Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, and specifically relates to a grain warehouse explosion relief and ventilation device. Background Technology

[0002] "Grain barn" is the most common and traditional form of grain storage building. As the name suggests, it is a single-story rectangular warehouse with a large span and volume. It is mainly used to store bulk grains (such as wheat, rice, corn, etc.). The ventilation system of the grain barn is the core system to ensure the safety of grain storage, while the explosion relief device is an important safety facility to deal with the risk of dust explosion. Although the two have different functions, they are both closely related to the gas state and safety inside the warehouse.

[0003] Existing explosion venting and ventilation devices for flat grain warehouses release heat upwards by installing explosion venting plates / windows on the most commonly used and effective roof, reducing safety hazards caused by heat buildup in the roof. Ventilation is achieved through ventilation openings on the side walls. However, during use, the explosion venting mechanism installed on the top of the grain warehouse occupies the roof space, which in turn affects the installation and use of grain conveying equipment and the grain storage process. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a grain storage explosion relief and ventilation device, which allows the air inside the grain storage to be quickly and stably discharged through the ventilation cavity, air outlet cavity and air outlet pipe. By setting an independent explosion relief vent in the air jacket at the top of the storage, it is completely separated from the grain storage ventilation. The design of the air jacket not only takes into account the storage of grain, but also takes into account the needs of grain storage ventilation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a grain storage venting and ventilation device, including a wall, a storage roof at the top of the wall, a ventilation cavity in the middle of the wall, an air outlet cavity in the middle of the storage roof, the air outlet cavity and the ventilation cavity being connected, an air outlet pipe on the upper surface of the storage roof, a top cover fixedly installed at the top of each air outlet pipe, symmetrically distributed baffles on the outer side of each air outlet pipe, multiple air outlets on the inner wall of the wall, each air outlet being connected to the ventilation cavity; four mounting plates fixedly installed inside each air outlet pipe, and an exhaust fan fixedly installed between each of the four adjacent mounting plates; multiple leakage holes on the lower surface of each baffle; symmetrically distributed door panels rotatably installed on the front side of the wall, each door panel having a handle on its front side.

[0006] As a further improvement of this utility model, a symmetrically distributed square frame is fixedly installed inside the ventilation cavity. Multiple air inlets are opened on the inner wall where the wall connects to the square frame. An air inlet pipe is installed on the outer wall where the wall connects to the square frame. An exhaust fan is installed inside the air inlet pipe.

[0007] As a further improvement of this utility model, a dustproof net is provided on the side of the air inlet pipe away from the ventilation cavity, and a dustproof net is detachably installed between the baffle and the air outlet pipe.

[0008] As a further improvement of this utility model, each air inlet is fixedly provided with a louver 1, and each air outlet is fixedly provided with a louver 2.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, under the action of the exhaust fan, the airflow entering the interior of the wall enters the ventilation cavity in the middle of the wall through the louvers set at the air outlet, and then enters the air outlet cavity in the middle of the warehouse roof through the ventilation cavity. Through the baffle, a positive and negative pressure difference is formed between the upper and lower sides of the same side of the air receiving surface, increasing the ventilation volume and wind speed, so that the air in the grain flat warehouse can be quickly and stably discharged through the ventilation cavity, air outlet cavity and air outlet pipe. By setting an independent explosion vent in the air jacket in the warehouse roof, it is completely isolated from the grain storage ventilation. The design of the air jacket not only considers the storage of grain, but also takes into account the needs of grain storage ventilation.

[0011] Secondly, an exhaust fan draws outside air between the square frame and the wall, and then the air enters the interior of the wall through louvers at the air inlet, thus ventilating the grain stored inside the wall. Attached Figure Description

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 3 , 4 As shown, the structure includes a wall 101, a top 102 at the top of the wall 101, a ventilation cavity 201 in the middle of the wall 101, an air outlet cavity 202 in the middle of the top 102, the air outlet cavity 202 being connected to the ventilation cavity 201, an air outlet pipe 203 on the upper surface of the top 102, a top cover 204 fixedly installed at the top of each air outlet pipe 203, symmetrically distributed baffles 205 on the outer side of each air outlet pipe 203, multiple air outlets 209 on the inner wall of the wall 101, each air outlet 209 being connected to the ventilation cavity 201; four mounting plates 207 fixedly installed inside each air outlet pipe 203, and an exhaust fan 208 fixedly installed between each of the four adjacent mounting plates 207; multiple drainage holes 211 on the lower surface of each baffle 205.

[0020] like Figure 2 As shown, a symmetrically distributed square frame 104 is fixedly installed inside the ventilation cavity 201. Multiple air inlets 105 are opened on the inner wall where the wall 101 connects to the square frame 104. An air inlet pipe 106 is installed on the outer wall where the wall 101 connects to the square frame 104. An induced draft fan 107 is installed inside the air inlet pipe 106.

[0021] like Figure 1 , 2 As shown, a dustproof net 108 is provided on the side of the air inlet duct 106 away from the ventilation cavity 201, and a dustproof net 206 can be detachably installed between the baffle 205 and the air outlet duct 203.

[0022] like Figure 2 , 4As shown, each air inlet 105 is fixedly equipped with a louver 109, and each air outlet 209 is fixedly equipped with a louver 210.

[0023] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, symmetrically distributed door panels 103 are rotatably mounted on the front side of the wall 101, and each door panel 103 has a handle on its front side.

[0024] In use, the induced draft fan 107 and the exhaust fan 208 are controlled to operate. The induced draft fan 107 introduces external air into the space between the square frame 104 and the wall 101, and then enters the interior of the wall 101 through the louver 109 set at the air inlet 105, thereby ventilating the grain stored inside the wall 101.

[0025] Airflow entering the interior of wall 101 enters the ventilation cavity 201 in the middle of wall 101 through louvers 210 at air outlet 209, and then enters the air outlet 202 in the middle of roof 102 through ventilation cavity 201. Under the action of exhaust fan 208, it enters the air outlet duct 203, and then through baffle 205, a positive and negative pressure difference is formed between the upper and lower sides of the same side of the air receiving surface, increasing the ventilation volume and wind speed. This allows the air in the grain warehouse to be quickly and stably discharged through ventilation cavity 201, air outlet 202 and air outlet duct 203. By setting an independent explosion vent in the air interlayer of roof 102, it is completely isolated from the grain storage ventilation. At the same time, the design of the air interlayer not only considers the storage of grain, but also takes into account the needs of grain storage ventilation.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
