Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer drying, in particular to a granular water-soluble fertilizer drying machine. Background Art

[0002] Water-soluble fertilizer is a new type of multi-component compound fertilizer. It has significant advantages such as easy solubility, complete nutrients, and fast absorption. It can dissolve quickly in water and provide precise and efficient nutrition supply for crops through irrigation systems or foliar spraying. Whether in greenhouses or large-scale farmland, water-soluble fertilizer is very useful. For example, in vegetable cultivation, it can promote rapid growth of vegetables and improve yield and quality. In the daily production or storage of water-soluble fertilizers, it is necessary to use a water-soluble fertilizer dryer to dry the water-soluble fertilizers.

[0003] A water-soluble fertilizer dryer is an important piece of equipment specifically designed for processing water-soluble fertilizers. Through advanced technology and rational design, it efficiently dries damp water-soluble fertilizers. Its working principle typically utilizes hot air circulation or other drying methods to quickly remove moisture from the fertilizer. This dryer features precise temperature and humidity control, ensuring that the nutrients in the fertilizer are not lost during the drying process. Furthermore, it is easy to operate and has low maintenance costs, providing a strong guarantee for the high-quality production of water-soluble fertilizers.

[0004] When the existing water-soluble fertilizer dryer is drying granular water-soluble fertilizer, the water-soluble fertilizer may stick together during drying, resulting in the water-soluble fertilizer being unable to present a granular form, thereby destroying the shape of the water-soluble fertilizer and affecting subsequent use; and the existing water-soluble fertilizer dryer is unable to distinguish and dry the water-soluble fertilizers separately when drying the same batch of water-soluble fertilizers with different water contents, thereby causing some water-soluble fertilizers with higher water contents to be not dried thoroughly during drying, leading to operational errors. Therefore, a granular water-soluble fertilizer dryer is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the existing equipment, the utility model proposes a granular water-soluble fertilizer dryer.

[0006] The technical solution adopted by the utility model to solve its technical problems is a granular water-soluble fertilizer dryer, comprising a chassis, one side of the chassis is provided with a discharge port; the top of the chassis is provided with a hot air blower; the discharge port is provided with a feed port on the other side corresponding to the hot air blower, the feed port is fixedly connected to a connecting plate, the top of the connecting plate is provided with a No. 1 tray; the bottom of the connecting plate is provided with a No. 2 tray; the bottom of the chassis is provided with a base; the output end of the hot air blower is connected to the fan, and the fan is placed inside the chassis; one side of the No. 1 tray and the No. 2 tray is provided with a screening structure, and the screening structure includes a support plate, eight groups of support columns are fixed inside the support plate, the outside of the support column is slidably connected to the buckle, the bottom of the buckle is welded and connected to a knocking convex plate, and the bottom of the knocking convex plate is provided with a protrusion; thus, the structure transmits heat to the inside of the chassis through the hot air blower model ntfg-x6021b, and dries the water-soluble fertilizer inside the chassis.

[0007] Preferably, an upper conveyor belt is provided on the top of the knocking convex plate, and one hundred to two hundred perforations are opened in the center of the upper conveyor belt; two sets of buckles are provided at the bottom of the upper conveyor belt, and a transmission convex plate is provided on the other side of the knocking convex plate corresponding to the bottom of the upper conveyor belt; a spring is provided on the inner side of the knocking convex plate, and the other side of the spring is welded to the transmission convex plate; a lower conveyor belt is provided between the knocking convex plate and the transmission convex plate, and the end of the lower conveyor belt is connected to the No. 2 tray; the end of the upper conveyor belt is connected to the No. 1 tray; by using a screening structure, water-soluble fertilizers with higher moisture content and water-soluble fertilizers with lower moisture content are distinguished and dried in layers.

[0008] Preferably, four groups of motors are provided inside the support plate, the output ends of the motors are connected to the drive shaft, and six groups of knocking rods are provided outside the drive shaft, and the knocking rods outside the drive shaft are close to the protrusions at the bottom of the knocking convex plate; the connection between the upper conveyor belt and the lower conveyor belt and the knocking convex plate and the transmission convex plate is fixedly connected, and the center parts are not in contact; this structural design can avoid the occurrence of material jamming during the transmission process, thereby increasing the stability and firmness of the device operation.

[0009] The utility model is beneficial in that:

[0010] The utility model adds a screening structure on one side of the dryer. Since the water-soluble fertilizer with a large water content has a large viscosity and thus a large volume, the design screens the water-soluble fertilizer with a small water content and a small volume to the bottom by knocking the lower protrusion to cause the upper conveyor plate to continuously stretch, thereby separating and drying the water-soluble fertilizers separately. As a result, some water-soluble fertilizers with a high water content may not be dried thoroughly during drying, resulting in operational errors. At the same time, the sticky water-soluble fertilizers are vibrated and dispersed by vibrating screening, thereby preventing the water-soluble fertilizers from sticking together during the drying process.

At this time, hot air is generated by the hot air blower 2, and the hot air is conveyed to the surface of the water-soluble fertilizer by the fan 17 to dry the water-soluble fertilizer. At the same time, since the water-soluble fertilizer in the upper layer is in contact with the fan 17 at a closer distance, the temperature of the upper layer will be higher than that of the lower layer. Therefore, the water-soluble fertilizer with higher water content in the upper layer and the water-soluble fertilizer with lower water content in the lower layer can be dried at the same time in almost the same time, and the problem of the water-soluble fertilizer being over-dry due to the original mixed drying can be avoided.

In this way, the knocking convex plate 14 drives the upper buckle 19, thereby causing the upper conveyor belt 13 above the buckle 19 to start stretching and vibrate. At the same time, the transmission convex plate 16 on one side is pulled by the spring 15 to drive the lower conveyor belt 11 at the bottom. At this time, the water-soluble fertilizer with a lower water content will fall along the perforation 12 in the center of the upper conveyor belt 13 to the lower conveyor belt 11 on the lower layer, and through this vibration method, the water-soluble fertilizer will be vibrated and spread on the surface of the conveyor belt. In this way, the water-soluble fertilizer is transported to the feed port 7 on one side of the chassis 1 and transported to the internal tray, and then the drying operation can be carried out.

[0021] Working principle: when screening the water-soluble fertilizer, the operator pours the water-soluble fertilizer onto the surface of the upper conveyor belt 13 and starts the motor 8. At this time, the motor 8 drives the drive shaft 9 to start rotating, and makes the external knocking rod continuously knock the knocking convex plate 14.

At the same time, the transmission convex plate 16 on one side is pulled by the spring 15 to drive the lower conveyor belt 11 at the bottom. At this time, the water-soluble fertilizer with a lower water content will fall along the perforation 12 in the center of the upper conveyor belt 13 to the lower conveyor belt 11 on the lower layer, and through this vibration method, the water-soluble fertilizer will be vibrated and spread on the surface of the conveyor belt. In this way, the water-soluble fertilizer is transported to the feed port 7 on one side of the chassis 1, and transported to the internal tray No. 1 4 and tray No. 2 18. , after which the drying operation can be carried out; when the water-soluble fertilizer is dried, the operator starts the hot air blower 2, and the water-soluble fertilizer is respectively transmitted to the top of the No. 1 tray 4 and the No. 2 tray 18 through the screening structure in the form of the upper layer being the water-soluble fertilizer with high water content and the lower layer being the water-soluble fertilizer with low water content. At this time, hot air is generated by the hot air blower 2, and the hot air is transmitted to the surface of the water-soluble fertilizer through the fan 17 to dry the water-soluble fertilizer. At the same time, since the water-soluble fertilizer in the upper layer is in contact with the fan 17 at a closer distance, the temperature of the upper layer will be higher than that of the lower layer.
