[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses an impurity filtering device for rural water supply and drinking water.

[0026] The utility model provides Figure 1-3 The impurity filtering device for rural water supply and drinking water shown in the figure comprises a jacket 1, the longitudinal section of the jacket 1 is U-shaped, both sides of the jacket 1 are threadedly penetrated with clamping bolts 2, a support plate 3 is fixedly provided on the top of the jacket 1, a cross bar 4 is rotatably penetrated inside the support plate 3, two symmetrically arranged connecting rods 5 are fixedly provided on the rod wall of the cross bar 4, a guide tube 6 is fixedly provided on the end of the connecting rod 5, a sealing assembly is provided at one end of the guide tube 6, and two clamps 8 connected by locking bolts 7 are sleeved on the other end of the guide tube 6, and a filter mesh bag 9 is fixedly provided on the side walls of the two clamps 8.

[0027] In rural water supply, before the device is used, the jacket 1 is installed on the outside of the water outlet pipe of the water pump, and the position of the jacket 1 is determined by the clamping bolt 2, and then the guide pipe 6 is connected with the water outlet pipe of the water pump. At this time, during the water supply process, underground well water enters the filter mesh bag 9 through the guide pipe 6, and the impurities inside the water are quickly filtered through the filter mesh bag 9. When there are more impurities inside the lower filter mesh bag 9, the two filter mesh bags 9 can be switched by rotating the cross bar 4 to ensure that the filtering work of the water can be carried out continuously. At the same time, with the cooperation of the clamp 8 and the locking bolt 7, the filter mesh bag 9 can be separated from the guide pipe 6, which is convenient for cleaning the impurities inside the filter mesh bag 9 and replacing the fire pile filter mesh bag 9 as a whole to ensure the filtering effect.

[0028] In order to be able to quickly switch and position the two filter bags 9, Figure 1-2As shown, a switching positioning mechanism for limiting the rotational position of the cross bar 4 is provided between the cross bar 4 and the support plate 3, and the switching positioning mechanism includes a card plate 10, a pulling hole is provided at the inner upper end of the card plate 10, two symmetrically arranged mounting plates 11 are fixedly provided at the upper end of the outer wall of the support plate 3, a mounting rod 12 is fixedly provided between the two mounting plates 11, the card plate 10 is located between the two mounting plates 11, and is rotatably sleeved with the mounting rod 12, the rod wall of the cross bar 4 is provided with two symmetrically arranged slots, the lower end of the card plate 10 is inserted into the slots, and the rod wall of the mounting rod 12 is sleeved with two torsion springs 13, and the two ends of the torsion spring 13 are respectively fixedly connected to the mounting plate 11 and the card plate 10.

[0029] Before switching the two filter mesh bags 9, the card plate 10 is pulled through the pulling hole. At this time, the card plate 10 rotates around the mounting rod 12 and twists the torsion spring 13. At this time, the card plate 10 is pulled out of the card slot, and then the cross bar 4 can be rotated so that the two filter mesh bags 9 can be switched. After the switching work is completed, the card plate 10 can be loosened. Under the torsion recovery of the torsion spring 13, the card plate 10 can rotate and continue to be inserted into the card slot to fix the position of the cross bar 4 and the filter mesh bag 9 to ensure continuous and stable water filtration.

[0030] In order to ensure that the water can stably enter the flow guide tube 6 and complete the filtration during the water impurity filtration process, Figure 1 As shown, the sealing assembly includes a sealing ring 14, which is a rubber sealing ring. The sealing ring 14 is slidably sleeved with the outer wall of the guide tube 6. Slide rods 15 are fixedly provided at both ends of the side of the sealing ring 14. The outer wall of the guide tube 6 is provided with two symmetrically arranged slide grooves. The slide rod 15 is slidably arranged in the slide groove, and a spring 16 is fixedly provided between the slide rod 15 and the inner wall of the slide groove.

[0031] Before and after the filter mesh bag 9 switches its position, the sealing ring 14 can be pulled horizontally. Under the sliding cooperation of the slide rod 15 and the slide groove, the sealing ring 14 moves along the wall of the guide tube 6 and squeezes the spring 16. When the guide tube 6 and the water outlet pipe of the water pump are in the same straight line, the sealing ring 14 is released. The elastic force of the spring 16 can restore the sealing ring 14 and enable it to rebound and be sleeved on the outside of the water outlet pipe of the water pump, thereby ensuring the sealing ring during the connection process of the guide tube 6, so that the water can stably enter the guide tube 6 and complete the filtration of impurities, thereby improving the filtration effect.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
