Description

Technical Field

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

[0002] The water supply and drainage system in building construction is an indispensable infrastructure component of modern urban development. It mainly comprises two parts: the water supply system and the drainage system. The water supply system is responsible for providing clean water for daily life and production needs, and typically includes four main stages: water source supply, water treatment, water distribution, and indoor water supply. The drainage system is responsible for discharging domestic sewage and industrial wastewater from buildings to prevent them from harming the environment and public health. The drainage system typically includes three stages: wastewater collection, transportation, and treatment. Water supply and drainage filtration is a crucial component of the system, playing a vital role in ensuring water quality safety and environmental protection.

[0003] A building engineering water supply and drainage filtration device, disclosed in Chinese Patent No. CN220100122U, includes a drainage pipe, a sewer well connected to the drainage pipe and located above it, and a grate at the inlet of the sewer well. It also includes a filtration device inside the sewer well and collection boxes on both sides of the sewer well. The filtration device comprises two filter screens arranged in a triangle with the top of the triangle facing the grate. The two filter screens divide the sewer well cavity into an upper filtration area and a lower discharge area. Impurity collection ports, connected to the collection boxes, are respectively provided on the sewer well wall, inside the filtration area, and at the bottom of the two filter screens. This invention has a simple structure and enables the filtration and collection of building material debris, preventing it from entering the urban drainage system and causing blockages.

[0004] With the rapid development of technology, the above-mentioned device has the following shortcomings:

[0005] 1. During the wastewater filtration process, the above-mentioned device cannot automatically discharge the filtered impurities. It can only collect the impurities through a collection box, which requires manual cleaning afterward. This increases the labor burden on workers and affects the efficiency of water supply and drainage.

[0006] 2. After a period of use, some easily adsorbed impurities will be adsorbed on the filter screen, causing the filter screen to become clogged and further affecting the water supply and drainage efficiency. Utility Model Content

[0007] This utility model proposes a water supply and drainage filtration device for building engineering. The filtered impurities can be automatically discharged without manual cleaning, reducing the labor burden of workers and preventing easily adsorbed impurities from adsorbing onto the filter screen, causing filter screen blockage and avoiding affecting water supply and drainage efficiency.

[0008] This utility model is implemented as follows: a building engineering water supply and drainage filtration device includes a box, a filter screen cylinder is provided inside the box, and an impurity discharge and cleaning mechanism is provided inside the filter screen cylinder.

[0009] The impurity discharge and cleaning mechanism includes a cylindrical impurity discharge trough fixedly connected to the right side wall of the housing. A conveyor is installed inside the impurity discharge trough. The left end of the impurity discharge trough passes through the housing and the filter cylinder and extends to the inner left end of the filter cylinder. A rotating shaft is rotatably connected to the left inner side wall of the housing. The right end of the rotating shaft extends into the filter cylinder and is rotatably connected to the left end of the impurity discharge trough. An installation plate located inside the filter cylinder is fixedly connected to the outer wall of the rotating shaft. Scrapers that abut against the inner wall of the filter cylinder are fixedly connected to the upper and lower end faces of the installation plate.

[0010] As a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, a drive motor is installed on the left side wall of the box, and the output end of the drive motor is fixedly connected to the rotating shaft.

[0011] As a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, a plurality of evenly distributed fixing rods are fixedly connected between the upper inner end of the box body and the upper outer wall of the filter screen cylinder.

[0012] As a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, a water inlet pipe is fixedly connected to the left side wall of the box, one end of the water inlet pipe extends into the interior of the box and communicates with the filter screen cylinder, and a quick-release connector is installed at the other end of the water inlet pipe.

[0013] As a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, the lower end face of the box is connected to a drainage pipe, and the lower end of the interior of the box is configured as a funnel structure.

[0014] As a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, both scrapers are made of superhydrophobic materials (such as PTFE / Teflon) and have a smooth surface structure.

[0015] In a preferred embodiment of the building engineering water supply and drainage filtration device of this utility model, the opposite side walls of the two scrapers abut against the outer wall of the waste discharge trough.

[0016] The beneficial effects of this utility model are:

[0017] Two rotating scrapers lift up the impurities filtered by the filter cylinder. Simultaneously, the scrapers remove impurities adsorbed on the filter cylinder, preventing easily adsorbed impurities from clogging the inner wall. The scrapers then push the impurities towards the upper interior of the filter cylinder until they reach the opening of the discharge trough. The impurities slide down the scraper and into the discharge trough, where a conveyor discharges them from the filter cylinder. This automatic discharge of filtered impurities eliminates the need for manual cleaning, reducing labor burden and preventing disruption to water supply and drainage efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 A building engineering water supply and drainage filtration device includes a box 1, a filter cylinder 2 is provided inside the box 1, and an impurity discharge and cleaning mechanism is provided inside the filter cylinder 2.

[0026] The impurity discharge and cleaning mechanism includes a cylindrical impurity discharge trough 3 fixedly connected to the right side wall of the housing 1. A conveyor 11 is installed inside the impurity discharge trough 3. The left end of the impurity discharge trough 3 passes through the housing 1 and the filter cylinder 2 and extends to the left end of the filter cylinder 2. A rotating shaft 4 is rotatably connected to the left inner side wall of the housing 1. The right end of the rotating shaft 4 extends into the filter cylinder 2 and is rotatably connected to the left end of the impurity discharge trough 3. An installation plate 5 located inside the filter cylinder 2 is fixedly connected to the outer wall of the rotating shaft 4. Scrapers 6 that abut against the inner wall of the filter cylinder 2 are fixedly connected to the upper and lower end faces of the installation plate 5.

[0027] In this embodiment: when filtering sewage, the rotating shaft 4 rotates, and the rotating shaft 4, together with the mounting plate 5, drives the two scrapers 6 to rotate around the rotating shaft 4. Since the scrapers 6 abut against the inner wall of the filter cylinder 2, the rotating scrapers 6 can scrape up the impurities filtered out by the filter cylinder 2. At the same time, the scrapers 6 can remove the impurities adsorbed on the filter cylinder 2, preventing easily adsorbed impurities from adsorbing onto the inner wall of the filter cylinder 2 and causing blockage. Then, by pushing the scrapers 6, the impurities move towards the upper part of the filter cylinder 2. During the movement, the sewage on the scrapers 6 flows to the left and right sides of the scrapers 6. The filter is filtered through the left and right side walls of the filter cylinder 2 until the scraper 6 rotates to the opening of the discharge trough 3. At the same time, as the scraper 6 rotates, the tilt angle of the scraper 6 becomes steeper and steeper. Since both scrapers 6 are made of superhydrophobic materials (such as PTFE / Teflon) and have a smooth surface, impurities can slide down along the scraper 6 and enter the discharge trough 3. Then, the conveyor 11 in the discharge trough 3 discharges the impurities from the filter cylinder 2, thereby automatically discharging the filtered impurities without the need for manual cleaning, reducing the labor burden of workers and avoiding affecting the efficiency of water supply and drainage.

[0028] Since the opposite sidewalls of the two scrapers 6 are in contact with the outer wall of the discharge trough 3, impurities will not fall through the gap between the scraper 6 and the outer wall of the discharge trough 3 when the scraper 6 is not rotated to the opening of the discharge trough 3, thus effectively treating the impurities.

[0029] As a technical optimization of this utility model, a drive motor 7 is installed on the left side wall of the housing 1, and the output end of the drive motor 7 is fixedly connected to the rotating shaft 4.

[0030] In this embodiment, the drive motor 7 can drive the rotating shaft 4 to rotate.

[0031] As a technical optimization of this utility model, a plurality of evenly distributed fixing rods 8 are fixedly connected between the upper inner end of the housing 1 and the upper outer wall of the filter cylinder 2.

[0032] In this embodiment, the filter cylinder 2 can be fixed by multiple fixing rods 8.

[0033] As a technical optimization of this utility model, a water inlet pipe 9 is fixedly connected to the left side wall of the box 1. One end of the water inlet pipe 9 extends into the interior of the box 1 and is connected to the filter screen cylinder 2. A quick-release connector is installed at the other end of the water inlet pipe 9.

[0034] In this embodiment: the inlet pipe 9 facilitates the delivery of sewage into the filter cylinder 2, and the quick-release connector facilitates the connection of the external water pipe to the inlet pipe 9.

[0035] As a technical optimization of this utility model, the lower end face of the box 1 is connected to a drainage pipe 10, and the lower end of the interior of the box 1 is set as a funnel structure.

[0036] In this embodiment, the filtered sewage in the tank 1 can be discharged through the drainage pipe 10. The lower end of the tank 1 is set as a funnel structure, which allows the filtered sewage to be discharged cleanly from the tank 1.

[0037] As a technical optimization of this utility model, both scrapers 6 are made of superhydrophobic materials (such as PTFE / Teflon) and have a smooth surface structure.

[0038] In this embodiment, both scrapers 6 are made of superhydrophobic materials (such as PTFE / Teflon) and have a smooth surface structure, which allows impurities to slide downwards along the scrapers 6.

[0039] As a technical optimization of this utility model, the opposite side walls of the two scrapers 6 abut against the outer wall of the waste discharge trough 3.

[0040] In this embodiment, the opposite sidewalls of the two scrapers 6 are in contact with the outer wall of the impurity discharge groove 3. When the scraper 6 is not rotated to the opening of the impurity discharge groove 3, impurities will not fall through the gap between the scraper 6 and the outer wall of the impurity discharge groove 3, thus effectively treating the impurities.

[0041] The working principle and usage process of this utility model are as follows: When in use, first connect the external water pipe to the water inlet pipe 9 through the quick-release connector, and then transport sewage into the filter screen cylinder 2 through the external water pipe and the water inlet pipe 9. After the sewage enters the filter screen cylinder 2, it can be filtered through the filter screen cylinder 2. The filtered sewage enters the box 1 and is discharged through the drain pipe 10, thereby filtering the sewage.

[0042] While filtering the wastewater, the drive motor 7 is started, which drives the rotating shaft 4 to rotate. The rotating shaft 4, together with the mounting plate 5, drives the two scrapers 6 to rotate around the rotating shaft 4. The two rotating scrapers 6 can scrape up the impurities filtered by the filter cylinder 2. At the same time, the scrapers 6 can remove the impurities adsorbed on the filter cylinder 2. Then, the scrapers 6 push the impurities to move towards the upper part of the filter cylinder 2. During the movement, the wastewater on the scrapers 6 flows to the left and right sides of the scrapers 6 and is filtered through the left and right side walls of the filter cylinder 2. When the scrapers 6 rotate to the opening of the discharge trough 3, the impurities slide down along the scrapers 6 and enter the discharge trough 3. Then, the conveyor 11 in the discharge trough 3 discharges the impurities from the filter cylinder 2, thereby automatically discharging the filtered impurities.
