[0024] As Figs. 1-3 shown, the utility model embodiment provides a novel low-temperature grain storage warehouse, including warehouse body 1, cooler 2 which is arranged in warehouse body 1 and refrigeration unit 3 which is arranged outside warehouse body 1.

[0025] Cooler 2 is vertically erected in warehouse body 1 in the form of a plate, and its two sides are connected to the inner wall of warehouse body 1; cooler 2 includes air outlet 21 and air inlet 22 arranged vertically; one end of air outlet 21 and air inlet 22 is communicated, and the other end is respectively provided with air outlet 23 and air inlet 24; the inlet and outlet of refrigeration unit 3 are connected to air outlet 23 and air inlet 24 of cooler 2 through pipelines; and cooler 2 extends horizontally in the form of a wave.

[0026] In the embodiment, preferably, warehouse body 1 is in the form of a rectangle in cross section, so as to cooperate with cooler 2 in the form of a plate, to make the distance between the grain on both sides of the plate surface of cooler 2 and cooler 2 balanced, and to achieve better cooling effect.

[0027] Cooler 2 extends laterally in the form of a wave, passes through the center of the grain pile in warehouse body 1, and is detachably installed with the inner wall of warehouse body 1; in addition, the top cover of warehouse body 1 can be separated from the main body part, so that the grain storage warehouse can be installed and disassembled by a crane or other mechanism, and cooler 2 can be taken out to facilitate cleaning operation when the grain storage warehouse is cleaned.

[0028] Air outlet 21 and air inlet 22 of cooler 2 are preferably two separate parts; cooler 2 is detachably spliced vertically by air outlet 21 and air inlet 22, to facilitate replacement and installation of cooler 2.

[0029] Air outlet 21 and air inlet 22 can each include air collection channel 25 at both ends and a plurality of air pipes 26 between the two air collection channels 25; the plurality of air pipes 26 are arranged vertically, and extend horizontally at both ends to communicate with air collection channel 25.

[0030] The cold air from the air inlet 24 first enters the air collecting channel 25 of the air inlet channel 22 to be evenly distributed into several air pipes 26 of the air inlet channel 22, and then is collected into the air collecting channel 25 at the other end of the air inlet channel 22 from the other end of the air pipe 26. The air collecting channel 25 of the air inlet channel 22 enters the air collecting channel 25 of the air outlet channel 21, and then is evenly distributed into several air pipes 26 of the air outlet channel 21 to be collected into the air collecting channel 25 at the other end of the air outlet channel 21 from the air outlet 23.

[0031] The air collecting channel 25 plays a role of air collection and even distribution, and can also be used for abutting and mounting the air inlet channel 22 and the air outlet channel 21.

[0032] The structure of the spaced arrangement of the several air pipes 26 can reduce the manufacturing difficulty of the cooler, reduce the consumption of manufacturing materials, store grain in the gap, surround the air pipe 26 with grain, cool 360 degrees, have better cooling effect, and reduce the occupation of the storage volume of the warehouse body 1.

[0033] More preferably, all the air pipes 26 of the cooler 2 in the embodiment extend in a wave shape horizontally, and the wave shapes of adjacent air pipes 26 are opposite, thereby increasing the cooling area range of the cooler 2 and improving the uniformity and concentration of cooling.

[0034] In addition, the pipe diameters of all the air pipes 26 of the cooler 2 gradually increase from top to bottom to improve the pressure resistance of the lower air pipes 26. The more the grain accumulation, the greater the pressure inside the grain pile, especially near the bottom center of the grain pile. Therefore, the lower the air pipe 26, the greater the pressure it bears, and increasing the pipe diameter can improve the structural strength and pressure resistance of the air pipe 26. More preferably, the pipe diameter of the air pipe 26 can be increased while the wall thickness of the air pipe 26 is also increased.

[0035] In addition, the spacing distance between adjacent air pipes 26 gradually increases from bottom to top. In the grain storage warehouse, the closer to the bottom of the grain pile, the more difficult the heat dissipation, resulting in a higher temperature. Therefore, the spacing distance between the air pipes 26 corresponding to the air inlet channel 22 is small, and the more dense air pipes 26 can quickly take away more heat. The upper part of the grain pile is close to the top space of the grain storage warehouse, and the heat dissipation is relatively easy. Therefore, the air pipes 26 with a relatively large spacing distance can meet the grain cooling demand. In addition, through the design of different sparse and dense arrangements, the overall temperature of the grain pile can be balanced.

[0036] In the embodiment, the height of the air inlet channel 22 can be equal to or slightly greater than the height of the air outlet channel 21, for example, the height of the air inlet channel 22 is 3 / 2 times the height of the air outlet channel 21, to more preferably cope with the problem of high heat and large cooling demand at the bottom of the grain pile.

[0037] In the embodiment, the cooler 2 extends along the length direction of the bin body 1, and the wave height of the wave shape is 1 / 3-1 / 2 of the width of the bin body 1, so that the cooling direction of the cooler 2 can cover the central area of the grain pile.

[0038] Further, in order to save the consumption of manufacturing materials while achieving better cooling effect, the wave height of the cooler 2 is equal to 1 / 2 of the wavelength, so that when the air pipe 26 extends in a wave shape, the spacing between the adjacent air pipe 26 bodies is reasonably distributed, and the grain around the air pipe 26 can be reasonably and evenly cooled, so as to achieve the best cooling effect with the least material.

[0039] In addition, the air inlet channel 22 and the air outlet channel 21 are also provided with support plates 27, which are connected between the corresponding wave crests and wave troughs of adjacent air pipes 26 to support the air pipes 26. The support plates 27 can be provided with one or more, according to the size of the cooler 2 required to be set.

[0040] In addition, the support plates 27 can be provided with temperature monitoring boxes 28, which are provided with temperature sensors for monitoring the temperature of the grain pile, so as to adjust the air outlet power and air outlet temperature of the refrigeration unit 3 in time according to the measured temperature of the grain pile. The temperature monitoring boxes 28 are preferably provided on the two support plates 27 located at the middle positions of the air inlet channel 22 and the air outlet channel 21, and are preferably located at the middle positions of the vertical heights of the support plates 27, so as to monitor the temperature accumulation center positions of the grain pile corresponding to the air inlet channel 22 and the air outlet channel, and the temperature monitoring boxes 28 are located at the positions farthest from the air pipe 26 to avoid being affected by the air pipe 26.

[0041] The new low-temperature grain storage bin provided in the embodiment can effectively guide the heat in the grain pile out by extending the cooler 2 transversely through the inside of the grain pile in a wave shape, thereby reducing the temperature of the grain pile and the whole grain storage bin, and avoiding problems such as mold and deterioration of the grain.
