DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a wastewater treatment device for chemical production safety includes a box body 1, a sliding frame 2, a filter screen 3, an electric push rod 4, a drain pipe 5, a valve 6, a mounting pipe 7, a rotating block 8, a spring 9, a mounting rod 10, a rotating frame 11 and a filter element 12. The sliding frame 2 is slidably connected in the box body 1, and the filter screen 3 is connected to the bottom of the sliding frame 2. The filter screen 3 contacts the inner wall of the box body 1. The electric push rod 4 is installed on both sides of the front and rear of the middle of the box body 1 by bolts. The telescopic rod of the electric push rod 4 is connected to the sliding frame 2. The lower front side of the box body 1 is connected to the drain pipe 5, and the valve 6 is installed on the drain pipe 5. The lower front side of the box body 1 is connected to the mounting pipe 7. The rotating block 8 is rotatably connected in the mounting pipe 7, and the front side of the rotating block 8 is connected to the spring 9. The front end of the spring 9 is connected to the mounting rod 10, and the front end of the mounting rod 10 is connected to the rotating frame 11. Five filter elements 12 are evenly spaced circumferentially installed on the rotating frame 11, and the front end of the drain pipe 5 extends into the filter element 12.

[0023] like Figure 2 As shown, it also includes a stirring rod 13 and a motor 14. The stirring rod 13 is rotatably connected to the middle of the upper part of the sliding frame 2. The stirring rod 13 is located in the box body 1. The motor 14 is installed in the middle of the top of the sliding frame 2 by bolts, and the output shaft of the motor 14 and the upper end of the stirring rod 13 are connected by a coupling.

[0024] like Figure 5 and Figure 6 As shown, it also includes a first baffle 15 and a second baffle 16. The first baffle 15 is connected to the left side of the top of the box body 1, and the second baffle 16 is connected to the right side of the top of the box body 1. The sliding frame 2 is located between the first baffle 15 and the second baffle 16.

[0025] like Figure 5 As shown, it also includes an electric guide rail 17 and a scraper 18. Two electric guide rails 17 are installed on the top of the first baffle 15 and the second baffle 16. The two electric guide rails 17 are symmetrically arranged front to back, and a scraper 18 is connected between the sliders on the two electric guide rails 17.

[0026] like Figure 5As shown, a collecting frame 19 is also included, and the upper right side of the box body 1 is connected to the collecting frame 19 by bolts.

[0027] like Figure 2 As shown, a sealing ring 20 is also included. The front end of the drain pipe 5 is connected to the sealing ring 20, and the sealing ring 20 is in contact with the inner wall of the filter element 12.

[0028] Initially, the spring 9 is in a stretched state, so the spring 9 can pull the filter element 12, so that the filter element 12 and the front end of the drain pipe 5 are in close contact to prevent wastewater leakage, and the sealing ring 20 can improve the sealing between the drain pipe 5 and the filter element 12. Then the staff pours the wastewater into the box body 1, and the filter screen 3 can filter the particles in the wastewater, thereby treating the wastewater, and then pour an appropriate amount of flocculant into the box body 1. The flocculant can make the small particles in the wastewater gather into large particles, so that the filter screen 3 can filter more particles. The output shaft of the motor 14 can drive the stirring rod 13 to rotate, and the stirring rod 13 can stir the flocculant and particles in the box body 1, so that the flocculant can fully contact with the particles, thereby better aggregating small particles. Then the staff controls the telescopic rod of the electric push rod 4 to extend, drives the sliding frame 2 to move upward, and the sliding frame 2 drives the filter screen 3 to move upward, so that the top of the filter screen 3 contacts the bottom of the scraper 18, and controls the electric guide rail 17 to drive the scraper 18 to The filter element 12 is then moved to the right, and the particles on the filter screen 3 are scraped into the collecting frame 19, which is convenient for cleaning the particles on the filter screen 3 and collecting the cleaned particles. The first baffle 15 and the second baffle 16 can block the particles on the filter screen 3 to prevent the particles from falling from the filter screen 3. Then the valve 6 is opened, and the waste water in the box body 1 is discharged through the drain pipe 5. The filter element 12 can filter the tiny particles in the waste water to improve the treatment effect of the waste water. When it is necessary to switch the filter element 12, the staff pulls the rotating frame 11 forward, and the rotating frame 11 drives the filter element 12 to move forward, so that the filter element 12 and the drain pipe 5 are separated. The rotating frame 11 can also drive the mounting rod 10 to move forward, and the spring 9 continues to stretch, and then the rotating frame 11 is rotated. The rotating frame 11 drives the filter element 12 to rotate, so that the next filter element 12 corresponds to the front end of the drain pipe 5, and then the rotating frame 11 is pushed backward. The rotating frame 11 drives the filter element 12 to move backward, so that the drain pipe 5 is inserted into the filter element 12, and the switching of the filter element 12 is completed.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
