Description

Technical Field

[0001] The utility model relates to supporting equipment for cooling bulk grain storage, in particular to a bulk grain cooling device. Background Art

[0002] About 70% of our soybeans are imported from Brazil. The soybeans are shipped to my country by ship. During the long shipping process, the soybeans produce a relatively high temperature, which can reach 50~60℃. If such high-temperature soybeans are directly shipped to the grain depot for storage, the high-temperature storage will have many adverse effects on the later storage.

[0003] The conventional cooling method for high-temperature soybeans is to use a high-power grain cooler to cool the soybeans in the warehouse so that the soybeans reach the appropriate storage temperature. However, the soybeans are already in a piled state at this time, and the porosity of the soybeans is relatively small, that is, the ventilation effect of the soybean grain pile is poor. The use of grain coolers will cause a lot of energy consumption, high cooling costs, and a long cooling and ventilation time, which will cause moisture and weight loss of the soybeans, reducing the profits of the storage company. Utility Model Content

[0004] The purpose of the utility model is to provide a bulk grain cooling device which can cool bulk grain during its storage.

[0005] In order to solve the above technical problems, the technical solution of a bulk grain cooling and temperature reduction device in the present invention is as follows:

[0006] A bulk grain cooling and temperature reduction device comprises a grain drum with a grain inlet at the upper end, and also comprises a grain dividing cone which is smaller at the upper end and larger at the lower end and is located inside the grain drum, a grain outlet is provided at the bottom of the grain drum corresponding to the bottom of the grain dividing cone, the grain dividing cone is a hollow cone shell structure, a cooling pipe which is heat-conductively connected to the grain dividing cone is provided on the inner wall of the grain dividing cone, a condensation water guide channel which extends from top to bottom along the outer cone surface of the grain dividing cone is provided on the grain dividing cone, a condensation water outlet is provided at the bottom of the condensation water guide channel, the upper end opening size of the condensation water guide channel is smaller than the size of the bulk grain or a grain retaining net is provided at the upper end opening of the condensation water guide channel, and a condensation water collecting tank which is communicated with the condensation water outlet is provided at the lower end of the grain drum on the lower side of the grain dividing cone.

[0007] Furthermore, the grain drum is connected to the upper end of the condensate collecting tank through a plurality of legs arranged at intervals along the circumferential direction, and the grain outlet is formed between two adjacent legs.

[0008] Furthermore, the grain drum and the grain distribution cone are coaxially arranged.

[0009] Furthermore, the condensed water collecting tank is a conical structure that is larger at the top and smaller at the bottom, and a condensed water outlet pipe is provided at the bottom of the condensed water collecting tank.

[0010] Furthermore, the cross-sectional shape of the condensate diversion channel is a "convex" shape with a small mouth and a large cavity. A plurality of condensate water outlets are provided at the bottom of each condensate diversion channel, and the condensate water outlets are spaced apart along the length direction of the condensate diversion channel.

[0011] Furthermore, a concave installation space is formed between adjacent condensate diversion channels, and the cooling pipe is distributed in the installation space. The cooling pipe is composed of multiple U-shaped cooling pipe sections connected end to end in sequence, and one U-shaped cooling pipe section is provided in each installation space.

[0012] The beneficial effects of the present invention are as follows: the bulk grain cooling and temperature reduction device in the present invention can be applied to a certain link in the bulk grain storage process, the bulk grain enters the grain drum through the grain inlet, and is automatically divided by the outer conical surface of the grain dividing cone. The bulk grain slides downward along the outer conical surface of the grain dividing cone by gravity, and finally flows out of the grain drum through the grain outlet.

The bulk grain is cooled by contact with the grain dividing cone for heat exchange, and the bulk grain will not fall into the condensate diversion channel. The condensed water generated by the heat exchange will flow downward through the condensate diversion channel, and finally enter the condensate collecting tank through the condensate outlet.

[0020] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] In the utility model, a bulk grain cooling and temperature reduction device is implemented as follows Figures 1 to 5 As shown:

[0023] It includes a grain barrel 2 with a grain inlet 1 at the upper end, and the grain inlet 1 is a conical structure with a small upper part and a large lower part. The bulk grain cooling and cooling device also includes a grain dividing cone 6 arranged on the inner side of the grain barrel and coaxial with the grain barrel. The grain dividing cone 6 is a hollow cone shell structure with a small upper part and a large lower part. A cooling pipe 11 is provided on the inner wall of the grain dividing cone and is thermally connected to the grain dividing cone.

[0024] The grain-distributing cone is equipped with multiple condensate diversion channels 8 extending from top to bottom along its outer surface. These channels are radially distributed around the upper axis of the cone. In this embodiment, the cross-section of the channels is a "convex" shape with a small opening and a large cavity. Each channel has multiple condensate outlets 7 at its base, spaced apart along its length.

[0025] An inwardly concave installation space 12 is formed between adjacent condensate diversion channels, and a cooling pipe 11 is distributed in the installation space 12. The cooling pipe 11 is composed of a plurality of U-shaped cooling pipe sections 13 connected end to end. The U-shaped cooling pipe section 13 is located on the inner side of the grain distribution cone, and each side wall of the installation space can form effective heat conduction. One U-shaped cooling pipe section is provided in each installation space 12. A thermal conductive adhesive is applied between the U-shaped cooling pipe section 13 and the inner wall of the installation space. In other words, cooling pipes are distributed on both sides and one end of each condensate diversion channel, ensuring the cooling effect on the grain distribution cone.

[0026] The upper opening of the condensate diversion channel 8 is located on the outer conical surface of the grain distribution cone. The upper opening of the condensate diversion channel is smaller than the size of the bulk grain to prevent the bulk grain from falling into the condensate diversion channel when sliding down the outer conical surface of the grain distribution cone. In other embodiments of the present invention, if the upper opening 10 of the condensate diversion channel is larger, a grain retaining net can be installed at the upper opening of the condensate diversion channel to prevent the bulk grain from falling into the condensate diversion channel when sliding down.

[0027] The lower end of the grain drum is provided with a condensate collection trough 4 connected to the condensate outlet on the lower side of the grain distribution cone. In this embodiment, the grain drum is connected to the upper end of the condensate collection trough by three circumferentially spaced legs 9, and the grain outlet 3 is formed between two adjacent legs.

[0028] The condensed water collecting tank is a conical structure with a larger upper portion and a smaller lower portion. A condensed water outlet pipe 5 is provided at the bottom of the condensed water collecting tank 4 .

[0029] When in use, this bulk grain cooling and cooling device can be applied to a certain link in the process of bulk grain entering the granary. For example, during the process of transporting bulk grain to the granary via a conveyor, the bulk grain first passes through the bulk grain cooling and cooling device, and then is transported to the granary via the conveyor; the bulk grain cooling and cooling device can also be set at the end of the conveying stroke of the conveyor, and after the bulk grain is transported to the bulk grain cooling and cooling device via the conveyor, it falls into the granary to form a grain pile.

[0030] Specifically, the bulk grain falls onto the grain distributing cone through the grain inlet, and the grain distributing cone evenly disperses the bulk grain to better realize the heat exchange between the bulk grain and the grain distributing cone. Cold water enters through the water inlet of the cooling pipe and then flows out through the water outlet of the cooling pipe. The cooling pipe exchanges heat with the grain distributing cone to reduce the temperature of the grain distributing cone. During the process of the bulk grain sliding down the outer cone surface of the grain distributing cone, the bulk grain is cooled by the grain distributing cone and then discharged through the grain outlet, thereby reducing the storage temperature of the bulk grain entering the warehouse. The condensed water generated by the heat exchange flows downward along the condensed water guide channel, minimizing the contact with the bulk grain and causing the increase of the humidity of the bulk grain. The condensed water flows through the condensed water outlet to the condensed water collection tank for collection, and then is discharged through the condensed water outlet pipe to ensure the long-term and effective use of the bulk grain cooling device.

[0031] In the above description of this specification, unless otherwise expressly specified or limited, terms such as "fixed," "mounted," "connected," or "connected" should be understood broadly. For example, the term "connected" can refer to a fixed connection, a removable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal connection between two components or the interaction between two components. Therefore, unless otherwise expressly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "center", "longitudinal", "lateral", "clockwise" or "counterclockwise", etc., which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0033] In addition, the terms "first" or "second" used in this specification to refer to numbers or ordinal numbers are used for descriptive purposes only and should not be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this specification, "plurality" means at least two, such as two, three or more, etc., unless otherwise clearly specified.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
