Description

Technical Field

[0001] The present application relates to the technical field of organic fertilizer processing, and particularly relates to a cooling device for organic fertilizer production. Background Art

[0002] Organic fertilizers are applied to the soil to provide carbon-containing materials for plants. When organic fertilizers are processed and produced, they need to be dried and cooled after drying.

[0003] The existing cooling method for organic fertilizers is mainly water cooling. Cold water is passed through the hollow side walls of the cooling box in a flowing manner to form a cold source on the side walls of the cooling box. A stirring structure is rotatably arranged in the middle of the cooling box, and the stirring structure is used to stir the organic fertilizer. With the assistance of the stirring structure, the organic fertilizer exchanges heat with the side walls of the cooling box to achieve the cooling of the organic fertilizer.

[0004] In the above cooling scheme, it is difficult for the stirring structure to stir the organic fertilizer located in the middle of the cooling box close to the side walls of the cooling box, resulting in the organic fertilizer at the middle position of the cooling box being not easily cooled, and thus the overall cooling effect of the organic fertilizer in the cooling box is poor. Utility Model Content

[0005] In order to improve the overall cooling effect of organic fertilizers, the present application provides a cooling device for organic fertilizer production.

[0006] A cooling device for organic fertilizer production provided by the present application adopts the following technical solution:

[0007] A cooling device for organic fertilizer production includes a cooling box with hollow side walls, a water cooling component, and an air cooling component. The water cooling component is used to introduce running water into the interior of the side walls of the cooling box. The air cooling component includes an air cooling pipe and a cold air blower. The air cooling pipe is arranged at the central position inside the cooling box. A plurality of first air blowing holes are formed in the side wall of the air cooling pipe along the circumferential and axial directions. One end of the air cooling pipe is sealed, and the cold air blower is communicated with the other end of the air cooling pipe.

[0008] By adopting the above technical solution, the water cooling component introduces running water into the interior of the side walls of the cooling box to form a water cooling cold source on the side walls of the cooling box. The cold air blower blows cold air into the air cooling pipe, and the cold air blows into the cooling box from the first air blowing holes. On the one hand, the cold air forms an air cooling cold source on the air cooling pipe. On the other hand, the cold air can directly blow on the organic fertilizer, enabling the organic fertilizer close to the side walls of the cooling box to exchange heat with the water cooling cold source, enabling the organic fertilizer located at the central position of the cooling box to exchange heat with the air cooling cold source, and the cold air can cool the organic fertilizer in the middle of the side walls of the cooling box and the air cooling pipe. Thus, the organic fertilizer as a whole can directly exchange heat with the cold source for cooling, improving the overall cooling effect of the organic fertilizer.

[0009] Optionally, the top end of the cooling box tapers, and a feed pipe is connected thereto. The top end of the air-cooling pipe is a sealed end and is tapered. A plurality of second air-blowing holes are provided in the circumferential and axial directions of the sealed end of the air-cooling pipe, and the second air-blowing holes face the conical surface at the top end of the cooling box.

[0010] By adopting the above technical solution, the cold air in the air-cooling pipe can be blown out from the second air-blowing holes and blow towards the conical surface at the top end of the cooling box. After the organic fertilizer is loaded into the cooling box from the feed pipe, the cold air blown out from the second air-blowing holes can preliminarily air-cool the organic fertilizer and can blow the organic fertilizer to impact on the conical surface at the top end of the cooling box, so that the organic fertilizer can be impact-crushed, improving the dispersion degree of the organic fertilizer.

[0011] Optionally, the water-cooling component includes a water tank and a water pump. The water tank is used for storing water. The water inlet of the water pump is communicated with the bottom of the water tank, and the water outlet is communicated with the outer wall of the side wall of the cooling box through a water outlet pipe. A return pipe is connected between the water tank and the outer wall of the side wall of the cooling box.

[0012] By adopting the above technical solution, the water pump can pump the water in the water tank into the side wall of the cooling box and make the water flow back into the water tank from the return pipe, so that the water inside the side wall of the cooling box can form a cold source in the form of flowing water.

[0013] Optionally, the bottom end of the cooling box is hollow and communicated with the side wall of the cooling box. The bottom end of the air-cooling pipe rotatably penetrates through the bottom end of the cooling box and is rotatably connected with a cold air blower. The cold air blower is fixedly connected to the bottom end of the cooling box. A plurality of blades are fixedly provided on the air-cooling pipe along the direction of its rotation axis. A plurality of blades are all located inside the bottom end of the cooling box. The water outlet pipe is communicated with the bottom end of the outer wall of the side wall of the cooling box, and the pipe orifice of the water outlet pipe faces one side of the rotation axis of the air-cooling pipe.

[0014] By adopting the above technical solution, since the pipe orifice of the water outlet pipe faces one side of the rotation axis of the air-cooling pipe, the water flow flowing out from the water outlet pipe can impact on the blades, so that the blades can rotate around the rotation axis of the air-cooling pipe. The blades can drive the air-cooling pipe to rotate, and the air-cooling pipe drives the cold air flow blown out from the first air-blowing holes to rotate. The cold air flow can cool the organic fertilizer in the rotating state, improving the air-cooling effect.

[0015] Optionally, a spiral stirring plate is coaxially sleeved on the air-cooling pipe. The spiral stirring plate is fixedly connected with the air-cooling pipe. A gap is left between the spiral stirring plate and the outer side wall of the air-cooling pipe and the inner wall of the side wall of the cooling box.

[0016] By adopting the above technical solution, the spiral stirring plate can rotate along with the air-cooling pipe. Since a gap is left between the spiral stirring plate and the outer side wall of the air-cooling pipe and the inner wall of the side wall of the cooling box, the spiral stirring plate can turn over the organic fertilizer in the middle of the side wall of the cooling box and the side wall of the air-cooling pipe during the rotation process, further improving the overall cooling effect of the organic fertilizer.

[0017] Optionally, a spiral guide plate is coaxially arranged inside the side wall of the cooling box.

[0018] By adopting the above technical solution, the spiral guide plate extends the flow path of the water flow inside the side wall of the cooling box, prolongs the contact time between the water flow and the organic fertilizer, and enables the full utilization of the cold energy of the water flow.

[0019] Optionally, the rotation direction of the spiral stirring plate and the rotation direction of the spiral guide plate are both the same as the rotation direction of the air-cooling pipe.

[0020] By adopting the above technical solution, setting the rotation direction of the spiral stirring plate and the rotation direction of the spiral guide plate to be the same as the rotation direction of the air-cooling pipe, on the one hand, reduces the load of the rotation of the air-cooling pipe, making it easier for the water flow to drive the air-cooling pipe to rotate, and on the other hand, preventing the water flow from flowing backward inside the bottom end of the cooling box.

[0021] Optionally, a refrigerator is arranged on the water tank, and the refrigerator is used to cool the water in the water tank.

[0022] By adopting the above technical solution, the refrigerator can cool the water in the water tank, making it easier for the water flowing into the inside of the side wall of the cooling box to maintain its cooling capacity.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the water-cooling component and the air-cooling component, cold sources can be formed on both the side wall and the inner central position of the cooling box, thereby improving the overall cooling effect of the organic fertilizer;

[0025] 2. By setting the blades and the spiral stirring plate, the organic fertilizer in the cooling box can be turned over, further improving the overall cooling effect of the organic fertilizer;

[0026] 3. By setting the spiral guide plate, the contact time between the water flow and the organic fertilizer is prolonged, so that the cold energy of the water flow can be fully utilized. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following further elaborates on this application in conjunction with the attached Figure 1-2 drawings.

[0032] An embodiment of this application discloses a cooling device for organic fertilizer production. Referring to Figure 1 and Figure 2 , a cooling device for organic fertilizer production includes a cooling box 1 with a hollow side wall, a water cooling component 2 and an air cooling component 3. The water cooling component 2 is used to introduce flowing water into the inner side wall of the cooling box 1, and the air cooling component 3 is arranged at the central position inside the cooling box 1 and is used to form a cold source at the central position inside the cooling box 1.

[0033] During use, the organic fertilizer is loaded into the cooling box 1. The organic fertilizer near the side wall of the cooling box 1 exchanges heat with the flowing water, and the organic fertilizer near the central position of the cooling box 1 exchanges heat with the cold source formed by the air cooling component 3, thereby improving the overall cooling effect of the organic fertilizer.

[0034] Referring to Figure 2 , the cooling box 1 is in the shape of a circular box and is vertically arranged. The top end of the cooling box 1 tapers to a conical shape and is coaxially connected to a circular tubular feed pipe 11. The bottom end of the cooling box 1 is hollow and is connected to the side wall of the cooling box 1.

[0035] Referring to Figure 1 , the water cooling component 2 includes a water tank 21 and a water pump 22. The water tank 21 is in the shape of a rectangular box and is vertically arranged. The water tank 21 is located on one side of the cooling box 1 and is used to store water.

[0036] The water pump 22 is located between the water tank 21 and the cooling box 1. The water inlet of the water pump 22 is connected to the bottom of the water tank 21, and the water outlet is connected to the outer wall of the side wall of the cooling box 1 through an outlet pipe 23. The outlet pipe 23 is in the shape of a circular tube and is connected to the bottom end of the outer wall of the side wall of the cooling box 1.

[0037] Referring to Figure 1 and Figure 2 , the top end of the water tank 21 and the top of the outer wall of the side wall of the cooling box 1 are connected by a return pipe 24. The return pipe 24 is in the shape of a circular tube. A spiral guide plate 25 is coaxially arranged inside the side wall of the cooling box 1. The inner side of the spiral guide plate 25 is attached to and fixedly connected to the inner wall of the side wall of the cooling box 1, and the outer side of the spiral guide plate 25 is attached to and fixedly connected to the outer wall of the side wall of the cooling box 1. The spiral guide plate 25 guides the water flow to spiral upward.

[0038] Referring to Figure 1 , on the side of the water tank 21 away from the cooling tank 1, a refrigerator 26 is fixedly installed, and the refrigerator 26 is used to cool the water in the water tank 21.

[0039] During use, the water pump 22 is started. The water pump 22 pumps the water in the water tank 21 and flows it into the interior of the bottom end of the cooling tank 1 through the water outlet pipe 23. The water flow flows along the spiral guide plate 25 inside the side wall of the cooling tank 1 and returns to the water tank 21 through the return pipe 24. The refrigerator 26 cools the water in the water tank 21, so that both the bottom end and the side wall of the cooling tank 1 form a water-cooled heat source, so that the organic fertilizer close to the side wall of the cooling tank 1 can perform heat exchange to be cooled.

[0040] Referring to Figure 1 and Figure 2 , the air-cooling assembly 3 includes an air-cooling pipe 31 and a cold air blower 32. The air-cooling pipe 31 is in a circular tubular shape and is coaxially arranged inside the cooling tank 1. The top end of the air-cooling pipe 31 is sealed and is conical. The bottom end of the air-cooling pipe 31 rotatably penetrates through the bottom end of the cooling tank 1.

[0041] Referring to Figure 1 , the cold air blower 32 is located at the bottom end of the cooling tank 1 and is fixedly connected to the bottom end of the cooling tank 1. The air outlet of the cold air blower 32 is communicated with the bottom end of the air-cooling pipe 31 and is used to blow cold air into the air-cooling pipe 31. The cold air blower 32 is rotatably connected to the air-cooling pipe 31.

[0042] Referring to Figure 2 , a plurality of first air blowing holes 311 are formed in the side wall of the air-cooling pipe 31 in both the circumferential direction and the axial direction. The first air blowing holes 311 are circular and penetrate through the wall thickness of the air-cooling pipe 31.

[0043] A plurality of second air blowing holes 312 are formed in the top end of the air-cooling pipe 31 in both the circumferential direction and the axial direction. The second air blowing holes 312 are circular and penetrate through the wall thickness of the air-cooling pipe 31. The second air blowing holes 312 face the conical surface at the top end of the cooling tank 1.

[0044] A plurality of blades 33 are fixedly arranged on the air-cooling pipe 31 evenly in the direction of its rotation axis. The plurality of blades 33 are all located inside the bottom end of the cooling tank 1. The blades 33 are in a rectangular sheet shape. The width direction of the blades 33 is parallel to the axis direction of the air-cooling pipe 31, and the length direction of the blades 33 is parallel to the diameter direction of the cooling tank 1. The pipe orifice of the water outlet pipe 23 faces one side of the rotation axis of the air-cooling pipe 31 and is arranged opposite to some of the blades 33.

[0045] A spiral stirring plate 34 is coaxially sleeved on the air-cooling pipe 31. The bottom end of the spiral stirring plate 34 is fixedly connected to the air-cooling pipe 31. There is a gap between the inner side of the spiral stirring plate 34 and the outer side wall of the air-cooling pipe 31, and there is a gap between the outer side of the spiral stirring plate 34 and the inner wall of the side wall of the cooling tank 1.

[0046] The rotation direction of the spiral stirring plate 34 and the spiral guide plate 25 is consistent with the rotation direction of the air-cooling pipe 31.

[0047] During use, start the cooling fan 32. The cooling fan 32 blows cold air into the air-cooling pipe 31 to form an air-cooling heat source in the air-cooling pipe 31, so that the organic fertilizer near the air-cooling pipe 31 can conduct heat exchange. The cold air blows out from the first air-blowing holes 311 and the second air-blowing holes 312. The cold air blowing out from the second air-blowing holes 312 initially cools and impacts and crushes the organic fertilizer, and the cold air blowing out from the first air-blowing holes 311 air-cools the organic fertilizer. The water flow impacts on the blades 33 and drives the blades 33 to rotate. The blades 33 drive the air-cooling pipe 31 to rotate. The air-cooling pipe 31 drives the spiral stirring plate 34 and the cold air flow blowing out from the first air-blowing holes 311 to rotate. The spiral stirring plate 34 turns over the organic fertilizer, and the cold air flow cools the organic fertilizer during the rotation process.

[0048] The implementation principle of the cooling device for organic fertilizer production in the embodiment of the present application is as follows: During use, load the organic fertilizer into the cooling box 1, start the water pump 22 and the cooling fan 32. The water pump 22 pumps the water in the water tank 21 and makes the water flow inside the bottom end and the side wall of the cooling box 1, so that the bottom end and the side wall of the water tank 21 form a water-cooling heat source. The cooling fan 32 blows cold air into the air-cooling pipe 31. The cold air blows out from the first air-blowing holes 311 and the second air-blowing holes 312 to air-cool the organic fertilizer and form an air-cooling heat source in the air-cooling pipe 31. Thus, the organic fertilizer is cooled jointly by the water-cooling heat source, the air-cooling heat source and the blowing cooling, so that the whole organic fertilizer can conduct heat exchange, and further improves the overall cooling effect of the organic fertilizer.

[0049] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
