Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a dosing port structure of a sewage treatment dosing tank. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. When treating sewage, it is often necessary to use a medicine tank to prepare chemicals, and add the prepared chemicals to the sewage to kill bacteria, viruses and other pathogenic microorganisms in the sewage, so as to further purify the water quality.

[0003] As mentioned in our country's public patent, a sewage treatment agent dosing device with application number CN220664948U is mentioned: "A dosing tank, a stirring mechanism is arranged at the top and inside of the dosing tank, a dosing port is installed at the top of the dosing tank on one side of the stirring mechanism, a water outlet is arranged at the bottom end of the outer wall of the dosing port, and a collector is installed at the opening of the dosing port, the top of the collector has a circular opening, and the bottom of the collector has a square opening; fixed plates are arranged on both sides of the square opening at the bottom of the collector, and a driving mechanism extending to the bottom opening of the collector is arranged on the fixed plate. The utility model can crush and crush the added flocculant by arranging a driving mechanism and a cleaning component, so that the agglomerated flocculant is crushed, and the cleaning component can clean the flocculant attached to the rolling roller to prevent the flocculant from sticking to the rolling roller."

[0004] In the utility model retrieved above, the agglomerated medicine is crushed by a rolling roller, and the crushed medicine enters the tube through the medicine outlet to mix with the liquid in the tank. Although this method can mix the medicine and water, we found that this method still has certain defects in specific simulation use:

[0005] As is known to all, due to the presence of water inside the tank, when the moisture in the water rises, it will enter the medicine dispensing port, causing the inner wall of the medicine dispensing port to become wet. When the medicine passes through the medicine dispensing port, the medicine may adhere to the inner wall of the medicine dispensing port, or even condense on the inner wall of the medicine dispensing port, causing blockage, resulting in a smaller aperture of the medicine dispensing port, affecting the normal medicine dropping efficiency. In addition, the medicine naturally enters the tank from the medicine dispensing port from top to bottom. When there are many broken medicines, the medicine dispensing port often does not have time to quickly export the medicine, which will cause the medicine to fall untimely, or even accumulate in the medicine adding port, affecting the mixing efficiency of the medicine and the water in the tank. Therefore, in view of the defects of the prior art such as those mentioned above, we have specifically designed a medicine adding port structure for a sewage treatment medicine adding tank with faster dosing efficiency and avoiding pipe blockage.

Sliding at the pipe 203 is beneficial for the medicine to enter the medicine outlet pipe 203. A grinding motor 3 is also installed on the top of the grinding pipe 201. The power output shaft of the grinding motor 3 movably penetrates into the interior of the grinding pipe 201 and is installed with a grinding roller 8; a cleaning component is arranged inside the medicine outlet pipe 203, and the cleaning component includes a rotating rod 9, a scraper 12, a scraper 2 13 and a guide cover 14. The rotating rod 9 is rotatably connected to the interior of the medicine outlet pipe 203 and is transmission-connected to the stirring rod 10. Two scrapers 12 are arranged and one end of each scraper 12 is fixed on the rod body of the rotating rod 9. One side of the scraper 12 slides and fits on the guide slope 202, and the scraper 12 can move the medicine remaining on the guide slope 202.

[0026] In this embodiment, a gap is left between the surface of the grinding roller 8 and the inner wall of the grinding pipe 201 . The inner wall of the grinding pipe 201 is designed to be a frosted structure. The side of the grinding pipe 201 is connected to a drug feeding pipe 4 for adding materials to the inside of the grinding pipe 201 .

[0027] Specifically, through the designed grinding roller 8 and grinding pipe 201, the grinding roller 8 can be used to grind the blocky medicine, which is more conducive to the subsequent mixing with water. The medicine feeding pipe 4 is set on the grinding pipe 201, which can facilitate the continuous addition of medicine into the grinding pipe 201 to ensure the continuous addition of medicine.

[0028] In this embodiment, three scraper blades 13 are fixed equidistantly on the surface of the rotating rod 9, and the scraper blade 13 slides on the inner wall of the medicine outlet pipe 203 away from the rotating rod 9. A limiting block 1301 is fixed in the middle of each scraper blade 13, and the limiting block 1301 is slidably connected to the limiting groove opened on the inner wall of the medicine outlet pipe 203.

[0029] Specifically, the scraper blade 13 can scrape the medicine on the inner wall of the medicine outlet pipe 203, so as to prevent the medicine from adhering to the inner wall of the medicine outlet pipe 203 and condensing. A limit block 1301 is set on the scraper blade 13, which cooperates with the limit groove on the inner wall of the medicine outlet pipe 203 to improve the stability of the entire rotating rod 9, scraper blade 1 12 and scraper blade 2 13 during movement.

[0030] In this embodiment, the guide cover 14 is fixed on the rod body of the rotating rod 9 and is located at the bottom of the second scraper blade 13. The guide cover 14 is designed to be an inclined structure.

[0031] Specifically, the guide cover 14 can have a certain shielding effect on the I-wheel 15, and on the other hand can guide the flow of the medicine, so that the medicine can be better dispersed and fall into the dosing tank body 1, which is more conducive to mixing with the water.

[0032] In this embodiment, an I-shaped wheel 15 is fixed to the bottom of the rod body of the rotating rod 9 , and an I-shaped wheel 15 is also fixed to the rod body of the stirring rod 10 . The two I-shaped wheels 15 are connected by a transmission belt 16 .

[0033] Specifically, by providing the I-wheel 15 and the transmission belt 16, the stirring rod 10 can synchronously drive the rotating rod 9 to rotate when rotating, thereby facilitating the formation of a toggle structure in the dosing component 2 to avoid blockage of the medicine.

[0034] In this embodiment, the other side of the top of the dosing tank body 1 is connected to a liquid injection port 6 , and the bottom of the front side of the dosing tank body 1 is connected to a liquid discharge port 7 .

[0035] Specifically, the designed liquid injection port 6 can facilitate the addition of water into the dosing tank body 1, while the designed liquid discharge port 7 facilitates the subsequent discharge of the mixed water inside the dosing tank body 1, so as to facilitate the subsequent discharge for sewage treatment.

[0036] When using:

[0037] The staff can guide the water liquid from the liquid injection port 6 to the dosing tank body 1, start the servo motor 5, the power output shaft of the servo motor 5 drives the stirring rod 10 to rotate, and the stirring rod 10 drives the stirring blade 11 to stir the water liquid inside the dosing tank body 1 when rotating, and then put the medicine into the medicine feeding pipe 4, and start the grinding motor 3, the power output shaft of the grinding motor 3 drives the grinding roller 8 to rotate, and grinds the medicine entering the grinding pipe 201;

[0038] Since the stirring rod 10 rotates at a constant speed, the stirring rod 10 can synchronously drive the rotating rod 9 to rotate through the I-shaped wheel 15 and the transmission belt 16 when rotating. When the rotating rod 9 rotates, it can synchronously drive the scraper 12 to move on the surface of the guide slope 202, and drive the scraper 2 13 to scrape the inner wall of the medicine outlet pipe 203, so that the scraper 12 is used to move the medicine at the bottom of the grinding pipe 201, so that it can enter the medicine outlet pipe 203 more efficiently, and the scraper The second 13 can scrape off the medicine adhered to the inner wall of the medicine outlet pipe 203, so as to prevent the medicine from condensing on the inner wall of the medicine outlet pipe 203 and clogging the medicine outlet pipe 203. When the medicine falls from the bottom of the medicine outlet pipe 203, it will first pass through the blocking of the guide cover 14, which can prevent the medicine from falling directly on the I-shaped wheel 15, and can also use the slope of the guide cover 14 to guide the medicine into the inside of the medicine adding tank body 1 and mix with the water inside the medicine adding tank body 1.

[0039] After being ground, the medicine can be better mixed with the water inside the medicine adding tank body 1, and then the mixed medicine can be discharged through the drain port 7 for subsequent sewage treatment.
