[0007] The sealing mechanism includes a plug, the plug is slidably disposed on the top of the drain pipe one, a plurality of through water outlets are formed in the circumferential outer wall of the plug, and the plurality of water outlets are located below the top inner wall of the plug. The circumferential outer wall of the plug is fixedly connected with a buoyancy block, the buoyancy block is located above the water outlet, the top center of the plug is fixedly connected with a trapezoidal clamping block, and the top of the trapezoidal clamping block is fixedly connected with two limit blocks two on both sides.

A sliding groove is formed in one side of the connecting block. A control rod is slidably connected in the sliding groove. A same tension spring is fixedly connected between one side of the control rod and the inner wall of one side of the sliding groove. The control rod is slidably penetrated through the circumferential inner wall of the water storage bucket. The control rod is tightly connected to the water storage bucket.

[0014] Working principle: In this application, when people need to treat the wastewater generated by viscose fiber production, they first pour the wastewater into the water storage barrel, then add coagulant into the water storage barrel and stir it. After the stirring is completed, let it stand until the suspended matter, colloidal substances, etc. form flocs and settle down, and then pull the handle to drive the operating rod to move outward. When the trapezoidal slot opened at the bottom of the operating rod moves to above the trapezoidal block, the plug moves upward under the combined action of the buoyancy of the buoyancy block and the elastic force of the spring, and then the plug pushes the top trapezoidal block into the trapezoidal slot until the limit block 2 on the top of the trapezoidal block is engaged between the two limit blocks 1 to complete the fixation of the operating rod. At this time, the upper layer of wastewater after standing and settling will enter the drain pipe 1 through the water outlet opened on the outer wall of the plug's circumference and be discharged. During the drainage process, the auxiliary support of the spring on the plug can prevent the buoyancy block from being The influence of water flow causes the limit block 2 to disengage from the engagement of the limit block 1. As the water level drops, the buoyancy of the buoyancy block will also drop as the water level drops. When the buoyancy block is no longer in contact with the water surface, the elastic force of the spring is insufficient to support the automatic opening of the plug. The plug will drive the limit block 2 to disengage from the engagement of the limit block 1 through the trapezoidal block under the action of its own weight. Then the operating rod will move inward under the elastic force of the tension spring, and accelerate the plug downward through the trapezoidal slot and the inclined surface of the limit block 2 until the bottom of the operating rod contacts the top of the trapezoidal block. At this time, the sealing gasket inside the plug will close the drain pipe 1, and then the next wastewater treatment can be started. When flocs formed by too much suspended matter, colloidal substances, etc. are precipitated in the water storage barrel, it is only necessary to open the water valve of the drain pipe 2 connected to the bottom of the water storage barrel to discharge the wastewater and sediment accumulated at the bottom of the water storage barrel together.

[0015] Beneficial effects: In the utility model, the sealing mechanism and the operating mechanism provided in the wastewater treatment device for viscose fiber production can achieve the effect of automatically closing the wastewater discharge port. Specifically, after the wastewater treatment is completed, as the water level drops, the buoyancy of the buoyancy block decreases, and the plug automatically drops under the action of its own weight and the tension spring, and tightly seals the drain pipe through the sealing gasket, effectively preventing wastewater leakage, avoiding the tedious steps of the operator manually closing the discharge port, reducing labor intensity, and at the same time reducing the risk of wastewater leakage caused by improper operation, thereby protecting the surrounding environment.

[0016] In the utility model, the wastewater treatment device for viscose fiber production can conveniently control the lifting and lowering of the plug and the opening and closing of the discharge port by pulling the handle to drive the operation lever to move. At the same time, the cooperation between the trapezoidal card slot and the trapezoidal card block and the locking action of the first limit block and the second limit block enable the plug to stay stably in the required position, thereby ensuring the continuity and efficiency of the wastewater treatment. In particular, in the continuous production process of viscose fiber, the device can operate continuously and efficiently, providing a strong guarantee for the stability and efficiency of the production line.

The control rod 7 is slidably penetrated through the circumferential inner wall of the water storage barrel 1, and is tightly connected with the water storage barrel 1 to prevent water leakage. The bottom of the control rod 7 is provided with a trapezoidal clamping groove 8, the trapezoidal clamping groove 8 is matched with the trapezoidal clamping block 14, for clamping the trapezoidal clamping block 14 when the plug 11 rises.
