Description

Technical Field

[0001] The invention belongs to the technical field of compound fertilizer production, and in particular relates to a high-tower granulation compound fertilizer collecting device. Background Art

[0002] The high-tower granulation compound fertilizer collecting device is an important equipment on the high-tower granulation compound fertilizer production line. The high-tower granulation technology is to send the raw material mixed slurry into the high-tower granulator for spraying and granulation. The granulated material sprayed into the granulation tower by the granulator interacts with the air (refrigerant) rising from the bottom of the tower to exchange heat during the process of descending from the high tower. After being air-cooled and solidified into a uniformly distributed spherical granular product, it falls to the bottom of the tower. The granular material falling to the bottom of the tower is collected and processed, such as a high-tower granulation compound fertilizer collecting device proposed in the patent announcement number CN219272966U.

[0003] In the process of compound fertilizer high-tower granulation and collection, particles fall from a height and are easily broken when colliding with the collecting device and being transported in the collecting device. The broken particles will affect the particle size distribution of the product and reduce the product quality. When the granulated material in the granulation tower descends in the high tower, the rising gas at the bottom of the tower exchanges heat with the granular material to form particles. However, the temperature of the granular material falling on the aggregate plate is still high, causing the granular material falling on the aggregate plate to stick to the aggregate plate. The aggregate plate needs to be cleaned manually in the later stage, which is time-consuming and labor-intensive and affects the continuity of the collecting device. Summary of the invention

A synchronous screw 78 is rotatably sleeved on the inner wall of the bearing seat 77 through a ball bearing. The statistical shell 710 is also fixedly installed on the outer wall of the support frame 8, and the synchronous screw 78 is rotatably arranged inside the statistical shell 710. The rod wall of the synchronous screw 78 is threadedly sleeved with a synchronous seat 711, and a pointer 712 is fixedly connected to one side of the synchronous seat 711.

The outer wall of the statistical shell 710 is also fixedly installed with a statistical scale plate 714 arranged corresponding to the position of the pointer 712, and the outer wall of the synchronous seat 711 is fixedly connected with a limiting slider, and the inner wall of the statistical shell 710 is provided with a limiting slide groove that matches the limiting slider for sliding connection, which can automatically count the collected number of compound fertilizer particles, making it convenient for the staff to know the material collection information in time.

[0026] The PLC controller 11 is fixedly mounted on the support frame 8 and is electrically connected to the bottom buffer cooling mechanism 2, the material discharging auxiliary mechanism 5 and the in-position trigger mechanism 6 respectively.

[0027] The operating principle of the present invention is described as follows: the collecting barrel 1 is installed at the bottom of the granulation tower. During the granulation process, the compound fertilizer particles will fall into the collecting barrel 1. The PLC controller 11 controls the air cooler 24 to work. The air cooler 24 supplies air into the buffer shell 21 and sprays air through a plurality of air blowing heads 23, providing a buffer force for the descent of the compound fertilizer particles, and causing the compound fertilizer particles to be ejected to the inner wall of the collecting barrel 1, and fall into the receiving box 10 along the inner wall of the collecting barrel 1 through the gap between the collecting barrel 1 and the buffer shell 21 for collecting. This not only reduces the final falling speed of the compound fertilizer particles, reduces the impact force between the compound fertilizer particles and the collecting barrel 1, and avoids the problem that the compound fertilizer particles are easily broken, but also the cold air blown out by the air blowing head 23 can further cool the compound fertilizer particles, avoiding the compound fertilizer particles from generating greater viscosity due to excessive temperature, which will cause the compound fertilizer particles to adhere to the inner wall of the collecting barrel 1, which not only affects the continuity of collecting, but also requires frequent cleaning of the inner wall of the collecting barrel 1. A part of the cold air supplied by the air cooler 24 into the buffer shell 21 is transported through the air supply pipe 33. First, the cold air transported in the air supply pipe 33 drives the forced wind wheel 37 in the power shell 36 to rotate (in the granulation process of the compound fertilizer particles, the granulation speed is fast and the number of falling compound fertilizer particles is large, so a large buffer airflow is required to buffer and slow down the falling compound fertilizer particles. Therefore, the air entering the air supply pipe 33 has sufficient driving force to cause the forced wind wheel 37 to rotate). The forced wind wheel 37 drives the transmission shaft 31 to drive the stirring paddle 32 to rotate, so that the stirring paddle 32 breaks up the compound fertilizer particles that are agglomerated together to avoid the problem of compound fertilizer particles agglomerating together and causing discharge blockage. The stirring paddle 32 is made of metal conductive material to disperse the compound fertilizer particles. The static electricity accumulated on the compound fertilizer particles is conducted out by the transmission shaft 31 and the rotating conductor 41 using the grounding wire 43, so that the static electricity on the compound fertilizer particles is quickly eliminated, and the static electricity carried by the compound fertilizer particles is further avoided, which makes the compound fertilizer particles more agglomerated, and thus makes it difficult to break up or there will be a problem of discharge blockage. The air supply pipe 33 further transports the cold air to the cleaning head 34 for spraying, and the cleaning head 34 provides a downward blowing force to the inner wall of the receiving barrel 1, which assists the compound fertilizer particles to fall along the inner wall of the receiving barrel 1 better for collecting, and further exchanges the heat accumulated on the inner wall of the receiving barrel 1, so as to avoid the problem that the heat increase on the receiving barrel 1 due to the contact of the compound fertilizer particles will cause reverse heating of the compound fertilizer particles; The conveyor 9 transfers the receiving box 10 to the lower end of the receiving barrel 1, and the PLC controller 11 controls the multiple hydraulic cylinders 51 to work, thereby pushing the two U-shaped lifting plates 52 upward, so that the multiple plug-in columns 56 are connected to the plug-in grooves 57 opened at the lower end of the receiving box 10, and the receiving box 10 is limited, and the receiving box 10 is pushed upward to a position separated from the conveyor 9 until the L-shaped trigger plate 62 contacts the trigger switch 61. At this time, the PLC controller 11 controls the hydraulic cylinder 51 to stop the action, so that the interval between the receiving box 10 and the receiving barrel 1 is reduced, so as to avoid the problem of large impact force of receiving materials caused by excessive height between the compound fertilizer particles falling through the receiving barrel 1 and the receiving box 10; At this time, the PLC controller 11 synchronously controls the drive motor 59 to move, and the drive motor 59 drives the cam 510 to rotate through the drive shaft 58. When the protruding portion of the cam 510 is pushed on one side of the receiving box 10, the receiving box 10 moves relatively through the sliding action of the sliding seat 54 on the guide slide bar 53. When the protruding portion of the cam 510 leaves one side of the receiving box 10, the receiving box 10 is reset and moved under the action of the reset spring 55, so that the receiving box 10 presents a reciprocating movement process, providing a vibration force to the receiving box 10, so that the compound fertilizer particles falling into the receiving box 10 are more evenly and tightly filled in the receiving box. A torque sensor is installed in the material box 10 and at the output end of the drive motor 59. When the torque sensor detects that the output torque of the drive motor 59 reaches the threshold value, it indicates that the weight of the compound fertilizer particles collected in the material receiving box 10 meets the standard. At this time, the PLC controller 11 first controls the granulator to suspend the granulation work, and then controls the drive motor 59 to stop the action, and makes the hydraulic cylinder 51 drive the material receiving box 10 to reset and move downward, so that the material receiving box 10 falls on the conveyor 9 again. The PLC controller 11 controls the conveyor 9 to drive the material receiving box 10 filled with materials to move, so that the subsequent empty material receiving box 10 moves to the material receiving position again, and performs continuous material receiving work; When the receiving box 10 filled with materials moves on the conveyor 9, the receiving box 10 will be squeezed on the deflection plate 73, and the deflection plate 73 will drive the linkage shaft 72 to rotate by overcoming the action of the torsion spring 75. At this time, the linkage shaft 72 will drive the synchronous screw 78 to rotate by itself through the ratchet assembly 79, and the threaded sleeve connection between the synchronous screw 78 and the synchronous seat 711 makes the synchronous seat 711 drive the pointer 712 to move relatively, so that the relative indication position of the pointer 712 on the statistical scale plate 714 changes. When the receiving box 10 leaves the deflection plate 73, the torsion spring 75 makes the linkage shaft 72 drive the deflection plate 73 to reset and move, and the limit plate 76 makes the deflection plate 73 not have too large a deflection angle, waiting for the next contact trigger of the receiving box 10, and under the reverse rotation of the linkage shaft 72, Due to the unidirectional transmission of the ratchet assembly 79, the linkage shaft 72 will not drive the synchronous screw 78 to rotate. The position of the pointer 712 relative to the statistical scale plate 714 can be used to quickly determine how many receiving boxes 10 filled with compound fertilizer particles have completed the work. It should be noted that under the action of the reset spring 55, when the receiving box 10 completes the material receiving work, the receiving box 10 will be relatively reset to the initial position. The receiving box 10 is located in front of the deflection plate 73. Under the drive and transfer of the conveyor 9, the receiving box 10 can contact the deflection plate 73, thereby driving the deflection plate 73 to perform relative deflection. During the extrusion contact work between the receiving box 10 and the deflection plate 73, since the receiving box 10 no longer has the power to move back and forth, there will be no problem that the receiving box 10 cannot squeeze the deflection plate 73 to produce a deflection action.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
