Description

Technical Field

[0001] The invention relates to the technical field of fertilizer screening, in particular to an organic fertilizer granulation and screening device. Background Art

[0002] In order to facilitate storage and application, the organic fertilizer needs to be granulated. During the granulation process, a screening device is used to screen the fertilizer to cooperate with the granulation operation. For example, the patent announcement number is CN215313768U, which is an organic fertilizer screening device. The organic fertilizer is put into the feeding bin, and the two first crushing rollers in the coarse crushing chamber rotate, driving the driven crushing teeth and the active crushing teeth to rotate. Since the active crushing teeth are engaged with the driven crushing teeth, the organic fertilizer can be coarsely crushed; the coarsely crushed organic fertilizer falls from the first filter screen into the fine crushing chamber for crushing, and the fine crushing teeth in the fine crushing chamber further crush the organic fertilizer. The crushed organic powder falls from the second filter screen into the granulation drum. During the rotation of the drum, the organic powder can be squeezed into the holes, squeezed out from the holes to form particles, and fall into the collection bin.

[0003] When the existing granulation and screening device is in use, the fertilizer has a certain humidity, so it will be heated during the granulation and screening process to facilitate subsequent molding. However, the fine particles in the fertilizer may be more likely to adhere after heating, causing part of the fertilizer to stick to the screening holes. The screening holes are far away from the heating range, resulting in the fertilizer not being able to dry and fall off in time. If not handled in time, the fertilizer will stick and clump together and block the screening holes, which will affect the subsequent extrusion granulation operation. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an organic fertilizer granulation and screening device, which solves the problem that after heating, some fertilizers are more likely to adhere due to insufficient heating, thereby clogging the screening holes and affecting the granulation efficiency.

[0012] Preferably, a material blocking guide plate is fixedly mounted on the upper end of the rotating shaft, an offset groove is provided between the material blocking guide plate and the rotating shaft, and a plurality of air inlet channels are provided inside the rotating shaft.

[0013] Preferably, the upper end of the air inlet channel is located in the offset groove and the channel is arc-shaped, and the lower end of the air inlet channel is located inside the placement seat and the channel is straight and staggered with the fan blades.

[0014] Preferably, the collecting assembly includes an annular receiving plate, which is arranged on the inner wall of the discharge port, a collecting groove is opened inside the cylinder, a plurality of auxiliary sieve holes are opened on the surface of the annular receiving plate, the auxiliary sieve holes are communicated with the collecting groove, a gathering guide plate is arranged inside the collecting groove, and a bin door is arranged on the outside of the cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A number of screening holes are reserved inside the limiting tube rack, so that the screening holes can screen the fertilizer to prevent the fertilizer that has not been granulated from falling, so as to ensure that the fertilizer is granulated according to the screening holes as the standard during subsequent extrusion granulation. An interactive channel is opened inside the limiting tube rack, so that hot air can be transferred inside the interactive channel, thereby increasing the temperature of the limiting tube rack, avoiding the situation that part of the fertilizer is not yet dry during extrusion granulation, causing the fertilizer to stick to the screening holes, and then the accumulation of fertilizer causes the screening holes to be blocked during subsequent extrusion. The above structure can ensure that the screening extrusion area can be stably heated, avoiding the problem of reduced granulation efficiency and poor granulation effect caused by fertilizer blockage.

[0016] 2. By starting the driving motor, the shaft can be driven to rotate continuously, and the fertilizer can be gathered by using a shielding cover, and then extruded by rotating multiple counterweight blocks.

The extrusion roller can be used to extrude the fertilizer above the screening hole, and the fertilizer can be extruded and granulated in conjunction with the screening hole to realize fertilizer processing.

[0017] 3. The upper end of the air inlet channel is arc-shaped, so that when the shaft rotates, the surrounding air can be actively guided into the air inlet channel and discharged from the lower end so that the airflow will not directly contact the upper fertilizer, avoiding affecting the normal extrusion granulation. The airflow can enter the placement seat and cooperate with the fan blades to perform airflow diffusion operation, and then cooperate with the electric heating coil to heat the airflow to achieve heat diffusion; When the rotating shaft is driven to rotate by a driving motor, a plurality of fan blades can be driven to rotate accordingly, wherein the air inlet channel can be used to transport the outside air into the mounting seat, so that the air can be transported to the outside under the rotation of the plurality of fan blades, and the hot air can be distributed to the entire limiting pipe rack through a plurality of through holes and interactive channels, so as to ensure that the fertilizer stuck on it can be subsequently extruded into shape and fall after being heated, thereby effectively avoiding the problem that part of the fertilizer will accumulate and clog the screening holes due to the inability to dry the fertilizer after screening.

[0018] 4. After the fertilizer is extruded and granulated, it will fall downward. During the falling process, a number of exhaust ports are opened on the outside of the limiting pipe rack. The heated airflow will enter the dispersion slot from the exhaust port to disperse the airflow, and cooperate with the air guide seat to adjust the airflow blowing range to the discharge port, so that the debris remaining on the surface of the fertilizer can be blown out, and the annular receiving plate can be used to receive the blown fertilizer, and then the collecting slot is used to collect it, and the debris is guided to the warehouse door under the action of the gathering guide plate for easy collection by personnel.

[0029] Through the electrical connection between the brush 402 and the electric slip ring 7016, external power can be transmitted to the conductive cable 7017, so that the conductive cable 7017 can use the docking seat 7014 and the docking ring 7041 to energize multiple heating wires 704 without affecting the subsequent rotation operation, so that the heating wires 704 can heat the corresponding counterweight block 702, and the fertilizer above can be pre-heated. In addition, the conductive cable 7017 can also supply power to the electric heating coil 6033 to achieve heating of the airflow.

[0030] In the specific setting, the rotating shaft 7012 is located inside the mounting seat 603 and is provided with a plurality of fan blades 6032. A plurality of through holes 6031 are opened on the outside of the mounting seat 603 and are interconnected with the interactive channel 6021.
