[0027] Example 1: Please refer to Figure 1-Figure 4A high-efficiency vertical filter press for sewage treatment, comprising a filter press box 1, wherein the filter press box 1 is provided with anti-skid support seats 17 on both sides thereof by bolt connection, wherein the anti-skid support seats 17 are used to lift the filter press box 1, wherein eight filter press plates 2 stacked in a vertical direction are slidably provided in the filter press box 1, wherein a connecting rod 3 is fixedly connected to the rear side of the filter press plate 2 by welding, wherein two sliding plates 5 staggered in a front-to-back arrangement are slidably provided on the filter press box 1, wherein eight guide grooves are provided on the sliding plate 5, wherein the eight connecting rods 3 slide in the eight guide grooves respectively, and the eight filter press plates 2 can be stacked and unfolded by moving the sliding plate 5 left and right, and the rear side of the filter press box 1 is provided with a connecting rod 3. A protective shell 4 is fixedly connected by bolt connection, and the protective shell 4 is used to seal the rear side of the filter press box 1. A double-axis motor 6 is arranged on the upper rear side of the filter press box 1. The left and right output shafts of the double-axis motor 6 are connected to the first threaded rod 7 through a coupling. The first threaded rod 7 is threadedly connected to the sliding plate 5. The operation of the double-axis motor 6 can drive the first threaded rod 7 to rotate, so that the sliding plate 5 moves left and right. The right side of the filter press box 1 is connected and connected to a one-way water inlet pipe 8, and the bottom of the filter press box 1 is connected and connected to two drainage pipes 9 that are symmetrically distributed on the left and right. A scraper assembly is arranged on the filter press box 1, and the scraper assembly is used to scrape impurities on the filter press plate 2.

[0028] See also Figure 6-Figure 8 The scraper assembly includes a drive motor 14, which is arranged on the front side of the protective shell 13. The output shaft of the drive motor 14 is connected to a second threaded rod 15 through a coupling. The operation of the drive motor 14 can drive the second threaded rod 15 to rotate. The second threaded rod 15 is threadedly provided with a scraper frame 16. The second threaded rod 15 rotates to move the scraper frame 16 to clean the filter plate 2. Eight slide grooves 18 are opened on the front side of the filter press box 1. The scraper frame 16 slides horizontally on the eight slide grooves 18, and the scraper frame 16 is guided by the slide grooves 18. Eight discharge grooves 23 are opened on the left side of the filter press box 1, and the eight discharge grooves 23 correspond to the eight filter press plates 2 one by one. A fixed frame 21 is fixedly connected to the left side of the filter press box 1 by welding, and a discharge pipe 22 is provided on the left side of the fixed frame 21 by bolt connection. The discharge pipe 22 is used to discharge impurities on the filter press plate 2. A fourth threaded rod 25 is threadedly provided on the top of the fixed frame 21, and a baffle 24 is fixed to the fourth threaded rod 25. The baffle 24 slides longitudinally in the fixed frame 21, and the discharge pipe 22 can be blocked by rotating the fourth threaded rod 25 to move the baffle 24 downward.

[0029] When in use, sewage is input into the filter press box 1 through the one-way water inlet pipe 8, and the double-axis motor 6 is started at the same time to move the two sliding plates 5 inwardly. At this time, the connecting rod 3 moves along the guide groove to make the eight filter press plates 2 tightly stacked, and then the sewage enters the filter press plate 2, which intercepts the internal impurities and presses the impurities into blocks to achieve solid-liquid separation, and the water filtered out by the filter press plate 2 is discharged through the drain pipe 9. When it is necessary to discharge the block impurities, the double-axis motor 6 is controlled to move the sliding plate 5 outward, and each filter press plate 2 is reset accordingly, and then the fourth threaded rod 25 is rotated to move the baffle 24 down and align with the discharge pipe 22, and then the drive motor 14 is started, and the drive motor 14 drives the second threaded rod 15 to rotate, so that the scraper frame 16 moves to the left to push out the impurities on the filter press plate 2 and scrape off the impurities adhering to the filter press plate 2, so as to clean the filter press plate 2, and finally the pushed out impurities are discharged by the discharge pipe 22.

[0030] Example 2: Based on Example 1, please refer to Figure 5 A protective shell 13 is provided on the front side of the filter press box 1 by means of bolt connection, a third threaded rod 20 is threadedly provided in the middle of the protective shell 13, a sealing plug plate 19 is fixedly connected to the third threaded rod 20, and the sealing plug plate 19 can be moved forward by rotating the third threaded rod 20 to block the slide groove 18.

[0031] During the filter pressing operation, the sealing plug plate 19 is inserted into the slide groove 18 to close the filter press box 1 to prevent water leakage in the filter press box 1 and provide a sealed environment for subsequent operations. When discharging operation is required, the third threaded rod 20 is rotated to move the sealing plug plate 19 forward and out of the slide groove 18 to make room for the scraper frame 16 to move.

[0032] See also Figure 3 A support frame 10 is provided on the top of the filter press box 1 by bolt connection, and two electric push rods 11 are provided on the support frame 10 and are symmetrically distributed on the left and right. The movable rods of the two electric push rods 11 are jointly provided with a pressure plate 12, and the pressure plate 12 is located in the filter press box 1. The filter press plate 2 can be squeezed by driving the pressure plate 12 downward through the operation of the electric push rods 11.

[0033] When the filter press plate 2 performs the filtering operation, the electric push rod 11 is started, and the electric push rod 11 drives the pressing plate 12 to move downward to squeeze the filter press plate 2, thereby increasing the pressure on the filter press plate 2, so that the filter press plate 2 can fully press out the water in the impurities, thereby improving the filtering effect.
