Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for rust removal from ship hulls. Background Technology

[0002] As a core process for maintaining the structural strength of ships and preventing corrosion, hull rust removal inevitably generates a large amount of wastewater with complex components. If these pollutants are discharged directly without proper treatment, they will severely impact the aquatic ecosystem and accumulate through the food chain, posing a threat to human health.

[0003] A wastewater treatment device for ship hull rust removal refers to the efficient purification treatment of highly polluting wastewater generated during the ship rust removal process, so that it meets the discharge standards or reuse requirements.

[0004] During use, existing equipment suffers from the complexity of pollutants, and most existing treatment devices have limited functions, making it impossible to achieve synergistic and efficient treatment of multiple pollutants. The treated water quality is difficult to consistently meet national discharge standards. Direct discharge will affect the water body's self-purification capacity, further aggravate pollution, and ultimately harm human health. Therefore, we provide a wastewater treatment device for ship hull rust removal. Utility Model Content

[0005] The purpose of this utility model is to provide a wastewater treatment device for ship hull rust removal. Through the filtration and neutralization mechanisms, it solves the problem that existing equipment, due to the complex composition of pollutants, has a single function and cannot achieve synergistic and efficient treatment of multiple pollutants. The treated water quality is difficult to consistently meet national discharge standards. If discharged directly, it will affect the water body's self-purification capacity, further aggravate pollution, and ultimately harm human health.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a wastewater treatment device for rust removal from ship hulls, including a base, a number of support columns are fixedly connected to the bottom outer wall of the base, a treatment tank is fixedly connected to the inner wall of the base, and a filtration mechanism is provided on the inner wall of the treatment tank.

[0008] The filtration mechanism includes a fixed plate, the top outer wall of which is fixedly connected to the bottom outer wall of the treatment tank. A motor is fixedly connected to the outer wall of the fixed plate. The bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The outer wall of the rotating shaft is rotatably connected to the inner wall of the treatment tank. A fixed block is fixedly connected to the outer wall of the rotating shaft away from the motor. Several brushes are fixedly connected to the outer wall of the fixed block. A sliding groove is formed on the inner wall of the treatment tank. The inner wall of the sliding groove is slidably connected to the outer wall of the brush. A filter plate is fixedly connected to the inner wall of the treatment tank. A baffle is hinged to the outer wall of the treatment tank. A handle is fixedly connected to the outer wall of the baffle away from the treatment tank. Several bolts are threadedly connected to the inner wall of the treatment tank. A cover plate is threadedly connected to the outer wall of the bolts. The bottom outer wall of the cover plate is attached to the top outer wall of the treatment tank.

[0009] Furthermore, a water pump is fixedly connected to the top outer wall of the cover plate, and a water outlet pipe is fixedly connected to the output end of the water pump. The outer wall of the water outlet pipe is fixedly connected to the inner wall of the cover plate, and a water suction pipe is fixedly connected to the inner wall of the water pump. A second water pump is fixedly connected to the top outer wall of the cover plate, and a second water outlet pipe is fixedly connected to the output end of the water pump. The outer wall of the second water outlet pipe is fixedly connected to the inner wall of the cover plate, and a second water suction pipe is fixedly connected to the inner wall of the second water pump. A high-pressure nozzle is fixedly connected to the outer wall of the second water outlet pipe. A neutralization mechanism is provided on the inner wall of the treatment tank.

[0010] Furthermore, the neutralization mechanism includes several auxiliary blocks, the inner walls of which are fixedly connected to the outer wall of the rotating shaft.

[0011] Furthermore, the outer wall of the auxiliary block is fixedly connected with several support rods.

[0012] Furthermore, several stirring blades are fixedly connected to the outer walls of several of the support rods.

[0013] Furthermore, several fan blades are fixedly connected to the outer wall of the rotating shaft.

[0014] Furthermore, a dosing funnel is fixedly connected to the inner wall of the treatment tank, and a water dosing funnel is fixedly connected to the inner wall of the end of the treatment tank away from the dosing funnel.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a brush. First, a water pump is started to inject wastewater into the treatment tank. The wastewater flows to the filter plate, where it is filtered, leaving waste residue on the surface. Then, a motor is started, causing the rotating shaft to rotate. The rotating shaft then rotates the fixed block, which in turn rotates the brush, cleaning and pushing the waste residue. Water sprayed from a high-pressure nozzle pushes the waste residue to a baffle. Pulling the handle opens the baffle, allowing the waste residue to be removed. This effectively filters residue from the wastewater while preventing the filter plate from clogging and affecting wastewater filtration.

[0018] 2. This utility model incorporates a support rod, a rotating shaft that drives an auxiliary block to rotate, the auxiliary block in turn drives the support rod to rotate, and the support rod in turn drives the stirring blades to rotate. This allows the wastewater, chemicals, and clean water to be mixed. Simultaneously, the rotating shaft drives the fan blades to rotate, ensuring that the wastewater and chemicals react fully. This prevents incomplete reaction that could lead to the wastewater not being completely neutralized and thus polluting the soil and water bodies after discharge.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the operator first starts the water pump 212. The water pump 212 draws wastewater through the suction pipe 213, and then through the outlet pipe 213 into the treatment tank 102. The wastewater first flows to the filter plate 207, where it filters out impurities, leaving residue on its surface. Then, the motor 202 is started, causing the rotating shaft 203 to rotate. The rotating shaft 203 drives the fixed block 204 to rotate, which in turn drives the brush 205 to rotate and slide within the chute 206, cleaning and pushing the waste residue. Next, the second water pump 215 is started, drawing clean water through the suction pipe 217 and then through the outlet pipe 216 to the high-pressure nozzle 218. When the brush 205 pushes the waste residue to the nozzle of the high-pressure nozzle 218, it is filtered and treated by the high pressure. The water sprayed from nozzle 218 pushes the waste residue to baffle 208. Then, pull handle 209 to open baffle 208 and remove the waste residue, preventing filter plate 206 from clogging. The filtered wastewater flows to neutralization mechanism 3. At this time, chemicals are added to treatment tank 102 through dosing funnel 305, and clean water is added to treatment tank 102 through water dosing funnel 306. At the same time, the rotating shaft 203 drives auxiliary block 301 to rotate, which in turn drives support rod 302 to rotate. Support rod 302 drives stirring blade 303 to rotate, mixing the wastewater, chemicals, and clean water. Simultaneously, the rotating shaft 203 drives fan blade 304 to rotate, improving the mixing efficiency of wastewater, chemicals, and clean water, making the reaction more complete. When stirring is complete, the motor is turned off, and then valve 308 is turned to discharge the treated wastewater through drain pipe 307.
