Description

Technical Field

[0001] This utility model relates to the field of filter press dewatering machine technology, and in particular to a hydraulic filter press dewatering machine with automatic unloading function. Background Technology

[0002] Hydraulic filter presses are used for sludge dewatering. Existing filter presses are generally multi-plate combination structures. During operation, sludge is filled into the gaps between the filter plates, and water is pumped in through a high-pressure pump to squeeze the filter cloth, thus achieving sludge compression filtration. The filtered sludge adheres to the surface of the filter cloth. Some of it falls off freely due to gravity, while some remains on the filter cloth. At this point, workers need to use tools to knock and clean the sludge to ensure the smooth operation of the next filter press. However, manual cleaning increases the labor intensity of workers and affects the automation and efficiency of sludge filter press dewatering. Therefore, we propose a hydraulic filter press with automatic unloading function to solve the above problems. Utility Model Content

[0030] The moving mechanism includes a mounting column 410, a mounting frame 420, and a drive motor 430. A lead screw 431 is provided at the output end of the drive motor 430. A sliding seat 440 is provided on the outer side of the lead screw 431. An electric telescopic rod 450 is fixed to the top of the sliding seat 440, and a mounting plate 460 is fixed to the bottom of the electric telescopic rod 450. A pulling plate mechanism is provided on the outer side of the sliding seat 440, and a discharge mechanism is provided at the bottom of the mounting plate 460. The sludge is dewatered by the drive mechanism and the filter press mechanism. The moving mechanism drives the pulling plate mechanism and the discharge mechanism to move. The pulling plate mechanism locks and positions the filter plate 240 to be cleaned and moves it to the discharge position. The electric telescopic rod 450 moves the mounting plate 460 downward, thereby moving the discharge mechanism downward. The discharge mechanism cleans the sludge adhering to the filter cloth 250. This automated sludge discharge operation replaces manual operation, reducing the labor intensity of workers and improving the automation and efficiency of the filter press dewatering operation.

[0031] Specifically, the drive mechanism includes a mounting base 310, which is fixed to one side of the frame 100 by bolts. A hydraulic rod 320 is fixed to the inner wall of the mounting base 310, and a pressure plate 330 is fixed to one end of the hydraulic rod 320. By providing a drive mechanism, during the filter pressing operation, the hydraulic rod 320 drives the pressure plate 330 to move, and the pressure plate 330 moves multiple filter plates 240 to a stacked state, so that the dewatering machine reaches a full pressure state.

[0032] Specifically, the plate-pulling mechanism includes a connecting rod 510, which is fixed to the outside of the sliding seat 440 by bolts. A sliding block 520 is fixed to the bottom of the connecting rod 510, and a positioning cylinder 530 is fixed to the top of the sliding block 520. A positioning seat 540 is fixed to the side wall of the filter plate 240. By setting up the plate-pulling mechanism, the moving mechanism drives the plate-pulling mechanism to move, moving the positioning cylinder 530 to the part of the filter plate 240 that needs to be unloaded. The positioning cylinder 530 is activated and locked with the positioning seat 540, so that the moving mechanism can drive the filter plate 240 to move through the plate-pulling mechanism.

[0033] Specifically, the bottom of the sliding block 520 is slidably connected to a support slide rail 550, and the bottom of the support slide rail 550 is fixed with a support seat 560, which is fixedly connected to the mounting side plate 210. By setting the support slide rail 550 to limit and support the sliding of the sliding block 520, the stability of the pull plate operation is ensured.

[0034] Specifically, the unloading mechanism includes a mounting block 610, which is fixed to the bottom of the mounting plate 460 by bolts. A mounting shaft 620 is rotatably connected to the inner wall of the mounting block 610. A torsion spring 630 is provided on the outer side of the mounting shaft 620, and a rotating bracket 640 is provided near the outer side of the torsion spring 630. The ends of the torsion spring 630 abut against the mounting plate 460 and the rotating bracket 640 respectively. A material-pushing roller 650 is provided at the bottom of the rotating bracket 640. By providing the unloading mechanism, the rotation of the material-pushing roller 650 scrapes and cleans the sludge adhering to the filter cloth 250, achieving automated sludge unloading, replacing manual operation, reducing the labor intensity of workers, and improving the automation and efficiency of the filter press dewatering operation.

[0035] Working Principle: During operation, the machine is controlled via the control panel 110. During the filter press operation, the hydraulic rod 320 moves the pressure plate 330, which moves multiple filter plates 240 into a stacked state, bringing the dewatering machine to a saturated state. An external sludge pump delivers sludge through the feed hole 220 and the feed ring 251 to the space between the multiple filter plates 240. Water is supplied through the water inlet pipe 241 between a pair of filter cloths 250, and the expanded filter cloths 250 perform the filter press dewatering operation on the sludge. After the filter press dewatering is completed, the drive mechanism releases the pressure on the filter plates 240, and the drive motor 430 drives the lead screw 431 to rotate. The rotation of the lead screw 431 moves the sliding seat 440, which in turn moves the plate pulling mechanism and the unloading mechanism, thus moving the fixed plate. Positioning cylinder 530 moves to the filter plate 240 where unloading is required. Positioning cylinder 530 is activated and locked with positioning seat 540, enabling the moving mechanism to move the filter plate 240 via the pulling plate mechanism and move it to the unloading position. The electric telescopic rod 450 drives the mounting plate 460 to move down, and the movement of the mounting plate 460 drives the material-pushing roller 650 to move. The rotating bracket 640 maintains an inward closing motion tendency under the action of torsion spring 630, and the rotating bracket 640 drives the material-pushing roller 650 to press the filter cloth 250 on both sides. The rotation of the material-pushing roller 650 scrapes and cleans the sludge attached to the filter cloth 250, realizing the automated unloading operation of sludge. The unloaded sludge is collected through the collection tank 120.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
