Description

Technical Field

[0001] This utility model is specifically a combined factory roof exhaust device, which relates to the field of factory ventilation technology. Background Technology

[0002] There are two common ventilation methods used in workshops: natural ventilation and mechanical ventilation. Natural ventilation typically uses streamlined roof ventilators (see national standard diagram 06K105 for details). These ventilators are usually installed at the roof ridge and utilize thermal pressure to ventilate the interior of the building. The advantages of natural ventilation are large air volume, virtually no electricity consumption, and low risk of roof leaks. However, it is susceptible to changes in the indoor and outdoor environment, resulting in inconsistent ventilation performance. Mechanical ventilation, on the other hand, uses various types of roof fans and utilizes electricity to ventilate the interior of the building. The advantages of roof fans are relatively stable air volume, but they have disadvantages such as higher energy consumption and the presence of more openings in the roof, increasing the risk of leaks. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a combined factory roof exhaust device, which adopts the following technical solution: A modular factory roof exhaust system includes a streamlined roof natural ventilator installed on the foundation of a roof opening. Multiple modular exhaust units are arranged at the throat of the streamlined roof natural ventilator. Each modular exhaust unit consists of multiple fans and ventilation valves. The fans are used for mechanical exhaust, and the ventilation valves can be opened and closed for natural exhaust.

[0004] Further improve the technical solution: The ventilation valve plate is driven to open and close by an electric mechanism.

[0005] Further improvements to the technical solution include a grouping control circuit connected to each combined exhaust unit, which is used to control the opening and closing of each fan and ventilation valve.

[0006] Further improvements to the technical solution: Each combined exhaust unit is 3 meters long and consists of two fans and two oppositely arranged ventilation valve plates.

[0007] Further improvements to the technical solution: Each combined exhaust unit is 3 meters long and consists of multiple fans and four oppositely arranged ventilation valve plates.

[0008] Further improve the technical solution: install an inspection door at the throat of the streamlined roof natural ventilator.

[0009] After implementing the above technical solution, the beneficial effects of this utility model compared to the prior art are: This invention features multiple combined exhaust units arranged along the length of the throat of a streamlined roof natural ventilator. Each combined exhaust unit consists of multiple fans and ventilation valves. Normally, the ventilation valves can be partially or fully opened, utilizing natural wind or the thermal pressure between indoor and outdoor air for natural ventilation. When the ventilation volume cannot meet the factory's ventilation requirements, some or all ventilation valves can be closed while simultaneously turning on the fans to increase ventilation volume through mechanical exhaust.

[0010] This invention is unaffected by changes in indoor and outdoor environments and has the advantages of low energy consumption, low noise, and stable ventilation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] A modular factory roof exhaust system relates to the field of factory ventilation technology. The composition and working principle of this utility model are described in detail below.

[0016] See attached document Figure 1 and attached Figure 2 This utility model's combined factory roof ventilation device includes a streamlined roof natural ventilator 1 installed on the foundation 3 of the roof opening. The streamlined roof natural ventilator 1 is existing technology and can achieve natural ventilation by utilizing the thermal pressure of indoor and outdoor air. The advantages of the streamlined roof natural ventilator 1 are large exhaust volume, virtually no power consumption, and less likelihood of roof leakage; the disadvantages are that it is easily affected by changes in the indoor and outdoor environment, resulting in unstable ventilation performance.

[0017] To address the issue of unstable ventilation performance, multiple combined ventilation units 2 are arranged along the length of the throat of the streamlined roof natural ventilator 1. Each combined ventilation unit 2 consists of multiple fans 2.1 and ventilation valve plates 2.2. The fans 2.1 are used for mechanical ventilation, and the ventilation valve plates 2.2 can be opened and closed for natural ventilation.

[0018] In one embodiment, the width of the throat of the streamlined roof natural ventilator 1 is 2 meters, and the length of each combined exhaust unit 2 is 3 meters. The combined exhaust unit 2 consists of two fans 2.1 and two opposing ventilation valves 2.2. The ventilation valves 2.2 are 2×1m in size, and the fans 2.1 are 1×1m in size with a power of 1.1 kW. Each ventilation valve 2.2 is driven to open and close by a separate electric mechanism. Each combined exhaust unit 2 is connected to a group control circuit, which controls the opening and closing of each fan 2.1 and ventilation valve 2.2.

[0019] See attached document Figure 3 In another embodiment, the width of the throat of the streamlined roof natural ventilator 1 is 3 meters, and the length of each combined exhaust unit 2 is 3 meters. The combined exhaust unit 2 consists of three fans 2.1 and two oppositely arranged ventilation valve plates 2.2. The ventilation valve plates 2.2 are 2×1.5m in size, and the fans 2.1 are 1×1m in size and have a power of 1.1kw.

[0020] Normally, the group control circuit partially or fully opens the ventilation valve 2.2 as needed, utilizing natural wind or thermal pressure between indoor and outdoor air to achieve natural ventilation. When the ventilation volume cannot meet the factory's ventilation requirements, the group control circuit partially or fully closes the ventilation valve 2.2 as needed, while simultaneously starting the fan 2.1 for mechanical exhaust. The reason for closing the ventilation valve 2.2 is to create a relatively enclosed space at the throat of the streamlined roof natural ventilator 1, which facilitates the fan 2.1 in expelling more indoor air from the factory.

[0021] The fan 2.1 and ventilation valve plate 2.2 in the combined exhaust unit 2 can be arranged in various ways. For example, attached... Figure 4 The combined exhaust unit 2 consists of two fans 2.1 and four oppositely arranged ventilation valve plates 2.2, with attachments. Figure 5The combined exhaust unit 2 consists of three fans 2.1 and three ventilation valve plates 2.2 arranged in an alternating manner.

[0022] To facilitate maintenance of the fan 2.1 and ventilation valve plate 2.2, an inspection door (not shown in the figure) is provided at the throat of the streamlined roof natural ventilator 1.

[0023] In summary, this modular factory roof exhaust system is unaffected by changes in the indoor and outdoor environment and has the advantages of low energy consumption, low noise, and stable ventilation effect.

[0024] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
