Description

Technical Field

[0001] The utility model relates to the technical field of steel silos, in particular to a radial ventilation structure for steel silos. Background Art

[0002] A steel silo is a facility for storing powdery, granular or liquid materials, mainly made of steel plates. At present, steel silos are commonly used for storing paddy. The paddy will generate self-heat inside the steel silo, and the self-heat will cause the paddy to deteriorate inside the steel silo. Therefore, a ventilation structure is usually provided inside the steel silo for the paddy to dissipate heat and ventilate, so as to extend its storage time.

[0003] The existing ventilation structure inside the silo is to add ventilation pipes inside the silo, and then use a fan to send air into the silo to achieve the purpose of ventilation and heat dissipation. It has been disclosed in Chinese Patent Publication No. CN209594320U, Patent Name: Radial Ventilation System for Shallow Silos, that directly adding a central collecting air duct, an annular main air duct and a vertical branch air duct can evenly ventilate the entire grain pile, solving the problems of small air outlet area, large ventilation resistance value and poor cooling effect caused by the large diameter and high height of the shallow silo. However, this technical solution still has deficiencies in actual use. The central collecting air duct and the vertical branch air duct are vertically distributed inside the silo, and the air outlets of the two pipes are extremely easy to be blocked due to the pressure generated by the accumulation of grain, resulting in poor air outlet efficiency of the central collecting air duct and the vertical branch air duct, which is not conducive to continuous ventilation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a radial ventilation structure for steel silos to solve the above deficiencies in the technology.

Detailed implementation manners

[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] The present utility model provides a radial ventilation structure for a steel silo as shown in Figures 1-8 The figure, which includes a steel silo main body. The steel silo main body includes a silo 1. A funnel 3 is arranged at the bottom of the silo 1. A support frame 2 is arranged outside the funnel 3. A plurality of air ducts 41 are arranged on the inner wall of the funnel 3. A through hole 48 is formed in the outer wall of each air duct 41. An exhaust component 47 is inserted into the through hole 48. The exhaust component 47 includes a main elbow 471 arranged inside the air duct 41. The extended end of the main elbow 471 is connected with an auxiliary elbow 472. One end of the auxiliary elbow 472 is connected with an anti-blocking component 473. The anti-blocking component 473 is a hollow cone structure. A plurality of exhaust holes 4731 are formed at the top of the anti-blocking component 473. A connecting pipe 43 is arranged on one side of the air duct 41.

[0028] In this embodiment, specifically, after the air is conveyed by the ventilation mechanism 4, it enters the air duct 41 through the connecting pipe 43. The air pressure in the air duct 41 increases and enters from the main elbow 471. The air quickly passes through the main elbow 471 and enters the auxiliary elbow 472, and finally is discharged from the exhaust holes 4731 of the anti-blocking component 473. Because the number of the exhaust holes 4731 is large and the aperture is small, during the exhaust process, the paddy cannot enter the exhaust holes 4731 and will not block the exhaust holes 4731, so that the exhaust is smooth and stable. The air flows radially inside the silo 1, thereby dissipating heat and ventilating the paddy inside the silo 1.

[0029] As shown in Figures 1-4As shown, specifically, one end of the connecting pipe 43 is provided with a ventilation mechanism 4. The ventilation mechanism 4 includes a high-pressure blower 45. The air outlet of the high-pressure blower 45 is connected to a bent pipe, and the end of the bent pipe is connected to a U-shaped pipe 44. A one-way valve 42 is provided at the end of the U-shaped pipe 44, and the air outlet of the one-way valve 42 is connected to the connecting pipe 43. A waste discharge port is formed in the middle of the U-shaped pipe 44, and a plugging member 46 is inserted at the position of the waste discharge port.

[0030] In this embodiment, when the high-pressure blower 45 is started, the high-pressure blower 45 extracts air into the U-shaped pipe 44, and then passes through the one-way valve 42. The one-way valve 42 is a prior art and will not be elaborated here. The air enters the air duct 41 after passing through the connecting pipe 43. Specifically, the one-way valve 42 has the function of preventing backflow, avoiding impurities and dust from entering the U-shaped pipe 44 along with the air, and preventing impurities from being discharged from the high-pressure blower 45.

[0031] It should be noted that the plugging member 46 can be replaced with a pipe with a flange, and a valve needs to be installed on the pipe. By removing the plugging member 46 or opening the valve on the pipe, the impurities in the U-shaped pipe 44 can be discharged, avoiding the ventilation pipeline of the ventilation mechanism 4 from being blocked by impurities in the external air.

[0032] As Figure 2 and Figure 3 shown, support blocks 411 are provided at both ends of each air duct 41, and the ends of the support blocks 411 are in contact with the inner wall of the funnel 3. Specifically, holes are drilled from the outside of the funnel 3 between the support blocks 411 and the funnel 3, and they are connected by screwing bolts.

[0033] As Figures 2-3 shown, the air duct 41 is inclined on the inner wall of the funnel 3. The air duct 41 is a hollow cylindrical structure. A splicing seam is provided in the middle of the air duct 41, and both ends of the air duct 41 are sealed structures.

[0034] In this embodiment, after the external air enters the inside of the air duct 41 through the connecting pipe 43, the air fills the air duct 41, the air pressure inside the air duct 41 increases, and the air will not be discharged from both ends of the air duct 41. And during the installation of the exhaust component 47, the air duct 41 is divided into two hollow semi-cylindrical structures, and then the exhaust component 47 is assembled on the air duct 41.

[0035] As Figure 7 shown, a sealing ring 474 is provided between the auxiliary bent pipe 472 and the through hole 48.

[0036] In this embodiment, specifically, the sealing ring 474 is sleeved outside the secondary elbow 472. During the installation of the exhaust component 47, the main elbow 471 and the secondary elbow 472 are in an unconnected state. First, the secondary elbow 472 is passed through the through hole 48 from the outside of the air duct 41. At this time, the sealing ring 474 has been sleeved outside the secondary elbow 472. During the process of the secondary elbow 472 passing through the through hole 48, the sealing ring 474 is exactly clamped at the position of the through hole 48, and the gap between the through hole 48 and the secondary elbow 472 is filled and sealed by the sealing ring 474. The end of the exhaust component 47 and the end of the secondary elbow 472 are fixed by welding, so that the whole exhaust component 47 can be installed on the air duct 41. At this time, the installation of one exhaust component 47 has been completed, and the remaining exhaust components 47 can be assembled according to the same installation method to complete the installation.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different 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.
