Embodiment Construction

[0018] A heat supply and heat preservation method for a finished sand and gravel aggregate yard in an alpine region, comprising the following steps:

[0019] Step 1: Lead the heat supply pipeline 1 from the heat source to the finished sand and gravel aggregate yard 2 .

[0020] Step 2: The radiator fin device 3 is arranged at the top of the corridor 4 of the finished sand and gravel aggregate stockyard 2, and the horizontal position of the radiator fin device 3 is arranged in the dead volume area of ​​the aggregate stockyard. The center is arranged in two rows; the living volume area 10 of the finished sand and gravel aggregate storage yard 2 under the jurisdiction of each discharge port 6 is provided with four sets of heat sink devices 3 radially and evenly distributed for heating.

[0021] Step 3: Install a steam exhaust pipe 7 at the discharge port 6 to form a heating hopper, pass through the discharge hopper aggregate, and keep the temperature above 0°C.

[0022] Step 4: ...

Abstract

The invention relates to a heat supply and heat preservation method for a finished sandstone aggregate yard in an extremely frigid zone, which comprises the following steps: leading out a heat supply pipeline from a heat source to the finished sandstone aggregate yard; performing elevation arrangement on radiating fin devices at the top part of the gallery of the finished sandstone aggregate yard, horizontally arranging the radiating fin devices in the dead-volume zone of the finished sandstone aggregate yard, and arranging the radiating fin devices in two rows by taking a discharging hole as the center; arranging a steam rack pipe at the position of the discharging hole to form a heat supply bucket; and feeding to a discharging belt through vibration discharging equipment. The heat supply and heat preservation method for the finished sandstone aggregate yard in the extremely frigid zone is economic, convenient, fast, safe and reliable.

Description

technical field [0001] The invention relates to a heat supply and heat preservation method for a finished sand and gravel aggregate storage yard in an alpine region. Background technique [0002] The heating and heat preservation of the finished sand and gravel aggregate yard in the alpine region is used to prevent the aggregate from freezing and ensure normal discharge. The strong storage adjustment capacity of the sand and gravel processing system can avoid production during extremely cold periods; however, the sand and gravel processing system yard that supplies the aggregate of the mixing system must be supplied in time with the production of the mixing system. When the aggregate is stored in the yard, the aggregate is relatively static and maintains a certain moisture content, which is easy to freeze and cannot be discharged smoothly. In order to ensure normal material supply, it is necessary to provide heat and heat preservation to the finished aggregate yard. Conte...
