Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology for recycled concrete, and in particular to a wastewater treatment device for recycled concrete processing. Background Technology

[0002] Recycled concrete is produced by recycling discarded concrete blocks after building demolition. The waste concrete blocks are crushed, washed, and graded to produce recycled aggregate. Other types of aggregate, cement, and water are then added to the recycled aggregate to create new concrete. Adding a certain proportion of high-strength lightweight aggregate, cement, and water to the recycled aggregate produces high-strength lightweight aggregate concrete. During the production of high-strength lightweight aggregate concrete, waste slurry is generated. To reduce environmental pollution and water waste, this waste slurry is usually recycled. However, current technologies for treating recycled concrete wastewater rely on natural filtration, which limits the filtration effect as the waste liquid passes through the filter plates, and the accumulated waste slurry tends to accumulate. Therefore, this paper proposes a wastewater treatment device for recycled concrete processing to address these issues. Utility Model Content

[0010] This utility model has the following beneficial effects:

[0011] 1. Compared with the prior art, this wastewater treatment device for recycled concrete processing, by setting up treatment components, causes the waste liquid in the separation tank to rotate rapidly when the drive mechanism starts working. Due to the centrifugal force, the waste liquid can better contact the filter holes, thereby facilitating the filtration treatment of waste liquid, and the separation capacity can be improved by centrifugal force separation.

[0012] 2. Compared with the prior art, this wastewater treatment device for recycled concrete processing, by setting up a bend and a ball, when the separation tank rotates rapidly, due to the centrifugal force, the ball in the active area is pressed tightly against the outside, that is, the ball and the inner wall of the limiting ring are in close contact, thereby preventing the waste liquid in the separation tank from entering the second fixed pipe through the bend during the separation process; after the separation tank stops rotating, the ball falls and no longer contacts the limiting ring. At this time, the residual waste liquid remaining in the separation tank enters the second fixed pipe through the through hole and is discharged through the waste liquid pipe. Therefore, this device can separate the treated waste liquid for separate discharge, which is conducive to the collection of different waste liquids and facilitates subsequent work.

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] Reference Figures 1-4 The present invention provides a wastewater treatment device for recycled concrete processing: including a wastewater treatment tank 1 and a drive mechanism 2. The drive mechanism 2 is prior art and will not be described in detail here. An inlet pipe 3 is fixedly connected to the top of the wastewater treatment tank 1, and a waste liquid pipe 4 and an outlet pipe 10 are fixedly connected to the bottom of the wastewater treatment tank 1. The drive mechanism 2 is set at the top of the wastewater treatment tank 1 and also includes a treatment component for solid-liquid separation of the wastewater entering the wastewater treatment tank 1. The treatment component is connected to the output end of the drive mechanism 2.

[0021] The processing assembly includes a separation tank 9, with several filter holes 19 on its side walls. A first fixed pipe 7 is fixedly connected to the separation tank 9, and a second connecting pipe 6 is rotatably connected to the end of the first fixed pipe 7 away from the separation tank 9. The second connecting pipe 6 is rotatably connected to the output end of the drive mechanism 2. A first connecting pipe 5, which communicates with the second connecting pipe 6, is fixedly connected to the inner end of the inlet pipe 3. The second connecting pipe 6 communicates with the inside of the separation tank 9 through the first fixed pipe 7. By setting up the processing assembly, since the separation tank is located inside the wastewater treatment tank 1, during operation, the mixed wastewater first enters the separation tank 9 through the inlet pipe 3 and the first connecting pipe 5. When the drive mechanism 2 starts working, the waste liquid in the separation tank 9 rotates rapidly. Due to the centrifugal force, the waste liquid can better contact the filter holes 19, thereby facilitating the filtration and treatment of the waste liquid.

[0022] The bottom of the separator 9 is fixedly connected to a second fixed pipe 8, which is rotatably connected to the waste liquid pipe 4 and is in communication with the waste liquid pipe 4. The second connecting pipe 6 is located between the output end of the drive mechanism 2 and the first fixed pipe 7. The output end of the drive mechanism 2 can drive the second connecting pipe 7 to rotate without being interfered with by the first connecting pipe 5. This connection structure is existing technology and will not be described in detail here.

[0023] The first fixed pipe 7 and the second fixed pipe 8 are both rotatably connected to the side walls of the fixed frame 18. The two fixed frames 18 are fixedly connected to the inside of the wastewater treatment tank 1. The two fixed frames 18 are located at the upper and lower ends of the treatment component, thereby supporting the treatment component.

[0024] A bend 11 and a fixing plate 16 are fixedly connected to the inner end of the second fixed pipe 8. A fixed limiting ring 12 is fixedly connected to the end of the bend 11 away from the second fixed pipe 8. An inlet 13 is provided inside the limiting ring 12. An active area 15 is provided between the bend 11 and the fixing plate 16. A ball 14 is placed in the active area 15. Several fixing brackets 18 are provided at the end of the fixing plate 16 near the ball 14. By setting up the bend 11 and the ball 14, when the separation tank 9 rotates rapidly, due to the centrifugal force, the ball 14 in the active area 15 will move freely. The sphere 14 is tightly attached to the inner wall of the limiting ring 12, thus preventing the waste liquid in the separation tank 9 from entering the second fixed pipe 8 through the bend 11 during the separation process. After the separation tank 9 stops rotating, the sphere 14 falls down and no longer contacts the limiting ring 12. At this time, the residual waste liquid remaining in the separation tank 9 enters the second fixed pipe 8 through the through hole 20 and is discharged through the waste liquid pipe 4. Therefore, this device can separate the treated waste liquid and discharge it separately, which is conducive to the collection of different waste liquids and facilitates subsequent work.

[0025] The fixed plate 16 is also provided with a notch 17 at one end near the ball 14. The notch 17 is adapted to the size of the ball 14. The second fixed pipe 8 is connected to the active area 15 through the fixed frame 18. The bottom center of the wastewater treatment tank 1 is recessed downward. By setting a bend pipe 11 and installing it in the center recess, the waste liquid in the separation tank 9 can more easily enter the second fixed pipe 8.

[0026] Working principle:

[0027] During operation, the inlet pipe 3 is first connected to the external waste liquid outlet, so that the mixed wastewater enters the separation tank 9 through the inlet pipe 3 and the first connecting pipe 5. When the drive mechanism 2 starts to work, the waste liquid in the separation tank 9 rotates rapidly. Due to the centrifugal force, the waste liquid can better contact the filter hole 19, thus facilitating the filtration and treatment of the waste liquid.

[0028] When the separator 9 rotates rapidly, the centrifugal force causes the spheres in the active area 15 to press tightly against each other, that is, the spheres 14 and the inner wall of the limiting ring 12 are in close contact, thereby preventing the waste liquid in the separator 9 from entering the second fixed pipe 8 through the bend 11 during the separation process. After the separator 9 stops rotating, the spheres 14 fall down and no longer contact the limiting ring 12. At this time, the residual waste liquid remaining in the separator 9 enters the second fixed pipe 8 through the through hole 20 and is discharged through the waste liquid pipe 4.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
