Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separator equipment, in particular to a filter press type solid-liquid separator. Background Art

[0002] The filter press solid-liquid separator uses the squeeze of the filter plate to discharge the water in the coal-water mixture through the filter medium, thereby achieving the purpose of dehydration.

[0003] Generally speaking, a filter press solid-liquid separator consists of three major parts: a frame, a pressing mechanism and a filtering mechanism. The frame is the basic component of the filter press, with thrust plates and pressing plates at both ends. The beams on both sides of the frame connect the two, and the beams are used to support the filter plates and pressing plates. The pressing mechanism includes a linear drive element and the aforementioned pressing plate. The linear drive element drives the pressing plate to move along the beam and relatively close to or away from the thrust plate to achieve the extrusion of the intermediate filtering mechanism. The material enters the filter chambers in the frame from the feed hole on the thrust plate. The solid particles are retained in the filter chamber because their particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the liquid outlet below the filter plate, thereby achieving the purpose of solid-liquid separation.

[0004] In the prior art, the filter plate has a problem of poor guiding accuracy when it is compressed for filtering or pulled apart for unloading. When the plate surface is deflected, it is easy to have a problem of deflection and movement, which affects the compression and filtration effect. At the same time, when it is pulled apart for unloading, the filter plate and the frame are prone to collision and poor operation, which poses a safety hazard to a certain extent, affecting work efficiency and the normal service life of the equipment.

[0011] In a possible implementation, the guide support frame is a right-angled trapezoidal support frame, which is connected to the compartment plate via a lower bottom and is connected to the flat roller and the vertical roller via a vertical waist.

[0012] In a possible implementation, a lightening hole is provided in the guide support frame, and the shape of the lightening hole matches the shape of the guide support frame.

[0013] Beneficial effects: Compared with the existing technology, the filter press solid-liquid separator provided by the present application sets a guide support frame on both sides of the compartment plate, and the guide support frame maintains a guiding cooperation with the beams on both sides of the frame through the guide structure.
