[0026] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0027] Embodiment 1, a pre-treatment device for detecting sewage, comprises a treatment box 1 and a filter box 2, characterized in that:

[0028] The processing box 1 is slidably connected with a filter box 2, a sealing ring is provided between the filter box 2 and the processing box 1, a water inlet pipe 3 is provided on the top of the processing box 1, and a water outlet pipe 4 is provided on the bottom, and the filter box 2 is driven by a power device;

[0029] The filter box 2 is provided with a first filter plate 5, a second filter plate 6 and a third filter plate 7 at intervals, and the first filter plate 5, the second filter plate 6 and the third filter plate 7 are detachably connected to an impurity collection box 8 at the bottom, and a water filter hole 9 is provided at the bottom of the impurity collection box 8;

[0030] The first filter plate 5, the second filter plate 6 and the third filter plate 7 are all slidably connected with a movable plate 10, and a cleaning brush 11 is provided at the bottom of the movable plate 10;

[0031] The first filter plate 5, the second filter plate 6 and the third filter plate 7 are all provided with magnets 12, and the movable plate 10 is provided with a magnetic attraction plate 13 cooperating with the magnets 12;

[0032] The power device includes two sets of electric telescopic rods 14 provided on the processing box 1, the output ends of the two sets of electric telescopic rods 14 are connected to the filter box 2, and the two sets of electric telescopic rods 14 are electrically connected to the controller;

[0033] The filtration hole diameter of the first filter plate 5 is not less than the filtration hole diameter of the second filter plate 6, the filtration hole diameter of the second filter plate 6 is not less than the filtration hole diameter of the third filter plate 7, and the filtration hole diameters of the first filter plate 5, the second filter plate 6 and the third filter plate 7 are not less than the filtration hole diameter 9;

[0034] The first filter plate 5, the second filter plate 6 and the third filter plate 7 are tilted toward the impurity collecting box 8, and the tilt angle with the horizontal plane is 30 degrees;

[0035] The electric telescopic rod 14 is a servo electric cylinder 13EC65T with a guide rod.

[0036] When in use, sewage enters the treatment box 1 from the water inlet pipe 3, passes through the first filter plate 5, the second filter plate 6 and the third filter plate 7. Since the filter hole diameter of the first filter plate 5 is not less than the filter hole diameter of the second filter plate 6, and the filter hole diameter of the second filter plate 6 is not less than the filter hole diameter of the third filter plate 7, the purpose of multi-stage filtration can be achieved, and the performance of filtering impurities is further improved.

[0037] Since the first filter plate 5, the second filter plate 6 and the third filter plate 7 are inclined toward the impurity collection box 8, and the inclination angle with the horizontal plane is set at 30 degrees, when the impurities fall on the first filter plate 5, the second filter plate 6 and the third filter plate 7, they roll along the inclined surfaces of the first filter plate 5, the second filter plate 6 and the third filter plate 7 and fall into the impurity collection box 8;

[0038] After long-term use, impurities may remain on the inclined surfaces of the first filter plate 5, the second filter plate 6 and the third filter plate 7, which may cause the risk of clogging the first filter plate 5, the second filter plate 6 and the third filter plate 7. At this time, stop the sewage from entering, drive the electric telescopic rod 14, move the filter box 2 out of the treatment box 1, drive the moving plate 10, so that each group of moving plates 10 can slide along the inclined surfaces of the first filter plate 5, the second filter plate 6 and the third filter plate 7, and clean the remaining impurities into the impurity collection box 8 under the action of the cleaning brush 11, waiting for centralized treatment;

[0039] After the cleaning is completed, the movable plate 10 is reset, and under the action of the magnet 12 and the magnetic attraction plate 13, the movable plate 10 is attracted to the magnet 12 to ensure that the movable plate 10 does not slide under normal conditions, thereby playing a locking role;

[0040] When cleaning the impurity collection box 8, the electric telescopic rod 14 is driven to move the filter box 2 out of the processing box 1. Each group of impurity collection boxes 8 is slidably connected with the inner side walls of the first filter plate 5, the second filter plate 6 and the third filter plate 7. Dovetail grooves are provided on the first filter plate 5, the second filter plate 6 and the third filter plate 7, and dovetail blocks are provided on each group of impurity collection boxes 8.

[0041] The above-mentioned connection makes it easy to take out the impurity collection box 8 for cleaning. After cleaning, the impurity collection box 8 is reset, and the filter box 2 is also reset. Under the action of the inner wall of the processing box 1, the impurity collection box 8 will not shake.

[0042] The filter box 2 is provided with a sealing ring that matches the inner wall of the treatment box 1, so that no leakage occurs.

[0043] Embodiment 2, on the basis of embodiment 1, the inner wall of the processing box 1 is provided with a large impurity filter plate 15 located on the upper side of the filter box 2, the processing box 1 is provided with a baffle 16 corresponding to the large impurity filter plate 15, a sealing ring is provided between the baffle 16 and the processing box 1, and the baffle 16 and the processing box 1 are detachably connected;

[0044] The processing box 1 is provided with a large cleaning port 17, and a baffle 16 is slidably connected to the large cleaning port 17. A positioning column 18 is slidably connected to the processing box 1, and a positioning handle 19 is provided at one end of the positioning column 18. The baffle 16 is provided with a positioning hole 20 that matches the positioning column 18, and a return spring 21 is provided between the positioning handle 19 and the processing box 1;

[0045] The filter hole diameter of the large impurity filter plate 15 is not less than the filter hole diameters of the first filter plate 5, the second filter plate 6 and the third filter plate 7;

[0046] The large impurity filter plate 15 is tiltedly arranged on the inner wall of the treatment box 1, and its tilt angle with the horizontal plane is 30 degrees.

[0047] When in use, the sewage first passes through the large impurities filter plate 15, and the large impurities filter plate 15 filters the large impurities, including large particles, large mud blocks, etc., and the above impurities are filtered out, thereby reducing the risk of blockage in subsequent filtration;

[0048] After long-term use, when it is necessary to clean up large debris, the positioning handle 19 is used to separate the positioning column 18 from the positioning hole 20, and the baffle is moved at this time, so that the large debris cleaning port 17 is no longer sealed, and the large debris in the large debris cleaning port 17 is cleaned up, and the baffle 16 is reset. Under the action of the reset spring 21, the positioning hole 20 cooperates with the positioning column 18 to lock the baffle 16 to complete the cleaning task;

[0049] Since a sealing ring is provided between the baffle plate 16 and the large debris cleaning port 17, leakage will not occur.

[0050] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
