Description

Technical Field

[0001] The utility model relates to the relevant field of sludge filter press equipment, in particular to a sludge dehydration tube type tympanic membrane heating filter plate. Background Art

[0002] Sludge filter press is now used in industrial sludge dewatering in papermaking, starch, alcohol, vitamin C engineering and other industries. Plate and frame sludge filter press is a dewatering equipment that is easy to operate, stable, flexible in filtration area selection, small unit filtration area, large filtration driving force, wide range of application, low moisture content of the obtained filter cake, and strong adaptability to materials. It is a device that uses filter media to separate filter cake from water under pressure in the filter chamber composed of a filter frame, and the tympanic membrane filter heating plate is the key to the filtration effect. The current tympanic membrane filter plate has the following problems: One is that the traditional tympanic membrane filter heating plate is made of PP heat-resistant plastic by hot pressing into a whole plate with several bosses on the surface. The bosses are used to support the filter cloth. The cavity between the bosses and the filter cloth is the filter press water flow channel. Due to the poor thermal conductivity of PP heat-resistant plastic, the heating area is large, and the contact area with the filter cloth is small, the high temperature of hot water can easily deform the heating plate, or even break it, causing hot water leakage, resulting in the sludge dehydration cannot be carried out normally. In addition, the filter heating plate area is large, the hot water heating time is long, and the heating is uneven, which affects the sludge dehydration efficiency and increases the sludge dehydration energy consumption. Another is to use PP heat-resistant plastic to make the frame, the bottom plate is made of stainless steel plate, and there is a stainless steel wire mesh to support the filter cloth. Due to the low support strength of the stainless steel wire mesh, the filter cloth is compressed to make the wire mesh sink together with the sludge and block the filter press water flow channel. The filter press water is discharged with resistance, and the drainage effect is not very good, thereby affecting the dehydration efficiency. In addition, since the heating part is a basin structure, there is no diversion channel for hot water in and out, which requires increasing the hot water working time and increasing the dehydration cost.

The heating frame plate and the supporting hole plate are used as a tympanic membrane heating filter plate, which can not only greatly improve the heat resistance and rigidity of the heating filter plate, and prevent the heating filter plate from deformation and cracking, but also improve the dehydration efficiency and reduce energy consumption and dehydration costs.
