High-temperature spiral feeder

Abstract

The invention relates to the field of material conveying equipment, specifically a high-temperature spiral feeder. The high-temperature spiral feeder comprises a motor reducer, a cooling section, a heat insulation section and a high temperature feeding section which are connected in sequence, wherein the output shaft of the motor reducer penetrates the cooling section and then is connected to a spiral conveyer main shaft in the high temperature feeding section through a shaft coupling in the heat insulation section; the cooling section comprises a cooling box, a temperature sensor arranged inthe inner cavity of the cooling box, a semiconductor cooler arranged on the wall of the cooling box, and a temperature controller arranged outside the cooling box; a first heat insulation gasket is clamped between the cooling box and the motor reducer; a second heat insulation gasket is clamped between the cooling box and the heat insulation section; the signal output of the temperature sensor isconnected to the temperature controller, and the signal output of the temperature controller is connected to the semiconductor cooler; and the on-off of the semiconductor cooler can be controlled by the temperature controller through the temperature signal measured by the temperature sensor. The high-temperature spiral feeder has a compact structure, does not require water cooling, and can guarantee the continuous transportation of high temperature materials.

Description

technical field [0001] The invention relates to the field of material conveying equipment, in particular to a high-temperature screw feeder. Background technique [0002] In industrial production, high-temperature screw feeders are needed to transfer high-temperature materials between heating furnaces or between heating furnaces and external production lines. In order to ensure normal operation at high temperature, the feeding section of the high-temperature screw feeder often uses high-temperature-resistant materials and bearings, but the motor reducer that drives the auger to rotate and feed cannot meet the high-temperature-resistant requirements. Some high-temperature screw feeders separate the motor and reducer from the feeding section, and drive the rotation of the screw auger through a chain or gear. Such a structure will cause the volume of the whole high-temperature screw feeder to be large and the transmission to be unstable. There are also some high-temperature s...

Problems solved by technology

Although this structure is compact, the water seal of the rotating shaft at high temperature is relatively complicated, and it needs to continuously add water for cooling, which wastes water resources and high operating costs.
