The filter element is easy to replace, the filter plate can be replaced according to the use environment, and the filter element can be folded for easy storage and carrying.

[0017] 1. When the present invention is in use, the support plate can support the filter element assembly. When filtering sewage, the sewage flows into the temporary storage chamber from the water inlet, and then enters the filter element assembly through the water outlet. The filtered sewage leaves the frame from the water outlet for subsequent purification. As the impurities adsorbed by the filter element assembly increase, the overall weight of the filter element assembly increases, and the support plate can be lowered to compress the support spring. When the filter element assembly reaches the absorption limit, the support plate contacts the pressure sensor, and the pressure sensor can control the electric shaft to drive the flip frame to rotate in the frame to switch the filter element assembly, thereby flipping the spare filter element to the top of the frame to continue filtering sewage, thereby preventing the staff from forgetting to replace the filter element and causing the device to fail to operate normally. During the switching, the flip frame can close the water outlet to prevent sewage leakage. The sewage can be temporarily stored in the temporary storage chamber to prevent the continuous input of sewage from causing excessive pressure in the frame, and the check valve can prevent sewage from flowing back. In summary, when in use, after the filter element reaches the absorption limit, it can automatically switch to the spare filter element to work, thereby preventing the staff from forgetting to replace the filter element and causing the device to fail to operate normally.

[0018] The electromagnetic sheet is energized to place the expanded filter element assembly on the support plate, allowing the base to be snapped into the mounting slot and the connecting rod to be snapped into the connecting slot. The electromagnetic sheet is de-energized, and the fixing spring can drive the fixing plate to rebound, restricting the connecting rod, thereby fixing the base in the mounting slot, completing the replacement of the filter element assembly. The plug-in board is then inserted into the flip frame through the plug-in slot until the plug-in board is close to the frame, and the clamping rod is rotated to a vertical state to fix the plug-in board. In summary, the filter element assembly can be conveniently replaced during use.

[0019] 3. When the filter element assembly is carried, the filter element assembly can be folded by the connecting rod and the bellows while maintaining the connection between the bases, thereby reducing the space occupied by the filter element assembly and facilitating its storage. When in use, the two outermost bases are pulled to stretch the bellows, and the connecting rod rotates as the bases move away from each other to maintain the connection between the bases. After fully expanded, it can be installed. When installing the filter element assembly, the connecting port and the drain port are respectively installed corresponding to the water port and the water outlet, so that when filtering sewage, the sewage can enter the cavity formed between the base and the bellows from the water port through the connecting port, and the filter After the plate filters the sewage, the sewage can leave the frame from the drain port through the water outlet. Before use, the filter plate can be replaced according to the situation of the sewage, so as to filter the sewage in a targeted manner. When replacing the filter plate, you only need to pull the plug rod out of the slot and the socket, and then pull the filter plate out of the base through the sealing plate, and then insert the filter plate to be replaced into the placement slot, and insert the plug rod from the socket into the slot to restrict the filter plate through the sealing plate and fix it in the base. In summary, when in use, the filter element assembly can be folded and stored for easy carrying, and the filter plate can be replaced according to the different sewage during use, so as to filter the sewage in a targeted manner.

When installing the filter element assembly 9, the communication port 907 and the drain port 908 are respectively installed corresponding to the water passing port 209 and the water outlet 6, and then the plug-in board 205 is inserted into the flipping frame 202 through the plug-in slot 204 until the plug-in board 205 is close to the frame 1, and then rotate the clamping rod 7 to the vertical state to fix the plug-in board 205. When carrying the filter element assembly 9, the filter element assembly 9 can be folded by the connecting rod 903 and the corrugated pipe 902 while maintaining the connection between the bases 901, so as to reduce the occupied space of the filter element assembly 9 and facilitate its storage. During use, pull the two outermost bases 901 to stretch the corrugated pipe 902, and the connecting rod 903 rotates as the bases 901 move away from each other, maintaining the connection between the bases 901. After complete expansion, it can be installed. Before use, the filter plate 909 can be replaced according to the situation of the sewage, so as to filter the sewage targeted.
