Description

Technical Field

[0002] Grain is one of the most important food resources for human beings. Every year, a large amount of grain needs to be stored for daily life. If grain is not stored properly, it will seriously affect the quality and nutritional value of grain, which will inevitably lead to waste of grain resources. Temperature is an important environmental factor that affects the quality of stored grain. Excessive grain pile temperature may cause grain fermentation, deterioration, pest breeding and other problems. Therefore, cooling grain is currently an important means of grain storage.

[0003] Traditional grain storage methods often rely on ventilation and cooling. However, this method has limited effectiveness in high temperature seasons or high humidity environments. It is difficult to achieve ideal storage temperature and humidity conditions inside the grain pile. Moreover, traditional ventilation and cooling may increase grain losses and energy consumption.

[0004] For example, the advantages of the horizontal air supply cooling method known to the inventor are uniform cooling, balanced humidity, and a wide range of trials, but it also has disadvantages such as poor upper effect, high energy consumption, and grain loss; and although bottom air supply has the advantages of energy saving and reducing pests, the humidity is difficult to control, the grain pile is unevenly cooled, and the control is complex.

[0005] Therefore, there is an urgent need for a grain storage method with better effects and lower energy and food losses to solve the above problems.

[0006] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

At the same time, real-time detection of temperature and humidity at each measuring point inside the grain pile can be performed to achieve efficient and high-quality grain storage, so as to solve the problems of difficult disassembly and maintenance and poor temperature control of existing grain storage cooling systems.

DETAILED DESCRIPTION

[0023] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", etc. involved in the present application are used to distinguish the objects described and do not have any order or technical meaning. The terms "connection" and "connection" involved in the present application, unless otherwise specified, include direct and indirect connections (connections).

[0025] Unless otherwise specified, the components, structures, mechanisms, sensors and other devices involved in the following embodiments are conventional commercially available products.

[0026] This example discloses a grain pile cold water pipe temperature control system, see Figure 1 , Figure 2, including a water circulation device and a cooling pipe 1; the water circulation device is arranged outside the grain pile, the cooling pipe 1 is arranged inside the grain pile and is correspondingly connected to the water circulation device, the structural shape of the cooling pipe 1 corresponds to the shape of the grain pile, and the cooling water can achieve continuous cooling of various parts of the grain pile through the cooling pipe 1.

[0027] See also Figure 1 The water circulation device includes a cooling tower 2, a water tank 3, a first water pump 4 and a second water pump 5; the water inlet end of the water tank 3 is connected to the cooling tower 2 through an inlet pipe 6 to store cooling water from the cooling tower 2 and provide sufficient cooling water of a preset temperature for the cooling pipeline 1 at any time; the water outlet end of the water tank 3 is connected to the first water pump 4 through an outlet pipe 7; since the inlet pipe 6 and the outlet pipe 7 are located outside the grain pile, in order to reduce the temperature change of the cooling water in the inlet pipe 6 or the outlet pipe 7, an insulation layer is wrapped on the outside of the inlet pipe 6 and the outlet pipe 7 to ensure the temperature regulation effect of the grain pile.

[0028] See also Figure 2 The water outlet of the first water pump 4 and the water inlet of the cooling tower 2 are correspondingly connected through the cooling pipe 1. The first water pump 4 can apply pressure to the system pipeline to make the cooling water in the water tank 3 pass through the cooling pipe 1 inside the grain pile and flow to the cooling tower 2. Since water has high thermal conductivity, the temperature inside the grain pile can be cooled while the cooling water passes through the inside of the grain pile; the cooling water after passing through the grain pile takes away the heat inside the grain pile, and the temperature of the cooling water increases. At this time, the cooling water flows to the cooling tower 2 for further cooling. A second water pump 5 is provided on the water inlet pipe 6 between the cooling tower 2 and the water tank 3, which is used to make the cooling water in the cooling tower 2 flow to the water tank 3 for storage again. At this point, the cooling water realizes a closed-loop flow in the entire cooling system. The circulating flow of cooling water reduces energy consumption and material costs while realizing continuous cooling of the grain pile.

[0029] See also Figure 2 The cooling pipe 1 is a copper pipe or aluminum alloy pipe with high thermal conductivity to achieve rapid temperature conversion of cooling water in the cooling pipe 1 and improve the cooling effect of the grain pile; the cooling pipe 1 includes several cooling single pipes. To adapt to the shapes and sizes of different grain piles, the length of each cooling single pipe is 1m or 1.5m, which is much smaller than the size of the grain pile. Therefore, according to actual needs, the appropriate number and length of cooling single pipes can be selected for flexible combination and arrangement, so that the cooling pipe 1 is evenly distributed to various parts of the grain pile, so that the various parts of the grain pile are evenly cooled, making the cooling system more universal and practical; see Figure 3 Each section of the cooling single pipe is connected by an elbow 8 or a clamp 9. The clamp 9 is easy to disassemble and assemble, making the installation and maintenance of the cooling pipe 1 simple, and helping the cooling pipe 1 to be flexibly arranged and installed according to different grain piles.

[0030] The cooling pipeline 1 includes a main pipe and a branch pipe. Since the flow in the main pipe is large and the flow in the branch pipe is relatively small, a reducing ring is provided at the connection between the main pipe and the branch pipe to allow the cooling water to be evenly diverted to each branch pipe, ensuring that the cooling water can evenly penetrate the grain pile to achieve effective and uniform cooling.

[0031] See also Figure 2 A plurality of temperature sensors and humidity sensors 10 are provided on the cooling pipeline 1 at different positions inside the grain pile, which can monitor the temperature and humidity environment of different positions of the grain pile in real time. Flow valves 11 are provided on both sides of the first water pump 4 and both sides of the water tank 3, respectively. The cooling tower 2, the water pump and the flow valve 11 can be adjusted manually or automatically according to the temperature and humidity environment inside the grain pile, and the flow and temperature of the cooling water passing through the grain pile can be accurately controlled to ensure that the interior of the grain pile is maintained in an ideal state and improve the quality of stored grain.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
