Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, specifically to an environmental engineering wastewater recycling device. Background Technology

[0002] Stone processing (such as cutting, beveling, and polishing) is mostly carried out outdoors or on construction sites using wet methods, which generates a large amount of wastewater containing stone powder. The core pollutant in this type of wastewater is micron-sized stone powder particles (mainly composed of calcium carbonate and silicon dioxide). These particles are small and easily suspended, and direct discharge will pollute the soil and water sources, resulting in a serious waste of water resources. At the same time, stone processing scenarios are characterized by dispersed work sites, the need for mobile deployment, the lack of fixed infrastructure, and the requirement for continuous wastewater treatment.

[0003] A search revealed that patent CN221522251U discloses an environmental engineering wastewater recycling device. Through a structure including a cam and a linkage block, a motor drives a stirring paddle to agitate the wastewater. Simultaneously, the rotating cam strikes the linkage block, causing flocculant inside the feed cylinder to be intermittently added to the wastewater. This causes colloids and suspended particles formed by insoluble substances in the wastewater to coagulate and be effectively filtered. The device also features wheels and a locking screw. Once the housing is pushed to a designated position, rotating the locking screw to a relaxed state allows the wheels to slide back into the support column, securing the housing at the work site for greater stability.

[0004] While the above solution is convenient for mobile use and can improve the uniformity of flocculant and wastewater mixing, during reagent use, the wastewater entering the shell needs to undergo a period of reaction and sedimentation after mixing with the flocculant before it can be discharged and utilized. During this process, wastewater cannot be injected into the shell, which will cause the wastewater treatment to stop and cannot operate continuously for a long time, and needs to be improved.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4In this embodiment of the utility model, an environmental engineering wastewater recycling device includes a frame 1. Multiple casters 2 are installed at the bottom of the frame 1. The casters 2 are heavy-duty swivel casters with locking function. A water tank 3 is fixedly installed on the top of the frame 1. The water tank 3 is made of FRP fiberglass, resistant to stone powder abrasion and outdoor rain. A central cylinder 4 is fixedly installed inside the water tank 3. Multiple partitions 5 are fixedly connected to the outer wall of the central cylinder 4 and the inner wall of the water tank 3. The partitions 5 divide the interior of the water tank 3 into 3-4 independent sedimentation tanks 6. The bottom of each sedimentation tank 6 is designed as a conical bucket structure and is equipped with a drain pipe 7. The drain outlet of the drain pipe 7 is fitted with a cap 8 to facilitate the rapid discharge of deposited stone powder sludge. A drain outlet is provided near the bottom of the outer wall of each sedimentation tank 6, and a drain valve 9 is installed on the drain outlet. The discharged purified water can be directly used for stone cutting and cooling. Each sedimentation tank 6 is equipped with a stirring mechanism. Above the central cylinder 4... A rotatable filter tank 16 is mounted, with a drain pipe 17 installed at the bottom center of the filter tank 16. Multiple fan-shaped stainless steel filter boxes 19 are arranged circumferentially within the filter tank 16, with a filter box aperture of 10-15mm, for secondary interception of large stone fragments and metal shavings. Hooks 20 are fixedly installed on the outer wall of each fan-shaped stainless steel filter box 19, and these hooks 20 are hung on the outer edge of the filter tank 16, facilitating disassembly and cleaning of the fan-shaped stainless steel filter boxes 19. A slurry pump 10 is fixedly installed on the outer wall of the water tank 3. The pump body impeller is made of high chromium alloy material, which is suitable for stone powder flushing. A hose 11 is fixedly installed at the water inlet end of the slurry pump 10, and a stainless steel filter cartridge 12 is installed at the water inlet end of the hose 11. The filter cartridge has a hole diameter of 15-25mm to initially intercept large particles of impurities. A water delivery pipe 18 is fixedly installed at the water outlet end of the slurry pump 10, and the water delivery pipe 18 is fixedly connected to the water tank 3 for transporting the pretreated wastewater to the filter tank 16.

[0021] By adopting the above-mentioned scheme, in use, after the inlet end of the hose 11 is inserted into the sewage collection tank, the slurry pump 10 is started. The sewage is then initially filtered by the stainless steel filter cartridge 12 and discharged into the filter tank 16 through the water supply pipe 18. The corresponding sector-shaped stainless steel filter box 19 is then used for secondary filtration of the sewage. The filtered sewage is discharged into a sedimentation tank 6 through the drain pipe 17. By adding flocculant to the sedimentation tank 6 and starting the stirring mechanism, the sewage and flocculant can be fully mixed. When the sewage level in the sedimentation tank 6 reaches a certain height, the filter tank 16 is rotated on the central cylinder 4, which moves the outlet of the drain pipe 17 to the top of the next sedimentation tank 6 to inject water into the next sedimentation tank 6. The other two sedimentation tanks that have been injected with water can undergo sedimentation during this process or discharge the sedimented sewage for reuse, so as to achieve uninterrupted sewage recycling and treatment. The effect is good, and it is convenient to clean the sector-shaped stainless steel filter box 19 that is not directly below the outlet of the water supply pipe 17.

[0022] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, a frame 13 is fixedly installed on the top of the central cylinder 4, a speed reduction stepper motor 14 is fixedly installed inside the frame 13, a tray 15 is rotatably connected to the top of the frame 13 through a turntable bearing, the top of the tray 15 is fixedly connected to the filter tank 16 through a bracket, the speed reduction stepper motor 14 is fixedly installed inside the frame 13, and the output shaft of the speed reduction stepper motor 14 is fixedly connected to the tray 15.

[0023] By starting the deceleration stepper motor 14, the tray 15 can be driven to rotate, thereby driving the filter tank 16 and the drain pipe 17 to rotate, so as to facilitate the filling of water into different sedimentation tanks 6.

[0024] Specific combination Figure 2-4 In one embodiment of this utility model, the stirring mechanism includes a mounting frame 21 fixedly installed in the top opening of the sedimentation tank 6. A stirring motor 22 is fixedly installed on the mounting frame 21. The output shaft of the stirring motor 22 is fixedly connected to a stirring head 23 through a coupling. When the stirring motor 22 is started, the stirring head 23 is driven to rotate to stir the sewage in the sedimentation tank 6, so that the sewage can be quickly mixed with the flocculant. The stirring motor 22 is a dual-speed motor with a power of 0.37-1.5kW, which is compatible with outdoor generator power supply. The stirring head rotates at 150-200rpm during the PAC addition stage and at 30-50rpm during the PAM addition stage to ensure floc formation and stability.

[0025] Specific combination Figure 2 In one embodiment of this utility model, each sedimentation tank 6 is equipped with a level switch 24. The level switch 24 is located near the top opening of the sedimentation tank 6. A control box 25 is fixedly installed inside the frame 1. The level switch 24 is a side-mounted float switch with a flow guide to prevent stone powder from entangled with flocs. When the water level reaches the set height, the level switch 24 is triggered, causing the reduction stepper motor 14 to switch the sedimentation tank 6 to receive water, thus preventing the sedimentation tank 6 from overflowing. The control box 25 has a protection rating of P65 and a built-in PLC controller, which can link the slurry pump 10, the stirring motor 22, the reduction stepper motor 14, and the level switch 24 to realize automatic water injection, automatic stirring, and automatic switching functions, thereby reducing the labor intensity of workers.
