Description

Technical Field

[0001] The invention belongs to the technical field of grain storage granaries, and in particular relates to a granary with a cooling pipe. Background Art

[0002] In recent years, with the continuous progress and development of society, the output of grain has been increasing, the amount of grain stored by farmers has been increasing, and the requirements for granaries have become higher and higher. In order to ensure the storage quality of grain in the granary, it is necessary to control the air flow and temperature in the granary. Since the granary is a closed space, the heat cannot be dissipated under the sunlight, which will increase the temperature of the warehouse. When the temperature is too high, the grain will become moldy and there will be safety hazards. If the air flow in the granary is not good, it will also cause uneven temperature in the granary, and the temperature in some areas will be too high, affecting the quality of the grain. At present, the existing method of cooling the granary mainly includes arranging air conditioners in the granary. This method can only cool the air on the surface of the grain and above the surface of the grain, and cannot cool the grain at the bottom of the granary. In addition, the position of the air conditioner is fixed, and it cannot be cooled by area according to demand, and it cannot achieve precise cooling. At the same time, the granary also needs a circulation device to ensure air circulation in the granary. At present, the cooling system and the circulation device in the existing granary are mostly arranged separately, and the individual control operation is complicated, and the structure is complex, the space occupied is large, and the cost is high. Summary of the invention

[0003] In order to solve the above-mentioned shortcomings of the complex structure of the existing granary cooling and circulation devices, the present invention provides a granary with a cooling pipe.

[0004] The technical solution of the present invention:

[0005] A granary with a coolable pipe comprises a granary body and a coolable pipe system, wherein the coolable pipe system is composed of at least two layers of cooling pipe sets, wherein the upper and lower ends of the coolable pipe system are respectively connected to the side walls of the granary body and are communicated with the interior of the granary body, and valves are arranged at the gaps between the two ends of the two adjacent layers of cooling pipes.

[0006] Preferably, the coolable pipe system is two-layered, comprising an outer pipe and a first inner pipe, the upper and lower ends of the outer pipe are respectively connected to the side walls of the granary body and communicated with the interior of the granary body, the upper and lower ends of the first inner pipe are respectively connected to the side walls of the granary body, the upper end of the first inner pipe is communicated with the interior of the granary body, and the lower end does not extend into the side wall of the granary body, and the first valve and the second valve are respectively arranged at the gap between the outer pipe and the two ends of the first inner pipe.

[0007] Preferably, the coolable pipe system is three-layered, comprising an outer pipe, a first inner pipe and a second inner pipe, the upper and lower ends of the outer pipe are respectively connected to the side walls of the granary body and communicated with the interior of the granary body, the upper and lower ends of the first inner pipe and the second inner pipe are respectively connected to the side walls of the granary body, the upper ends thereof are communicated with the interior of the granary body, and the lower ends do not extend into the side walls of the granary body, the first valve and the second valve are respectively arranged at the gap between the outer pipe and the first inner pipe, and the third valve and the fourth valve are respectively arranged at the gap between the first inner pipe and the second inner pipe.

[0008] Preferably, a vacuum pump interface is arranged on the outer wall of the outermost cooling tube.

[0009] Preferably, a ventilation door is arranged on the outer wall of the lower end of the outermost cooling pipe.

[0010] Preferably, an air dryer is arranged in the outermost cooling pipe near the ventilation door.

[0011] Preferably, a circulating ventilation conversion device is also arranged in the temperature-reducing pipe system.

[0012] Preferably, the circulating ventilation conversion device is a mixed flow fan, a centrifugal fan, an axial flow fan or a blower fan.

[0013] Preferably, a temperature sensor is arranged inside the granary body.

[0014] Beneficial effects of the present invention:

[0015] 1. The present invention adopts a structure in which the tubes are nested and there is a gap between the tubes by controlling the temperature-reducing pipe system. Valves are arranged at both ends of the gap between the tubes. When the temperature inside the granary is too high, the valve between the outer tube and the inner tube is opened, that is, the outer tube and the inner tube are connected to the inside of the granary at the same time. At this time, the temperature outside the temperature-reducing pipe system is lower than the temperature inside. At the same time, the air temperature inside the granary is different from the temperature of the grain. Due to the temperature difference, the air in the inner tube and the outer tube forms a circulation, which promotes the circulation of the air inside the granary and reduces the temperature inside the grain. At this time, the temperature-reducing pipe system realizes the circulation function while also reducing the temperature of the granary, thereby improving the storage quality of the grain. When the temperature inside the granary is at the standard value, the valve between the outer tube and the inner tube is closed, and a closed space is formed between the outer tube and the inner tube, which is equivalent to forming a thermal insulation layer, reducing the influence of the external temperature on the gas in the tube. At this time, the temperature-reducing pipe system only plays a role in ensuring the air circulation inside the granary.

[0016] In addition, when the difference between the air temperature of the outer wall of the outer tube and the air temperature of the inner tube is large, the air in the inner tube will usually condense into water droplets attached to the inner wall of the inner tube when it is cold, and the air humidity in the granary will increase, which will affect the dryness of the grain and the storage quality of the grain. When the first valve and the second valve of the present invention are closed, a closed space is formed between the outer tube and the inner tube, which is similar to the principle of "hollow glass", reducing the influence of the external temperature on the gas in the tube, that is, when the temperature difference between the inside and outside of the granary is large, condensation will not occur.

[0017] The number of inner tubes of the present invention can be adjusted according to demand. When the granary is large and the temperature inside the tube needs to be adjusted more accurately, the number of inner tubes can be increased, and valves can be arranged at both ends of the gap between adjacent inner tubes. By controlling the opening and closing of the valves, the temperature inside the granary can be controlled more accurately.

[0018] 2. A vacuum pump interface is arranged on the outermost cooling tube of the present invention. When the valve is closed and a closed space is formed between the inner tube and the outer tube, a vacuum pump is connected to the vacuum pump interface to evacuate the space between the inner tube and the outer tube, thereby minimizing the influence of the external temperature on the inside of the tube.

[0019] 3. A ventilation door is arranged on the outer wall of the lower end of the outermost cooling pipe of the present invention, and an air dryer is arranged in the outer pipe near the ventilation door. When the temperature in the granary is too high, the ventilation door can be opened directly, and the cold air flows into the granary after being dried by the air dryer, thereby realizing rapid cooling of the granary.

[0020] 4. A circulating ventilation conversion device is also arranged in the cooling pipe system of the present invention, which can promote the circulation ventilation and cooling ventilation.

[0021] 5. A temperature sensor is arranged inside the granary body of the present invention, so that the temperature inside the granary can be observed in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0029] Specific implementation method 1: Reference Figure 1 and Figure 2 To illustrate this implementation, this implementation proposes the following technical solutions:

[0030] A granary with a cooling pipe comprises a granary body 1 and a cooling pipe system 2, wherein the upper and lower ends of the cooling pipe system 2 are respectively connected to the side walls of the granary body 1 and communicate with the interior of the granary body 1, the cooling pipe system 2 is two-layered, and the cooling pipe system 2 comprises an outer pipe 3 and a first inner pipe 4, wherein the upper and lower ends of the outer pipe 3 are respectively connected to the side walls of the granary body 1 and communicate with the interior of the granary body 1, and the upper and lower ends of the first inner pipe 4 are respectively connected to the side walls of the granary body 1, wherein the cooling pipe system 2 comprises an outer pipe 3 and a first inner pipe 4, wherein the upper and lower ends of the outer pipe 3 are respectively connected to the side walls of the granary body 1 and communicate with the interior of the granary body 1, and the upper and lower ends of the first inner pipe 4 are respectively connected to the side walls of the granary body 1, wherein the cooling pipe system 2 comprises an outer pipe 3 and a first inner pipe 4, wherein the upper and lower ends of the outer pipe 3 are respectively connected to the side walls of the granary body 1, and ... The upper end is connected to the interior of the granary body 1, and the lower end does not extend into the side wall of the granary body 1. The gaps between the outer tube 3 and the first inner tube 4 are respectively provided with a first valve 5 and a second valve 6; the first valve 5 and the second valve 6 are openable valves; a vacuum pump interface 7 is provided on the outer wall of the outer tube 3; a ventilation door 8 is provided on the outer wall of the lower end of the outer tube 3; an air dryer 10 is provided near the ventilation door 8 in the outer tube 3; a circulating ventilation conversion device 9 is also provided in the temperature-reducing pipe system 2. The circulating ventilation conversion device 9 of this embodiment adopts a mixed flow fan; a temperature sensor 11 is provided inside the granary body 1.

[0031] The temperature of the air and the grain inside the granary body 1 are observed by the temperature sensor 11 inside the granary body 1. When the temperature is too high, the first valve 5 and the second valve 6 are opened, that is, the outer tube 3 and the first inner tube 4 are connected to the inside of the granary body 1 at the same time. At this time, the temperature outside the temperature-reducible pipe system 2 is lower than the temperature inside. At the same time, the air temperature in the granary body 1 is different from the temperature of the grain. Due to the temperature difference, the air in the first inner tube 4 and the outer tube 3 forms a circulation, which promotes the circulation of the air inside the granary and reduces the temperature inside the grain. If the circulation ventilation conversion device 9, that is, the mixed flow fan, is turned on, the gas circulation in the pipe can be promoted. At this time, the temperature-reducible pipe system 2 can realize the circulation function while also reducing the temperature of the granary, thereby improving the storage quality of the grain; if rapid cooling is required, the ventilation door 8 can be opened, and the cold air can enter the temperature-reducible pipe system 2 after being dried by the air dryer 10, so that the air in the granary and the grain can be quickly cooled. Drying the cold air can prevent the grain from getting damp and mildewing, which affects the storage quality of the grain.

[0032] When the temperature inside the granary body 1 is at the standard value, the first valve 5 and the second valve 6 are closed, and a closed space is formed between the outer tube 3 and the first inner tube 4, which is equivalent to forming a thermal insulation layer, reducing the influence of the external temperature on the gas in the tube. The vacuum pump is connected to the vacuum pump interface 7, and the space between the outer tube 3 and the first inner tube 4 is evacuated to minimize the influence of the external temperature on the tube. At this time, the cooling pipe system 2 only serves to ensure the air circulation in the granary body 1. If the circulating ventilation conversion device 9, that is, the mixed flow fan, is turned on, the gas circulation in the tube can be promoted.

[0033] Specific implementation method 2: Reference Figure 3 and Figure 4 To illustrate this implementation, this implementation proposes the following technical solutions:

[0034] A granary with a cooling pipe, comprising a granary body 1 and a cooling pipe system 2, wherein the upper and lower ends of the cooling pipe system 2 are respectively connected to the side walls of the granary body 1 and are in communication with the interior of the granary body 1, the cooling pipe system (2) is three-layered, and the cooling pipe system (2) comprises an outer pipe (3), a first inner pipe (4) and a second inner pipe (14), wherein the upper and lower ends of the outer pipe (3) are respectively connected to the side walls of the granary body (1) and are in communication with the interior of the granary body (1), the upper and lower ends of the first inner pipe (4) and the second inner pipe (14) are respectively connected to the side walls of the granary body (1), the upper ends thereof are in communication with the interior of the granary body (1), and the lower ends thereof do not extend into the granary body. The side wall of the silo body (1), the gaps between the outer tube (3) and the first inner tube (4) are respectively provided with a first valve (5) and a second valve (6), the gaps between the first inner tube (4) and the second inner tube (14) are respectively provided with a third valve (12) and a fourth valve (13); the first valve 5, the second valve 6, the third valve (12) and the fourth valve (13) are valves that can be opened; a vacuum pump interface 7 is provided on the outer wall of the outer tube 3; a ventilation door 8 is provided on the outer wall of the lower end of the outer tube 3; an air dryer 10 is provided in the outer tube 3 near the ventilation door 8; a circulating ventilation conversion device 9 is also provided in the temperature-reducing pipe system 2. The circulating ventilation conversion device 9 of this embodiment adopts a centrifugal fan; a temperature sensor 11 is provided inside the silo body 1.

[0035] The temperature of the air inside the granary body 1 and the temperature of the grain are observed by the temperature sensor 11 inside the granary body 1 . When the temperature is too high, the first valve 5, the second valve 6, the third valve 12 and the fourth valve 13 are opened, that is, the outer tube 3, the first inner tube 4 and the second inner tube 14 are connected to the inside of the granary body 1 at the same time. At this time, the temperature outside the cooling pipe system 2 is lower than the temperature inside. At the same time, the air temperature in the inner part of the granary body 1 is different from the temperature of the grain. Due to the temperature difference, the air in the outer tube 3, the first inner tube 4 and the second inner tube 14 forms a circulation, which promotes the circulation of air inside the granary and reduces the temperature inside the grain. If the circulating ventilation conversion device 9, that is, the mixed flow fan, is opened, the gas circulation in the tube can be promoted. At this time, the cooling pipe system 2 can realize the circulation function while also reducing the temperature of the granary, thereby improving the storage quality of the grain; if the temperature difference required for cooling is not high, you can choose to only open the first valve 5 and the second valve 6 or only open the third valve 12 and the fourth valve 13, so that the diameter of the gas flow is small, and slow cooling can be achieved; the advantage of the cooling pipe system 2 is that the opening and closing of different valves can be controlled according to actual needs to achieve control of the cooling speed. If rapid cooling is required, the ventilation door 8 can be opened. After the cold air is dried by the air dryer 10, it enters the cooling pipe system 2, which can achieve rapid cooling of the air and grain inside the granary. Drying the cold air can prevent the grain from getting damp and mildewing, which affects the storage quality of the grain.

[0036] When the temperature inside the granary body 1 is at the standard value, the first valve 5 and the second valve 6 are closed, and a closed space is formed between the outer tube 3 and the first inner tube 4, which is equivalent to forming a thermal insulation layer, reducing the influence of the external temperature on the gas in the tube. The vacuum pump is connected to the vacuum pump interface 7, and the space between the outer tube 3 and the first inner tube 4 is evacuated, which can reduce the influence of the external temperature on the inside of the tube to a very low level. At this time, the cooling pipe system 2 only plays a role in ensuring the air circulation in the granary body 1. If the circulating ventilation conversion device 9, that is, the mixed flow fan, is opened, the gas circulation in the tube can be promoted; if the third valve 12 and the fourth valve 13 are also closed, the influence of the external temperature on the inside of the tube can be further reduced.

The upper end is connected to the interior of the granary body 1, and the lower end does not extend into the side wall of the granary body 1.
