Description

Technical Field

[0001] The present invention relates to the field of recycling and purification equipment, and particularly to a ship waste liquid recycling and purification device and method. Background Technique

[0002] After waste liquid is generated on a ship, it cannot be directly discharged into the water. Direct discharge into the water is likely to cause pollution. Moving the waste liquid to a sewage treatment plant through equipment wastes a lot of time, and a large amount of waste liquid cannot be collected and piled up on the ship, which is not convenient for the rapid treatment of waste liquid.

[0003] According to a waste liquid impurity solidification treatment device disclosed in a patent document with the existing publication number CN219031864U, which includes a waste liquid tank, and also includes a medicine adding cover body and a stirring mechanism. The medicine adding cover body covers the opening of the waste liquid tank. The medicine adding cover body is provided with a liquid inlet and a liquid return port, and both the liquid inlet and the liquid return port of the medicine adding cover body are communicated with the inner cavity of the waste liquid tank. The medicine adding cover body is also provided with a feeding hopper for adding additives that can solidify liquid impurities. A solidified matter slag discharge port is provided on the side wall of the waste liquid tank and at the bottom. When this technical solution is used, the waste liquid treatment time is shortened, the waste liquid treatment efficiency is improved, and at the same time, the clear water purified from the waste liquid can be recycled. It is not only energy-saving and environmentally friendly, but also greatly reduces the waste liquid treatment cost of enterprises. For the above technical solution, although this solution shortens the waste liquid treatment time, the flocculant cannot be evenly sprayed in all directions into the sewage during the initial feeding, which is not convenient for the rapid mixing of the flocculant and the sewage later, and there are inconveniences in use. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a ship waste liquid recycling and purification device and method to solve the problems raised in the above background technology. The structure of the present invention is novel. When in use, the sewage is sprayed obliquely from one end of the water inlet pipe and sprayed onto the rotating plate. The rotating plate drives the rotating column to rotate. The rotating column rotates and drives the material to be sprayed into the sewage from different directions through the dialing plate from the opening holes. In addition, when the rotating column rotates, the auger rotates to drive the material inside the material barrel to move downward, which is convenient for later feeding use, effectively avoiding the phenomenon that the flocculant accumulates inside the material barrel and causes difficulty in dropping.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: A ship waste liquid recycling and purification device includes a fixed box. A conical box is fixedly installed at the bottom of the fixed box. A driving motor is fixedly installed on the side of the conical box. A support box is fixed on the top of the fixed box.

[0006] Further, a rotating column is rotatably installed on the bearing seat. One end of the rotating column is welded with a rotating plate, and the rotating plate is matched with one end of the water inlet pipe. A drain pipe is fixedly installed at the bottom of the conical box.

[0007] Further, a auger is fixed at the top of the rotating column. The auger is rotatably installed inside the material bucket. A stirring plate is welded on the rotating column.

[0008] Further, a support seat is fixedly installed between the fixed box and the support box. A pushing mechanism is fixedly installed inside the support seat. A movable disk is installed on the pushing mechanism, and the movable disk is movably installed inside the barrel.

[0009] Further, a through hole is formed on the side of the barrel. A stirring assembly is rotatably installed inside the barrel, and the stirring assembly is fixedly installed on a rotating motor.

[0010] Further, a buffer seat is installed inside the fixed box. The buffer seat is fixedly installed on the support seat. A filter box is installed inside the fixed box. A movable box is movably installed on the side of the filter box. A scraping plate is movably installed on the side of the movable box, and the scraping plate is fixed on the inner wall of the fixed box. A filtering component is fixedly installed on the side of the filter box.

[0011] Further, a connecting hole is formed on the movable box. An installation hole is formed inside the filter box. A water extraction pipe is movably installed inside the installation hole, and water extraction holes are formed on the side of the water extraction pipe.

[0012] Further, one end of the water extraction pipe is fixed with a support pipe. The support pipe is fixedly installed at one end of the drain pipe, and a water pump is fixedly installed on the drain pipe.

[0013] Further, a propeller is installed on the drive motor. The propeller is rotatably installed inside the conical box. A lifting mechanism is fixedly installed on the fixed box, and one end of the lifting mechanism is fixed on the movable box.

[0014] A waste liquid recovery and purification method implemented by using the device according to claim 1, comprising the following steps: Step 1, flocculation treatment: Mix sewage and a flocculant by stirring to accelerate the rapid precipitation and flocculation of impurities in the sewage. Step 2, filtration treatment: When the sewage after flocculation moves to the side and is matched with the filtration device, rapid separation of the sewage and solids is achieved. Step 3, solid-liquid separation: Solids are adsorbed on the filtration device, and later, the soil adhering to the filtration device is pushed outwards by a scraping device.

[0015] Beneficial effects of the present invention: The ship waste liquid recovery and purification device, when in use, the sewage is sprayed out obliquely from one end of the water inlet pipe onto the rotating plate, the rotating plate drives the rotating column to rotate, the rotating column rotates to drive the material through the opening from different directions to spray into the sewage through the toggle plate, and in addition, when the rotating column rotates, the auger rotates to drive the material inside the barrel to move downward for easy feeding and use later, effectively avoiding the phenomenon that the flocculant accumulates inside the barrel and causes the material to be difficult to descend.

[0016] The device is a ship waste liquid recovery and purification device. A pushing mechanism pushes a movable plate to move upward. After the movable plate moves upward, the through hole is blocked. After sewage and flocculant are stirred and mixed at the top of the movable plate, the movable plate descends. The through hole of the movable plate is opened when it descends, so that the sewage after stirring and mixing is discharged downward. While the movable plate blocks the through hole, the upward and downward movement of the movable plate facilitates the scraping and cleaning of the inner wall of the barrel.

[0017] The device is used for recovering and purifying waste liquid from a ship. After sewage falls on a buffer seat, it moves toward a filter box. The sewage enters the position of a filter assembly on the filter box. The suction force generated by the filter assembly draws water from a suction pipe into a drain pipe. The movable box is then lowered to cooperate with the buffer seat to adjust the size of the drain opening and the drainage speed. In addition, the movement of the movable box scrapes the outer wall of the filter assembly, and the scraping pushes the mud adhered to the surface of the filter assembly downward to the inside of the conical box. The movable box then moves upward, and a scraper scrapes and cleans the outer wall of the movable box. BRIEF DESCRIPTION OF THE DRAWINGS

The pushing mechanism 34 is a linear reciprocating electric push rod. The pushing mechanism 34 pushes the movable disk 27 to move up and down inside the barrel body 5 to control the use status of the through hole 26. At the same time, the movement of the movable disk 27 completes the cleaning of the scratches on the inner wall of the barrel body 5.

[0022] In this embodiment, a through hole 26 is opened on the side of the barrel body 5, and a stirring component 28 is rotatably installed inside the barrel body 5, and the stirring component 28 is fixedly installed on the rotating motor 8. A buffer seat 25 is installed inside the fixed box 1, and the buffer seat 25 is fixedly installed on the support seat 24. A filter box 21 is installed inside the fixed box 1, and a movable box 23 is movably installed on the side of the filter box 21.

[0024] A method for recycling and purifying waste liquid using the device of claim 1, comprising the following steps: Step 1: flocculation treatment, mixing the sewage with a flocculant to accelerate the precipitation and flocculation of impurities in the sewage; Step 2: Filtration treatment: after the flocculation, the sewage moves to the side and cooperates with the filtering equipment to achieve rapid separation of sewage and solids; Step 3: Solid-liquid separation. The solid is adsorbed on the filter device. Later, the soil adhering to the filter device is pushed out through the scraping device. When the device is in use, the external pipe is connected to the water inlet pipe 6, the water inlet pipe 6 enters the sewage, and the sewage hits the rotating plate 15 in an inclined direction. The rotating plate 15 drives the rotating column 14 to rotate. When the rotating column 14 rotates, the auger 19 rotates synchronously. The rotation of the auger 19 pushes the material inside the barrel 7 to be squeezed downward. The downward squeezing of the material is convenient for later feeding. Under the push of the auger 19, the material descends and contacts the toggle plate 16. The toggle plate 16 pushes the material to be ejected from the inside of the opening 13, and is sprayed to the side through the opening 13 to the inside of the barrel body 5. The other part of the material is discharged from the bottom of the conical cylinder 12 , after falling to the rotating plate 15, the impact of the sewage causes the material to mix with the sewage. Before the sewage enters the barrel 5, the pushing mechanism 34 is started, and the pushing mechanism 34 pushes the movable plate 27 to move upward. After the movable plate 27 moves upward, the through holes 26 are distributed at the bottom of the movable plate 27, thereby blocking the sewage at the bottom of the movable plate 27, and the rotating motor 8 is started to drive the stirring component 28 to rotate. The stirring component 28 drives the sewage and the flocculant to be fully mixed. After mixing, it is still for a period of time, and then the movable plate 27 is moved downward. After the movable plate 27 moves downward, the sewage and solid matter are discharged outward from the through holes 26, and the sewage falls. The sewage falls on both sides of the support seat 24, and the sewage cooperates with the buffer seat 25 to flow to the filter box 21. The water pump 11 is started to generate suction, and the suction is transmitted to the suction pipe 30. Suction is generated through the suction hole 31 on the suction pipe 30. The suction adheres water and solids to the filter component 32 for filtration. The water enters the suction pipe 30 through the suction hole 31. The filtered and purified water is concentrated into the support pipe 35 and finally discharged through the drain pipe 10. Before the sewage enters the filter box 21, the lifting mechanism 9 is started to push the movable box 23 to move downward, and the bottom of the movable box 23 cooperates with the buffer seat 25 to adjust the sewage downward. The discharge speed, in addition, the movable box 23 moves downward to scrape and clean the surface of the filter box 21, and the sewage is continuously discharged during the scraping and cleaning. After the sewage contacts the movable box 23, the suction force passes through the connecting hole 33 to draw the sewage into the filter assembly 32 for filtration, thereby avoiding affecting the filtration during cleaning. Later, the movable box 23 moves upward, and the scraper 22 contacts the side of the movable box 23 for scraping and cleaning. The solid matter scraped and cleaned falls into the inside of the conical box 2. Later, the propeller 20 is driven by the driving motor 3 to push the solid matter inside out for centralized collection.
