Description

Technical Field

[0001] This invention relates to the field of reagent dosing devices, specifically to a reagent dosing device and production process for treating wastewater from the production of hexafluoroethanepropanol. Background Technology

[0002] Hexafluoroethane propanol is an important fluorinated fine chemical widely used in chemical, electronic, and pharmaceutical fields. Among them, the dosing of the agent is a core link in the wastewater treatment process, and the performance of the device directly affects the treatment effect.

[0003] Patent CN220310198U discloses a chemical agent dosing device for wastewater treatment, including a wastewater tank. Through the cooperation of a mixing mechanism, a feeding mechanism, and a control panel, wastewater treatment agents are filled into storage chambers via a feed pipe. Each storage chamber has the same capacity. Based on the wastewater volume in the tank, the control panel controls the opening of the corresponding first solenoid valve to add the wastewater treatment agent into the tank, avoiding excessive or insufficient agent addition and thus preventing waste. A drive motor rotates the main shaft, which in turn drives the auxiliary gears of four sets of rotating secondary shafts via a synchronous chain. This allows five sets of stirring components to mix the wastewater and agents, improving the mixing efficiency. Furthermore, a lifting plate facilitates the upward movement of wastewater from the bottom, reducing the time required for uniform mixing and improving the wastewater treatment effect. However, this device is prone to contamination when adding agents to wastewater, making it difficult to guarantee wastewater treatment efficiency. Therefore, a wastewater treatment agent dosing device and production process for producing hexafluoroethanepropanol is proposed to address these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device for adding wastewater treatment agents in the production of hexafluoroethanepropanol and a production process, in order to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a reagent dosing device for wastewater treatment in the production of hexafluoroethanepropanol, comprising a reagent box, a reagent outlet fixedly connected to the front side of the reagent box, a reciprocating screw rod rotatably connected to the inner wall of the reagent box, a fixing block fixedly connected to the inner wall of the reagent box, a reciprocating screw rod 2 fixedly connected to the rear side of the fixing block, a reagent inlet box movably connected to the circumferential surface of the reciprocating screw rod 2, an opening in the inner wall of the reagent inlet box, a fixing column fixedly connected to the inner wall of the reciprocating screw rod 1, and a fixing column rotatably connected to the front side of the fixing column. A piston plate is fixedly connected to the reciprocating screw. The circumferential surface of the reciprocating screw is equipped with an agitation mechanism for stirring the medicine, and a capture mechanism for capturing impurities in the medicine. An inlet is provided on the inner wall of the reciprocating screw. When wastewater enters the wastewater tank, the reciprocating screw drives the medicine into the inner wall of the inlet tank. Once inside, the medicine continues to move, separating it from external medicine. Finally, the medicine inside the inlet tank is sprayed to prevent further contact with external medicine and to avoid damage to the medicine. Pollution is reduced, and the purification efficiency of the agent on wastewater is improved, allowing for more precise dosing and better control of the dosage. A one-way valve is installed on the inner wall of the inlet tank, and a sliding groove is formed on the inner wall of the reciprocating screw. A motor is fixedly connected to the rear side of the agent box, and the rear side of the reciprocating screw is fixedly connected to the output end of the motor. When the agent enters the inlet tank, the inlet tank, in conjunction with the piston plate, drives the internal pressure to open the one-way valve, allowing the agent to flow out. This achieves indirect dispensing from the inlet tank, preventing the agent from being dispensed incorrectly during the dosing process. The occurrence of backflow or reverse flow helps to ensure the stability and accuracy of the drug during the dosing process, avoids equipment damage or drug waste caused by drug backflow, improves the accuracy of drug dosing, and reduces drug waste; the circumferential surface of the drug inlet box contacts the inner wall of the reciprocating screw, the drug inlet box contacts the inner wall of the sliding groove, and the drug inlet box will move along the inner wall of the sliding groove; the fixed column contacts the inner wall of the drug inlet box; the piston plate contacts the inner wall of the drug inlet box; and the one-way valve will dispense the drug in one direction through the one-way pressure of the piston plate.

[0006] Preferably, the stirring mechanism includes an inner ring, a rotating rod rotatably connected to the inner wall of the inner ring, and stirring blades fixedly connected to the circumferential surface of the rotating rod. An outer ring is slidably connected to the inner wall of the medicine box, and a sliding groove is formed on the inner wall of the outer ring. A limit rod is fixedly connected to the inner wall of the medicine box. While the medicine is being dispensed, the reciprocating screw drives the stirring blades to agitate the medicine, accelerating the thorough mixing of the medicine, thereby improving its solubility and ensuring its more effective action. It also allows the medicine to distribute more quickly, avoiding excessively high local concentrations and improving the medicine's efficacy. Rollers are fixedly connected to the circumferential surface of the rotating rod, and a limit rod is fixedly connected to the inner wall of the medicine box. The fixed sleeve, while agitating, uses a rotating rod to drive the agitating blades to rotate and agitate the solution. The agitation of the blades helps disperse the particles, increases the contact area between the agent and the contaminants, improves removal efficiency, effectively prevents bubble accumulation and dead zones, helps accelerate the reaction rate, improves reaction efficiency, and thus improves the treatment effect. The circumferential surface of the reciprocating screw is movably connected to the inner wall of the inner ring, the circumferential surface of the rotating rod is rotatably connected to the inner wall of the outer ring, the inner wall of the sliding groove is in contact with the outer surface of the limiting rod, and the limiting rod limits the outer ring. The circumferential surface of the roller is in contact with the inner wall of the fixed sleeve, and the circumferential surface of the roller is in contact with and rubs against the inner wall of the fixed sleeve.

[0007] Preferably, the capturing mechanism includes a connecting plate, a fixing frame fixedly connected to the outer surface of the connecting plate, and a capturing plate fixedly connected to the inner wall of the fixing frame. While the agent is being agitated, the reciprocating screw rotates, causing the capturing plate to capture impurities in the agent. This effectively removes impurities, ensuring the purity and quality of the agent. Pure agents maximize their effectiveness in water treatment or other applications, preventing impurities from affecting the agent's reaction or performance, and further improving the purification effect on wastewater. A rotating ring is rotatably connected to the inner wall of the outer ring, and a telescopic hinge rod is hinged to the side of the rotating ring away from the outer ring. A hinge block is hinged to one side of the rotating ring. A scraper is slidably connected to the inner wall of the fixed frame. A sliding groove three is opened on the inner wall of the fixed frame. While filtering the agent, the scraper is driven by the outer ring to clean the outer surface of the capture plate, which can ensure that the surface is kept clean and maintain its optimal capture effect, thereby improving the overall working efficiency, reducing the occurrence of failures, reducing subsequent maintenance costs, and improving the stability of the equipment. A connecting plate is fixedly connected to the circumferential surface of the reciprocating screw. The hinge block is in contact with the inner wall of the sliding groove three. The scraper is fixedly connected to the hinge block on the side near the sliding groove three. The scraper is in contact with the outer surface of the capture plate.

[0008] A production process for a wastewater treatment agent dosing device for hexafluoroethanepropanol production includes the following steps: Step 1: When sewage enters the sewage tank, first install the reagent box on the sewage tank, and then have the staff add the reagent to the reagent box; Step 2: Then manually start the motor on the back of the medicine box. The motor will drive the reciprocating screw to rotate, which in turn drives the sliding groove to rotate. The rotating sliding groove contacts the medicine box through the inner wall, thereby driving the medicine box to rotate. Step 3: The medicine feeding box rotates because the inner wall contacts the circumferential surface of the reciprocating screw two. The reciprocating screw two rotates through the limiting part of the fixed block. At this time, it will contact the medicine feeding box through the reciprocating sliding groove on the circumferential surface of the reciprocating screw two, thereby driving the medicine feeding box to move back and forth. Step 4: The opening of the container moves back and forth to contact the inlet, so that the opening and the inlet coincide, allowing the medicine to enter the inner wall of the container. After the medicine enters the container, it continues to move, thus separating from the medicine outside. Finally, the medicine inside the container is sprayed.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This device and process for dispensing chemicals for the treatment of hexafluoroethanepropanol production wastewater utilizes the coordinated operation of a chemical box, outlet, fixed block, reciprocating screw one, reciprocating screw two, inlet box, inlet, box opening, fixed column, piston plate, slide groove one, and one-way valve. When wastewater enters the wastewater tank, the reciprocating screw one drives the chemical into the inner wall of the inlet box. Once inside, the chemical continues to move, separating from external chemicals. Finally, the chemical inside the inlet box is sprayed to prevent further contact with external chemicals and to avoid chemical contamination. The system effectively reduces pollution and improves the purification efficiency of the chemicals for wastewater, allowing for more precise dosage and better control of the dosage. When the chemicals enter the inlet tank, the inlet tank, in conjunction with the piston plate, drives the internal pressure to open the one-way valve, allowing the chemicals to flow out. This achieves indirect dispensing from the inlet tank, preventing backflow or reverse flow during the dosing process. This helps ensure the stability and accuracy of the chemicals during dosing, avoiding equipment damage or waste caused by backflow, thus improving the precision of chemical dosing and reducing waste.

[0010] 2. This wastewater treatment agent dosing device and production process for hexafluoroethane propanol production utilizes the coordinated operation of an inner ring, rotating rod, stirring blades, outer ring, limiting rod, and chute two. Simultaneously with agent dosing, the reciprocating screw drives the stirring blades to agitate the agent, accelerating its thorough mixing and improving its solubility. This ensures the agent functions more effectively and distributes more rapidly, preventing excessively high local concentrations and enhancing its overall efficacy.

[0011] 3. The device and process for adding chemicals to treat wastewater from the production of hexafluoroethanepropanol utilizes the coordinated operation of rollers and a fixed sleeve. While stirring, a rotating rod drives the stirring blades to rotate and agitate the chemical solution. The stirring of the blades helps disperse the particles, increases the contact area between the chemical and the pollutants, improves removal efficiency, effectively prevents bubble accumulation and dead zones, helps accelerate the reaction rate, improves reaction efficiency, and thus enhances the treatment effect.

[0012] 4. This wastewater treatment agent dosing device and production process for hexafluoroethanepropanol production utilizes the coordinated operation of a connecting plate, a fixed frame, and a capture plate. While the agent is being agitated, the reciprocating screw rotates, causing the capture plate to capture impurities in the agent. This effectively removes impurities, ensuring the purity and quality of the agent. Pure agents maximize their effectiveness in water treatment or other applications, preventing impurities from affecting the agent's reaction or performance, and further improving the wastewater purification effect.

[0013] 5. This wastewater treatment agent dosing device and production process for hexafluoroethane propanol production utilizes the coordinated operation of a rotating ring, a telescopic hinge rod, a hinge block, a scraper, and a chute. While filtering the agent, the outer ring drives the scraper to clean the outer surface of the capture plate, ensuring its cleanliness and maintaining optimal capture performance. This improves overall work efficiency, reduces malfunctions, lowers subsequent maintenance costs, and enhances equipment stability. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1-8 One embodiment of the present invention is: a reagent dispensing device for treating wastewater from hexafluoroethanepropanol production, comprising a reagent box 1, a reagent outlet 2 fixedly connected to the front side of the reagent box 1, a reciprocating screw 4 rotatably connected to the inner wall of the reagent box 1, a fixing block 3 fixedly connected to the inner wall of the reagent box 1, a reciprocating screw 7 fixedly connected to the rear side of the fixing block 3, a reagent inlet box 8 movably connected to the circumferential surface of the reciprocating screw 7, and an opening 10 on the inner wall of the reagent inlet box 8. A fixed column 11 is fixedly connected to the inner wall of the reciprocating screw 4, and a piston plate 12 is fixedly connected to the front side of the fixed column 11. An agitation mechanism 5 for agitating the medicine is provided on the circumferential surface of the reciprocating screw 4. A capture mechanism 6 for capturing impurities in the medicine is provided on the circumferential surface of the reciprocating screw 4. A medicine inlet 9 is opened on the inner wall of the reciprocating screw 4. A one-way valve 14 is installed on the inner wall of the medicine inlet box 8. A sliding groove 13 is opened on the inner wall of the reciprocating screw 4. When wastewater enters the wastewater tank, the medicine box 1 is first installed on the wastewater tank. Then, the staff adds the medicine to the medicine box 1. The motor on the back of the medicine box 1 is then manually started. The motor drives the reciprocating screw 4 to rotate, which in turn drives the sliding groove 13 to rotate. The sliding groove 13 rotates and contacts the medicine inlet box 8 through its inner wall, thus causing the medicine inlet box 8 to rotate. The medicine inlet box 8 rotates because its inner wall contacts the circumferential surface of the reciprocating screw 7. The reciprocating screw 7 rotates through the limiting part of the fixing block 3. At this time, the medicine inlet box 8 rotates through the circumferential surface of the reciprocating screw 7. The sliding groove contacts the inlet tank 8, causing the inlet tank 8 to move back and forth. The inlet tank 8 drives the tank opening 10 to move back and forth until it contacts the inlet 9, allowing the inlet tank 10 to overlap with the inlet 9, so that the medicine enters the inner wall of the inlet tank 8. After the medicine enters the inlet tank 8, it continues to move, thus separating from the external medicine. Finally, the medicine inside the inlet tank 8 is sprayed to avoid further contact with the external medicine and prevent contamination. This improves the purification efficiency of the medicine for wastewater, allows for more precise dosing of the medicine, and better controls the dosage. A motor is fixedly connected to the rear side of the medicine box 1, and the rear side of the reciprocating screw 4 is fixedly connected to the output end of the motor; the circumferential surface of the medicine inlet box 8 contacts the inner wall of the reciprocating screw 4, the medicine inlet box 8 contacts the inner wall of the sliding groove 13, and the medicine inlet box 8 will move along the inner wall of the sliding groove 13; the fixed column 11 contacts the inner wall of the medicine inlet box 8; the piston plate 12 contacts the inner wall of the medicine inlet box 8; and the one-way valve 14 will dispense medicine in one direction through the one-way pressure of the piston plate 12. When the medicine enters the medicine inlet 8, the forward movement of the medicine inlet 8 will cause the opening 10 to move forward as well. The opening 10 moves forward and overlaps with the medicine inlet 9, allowing the medicine to enter. When the medicine inlet 8 moves backward, the medicine inside the medicine inlet 8 will come into contact with the piston plate 12, causing the piston plate 12 to squeeze the medicine out. At this time, the piston plate 12 will drive the internal pressure to open the valve of the one-way valve 14 and let the medicine flow out from the medicine outlet 2. When the medicine inlet 8 leaves, the one-way valve 14 will close, thus realizing the indirect dispensing of medicine from the medicine inlet 8. This prevents the medicine from flowing back or flowing backward during the dispensing process, helps to ensure the stability and accuracy of the medicine during the dispensing process, avoids equipment damage or medicine waste caused by medicine backflow, improves the accuracy of medicine dispensing, and reduces medicine waste.

[0018] Working principle: When sewage enters the sewage tank, the reciprocating screw 4 drives the agent into the inner wall of the inlet tank 8. After entering the inlet tank 8, the agent continues to move, thus separating from the external agent. Finally, the agent inside the inlet tank 8 is sprayed, avoiding further contact with the external agent and preventing contamination, thereby improving the purification efficiency of the agent for sewage. When the agent enters the inside of the inlet tank 8, the inlet tank 8, in conjunction with the piston plate 12, drives the internal pressure to open the valve port of the one-way valve 14, thus realizing the indirect dispensing of the agent from the inlet tank 8. This prevents backflow or reverse flow of the agent during the dosing process, helping to ensure the stability and accuracy of the agent during the dosing process.

[0019] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the stirring mechanism 5 includes an inner ring 51, a rotating rod 52 is rotatably connected to the inner wall of the inner ring 51, a stirring blade 53 is fixedly connected to the circumferential surface of the rotating rod 52, an outer ring 54 is slidably connected to the inner wall of the medicine box 1, a sliding groove 58 is provided on the inner wall of the outer ring 54, and a limit rod 55 is fixedly connected to the inner wall of the medicine box 1. While the agent is being dispensed, the reciprocating screw 4 rotates and contacts the inner wall of the inner ring 51 through the reciprocating sliding groove on the circumferential surface, thereby driving the inner ring 51 to move back and forth. The inner ring 51 drives the rotating rod 52 to move back and forth, and the rotating rod 52 drives the stirring blade 53 to move back and forth. The reciprocating movement of the stirring blade 53 stirs the agent inside the agent box 1. The stirring blade 53 stirs the agent, which can accelerate the full mixing of the agent, thereby improving the solubility of the agent and ensuring that the agent can play a more effective role. It can also make the agent distribute more quickly, avoid excessively high local agent concentration, and improve the effect of the agent. A roller 56 is fixedly connected to the circumferential surface of the rotating rod 52, and a fixed sleeve 57 is fixedly connected to the inner wall of the medicine box 1; the circumferential surface of the reciprocating screw 4 is movably connected to the inner wall of the inner ring 51, the circumferential surface of the rotating rod 52 is rotatably connected to the inner wall of the outer ring 54, the inner wall of the sliding groove 58 is in contact with the outer surface of the limiting rod 55, and the limiting rod 55 will limit the outer ring 54; the circumferential surface of the roller 56 is in contact with the inner wall of the fixed sleeve 57, and the circumferential surface of the roller 56 is in contact with and rubs against the inner wall of the fixed sleeve 57; While agitating, the inner ring 51 reciprocates, driving the rotating rod 52 to reciprocate. The rotating rod 52 drives the roller 56 to reciprocate. The roller 56 moves and contacts the inner wall of the fixed sleeve 57 through its circumferential surface, thereby causing the roller 56 to rotate. The roller 56 drives the rotating rod 52 to rotate, which in turn drives the agitating blade 53 to rotate. This causes the agitating blade 53 to rotate and agitate the solution. The agitation of the blades helps to disperse these particles, increases the contact area between the agent and the pollutants, improves the removal efficiency, effectively prevents the accumulation of bubbles and the formation of dead zones, helps to accelerate the reaction rate, improves the reaction efficiency, and thus improves the treatment effect.

[0020] Working principle: While the agent is being added, the reciprocating screw 4 drives the stirring blade 53 to stir the agent, which accelerates the thorough mixing of the agent, thereby improving the solubility of the agent and ensuring that the agent can play a more effective role. At the same time, the rotating rod 52 drives the stirring blade 53 to rotate and stir the liquid. The stirring of the blades helps to disperse the particles, increase the contact area between the agent and the pollutants, and improve the removal efficiency.

[0021] The capturing mechanism 6 includes a connecting plate 61, a fixing frame 62 is fixedly connected to the outer surface of the connecting plate 61, and a capturing plate 63 is fixedly connected to the inner wall of the fixing frame 62. While the agent is being stirred, the reciprocating screw 4 rotates, causing the connecting plate 61 to rotate. The connecting plate 61 then rotates the fixing frame 62, which in turn rotates the capturing plate 63. This allows the capturing plate 63 to capture impurities in the agent, effectively removing them and ensuring the purity and quality of the agent. Pure agents can maximize their effectiveness in water treatment or other applications, preventing impurities from affecting the agent's reaction or performance, and further improving the purification effect on wastewater. A rotating ring 64 is rotatably connected to the inner wall of the outer ring 54. A telescopic hinge rod 65 is hinged to the side of the rotating ring 64 away from the outer ring 54. A hinge block 66 is hinged to the side of the telescopic hinge rod 65 away from the rotating ring 64. A scraper 67 is slidably connected to the inner wall of the fixed frame 62. A sliding groove 68 is opened on the inner wall of the fixed frame 62. A connecting plate 61 is fixedly connected to the circumferential surface of the reciprocating screw 4. The hinge block 66 contacts the inner wall of the sliding groove 68. The scraper 67 is fixedly connected to the hinge block 66 on the side of the scraper 67 near the sliding groove 68. The scraper 67 contacts the outer surface of the capture plate 63.

[0022] A production process for a wastewater treatment agent dosing device for hexafluoroethanepropanol production includes the following steps: Step 1: When the sewage enters the sewage tank, first install the agent box 1 onto the sewage tank, and then have the staff add the agent into the agent box 1. Step 2: Then manually start the motor on the back of the medicine box 1. The motor will drive the reciprocating screw 4 to rotate, which in turn drives the sliding groove 13 to rotate. The rotating sliding groove 13 contacts the medicine inlet box 8 through its inner wall, thereby driving the medicine inlet box 8 to rotate. Step 3: The medicine feeding box 8 rotates because its inner wall contacts the circumferential surface of the reciprocating lead screw 7. The reciprocating lead screw 7 rotates through the limiting part of the fixing block 3. At this time, it will contact the medicine feeding box 8 through the reciprocating sliding groove of the circumferential surface of the reciprocating lead screw 7, thereby driving the medicine feeding box 8 to move back and forth. Step 4: The opening 10 moves back and forth to contact the inlet 9, so that the opening 10 and the inlet 9 coincide, allowing the medicine to enter the inner wall of the medicine inlet box 8. After the medicine enters the medicine inlet box 8, it continues to move, thereby separating from the external medicine. Finally, the medicine inside the medicine inlet box 8 is sprayed. While filtering the agent, the capture plate 63 rotates, causing the scraper 67 to rotate. The scraper 67 then rotates the hinge block 66, which in turn rotates the telescopic hinge rod 65. The telescopic hinge rod 65 then rotates the rotating ring 64. Simultaneously, the reciprocating movement of the outer ring 54 drives the telescopic hinge rod 65 to reciprocate through the hinge point. This reciprocating movement of the telescopic hinge rod 65, in turn, drives the hinge block 66 to reciprocate through the hinge point. The hinge block 66 then drives the scraper 67 to reciprocate. This process cleans the outer surface of the capture plate 63, ensuring its cleanliness and maintaining optimal capture performance. This improves overall work efficiency, reduces malfunctions, lowers subsequent maintenance costs, and enhances equipment stability.

[0023] Working principle: While agitating the reagent, the reciprocating screw 4 rotates to drive the capture plate 63 to capture impurities in the reagent, which can effectively remove impurities, ensure the purity and quality of the reagent, and further improve the purification effect of wastewater. While filtering the reagent, the outer ring 54 drives the scraper 67 to clean the outer surface of the capture plate 63, which can ensure that its surface is kept clean and maintain its optimal capture effect, thereby improving the overall working efficiency.

9. The device for adding reagents to treat wastewater from hexafluoroethanepropanol production according to claim 8, characterized in that: A connecting plate (61) is fixedly connected to the circumferential surface of the reciprocating screw (4), the hinge block (66) is in contact with the inner wall of the sliding groove (68), the scraper (67) is fixedly connected to the hinge block (66) on the side near the sliding groove (68), and the scraper (67) is in contact with the outer surface of the capture plate (63).

10. A production process for a wastewater treatment agent dosing device for hexafluoroethanepropanol production, employing the wastewater treatment agent dosing device for hexafluoroethanepropanol production as described in claim 9, characterized in that: Includes the following steps: Step 1: When the sewage enters the sewage tank, first install the medicine box (1) on the sewage tank, and then have the staff add the medicine into the medicine box (1); Step 2: Then start the motor on the back of the medicine box (1) manually. The motor will drive the reciprocating screw (4) to rotate. The reciprocating screw (4) will drive the sliding groove (13) to rotate. The sliding groove (13) will rotate and contact the medicine box (8) through the inner wall, thereby driving the medicine box (8) to rotate. Step 3: The medicine box (8) rotates because the inner wall contacts the circumferential surface of the reciprocating screw 2 (7). The reciprocating screw 2 (7) rotates through the limiting part of the fixed block (3). At this time, the reciprocating sliding groove of the circumferential surface of the reciprocating screw 2 (7) contacts the medicine box (8), thereby driving the medicine box (8) to move back and forth. Step 4: The box opening (10) moves back and forth to contact the inlet (9), so that the box opening (10) and the inlet (9) overlap, allowing the medicine to enter the inner wall of the medicine box (8). After the medicine enters the medicine box (8), it continues to move, thereby separating from the external medicine. Finally, the medicine inside the medicine box (8) is sprayed.
