Abstract
Description
Technical Field
[0001] This utility model relates to the field of tap water treatment technology, and more specifically, to a tap water flocculation separator. Background Technology
[0002] Water flocculants work by adding coagulants to raw water, causing colloidal particles to destabilize, collide, and aggregate into visible "flocculations." These flocs are then trapped by a filter screen, separating them from the clean water to produce treated water with low turbidity, low color, and low microbial count. The filter screen is typically equipped with rotating brushes or reciprocating scrapers, which are periodically cleaned without shutting down the system, scraping off the trapped flocs.
[0003] The drawback of existing equipment is that the brush plate can only mechanically clean the surface of the filter screen, and the flocculent material always accumulates on the water-facing side of the filter screen and cannot actually leave the filtration zone. Over time, the amount of flocculent material increases, affecting the filtration effect of the filter screen, requiring frequent maintenance, high frequency of manual disassembly and cleaning, and increasing costs. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.
[0031] like Figure 1 and Figure 2 As shown, the tap water flocculant separator provided in Embodiment 1 of this application includes a base 1, on which a mixing tank 2, a filter tank 3, and a chemical storage tank 4 are disposed. The top plate of the mixing tank 2 is provided with a first water inlet 22 and a chemical inlet. The first water inlet 22 is used to connect to a tap water pipe. The chemical storage tank 4 is disposed on the top plate of the mixing tank 2, and the chemical inlet is used to connect to the chemical storage tank 4. The bottom plate of the mixing tank 2 is provided with a first water outlet 25, and a water pump 26 is disposed on the first water outlet 25. A stirring assembly is disposed inside the mixing tank 2. The top plate of the filter tank 3 is provided with a second water inlet 39, and the output end of the water pump 26 is connected to a connecting pipe 5. The filter box 3 has a second inlet 39, a second outlet 34 and a third outlet 37 on its bottom plate, and an annular filter screen 32 inside the filter box 3. The two ends of the filter screen 32 are connected to the top plate and the bottom plate of the filter box 3, respectively. The second inlet 39 and the third outlet 37 are located within the space enclosed by the filter screen 32. The second outlet 34 is located between the filter screen 32 and the body of the filter box 3. The filter box 3 has a cleaning component inside the filter screen 32 to clean it. The second outlet 34 is equipped with a first valve 35, and the third outlet 37 is equipped with a second valve 36.
[0032] The cleaning component cleans the annular filter screen 32 to prevent flocculent material from accumulating on the water-facing side of the screen. The cleaned flocculent material falls at the bottom of the area enclosed by the annular filter screen 32. The second outlet 34 is located on the outside of the filter screen and discharges clean water during normal filtration. The third outlet 37 is located on the inside of the filter screen and discharges flocculent material directly after the clean water is discharged, thoroughly separating impurities from the filtration area, preventing flocculent material accumulation, and reducing the frequency of maintenance.
[0033] like Figure 3 and Figure 4 As shown, the mixing component includes a first rotating shaft 23 rotatably connected to the top plate of the mixing tank 2. A first motor 21 is provided on the top plate of the mixing tank 2. The output end of the first motor 21 is connected to the first rotating shaft 23. Multiple sets of stirring blades 24 are provided on the first rotating shaft 23 to achieve full mixing of coagulant and raw water, promote rapid destabilization of colloidal particles and aggregation into larger flocs, facilitate subsequent filtration, and improve the quality of effluent.
[0034] like Figure 10 and 11 As shown, the cleaning assembly includes a second rotating shaft 33 rotatably connected to the top plate of the filter box 3. A second motor 31 is installed on the top plate of the filter box 3. The output end of the second motor 31 is connected to the second rotating shaft 33. A cleaning plate 331 extending in the same direction as the second rotating shaft 33 is installed on the second rotating shaft 33. A cleaning brush 332 is installed on the edge of the cleaning plate 331. The cleaning brush 332 contacts the filter screen 32. The axis of the annular filter screen 32 coincides with the axis of the filter box 3. The second motor 31 drives the second rotating shaft 33 to rotate the cleaning plate 331 and the cleaning brush 332, actively cleaning the water-facing surface of the filter screen. Through mechanical wiping, flocculents are peeled off from the surface of the filter screen and, under gravity, enter the collection area, preventing flocculents from accumulating and clogging the filter screen pores, maintaining the filtration performance of the filter screen 32, and extending the service life of the filter screen.
[0035] like Figure 5 , Figure 6 and Figure 7 As shown, a partition 44 is provided inside the storage tank 4, dividing the interior of the storage tank 4 into an inlet chamber 45 and a storage chamber. The inlet chamber 45 is located in contact with the bottom of the storage tank 4, and a dosing port 46 is provided at the top of the storage tank 4. A dosing port 49 is provided at the bottom of the inlet chamber 45, and the dosing port 49 is connected to the inlet port. A connecting port 47 is formed on the partition 44, and a stop 48 is slidably installed in the connecting port 47. The stop 48 is used to block the connecting port 47 or the dosing port 49. A telescopic rod 481 is connected to one side of the stop 48 along the sliding direction, and the telescopic rod 481 is used to drive the stop 48 to slide. The connecting port 47 and the stop 48 cooperate to control the amount and timing of coagulant dosing by sliding the stop 48, so as to achieve precise dosing, improve the coagulation effect and avoid waste of the agent. Figure 2As shown, the telescopic rod 481 is driven by a drive device 41, which is located on the outside of the medicine storage tank 4. In actual use, as... Figure 8 As shown, the baffle 48 blocks the medicine outlet 49, and the medicine enters the medicine inlet chamber 45 through the connecting port 47, as... Figure 9 As shown, once the inlet chamber 45 is full, the stop block 48 slides to block the connecting port 47, and the medicine enters the mixing tank 2 from the inlet through the outlet port 49. Since the space capacity of the inlet chamber 45 remains constant, the amount of medicine added each time can be kept constant.
[0036] like Figure 6 As shown, a sealing plug 42 is provided on the dosing port 46, and a sealing ring is provided between the sealing plug 42 and the dosing port 46. A pull handle 43 is provided on the side of the sealing plug 42 opposite to the dosing port 46 to prevent external impurities from entering the storage tank 4 and contaminating the coagulant, thus ensuring the purity of the agent and the treatment effect. The handle 43 is designed for easy manual operation, making it convenient to open and close the dosing port 46, thereby improving the convenience and safety of the dosing operation.
[0037] like Figure 4 As shown, the bottom surface of the mixing tank 2 is provided with a first inclined surface 27, the inclined direction of the first inclined surface 27 facing the first outlet 25; the bottom surface of the filter screen 32 is provided with a second inclined surface 38, the inclined direction of the second inclined surface 38 facing the second outlet 34. The first inclined surface 27 guides the mixed liquid to converge towards the first outlet 25, ensuring that the mixed liquid can be fully extracted by the water pump 26, avoiding local stagnation of the mixed liquid, and improving the utilization rate of the mixing tank 2; the second inclined surface 38 inside the filter screen 32 causes the flocculent to slide down towards the second outlet 34, which is convenient for collecting and discharging the flocculent, while preventing the flocculent from accumulating at the bottom of the filter screen 32, reducing cleaning dead corners, and improving the cleanliness of the inside of the filter tank 3.
[0038] In this embodiment, the edge of the inner bottom surface of the filter screen 32 extends toward the filter screen 32 to form a storage area, which provides a temporary storage space for the flocculent material swept down by the cleaning brush 332, and retains some liquid, which is conducive to the subsequent centralized discharge of flocculent material and prevents the flocculent material from re-entering the filtration area and affecting the filtration effect.
[0039] The first valve 35 is a first electric valve 35, and the second valve 36 is a second electric valve 36, enabling remote automatic control of the second outlet 34 and the third outlet 37. Compared to manual valves, electric valves can be integrated with automated control systems, automatically adjusting their opening and closing based on parameters such as filtration pressure and time, achieving automated switching of filtration processes, automatically cleaning the filter screen 32, and automatically discharging the wastewater.
[0040] The working process of the tap water flocculant separator provided in Embodiment 1 of this application is as follows:
[0041] Preparation stage for adding chemicals: Add an appropriate amount of coagulant to the storage tank 4, and then use the pull handle 43 to tightly close the sealing plug 42 to prevent external impurities from entering the storage tank 4 and contaminating the coagulant.
[0042] During the operation of the mixing tank: tap water flows into the mixing tank 2 through the first inlet 22. At the same time, the coagulant in the storage tank 4 is quantitatively stored in the storage chamber through the connecting port 47 and enters the mixing tank 2 through the outlet 49 and the inlet 46. The first motor 21 is started, driving the first rotating shaft 23 to rotate, so that the multiple sets of stirring blades 24 on the rotating shaft can fully stir the raw water and coagulant in the mixing tank 2, causing the colloidal particles to quickly destabilize and aggregate into flocs. The stirred mixture in the mixing tank 2 converges to the first outlet 25 along the first inclined surface 27 set on the bottom of the mixing tank 2.
[0043] Filtration stage: The water pump 26 draws the mixture in the mixing tank 2 out of the first outlet 25 and transports it to the second inlet 39 of the filter tank 3 through the connecting pipe 5. After the mixture enters the filter tank 3, it flows in the space enclosed by the filter screen 32. The flocculent material is intercepted by the filter screen 32, while the clean water passes through the filter screen 32 and flows along the channel between the filter screen 32 and the filter tank 3 to the second outlet 34, and is finally discharged from the second outlet 34. The second outlet 34 is equipped with a first electric valve 35. During normal filtration, the first electric valve 35 is opened to discharge clean water. During the filtration process, the cleaning component in the filter screen 32 starts to work. The second motor 31 drives the second rotating shaft 33 to rotate, which drives the cleaning plate 331 and cleaning brush 332 on the rotating shaft to rotate. The cleaning brush 332 is close to the water-facing surface of the filter screen 32 and peels the flocculent material off the surface of the filter screen. The peeled flocculent material falls to the bottom of the area enclosed by the annular filter screen 32 under the action of gravity. The bottom surface of the filter screen 32 is provided with a second inclined surface 38, which is inclined towards the third outlet 37. The second inclined surface 38 causes the flocculent material to slide down to the third outlet 37.
[0044] Sludge removal stage: After the filtration cycle is completed, the flocculent material inside the filter screen 32 needs to be discharged. The first electric valve 35 is closed and the second electric valve 36 is opened. Under the action of gravity, the flocculent mixed water has accumulated in the collection area. The flocculent material is discharged directly from the third outlet 37, which completely separates impurities from the filtration area, avoids the accumulation of flocculent material, and reduces the frequency of maintenance.
[0045] The above are merely preferred embodiments of this application and are 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.
