Description

Technical Field

[0001] This application relates to the field of construction wastewater utilization technology, specifically a building construction wastewater recycling and reuse device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called a "construction site" or "building site." During the construction process, a lot of mud and wastewater is generated. At the construction site, some of this wastewater is collected, settled, and then reused.

[0003] An existing patent (publication number: CN215654245U) discloses a device for reusing construction wastewater from building construction. The technology includes an independent clear water tank and a sedimentation tank. A support assembly is installed on the inner wall of the sedimentation tank, and a filter screen is placed on the support assembly. A drain hole with a plug is located at the bottom of the sedimentation tank. The clear water tank and the sedimentation tank are connected by a first pipe and a second pipe arranged sequentially from top to bottom. A second valve is installed on the second pipe. A first outlet pipe and a second outlet pipe are installed on the side wall of the clear water tank. A third valve is installed on the second outlet pipe, and a first valve is installed on the first outlet pipe. This design reduces the amount of silt and impurities in the construction wastewater entering the sedimentation tank through the filter screen. The water in the sedimentation tank can overflow into the clear water tank. When reusing construction wastewater, the water will not become turbid due to water intake. Its structure is simple.

[0004] However, due to the high position of the sedimentation tank, it is not easy to clean the stones and foreign objects intercepted by the filter screen. Secondly, although the bottom of the sedimentation tank is designed with an inner bottom surface that is higher on one side and lower on the other, the sludge is prone to clogging the sewage pipe when treating sludge, and the sludge discharge efficiency is low. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a building wastewater recycling and reuse device, which has advantages such as easy sewage discharge and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a building wastewater recycling and reuse device, including a sedimentation tank, wherein a filter screen with one end inclined downwards is provided at the top of the inner wall of the sedimentation tank;

[0007] The bottom of the sedimentation tank is provided with a sludge pusher block, the upper surface of which is inclined, and the sludge pusher block is slidably connected to the sedimentation tank.

[0008] The sedimentation tank is fixedly connected to both the front and back sides of the sedimentation tank. Threaded rods are rotatably connected between the inner bottom walls of the two drive frames. Drive blocks are threaded to the bottom ends of the two threaded rods. The two drive blocks are slidably connected to the drive frames adjacent to them. Two U-shaped connecting rods are fixedly connected to the surfaces of the two drive blocks. The two U-shaped connecting rods are arranged symmetrically. The filter screen and the sludge pusher are fixedly connected to the two U-shaped connecting rods.

[0009] The above solution utilizes an inclined filter screen to automatically roll and collect stones and foreign objects under gravity, effectively preventing filter clogging caused by distributed accumulation, ensuring filtration efficiency, and reducing manual maintenance costs. The sliding connection design between the sludge pusher and the sedimentation tank, combined with its upward movement on the inclined surface, not only scrapes the inner wall of the sedimentation tank during lifting and lowering to prevent sludge from adhering, but also effectively pushes the bottom sludge upward. The sliding plate facilitates the discharge of sludge and stones. The vibrator installed causes the entire structure to vibrate during the discharge of sludge and stones, facilitating their downward movement and improving sludge removal and waste discharge efficiency.

[0010] Furthermore, a sliding plate is provided on one side of the sedimentation tank, the bottom end of the sliding plate is inclined downwards, and the top end of the sliding plate is fixedly connected to the bottom end of one side of the sedimentation tank.

[0011] The above scheme, through the setting of the sliding plate, can achieve the purpose of automatic discharge of stone and silt.

[0012] Furthermore, a set of support frames is fixedly connected between the slide plate and the sedimentation tank.

[0013] The above solution, through the installation of the support frame, can achieve the purpose of supporting the skateboard and improve its stability.

[0014] Furthermore, a vibrator is fixedly installed on the bottom of the skateboard.

[0015] The above solution, through the setting of the vibrator, can prevent sludge from adhering to the skateboard, and at the same time facilitate the sludge to slide off the sludge pusher and into the skateboard.

[0016] Furthermore, the bottom ends of both threaded rods are fixedly connected to the output end of an external motor.

[0017] The above solution, through the installation of an external motor, can provide power for the rotation of the threaded rod.

[0018] Furthermore, a second pipe is fixedly connected to the bottom of one side of the sedimentation tank.

[0019] The above solution, through the installation of a second pipe, facilitates the connection between the user and the external clear water pool.

[0020] Furthermore, a first pipe is fixedly connected to one side of the sedimentation tank.

[0021] The above solution, through the installation of the first pipe, facilitates the connection between the user and the external clear water pool.

[0022] Furthermore, the surface of the sludge-pushing block is polished.

[0023] The above methods can reduce the friction coefficient of silt and slow down silt adhesion.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This building wastewater recycling device uses an inclined filter screen to automatically roll and collect stones and foreign objects under gravity, effectively avoiding filter screen clogging caused by distributed accumulation, ensuring filtration efficiency, and reducing manual maintenance costs. The sliding connection design between the sludge pusher and the sedimentation tank, combined with its upward movement on the inclined surface, not only scrapes the inner wall of the sedimentation tank during the lifting and lowering process to prevent sludge from adhering, but also effectively pushes the bottom sludge upward. The sliding plate facilitates the discharge of sludge and stones. The vibrator installed causes the whole device to vibrate during the discharge of sludge and stones, facilitating the downward movement of sludge and stones and improving the efficiency of sludge removal and waste discharge.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The wastewater recycling device for building construction in this embodiment includes a sedimentation tank 1. The top of the inner wall of the sedimentation tank 1 is provided with a filter screen 2 with one end tilted downwards. By tilting the filter screen 2, the stone particles can automatically roll down to one end of the filter screen 2 by gravity, thus avoiding distributed accumulation and clogging of the filter screen.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the sedimentation tank 1 is provided with a sludge pusher 3. The upper surface of the sludge pusher 3 is set as an inclined surface. The sludge pusher 3 is slidably connected to the sedimentation tank 1. By setting the sludge pusher 3, it can scrape the inner wall of the sedimentation tank 1 during the lifting and lowering process, so as to prevent sludge from adhering to the inner wall of the sedimentation tank. The surface of the sludge pusher 3 is polished, which can reduce the friction coefficient of sludge and slow down the adhesion of sludge.

[0035] Please see Figure 1 , Figure 3 and Figure 4 The sedimentation tank 1 is fixedly connected to both the front and back of a drive frame 4. Threaded rods 5 are rotatably connected between the inner bottom walls of the two drive frames 4. Drive blocks 6 are threadedly connected to the bottom ends of the two threaded rods 5. The two drive blocks 6 are slidably connected to the drive frames 4 adjacent to them. Two U-shaped connecting rods 7 are fixedly connected to the surface of the two drive blocks 6. The two U-shaped connecting rods 7 are symmetrically arranged. The filter screen 2 and the sludge pusher 3 are fixedly connected to the two U-shaped connecting rods 7. Through the above settings, the filter screen 2 and the sludge pusher can automatically move upward. The bottom ends of the two threaded rods 5 are fixedly connected to the output end of an external motor. The external motor can provide power for the rotation of the threaded rods 5.

[0036] Please see Figure 1 , Figure 2 and Figure 3A slide plate 8 is provided on one side of the sedimentation tank 1. The bottom of the slide plate 8 is inclined downwards. The top of the slide plate 8 is fixedly connected to the bottom of one side of the sedimentation tank 1. The slide plate 8 enables the automatic discharge of stones and sludge. A set of support frames 9 is fixedly connected between the slide plate 8 and the sedimentation tank 1. The support frames 9 support the slide plate 8 and improve its stability. A vibrator 10 is fixedly installed at the bottom of the slide plate 8. The vibrator 10 prevents sludge from adhering to the slide plate 8 and facilitates the sludge to slide off the push block 3 into the slide plate 8.

[0037] Please see Figure 1 , Figure 2 and Figure 3 A second pipe 11 is fixedly connected to the bottom of one side of the sedimentation tank 1. The second pipe 11 facilitates the connection between the user and the external clear water pool. A first pipe 12 is fixedly connected to one side of the sedimentation tank 1. The first pipe 12 facilitates the connection between the user and the external clear water pool.

[0038] In this embodiment, a wastewater recycling device for building construction utilizes an inclined filter screen 2 to automatically roll and collect stones and foreign objects under gravity, effectively avoiding filter clogging caused by distributed accumulation, ensuring filtration efficiency, and reducing manual maintenance costs. The sliding connection design between the sludge pusher 3 and the sedimentation tank 1, combined with its upward movement on the inclined surface, not only scrapes the inner wall of the sedimentation tank 1 during the lifting and lowering process to prevent sludge from adhering, but also effectively pushes the bottom sludge upward. In conjunction with the sliding plate 8, it facilitates the discharge of sludge and stones. The vibrator 10, during the discharge of sludge and stones, causes the entire device to vibrate, facilitating the downward movement of sludge and stones and improving sludge removal and waste discharge efficiency.

[0039] The working principle of the above embodiment is as follows: First, construction wastewater is introduced into sedimentation tank 1 through an appropriate method. The filter screen 2 plays a crucial role the moment the wastewater enters sedimentation tank 1. Because one end of the filter screen 2 is tilted downwards, stones and larger foreign objects in the wastewater automatically roll off under gravity and concentrate at one end of the filter screen 2, preventing these substances from accumulating on the screen and effectively preventing clogging, thus ensuring smooth filtration of the wastewater. As the wastewater continues to flow in and settle, sludge gradually accumulates at the bottom of sedimentation tank 1. When cleaning is required, the sludge pusher 3, through its sliding connection design with sedimentation tank 1 and its connection with threaded rod 5... The linkage mechanism with the drive block 6 enables automatic upward movement under the drive of the motor. During the upward movement, the inclined design of the push block 3 allows it to scrape the inner wall of the sedimentation tank 1, effectively preventing the adhesion of sludge. At the same time, the push block 3 also pushes the bottom sludge upward to prepare for subsequent sludge discharge. First, the left end of the filter screen 2 and the top of the slide plate 8 are on the same reference plane. The vibrator 10 is started, and the stone falls out of the slide plate 8 under the influence of gravity and vibration. Then, the drive motor continues to drive the threaded rod 5 to rotate, and the push block 3 and the filter screen 2 are at the same height, so that the sludge can be discharged again, which effectively improves the sludge discharge efficiency and reduces the labor intensity of workers.
