[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-2 , a concrete mixing station sewage separation and recovery treatment device, comprising a recovery treatment pool 1 for collecting and storing concrete mixing station sewage, an inlet pipe 2 for sewage input is installed at the upper part of one side of the recovery treatment pool 1, and an outlet pipe 3 for sewage output is installed at the lower part of the other side of the recovery treatment pool 1, and a plurality of partition walls 4 are sequentially installed in the recovery treatment pool 1 from the side of the inlet pipe 2 to the side of the outlet pipe 3. The partition wall separates a plurality of separation recovery chambers 5 in the recovery treatment pool 1, and a diversion pipe 6 for connecting two adjacent separation recovery chambers 5 is installed at the lower part of the separation wall, so that the sewage input through the side of the inlet pipe 2, through the diversion effect of the diversion pipe 6, is overflowed and precipitated layer by layer through the separation recovery chamber 5 in the recovery treatment pool 1, so that solid matter in the sewage is intercepted, so that there is basically no solid matter in the sewage output from the outlet pipe 3, which is convenient for recycling and reuse. Of course, in order to better treat the sewage, the sewage in the separation recovery chamber 5 at the outlet pipe 3 can also be treated with chemical agents such as sewage treatment agents to meet the reuse requirements;

[0020] Preferably, the recovery treatment pool 1 and the separation recovery chamber 5 are both in the shape of a rectangular parallelepiped, and the volume of the separation recovery chamber 5 decreases from the side of the water inlet pipe 2 to the side of the water outlet pipe 3, so that the volume of the separation recovery chamber 5 close to the side of the water inlet pipe 2 is larger, which is convenient for better sedimentation of solid matter in the sewage;

[0021] In order to control and adjust the overflow of sewage, an overflow hose 7 is installed in the separation recovery chamber 5 near the water inlet pipe 2 in the two adjacent separation recovery chambers 5. One end of the overflow hose 7 is connected to the diversion pipe 6, and the other end of the overflow hose 7 is installed with a filter screen 8. A lifting rope 9 is also connected to the overflow hose 7 on the side of the filter screen 8, and a lifting device that cooperates with the lifting rope 9 is installed on the side of the recovery pool 1. Through the cooperation of the lifting device and the lifting rope 9, the height of the overflow hose 7 in the separation recovery chamber 5 can be adjusted, so that only the sewage higher than the overflow hose 7 can flow through the overflow hose 7 and the diversion pipe 6 to the next separation recovery chamber 5. At the same time, the filter screen 8 can also filter the sewage flowing into the overflow hose 7; in actual use, in order to increase the weight of the overflow hose 7, a counterweight block can be added to the overflow hose 7 at the filter screen 8, so that the overflow hose 7 can automatically sink when not being pulled by the lifting rope 9, which is convenient for adjusting the overflow hose 7;

[0022] Preferably, the filter screen 8 is an outwardly convex arc-shaped filter screen 8, which helps to prevent solid matter in the sewage from clogging the filter screen 8.

[0023] Specifically, the lifting equipment includes a lifting rod 10 vertically fixedly installed on the side of the recovery and treatment pool 1, and a plurality of lifting rings 11 are installed on the lifting rod 10 in sequence from top to bottom. A lifting hook 12 cooperating with the lifting ring 11 is connected to the lifting rope 9. The lifting hook 12 cooperates with the lifting rings 11 at different heights to adjust the lifting rope 9, and then adjust the height of the overflow hose 7 through the lifting rope 9.

[0024] In actual use, a flushing pipe 13 is connected between the bottoms of the two adjacent separation and recovery chambers 5, and a flushing control valve 14 is installed on the flushing pipe 13, so that the sewage in one separation and recovery chamber 5 can flow to the other separation and recovery chamber 5 by using the flushing pipe 13, so as to facilitate the flushing operation of the separation and recovery chamber 5. Generally, the sewage in the separation and recovery chamber 5 close to the outlet pipe 3 flows to the separation and recovery chamber 5 close to the inlet pipe 2, because after the sedimentation treatment operation process, the sewage in the separation and recovery chamber 5 close to the outlet pipe 3 is cleaner than the sewage in the separation and recovery chamber 5 close to the inlet pipe 2, which helps to ensure the flushing effect;

[0025] Secondly, in order to finally discharge the remaining sewage in the separation and recovery chamber 5, an emptying pipe 15 is connected to the bottom of the separation and recovery chamber 5 closest to the water inlet pipe 2, and an emptying control valve 16 is installed on the emptying pipe 15; of course, before the remaining sewage is finally discharged, sewage treatment operations are required to make it meet the discharge standards, or it can be discharged into the existing sewage treatment pipeline and mixed with other sewage before being discharged.

[0026] When in use, the sewage from the concrete mixing station is input into the recovery treatment pool through the water inlet pipe, first enters the first separation recovery chamber, and then enters the second separation recovery chamber through the overflow hose and the diversion pipe, and so on, enters the third separation recovery chamber... Generally, 3-5 separation recovery chambers are set, and finally output to the outside through the outlet pipe for recycling. During this period, due to the cooperation of the overflow hose and the filter net, the solid matter in the sewage is retained. At the same time, the height of the overflow hose and the filter net can be adjusted according to needs by using the pulling equipment and the pulling rope, so that there is basically no solid matter in the sewage output through the outlet pipe, which is convenient for recycling. In order to meet the reuse requirements, chemical agents such as sewage treatment agents can also be added for treatment;

[0027] During flushing, the sewage in the first separation and recovery chamber is first discharged, and then the sewage in the next separation and recovery chamber is successively input into the previous separation and recovery chamber to achieve the purpose of flushing. All discharged sewage can be discharged into the existing sewage treatment pipeline, mixed with other sewage and then discharged.
