Abstract
The subject of the invention is a method for the manufacture of briquettes from comminuted straw, as well as a device to manufacture briquettes from comminuted straw. The method consists in that comminuted straw is compressed in a continuous process using a screw-type extruder until the material reaches a temperature at which the material after pressing solidifies to a density exceeding 1.3 g/cm 3. The device has a screw (3) composed of three segments of decreasing helix pitches toward the outlet. The forming die (8) is housed in a tank (11) connected through a water system (12) to a cooler (13). The cooling system has a temperature sensor (17) installed, said sensor being part of the pump supply circuit (15).
Claims2
A device for the manufacture of briquettes from comminuted straw, having a screw supported on bearings at its base, composed of segments of different helix pitches disposed in a barrel ended with a forming die, downstream which die a guide is disposed, and above the barrel there is a raw material hopper, characterized in that the screw (3) consists of three segments of decreasing helix pitches toward the outlet, while the forming die (8) is housed in a tank (11) connected through a water system (12) to a cooler (13) which has a fan (14), and a chute (18) at barrel (1) is connected with a hopper (19) inside which there is a screw feeder (20) driven by a motor (21), and on an inclined wall of the hopper (19) a rotary scraper (22) is mounted whose arm ends mate the helix of the screw feeder (20).
The device according to claim 2, characterized in that in the tank (11) there is installed a temperature sensor (17) which is part of the pump supply circuit (15) of the water system (12).
