[0002] Waste liquid is the waste liquid discharged during the production process, such as cooling water, washing water or flushing water. These wastewaters contain a large amount of impurities, and direct discharge will cause pollution to the environment. Therefore, they need to be treated with caution when discharged.

[0003] After searching, China disclosed a waste liquid impurity stratification separation device with patent publication number CN220546619U on March 1, 2024. It is roughly described as including a separation tank, an overflow tank is provided at the top of the separation tank, a fixed block is provided on the outer wall of the overflow tank, an inlet pipe is installed on the top of the fixed block, a cross flow pipe is provided at one end of the water inlet pipe, several flat flow plates are provided at the bottom of the separation tank, several extension plates are provided at the top of the separation tank, a drain pipe is provided at the top of the overflow tank, a first sewage pipe is provided at the bottom of the overflow tank, and a second sewage pipe is provided at the bottom of the separation tank. Several extension plates are all inclined, and several flat flow plates are all inclined, and the top of each flat flow plate is arranged away from the cross flow pipe, and the bottom of each flat flow plate is arranged close to the cross flow pipe. The top of the overflow tank is higher than the top of the separation tank, and control valves are provided on the first sewage pipe and the second sewage pipe.

[0004] Although the above-mentioned prior art solution effectively improves the precipitation effect of impurities and improves the separation effect of impurities, the waste liquid in the device still has a certain impact force when flowing along the flat flow plate to the bottom of the separation tank, causing a small amount of impurities to float up, thereby reducing the impurity separation effect. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the utility model provides a waste liquid impurity stratification separation device to solve the problem proposed in the background technology that when the waste liquid flows along the flat flow plate to the bottom of the separation tank, there is still a certain impact force, which causes a small amount of impurities to float up, reducing the impurity separation effect.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a waste liquid impurity stratification separation device, comprising a separation tank, comprising a water inlet pipe, two matching primary guide plates fixedly connected to the inner wall of the separation tank, two secondary guide plates matching the primary guide plates fixedly connected to the inner wall of the separation tank, one end of the secondary guide plate is close to the inner wall of the separation tank, a fixing plate is fixedly connected to the outer wall of the separation tank near the top, a positioning piece is provided on the fixing plate, a first through hole is provided on the positioning piece, a supporting frame is fixedly connected to the inner wall of the separation tank, an isolation mesh plate is movably connected to the supporting frame, a second through hole is provided on the isolation mesh plate, the water inlet pipe is fixedly connected to the first through hole and the second through hole, one end of the water inlet pipe passes through the second through hole and is connected to a transverse pipe, and the two ends of the transverse pipe are respectively matched with the two primary guide plates.

[0009] By adopting the above technical solution, the waste liquid is introduced into the separation tank through the water inlet pipe and the transverse pipe. The waste liquid flows from the two ends of the transverse pipe to the two primary guide plates respectively, and then flows along the primary guide plates to the secondary guide plates, thereby gradually reducing the flow impact force of the waste liquid. Finally, the waste liquid flows along the inner wall of the separation tank to the bottom of the separation tank, thereby reducing the fluidity of the waste liquid. The small amount of floating impurities that still exist are blocked by the isolation mesh plate to prevent the impurities from floating upward, thereby shielding the impurities and improving the equipment's separation effect on impurities in the waste liquid.

[0010] Optionally, a sewage pipe is provided on the outer wall of the separation tank near the bottom end, and a drainage pipe is provided on the outer wall of the separation tank near the top end, and valves are provided on both the sewage pipe and the drainage pipe.

[0011] By adopting the above technical solution, the sewage pipe is used to discharge impurities settled at the bottom of the separation tank, and the drainage pipe is used to discharge waste liquid separated from impurities, thereby facilitating separate treatment of waste liquid and impurities.

[0012] Optionally, a rubber pad is fixedly connected to the bottom end of the isolation mesh plate, and the bottom end of the rubber pad is in close contact with the supporting frame.

[0013] By adopting the above technical solution, the rubber pad is used to improve the sealing between the isolation mesh plate and the supporting frame, preventing impurities from floating from the gap between the isolation mesh plate and the supporting frame to the top of the isolation mesh plate, thereby improving the impurity separation effect.

[0014] Optionally, a transparent observation window is provided on the separation tank.

[0015] By adopting the above technical solution, the transparent observation window is used to facilitate personnel to observe the separation status of waste liquid impurities and the remaining amount of waste liquid impurities inside the separation tank, thereby making it easier for staff to control water inlet and discharge.

[0016] Optionally, the positioning member and the fixing plate are connected by bolts.

[0017] By adopting the above technical solution, the bolts are turned and removed, and the positioning parts can be separated from the fixed plate. At this time, the water inlet pipe and the isolation mesh can be moved upward to remove the isolation mesh from the separation tank, so as to facilitate the cleaning of the isolation mesh and the interior of the separation tank, thereby facilitating the subsequent use of the equipment.

[0018] (3) Beneficial effects

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] 1. The waste liquid impurity stratification separation device introduces the waste liquid into the separation tank through the water inlet pipe and the transverse pipe. The waste liquid flows from the two ends of the transverse pipe to the two primary guide plates respectively, and then flows along the primary guide plates to the secondary guide plates, thereby gradually reducing the flow impact force of the waste liquid. Finally, the waste liquid flows along the inner wall of the separation tank to the bottom of the separation tank, thereby reducing the fluidity of the waste liquid. The small amount of floating impurities that still exist are blocked by the isolation mesh plate to prevent the impurities from floating upward, thereby shielding the impurities and improving the equipment's separation effect on impurities in the waste liquid.
