Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and more specifically, it relates to a water-saving device for engineering construction. Background Technology

[0002] Currently, water consumption is very high at environmental engineering construction sites. Much of this water is discharged directly after use, which not only causes significant waste but also has a certain impact on the surrounding environment. Furthermore, due to the long construction period, a lot of rainwater can accumulate at the construction site. Most of this rainwater is not collected, resulting in low utilization and significant waste of water resources.

[0003] Furthermore, after treating rainwater or wastewater, residue inside the water will remain on the surface of the filter screen. Since most of the filter screens of water-saving devices are located inside the device, they are not convenient to clean, and long-term use can easily lead to clogging. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a water-saving device for engineering construction, which has the following beneficial effects:

[0017] 1. By setting up a filter screen, filter box, pad, and V-shaped plate, the user can pour wastewater into the housing through the inlet pipe.

[0029] Please see Figure 1-5 A water-saving device for engineering construction includes a housing 1. Filter screens 2 are fixedly installed on the inner wall of the housing 1 on both sides. The filter screens 2 are inclined. A filter box 3 is movably installed in the middle of the two filter screens 2. A pad 4 is correspondingly installed on the inner wall of the housing 1. The bottom of the filter box 3 is in contact with the upper end of the pad 4. A connecting rod 5 is installed on the upper surface of the filter box 3 on both the front and rear sides. A V-shaped plate 6 is fixedly installed in the middle of the connecting rod 5. A cover 7 is installed at the upper end of the housing 1. A water inlet pipe 8 is installed at the upper end of the cover 7. The water inlet pipe 8 is located directly above the V-shaped plate 6.

[0030] In this embodiment, a coarse filter plate 9 is provided inside the water inlet pipe 8. Mounting cylinders 10 are fixedly provided on the upper end face and both sides of the cover 7. Mounting posts 11 are provided on the upper end face and both sides of the housing 1. The mounting posts 11 are all located inside the mounting cylinders 10. Pins 12 are slidably provided on the outer wall of the mounting cylinders 10. Insertion holes 13 are correspondingly opened on the mounting posts 11. One end of the pins 12 is located inside the insertion holes 13. The other end of the pins 12 is provided with a pull block 14. A connecting spring 15 is provided between the pull block 14 and the mounting cylinder 10. A funnel 16 is fixedly provided at the upper end of the water inlet pipe 8. A protective plate 23 is fixedly provided at the bottom of the filter screen 2. Both sides of the filter box 3 are in contact with the protective plate 23. A water leakage hole 24 is opened at the bottom of the filter box 3.

[0031] More specifically, the user can pour wastewater into the housing 1 through the inlet pipe 8. At this time, the coarse filter plate 9 inside the inlet pipe 8 will filter out large particles of impurities in the wastewater. After the wastewater enters the housing 1, the V-shaped plate 6 will separate the falling wastewater so that it comes into contact with the filter screen 2, thereby leaving other impurities in the wastewater at the top of the filter screen 2. Since the filter screen 2 is set at an angle, the impurities will gradually fall into the filter box 3. After use, the pull block 14 can be pulled to disengage one end of the pin 12 from the insertion hole 13. At this time, the mounting cylinder 10 and the mounting column 11 can be disassembled to separate the cover 7 and the housing 1, making it convenient to clean the coarse filter plate 9. At this time, the filter box 3 can also be removed from the inside of the housing 1 for convenient centralized cleaning of the impurities inside.

[0032] Please see Figures 1-3As an embodiment for rinsing the filter screen 2: the upper end of the filter screen 2 is provided with a spray pipe 17, the bottom of the spray pipe 17 is provided with a spray head 18, the outer wall of the spray pipe 17 is provided with a water inlet pipe 19, the outer wall of the housing 1 is fixedly provided with a cleaning pipe 20 at the bottom, the other end of the cleaning pipe 20 is connected to the water inlet pipe 19, and the cleaning pipe 20 is provided with a water pump 21.

[0033] Specifically, the user can turn on the water pump 21 to allow the treated water to enter the spray pipe 17 through the water inlet pipe 19 and the cleaning pipe 20, and spray it out through the spray head 18 to rinse the filter screen 2 inside the housing 1, so that the impurities on the top can quickly enter the filter box 3 for centralized treatment.

[0034] Please refer to Figure 3 As a further embodiment for discharging the treated water: a drain pipe 22 is fixedly provided on the outer wall of the housing 1 at the bottom, and an inclined slope is provided on the inner wall of the housing 1 at the bottom. The drain pipe 22 is located at the lower end of the inclined slope, and a valve is provided on the drain pipe 22.

[0035] Specifically, the valve can be opened to remove the treated water from inside the shell 1 for reuse, thus saving water resources.

[0036] In summary, when using the entire device: the user can pour wastewater into the housing 1 through the inlet pipe 8. The coarse filter plate 9 inside the inlet pipe 8 will then filter out large particles of impurities in the wastewater. After the wastewater enters the housing 1, the V-shaped plate 6 will separate the falling wastewater, allowing it to contact the filter screen 2. This will trap other impurities on the upper part of the filter screen 2. Because the filter screen 2 is tilted, the impurities will gradually fall into the filter box 3. After use, the pull block 14 can be pulled to disengage one end of the pin 12 from the socket 13. Then the mounting cylinder 10 and mounting column 11 can be disassembled to separate the cover 7 and the housing 1, making it easier to clean the coarse filter plate 9. At this time, the filter box 3 can also be removed from the inside of the housing 1 for easy centralized cleaning of the impurities inside. The user can also turn on the water pump 21 to allow the treated water to enter the spray pipe 17 through the water inlet pipe 19 and the cleaning pipe 20, and spray it out through the spray head 18 to rinse the filter screen 2 inside the housing 1, so that the impurities on the top can quickly enter the filter box 3 for subsequent centralized treatment.
