Conduction oil type solar drying kiln

Abstract

The invention discloses a conduction oil type solar drying kiln. The conduction oil type solar drying kiln comprises a kiln body, wherein a paraboloidal solar lighting device is installed on the top of the kiln body, a bracket is fixedly connected to the interior of the paraboloidal solar lighting device, a conduction oil pipe is connected to the upper part of the bracket, a conduction oil inlet pipe communicates with one end of the conduction oil pipe, a conduction oil return pipe communicates with the other end of the conduction oil pipe, an auxiliary electric heater and a conduction oil heat storage boiler are respectively arranged on one side of the kiln body, and one end of the conduction oil return pipe communicates with the auxiliary electric heater. Heated oil enters the conductionoil heat storage boiler so as to store heat under the circulation pushing action of a first conduction oil pump, heat in the oil is dissipated by a radiator under the circulation action of a second conduction oil pump, so that the temperature in the kiln body is increased, and the oil can be heated in rainy days by the auxiliary electric heater, so that the interior of the kiln body is heated anddried.

Description

technical field [0001] The invention relates to the technical field of drying kilns, in particular to a thermal oil type solar drying kiln. Background technique [0002] Drying kiln is a large-scale drying equipment used in industrial production. It is widely used in cement industry, metallurgical industry, wood pile drying, brick and tile drying and other production. The reaction temperature of the kiln body is relatively high in the production process of the drying kiln, so the acquisition, monitoring and control of process parameters such as the kiln body temperature are important links to ensure the roasting quality. The drying kiln is mainly composed of the main body of the drying furnace, the drying room, the hot air steam transmission pipeline, the recovery pipeline, the gate valve and the temperature and humidity instrument. The main body of the drying furnace is mainly composed of furnace door and furnace, heat exchange system, steam generating device, combustion-s...

Problems solved by technology

[0003] Although the ordinary solar drying kiln has a certain heating effect by using solar energy during the day, it cannot use the solar heat energy stored during the day at night. In order to maximize the use of solar heat energy, a thermal oil type solar drying kiln is provided. It is necessary to solve the above problems
