Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a grain storage internal circulation temperature control and cooling device. Background Technology

[0002] Grain warehouses are places used to store grain. In hot weather, the temperature inside grain warehouses is high, so they need to be cooled down. Dry, cool air is generated by air conditioning and then introduced into the grain warehouse to cool it down.

[0003] Currently, the cold air generated by the air conditioner is introduced directly into the bottom of the grain silo through pipes laid at the bottom of the silo, and then spreads upwards from the bottom of the silo. However, the cold air is unevenly distributed during the transportation process, causing the cold air to flow chaotically within the grain silo, resulting in some areas of the grain silo not being cooled well. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a grain storage internal circulation temperature control and cooling device.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A grain storage silo internal circulation temperature control and cooling device includes a slow-flow box and a refrigeration air conditioner. The air outlet of the refrigeration air conditioner is connected to one side of the inside of the slow-flow box. The front end of the slow-flow box is connected to a bridge pipe at the middle. The bridge pipe is equipped with an air filter assembly. Three flow dividers are fixed at equal intervals between the inner walls of the two sides of the slow-flow box near the rear edge of the inside. The three flow dividers are located at the connection between the refrigeration air conditioner and the inside of the slow-flow box.

[0006] Optionally, a drive shaft is rotatably installed between the inner walls of the two sides of the flow chamber at the front edge, and multiple pressure-boosting blades are fixed at equal intervals along the circumferential direction on the outer surface of the drive shaft.

[0007] Optionally, one end of the drive shaft extends through to the outside of the buffer box, and a pulley is fixed to one end of the drive shaft.

[0008] Optionally, the front end of the bridge pipe is connected to two air inlet pipes, each of which is equipped with a control valve, and gaskets are fixed between the inner walls of the bridge pipe.

[0009] Optionally, a conical cover is slidably disposed between the inner walls of the bridge pipe, one end of the conical cover being closed, and one side of the conical cover being in contact with one side of the gasket ring.

[0010] Optionally, the conical shroud has multiple filter openings equidistantly on its conical surface along the circumferential direction. A fixed column is fixed to the inner bottom surface of the conical shroud, and a sliding sleeve is fitted onto the outer surface of the fixed column. Multiple vortex blades are fixed equidistantly along the circumferential direction on the outer surface of the sliding sleeve near the top edge.

[0011] Optionally, multiple scrapers are fixed at equal intervals along the circumferential direction on the outer surface of the sliding sleeve at the bottom edge, and the outer surfaces of the multiple scrapers are slidably attached to the inner wall of the conical cover.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time: 1. In this utility model, the cold air discharged from the refrigeration air conditioner is introduced into the slow flow box. Inside the slow flow box, the cold air is first divided by three diverting plates. Then, the pressure boosting blades driven by the drive shaft pressurize the divided cold air and deliver it to the bridge pipe. When the cold air flows inside the bridge pipe, it drives multiple vortex blades to drive the sliding sleeve to rotate, which in turn drives the scraper to scrape off the dirt filtered by the filter on the inner wall of the conical cover.

[0013] 2. In this utility model, the pressurized gas flows into the air inlet pipe through the bridge pipe. In actual use, the air inlet pipe is connected to the airflow pipe inside the grain silo, so that the pressurized cold air can be injected into the grain silo. The pressurized cold air can flow quickly inside the grain silo to the pipe laid at the bottom of the grain silo, which helps to diffuse evenly from the bottom of the grain silo upwards.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Example 1, such as Figure 1-4 As shown, this utility model provides a technical solution for a grain storage internal circulation temperature control and cooling device: it includes a slow flow box 1 and a refrigeration air conditioner 2. The air outlet of the refrigeration air conditioner 2 is connected to one side of the interior of the slow flow box 1. The front end of the slow flow box 1 is connected to a bridge pipe 3 at the middle. The bridge pipe 3 is equipped with an air filter assembly. Three diversion plates 6 are fixed at equal intervals between the inner walls of the two sides of the slow flow box 1 near the rear edge of the interior. The three diversion plates 6 are located at the connection between the refrigeration air conditioner 2 and the interior of the slow flow box 1.

[0019] The effect achieved by the entire embodiment 1 is that the cold air discharged from the air conditioner 2 is introduced into the slow flow box 1. Inside the slow flow box 1, the cold air is first divided by three diverter plates 6. Then, the pressure boosting blades 8 driven by the drive shaft 7 pressurize the divided cold air and deliver it to the bridge pipe 3. When the cold air flows inside the bridge pipe 3, it will drive multiple vortex blades 16 to drive the sliding sleeve 15 to rotate, which in turn drives the scraper 14 to scrape off the dirt filtered by the filter port 12 on the inner wall of the conical cover 11. The dirt after scraping will enter the bottom of the closed end of the conical cover 11 and accumulate for subsequent cleaning.

[0020] Example 2, as Figure 1-4 As shown, a drive shaft 7 is rotatably mounted between the inner walls of the two sides of the flow control box 1 at the front edge. Multiple pressure-boosting blades 8 are equidistantly fixed on the outer surface of the drive shaft 7 along the circumferential direction. One end of the drive shaft 7 extends to the outside of the flow control box 1, and a pulley 9 is fixed to one end of the drive shaft 7. The front end of the bridge pipe 3 is connected to two air inlet pipes 4, each equipped with a control valve 5. Gaskets 10 are fixed between the inner walls of the bridge pipe 3, and a conical shroud 11 is slidably mounted between the inner walls of the bridge pipe 3. One end of the conical shroud 11 is closed. One side of the cover 11 is in contact with one side of the gasket 10. The conical surface of the conical cover 11 has multiple filter ports 12 equidistantly arranged along the circumferential direction. A fixing post 13 is fixed on the inner bottom surface of the conical cover 11. A sliding sleeve 15 is fitted on the outer surface of the fixing post 13. Multiple vortex blades 16 are fixed equidistantly along the circumferential direction on the outer surface of the sliding sleeve 15 near the top edge. Multiple scrapers 14 are fixed equidistantly along the circumferential direction on the outer surface of the sliding sleeve 15 at the bottom edge. The outer surfaces of the multiple scrapers 14 are all slidably attached to the inner wall of the conical cover 11.

[0021] The effect achieved by the entire embodiment 2 is that the pressurized gas flows into the air inlet pipe 4 through the bridge pipe 3. In actual use, the air inlet pipe 4 is connected to the airflow pipe inside the grain silo, so that the pressurized cold air can be injected into the grain silo. The pressurized cold air can flow quickly inside the grain silo to the pipe laid at the bottom of the grain silo, which helps to diffuse evenly from the bottom of the grain silo upwards.

[0022] Working principle: The cold air discharged from the refrigeration air conditioner 2 is introduced into the slow flow box 1. Inside the slow flow box 1, the cold air is first divided by three diverter plates 6. Then, the transmission shaft 7 drives the pressure boosting blades 8 to pressurize the divided cold air and deliver it to the bridge pipe 3. When the cold air flows inside the bridge pipe 3, it drives multiple vortex blades 16 to drive the sliding sleeve 15 to rotate, which in turn drives the scraper 14 to scrape off the dirt filtered by the filter port 12 on the inner wall of the conical cover 11. The scraped dirt will accumulate at the bottom of the closed end of the conical cover 11 for easy cleaning later. The pressurized gas flows into the air inlet pipe 4 through the bridge pipe 3. In actual use, the air inlet pipe 4 is connected to the airflow pipe inside the grain silo, so that the pressurized cold air can be injected into the grain silo. The pressurized cold air can flow quickly inside the grain silo to the pipes laid at the bottom of the grain silo, which helps to diffuse evenly from the bottom of the grain silo upwards.
