Description

Technical Field

[0001] This utility model relates to the field of fertilizer drying and cooling technology, specifically to a drying and cooling device for manufacturing fertilizers. Background Technology

[0002] In the process of fertilizer production, drying is an extremely important step. If the drying does not meet the requirements, the fertilizer will clump together. Clumping of fertilizer seriously affects its fertility and is not conducive to storage. After drying, fertilizer needs to be cooled down.

[0003] Existing methods typically combine drying and cooling in a rotary drum dryer. However, existing drying and cooling zones have an interface, which causes temperature changes due to the interaction of airflows, affecting the drying and cooling efficiency. Furthermore, the interaction of excess hot and cold air also results in energy waste. Therefore, a drying and cooling device for manufacturing fertilizers is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of drying and cooling devices for manufacturing fertilizers. This utility model provides a drying and cooling device for manufacturing fertilizers.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A drying and cooling device for manufacturing fertilizer includes a drum assembly, a feeding hopper on the side of the drum assembly, a support assembly on the lower side of the drum assembly, a cooling box fixedly installed on the side of the drum assembly, a first connecting pipe on the upper side of the drum assembly, a second connecting pipe fixedly installed on the upper side of the cooling box, flow guiding components mirrored on both sides of the first connecting pipe, and an auxiliary component on the inner side of the first connecting pipe corresponding to the position of the flow guiding components.

[0007] The flow guiding assembly includes a mounting box, inside which a flow guiding shaft is provided, on the side of the flow guiding shaft a motor is provided, and on the side of the mounting box a first flow guiding pipe and a second flow guiding pipe are provided.

[0008] The auxiliary components include a slot, with a one-way plate inside the slot and a deformable plate on the side of the one-way plate.

[0009] Furthermore, the flow guiding assembly includes a mounting box fixedly installed on the side of the first connecting pipe, an inner cavity is opened on the side of the mounting box, the flow guiding shaft is movably installed inside the inner cavity, and a flow guiding cavity is opened on the side of the flow guiding shaft.

[0010] Furthermore, the flow guiding assembly also includes a motor fixedly installed on the side of the mounting box, a first flow guiding pipe fixedly installed on the side of the mounting box, and a second flow guiding pipe fixedly installed on the side of the mounting box.

[0011] Furthermore, the other end of the first guide pipe is fixedly connected to the side of the roller assembly near the cooling box. The first guide pipe passes through the mounting box and the side of the roller assembly to enter the inner cavity and the interior of the roller assembly. The other end of the second guide pipe is fixedly connected to the side of the cooling box. The second guide pipe passes through the mounting box and the side of the cooling box to enter the inner cavity and the interior of the cooling box.

[0012] Furthermore, the auxiliary component includes a slot formed inside the first connecting pipe, a one-way plate fixedly installed on the top wall of the slot, a sealing strip fixedly installed on the bottom side of the one-way plate, and a deformable plate fixedly installed between the side of the one-way plate and the top wall of the slot.

[0013] Furthermore, the slotted section corresponds to the position of the inner cavity through which the first connecting pipe passes. The one-way plate is a rectangular plate made of elastic plastic, the sealing strip is an arc-shaped strip made of soft rubber, and the deformable plate is a rectangular plate made of spring steel with an "S" shaped cross section.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the provision of a flow guiding component, allows the heat flow inside the roller assembly to flow to the cooling area, and then the heat flow can flow back to the first connecting pipe for heat reuse, making full use of the residual heat of the heat flow. The auxiliary component provided can perform unidirectional guidance operation during heat reuse, ensuring that the heat flow in the first connecting pipe does not flow into the inner cavity when the heat flow does not flow back. In addition, when the heat flow inside the roller assembly flows to the cooling area and loses heat, the flow guiding component can guide the heat-lost heat flow to the cooling box, where it works in conjunction with the cold air blown out from the first connecting pipe for cooling. This further utilizes effective energy, avoids energy loss caused by temperature changes due to airflow intersection, and makes full use of excess heat, reducing the energy consumption of the device.

[0026] like Figures 1 to 2As shown, a drying and cooling device for manufacturing fertilizer includes a drum assembly 1, which consists of an outer cylinder and an inner cylinder. A feeding hopper 11 is provided on the side of the drum assembly 1 to convey materials to the inner cylinder of the drum assembly 1. A support assembly 2 is provided on the lower side of the drum assembly 1. The support assembly 2 is a rectangular frame that can fix and support the outer cylinder of the drum assembly 1. A cooling box 3 is fixedly installed on the side of the drum assembly 1. The cooling box 3 is a hollow funnel-shaped box. The materials discharged from the support assembly 2 can fall into the cooling box 3. A first connecting pipe 4 is provided on the upper side of the drum assembly 1. The outer end of the first connecting pipe 4 is connected to a heating fan. The first connecting pipe 4 is a rectangular pipe. A second connecting pipe 5 is fixedly installed on the upper side of the cooling box 3, passing through it. The outer end of the second connecting pipe 5 is connected to a cooling fan. The second connecting pipe 5 is a circular pipe. A flow guiding component 6 is provided on both sides of the first connecting pipe 4 to guide the airflow. An auxiliary component 7 to prevent backflow is provided on the inner side of the first connecting pipe 4 corresponding to the position of the flow guiding component 6.

[0027] Specifically, the material is fed into the drum assembly 1 through the feed hopper 11. The inner cylinder of the drum assembly 1 stirs and guides the material to the cooling box 3. The first connecting pipe 4 enters the hot flow for drying, and the second connecting pipe 5 enters the cold flow for cooling inside the cooling box 3. The set flow guiding component 6 can guide the hot flow entering the first connecting pipe 4 back for reuse. In addition, the set flow guiding component 6 can guide the cold flow that has lost heat to the cooling box 3 to assist in the cooling operation. The set auxiliary component 7 can ensure that the hot flow inside the first connecting pipe 4 will not flow back.

[0028] like Figure 2 As shown in Figure 5, the flow guiding assembly 6 includes a mounting box 61 fixedly installed on the side of the first connecting pipe 4. The mounting box 61 is a rectangular box, and an inner cavity 62 is formed on the side of the mounting box 61 near the first connecting pipe 4. The inner cavity 62 is a cylindrical cavity with a "T"-shaped cross-section. A flow guiding shaft 63 is movably installed inside the inner cavity 62. The flow guiding shaft 63 is a cylindrical shaft. A flow guiding cavity 64 is formed on the side of the flow guiding shaft 63 corresponding to the inner cavity 62. The flow guiding cavity 64 is a "T"-shaped cavity. A motor 65 is fixedly installed on the side of the mounting box 61, and the output end of the motor 65 passes through the mounting box 61 and is fixedly connected to the side of the flow guiding shaft 63. A first guide pipe 66 is fixedly installed on the side of the box 61 away from the first connecting pipe 4, and the other end of the first guide pipe 66 is fixedly connected to the side of the roller assembly 1 near the cooling box 3. The first guide pipe 66 passes through the mounting box 61 and the side of the roller assembly 1 and enters the inner cavity 62 and the interior of the roller assembly 1. A second guide pipe 67 is fixedly installed on the side of the mounting box 61 adjacent to the first connecting pipe 4, and the other end of the second guide pipe 67 is fixedly connected to the side of the cooling box 3. The second guide pipe 67 passes through the mounting box 61 and the side of the cooling box 3 and enters the inner cavity 62 and the interior of the cooling box 3. The first guide pipe 66 and the second guide pipe 67 are circular pipes.

[0029] Specifically, by default, the heat flow from the roller assembly 1 near the cooling box 3 is guided into the guide cavity 64 through the first guide pipe 66, and then discharged into the first connecting pipe 4 through the guide cavity 64. The heat flow is recovered and utilized in conjunction with the first connecting pipe 4. The guide shaft 63 is rotated 90 degrees by the motor 65, and the first guide pipe 66 and the second guide pipe 67 are connected through the guide cavity 64. The first guide pipe 66 carries the heat flow from the roller assembly 1 near the cooling box 3 into the guide cavity 64 and then discharges it into the cooling box 3 through the second guide pipe 67. The material inside the cooling box 3 is cooled in conjunction with the second connecting pipe 5.

[0030] like Figure 4 and Figure 5 As shown, the auxiliary component 7 includes a slot 71 that is inclinedly opened inside the first connecting pipe 4 and the slot 71 passes through the first connecting pipe 4 at the position corresponding to the inner cavity 62. The slot 71 is a rectangular slot. A one-way plate 72 is fixedly installed on the top wall of the slot 71. The one-way plate 72 is a rectangular plate made of elastic plastic. A sealing strip 73 is fixedly installed on the bottom side of the one-way plate 72 and is attached to the bottom wall of the slot 71. The sealing strip 73 is an arc-shaped strip made of soft rubber. A deformable plate 74 is fixedly installed between the side of the one-way plate 72 and the top wall of the slot 71. The deformable plate 74 is a rectangular plate made of spring steel with an "S" shaped cross section.

[0031] Specifically, the deformable plate 74 provides elastic support for the sealing strip 73, allowing the sealing strip 73 to adhere to the bottom wall of the slot 71. The deformable plate 74 closes the slot 71, preventing airflow from the inside of the first connecting pipe 4 into the inner cavity 62. When the inner cavity 62 discharges heat, the heat flows to push the one-way plate 72 to deform, which in turn pushes the deformable plate 74 to deform, allowing the heat to be discharged from the slot 71 into the inside of the first connecting pipe 4 for heat recovery and reuse.

[0032] In summary: the flow guiding component 6 allows the hot flow inside the roller assembly 1 to flow to the cooling area, and then the hot flow can flow back to the first connecting pipe 4 for heat reuse, making full use of the residual heat. The auxiliary component 7 can guide the heat flow in one direction during reuse, ensuring that the hot flow in the first connecting pipe 4 does not flow into the inner cavity 62 when the hot flow does not flow back. In addition, when the hot flow inside the roller assembly 1 flows to the cooling area and loses heat, the flow guiding component 6 can guide the heat-lost hot flow to the cooling box 3, where it works in conjunction with the cold flow blown out from the first connecting pipe 4 for cooling. This further utilizes the effective energy, avoids energy loss caused by temperature changes due to airflow intersection, and makes full use of excess heat, reducing the energy consumption of the device.
