Description

Technical Field

[0001] This utility model relates to the field of grain storage equipment, and in particular to a structure for reducing dust overflow from vertical silos. Background Technology

[0002] Vertical silos are a common type of grain storage equipment. They are cylindrical in shape, with the inlet and outlet located at the top and bottom of the cylinder. They offer advantages such as large capacity, small footprint, robust structure, and strong wind and earthquake resistance, making them suitable for storing various grains, oilseeds, and feed. However, due to their sealed nature, during the feeding process, the raw materials are drawn into the silo from the top. Factors such as the filling volume and the flow velocity created by the drop in height cause the air inside the silo to be compressed by the incoming material, forming a positive pressure airflow. This airflow releases dust from the silo through natural ventilation holes and vents, causing severe dust pollution and negatively impacting the on-site hygiene. Therefore, it is urgent to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a structure for reducing dust leakage from vertical silos. By connecting the natural ventilation openings of two vertical silos through a balancing duct, the positive pressure airflow generated during feeding is discharged into the other silo that is not receiving material, thereby dispersing and balancing the positive pressure airflow pressure inside the silo to suppress dust leakage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structure for reducing dust overflow from a vertical silo, comprising a first vertical silo and a second vertical silo, both of which are provided with natural air vents, and the natural air vents of the two vertical silos are connected by a balancing air duct.

[0005] Preferably, the balancing duct includes a right-angled duct interface connected to a natural air vent, and a connecting duct is located between the two duct interfaces.

[0006] Preferably, the inner diameter of the connecting pipe is 500 mm.

[0007] Preferably, the natural air vent is equipped with an air vent flange, and the pipe interface is connected to the air vent flange.

[0008] Preferably, the pipe interface is fixedly connected to an interface bracket, which can be detachably installed on the first or second vertical silo.

[0009] Preferably, the connecting pipe is inserted into the pipe interface for a sleeve fit, and the connecting pipe and the pipe interface can slide relative to each other.

[0010] Preferably, the pipe interface is fitted with a dust cover, the part of the dust cover that fits into the connecting pipe is tapered, and the tapered part has elastic deformation.

[0011] The technical effects of this utility model are as follows:

[0012] By connecting the natural ventilation openings of the two vertical silos through the balancing air duct, the positive pressure airflow generated during material feeding is discharged into the other silo that is not receiving material, thereby dispersing and balancing the positive pressure airflow pressure in the silo to suppress dust leakage.

[0013] The design of the interface bracket and air outlet flange, together with the sleeve fit of the pipe interface and connecting pipe, allows the bracket to be moved horizontally to close the natural ventilation opening when the air duct does not need to be balanced.

[0014] The dust cover design prevents dust from spilling from the pipe interface and the connection of the connecting pipe. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way. Example 1

[0020] like Figure 1-2 As shown, a structure for reducing dust overflow from a vertical silo includes a first vertical silo 1 and a second vertical silo 2. Both the first vertical silo 1 and the second vertical silo 2 are provided with natural air inlets 4. The natural air inlets 4 of the two vertical silos are connected by a balancing air duct 3. The balancing air duct 3 includes a right-angled pipe interface 5 connected to the natural air inlet 4. A connecting pipe 6 is located between the two pipe interfaces 5. The inner diameter of the connecting pipe 6 is 500 mm.

[0021] In the specific use of the structure in this embodiment, the first vertical silo 1 needs to be filled with bulk grain, while the second vertical silo 2 is empty. When the bulk grain enters the first vertical silo 1, the air pressure is released in the second vertical silo through the balancing air duct 3. The positive pressure airflow generated during feeding is then discharged into the other silo that has not been filled with grain through the air duct. This method of dispersing and balancing the positive pressure airflow in the silo achieves the purpose of suppressing dust leakage, thereby achieving the effect of balancing the air pressure in the feeding vertical silo. This solves the problem of dust escaping due to excessive positive pressure in the silo, providing a permanent solution, ensuring the cleanliness of the site environment, and effectively reducing the cost of sanitation and cleaning. Example 2

[0022] Compared to Embodiment 1, this embodiment adds the following structural limitations: the natural air vent 4 is fitted with an air vent flange 9, the pipe interface 5 is connected to the air vent flange 9, the pipe interface 5 is fixedly connected to an interface bracket 8, the interface bracket 8 is detachably installed on the first vertical silo 1 or the second vertical silo 2, the connecting pipe 6 is inserted into the pipe interface 5 for fitting, and the connecting pipe 6 and the pipe interface 5 can slide relative to each other, the pipe interface 5 is fitted with a dustproof sleeve 7, the part of the dustproof sleeve 7 that fits with the connecting pipe 6 is tapered, and the tapered part has elastic deformation.

[0023] Compared to Embodiment 1, in this embodiment, the pipe interface 5 achieves connection and separation from the natural air outlet 4 without moving the connecting pipe 6. Specifically, the interface bracket 8 is moved horizontally, thereby driving the pipe interface 5 to move horizontally along the connecting pipe 6. This allows the pipe interface 5 to be connected to and separated from the air outlet flange 9. During this process, the conical part of the dust cover 7 is always fitted onto the connecting pipe 6 and is in a state of being stretched and deformed, ensuring a good dustproof effect during the movement. After the connection or separation of the pipe interface 5 and the air outlet flange 9 is completed, the interface bracket 8 can be locked onto the vertical cylinder with bolts.
