Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically to a comprehensive organic resource utilization treatment device for domestic blackwater. Background Technology

[0002] Domestic blackwater refers to mixed sewage that includes toilet wastewater, high-concentration organic wastewater from kitchens, washing wastewater, and leachate from some food waste. Its water quality is complex and pollutant-laden, containing large amounts of biodegradable organic matter such as carbohydrates, proteins, and fats, along with high levels of ammonia nitrogen, high COD (chemical oxygen demand), high BOD (biochemical oxygen demand), and small amounts of heavy metals and pathogenic microorganisms. Improper treatment and direct discharge can severely pollute surface water, groundwater, and soil, disrupting the ecological balance and threatening human health. With the acceleration of urbanization, the advancement of rural revitalization strategies, and increasingly stringent environmental regulations, the harmless treatment and resource utilization of domestic sewage has become an important issue in ecological environmental protection.

[0003] While current domestic blackwater treatment methods can reduce pollutant concentrations, they have significant limitations. The addition of chemicals and the mixing reaction are crucial aspects affecting treatment efficiency, resource recovery, and ease of operation and maintenance. On one hand, current chemical dosing relies heavily on manual operation, which is cumbersome and labor-intensive. On the other hand, the mixing and blending of blackwater is mostly done in a single direction, lacking an efficient forward and reverse mixing structure, resulting in poor mixing effects, dead zones, and uneven mixing with chemicals. This significantly reduces wastewater treatment efficiency and fails to meet practical application requirements.

[0004] Therefore, there is a need to provide a comprehensive organic resource utilization treatment device for domestic blackwater, which aims to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a comprehensive organic resource utilization treatment device for domestic blackwater, which aims to solve the technical problems mentioned in the background art.

The second bevel gear is rotatably connected to the fixed shaft through a fifth rotating shaft, and the second bevel gear is also meshed with the first bevel gear, which is fixedly installed on the first rotating sleeve.

[0015] As a further embodiment of the present invention, the forward and reverse stirring mechanism further includes a rack for driving the first rotating shaft sleeve to rotate. A rotating gear is fixedly connected to the first rotating shaft sleeve. The rack is meshed with the outer side of the rotating gear. The rack is slidably connected to a rack slide block. The rack slide block is rotatably mounted on a fixed shaft. One end of the rack is rotatably connected to one end of a rotating connecting rod via a fourth rotating shaft.

[0021] The forward and reverse stirring mechanism effectively eliminates dead zones in the mixing process, improves the uniformity of the reagents, adapts to the needs of multiple treatment stages, enhances reaction efficiency, and better promotes the degradation of organic pollutants. Furthermore, this convective stirring method reduces the wear of the stirring blades caused by sludge deposition, extends the blades' service life, further reduces equipment maintenance costs, and facilitates subsequent wastewater treatment.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0037] Example 1

[0038] See Figures 1-5 A comprehensive organic resource treatment device for domestic blackwater includes a pretreatment tank 1 and a main treatment tank 2. The pretreatment tank 1 is equipped with an inlet pipe 5, and the main treatment tank 2 is fixedly connected to a drain pipe 48 with a valve. The pretreatment tank 1 is internally connected to the main treatment tank 2 via a guide pipe 4. The pretreatment tank 1 is equipped with a slag discharge pipe 49. The pretreatment tank 1 is fixedly installed on the main treatment tank 2 via a support column 3. The device also includes:

[0039] The pretreatment mechanism is installed inside the pretreatment tank 1 and is used to perform vibration filtration treatment on the black water in the pretreatment tank 1. The pretreatment mechanism includes a filter plate 6 for filtration and a filter-driven rotating ring 8. The rotating ring 8 is rotatably mounted on the main treatment tank 2 via a first rotating shaft 11.

[0040] Furthermore, the pretreatment mechanism also includes a first contact ball 7 and a second contact ball 9 for driving the filter plate 6 to vibrate and filter. The first contact ball 7 and the second contact ball 9 are arranged correspondingly for contact. The first contact ball 7 is connected to the filter plate 6, and the second contact ball 9 is connected to the rotating ring 8. The rotating ring 8 is fixedly installed on the first rotating shaft 11 by connecting the stirring rod 10.

[0041] Furthermore, the pretreatment mechanism also includes a motor 14 for driving the rotating ring 8 to rotate. A worm gear 12 is fixedly connected to the first rotating shaft 11, and a worm 13 is meshed on the worm gear 12. The worm 13 is fixedly connected to the output end of the motor 14, and the motor 14 is fixedly installed on the main treatment tank 2.

[0042] Preferably, when treating domestic blackwater, the blackwater is mainly injected into the pretreatment tank 1 through the inlet pipe 5. The filter plate 6 in the pretreatment tank 1 performs primary filtration. To further improve filtration efficiency, the output shaft of the motor 14 drives the worm gear 13 to rotate. Under the meshing connection between the worm gear 13 and the worm wheel 12, the docking stirring rod 10 on the first rotating shaft 11 is driven to rotate. The docking stirring rod 10 correspondingly drives the second contact ball 9 on the rotating ring 8 to rotate. Under the adaptive contact connection between the second contact ball 9 on the rotating ring 8 and the first contact ball 7 on the filter plate 6, the filter plate 6 can be driven to perform continuous vibration filtration, thereby further improving the filtration efficiency of the filter plate 6, which facilitates subsequent purification treatment. Unfiltered residue can be discharged from the slag discharge pipe 49.

[0043] This vibration filtration pretreatment method can effectively improve the impurity interception efficiency and reduce the pollutant load. At the same time, vibration filtration pretreatment can efficiently remove some hard and fine impurities, significantly reduce the impurity load of subsequent process units, avoid the scouring and wear of impurities on pipelines and other components, and extend the service life of the whole machine.

[0044] Example 2

[0045] like Figures 1 to 8 As shown, this embodiment, based on embodiment 1, also includes a drug addition mechanism, which is installed on the main treatment tank 2 and synchronously driven by the pretreatment mechanism. It is used to selectively add drugs to the main treatment tank 2. The drug addition mechanism includes an infusion cylinder 25 for injecting drugs. The infusion cylinder 25 selectively adds drugs through forward and reverse driving of the second rotating shaft 16.

[0046] Furthermore, the drug addition mechanism also includes a push piston 24, an injection pipe 26, and a suction pipe 28 for driving the infusion cylinder 25 to inject liquid. The push piston 24 is slidably connected to the inside of the infusion cylinder 25 by a push rod 23. The infusion cylinder 25 is connected to the inside of the main treatment tank 2 through the injection pipe 26. An injection check valve 27 is provided on the injection pipe 26. The infusion cylinder 25 is also connected to the inside of the storage tank 30 through the suction pipe 28. A suction check valve 29 is provided on the suction pipe 28. A replenishment pipe 31 is provided on the storage tank 30.

[0047] Furthermore, the drug addition mechanism also includes a cam 19 for driving the push piston 24 to reciprocate. The other end of the push rod 23 is fixedly connected to a push plate 21. A return spring 22 is provided at the connection between the push plate 21 and the infusion cylinder 25. The cam 19 is rotatably mounted on one side of the push plate 21. The cam 19 is rotatably mounted on an L-shaped fixing frame 20 via a third rotating shaft 18. The L-shaped fixing frame 20 is fixedly mounted on the main treatment tank 2. The third rotating shaft 18 is mounted on one end of the second rotating shaft 16 via a one-way bearing 17.

[0048] Preferably, in this embodiment, when stirring in the main treatment tank 2, and when adding and purifying agents are required, the motor 14 drives the worm gear 13 to rotate in the forward direction. At this time, the synchronous drive of the synchronous belt 15 drives the second rotating shaft 16 to rotate in the forward direction. Then, under the unidirectional traction of the one-way bearing 17, the cam 19 on the third rotating shaft 18 is driven to rotate continuously. At this time, under the eccentricity of the cam 19 and the reset action of the return spring 22, the push piston 24 is driven to move back and forth inside the infusion cylinder 25. Then, under the unidirectional action of the liquid-drawing one-way valve 29 on the liquid-drawing pipe 28 and the liquid-injection one-way valve 27 on the liquid-injection pipe 26, the treatment agent in the storage tank 30 can be drawn and placed into the main treatment tank 2, thereby facilitating better resource utilization in the main treatment tank 2.

[0049] When no medication needs to be added, the output shaft of motor 14 simply rotates in the opposite direction. Under the unidirectional action of the one-way bearing 17, the rotation of the second rotating shaft 16 cannot drive the third rotating shaft 18 to rotate accordingly, thus completing the medication addition and shut-off process, which facilitates adjustable use.

[0050] It should be noted that the output shaft of motor 14 can be driven in both forward and reverse directions.

[0051] This synergistic approach of vibration filtration and chemical dosing significantly improves the overall pretreatment effect. Furthermore, the controlled chemical dosing can be achieved by rotating the motor in both directions, adapting to water quality fluctuations and preventing chemical waste and secondary pollution. This integrated design also eliminates the challenges of debugging multiple devices simultaneously. Maintenance personnel can switch between "filtration + chemical dosing" and "separate filtration" modes simply by controlling the motor's rotation direction, eliminating the need for cumbersome manual operations and multi-device coordination, thus greatly reducing labor intensity.

[0052] Example 3

[0053] like Figures 1 to 11 As shown, this embodiment, based on the above embodiment, also includes a forward and reverse stirring mechanism, which is installed inside the main treatment tank 2 and synchronously driven by the pretreatment mechanism. It is used to perform forward and reverse stirring treatment of the black water in the main treatment tank 2 for mixing chemicals. The forward and reverse stirring mechanism includes a first stirring paddle 40 and a second stirring paddle 47 for cyclic forward and reverse stirring. The first stirring paddle 40 and the second stirring paddle 47 are driven by the rotation of the rotating connecting rod 32. The rotating connecting rod 32 is driven by the forward and reverse rotation of the second rotating shaft 16.

[0054] Furthermore, the forward and reverse stirring mechanism also includes a first rotating bushing 37 and a second rotating bushing 45 for driving the first stirring paddle 40 and the second stirring paddle 47 to rotate in opposite directions. The first rotating bushing 37 and the second rotating bushing 45 are both rotatably mounted on the outside of the fixed shaft 36, which is fixedly mounted inside the main treatment tank 2. The first stirring paddle 40 is fixedly mounted on the first rotating bushing 37 via the first traction rod 39, and the second stirring paddle 47 is fixedly mounted on the second rotating bushing 45 via the second traction rod 46. The first rotating bushing 37 and the second rotating bushing 45 are arranged to rotate in opposite directions.

[0055] Furthermore, the forward and reverse stirring mechanism also includes a second bevel gear 43 for driving the first rotating bushing 37 and the second rotating bushing 45 to rotate in opposite directions. A third bevel gear 44 is fixedly connected to the second rotating bushing 45, and the second bevel gear 43 is meshed with the third bevel gear 44. The second bevel gear 43 is rotatably connected to the fixed shaft 36 through the fifth rotating shaft 42, and a first bevel gear 41 is also meshed with the second bevel gear 43. The first bevel gear 41 is fixedly installed on the first rotating bushing 37.

[0056] Furthermore, the forward and reverse stirring mechanism also includes a rack 34 for driving the first rotating bushing 37 to rotate. A rotating gear 38 is fixedly connected to the first rotating bushing 37. The rack 34 is meshed with the outer side of the rotating gear 38. The rack 34 is slidably connected to the rack slide 35. The rack slide 35 is rotatably mounted on the fixed shaft 36. One end of the rack 34 is rotatably connected to one end of the rotating connecting rod 32 through the fourth rotating shaft 33. The other end of the rotating connecting rod 32 is fixedly connected to the second rotating shaft 16. The second rotating shaft 16 is rotatably mounted on the main processing tank 2, and the second rotating shaft 16 is rotatably connected to the first rotating shaft 11 through the synchronous belt 15.

[0057] Preferably, in this embodiment, regardless of whether the output shaft of the motor 14 rotates in the forward or reverse direction, it can drive the second rotating shaft 16 to rotate in the forward or reverse direction accordingly. At this time, the second rotating shaft 16 drives the rotating connecting rod 32 to rotate accordingly. Thus, under the rotational traction of the fourth rotating shaft 33 and the adaptive sliding connection of the rack slide 35, the rack 34 can be driven to move to the side of the rotating gear 38, thereby driving the first rotating bushing 37 on the rotating gear 38 to rotate in the forward or reverse direction. At this time, the first rotating bushing 37 drives the first stirring paddle 40 on the first traction rod 39 to perform stirring operations.

[0058] At the same time, the rotation of the first rotating bushing 37 drives the first bevel gear 41 to rotate accordingly. Thus, with the first bevel gear 41 meshing with the second bevel gear 43 and the third bevel gear 44 one by one, the second rotating bushing 45 can drive the second stirring paddle 47 on the second traction rod 46 to perform stirring operations. The first stirring paddle 40 rotates on the outer periphery, and the second stirring paddle 47 rotates on the inner periphery, and the rotation directions of the two are always set in opposite directions, thereby further improving the mixing efficiency in the main treatment tank 2, thereby further improving the treatment efficiency of the reagents, and achieving good treatment of domestic blackwater.

[0059] This method of mixing with opposing blades inside and out effectively eliminates dead zones, improves the uniformity of reagent mixing, adapts to the needs of multiple treatment stages, enhances reaction efficiency, and better promotes the degradation of organic pollutants. Furthermore, this convective mixing method reduces wear on the mixing blades due to sludge deposition, extends blade life, further reduces equipment maintenance costs, and facilitates subsequent wastewater treatment.

[0060] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
