Description

Technical Field

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

[0002] Compound fertilizer is a kind of fertilizer mixed with two or more different ingredients, usually including nitrogen, phosphorus, potassium and other elements, as well as trace elements and other nutrients. Compound fertilizer can provide a variety of nutrients needed for crop growth, which helps to improve crop yield and quality. Compared with single element fertilizers, compound fertilizer can better meet the nutritional needs of crops at different growth stages, reduce the number of fertilization times, and improve fertilization efficiency. In the production process of compound fertilizer, the fertilizer will be made into granules. Granular compound fertilizer is easy to package, transport and store, and is convenient to manage and use. In the production process of compound fertilizer, the granules usually contain a certain amount of water after formation. Drying can help reduce the humidity of the granules and improve the stability and shelf life of the fertilizer.

[0003] The dried compound fertilizer particles will have a certain amount of heat. If they are immediately bagged, sealed or packaged, moisture will condense between the particles, forming lumps and crystals, thus affecting product quality. To avoid this, special cooling equipment is usually used to cool the fertilizer particles to stabilize the particle temperature. However, the common fertilizer cooling equipment usually piles all the particles together for cooling. This method will result in uneven cooling effect and low efficiency. Therefore, a cooling device for compound fertilizer production is proposed to solve the above problems. Utility Model Content

A conveying device 6 is horizontally provided on the inner bottom wall of the frame 1. A heat dissipation mechanism capable of jetting is provided on the rear inner wall of the frame 1.

[0025] In this embodiment, the dried fertilizer particles are placed in the storage frame 2 so that the fertilizer particles are spread out, and the fertilizer particles are pre-cooled by natural heat dissipation. Then, the fertilizer particles are evenly moved from the multiple rectangular frames 3 to the shaking screening mechanism through the material distribution mechanism 4. The fertilizer particles can be quickly dispersed and shaken by the shaking screening mechanism, and the fertilizer particles can be buffered to extend the residence time. Finally, they will fall from the shaking screening mechanism to the conveying device 6 and be transported by it. In this process, the fertilizer particles that fall and stay in the shaking screening mechanism and the conveying device 6 can be sprayed by the heat dissipation mechanism. The generated airflow takes away the hot air, so that the temperature of the composite fertilizer particles gradually decreases. The fertilizer particles are discharged in a dispersed and uniform manner by using multiple rectangular frames 3. At the same time, they are quickly dispersed and shaken by the shaking screening mechanism and the residence time is extended, so that the airflow generated by the heat dissipation mechanism cools the fertilizer particles evenly, and the fertilizer particles will continue to shake and fall, and constantly change positions, thereby accelerating the cooling speed and improving the cooling efficiency.

During this process, the rectangular plate 41 installed on the horizontal shaft 42 and located inside the rectangular frame 3 rotates accordingly, thereby discharging the fertilizer particles in the storage frame 2 from the multiple rectangular frames 3, and then discharging the material in a dispersed and uniform manner. Among them, changing the rotation speed of the motor 43 can change the discharge speed, and a low speed corresponds to slow discharge, and a high speed corresponds to fast discharge.

At the same time, some fertilizer particles will pass through the screen 52 and fall into the belt conveyor to be transported to the left side of the equipment, and the spring 54 can absorb the vibration and impact generated by the operation of the shaking frame 51 and the vibration motor 53, and the fixing frame 55 can be used for the connection between the spring 54 and the frame 1 and the shaking frame 51, and play the role of installation and connection.

The inner rear wall of the frame 1 is provided with a strip box 7 and a jet box 8 in sequence from top to bottom.

The air outlet end of the upper jet hopper 81 faces the top of the screen 52, and the air outlet end of the lower jet hopper 81 faces the top of the conveying equipment 6.

[0032] In this embodiment, the fan 91 generates airflow and transports it to the strip box 1 7 and the air distribution box 82 through the connecting pipe 1 92 and the connecting pipe 2 93. The airflow will be ejected from the spray holes on the strip box 1 7 to cool the fertilizer particles falling from the rectangular frame 3, and the airflow inside the air distribution box 82 will be ejected from the upper and lower jet buckets 81 and the air holes on the strip box 2 83.

[0034] Working principle: The dried fertilizer particles are placed in the storage frame 2 so that the fertilizer particles are spread out, and the fertilizer particles are initially cooled by natural heat dissipation. At the same time, the motor 43 drives the horizontal axis 42 to rotate, and the rectangular plate 41 installed on the horizontal axis 42 rotates accordingly, so that the fertilizer particles in the storage frame 2 are discharged from the multiple rectangular frames 3, and then discharged in a dispersed and uniform manner. At the same time, the vibration motor 53 drives the shaking frame 51 and the screen 52 to vibrate continuously, so that the fertilizer particles falling into the screen 52 are continuously shaken and dispersed, and the retention time of the fertilizer particles is also extended. Then, some fertilizer particles will pass through the screen 52 and fall into the belt conveyor and be transported to the left side of the equipment. In this process, the fan 91 generates airflow and passes through the connecting pipe 9. 2 and connecting pipe 2 93 are transported to strip box 1 7 and air distribution box 82, and the air flow will be sprayed out from the spray holes on strip box 1 7 to cool the fertilizer particles falling from the rectangular frame 3, and the air flow inside the air distribution box 82 will be sprayed out from the upper and lower two jet buckets 81 and the air holes on strip box 2 83, and the air flow sprayed from the air holes will cool the fertilizer particles sieved from the screen 52, and the upper jet bucket 81 will spray toward the screen 52 to cool the fertilizer particles on the screen 52, and the lower jet bucket 81 will spray toward the conveying device 6 to cool the fertilizer particles on the conveying device 6.
