Detailed Embodiment

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Please refer to Figure 1 and Figure 2, the multi - stage cooling device for producing organic fertilizers provided by the present utility model will be described hereinafter. The multi - stage cooling device for producing organic fertilizers includes a base 10, a material conveying cylinder 20, a rotating tube 30, a jacket 40, a driving structure 50, and a refrigeration module 60. The material conveying cylinder 20 is inclined and arranged on the base 10, having a cylinder cavity 21. The bottom end of the material conveying cylinder 20 is provided with a feed inlet 22 communicating with the cylinder cavity 21, and the top end is provided with a discharge outlet 23 communicating with the cylinder cavity 21. The rotating tube 30 is rotatably arranged on the material conveying cylinder 20, and its axis is collinear with the axis of the cylinder cavity 21. Both ends of the rotating tube 30 extend out of the material conveying cylinder 20. A sealing plug is provided at the bottom end of the rotating tube 30. A spiral blade is wound around the rotating tube 30. An air outlet part communicating with the cylinder cavity 21 is provided on the side wall of the rotating tube 30. The jacket 40 is arranged around the material conveying cylinder 20, enclosing a refrigerant space with the material conveying cylinder 20. The driving structure 50 is power - connected to the bottom end of the rotating tube 30. The refrigeration module 60 is connected to the top end of the rotating tube 30 and can inject cold air into the rotating tube 30.

[0031] In the multi - stage cooling device for producing organic fertilizers provided in this embodiment, compared with the prior art, the combination of the material conveying cylinder 20, the rotating tube 30, and the driving structure 50 forms a screw conveyor, which can ensure the conveyance of the incoming organic fertilizers. The arrangement of the jacket 40 can ensure that the temperature of the side wall of the material conveying cylinder 20 is reduced, and thus, during the contact with the organic fertilizers, the organic fertilizers are cooled. An air outlet part is provided on the rotating tube 30, and the rotating tube 30 is connected to the refrigeration module 60, which can ensure that cold air is released into the cylinder cavity 21 through the air outlet part. Further, the organic fertilizers are cooled in the cylinder cavity 21, and the heat is timely sent out of the cylinder cavity 21. This structure can avoid the loss of cold quantity, improve the cooling efficiency, and ensure the cooling effect, with strong practicability.

[0032] It can be seen Figure 3 , regarding the inclined arrangement of the material conveying cylinder 20, multiple multi - stage cooling devices for producing organic fertilizers provided in this embodiment can be provided at the same time, and each multi - stage cooling device for producing organic fertilizers is connected in series in sequence, that is, the discharge outlet 23 of the previous multi - stage cooling device for producing organic fertilizers corresponds to the feed inlet 22 of the next multi - stage cooling device for producing organic fertilizers, realizing multi - stage cooling, extending the cooling stroke, and ensuring the cooling effect.

[0033] In some embodiments, the above - mentioned base 10 can adopt the structure as Figure 1 shown. Refer to Figure 1 , a bracket 11 for installing the material conveying cylinder 20 is provided on the base 10, and the arrangement of the bracket 11 can ensure the stable support of the material conveying cylinder 20.

[0034] In some embodiments, the above - mentioned refrigeration module 60 can adopt the structure as Figure 1 and Figure 2 shown. Refer to Figure 1 and Figure 2, the refrigeration module 60 includes an air conditioner unit 61, a delivery pipeline 62, and a connection structure 63. The air conditioner unit 61 has an air outlet. One end of the delivery pipeline 62 is communicated with the air outlet. The connection structure 63 is arranged on the material transfer cylinder 20 and is communicated with the other end of the delivery pipeline 62. The connection structure 63 is rotatably connected to the top end of the rotating pipe 30.

[0035] The air conditioner unit 61 can ensure refrigerating the air and simultaneously releasing cold air, which is delivered to the rotating pipe 30 through the delivery pipeline 62 and the connection structure 63, so as to ensure that the cold air is ejected from the air outlet part into the cylinder cavity 21, while cooling the organic fertilizer, the heat is taken out in time.

[0036] It should be noted that, in order to ensure the flow rate of the cold air, a booster pump can be arranged on the delivery pipeline 62.

[0037] In some embodiments, the above-mentioned refrigeration module 60 can adopt a structure such as Figure 1 and Figure 2 shown. Refer to Figure 1 and Figure 2 , the connection structure 63 is a sleeve, the sleeve is coaxially arranged with the rotating pipe 30, and the sleeve is fixedly arranged on the material transfer cylinder 20. A sealing bearing 64 is arranged between the sleeve and the rotating pipe 30.

[0038] The arrangement of the sleeve can ensure connecting the delivery pipeline 62 and the rotating pipe 30, and can ensure the rotational connection with the rotating pipe 30, thereby ensuring the stability of cold air delivery.

[0039] In some embodiments, the above-mentioned jacket 40 can adopt a structure such as Figure 1 shown. Refer to Figure 1 , the bottom end of the jacket 40 is provided with an inlet communicated with the refrigerant space, and the top end is provided with an outlet communicated with the refrigerant space.

[0040] Among them, the inlet and outlet of the jacket 40 are externally connected to a circulating cold water supply module.

[0041] The externally connected circulating cold water supply module can deliver cold water into the refrigerant space, thereby ensuring that the refrigerant space is filled with cold water, increasing the area of the cooling surface, and ensuring the cooling effect.

[0042] Regarding the circulating cold water supply module, the existing technology can be adopted, that is, it includes a water tank, a circulating pipeline, a water pump, and a refrigerator in the water tank. This technology is the existing technology and will not be elaborated here.

[0043] In some embodiments, the above-mentioned material transfer cylinder 20 can adopt a structure such as Figure 1 shown. Refer to Figure 1, a plurality of exhaust pipes 24 are provided on the material transfer cylinder 20, and the exhaust pipes 24 are arranged at intervals along the extending direction of the material transfer cylinder 20. One end of each exhaust pipe 24 communicates with the cylinder cavity 21, and the other end extends upward after passing through the jacket 40. When the cold air derived from the air outlet part contacts the organic fertilizer, the organic fertilizer is cooled, and the increased air pressure needs to be discharged. At this time, the cold air carrying heat can be discharged to the outside of the cylinder cavity 21 through the exhaust pipes 24 in time, so as to ensure the cooling effect.

[0044] In some embodiments, the above-mentioned air outlet part can adopt, for example Figure 1 the structure shown. Refer to Figure 1 , the air outlet part includes a plurality of air outlets 31 arranged at intervals along the spiral cavity formed by the spiral blades, and the interval distance between the air outlets 31 gradually decreases from bottom to top.

[0045] The interval distance of each air outlet 31 mentioned here refers to the distance between any two adjacent air outlets 31. The air outlet 31 can ensure that the cold air in the rotating pipe 30 is directly output into the cylinder cavity 21 to ensure full contact with the organic fertilizer, thereby ensuring the cooling efficiency and avoiding the loss of cold. Regarding the density of each air outlet 31 gradually decreasing from bottom to top, it can ensure that the air output gradually decreases from bottom to top. Since the temperature of the incoming organic fertilizer is relatively high and the temperature gradually decreases during the cooling process, this structure can ensure that according to the temperature of the organic fertilizer, through this kind of hierarchical cooling, the temperature of the organic fertilizer at the bottom of the cylinder cavity 21 is high and the cold quantity is large; the temperature of the organic fertilizer at the top is low and the cold quantity is small, while also avoiding the loss of cold and ensuring the full utilization of cold air.

[0046] In some embodiments, the above-mentioned driving structure 50 can adopt, for example Figure 1 the structure shown. Refer to Figure 1 , the driving structure 50 includes a driver, and the driver is fixedly arranged at the bottom end of the material transfer cylinder 20 and is connected to the bottom end of the rotating pipe 30. The driver can be a driving motor, which can mainly ensure the driving of the rotating pipe 30, so as to ensure that the organic fertilizer is pushed and conveyed by the spiral blades.

[0047] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
