Description

Technical Field

[0001] The present invention relates to the field of waste liquid treatment equipment, and particularly to a device for solidifying impurities in waste liquid. Background Art

[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 equipment disclosed in a patent document with the publication number CN219031864U, it 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 an additive 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 the treatment time is shortened, when adding the additive in the early stage, the metering of the additive entering cannot be controlled, and it cannot be quickly mixed and stirred with the waste liquid when entering, which is inconvenient in use. Summary of the Invention

Later, the movable tube slowly moves downward, and the additive is slowly discharged downward by pushing the piston plate. When discharging, the waste liquid enters the cavity through the opening hole and the liquid inlet hole. The waste liquid and the discharged additive are preliminarily mixed in the opening hole and then mixed again after entering the cavity, which is beneficial to improving the mixing efficiency.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: A device for solidifying impurities in waste liquid includes a base, a box body is fixed on the base, a driving motor and a slag discharge pipe are respectively fixedly installed at one end of the box body, a cover plate is movably installed on the top of the box body, the cover plate is fixedly installed on the box body through fixing bolts, a movable tube is movably installed on the cover plate, scale lines are opened on the movable tube, a limiting disk is fixedly installed at the top of the movable tube, a feeding port is fixedly installed on the side of the movable tube, a cavity is opened inside the box body, and a roller is rotatably installed inside the cavity.

One end of the supporting mechanism is fixed with a limiting block, and the limiting block is fixedly installed on the inner wall of the movable pipe.

[0008] Further, a sealing ring is fixed at one end of the fixed pipe. The sealing ring is in contact with the inner wall of the movable pipe. An opening is formed at the bottom of the fixed pipe. A water inlet pipe is fixed at one end of the fixed pipe. The water inlet pipe is fixedly installed on the side of the box body, and a liquid injection hole is formed between the water inlet pipe and the cavity.

When discharging, the waste liquid enters the cavity through the opening hole and the liquid inlet hole. The waste liquid and the discharged additive are preliminarily mixed inside the opening hole and then mixed again inside the cavity, which is beneficial to improving the mixing efficiency. When the movable tube controls the discharging speed of the additive, later the movable tube moves downward to block and seal the opening hole and the liquid injection hole, effectively preventing the liquid inside the cavity from flowing backward outward.

[0016] For the waste liquid impurity solidification treatment device, when the driving motor rotates forward, it drives the rotating cylinder to rotate inside the drum, rotates and adjusts the position of the bottom filter screen, replaces the position of the bottom filter screen to contact with the liquid, effectively preventing blockage caused by the upward movement of the liquid later. Additionally, when the rotating cylinder rotates in reverse, it drives the drum to rotate through the cooperation of the arc-shaped block and the convex block.

Detailed implementation mode

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation mode.

[0020] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a waste liquid impurity solidification treatment device, including a base 1, a box body 2 is fixed on the base 1, a driving motor 9 and a slag discharge pipe 10 are respectively and fixedly installed at one end of the box body 2, a cover plate 3 is movably installed on the top of the box body 2, the cover plate 3 is fixedly installed on the box body 2 through a fixing bolt 4, a movable pipe 5 is movably installed on the cover plate 3, a scale line 7 is opened on the movable pipe 5, a limiting disc 6 is fixedly installed at the top of the movable pipe 5, a feed inlet 33 is fixedly installed on the side of the movable pipe 5, a cavity 11 is opened inside the box body 2, a roller 12 is rotatably installed inside the cavity 11, the height of the upward movement of the movable pipe 5 is understood through the scale line 7, and the quantitative addition of the additive is completed by combining the height of the movement of the movable pipe 5 with the space inside the fixed pipe 17.

[0021] In this embodiment, a filtering component 22 and a stirring plate 13 are fixedly installed on the roller 12. The filtering component 22 is a filter plate, which realizes the separation of solids and water. Water enters the inside of the rotating cylinder 23 through the filtering component 22. Through holes 14 are formed in the stirring plate 13, mounting holes 16 are formed in the box body 2, a fixed pipe 17 is fixedly installed inside the mounting holes 16, the fixed pipe 17 is movably installed inside the movable pipe 5, a limiting groove 18 is formed on the side of the fixed pipe 17, a support mechanism 19 is fixedly installed inside the limiting groove 18, one end of the support mechanism 19 is fixed with a limiting block, the limiting block is fixedly installed on the inner wall of the movable pipe 5, a sealing ring 20 is fixed at one end of the fixed pipe 17, the sealing ring 20 is in contact with the inner wall of the movable pipe 5, a through hole 34 is formed at the bottom of the fixed pipe 17, a water inlet pipe 8 is fixed at one end of the fixed pipe 17, the water inlet pipe 8 is fixedly installed on the side of the box body 2, a liquid injection hole 36 is formed between the water inlet pipe 8 and the cavity 11. The support mechanism 19 is a support spring, which pushes the limiting block and the movable pipe 5 to move downward slowly. When the movable pipe 5 moves downward, the liquid inside the fixed pipe 17 is pushed out from the through hole 34 by the piston plate 35.

[0022] In this embodiment, a threaded hole 15 is formed in the box body 2, one end of the fixing bolt 4 is rotatably installed inside the threaded hole 15, a rotating cylinder 23 is rotatably installed inside the roller 12, an arc-shaped block 24 is fixed on the side of the rotating cylinder 23, a groove 29 is formed on the inner wall of the roller 12, a convex block 31 is movably installed inside the groove 29, the convex block 31 is installed inside the groove 29 through a return shaft 32, an output shaft 25 is fixed at one end of the rotating cylinder 23, the convex block 31 and the arc-shaped block 24 cooperate with each other, magnets 30 are fixed inside both the convex block 31 and the groove 29, and the magnets 30 repel each other. The output shaft 25 is fixedly installed on the driving motor 9, a filter net is fixedly installed on the rotating cylinder 23. A thrust is generated between the magnets 30, which pushes the convex block 31 to move downward. After the convex block 31 moves downward, when the arc-shaped block 24 reverses, it provides power for the rotation of the roller 12.

[0023] In this embodiment, a movable column 28 is fixed on the limiting disc 6, a piston plate 35 is fixed at one end of the movable column 28, the piston plate 35 is movably installed inside the fixed pipe 17, a collection groove 26 is formed at the bottom of the cavity 11, a screw conveyor 27 is rotatably installed inside the collection groove 26, the screw conveyor 27 is rotatably installed inside the slag discharge pipe 10, a rotating motor and a water suction pipe 21 are fixedly installed at the other end of the box body 2, the water suction pipe 21 is fixedly installed inside the rotating cylinder 23, and the screw conveyor 27 is installed on the rotating motor. The rotation of the screw conveyor 27 pushes the solids at the bottom to be discharged outwards from the inside of the slag discharge pipe 10 through the inside.

[0024] When the device is in use, the limiting disc 6 drives the movable pipe 5 to move upward. When the movable pipe 5 moves upward, it squeezes the support mechanism 19 through the limiting block. The support mechanism 19 squeezes and contracts to provide space for the upward movement of the movable pipe 5. As the movable pipe 5 moves upward, the rising height of the movable pipe 5 is observed according to the scale line 7. The combination of the scale line 7 and the fixed pipe 17 completes the measurement of the amount of internal additive added. After the movable pipe 5 moves upward, the additive is added into the fixed pipe 17 through the feed port 33. After the additive is added, the limiting disc 6 is released. The movable pipe 5 moves downward under the push of the support mechanism 19. When moving downward, the piston plate 35 pushes the additive to be discharged into the inside of the water inlet pipe 8 through the opening 34. The water inlet pipe 8 admits waste liquid. The waste liquid and the additive enter the inside of the cavity 11 through the liquid injection hole 36. As the waste liquid and the additive enter, the piston plate 35 moves slowly downward. When the movable pipe 5 blocks the opening 33, the waste liquid cannot enter the inside of the cavity 11 again, and the liquid inside the cavity 11 cannot flow back either. After entering the inside of the cavity 11, the driving motor 9 is started to reverse. The driving motor 9 drives the rotating cylinder 23 to reverse. The reverse rotation of the rotating cylinder 23 causes the arc-shaped block 24 to cooperate with the convex block 31 to drive the roller 12 to rotate. The rotation of the roller 12 stirs the waste liquid through the stirring plate 13. After the waste liquid is stirred, the solid-liquid separation effect is accelerated. When the solid in the water is formed, it falls downward to the bottom of the cavity 11. The driving motor 9 is turned off to provide a static space for the reaction of the liquid. During solid-liquid separation, the water moves upward. The water moves upward through the bottom filter assembly 22. The double filtration is realized by the cooperation of the filter assembly 22 and the filter screen on the rotating cylinder 23; In the later stage, the driving motor 9 is started to drive the rotating cylinder 23 to rotate forward. The forward rotation of the rotating cylinder 23 changes the position of the bottom filter screen to prevent the bottom filter screen from being blocked and affecting the later water inlet. When the water enters the inside of the rotating cylinder 23, it is pumped out through the water extraction pipe 21 for reuse. After the water is pumped out, the rotating motor is started to drive the auger 27 to rotate. The auger 27 rotates inside the collection tank 26 and the slag discharge pipe 10 to push the solid outwards. While the solid is being discharged, the roller 12 rotates again. The roller 12 scrapes the inner wall of the cavity 11 through the stirring plate 13 to clean the inside of the cavity 11, and the cleaning pushes the solid into the inside of the collection tank 26 for discharge.
