Description

Technical Field

[0001] This utility model relates to the production of compound fertilizers, and more specifically, to a dryer for the production of compound fertilizers. Background Technology

[0002] In the production of compound fertilizers, raw materials or semi-finished products after granulation usually contain a certain amount of moisture. Excessive moisture can affect the quality and storage stability of compound fertilizers. Rotary drum dryers can remove moisture from materials by evaporating it with hot air through heat exchange, reducing the moisture content of compound fertilizers to levels that meet national standards and industry requirements. This ensures that the product does not clump or deteriorate during storage and transportation. During operation, wet materials enter the rotary drum dryer from the feeding device. As the drum rotates at a certain angle and speed, the material is continuously lifted and scattered by the lifting plates, forming a uniform material curtain inside the drum. At the same time, the hot air generated by the hot air furnace... Air enters from the other end of the cylinder, forming counter-current or co-current contact with the material. During the full contact between the hot air and the material, heat is transferred to the material through conduction, convection, and radiation, causing the moisture in the material to evaporate rapidly into water vapor. Due to the certain inclination of the cylinder, the material moves slowly from the high end to the low end under the combined action of gravity and cylinder rotation. During the movement, it continuously exchanges heat with the hot air for further drying. Finally, the dried material is discharged from the discharge device. Since the material inside the dryer is turned over, it directly affects the drying time and drying effect after the material enters. Therefore, it is necessary to process the material into powder.

[0003] In related technologies, during the use of a dryer, material lifting plates are generally installed on the inner wall of the drying drum to rotate and disperse the material entering the drying drum, so that the material is evenly dispersed after entering the drying drum for use.

[0004] However, in the current use of dryers, the material lifting plates that are directly installed on the inner wall of the drying drum are generally simple protruding plates. The design of the material lifting plates is not reasonable, and the tilting angle is insufficient. After the material enters, it can only drive the material to tilt at a small angle, resulting in incomplete material tilting inside the drying drum, unstable drying time and uneven drying, which affects the uniformity and stability of the drying of compound fertilizer materials by the dryer.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a dryer for compound fertilizer production, including a drying drum 1 and a drive feeding mechanism. An organic head feed box 2 is installed on the left side of the drying drum 1, and a tail box 3 is installed on the right side of the drying drum 1. The tail box 3 can provide a drive source for the rotation of the drying drum 1, and when the drying drum 1 rotates, it performs a large-angle turning operation on the material inside the drying drum 1, so that the material inside the drying drum 1 is evenly turned and dispersed. This avoids the situation where the turning angle is insufficient during the drying of the material inside the drying drum 1, resulting in uneven material dispersion and different drying times and degrees. Therefore, it improves the uniformity and stability of the turning and drying of the drying drum 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the driving material-lifting mechanism includes a transmission gear set 4, which is mounted on the surface of the drying drum 1.

A reducer 6 is driven and connected to the left side of the transmission gear seat 5. A motor 7 is driven and connected to the left side of the reducer 6. Lifting plates 18 are mounted on the inner wall of the drying drum 1. Since the lifting plates 18 have a double helix structure and each lifting plate 18 is J-shaped, when the material enters the drying drum 1, the lifting plates 18 can drive the material entering the drying drum 1 to perform large-angle turning and dispersing work, so that the drying drum 1 can evenly disperse and dry the compound fertilizer material inside. Tires 8 are mounted on both sides of the surface of the drying drum 1, and roller sets 9 that contact the tires 8 are mounted on both sides of the bottom of the drying drum 1. These roller sets 9 can rotate and support the drying drum 1 during operation, avoiding the situation where the drying drum 1 is difficult to support during operation, thus improving the convenience of supporting the drying drum 1.

[0032] Reference Figures 2-4In a preferred embodiment, a feed inlet 10 is installed on the top of the feed box 2 at the machine head. The bottom of the feed inlet 10 is inclined and connected to the drying drum 1. This provides a medium for adding compound fertilizer material into the drying drum 1 during operation and guides the added compound fertilizer material, thus avoiding the inconvenience of feeding the drying drum 1 and improving the feeding convenience of the drying drum 1. An air inlet 11 is provided on the left side of the feed box 2 at the machine head. The air inlet 11 is connected to the drying drum 1 through the feed box 2 at the machine head. This provides a medium for connecting the drying drum 1 to the external hot air supply system, allowing the operator to connect the drying drum 1 to the external hot air supply system and avoiding the inconvenience of connecting the drying drum 1 to the external hot air supply system during operation. This further improves the convenience of connecting the drying drum 1 to the external hot air supply system.

[0033] Reference Figures 2-4 In a preferred embodiment, a cleaning port 12 is provided at the bottom of the feed box 2, and a cleaning plate 13 is installed at the bottom of the cleaning port 12. This provides workers with a space to regularly inspect and clean the inside of the feed box 2, so that workers can discharge the dirt after cleaning the inside of the feed box 2. This avoids the situation where the dirt is difficult to discharge when the feed box 2 is in use, thus improving the convenience of cleaning and draining the feed box 2. An exhaust outlet 14 is provided at the top of the tail box 3. The exhaust outlet 14 is connected to the drying drum 1 through the tail box 3. The tail box 3 provides space for the drying drum 1 to discharge hot exhaust gas, and also allows workers to connect the drying drum 1 to the external exhaust pipe. This avoids the situation where the hot exhaust gas is difficult to connect to the external pipe and discharge when the drying drum 1 is in use, thus improving the convenience of connecting and discharging the hot exhaust gas of the drying drum 1.

[0034] Reference Figures 2-4 In a preferred embodiment, maintenance ports 15 are provided at the bottom of both the tail box 3 and the head feed box 2, and maintenance plates 16 are installed on the outside of the maintenance ports 15. This provides operators with operating space for regular inspection and maintenance of the head feed box 2 and the tail box 3, avoiding the difficulty in inspecting and maintaining the internal condition of the head feed box 2 and the tail box 3 during use. Therefore, the convenience of inspection and maintenance of the head feed box 2 and the tail box 3 is improved. The bottom of the tail box 3 is provided with a discharge port 17, which is connected to the drying drum 1 through the tail box 3. The tail box 3 can provide space and medium for the drying drum 1 to be connected to the external discharge pipeline, so that operators can perform discharge connection operations on the drying drum 1 according to the actual situation. Therefore, the convenience of discharge operation of the drying drum 1 is improved.

[0035] Specifically, the working process or principle of this dryer for compound fertilizer production is as follows: During use, a suitable installation location is selected within the compound fertilizer production workshop, ensuring the foundation for installing the drying drum 1 is secure. Then, the drying drum 1 is connected to the external hot air supply system via the air inlet 11 and the feed box 2 at the machine head. The external exhaust pipe is connected to the drying drum 1 via the tail box 3 and the exhaust outlet 14, preparing for the subsequent supply and discharge of hot air for drying the drum 1. It is important to ensure that the installation connections are secure during installation. According to the actual production and processing needs of compound fertilizer, the drying drum 1 is connected to the external discharge pipeline through the discharge port and the tail box 3, and the external feeding equipment is located at the top of the inlet 10 to prepare for the subsequent drying feeding and discharging of the drying drum 1. The motor 7 is a variable frequency motor, which can flexibly adjust the speed of the drying drum 1 according to the characteristics of the material and the drying requirements to ensure that the residence time of the material in the drying drum 1 is appropriate. When the motor 7 is powered on, it drives the drying drum 1 to work through the transmission gear set 4 and the transmission gear seat 5. The lifting plate 18 moves with the drying drum 1. As the compound fertilizer material from the outside enters the drying drum 1 through the feed box 2 and feed inlet 10, the lifting plates 18, which have a double-helix structure and are individually J-shaped, come into contact with the compound fertilizer material inside the drying drum 1. The lifting plates 18 then drive the compound fertilizer material to rotate with the drying drum 1. As the drying drum 1 rotates, the position of the lifting plates 18 changes, causing the compound fertilizer material to move to a higher position. When the lifting plates 18 move downwards, the compound fertilizer material driven by the lifting plates 18 is further moved by the drying drum. The position and angle after the movement affect the material's movement. The material moves downward and disperses to the bottom of the inner wall of the drying drum 1. This process is repeated to turn and disperse the compound fertilizer material inside the drying drum 1 at a large angle, so that the drying drum 1 can evenly turn and dry the compound fertilizer material inside. This ensures that the compound fertilizer material can fully contact the hot air during the drying process and ensures the uniformity of drying. During this process, the inner spiral blades are used to push the material forward and push the dried compound fertilizer material towards the tail box 3 so that the dried compound fertilizer material can be discharged through the tail box 3 and the discharge port 17.

[0036] It should be noted that the drying drum 1, the head feed box 2, the tail box 3, the transmission gear set 4, the gear seat 5, the reducer 6, the motor 7, the tire 8, and the towing wheel set 9 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail.
