Description

Technical Field

[0001] The present invention relates to the technical field of water-based paints, and more specifically, to a sewage treatment device used in the production and processing of water-based paints. Background Art

[0002] Water-based paint refers to paint that uses water as the main solvent or dispersion medium. Compared with traditional solvent-based paint, water-based paint has the advantages of environmental protection, low VOC (volatile organic compound) emissions, non-flammability, and low odor. During the production process, the use of water-based paint reduces pollution to the environment and improves production safety. Due to its environmental protection characteristics, water-based paint has been promoted and applied in many countries and regions, especially in fields with high environmental protection requirements.

[0003] According to the patent document: CN114602218A, a water-based paint wastewater treatment equipment disclosed includes: a sewage collection component, a plurality of sewage collection components that can collect splashed sewage are fixedly installed around the four longitudinal side outer surfaces of the grit chamber, and the sewage collection component includes: an upper shell, a lower shell, a sewage guide component that can guide sewage collection and prevent overflow, and a sewage suction component that can absorb sewage; a plurality of upper shells are fixedly installed around the four longitudinal side outer surfaces of the grit chamber; a lower shell is fixedly installed on the outer surface of the bottom side of the left and right ends of the upper shell; a sewage guide component is movably installed between the upper and middle ends of the upper shell; a sewage suction component is movably installed between the lower right end of the upper shell and the right end of the lower shell. This water-based paint wastewater treatment equipment can make the outside of the grit chamber have a sewage collection function. When the water-based paint wastewater is injected into the grit chamber, even if splashing occurs accidentally, the sewage in the grit chamber will not overflow everywhere, thereby ensuring the cleanliness of the sewage treatment working environment.

[0004] Amino resin is used in the production of water-based paint. After the production is completed, the amino resin wastewater generated is usually treated by sewage treatment equipment to meet the emission standards. However, most of the treatment methods for amino resin wastewater are to add lime to the amino resin water and carry out neutralization reaction in the reaction tank to convert the nitrogen element in the amino resin into a water-insoluble precipitate, thereby meeting the emission standards. However, the capacity of the general reaction tank is limited. After adding wastewater to the reaction tank, if lime is added directly, the pressure in the reaction tank may increase sharply, and there is a risk of wastewater overflow. In addition, the amount of lime added needs to be precisely controlled, otherwise it may result in incomplete treatment or excessive lime residue, affecting the subsequent treatment effect. Summary of the invention

The bottom ends of the two screw rods 218 extend to the inner walls of the two transmission grooves 212 opened on the front side of the vertical plate 211 respectively and are rotatably connected to the bottom of the inner wall of the transmission groove 212. The bottom front side of the dual-axis motor placement block 219 is rotatably connected with a rotating rod 2110. The inner wall ring array of the rotating rod 2110 is provided with a slide groove. The outer wall of the rotating rod 2110 is provided with a thread. The outer wall of the rotating rod 2110 is threadedly connected with a high-position monitoring block 2111. The rear side of the outer wall of the high-level monitoring block 2111 is rotatably connected to the inner wall of the middle slide groove 214 opened in the middle part of the front side of the vertical plate 211, and the front side of the inner wall of the high-level monitoring block 2111 is fixedly connected with the outer slide bar 2112. The low water level monitoring mechanism 22 includes a transmission plate 221, and the left and right sides of the rear side of the transmission plate 221 are respectively fixedly connected with transmission blocks 222. The outer walls of the two transmission blocks 222 are respectively slidably connected to the inner walls of the two transmission grooves 212 opened on the front side of the vertical plate 211. The inner walls of the two transmission blocks 222 are respectively threadedly connected to the outer walls of the two screw rods 218. The top of the transmission plate 221 is fixedly connected with a motor 226. The output end of the machine 226 is fixedly connected with a control rod 227, and the outer wall of the control rod 227 is fixedly connected with a control rod slide 228 in a circular array. The outer wall of the control rod 227 is slidably connected to the inner wall of the rotating rod 2110, and the outer walls of multiple control rod slides 228 are respectively slidably connected to the inner walls of multiple slide grooves opened on the inner wall of the rotating rod 2110. The front side of the transmission plate 221 is fixedly connected with a slide connecting shaft 223, and the inner wall of the slide connecting shaft 223 is fixedly connected with a slide 224. The top of the outer wall of the slide 224 is slidably connected to the inner wall of the outer slide 2112, and the bottom end of the slide 224 is fixedly connected with a low-position monitoring block 225;

[0036] When wastewater is input into the inner wall of the intermittent reaction tank 1 and lime needs to be added, first, the dual-axis motor 215 is started. After the dual-axis motor 215 is started, the conical teeth 216 at both ends of the transmission rotate, and the two conical teeth 216 rotate to engage the two second conical teeth 217 to drive the bottom screw rod 218 to rotate. After the two screw rods 218 rotate, the transmission block 222 moves downward on the inner wall of the transmission groove 212 through the texture axial direction of the screw rod 218, and the two transmission blocks 222 move downward so as to The transmission plate 221 and the front sliding rod connecting shaft 223 and the sliding rod 224 and the low-position monitoring block 225 on the inner wall of the sliding rod connecting shaft 223 are driven to move downward. When the sliding rod 224 moves downward, it slides downward on the inner wall of the outer sliding rod 2112 to ensure that the sliding rod 224 and the low-position monitoring block 225 will not tilt. After the low-position monitoring block 225 moves downward until the inner wall of the intermittent reaction tank 1 contacts the sewage surface, the dual-axis motor 215 stops working and the low-position monitoring block 225 stays on the sewage surface.

[0037] Since the motor 226 is fixed on the top of the transmission plate 221, when the transmission plate 221 moves downward, the motor 226 drives the control rod 227 at its top to move downward, and the control rod 227 slides on the inner wall of the rotating rod 2110 through the control rod slide 228. When the low-level monitoring block 225 stays on the sewage surface, the motor 226 is started at this time. The motor 226 starts to drive the rotating rod 2110 to rotate through the rotation of the control rod 227. The rotating rod 2110 rotates, thereby driving the high-level monitoring block 2111 to move downward axially through the threaded axis opened on the outer wall of the rotating rod 2110. When the high-level monitoring block 2111 contacts the highest surface of the intermittent reaction tank 1, the motor 226 stops working. At this time, the working Personnel can know the remaining capacity of the intermittent reaction tank 1 through the positions of the low-level monitoring block 225 and the high-level monitoring block 2111. When the high-level monitoring block 2111 and the low-level monitoring block 225 reach the designated positions, the staff issues a command to transport lime to the inner wall of the intermittent reaction tank 1 through the lime conveying mechanism 3. The water level changes in the intermittent reaction tank 1 are monitored in real time through the high-level monitoring block 2111 and the low-level monitoring block 225 to ensure the accurate addition of lime. When the water level in the intermittent reaction tank 1 rises to the high-level monitoring block 2111, the high-level monitoring block 2111 sends an alarm and triggers the stop of the lime conveying mechanism 3 to prevent the pressure in the reaction tank from increasing suddenly due to excessive addition of lime, causing wastewater overflow.

[0038] like Figure 8-10As shown, the lime conveying mechanism 3 includes a lime storage box 31, the rear side of the lime storage box 31 is fixedly connected to a lime crushing bin 32, the lime storage box 31 includes a storage box body 311, the top and bottom of the storage box body 311 are respectively fixedly connected to the inner sides of the upper and lower groups of connecting plates 213, the left and right sides of the bottom of the rear side of the storage box body 311 are respectively fixedly connected to a feeding pipe 312, the inner sides of the two feeding pipes 312 are provided with a feeding pipe side groove 313, the rear side of the storage box body 311 is fixedly connected to a control board 314, and the left and right sides of the rear side of the control board 314 are respectively fixedly connected to a slide plate 315, a hydraulic push rod 316 is fixedly connected to the top of the middle part of the rear side of the control panel 314, and a push plate 317 is fixedly connected to the bottom end of the hydraulic push rod 316. Two inclined sliding grooves 318 with opposite inclinations are respectively provided on the left and right sides of the rear bottom of the push plate 317. The left and right sides of the bottom of the control panel 314 are respectively slidably connected to the expansion blocks 319, and the front sides of the two expansion blocks 319 are fixedly connected to the expansion block sliders 3110. The outer walls of the two expansion block sliders 3110 are respectively slidably connected to the bottom of the inner walls of the two inclined sliding grooves 318, and the inner sides of the two expansion blocks 319 are fixedly connected to the expansion rods 311 1. The outer bottoms of the two expansion rods 3111 are respectively fixedly connected with baffles 3112, and the outer walls of the two baffles 3112 are respectively slidably connected to the inner walls of the feeding pipe 312 through the feeding pipe side grooves 313. The lime crushing bin 32 includes a crushing bin body 321. The left and right sides of the front side of the crushing bin body 321 are respectively provided with feeding pipe through grooves 322. The inner walls of the two feeding pipe through grooves 322 are respectively fixedly connected to the rear sides of the outer walls of the two feeding pipes 312. The rear side of the crushing bin body 321 is fixedly connected with a motor connecting plate 323, and the rear side of the motor connecting plate 323 is fixedly connected with a second motor 324. The output end of the second motor 324 extends to the front side of the motor connecting plate 323, and the inner wall of the crushing bin body 321 is rotatably connected to a plurality of crushing rollers 325. The rear sides of the three crushing rollers 325 in the middle are all extended to the rear side of the outer wall of the crushing bin body 321 and are all fixedly connected to a transmission disc 326, and the rear side of one of the transmission discs 326 is fixedly connected to the output end of the second motor 324. The outer walls of the plurality of transmission discs 326 are covered with crawlers 327. A crushing bin feeding pipe 328 is fixedly connected to the bottom right side of the crushing bin body 321, and a blower 329 is fixedly connected to the rear side of the top of the crushing bin feeding pipe 328.

[0039] When lime needs to be transported, the hydraulic push rod 316 is first started. After the hydraulic push rod 316 is started, the push plate 317 is pushed downward. The push plate 317 pushes the expansion block slider 3110 to slide on the inner wall of the inclined slide groove 318 through the two inclined slide grooves 318 facing opposite directions, thereby making the two expansion blocks 319 move inward and drive the two baffles 3112 to move inward to remove the inner wall of the feeding pipe 312. With the removal of the baffles 3112, the lime particles slide into the crushing bin body 321 along the feeding pipe 312 under the action of gravity;

[0040] In order to prevent the lime from being partially attached together to form larger lime blocks due to humidity due to long-term storage, the second motor 324 is started at this time. The rotation of the motor drives the transmission disk 326 to rotate, and the multiple crushing rollers 325 are rotated together through the crawler 327. The rotation of the crushing rollers 325 can crush the larger lime blocks into smaller particles to ensure the uniformity and fluidity of the lime. Then the blower 329 is started. The operation of the blower 329 generates airflow to transport the crushed lime particles through the crushing bin feeding pipe 328 to the interior of the intermittent reaction tank 1 to mix with the sewage.

[0041] Working principle of the present invention: after wastewater is input into the inner wall of the intermittent reaction tank 1, when lime needs to be added, first, the dual-axis motor 215 is started. After the dual-axis motor 215 is started, the conical teeth 216 at both ends of the transmission rotate, and the two conical teeth 216 rotate to engage the two second conical teeth 217 to drive the bottom screw rod 218 to rotate. After the two screw rods 218 rotate, the transmission block 222 moves downward on the inner wall of the transmission groove 212 through the texture of the screw rod 218. The two transmission blocks 222 move downward to drive the transmission plate 221 and the front side slide rod connecting shaft 223 and the slide rod connecting shaft 223. The slide bar 224 on the inner wall and the low-position monitoring block 225 move downward, and when the slide bar 224 moves downward, it slides downward on the inner wall of the outer slide bar 2112 to ensure that the slide bar 224 and the low-position monitoring block 225 will not tilt. After the low-position monitoring block 225 moves downward until the inner wall of the intermittent reaction tank 1 contacts the sewage surface, the dual-axis motor 215 stops working at this time, and the low-position monitoring block 225 stays on the sewage surface. Since the motor 226 is fixed on the top of the transmission plate 221, when the transmission plate 221 moves downward, the motor 226 drives the control rod 227 at its top to move downward, and the control rod 227 controls The rod slide bar 228 slides on the inner wall of the rotating rod 2110. When the low-level monitoring block 225 stays on the sewage surface, the motor 226 is started. The motor 226 starts to rotate through the control rod 227 to drive the rotating rod 2110 to rotate. The rotating rod 2110 rotates, thereby driving the high-level monitoring block 2111 to move downward axially through the threaded axis opened on the outer wall of the rotating rod 2110. When the high-level monitoring block 2111 contacts the highest surface of the intermittent reaction tank 1, the motor 226 stops working. At this time, the staff can know the intermittent reaction tank 1 through the positions of the low-level monitoring block 225 and the high-level monitoring block 2111 1, when the high-level monitoring block 2111 and the low-level monitoring block 225 reach the designated position, the staff issues a command to transport lime to the inner wall of the intermittent reaction tank 1 through the lime transport mechanism 3, and the water level changes in the intermittent reaction tank 1 are monitored in real time by the high-level monitoring block 2111 and the low-level monitoring block 225 to ensure the accurate delivery of lime. When the water level in the intermittent reaction tank 1 rises to the high-level monitoring block 2111, the high-level monitoring block 2111 sends an alarm and triggers the stop of the lime transport mechanism 3 to prevent the pressure in the reaction tank from increasing suddenly due to excessive addition of lime, and wastewater overflow;

[0042] When it is necessary to transport lime, the hydraulic push rod 316 is first started. After the hydraulic push rod 316 is started, the push plate 317 is pushed downward. The push plate 317 pushes the expansion block slider 3110 to slide on the inner wall of the inclined slide groove 318 through the two inclined slide grooves 318 facing opposite directions, thereby making the two expansion blocks 319 move inward and drive the two baffles 3112 to move inward to remove the inner wall of the feed pipe 312. With the removal of the baffles 3112, the lime particles slide into the crushing bin body 321 along the feed pipe 312 under the action of gravity. In order to prevent the lime from being crushed due to its long Long-term storage may cause some lime to adhere together into larger lime blocks due to humidity. At this time, the second motor 324 is started, and the motor rotation drives the transmission disk 326 to rotate, and the multiple crushing rollers 325 are rotated together through the crawler 327. The rotation of the crushing rollers 325 can crush the larger lime blocks into smaller particles to ensure the uniformity and fluidity of the lime. Then the blower 329 is started, and the operation of the blower 329 generates airflow to transport the crushed lime particles through the crushing bin feeding pipe 328 to the interior of the intermittent reaction tank 1 to mix with the sewage.
