[0030] Reference Figure 1 As shown, the utility model provides a technical solution: a sludge filter press dewatering treatment device, comprising two supporting legs 1, a filter press frame 2 is fixedly mounted on the upper surface of the two supporting legs 1, a plurality of filter holes 10 are evenly opened on the side wall of the filter press frame 2, a mounting frame 7 is fixedly connected to the side wall of the filter press frame 2, a motor 6 is fixedly mounted on the inner side of the mounting frame 7, a screw rod 5 is rotatably mounted inside the filter press frame 2, a push plate 4 is slidably connected to the inner side of the filter press frame 2, the push plate 4 and the side wall of the screw rod 5 are threadedly connected, the output end of the motor 6 and the screw rod 5 are fixedly connected, a replacement structure 8 is provided on the inner side of the filter press frame 2, and a discharge structure 9 is provided on the lower surface of the filter press frame 2.

[0031] The specific settings and functions of the replacement structure 8 and the discharging structure 9 will be described in detail below.

[0032] Reference Figures 1-4 As shown, in this embodiment: the replacement structure 8 includes extraction holes 89 opened on both sides of the filter press frame 2, and a gauze 81 is slidably installed inside the two extraction holes 89. The side wall of the filter press frame 2 is fixedly connected to two rectangular blocks 86, and two slide bars 87 are slidably connected inside the rectangular blocks 86. The other ends of the two slide bars 87 are fixedly connected to a rectangular bar 82, and the surface of the rectangular bar 82 is evenly fixedly connected with a plurality of barbed hooks 83. When it is necessary to replace the gauze 81, the gauze 81 is first passed through the extraction holes 89 to achieve the preliminary installation of the gauze 81. At this time, the two sides of the gauze 81 are respectively put on the surface of the two rows of barbed hooks 83 to achieve the preliminary installation of the gauze 81.

[0033] The internal thread of the rectangular block 86 is connected to a driving rod 88, which is rotatably connected to the inside of the rectangular bar 82. When the driving rod 88 is rotated, the driving rod 88 will drive the rectangular bar 82 to move. The internal sliding connection of the filter press frame 2 is a pressing plate 84, which passes through the extraction hole 89. The pressing plate 84 will apply pressure to the gauze 81 inside the extraction hole 89, making it easier to fill the gap between the extraction hole 89 and the gauze 81 and avoiding the subsequent sludge from being squeezed out from the inside of the extraction hole 89. The internal thread of the pressing plate 84 is connected to a bolt 85, which is rotatably connected to the inside of the filter press frame 2. When the bolt 85 is rotated, the bolt 85 will drive the pressing plate 84 to move.

[0034] Reference Figure 1-Figure 3 and Figure 5 As shown, the discharge structure 9 includes a discharge port 96 formed on the lower surface of the filter press frame 2. Four limiting bars 92 are slidably connected to the bottom of the filter press frame 2, with a blocking plate 91 fixedly connected between the four limiting bars 92. The blocking plate 91 slides out from the inside of the discharge port 96, allowing the removal of sludge from the blocking plate 91 and facilitating subsequent processing of the squeezed sludge. A positioning block 93 is fixedly connected to the bottom surface of the filter press frame 2, with a blocking frame 94 slidably connected to the inside of the positioning block 93. When the blocking frame 94 inside the positioning block 93 is pulled and slides out from under the blocking plate 91, the blocking plate 91 slides out from the inside of the discharge port 96. A spring 95 is fixedly connected between the blocking frame 94 and the positioning block 93. When the blocking frame 94 is released, the spring 95 forces the blocking frame 94 to block the blocking plate 91, locking the blocking plate 91.

[0035] Working principle: when the gauze 81 needs to be replaced, the gauze 81 is first passed through the extraction hole 89 to achieve the preliminary installation of the gauze 81. At this time, the two sides of the gauze 81 are respectively put on the surface of the two rows of barbed hooks 83 to achieve the preliminary installation of the gauze 81. At this time, the driving rod 88 is rotated, and the driving rod 88 will drive the rectangular bar 82 to move, wherein the sliding bar 87 slides inside the rectangular block 86 to limit the moving direction of the rectangular bar 82. By driving the two rectangular bars 82, it is convenient to tighten the gauze 81 after replacement, and the stability of the gauze 81 during use is improved. At this time, the bolt 85 is rotated, and the bolt 85 will drive the pressure plate 84 to move, and the pressure plate 84 will press the extraction hole 89 The inner gauze 81 applies pressure, which facilitates the filling of the gap between the suction hole 89 and the gauze 81, and avoids the subsequent sludge being squeezed out from the inside of the suction hole 89. After discharging sewage into the inside of the feed port 3, the motor 6 is started, and the motor 6 will drive the screw 5 to twist, which can realize the driving work of the push plate 4. The water will be squeezed out through the gauze 81 and the inside of the filter hole 10, thereby realizing the dehydration of the water in the sludge. By setting up the replacement structure 8, the regular and stable replacement of the gauze 81 is facilitated. The replaced gauze 81 can be stably mounted on the surface of the barbed hook 83, avoiding the phenomenon that the traditional gauze 81 is easy to loosen after replacement, and improving the stability of the gauze 81 in the filter press after use.

[0036] After filtering the water in the sludge, pull the baffle 94 inside the positioning block 93. When the baffle 94 slides out from under the baffle 91, the baffle 91 will slide out from the inside of the discharge port 96. At this time, the sludge on the baffle 91 can be removed, which is convenient for the subsequent treatment of the squeezed sludge. After the sliding baffle 91 is retracted to the inside of the discharge port 96, the baffle 94 is released. The baffle 94 will be blocked under the baffle 91 by the elastic force of the spring 95, which can realize the locking of the baffle 91 and facilitate the normal use of the filter press frame 2. By setting the discharge structure 9, the flexible treatment of the sludge after filtration is facilitated, and the performance of the filter press device is further improved.
