Description

Technical Field

[0001] This invention relates to the field of wastewater treatment devices, and in particular to a dyeing and printing wastewater treatment device. Background Technology

[0002] This is called dyeing and finishing. It is a processing method, and also a general term for pretreatment, dyeing, printing, finishing, washing, etc. As early as the Neolithic Age, six or seven thousand years ago, our ancestors were able to dye linen red with hematite powder. The primitive tribes living in the Nuomuhong area of ​​the Qaidam Basin in Qinghai Province can dye wool yarn in colors such as yellow, red, brown, and blue, and weave woolen cloth with colored stripes.

[0003] Dyeing and printing wastewater refers to the wastewater discharged from dyeing and printing plants, wool dyeing and finishing plants, and silk factories that process cotton, linen, chemical fibers and their blended products, as well as silk. The volume and quality of dyeing and printing wastewater vary depending on the type of fiber and processing technology. Dyeing and printing plants typically produce large volumes of wastewater, characterized by high levels of organic pollutants, high alkalinity, and significant variations in water quality. It is considered one of the most difficult types of industrial wastewater to treat and contains dyes, sizing agents, auxiliaries, oils, acids, alkalis, fiber impurities, sand, and inorganic salts.

[0004] Wastewater from dyeing and printing is typically collected in collection tanks and then discharged into treatment ponds via discharge pipes. However, the initial treatment of this wastewater requires the separation of larger solid substances to facilitate subsequent treatment steps. Currently, the wastewater is usually directly introduced into the treatment pond, and solid substances are also added, increasing the need for subsequent removal of larger solid substances. Therefore, a wastewater treatment device is needed to filter the wastewater entering the treatment pond, allowing the larger solid substances to be separated. Summary of the Invention

[0005] The purpose of this invention is to overcome the defect that the solid matter in the wastewater cannot be separated in advance, which leads to the need for additional steps to clean the solid matter in the treatment tank, and to provide a dyeing and printing wastewater treatment device.

[0006] The technical solution to achieve the above objective is: a dyeing and printing wastewater treatment device, including a treatment tank, a discharge pipe at the bottom of the treatment tank, an inlet pipe connected to the side wall of the treatment tank, a guide mechanism connected to the port of the inlet pipe, a collection mechanism installed at the lower end of the guide mechanism, an adjustment mechanism installed on the guide mechanism, a scraping mechanism installed on the adjustment mechanism, and a limit mechanism installed on the adjustment mechanism.

[0007] Preferably, the guiding mechanism includes a guiding pipe and a filter plate, the port of the water inlet pipe is connected to the guiding pipe, the end of the guiding pipe away from the water inlet pipe is set as an opening, and the bottom end of the side wall of the guiding pipe is connected to the filter plate.

[0008] Preferably, the filter plate is arc-shaped, and the side wall end of the guide tube is provided with an installation hole. The side wall of the installation hole is connected to the filter plate, and the guide tube is located inside the treatment box.

[0009] Preferably, the collection mechanism includes an output pipe, a collection box, a box door, and an electric valve. The bottom end of the side wall of the filter plate is connected to the output pipe, the top end of the output pipe is connected to the electric valve, the bottom end of the output pipe is connected to the collection box, the side wall of the collection box is rotatably connected to the box door, the side wall of the output pipe penetrates the side wall of the processing box, and the output pipe is placed at an angle downwards.

[0010] Preferably, the adjusting mechanism includes a cover plate, connecting rods, side plates, a circular hole, a push rod motor, and a baffle. The outer sidewall of the cover plate is connected to the push rod motor, the output end of the push rod motor passes through the cover plate, and the output end of the push rod motor is connected to the baffle. The inner sidewall of the cover plate is connected to two symmetrically distributed connecting rods, one end of which is connected to the side plate. The sidewall of the side plate has a circular hole, which is aligned with the baffle and the water inlet pipe. The sidewall of the side plate away from the connecting rods is in contact with the inner sidewall of the guide pipe.

[0011] Preferably, the sidewalls of the cover plate and the guide pipe are each provided with three insertion holes. One end of the water inlet pipe passes through the sidewall of the guide pipe. The top end of the guide pipe is connected to a round pipe. The bottom end of the round pipe is connected to the inside of the guide pipe. The top end of the round pipe is provided with a cap. The sidewall of the cover plate is in contact with the sidewall of the open end of the guide pipe. The insertion holes on the cover plate are aligned with the insertion holes on the guide pipe.

[0012] Preferably, the scraping mechanism includes a rotary motor, a drive gear, a gear ring, a scraper, and a cut. The rotary motor is connected to the side wall of the cover plate, and the output end of the rotary motor is connected to the drive gear. The side wall of the drive gear meshes with the gear ring, and the side wall of the gear ring is rotatably connected to the side plate. The scraper is connected to the side wall of the gear ring, and the scraper has a cut in its side wall, the cut being triangular in shape.

[0013] Preferably, the limiting mechanism includes a fixed block, a round rod, a screw, a pressure block, and an insertion rod. The fixed block has a round rod connected to its side wall, the round rod has a pressure block slidably connected to its side wall, the pressure block has a screw threadedly connected to its side wall, and the pressure block has an insertion rod connected to its side wall. The insertion rod is inserted into an insertion hole.

[0014] The beneficial effects of this invention are:

[0015] 1) Fix the guide pipe at the end of the inlet pipe, so that the inlet pipe and the guide pipe are integrated. Let the sewage flow from the inlet pipe into the guide pipe. Use the limiting mechanism to fix the adjusting mechanism on the guide pipe to seal the opening of the guide pipe. This will allow the sewage to flow out only from the filter plate located below, thereby filtering out the impurities in the sewage and preventing the impurities from flowing into the treatment tank.

[0016] 2) After the adjustment mechanism is fixed on the guide pipe by the limiting mechanism, and the filter plate is blocked, the push rod motor is started. The push rod motor drives the baffle to push towards the round hole, so that the baffle blocks the round hole. Since the round hole is connected to the inlet pipe, the sewage in the inlet pipe cannot flow into the guide pipe. At this time, the scraping mechanism is started to scrape off the impurities on the filter plate and push them into the collection mechanism to complete the scraping and collection of impurities. Then, the baffle is pulled back so that the round hole is no longer blocked, and the dyeing sewage can flow normally into the guide pipe.

[0017] 3) Start the rotary motor and open the electric valve to make the drive gear rotate, which in turn drives the gear ring to rotate. The gear ring then drives the scraper to rotate, and the scraper scrapes off the impurities attached to the filter plate. The triangular cut allows the impurities to gather inside the cut and be pushed into the top of the output pipe by the scraper. The impurities will carry some dyeing wastewater and slide down the top of the output pipe into the collection box, thus completing the effect of scraping and collecting the impurities. Open the box door to clean the impurities in the collection box. Attached Figure Description

[0034] The guide pipe 301 is fixed at the end of the inlet pipe 2, so that the inlet pipe 2 and the guide pipe 301 are integrated, allowing sewage to flow from the inlet pipe 2 into the guide pipe 301. The adjusting mechanism 5 is fixed on the guide pipe 301 by the limiting mechanism 7, so that the opening of the guide pipe 301 is sealed, and the sewage can only flow out from the filter plate 302 located below, thereby filtering out the impurities in the sewage and preventing the impurities from flowing into the treatment tank 1.

[0035] Reference Appendix Figure 3-10 The limiting mechanism 7 includes a fixed block 701, a round rod 702, a screw 703, a pressure block 704, and an insertion rod 705. The round rod 702 is connected to the side wall of the fixed block 701, the pressure block 704 is slidably connected to the side wall of the round rod 702, the screw 703 is threadedly connected to the side wall of the pressure block 704, and the insertion rod 705 is connected to the side wall of the pressure block 704. The insertion rod 705 is inserted into the insertion hole 8.

[0036] Align and attach the cover plate 501 with the opening of the guide tube 301, align the insertion hole 8, and ensure that the side plate 503 is tightly against the inner side wall of the guide tube 301. Insert the insertion rod 705 into the insertion hole 8 and attach the pressure block 704 to the outer side wall of the cover plate 501, so that the fixing block 701 is located on the side wall of the guide tube 301 near the water inlet pipe 2. Rotate the screw 703, which will drive the fixing block 701 to move closer to the guide tube 301, so that the fixing block 701 and the pressure block 704 will press the cover plate 501 and the guide tube 301 respectively, thereby fixing the cover plate 501 on the guide tube 301 and sealing the opening of the guide tube 301.

[0037] Reference Appendix Figure 4-10The adjusting mechanism 5 includes a cover plate 501, connecting rods 502, side plates 503, a circular hole 504, a push rod motor 505, and a baffle 506.

One end of each connecting rod 502 is connected to the side plate 503. A circular hole 504 is provided on the sidewall of the side plate 503, and the circular hole 504 is aligned with the baffle 506. The water inlet pipe 2 is aligned, and the side wall of the side plate 503 away from the connecting rod 502 is attached to the inner side wall of the guide pipe 301. The side wall of the cover plate 501 and the side wall of the guide pipe 301 are both provided with three insertion holes 8. One end of the water inlet pipe 2 passes through the side wall of the guide pipe 301. The top end of the guide pipe 301 is connected to a round pipe 9. The bottom end of the round pipe 9 is connected to the inner side of the guide pipe 301. The top end of the round pipe 9 is provided with a cap. The side wall of the cover plate 501 is attached to the side wall of the open end of the guide pipe 301. The insertion hole 8 on the cover plate 501 is aligned with the insertion hole 8 on the guide pipe 301.

[0038] After the adjustment mechanism 5 is fixed to the guide pipe 301 by the limiting mechanism 7, and the filter plate 302 is blocked, the push rod motor 505 is started. The push rod motor 505 drives the baffle 506 to push towards the round hole 504, so that the baffle 506 blocks the round hole 504. Since the round hole 504 is connected to the water inlet pipe 2, the sewage in the water inlet pipe 2 cannot flow into the guide pipe 301. At this time, the scraping mechanism 6 is started to scrape off the impurities on the filter plate 302 and push them into the collection mechanism 4 to complete the scraping and collection of impurities.

The side wall of the gear ring 603 is connected to the scraper 604. The side wall of the scraper 604 has a cut 605, which is triangular in shape.

[0040] Start the rotary motor 601 and open the electric valve 404 to make the drive gear 602 rotate, which in turn drives the gear ring 603 to rotate. The gear ring 603 drives the scraper 604 to rotate, and the scraper 604 scrapes off the impurities attached to the filter plate 302. The triangular cut 605 allows the impurities to gather inside the cut 605 and be pushed into the top of the output pipe 401 by the scraper 604. The impurities will carry some dyeing wastewater and slide down the top of the output pipe 401 into the collection box 402, thus completing the effect of scraping and collecting the impurities.
