Problems solved by technology

However, in the hot summer in the south, even though the walls of the existing storage warehouses are relatively thick and have been insulated against moisture to a certain extent, the side facing the light of the storage warehouses has been exposed to the sun for a long time, and the outdoors continue to be in a high temperature state. The control device only cools down the reserved space above the grain, and the heat transfer is from high temperature to low temperature. In summer, the external temperature of the storage warehouse is high, and the surroundings of the entire storage warehouse will transfer heat to the inside, which will drive the temperature of the stored grain in the warehouse to rise, which is not conducive to Quality and Freshness of Stored Grain

Embodiment 1

[0021] Embodiment 1: as figure 1 , 2As shown, a temperature control system for a grain storage bin includes a temperature control device 2 arranged on one side of the storage bin 1 along the wall. The temperature control device is connected with an air outlet pipe 4 and a return pipe 5, both of which are It is arranged horizontally around the inner wall of the storage bin. On the air outlet pipe, there are several longitudinally extending branch outlet pipes 4 arranged at intervals. On the return pipe, there are several longitudinally extending branch return pipes 6 arranged at intervals. The branch outlet pipe and the branch return pipe interval distribution. The air outlet pipe is located in the upper middle part of the storage bin and is lower than the inspection door, and the return pipe is located at the bottom of the storage bin. Return ports 7 are arranged at intervals on the return pipe. Air outlet pipes and return pipes are arranged on all inner walls separated fro...

Embodiment 2

[0023] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as image 3 , 4 As shown, both the branch air duct and the branch return duct include an inner tube 10 and an outer tube 11 sleeved on the outside of the inner tube and bonded to the outer surface of the inner tube. The inner tube is densely covered with through holes 12 for air flow. The tube is densely covered with air guide holes integrally connected with the outer tube. The air guide holes include a cone part 8 and a hole part 9. The cone part is a conical surface structure protruding from the surface of the outer tube. Both sides of the cone part are integrated with the outer tube. Connected, the gap between the free end edge of the cone and the outer tube forms a hole, and the through hole on the inner tube corresponds to the cone.

[0024] Both the branch air pipe and the branch return pipe are composed of an inner pipe and an outer pipe. The inn...

Embodiment 3

[0025] Embodiment 3: The structure of this embodiment is basically the same as that of Embodiment 2, the difference is that, as Figure 5 As shown, the middle position of the cone is recessed along the direction of the generatrix of the cone and toward the direction of the inner tube, and the air guide groove 13 is in the shape of a cone surface, and the free end edge of the cone is in the shape of an "M". The middle position of the cone is extruded along the direction of the generatrix of the cone to form an air guide groove, so that the air guide groove has a conical surface. Due to the shape of the air guide groove, the free end edge of the cone part presents an "M" shape, and the air guide groove The plate that has been stamped into the cone can be squeezed by a roller with protrusions, and the protrusions on the roller can be used to form air guide grooves on the cone. The air guide groove divides the space inside the cone into left and right parts, and the air entering a...

Abstract

The invention relates to a grain storage bin, in particular to a temperature control system for the grain storage bin. The temperature control system of the grain storage bin includes a temperature control device arranged on one side of the storage bin, the temperature control device is connected with an air outlet pipe and a return pipe, and the air outlet pipe and the return pipe are arranged horizontally around the inner wall of the storage bin, A plurality of longitudinally extending branch air outlet pipes are arranged at intervals on the air outlet pipe, and a plurality of longitudinally extending branch return pipes are arranged at intervals on the return pipe, and the branch outlet air pipes and branch return pipes are arranged at intervals. The invention has the beneficial effects of being able to cool down the side close to the sunshine in high-temperature seasons, avoiding excessive local temperature differences in the storage warehouse, preventing grain deterioration, and the like.

Description

technical field [0001] The invention relates to a grain storage bin, in particular to a temperature control system for the grain storage bin. Background technique [0002] Existing grain storage warehouses are usually arranged in a centralized manner, but they are arranged at intervals. The length and width of the storage warehouses are usually several meters or even tens of meters. The height of the densely stacked grains in the storage warehouses is also four to five meters high. There is a reserved space for people to walk between the top of the storage bin and the top of the storage bin. A mat is laid on the top of the grain storage bin, and an inspection door is opened on the upper part of the storage bin. Personnel can enter the reserved space at the upper end of the storage bin through the inspection door In the space, walking on the mat is convenient for maintenance of internal equipment. However, existing storage bins of this type need to be provided with a tempera...
