Abstract
The invention discloses a pressure dewatering machine for sludge, which comprises a cylinder body and a feeding piston arranged in a sludge cavity inside the cylinder body, wherein the end part of the feeding piston is provided with a feeding cylinder; the cylinder body is connected with a filtration chamber; the sludge cavity of the cylinder body is communicated with the inner cavity of the filtration chamber; the cylinder body is provided with a sludge feeding port communicated with the sludge cavity inside the cylinder body; outer filters are arranged in the inner cavity of the filtration chamber, and are combined and connected into a hollow filtration cavity by a plurality of outer filter discs; the filtration cavity is communicated with the sludge cavity of the cylinder body; an outer water collection chamber is formed between the outer filters and the wall of the filtration chamber; the side wall of the filtration chamber is provided with a water outlet hole A communicated with the outer water collection chamber; an unloading piston is movably and tightly connected at one end symmetrical with the connection end of the filtration chamber and the cylinder body by a sealing endcover; and the unloading piston is connected with an unloading cylinder. By using the inner and outer filters to carry out bidirectional high-pressure extrusion on the moisture in the sludge, the invention improves the sludge dewatering efficiency.
Description
technical field [0001] The invention relates to a sludge dewatering device, in particular to a sludge pressure dehydrator. Background technique [0002] At present, my country's sewage treatment enterprises produce a large amount of sludge with high water content in the process of sewage treatment. There are a large amount of perishable organic matter, bacteria, viruses and heavy metals in the sludge. These sludge must be dehydrated for subsequent treatment and disposal. . However, the sludge dewatering equipment currently used by sewage treatment enterprises in my country: drum centrifuge, belt dehydrator and plate and frame filter press, due to structural limitations, it is difficult to increase the pressure and centrifugal force of the equipment, and the moisture content of the sludge after dehydration is 75%. -85%, regardless of subsequent disposal methods such as landfill, composting and incineration, the cost of disposal is very high. Therefore, how to further reduce t...
