Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to an intelligent control secondary pressurized water supply energy-saving device. Background Technology

[0002] Nowadays, some buildings are very tall, and it is difficult to transmit water to them with a single water supply. Therefore, a secondary pressurized water supply device is needed. It is a new generation of intelligent water supply equipment that achieves automatic flow stabilization and balance by controlling the flow and pressure of tap water inflow and the flow and pressure of water usage in both directions, so that the water pressure on high floors can be guaranteed.

[0003] Most existing secondary pressurized water supply systems draw water from a transition tank and then transmit it directly to each household, lacking filtration of large particulate impurities, resulting in unclean water sources. Utility Model Content

[0004] This utility model discloses an intelligent control secondary pressurized water supply energy-saving device, which mainly solves the problem that traditional secondary pressurized water supply devices lack filtration to filter large particulate impurities.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides an intelligent control secondary pressurized water supply energy-saving device, including a box, a protective cavity in the box, a water supply pipe in the protective cavity, one end of the water supply pipe being a water inlet and the other end being a water outlet, and both ends of the water supply pipe passing through the box.

[0007] Along the direction from the water inlet to the water outlet, the water supply pipe is sequentially connected to a high-pressure water pump and a filter assembly. A drain pipe is provided between the filter assembly and the water inlet of the water supply pipe. A cleaning solenoid valve is provided on the drain pipe. A pressure sensor is provided on the water supply pipe at the position corresponding to the drain pipe.

[0008] The filter assembly includes a filter housing and a mounting cover. The filter housing has a filter chamber, and the filter chamber has multiple filter screens spaced apart. The mounting cover installs the multiple filter screens into the filter chamber of the filter housing. Along the direction from the water inlet to the water outlet, the mesh size of the multiple filter screens gradually decreases, and the spacing between the multiple filter screens gradually decreases.

[0009] In one embodiment, a hollow support ring is provided between adjacent filter screens, and the length of the plurality of support rings gradually increases along the direction from the water inlet to the water outlet.

[0010] In one embodiment, the housing is further provided with a reverse cleaning assembly, which includes a reverse cleaning pipe. One end of the reverse cleaning pipe is an inlet end, and the other end is an outlet end. The inlet end of the reverse cleaning pipe is connected to the water supply pipe between the filter assembly and the sewage pipe, and the outlet end of the reverse cleaning pipe is connected to the water supply pipe between the outlet end and the filter assembly. The middle end of the reverse cleaning pipe is located outside the housing, and a detachable external filter element is installed at the middle end of the reverse cleaning pipe. A first solenoid valve is provided between the pressure sensor and the inlet end of the reverse cleaning pipe on the water supply pipe, a second solenoid valve is provided at the inlet end of the reverse cleaning pipe, and a third solenoid valve is provided between the outlet end of the water supply pipe and the outlet end of the reverse cleaning pipe.

[0011] In one embodiment, the first solenoid valve, the second solenoid valve, and the third solenoid valve are all disposed in the protective cavity.

[0012] In one embodiment, the external filter includes an external filter sleeve and a cover. The external filter sleeve has a cleaning chamber, and the cleaning chamber has a plurality of cleaning screens spaced apart. The cover installs the plurality of cleaning screens into the cleaning chamber of the external filter sleeve. Along the direction from the inlet end to the outlet end of the reverse cleaning pipe, the mesh size of the plurality of cleaning screens is gradually reduced, and the spacing between the plurality of cleaning screens is gradually reduced.

[0013] In one embodiment, a hollow spacer ring is provided between adjacent cleaning filters, and the length of the plurality of spacer rings gradually increases along the direction from the inlet end to the outlet end of the reverse cleaning pipe.

[0014] In one embodiment, the two ends of the external filter are mounted on the reverse cleaning pipe via a disassembly and assembly component. The disassembly and assembly component includes connecting pipes disposed at both ends of the external filter. A first threaded sleeve is disposed on the connecting pipe. A second threaded sleeve is disposed on the reverse cleaning pipe at a position corresponding to the first threaded sleeve and cooperating with the first threaded sleeve. The first threaded sleeve and the second threaded sleeve are threadedly connected, and a sealing ring is disposed between the first threaded sleeve and the second threaded sleeve.

[0015] In one embodiment, the housing is provided with an inspection port communicating with the protective cavity, and the inspection port is provided with a detachable inspection door.

[0016] The advantages or beneficial effects of the above technical solution include at least the following: by installing a high-pressure water pump and a filter assembly in the water supply pipe, the high-pressure water pump can draw water from the storage tank on the upper floors to supply water to users on the upper floors. With multiple filter screens in the filter assembly, impurities of different particle sizes can be isolated in filter screens with different mesh sizes, so that impurities of different particle sizes can be isolated in corresponding intervals, thereby filtering the water source in the secondary water supply to prevent the water source from being unclean. At the same time, a drain pipe and a pressure sensor are installed on the water supply pipe, and a cleaning solenoid valve is installed on the drain pipe. This allows staff to determine whether to clean the filter assembly by using the water pressure sensed by the pressure sensor. When cleaning the filter assembly, simply opening the cleaning solenoid valve allows the water pressure drawn in by the high-pressure water pump to impact the impurities on the filter assembly, so that the impurities and water are discharged together through the drain pipe, thereby ensuring the filtration effect of the filter assembly.

[0039] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0040] See Figures 1 to 3 The present invention provides an intelligent control secondary pressurized water supply energy-saving device, including a housing 1, a protective cavity 11 in the housing 1, a water supply pipe 2 in the protective cavity 11, one end of the water supply pipe 2 is a water inlet 21, the other end is a water outlet 22, and both ends of the water supply pipe 2 pass through the housing 1.

[0041] Along the direction from the inlet end 21 to the outlet end 22, the water supply pipe 2 is connected in sequence to the high-pressure water pump 3 and the filter assembly 4. A drain pipe 5 is provided between the inlet end 21 and the filter assembly 4 of the water supply pipe 2. A cleaning solenoid valve 6 is provided on the drain pipe 5. A pressure sensor 7 is provided on the water supply pipe 2 at the position corresponding to the drain pipe 5.

[0042] The filter assembly 4 includes a filter housing 41 and a mounting cover 42. The filter housing 41 is provided with a filter chamber 411, and the filter chamber 411 is provided with a plurality of filter screens 43 spaced apart. The mounting cover 42 installs the plurality of filter screens 43 into the filter chamber 411 of the filter housing 41. Along the direction from the water inlet end 21 to the water outlet end 22, the mesh size of the plurality of filter screens 43 is gradually reduced, and the spacing between the plurality of filter screens 43 is gradually reduced.

[0043] With the above structure, a high-pressure water pump 3 and a filter assembly 4 are installed in the water supply pipe 2. The high-pressure water pump 3 can draw water from the storage tank on the upper floors to supply water to users on the upper floors. With multiple filter screens 43 in the filter assembly 4, impurities of different particle sizes can be isolated in filter screens 43 with different mesh sizes. This allows impurities of different particle sizes to be isolated in corresponding intervals, thereby filtering the water source in the secondary water supply to prevent the water source from being unclean. At the same time, a drain pipe 5 and a pressure sensor 7 are installed on the water supply pipe 2. A cleaning solenoid valve 6 is installed on the drain pipe 5, which allows staff to determine whether to clean the filter assembly 4 by using the water pressure sensed by the pressure sensor 7. When cleaning the filter assembly 4, simply open the cleaning solenoid valve 6, and the water pressure drawn in by the high-pressure water pump 3 will impact the impurities on the filter assembly 4, so that the impurities and water are discharged together through the drain pipe 5, thus ensuring the filtration effect of the filter assembly 4.

[0044] In one embodiment, see Figure 3Hollow support rings 44 are provided between adjacent filter screens 43, and the length of multiple support rings 44 gradually increases along the direction from the water inlet end 21 to the water outlet end 22. In practical applications, the support rings 44 can separate adjacent filter screens 43, creating gaps between them. The length of the support rings 44 can be adjusted to create different gap distances, thus adapting to the filtration space for different particulate impurities.

[0045] In one embodiment, see Figure 2 and Figure 4 The housing 1 is also equipped with a reverse cleaning assembly 8, which includes a reverse cleaning pipe 81. One end of the reverse cleaning pipe 81 is an inlet end and the other end is an outlet end. The inlet end of the reverse cleaning pipe 81 is connected to the water supply pipe 2 between the filter assembly 4 and the sewage pipe 5. The outlet end of the reverse cleaning pipe 81 is connected to the water supply pipe 2 between the outlet end 22 and the filter assembly 4. The middle end of the reverse cleaning pipe 81 is located outside the housing 1. A detachable external filter element 82 is installed at the middle end of the reverse cleaning pipe 81. A first solenoid valve 83 is provided between the pressure sensor 7 and the inlet end of the reverse cleaning pipe 81 on the water supply pipe 2. A second solenoid valve 84 is provided at the inlet end of the reverse cleaning pipe 81. A third solenoid valve 85 is provided between the outlet end 22 and the outlet end of the reverse cleaning pipe 81 on the water supply pipe 2. In practical applications, with the configuration of the reverse cleaning pipe 81, external filter element 82, first solenoid valve 83, second solenoid valve 84, and third solenoid valve 85, when the filter assembly 4 needs to be cleaned, by closing the first solenoid valve 83 and opening the second solenoid valve 84 and the third solenoid valve 85, the outlet end 22 can be closed, and the water at the inlet end 21 can enter from the other end of the filter assembly 4 through the reverse cleaning pipe 81. This allows the impurities filtered in the filter assembly 4 to be backwashed out, and the flushing water can be discharged through the drain pipe 5, thereby increasing the service life of the filter assembly 4. The external filter element 82 installed in the reverse cleaning pipe 81 can filter the water entering the reverse cleaning pipe 81 to ensure the cleanliness of the water when the reverse cleaning pipe 81 cleans the filter assembly 4, so as to avoid contaminating the water at that location, and facilitate timely cleaning of the external filter element 82, thereby preventing the need to frequently disassemble the housing 1.

[0046] The first solenoid valve 83, the second solenoid valve 84, and the third solenoid valve 85 are all housed in the protective cavity 11. In practical applications, housing the first solenoid valve 83, the second solenoid valve 84, and the third solenoid valve 85 in the protective cavity 11 can protect these three valves.

[0047] The external filter element 82 includes an external filter sleeve 821 and a cover 822. The external filter sleeve 821 has a cleaning chamber 823 containing multiple spaced-apart cleaning screens 824. The cover 822 houses the multiple cleaning screens 824 within the cleaning chamber 823 of the external filter sleeve 821. Along the direction from the inlet to the outlet of the reverse cleaning pipe 81, the mesh size of the multiple cleaning screens 824 gradually decreases, as does the spacing between them. In practical applications, the multiple cleaning screens 824 effectively isolate impurities of different particle sizes within the different mesh sizes of the cleaning screens 824, ensuring that impurities of different sizes are isolated in their respective intervals. This filters the water used for cleaning, preventing secondary contamination of the clean water in the water supply pipe 2.

[0048] Hollow spacer rings 825 are provided between adjacent cleaning filter screens 824. The lengths of the multiple spacer rings 825 gradually increase along the direction from the inlet to the outlet of the reverse cleaning pipe 81. In practical applications, the spacer rings 825 separate adjacent cleaning filter screens 824, creating gaps between them. The varying lengths of the cleaning filter screens 824 allow for different gap distances, thus accommodating the filtration of different particulate impurities.

[0049] The two ends of the external filter element 82 are mounted on the reverse cleaning pipe 81 via a disassembly / assembly component 86. The disassembly / assembly component 86 includes connecting pipes 861 located at both ends of the external filter element 82. A first threaded sleeve 862 is provided on the connecting pipe 861, and a second threaded sleeve 863 is provided on the reverse cleaning pipe 81 at a position corresponding to the first threaded sleeve 862, cooperating with the first threaded sleeve 862. The first threaded sleeve 862 and the second threaded sleeve 863 are threadedly connected, and a sealing ring 864 is provided between the first threaded sleeve 862 and the second threaded sleeve 863. In practical applications, the threaded connection between the first threaded sleeve 862 and the second threaded sleeve 863 of the disassembly / assembly component 86 facilitates quick and easy disassembly and installation of the external filter element 82, enabling timely cleaning of impurities within the external filter element 82. Furthermore, the sealing ring 864 enhances the sealing effect between the first threaded sleeve 862 and the second threaded sleeve 863.

[0050] In one embodiment, see Figure 1 The housing 1 is provided with an inspection port 12 that communicates with the protective cavity 11, and the inspection port 12 is provided with a detachable inspection door 13. In practical applications, the inspection port 12 and the inspection door 13 facilitate the access to the water supply pipe 2, high-pressure water pump 3, filter assembly 4, cleaning solenoid valve 6, pressure sensor 7, first solenoid valve 83, second solenoid valve 84 and third solenoid valve 85 in the protective cavity 11.
