Technical Field

[0001] This utility model relates to the field of material production equipment technology, specifically to an anti-caking agent addition device. Background Technology

[0002] Diammonium phosphate is easily affected by external conditions such as temperature, humidity, and compressive strength. During loading, unloading, storage, and transportation, it can easily become hard and difficult-to-break lumps due to moisture absorption and surface recrystallization. This causes inconvenience to the storage, transportation, and especially the use of diammonium phosphate, and can even cause significant economic losses. To prevent diammonium phosphate from clumping, coating equipment is usually used to coat the surface of diammonium phosphate granules with an anti-caking agent to form a protective film and prevent the fertilizer granules from absorbing moisture.

The screening mechanism includes a screen connected to the end of the drum, a discharge port A located at the bottom of the screen, and a discharge port B located on the side of the screen. A shovel plate is also provided on the inner side of the drum.

[0004] In the aforementioned prior art, the rollers are horizontally positioned, which is not conducive to discharging the diammonium phosphate that has been wrapped inside the rollers, thus affecting production efficiency. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] To address the technical problem of existing technologies hindering the discharge of diammonium phosphate particles from the drum, thus affecting production efficiency, this invention provides an anti-caking agent addition device that can quickly discharge diammonium phosphate particles, thereby improving production efficiency.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the anti-caking agent adding device in one embodiment of the present invention.

[0034] This utility model provides an anti-caking agent adding device, including a base 1, a rotating assembly 2, a driving mechanism 3, and an anti-caking agent atomizing assembly 4; the rotating assembly 2 is rotatably mounted on the base 1 along a horizontal axis, and the rotating assembly 2 has a rotating part that rotates along its axis, the rotating part being used to accommodate material; the driving mechanism 3 is connected to the rotating assembly 2, and the driving mechanism 3 is used to drive the rotating assembly 2 to rotate so that when discharging material, the rotating part tilts downward along the material flow direction; the anti-caking agent atomizing assembly 4 is disposed on the base 1 and a portion of it extends into the rotating part for spraying anti-caking agent into the rotating part.

[0035] In this embodiment, please refer to Figures 1 to 3The rotating assembly 2 is rotatably mounted on the base 1. The driving mechanism 3 is connected to the rotating assembly 2 and can drive the rotating assembly 2 to rotate around its rotation point, thereby adjusting the position of the rotating assembly 2. In specific use, the driving mechanism 3 drives the rotating assembly 2 to rotate, making the rotating part horizontal. Then, the diammonium phosphate semi-finished product particles are conveyed into the rotating part. Through the rotation of the rotating part, the diammonium phosphate semi-finished product particles continuously tumble inside. Then, the anti-caking agent atomizing assembly 4 sprays anti-caking agent into the rotating part, so that the anti-caking agent is evenly attached to the surface of the semi-finished product particles, forming a protective layer, thereby playing a role in preventing agglomeration. After the wrapping operation is completed, the driving mechanism 3 drives the rotating assembly 2 to rotate, making the rotating part tilt downward along the material flow direction. At this time, the diammonium phosphate particles move quickly towards the discharge end of the rotating part under their own gravity, thereby achieving the purpose of quickly discharging the diammonium phosphate particles and improving production efficiency.

[0036] In this embodiment, the anti-caking agent is an oil-based anti-caking agent. Oil-based anti-caking agents are typically composed of a surfactant and a base oil. They primarily utilize the special hydrophilic and lipophilic structure of the surfactant to establish a hydrophobic film on the particle surface. By reducing the interfacial tension and contact angle between the solid and liquid phases, they improve the crystallization habit of diammonium phosphate, interfere with intermolecular forces within the crystal, and alter the crystal form of diammonium phosphate. This weakens the crystallization strength and binding force, reduces the surface energy of the crystal, and thus significantly reduces the product's hygroscopicity, achieving the purpose of preventing caking. Taking a commonly used surfactant—fatty amines—as an example, it is an effective anti-caking agent component. Under certain conditions, the R(CH2) of fatty amines... n NH3 + NH4 in the structure of cations and compound fertilizer complex salts + Mg 2+ Ion exchange occurs, causing changes in the crystal properties. Crystals without anti-caking agents have a rod-like structure and are prone to sticking together and bridging to form hard lumps. However, when fatty amines are added, the crystals become villous, and the crystal bridges become fragile and break apart easily, thus providing a good anti-caking effect.

[0037] In practice, the application of anti-caking agents in the production of diammonium phosphate yielded significant anti-caking effects. Even when stacked 18 layers high, diammonium phosphate remained free of caking for 60 days. Control experiments on factors such as the neutralization degree of the semi-finished product, temperature, moisture content, and particle size showed that the anti-caking agent achieved the best coating effect when the neutralization degree of the semi-finished product was in the range of 1.78–1.82, the temperature of the semi-finished product was below 45°C, the moisture content of the finished product was below 2.0%, and the pass rate for particle size (2–4 mm) reached over 95%.

[0038] In this embodiment, please refer to Figure 3One end of the rotary assembly 2 is rotatably mounted on the base 1 along the horizontal axis, and the drive mechanism 3 is connected to the other end of the rotary assembly 2.

[0039] Specifically, the rotary assembly 2 has a first end and a second end that are arranged opposite to each other along the material flow direction. The first end is rotatably mounted on the base 1 along a horizontal axis. The drive mechanism 3 is connected to the second end, thereby driving the second end to rotate around the axis at the first end. When material needs to be discharged, the drive mechanism 3 drives the second end to rotate downward, so that the second end is lower than the first end, thereby achieving the downward tilting of the rotary part along the material flow direction. Alternatively, the second end is rotatably mounted on the base 1 along a horizontal axis. The drive mechanism 3 is connected to the first end, thereby driving the first end to rotate around the axis at the second end. When material needs to be discharged, the drive mechanism 3 drives the first end to rotate upward, so that the first end is higher than the second end, thereby achieving the downward tilting of the rotary part along the material flow direction.

[0040] In another embodiment, the central part of the rotary assembly 2 is rotatably mounted on the base 1 along a horizontal axis, and the drive mechanism 3 is connected to one end of the rotary assembly 2.

[0041] Specifically, the slewing assembly 2 is rotatably mounted on the base 1. When the driving mechanism 3 is connected to the first end, it drives the first end to move upward. When the driving mechanism 3 is connected to the second end, it drives the second end to move downward.

[0042] In this embodiment, please refer to Figures 2 to 4 The rotating assembly 2 includes a mounting base 21, a rotating cylinder 22, and a drive assembly 23. The mounting base 21 is rotatably mounted on the base 1 and is connected to the drive mechanism 3. The rotating cylinder 22 is rotatably mounted on the mounting base 21 along its own axis and constitutes the rotating part. The drive assembly 23 is disposed on the mounting base 21 and is connected to the rotating cylinder 22 to drive the rotating cylinder 22 to rotate.

[0043] Specifically, the first end of the mounting base 21 is rotatably mounted on the base 1, and the mounting base 21 and the base 1 are spaced apart. The rotary drum 22 is rotatably mounted on the mounting base 21. The driving assembly 23 can drive the rotary drum 22 to rotate relative to the mounting base 21, ensuring that the material continuously tumbles inside the rotary drum 22. The driving mechanism 3 is located between the mounting base 21 and the base 1 and is connected to the mounting base 21. The driving mechanism 3 can drive the mounting base 21 and the rotary drum 22 to rotate around the first end, thereby adjusting the tilt of the rotary drum 22.

[0044] Specifically, the drive assembly 23 includes a gear ring 231, a gear 232, and a drive motor 233. The gear ring 231 is disposed on the outer periphery of the rotary drum 22. The gear 232 is rotatably mounted on the mounting base 21 and meshes with the gear ring 231. The main shaft of the drive motor 233 is connected to the gear 232.

[0045] In this embodiment, please refer to Figure 4 The rotary assembly 2 also includes a plurality of first lifting plates 24, which are spaced apart circumferentially within the rotary drum 22, and the height of the first lifting plates 24 gradually decreases in the material flow direction.

[0046] Specifically, the first lifting plate 24 extends along the radial direction of the rotary drum 22 and is installed on the inner side wall of the rotary drum 22. By setting the first lifting plate 24, material particles can be dispersed and the coating effect can be improved.

[0047] Furthermore, the rotary assembly 2 also includes a plurality of second lifting plates 25, which are spaced apart circumferentially within the rotary drum 22. The first lifting plate 24 and the second lifting plates 25 are arranged sequentially along the material flow direction, and the second lifting plates 25 are inclined along the material flow direction. The second lifting plates 25 are located at the discharge end of the rotary drum 22, and the inclined arrangement of the second lifting plates 25 can accelerate the discharge of material from the rotary drum 22.

[0048] In this embodiment, the rotary assembly 2 further includes a first retaining ring 26 and a second retaining ring 27. The first retaining ring 26 is disposed at the feed end of the rotary drum 22, and the second retaining ring 27 is disposed at the discharge end of the rotary drum 22.

[0049] Specifically, during the packaging process, in order to prevent material from leaking from both ends of the rotary drum 22, retaining rings are installed at both ends of the rotary drum 22, thereby sealing both ends of the rotary drum 22 to a certain extent and preventing material leakage.

[0050] In this embodiment, the second retaining ring 27 is movably disposed along the discharge end of the rotary drum 22, both near and far from it.

[0051] Specifically, to avoid interference with material discharge during discharge, the second baffle ring 27 is movably mounted on the mounting base 21 along the discharge end of the rotary drum 22, both near and away from it. This allows it to have a blocking state where it moves towards the discharge end of the rotary drum 22 and abuts against it, and a discharge state where it moves away from the discharge end of the rotary drum 22 and is spaced apart from it. In practical use, when in the wrapping operation, the second baffle ring 27 moves to the blocking state to prevent material leakage. When in the discharging state, the second baffle ring 27 moves to the discharge state to avoid interference with material discharge.

[0052] Furthermore, the rotary assembly 2 also includes a drive cylinder 28, which is provided with the mounting base 21. The push rod of the drive cylinder 28 is connected to the second retaining ring 27 to drive the second retaining ring 27 to move.

[0053] In this embodiment, the driving mechanism 3 includes a connecting seat 31, a connecting member 32, and a driver 33. The connecting seat 31 is movably mounted on the base 1 along the axial direction of the rotary assembly 2. The two ends of the connecting member 32 are rotatably connected to the connecting seat 31 and the rotary assembly 2, respectively. The driver 33 is connected to the connecting seat 31 to drive the connecting seat 31 to move.

[0054] Specifically, the two ends of the connector 32 are rotatably connected to the connector 31 and the mounting base 21, respectively. When the connector 31 drives the connector 32 to move to an inclined state, the rotary drum 22 is in an inclined state. When the connector 31 drives the connector 32 to move to a vertical state, the rotary drum 22 is in a horizontal state.

[0055] Furthermore, the specific form of the actuator 33 is not limited; the actuator 33 can be one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0056] In this embodiment, the rotary section has a feed end and a discharge end that are arranged opposite to each other along the material flow direction; the anti-caking agent adding device further includes a first conveyor belt 5 and a second conveyor belt 6, the first conveyor belt 5 being connected to the feed end for conveying material to the rotary section, and the second conveyor belt 6 being connected to the discharge end for sending the material out of the rotary section.

[0057] Specifically, the first conveyor belt 5, the rotary assembly 2, and the second conveyor belt 6 are sequentially connected along the material flow direction, and the first conveyor belt 5 and the second conveyor belt 6 are arranged to facilitate the material transport.

[0058] In this embodiment, the first conveyor belt 5 is a metering conveyor belt.

[0059] Specifically, the amount of diammonium phosphate that enters the rotary drum 22 after accurate measurement is achieved. The first conveyor belt 5 is a metering conveyor belt, so that the set amount of diammonium phosphate can be conveyed into the rotary drum 22.

[0060] In this embodiment, the anti-caking agent atomizing component 4 includes an oil storage tank 41, an oil pump 42, a delivery pipe 43, and a plurality of atomizing nozzles 44. One end of the delivery pipe 43 is connected to the oil storage tank 41 through the oil pump 42. The delivery pipe 43 extends into the rotating part. The plurality of atomizing nozzles 44 are spaced apart on the delivery pipe 43 along the axial direction of the delivery pipe 43.

[0061] Specifically, the oil pump 42 is a metering pump.

[0062] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0063] In practical use, the driver 33 drives the connecting seat 31 to move, and the connecting seat 31 drives the connecting piece 32 to move to a vertical position. At this time, the mounting base 21 and the rotary drum 22 are both in a horizontal position. Then, the first conveyor belt 5 is started to transport a certain amount of diammonium phosphate semi-finished product granules into the rotary drum 22. Then, the drive motor 233 drives the gear 232 to rotate. The gear 232 meshes with the gear ring 231 to drive the rotary drum 22 to rotate, so that the diammonium phosphate semi-finished product granules continuously tumble inside. Then, the oil pump 42 is started to draw the oil in the oil storage tank 41 to the conveying pipe 43 and spray it onto the rotary drum through the atomizing nozzle 44. Within 22, the anti-caking agent is evenly adhered to the surface of the semi-finished particles, forming a protective layer to prevent clumping. After coating, the oil pump 42 is turned off, and the driver 33 drives the connecting seat 31 to move. The connecting seat 31 drives the connecting piece 32 to move to an inclined state. At this time, both the mounting base 21 and the rotary drum 22 are in an inclined state. The driving cylinder 28 drives the second retaining ring 27 to move away from the rotary drum 22, thereby opening the discharge end of the rotary drum 22. Under the action of its own gravity, the diammonium phosphate particles move quickly towards the discharge end of the rotating part, thereby achieving the purpose of quickly discharging the diammonium phosphate particles and improving production efficiency.
