DETAILED DESCRIPTION

[0023] 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.

[0024] The utility model embodiment discloses a seawater desalination pre-treatment filter. Figure 1-4 A desalination pretreatment filter comprises a filter tube 1, a mounting frame 4, a cleaning mechanism 6 and a knocking mechanism 7. An inlet pipe 2 and an outlet pipe 3 are respectively arranged on the outside of the filter tube 1, and the inlet pipe 2 and the outlet pipe 3 are both connected to the filter tube 1. The mounting frame 4 is arranged inside the filter tube 1. A first filter screen 5 is arranged inside the mounting frame 4 for filtering the seawater. The cleaning mechanism 6 is arranged inside the filter tube 1 and away from the first filter screen 5, and is used to automatically clean the first filter screen 5.

[0025] Reference Figure 4 The knocking mechanism 7 is arranged on one side of the mounting frame 4 , and is used for cooperating with the cleaning mechanism 6 to clean the first filter screen 5 .

[0026] Reference Figure 2 The cleaning mechanism 6 includes a rotating rod 601, a cleaning brush 602 and four connecting plates 603. The rotating rod 601 is rotatably arranged on one side of the inner part of the filter tube 1. The cleaning brush 602 is arranged at one end of the rotating rod 601 away from the inner wall of the filter tube 1, and the end of the cleaning brush 602 away from the rotating rod 601 is in contact with the first filter screen 5. The four connecting plates 603 are distributed on the outer side of the rotating rod 601 in a cylindrical array.

[0027] By adopting the above technical solution, when seawater falls from the water inlet pipe 2 into the filter tube 1, the seawater will impact the connecting plate 603. The impact on the connecting plate 603 will drive the rotating rod 601 to rotate. The rotation of the rotating rod 601 can drive the cleaning brush 602 to rotate, and the cleaning brush 602 can be used to automatically clean the first filter screen 5.

[0028] Reference Figure 4 The knocking mechanism 7 is provided with four groups, and the knocking mechanism 7 includes a connecting shaft 701, a knocking block 702 and a spring 703. The connecting shaft 701 is arranged on one side of the installation frame 4, the knocking block 702 is rotatably arranged at one end of the connecting shaft 701 away from the installation frame 4, and one end of the knocking block 702 is in contact with the inner wall of the installation frame 4, and the spring 703 is arranged at one end of the knocking block 702, and the end of the spring 703 away from the knocking block 702 is connected to the inner wall of the installation frame 4.

[0029] By adopting the above technical solution, the cleaning brush 602 will contact the knocking block 702 and squeeze the knocking block 702 during the rotation. The knocking block 702 will squeeze the spring 703. When the cleaning brush 602 is separated from the knocking block 702, the squeezing force on the knocking block 702 disappears. At this time, the elastic force of the spring 703 can drive the knocking block 702 to reset and touch the inner wall of the installation frame 4, so that the installation frame 4 can be knocked. The cleaning effect of the first filter screen 5 is further improved in cooperation with the cleaning brush 602.

[0030] Reference Figure 1 and Figure 3 A drain port 8 is provided at the bottom of the mounting frame 4 to facilitate the discharge of impurities on the first filter screen 5; a discharge pipe 9 is connected to the bottom of the filter tube 1, and the discharge pipe 9 is located below the drain port 8, and a valve 10 is provided on the outside of the discharge pipe 9.

[0031] By adopting the above technical solution, the impurities cleaned out from the first filter screen 5 can fall into the interior of the discharge pipe 9 through the sewage outlet 8, and the impurities can be discharged by opening the valve 10.

[0032] Reference Figure 1 A second filter screen 11 is provided at the inner upper end of the water inlet pipe 2 , and the filter diameter of the second filter screen 11 is larger than the filter diameter of the first filter screen 5 , so as to prevent larger impurities from entering the interior of the filter tube 1 .

[0033] By adopting the above technical solution, when seawater enters the interior of the filter tube 1 , the second filter screen 11 can filter out larger impurities in the seawater, thereby preventing the larger impurities from entering the interior of the filter tube 1 .

[0034] Working principle: When the utility model is used, the seawater is introduced into the water inlet pipe 2 for filtering treatment before desalination. The larger impurities in the seawater are first filtered by the second filter screen 11. Then, after the seawater enters the interior of the filter tube 1 through the water inlet pipe 2, the first filter screen 5 can be used to further filter the seawater. The filtered seawater is discharged through the water outlet pipe 3. In the process of the seawater falling from the water inlet pipe 2 into the filter tube 1, the connecting plate 603 is impacted. The impact on the connecting plate 603 drives the rotating rod 601 to rotate. The rotation of the rotating rod 601 can drive the cleaning brush 602 to rotate. Then, the cleaning brush 602 can be used to filter the first filter. The net 5 is automatically cleaned to prevent the first filter net 5 from being blocked and affecting its use. During the rotation of the cleaning brush 602, it will contact the knocking block 702 and squeeze the knocking block 702. The knocking block 702 will be squeezed and the spring 703 will be squeezed. After the cleaning brush 602 is separated from the knocking block 702, the squeezing force on the knocking block 702 disappears. At this time, the elastic force of the spring 703 can drive the knocking block 702 to reset and touch the inner wall of the installation frame 4, so that the installation frame 4 can be knocked. Then, in cooperation with the cleaning brush 602, the cleaning effect of the first filter net 5 is further improved, and there is no need to use electrical equipment, which greatly saves the cost of using the filter.

[0035] When the utility model is in use, the first filter screen 5 can be automatically cleaned while filtering the seawater, which not only ensures the cleaning effect of the first filter screen 5, but also does not require the use of electrical equipment, greatly saving the use cost of the filter.
