder 201, and fall into the outer annular collection part of the outer ring of the liquid cylinder 201. The wastewater, under the combined action of centrifugal force and gravity, gathers towards the center of the separator and flows into the inner liquid collection cylinder in the center of the liquid cylinder 201, realizing automatic solid-liquid separation and collection. The effect is good in use. The discharge extraction pipe 202 extends to the inner liquid collection cylinder. In use, the liquid pump 205 can be started to generate negative pressure suction to adsorb the liquid and enter the interior of the waste liquid tank 206, and then discharge it through the discharge pipe 207, which can facilitate the treatment of the internal liquid after solid-liquid separation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
