[0001] The utility model relates to the field of ventilation devices, in particular to a one-ventilation and three-protection ventilation device. Background Art

[0002] The one-way three-protection ventilation device is a high-efficiency ventilation device designed for improving air quality in harsh environments, ensuring fresh air in the workplace and protecting the health of employees. The one-way three-protection ventilation device can exhaust harmful gases and smoke, while blocking the entry of foreign pollutants, providing users with a safe and comfortable working environment;

[0003] The existing one-ventilation and three-protection ventilation devices have certain safety hazards during use, mainly because the fan part may generate high noise and vibration during operation, which affects the surrounding environment and equipment, and there is a risk of causing fire in environments such as mining. In addition, the installation and maintenance of the device are relatively inconvenient, requiring professional personnel to operate, which consumes time and manpower. These problems have limited the popularization and application of ventilation devices to a certain extent. Utility Model Content

[0004] The main purpose of the utility model is to provide a one-ventilation and three-protection ventilation device, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A one-way, three-protection ventilation device comprises a ventilation device base, an exhaust mechanism is provided on the top of the ventilation device base, the exhaust mechanism comprises an air duct, the front end of the air duct is fixedly connected to an outer shell, an inner plate is fixedly connected to the inner side of the outer shell near the rear, an air duct is fixedly connected to the rear of the outer shell, a water pipe is fixedly connected to the top of the air duct near the middle, a plurality of guide plates are fixedly connected to the inner side of the inner plate near the front, and one side of the guide plate is fixedly connected to the inner side of the outer shell near the front.

[0007] As a further solution of the utility model, a funnel is fixedly connected to the bottom of the air duct near the center, and a sewage pipe is fixedly connected to the bottom of the funnel.

[0008] As a further solution of the utility model, a circular hole is opened near the center of the bottom of the funnel, and the sewage pipe is L-shaped in shape.

[0009] As a further solution of the utility model, a plurality of air holes are evenly opened at the rear portion of the shell near the edge, and the outer shape of the shell is a cylinder with the front portion bent inward.

[0010] As a further solution of the present invention, the inner plate has a trumpet-shaped outer shape, and the larger opening of the inner plate faces rearward.

[0011] As a further solution of the utility model, the diameter of the middle part of the air duct is larger than the diameters of the two ends, and a plurality of water holes are evenly opened at a position close to the center of the top of the air duct.

[0012] As a further solution of the utility model, a plurality of guide plates are evenly distributed on the inner side of the inner plate near the front portion, and the guide plates are spiral in shape.

[0013] The beneficial effects of the utility model are as follows: by setting the exhaust mechanism, the one-way three-defense ventilation device can be operated without a fan, which improves the convenience of its installation and maintenance. At the same time, since the fan is removed, the noise of the device is reduced, and it is better integrated into various working environments. Especially in places with extremely high fire prevention requirements such as mining, the design of not using a fan helps to reduce fire risks, improves safety, and provides users with a quieter and safer working space;

[0014] By setting up water pipes, this design removes dust, bacteria and other harmful substances in the airflow through physical filtration to ensure air quality. The water in the water pipes has the function of moistening the airflow, which can reduce the dust concentration in the airflow, so that the ventilation device can ensure ventilation and dust prevention while also achieving environmental protection goals.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-3As shown, a one-way three-protection ventilation device includes a ventilation device base 1, an exhaust mechanism 2 is provided on the top of the ventilation device base 1, the exhaust mechanism 2 includes an air duct 3, the front end of the air duct 3 is fixedly connected to an outer shell 4, the inner side of the outer shell 4 is fixedly connected to an inner plate 5 near the rear, the rear part of the outer shell 4 is fixedly connected to an air pipe 6, the top of the air duct 3 is fixedly connected to a water pipe 7 near the middle, the inner side of the inner plate 5 is fixedly connected to a plurality of guide plates 8 near the front, and one side of the guide plate 8 is fixedly connected to the inner side of the outer shell 4 near the front.

[0021] In this embodiment, a funnel 9 is fixedly connected to a position near the center of the bottom of the air duct 3 , and a sewage pipe 10 is fixedly connected to the bottom of the funnel 9 .

[0022] The funnel 9 can collect the water sprayed from the water pipe 7 and discharge the water through the sewage pipe 10 at the bottom.

[0023] In this embodiment, a circular hole is opened at a position close to the center of the bottom of the funnel 9, and the sewage pipe 10 is L-shaped in appearance.

[0024] The water pipe 7 can spray water to wash the passing air and adhere to particles such as dust in the air.

[0025] In this embodiment, a plurality of air holes are evenly opened at the rear portion of the housing 4 near the edge, and the outer shape of the housing 4 is a cylinder with the front portion bent inward.

[0026] The air pipe 6 can deliver the air flow into the cavity formed by the outer shell 4 and the inner plate 5 through the air holes of the outer shell 4 .

[0027] In this embodiment, the inner plate 5 has a trumpet-shaped outer shape, and the larger opening of the inner plate 5 faces rearward.

[0028] An annular cavity can be formed between the inner plate 5 and the outer shell 4. When airflow enters the cavity, the pressure in the cavity increases.

[0029] In this embodiment, the diameter of the middle portion of the air duct 3 is larger than the diameters of the two ends, and a plurality of water holes are evenly opened at a position near the center of the top of the air duct 3 .

[0030] The shape of the air duct 3 can make the water flow sprayed from the water pipe 7 converge and enter the funnel 9 at the bottom and be discharged through the sewage pipe 10.

[0031] In this embodiment, a plurality of guide plates 8 are evenly distributed on the inner side of the inner plate 5 near the front, and the guide plates 8 are spiral in shape.

[0032] The guide plate 8 can guide the passing airflow so that the airflow is ejected at a certain inclination angle, thereby increasing the airflow speed.

[0033] It should be noted that the utility model is a one-way three-defense ventilation device. When in use, by connecting to the ground air source, the use of a fan is avoided, the fire risk and noise are reduced, and the ventilation device is easier to install, and at the same time, it can have a dust suppression effect;

[0034] The specific implementation method is to connect the top of the air pipe 6 to the compressed air from the ground, and the compressed air enters the cavity formed between the outer shell 4 and the inner plate 5 through the air pipe 6, and is blown out from the gap between the outer shell 4 and the inner plate 5 toward the direction of the air pipe 3. After the compressed air enters the cavity between the outer shell 4 and the inner plate 5, due to the small gap between the outer shell 4 and the inner plate 5, the compressed air cannot be blown out of the cavity between the outer shell 4 and the inner plate 5 at the first time, so the pressure in the cavity is increased. After the pressure in the cavity increases, the air flow speed passing through the gap between the outer shell 4 and the inner plate 5 will increase, and when the compressed air passes through the gap between the outer shell 4 and the inner plate 5, it will be guided by the guide plate 8 and sprayed out in an inclined state, further increasing the speed of the air flow;

[0035] The compressed air will be blown to the ground through the air duct 3. According to the Bernoulli principle, in the process of compressed air ejecting from the gap, the pressure at the location will be reduced due to the increase in speed. Therefore, the air in the front of the shell 4 will pass through the shell 4 and the inner side of the inner plate 5 under the action of the pressure difference, enter the air duct 3 and then be discharged to the outside. Since the ventilation device exhausts air through an external air source, it is not necessary to install a fan during installation, making the installation more convenient. In addition, since there is no need to set up a fan, the problem of fan overheating and sparks generated by friction is avoided, and maintenance is also more convenient, which can better adapt to operations in places where fire prevention is required, such as underground mining;

[0036] By connecting the water pipe 7 to a water source, water can be sprayed out from the inside of the air duct 3, thereby flushing the passing airflow, absorbing dust and impurities in the air, and preventing excessive dust from affecting the external environment. Water flows out from the position of the water pipe 7 at the top of the air duct 3 to form water droplets, and after absorbing dust and combining with other water droplets, the weight increases and then falls, gathering in the funnel 9, and finally discharged through the drain pipe 10, making the ventilation device more environmentally friendly.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
