Example 3

On the basis of embodiment 2, as shown in fig. 9 to 11, the scraping assembly 7 is further included, the scraping assembly 7 is disposed on the switching assembly 3, the scraping assembly 7 is used for scraping off solid impurities sticky on the filter frame 3101, the scraping assembly 7 includes a second slotted frame 71, a column clamping frame 72, a scraper 73, a fourth spring 74, a blocking frame 75, a fifth spring 76 and a guide plate 77, the second slotted frame 71 is welded at the top end of the sliding frame 35, the column clamping frame 72 is slidably connected to the second support frame 31, the column clamping frame 72 is in spacing fit with the second slotted frame 71, the column clamping frame 72 is in contact with the filter frame 3101, the scraper 73 is slidably connected to the column clamping frame 72, the filter frame 3101 is in contact with the scraper 73, the scraper 73 is used for scraping off the solid impurities sticky on the filter frame 3101, the fourth spring 74 is connected to the scraper 73, one end of the fourth spring 74 far from the scraper 73 is connected to the column clamping frame 72, a blocking frame 75 is connected to the second support frame 31 near the column clamping frame 72 in a lifting manner, the blocking frame 75 is used for blocking the bottom of the second support frame 31, a fifth spring 76 is connected between the blocking frame 75 and the second support frame 31, and a guide plate 77 is arranged on the second support frame 31.

When the first slotting frame 38 and the devices on the first slotting frame are reciprocated left and right, the sliding frame 35 drives the second slotting frame 71 to reciprocate left and right, the second slotting frame 71 drives the column clamping frame 72 and the scraper 73 to reciprocate up and down, and the scraper 73 reciprocates up and down to scrape off solid impurities stuck on the filter frame 3101, so that the solid impurities are prevented from blocking meshes of the filter frame 3101. When the column clamping frame 72 moves downwards, the blocking frame 75 is pushed to move downwards, the blocking frame 75 does not block the bottom of the second support frame 31 any more, the filtering frame 3101 pushes the scraper 73 to move towards the direction away from the support frame 1, the scraper 73 pushes solid impurities out of the second support frame 31, and the solid impurities slide downwards through the guide plate 77. When the column clamping frame 72 and the scraper 73 move downwards, the column clamping frame 72 is separated from the blocking frame 75, the compressed fifth spring 76 resets to drive the blocking frame 75 to move upwards to reset so as to block the bottom of the second support frame 31, and the compressed fourth spring 74 resets to drive the scraper 73 to move towards the direction close to the support frame 1 to reset.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
