Description
Technical Field
[0001] This solution belongs to the field of waste acid treatment technology, specifically involving a chemical waste acid degassing treatment device. Background Technology
[0002] Waste acid degassing is a key step in waste acid treatment systems. It aims to remove volatile gaseous components from waste acid through physical or chemical methods, thereby reducing the difficulty of subsequent treatment and recovering useful resources.
[0003] Utility model patent CN205990259U discloses a degassing device for acidic waste liquid, specifically relating to a degassing device for extracting waste gas generated during the transportation of acidic waste liquid in an acid production system. This utility model includes a collection tank, an inlet pipe, a gas collection hood, a drain pipe, and a degassing fan. The inlet pipe extends into the collection tank, with its outlet below the surface of the acidic waste liquid. The gas collection hood is located within the collection tank, with an inlet at its bottom and its upper part protruding above the surface of the acidic waste liquid. The drain pipe is connected to the gas collection hood. The degassing fan is connected to both the inlet pipe and the gas collection hood via pipelines. This utility model uses the degassing fan to extract the acidic gas generated in the inlet pipe and the gas collection hood, ensuring that the acidic gas generated during the transportation of the acidic waste liquid does not overflow and cause environmental pollution or equipment corrosion.
[0004] However, the device has certain shortcomings in use. The waste gas in the waste acid inside the device can only be separated from the waste acid by vacuum decompression, and the waste gas is not easy to be discharged and treated. Utility Model Content
[0005] The purpose of this solution is to provide a chemical waste acid degassing treatment device to solve the problem that the waste gas in the waste acid in the device cannot be completely separated from the waste acid by vacuum decompression, and the waste gas is inconvenient to discharge and treat.
[0006] To achieve the above objectives, this solution provides a chemical waste acid degassing treatment device, including a degassing tank. An absorption cylinder is fixedly connected to the upper end of the degassing tank. A support plate is fixedly connected inside the absorption cylinder. A motor is fixedly installed at the upper end of the support plate. The motor's shaft passes through the support plate and is rotatably connected to it. A square rod is fixedly connected to the lower end of the motor's shaft. A gas collecting cylinder is slidably connected to the outer side of the square rod. The gas collecting cylinder and the degassing tank are movably connected. A stirring mechanism is provided on the absorption cylinder. An anti-backflow mechanism is provided on the gas collecting cylinder. A stirring rod is fixedly connected to the outer side of the gas collecting cylinder. A vacuum pump with its end penetrating the absorption cylinder is fixedly installed at the upper end of the absorption cylinder. An inlet pipe is fixedly connected inside the degassing tank.
[0007] The principle of this solution is as follows: During use, waste acid is introduced into the degassing tank through the inlet pipe. The vacuum pump is started, creating negative pressure inside the absorption cylinder, which in turn creates negative pressure inside the gas collecting cylinder. This causes the sealing plate and collection cover to detach, compressing the compression spring and creating negative pressure inside the degassing tank. The motor is then started, driving a square rod to rotate. The square rod rotates the gas collecting cylinder, which in turn rotates the stirring rod, causing it to agitate the waste acid and expel the acidic gas. This acidic gas then passes through the gas collecting cylinder and the perforated tube into the alkaline solution inside the absorption cylinder. The gas collecting cylinder rotates the perforated tube, activating the cylinder. The cylinder drives a sliding pin to move, which in turn moves the turntable. The rotating disc moves the spring, which in turn moves the support ring, which in turn moves the gas collecting cylinder, causing the stirring rod and the perforated tube to move up and down. The motor drives the square rod to rotate the gas collecting cylinder, and the cylinder drives the rotating disc, which in turn moves the support ring via the spring. This causes the gas collecting cylinder to move up and down and rotate the stirring rod and the perforated tube, stirring the waste acid and the alkaline solution in the absorption cylinder. This makes the gas in the waste acid more completely discharged and absorbed. After the vacuum pump stops working, the compression spring acts on the sealing plate, which makes it easy for the sealing plate to reset. This seals the lower end of the collection cover, preventing the alkaline solution from flowing back into the degassing tank and neutralizing the waste acid when the vacuum pump stops working.
[0008] The technical advantages of this solution are as follows: the motor drives the square rod to rotate the gas collecting cylinder, and the cylinder drives the turntable to move the support ring through the spring. This causes the gas collecting cylinder to move up and down and rotate the stirring rod and the hollow tube to stir the waste acid and the alkaline solution in the absorption cylinder, making the gas in the waste acid discharged and absorbed more completely.
[0009] The screw-like movement of the collection cover and gas collecting cylinder, combined with the action of the compression spring on the sealing plate, facilitates the repositioning of the sealing plate and seals the lower end of the collection cover. This prevents the alkaline solution from flowing back into the degassing tank and neutralizing the waste acid when the vacuum pump stops working.
[0010] Furthermore, the stirring mechanism includes a perforated tube. The perforated tube is fixedly connected inside the gas collecting cylinder, and a support ring is fixedly connected to the outside of the gas collecting cylinder. A turntable is slidably connected to the outside of the gas collecting cylinder. A cylinder is fixedly installed at the upper end of the support plate. The cylinder rod passes through the support plate and is slidably connected to it. A spring is provided on the outside of the gas collecting cylinder. A motor drives the square rod to rotate the gas collecting cylinder, and the cylinder drives the turntable, which in turn moves the support ring via the spring. This causes the gas collecting cylinder to move up and down and rotate the stirring rod and the perforated tube, stirring the waste acid and the alkaline solution in the absorption cylinder, resulting in more complete gas discharge and absorption treatment of the waste acid.
[0011] Furthermore, a sliding pin is fixedly connected to the surface of the cylinder rod, and the sliding pin is slidably connected to the turntable. The movement of the turntable is controlled by the sliding pin.
[0012] Furthermore, a hanger rod is fixedly connected to the upper end of the support ring, and the hanger rod is slidably connected to the turntable. The hanger rod restricts the position of the support rings.
[0013] Furthermore, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the turntable. By setting the spring, the support ring is elastically compressed downwards.
[0014] Furthermore, the backflow prevention mechanism includes a collection cover. The collection cover is threadedly connected to the outer side of the gas collecting cylinder. A support plate is fixedly connected inside the gas collecting cylinder. A guide rod is fixedly connected to the lower end of the support plate. A sealing plate is slidably connected to the outer side of the guide rod. The sealing plate and the collection cover are fixedly connected. A compression spring is provided on the outer side of the guide rod. Through the threaded movement of the collection cover and the gas collecting cylinder, and the action of the compression spring on the sealing plate, the sealing plate can be easily reset, thus sealing the lower end of the collection cover. This prevents the alkaline solution from flowing back into the degassing tank and neutralizing the waste acid when the vacuum pump stops working.
[0015] Furthermore, one end of the compression spring is fixedly connected to the support plate, and the other end of the compression spring is fixedly connected to the sealing plate. By setting the compression spring, the sealing plate can be easily reset. Attached Figure Description

[0022] The implementation examples are basically as follows Figure 1 , Figure 2 As shown, this embodiment provides a chemical waste acid degassing treatment device, including a degassing tank 1. An absorption cylinder 2 is fixedly connected to the upper end of the degassing tank 1. A support plate 3 is fixedly connected inside the absorption cylinder 2. A motor 4 is fixedly installed at the upper end of the support plate 3. The rotating shaft of the motor 4 passes through the support plate 3 and is rotatably connected to the support plate 3. A square rod 5 is fixedly connected to the lower end of the rotating shaft of the motor 4. A gas collecting cylinder 6 is slidably connected to the outside of the square rod 5. The gas collecting cylinder 6 is movably connected to the degassing tank 1. A stirring mechanism 7 is provided on the absorption cylinder 2. An anti-backflow mechanism 8 is provided on the gas collecting cylinder 6. A stirring rod 9 is fixedly connected to the outside of the gas collecting cylinder 6. A vacuum pump 10 with its end penetrating the absorption cylinder 2 is fixedly installed at the upper end of the absorption cylinder 2. An inlet pipe 11 is fixedly connected inside the degassing tank 1.
[0023] like Figure 2 , Figure 3 As shown, the stirring mechanism 7 includes a perforated tube 71. The perforated tube 71 is fixedly connected inside the air collecting cylinder 6. A support ring 72 is fixedly connected to the outside of the air collecting cylinder 6. A turntable 73 is slidably connected to the outside of the air collecting cylinder 6. A cylinder 74 is fixedly installed at the upper end of the support plate 3. The cylinder rod of the cylinder 74 passes through the support plate 3 and is slidably connected to it. A sliding pin 75 is fixedly connected to the surface of the cylinder rod of the cylinder 74. The sliding pin 75 is slidably connected to the turntable 73. By setting the sliding pin 75, the movement of the turntable 73 is controlled. A hanging rod 76 is fixedly connected to the upper end of the support ring 72. The hanging rod 76 is slidably connected to the turntable 73. To restrict the position of the support rings 72, a spring 77 is provided on the outside of the gas collecting cylinder 6. One end of the spring 77 is fixedly connected to the support ring 72, and the other end of the spring 77 is fixedly connected to the turntable 73. By setting the spring 77, the support ring 72 is elastically squeezed downward. The motor 4 drives the square rod 5 to rotate the gas collecting cylinder 6, and the cylinder 74 drives the turntable 73 to move the support ring 72 through the spring 77. This causes the gas collecting cylinder 6 to move up and down and rotate the stirring rod 9 and the hollow tube 71 to stir the waste acid and the alkaline solution in the absorption cylinder 2, so that the gas in the waste acid is discharged and absorbed more completely.
[0024] like Figure 2 , Figure 4As shown, the backflow prevention mechanism 8 includes a collection cover 81. The outer side of the gas collecting cylinder 6 is connected to the collection cover 81 by threads. The inner side of the gas collecting cylinder 6 is fixedly connected to a support plate 82. The lower end of the support plate 82 is fixedly connected to a guide rod 83. The outer side of the guide rod 83 is slidably connected to a sealing plate 84. The sealing plate 84 and the collection cover 81 are fixedly connected. A compression spring 85 is provided on the outer side of the guide rod 83. One end of the compression spring 85 is fixedly connected to the support plate 82, and the other end of the compression spring 85 is fixedly connected to the sealing plate 84. By providing the compression spring 85, the sealing plate 84 can be easily reset. The collection cover 81 and the gas collecting cylinder 6 make threaded movements, and the compression spring 85 acts on the sealing plate 84, thereby making the sealing plate 84 easy to reset. This closes the lower end of the collection cover 81, preventing the alkaline solution from flowing back into the degassing tank 1 and causing the waste acid to be neutralized when the vacuum pump 10 stops working.
[0025] The specific implementation process of this utility model is as follows: In use, waste acid is introduced into the degassing tank 1 through the inlet pipe 11. The vacuum pump 10 is started, and the vacuum pump 10 draws in air, creating a negative pressure inside the absorption cylinder 2, which in turn creates a negative pressure inside the gas collecting cylinder 6. This causes the sealing plate 84 and the collection cover 81 to separate, compressing the compression spring 85, which in turn creates a negative pressure inside the degassing tank 1. The motor 4 is started, driving the square rod 5 to rotate. The square rod 5 drives the gas collecting cylinder 6 to rotate, which in turn drives the stirring rod 9 to rotate, causing the stirring rod 9 to stir the waste acid. This causes the acidic gas in the waste acid to be discharged, allowing the acidic gas to enter the alkaline solution inside the absorption cylinder 2 through the gas collecting cylinder 6 and the perforated tube 71. The gas collecting cylinder 6 drives the perforated tube 71 to rotate, and the cylinder 74 is started, driving the sliding pin 75 to move. The sliding pin 75 drives the turntable 7... 3. The turntable 73 moves, driving the spring 77 to move, which in turn moves the support ring 72, which in turn moves the gas collecting cylinder 6, causing the stirring rod 9 and the hollow tube 71 to move up and down. The motor 4 drives the square rod 5 to rotate the gas collecting cylinder 6, and the cylinder 74 drives the turntable 73 to move the support ring 72 via the spring 77, which in turn causes the gas collecting cylinder 6 to move up and down and rotate the stirring rod 9 and the hollow tube 71 to stir the waste acid and the alkaline solution in the absorption cylinder 2, making the gas in the waste acid more completely discharged and absorbed. After the vacuum pump 10 stops working, the compression spring 85 acts on the sealing plate 84, which makes it easy for the sealing plate 84 to reset, thus sealing the lower end of the collection cover 81, preventing the alkaline solution from flowing back into the degassing tank 1 and causing the waste acid to be neutralized when the vacuum pump 10 stops working.
[0026] The motor 4 drives the square rod 5 to rotate the gas collecting cylinder 6, and the cylinder 74 drives the turntable 73 to move the support ring 72 through the spring 77. This causes the gas collecting cylinder 6 to move up and down and rotate the stirring rod 9 and the hollow tube 71 to stir the waste acid and the alkaline solution in the absorption cylinder 2, making the gas in the waste acid discharged and absorbed more completely.
[0027] The screw motion of the collecting cover 81 and the gas collecting cylinder 6, and the action of the compression spring 85 on the sealing plate 84, makes it easy for the sealing plate 84 to reset, thereby sealing the lower end of the collecting cover 81. This prevents the alkaline solution from flowing back into the degassing tank 1 and causing the waste acid to be neutralized when the vacuum pump 10 stops working.
