Description

Technical Field

[0001] This utility model relates to the field of factory ventilation structure technology, specifically a factory building ventilation and air exchange structure. Background Technology

[0002] Factory ventilation is a systematic engineering project that replaces indoor and outdoor air through mechanical or natural means. Its core function is to remove heat from the factory and introduce fresh air, ensuring the health of personnel and the normal operation of equipment. Common forms are natural ventilation and mechanical ventilation. Natural ventilation uses doors, windows and skylights to create air convection, while mechanical ventilation uses fans to force air exchange. One wall of the factory is equipped with a fan that draws air inward and another wall is equipped with a fan that exhausts air outward, so that the air inside the factory is convective, which is conducive to removing heat and introducing fresh air.

[0003] In summer, when outdoor temperatures are high, the air blown into the factory is also relatively hot. This means that although fresh air is introduced, it cannot be used to cool the interior, making it difficult to lower the temperature inside the factory. Therefore, we propose a ventilation and air exchange structure for factory buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation structure for factory buildings. By installing multiple longitudinally distributed cotton ropes on the side of a waterproof fan inside the air inlet pipe, with the bottom of the cotton ropes extending into a fixed water tank below, sufficient water can be moistened into the cotton ropes through capillary action. During ventilation, the airflow causes the water in the cotton ropes to evaporate, thereby absorbing heat and lowering the temperature of the air blown into the factory building, which is beneficial for cooling the factory building and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation structure for factory buildings, including an air inlet pipe and a vertical pipe. The vertical pipe is integrally connected to the side of the air inlet pipe, and the opening of the vertical pipe faces directly downward. A waterproof fan blowing air outward is vertically installed inside the air inlet pipe near the outer side. A longitudinally distributed water trough is fixed below the air inlet pipe on the side of the waterproof fan. Multiple cotton ropes are vertically arranged inside the air inlet pipe on the side of the waterproof fan in the longitudinal direction. The upper part of the cotton rope is embedded in a sleeve welded and fixed to the upper surface of the air inlet pipe, and the lower part of the cotton rope passes through a through-hole opened on the surface of the air inlet pipe and extends into the water trough and into the lower part of the water trough.

[0006] By adopting the above technical solution, when the waterproof fan starts working, its airflow will pass between multiple longitudinally distributed cotton ropes. Due to capillary action, the cotton ropes will be moistened with water from the water tank. The airflow can increase the evaporation rate of the water in the cotton ropes, thereby absorbing the heat of the air. When blown into the factory, it is beneficial to cool the interior of the factory.

[0007] Optionally, an outer baffle is fixed horizontally inside the lower part of the vertical pipe to prevent external impurities from entering the vertical pipe.

[0008] Optionally, an inner baffle is vertically fixed inside the end of the air intake pipe on the side of the waterproof fan to prevent impurities in the factory from entering the air intake pipe.

[0009] Optionally, reinforcing rods are welded and fixed inside the air intake pipe, the vertical pipe, and the connection between the air intake pipe and the vertical pipe, and multiple reinforcing rods are provided.

[0010] By adopting the above technical solution, the large inner diameter of the intake pipe and the vertical pipe can achieve the purpose of increasing the overall strength of the intake pipe and the vertical pipe.

[0011] Optionally, a float valve is installed on the upper side wall surface inside the water tank, with the inlet of the float valve extending to the outside of the water tank.

[0012] By adopting the above technical solution, the float valve is used to automatically replenish water into the water tank.

[0013] Optionally, a lifting ring is fixed at the upper middle position of the air intake pipe, and the bottom of the lifting ring is connected to the upper part of the air intake pipe by welding.

[0014] By adopting the above technical solution, the entire device can be lifted using lifting rings during installation, thus facilitating its installation.

[0015] Optionally, a mounting plate is welded and fixed to the outer ring of the air intake pipe on the side of the waterproof fan, and multiple perforations are evenly opened on the surface of the mounting plate.

[0016] By adopting the above technical solution, when the right end of the air intake pipe is aligned with the air inlet of its factory, the bolt passes through the through hole in the mounting plate, thereby achieving the installation and fixation of the mounting plate and the device.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application has multiple longitudinally distributed cotton ropes installed on the side of the waterproof fan inside the air intake pipe. The bottom of the cotton ropes extends into the water tank fixed below. Capillary action can be used to wet a sufficient amount of clean water into the cotton ropes. During ventilation, the airflow is used to evaporate the water in the cotton ropes, thereby absorbing heat and cooling down, thus reducing the temperature of the air blown into the factory building, which is beneficial for cooling the factory building.

[0019] 2. The technical solution of this application sets the opening of the vertical pipe downwards, which can prevent rainwater from entering when the vertical pipe is placed outdoors. Furthermore, baffles are installed at the ends of the air inlet pipe and the vertical pipe to prevent impurities from entering the air inlet pipe or the vertical pipe. Attached Figure Description

[0024] Please see Figure 1-2 This utility model provides a technical solution: a ventilation structure for a factory building, including an air inlet pipe 1 and a vertical pipe 2. The vertical pipe 2 is integrally connected to the side of the air inlet pipe 1, and the opening of the vertical pipe 2 faces directly downward. An installation plate 11 is welded and fixed to the outer ring of the right end of the air inlet pipe 1. Multiple through holes 111 are evenly opened on the surface of the installation plate 11. During installation and use, the right side of the air inlet pipe 1 is aligned with the air inlet of the factory building, and the installation plate 11 is in contact with the outer surface of the factory building. Then, bolts can be passed through the through holes 111 and through the installation plate 11 to install and fix the installation plate 11 and the air inlet pipe 1.

[0025] Because the device is relatively large and inconvenient to install, a lifting ring 12 is fixed at the middle position above the air intake pipe 1. The bottom of the lifting ring 12 is connected to the upper part of the air intake pipe 1 by welding. During installation, the device can be lifted by lifting equipment using a lifting rope, which facilitates movement and installation.

[0026] A waterproof fan 13 is vertically installed inside the air intake pipe 1, near the mounting plate 11. The waterproof fan 13 blows air outward to the right side of the air intake pipe 1. The motor and transmission structure of the waterproof fan 13 are waterproofed and can work stably in high humidity environments. When in use, the waterproof fan 13 starts and blows air into the factory building on the right side, allowing outside air to enter the factory building. The air inside the factory building can be naturally discharged from the air outlet on the other side, or drawn out by the exhaust fan installed at the ventilation opening on the other side.

[0027] An inner baffle 14 is vertically fixed inside the end of the air intake pipe 1 on the right side of the waterproof fan 13, which can be used to block impurities in the factory from entering the air intake pipe 1. In addition, an outer baffle 21 is horizontally fixed inside the lower part of the vertical pipe 2, which can be used to block external impurities from entering the vertical pipe 2.

[0028] Because the inner diameters of the intake pipe 1 and the vertical pipe 2 are relatively large, in order to increase the strength of the intake pipe 1 and the vertical pipe 2, reinforcing rods 5 are welded and fixed inside the intake pipe 1, the vertical pipe 2, and the connection between the intake pipe 1 and the vertical pipe 2.

[0029] In actual use, the machines inside the factory generate even more heat, leading to excessively high temperatures inside the factory. Therefore, the ventilation system is designed to introduce outside air not only to bring in fresh air but also to cool the factory interior. However, in summer, the outside air temperature is also relatively high, resulting in high-temperature incoming air and insufficient cooling effect on the factory interior. To solve this problem:

[0030] This application provides a water tank 3 with a longitudinal distribution fixed below the air intake pipe 1 on the side of the waterproof fan 13. The water tank 3 is used to store clean water. Inside the air intake pipe 1 on the left side of the waterproof fan 13, multiple cotton ropes 4 are vertically arranged in the longitudinal direction. A sleeve 15 is welded and fixed to the bottom surface of the air intake pipe 1 directly above each cotton rope 4, so that the upper part of the cotton rope 4 is embedded in the upper sleeve 15, thereby fixing the upper part of the cotton rope 4. The surface of the air intake pipe 1 below the cotton rope 4 has a through-hole 31 that communicates with the inside of the water tank 3, so that the lower part of the cotton rope 4 passes through the through-hole 31 into the water tank 3 and extends to the lower part of the water tank 3. The outer part of the cotton rope 4 is close to the inner surface of the through-hole 31. When there is enough clean water in the water tank 3, the cotton rope 4 will be wetted upward due to capillary action. When the waterproof fan 13 is started, the airflow flowing to the right passes between the cotton ropes 4, causing the water to evaporate quickly and absorb heat, thereby reducing the temperature of the incoming air and helping to cool the interior of the factory.

[0031] A float valve 32 is installed on the upper side wall surface inside the water tank 3. The inlet of the float valve 32 extends to the outside of the water tank 3. When in use, the float valve 32 is connected to the clean water supply pipe, which can automatically replenish clean water to the specified water level when the water tank 3 is short of water, without the need for manual water replenishment.

[0032] In use, the mounting plate 11 on the right side of the air inlet pipe 1 is placed against the surface of the air inlet of the factory building. The bolts are then passed through the through holes 111 to install and fix the mounting plate 11 and the air inlet pipe 1. The right side of the air inlet pipe 1 is aligned with the air inlet of the factory building. The vertical pipe 2 is located outside the factory building. An exhaust fan can be installed at the air outlet on the other side of the factory building as needed, or it can be left open. Connect the clean water supply pipe to the inlet of the float valve 32, and connect the waterproof fan 13 to the power supply and start it to blow air into the factory. The clean water will automatically replenish the water tank 3 to a fixed level through the float valve 32. When the water level drops, the float valve 32 can be used to automatically replenish water again. Due to capillary action, the clean water will rise and completely wet the cotton rope 4. When the outside air enters from below the vertical pipe 2 and passes through the multiple cotton ropes 4 distributed in the longitudinal direction, the water evaporates due to the airflow and absorbs heat. This can effectively reduce the temperature of the air blown into the factory by the waterproof fan 13, thereby facilitating ventilation and cooling of the factory. The hot air is discharged from the air outlet on the other side by the exhaust fan or directly discharged.
