Thermal-insulation storage for finished asphalt

Abstract

A thermal-insulation storage for finished asphalt comprises a storage body and a discharge door. The discharge door is disposed at a discharge outlet of the storage body. The discharge door is opened or closed to control discharging and closing of the storage. The thermal-insulation storage for finished asphalt is characterized in that a thermal insulation device and a heating device are disposed on the wall of the storage body. The thermal insulation device comprises a frame and heat transfer oil, the frame is attached to the wall of the storage body, and the heat transfer oil is filled into the frame. The frame is provided with an oil filling hole, an observation hole and an oil discharging hole. A first stopper is fitted to the observation hole. A second stopper is fitted to the oil discharging hole. The heating device comprises a heater extending into the frame and a thermostatic switch in linkage with the heater. The heater heats the heat transfer soil within a set temperature range set through the thermostatic switch. The thermal-insulation storage for finished asphalt is effective in heating and thermal insulation and guarantees production continuousness of a mixing plant by means of efficient thermal insulation of thermal insulation cotton and reliable heat carrying of the heat transfer oil, and meets the construction requirement on long-term storage of finished asphalt.

Description

technical field [0001] The invention relates to a thermal insulation type asphalt product silo, in particular to a finished product silo capable of heating and insulating the asphalt finished material in the silo. Background technique [0002] With the increasingly fierce competition in the infrastructure market, construction units such as highways and municipalities have continuously improved the requirements for flexible control of the production process of asphalt mixing equipment. Widespread attention from all parties. [0003] At present, most asphalt mixing equipment adopts real-time start-up and compact material receiving vehicles. When the material receiving speed of the material receiving vehicle cannot meet the capacity of the mixing plant, it is necessary to shut down the entire mixing plant from time to time, which seriously affects the working life and quality of the mixing plant. Continuity of production; for this purpose, a finished product silo is usually in...

[0003] At present, most asphalt mixing equipment adopts real-time start-up and compact material receiving vehicles. When the material receiving speed of the material receiving vehicle cannot meet the capacity of the mixing plant, it is necessary to shut down the entire mixing plant from time to time, which seriously affects the working life and quality of the mixing plant. Continuity of production; for this purpose, a finished product silo is usually installed outside the mixing device, and the finished asphalt material after mixing is sent to the finished product silo by a transport truck. The finished product silo is usually equipped with an insulation unit to avoid The temperature of the material drops and th
