[0004] However, in the actual production process, when washing equipment with concrete waste such as mixing plants and mixer trucks, the mud and sand produced enter the first sedimentation tank. The mud and sand move to the second sedimentation tank due to gravity, but due to the slow movement speed, it will solidify in the first sedimentation tank, requiring workers to clean it up, which is very inconvenient. Summary of the invention

[0005] In view of this, the object of the present invention is to provide a concrete wastewater treatment system, which eliminates the manual cleaning process and improves production efficiency.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a concrete wastewater treatment system, including a slurry pool, a floating water pool, and a treatment pool, the slurry pool and the treatment pool are connected through a first water pump, the floating water pool is connected to the slurry pool through a second water pump, a first partition is provided between the slurry pool and the floating water pool, a first water guide hole is provided on the upper edge of the first partition, and also includes a cross plate and an activator tank, the slurry pool and the treatment pool are both fixed with the cross plate, a power motor is fixedly connected to the cross plate, a power shaft of the power motor is connected to a stirring paddle for stirring mud and sand, the activator tank is connected to the treatment pool through a main water pump, and the activator tank contains a silicate high-alkali waste slurry activation modifier.

At this time, the concentration of the silt in the raw slurry pool increases, the power motor is turned on, and the power shaft drives the stirring paddle to rotate, so that the silt is continuously stirred and not easy to solidify. After the concentration of the silt in the raw slurry pool reaches the specified value, the first water pump is turned on, and the silt is injected from the raw slurry pool into the treatment pool, the main water pump is turned on, and the silicate high-alkali waste slurry activation modifier is injected into the treatment pool to enhance the activity of the silt for reuse, and then the second water pump is turned on, and the silt in the paddle floating water pool is injected into the raw slurry pool, which greatly improves the production efficiency.

[0010] As a preferred solution of the present invention, a third water pump is connected between the clear water tank and the raw pulp tank.

[0011] To implement the above technical solution, in summer when the temperature is high, the third water pump is turned on to inject clean water in the clean water tank into the raw pulp tank, thereby reducing the concentration of sediment in the raw pulp tank to avoid excessively high concentration of sediment in the raw pulp tank.

[0013] To implement the above technical solution, when the power shaft rotates in the forward direction, the unidirectional structure limits the rotation of the drive ring. At this time, the power shaft drives the stirring paddle to rotate to continuously stir the mud and sand, which is not easy to solidify; when the power shaft rotates in the reverse direction, the drive ring rotates synchronously with the power shaft through the friction structure, and the reciprocating structure is started through the connecting belt. The reciprocating structure drives the push plate to move back and forth to push the mud and sand toward the first water pump.

[0014] As a preferred solution of the present invention, the friction structure includes a friction ring and a friction groove, the friction groove is opened on the inner wall of the driving ring, the inner wall of the friction ring is fixed on the outer wall of the power shaft, and the friction ring is embedded in the friction groove.

[0015] To implement the above technical solution, the power shaft drives the driving ring to rotate synchronously through the friction force between the friction ring and the inner wall of the friction groove.

[0016] As a preferred solution of the present invention, the one-way structure includes a ratchet, a clamping plate and a first elastic member, the ratchet is fixed on the outer wall of the driving ring and is coaxially arranged with the driving ring, a fixing rod is fixedly connected to the inner wall of the raw pulp pool, the clamping plate is rotatably connected to the fixing rod and is used to be embedded in the ratchet, and the two ends of the first elastic member are respectively connected to the clamping plate and the fixing rod.

[0017] To implement the above technical solution, when the power shaft rotates in the forward direction, the elastic force of the first elastic member causes the card plate to be embedded in the ratchet to limit the rotation of the ratchet, thereby limiting the rotation of the drive ring; when the power shaft rotates in the reverse direction, the ratchet pushes the card plate to move away from the ratchet, and the elastic force of the first elastic member causes the card plate to maintain contact with the outer wall of the ratchet.

[0018] As a preferred embodiment of the present invention, the reciprocating structure includes a rotating rod, a slide rail, a slide seat, a first limit block, a second limit block, a connecting shaft, a driving wheel, a second elastic member, a swing rod, a first fixed column, a second fixed column, a first convex column, a second convex column, a third convex column, and a fourth convex column. The rotating rod is rotatably connected to the inner wall of the raw pulp pool, the rotating rod is connected to the driving ring through the connecting belt, the slide rail is fixed to the inner wall of the raw pulp pool and is arranged parallel to the rotating rod, the slide seat is slidably connected to the slide rail, the connecting shaft is rotatably connected to the slide seat, the driving wheel is rotatably connected to the connecting shaft and conflicts with the rotating rod, the driving wheel is tilted on the rotating rod, and the first fixed column is fixed to the rotating rod through the connecting rod. On the connecting shaft, one end of the swing arm is rotatably connected to the connecting shaft, and the other end of the swing arm is used to contact with the first limit block or the second limit block, the second fixed column is fixed on the swing arm, and the two ends of the second elastic member are respectively connected to the first fixed column and the second fixed column, the first limit block and the second limit block are both fixed on the inner wall of the raw pulp pool and are respectively close to the two ends of the rotating rod, the push plate is connected to the sliding seat, and there is a gap between the two ends of the push plate and the inner wall of the raw pulp pool, the first boss, the second boss, the third boss, and the fourth boss are fixed on the sliding seat and are respectively located on both sides of the swing arm, the first boss and the second boss are used to contact with the side wall of the swing arm, and the third boss and the fourth boss are used to contact with the connecting rod.

[0019] To implement the above technical solution, the driving ring rotates the rotating rod through the connecting belt. Since the driving wheel is tilted on the rotating rod, the driving wheel drives the slide to move along the length direction of the slide rail. When the end of the swing rod conflicts with the first limit block, the first limit block pushes the swing rod to rotate. When the swing rod rotates through the connecting line formed by the first fixed column, the second fixed column, and the axis of the connecting shaft, the elastic force of the second elastic member causes the swing rod to conflict with the first convex column, and the first fixed column drives the connecting shaft to rotate, so that the connecting rod and the first fixed column are connected. When the three convex columns collide with each other, the connecting rod drives the connecting shaft to rotate, causing the driving wheel to turn, and under the joint action of the rotating rod and the driving wheel, the slide moves in the opposite direction along the slide rail; similarly, when the swing arm conflicts with the second limit block, the second limit block pushes the swing arm to rotate, and after the swing arm passes the connecting line, the swing arm conflicts with the second convex column. At this time, the slide can move forward along the slide rail. During the forward and reverse movement of the slide, the push plate moves synchronously with the slide to scrape the mud and sand toward the first water pump, thereby reducing the residual mud and sand in the raw slurry pool.

[0021] To implement the above technical solution, a threshold value is set for the concrete concentration sensor. When the concentration of the silt in the raw slurry pool reaches the threshold value, the first water pump is started to pump the silt into the treatment pool; when the concentration of the silt in the raw slurry pool is too low, the second water pump is started, and the silt in the floating water pool is pumped into the raw slurry pool to increase the concentration of the silt; when the concentration of the silt in the raw slurry pool is too high, the third water pump is started, and the clean water in the clean water pool is injected into the raw slurry pool to reduce the concentration of the silt, thereby realizing a fully automatic operation process.

[0022] As a preferred solution of the present invention, the raw pulp pool, the floating water pool and the clear water pool are all provided with guard plates, and the guard plates are provided with through holes.

DETAILED DESCRIPTION

[0027] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0028] A concrete wastewater treatment system includes a raw pulp pool 11, a floating water pool 12, and a treatment pool 13. The raw pulp pool 11 is connected to the treatment pool 13 through a first water pump 14, and the floating water pool 12 is connected to the raw pulp pool 11 through a second water pump 15. A first partition 21 is provided between the raw pulp pool 11 and the floating water pool 12, and a first water guide hole 22 is provided on the upper edge of the first partition 21. The floating water pool 12 is located between the raw pulp pool 11 and the clean water pool 16. A second partition 23 is provided between the floating water pool 12 and the clean water pool 16, and a second water guide hole 24 is provided on the second partition 23, and the height of the second water guide hole 24 is lower than the height of the first water guide hole 22.

[0029] A third water pump 17 is fixedly connected between the clear water tank 16 and the raw pulp tank 11 .

[0030] A horizontal plate 3 is fixed on both the raw pulp pool 11 and the treatment pool 13, and the horizontal plate 3 is located in the middle of the raw pulp pool 11 and the treatment pool 13. A vertically arranged power motor 31 is fixedly connected to the horizontal plate 3, and a power shaft 32 of the power motor 31 is fixedly connected to a stirring paddle 33 for stirring mud and sand, and a plurality of stirring paddles 33 are evenly distributed along the axis of the power shaft 32.

[0031] The activator tank 18 is connected to the treatment tank 13 through the main water pump 19, and the activator tank 18 contains a silicate high-alkali waste slurry activation modifier.

[0032] A concrete concentration sensor 4 is fixedly connected to the inner wall of the raw pulp tank 11 , and the concrete concentration sensor 4 is electrically connected to the first water pump 14 , the second water pump 15 , and the third water pump 17 .

[0033] When flushing the mixing tank, mixing plant, and mixing truck, the generated silt is poured into the raw slurry pool 11, and the silt will settle at the bottom of the raw slurry pool 11. As the amount of silt poured into the raw slurry pool 11 increases, the water in the silt floats on the upper layer due to its low density, so that most of the water and a small amount of silt enter the floating water pool 12 from the first water guide hole 22.

[0034] The amount of water and sediment in the floating pool 12 gradually increases, and water is injected from the second water guide hole 24 into the clean water pool 16 to obtain clean water. The clean water can be used to wash the mixer truck.

[0035] At this time, the concentration of the silt in the raw slurry pool 11 will gradually increase. The concentration of the silt in the raw slurry pool 11 is monitored by the concrete concentration sensor 4. When the concentration of the silt reaches a threshold value, the concrete concentration sensor 4 sends an electrical signal to the first water pump 14, and the first water pump 14 starts to pump the silt in the raw slurry pool 11 into the treatment pool 13.

[0036] The main water pump 19 is turned on, and the silicate high-alkali waste slurry activation modifier is injected into the treatment tank 13 through the main water pump 19. The silicate high-alkali waste slurry activation modifier makes the silt difficult to solidify, and then the silt can be injected into the finished product tank for reuse.

[0037] When the concentration of the silt in the raw pulp pool 11 decreases and reaches a threshold, the second water pump 15 is turned on to introduce the silt in the floating water pool 12 into the raw pulp pool 11 through the second water pump 15 .

[0038] In summer, water evaporates quickly, the water content in the raw pulp pool 11 is low, and the concentration of sediment is too high. When the concentration of sediment reaches a threshold, the third water pump 17 is turned on to inject clean water into the raw pulp pool 11 to reduce the concentration of sediment.

[0039] This process is repeated to achieve the reuse of silt, eliminating the need for filter press filtration and making all of it reusable, greatly improving resource utilization and significantly reducing resource waste.

[0040] The power motor 31 is a servo motor. When the power motor 31 is started and the power shaft 32 rotates rapidly in the forward direction, the stirring paddle 33 rotates rapidly to quickly stir the silt in the raw pulp pool 11 to prevent coagulation.

[0041] A driving ring 5 is rotatably connected to the power shaft 32 , a friction structure 6 is provided between the driving ring 5 and the power shaft 32 , and a one-way structure 7 for limiting the rotation of the driving ring 5 is provided between the driving ring 5 and the inner wall of the raw pulp pool 11 .

[0042] When the power shaft 32 rotates in the forward direction quickly, the one-way structure 7 restricts the rotation of the drive ring 5. When the power shaft 32 rotates in the reverse direction slowly, the friction structure 6 causes the drive ring 5 to rotate synchronously with the power shaft 32.

[0043] The friction structure 6 includes a friction ring 61 and a friction groove 62. The friction groove 62 is annular and is opened on the inner wall of the driving ring 5. The inner wall of the friction ring 61 is fixed to the outer wall of the power shaft 32, and the friction ring 61 is embedded in the friction groove 62. The friction ring 61 is made of carbon fiber reinforced composite material.

[0044] The one-way structure 7 includes a ratchet 71, a clamping plate 72 and a first elastic member 73. The ratchet 71 is fixed to the outer wall of the driving ring 5 and is coaxially arranged with the driving ring 5. A fixing rod is fixedly connected to the inner wall of the raw pulp pool 11, and the clamping plate 72 is rotatably connected to the fixing rod and is used to be embedded in the ratchet 71. The two ends of the first elastic member 73 are respectively connected to the clamping plate 72 and the fixing rod.

[0045] When the power shaft 32 rotates rapidly in the forward direction, the elastic force of the first elastic member 73 causes the clamping plate 72 to be embedded in the ratchet 71, and the drive ring 5 cannot rotate. When the power shaft 32 rotates slowly in the reverse direction, the ratchet 71 pushes the clamping plate 72 away from the ratchet 71, and the friction force of the friction ring 61 causes the power shaft 32 to drive the drive ring 5 to rotate synchronously.

[0046] A reciprocating structure 9 is provided on the side wall of the stock pool 11, and the driving ring 5 is connected to the reciprocating structure 9 via a connecting belt 81. A first bevel gear 82 is rotatably connected to the inner wall of the stock pool 11, and the first bevel gear 82 is meshed with a second bevel gear 83.

[0047] The reciprocating structure 9 includes a rotating rod 91, a slide rail 92, a slide seat 93, a first limit block 94, a second limit block 95, a connecting shaft 96, a driving wheel 97, a second elastic member 98, a swing rod 99, a first fixed column 991, a second fixed column 992, a first convex column 993, a second convex column 994, a third convex column 995, and a fourth convex column 996. The rotating rod 91 is rotatably connected to the inner wall of the raw pulp pool 11 and is fixedly connected to the second bevel gear 83. The rotating rod 91 and the second bevel gear 83 are coaxially arranged.

[0048] The slide rail 92 is fixed on the inner wall of the raw pulp pool 11 and is arranged parallel to the rotating rod 91. The rotating rod 91 and the slide rail 92 are arranged horizontally. The slide seat 93 is slidably connected to the slide rail 92. The connecting shaft 96 is rotatably connected to the slide seat 93, and the driving wheel 97 is rotatably connected to the connecting shaft 96 and contacts the rotating rod 91. The driving wheel 97 is tilted on the rotating rod 91. During the rotation of the rotating rod 91, the driving wheel 97 can drive the slide seat 93 to move along the length direction of the slide rail 92.

[0049] The first fixing column 991 is fixed to the connecting shaft 96 through a connecting rod, and the connecting rod is horizontally arranged along the radial direction of the connecting shaft 96. One end of the swing rod 99 is rotatably connected to the connecting shaft 96, and the other end of the swing rod 99 is used to abut against the first limit block 94 or the second limit block 95. The second fixing column 992 is fixed to the swing rod 99.

[0050] The two ends of the second elastic member 98 are respectively connected to the first fixed column 991 and the second fixed column 992, and the second elastic member 98 is a tension spring. The first limit block 94 and the second limit block 95 are both fixed on the inner wall of the raw pulp pool 11 and are respectively close to the two ends of the rotating rod 91. The push plate 102 is fixedly connected to the slide seat 93, and there is a gap between the two ends of the push plate 102 and the inner wall of the raw pulp pool 11. When the push plate 102 moves to the end close to the raw pulp pool 11, the overflowed mud and sand can flow from the gap to the front of the push plate 102. The push plate 102 is located below the stirring paddle 33.

[0051] The first protrusion 993, the second protrusion 994, the third protrusion 995, and the fourth protrusion 996 are fixed on the slide 93 and are respectively located on both sides of the swing rod 99. The first protrusion 993 and the second protrusion 994 are used to abut against the side wall of the swing rod 99. The third protrusion 995 and the fourth protrusion 996 are used to abut against the connecting rod.

[0052] When the end of the swing rod 99 conflicts with the first limit block 94, the first limit block 94 pushes the swing rod 99 to rotate. When the swing rod 99 rotates across the connecting line formed by the axis of the first fixed column 991, the second fixed column 992 and the connecting shaft 96, the elastic force of the second elastic member 98 causes the swing rod 99 to conflict with the first protruding column 993, and the first fixed column 991 drives the connecting shaft 96 to rotate, causing the connecting rod to conflict with the third protruding column 995, and the connecting rod drives the connecting shaft 96 to rotate, causing the driving wheel 97 to turn. Under the joint action of the rotating rod 91 and the driving wheel 97, the slide seat 93 moves in the opposite direction along the slide rail 92.

[0053] Similarly, when the swing rod 99 conflicts with the second limit block 95, the second limit block 95 pushes the swing rod 99 to rotate. After the swing rod 99 rotates across the connecting line, the swing rod 99 conflicts with the second protrusion 994. At this time, the slide 93 can move forward along the slide rail 92. During the forward and reverse reciprocating movement of the slide 93, the push plate 102 moves synchronously with the slide 93 to scrape the mud and sand toward the first water pump 14, thereby reducing the mud and sand residue in the raw slurry pool 11.

[0054] The raw pulp pool 11 , the floating water pool 12 and the clear water pool 16 are all provided with a guard plate 100 , and a through hole 101 is opened on the guard plate 100 .

[0055] Since the resistance of the mud and sand is large, if the push plate 102 moves quickly, it is easy to cause the push plate 102 to break, so the push plate 102 can only move slowly. If the stirring paddle 33 rotates slowly, it is easy to cause the mud and sand to solidify, so the stirring paddle 33 can only rotate quickly.

[0056] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
