It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0024] The specific configuration and function of this embodiment are described in detail below. When the solid particles are stuck in the holes of the No. 1 filter 32 and the No. 2 filter 33, the electric telescopic rod 35 drives the mounting frame 4 to perform linear reciprocating motion. Since the mounting frame 4 is arranged between the No. 1 filter 32 and the No. 2 filter 33, and a number of No. 1 impurity removal rods 41 and No. 2 impurity removal rods 42 are fixedly installed on both sides of the mounting frame 4, a number of No. 1 impurity removal rods 41 are facing the holes of the No. 1 filter 32, and a number of No. 2 impurity removal rods 42 are fixedly installed on both sides of the mounting frame 4. The impurity removal rod 42 is directly opposite to the holes of the No. 2 filter screen 33. When the mounting frame 4 makes linear reciprocating motion, the No. 1 impurity removal rod 41 and the No. 2 impurity removal rod 42 push the solid particles out of the holes of the No. 1 filter screen 32 and the No. 2 filter screen 33, avoiding the situation where workers need to be arranged to clean the No. 1 filter screen 32 and the No. 2 filter screen 33 regularly due to solid particles being stuck in the holes of the No. 1 filter screen 32 and the No. 2 filter screen 33, thereby reducing the manpower cost of the factory to repair the electrodialysis wastewater treatment device. Example

[0025] like Figure 2 and Figure 3As shown, the input end of the electrodialysis unit 1 is fixedly connected to a drainage pipe assembly 2, and the input end of the drainage pipe assembly 2 is fixedly connected to a plurality of sewage treatment boxes 3. The plurality of sewage treatment boxes 3 include a box body 31, and a plurality of impurity collecting bins 36 are fixedly installed on one side of the box body 31. An impurity cleaning port 361 is provided on one side of the impurity collecting bin 36. A water-blocking baffle 362 is movably connected inside the impurity cleaning port 361. A shift block 363 is fixedly installed on one side of the top surface of the water-blocking baffle 362. A movable circular groove 321 is symmetrically provided on one side of the No. 1 filter screen 32, and a driving rod of the electric telescopic rod 35 is movably connected inside the movable circular groove 321.

[0026] The effect achieved by the entire embodiment is that since the No. 1 filter 32 and the No. 2 filter 33 are installed obliquely inside the box body 31, the filtered solid particles are rolled into the impurity collection bin 36 under the action of gravity. When a certain volume of solid particles accumulates inside the impurity collection bin 36, the worker grasps the shift block 363 to drive the water-blocking baffle 362 to slide, thereby removing the blocking of the impurity cleaning port 361 by the water-blocking baffle 362, thereby facilitating the worker to clean out the solid particles inside the impurity collection bin 36, so that the worker can clean the solid particles inside the box body 31 without removing the box cover 34, thereby improving the efficiency of cleaning the electrodialysis wastewater treatment device.

[0027] The usage and working principle of this device are as follows: the sewage first enters the interior of the secondary water inlet pipe 343, at which time only a single valve 342 is in an open state, and the sewage enters the primary water inlet pipe 341 through the open valve 342, and then enters the interior of the box body 31 through the primary water inlet pipe 341, and the solid particles in the sewage are filtered out by the No. 1 filter 32 and the No. 2 filter 33, completing the pretreatment of the sewage, preventing the solid particles in the sewage from entering the interior of the electrodialyzer 1 and causing mechanical damage to the electrodialyzer 1, thereby extending the service life of the electrodialysis sewage treatment device, when the solid particles are stuck in the holes of the No. 1 filter 32 and the No. 2 filter 33, the electric telescopic rod 35 drives the mounting frame 4 to perform linear reciprocating motion, because the mounting frame 4 is arranged between the No. 1 filter 32 and the No. 2 filter 33, and both sides of the mounting frame 4 Several No. 1 impurity removing rods 41 and No. 2 impurity removing rods 42 are fixedly installed respectively, several No. 1 impurity removing rods 41 are opposite to the holes of No. 1 filter screen 32, and several No. 2 impurity removing rods 42 are opposite to the holes of No. 2 filter screen 33. When the mounting frame 4 makes linear reciprocating motion, the No. 1 impurity removing rods 41 and No. 2 impurity removing rods 42 push the solid particles out of the holes of No. 1 filter screen 32 and No. 2 filter screen 33; since the No. 1 filter screen 32 and No. 2 filter screen 33 are tilted, the filtered solid particles are rolled into the interior of the impurity collecting bin 36 by the action of gravity. When a certain volume of solid particles accumulates in the interior of the impurity collecting bin 36, the worker grasps the shifting block 363 to drive the water-proof baffle 362 to slide, thereby removing the blocking of the impurity cleaning port 361 by the water-proof baffle 362, thereby facilitating the worker to clean out the solid particles in the impurity collecting bin 36.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
