Description

Inflatable flexible ventilation pipe and ventilation pipe assembly

Technical Field

The invention belongs to the field of ventilation or inflation devices, and particularly relates to an inflatable flexible ventilation pipe and a ventilation pipe assembly.

Background

In order to refrigerate and heat a factory building and a workshop with large span and large space, for example, a central air conditioner is installed in an animal farm, the central air conditioner comprises an outdoor unit capable of refrigerating or heating, a fan coil device positioned indoors and a water conveying pipeline for communicating the outdoor unit with the fan coil device, and the fan coil device comprises a fan capable of sucking air and a heat exchange sheet capable of exchanging heat; secondly, because the span of the farm is large and the space is large, a plurality of ventilating ducts are uniformly hung in the farm, one end of each ventilating duct is an air inlet, and the other end of each ventilating duct is an air blowing port; secondly, the fan coil device is installed in the mouth position of blowing of air pipe, therefore, the fan coil device opens the back, and the outside air can be followed from the air intake and sucked to air pipe in, and later, the air passes the heat exchanger fin and cools down or heat up the back, blows off from the mouth of blowing again, consequently, reaches and carries out even cooling or the purpose of heating up with plant room temperature.

However, the existing ventilation ducts have the following drawbacks:

1. ventilating duct is the pipeline of the rectangle barrel that adopts sheet metal to make generally, and the pipeline is generally fixed on the plant roof beam through the angle bar support, and this ventilating duct weight ratio is heavier, in case the installation is fixed, follow-up non-detachable.

2. The ventilating duct is only used for ventilation and almost does not need bearing strength, and the manufacturing and installation prices of the ventilating duct made of metal plates are not in direct proportion to the use purpose.

3. The air in the breeding house has high acidity and alkalinity and high humidity, and the metal plates of the ventilation pipelines need galvanized plates to prevent rusting and damage, so that the manufacturing and purchasing costs are greatly improved.

4. After the plant closes, old air pipe's dismantlement cost generally is greater than the cost of purchasing new air pipe, consequently, can't use after dismantling it once more, can't realize recycling, extravagant energy.

5. The most important defects are that because the environment of the farm is severe, dust is more, mosquitoes and flies are more, and secondly, in spring and autumn and other seasons which do not need refrigeration or heating, the windows of the farm are opened for a long time, so that the air volume in the farm is large, dust is more, and shutters of an air inlet and an air blowing opening of a ventilation pipeline are not tightly closed, and under the condition of long-time accumulation, too much dust, impurities and mosquitoes are easily accumulated in the ventilation pipeline; although the fan and the heat exchange plate can be cleaned every year or regularly, personnel cannot enter the ventilation pipeline and cannot clean dust, mosquitoes and impurities in the ventilation pipeline; meanwhile, the ventilating duct made of metal materials is heavy, so that dust cannot be cleaned after the ventilating duct is disassembled; and when opening the fan at every turn, air pipe air velocity is fast, can stir the stable dust in the pipeline again, blows off from the mouth of blowing again, leads to the indoor air dust concentration height that is in for a long time of plant, and the big condition of peculiar smell has increased the prevalence of livestock.
