[0002] With the rapid development of the construction industry, a large amount of waste slurry water and waste residues are generated during the production of ready-mixed concrete. These waste slurry waters mainly come from the cleaning processes of mixing equipment, transport tank trucks, and concrete pump trucks, and contain the main components of concrete such as stones, sand, and cement slurry. If these waste slurry waters are directly discharged, it will not only waste water resources but also cause serious environmental pollution. Therefore, realizing the recycling and reuse of waste slurry water and reducing wastewater discharge conforms to the concept of green environmental protection and is of great significance for implementing the sustainable development strategy.

[0003] Currently, the recycling technologies of waste slurry water mainly include three aspects: sand and gravel separation, pretreatment of waste slurry water, and reuse of waste slurry water and waste residues. The sand and gravel separation technology separates stones and coarse sand in the residual concrete through a sand and gravel separator, and the remaining slurry water flows into a sedimentation tank. Through a three-stage sedimentation method, the slurry water that is basically clear after the third-stage sedimentation is used for flushing the site and dust suppression within the production plant.

[0034] During use, by starting the stirring motor 15, the worm 14 can be driven to mesh with the worm gear 13, and the worm gear 13 drives the inverted T-shaped mounting shaft 8 to rotate. At the same time, the two stirring rods 9 are driven to revolve around the inverted T-shaped mounting shaft 8, and the wastewater collected inside the water storage tank 2 is stirred evenly, so that the solid substances in the wastewater inside the water storage tank 2 are evenly distributed, thereby improving the utilization efficiency of the wastewater in concrete mixing and the quality of concrete.

[0035] Refer to Figure 1 - Figure 3 The transmission assembly includes a transmission gear ring 16 fixedly connected inside the water storage tank 2. A transmission gear 17 meshing with the transmission gear ring 16 is fixedly connected to the top of the stirring rod 9.

[0036] During use, when the inverted T-shaped mounting shaft 8 is started to drive the two stirring rods 9 to revolve along the inside of the water storage tank 2, the stirring rods 9 drive the transmission gears 17 to mesh with the transmission gear ring 16, and the transmission gears 17 drive the stirring rods 9 to rotate, so that the stirring rods 9 revolve around the inverted T-shaped mounting shaft 8 as the center and rotate at the same time, effectively improving the stirring efficiency of the stirring rods 9 for the wastewater inside the water storage tank 2 and further improving the uniformity of the distribution of solid substances in the wastewater.

[0037] Refer to Figure 2 - Figure 4 One end of the inverted T-shaped mounting shaft 8 is fixedly connected with a hanging rod 18, and the hanging rod 18 is attached to the inclined surface of the inwardly inclined ring platform 10.

[0038] During use, when the driving assembly is started to drive the inverted T-shaped mounting shaft 8 to rotate, the inverted T-shaped mounting shaft 8 drives the hanging rod 18 to rotate along the inclined surface of the inwardly inclined ring platform 10 and scrape the foreign objects adhered to the inclined surface of the inwardly inclined ring platform 10, so that the foreign objects are separated from the inclined surface of the inwardly inclined ring platform 10 and slide into the inside of the inclined bottom filter screen 11 for collection, effectively reducing the accumulation of foreign objects on the top of the inwardly inclined ring platform 10 and improving the practicability of the device.

[0039] Refer to Figure 2 and Figure 3 、 Figure 5 One end of the inverted T-shaped mounting shaft 8 is provided with a contact sliding groove 19, and a contact rod 20 is slidably connected inside the contact sliding groove 19. A contact assembly for pushing the contact rod 20 to fit with the inner bottom of the inclined bottom filter screen 11 is installed inside the inverted T-shaped mounting shaft 8; Among them, the contact assembly includes an inner groove 21 opened on the inner side of the contact sliding groove 19.

The inner spring 23 is installed inside the inner groove 21.

[0040] During use, when the inverted T-shaped mounting shaft 8 is driven to rotate, the inverted T-shaped mounting shaft 8 drives the contact rod 20 to rotate inside the inclined bottom filter screen 11. At the same time, by using the elastic characteristic of the inner spring 23, the inner spring 23 pushes the inner slider 22 to drive the contact rod 20 to move downward along the length direction of the contact sliding groove 19, and the contact rod 20 fits with the inner bottom of the inclined bottom filter screen 11 along the length direction of the contact sliding groove 19.

[0045] The implementation principle of the waste slurry water reuse method in this embodiment is as follows: First, a support grid 3 is set, so that the waste water containing mud generated by cleaning the mixer truck and the mixer passes through the support grid 3 and falls into the inside of the water storage tank 2 for collection and storage. At the same time, an inclined bottom filter screen 11 is set to filter the waste water falling into the inside of the water storage tank 2, separate the sand and gravel therein, and export the filtered sand and gravel through the discharge port 12 to wait for subsequent crushing and conversion into available aggregates; Then, by starting the stirring motor 15, the worm 14 can be driven to mesh with the worm gear 13, and the worm gear 13 drives the inverted T-shaped mounting shaft 8 to rotate. At the same time, two stirring rods 9 are driven to revolve around the inverted T-shaped mounting shaft 8, and the waste water collected inside the water storage tank 2 is evenly stirred. At the same time, the stirring rod 9 drives the transmission gear 17 to mesh with the transmission gear ring 16, and the transmission gear 17 drives the stirring rod 9 to rotate self - rotatably, effectively improving the stirring efficiency of the stirring rod 9 for the waste water inside the water storage tank 2, making the solid substances in the waste water inside the water storage tank 2 evenly distributed. At the same time, a solid concentration meter 7 is used to monitor the solid substance concentration of the waste water collected in the water storage tank 2 in real time; Next, when it is detected that the concentration of solid substances in the wastewater exceeds 10%, clean water is added to the inside of the water storage tank 2 through the externally connected water injection pipe 6 by a clean water pump for dilution, and the concentration is adjusted to below 10% to meet the requirements of concrete mixing. Then, the diluted wastewater is pumped out from the inside of the water storage tank 2 through the water extraction pump 4 and the water extraction pipe 5 at a mixing ratio of 30% to 70% and used in the concrete mixing process; Moreover, when driving the inverted T-shaped mounting shaft 8 to rotate, the inverted T-shaped mounting shaft 8 drives the hanging rod 18 to rotate along the inclined surface of the inwardly inclined ring platform 10, and scrapes the foreign matters adhered to the inclined surface of the inwardly inclined ring platform 10, so that the foreign matters are separated from the inclined surface of the inwardly inclined ring platform 10 and slide into the inside of the inclined bottom filter screen 11 for collection, effectively reducing the accumulation of foreign matters at the top of the inwardly inclined ring platform 10; At the same time, the inverted T-shaped mounting shaft 8 drives the contact rod 20 to rotate inside the inclined bottom filter screen 11. At the same time, by utilizing the elastic characteristics of the inner spring 23, the inner spring 23 pushes the inner slider 22 to drive the contact rod 20 to move downward along the length direction of the contact chute 19, and the contact rod 20 fits with the inner bottom of the inclined bottom filter screen 11 along the length direction of the contact chute 19. Thus, while the contact rod 20 rotates, it scrapes the gravel and other foreign matters collected inside the inclined bottom filter screen 11 to be separated and discharged from the inside of the water storage tank 2 along the guiding direction of the inclined bottom filter screen 11 and the discharge port 12.
