Description
Technical Field
The invention relates to the technical field of solid-liquid separation, in particular to a dynamic pressurizing filter-pressing plate of a filter press.
Background
The filter press, especially the box filter press, is a common solid-liquid separation equipment, and has the advantages of high filtering pressure, large single-machine filtering area, low liquid content of filter cake, light weight of filter plate, low maintenance and operation cost, etc., so that it is widely used. The box-type filter press comprises a group of filter chambers formed by alternately arranged filter plates and filter frames, through holes are formed in the filter frames and the filter plates, a complete channel is formed after assembly, suspension, washing water and filtrate can be introduced, material liquid to be filtered is fed into each filter chamber under the pressure action of a material conveying pump, solid and liquid are separated through a filter medium, filter residues are formed on filter cloth until the filter chambers are full of the filter medium, and filter cakes are formed. In the process of filter pressing, there is a problem that filter residues block the filter cloth to affect filter pressing, for this reason, patent document 1 proposes a filter press, in which a spring and a rotatable pushing rod structure are arranged between the filter cloth and the filter pressing plate, and the spring and the pushing rod work together to enable relative movement between the filter cloth and the filter plate, thereby avoiding the situation that filter holes on the filter cloth are blocked by fixed particles to a certain extent, but due to the spring structure, the pushing rod structure can not completely cover the whole filter cloth, and because the longitudinal section area of the pushing rod is gradually reduced towards one side of the filter cloth, the end part of the pushing rod far away from the filter pressing plate is processed by chamfering, so the pushing rod is not a flexible structure, and the filter cloth is damaged by cutting and the like in the rotating process, on the other hand, the rotation of the pushing rod is realized by the fan blades arranged in the feed inlet after the feed pump inputs feed liquid through the feed inlet and drives the fan blades to rotate, when the filter is flushed, the filter chamber is not filled with liquid, so that the fan blades rotate faster, but after the filter chamber is filled with liquid, the liquid passing through the feed inlet becomes less or flows slowly, at the moment, the fan blades possibly rotate slowly or cannot rotate, at the moment, the material pushing rod cannot rotate, and therefore, the filter cloth and the filter plate cannot be separated and attached relatively. As another example, patent document 2 discloses a high-efficiency box-type filter press with dynamic water circulation, which considers the situation that sludge deposition exists in sewage during the filter pressing process, which causes uneven distribution of sludge concentration inside the sewage and increases the filter pressing load of the filter press, and therefore, a circulation pump is additionally arranged, and the sewage at the bottom is sucked into the circulation pump by using the circulation pump and then is input from the top of a container, so that the whole sewage circularly flows, and no deposition occurs, but the filter pressing cost of the filter press is further increased due to the additional arrangement of the circulation pump in the structure, and meanwhile, because the box body is of a sealed structure, only the tail part is provided with a sludge discharge port 10, the filter pressing efficiency is low, and the filter pressing effect is not ideal; still like patent document 3, it discloses an automatic pressure filter of full-hydraulic degree of depth dehydration of intelligence, it is provided with little hydro-cylinder between the left sheet frame and the right sheet frame of sheet frame, thereby use little hydro-cylinder to replace traditional spring and increased the filter-pressing room volume through little hydro-cylinder before the filter-pressing, rely on little hydro-cylinder and the mutual cooperation of master cylinder to reduce the filter-pressing room, improved the reliability of system, but when it handles the mud on the filter cloth, additionally set up a blanking mechanism, realized the separation of mud cake and filter cloth through the work of the vibrating motor in the shake blanking mechanism, its energy that needs is more.
