Discharging door for stock bin of finished asphalt concrete

Abstract

The invention relates to a discharging door for a stock bin of finished asphalt concrete, in particular to a discharging door capable of heating the asphalt concrete in the stock bin. The discharging door is arranged below a discharge opening of the stock bin of the finished asphalt concrete through a fixing shaft; and a driving mechanism, which is connected with the discharging door so as to control the discharging door to be opened or closed, is arranged on the stock bin for the finished asphalt concrete. The discharging door is characterized in that a heating system and a temperature-controlled device for controlling the heating system to work are arranged on the discharging door; a cavity for accommodating heat conducting oil is formed in the discharging door; the heating system comprises heat conducting oil arranged in the cavity and a heater communicated with the inside of the cavity; and the temperature-controlled device is used for controlling the heater to heat the heat conducting oil within a set temperature value. According to the discharging door, by means of reliable heat carrier performance of the heat conducting oil, the integral quality of heating is effectively ensured, and a favorable heat insulating effect is obtained; meanwhile, production continuousness of a mixing plant is ensured; a receiving cart can be used for receiving materials at variable intervals according to the requirement; and the construction requirement for storing the finished asphalt for a long time is met.

Description

technical field [0001] The invention relates to a discharge door of a finished asphalt concrete silo, in particular to a discharge door capable of heating the asphalt concrete in the silo. Background technique [0002] With the increasingly fierce competition in the infrastructure market, construction units such as highways and municipalities have continuously increased their requirements for flexible control of the production process of asphalt concrete mixing plants. increasingly received widespread attention. [0003] At present, most asphalt concrete mixing plants use 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 of the mixing plant. and the continuity of production; for this purpose, a finished product silo is usually installed outs...

Problems solved by technology

[0003] At present, most asphalt concrete mixing plants use 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 of the mixing plant. and the continuity of production; for this purpose, a finished product silo is usually installed outside the mixing device, and the finished asphalt concrete material after mixing is sent to the finished product silo by a transport truck, and the finished product silo is usually equipped with an insulation unit to avoid The temperature of the finished asphalt material drops and the viscosity increases to cause agglomeration. However, the discharge door of this kind of finished product silo is mostly air-heated, which cannot effectively guarantee the overall quality of heating, and the insulation effect is not good. The function of the finished product silo is similar to that of production If the transition warehouse in the process cannot be effectively insulated, it will not be able to meet the construction requirements for long-term storage of asphalt finished materials
