Description

Technical Field

[0001] This invention relates to the field of equipment technology for the environmentally friendly utilization of concrete wastewater, specifically a device for adjusting the solid content of concrete wastewater. Background Technology

[0002] The production and use of concrete generate a large amount of wastewater and waste materials. Directly discharging this wastewater and waste not only pollutes the environment and is environmentally unfriendly, but also wastes resources. Currently, sand and gravel separators can separate stones, coarse sand, and some fine sand from concrete wastewater, but the remaining wastewater contains a large amount of fine sand, stone powder, cement slurry, and other materials. These slurry components cause the solid content of the wastewater to exceed the applicable range, and its uncontrolled use will seriously affect the quality of concrete. Even if sedimentation or filtration methods are used to first precipitate the powdery materials from the wastewater, these sediments are difficult to treat effectively. Random and uncontrolled treatment of sediments will cause environmental pollution. Because there is currently no system or device that can reliably and accurately adjust the solid content of concrete wastewater, this problem remains unsolved.

[0003] For example, a multi-cylinder automatic treatment system for recycled concrete wastewater, disclosed in the prior art with publication number "CN116474464A", relates to the field of concrete wastewater reuse technology. It includes a water storage component and a treatment tank. When the water level in the previous mixing tank of the water storage component reaches a warning value, wastewater is transferred to the next mixing tank. The main treatment tank includes a hydrocyclone, a coarse sand treatment tank, and a fine sand treatment tank. The coarse sand treatment tank is equipped with a first regulating pump that pumps wastewater into the fine sand treatment tank, and the fine sand treatment tank is equipped with a second regulating pump that pumps wastewater into the coarse sand treatment tank. This device, by setting up multiple mixing tanks, transfers wastewater to the next mixing tank when the water level in the previous mixing tank is too high to continue holding wastewater, greatly reducing production time and costs. Furthermore, the hydrocyclone separates coarse and fine sand and sends them to the coarse and fine sand treatment tanks respectively for recycling, achieving the effects of saving water resources and targeted recycling of materials.

[0004] However, the aforementioned device still has some obvious shortcomings in its use: although the device can reuse concrete wastewater, it cannot detect the solid content in the wastewater and adjust the formulation accordingly. Since the solid content in the reused wastewater needs to be precisely controlled, too high or too low a solid content will affect the quality of the reused concrete. Therefore, how to formulate a device that meets user needs and provides a stable solid content in wastewater has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a device for adjusting the solid content of concrete wastewater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A concrete wastewater solids content adjustment device includes a mixing tank, a metering tank, a finished product water tank, a concrete wastewater collection tank, and a clean water tank.

[0008] The metering tank is connected to the concrete wastewater collection tank via a pipeline. The clear water tank and the metering tank are connected to the slurry mixing cylinder via a pipeline. The slurry mixing cylinder is connected to the finished water tank via a pipeline. The finished water tank is also equipped with a solid content detector to detect the solid content of the finished water in the finished water tank.

[0009] Weight sensors are installed on the slurry mixing tank, metering tank, finished product water tank, concrete wastewater collection tank and clean water tank;

[0010] Liquid is pumped between containers connected by pipelines by corresponding water pumps installed on each container.

[0011] Preferably, the bottom of the mixing tank is equipped with multiple weight sensors I to weigh the pumped wastewater, the precipitated slurry, and the clean water used to adjust the solids content. A water pump I is installed outside the mixing tank to pump the adjusted solids content wastewater into the finished product tank. The upper part of the mixing tank is also provided with a water inlet I, which is connected to the clean water tank through a pipeline I. A mixer I is also installed on the upper part of the mixing tank to agitate the solids content wastewater in the tank. The mixing tank is also provided with a discharge port on one side of the mixer I, which is connected to the metering tank through a drain pipe to receive the wastewater flowing in from the drain pipe. A pneumatic valve is also provided on the drain pipe.

[0012] Preferably, the bottom of the metering tank is equipped with multiple weight sensors II to weigh the wastewater pumped from the concrete wastewater collection tank.

[0013] Preferably, the metering tank is also provided with an overflow port I and a water inlet II. When the metering tank receives wastewater pumped in from the water inlet II, the wastewater exceeding the overflow port I flows back to the concrete wastewater collection tank, thereby ensuring that the wastewater in the metering tank is at a preset volume.

[0014] Preferably, a water pump II is installed outside the finished product water tank. The water pump II is connected to the outlet pipe, which pumps the wastewater with adjusted solid content into the concrete mixing plant for concrete production. A water pump III is also installed outside the finished product water tank. The water pump III pumps the finished product water stored in the tank to a solid content detector through the pipeline II at regular intervals for solid content detection. An inlet IV is opened at the top of the finished product water tank, which is connected to the water pump I through the pipeline III. A mixer II is installed above the finished product water tank to agitate the finished product water inside the tank.

[0015] Preferably, the solid content analyzer is further provided with a water inlet III at the top. The water inlet III is connected to a water pump III installed outside the finished product water tank via a pipe IV. The finished product water in the finished product water tank is pumped into the solid content analyzer through the pipe IV to form test water. Several weight sensors III are installed at the bottom of the solid content analyzer to weigh the test water pumped from the finished product water tank. The solid content analyzer is equipped with a water pump IV outside, which is connected to the finished product water tank via a pipe to pump the test water back into the finished product water tank. A stirrer III is installed at the top of the solid content analyzer to stir the liquid in the solid content analyzer.

[0016] Preferably, the finished product water tank has an inlet VI at its upper part, and the solid content detector also has an overflow port II at its upper part. The inlet VI and the overflow port II are connected by an overflow pipe II. When the finished product water level in the solid content detector exceeds the overflow port II, the test water above the overflow port II flows back into the finished product water tank through the overflow pipe II, thereby ensuring that the test water flowing into the solid content detector is at a preset volume.

[0017] Preferably, the concrete wastewater collection tank is equipped with a water pump V on its exterior. The water pump V pumps the concrete wastewater in the collection tank into a metering tank through a pipeline V. The upper part of the concrete wastewater collection tank has an inlet V, which is connected to the overflow outlet I through an overflow pipe I to receive the wastewater overflowing from the metering tank. The concrete wastewater collection tank is also equipped with a mixer IV, which agitates the wastewater in the tank.

[0018] Preferably, the clean water tank is equipped with a water pump VI, which is connected to the slurry mixing tank through pipeline I, thereby pumping clean water into the slurry mixing tank and reducing the solid content of the wastewater in the slurry mixing tank.

[0019] Preferably, the concrete wastewater solids content adjustment device further includes an electrical control box, which is responsible for controlling the operation of each electrical component and executing the procedure for adjusting the solids content of the wastewater.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention features a metering tank at the front end of the mixing cylinder, allowing for the metered pumping of concrete wastewater into the cylinder. This effectively adjusts the solid content of the wastewater, ensuring that the solid content is sufficient to guarantee the quality of subsequent concrete while enabling the reuse of the wastewater. Furthermore, the solid content of the finished product is tested again using a solids content analyzer after mixing, further ensuring the accuracy of the mixing process and improving the environmentally friendly utilization rate of resources while maintaining the quality of subsequent concrete production.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 The present invention provides a technical solution:

[0026] Example 1:

[0027] A concrete wastewater solids content adjustment device includes a mixing tank 1, a metering tank 7, a finished product water tank 13, a concrete wastewater collection tank 28, and a clean water tank 35.

[0028] The metering tank 7 is connected to the concrete wastewater collection tank 28 through a pipeline. The clear water tank 35 and the metering tank 7 are connected to the slurry mixing cylinder 1 through a pipeline. The slurry mixing cylinder 1 is connected to the finished water tank 13 through a pipeline. The finished water tank 13 is also equipped with a solid content detector 22 to detect the solid content of the finished water in the finished water tank 13.

[0029] Weight sensors are installed on the slurry mixing tank 1, the metering tank 7, the finished product water tank 13, the concrete wastewater collection tank 28, and the clean water tank 35.

[0030] Liquid is pumped between containers connected by pipelines by corresponding water pumps installed on each container.

[0031] In this embodiment, the concrete wastewater solids content adjustment device mainly includes a mixing tank 1, a metering tank 7, a finished product water tank 13, a concrete wastewater collection tank 28, and a clean water tank 35. The mixing tank 1 is used for mixing and adjusting the slurry. Multiple weight sensors I2 are installed at the bottom of the mixing tank 1 to weigh the pumped wastewater, the precipitated slurry, and the clean water used to adjust the solids content. Specifically, when mixing is required, the total weight of the mixing tank 1 is weighed using the weight sensors I2, and the weight of the precipitated slurry inside the tank is obtained by subtracting the weight of the mixing tank 1 itself. Then, clean water and wastewater are introduced sequentially, and the weight of the introduced clean water and wastewater is weighed. A water pump I3 is installed outside the mixing tank 1. The water pump I3 pumps the adjusted solids content wastewater... Water is pumped into the finished product tank 13. The upper part of the mixing tank 1 is also equipped with a water inlet I6, which is connected to the clear water tank 35 via pipe I37 for the introduction of clear water. A mixer I4 is also installed on the upper part of the mixing tank 1 to agitate the solids-content wastewater within the tank. A discharge port is also located on one side of the mixer I4, connected to the metering tank 7 via a drain pipe 10. The discharge port receives wastewater flowing in from the drain pipe 10. A pneumatic valve 9 is also installed on the drain pipe 10. Before entering the mixing tank 1, the wastewater first enters the metering tank 7 for weighing and pre-mixing before being introduced into the mixing tank 1, ensuring the accuracy of wastewater flow. For this purpose, multiple weight sensors II8 are installed at the bottom of the metering tank 7. The wastewater pumped into the concrete wastewater collection tank 28 is weighed. The metering tank 7 is also equipped with an overflow port I12 and an inlet II11. When the metering tank 7 receives wastewater pumped into it from the inlet II11, the wastewater exceeding the overflow port I12 flows back into the concrete wastewater collection tank 28, thus ensuring that the wastewater in the metering tank 7 is at a preset volume. The solid content wastewater, after being mixed by the mixing cylinder 1, is sent to the finished product tank 13 through pipe III5. A water pump II14 is installed outside the finished product tank 13, connected to the outlet pipe 17. The outlet pipe 17 pumps the mixed solid content wastewater into the concrete mixing tower for concrete production. A water pump III15 is also installed outside the finished product tank 13, and the water pump III15 pumps... The finished water stored in the finished water tank 13 is periodically pumped to the solids content analyzer 22 for solids content testing. The finished water tank 13 has an inlet IV 20 at its top, which is connected to the water pump I 3 via pipe III 5. A stirrer II 16 is installed above the finished water tank 13 to agitate the finished water within the tank. To ensure the solids content of the finished water in the finished water tank 13 remains within a reasonable range, the finished water in the tank needs to be tested periodically. Therefore, a solids content analyzer 22 is installed at the top of the finished water tank 13 to test the solids content of the finished water. Furthermore, since the solids content analyzer 22 operates intermittently, a quantitative tank 7 can also be connected to the solids content analyzer 22 via a water pump and water pipe.This allows for the detection of solid content in the wastewater within the quantitative tank 7. This design provides a basis for determining the volume of clean water introduced into the mixing tank 1, thereby ensuring the accuracy of the finished water prepared in the mixing tank 1. The tested wastewater is then returned to the quantitative tank 7 via a pipeline. The solid content analyzer 22 also has an inlet Ⅲ26 at its upper part. Inlet Ⅲ26 is connected to a water pump Ⅲ15 installed externally in the finished water tank 13 via pipeline Ⅳ19. The finished water from the finished water tank 13 is pumped into the solid content analyzer 22 through pipeline Ⅳ19 to form test water. Several weight sensors Ⅲ23 are installed at the bottom of the solid content analyzer 22 to weigh the test water pumped from the finished water tank 13. The solid content analyzer 22 is externally equipped with a water pump Ⅳ. 24. Water pump IV 24 is connected to the finished product water tank 13 via a pipeline, thereby pumping the tested water back into the finished product water tank 13. A stirrer III 25 is installed on the top of the solids content analyzer 22 to stir the liquid in the analyzer. The finished product water tank 13 has an inlet VI 21 at its upper part, and the solids content analyzer 22 also has an overflow port II 27 at its upper part. The inlet VI 21 and the overflow port II 27 are connected by an overflow pipe II 18. When the finished product water level in the solids content analyzer 22 exceeds the overflow port II 27, the tested water above the overflow port II 27 flows back into the finished product water tank 13 through the overflow pipe II 18, thus ensuring that the tested water flowing into the solids content analyzer 22 is within a preset volume.

[0032] Example 2:

[0033] The concrete wastewater collection tank 28 is equipped with a water pump V29 on its exterior. The water pump V29 pumps the concrete wastewater in the concrete wastewater collection tank 28 into the metering tank 7 through the pipeline V31. The concrete wastewater collection tank 28 has an inlet V33 at the top. The inlet V33 is connected to the overflow outlet I12 through the overflow pipe I32, thereby receiving the wastewater overflowing from the metering tank 7. The concrete wastewater collection tank 28 is also equipped with a mixer IV30, which is used to mix the wastewater in the tank.

[0034] A water pump VI 36 is installed in the clean water tank 35. The water pump VI 36 is connected to the slurry mixing tank 1 through the pipeline I 37, thereby pumping clean water into the slurry mixing tank 1 and reducing the solid content of the wastewater in the slurry mixing tank 1.

[0035] In this embodiment, the structure of the concrete wastewater collection tank 28 and the clean water tank 35 is further disclosed, and the pipeline configuration for their connection with the mixing tank 1 or the metering tank 7 is disclosed. Since this structure is common in the prior art, it will not be described in detail here.

[0036] Example 3:

[0037] The concrete wastewater solids content adjustment device also includes an electrical control box 34, which is responsible for controlling the operation of each electrical component and executing the procedure for adjusting the solids content of the wastewater.

[0038] In this embodiment, the water pump, mixer, weight sensor, pneumatic valve and solid content detector mentioned in the instruction manual are controlled by the electrical control box 34. The flow of clean water or wastewater is adjusted according to the solid content detected by the solid content detector, thereby making the device more intelligent, further reducing the number of operators and reducing the intensity of work, and ensuring the accuracy of wastewater solid content adjustment.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
