Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a water supply and drainage filtration device for building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings. During the construction process, it is usually necessary to drain the construction site. Currently, the drainage method used is to connect the drainage pipe to a drainage filtration device, which uses the filter screen in the drainage filtration device to filter out harmful substances such as mud, sand, and heavy metals from the sewage.

[0003] However, after the drainage device has been used for a long time, the impurities left on the filter screen need to be cleaned manually on a regular basis. This operation requires the filter screen to be removed from the drainage device by hand to complete the cleaning, which has the disadvantages of inconvenience and slow cleaning. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a water supply and drainage filtration device for building construction, so as to solve the technical problems of inconvenient operation and slow cleaning when cleaning impurities in the existing drainage devices in the background art.

[0005] The present invention provides a water supply and drainage filtration device for building construction, including a sewage discharge component and a filter screen disposed in a housing, wherein the housing is used to connect to a drainage pipe;

[0006] The filter screen has multiple outer edge portions, each of which is connected to each inner wall of the housing, and the relative height of each outer edge portion extends toward the interior of the housing from high to low, so as to form an impurity collection area with a size that varies from large to small in the middle of the filter screen.

[0007] The sewage discharge assembly includes a transmission pipe with an opening and a sewage discharge section, and a spiral transmission shaft rotatably connected to the transmission pipe. The opening is located inside the housing and faces the impurity collection area, while the sewage discharge section is located outside the housing and is used to discharge impurities outside the housing.

[0008] Furthermore, the transmission tube is provided with multiple openings.

[0009] Furthermore, the plurality of openings are arranged at circumferential intervals along the transmission tube.

[0010] Furthermore, one end of the transmission pipe is connected to the bottom of the housing, and the other end extends outward through the bottom of the housing to form a drain section outside the housing.

[0011] Furthermore, the length of the spiral transmission shaft is greater than the length of the transmission shaft.

[0012] Furthermore, the drainage filtration device also includes an operating handle with multiple rotating links, the operating handle being detachably connected to the spiral transmission shaft, and the operating handle being used to drive the spiral transmission shaft to rotate relative to the transmission pipe.

[0013] Furthermore, the spiral transmission shaft is provided with a limiting hole for at least one of the rotating connecting rods to extend into.

[0014] Furthermore, the drainage filtration device also includes a cover that is fitted onto the transmission pipe.

[0015] Furthermore, the housing is also provided with a drain outlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the building construction water supply and drainage filtration device provided by this utility model, an impurity collection area with varying sizes is formed in the middle of the filter screen. When the filter screen filters sewage, the impurities filtered by the filter screen will accumulate in the impurity collection area. The opening is directly opposite the impurity collection area, allowing the impurities to fall into the transmission pipe. Finally, the rotating spiral transmission shaft transports the impurities, allowing them to move along the direction of the sewage discharge section, thereby separating the impurities from the shell. This changes the existing technology that requires disassembling the filter screen to clean the impurities, and has the advantages of simple operation and fast cleaning speed.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1 to 4 The image shows a water supply and drainage filtration device for building construction in one embodiment of the present invention, including a sewage discharge component 100 and a filter screen 300 disposed in a housing 200. The housing 200 is used to connect to a drain pipe 600. It should be noted that in this embodiment, the drain pipe 600 is mainly used to discharge sewage from the construction site. In order to prevent sewage from polluting the construction environment, it is necessary to filter harmful impurities in the sewage.

[0027] Therefore, in this embodiment, the filter screen 300 has a plurality of outer edge portions 310, each outer edge portion 310 being connected to each inner wall of the housing 200, and the relative height of each outer edge portion 310 extending toward the interior of the housing 200 from high to low, so as to form an impurity collection area 320 with a size varying from large to small in the middle of the filter screen 300.

[0028] The sewage discharge assembly 100 includes a transmission pipe 110 with an opening 111 and a sewage discharge section 112, and a spiral transmission shaft 120 rotatably connected to the transmission pipe 110. The opening 111 is located inside the housing 200 and faces the impurity collection area 320. The sewage discharge section 112 is located outside the housing 200 and is used to discharge impurities outside the housing 200.

[0029] Specifically, in this embodiment, by forming an impurity collection area 320 with varying sizes in the middle of the filter screen 300, when the filter screen 300 filters wastewater, the impurities filtered by the filter screen 300 will accumulate in the impurity collection area 320. With the opening 111 facing the impurity collection area 320, the impurities can fall into the transmission pipe 110. Finally, the rotating spiral transmission shaft 120 is used to transport the impurities, allowing them to move along the direction of the discharge section 112, thereby separating the impurities from the housing 200. This changes the existing technology where the filter screen 300 needs to be disassembled to clean the impurities, and has the advantages of simple operation and fast cleaning speed.

[0030] For a further understanding of this case, please refer to Figure 4 As shown, Figure 4 The circular outline represents the impurities accumulated in the impurity collection area 320. The filter screen 300 has a structure that is high around the edges and low in the middle. One end of the transmission pipe 110 is connected to the bottom of the housing 200, and the other end extends outward through the bottom of the housing 200 to form a drain section 112 outside the housing 200. Specifically, the opening 111 on the transmission pipe 110 can be directly opposite the lowest point of the impurity collection area 320 and can be flush with the lowest point, so that the impurities accumulated in the impurity collection area 320 can smoothly enter the transmission pipe 110.

[0031] Furthermore, the length of the spiral transmission shaft 120 is greater than the length of the transmission shaft. By limiting the length of the spiral transmission shaft 120, when impurities are transported to the top of the spiral transmission shaft 120, they can fall directly onto the outer top of the housing 200, which is beneficial for subsequent centralized cleaning of impurities.

[0032] In some embodiments, the bottom of the spiral transmission shaft 120 can be connected to the bottom inner wall of the housing 200 via a bearing, which can improve the smoothness of the rotation of the spiral transmission shaft 120.

[0033] In addition, to improve the speed of cleaning impurities, in some preferred embodiments, the transmission pipe 110 is provided with a plurality of openings 111, and the plurality of openings 111 are arranged at intervals along the circumference of the transmission pipe 110.

[0034] To facilitate the rotation of the spiral transmission shaft 120, the drainage filter also includes an operating handle 400 with multiple rotating links. The operating handle 400 is detachably connected to the spiral transmission shaft 120. The operating handle 400 is used to drive the spiral transmission shaft 120 to rotate relative to the transmission pipe 110, and the spiral transmission shaft 120 is provided with a limiting hole 121 for at least one rotating link to extend into.

[0035] In addition, when it is not necessary to clean the impurities on the filter screen 300, in order to prevent external particles from entering the transmission pipe 110, in this embodiment, the drainage filter device also includes a cover 500, which is connected to the transmission pipe 110. In addition, the housing 200 is also provided with a drain outlet 210, which can discharge the filtered sewage.

[0036] In summary, the water supply and drainage filtration device for building construction according to one embodiment of the present invention has at least the following advantages compared to the prior art drainage filtration devices:

[0037] In the building construction water supply and drainage filtration device provided by this utility model, an impurity collection area 320 with varying sizes is formed in the middle of the filter screen 300. When the filter screen 300 filters sewage, the impurities filtered by the filter screen 300 will accumulate in the impurity collection area 320. The opening 111 is directly opposite the impurity collection area 320, allowing the impurities to fall into the transmission pipe 110. Finally, the rotating spiral transmission shaft 120 is used to transport the impurities, allowing them to move along the direction of the sewage discharge section 112, thereby separating the impurities from the housing 200. This changes the existing technology where the filter screen 300 needs to be disassembled to clean the impurities, and has the advantages of simple operation and fast cleaning speed.
