Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically a wastewater treatment device that facilitates chemical dosing. Background Technology

[0002] Wastewater treatment refers to the process of treating wastewater using physical, chemical, and biological methods to purify it, reduce pollution, and ultimately achieve wastewater recycling and reuse, thus making full use of water resources. In the field of wastewater treatment, traditional dosing and mixing processes have shortcomings.

[0003] Traditional equipment often employs fixed agitators or manual dosing, resulting in uneven mixing of chemicals and wastewater, leading to unstable treatment effects. This is especially problematic when treating high-concentration or complex wastewater, where localized over- or under-dosing of chemicals can occur, affecting subsequent processes such as flocculation and sedimentation. Existing filtration devices are mostly fixed mesh structures, which are ineffective at intercepting suspended solids and impurities and lack automatic cleaning mechanisms. After long-term operation, filter clogging leads to reduced flow, requiring frequent shutdowns for manual cleaning, increasing maintenance costs and downtime. Furthermore, most systems use multiple chemicals added in tandem without independent control channels, increasing the risk of cross-contamination. Therefore, a wastewater treatment device with easy-to-dosing capabilities is needed. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] Based on the problems of existing wastewater treatment devices, the present invention provides a preferred embodiment of a wastewater treatment device that facilitates chemical dosing, for example... Figure 1-4 As shown: A wastewater treatment device for easy dosing includes a support leg 1, a wastewater treatment tank 2 fixedly mounted on the top of the support leg 1, a control display box 3 fixedly mounted on the outer wall of the support leg 1, a fixed top cover 4 fixedly mounted on the top of the wastewater treatment tank 2 by fixing bolts, support plates 41 fixedly mounted on the outer wall of the fixed top cover 4, and there are three sets of support plates 41. A wastewater inlet pipe 5 is connected to the top of the fixed top cover 4, and a flow control valve 51 is sleeved on the outer wall of the wastewater inlet pipe 5. The bottom of the wastewater treatment tank 2 is connected to... A discharge pipe 6 is provided, and a collection tank 7 is provided below the discharge pipe 6; a chemical dosing wastewater treatment component 8 is provided, which is located inside the wastewater treatment tank 2 and above the fixed top cover 4; the chemical dosing wastewater treatment component 8 includes: a filtration and mixing section 81, which is located above the fixed top cover 4 and inside the wastewater treatment tank 2; and a chemical dosing section 82, which is located above the fixed top cover 4 and outside and above the filtration and mixing section 81.

[0025] The filtration and mixing section 81 includes: a filter frame 811, which is fixedly installed on the inner wall of the wastewater treatment tank 2; a motor 813, which is mounted above a fixed top cover 4 via a motor cover, and the motor cover is fixedly installed on the top of the fixed top cover 4; the bottom circumference of the inner wall of the filter frame 811 is provided with equally spaced drainage holes 812; the output end of the motor 813 is provided with a rotating rod 814 via a coupling, and the rotating rod 814 moves sequentially through the top of the fixed top cover 4, the top of the filter frame 811, and extends into the interior of the wastewater treatment tank 2.

[0026] A collar 815 is fixedly installed on the outer wall of the rotating rod 814, and the collar 815 is located above the filter frame 811. A crank support arm 816 is fixedly installed on the outer wall of the collar 815. A push scraper 817 is fixedly sleeved on the outer wall of the crank support arm 816, and the push scraper 817 extends to the bottom of the inner wall of the filter frame 811.

[0027] The bottom of the filter frame 811 is connected to a debris collection frame 818, and the inner wall of the debris collection frame 818 is provided with a water leakage hole. The bottom of the debris collection frame 818 is connected to a discharge pipe 819, which movably penetrates the inner wall of the wastewater treatment tank 2 and extends to one side of the outer wall of the wastewater treatment tank 2. A control valve 8110 is fitted on the outer wall of the discharge pipe 819.

[0028] A mounting block is fixedly installed at the bottom of the rotating rod 814, and stirring blades 8111 are fixedly installed at equal intervals on the outer circumference of the mounting block. A second collar 8112 is provided above the mounting block, and there are two sets of them. The outer wall of the rotating rod 814 is fitted on the collar, which is located below the filter frame 811 and above the mounting block, respectively. An arc-shaped mixing rod 8113 is fixedly installed between the second collars 8112, and there are two sets of them, which are arranged symmetrically.

[0029] Furthermore, in this embodiment, a rotating rod 814 drives a scraper 817 to continuously scrape the filter cake layer at the bottom of the inner wall of the filter frame 811, preventing blockage of the drainage holes 812 and ensuring stable filtration efficiency. In conjunction with the drainage holes on the inner wall of the debris collection frame 818, water and impurities are separated, preventing water accumulation from affecting the slag discharge efficiency. At the same time, the stirring blade 8111 is driven by the rotating rod 814 to form an axial mixing flow, accelerating the fusion of the reagent and wastewater. In conjunction with the arc-shaped mixing rod 8113, the wastewater is pushed from the center towards the tank wall, eliminating mixing dead zones and ensuring uniform distribution of the reagent, forming complex turbulence in the tank.

[0030] Example 2:

[0031] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is further obtained: the dosing part 82 includes: a support frame 821, which is fixedly installed on the top of the support plate 41, and there are three sets of the support frame 821; an installation ring plate 826, which is fixedly installed on the bottom of the inner wall of the fixed top cover 4; a sample extraction tube 828, which is connected to the outer wall of the wastewater treatment tank 2 and located below the control valve 8110; and three independent drug storage cylinders 822 are fixedly installed on the inner wall of the support frame 821 for independently placing different required additives, and a delivery pump 823 is provided on the inner wall of the independent drug storage cylinder 822.

[0032] The connection port of the delivery pump 823 is connected to a delivery pipe 824, which sequentially passes through the bottom of the independent medicine storage cylinder 822, the top of the fixed top cover 4, and the top of the mounting ring 826, and extends into the interior of the fixed top cover 4.

[0033] A flow control valve 825 is movably sleeved on the outer wall of the delivery pipe 824, and the flow control valve 825 is located below the independent medicine storage cylinder 822. An independent nozzle 827 is connected to the other end of the delivery pipe 824.

[0034] Furthermore, this embodiment features an independent storage tank 822 for storing different reagents, preventing cross-contamination and ensuring reagent purity. Combined with a flow control valve 825 and a delivery pump 823, the dosage can be dynamically adjusted based on real-time monitoring data. Simultaneously, the delivery pipe 824 and independent nozzle 827 ensure sufficient contact between the reagent and wastewater. The extraction and mixing sample tube 828 collects wastewater samples in real-time, monitoring parameters such as turbidity and pH, providing a basis for the dosing strategy.

[0035] During operation, the overall workflow is as follows: Wastewater enters the wastewater treatment tank 2 through the wastewater inlet pipe 5, and the inlet flow rate is adjusted by the flow control valve 51. The wastewater undergoes preliminary filtration and mixing with chemicals in the filtration and mixing section 81. Based on the water quality parameters, various chemicals are added in proportion at the dosing section 82. The mixed wastewater undergoes a chemical reaction in the tank, generating precipitates. The precipitates are discharged through the discharge pipe 2 819, and the treated clean water flows into the collection tank 7 through the discharge pipe 1 6.

[0036] Furthermore, wastewater enters wastewater treatment tank 2 through wastewater inlet pipe 5, first flowing into filter round frame 811. Large particulate impurities in the wastewater are intercepted by the drainage holes 812 at the bottom of the inner wall of filter round frame 811, forming a filter cake layer. Next, motor 813 drives rotating rod 814 to rotate, causing the crank support arm 816 on collar one 815 and push scraper 817 to rotate synchronously. Push scraper 817 adheres tightly to the bottom of the inner wall of filter round frame 811, scraping the filter cake layer into debris collection frame 818. Impurities in debris collection frame 818 are discharged through discharge pipe two 819, and control valve 8110 controls the timing of sludge discharge.

[0037] Furthermore, the mounting block at the bottom of the rotating rod 814 drives the stirring blade 8111 to rotate, drawing wastewater upwards from the bottom to form an axial mixing flow. The arc-shaped mixing rod 8113 between the two sets of collar rings 8112 rotates synchronously with the rotating rod 814, pushing the wastewater from the center towards the tank wall, enhancing the radial mixing effect.

[0038] Furthermore, the reagent added at the dosing point 82 is sprayed into the wastewater through an independent nozzle 827 and is immediately and evenly dispersed by the stirring blades 8111 and the arc-shaped mixing rod 8113. The pusher scraper 817 continuously scrapes off the filter cake layer on the surface of the filter frame 811 to prevent clogging of the drainage holes 812. Drainage holes are provided on the inner wall of the debris collection frame 818 to prevent water accumulation from affecting the slag discharge efficiency.

[0039] Furthermore, three independent storage tanks 822 store flocculants, coagulants, and pH adjusters respectively, avoiding cross-contamination. A delivery pump 823 transports the chemicals from the independent storage tanks 822 to independent nozzles 827 via delivery pipes 824, and a control valve 825 adjusts the dosage. Next, real-time monitoring is performed, and a mixed sample tube 828 extracts wastewater from the tank to monitor parameters such as turbidity and pH. The control display box 3 automatically adjusts the speed of the delivery pump 823 and the opening of the control valve 825 according to preset thresholds.

[0040] When the influent flow rate changes, the flow control valve 51 is linked with the transfer pump 823 to maintain a constant reagent dosage ratio. The rotation speed of the agitator blade 8111 is automatically adjusted according to the wastewater concentration to ensure mixing effect. When the sediment accumulates to the set height, the control valve 8110 opens, and the sludge is discharged through the discharge pipe 819. The treated clean water flows into the collection tank 7 through the discharge pipe 6, and is discharged or reused after meeting the standards.

[0041] Start-up preparation:

[0042] Check the reagent level in the storage tank 822 and confirm that the transfer pump 823 is functioning normally. Close the control valve 8110 of the discharge pipe 2 819 and open the flow control valve 51. Wastewater enters the filter frame 811, where large particles are intercepted, and clean water flows into the tank. The motor 813 starts, and the rotating rod 814 drives the stirring blade 8111 and the arc-shaped mixing rod 8113 to mix the wastewater. The control display box 3 automatically adjusts the reagent addition by the transfer pump 823 based on real-time monitoring data. After the treatment cycle is completed, open the control valve 8110 to discharge the sludge. Turn off the motor 813 and the transfer pump 823, and close the flow control valve 51 after the wastewater has been drained.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
