Description

Technical Field

[0001] The invention relates to the technical field of water purification reactors, and in particular to a composite water purification reactor for decarbonization and dephosphorization. Background Art

[0002] Carbon removal and phosphorus removal are important links in the water treatment process, aiming to remove carbon and phosphorus in water to reduce eutrophication and improve water quality. Carbon removal mainly refers to the removal of organic carbon or inorganic carbon in water. In sewage treatment, carbon is removed from water by adding chemical agents to react with carbon in water to generate precipitation or gas. The purpose is to reduce the organic matter content in water, reduce chemical oxygen demand and biochemical oxygen demand, and prevent organic matter from decomposing and consuming oxygen in water, resulting in water quality deterioration. Phosphorus removal is to treat phosphorus in water. Phosphorus is one of the main nutrients for eutrophication of water. Excessive phosphorus can cause algae to reproduce in large numbers and affect water quality. Water purification reactor is a key equipment in water treatment system for removing impurities and improving water quality. Chemical agents are added to react with pollutants in water to generate water-insoluble precipitation or gas, and then pollutants are removed from water by solid-liquid separation or gas-liquid separation. When water purification reactors use chemical reagents to remove carbon and phosphorus from water, the reaction is often insufficient, resulting in some unreacted precipitated carbon and phosphorus remaining in the water. The resulting precipitates are not easy to be removed in the water purification reactor, so we proposed a composite water purification reactor for carbon removal and phosphorus removal.

[0007] 2. The present invention provides a stirring device, and the spiral plate fixed on the surface of the rotating rod and the stirring paddle at the bottom rotate, thereby accelerating the reaction between water and chemical reagents and making the reaction more complete.

[0008] 3. The present invention sets a filtering device, and purified water is discharged from the water outlet pipe, while the sediment is filtered by the filter plate and deposited on the surface of the filter plate. The driving shaft of the motor starts to rotate, driving the rotation of the filter plate 1 and the semicircular plate 1. During the rotation of the filter plate 1, it will pass through the scraper rod, so that the sediment on the surface of the filter plate 1 can be easily fallen off under the push of the scraper rod, thereby avoiding the accumulation and blockage of the sediment and ensuring the continuous and efficient operation of the filter plate. At the same time, the rotation of the filter plate 1 also scrapes off the sediment on the surface of the filter plate 2, so that the sediment on the surface of the filter plate 2 can also be scraped off to avoid the blockage of the filter screen. The fallen sediment is guided by the oblique plate to the opening formed by the rotation of the semicircular plate 1, thereby ensuring the smooth discharge of the sediment and preventing the sediment from falling on the surface of the semicircular plate 2, thereby avoiding possible blockage and cleaning problems.

[0009] 4. The present invention provides a discharging device, and when the sediment completely falls to the bottom of the inner wall of the water purifier box, the motor starts to accelerate and rotate, driving the rotation of the cylinder, thereby causing the rectangular inclined plate fixed on the folding rod to rotate accordingly. The rotation of the rectangular inclined plate generates a strong centrifugal force, which scrapes up the sediment near the center, avoiding the accumulation and solidification of the sediment, and the scraped sediment moves along the inclined surface of the rectangular inclined plate toward the rectangular hole position, so that the sediment is close to the discharging port for easy discharge, avoiding the random diffusion of the sediment inside the box, and the inclined push plate rotates and scrapes up the sediment accumulated on the periphery. During the rotation of the inclined push plate, the sediment is subjected to an upward thrust and gradually moves upward. The sediment is rotated and moved to the discharge pipe under the push of the inclined push plate, and is smoothly discharged through the discharge port, ensuring the smooth discharge of the sediment, avoiding the accumulation and residue of the sediment at the bottom of the box, and the scraper also scrapes the inner wall of the box during the rotation to prevent the sediment from remaining on the inner wall of the box.
