Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a discharging device of a fertilizer drum cooler. Background Art

[0002] Chemical fertilizers, also known as chemical fertilizers, are fertilizers made by chemical or physical methods that contain one or more nutrients required for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc.

[0003] They have the following common characteristics: simple ingredients, high nutrient content, fast fertilizer effect and strong fertilizer effect. Some fertilizers have acid-base reactions and generally do not contain organic matter. There are many types of chemical fertilizers, and their properties and application methods vary greatly.

[0004] After granulation, the fertilizer needs to be sent to the dryer for drying to remove moisture from the fertilizer particles. After drying, the fertilizer cannot be directly bagged due to its high temperature and needs to be cooled. The cooling of fertilizer particles is generally achieved in a drum cooler. During cooling, the fertilizer enters from the feed end of the drum cooler and flows out from the discharge bin at the other end after being processed by the cooling drum.

[0005] Patent document CN 210638416 U discloses a drum cooler discharge device for fertilizer production, comprising a cooling drum, a feed end cap, a discharge mechanism, and a drying device. While this device facilitates drying of compound fertilizer granules discharged from the cooling drum, some of the fertilizer will clump during the cooling process within the drum. Drying during discharge alone is insufficient to break up the clumped fertilizer and can result in the fertilizer being mixed with the normal fertilizer. This not only affects subsequent production processes but also compromises fertilizer production quality. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides a discharging device for a fertilizer drum cooler, such as Figure 1 and Figure 2 As shown, the drum cooler 1 and the discharge bin 2 are sleeved on the discharge end of the drum cooler 1. A connecting hole 201 is provided on one side of the discharge bin 2. The discharge bin 2 is rotatably and sealedly connected to the discharge end of the drum cooler 1 through the connecting hole 201. A ventilation hole 203 is provided on the upper part of the discharge bin 2. A drop opening 202 is provided on the lower part of the discharge bin 2. A discharge pipe 3 is provided at the lower part of the drop opening 202. Both ends of the discharge pipe 3 are open, and the discharge pipe 3 is connected to the interior of the discharge bin 2 through the drop opening 202. Figure 3 and Figure 4 As shown, a filter plate 4 is provided inside the discharge pipe 3 along its length, for filtering the falling fertilizer and retaining the agglomerated fertilizer on the filter plate 4. The inclination direction of the filter plate 4 is the same as that of the discharge pipe 3, and the filter plate 4 divides the inner cavity of the discharge pipe 3 into an upper cavity 301 and a lower cavity 302. A dispersing mechanism 5 is provided above the filter plate 4 on the discharge pipe 3 for dispersing the agglomerated fertilizer.

[0029] like Figure 5 As shown, the crushing mechanism 5 includes a reduction motor 501 and a pressure roller 502. The pressure roller 502 is rotatably connected to the upper cavity 301, and a gap is left between the pressure roller 502 and the upper surface of the filter plate 4. The reduction motor 501 is fixedly installed on the outside of the discharge pipe 3, and the output end of the reduction motor 501 is connected to one end of the pressure roller 502.

[0030] The outer surface of the pressing roller 502 is provided with a plurality of protrusions 5021. The protrusions 5021 are strip-shaped and are divergently arranged along the axis of the pressing roller 502. The strip-shaped protrusions 5021 can increase the roughness of the outer surface of the pressing roller 502, thereby increasing the friction between it and the agglomerated fertilizer.

[0031] Working principle: The fertilizer to be cooled enters the inclined drum cooler 1 through the feed end of the drum cooler 1. After being cooled by the drum cooler 1, the fertilizer will fall into the inside of the discharge bin 2 along the inclined slope, and then directly fall through the drop port 202 to the upper surface of the filter plate 4 in the discharge pipe 3, and slide down along the slope of the filter plate 4. In this process, the unagglomerated fertilizer can pass through the filter holes of the filter plate 4 and fall into the lower cavity 302, and finally flow out through the lower end opening of the discharge pipe 3 and be collected by the external collection device, while the agglomerated fertilizer will also slide along the slope of the filter plate 4 to the pressing roller 502. The pressing roller 502 is driven by the reduction motor 501 along the Figure 4 The filter plate 4 and the pressing roller 502 rotate slowly in the direction indicated by the arrow in the figure. During this process, the agglomerated fertilizer can be squeezed out by cooperating with the filter plate 4, thereby breaking up the agglomerated fertilizer. In the process of squeezing the agglomerated fertilizer, the protrusion 5021 can assist in the material transfer, and promote the agglomerated fertilizer to enter the gap between the filter plate 4 and the pressing roller 502, thereby ensuring the smooth progress of the breaking up work. The broken up fertilizer will continue to slide down the slope of the filter plate 4, and will eventually flow out through the lower end opening of the discharge pipe 3 and be collected by an external collecting device. Therefore, in the process of unloading after cooling, the agglomerated fertilizer can be filtered, intercepted and broken up, thereby preventing the agglomerated fertilizer from being mixed into normal fertilizer, thereby ensuring the production quality of the fertilizer.

[0032] like Figure 3 and Figure 4 As shown, a material-dividing assembly 7 is provided on the discharge pipe 3 above the filter plate 4. The material-dividing assembly 7 is located on the upper side of the crushing mechanism 5. A reciprocating mechanism 6 is provided between the material-dividing assembly 7 and the crushing mechanism 5. The crushing mechanism 5 can drive the material-dividing assembly 7 to slide back and forth on the upper surface of the filter plate 4 through the reciprocating mechanism 6.

[0033] The reciprocating mechanism 6 includes a rotating disk 601, a connecting rod 602 and a sliding frame 603. The rotating disk 601 is fixedly connected to the end of the pressure roller 502 away from the reduction motor 501. The sliding frame 603 is fixedly connected to the upper part of the material digging assembly 7. One end of the connecting rod 602 is rotatably connected to the rotating disk 601 through a rotating shaft, and the other end is rotatably connected to the sliding frame 603 through a rotating shaft. The sliding frame 603 is slidably connected to the discharge pipe 3 along the length direction.

[0034] A rectangular chute 303 is formed along the length of the upper portion of the discharge pipe 3. A sliding frame 603 is slidably connected to the interior of the chute 303. A connecting groove 6031 is formed on the exterior of the sliding frame 603. The sidewalls of the chute 303 are inserted and slidably connected to the interior of the connecting groove 6031.

[0035] like Figure 6As shown, the material shifting assembly 7 is parallel to the filter plate 4, and the material shifting assembly 7 includes a sliding rod 701 and a plurality of shifting rods 702. The sliding rod 701 abuts against the upper surface of the filter plate 4 along the length direction of the filter plate 4, and the shifting rod 702 is fixedly connected to the outside of the sliding rod 701. The shifting rod 702 abuts against the upper surface of the filter plate 4, and the plurality of shifting rods 702 are equidistantly distributed along the length direction of the sliding rod 701.

[0036] Working principle: During the slow rotation of the pressure roller 502, the rotating disk 601 is also driven to rotate synchronously. The rotating disk 601 then pushes or pulls the sliding frame 603 through the connecting rod 602, thereby driving the sliding frame 603 to slide back and forth along the slide groove 303. The sliding frame 603 can also drive the sliding rod 701 and the dial rod 702 to slide back and forth synchronously on the upper surface of the filter plate 4. In this process, the reciprocating movement of the dial rod 702 can have a certain dispersing effect on the fertilizer, which can prevent the fertilizer falling on the upper surface of the filter plate 4 from piling up, and can also squeeze the fertilizer particles blocked in the filter holes of the filter plate 4 by sliding, so as to assist the fertilizer particles to pass through the filter plate 4 smoothly and prevent the fertilizer from clogging the filter plate 4.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
