Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline filtering field, specifically, relate to a pipeline filtering device for water supply and drainage engineering. BACKGROUND

[0002] In the drainage system, solid waste, hair, fiber and other impurities in sewage are easy to accumulate in the pipeline, causing pipeline blockage. Especially in the kitchen, bathroom and other drainage points, there are more impurities such as oil and hair. Installing a pipeline filter can intercept impurities before they enter the main drainage pipeline, reducing the probability of pipeline blockage and reducing maintenance costs and maintenance workload.

[0003] During the filtering process, since there are many impurities in the wastewater, the impurities will accumulate during filtering, thereby causing the filtering device to be blocked. However, the existing filtering device usually removes the filtering device for dredging when dealing with blockage, which is time-consuming and labor-intensive.

[0004] Therefore, we improve it and propose a pipeline filtering device for water supply and drainage engineering. UTILITY MODEL CONTENT

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As in the background art, impurities accumulate during filtration, which in turn causes clogging of the filtration device.

[0032] To solve this technical problem, this utility model provides a pipe filtration device for water supply and drainage engineering, which is used to stir and clear blockages of impurities during the filtration process.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] A pipeline filtration device for water supply and drainage engineering includes a filter box 1. A filter disc 101 is fixedly connected to the lower surface of the filter box 1. A support rod 102 is rotatably connected to the center of the filter disc 101. A connecting rod 103 is fixedly connected to the outer surface of the support rod 102. A stirring blade 104 is fixedly connected to both ends of the connecting rod 103. The stirring blade 104 is spirally shaped. A connecting shaft 105 is fixedly connected to the upper end of the support rod 102. A plurality of guide plates 106 are arranged in a ring on the outer surface of the connecting shaft 105. The guide plates 106 are spirally inclined from the upper end to the lower end.

[0037] During the impurity removal and filtration process, wastewater enters the guide block 2 inside the filter box 1 along the water supply pipe 301 and the connecting pipe 3. At this time, the wastewater flows along the guide block 2 to the top of the guide plate 106. When passing the guide plate 106, the gravity of the water flowing downward and the pressure on the guide plate 106 cause the guide plate 106 to rotate, which in turn causes the support rod 102 to rotate. The rotation of the support rod 102 will drive the stirring plate 104 and the scraper 5 to rotate. The rotation of the stirring plate 104 will clear the accumulated impurities, and the rotation of the scraper 5 will clean the impurities.

[0038] A guide block 2 is fixedly connected to the upper end of the connecting shaft 105, and the guide block 2 retracts from the lower end to the upper end.

[0039] The guide block 2, which is fixedly connected to the upper end of the connecting shaft 105, can divert wastewater from the top along the outer surface to the guide plate 106 for conveying.

[0040] A connecting pipe 3 is connected to the upper surface of the filter box 1. The connecting pipe 3 bends from one end to the other end, and a water supply pipe 301 is connected to the end of the connecting pipe 3 away from the filter box 1.

[0041] The connecting pipe 3 connected to the upper surface of the filter box 1 and the water supply pipe 301 connected to the end of the connecting pipe 3 away from the filter box 1 can transport wastewater to the inside of the filter box 1 for filtration.

[0042] The lower surface of the filter box 1 is connected to a water storage tank 4, and the side of the water storage tank 4 away from the water supply pipe 301 is connected to a drain pipe 401.

[0043] The water storage tank 4 connected to the lower surface of the filter box 1 is used to collect the filtered wastewater. The drain pipe 401 connected to the side of the water storage tank 4 away from the water supply pipe 301 can discharge the filtered wastewater, thus realizing the filtration operation.

[0044] The upper surface of the filter disc 101 is abutted by a scraper 5, which is fixedly connected to the outer surface of the support rod 102. The lower surface of the filter disc 101 is provided with a groove 501, which is inclined.

[0045] The scraper 5, which abuts against the upper surface of the filter disc 101, can scrape the impurities accumulated on the filter disc 101 to the slot 501. The accumulated impurities enter the conveying pipe 6 along the slot 501 for collection. Since the scraper 5 is fixedly connected to the support rod 102, when the support rod 102 rotates, it can drive the scraper 5 to rotate, thus clearing the impurities.

[0046] The end of the slot 501 furthest from the support rod 102 is connected to a material conveying pipe 6, the other end of the material conveying pipe 6 is connected to a waste bin 601, and the outer surface of the waste bin 601 is connected to a discharge pipe 602.

[0047] The conveying pipe 6 connected to the end of the slot 501 away from the support rod 102 is used to transport the impurities that are being stirred to the waste bin 601. The waste bin 601 connected to the other end of the conveying pipe 6 is used to collect the filtered impurities. The discharge pipe 602 connected to the outer surface of the waste bin 601 is used to discharge the collected impurities for processing.

[0048] There are two filter discs 101, and the radius of the upper filter hole is larger than that of the lower filter hole.

[0049] The filter disc 101 is configured with two discs for graded filtration to improve the filtration efficiency of impurities. The upper filter hole radius is larger than the lower filter hole radius to achieve graded filtration of impurities.

[0050] The usage process of the pipeline filtration device for water supply and drainage engineering provided by this utility model is as follows:

[0051] During the impurity removal and filtration process, wastewater enters the guide block 2 inside the filter box 1 along the water supply pipe 301 and the connecting pipe 3. At this time, the wastewater flows along the guide block 2 to the top of the guide plate 106. When it passes the guide plate 106, the gravity of the water flowing downward and the pressure on the guide plate 106 cause the guide plate 106 to rotate, which in turn causes the support rod 102 to rotate. The rotation of the support rod 102 will cause the stirring plate 104 and the scraper 5 to rotate. The rotation of the stirring plate 104 will clear the accumulated impurities, and the rotation of the scraper 5 will clean the impurities.

[0052] The scraper 5, which abuts against the upper surface of the filter disc 101, can scrape the impurities accumulated on the filter disc 101 to the slot 501. The accumulated impurities enter the conveying pipe 6 along the slot 501 for collection. Since the scraper 5 is fixedly connected to the support rod 102, when the support rod 102 rotates, it can drive the scraper 5 to rotate, thus clearing the impurities.
