Problems solved by technology
The disadvantage of this filter plate is the use of inlaid sealing rings and press diaphragms, resulting in complex structures and high prices
In addition, high-pressure water is required for diaphragm pressing during the filtration process, which leads to complicated piping system and prolonged working cycle
In particular, the press diaphragm and sealing strip are often damaged and need to be replaced; not only the cost of spare parts is high, but also the workload of replacement is large, and the production time is delayed for a long time

Embodiment Construction
[0012] As shown in Figure 1, filter press 10 of the present invention has opening and closing compression mechanism 11, and this mechanism has lower pressing plate 12, and the upright column 13 that is fixedly connected on lower pressing plate 12 both sides (in figure only sees upright column 13 on one side ), the upper pressing plate 14 that can be lifted along the column drives the transmission mechanism 15 that the upper pressing plate lifts. The filter press 10 also has a filter belt traveling mechanism 16, two filter plates 17 and filter belts 18 in a pulled state between the lower platen 12 and the upper platen 14, and two filter plates 17' that have not been pulled apart . Below the bottom filter plate 17' is a base plate 19, and above the uppermost filter plate 17 is a top plate 20.
[0013] Such as figure 2 Shown, filter plate 17 of the present invention and filter plate 17 ' are made of inverted concave body 21, elastic sealing frame 22 and filter plate 23. The wa...

The invention relates to the field of dissociating the solid and liquid, which in detail relating to a filtering board of the pressing filter. The existing flat filtering board possesses pressing sieve and the sealing joint strip inserted on the sealing surface of the filtering cake cavity, and the structure is complex. The pressing sieve and sealing joint strip need changing constantly in the using process, which is time and labor waste and delays the production. The flat filtering board includes inversed concave, water filtering board set on the concave and flexible sealing rim around the water filtering board. The flat filtering board is characterized by the simple structure, long durability and convenient unpacking and serving, which can increase the working rate of the pressing filtering device largely, improve the production ability and deduce the production cost.
Description
technical field [0001] The invention relates to the field of solid-liquid separation, in particular to a filter plate of a filter press. Background technique [0002] A well-known filter press has a filter plate opening and closing mechanism and a compacting mechanism, a plurality of horizontal filter plates and filter belts arranged vertically between the compacting mechanisms, and a filter belt traveling mechanism. The filter plate has components such as a filter frame, a filter plate, a water filter plate embedded in the filter plate, a pressing diaphragm assembled between the filter plate and the filter frame, and a sealing strip embedded on the sealing surface around the filter frame. When filtering, the filter plate and the filter belt are pressed against each other under the action of the pressing mechanism to form a closed filter cake cavity, a filtrate cavity and a squeezed water cavity. The suspension enters the filter cake cavity through the inlet of the filter c...
