DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 5 In an embodiment of the utility model, a device for filtering wastewater after pharmaceutical processing includes a wastewater treatment pool 1 for treating pharmaceutical processing wastewater, a water inlet pipe 2 for introducing wastewater is installed on the top of the wastewater treatment pool 1, a filter assembly for separating solids in the wastewater is provided in the middle and upper part of the water inlet pipe 2, the filter assembly includes a filter plate 3 that can be flipped ninety degrees, a fixed shaft 4 is provided at one end of the filter plate 3, a backwash assembly for cleaning the filter plate 3 is installed on one side wall of the water inlet pipe 2, and a locking assembly for fixing the filter plate 3 is installed on the side wall of the water inlet pipe 2.

[0024] Wastewater generated by pharmaceutical processing enters the wastewater treatment tank 1 through the water inlet pipe 2. The filter plate 3 can filter the wastewater entering the wastewater treatment tank 1 and separate the solids in the wastewater. The filter plate 3 is installed in the middle and upper part of the water inlet pipe 2, and the fixed shaft 4 is installed at one end of the filter plate 3. The filter plate 3 can be rotated ninety degrees through the fixed shaft 4. When the filter plate 3 is laid flat in the water inlet pipe 2, the wastewater entering therein can be filtered. After the filter plate 3 is rotated ninety degrees, the filter plate 3 is in a vertical state. The filter plate 3 in the vertical state can be easily backwashed to avoid blockage caused by excessive solids accumulating on the surface of the filter plate 3 after a long time.

[0025] In one embodiment, specifically, the backwashing assembly includes a flushing pipe 7 installed inside the water inlet pipe 2, and a plurality of nozzles 8 are provided on the flushing pipe 7, and the nozzles 8 are arranged toward one side of the filter plate 3 placed in the vertical direction, and a movable frame 9 is installed on one side of the water inlet pipe 2, and a telescopic frame 10 is provided between the movable frame 9 and the water inlet pipe 2, and the flushing pipe 7 is installed on the movable frame 9, and the movable frame 9 is installed inside the water inlet pipe 2, and the telescopic frame 10 is installed between the side wall of the water inlet pipe 2 and the movable frame 9, and a plurality of flushing pipes 7 are laid flat on the movable frame 9 along the vertical plane, and the nozzles 8 are installed on one side of the flushing pipe 7. More specifically, the flushing pipe 7 is connected to an external water source through a conduit to facilitate backwashing of the filter plate 3.

[0026] Among them, the locking assembly includes a plug plate 12 installed on a side wall of the water inlet pipe 2, and a connecting rod 13 that can slide on the side wall of the water inlet pipe 2 is connected to one side of the plug plate 12. A movable groove 14 is provided on the side wall of the water inlet pipe 2, and a spring 15 is provided inside the movable groove 14. A pull ring 16 is connected to the outer side of the connecting rod 13. The plug plate 12 can move in and out of the side wall of the water inlet pipe 2. When the filter plate 3 is in a vertical state, the plug plate 12 can resist the bottom surface of the filter plate 3 to facilitate the fixation of the filter plate 3. The plug plate 12 is connected to the connecting rod 13. Pulling the pull ring 16 can drive the plug plate 12 to move in and out of the movable groove 14 through the connecting rod 13. The spring 15 on one side of the movable groove 14 can reset the plug plate 12, and can maintain the positioning of the plug plate 12 to the filter plate 3 without external interference.

[0027] On the basis of the above embodiment, specifically, a guide plate 5 is provided on one side of the top of the filter plate 3, and an edge 6 is provided around the top of the filter plate 3. The guide plate 5 and the edge 6 form a ring. A collecting tank 11 is installed on one side of the water inlet pipe 2. The collecting tank 11 is located below one end of the filter plate 3. The guide plate 5 is installed at one end of the filter plate 3 close to the fixed shaft 4. The edge 6 is connected to the guide plate 5 and forms a ring, which can accumulate a certain amount of wastewater on the filter plate 3 to prevent the wastewater from being discharged from the side of the guide plate 5 without being filtered. When the filter plate 3 is in a vertical state, the guide plate 5 abuts against the side wall of the collecting tank 11 at the bottom, and the solids on the filter plate 3 and the water used for backwashing will enter the collecting tank 11, which is convenient for cleaning the surface of the filter plate 3.

[0028] When filtering the wastewater generated by pharmaceutical processing, the filter plate 3 is placed in a horizontal state in the water inlet pipe 2 in advance, and then the wastewater is passed above the filter plate 3. When the wastewater enters the filter plate 3, the solids inside will be separated, and the filtered wastewater will enter the wastewater treatment tank 1 below for further treatment. After a certain period of use, a certain amount of solid impurities will accumulate on the surface of the filter plate 3, which will affect the normal filtration of the wastewater. At this time, stop adding wastewater, rotate the filter plate 3 ninety degrees, and keep the filter plate 3 in a vertical state. Then, the movable frame 9 is moved close to the filter plate 3, and blown to the bottom surface of the filter plate 3 through the flushing pipe 7 and the nozzle 8. Due to the setting of the guide plate 5, the solid impurities on the top surface of the filter plate 3 will be washed down and enter the collection tank 11 on one side through the guide plate 5, which is convenient for the long-term use of the filter plate 3.

[0029] In one embodiment, specifically, a top cover 17 is provided on the top of the water inlet pipe 2. The top cover 17 can prevent water from splashing out of the filter plate 3 during the backwashing process, making it easy to clean.
