Description

Technical Field

[0001] The utility model relates to the technical field of forced flow, in particular to a ventilation device for steel structure workshops. Background Art

[0002] A steel structure factory building mainly refers to a factory whose main load-bearing components are made of steel, including steel columns, steel beams, and steel foundations. Steel structure buildings are light in weight, high in strength, and have a large span. Steel structure buildings have a short construction period, are easy to move, and are pollution-free to recycle. In order to improve air quality and protect employee health, ventilation is required inside the factory building.

[0003] The ventilation device is based on the principle of natural ventilation. It uses the temperature and pressure difference between indoor and outdoor to achieve natural air flow, promote the exchange of indoor and outdoor air, and help maintain a comfortable and healthy working environment. During the air flow, dust and other particulate matter in the air will enter the factory. Especially when poplar fluff appears, these floating objects such as poplar fluff will fall on the ground and machines after entering the factory, which will have a serious impact on the working environment. At the same time, they will be inhaled by workers, which will affect the health of the respiratory system. Some of them will remain on the ventilation device, causing blockage and affecting ventilation efficiency. Utility Model Content

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the present invention provides a ventilation device for steel structure workshops, which has the following beneficial effects:

[0023] (1) The steel structure factory building uses a ventilation device. The outside air enters the interior of the second shell through the ventilation holes on the two ventilation baffles. At the same time, the pressure water pump inside the water tank works, and then pressurized water is sent to the interior of the water supply pipe. The water enters the interior of the water spray pipe through the water supply pipe, and then sprays downward through the water spray holes on the lower side of the water spray pipe. The water sprayed downward will form a water curtain, and then the water curtain will absorb floating debris such as poplar fluff in the air. Then, these water will fall into the interior of the water collection box through the connection port. At the same time, the water will be filtered through the filter plate, and then the floating debris will remain on the filter plate. The filtered water will flow to the interior of the water storage tank through the return pipe for recycling. In this way, the air entering the factory building through the ventilation fan can be filtered, and floating particles such as poplar fluff cannot enter the interior of the factory building, ensuring the working environment inside the factory building and the health of the workers, while also ensuring the ventilation efficiency of the ventilation device.

[0024] (2) The ventilation device for the steel structure factory building has ventilation holes on the two ventilation baffles that are staggered, so the wind force entering the second shell is weakened, thereby avoiding the situation where the water curtain is blown by strong wind and the water cannot fall into the filter plate. When the ventilation fan blows outward, the wind will first blow to the left side of the first shell and then enter the interior of the second shell, thereby avoiding the situation where the outward ventilation affects the water curtain. In this way, the interference of external factors on the impurity removal mechanism is avoided, and the stability of the impurity removal mechanism is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Furthermore, the water spray pipe 5 is fixedly connected to the upper side of the second shell 4, and the lower side of the water spray pipe 5 extends into the interior of the second shell 4. A plurality of water spray holes 6 are opened on the bottom wall of the water spray pipe 5, and the plurality of water spray holes 6 are arranged in a front-to-back manner. A water storage tank 7 is provided on the front side of the steel structure factory building body 1, and a pressurized water pump is provided inside the water storage tank 7. A water supply pipe 8 is fixedly connected to the front side of the water spray pipe 5, and the water supply pipe 8 is connected to the interior of the water spray pipe 5. The front end of the water supply pipe 8 extends into the interior of the water storage tank 7, and the front end of the water supply pipe 8 is connected to the pressurized water pump. The connecting port 9 is opened in the interior of the second shell 4, the upper side of the connecting port 9 extends into the interior of the second shell 4, and the lower side of the connecting port 9 extends out of the second shell 4.

[0033] Furthermore, the water collecting box 10 is fixedly connected to the lower side of the second shell 4, the water collecting box 10 is arranged at the position of the connecting port 9, the filter plate 11 is slidably connected to the inside of the water collecting box 10, and the front side of the filter plate 11 slides and extends out of the water collecting box 10. The front side of the filter plate 11 is fixedly connected with a handle 12, the return pipe 13 is fixedly connected to the lower side of the water collecting box 10, and the front end of the return pipe 13 extends into the interior of the water tank 7, and the two ventilation baffles 14 are fixedly connected to the inside of the second shell 4, the two ventilation baffles 14 are arranged on the left and right, and ventilation holes are opened on the two ventilation baffles 14, and the ventilation holes on the two ventilation baffles 14 are staggered.

[0034] When the machine starts working, when the outside air enters the interior of the steel structure factory building 1 through the ventilation fan 2, it will first enter the interior of the second shell 4 and pass through the ventilation holes on the two ventilation baffles 14. At the same time, the pressurized water pump inside the water tank 7 works, and then pressurized water is sent to the interior of the water supply pipe 8. The water enters the interior of the water spray pipe 5 through the water supply pipe 8, and then sprays downward through the water spray holes 6 on the lower side of the water spray pipe 5. The water sprayed downward will form a water curtain, and then the water curtain will absorb floating debris such as poplar fluff in the air, and then these water will fall into the interior of the water collecting box 10 through the connecting port 9.

[0035] At the same time, because the ventilation holes on the two ventilation baffles 14 are staggered, the wind force entering the second shell 4 will be weakened, thereby avoiding the situation where the water curtain is blown due to strong wind force, and the water cannot fall into the filter plate 11. When the ventilation fan 2 blows air outward, the blown wind will first blow to the left side of the first shell 3, and then enter the interior of the second shell 4, thereby avoiding the situation where outward ventilation affects the water curtain. In this way, the interference of external factors on the impurity removal mechanism is avoided, and the stability of the impurity removal mechanism is improved.

[0036] Working principle: When starting to work, when the outside air enters the interior of the steel structure factory building 1 through the ventilation fan 2, it will first enter the interior of the second shell 4, and pass through the ventilation holes on the two ventilation baffles 14. At the same time, the pressurized water pump inside the water tank 7 works, and then pressurized water is sent to the interior of the water pipe 8. The water enters the interior of the water spray pipe 5 through the water pipe 8, and then sprays downward through the water spray hole 6 on the lower side of the water spray pipe 5. The water sprayed downward will form a water curtain, and then the water curtain will absorb floating debris such as poplar catkins in the air, and then these water will fall into the interior of the water collecting box 10 through the connecting port 9. At the same time, the water will be filtered through the filter plate 11, and then the floating debris will remain on the filter plate 11. The filtered water will flow to the interior of the water storage tank 7 through the return pipe 13 for recycling.

[0037] At the same time, because the ventilation holes on the two ventilation baffles 14 are staggered, the wind force entering the second shell 4 will be weakened, thereby avoiding the situation where the water curtain is blown away by the strong wind, and the water cannot fall into the filter plate 11. When the ventilation fan 2 blows air outward, the blown wind will first blow to the left side of the first shell 3, and then enter the interior of the second shell 4, thereby avoiding the situation where outward ventilation affects the water curtain.
