Technical Field

[0001] This utility model relates to the technical field of fertilizer production equipment, and in particular to a drying equipment for the production of organic-inorganic compound fertilizer. Background Technology

[0002] Organic-inorganic compound fertilizer is a new type of fertilizer that combines organic and inorganic fertilizers, offering advantages such as comprehensive nutrient content and long-lasting effects. Drying is a crucial step in the production of organic-inorganic compound fertilizers. Currently, existing drying equipment presents several problems when drying organic-inorganic compound fertilizers. Firstly, uneven distribution of fertilizer within the drying equipment leads to over-drying in some areas and under-drying in others, affecting fertilizer quality and production efficiency. Secondly, traditional drying equipment suffers from high heat energy waste and high energy consumption, increasing production costs. Therefore, there is an urgent need for drying equipment for the production of organic-inorganic compound fertilizers that can solve these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows:

[0005] A drying device for producing organic-inorganic compound fertilizer includes an inclined rotary drum. The high end of the inclined rotary drum is connected to a feed inlet and an air outlet, and the low end of the inclined rotary drum is connected to a discharge outlet and an air inlet. The outer wall of the inclined rotary drum is provided with a heat-insulating jacket, and the inner wall of the inclined rotary drum is provided with an inwardly protruding lifting plate.

[0008] Furthermore, the lower part of the feed inlet passes through the air outlet and is provided with a downward-sloping material channel, and the upper part is connected to an open hopper.

[0009] Furthermore, the air inlet is positioned facing the windward surface of the wind-distributing swing plate.

[0010] Furthermore, the insulation jacket includes two symmetrically arranged arc plates with a cross-section of "(", the top ends of the two arc plates are hinged to the same hanging shaft, a spiral electric heating wire is embedded in the arc plate, the inner wall of the arc plate is not in contact with the inclined rotating cylinder, and an insulation pad is provided on the outer wall.

[0011] Furthermore, the rotating support device includes a vertical support wheel and a horizontal support wheel. Every two horizontal support wheels clamp the wheel ring fixed to the periphery of the inclined rotating cylinder in the middle.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1-7 As shown, a drying device for producing organic-inorganic compound fertilizer includes an inclined rotary drum 1. The high end of the inclined rotary drum 1 is connected to a feed inlet 2 and an air outlet 3, while the low end is connected to a discharge outlet 4 and an air inlet 5. The discharge outlet 4 is located below the air inlet 5, and a uniform air distribution plate 8 is positioned between them. The air inlet 5 faces the windward surface of the uniform air distribution plate 8. A swing shaft 8a is connected to the upper end of the uniform air distribution plate 8, and the swing shaft 8a is driven by a reciprocating swing motor 8b. The lower part of the feed inlet 2 passes through the air outlet 3 and has a downward-sloping material channel 2a, with an open hopper 2b connected to the upper part. The hot air system connected to the air inlet 5 includes a hot air furnace and hot air ducts. The hot air generated by the hot air furnace enters the interior of the inclined rotary drum 1 through the hot air ducts, providing a heat source for the drying process. The setting of the uniform air distribution plate 8 optimizes the distribution of hot air: a gas uniform distribution device, such as the uniform air distribution plate 8, is added at the air inlet 5 to allow hot air to enter the drying tilting drum 1 more evenly, avoiding uneven drying effect caused by excessive or insufficient local airflow.

[0030] The inner wall of the inclined rotary drum 1 is provided with inwardly protruding lifting plates 7. The cross-section of the lifting plates 7 is "U"-shaped, with one end fixed to the inner wall of the inclined rotary drum 1, and the middle notch is uniformly set along the rotation direction of the inclined rotary drum 1. The lifting plates 7 can more frequently and evenly lift and sprinkle the fertilizer inside when the inclined rotary drum 1 rotates, increasing the contact area and opportunity between the fertilizer and hot air, and improving the drying uniformity.

[0031] For details, please refer to [link / reference]. Figure 5The inclined drum 1 is equipped with a rotating support device 9 for support and active rotation. The rotating support device 9 includes a vertical support wheel 9a and a horizontal support wheel 9b. Every two horizontal support wheels 9b clamp the wheel ring 1a fixed to the outer periphery of the inclined drum 1 in the middle. The outer edge of the vertical support wheel 9a abuts against the outer edge of the upper wheel ring 1a. The vertical support wheel 9a is connected to a high-torque low-speed rotary motor 9d through a pulley transmission mechanism 9c. When the rotary motor 9d rotates, it drives the pulley to rotate. The pulley drives part of the vertical support wheel 9a to rotate, and finally drives the wheel ring 1a to rotate synchronously with the inclined drum 1. The fertilizer gradually descends to the discharge port 4 in the rotating inclined drum 1, going against the drying hot air blown from the air inlet 5.

[0032] To reduce heat loss and achieve energy conservation and environmental protection, the outer wall of the inclined drum 1 is equipped with an insulation jacket 6. The insulation jacket 6 includes two symmetrically arranged arc plates 6a with a cross-section of "(". The top ends of the two arc plates 6a are hinged to the same hanging shaft 6b, which is parallel to the central axis of the inclined drum 1, enabling the arc plates 6a to open and close in opposite directions. A coiled electric heating wire 6c is embedded in the arc plate 6a. The inner wall of the arc plate 6a is not in contact with the inclined drum 1, and the outer wall is equipped with an insulation pad 6d. The heating wire 6c can quickly generate heat and uniformly heat the drying drum, ensuring the drying effect. The insulation pad 6d on the outside can reduce heat loss and improve the thermal energy utilization rate. In addition, the inclined drum 1 can also be loaded and unloaded by lifting the insulation jacket 6.

[0033] Meanwhile, support frames 10 are provided below the feed inlet 2, the discharge outlet 4 and the rotating support device 9. The support frames 10 are inclined to achieve the inclined setting of the inclined rotating drum 1, so that the fertilizer can move downward against the drying hot air.

[0034] In the drying process, the fertilizer moves from the higher end to the lower end under the action of gravity by the slow rotation of the inclined drum 1. The inner wall of the inclined drum 1 is equipped with a lifting plate 7 with an opening in the direction of rotation. It continuously lifts up and sprinkles the fertilizer, which greatly enhances the heat contact surface of the fertilizer, prolongs the residence time of the fertilizer particles in the drying drum, and allows the fertilizer particles to be fully heated and dried, thus improving the drying effect.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
