specific Embodiment 1
[0027] The present invention is an integral heat treatment heat preservation structure of a spherical storage tank, wherein:
[0028] 1. Upper and lower manhole hoops: use Ф20 round steel to make two Ф1050mm manhole hoops, and weld Ф10 round steel evenly on the hoops to fix the insulation cotton. The butt weld of the hoops is required to be full penetration welding The welds between the round steel and the upper and lower manhole hoops are fillet welds, and the weld reinforcement ≥ 6mm;
[0029] 2. Equatorial hoop: use Ф20 round steel to make an equatorial hoop with a diameter less than 1000mm of the diameter of the spherical storage tank, and weld Ф10 round steel every 350mm on the hoop to fix the insulation cotton, and the equatorial hoop is required to be docked The weld seam is a full penetration weld seam, and the weld seam between the round steel and the equator ring hoop is a fillet weld seam reinforcement ≥ 6mm;
[0030] 3. New thermal insulation cotton: use 1000mm*60...

The invention discloses an integral heat treatment insulation structure of a spherical storage tank. The integral heat treatment insulation structure of the spherical storage tank comprises an upper manhole circular hoop, a lower manhole circular hoop, an equator ring circular hoop and insulation cotton. The upper manhole circular hoop and the lower manhole circular hoop are same in structure, andare fixedly installed on the top and the bottom of the spherical storage tank. The equator ring circular hoop is further fixedly installed in the middle of the spherical storage tank. A plurality ofpieces of round steel are uniformly distributed on the upper manhole circular hoop, the lower manhole circular hoop and the equator ring circular hoop in an annular mode and used for fixing the insulation cotton. The insulation cotton is longitudinally laid between the upper manhole circular hoop and the equator ring circular hoop and between the lower manhole circular hoop and the equator ring circular hoop. The integral heat treatment insulation structure of the spherical storage tank solves the problems that when integral heat treatment insulation construction of the spherical storage tankis conducted, due to steel nail binding, the insulation cotton is seriously damaged, the usage rate is low, and the construction cost is high. A construction technology of an integral heat treatment insulation construction method of the spherical storage tank can be widely popularized in similar engineering construction in the future along with the policy requirements of energy conservation, emission reduction and green and environmentally-friendly construction in China on the basis of the construction management ideas of decreasing the cost and increasing the benefit.
Description
technical field [0001] The invention relates to the technical field of equipment manufacturing, and relates to an integral heat treatment insulation structure and a construction method of a spherical storage tank. Background technique [0002] In the past, when laying thermal insulation cotton in the overall heat treatment at the installation site of the spherical storage tank, steel nails and steel belts were generally laid on the outer surface of the spherical storage tank as a whole, and then the thermal insulation cotton was bound horizontally on the steel belt to surround the spherical storage tank body to play the role of heat preservation. . In actual construction, due to the use of steel nails and steel strips to bind the insulation cotton, the insulation cotton is seriously damaged. Generally, a set of insulation cotton can only supply the overall heat treatment of 2-3 spherical storage tanks. The long-term use of this method causes waste of resources and increases ...
