Description

Technical Field

[0001] This invention belongs to the field of wastewater purification and treatment technology, and particularly relates to an integrated wastewater purification and treatment device for building engineering. Background Technology

[0002] Construction engineering refers to comprehensive engineering activities involving the planning, design, construction, and maintenance of various buildings and structures such as houses, roads, and bridges. It encompasses multiple professional fields, including civil engineering structures, water supply and drainage, and electrical installation. In modern construction engineering, the concepts of environmental protection and sustainable development are receiving increasing attention, and wastewater treatment is an important component of this. By integrating wastewater collection and treatment systems into projects, it is possible not only to effectively reduce environmental pollution but also to achieve the recycling of water resources and improve the overall green performance and efficiency of buildings.

[0003] In existing construction wastewater treatment technologies, traditional pretreatment methods typically rely on simple filters at the inlet to initially intercept the large amounts of particulate impurities such as sand and gravel commonly found in wastewater. However, such structures are mostly static filters, lacking dynamic drive and effective impurity discharge mechanisms. As a result, impurities easily accumulate during use, and the filters are prone to clogging. Once clogged, this not only restricts the normal flow of wastewater, causing subsequent treatment stages to be unable to operate continuously, but also causes equipment instability, increases maintenance frequency, and affects the overall treatment efficiency and continuity of the system. In addition, such structures usually do not have a centralized discharge function for impurities, and sand and gravel cannot be effectively separated and removed, further increasing the burden on system operation and making it difficult to meet the actual needs of high-pollution environments such as construction sites for efficient filtration and treatment of solid particles in wastewater.

[0004] Based on this, the present invention designs an integrated wastewater purification and treatment device for building engineering to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem that in existing building wastewater treatment technologies, when faced with a large number of particulate impurities such as sand and gravel commonly found in wastewater, traditional pretreatment methods typically rely on setting up simple filter screens at the inlet for initial interception. However, such structures are mostly static filters, lacking dynamic drive and effective impurity discharge mechanisms, leading to the easy accumulation of impurities and easy clogging of the filter screen during use. Therefore, this invention proposes an integrated wastewater purification and treatment device for building engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated wastewater purification and treatment device for building engineering includes a filter tank, a purification tank fixedly connected to one side of the filter tank, a treatment tank fixedly connected to one side of the purification tank, a discharge pipe running through the treatment tank, a filter device installed in the filter tank, a cleaning device clamped on the outside of the filter device, water absorption components on both the filter tank and the treatment tank, and a purification stirring component installed in the purification tank.

[0008] The filtration device includes two filter cylinders and a drive motor. A sealing plate is installed between the two filter cylinders. A first reel is fitted over the sealing plate. The drive motor is fixedly connected to the filter tank. A second reel is fixedly connected to the output end of the drive motor. The first and second reels are fitted with the same belt. Rotary drums are installed on the opposite sides of the two filter cylinders. Connecting plates are rotatably connected to the outside of the two rotating drums. The two connecting plates are fixedly connected inside the filter tank.

[0009] As a further description of the above technical solution:

[0010] The filtration device also includes two sealed bearings and a rectangular groove. The two sealed bearings are respectively sleeved on the outside of the two rotating cylinders and are connected through the filter tank. A feed pipe is provided through one end of the rotating cylinder, and an installation plate is fixedly connected to the outside of the feed pipe. The installation plate is fixedly connected to the front of the filter tank.

[0011] As a further description of the above technical solution:

[0012] The rectangular groove is formed inside the filter tank, and the belt is located inside the rectangular groove.

[0013] As a further description of the above technical solution:

[0014] The filter cylinder is set at a certain angle and the feed end is at a high position, and a baffle is installed inside one of the rotating cylinders.

[0015] As a further description of the above technical solution:

[0016] The diameter of the feed pipe cross-section is slightly smaller than the inner diameter of the rotating drum, and the two form a rotating connection.

[0017] As a further description of the above technical solution:

[0018] The cleaning device includes a connecting seat, which is fixedly connected to one side of the filter tank. A water pump is fixedly connected to the connecting seat, and a Y-shaped pipe is fixedly connected to the output end of the water pump. The Y-shaped pipe passes through the filter tank, and two connecting pipes are fixedly connected to one side of the Y-shaped pipe. Pipes are fixedly connected to one side of each of the two connecting pipes. A water collection cover is fitted over the pipes, and an arc-shaped plate is fixedly connected to one side of the water collection cover. The arc-shaped plate overlaps the outside of the filter cylinder.

[0019] As a further description of the above technical solution:

[0020] The mating surfaces of the arc-shaped plate and the filter cylinder are provided with smooth surfaces to reduce friction, and the length of the arc-shaped plate is slightly less than the length of the filter cylinder.

[0021] As a further description of the above technical solution:

[0022] The cleaning device also includes a drain pipe and a housing. The drain pipe is fixedly connected to the output end of the water pump, and a drain nozzle is fitted onto one end of the drain pipe.

[0023] As a further description of the above technical solution:

[0024] The box is fixedly connected to one side of the filter tank. A filter screen is installed inside the box. A return pipe is provided through the bottom of the box and is connected through the filter tank.

[0025] As a further description of the above technical solution:

[0026] The drain pipe is designed in a C-shape to facilitate drainage through bends.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In this invention, during wastewater treatment, the wastewater to be treated is first introduced into the system through the feed pipe. The wastewater sequentially enters the rotating drum and further flows into the filter cylinders installed inside the rotating drum. Subsequently, the drive motor is started, driving the second reel to rotate. Through the belt drive mechanism, the first reel rotates synchronously. When the first reel rotates, it drives the connected sealing plate to rotate. The sealing plate further drives the two filter cylinders to rotate synchronously. As the filter cylinders rotate, they drive the rotating drum to rotate synchronously between the connecting plate and the sealing bearing. During the rotation of the filter cylinders, a stable centrifugal force field is formed inside the system, promoting... Lighter water in the wastewater is ejected from the filter holes in the filter cylinder wall and discharged into the external filter tank. After preliminary filtration, the wastewater is drawn in by the water suction component and transported to the purification tank. In the purification tank, it is mixed and purified by the purification stirring component, thereby further improving the purification effect of the water quality. At the same time, heavier sand and gravel particles inside the filter cylinder are deposited at the bottom of the rotating cylinder under centrifugal force. When the sand and gravel accumulate to a certain amount, the corresponding baffle can be opened. Using the tilt angle set by the filter cylinder itself, the sand and gravel are automatically discharged to the open rotating cylinder outlet by gravity, completing the directional separation and discharge of solid impurities.

[0029] 2. In this invention, when the filter cylinder rotates, the water pump is started. When the water pump is running, the negative pressure suction is transmitted to the connecting pipe and pipeline system through the Y-shaped pipe. A stable local suction field is formed outside the rotating cylinder through the water collection cover and the arc plate area. This suction acts on the water collection cover on the outside of the rotating cylinder, realizing continuous suction of the rotating cylinder and the filter cylinder inside. During this process, the sand and gravel impurities accumulated inside the filter cylinder or at the filter holes are sucked up in time, effectively avoiding the accumulation and blockage of impurities inside the cylinder. The sucked sand and gravel and some sewage are discharged together along the drain pipe channel and introduced into the box set below through the drain nozzle. The box is equipped with a filter screen to further separate the sucked material. Larger sand and gravel particles are intercepted by the filter screen, while sewage flows into the bottom of the box after passing through the filter screen and is finally transported back to the filter tank through the return pipe to realize the recycling of sewage. The above structural design effectively improves the filtration efficiency, anti-clogging ability and continuous operation of the system, ensuring that sewage can still complete the preliminary treatment and impurity discharge process efficiently and stably under the condition of containing high concentration of particulate impurities.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0039] Please see Figures 1-6 The present invention provides a technical solution: an integrated sewage purification and treatment device for building engineering, including a filter tank 1, a purification tank 2 fixedly connected to one side of the filter tank 1, a treatment tank 3 fixedly connected to one side of the purification tank 2, a discharge pipe 4 passing through the treatment tank 3, a filter device 5 installed in the filter tank 1, a cleaning device 6 clamped on the outside of the filter device 5, a water absorption component 7 on both the filter tank 1 and the treatment tank 3, and a purification stirring component 8 installed in the purification tank 2.

[0040] The filtration device 5 includes two filter cylinders 505 and a drive motor 510. A sealing plate 506 is installed between the two filter cylinders 505. A first roller 507 is fitted over the sealing plate 506. The drive motor 510 is fixedly connected to the filter tank 1. A second roller 508 is fixedly connected to the output end of the drive motor 510. The first roller 507 and the second roller 508 are fitted with the same belt 509. The first roller 507 and the second roller 508 share a belt 509 for transmission. This belt 509 transmission method has the advantages of simple structure, smooth operation and high transmission efficiency. Through this cooperation, the drive motor 510 can transmit power to the filter cylinders 505 synchronously and evenly, avoiding the problem of vibration or deflection of the filtration device 5 due to uneven transmission, thereby improving the reliability and service life of the entire filtration system.

[0041] Two filter cylinders 505 are each mounted with a rotating cylinder 502 on their opposite sides. Both rotating cylinders 502 are rotatably connected to a connecting plate 501, and the two connecting plates 501 are fixedly connected inside the filter tank 1.

[0042] Specifically, such as Figure 2-3 As shown, the filter device 5 also includes two sealed bearings 503 and a rectangular groove 511. The two sealed bearings 503 are respectively sleeved on the outside of the two rotating cylinders 502. The sealed bearings 503 are sleeved on the outside of the rotating cylinders 502 and adopt a tight interference fit, which can effectively prevent sewage from seeping into the bearing cavity during the rotation of the rotating cylinders 502, preventing dirt from corroding and causing bearing failure. This fit not only improves the sealing performance of the rotating parts, but also enhances the durability and working stability of the filter cartridge 505 system in high humidity and high pollution environments.

[0043] Two sealed bearings 503 are connected through the filter tank 1. One end of the rotating drum 502 is provided with a feed pipe 504. An installation plate 512 is fixedly connected to the outside of the feed pipe 504. The installation plate 512 is fixedly connected to the front of the filter tank 1. A rectangular groove 511 is opened in the filter tank 1, and the belt 509 is located in the rectangular groove 511. The filter cylinder 505 is set in an inclined shape with a certain angle, and the feed end is at a high position. A baffle 9 is installed in one of the rotating drums 502. The diameter of the cross-section of the feed pipe 504 is slightly smaller than the inner diameter of the rotating drum 502, and the two form a rotating connection.

[0044] Specifically, such as Figure 4-6As shown, the cleaning device 6 includes a connecting seat 601, which is fixedly connected to one side of the filter tank 1. A water pump 602 is fixedly connected to the connecting seat 601. A Y-shaped pipe 603 is fixedly connected to the output end of the water pump 602. The Y-shaped pipe 603 passes through the filter tank 1. Two connecting pipes 604 are fixedly connected to one side of the Y-shaped pipe 603. One end of the Y-shaped pipe 603 is connected to both connecting pipes 604 at the same time, forming a symmetrical diversion structure. This design allows the water flow output by the water pump 602 to be evenly distributed to two directions, effectively improving the coverage of the suction outside the filter cartridge 505, realizing simultaneous cleaning of the two filter cartridges 505, enhancing cleaning efficiency and reducing the risk of single-point blockage.

[0045] Two connecting pipes 604 are fixedly connected to one side of a pipe 605. A water collection cover 606 is fitted over the pipe 605. An arc-shaped plate 607 is fixedly connected to one side of the water collection cover 606. The arc-shaped plate 607 overlaps the outside of the filter cylinder 505. The contact surface between the arc-shaped plate 607 and the filter cylinder 505 is set as a smooth surface. This surface design effectively reduces the frictional resistance generated when the filter cylinder 505 contacts the arc-shaped plate 607 during rotation. By reducing contact friction, not only can the service life of the filter cylinder 505 and the arc-shaped plate 607 be extended, but the stability and efficiency of the filter cylinder 505 during rotation can also be ensured, which helps to maintain the continuous operation of the filtration system.

[0046] The mating surfaces of the arc plate 607 and the filter cylinder 505 are provided with smooth surfaces to reduce friction. The length of the arc plate 607 is slightly less than the length of the filter cylinder 505. The cleaning device 6 also includes a drain pipe 608 and a box 610. The drain pipe 608 is fixedly connected to the output end of the water pump 602. One end of the drain pipe 608 is fitted with a drain nozzle 609. The box 610 is fixedly connected to one side of the filter tank 1. A filter screen 611 is installed inside the box 610. The filter screen 611 is installed inside the box 610 and is firmly positioned by fitting and embedding to ensure that it will not shift or fall off under the impact of water flow. This fit structure is simple and easy to disassemble and clean. At the same time, it can achieve efficient interception of sand and gravel particles in the water, provide pure fluid for subsequent sewage return, and help maintain the stability of the water quality in the filter tank 1.

[0047] A return pipe 612 is provided through the bottom of the box body 610, and the return pipe 612 is connected through the filter tank 1. The drain pipe 608 is designed in a C-shape to facilitate drainage by turning.

[0048] Working principle and usage: During wastewater treatment, the wastewater to be treated is first introduced into the system through the feed pipe 504. The wastewater sequentially enters the rotating drum 502 and further flows into the filter cylinder 505 located inside the rotating drum 502. Subsequently, the drive motor 510 is started, which drives the second winding wheel 508 to rotate. Through the belt transmission mechanism 509, the first winding wheel 507 rotates synchronously. When the first winding wheel 507 rotates, it drives the connected sealing plate 506 to rotate. The sealing plate 506 further drives the two filter cylinders 505 to rotate synchronously. As the filter cylinders 505 rotate, they drive the rotating drum... 502 rotates synchronously between the connecting plate 501 and the sealing bearing 503. During the rotation of the filter cylinder 505, a stable centrifugal force field is formed inside the system, causing the lighter water in the wastewater to be thrown out through the filter holes in the wall of the filter cylinder 505 and discharged into the external filter tank 1. The wastewater after preliminary filtration is sucked in by the water suction component 7 and transported to the purification tank 2. In the purification tank 2, it is mixed and purified by the purification stirring component 8, thereby further improving the purification effect of the water quality. At the same time, the heavier sand and gravel particles inside the filter cylinder 505 are deposited at the bottom of the rotating cylinder 502 under centrifugal action. When the sand and gravel accumulate to a certain level... When measuring the quantity, the corresponding baffle 9 can be opened. Utilizing the tilt angle set by the filter cylinder 505 itself, the sand and gravel are automatically discharged to the open discharge port of the rotating drum 502 by gravity. While the filter cylinder 505 is rotating, the water pump 602 is started. When the water pump 602 is running, the negative pressure suction is transmitted to the connecting pipe 604 and pipeline 605 system through the Y-shaped pipe 603. A stable local suction field is formed outside the rotating drum 502 through the water collection hood 606 and the arc-shaped plate 607 area. This suction acts on the water collection hood 606 covering the outside of the rotating drum 502, thus achieving suction on the rotating drum 502 and its internal filter cylinder 505. During continuous suction, sand and gravel impurities accumulated inside the filter cylinder 505 or at the filter holes are promptly sucked up, effectively preventing the accumulation and clogging of impurities inside the cylinder. The sucked-up sand and gravel and some sewage are discharged together along the drain pipe 608 and introduced into the box 610 located below through the drain nozzle 609. The box 610 is equipped with a filter screen 611, which further separates the sucked-up material. Larger sand and gravel particles are intercepted by the filter screen 611, while sewage flows through the filter screen 611 and flows into the bottom of the box 610. Finally, it is transported back to the filter tank 1 through the return pipe 612, realizing the recycling of sewage.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
