Abstract
Description
Technical Field
[0001] This application relates to the field of wastewater treatment technology, specifically wastewater flocculation and sedimentation treatment equipment. Background Technology
[0002] Wastewater flocculation sedimentation treatment equipment is a key piece of equipment used to remove suspended solids in wastewater treatment. Its core principle is to achieve solid-liquid separation through two processes: flocculation and sedimentation.
[0003] For example, the patent with publication number CN211946598U discloses a wastewater flocculation sedimentation treatment device. The device can add an appropriate amount of flocculant into the flocculation chamber through the dosing port. Wastewater enters the flocculation chamber, the first sedimentation tank, the second sedimentation tank and the filter tank in sequence through the inlet. The flocculated impurities settled in the first sedimentation tank and the flocculated impurities settled in the second sedimentation tank are discharged through the first sewage outlet and the second sewage outlet, respectively. Finally, the treated wastewater is discharged through the outlet.
[0004] While the aforementioned patent can treat wastewater, during the discharge process, the sludge often contains impurities such as sand, fibers, and hard particles. When the discharge flow rate is too high, the impact of these impurities on the inner wall of the pipe is significantly enhanced. Consequently, the pipe will continuously rub against the inner wall during discharge, which may cause the inner wall of the pipe to wear down and thin after long-term use, leading to the risk of leakage.
[0005] Therefore, it is necessary to provide wastewater flocculation and sedimentation treatment equipment to solve the above problems.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0032] like Figure 1 and Figures 3-4 As shown, this application provides a wastewater flocculation and sedimentation treatment device, including a water tank 1, the interior of which is equipped with a treatment component 2, which is suitable for treating wastewater, specifically:
[0033] Processing component 2 includes a water inlet pipe 21 disposed on the water tank 1, one end of which extends into the interior of the water tank 1, and extends from left to right inside the water tank 1. Figure 3 The pool 1 is provided with an inlet chamber 22, a flocculation chamber 24, a sedimentation chamber 27 and a clear water chamber 28 in sequence. One end of the inlet pipe 21 extends into the pool 1 and is located inside the inlet chamber 22 so that sewage can be discharged into the inlet chamber 22.
[0034] A connecting port 23 is provided between the water inlet chamber 22 and the flocculation chamber 24 so that the water in the water inlet chamber 22 can enter the flocculation chamber 24 through the connecting port 23. A vertical plate 251 is provided between the flocculation chamber 24 and the sedimentation chamber 27. Multiple sets of through grooves 25 are provided on the vertical plate 251 so that the water in the flocculation chamber 24 can enter the sedimentation chamber 27 through the through grooves 25.
[0035] Multiple sets of cover plates are detachably installed on the top of the water tank 1, and multiple sets of stirring parts are set on the cover plates. The stirring parts can be a rotating structure driven by a motor. For example, a motor is installed on the cover plate, and a stirring shaft is fixedly installed on the output end of the motor. Multiple sets of stirring blades are set on the stirring shaft. Then, under the drive of the motor, the stirring blades are rotated by the stirring shaft to stir the water flow.
[0036] Multiple stirring sections are respectively installed inside the water inlet chamber 22, the flocculation chamber 24 and the sedimentation chamber 27, and the structure and principle of the multiple stirring sections are the same, only the size and blade position are different.
[0037] Continue to refer to Figure 3 Inside the flocculation chamber 24, a guide tube 241 is provided. The stirring part on the flocculation chamber 24 is located inside the guide tube 241. A feeding pipe (not shown in the figure) is provided inside the flocculation chamber 24 to facilitate the feeding of flocculant into the flocculation chamber 24 and to stir it under the drive of the stirring part so as to mix it with the sewage.
[0038] Furthermore, when the wastewater in the flocculation chamber 24 is stirred in the stirring section, the water will circulate up and down in the guide tube 241. This is existing technology, and the specific structure and principle will not be elaborated here.
[0039] A treatment box 26 is fixedly installed on the inner wall of the sedimentation chamber 27. A side plate 261 is provided on the side of the treatment box 26 near the flocculation chamber 24. The side plate 261 is a certain distance away from the vertical plate 251, forming a flow gap. The two ends of the side plate 261 are attached to the inner side of the sedimentation chamber 27, so that the sewage flowing from the flocculation chamber 24 into the sedimentation chamber 27 can only flow into the bottom of the sedimentation chamber 27 through the flow gap.
[0040] It should be noted that, except for the side near the vertical plate 251, the other three sides of the processing box 26 are in contact with the inner wall of the sedimentation chamber 27, and the processing box 26 is a through-type structure. At the same time, multiple sets of inclined plates are set inside the processing box 26, so that inclined channels are formed between each set of inclined plates.
[0041] As the amount of wastewater in the flocculation chamber 24 gradually increases, it will enter the bottom of the sedimentation chamber 27 through the channel 25. Since the other three sides of the treatment box 26 are in contact with the inner wall of the sedimentation chamber 27, the wastewater can only move upward through the inclined channel from the bottom of the treatment box 26. Thus, the impurities in the wastewater can be blocked by the inclined plate and fall back into the bottom of the sedimentation chamber 27 under the action of gravity.
[0042] The rotating shaft of the stirring part in the sedimentation chamber 27 passes between multiple sets of inclined plates and is at a certain distance from the multiple sets of inclined plates to avoid interference with the rotation of the stirring part;
[0043] Continue to refer to Figure 3 and Figure 4 A transition box 31 is fixedly installed on the inner wall of the sedimentation chamber 27. The transition box 31 is located above the treatment box 26. Multiple sets of water collection tanks 29 are fixedly installed between the transition box 31 and the side plate 261. Multiple sets of drain ports 3 adapted to the water collection tanks 29 are opened on the transition box 31 so that the clean water that submerges the water collection tanks 29 can enter the transition box 31 from the drain ports 3.
[0044] A water inlet 32 is provided through the transition box 31 and the clear water chamber 28 so that clear water can enter the clear water chamber 28 through the water inlet 32. A buffer box 33 can be provided at the water inlet 32. The buffer box 33 has multiple sets of water holes to buffer the clear water.
[0045] A buffer assembly 4 is provided on the sedimentation chamber 27, which is suitable for buffering the sewage during discharge.
[0046] like Figure 2 and Figures 5-6 As shown, an outlet 34 is provided on the sedimentation chamber 27. A three-way valve 41 is detachably installed on the outlet 34. A straight pipe 42 is provided at the lower end of the three-way valve 41 so that sewage can be discharged quickly when the sewage flow rate is low. Since the straight pipe 42 is located at the lower end, it can form a 90-degree bend with the inlet end of the three-way valve 41, thus having a certain buffering effect during sewage discharge.
[0047] A buffer pipe 43 is provided at the other end of the three-way valve 41. The buffer pipe 43 is equipped with multiple sets of buffer plates 44, which are arranged in an alternating manner. When the sewage flow rate is high, the three-way valve 41 is controlled to connect the buffer pipe 43 to the outlet 34, so that the sewage comes into contact with the multiple sets of buffer plates 44 during sewage discharge to buffer it.
[0048] It should be noted that both ends of the buffer tube 43 have flanges, so that the flanges can be connected to one end of the three-way valve 41 by bolts. After long-term use, when there are too many impurities left inside the buffer tube 43, it can be disassembled and replaced.
[0049] In summary, during use, multiple sets of stirring units are activated, and sewage is simultaneously drawn into the inlet chamber 22 through the inlet pipe 21. The stirring units agitate the sewage to break up impurities. When the inlet chamber 22 is full of sewage, the sewage enters the flocculation chamber 24 through the connecting port 23. At this time, flocculant is added to the flocculation chamber 24, and the stirring units mix the flocculant and sewage. As the sewage gradually fills the flocculation chamber 24, the sewage will circulate up and down repeatedly under the action of the guide tube 241 to achieve better mixing. It then enters the sedimentation chamber 27 through multiple sets of channels 25 for sedimentation, causing sludge and impurities to settle at the bottom of the sedimentation chamber 27. Meanwhile, the clean water flows upward through the treatment box 26 and undergoes secondary sedimentation. The clean water at the top enters the transition box 31 through the clean water tank and clean water outlet 32 and flows into the clean water chamber 28. Finally, the clean water is discharged.
[0050] When discharging sewage, control the three-way valve 41 to connect the direct pipe 42 to the outlet 34 to discharge the sewage. When the sewage flow rate is large, control the three-way valve 41 to connect the buffer pipe 43 to the outlet 34 to buffer the sewage.
[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
