[0039] The following reference Figure 1 and Figure 2 This application describes a wastewater treatment apparatus and filtration system according to some embodiments.

[0040] Example 1

[0041] See Figure 1 As shown, an embodiment of this application provides a wastewater treatment device applied to a filter tank 24. The wastewater treatment device includes: a water storage tank 1, a water supply pipeline 2, a circulation pump 3, a first valve 4, a water receiving tank 5, a first drainage pipeline 6, a drainage distributor 7, a second drainage pipeline 8, a second valve 9, and a discharge box 11; wherein, the water storage tank 1 is connected to the water inlet 241 of the filter tank 24 through the water supply pipeline 2, and the circulation pump 3 and the first valve 4 are both located on the water supply pipeline 2;

[0042] The first drainage pipe 6 and the drainage distributor 7 are both installed in the filter tank 24, and the first drainage pipe 6 is connected to the inside of the filter tank 24 through the drainage distributor 7; the second drainage pipe 8 is installed outside the filter tank 24, and the water receiving tank 5 is connected to the first drainage pipe 6 through the second drainage pipe 8; the filter tank 24 has a discharge port 242, and the second valve 9 is installed in the discharge port 242.

[0043] Based on the structure described above, the working process of this wastewater treatment device is as follows:

[0044] Simultaneously start the circulation pump 3, open the first valve 4 (the first valve 4 can be a normally closed valve) and the second valve 9. Under the positive pressure of the circulation pump 3, water flows into the filter tank 24. Under the action of the circulation pump 3 continuously providing positive pressure water flow, the water flows downward through the gaps between the filter media. The downward water flow carries the filter media downward together. The filter media flow is discharged through the second valve 9. Under the action of the circulation pump 3 continuously providing positive pressure water flow to the filter tank 24, another small part of the water flows upward in the opposite direction through the bottom drain distributor 7, and enters the water storage tank 1 through the first drain pipe 6 to the second drain pipe 8.

[0045] As can be seen, by using the wastewater treatment device provided in this application, the filter media in the filter tank 24 can be discharged directly without having to lay the filter tank 24 down and manually remove the material. The operation is simpler and more convenient, saving time and effort, greatly improving work efficiency, saving manpower, and there are no safety hazards.

[0046] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a third valve 12, which is installed in the filter tank 24. The third valve 12 is a multi-way valve. Its first inlet is connected to the water supply pipeline 2, its second inlet is connected to the first drainage pipeline 6, its first outlet is connected to the water inlet 241 of the filter tank 24, and its second outlet is connected to the second drainage pipeline 8. Therefore, after adjustment of the third valve 12, the first inlet and first outlet of the third valve 12 can... The first outlet of the third valve 12 is connected to the inlet 241 of the filter tank 24, forming an inlet water conveying channel. The water from the water supply pipeline 2 is conveyed to the filter tank 24 through the inlet water conveying channel. The second inlet of the third valve 12 is connected to the second outlet of the third valve 12, forming an outlet water conveying channel. It can be seen that after the adjustment of the third valve 12, the second inlet of the third valve 12 is connected to the second outlet of the third valve 12, and the water discharged from the first drain pipeline 6 is conveyed to the second drain pipeline 8 through the outlet water conveying channel.

[0047] As can be seen from the structure described above, the third valve 12 is an existing water treatment multi-way valve, which can ensure that water flows in from the first inlet end of the water supply pipeline 2 and flows out from the first outlet end into the filter tank 24. It can also ensure that the filtered water flowing out of the first drain pipeline 6 passes through the second inlet end of the third valve 12 and finally flows out from the second outlet end of the third valve 12. It can be seen that the third valve 12 can be used to control the water circuit, and the controllability is stronger.

[0048] Furthermore, preferably, the third valve 12 is a water treatment multi-way control valve in the prior art, which can be communicatively connected to the controller 15 described below and controlled by the controller 15. The third valve 12 can be selected as a P-series softening valve 64502 (F65P), which has three working modes: operating mode, forward washing mode, and backwashing mode. Cleaning of the filter tank 24 can only be achieved in forward washing mode. Of course, the third valve 12 can also be a purely mechanical manual multi-way valve, depending on actual needs.

[0049] It should be noted that the third valve 12 may not be required. That is, the water supply pipeline 2 can be directly connected to the inlet 241 of the filter tank 24 via a connector or directly. When the water supply pipeline 2 is connected to the inlet 241 of the filter tank 24 via a connector, one end of the first drain pipeline 6 extends out of the inlet 241 and the connector, and connects to the external second drain pipeline 8. When the water supply pipeline 2 is directly connected to the inlet 241 of the filter tank 24, one end of the first drain pipeline 6 extends out of the inlet 241 and the water supply pipeline 2, and connects to the external second drain pipeline 8, etc. The specific choice depends on the actual needs.

[0050] In this embodiment, preferably, as follows: Figure 2 As shown, the wastewater treatment device also includes a base sealing ring 13, and the base sealing ring 13 is compressed between the valve base 121 of the third valve 12 and the edge structure of the inlet 241 of the filter tank 24.

[0051] As can be seen from the structure described above, a base sealing ring 13 is provided between the valve base 121 of the third valve 12 and the edge structure of the inlet 241 of the filter tank 24, which can effectively prevent leakage and pressure loss in the filter tank 24, thereby ensuring the unloading function.

[0052] In this embodiment, preferably, as follows: Figure 2 As shown, the wastewater treatment device also includes a drain pipe sealing ring 14, which is sleeved on the outside of the first drain pipe 6 and abuts against the base sealing ring 13.

[0053] As can be seen from the structure described above, a drain pipe sealing ring 14 is provided on the outer periphery of the end of the first drain pipe 6. Combined with the aforementioned base sealing ring 13, a double sealing structure is formed, which can effectively prevent leakage and pressure loss in the filter tank 24, thereby ensuring the unloading function.

[0054] In this embodiment, preferably, as follows: Figure 1 As shown, the first valve 4 is a solenoid valve, the second valve 9 is an electric ball valve, and the third valve 12 is a water treatment multi-way control valve; the wastewater treatment device also includes a controller 15, and the controller 15 is communicatively connected to the first valve 4, the second valve 9 and the third valve 12 respectively.

[0055] As can be seen from the structure described above, by setting the controller 15, the first valve 4, the second valve 9 and the third valve 12 can be automatically controlled, improving the convenience of operation and making the whole control process more time-saving and labor-saving.

[0056] Furthermore, preferably, the first valve 4 is a normally closed solenoid valve, and the second valve 9 is an electric ball valve. Of course, it is not limited to this.

[0057] Furthermore, preferably, the controller 15 is equipped with a discharge button 151 and a control valve button 152. First, press the control valve button 152 to switch the control valve to the forward washing mode (this operation allows the pipeline system to depressurize when the control valve switches between different positions, which can prevent the mixing and water hammer phenomenon generated by the control valve during the position switching process). Then, press the discharge button 151. At this time, the system synchronously starts the circulation pump 3, opens the normally closed solenoid valve and the electric ball valve.

[0058] It should be noted that the first valve 4, the second valve 9, and the third valve 12 can also be non-electric valves, that is, ordinary mechanical valves, which need to be adjusted manually. The specific selection depends on the actual needs, and in this case, the controller 15 is not required.

[0059] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the first inlet end of the third valve 12 is connected to the water supply pipeline 2 via a quick connector 23.

[0060] As can be seen from the structure described above, by setting a quick connector 23 at the connection between the first inlet end of the third valve 12 and the water pipeline 2, quick connection and disassembly can be achieved, which facilitates the initial installation and subsequent maintenance or replacement operations.

[0061] It should be noted that the aforementioned quick connector 23 may not be required. Instead, the first inlet end of the third valve 12 may be connected to the water supply pipeline 2 by welding, gluing, or a combination of flanges and bolts.

[0062] In this embodiment, preferably, as follows: Figure 1 and Figure 2 As shown, the second outlet end of the third valve 12 is connected to the second drain pipe 8 via a quick connector 23.

[0063] As can be seen from the structure described above, by setting a quick connector 23 at the connection between the second outlet end of the third valve 12 and the second drain pipe 8, quick connection and disassembly can be achieved, which facilitates the initial installation and subsequent maintenance or replacement operations.

[0064] It should be noted that the aforementioned quick connector 23 may not be required. Instead, the second outlet end of the third valve 12 may be connected to the second drain pipe 8 by welding, gluing, or a combination of flanges and bolts.

[0065] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a water inlet distributor 16, which is located inside the filter tank 24. The water inlet distributor 16 is cap-shaped and covers the outside of the first drainage pipe 6. It is connected to the water inlet 241 of the filter tank 24. Water transported through the water supply pipe 2 can enter the filter tank 24 through the water inlet distributor 16.

[0066] As described above, the water flowing into the third valve 12 enters the cap-shaped water distributor 16, and then, after being evenly distributed by the distributor, enters the filter tank 24. Under the continuous positive pressure of the circulating pump 3, the water flows downward through the gaps between the filter media. At this time, the third valve 12 is open, and the downward-flowing water carries the filter media downward along with it. The filter media is then discharged into the receiving box through the third valve 12 and the discharge pipe 10 described below (e.g., ...). Figure 1 (As indicated by the double-lined arrow).

[0067] Furthermore, preferably, the water inlet distributor 16 can be a mushroom-head water distributor in the prior art, but of course, it is not limited to this.

[0068] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a support base 17, and the second valve 9 is placed on the support base 17.

[0069] As can be seen from the structure described above, adding a support seat 17 below the second valve 9, such as an electric ball valve, increases the strength of the flange structure at the discharge port 242 of the filter tank 24 and improves the stability of the pipeline at that point during discharge, effectively preventing vibration.

[0070] In this embodiment, preferably, as follows: Figure 1As shown, the wastewater treatment device also includes a liquid level sensor 18, which is installed in the water storage tank 1 and is used to detect the liquid level in the water storage tank 1. Preferably, the liquid level sensor 18 is communicatively connected to the controller 15.

[0071] As can be seen from the structure described above, during the periodic cyclic use of this device, when the water level in the water storage tank 1 is lower than the set low liquid level height value, the liquid level sensor 18 transmits a low liquid level alarm signal to the controller 15. At this time, the controller 15 automatically suspends the operation of the system until water is added to the water storage tank 1. After that, the low liquid level alarm signal of the controller 15 is eliminated, and the controller 15 will automatically resume the operable state.

[0072] It should be noted that when the device does not include the controller 15, the result detected by the liquid level sensor 18 can be viewed manually, or the liquid level sensor 18 with alarm function can be used directly.

[0073] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a bottom valve 19, which is installed inside the water supply pipeline 2 at one end of the water storage tank 1.

[0074] As can be seen from the structure described above, a bottom valve 19 is installed inside one end of the water supply pipeline 2 located in the water storage tank 1 to prevent water backflow.

[0075] Furthermore, preferably, the bottom valve 19 can be a one-way valve.

[0076] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a filter 20, which is installed inside and / or outside one end of the water supply pipeline 2 located in the water storage tank 1.

[0077] As can be seen from the structure described above, the water entering the water supply pipe 2 must first pass through the filter 20 to avoid introducing impurities.

[0078] In this embodiment, preferably, as follows: Figure 1 As shown, the discharge port 242 of the filter tank 24 is provided with a first flange 21, the second valve 9 is provided with a second flange 22, and the first flange 21 and the second flange 22 are detachably connected by fastening components, and a sealing ring is provided between the first flange 21 and the second flange 22.

[0079] As can be seen from the structure described above, the second valve 9 is assembled with the discharge port 242 of the filter tank 24 by connecting the first flange 21 and the second flange 22 and fastening them with fastening components such as bolts or screws, which improves the convenience of operation. Moreover, it is a detachable connection structure, which facilitates later maintenance or replacement operations. In addition, a sealing ring is set between the first flange 21 and the second flange 22 for sealing, which can effectively prevent filter material leakage.

[0080] In this embodiment, preferably, as follows: Figure 1 As shown, the wastewater treatment device also includes a discharge pipe 10 and a discharge box 11, and the discharge box 11 is connected to the outlet end of the second valve 9 through the discharge pipe 10.

[0081] As can be seen from the structure described above, the filter material discharged from the discharge port 242 of the filter tank 24 is discharged into the discharge box 11 through the discharge pipe 10, so as to avoid environmental pollution and ensure the cleanliness of the workplace.

[0082] It should be noted that the aforementioned unloading pipe 10 and unloading box 11 may not be required. Existing containers such as basins may be placed below the unloading port 242.

[0083] In this embodiment, preferably, as follows: Figure 1 As shown, the first drain pipe 6 extends along the height direction of the filter tank 24 and extends from the top of the filter tank 24 to the bottom of the filter tank 24, and the drain distributor 7 is provided at the bottom end of the first drain pipe 6; an inlet 241 is formed at the top of the filter tank 24 along its height direction; and a discharge port 242 is formed on the side wall of the filter tank 24 near its bottom along the height direction of the filter tank 24.

[0084] As described above, the inlet 241 is located at the top of the filter tank 24, the outlet 242 is located on the side wall of the filter tank 24 near its bottom, and the first drain pipe 6 extends from the top to the bottom of the filter tank 24, thus allowing all the filter media inside the filter tank 24 to be discharged. Of course, this is not the only option; the positions of the inlet 241, outlet 242, and the orientation of the first drain pipe 6 can be designed according to actual needs.

[0085] In this embodiment, preferably, as follows: Figure 1 As shown, the first drain pipe 6 is located on the center line of the filter tank 24 along its height direction, which makes the filter media distribution on the outer periphery of the first drain pipe 6 more uniform and helps to ensure the uniformity of filter media discharge from all places.

[0086] In this embodiment, preferably, as follows: Figure 1 As shown, the circulating pump 3 is positioned relative to the first valve 4 and close to the water storage tank 1.

[0087] As can be seen from the structure described above, the area on one side of the water storage tank 1 is fully utilized, avoiding interference with other components. Of course, this is not the only option; the circulation pump 3 can also be located behind the first valve 4, away from the water storage tank 1, etc., depending on the specific design requirements.

[0088] In summary, the detailed working process of the filtration system provided in this application is as follows:

[0089] The controller 15 is equipped with a discharge button 151 and a control valve button 152. First, press the control valve button 152 to switch the control valve to the forward washing mode (this operation allows the pipeline system to depressurize when the control valve switches between different positions, which can prevent the mixing and water hammer phenomenon generated by the control valve during the position switching process). Then, press the discharge button 151. At this time, the system synchronously starts the circulation pump 3, opens the first valve 4 (e.g., a normally closed solenoid valve) and the second valve 9 (e.g., an electric ball valve).

[0090] Under the positive pressure of the circulating pump 3, the water flows through the filter 20 and then enters the circulating pump 3 through the bottom valve 19. After the positive pressure is output, the water flows through the first valve 4, such as a normally closed solenoid valve, or the quick connector 23, and then enters the third valve 12.

[0091] After entering the third valve 12, the water flows into the cap-shaped water distributor 16, and then, after being evenly distributed by the distributor, enters the filter tank 24. Under the continuous positive pressure of the circulating pump 3, the water flows downward through the gaps between the filter media. At this time, the second valve 9, for example, an electric ball valve, is open. The downward-flowing water carries the filter media downward along with it. The filter media is then discharged into the receiving box (e.g., via the third valve 12, for example, an electric ball valve, and the discharge pipe 10 described below) through the third valve 12 and the discharge pipe 10 described below. Figure 1 (As indicated by the double-lined arrow in the middle);

[0092] Under the action of the circulating pump 3 continuously supplying positive pressure water flow to the filter tank 24, part of the water flow carries the filter media through the second valve 9, such as an electric ball valve and the discharge pipe 10, and discharges the filter media into the receiving box; another small part of the water flows upward in the opposite direction through the bottom drain distributor 7, flows out through the first drain pipe 6 to the third valve 12, and enters the water receiving tank 5 through the quick connector 23 and the second drain pipe 8.

[0093] By observing the discharge status of the discharge pipe 10, when the filter material in the filter tank 24 is completely discharged, press the discharge button 151 on the controller 15 to close the discharge operation, and at the same time press the control valve button 152 on the controller 15 to switch the control valve to the operating mode.

[0094] During the periodic cyclical use of this device, when the water level in the water storage tank 1 is lower than the set low liquid level height value, the liquid level sensor 18 transmits a low liquid level alarm signal to the controller 15. At this time, the controller 15 automatically suspends the operation of the system until water is added to the water storage tank 1. After that, the low liquid level alarm signal of the controller 15 is eliminated, and the controller 15 will automatically resume the operable state.

[0095] As can be seen, by using the wastewater treatment device provided in this application, the filter media in the filter tank 24 can be discharged directly without having to lay the filter tank 24 down and manually remove the material.
