Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, specifically to a wastewater recycling device for construction. Background Technology

[0002] During the construction of basements in large-scale building projects, a large amount of sewage and wastewater is often generated, including rainwater, groundwater seepage, concrete mixing and cleaning wastewater. Construction wastewater may contain some solid debris such as cement, sand, gravel and metal.

[0003] Chinese Patent Publication No. CN220951488U discloses a construction wastewater recycling device, comprising: a treatment tank, with an inlet pipe fixedly installed at the upper end of one side of the treatment tank and a drain pipe fixedly installed at the lower end of one side of the treatment tank; and a filter plate fixedly installed inside the treatment tank on one side. This invention allows wastewater to be discharged into the treatment tank through the inlet pipe. After entering the treatment tank, the wastewater passes through the filter plate to filter out silt or gravel, thus achieving the effect of filtering and recycling silt or gravel, saving building materials or resources. Furthermore, the filtered wastewater is stored in the treatment tank, and flocculant is poured into the feeding assembly, allowing the flocculant to be injected into the treatment tank, causing impurities in the wastewater to settle at the bottom of the treatment tank, thus achieving the advantage of further filtration of the wastewater.

[0004] The aforementioned device filters mud or gravel through a filter plate, allowing the filtered mud or gravel to be discharged. However, during the filtration process, some fine sand and gravel can easily clog the filter holes inside the filter plate, thereby slowing down the flow rate of wastewater and reducing the overall wastewater filtration efficiency. Utility Model Content

[0005] To address the aforementioned problems, a wastewater recycling device for construction is provided. A rotating turntable drives one end of a connecting block to rotate, while the other end of the connecting block presses against a moving plate, further moving the moving plate. The moving plate then moves a top block, which in turn presses against another top block. The top block then drives a pushing block and a top plate towards a filter plate. A pin on the top of the top plate pushes out fine sand and gravel from the filter holes, preventing these particles from affecting the wastewater filtration efficiency.

[0006] To address the problems of existing technologies, this utility model provides a wastewater recycling device for construction, including a filter box. The top of the filter box is connected to an inlet hopper for discharging wastewater. Inside the filter box, there is a filter plate for filtering sand and gravel. A top plate is movably installed inside the filter box. The top of the top plate is provided with multiple pins for squeezing the filter holes inside the filter plate. The top plate has multiple through holes for wastewater leakage. The outer wall of the filter box near the filter plate is connected to a discharge frame for discharging sand and gravel. The other side wall of the filter box is connected to a drain pipe for draining water.

[0007] Preferably, the top of the filter box is connected to a feed hopper for storing flocculants.

[0008] Preferably, a drive motor is provided on the top of the filter box, and a stirring rod is provided on the output shaft of the drive motor through a coupling. A sealing plate for sealing the discharge end of the feed hopper is provided on the outside of the stirring rod, and a turntable is provided on the bottom of the stirring rod.

[0009] Preferably, a connecting block is rotatably disposed on the bottom periphery of the turntable, a movable plate is rotatably disposed on one end of the connecting block, a top block is rotatably disposed on the top of the movable plate, a pushing block is rotatably disposed on one end of the top block, and one end of the pushing block is connected to the bottom of the top plate.

[0010] Preferably, a symmetrical limiting telescopic rod is provided on one inner wall of the filter box, and the telescopic end of the limiting telescopic rod is connected to the side wall of the moving plate.

[0011] Preferably, symmetrical limiting blocks are provided on both outer walls of the top plate, and limiting grooves for the moving of the limiting blocks are provided on the inner wall of the filter box.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. The rotating turntable can drive one end of the connecting block to rotate, while the other end of the connecting block will squeeze the moving plate, further driving the moving plate to move. The moving plate drives the top block to move, and the top block will squeeze the top block when it moves. The top block drives the pushing block and the top plate to move towards the filter plate. The top pin on the top plate can push out the fine sand and gravel in the filter holes of the filter plate, preventing these sand and gravel from affecting the filtration efficiency of wastewater.

[0014] 2. The drive motor drives the stirring rod to rotate, and the sealing block outside the stirring rod also rotates, thus moving away from the discharge end of the feed hopper. At this time, the flocculant inside the feed hopper will fall into the filter box through the discharge end. The flocculant can be used to purify the filtered wastewater, and the rotation of the stirring rod can make the wastewater and flocculant mix better, promoting full contact and reaction between the flocculant and the wastewater.

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A wastewater recycling device for construction includes a filter box 1. The top of the filter box 1 is connected to an inlet hopper 4 for discharging wastewater. The filter box 1 is equipped with a filter plate 9 for filtering sand and gravel. A top plate 16 is movably installed inside the filter box 1. The top of the top plate 16 is provided with multiple top pins 17 for squeezing the filter holes inside the filter plate 9. The top plate 16 has multiple through holes for wastewater leakage. A discharge frame 5 for discharging sand and gravel is connected to the outer wall of the filter box 1 near the filter plate 9. A drain pipe 6 for draining water is connected to the other side wall of the filter box 1.

[0025] The filter plate 9 installed inside the filter box 1 can effectively filter sand and gravel in the wastewater. The filter plate 9 can effectively intercept and separate the sand and gravel. Subsequently, utilizing the inclined design of the filter plate 9, the filtered sand and gravel can smoothly slide into the discharge frame 5 and finally be discharged through the discharge frame 5.

[0026] like Figure 2 As shown, the top of the filter box 1 is connected to a feed hopper 3 for storing flocculants.

[0027] By using flocculants, we can effectively purify wastewater to improve water quality. Flocculants work by compressing the double electric layer, adsorption bridging, and netting and sweeping, causing suspended particles in wastewater to aggregate into larger flocs, thereby accelerating particle sedimentation, achieving solid-liquid separation, and making the wastewater clear.

[0028] like Figure 2 and Figure 4 As shown, a drive motor 2 is installed on the top of the filter box 1. A stirring rod 7 is installed on the output shaft of the drive motor 2 through a coupling. A sealing plate 8 for sealing the discharge end of the feed hopper 3 is installed on the outside of the stirring rod 7. A turntable 10 is installed at the bottom of the stirring rod 7.

[0029] Rotating the stirring rod 7 allows the wastewater and flocculant to mix better, promoting full contact and reaction between the flocculant and the wastewater. At the same time, the rotation of the stirring rod 7 also drives the turntable 10 to rotate.

[0030] like Figure 3 and Figure 5 As shown, a connecting block 11 is rotatably arranged on the bottom periphery of the turntable 10, a movable plate 12 is rotatably arranged on one end of the connecting block 11, a top block 13 is rotatably arranged on the top of the movable plate 12, a pushing block 14 is rotatably arranged on one end of the top block 13, and one end of the pushing block 14 is connected to the bottom of the top plate 16.

[0031] The rotating turntable 10 can drive one end of the connecting block 11 to rotate, while the other end of the connecting block 11 will press the moving plate 12, further driving the moving plate 12 to move. The moving plate 12 drives the top block 13 to move. When the top block 13 moves, it will press the top block 13. The top block 13 drives the pushing block 14 and the top plate 16 to move towards the filter plate 9. The top pin 17 on the top of the top plate 16 can push out the fine sand and gravel in the filter holes of the filter plate 9, preventing these sand and gravel from affecting the filtration efficiency of wastewater.

[0032] like Figure 2 and Figure 5 As shown, a symmetrical limiting telescopic rod 15 is provided on one inner wall of the filter box 1, and the telescopic end of the limiting telescopic rod 15 is connected to the side wall of the moving plate 12.

[0033] The limiting telescopic rod 15 prevents the moving plate 12 from shifting position during movement.

[0034] like Figure 2 and Figure 3 As shown, symmetrical limiting blocks 18 are provided on both outer walls of the top plate 16, and limiting grooves for the moving of the limiting blocks 18 are provided on the inner wall of the filter box 1.

[0035] By sliding the limiting block 18 within the limiting groove, the top pin 17 at the top of the top plate 16 can be accurately inserted into the filter hole inside the filter plate 9, thereby pushing out the sand and gravel inside the filter hole.

[0036] Working Principle: When wastewater from a construction site needs to be filtered, it is first discharged into the inlet hopper 4 via external equipment. This wastewater then enters the filter box 1 through the inlet hopper 4. The filter plate 9 inside the filter box 1 filters out the sand and gravel in the wastewater. The inclined surface of the filter plate 9 then discharges the filtered sand and gravel through the discharge frame 5. Simultaneously, the drive motor 2 is activated, causing the stirring rod 7 to rotate. The sealing block outside the stirring rod 7 also rotates, moving away from the discharge end of the inlet hopper 3. At this point, the flocculant inside the inlet hopper 3 falls into the filter box 1 through the discharge end. The flocculant purifies the filtered wastewater, and the rotation of the stirring rod 7 allows for better mixing of the wastewater and flocculant, promoting flocculation. The coagulant and wastewater come into full contact and react. The rotating rod 7 also drives the turntable 10 to rotate. The rotating turntable 10 drives one end of the connecting block 11 to rotate, and the other end of the connecting block 11 will squeeze the moving plate 12, further driving the moving plate 12 to move. The moving moving plate 12 drives the top block 13 to move. When the top block 13 moves, it squeezes the top block 13. The top block 13 drives the pushing block 14 and the top plate 16 to move towards the filter plate 9. The top pin 17 on the top of the top plate 16 can push out the fine sand and gravel in the filter holes of the filter plate 9, preventing these sand and gravel from affecting the filtration efficiency of the wastewater. The turntable 10 drives the connecting block 11 to move back and forth, which can intermittently clean the sand and gravel inside the filter holes of the filter plate 9.
