Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a sludge filter press device. Background Art

[0002] A filter press is a machine that applies mechanical force on one side of the filter medium to achieve filtration. It is mainly used for solid-liquid separation of sludge. The sludge filter press is mostly used for dehydrating industrial sludge in industries such as papermaking, starch, alcohol, and vitamin C engineering. At present, there are still some shortcomings in the traditional sludge filter press. After the sludge filter press has completed the dehydration of the filter plate, it is necessary to separate the filter plates one by one through the mobile device, and then the sludge falls off naturally. Due to the strong viscosity of the sludge, the filter plate still sticks to the filter plate after dehydration, so it is necessary to manually clean it one by one, thereby increasing the labor intensity of the workers. To solve the above problems, a technical solution is disclosed in Patent No.: CN202321351375.3, but the technical solution still has some problems when it is used. When the technical solution is used, if it is necessary to separate the mud cake on the filter press plate, it is necessary to use an external mechanism when the filter press plate is separated to clean it. This operation invisibly causes the equipment to waste time when it is working, thereby causing the problem of reduced working efficiency of the equipment.

[0003] Based on this, the utility model designs a sludge filter press device to solve the above problems. Utility Model Content

[0007] Preferably, the lifting mechanism includes a threaded rod and a drive motor. The mounting frame is rotatably connected with a threaded rod. Two threaded rods are transmission-connected. One of the threaded rods is equipped with a drive motor, and the movable plate is threadedly connected to the threaded rod.

[0008] Preferably, a slide groove is provided on the inner side of the mounting frame, and the movable plate is slidably connected in the slide groove.

[0009] Preferably, the separation mechanism comprises a receiving groove, a first spring and a limiting rod, the filter press plate is provided with a receiving groove, a first spring is fixedly connected between every two of the receiving grooves, and a limiting rod is provided on the inner side of the first spring.

[0010] Preferably, the guide plate is arc-shaped, a smooth alloy layer is provided on the surface of the guide plate, and the guide groove is vertically opened.

[0011] Preferably, the diameter of each of the path beads is different.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model pours the mixed liquid to be filtered between the filter press plates, and then controls the hydraulic rod to extend. At this time, the guide groove on the filter press plate contacts the smooth surface on the upper side of the guide rod. At the same time, as the hydraulic rod pushes, multiple filter press plates approach each other, so that the first spring in the separation mechanism is compressed, and at the same time, the first spring enters the receiving groove. As the filter press plates gradually approach each other, the filter press plates discharge the sewage inside them, so that the mud cake remains between every two filter press plates. When the filter press plates have been filtered for a certain period of time, the driving motor is controlled to rotate, and at this time the threaded rod rotates, thereby causing the movable plate to move up. When the movable plate moves up, the filter press plate moves up at the same time. At this time, the slide plate slides inside the fixed shell, and the lower part of the guide groove and the lower side of the guide rod Contact, and then control the hydraulic rod to retract. When the hydraulic rod retracts, the guide plate and the path bead come into contact. At this time, the path bead is squeezed, thereby causing the filter press plate to be displaced. At the same time, the length of the second spring changes. When the path bead and the guide plate are separated, the filter press plate is vibrated by the rebound of the second spring as a motive force, and then the equipment vibrates the filter press plate to separate the mud blocks during the process of separating each filter press plate, thereby making the equipment more convenient to separate from the mud blocks, and at the same time increasing the cleaning efficiency of the equipment, reducing the shutdown steps of the equipment, and further improving the practicability and practicability of the equipment. At the same time, when the filter press plates are separated, the separation of the mud blocks can be completed, which further reduces the space occupied by the equipment and further improves the practicability of the equipment.

At the same time, when the filter press plate 9 is separated, the separation of the mud blocks can be completed, which further reduces the space occupied by the equipment and further improves the practicability of the equipment.
