Description

Technical Field

[0001] This utility model belongs to the technical field of grain storage equipment, and specifically relates to a grain storage tank. Background Technology

[0002] Grain plays an indispensable role in people's daily lives. Grain includes varieties such as wheat, beans, and rice. Different varieties can be processed into different types of food using different processing methods. After harvesting, some of the grain is sold as a commodity, while the rest is stored using storage devices, such as grain storage tanks.

[0003] When grain is put into storage, each batch of grain is inspected and tested according to requirements, and the test results are recorded. Grain that passes the inspection is weighed and recorded before being put into storage. Grain is classified according to different grades and varieties, and the classified grain is placed into grain storage tanks for storage.

[0004] For example, Chinese patent document with application number CN202321461590.9 discloses a grain storage tank, including a tank body, an inlet and an outlet on the tank body, a motor fixedly connected to the tank body, the output end of the motor extending into the tank body, a transmission rod connected to the extension end of the motor through a transmission component, a stirring component on the transmission component, and a fan fixedly connected to one end of the transmission rod.

[0005] However, rice is prone to sprouting and is not resistant to high temperatures, so special care is needed. When storing new rice, due to its vigorous respiration and high temperature and moisture content, ventilation should be strengthened and the grain surface should be deeply turned to dissipate the heat and moisture of the grain pile and prevent condensation. However, existing grain storage devices are not convenient for turning and ventilating the grain, which can easily lead to sprouting and mold. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A grain storage tank, comprising: The tank body has an internal air guiding structure; The frame, to which the tank is connected, provides support for the tank; An air supply device is provided on the side of the tank body. The front end of the air supply device is connected to a ventilation pipe that extends into the tank body, and the other end of the ventilation pipe is connected to the air guide structure. The air guiding structure includes a hollow tubular component that extends towards the height of the tank, and a number of air guiding holes are arranged along the outer periphery of the tubular component. At least one set of vent holes is provided on the outer wall of the tank along the axial direction, and a shielding part connected to the tank body is provided on the side of the vent hole.

[0007] Furthermore, the tubular component has several sets of protrusions on its peripheral wall, and the air guide hole is opened on the protrusions.

[0008] Furthermore, the tubular component is connected to the inner wall of the tank or coaxially via a support.

[0009] Furthermore, the shielding part is annular and is disposed on both sides of the exhaust port.

[0010] Furthermore, the shielding part is provided with an inclined surface.

[0011] Furthermore, a one-way valve is also provided at the vent, and the one-way valve is connected to the outer wall of the tank.

[0012] Furthermore, the bottom of the tank has a cone-shaped discharge hopper.

[0013] Furthermore, the top of the tank has a cover.

[0014] Compared with the prior art, this utility model has the following advantages: Fresh air blown in by an external air supply device is delivered into the tank through ventilation ducts. Because the tank is equipped with an air guide structure, the air is blown evenly into the tank through the air guide holes, thereby accelerating the gas flow inside the tank, speeding up the gas exchange between the inside and outside of the tank, improving ventilation efficiency, and reducing the temperature inside the grain silo, thus preventing the grain from deteriorating or turning sour due to high temperature.

[0018] like Figure 1 As shown, a grain storage tank of this utility model includes a tank body 1, a frame 4, and an air supply device 5. An air guide structure is connected inside the tank body 1; Tank 1 is connected to frame 4, which provides support for tank 1; The air supply device 5 is located on the side of the tank body 1. The front end of the air supply device 5 is connected to a ventilation pipe 6 that extends into the tank body 1. The other end of the ventilation pipe 6 is connected to the air guide structure. The air supply device 5 can specifically be a blower.

[0019] The air guiding structure includes a hollow tubular component 30 that extends towards the height of the tank 1, and a number of air guiding holes 32 are arranged along the outer periphery of the tubular component 30. Fresh air blown in by the external air supply device 5 is sent into the tank 1 through the ventilation pipe 6. Since the tank 1 is equipped with an air guide structure, the air is blown evenly into the inside of the tank 1 through the air guide hole 32, thereby accelerating the gas flow in the tank 1, accelerating the gas exchange inside and outside the tank 1, improving ventilation efficiency, and ventilation can reduce the temperature inside the grain silo and prevent the grain from deteriorating or turning sour due to high temperature. At least one set of vent holes 10 are provided on the outer wall of the tank body 1 along the axial direction, and a shielding part 2 connected to the tank body 1 is provided on the side of the vent hole 10.

[0020] Since the outer wall of the tank 1 is provided with a shielding part 2 located on the side of the exhaust port 10, it can prevent rainwater from the external environment from entering the tank 1 without affecting the exhaust.

[0021] Specifically, the tubular component 30 has several sets of protrusions 31 on its circumferential wall, and the air guide hole 32 is opened on the protrusions 31, which can reduce the blockage of the air guide hole 32 by the grain.

[0022] The tubular component 30 is connected to the inner wall of the tank 1 or coaxially via the support 33.

[0023] Specifically, the shielding part 2 is annular and is located on both sides of the exhaust port 10.

[0024] An inclined surface 20 is provided on the shielding part 2. With this design, the shielding part 2 is less prone to water accumulation.

[0025] In addition, a one-way valve (not shown in the diagram) is installed at the vent 10, which is connected to the outer wall of the tank 1. The one-way valve prevents small flying insects from entering through the vent 10 and causing the grain to spoil when the ventilation device 5 is not working. A filter screen can also be installed at the vent 10.

[0026] The tank body 1 has a cone-shaped discharge hopper 11 at the bottom. Correspondingly, the tank body 1 has a cover 12 at the top.

[0027] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
