Description

Technical Field

[0001] This utility model relates to the field of marine sewage treatment technology, and more specifically, to a multi-stage cleaning device for marine domestic sewage. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. For example, patent application number CN201520438521.5 proposes a marine wastewater treatment system, including a wastewater tank installed on the ship; a toilet installed on the ship; a wastewater pipe connecting the toilet and the wastewater tank; a vent pipe vertically installed on the top surface of the wastewater tank and connected to the tank; a pulverizing pump; a first drain pipe connecting the wastewater tank and the inlet of the pulverizing pump; a three-way ball valve with three ports; a second drain pipe connecting the outlet of the pulverizing pump and the first port of the three-way ball valve; a third drain pipe connecting the second port of the three-way ball valve and the deck drain outlet; and a fourth drain pipe connecting the third port of the three-way ball valve and the hull drain outlet. This utility model can store domestic wastewater on board and discharge it overboard after environmentally treated wastewater.

[0003] However, the above-mentioned technical solutions have limitations in use. Due to the limited capacity of the sewage tank, sewage cannot be treated when the ship is far from the shore and no permitted discharge area can be found, causing inconvenience to navigation. In addition, most marine sewage treatment devices have simple structures, poor treatment effects, and are prone to blockage during use, making maintenance troublesome. Therefore, we have made improvements and proposed a multi-stage cleaning device for marine domestic sewage. Utility Model Content

All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of this utility model are within the protection scope of this utility model.

[0038] Example

[0039] like Figure 1-10 As shown, a multi-stage cleaning device for marine domestic sewage includes a box 1, a crushing mechanism 2 is provided at the top of the box 1, a reaction mechanism 3 is provided at the lower end of the crushing mechanism 2 and inside the box 1, a second filter component 4 and an aeration component 6 are respectively connected to the upper and lower ends of one side of the reaction mechanism 3, and a compression component 5 is connected to the bottom end of the reaction mechanism 3.

[0040] The crushing mechanism 2 includes a crushing pump 201, a first compressor 202, a feeding assembly 203, and a first filter assembly 204. The crushing pump 201 is fixedly installed on the upper end of the first filter assembly 204. A first unblocking assembly 206 is provided at the bottom end of the first filter assembly 204.

[0043] The aeration assembly 6 includes an aeration box 601 and an aerator 603. A baffle 602 is provided inside the aeration box 601, and an aeration pipe 604 is fixedly connected to the output end of the aerator 603.

[0044] In a specific configuration, the first filter assembly 204 includes a sealed box 2041 and a fixing block 2042. The fixing block 2042 is fixedly installed inside the sealed box 2041. A first filter plate 2043 is fixedly installed at the bottom of the fixing block 2042. A first limiting plate 2044 is fixedly installed on the inner side of the upper end of the fixing block 2042. A first compressor 202 is fixedly installed at one end of the sealed box 2041.

[0045] In this embodiment, inclined surfaces are provided on both sides of the upper end of the fixing block 2042, and the first limiting plate 2044 is installed inside the inclined surfaces. By setting the crushing pump 201, the objects mixed in the sewage can be crushed, and then filtered by the first filter plate 2043, which can initially remove impurities from the water.

[0046] In a specific configuration, the feeding assembly 203 includes a fixed box 2031 and an electric push rod 2032. The fixed box 2031 is fixedly installed at the end of the sealed box 2041 away from the first compressor 202. The electric push rod 2032 is fixedly installed inside the fixed box 2031. A push block 2033 is fixedly connected to the output end of the electric push rod 2032. A limiting groove 2034 corresponding to the first limiting plate 2044 is provided on the upper end of the push block 2033.

[0047] The electric push rod 2032 drives the push block 2033 to move, which can push the impurities on the first filter plate 2043 into the first compressor 202 for compression. By setting a through groove 205 at the lower end of the first compressor 202, the water squeezed out during the compression process can flow back into the sealed box 2041 and enter the next treatment step along with the pre-filtered wastewater. During the movement of the push block 2033, the inner wall of the push block 2033 slides relative to the first limiting plate 2044, which can guide and limit the push block 2033.

[0048] In a specific configuration, the first unblocking component 206 includes a first cylinder 2061 and a mounting plate 2062. The first cylinder 2061 is fixedly installed inside the bottom of the sealing box 2041. The output end of the first cylinder 2061 is fixedly connected to the mounting plate 2062. A first blocking block 2063 is fixedly connected to the upper surface of the mounting plate 2062. The end of the mounting plate 2062 away from the first cylinder 2061 is movably sleeved outside the body of the limiting rod 2064. The limiting rod 2064 is fixedly installed inside the sealing box 2041. The bottom end of the first compressor 202 is provided with a through groove 205 that communicates with the bottom end of the sealing box 2041.

[0049] In this embodiment, the first blocking block 2063 corresponds to the filter hole in the first filter plate 2043. The first cylinder 2061 can drive the mounting plate 2062 and the first blocking block 2063 to move up and down. When the first blocking block 2063 moves upward, it can block the filter hole of the first filter plate 2043 and push the debris inside the filter hole upward. At this time, the electric push rod 2032 is activated, so that the bottom end of the push block 2033 is attached to the upper surface of the first filter plate 2043, thereby pushing all the debris into the first compressor 202. The first blocking block 2063 is located below the first filter plate 2043 in the initial state to ensure normal sewage flow. The two ends of the mounting plate 2062 are respectively attached to the inner wall of the sealing box 2041. By setting the limiting rod 2064, the mounting plate 2062 and the first blocking block 2063 can be limited during the movement to prevent the end of the mounting plate 2062 away from the first cylinder 2061 from tilting.

[0050] In the specific setup, the reaction tank 301 is fixedly connected to the bottom of the sealed box 2041. Two feeding pipes 306 are installed through the inside of the reaction tank 301. A storage tank 305 is fixedly connected to the top of the feeding pipe 306. The stirring assembly 302 includes a connecting rod 3021 and a motor 3026. The output end of the motor 3026 is fixedly connected to the connecting rod 3021. A spiral blade 3024 is fixedly connected to the top of the connecting rod 3021. A stirring plate 3022 is fixedly connected to the middle of the connecting rod 3021. A through hole 3023 is opened inside the stirring plate 3022. A roller 3025 is rotatably connected to the lower end of the stirring plate 3022. A push rod 304 is fixedly connected to the lower end of the connecting rod 3021. The push rod 304 is in contact with the inner wall of the bottom of the reaction tank 301.

[0051] In this embodiment, an appropriate amount of coagulant is added to the storage tank 305 according to the actual situation, and the coagulant is introduced into the reaction tank 301 through the feeding pipe 306. The feeding pipe 306 has several slots on the side near the connecting rod 3021, which can stir and mix the coagulant during the rotation of the stirring plate 3022. By setting through holes 3023 inside the stirring plate 3022, the mixing rate of sewage and additives can be accelerated. The floating mixture flows from the first outlet 307 to the second filter assembly 4 for filtration. The sediment at the bottom of the reaction tank 301 is pushed to the compression assembly 5 for pressing through the push rod 304. The treated water flows to the aeration assembly 6 for aeration through the second outlet 308.

[0052] In a specific configuration, the second unblocking component 303 includes a support plate 3031 and a movable block 3033. The support plate 3031 is fixedly installed on the inner wall of the reaction tank 301. A movable groove 3032 is provided at one end of the support plate 3031 away from the inner wall of the reaction tank 301. The movable block 3033 is movably disposed inside the movable groove 3032. A second blocking block 3037 is fixedly connected to the bottom end of the movable block 3033. A support rod 3034 is fixedly connected to the upper surface of the second blocking block 3037 and located on one side of the movable block 3033. A spring 3035 is sleeved on the upper end of the support rod 3034. The two ends of the spring 3035 are fixedly connected to the support rod 3034 and the support plate 3031, respectively. A second limiting plate 3036 is fixedly connected to one side of the lower end of the movable block 3033. The second limiting plate 3036 is movably sleeved on the outside of the support rod 3034. A roller 3025 is rotatably connected to the movable block 3033.

[0053] In this embodiment, when the roller 3025 is not in contact with the movable block 3033, the support rod 3034, the second blocking block 3037, and the movable block 3033 move upward under the drive of the spring 3035, so that the second blocking block 3037 presses tightly against the lower surface of the support plate 3031. During setup, the stirring plate 3022 and the push rod 304 are staggered, and the bottom of the second blocking block 3037 is higher than the push rod 304, causing the push rod 304 to rotate under the drive of the connecting rod 3021, thereby pushing the precipitate out of the reaction tank 301. When the roller 3025 is not in contact with the movable block 3033, the support rod 3034, the second blocking block 3037, and the movable block 3033 move upward under the drive of the spring 3035, so that the second blocking block 3037 presses tightly against the lower surface of the support plate 3031. When the roller 3025 rotates to the movable block 3033, it comes into contact with the movable block 3033 and rolls. As the stirring plate 3022 moves, the movable block 3033 causes the second block 3037 and the support rod 3034 to move downwards. The spring 3035 contracts until the second block 3037 enters the groove at the bottom of the reaction tank 301, which pushes the sediment in the groove downwards to prevent the groove from being blocked. Then, the spring 3035 drives the support rod 3034 and the second block 3037 to reset.

[0054] In the specific setup, the first outlet 307 and the second outlet 308 are fixedly connected to the upper and lower ends of one side of the reaction tank 301, respectively. The ends of the first outlet 307 and the second outlet 308 away from the reaction tank 301 are fixedly connected to the filter tank 401 and the aeration box 601, respectively. A control rod 402 is fixedly connected to the middle of the second filter plate 405. A sealing cover 403 is movably connected to the upper end of the control rod 402. The sealing cover 403 is fixedly installed on the top of the filter tank 401. A third outlet 406 is fixedly connected to the bottom of the filter tank 401. The bottom of the third outlet 406 is fixedly connected to the aeration box 601.

[0055] In this embodiment, the second filter plate 405 uses resin as the adsorption material, which has the advantages of good adsorption performance and easy regeneration and reuse. By setting threads on the outer peripheral surface of the second filter plate 405 corresponding to the threaded groove 404, it is easy to install and disassemble the second filter plate 405 and facilitate subsequent cleaning. Three layers of second filter plates 405 are set inside the filter tank 401, which can adsorb and filter the suspended matter generated inside the reaction tank 301. The filtered water flows into the aeration box 601 through the third outlet 406.

[0056] In a specific configuration, the compression assembly 5 includes a first connecting pipe 501 and a second compressor 502. The second compressor 502 is connected to the bottom of the reaction tank 301 through the first connecting pipe 501. A second connecting pipe 503 is fixedly connected to one side of the second compressor 502. The end of the second connecting pipe 503 away from the second compressor 502 is fixedly connected to the second outlet 308.

[0057] In the specific setup, the aerator 603 is fixedly installed on one side of the aeration box 601, the aeration pipe 604 passes through the aeration box 601 and is fixedly connected to the baffle 602, and the bottom of the aeration box 601 is fixedly connected to the fourth outlet 605 that passes through the box body 1.

[0058] In this embodiment, the sediment inside the reaction tank 301 is compressed by the second compressor 502. The water generated during the compression process flows into the aeration tank 601 through the second connecting pipe 503, along with the treated water inside the reaction tank 301. By setting several baffles 602 inside the aeration tank 601 and laying aeration pipes 604 on both sides of the baffles 602, the reaction time of the wastewater inside the aeration tank 601 can be extended, thereby improving the purification effect.

[0059] The working principle of this multi-stage cleaning device for marine sewage:

[0060] In operation, wastewater first enters the pulverizing pump 201, which pulverizes any substances mixed in the wastewater. The pulverized substances then enter the sealed chamber 2041 and undergo preliminary filtration through the first filter plate 2043. After a period of time, the first cylinder 2061 and the electric push rod 2032 are activated. The first cylinder 2061 moves the mounting plate 2062 and the first block 2063 upwards, causing the first block 2063 to enter the first filter plate 2043 and push the substances adhering to the inner wall of the first filter plate 2043 upwards. Subsequently, the electric push rod 2032 moves the push block 2033 towards the first compressor 202, pushing the substances on the upper surface of the first filter plate 2043 upwards. Inside the first compressor 202, the first compressor 202 is started to compress water. Then, the push block 2033 and the first block 2063 are reset. The water produced by compression flows through the channel 205 into the sealed box 2041. Next, coagulant is added into the reaction tank 301, allowing the coagulant to react with the wastewater. Simultaneously, the motor 3026 is started, driving the connecting rod 3021 and the push rod 304 to rotate, which in turn drives the spiral blades 3024 and the stirring plate 3022 to rotate. This causes the wastewater inside the sealed box 2041 to flow into the reaction tank 301. The stirring plate 3022 thoroughly mixes the wastewater and coagulant. During the mixing process, some substances settle to the bottom of the reaction tank 301, and are then released by the push rod 3024. 4. The sediment is collected and pushed into the slot at the bottom of the reaction tank 301. When the stirring plate 3022 rotates to the movable block 3033, the roller 3025 contacts the inclined surface of the movable block 3033 and rotates. As the stirring plate 3022 rotates, the movable block 3033 is pressed downward, thereby driving the second block 3037 and the support rod 3034 to move downward, causing the spring 3035 to contract until the second block 3037 enters the slot at the bottom of the reaction tank 301, pushing the sediment in the slot downward and preventing the slot from becoming blocked. When the roller 3025 leaves the movable block 3033, the spring 3035, under its own elastic force, drives the support rod 3034 to move upward, thereby driving the second block 3037 and the movable block 3034 to move downward. 3033 moves upward until the lower end of the movable block 3033 is pressed tightly against the lower surface of the support plate 3031. The suspended matter generated by the reaction flows from the first outlet 307 into the filter tank 401, and is adsorbed and filtered by the three layers of second filter plates 405. After filtration, it flows into the aeration box 601. The water that flows out after being compressed by the second compressor 502 flows through the second connecting pipe 503 into the second outlet 308, and then into the aeration box 601. The aerator 603 is started, so that the gas enters the aeration box 601 from the aeration pipe 604 and finally flows out from the fourth outlet 605. With the setting of the baffle 602, the sewage flows in an S-shape inside the aeration box 601, so that it can fully react with the gas and improve the treatment effect of sewage.

[0061] It should be noted that the specific models and specifications of the crushing pump 201, the first compressor 202, the electric push rod 2032, the first cylinder 2061, the motor 3026, the second compressor 502, and the aerator 603 are determined according to the actual usage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
