Description

Technical Field

[0001] The utility model relates to the technical field of material storage, in particular to a vertical silo with rapid cooling. Background Art

[0002] The existing vertical silo is ventilated by natural wind for cooling, and its ventilation and cooling speed is slow. The lowest temperature is close to the outdoor temperature and changes with the outdoor temperature, and it cannot reach the optimal storage temperature of grains in real time.

[0003] The prior art 202322400136.9 discloses a new type of ventilation and air exchange structure for the silo top, which includes a conical silo top. Natural ventilation openings are arranged at intervals along the circumferential direction at the edge of the top surface of the silo top, and a group of induced draft fans are arranged at intervals along the circumferential direction at the center of the top of the silo top. In the above prior art, when the silo top needs ventilation and air exchange, the group of induced draft fans is started and operated to exhaust air to the outside of the silo top, which will form a negative pressure at the top of the inner silo of the silo top, causing the air in the silo top to flow towards the center of the top of the silo. The outside air enters the silo from the natural ventilation openings to fill the exhausted air, thereby realizing the rapid air exchange and cooling of the air in the silo top. The hot air between two adjacent natural ventilation openings will also naturally gather towards the top of the silo tip according to the principle of hot air rising, and is filled by the air entering from the natural ventilation openings, thereby effectively realizing the ventilation and cooling of the hot air. However, in the above prior art, only the silo top is used alone for ventilation and cooling, and the cooling speed still cannot meet the requirement of rapid cooling. Content of the Utility Model

An outlet is arranged at the bottom end of the steel cone. A diffuser pipe is arranged on the inner side surface of the steel cone. A cold air system connected to the diffuser pipe is arranged below the steel cone.

[0007] The utility model adopting the above technical solution, compared with the prior art, its prominent feature is:

[0008] A large amount of high-pressure cold air flows into the diffuser pipe through the cold air system and enters the internal materials at the bottom of the conical part of the silo, and then flows upward.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below in conjunction with embodiments, and the purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0018] A quick-cooling silo includes a silo barrel 1. The top of the silo barrel 1 is connected with a conical silo top 2. Natural ventilation openings 21 are arranged at intervals along the circumferential direction at the edge of the top surface of the silo top 1. Induced draft fan groups 22 are arranged at intervals along the circumferential direction at the center of the top of the silo top 1. The induced draft fan group 22 includes an induced draft elbow fixed on the silo top cap. A wind cap is arranged at the top of the induced draft elbow. A bracket is arranged between the induced draft elbow and the wind cap. An induced draft fan is arranged in the induced draft elbow. The bottom of the silo barrel 1 is connected with a steel cone 3. Support legs are arranged at the bottom of the silo barrel 1. A discharge port is arranged at the bottom end of the steel cone 3. An air dispersion pipe 4 is arranged on the inner side surface of the steel cone 3. A cold air system connected to the air dispersion pipe 4 is arranged below the steel cone 3.

[0019] Furthermore, the main body of the air dispersing pipe 4 is in the shape of a long strip arch. Sealing blocks are respectively arranged at both ends of the main body of the air dispersing pipe 4. The air dispersing pipe 4 is located above the discharge port and is radially buckled on the inner side surface of the steel cone 3. A bridge-shaped hole is formed in the air dispersing pipe 4.

[0020] Furthermore, the sealing block at the top end of the air dispersing pipe 4 is conical to prevent material jamming.

[0021] Furthermore, the cold air system includes a connected cold air blower 5 and a ventilator 6. An annular air collecting pipe 7 is arranged on the outer periphery of the steel cone 3. An air inlet elbow 8 communicating with the air dispersing pipe 4 is arranged on the air collecting pipe 7. An air inlet pipe 9 is arranged between the air outlet of the ventilator 6 and the air collecting pipe 7.

[0022] Furthermore, a temperature measuring cable 11 extending into the steel cone 3 is longitudinally arranged at the bottom of the silo top 2. A control cabinet 10 is arranged below the steel cone 3. The temperature measuring cable 11 is connected to the control cabinet 10. The control cabinet 10 is electrically connected to the cold air blower 5, the ventilator 6 and the induced draft fan group 22 respectively. A cold air chamber is arranged between the cold air blower 5 and the ventilator 6.

[0023] After the vertical silo is filled with materials, the internal temperature of the materials is detected through the temperature measuring cable 11. If the temperature is too high and not within the set range, the control cabinet 10 sequentially turns on the induced draft fan group 22, the ventilator 6 and the cold air blower 5. The cold air will pass through the cold air chamber to the ventilator 6, along the air inlet pipe 9 to the air collecting pipe 7, and is evenly distributed into the air dispersing pipe 4 through the air collecting pipe 7. The air dispersing pipe 4 injects the cold air into the interior of the steel cone 3 evenly and forcibly. The cold air rapidly rises in the voids of the materials. At the same time, the opening and reasonable arrangement of the silo top induced draft fan will quickly discharge the warm air (heat) of the materials at the top of the vertical silo. The natural ventilation opening 21 adjusts the pressure difference inside and outside the silo, and a uniformly and rapidly rising cold air flow will be formed inside the vertical silo to achieve the purpose of rapid cooling. Through the detection and feedback of the temperature measuring cable 11, when the temperature reaches the system set range, the equipment stops working; otherwise, the equipment continues to work.

[0024] A large amount of high-pressure cold air flows into the air dispersing pipe through the cold air system and enters the interior of the materials at the bottom of the silo cone, and then flows upward; a new type of silo top ventilation and air exchange structure is equipped at the top to ensure the smooth and efficient outflow of the warm air flow inside the vertical silo, achieving the rapid entry of cold air, the rapid outflow of the warm air flow to take away heat, and enabling the materials inside the vertical silo to reach the purpose of rapid cooling.

[0025] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of rights of the present invention accordingly. Any equivalent changes made by using the content of the specification and drawings of the present invention are included in the scope of rights of the present invention.
