Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an automatic feeding sewage treatment pool. Background Art

[0002] A sewage treatment pool is a treatment pool used to treat wastewater produced during the factory production process. By putting the sewage treatment pool into use, the sustainable development of the enterprise can be maintained, the waste of water resources can be reduced, and production costs can be lowered.

[0003] The patent with the patent announcement number CN219950668U relates to the field of sewage treatment technology, including a treatment tank body and a feeding hopper. The upper side of the treatment tank body is provided with a feeding hopper, and the upper side of the feeding hopper is docked with a cover plate. The lower end of the feeding hopper is installed with a dust butterfly valve, and the lower side of the dust butterfly valve is fixed with a feeding pipe. The automatic feeding sewage treatment tank allows all the treatment reagents to be put into the feeding hopper when feeding the chemical sewage treatment tank. By controlling the dust butterfly valve, a small motor and a blower fan, the treatment reagents are automatically fed, making it convenient for staff to automatically feed the chemical sewage treatment tank. The drive motor is started to move the connecting frame along the limit screw inside the treatment tank body, and the scraper is squeezed with the treatment tank body under the action of the connecting spring, so that the scraper stirs the treatment reagents precipitated at the bottom of the treatment tank body, so that the treatment reagents are easy to fully react with the chemical sewage.

[0004] The above patent uses a scraper to squeeze the treatment tank body under the action of a connecting spring, so that the scraper stirs the treatment agent precipitated at the bottom of the treatment tank body, making it easier for the treatment agent to fully react with the sewage. However, when adding powder to the sewage, the powder may be added only once, causing the sewage and the powder to react too quickly, resulting in incomplete reaction. It is also possible that too much powder is added at one time, causing the excess powder to be discharged without producing a reaction effect, resulting in waste. Summary of the Invention

[0014] The present invention provides a sewage treatment pool with automatic feeding, which has the following beneficial effects: (1) In this invention, the cover plate rotates to release the seal on the discharge port, and the powder inside the storage frame is discharged from the discharge port into the sewage pool. The movement of the sleeve rod drives the stirring plate to move, and the movement of the stirring plate stirs the sewage inside the sewage pool to accelerate the dissolution rate of the powder. The powder can quickly react with the impurities in the sewage to form larger flocs, which are convenient for subsequent sedimentation or separation. By intermittently spreading the medicine, the efficiency of the reaction process can be maintained without reducing the effect due to excessive drug dosage or prolonged duration of drug effect.

[0015] (2) In this invention, the rotation of the impeller drives the rotating plate to rotate, and the rotation of the rotating plate pushes the impurities into the collection frame for storage, and pushes the floating impurities into the collection frame for collection.

[0016] (3) In this invention, the limit of the sliding frame will be released, and the sliding frame will be driven by the No. 1 spring to slide in the direction away from the sliding key, and the sliding frame will store the floating objects on the surface of the rotating plate, so as to prevent the impurities from sliding out of the rotating plate when the rotating plate pushes the impurities for collection. This setting can more effectively control the influence of buoyancy, and prevent the impurities from being washed away by the water flow or unevenly distributed when floating on the water surface, thereby improving the working efficiency of the rotating plate and the processing effect of impurity collection.

[0017] (4) In this invention, the rotation of the filter will scrape the impurities inside the collection frame to the side of the partition away from the rotating plate for collection, separating the floating impurities from the water surface, which can effectively remove pollutants in the water, reduce the concentration of suspended matter, and improve the treatment effect of sewage. This is of great significance for subsequent sewage treatment and avoids the influence of impurities in the water on the subsequent treatment process.

[0018] (5) In this invention, the movable end of the telescopic scraper will contact the filter when it moves to its original position, scraping off the impurities remaining on the surface of the filter to prevent the impurities from adhering to the filter when it returns to its original position. The remaining impurities will be re-mixed with the impurities in the sewage as new sewage flows in, causing the pores of the filter to be partially or completely blocked, reducing the filtering efficiency of the filter. Once the filter is blocked, the sewage treatment effect will deteriorate, and the filter may even need to be cleaned and replaced more frequently, increasing maintenance costs.

A No. 2 torsion spring is provided between the dredging rod 16 and the fixed plate 4. The No. 2 torsion spring is provided to drive the dredging rod 16 back to its original position. The cover plate 12 is in contact with the discharge port.

[0025] When this embodiment is working: when sewage needs to be treated, sewage will be injected into the sewage pool 1. After the sewage enters the sewage pool 1, the sewage will be added to the inside of the sewage pool 1, and the sewage will be stirred to make the sewage and the medicine powder fully mixed together, the impurities in the sewage will be degraded, the impurities will float on the water surface, and the sewage and impurities will be separated. After the sewage enters the sewage pool 1, the motor 2 will start, and the motor 2 will drive the screw rod 3 to rotate when it starts. The rotation of the screw rod 3 will drive the sleeve rod 7 to move. When the sewage enters the sewage pool 1, the float plate 9 will float due to the high density of the sewage. The floating of the float plate 9 will drive the elastic telescopic rod 10 to move. The movement of the elastic telescopic rod 10 will push the rotating rod 11 to rotate upward.

The up and down rotation of the push block 15 will drive the dredging rod 16 to rotate, and the rotation of the dredging rod 16 will dredge the discharge port. In the storage frame 5, the medicine powder may clump due to moisture, static electricity or other factors, resulting in the medicine powder being unable to smoothly pass through the discharge port into the sewage pool 1. Regularly dredging the discharge port can ensure that the medicine powder can be released smoothly to avoid caking or accumulation blocking the discharge port.
