Description

Technical Field

[0001] The utility model relates to the technical field of grain ventilation, in particular to a vertical silo storage ventilation system. Background Art

[0002] A silo is an upright container for storing grain. During storage, the grain needs to be ventilated to reduce the temperature and humidity inside the silo, thereby meeting the requirements for safe storage of the grain. Existing silo storage ventilation systems usually have an air duct at the center of the bottom of the silo body, and ventilation is achieved by blowing air upward through the air duct. However, this ventilation method is prone to ventilation dead corners, resulting in uneven ventilation of the grain in the circumferential direction of the silo and the grain in the center of the silo, which can easily cause the grain in the circumferential direction of the silo to mold and affect the storage quality. In addition, the grain is pressed against the air duct at the bottom of the silo under the action of its own gravity, which can easily block the air outlet of the air duct, thereby affecting the ventilation effect. Utility Model Content

To this end, the present invention provides a vertical silo storage ventilation system that can improve ventilation uniformity within the silo and reduce the likelihood of air outlet clogging, thereby improving ventilation quality.

[0004] According to an embodiment of the present utility model, a vertical silo storage ventilation system is provided, including a silo body and a ventilation mechanism, wherein a first air outlet is provided on the top of the silo body; the ventilation mechanism includes a fan, a first air duct and multiple second air ducts, the first air duct is vertically arranged at a central position inside the silo body, the second air duct is arranged at an adjacent position on the bottom wall inside the silo body, the second air duct is connected to the lower end of the first air duct, and multiple second air ducts are evenly arranged around the first air duct, the side wall of the first air duct is provided with multiple groups of first air outlet holes, and the multiple groups of first air outlet holes are arranged at intervals along the length direction of the first air duct, the side wall of the second air duct is provided with multiple groups of second air outlet holes, and the multiple groups of second air outlet holes are arranged at intervals along the length direction of the second air duct, and the output end of the fan is connected to the first air duct.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] It is understandable that, referring to Figures 1 to 5 The utility model of the vertical silo storage ventilation system includes a silo body 100 and a ventilator 210 structure 200. The top of the silo body 100 is provided with a first air outlet 110; the ventilator 210 structure 200 includes a fan 210, a first air duct 220 and a plurality of second air ducts 230. The first air duct 220 is vertically arranged at the center position inside the silo body 100, and the second air duct 230 is arranged at an adjacent position of the bottom wall of the silo body 100. The second air duct 230 and the first air duct 220 are connected. 0, a plurality of second air ducts 230 are evenly arranged around the first air duct 220, a plurality of first air outlet holes 221 are provided on the side wall of the first air duct 220, and the plurality of first air outlet holes 221 are arranged at intervals along the length direction of the first air duct 220, a plurality of second air outlet holes 231 are provided on the side wall of the second air duct 230, and the plurality of second air outlet holes 231 are arranged at intervals along the length direction of the second air duct 230, and the output end of the fan 210 is connected to the first air duct 220.

[0030] The grain is stored inside the silo 100, and air is transported to the first air duct 220 and the second air duct 230 through the fan 210. The air flows from the first air duct 220 from bottom to top. Since the multiple groups of first air outlet holes 221 are arranged at intervals along the length direction of the first air duct 220, the air flows out from the multiple groups of first air outlet holes 221 arranged at intervals and diffuses to the surrounding grain layer. When the air flows through the grain layer, it takes away the heat and moisture of the grain and is discharged from the first air outlet 110 on the top of the silo 100. Since the first air duct 220 is arranged vertically and the first air outlet holes 221 are arranged at intervals along the length direction of the first air duct 220, the air flows out from the multiple groups of first air outlet holes 221 arranged at intervals and diffuses to the surrounding grain layer. When the air flows through the grain layer, the air takes away the heat and moisture of the grain and is discharged from the first air outlet 110 on the top of the silo 100. 221 is arranged on the side wall of the first air duct 220, so that the grain is horizontally pressed against the side wall of the first air duct 220, which can reduce the possibility of the first air outlet 221 being blocked, thereby improving the ventilation quality. At the same time, since the multiple second air ducts 230 are evenly arranged around the first air duct 220, the air flows toward the periphery along the multiple second air ducts 230, and flows out from the multiple groups of second air outlet holes 231 arranged at intervals, and then is transported upward to the first air outlet 110 for discharge, which can ventilate the grain in the circumferential direction, thereby improving the ventilation uniformity and ventilation quality.

[0031] It should be noted that the upper end of the first air duct 220 is sealed, and the end of the second air duct 230 away from the first air duct 220 is sealed, so that air flows out from the first air outlet 221 or the second air outlet 231 .

[0032] The apertures of the first air outlet 221 and the second air outlet 231 are smaller than the particle size of the grain, thereby reducing the possibility of the grain entering the first air duct through the first air outlet 221 or entering the second air duct through the second air outlet 231 .

[0033] A top cover 150 can be provided on the top cover of the silo body 100, and the first air outlet 110 is provided on the top cover 150, so that the top cover 150 can be conveniently opened to input food into the silo body 100. The top surface of the top cover 150 can be provided as a raised cone, which can facilitate water diversion and drainage, and reduce the possibility of water leakage into the silo body 100 due to water accumulation on the top.

[0034] The inner bottom wall of the silo body 100 can be set to a downwardly protruding cone, and a discharge port 160 is opened on the inner bottom wall of the silo body 100 to facilitate the diversion and unloading of grain.

[0035] It is understandable that, referring to Figure 1 and Figure 2 The multiple groups of first air outlet holes 221 are evenly spaced along the length of the first air duct 220. By arranging the multiple groups of first air outlet holes 221 at equal intervals along the length of the first air duct 220, air is evenly blown out from the multiple first air outlet holes 221 evenly spaced in the vertical direction to the surrounding area, thereby improving the uniformity of ventilation of the grain in the vertical direction of the silo 100.

[0036] Specifically, refer to Figure 1 and Figure 2 The multiple first air outlet holes 221 in each group are evenly spaced along the circumference of the first air duct 220. By evenly arranging the multiple first air outlet holes 221 in each group along the circumference of the first air duct 220, air is evenly blown out from the multiple first air outlet holes 221 on the same horizontal plane to the surrounding area, thereby improving the uniformity of ventilation of the grain in the circumferential direction of the silo 100.

[0037] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 5 The multiple groups of second air outlet holes 231 are arranged at equal intervals along the length of the second air duct 230. By arranging the multiple groups of second air outlet holes 231 at equal intervals along the length of the second air duct 230, air can be evenly blown out from the multiple groups of second air outlet holes 231 at equal intervals, thereby improving the uniformity of ventilation of the grain in the radial direction of the silo 100.

[0038] It is understandable that, referring to Figure 3 and Figure 5 The outer walls of the first and second air ducts 220, 230 are each provided with a plurality of spherical protrusions 240. Each spherical protrusion 240 corresponds to either a first air outlet 221 or a second air outlet 231. Both the first and second air outlets 221, 231 are formed on the spherical protrusions 240. Since both the first and second air outlets 221, 231 are formed on the spherical protrusions 240, the spherical surfaces of the spherical protrusions 240 guide the grain to adhere obliquely to the spherical surfaces, reducing the possibility of grain clinging parallel to the outer walls of the first and second air ducts 220, 230 and blocking the first and second air outlets 221, 231, thereby improving ventilation quality. Furthermore, the spherical surfaces of the spherical protrusions 240 reduce damage to the grain when it slides along the outer walls of the first and second air ducts 220, 230, thereby improving grain storage quality.

[0039] It is understandable that, referring to Figures 1 to 4The fan structure 210 200 also includes a first bellows 250, a second bellows 260 and a driving member 270. The second bellows 260 is fixedly arranged at the bottom of the warehouse body 100. The output end of the fan 210 is connected to the second bellows 260. The first bellows 250 is rotatably connected to the second bellows 260, and the first bellows 250 is connected to the second bellows 260. The first air duct 220 and the second air duct 230 are both connected to the first bellows 250, and the first air duct 220 and the second air duct 230 are both connected to the first bellows 250. The driving member 270 is used to drive the first bellows 250 to rotate. Since the output end of the fan 210 is connected to the second wind box 260, the first wind box 250 is connected to the second wind box 260, and the first air duct 220 and the second air duct 230 are both connected to the first wind box 250, air is transported to the first wind box 250 by the fan 210, and the air flows from the first wind box 250 into the second wind box 260, and is diverted to the first air duct 220 and the second air duct 230 through the second wind box 260, thereby achieving ventilation. Since the first wind box 250 is rotatably connected to the second wind box 260, and the first air duct 220 and the second air duct 230 are both connected to the first wind box 250, the first wind box 250 is driven to rotate by the driving member 270, thereby driving the first air duct 220 and the second air duct 230 to rotate around the axial direction of the first air duct 220, which can stir the grain and make the grain slide along the side walls of the first air duct 220 and the second air duct 230, thereby reducing the possibility of grain blocking the first air outlet 221 and the second air outlet 231, thereby improving the ventilation quality. In addition, stirring can reduce the possibility of grain arching.

[0040] It should be noted that the driving member 270 can be a motor, a cylinder, an oil cylinder, etc., as long as it can drive the first bellows 250 to rotate.

[0041] Through holes are provided on the side walls of the connection between the first bellows 250 and the second bellows 260 , and the first bellows 250 and the second bellows 260 are connected through the through holes.

[0042] Specifically, refer to Figure 1Along the axial direction of the silo 100, an air inlet 120 is defined on the central inner sidewall of the silo 100. An air outlet 130 is defined on the sidewall of the silo 100, with the air inlet 120 communicating with the air outlet 130. A second air outlet 140 is defined on the top outer sidewall of the silo 100, with the second air outlet 140 communicating with the air outlet 130. As air flows upward within the silo 100, it gradually removes heat and moisture from the lower grain layers until it reaches saturation. Saturated air is unable to absorb heat and moisture from the upper grain layers and may cause secondary contamination to the cooled and dehumidified grain layers. The air inlet 120 defined on the central inner sidewall of the silo 100 allows upward air flow from the central air inlet 120 into the air outlet 130 and out through the second air outlet 140 along the air outlet 130. This reduces the possibility of secondary contamination of the upper grain layers, thereby improving the efficiency of grain cooling and dehumidification.

[0043] It should be noted that the diameter of the air inlet 120 is smaller than the particle size of the grain, which can reduce the possibility of the grain entering the air outlet channel 130 through the air inlet 120.

[0044] Specifically, refer to Figure 1 A scraper 222 is fixedly mounted on the outer wall of the first air duct 220. The scraper 222 abuts the inner wall of the silo 100 and is located at the same height as the air inlet 120 in the axial direction of the silo 100. The first air duct 220 is rotated by the driving member 270, which drives the scraper 222 to rotate about the axial direction of the first air duct 220. Since the scraper 222 abuts the inner wall of the silo 100 and is located at the same height as the air inlet 120 in the axial direction of the silo 100, the scraper 222 can scrape the grain near the air inlet 120 when it rotates, promoting grain flow, thereby reducing the possibility of grain blocking the air inlet 120 and improving ventilation quality.

[0045] It should be noted that the scraper 222 can be provided in plurality, and the plurality of scrapers 222 are evenly arranged at intervals along the circumference of the first air duct 220 , which can improve the scraping efficiency and further reduce the possibility of grain blocking the air inlet 120 .

[0046] Specifically, refer to Figure 1 A plurality of air inlets 120 are provided, and the plurality of air inlets 120 are evenly spaced along the circumference of the silo body 100. Air can enter the air outlet channel 130 through the plurality of air inlets 120 evenly spaced along the circumference of the silo body 100, thereby accelerating the exhaust efficiency of the air and improving the ventilation efficiency.

[0047] Specifically, refer to Figure 1The second air outlet 140 is provided with a plurality of second air outlets 140, which are evenly spaced along the circumference of the silo body 100. Air can be discharged from the plurality of second air outlets 140 evenly spaced along the circumference of the silo body 100, thereby accelerating the exhaust efficiency of the air and improving the ventilation efficiency.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
