Sludge composite fuel extrusion molding equipment

Abstract

The present invention relates to a sludge composite fuel extrusion molding apparatus, comprising: a computer monitoring system including at least one operating interface and one monitoring interface; an automatic feed speed adjustment device connected to the computer monitoring system, including a feed inlet, a conveyor, a first pressure sensor, and a discharge outlet, wherein the feed inlet receives material and the conveyor transports the material, the first pressure sensor detects and transmits the pressure value of the conveyor to the computer monitoring system, causing the conveyor to transport the material out of the discharge outlet at a predetermined rate; and a heating device connected to the computer monitoring system, including an input terminal and a output terminal. The output end is connected to the discharge port. A predetermined temperature is set by the operation interface of the computer monitoring system. When the material passes through the heating device, the material is heated to the predetermined temperature, which reduces the viscosity of the material, and the material is output from the output end. The output end is also a compression device, which includes a compression die and a pressure control module connected to the compression die. The compression die is located at the output end and includes a plurality of channels. The material enters each of the channels of the compression die. The pressure control module compresses the material through each of the channels with a predetermined pressure to form a fuel block and output it. The fuel block has a predetermined density and a predetermined strength.
