Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production equipment, in particular to a novel cooling device for compound fertilizer production. Background Art

[0002] Compound fertilizer is a kind of chemical fertilizer containing two or more nutrient elements, which has the advantages of high nutrient content, few secondary components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops. There are many types of compound fertilizers, which can be divided into chemical compound fertilizers and mixed compound fertilizers according to the manufacturing method, binary compound fertilizers, ternary compound fertilizers and multi-element compound fertilizers according to the contained nutrients, and high, medium and low series compound fertilizers according to the concentration content.

[0003] However, most of the traditional cooling devices for compound fertilizer production adopt two old cooling drums. The high-temperature compound fertilizer is flipped in one old cooling drum, and the outside cool air is sucked by a suction fan for heat dissipation and cooling, and then transported to another old cooling drum for the same operation of cooling. The efficiency of this cooling method is relatively low, and it can only rely on the weather temperature for heat dissipation, resulting in the inability to accurately control the temperature inside the device. Moreover, due to the frequent collisions of the finished product particles in the cooling drum of the old cooling drum cooling device, the originally round and uniform product particles collide and break, affecting the appearance of the product.

[0004] Therefore, the technical personnel in this field provide a novel cooling device for compound fertilizer production to solve the problems raised in the above background art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a novel cooling device for compound fertilizer production is proposed. The cooling device for compound fertilizer production is provided with ventilation grooves in the main body. Under the action of a suction fan, external air flows into the ventilation grooves, and then contacts with the second baffle on the first heat conducting block. Under the action of the low-temperature liquid in the second water storage tank and the second conveying pipeline, the air flow in the ventilation grooves is reduced to the required range, so that the device can process the external air flow into low-temperature air flow and blow it to the compound fertilizer particles in the main body that need heat dissipation and cooling, and flow out together with the particles. Furthermore, the low-temperature air flow can contact the particles more comprehensively, further reducing the temperature of the inside of the main body and the second heat conducting plate, improving the cooling efficiency of the device. Moreover, under the action of the first baffle and the second baffle, the flowing distance of the air flow in the ventilation grooves is increased, and the contact area between the air flow and the first heat conducting plate is also increased, so that the cooling efficiency of the device for the air flow is improved, and further energy waste is reduced.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Refer to Figure 1-8 , an embodiment provided by the present invention:

[0041] A new type of cooling equipment for compound fertilizer production includes a base 1. A plurality of support legs 2 are fixedly connected to the upper surface of the base 1. A workbench 7 is fixedly connected to the upper surface of the support legs 2. A Roots heating blower 47 is fixedly connected to the middle of the lower surface of the workbench 7. A controller 8 is fixedly connected to the middle of one side of the upper surface of the workbench 7. A main body 14 is fixedly connected to the middle of the upper surface of the workbench 7. The upper part of the front outer wall of the main body 14 is fixedly connected to a delivery channel 13. The upper end of one side outer wall of the main body 14 is fixedly connected to a third servo motor 15. The output end of the third servo motor 15 is fixedly connected to a rotating rod 16. The middle of the outer wall of the rotating rod 16 is fixedly connected to a height limit roller 17. The lower part of the front outer wall of the main body 14 is fixedly connected to a first water storage tank 18.

[0042] On one side of the inner bottom surface of the first water storage tank 18, a first conveying block 24 is fixedly connected. In the middle of the upper surface of the first conveying block 24, a first drain pipe 30 is fixedly connected. A chamber 25 is provided inside the first conveying block 24. In the middle of the inner bottom surface of the chamber 25, a pump body 26 is fixedly connected. In the middle of the outer wall at the rear end of the main body 14, a second water storage tank 31 is fixedly connected. At the lower part of the front inner wall of the second water storage tank 31, a second drain pipe 35 is fixedly connected. At the rear end inside the main body 14, a second conveying pipe 36 is fixedly connected. At the lower part of the outer wall at the rear end of the main body 14, a protective shell 37 is fixedly connected. At the rear end of the inner wall of the protective shell 37, a first filter screen 38 is fixedly connected. At the front end of the inner wall of the protective shell 37, an air suction fan 39 is fixedly connected. Inside the main body 14, a ventilation groove 40 is fixedly connected. At the upper end of the inner wall of the ventilation groove 40, a second filter screen 44 is fixedly connected.

[0043] On the inner wall at the front end of the ventilation groove 40, a plurality of first baffles 41 are fixedly connected. On the inner wall at the rear end of the ventilation groove 40, a first heat conducting plate 42 is fixedly connected. On the outer wall at the front end of the first heat conducting plate 42, a plurality of second baffles 43 are fixedly connected. On the inner walls at the front and rear ends of the main body 14, a plurality of guiding inclined plates 45 are fixedly connected. On the upper surface of the guiding inclined plates 45, a second heat conducting plate 46 is fixedly connected. Inside the guiding inclined plates 45, a first conveying pipe 29 is fixedly connected.

[0044] The cooling equipment for compound fertilizer production cancels the old-fashioned cooling drum. A plurality of guiding inclined plates 45 are arranged inside the main body 14. The height-limiting roller 17 is used to limit the number of compound fertilizer particles to be cooled entering the guiding inclined plates 45, reducing the possibility that the compound fertilizer particles accumulate and affect the cooling, so that the compound fertilizer particles can be more dispersed in contact with the second heat conducting plate 46 on the guiding inclined plates 45. Thus, the heat of the compound fertilizer particles can be absorbed by the second heat conducting plate 46. Then, through the pump body 26, the low-temperature liquid in the first water storage tank 18 can flow in the first conveying pipe 29, so as to absorb the heat on the second heat conducting plate 46. Furthermore, the second heat conducting plate 46 can always be kept at a lower temperature, enabling the equipment to more effectively and quickly dissipate the heat of the compound fertilizer particles. The one-way flow heat dissipation method reduces the collision between the compound fertilizer particles, thereby improving the aesthetics and roundness of the produced compound fertilizer particles. And the user can accurately adjust the temperature of the liquid in the first water storage tank 18 through the controller 8, so as to adjust the temperature inside the main body 14, and then control the temperature of the finished product particles and more accurately control the temperature of the finished product coating.

[0045] A first servo motor 3 is fixedly connected to the upper end of the outer wall on one side of the support leg 2. A limiting partition 4 is fixedly connected to the inner wall of the support leg 2. A conveyor belt 5 is fixedly connected to the inner wall of the limiting partition 4. By providing the limiting partition 4 and the conveyor belt 5, the processed compound fertilizer particles can be conveyed into the coating drum for the next layer of processing. A fixing ring 9 is fixedly connected to the middle of the front outer wall of the workbench 7. A housing 10 is fixedly connected to the inner wall of the fixing ring 9. A placement box 6 is fixedly connected to the front end of the upper surface of the base 1, so that the compound fertilizer particles in the placement box 6 can be conveyed into the housing 10 and then into the main body 14. A second servo motor 11 is fixedly connected to the middle of the upper surface of the housing 10. A screw blade 12 is fixedly connected to the output end of the second servo motor 11, so that the second servo motor 11 can control the screw blade 12 to convey the compound fertilizer particles. A first liquid changing port 19 is fixedly connected to one side of the upper surface of the first water storage tank 18. A protective cover 20 is in threaded cooperation with the upper end of the outer wall of the first liquid changing port 19. A second liquid changing port 32 is fixedly connected to one side of the upper surface of the second water storage tank 31, so that the user can supplement the liquid in the first water storage tank 18 and the second water storage tank 31 by rotating the protective cover 20.

[0046] A water suction pipe 27 is fixedly connected to the water inlet of the pump body 26. A water inlet pipe 28 is fixedly connected to the water outlet of the pump body 26. By providing the water suction pipe 27 and the water inlet pipe 28, the pump body 26 can convey the low-temperature liquid in the first water storage tank 18 into the first conveying pipeline 29. First placement grooves 21 are formed in the outer walls on both sides of the first water storage tank 18. A refrigerating sheet 22 is fixedly connected to the side of the inner wall of the first placement groove 21 close to the first water storage tank 18. A heat dissipation plate 23 is fixedly connected to the side of the inner wall of the first placement groove 21 far from the first water storage tank 18. By providing the refrigerating sheet 22, the liquid in the first water storage tank 18 is cooled. A second conveying block 34 is fixedly connected to one side of the inner bottom surface of the second water storage tank 31. A second placement groove 33 is formed in the outer wall at the rear end of the second water storage tank 31. The structure of the second water storage tank 31 is similar to that of the first water storage tank 18, both are provided with a pump body 26 and a refrigerating sheet 22, so that the low-temperature liquid in the second water storage tank 31 can be conveyed into the second conveying pipeline 36.

[0047] Working principle: First, the produced compound fertilizer particles are introduced into the placement box 6 through the conveying device, and are conveyed into the conveying channel 13 under the action of the elevator composed of the housing 10, the second servo motor 11 and the auger blades 12. Then, the number of particles flowing at one time is restricted by the height-limiting roller 17, so that the particles can come into contact with the second heat-conducting plate 46 more comprehensively under the action of gravity, and thus are cooled by the low-temperature second heat-conducting plate 46. The pump body 26 in the first water storage tank 18 conveys the low-temperature liquid into the first conveying pipeline 29, so as to absorb heat and cool the second heat-conducting plate 46 with increased temperature, and further enable the temperature of the second heat-conducting plate 46 to always be maintained within the required range. Then, the suction fan 39 sucks the external air flow into the ventilation groove 40, and after being cooled by the first heat-conducting plate 42 in the ventilation groove 40, it is discharged into the main body 14 and comes into contact with the high-temperature particles more comprehensively. The increase in the temperature of the first heat-conducting plate 42 will be absorbed by the low-temperature liquid in the second water storage tank 31, so that the temperature of the first heat-conducting plate 42 is always maintained within a suitable range. The gas is discharged from the main body 14 together with the particles. Because the low temperature is neutralized by the high-temperature particles, the temperature of the discharged air flow is not low. Then, after being heated by the Roots heating fan 47, the particles are dried to reduce the generation of moisture.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
