Description

Technical Field

[0001] This invention relates to the technical field of strong acid waste liquid hydrolysis and neutralization devices, specifically a strong acid waste liquid hydrolysis and neutralization device. Background Technology

[0002] A liquid hydrolysis neutralization device is a specialized piece of equipment used in chemical, environmental, or material preparation processes to neutralize acidic or alkaline liquids after hydrolysis. Its core purpose is to adjust the pH of the hydrolysate to a target range (such as neutral or emission standards) by adding acid or alkali, while simultaneously promoting precipitation, crystallization, or subsequent separation processes.

[0003] Existing strong acid waste liquids release a large amount of heat instantaneously during the neutralization reaction. Most devices lack efficient and stable cooling and temperature control structures, which can easily cause the temperature of the reaction system to rise abnormally, potentially leading to safety hazards such as liquid splashing and large-scale volatilization of acid mist. At the same time, high temperature conditions may also affect the stability of the neutralization reaction. Summary of the Invention

[0012] Furthermore, the end of the inlet pipe away from the circulating cooling pipe is fixedly connected to the output end of the water-cooled pump, the end of the return pipe away from the circulating cooling pipe is fixedly connected to the bottom of the cooling water tank, the outer wall of the circulating cooling pipe is fixedly connected to the inner wall of the mixing tank, and the alkali spray gun, the chemical spray gun and the strong acid waste liquid spray gun are close to the top of the mixing tank and extend into the interior of the mixing tank.

[0013] Furthermore, the mixing mechanism includes a rotating shaft, a fixed ring is fixedly connected to the surface of the rotating shaft, a stirring rod is fixedly connected to the outer wall of the fixed ring, a stirring shaft is fixedly connected to the end of the stirring rod away from the fixed ring, a rotating cylinder is rotatably connected to the surface of the stirring shaft, and a mixing rod is fixedly connected to the surface of the rotating cylinder.

[0014] Furthermore, the end of the rotating shaft is fixedly connected to the output end of the motor, the end of the rotating shaft away from the motor is rotatably connected to the top of the support plate, the end of the cleaning brush away from the cleaning plate is in contact with the surface of the circulating cooling pipe, the end of the connecting plate away from the cleaning plate is fixedly connected to the outer wall of the rotating shaft, and the number of stirring shafts is set to six, which are divided into three groups of two each, and the six rotating cylinders are symmetrically arranged with the fixing ring as the center.

[0015] Furthermore, the impact mechanism includes a lower driven plate, a force-bearing block fixedly connected to the bottom of the lower driven plate, a right-angle connecting plate fixedly connected to the end of the lower driven plate away from the force-bearing block, a slip ring fixedly connected to the end of the right-angle connecting plate away from the lower driven plate, a push rod hinged to the surface of the slip ring, a reset elastic rod fixedly connected to the bottom of the upper driven plate, impact bending rods fixedly connected to both sides of the sliding plate, and a squeezing rod fixedly connected to the bottom of the inner wall of the mixing tank.

[0017] The present invention has the following beneficial effects:

[0018] This invention uses a water-cooled pump to drive the coolant to circulate continuously in a circulating cooling pipe. The circulating cooling pipe is in close contact with the inner wall of the mixing tank and directly contacts the reaction liquid. This can remove a large amount of heat generated by the neutralization reaction in real time, accurately control the reaction temperature, avoid excessive temperature causing splashing, and significantly improve the safety of the device operation and the stability of the reaction.

[0019] This invention uses a motor-driven rotating shaft to synchronously rotate the stirring rod, stirring shaft, rotating drum, and mixing rod. The rotating drum can rotate autonomously due to liquid resistance, forming multidimensional turbulent mixing, which allows the alkaline solution, chemical solution, and strong acid waste liquid to be mixed quickly and evenly, greatly improving the hydrolysis and neutralization efficiency.

[0020] This invention uses a rotating shaft to drive a connecting plate, a cleaning plate, and a cleaning brush to rotate continuously. The cleaning brush scrapes against the surface of the circulating cooling pipe, promptly removing scale, deposits, and viscous waste liquid adhering to the pipe wall, keeping the heat exchange surface of the circulating cooling pipe clean, avoiding a decrease in cooling efficiency due to scale buildup, and maintaining high-efficiency heat dissipation capacity for a long time.

[0021] This invention uses the periodic cooperation of the force block and the extrusion rod to drive the impact bending rod to reciprocate to impact the cleaning plate, causing the cleaning brush to vibrate at high frequency, powerfully shaking off residual dirt on the brush surface and achieving self-cleaning. At the same time, the reciprocating motion of the lower driven plate and the upper driven plate can agitate the liquid a second time, further improving the mixing uniformity, and can also gather acid mist to prevent overflow.

[0022] This invention uses a fan and a negative pressure pipe to concentrate and exhaust the acid mist generated by the reaction, thus avoiding acid mist corrosion of equipment, environmental pollution, or harm to the health of operators.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-10 As shown, the present invention is a strong acid waste liquid hydrolysis neutralization device, including a mixing tank 1, a motor 2 fixedly connected to the top of the mixing tank 1, a one-way valve 3 provided at the bottom of the mixing tank 1, an exhaust fan 4 fixedly connected to the surface of the mixing tank 1, a negative pressure pipe 5 fixedly connected to the output end of the exhaust fan 4, a support plate 6 fixedly connected to the bottom of the inner wall of the mixing tank 1, and also includes;

[0039] The cooling mechanism 10 includes an inlet pipe 13, with a circulating cooling pipe 15 fixedly connected to the end of the inlet pipe 13. A return pipe 14 is fixedly connected to the end of the circulating cooling pipe 15 away from the inlet pipe 13. Since the circulating cooling pipe 15 is arranged on the inner wall of the mixing tank 1, it can directly contact the alkaline solution, reagents and strong acid waste liquid in the tank. When the coolant flows through the circulating cooling pipe 15, it can directly cool and dissipate heat during the reaction process of the mixed materials in the tank. After the heat exchange is completed, the coolant flows back to the cooling water tank 11 through the return pipe 14. The coolant is continuously circulated and transported by the water-cooled pump 12, so that the circulating cooling pipe 15 always maintains a low temperature heat exchange state, effectively controlling the heat generated by the material reaction and avoiding the reaction system temperature from being too high.

[0040] The mixing mechanism 30 includes a connecting plate 37, a cleaning plate 38 is fixedly connected to the end of the connecting plate 37, and a cleaning brush 39 is fixedly connected to the surface of the cleaning plate 38.

[0041] The impact mechanism 50 includes a slide plate 56, with a pull rod 57 hinged to the top of the slide plate 56. An upper driven plate 58 is hinged to the end of the pull rod 57 away from the slide plate 56. When the force block 52 finishes contacting the compression rod 61, the lower driven plate 51, force block 52, right-angle connecting plate 53, slip ring 54, push rod 55, slide plate 56, pull rod 57, upper driven plate 58, reset elastic rod 59, and impact bending rod 60 will simultaneously reset. Because the rotating shaft 31 continuously drives the lower driven plate 51 to rotate, the compression rod 61 can continuously and periodically compress and push the rotating force block 52, causing the lower driven plate 51 and the upper driven plate 58 to continuously reciprocate and slide towards each other, while simultaneously driving the impact bending rod 60 continuously... The impact cleaning plate 38 is broken. At the same time, the reciprocating sliding motion of the lower driven plate 51 and the upper driven plate 58 can perform secondary agitation and mixing of the internal liquid, effectively improving the mixing uniformity and efficiency of the liquid materials. Moreover, this reciprocating motion can gather the acid mist generated during the liquid reaction in the middle area of ​​the equipment, effectively preventing the acid mist from spreading and overflowing outward, and improving the sealing and safety of the equipment operation. The impact action can cause the cleaning plate 38 and the matching cleaning brush 39 to vibrate continuously, which can effectively shake off the residual liquid adhering to the surface of the cleaning brush 39, achieving a self-cleaning effect. The concentrated acid mist will be discharged to the next process through the negative pressure pipe 5. After the reaction is completed, the one-way valve 3 is opened to discharge the mixed liquid.

[0042] The bottom of the mixing tank 1 is provided with a discharge hole, and a support plate is fixedly connected to the bottom of the mixing tank 1. The surface of the mixing tank 1 is provided with observation holes and negative pressure exhaust holes. The inner wall of the negative pressure pipe 5 and the inner wall of the negative pressure exhaust hole are interconnected.

[0043] The cooling mechanism 10 includes a cooling water tank 11. A water-cooled pump 12 is fixedly connected to the top of the mixing tank 1. An alkaline spray gun 16, a chemical spray gun 17, and a strong acid waste liquid spray gun 18 are fixedly connected to the inner wall of the mixing tank 1. First, the alkaline solution, chemical solution, and strong acid waste liquid are added to the interior of the mixing tank 1 at a uniform speed through the alkaline spray gun 16, the chemical spray gun 17, and the strong acid waste liquid spray gun 18 to mix and react. During the reaction of the three liquids, a certain amount of heat is generated. The water-cooled pump 12 is started to draw coolant from the cooling water tank 11. The coolant is transported to the interior of the circulating cooling pipe 15 through the liquid inlet pipe 13.

[0044] The end of the inlet pipe 13 away from the circulating cooling pipe 15 is fixedly connected to the output end of the water-cooled pump 12. The end of the return pipe 14 away from the circulating cooling pipe 15 is fixedly connected to the bottom of the cooling water tank 11. The outer wall of the circulating cooling pipe 15 is fixedly connected to the inner wall of the mixing tank 1. The alkali spray gun 16, the chemical spray gun 17 and the strong acid waste spray gun 18 are close to the top of the mixing tank 1 and extend into the top of the mixing tank 1.

When the alkali solution, the chemical solution, and the strong acid waste liquid are added into the mixing tank 1, the motor 2 is started to drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, it will drive the fixed ring 32 to rotate. When the fixed ring 32 rotates, it will simultaneously drive the stirring rod 33 and the connecting plate 37. When the stirring rod 33 rotates, it will drive the stirring shaft 34. During the rotation of the stirring shaft 34, the liquid will be stirred and mixed. When the stirring shaft 34 rotates, it will drive the rotating drum 35 and the mixing rod 36 to rotate. During the rotation of the rotating drum 35, it will rotate on the surface of the stirring shaft 34 due to the resistance of the liquid, so that the three liquids are fully mixed.

[0046] The end of the rotating shaft 31 is fixedly connected to the output end of the motor 2. The end of the rotating shaft 31 away from the motor 2 is rotatably connected to the top of the support plate 6. The end of the cleaning brush 39 away from the cleaning plate 38 contacts the surface of the circulating cooling pipe 15. The end of the connecting plate 37 away from the cleaning plate 38 is fixedly connected to the outer wall of the rotating shaft 31. There are six stirring shafts 34, which are divided into three groups of two. The six rotating cylinders 35 are symmetrically arranged around the fixing ring 32. When the connecting plate 37 rotates, it will drive the cleaning plate 38 to rotate. When the cleaning plate 38 rotates, it will drive the cleaning brush 39 to rotate. During the rotation of the cleaning brush 39, the surface of the circulating cooling pipe 15 will be cleaned to prevent liquid from adhering to the surface of the circulating cooling pipe 15 and causing poor cooling. The stirring shaft 34, rotating cylinder 35 and mixing rod 36 will effectively mix the alkaline solution, chemical solution and strong acid waste liquid during the rotation. At the same time, the cleaning brush 39 will clean the surface of the circulating cooling pipe 15 during the rotation.

[0047] The impact mechanism 50 includes a lower driven plate 51, with a force-receiving block 52 fixedly connected to the bottom of the lower driven plate 51. A right-angle connecting plate 53 is fixedly connected to the end of the lower driven plate 51 away from the force-receiving block 52. A slip ring 54 is fixedly connected to the end of the right-angle connecting plate 53 away from the lower driven plate 51. A push rod 55 is hinged to the surface of the slip ring 54. A reset elastic rod 59 is fixedly connected to the bottom of the upper driven plate 58. Impact bending rods 60 are fixedly connected to both sides of the sliding plate 56. An extrusion rod 61 is fixedly connected to the bottom of the inner wall of the mixing tank 1. When the lower driven plate 51 slides, it pushes the right-angle connecting plate 53 to move upward. When moving, the slip ring 54 is pushed to slide upward on the surface of the rotating shaft 31. When the slip ring 54 slides, it pushes the end of the push rod 55 to move upward, while the other end of the push rod 55 pushes the slide plate 56 to slide in a direction away from each other on the surface of the connecting plate 37. When the slide plate 56 slides, it pulls the end of the pull rod 57 to move in a direction away from each other. Then the other end of the pull rod 57 pulls the driven plate 58 to slide downward on the surface of the rotating shaft 31 and pushes the reset elastic rod 59 to retract downward. When the slide plate 56 slides, it drives the impact bending rod 60 to move in a direction away from each other and impacts the surface of the cleaning plate 38.

[0048] The top of the lower driven disc 51 is fixedly connected to the end of the reset elastic rod 59. The end of the reset elastic rod 59 away from the lower driven disc 51 is fixedly connected to the surface of the stirring rod 33. When the rotating shaft 31 rotates, it will drive the lower driven disc 51, the slip ring 54, and the upper driven disc 58 to rotate simultaneously. When the upper driven disc 58 rotates, it will drive the pull rod 57 and the reset elastic rod 59 to rotate simultaneously. When the slip ring 54 rotates, it will drive the push rod 55 and the slide plate 56 to rotate. When the lower driven disc 51 rotates, it will drive the force block 52 to rotate. During the movement, it will contact the extrusion rod 61 and extrude the extrusion rod 61 to extrude the force block 52, causing the force block 52 to move upward. When the force block 52 moves, it will push the driven plate 51 to slide upward on the surface of the rotating shaft 31 and push the reset elastic rod 59 to retract upward. The inner wall of the slip ring 54 is slidably connected to the surface of the rotating shaft 31. The end of the push rod 55 away from the slip ring 54 is hinged to the bottom of the slide plate 56. The inner wall of the slide plate 56 is slidably connected to the surface of the connecting plate 37. The surface of the force block 52 is in contact with the surface of the extrusion rod 61.

[0049] In use, alkali solution, chemical solution, and strong acid waste liquid are first added to the mixing tank 1 at a uniform speed through the alkali solution spray gun 16, the chemical solution spray gun 17, and the strong acid waste liquid spray gun 18 respectively for mixing and reaction. During the reaction of the three liquids, a certain amount of heat is generated. The water-cooling pump 12 is started to draw coolant from the cooling water tank 11. The coolant is then transported to the circulating cooling pipe 15 through the inlet pipe 13. Since the circulating cooling pipe 15 is located on the inner wall of the mixing tank 1, it can directly contact the alkali solution, chemical solution, and strong acid waste liquid inside the tank. As the coolant flows through the circulating cooling pipe 15, it can directly cool and dissipate heat during the reaction process of the mixture inside the tank. After heat exchange, the coolant flows back to the cooling water tank 11 through the return pipe 14. The water-cooling pump 12 continuously circulates and transports the coolant, ensuring continuous circulation. Cooling pipe 15 maintains a low-temperature heat exchange state, effectively controlling the heat generated by the material reaction and preventing the reaction system temperature from becoming too high. After the alkali solution, chemical solution, and strong acid waste liquid are added to the mixing tank 1, motor 2 is started to drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, it drives the fixed ring 32 to rotate. When the fixed ring 32 rotates, it simultaneously drives the stirring rod 33 and the connecting plate 37. When the stirring rod 33 rotates, it drives the stirring shaft 34. During the rotation of the stirring shaft 34, the liquid is stirred and mixed. When the stirring shaft 34 rotates, it drives the rotating drum 35 and the mixing rod 36 to rotate. During the rotation of the rotating drum 35, the mixture rotates on the surface of the stirring shaft 34 due to the resistance of the liquid, thus fully mixing the three liquids. When the connecting plate 37 rotates, it drives the mixing rod 36 to rotate. The cleaning plate 38 rotates, which in turn drives the cleaning brush 39 to rotate. During the rotation of the cleaning brush 39, the surface of the circulating cooling pipe 15 is cleaned to prevent liquid from adhering to the surface and causing poor cooling. The mixing shaft 34, rotating drum 35, and mixing rod 36 effectively mix the alkaline solution, chemical solution, and strong acid waste liquid during rotation. Simultaneously, the cleaning brush 39 cleans the surface of the circulating cooling pipe 15. While the rotating shaft 31 rotates, it also drives the lower driven plate 51, slip ring 54, and upper driven plate 58 to rotate simultaneously. The rotation of the upper driven plate 58 drives the pull rod 57 and the reset elastic rod 59 to rotate simultaneously, while the rotation of the slip ring 54... When the push rod 55 and the slide plate 56 rotate, the driven plate 51 rotates, causing the force block 52 to rotate. During the rotation of the force block 52, it comes into contact with the pressing rod 61, which presses the force block 52, causing it to move upward. As the force block 52 moves, it pushes the driven plate 51 to slide upward on the surface of the rotating shaft 31 and pushes the return elastic rod 59 to retract upward. When the driven plate 51 slides, it pushes the right-angle connecting plate 53 to move upward. When the right-angle connecting plate 53 moves, it pushes the slip ring 54 to slide upward on the surface of the rotating shaft 31. When the slip ring 54 slides, it pushes the end of the push rod 55 to move upward, while the other end of the push rod 55 pushes the slide plate 56 to slide in a direction away from each other on the surface of the connecting plate 37.When the slide plate 56 slides, it pulls the end of the pull rod 57 to move away from each other. The other end of the pull rod 57 then pulls the upper driven plate 58 to slide downwards on the surface of the rotating shaft 31, pushing the reset elastic rod 59 downwards. As the slide plate 56 slides, it causes the impact bend rod 60 to move away from each other and impact the surface of the cleaning plate 38. When the force block 52 and the pressing rod 61 cease contact, the lower driven plate 51, force block 52, right-angle connecting plate 53, slip ring 54, push rod 55, slide plate 56, pull rod 57, upper driven plate 58, reset elastic rod 59, and impact bend rod 60 will simultaneously reset. Because the rotating shaft 31 continuously drives the lower driven plate 51 to rotate, the pressing rod 61 can continuously and periodically press and push the rotating force block 52, causing the lower driven plate 51 and the upper driven plate 58 to retract downwards. The disk 58 continuously slides towards each other, simultaneously causing the impact rod 60 to continuously impact the cleaning plate 38. At the same time, the reciprocating sliding motion of the lower driven disk 51 and the upper driven disk 58 further agitates and mixes the internal liquid, effectively improving the mixing uniformity and efficiency. This reciprocating motion also concentrates the acid mist generated during the liquid reaction in the central area of ​​the equipment, effectively preventing the acid mist from spreading outwards and improving the sealing and safety of the equipment. The impact causes the cleaning plate 38 and its associated cleaning brush 39 to vibrate continuously, effectively shaking off residual liquid adhering to the surface of the cleaning brush 39, achieving a self-cleaning effect. The concentrated acid mist is then discharged to the next process through the negative pressure pipe 5. After the reaction is complete, the one-way valve 3 is opened to discharge the mixed liquid.
