Problems solved by technology
However, this kind of filter press must be equipped with a large vacuum pump, and the heating structure of the filter press unit needs a lot of heat energy, which relatively increases the cost of the filter press operation, and the vacuum pump only directly discharges water vapor to the outside, resulting in a waste of heat energy resources

Embodiment Construction
[0058] Relevant present invention is to achieve above-mentioned purpose, and technical means and effect thereof adopted, enumerate feasible embodiment, and cooperate accompanying drawing, explain as follows:
[0059] First, see Figure 1 to Figure 5 As shown, it can be clearly seen from the figure that the filter press drying equipment of the present invention includes a filter press 1, a sludge slurry pipeline 2, an air pressure pipeline 3, an air blowing pipeline 4, an elutriation pipeline 5, and a heat pump 6 and a vapor compressor 7, wherein:
[0060] The frame 11 of the filter press 1 straddles a plurality of plate frames 12 with two kinds of controlled lateral displacements overlapping and leaning against each other, and cooperates with the fixed seat 14, the movable seat 15 and the hydraulic cylinder 151 to force the positioning, each The two sides of the plate frame 12 lean against each other to form an internal filter chamber 123. Each plate frame 12 is covered with ...

The invention relates to filter pressing and drying equipment utilizing functions of a heat pump and a steam compressor. The equipment comprises a filter press, a heat pump and a steam compressor, wherein a plurality of plate frames which are overlapped in displacement and lean against each other are arranged on the filter press in a spanning manner, a sludge inlet and a sewage discharge hole areformed in a filter chamber of each plate frame, and the filter chamber is communicated with an external hot air pipeline. According to the invention, hot air is conveyed into the opposite plate framesthrough the steam compressor and the hot air pipeline so as to heat sludge slurry in the filter chambers, warm waste gas is exhausted through the exhaust pipeline and the first heat exchanger of theheat pump so as to heat and increase the air temperature in the air pipeline, the hot water pipeline and the second heat exchanger are used for heating again to increase the air temperature, and thenthe steam compressor recompresses and heats the air into hot air so as to continuously supply the hot air to heat the sludge in the filter chamber into a sludge cake, so that the heat energy is recycled, the heat energy is effectively saved, the equipment cost is reduced, the operation control is convenient, and the environment-friendly requirement is met.
Description
technical field [0001] The invention relates to a filter-press drying equipment, in particular to a filter-press drying equipment utilizing the functions of a heat pump and a steam compressor. Background technique [0002] At present, filter press units for sludge and various other filter materials are placed on the track of the machine with multiple sets of filter units that can be moved and displaced separately and overlapped together. Each filter unit has filter chambers on both sides and communication For the sludge inlet, the filter chambers on both sides are respectively covered with filter cloths, and the filter cloths on both sides are connected through the sludge inlet. [0003] In the actual process of filtering sludge, all the filter units overlap and lean against the filter cloths, and the outer circumferences of the two filter cloths are closed. At the same time, the water-containing sludge is pumped and sent to the sludge inlet of the filter unit and each filte...
