Description

Technical Field

[0001] The utility model relates to the technical field of medical-grade carboxyl nitrile latex, in particular to a wastewater treatment device for producing medical-grade carboxyl nitrile latex. Background Art

[0002] Medical-grade carboxyl nitrile latex is a polymer material widely used in the medical field. It is based on anionic polymer emulsion technology and is produced through a specific chemical synthesis method. The wastewater generated during the production of medical-grade carboxyl nitrile latex usually contains a large amount of organic compounds and suspended matter. These substances mainly come from the raw materials, reactants, catalysts, and washing and separation processes in the production process. If this type of wastewater is discharged directly without treatment, it will cause serious pollution to the environment; the wastewater generated during the production of nitrile latex contains emulsion suspended matter, which will seriously affect the water quality and the environment. In order to solve this problem, the use of demulsifiers can be introduced. Demulsifiers are chemical substances that can cause emulsion suspended matter in wastewater to aggregate into larger particles, facilitating subsequent solid-liquid separation treatment; solid particles, grease and other pollutants in wastewater are removed by precipitation, filtration, centrifugation and other methods. The specific sewage treatment method should be determined according to the nature of the sewage, treatment requirements and local environmental protection regulations. At the same time, in order to protect the environment, the generation and discharge of sewage should be reduced as much as possible to improve resource utilization efficiency;

[0003] Referring to the Chinese patent authorization announcement number CN215137279U, the authorization announcement date is December 14, 2021, which discloses a sewage treatment device for chemical production.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0031] This embodiment is a medical-grade carboxyl nitrile latex production wastewater treatment device.

[0032] like Figure 1 、 Figure 4 and Figure 5 As shown, a feed port 2 is provided on the upper side of the processing box 1, a cover is provided on the upper side of the feed port 2, a discharge port 3 is provided at the lower right side of the processing box 1, a valve is provided inside the discharge port 3, the front side of the processing box 1 is rotatably connected to the box door 4, a first motor 5 is fixedly installed on the upper side of the processing box 1, the output shaft of the first motor 5 is fixedly connected to the screw rod 6, the screw rod 6 is threadedly connected to the cleaning ring 7, the outer side of the cleaning ring 7 is tightly fitted with the inner side of the processing box 1, the cleaning ring 7 is slidably connected to the limit rod 8, the limit rod 8 is fixedly installed on the upper inner side of the processing box 1, the lower side of the limit rod 8 is fixedly connected to the limit block 9, and a partition plate 10 is provided inside the processing box 1, which divides the interior of the processing box 1 into two parts, upper and lower parts, so as to achieve the purpose of separate processing.

[0033] like Figure 3 As shown, a transfer tube 11 is provided on the rear side of the processing box 1. The transfer tube 11 is threadedly connected to the threaded rod 12. The front side of the threaded rod 12 is rotatably connected to a push ring 13. A rubber pad 14 is provided on the outside of the push ring 13. The rubber pad 14 fits tightly with the inner side of the transfer tube 11.

[0034] like Figure 2 、 Figure 4 and Figure 5As shown, a second motor 15 is provided on the lower side of the processing box 1, and the output shaft of the second motor 15 is fixedly connected to the connecting shaft 16. A stirring blade 17 is fixedly connected to the outer side of the connecting shaft 16. The stirring blade 17 is symmetrical about the vertical center axis of the connecting shaft 16. The connecting shaft 16 passes through the dividing plate 10. A cleaning blade 18 is provided above the outer side of the connecting shaft 16. The cleaning blades 18 are distributed in an array. The outer side of the cleaning blade 18 is tightly fitted with the inner side of the processing box 1, and the lower side of the cleaning blade 18 is tightly fitted with the upper side of the dividing plate 10. Specific embodiment 2

[0036] This embodiment is intended to solve the problem of emulsion suspension adhering to the inner wall of the treatment box 1 .

[0037] like Figure 4 As shown, open the cover on the upper side of the feed port 2, add the sewage generated during the production of medical-grade carboxyl nitrile latex from the feed port 2, and then add a demulsifier to the inside of the treatment box 1. The demulsifier can cause the emulsion suspension in the wastewater to aggregate into larger particles, which is convenient for subsequent solid-liquid separation treatment. Some particles in the sewage will settle to the upper side of the dividing plate 10, some will be adsorbed on the inner wall of the treatment box 1, and some will remain in the sewage because no reaction occurs. The demulsifier and emulsion suspension are still in the sewage.

[0038] like Figure 1 、 Figure 2 and Figure 4 As shown, when the first motor 5 is started, the first motor 5 will rotate with the screw rod 6. Since the screw rod 6 is threadedly connected to the cleaning ring 7, the cleaning ring 7 is limited by the limiting rod 8. The rotating screw rod 6 will move the cleaning ring 7 up and down inside the treatment box 1. Because the outer side of the cleaning ring 7 is tightly fitted with the inner wall of the treatment box 1, the cleaning ring 7 will clean up the emulsion suspension stuck to the inner wall of the treatment box 1 and drop it on the upper side of the dividing plate 10. In addition, the limiting block 9 on the lower side of the limiting rod 8 limits the cleaning ring 7 to prevent the cleaning ring 7 from moving down too much, causing the cleaning ring 7 to contact the cleaning blade 18. Specific embodiment three

[0040] This embodiment is intended to solve the problem of inconvenience in treating sewage.

[0041] like Figure 3As shown, after the sewage is added to the interior of the treatment box 1 and stands for a period of time, the threaded rod 12 is rotated, and the threaded rod 12 will move backward inside the transfer pipe 11 with the push ring 13. After the threaded rod 12 moves backward for a distance, the sewage on the upper side of the dividing plate 10 will flow from the transfer pipe 11 to the bottom of the interior of the treatment box 1, and the grease in the sewage will be adsorbed on the inner side of the treatment box 1. When the sewage has finished flowing, the threaded rod 12 is rotated in the opposite direction, and the threaded rod 12 will push the push ring 13 forward, so that the push ring 13 blocks the transfer pipe 11, and the rubber pad 14 on the outside of the push ring 13 acts as a seal.

[0042] like Figure 4 As shown, open the door 4 on the front side of the treatment box 1 and start the second motor 15. The second motor 15 will rotate inside the treatment box 1 with the cleaning blades 18 through the connecting shaft 16. The rotating cleaning blades 18 will sweep the sludge from the upper side of the dividing plate 10 to the inner side of the treatment box 1, and then discharge it from the door 4. After the sludge is cleaned, close the door 4.

[0043] like Figure 4 and Figure 5 As shown, start the second motor 15, the second motor 15 will rotate with the connecting shaft 16, and the connecting shaft 16 will rotate with the stirring blade 17, thereby accelerating the demulsifier and the emulsion suspension in the sewage to aggregate into larger particles for easy treatment. When the treatment is completed, open the valve in the discharge port 3 and discharge the sewage from the inside of the treatment box 1 to reduce the adsorption of grease in the sewage on the inner wall of the treatment box 1.
