Composite insulation board used for cold storage walls

Abstract

The invention discloses a composite insulation board used for cold storage walls. The composite insulation board includes a first welded plate; one end of the first welded plate is provided with a strip groove; the bottom of the strip groove is provided with a groove; the bottom of the groove is welded with a strip rod; the other end of the first welded plate is provided with a plate body; the side wall on the top of the strip groove is welded with a trapezoid shell; the middle part of the trapezoid shell is provided with a locking device; the locking device passes through the trapezoid shelland extends to the internal of the strip groove; the end, located in the trapezoid shell, of the locking device is welded with a gear; the plate body consists of a rubber layer, a sound insulation layer, a foam layer and a steel plate which are in successive arrangement from top to bottom; the internal of the foam layer is equidistantly provided with multiple heat insulating blocks; and the heat insulating blocks are fixed on the upper surface of the steel plate. The composite insulation board is reasonable in structural design and convenient in operation, and therefore, the time of operatorscan be greatly reduced, and heat insulation effects can be enhanced.

Description

technical field [0001] The invention relates to the technical field of thermal insulation board composite boards, in particular to a composite thermal insulation board used for cold storage walls. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards are also constantly improving, from the improvement of material convenience to people's diet; especially hot pot, hot pot is prevalent in Sichuan and Chongqing, until it spreads to the whole country and even further, hot pot While being sought after by people, it is also constantly innovating; there are two main soup materials for hot pot, one is clear oil, which is generally rapeseed oil, and the other is butter; those who like butter hot pot The crowd is also very large, so there are many shortcomings in the supply of butter when hot pot is popular. The preservation of raw materials or finished products of butter needs to be stored in cold storage...

Problems solved by technology

However, when the goods are stacked in the cold storage, it is inevitable that there will be a car or a forklift entering, and it is very easy to scratch when the car or forklift enters; at the same time, the traditional walls are not insulated from heat and sound, and the cold storage room is easily separated from the outside. Heat transfer occurs, which greatly affects the temperature in the cold storage, thereby increasing the cooling capacity of the compressor and reducing the service life of the compressor. At the same time, it also brings additional electricity bills to the enterprise and increases the operating cost of the enterprise.
