The disassembly and installation steps of the screen are relatively cumbersome and inconvenient to use. In addition, after long-term use, a large amount of impurities will adhere to the inside of the return pipe of the existing circulating gasoline detection and screening device, causing the diameter of the return pipe to become smaller, affecting the reflux efficiency of gasoline. For this reason, we propose a circulating gasoline detection and screening device. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. For the circulating gasoline detection and screening device, when the screen needs to be replaced, the connecting rod is pulled so that the connecting rod drives the pressure plate to squeeze the reset spring and then rise, so that the tenons on both sides of the bottom of the pressure plate leave the interior of the screen and reset to the mounting plate, the fixation of the screen is canceled and the screen is then pulled out of the filter bin. When installing the screen afterwards, the screen is inserted into the filter bin, and then the connecting rod is loosened to reset the reset spring squeezed by the pressure plate, and the pressure plate is pushed down to insert the tenon into the interior of the screen to fix the screen, so that the screen can be disassembled and installed quickly and conveniently, saving time and effort and being easy to use.

The bottom ends of the tenons 131 on the front and rear sides penetrate the mounting plate 120 and the screen 110 and extend to the bottom of the screen 110. The top of the mounting plate 120 is plugged with a connecting rod 140. The connecting rod 140 is used to connect the pressing plate 130. The bottom end of the connecting rod 140 passes through the mounting plate 120 and extends to the inner cavity of the mounting plate 120, and the bottom end of the connecting rod 140 is fixedly connected to the pressing plate 130. The outer wall of the connecting rod 140 is sleeved with a return spring 141, and the return spring 141 is used to push the pressing plate 130 down. When the screen 110 needs to be replaced, the connecting rod 140 is pulled so that the connecting rod 140 drives the pressing plate 130 to squeeze the return spring 141 and then rise, so that the bottom of the pressing plate 130 The tenons 131 on both sides leave the interior of the screen 110 and return to the mounting plate 120, cancel the fixation of the screen 110, and then pull the screen 110 out of the filter bin 100. When installing the screen 110, the screen 110 is inserted into the filter bin 100, and then the connecting rod 140 is loosened to reset the reset spring 141 squeezed by the pressing plate 130, and the pressing plate 130 is pushed down to make the tenons 131 insert into the interior of the screen 110 to fix the screen 110.

[0029] In summary, the screen 110 can be disassembled and installed quickly and conveniently, saving time and effort and being easy to use;

[0030] Please refer again Figure 1-4 The first delivery pipe 200 is fixedly connected to the lower side of the left side wall of the filter bin 100, and the left end of the first delivery pipe 200 is fixedly connected to a reflux pipe 210, and the reflux pipe 210 is used to reflux gasoline. The top of the reflux pipe 210 is fixedly connected to a second delivery pipe 220, and the second delivery pipe 220 is used to deliver gasoline. The outer wall of the second delivery pipe 220 is fixedly connected to a reflux pump 221, and the reflux pump 221 is used to pump gasoline reflux. The bottom end of the reflux pipe 210 is fixedly connected to a mounting pipe 230, and the mounting pipe 230 is used to install a motor 240. The bottom end of the inner cavity of the mounting pipe 230 is fixedly connected to a motor 240, and the motor 240 is used to drive the threaded rod 241 to rotate. The top of the power output shaft of the motor 240 is fixedly connected to a threaded rod 241, and the threaded rod 241 is used to install a cleaning brush plate 242. The top of the threaded rod 241 passes through the mounting pipe 230 and extends to the inner cavity of the reflux pipe 210. The top of the threaded rod 241 is rotatably connected to the return pipe 210, and a cleaning brush plate 242 is screwed on the lower side of the outer wall of the threaded rod 241. The cleaning brush plate 242 is used to clean impurities on the inner wall of the return pipe 210. The left side of the outer wall of the cleaning brush plate 242 is slidably connected to the return pipe 210. When the inner wall of the return pipe 210 needs to be cleaned, the threaded rod 241 is driven to rotate by starting the motor 240, so that the cleaning brush plate 242 installed on the threaded rod 241 follows the rotation of the threaded rod 241 to rise. Since the cleaning brush plate 242 is slidably connected to the return pipe 210, the cleaning brush plate 242 will not rotate with the threaded rod 241, and can only move vertically to clean the impurities attached to the inner wall of the return pipe 210. Subsequently, the impurities are transported to the screen 110 of the filter bin 100 by the second delivery pipe 220 along with the gasoline pumped by the reflux pump 221.

[0031] In summary, the impurities attached to the inner wall of the reflux pipe 210 can be automatically cleaned to prevent the impurities from affecting the reflux efficiency of gasoline;

[0032] During specific use, the technical personnel in this field pour gasoline into the feed port. The gasoline is filtered through the multiple layers of screens 110 due to gravity. Then the reflux pump 221 is started to pump the gasoline at the bottom of the inner cavity of the filter bin 100 through the first delivery pipe 200 to the reflux pipe 210, and then the gasoline is transported to the uppermost screen 110 through the second delivery pipe 220 for re-filtration. After the gasoline reaches the use standard, the discharge hole is opened to discharge the gasoline. When the screen 110 needs to be replaced, the connecting rod 140 is pulled so that the connecting rod 140 drives the pressure plate 130 to squeeze the return spring 141 and then rise, so that the tenons 131 on both sides of the bottom of the pressure plate 130 leave the inside of the screen 110 and return to the mounting plate 120, the fixation of the screen 110 is canceled, and the screen 110 is then pulled out of the filter bin 100. Later, when the screen 110 is installed, By inserting the screen 110 into the filter bin 100 and then loosening the connecting rod 140 to reset the return spring 141 squeezed by the pressure plate 130, the pressure plate 130 is pushed down to allow the tenon 131 to be inserted into the screen 110 to fix the screen 110. When the inner wall of the return pipe 210 needs to be cleaned, the threaded rod 241 is driven to rotate by starting the motor 240, so that the cleaning brush plate 242 installed on the threaded rod 241 rises along with the rotation of the threaded rod 241. Since the cleaning brush plate 242 is slidably connected to the return pipe 210, the cleaning brush plate 242 will not rotate along with the threaded rod 241, and can only move vertically to clean the impurities attached to the inner wall of the return pipe 210. Subsequently, the impurities are transported to the screen 110 of the filter bin 100 by the second delivery pipe 220 along with the gasoline subsequently pumped by the reflux pump 221.
