Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology for rubber accelerators, specifically to a wastewater treatment device for CBS (carbon barium sulfate) accelerators. Background Technology

[0002] Accelerator CBS is also known as accelerator CZ or N-cyclohexyl-2-benzothiazole sulfenamide.

[0003] Currently, the commonly used production processes employ sodium hypochlorite oxidation or hydrogen peroxide oxidation. Generally, before the reaction begins, chlorine gas is passed into a sodium hydroxide solution at a low temperature (below 20°C) to prepare sodium hypochlorite. A certain amount of recovered cyclohexylamine is placed in the reaction vessel, and accelerator M is added under stirring. Sodium hypochlorite solution is then added dropwise at a measured rate under low temperature. TLC monitoring is performed until the reaction reaches its endpoint, at which point the solution is filtered. The filtrate can be rotary evaporated to recover cyclohexylamine, and the resulting solid, after drying, becomes accelerator CZ. While sodium hypochlorite as an oxidant simplifies the process, it generates a significant amount of wastewater. Hydrogen peroxide oxidation produces almost no wastewater and has a higher conversion efficiency, but it requires more equipment and has a correspondingly higher processing cost. Therefore, small and medium-sized enterprises often prioritize sodium hypochlorite oxidation for rubber accelerator preparation, only needing to treat the subsequent wastewater.

[0004] Existing methods for treating wastewater from the oxidation of sodium hypochlorite to produce rubber accelerators employ evaporation or coagulation. As the names suggest, one relies on vaporization, and the other on sedimentation. In vaporization, high-pressure steam is used to precipitate salt. This process typically consists of a liquid distribution device, a heated evaporation chamber, and a vapor-liquid separation chamber. The working principle involves the material to be evaporated and concentrated flowing downwards within heat exchange tubes, exchanging heat with the heating medium outside the tubes to achieve the evaporation and concentration process. However, existing technology suffers from a problem: the diffusion path of the heating medium after entering the heat exchanger is uncontrollable, resulting in uneven heat exchange between the heating medium and the liquid film of the material to be treated formed on the inner wall of each heat exchange tube, severely impacting heat exchange efficiency. This issue is also raised in Chinese Patent No. CN208022728U, which uses a first overflow trough and a first overflow plate to direct the liquid to a second overflow... The liquid flows horizontally above the tank, then enters the heat exchange tubes through a second overflow tank. High-pressure hot air is then introduced into the side of the tank and distributed to the outer wall of the heat exchange tubes to exchange heat with the inner wall. Although the liquid forms a liquid film when heated within the heat exchange tubes, increasing heat exchange efficiency, directly introducing the liquid into the inner wall requires a preheating period. During this preheating, a salt film easily forms at the liquid film in the heat exchange tubes, hindering the efficiency of water intake. Furthermore, during the final stage of wastewater treatment, when the liquid enters the liquid film in the heat exchange tubes, the upper inlet valve needs to be closed, and the device requires a cooling period. This natural cooling method results in low salt precipitation efficiency and also easily forms a salt film at the liquid film in the heat exchange tubes. When not in production, the tank is difficult to open for cleaning, and during production, it further hinders water intake into the heat exchange tubes. Therefore, we propose a wastewater treatment device for CBS (Chemical Bioassay Synthetic Acid) rubber accelerator. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment device for CBS rubber accelerator, comprising a treatment tank and a spliced ​​bottom tank connected to the bottom of the treatment tank via a flange. An inlet pipe is provided in the middle of the outer wall of the treatment tank, and an outlet pipe is spliced ​​at the center of the bottom of the bottom tank. A pair of hot air inlet pipes are installed at the bottom of the spliced ​​bottom tank. A fixing plate is installed at the top inside the treatment tank, and multiple hollow cooling pipes are installed at the bottom of the fixing plate. A sliding rod is installed at the bottom of the fixing plate, and one end of the sliding rod is connected to a cleaning assembly for sliding connection with the fixing plate. The other end of the sliding rod... A floating rack is provided; the cleaning assembly includes a perforated lifting plate that slides on multiple hollow cooling pipes, the perforated lifting plate having openings with an aperture larger than the outer diameter of the hollow cooling pipes, multiple annular scrapers located on the inner ring of each opening and in contact with each hollow cooling pipe, openings in the openings, and connecting pipes located on the outer ring of the perforated lifting plate communicating with the interior of the processing tank through the openings; cold air inlet pipes and cold air outlet pipes are respectively installed on the outside of the processing tank with the processing tank axis as the center of symmetry, and multiple baffles are respectively installed between the top of the processing tank and the top of the fixed plate, and Two adjacent baffles are horizontally offset from each other. The hollow cooling pipe is connected to the cold air inlet pipe through the baffles. A motor is installed at the center of the top of the treatment tank. A housing is fitted around the output shaft of the motor. A drain outlet is provided between the fixed plate and the hollow lifting plate of the housing. A water inlet is provided at the bottom of the housing near the water outlet pipe. A spiral blade rotating inside the housing is installed at the bottom of the motor output shaft. An anti-backflow cavity is installed between the inner wall of the treatment tank and the water inlet pipe. The top of the anti-backflow cavity contacts the bottom of the fixed plate and communicates with the treatment tank. The exterior of the treatment tank... A climbing assembly for raising and lowering the perforated lifting plate is installed on the side opposite to the anti-backflow chamber and the axis of the treatment tank. The climbing assembly includes a telescopic column on the outer ring of the perforated lifting plate, a limiting ring on the outer ring of the treatment tank, a sealing shell on the outside of the treatment tank for covering the limiting ring, and climbing teeth on one side of the sealing shell located at the center of the limiting ring. The climbing teeth are provided with multiple equidistant climbing grids with upward inclined surfaces, and the telescopic column and the climbing grids abut against each other. The telescopic column is made of two sleeves with matching large and small diameters, and a spring is installed inside the telescopic column and connected to the small diameter sleeve.

[0007] Preferably, a corrugated pipe box connected to a connecting pipe is installed outside the processing tank. A section of corrugated pipe is installed inside the corrugated pipe box and connected to the connecting pipe. A fixed pipe is installed outside the corrugated pipe box. A vortex tube is installed at one end of the fixed pipe. The other end of the vortex tube is connected to the hot gas inlet pipe through a pipeline.

[0008] Preferably, a receiving mesh is installed in the middle of the outer casing that is sleeved on the outside of the motor output shaft, and the receiving mesh and the outer casing are slidably connected. A hot air outlet pipe is installed on the outside of the processing tank near the bottom of the receiving mesh.

[0009] Preferably, the highest point of the hot air inlet pipe is installed at the same height as the axis of the water inlet pipe.

[0010] Preferably, the top of the hollow cooling pipe and the fixing plate are connected together by threads.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This invention uses high-pressure gas to drive the hollow lifting plate to rise and fall. The annular scraper at the opening of the hollow lifting plate rubs against the hollow cooling pipe to remove salt frost. This ensures that the outer wall of the hollow cooling pipe can be continuously used during the desalination process. Furthermore, the water intake efficiency is not hindered by the motor-driven spiral blade rotation. The device can introduce cold air into the hollow cooling pipe, accelerating the desalination efficiency. In addition, the device can be spliced ​​with a processing tank and a bottom tank flange, which facilitates internal cleaning and increases performance.

[0013] 2. The hollow lifting plate of this invention climbs on the climbing teeth via a telescopic column and descends rapidly when it is at the top of the climbing teeth. This is to control the hot gas pressure and achieve a constant hot gas pressure to control the amount of salt precipitation in the hollow cooling pipe. Controlling the lifting of the hollow lifting plate also helps to prevent the upper part of the hollow lifting plate from sliding down the slide bar to the bottom of the treatment tank when it comes into contact with water, which would require a large amount of gas to lift the hollow lifting plate.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-8 This invention provides a technical solution: a wastewater treatment device for CBS (a rubber accelerator), comprising a treatment tank 1 and a spliced ​​bottom tank 2 connected to the bottom of the treatment tank 1 via a flange. The device includes an inlet pipe 3 located in the middle of the outer wall of the treatment tank 1 and an outlet pipe 201 located at the center of the bottom of the spliced ​​bottom tank 2. A pair of hot air inlet pipes 4 are installed at the bottom of the spliced ​​bottom tank 2. A fixing plate 13 is installed at the top inside the treatment tank 1. Multiple hollow cooling pipes 16 are installed at the bottom of the fixing plate 13. A sliding rod is installed at the bottom of the fixing plate 13. One end of the sliding rod is connected to a cleaning assembly for sliding connection with the fixing plate 13, and the other end of the sliding rod is fitted with a floating shelf 11. The cleaning assembly includes a hollow lifting mechanism that slides on the multiple hollow cooling pipes 16. The plate 14 has multiple openings on the hollow lifting plate 14 with a diameter larger than the outer diameter of the hollow cooling pipe 16, multiple annular scrapers 1402 in contact with each hollow cooling pipe 16 on the inner ring of each opening, openings 1403 on the openings, and connecting pipes 1401 on the outer ring of the hollow lifting plate 14 that communicate with the inside of the processing tank 1 through the openings 1403; cold air inlet pipes 8 and cold air outlet pipes 801 are respectively installed on the outside of the processing tank 1 with the axis of the processing tank 1 as the center of symmetry; multiple baffles 15 are respectively installed between the top of the processing tank 1 and the top of the fixed plate 13, and adjacent baffles 15 are staggered in the horizontal direction; the hollow cooling pipe 16 communicates with the cold air inlet pipes 8 through the baffles 15.

[0025] Example 1: This device first injects water into the inlet pipe 3. After the wastewater is injected, it flows into the spliced ​​bottom tank 2, and the float 11 floats on the water surface (the outlet pipe 201 is in a closed state). Then, the air pump connected to the hot air inlet pipe 4 is turned on, and the air pump injects high-pressure hot air into the hot air inlet pipe 4. The high-pressure hot air generates bubbles and causes the wastewater on the spliced ​​bottom tank 2 to churn. When the wastewater churns, part of the wastewater is converted into gas, and the water vapor rises with the high-pressure gas. As hot air continues to enter, the gas passes through the float 11 to the bottom of the hollow lifting plate 14. After the gas accumulates for a certain period of time, it pushes the hollow lifting plate 14 upward and slides along the slide bar, cooling the hollow part. A portion of tube 16 is exposed to contact with hot air, and then cold air is introduced through the cold air inlet pipe 8. After the cold air enters the inner wall of the hollow cooling tube 16, it is used to cool the hollow cooling tube 16. At this time, the hot air is located on the outer wall of the hollow cooling tube 16, and water vapor exchanges heat on the hollow cooling tube 16, and then a small amount of salt frost is formed on the hollow cooling tube 16. Then the amount of hot air introduced through the hot air inlet pipe 4 is gradually reduced, and the inside of the treatment tank 1 can be cooled quickly. In this way, the perforated lifting plate 14 can be lowered quickly. The perforated lifting plate 14 uses the annular scraper 1402 at its opening to rub the hollow cooling tube 16 and scrape off the salt frost. Then the water is heated and the process is repeated to complete the desalination work.

[0026] Example 2: In order to ensure the continuity of water intake and enhance desalination efficiency, a motor 7 is installed at the center of the top of the treatment tank 1. The output shaft of the motor 7 is covered with a housing. The housing has a drain outlet 701 between the fixed plate 13 and the hollow lifting plate 14. The housing has a suction outlet 702 at the bottom near the water outlet pipe 201. A spiral blade 703 rotating in the inner circle of the housing is installed at the bottom of the output shaft of the motor 7.

[0027] When the water is on the bottom tank 2, the motor 7 can be turned on first. When the output shaft of the motor 7 rotates, a small amount of water is introduced from the water inlet 702 to the drain outlet 701 through the rotation of the spiral blade 703, filling the top of the hollow lifting plate 14 with water. The water filling the top of the hollow lifting plate 14 will spread the water flow evenly to the outer wall of each hollow cooling pipe 16. Then, cold air is introduced into the cold air inlet pipe 8. After passing through multiple layers of obstruction by the baffle 15, the cold air is more easily and longer retained on the inner wall of the hollow cooling pipe 16 (cold air mass downward). Then, hot air is injected into the hot air inlet pipe 4 to drive the hollow lifting plate 14 to rise. When plate 14 rises, hot air enters from the side of the treatment tank 1 between the fixed plate 13 and the hollow lifting plate 14, and then exchanges heat with the water at the inner and outer walls of the hollow cooling pipe 16. After the water vaporizes or partially vaporizes between the fixed plate 13 and the hollow lifting plate 14, the input of hot air is reduced, causing salt frost to form on the outer wall of the hollow cooling pipe 16. The input of hot air is increased again, increasing the internal pressure of the treatment tank 1, raising the hollow lifting plate 14, and scraping the salt frost on the outside of the hollow cooling pipe 16 to the bottom. Then, the motor 7 continues to drive the spiral blade 703 to rotate and inject water between the fixed plate 13 and the hollow lifting plate 14, and the device enters the circulation again.

[0028] The processing tank 1 is equipped with a corrugated pipe box 9 that is connected to the connecting pipe 1401. A section of corrugated pipe is installed inside the corrugated pipe box 9 and is connected to the connecting pipe 1401. A fixed pipe 6 is installed outside the corrugated pipe box 9. A vortex pipe 5 is installed at one end of the fixed pipe 6. One end of the vortex pipe 5 is connected to the hot gas inlet pipe 4 through a pipe.

[0029] During implementation, by installing a bellows and a filter screen in the bellows box 9, when the perforated lifting plate 14 is raised and lowered, high-pressure hot air (such as...) from the side of the treatment tank 1 will enter through the opening 1403 on the perforated lifting plate 14. Figure 4 As can be seen, when high-pressure gas enters through opening 1403, the high-pressure gas will form a vortex inside the perforated lifting plate 14, scraping off some of the salt frost and then entering the perforated lifting plate 14 through opening 1403 and then into the corrugated pipe inside the corrugated pipe box 9. A filter screen is installed at one end of the corrugated pipe to filter the salt frost. Then, the high-pressure air passes through the filter screen and enters the fixed pipe 6 and then enters the vortex pipe 5. Due to the characteristics of the vortex pipe 5, when facing high-pressure gas, one end generates cold air and the other end generates hot air. Connecting the end that generates hot air to the hot air inlet pipe 4 can preheat the water circulation, while the end that generates cold air can cool the room and achieve a comfortable working environment.

[0030] An anti-backflow cavity 301 is installed on the inner wall of the treatment tank 1 between it and the water inlet pipe 3. The top of the anti-backflow cavity 301 contacts the bottom of the fixing plate 13 and communicates with the treatment tank 1. A climbing component for lifting the hollow lifting plate 14 is installed on the outside of the treatment tank 1 on the side opposite to the anti-backflow cavity 301 with the axis of the treatment tank 1.

[0031] The contact between the top of the anti-backflow chamber 301 and the fixing plate 13 can keep the treatment tank 1 in a sealed state when heating gas, preventing gas from directly entering the water inlet pipe 3 during heating, causing backflow and impacting the pipe opening.

[0032] The climbing assembly includes a telescopic column 17 located on the outer ring of the hollow lifting plate 14, a limiting ring 18 located on the outer ring of the processing tank 1, a sealing shell located outside the processing tank 1 and used to cover the limiting ring 18, and climbing teeth 19 located on one side of the sealing shell at the center of the limiting ring 18. The climbing teeth 19 are provided with multiple equidistant climbing grids with upward inclined surfaces, and the telescopic column 17 and the climbing grids abut against each other. The telescopic column 17 is made of two sleeves with matching large and small diameters, and a spring is installed inside the telescopic column 17 and connected to the small diameter sleeve.

[0033] enter Figure 4 It is known that high-pressure gas can enter the climbing assembly and then enter between the fixed plate 13 and the hollow lifting plate 14. When the hollow lifting plate 14 rises, it will extend and retract through the climbing teeth 19 via the telescopic column 17. When the telescopic column 17 is at a certain height of the climbing teeth 19, the hot gas pressure is stabilized and the hollow lifting plate 14 stops rising, so as to control the hot gas pressure. When the hot gas pressure is constant, the amount of salt precipitation in the hollow cooling pipe 16 is reduced. Controlling the rise and fall of the hollow lifting plate 14 also helps to prevent the upper part of the hollow lifting plate 14 from sliding down the slide bar to the bottom of the treatment tank 1 when it comes into contact with water, so that the equipment needs a large amount of gas to lift the hollow lifting plate 14.

[0034] A receiving mesh 12 is installed in the middle of the outer ring of the outer casing that is sleeved on the output shaft of the motor 7, and the receiving mesh 12 is slidably connected to the outer casing. A hot air outlet pipe 10 is installed on the outside of the processing tank 1 near the bottom of the receiving mesh 12. The receiving mesh 12 is conducive to receiving the salt crystals scraped off from the top. After the salt crystals fill the receiving mesh 12, the processing tank 1 can be separated from the spliced ​​bottom tank 2 to clean the receiving mesh 12.

[0035] The highest point of the hot air inlet pipe 4 is installed at the same height as the axis of the water inlet pipe 3. This creates a communicating vessel effect, preventing water from flowing back into the hot air inlet pipe and thus reducing the bubble generation effect.

[0036] The top of the hollow cooling pipe 16 and the fixing plate 13 are connected together by threads, making it easy to remove for inspection and replacement.
