Detailed implementation manners

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer toFigures 1-4 , the present utility model provides an embodiment: a deep treatment device for coal chemical wastewater, which includes a mounting frame 1, and also includes a water drainage box 2. The upper end of the mounting frame 1 is fixedly installed with a filter pipe groove 3. Inside the filter pipe groove 3, there is a transmission shaft 4. On the surface of the transmission shaft 4, there are fixedly installed transmission blades 5. The right end of the filter pipe groove 3 is fixedly installed with a motor 6. The lower side of the surface of the filter pipe groove 3 is fixedly installed with a liquid outlet concentration box 7. Inside the liquid outlet concentration box 7 on the surface of the filter pipe groove 3, there is a sieve mesh 8. On the right side of the liquid outlet concentration box 7 on the surface of the filter pipe groove 3, there is an impurity discharge port 9. Inside the upper side of the water drainage box 2, there is a collection basket frame 10. At the lower end of the collection basket frame 10 inside the water drainage box 2, there is a wire basket 11 fixedly installed. The lower side of the left end of the water drainage box 2 is fixedly connected with a connecting pipe 12.

[0022] Please refer to Figures 1-2 , in this embodiment, the left end of the transmission shaft 4 is rotatably connected to the filter pipe groove 3. The upper side of the surface of the filter pipe groove 3 is fixedly connected with a liquid inlet pipe 13. The transmission blades 5 are designed in a spiral structure, and the transmission blades 5 are adapted to the filter pipe groove 3. The output end of the motor 6 extends into the filter pipe groove 3 and is fixedly connected to the transmission shaft 4. The output end of the motor 6 is rotatably connected to the filter pipe groove 3. By driving the transmission shaft 4 to rotate through the motor 6, the transmission blades 5 drive the coal slag impurities remaining inside the filter pipe groove 3 to move to the right until the coal slag impurities are concentrated and fall into the wire basket 11, avoiding the accumulation of coal slag impurities on the screening structure, which is beneficial to realizing the anti-blocking function of the deep treatment device for coal chemical wastewater.

[0023] Please refer to Figure 1 , Figure 3 and Figure 4 , in this embodiment, the water drainage box 2 is fixedly connected to the mounting frame 1. On the front and rear sides of the upper end of the collection basket frame 10, there are fixedly installed handles. The collection basket frame 10 is snap-connected to the water drainage box 2. On the front and rear sides of the upper end of the water drainage box 2, there are rotatably connected limit blocks 14. The lower end of the liquid outlet concentration box 7 is connected with a liquid outlet pipe 15. The end of the connecting pipe 12 far away from the water drainage box 2 is connected to the liquid outlet pipe 15. Through the mesh structure of the wire basket 11 and the certain space gap between the wire basket 11 and the water drainage box 2, it is convenient to drain the water carried on the surface of the coal slag impurities, and then input it into the liquid outlet pipe 15 again through the connecting pipe 12. At the same time, the coal slag impurities are uniformly collected by the wire basket 11 and separated from the main screening mechanism, which is beneficial to improving the convenience of cleaning the coal slag impurities.

[0024] When working, coal chemical industry wastewater is first input from the liquid inlet pipe 13, filtered by the sieve mesh 8, and concentrated and falls into the liquid outlet concentration box 7 and is discharged by the liquid outlet pipe 15, so that coal slag impurities are intercepted on the sieve mesh 8. The transmission shaft 4 is rotated by the motor 6, so that the transmission blades 5 drive the coal slag impurities remaining inside the filter pipe groove 3 to move to the right until the coal slag impurities are concentrated and fall into the wire basket 11, avoiding the accumulation of coal slag impurities on the screening structure. Through the mesh structure of the wire basket 11 and the certain space gap between it and the water drainage box 2, it is convenient to drain the water carried on the surface of the coal slag impurities, and cooperate with the connecting pipe 12 to input into the liquid outlet pipe 15 again. At the same time, the wire basket 11 is used to uniformly collect the coal slag impurities, which are separately set up from the main screening mechanism.

[0025] Through the above steps, the motor 6 drives the transmission blades 5 to rotate, so that the coal slag impurities are pushed towards the impurity discharge port 9 until the coal slag impurities are concentrated and fall into the wire basket 11, avoiding the accumulation of coal slag impurities on the screening structure, so as to solve the problem that as more and more coal slag impurities in the wastewater are intercepted by screening, the coal slag impurities accumulate on the screening structure and are likely to cause equipment blockage.
