The circulation pump 5 is a prior art and is connected to the filtrate box 4 through the suction end of the circulation pump 5, so that the sulfadiazine entering the filtrate box 4 can be fully filtered and then pumped into the reaction tank 2 through the circulation pipe 6.

The outer wall of the circulation pump 5 is detachably mounted on the circulation pipe 6 through a flange.

[0033] Reference Figure 2 and Figure 4 The inner wall of the right side of the circulating pump 5 is provided with a filter assembly 10, and the filter assembly 10 includes a rotating ring 101, which passes through and is rotatably connected to the inner side wall of the circulating pump 5. A semi-annular notch is provided at the top of the circulating pump 5, so that the rotating ring 101 as a whole can rotate on the inner wall of the circulating pump 5, and the connecting block 103 is rotatably connected to the inner side wall of the connecting pipe of the circulating pump 5. The inner side wall of the connecting pipe of the circulating pump 5 is provided with an annular groove that fits the connecting block 103, so that the connecting block 103 as a whole can rotate on the inner wall of the annular groove of the circulating pump 5. The inner side wall of the rotating ring 101 is fixedly connected to a T-shaped rod 102, and the center point of the outer wall of the T-shaped rod 102 is fixedly connected to the connecting block 103. The T-shaped rod 102 is provided on the inner wall of the rotating ring 101 to support the connecting block 103, so that the rotating ring 101 can rotate half a circle, so that the connecting block 103 can fully contact the surface of the filter screen 11.

[0034] Reference Figure 4The inner wall of the connecting block 103 is elastically connected to the dredging ball 105 through a return spring 104. One end of the return spring 104 is fixedly connected to the bottom end of the outer wall of the dredging ball 105, and the other end of the return spring 104 is fixedly connected to the inner wall of the connecting block 103. The function of the return spring 104 is to automatically reset the position of the front end of the dredging ball 105 after being squeezed and moved. The dredging ball 105 is slidably connected to the inner wall of the connecting block 103. The right inner wall of the circulating pump 5 is fixedly connected to the filter screen 11. By providing the filter screen 11, Thereby, the sulfadiazine pumped into the circulation pump 5 can be blocked to prevent large particles of material from being sucked into the interior of the circulation pump 5, which may cause wear of the internal impeller. The surface of the filter screen 11 is provided with multiple groups of filter holes, and the outer wall of the dredging ball 105 is in contact with the inner wall of the filter hole. The contact between the two can dredge the sulfadiazine that may be blocked in the filter hole of the filter screen 11, thereby avoiding clogging of the filter screen 11. The circulation pump 5 as a whole cannot pump the sulfadiazine after filtering into the filtrate box 4.

[0035] Reference Figure 2 and Figure 3 The inner wall of the flange connection of the filtrate box 4 is elastically connected with an insert block 9 by a limit spring 8. One end of the limit spring 8 is fixedly connected to the inner wall of the connecting flange of the filtrate box 4, and the other end of the limit spring 8 is fixedly connected to the surface of the insert block 9. The function of the limit spring 8 is to automatically reset the position of the insert block 9 after being squeezed and moved. The insert block 9 passes through and is slidably connected to the inner wall of the connecting flange of the filtrate box 4. The surface of the flange connection of the filtrate box 4 is fixedly connected with a positioning block 7. A through hole is provided on the surface of the connecting flange of the circulating pump 5. The insert block 9 is plugged into the inner wall of the through hole. The plugging between the two can make it possible for the positioning block 7 to enter the inner wall of the positioning groove corresponding to the connecting flange of the circulating pump 5 and rotate into place when the inner wall of the positioning groove is rotated into place. The insert block 9 will be plugged into the through hole on the surface of the flange of the circulating pump 5, thereby aligning the hole positions of the flanges of the filtrate box 4 and the circulating pump 5 for preliminary fixation, thereby facilitating the staff to rotate the bolts to install it. The surface of the circulating pump 5 is provided with a positioning groove, and the outer wall of the positioning block 7 contacts the inner wall of the positioning groove.

[0036] Working principle: When sulfadiazine is sucked into the circulation pump 5, it is first filtered through the filter screen 11. The filter screen 11 blocks large particles to prevent them from entering the circulation pump 5 and causing wear of the impeller. During the filtering process, if the filter holes of the filter screen 11 are blocked by sulfadiazine, the rotating ring 101 is rotated. Since the rotating ring 101 can rotate on the inner wall of the circulation pump 5 and is connected to the connecting block 103 through the T-shaped rod 102, when the rotating ring 101 rotates half a circle, the connecting block 103 can contact the surface of the filter screen 11, and the dredging ball 105 in the connecting block 103 is released by the reset spring 10. 4, it contacts the inner wall of the filter pores of the filter screen 11. When the connecting block 103 contacts the filter screen 11, the front end of the dredging ball 105 is squeezed and moves toward the inside of the connecting block 103 and compresses the reset spring 104. As the connecting block 103 moves, the dredging ball 105 dredges the sulfadiazine that may be blocked in the filter pores of the filter screen 11, avoiding the blockage of the filter screen 11 and causing the circulation pump 5 to be unable to pump the sulfadiazine filtered into the filtrate box 4. After the dredging is completed, the reset spring 104 automatically resets the position of the dredging ball 105 after being squeezed and moved.

[0037] When installing the filtrate box 4 and the circulation pump 5, align the connecting flange of the filtrate box 4 with the connecting flange of the circulation pump 5, insert the positioning block 7 on the connecting flange of the filtrate box 4 into the positioning groove on the surface of the connecting flange of the circulation pump 5, and rotate the positioning block 7 to rotate on the inner wall of the positioning groove. When the positioning block 7 is rotated into place on the inner wall of the positioning groove, the insert block 9 is plugged into the through hole on the surface of the flange of the circulation pump 5 under the action of the limit spring 8. At this time, the position where the hole positions of the flanges of the filtrate box 4 and the circulation pump 5 are aligned is preliminarily fixed, which is convenient for the staff to rotate the bolts to install it. The limit spring 8 automatically resets the position of the insert block 9 after it is squeezed and moved, thereby avoiding the troublesome and inconvenient installation of the internal thread which will produce water rust at the thread.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
