Description

Technical Field

[0001] The present invention relates to the technical field of sulfur anchoring material treatment, and particularly to a hot-melt furnace for sulfur anchoring material treatment. Background Art

[0002] When treating sulfur anchoring material, it is generally processed through a hot-melt furnace. The sulfur anchoring material and the mixture are added into the hot-melt furnace, and the materials are heated and stirred to form a slurry to be used.

[0003] Prior Art 1 (a Chinese patent with application number CN202122278781.9 and published on July 26, 2022) A sulfur melting tank device, which relates to the technical field of sulfur processing. The utility model includes a base plate, a melting furnace box is arranged on the upper side of the base plate, two cross beams are slidably matched, a heating wire is arranged inside the melting furnace box, a crucible is arranged inside the heating wire, a support frame and a cross bar are slidably matched on the upper sides of the two cross beams, a connecting rod is arranged between the support frame and the cross bar, and a cover plate is arranged on the lower side of the support frame. This application facilitates heating and melting the sulfur solid placed in the crucible through the action of the heating wire. Through the action of the slidably matched second hydraulic push rod and the support frame, it is convenient to adjust the position of the cover plate. Through the action of the connecting rod, it is convenient to adjust the height of the cover plate, so as to facilitate the cover plate to block the opening at the upper end of the melting furnace box, reducing the possibility of sulfur vapor volatilizing. Through the action of the ventilation box, it is convenient to discharge the expanded gas during the heating process. Through the action of the exhaust pipe, it is convenient to change the flow direction of the gas; Prior Art 2 (a Chinese patent with application number CN202211017913.5 and published on April 4, 2023) An energy-saving and environment-friendly hot-melt furnace, which includes a preheating box, a hot-melting box, a water tank, a hot air box, a heat conduction cylinder, a first damping spiral heat conduction pipe, an exhaust pipe, a preheating pipe, a U-shaped heat exchange pipe, a metal heat conduction rod, a second damping spiral heat conduction pipe, a tail gas filter, a blower, an electric heating pipe and an electric control valve. This application heats the interior of the hot-melting box by absorbing most of the heat of the hot air supplied by the hot air box by the heat conduction cylinder after passing through the annular cavity. Through the design of the first damping spiral heat conduction pipe, the flow rate of the hot air in the annular cavity is reduced, increasing the heat absorption efficiency of the heat conduction cylinder. The hot air discharged from the annular cavity and the tail gas generated by hot melting in the hot-melting box are sent into the preheating pipe together to preheat the raw materials in the preheating box. Through the design of the metal heat conduction rod and the second damping spiral heat conduction pipe in the preheating pipe, the flow rate of the wind is reduced. By setting a water tank and a U-shaped heat exchange pipe communicating with the preheating pipe, the residual heat in the tail gas is recovered, improving the heat utilization rate.
