Description

Technical Field

[0001] The present invention relates to the field of sewage treatment devices, and in particular to a sewage treatment device with a pH adjustment function. Background Art

[0002] In sewage treatment, adjusting the pH of sewage is an essential step, because when the pH value of water is too high or too low, it will lead to problems such as decreased sewage treatment capacity, poor treatment effect, and environmental pollution. Therefore, in the sewage treatment process, the pH value of sewage must be adjusted to an appropriate range. For example, the Chinese utility model patent with the public document number: CN220788231U discloses a tower-type sewage treatment device with a pH value self-adjusting function. The utility model detects the pH value of sewage by a pH monitor, and according to the detection result, the acid solution solenoid valve and the alkaline solution solenoid valve are opened, so that the solution is sprayed into the tower body through the nozzle by the feed pump, and merged with the sewage in the tower body to achieve a neutralization reaction and complete the automatic adjustment of the pH value. The scheme is novel in structure, can realize automatic adjustment, and has high practicality;

[0003] However, sewage contains a large amount of solid waste, and some of these solid wastes can change the pH value of sewage after being dissolved in water. At the same time, the inner wall of the treatment box contains a large amount of adhered dirt. After these dirts fall into the sewage and dissolve, they may also change the pH value of the sewage. The utility model only adds a regulating liquid into the sewage to perform a neutralization reaction to change the pH value. However, when the sewage begins to stand and react, the pH value of the sewage may change after the solid waste in the sewage is dissolved, affecting the subsequent sewage treatment process.

[0034] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a vibrating liquid removal assembly 8 is movably installed at the upper position of the processing box 1, and the vibrating liquid removal assembly 8 includes a collecting box 804, an eccentric wheel 806 and a second transmission gear 809.

The scraping and unblocking component 9 also includes bristles 909 and a filter plate 911. The bristles 909 are fixedly connected to the brush plate 908, and the filter plate 911 is fixedly connected to the drain pipe 4. The bristles 909 are located on the side of the filter plate 911. The rectangular scraper 901 slides on the inner wall of the processing box 1 to scrape off the dirt on the inner wall. The threaded connection between the dispersion screw 701 and the screw tube 903 provides the power for the rectangular scraper 901 to move up and down. As the rectangular scraper 901 moves downward, the dirt on the rectangular scraper 901 is easy to soak Soaking in sewage, cooperating with the forward and reverse stirring of sewage, the dirt is dispersed into the sewage, so that the subsequent PH detection value is more accurate. A buffer rubber ring 905 is set on the support table 904 to prevent the support table 904 from directly hitting the No. 1 transmission gear 703. The buffer rubber ring 905 is used to buffer the collision. The brush plate 908 and the bristles 909 repeatedly brush the filter plate 911, so that the filter plate 911 is easy to dredge and not easy to be blocked. It is more convenient for subsequent sewage discharge. When the dosing port 5 is added with drugs such as flocculants and the sewage is left to stand, the dirt is settled in the lower position, and the upper layer of clean water is discharged through the drain pipe 4, and the sewage pump 11 discharges the dirt in the lower layer.

[0036] It should be noted that the present invention is a sewage treatment device with a pH adjustment function. The sewage enters the treatment box 1 through the collection box 804. The leakage hole of the collection box 804 separates the solid garbage and the liquid sewage. The pH detector 601 in the treatment box 1 detects the sewage and feeds the information back to the PLC controller 602. The PLC controller 602 opens the corresponding solenoid valve No. 1 608 or the solenoid valve No. 2 610 according to the information, introduces the acid or alkali solution into the suction pipe 606, and sends it into the treatment box 1 through the water pump 604 and the liquid adding pipe 605. The PLC controller 602 synchronously starts the stepper motor 704, so that the dispersion screw 701 rotates under the drive of the stepper motor 704, and the dispersion screw The dispersion blades 705 on 701 stir the sewage, so that the acid-base regulating liquid and the sewage are mixed more quickly and fully. The dispersion screw 701 is driven by the mutual meshing of the No. 1 transmission gear 703 and the No. 2 transmission gear 809, so that the vibration rod 805 rotates, and the eccentric wheel 806 on the vibration rod 805 rotates synchronously. The eccentric wheel 806 vibrates the collection box 804 at the upper position, so that the collection box 804 moves and vibrates on the No. 1 spring 802 of the movable rod 801. By vibrating the collection box 804, the liquid contained in the solid garbage therein is quickly shaken down to the treatment box 1 through the liquid hole 810, and quickly mixed with the sewage in the treatment box 1. The stepper motor 704 rotates forward and reverse alternately, and the rectangular scraper 901 fits the rectangular structure of the treatment box 1, so that the rectangular scraper 901 can only move up and down along the dispersion screw 701. When the dispersion screw 701 rotates, the screw tube 903 moves upward, and the rectangular scraper 901 is driven to move by the support rod 902, so that the rectangular scraper 901 scrapes against the inner wall of the treatment box 1, so that the adhered dirt on the treatment box 1 is scraped off. As the dispersion screw 701 rotates in the opposite direction, the rectangular scraper 901 moves downward and enters the sewage, so that the dirt on the rectangular scraper 901 is easy to soak in the sewage. The dispersion screw 701 drives the dispersion leaves 705 to rotate, so that the dispersion leaves 705 stir the sewage, thereby dispersing and dissolving the dirt. During the process, the brush plate 908 on the vertical plate 906 moves synchronously, and the brush plate 908 is pushed sideways by the second spring 910, so that the brush plate 908 and the bristles 909 are squeezed sideways, and the filter plate 911 is brushed and unblocked, so that the liquid in the drain pipe 4 and the treatment box 1 can be connected to each other more smoothly, and the acid-base regulating liquid is easy to diffuse into the drain pipe 4. When the sewage is discharged in the later stage, the drain pipe 4 is not easy to be blocked. The soluble solid garbage is removed by the vibration liquid removal component 8 and the scraping and unblocking component 9, and the dirt on the inner wall of the treatment box 1 is dissolved in the sewage, thereby removing the factors that interfere with the pH value, so that when the sewage is tested for pH again in the future, the pH detection result is more accurate, and the pH value is not easy to change when the sewage is left stationary for a long time.
