Description

Technical Field

[0001] The present application relates to the field of chemical waste liquid recovery, and in particular, to a chemical waste liquid recovery device. Background Art

[0002] Pure water, after use, changes its physical or chemical properties, becoming wastewater containing various impurities. Chemical wastewater is the wastewater discharged from chemical production, including process wastewater, cooling water, exhaust gas scrubbers, and equipment and site wash water. If discharged without treatment, these wastewaters can cause varying degrees of contamination, endangering human health and impacting industrial and agricultural production.

[0003] The patent document with the announcement number CN118125526A discloses an online recovery device for chemical waste liquid, including a treatment box, a top cover is fixedly installed on the top of the treatment box by bolts, a connection port is fixedly connected to the top of the top cover, and an annular groove is opened on the outer wall of the connection port. A water evaporation mechanism is provided inside the treatment box, which relates to the technical field of chemical waste liquid. By setting the water evaporation mechanism, the toggle plate and the counterweight ball are swung back and forth, so that the heated chemical waste liquid is swung and stirred during the swinging, and the stirring is enhanced by heating the chemical waste liquid and the liquid medicine. While achieving the desired effect, it also accelerates the evaporation rate of water in the waste liquid, and the water is discharged outward through the exhaust hose at the connection port and the top of the connection port, thereby realizing automatic stirring of the chemical waste liquid during transportation. At the same time, it also accelerates the evaporation rate of the water through heating and stirring, making the chemical waste liquid viscous and the volume smaller, thereby making it easier for subsequent transportation and movement. Although the above application documents accelerate the evaporation rate of the water through heating and stirring, making the chemical waste liquid viscous and the volume smaller, thereby making it easier for subsequent transportation and movement, if the truck is on the highway, there will be no obvious braking and acceleration, so that the amplitude of the toggle plate will become smaller.

[0024] Embodiment 1, refer to Figures 1-3 , this embodiment provides a chemical waste liquid recovery device, including a treatment tank 1, and a heating rod is assembled on the outer wall of the treatment tank 1; The top of the processing tank 1 is equipped with a sleeve 21, the top of the sleeve 21 is hinged with a cylinder cover 22, the top of the processing tank 1 is equipped with a first hydraulic component, the top of the processing tank 1 is fixedly connected with a limit cover 23, the inside of the limit cover 23 is fixedly connected with a support plate 216, the top of the support plate 216 is placed with an airbag 214, the bottom of the airbag 214 is fixedly connected with a connecting hose 215, and the bottom of the connecting hose 215 is fixedly connected to the top of the processing tank 1. The front inner wall of the processing tank 1 is rotatably connected with a rotating rod 24 through a bearing, the outer wall of the rotating rod 24 is fixedly connected with a sliding rod 25, the inside of the processing tank 1 is equipped with an auxiliary device 3 for increasing the swing amplitude of the sliding rod 25, and the inside of the processing tank 1 is equipped with a cleaning device 4 for cleaning the side of the sliding rod 25. After the waste liquid enters the processing tank 1, the heating rod heats the waste liquid to make it reach the appropriate processing temperature. The first hydraulic component drives the relevant components to work, so that the sliding rod 25 makes a swinging motion in the processing tank 1 to stir and mix the waste liquid, promoting the full contact and reaction of different components in the waste liquid. The auxiliary device 3 increases the swing amplitude of the sliding rod 25 and enhances the stirring effect. The cleaning device 4 cleans the side of the sliding rod 25 during the swinging process of the sliding rod 25 to prevent waste liquid residues and the like from adhering to the sliding rod 25 and affecting its normal operation. Through the coordinated work of components such as the sleeve 21, the cylinder cover 22, the first hydraulic component, the limit cover 23, the support plate 216, the airbag 214, the rotating rod 24, and the sliding rod 25, the effective recovery and treatment of chemical waste liquid are realized, and the recovery efficiency and quality are improved. The first hydraulic component includes a first hydraulic chamber 29, the first hydraulic chamber 29 is fixedly connected to the top of the processing tank 1, one end of the piston inside the first hydraulic chamber 29 is slidably connected with a first hydraulic rod 210, one end of the piston inside the first hydraulic chamber 29 is slidably connected with a second hydraulic rod 211, the first hydraulic rod 210 is slidably connected to the left inner wall of the limit cover 23, and the hydraulic oil pushes the first hydraulic rod 210 and the second hydraulic rod 211 to make piston movements inside the first hydraulic chamber 29. The first hydraulic rod 210 is slidably connected to the left inner wall of the limit cover 23, and its expansion and contraction drive the relevant components to make the sliding rod 25 swing. The second hydraulic rod 211 cooperatively controls the movement state of the sliding rod 25, provides stable and reliable power for the swing of the sliding rod 25, ensures that it moves according to the predetermined amplitude and frequency, and realizes the full stirring and treatment of the waste liquid. The top of the processing tank 1 is fixedly connected with a second hydraulic chamber 26, one end of the piston inside the second hydraulic chamber 26 is slidably connected with a third hydraulic rod 27, one end of the piston inside the second hydraulic chamber 26 is slidably connected with a fourth hydraulic rod 28, one end of the piston inside the second hydraulic chamber 26 is slidably connected with a fifth hydraulic rod 212, a blocking plate 213 is fixedly connected to the side of the fifth hydraulic rod 212, and the hydraulic oil pushes the third hydraulic rod 27, the fourth hydraulic rod 28, and the fifth hydraulic rod 212 to make piston movements inside the second hydraulic chamber 26. A blocking plate 213 is fixedly connected to the side of the fifth hydraulic rod 212, and its expansion and contraction control the position of the blocking plate 213 to realize the opening or closing of the channel or opening inside the processing tank 1.A chute for limiting the slide bar 25 is provided at the bottom of the inner wall of the processing box 1. The bottom of the slide bar 25 is slidably connected to the bottom of the inner wall of the chute. A chute is provided at the bottom of the inner wall of the processing box 1, and the bottom of the slide bar 25 is slidably connected to the bottom of the inner wall of the chute. The chute limits the movement range of the slide bar 25, enabling it to swing stably under the drive of the hydraulic component along a predetermined trajectory, playing a role in limiting and guiding the movement of the slide bar 25, ensuring its stable movement, avoiding deviation or shaking, and improving the operation stability and reliability of the device.

[0025] When the above device is in specific use, the processing box 1 is placed inside the freight car compartment. The slide bar 25 sways by the braking and accelerating of the freight car. The heating rod is started to heat the inside of the processing box 1. By the reciprocating swaying of the slide bar 25, the swaying and stirring of the heated chemical waste liquid are realized. While heating the chemical waste liquid and the liquid medicine, the stirring effect is improved, and at the same time, the evaporation speed of the water in the waste liquid is accelerated. The gas is discharged outwards through the sleeve 21 and the airbag 214. When the freight car is driving relatively smoothly, the swaying amplitude of the slide bar 25 becomes smaller. The air inside the processing box 1 after heating rises from the connecting hose 215 to the inside of the airbag 214. The hot air causes the airbag 214 to expand and rise. When the airbag 214 rises and squeezes the first hydraulic rod 210, during the rising process of the first hydraulic rod 210, the pressure inside the first hydraulic chamber 29 increases, driving the second hydraulic rod 211 to push the slide bar 25 to swing, increasing the swinging amplitude of the slide bar 25. At the same time, when the first hydraulic rod 210 rises, it drives the fourth hydraulic rod 28 to rise. During the rising process of the fourth hydraulic rod 28, the pressure inside the second hydraulic chamber 26 increases, driving the third hydraulic rod 27 to descend. The third hydraulic rod 27 drives the cylinder cover 22 to rotate counterclockwise around the hinge point, and at the same time drives the fifth hydraulic rod 212 to move towards the back. The fifth hydraulic rod 212 drives the plug plate 213 to move towards the back to block the bottom of the connecting hose 215. When the plug plate 213 blocks the hot air, the airbag 214 descends, and the first hydraulic rod 210 resets, causing the second hydraulic rod 211, the third hydraulic rod 27, the fourth hydraulic rod 28, and the fifth hydraulic rod 212 to reset. The plug plate 213 no longer blocks the air inside the processing box 1, so that the swinging amplitude of the slide bar 25 can be continuously increased by the hot air.

[0026] Example two, see Figures 4-6, on the basis of the first embodiment, the auxiliary device 3 includes a corrugated plate 31. The corrugated plate 31 is hinged to the inner side surface of the treatment tank 1. A second hydraulic component is fixedly connected to the inner side surface of the treatment tank 1. The corrugated plate 31 is hinged to the inner side surface of the treatment tank 1, and the second hydraulic component drives the corrugated plate 31 to swing. The telescopic movement of the hydraulic rod pushes the corrugated plate 31 to swing. The corrugated plate 31 exerts a force on the sliding rod 25, driving the sliding rod 25 to swing together, increasing its swing amplitude, enhancing the swing amplitude of the sliding rod 25, making it stir the waste liquid more powerfully, and improving the treatment uniformity and efficiency. The second hydraulic component includes a third hydraulic chamber 32. The third hydraulic chamber 32 is fixedly connected to the left side of the inner wall of the treatment tank 1. One end of the piston inside the third hydraulic chamber 32 is slidably connected to a sixth hydraulic rod 33, and one end of the piston inside the third hydraulic chamber 32 is slidably connected to a seventh hydraulic rod 34. The hydraulic oil pushes the sixth hydraulic rod 33 and the seventh hydraulic rod 34 to perform piston movement inside the third hydraulic chamber 32. The telescopic movement of the sixth hydraulic rod 33 and the seventh hydraulic rod 34 acts on components such as the corrugated plate 31, controlling its swing angle and frequency, affecting the swing amplitude and manner of the sliding rod 25, providing power support for the auxiliary device 3, and precisely controlling components such as the corrugated plate 31 through the flow of hydraulic oil and the movement of the hydraulic rod, making it move in coordination with the sliding rod 25 to complete the stirring treatment of the waste liquid.

[0027] When the above device is specifically used, by braking or accelerating the truck, the liquid inside the treatment tank 1 impacts the corrugated plate 31, causing the corrugated plate 31 to rotate counterclockwise around the hinge point. The corrugated plate 31 squeezes the sixth hydraulic rod 33. When the sixth hydraulic rod 33 moves to the left, the internal pressure of the third hydraulic chamber 32 increases, driving the seventh hydraulic rod 34 to move to the right. The seventh hydraulic rod 34 exerts a pressure on the left side of the sliding rod 25, further increasing the swing amplitude of the sliding rod 25.

[0028] Example three, see Figures 4-7, on the basis of the first embodiment, the cleaning device 4 includes a scraping block 41. The scraping block 41 is fixedly connected to the bottom of the sliding rod 25. A third hydraulic component is fixedly connected to the top of the scraping block 41. A cleaning block 45 is fixedly connected to the left side of the bottom of the third hydraulic component. The scraping block 41 is fixed to the bottom of the sliding rod 25. When the sliding rod 25 swings, the scraping block 41 initially scrapes and cleans. The flow of hydraulic oil in the third hydraulic component and the movement of the hydraulic rod drive the cleaning block 45 to act. The cleaning block 45 deeply and meticulously cleans the side surface of the sliding rod 25 under the drive of the eighth hydraulic rod 44, automatically and effectively cleans the side surface of the sliding rod 25, removes impurities such as waste liquid residues, ensures the cleanliness and smooth movement of the sliding rod 25, and improves the processing effect and service life of the device. The third hydraulic component includes a fourth hydraulic chamber 42. Four first hydraulic pipes 43 are fixedly connected to the top of the four fourth hydraulic chambers 42. One end of the first hydraulic pipe 43 far from the fourth hydraulic chamber 42 is fixedly connected to the bottom of the third hydraulic chamber 32. A second hydraulic pipe 46 is fixedly connected to the top of the fourth hydraulic chamber 42. A piston in one end of the fourth hydraulic chamber 42 is slidably connected to the eighth hydraulic rod 44. The cleaning block 45 is fixedly connected to the side surface of the eighth hydraulic rod 44. The hydraulic oil is connected to the third hydraulic chamber 32 through the first hydraulic pipe 43 in the fourth hydraulic chamber 42 to achieve the circulation of hydraulic oil and the transmission of pressure. When cleaning is required, the hydraulic oil pushes the eighth hydraulic rod 44 to perform a piston movement. The expansion and contraction of the eighth hydraulic rod 44 drive the cleaning block 45 to approach or move away from the sliding rod 25 to complete the cleaning operation. The second hydraulic pipe 46 is used for oil return or balancing the hydraulic pressure, providing a stable and reliable power source for the cleaning block 45, ensuring that it cleans the sliding rod 25 according to a predetermined trajectory and force, and improving the cleaning efficiency and quality.

[0029] When the above-mentioned device is in specific use, when the sliding rod 25 swings, it drives the scraping block 41 to clean the chute at the bottom of the inner wall of the processing box 1. When the sixth hydraulic rod 33 is squeezed, the pressure inside the third hydraulic chamber 32, the first hydraulic pipe 43, and the second hydraulic pipe 46 increases, driving the eighth hydraulic rod 44 to move forward to clean the surface of the scraping block 41.

[0030] As described above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
