[0030] Example 2

[0031] Please see Figure 5 The difference between this embodiment and Embodiment 1 is that:

[0032] The filter cake mechanism 10 includes a filter cake tank 101 located at the liquid outlet end of the sedimentation tank 9. A filter cake plate 102 is fixedly connected to the inner surface of the filter cake tank 101. A baffle plate 103 is slidably connected to one side surface of the filter cake tank 101. A baffle plate electric push rod 104 is fixedly connected to the top surface of the baffle plate 103. A slag outlet matching the structural dimensions of the baffle plate 103 is opened through one side surface of the filter cake tank 101. The outer surface of the sleeve end of the baffle plate electric push rod 104 is fixedly connected to the filter cake tank 101. The telescopic end of the baffle plate electric push rod 104 is fixedly connected to the baffle plate 103. The contraction of the baffle plate electric push rod 104 causes the baffle plate 103 to move upward, exposing the slag outlet, which is conducive to cleaning the sewage sedimentation residue on the top surface of the filter cake plate 102.

[0033] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the servo motor 72, the water pump 82, the left and right electric push rods 75 and the slag-blocking electric push rod 104, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, and will not further explain the electrical control.

[0034] The working principle and usage process of this utility model are as follows: When it is necessary to clean and replace the first filter plate 3 in the primary filter box 1, the limiting bolt 12 on the surface of the upper limit plate 11 of the second frame 4 is rotated off. Then, the first frame 2 and the first filter plate 3 are pushed into another cleaning box 6. The second frame 4 and the second filter plate 5 are located in the primary filter box 1. At this time, the sewage undergoes primary filtration through the second filter plate 5. Further, the water pump 82, the servo motor 72, and the left and right electric push rods 75 are started. The extension of the left and right electric push rods 75 drives the cleaning brush plate 76 to approach the first filter plate 3. The servo motor 72 drives the threaded rod 73 to rotate. During the process, the cleaning brush plate 76 assembly moves up and down, and the nylon brushes on the surface of the cleaning brush plate 76 brush and clean the first filter plate 3. Further, the water pump 82 pumps water from the water storage tank 81 into the three-way pipe 83, which enters the two spray pipes 77 and is sprayed out through the spray head to rinse the first filter plate 3, thus conveniently completing the cleaning of the first filter plate 3. Further, when it is necessary to clean the sewage sediment residue above the filter cake plate 102, the electric push rod 104 for blocking the residue is retracted, thereby driving the blocking plate 103 to move upward and expose the slag outlet, which is conducive to cleaning the sewage sediment residue on the top surface of the filter cake plate 102.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
