A rotating rod is rotatably connected between the strips and the lower inner wall of the housing. Multiple stirring rods are equidistantly fixed to the outer circumference of the rotating rod. A drive motor is fixedly mounted on the lower surface of the housing, and the output shaft of the drive motor passes through the lower surface of the housing and is fixedly connected to the lower end of the rotating rod. A fan-blade rod located above the strips is rotatably connected to the right inner wall of the housing. A fan blade is fixedly connected to the left end of the fan-blade rod. A water inlet is located above the strips at the left end of the housing. This invention features a simple structure, ensuring thorough and uniform mixing of wastewater and chemicals during wastewater treatment, while preventing odorous gases from escaping through the chemical inlet and potentially harming workers. This significantly improves the practicality of the wastewater treatment device and is worthy of promotion.

[0004] However, the above-mentioned device still has some shortcomings in use. The concrete wastewater contains a lot of sand and gravel, which cannot be effectively filtered out. Direct discharge will still have an impact on the environment. The treatment effect on concrete wastewater is poor and not practical enough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment device for concrete production, which solves the problem that concrete wastewater contains a lot of sand and gravel, which cannot be effectively filtered out and removed. Direct discharge of such wastewater would still have an impact on the environment, resulting in poor treatment effect and impracticality.

[0006] This utility model provides the following technical solution: a wastewater treatment equipment for concrete production, including a base plate, a filter box and a treatment box are fixedly connected to the upper surface of the base plate, a water pump is fixedly connected to the upper surface of the base plate, the water inlet of the water pump is connected to the filter box, and the water outlet of the water pump is connected to the top of the treatment box.

[0007] Three sets of fixing plates are fixedly connected to the inner two side walls of the filter box. Each fixing plate has a movable groove on its surface. A vertical rod is slidably fitted inside each movable groove. A filter plate is fixedly installed between two sets of vertical rods. Three rotating rods are rotatably connected between the inner two side walls of the filter box. Two eccentric wheels are fixedly connected to the surface of each rotating rod. A spring is fitted at the lower end of each vertical rod.

[0008] The top of the treatment box has a dosing port, and a stirring rod is rotatably connected between the bottom wall and the top wall of the treatment box. Two rows of stirring plates are fixedly connected to the surface of the stirring rod. A drain pipe is connected to the side of the treatment box, and a valve is installed on the drain pipe.

[0009] Preferred technical solution 1: A first motor is fixedly connected to the upper surface of the processing box, and the output end of the first motor extends into the interior of the processing box and is fixedly connected to the stirring rod.

[0010] Preferred technical solution 2: Two connecting plates are fixedly connected to the side of the filter box, and a connecting rod is rotatably connected between the two connecting plates. Three first bevel gears are fixedly sleeved on the surface of the connecting rod. One end of each of the three rotating rods extends to the outside of the filter box and is fixedly connected to a second bevel gear. The three first bevel gears mesh with the three second bevel gears respectively.

[0011] Preferred technical solution three: A second motor is fixedly connected to the upper surface of the connecting plate located above, and the output end of the second motor passes through the connected connecting plate and is fixedly connected to the connecting rod.

[0012] Preferred technical solution four: The filter box has three discharge ports on its side, and the upper surface of the bottom plate has a placement groove, in which a collection box is placed.

[0013] Preferred technical solution five: the filter holes of the three filter plates decrease in size from top to bottom, and each of the stirring plates has multiple through holes on its surface.

[0014] Compared with existing technologies, this utility model provides a wastewater treatment device for concrete production, which has the following beneficial effects: During use, wastewater is poured into the filter box and falls onto the filter plates above. It then passes through three filter plates in sequence for filtration, removing particles such as stones and sand. During the filtration process, the rotation of a second motor drives the connecting rod and three first bevel gears to rotate, which in turn drives three second bevel gears and three rotating rods to rotate. This causes the eccentric wheel to continuously strike the edges of the filter plates, resulting in continuous up-and-down vibration of the three filter plates under the elastic force of springs and the action of the eccentric wheel, thus improving the filtration effect. Simultaneously, vibration allows solid particles to flow along the filter plate to the discharge port and be discharged into the collection tank, preventing filter plate clogging. After wastewater filtration is complete, it is pumped into the treatment tank, where treatment agents are added through the dosing port. The rotation of the first motor drives the stirring rod and stirring plate to fully mix the wastewater and agents, allowing them to react. The treated wastewater can then be discharged through the drain pipe. This equipment can perform multiple, multi-stage filtration of wastewater, resulting in better filtration and effectively preventing filter plate clogging, ensuring filtration efficiency and effectively treating wastewater.

[0020] Example 1: A wastewater treatment device for concrete production includes a base plate 1, a filter box 2 and a treatment box 3 are fixedly connected to the upper surface of the base plate 1, a water pump 4 is fixedly connected to the upper surface of the base plate 1, the inlet end of the water pump 4 is connected to the filter box 2, and the outlet end of the water pump 4 is connected to the top of the treatment box 3.

[0021] Three sets of fixed plates 5 are fixedly connected to the inner two side walls of the filter box 2. Each fixed plate 5 has a movable groove 6 on its surface. A vertical rod 7 is slidably fitted inside each movable groove 6. Filter plates 8 are fixedly installed between the corresponding two sets of vertical rods 7. Three rotating rods 9 are rotatably connected between the inner two side walls of the filter box 2. Two eccentric wheels 10 are fixedly connected to the surface of each rotating rod 9. A spring 21 is fitted at the lower end of each vertical rod 7.

[0022] The top of the treatment box 3 is provided with a dosing port 11. A stirring rod 12 is rotatably connected between the bottom wall and the top wall of the treatment box 3. Two rows of stirring plates 13 are fixedly connected to the surface of the stirring rod 12. A drain pipe is connected to the side of the treatment box 3, and a valve is provided on the drain pipe.

[0023] Example 2: The difference between this example and Example 1 is that a first motor 14 is fixedly connected to the upper surface of the processing box 3, and the output end of the first motor 14 extends into the interior of the processing box 3 and is fixedly connected to the stirring rod 12.

[0024] Example 3: The difference between this example and Example 1 is that two connecting plates 15 are fixedly connected to the side of the filter box 2, and a connecting rod 16 is rotatably connected between the two connecting plates 15. Three first bevel gears 17 are fixedly sleeved on the surface of the connecting rod 16. One end of each of the three rotating rods 9 extends to the outside of the filter box 2 and is fixedly connected to a second bevel gear 18. The three first bevel gears 17 mesh with the three second bevel gears 18 respectively.

[0025] Example 4: The difference between this example and Example 1 is that a second motor 19 is fixedly connected to the upper surface of the connecting plate 15 located above, and the output end of the second motor 19 passes through the connected connecting plate 15 and is fixedly connected to the connecting rod 16.

[0026] Example 5: The difference between this example and Example 1 is that the filter box 2 has three discharge ports on its side, and the upper surface of the bottom plate 1 has a placement groove, in which a collection box 20 is placed.

[0027] Example 6: The difference between this example and Example 1 is that the filter holes of the three filter plates 8 decrease in size from top to bottom, and multiple through holes are opened on the surface of each stirring plate 13.

[0028] In summary, this wastewater treatment equipment for concrete production involves feeding wastewater into the filter box 2, where it falls onto the filter plates 8 above. The wastewater is then filtered sequentially through three filter plates 8, removing particles such as stones and sand. During filtration, the rotation of the second motor 19 drives the connecting rod 16 and the three first bevel gears 17, which in turn drive the three second bevel gears 18 and the three rotating rods 9. This causes the eccentric wheel 10 to continuously strike the edges of the filter plates 8, resulting in repeated up-and-down vibrations of the three filter plates 8 under the elastic force of the spring 21 and the action of the eccentric wheel 10. This enhances the filtration effect and also allows for better filtration. Solid particles flow along the filter plate 8 to the discharge port and are discharged into the collection tank 20 to prevent the filter plate 8 from clogging. After the sewage is filtered, it is pumped into the treatment tank 3 by the water pump 4. Then, the treatment agent is added through the dosing port 11. The rotation of the first motor 14 drives the stirring rod 12 and the stirring plate 13 to fully mix the sewage and the agent, allowing them to react. The treated sewage can then be discharged through the drain pipe. This equipment can perform multiple and multi-stage filtration of sewage during use, resulting in better filtration effect. At the same time, it can effectively prevent the filter plate 8 from clogging, ensuring its filtration effect and effectively treating sewage.
