Description

Technical Field

[0001] The utility model relates to the technical field of steel silos, in particular to a high-strength constant-temperature steel silo. Background Art

[0002] Steel silos are storage silos made of high-strength steel materials. Steel silos are large-scale storage facilities for storing bulk materials. At present, steel silos are widely used in agriculture, cement, coal, chemical and other industries. They have become an important storage facility for rice in agriculture.

[0003] Existing steel silos are generally placed directly outdoors. A large amount of rice can be stored inside a single steel silo. However, in low-temperature areas or low-temperature environments, the existing steel silos have poor thermal insulation functions and cannot be continuously stored at a constant temperature in a low-temperature environment. As a result, when the rice is at a temperature of zero degrees or below, the moisture in the rice may freeze, causing structural damage to the internal grains, thereby affecting the quality and germination rate of the rice.

[0009] Preferably, an opening is formed at one end of the ventilation plate close to the steel outer cylinder and contacts the inner wall of the heat insulation cover, and the opening communicates with the interior of the heat insulation cover.

[0010] Preferably, the outer wall of the ventilation plate is provided with a plurality of exhaust nozzles, each of the exhaust nozzles is inclinedly arranged on the outer wall of the ventilation plate, a main air hole is opened at the end of the exhaust nozzle, and a plurality of secondary air holes are opened on the outer wall of the exhaust nozzle.

The heat-insulating cover can block the contact between the rice inside and the structure outside it, which greatly improves the heat-insulating efficiency. In a low-temperature environment, the heat of the rice stored in the heat-insulating cover will not be conducted to the steel outer cylinder, which is beneficial to preserve the quality of the rice in a low-temperature environment and prolong the storage time of the rice.

[0016] 2. Through the ventilation assembly that is set up, the ventilation assembly is inserted into the interior of the heat insulation cover, the ventilation assembly is fixed on the top cover, and gas is input into the ventilation assembly through external high-pressure air supply equipment. The gas quickly enters the ventilation assembly and the interior of the heat insulation cover, and the air flows inside the heat insulation cover, which is beneficial to ventilate the air in the heat insulation cover. The gas is finally discharged from the bottom of the heat insulation cover. The ventilation process can continuously ventilate the rice stored in the heat insulation cover, thereby reducing the temperature in the heat insulation cover and avoiding the rice from heating up or rotting. This process does not require turning over the material, and the operation is simpler, saving manpower and material resources. In addition, the ventilation structure is adopted, the operation is safer, and the problem of generating a lot of dust can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The utility model provides Figure 1-Figure 7A high-strength constant-temperature steel silo shown in the figure comprises a steel outer cylinder 1, the inner wall of the steel outer cylinder 1 is provided with a heat-insulating assembly, the heat-insulating assembly comprises a first heat-insulating layer 101, the inner wall of the first heat-insulating layer 101 is fixed with a second heat-insulating layer 102, the inner wall of the second heat-insulating layer 102 is further provided with a heat-insulating cover 8, the heat-insulating cover 8 is a hollow structure, and the inner wall of the heat-insulating cover 8 is provided with a perforated plate 81, and the top and the top of the heat-insulating cover 8 are both opened; a top cover 3 is provided on the top of the steel outer cylinder 1, a feed pipe 4 is provided on the top of the top cover 3, a bottom support 12 is provided on the bottom of the heat-insulating cover 8, a bottom support bucket 9 is provided at the bottom of the bottom support 12, a discharge pipe 10 is fixed to the bottom of the support bucket 9, and the discharge pipe 10 is in a suspended state;

[0033] A plurality of exhaust holes 13 are provided at the top of the bottom bracket 12, and a fixing plate 11 is provided at the bottom of the bottom bracket 12. The outer wall of the fixing plate 11 is tightly fitted with the inner wall of the steel outer cylinder 1 and fixed by bolts.

[0034] In this embodiment, the rice is introduced from the top of the feed pipe 4 and the valve is opened. The rice passes through the feed pipe 4 and enters under the top cover 3. At the same time, the rice is also located in the inner space of the heat insulation cover 8 (not entering the hollow space inside the heat insulation cover 8). The rice also falls into the interior of the support bucket 9. As the rice is continuously added to the feed pipe 4, more and more rice is piled on the support bucket 9, and the rice eventually fills the inner space of the heat insulation cover 8. At this time, the heat insulation cover 8, the first insulation layer 101, the second insulation layer 102 and the steel outer cylinder 1 all protect the rice. The heat insulation cover 8, the first insulation layer 101, the second insulation layer 102 and the steel outer cylinder 1 have the function of heat preservation, which prevents the external temperature from being transmitted to the rice, and the temperature of the rice will not be transmitted to the steel outer cylinder 1, thereby maintaining the temperature of the rice.

[0035] like Figure 1-Figure 4 As shown, a steel plate layer 103 is further provided between the steel outer cylinder 1 and the second insulation layer 102;

[0036] Specifically, the steel plate layer 103 can strengthen the strength of the steel outer cylinder 1 , increase the pressure that the steel outer cylinder 1 can withstand, and increase the service life of the steel outer cylinder 1 .

[0037] like Figure 1 and Figure 2 As shown, the bottom of the steel outer cylinder 1 is a hollow structure, and a discharge vehicle entrance 2 is provided at the bottom of the steel outer cylinder 1;

[0038] It should be noted that the steel outer cylinder 1 is bulky. During the unloading process, the unloading truck can be driven into the interior of the steel outer cylinder 1 from the unloading truck entrance 2, and the truck bed of the unloading truck can be aligned with the bottom end of the discharge pipe 10. Valves are installed on the discharge pipe 10 and the feed pipe 4. The valve on the discharge pipe 10 can be opened to release the rice.

[0039] In another embodiment, if Figure 1-Figure 11As shown, specifically, a ventilation assembly is provided inside the heat insulation cover 8, and the ventilation assembly includes a ventilation plate 7, a ring tube 6 is provided at the top of the ventilation plate 7, a duct 51 is provided on one side wall of the ring tube 6, an air intake pipe 5 is provided on the top of the duct 51, and the ring tube 6 is located above the top cover 3. Specifically, the extended end of the air intake pipe 5 is connected to an external air supply device, and gas is continuously supplied through the air supply device. The air supply device can be replaced as needed to supply air of different temperatures, so as to adjust the temperature inside the heat insulation cover 8 to meet the needs of storing rice in the heat insulation cover 8. The optimal storage temperature of rice is between fifteen degrees Celsius and twenty degrees Celsius. The constant temperature inside the steel outer cylinder 1 is maintained by ventilation to preserve the rice, which can extend the storage time of the rice.

[0040] like Figure 2 and Fig.11 As shown, an opening is provided at one end of the ventilation plate 7 close to the steel outer cylinder 1 and contacts the inner wall of the heat insulation cover 8, the opening is communicated with the inside of the heat insulation cover 8, and a plurality of through holes are provided on the inner wall of the heat insulation cover 8; a plurality of exhaust nozzles 71 are provided on the outer wall of the ventilation plate 7, each exhaust nozzle 71 is inclinedly provided on the outer wall of the ventilation plate 7, a main air hole 711 is provided at the end of the exhaust nozzle 71, and a plurality of secondary air holes 712 are provided on the outer wall of the exhaust nozzle 71;

[0041] It should be noted that the air enters the annular tube 6 after passing through the air inlet pipe 5 and the duct 51. After the annular tube 6 is filled with air, the air enters the ventilation plate 7 under the action of air pressure. The contact portion of the ventilation plate 7 and the annular tube 6 is communicated, so that the air can enter the ventilation plate 7. After the ventilation plate 7 is filled with air, the air in the ventilation plate 7 is discharged from the end of the ventilation plate 7 and the exhaust nozzle 71 respectively because the air is continuously input into the ventilation plate 7. The gas discharged from the exhaust nozzle 71 enters the heat insulation cover 8 through the through hole on the inner wall of the heat insulation cover 8, and is finally discharged from the opening at the bottom of the heat insulation cover 8 and through the exhaust hole 13 of the bottom support 12, thereby discharging the air to the inside of the bottom end of the steel outer cylinder 1, and finally discharged from the inlet 2 of the unloading vehicle;

[0042] Specifically, an exhaust nozzle 71 is provided on the outer wall of the ventilation plate 7, and a plurality of auxiliary air holes 712 are opened on the outer wall of the exhaust nozzle 71. The auxiliary air holes 712 can blow air more evenly toward the interior of the heat insulation cover 8 in multiple directions, so that the air is in full contact with the rice in the heat insulation cover 8, which is conducive to quickly ventilating the rice and improving the ventilation efficiency, which can save ventilation time and improve the ventilation efficiency.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
