Description

Technical Field

[0001] The present invention relates to the field of electrocatalytic phosphorus removal, and in particular to intelligent electrocatalytic biological phosphorus removal equipment. Background Art

[0002] Excessive phosphorus additions will cause algae to reproduce in large numbers. The algae will die and decompose, which will produce musty and foul odors in the water. They will also produce toxins. Therefore, phosphorus removal is required before discharge. Common phosphorus removal methods include biological phosphorus removal and chemical phosphorus removal. Electrochemical phosphorus removal technology uses aluminum or iron plates as electrodes. When an external power supply is applied, the anode loses electrons and is oxidized into corresponding metal cations. The metal cations combine with phosphate in the water to form insoluble precipitates, thereby achieving the purpose of removing phosphorus from the water.

[0003] Authorization announcement number CN214032061U discloses an electrocatalytic oxidation decontamination device, which mainly uses a particle filter set in the raw water tank to filter out impurity particles to avoid affecting the operating effect of electrocatalytic oxidation. At the same time, the particle filter can be adsorbed and fixed to the card slot in the raw water tank through an iron-absorbing layer. When it needs to be taken out for cleaning at a regular time, it can be taken out through the opening. The provided clamping block can facilitate the placement of a container for collecting waste in the middle, and the clamping block can be clamped and fixed by sliding in the chute. When the sewage enters the clean water tank, it is filtered through an ultrafiltration net and then filtered through activated carbon to adsorb particulate matter before it can be discharged or reused. However, when the device is actually used, the following defects still exist:

[0004] 1. When removing phosphorus from water through electrocatalysis, impurities in the water will turn into flocculent matter under the catalytic action of the electrodes and precipitate in the water. They are easily attached to the surface of the filter, affecting the fluidity of the water for phosphorus removal and purification. In addition, the flocculent matter accumulates at the bottom of the water, making it difficult to clean and treat the sediment separately. As a result, the sediment has a significant impact on phosphorus removal and circulation in the water, increasing the limitations of the electrocatalytic biological phosphorus removal and reducing the phosphorus removal rate.

[0005] 2. When electrocatalytic phosphorus removal is carried out on water bodies, the flocculent matter produced tends to float on the surface of the water body, and then adheres to the filter net in large quantities as the water body flows. It is not only difficult to settle, but also reduces the phosphorus removal and purification efficiency of the water body. Summary of the Invention

The spray head 61 is opposite to the vertical plane of the guide channel 91, which is convenient for discharging and cleaning the sediment after dephosphorization.

[0037] Furthermore, a limiting groove 68 is provided on one side of the interior of the drain box 63, and a vertically sliding float 67 is provided on the inner side of the limiting groove 68, and an electric contact 69 is provided on the top of the float 67.

[0038] In some embodiments, the raw water filter assembly 7 includes a filter cartridge 71, an annular filter tank 72, an outer gear ring 73, an annular guide groove 74, a guide block 75 and a convex filter plate 76. An annular guide groove 74 is provided on one side of the top of the dephosphorization box 1, and a guide block 75 is symmetrically provided on the inner side of the annular guide groove 74 for sliding fit. The bottoms of the two guide blocks 75 are connected to the filter cartridge 71. The raw water guide pipe 2 extends to the interior of the dephosphorization box 1 and the filter cartridge 71 and is perpendicular to the axis of the bottom of the filter cartridge 71. The outer gear ring 73 is installed on the outside of the filter cartridge 71, and the outer gear ring 73 is meshed with the gear 310. The middle of the bottom of the filter cartridge 71 A convex filter plate 76 is provided at the position, and the edge of the bottom of the filter cartridge 71 is a drain port. An annular filter groove 72 is provided at the middle position of the fixed bin inside the dephosphorization box 1, and the annular filter groove 72 is vertically opposite to the drain port at the bottom edge of the filter cartridge 71. The impurities discharged from the bottom surface of the filter cartridge 71 are collected by the annular filter groove 72, and the water to which the impurities adhere is separated by the filtration of the annular filter groove 72, and finally the water is vertically dropped for the introduction and dephosphorization of the water, while the filtered impurities are retained in the annular filter groove 72, which is easy to be recovered and processed later, so as to facilitate the preliminary filtration of impurities in the water body and improve the dephosphorization and purification efficiency.

[0039] Among them, the convex filter plate 76 is a conical structure, and the convex filter plate 76 is respectively opposite to the port of the raw water guide pipe 2 and the vertical surface of the guide pipe 8, so as to facilitate the use of the conical structure of the convex filter plate 76 to filter the water while causing impurities to slide out of the filter cylinder 71.

[0040] One side of the filter frame 93 is a liquid inlet, and the filter surface on the other side of the filter frame 93 is in contact with the connection point of the drainage channel 11. A sedimentation tank is provided at the bottom of the filter frame 93, and the sedimentation tank is connected to the drain valve 64, so that the electrocatalyzed water and sediment can enter one side of the filter frame 93, so as to finally filter and separate the sediment and water, and carry out subsequent purification of the water.

[0041] When the equipment is performing electrocatalytic biological phosphorus removal, the raw water can be introduced into the phosphorus removal box 1 through the raw water guiding pipe 2. Then, under the structural start-up of the sedimentation and filtration mechanism 3, the gear 310 and the first bevel gear set 32 are driven to rotate in conjunction. At this time, as the gear 310 rotates, the outer ring gear 73 is driven to rotate, prompting the outer ring gear 73 to drive the filter cartridge 71 to rotate under the guided sliding of the guide block 75 and the annular guide groove 74, thereby driving the convex filter plate 76 to rotate. Therefore, the raw water introduced into the raw water guiding pipe 2 is filtered by the convex filter plate 76, and the water and impurities are preliminarily separated, and the impurities are introduced into the annular filter groove 72 for collection and filtration. Therefore, after the water is preliminarily filtered, it is introduced into the guide pipe 8 and the guide channel 91 to flow, and the electrocatalytic phosphorus removal of the water body is performed.

[0042] The meshing of the first bevel gear set 32 drives the rotating rod 33 to rotate in conjunction, and the rotating rod 33 drives the multiple sets of U-shaped seats 34 and the movable rod 35 to move back and forth, so that the movable rod 35 drives the sedimentation screen 39 arranged on the inner side of the guide channel 91 to rise and fall, and the rotating rod 33 synchronously drives the second bevel gear set 36 to mesh, prompting the second bevel gear set 36 to drive the scraper plate 38 to rotate on the inner side of the filter frame 93, scraping and cleaning the filter surface of the filter frame 93. At this time, when the water flows into the guide channel 91, the staggered blocks are arranged. The plate 92 extends the flow path of the water body, and then, with the cooperation of the three cathode electrodes 42 and the anode electrode 43, the water body in the diversion channel 91 is electrocatalytically dephosphorized, and the flocculent produced by the dephosphorization is precipitated on the undulating sedimentation screen plate 39 to avoid floating on the surface of the water liquid. Then, it is introduced into the filter screen frame 93 with the flow of the water body to filter the water body and sediment after dephosphorization, and finally the filtered water body is introduced into the drainage channel 11 and enters the clean water tank 5 for subsequent purification work, thereby improving the biological dephosphorization and purification efficiency of the water body.

[0043] In some embodiments, this embodiment is further improved on the basis of the above embodiments, and the parts that are the same as the above embodiments are not repeated here.

[0044] like Figures 1-4 As shown, the sediment is accumulated at the bottom of the filter frame 93 through the filtration of the filter frame 93, and the rotation of the scraper plate 38 is coordinated to prevent the sediment from adhering to the filtration layer of the filter frame 93. When the sediment needs to be cleaned, the drain valve 64 is started to open the channel between the dephosphorization box 1 and the drain box 63, so that the sediment is forced to flow vertically downward from the filter frame 93 into the drain valve 64 and the drain box 63, and under the setting of the filter mesh groove 66, the sediment and part of the water body are filtered twice, thereby realizing the automatic collection function of the sediment.

[0045] When water enters the drainage box 63, the float plate 67 can be gradually raised and lowered as the water is introduced, and the float plate 67 drives the electric contact 69 to rise vertically under the guidance of the limit groove 68, and finally the electric contact 69 and the electric contact block 610 contact each other for intelligent sensing, so as to transmit a signal to automatically close the drainage valve 64, and avoid excessive outflow of water from the dephosphorization area in the dephosphorization box 1, so as to intelligently limit the outflow of water, and under the start of the water pump 65, the water filtered by the drainage box 63 is introduced into the spray head 61 from the circulation pipe 62 and sprayed out, so that the water flows into the diversion channel 91 again, and circulates for dephosphorization and purification. The automatic sediment discharge and water circulation of this structure are used to increase the intelligent dephosphorization operation of the device, avoid sediment accumulation in the filter frame 93, affect the flow of water and dephosphorization efficiency, and solve the problem that sediment is difficult to automatically discharge and collect.

[0046] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the present invention's specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of patent protection of the present invention.
