Patent ID: 8235705

Claim:
A sulfur concrete substance producing apparatus, comprising: a material hopper heated to a temperature within a preset temperature range of which a lower limit is equal to or above a melting point of sulfur, which stores a sulfur-containing material in a melt state on the inside thereof; a pressure generator to pull the sulfur-containing material out of the material hopper and into a cylinder heated to a temperature within the preset temperature range, and thereafter, to push the sulfur-containing material out of the cylinder under predetermined pressure; an opening and closing plate provided at each of a pull port and a push port, said pull port allowing for the pulling of for pulling the sulfur-containing material out of the material hopper and into the cylinder, and said push port allowing for the pushing of the sulfur-containing material out of the cylinder, said plates interlockingly moving to thereby alternately open and close the pull port and the push port; an injection hose whose base end is connected to the push port for the sulfur-containing material from the cylinder, which is heated to a temperature within the preset temperature range, and in which the sulfur-containing material flows; a mold whose injection port of the sulfur-containing material is connected to the other end of the injection hose, which has therein a cavity in communication with the injection port and is able to be hermetically sealed, and an air-release hole in communication with the cavity, and the mold being heated to a temperature within the preset temperature range; and an interrupting mechanism provided for the injection port in the mold, which closes the injection port after the sulfur-containing material is fully injected into the cavity.
