Description

Technical Field

Fertilizers that contain two or three of the three nutrients nitrogen, phosphorus and potassium and can indicate their content during the production process are called compound fertilizers or mixed fertilizers.

[0003] At present, compound fertilizers on the market often produce tail gas during the granulation process. In the current production process, if the tail gas in the production process is not cleaned and purified in time and directly discharged into the atmosphere, it is easy to affect the surrounding atmospheric environment.

[0053] The specific application of this embodiment 1 is:

[0054] Before using the device, the two second ear plates 503 in the primary treatment component 5 are respectively plugged and matched to the two first threaded columns 406 fixed on one side of the mounting ring 405, until the two second ear plates 503 are respectively and simultaneously in contact with one side of the mounting ring 405, and the primary treatment component 5 is detachably threadedly fixedly connected through the threaded rotation connection between the external nut and the first threaded column 406, so as to facilitate the disassembly and replacement of the primary treatment component 5 at a later time;

[0056] After the above preparation steps are completed, the rotating cylinder 601 and the annular groove 602 opened on the top are placed on the annular rail 312, so that the entire rotating member 6 can rotate on the annular rail 312 later. After the rotating cylinder 601 and the annular groove 602 opened on the top are placed on the annular rail 312, the threaded rod 319 is rotated to drive the sliding plate 316 threadedly connected to the side surface of the threaded rod 319 to move on the inner wall of the cross groove 315 until the arc surface of the arc plate 317 fixed to one side of the sliding plate 316 and the limiting ring groove 604 opened on the outer side surface of the rotating cylinder 601 below the gear ring 603 are fitted with each other, and then the threaded rod 319 is stopped to prevent the entire rotating member 6 from shaking up and down when it rotates on the annular rail 312 later, so as to avoid affecting the purification and cleaning process in the later stage.

[0057] After the tail gas from compound fertilizer production enters the interior of the device from the tail gas exhaust pipe of the compound fertilizer granule production and molding equipment (the compound fertilizer granule production and molding equipment is a prior art, not shown in the figure, and will not be elaborated on here. In addition, when the device processes the tail gas from compound fertilizer production, the air inlet end of the air inlet cylinder 401 in this setting is connected to the tail gas exhaust pipe of the compound fertilizer granule production and molding equipment through a connecting hose in advance.

Then, the sealing gasket 320 fixed on one side of the positioning ring 307 and the annular sealing groove 703 opened at the other end of the plug-in tube 701 are engaged with each other to prevent the compound fertilizer production tail gas from leaking out of the plug-in connection of the fixing member 7 when the compound fertilizer production tail gas is subjected to secondary cleaning treatment, thereby polluting the surrounding atmospheric environment.

[0061] During the use of the device, the two reciprocating rods 409 fixed to the outer bottom of the air intake cylinder 401 reciprocate up and down in the connecting tube 306 and the plug-in cylinder 701, so that the ends of the two reciprocating rods 409 fixed to the outer bottom of the air intake cylinder 401 are synchronously and repeatedly in intermittent contact with the end surface of the sliding ring 804, and thereby provide an intermittent force for the reciprocating sliding process of the sliding ring 804, so that the third spring 802 fixedly connected between the fifth ear plate 801 and the moving plate 803 is repeatedly compressed or pulled up, thereby driving the columnar resin block 805 fixed between the two third springs 802 on one side of the sliding ring 804 to repeatedly move up and down inside the plug-in cylinder 701, and finally The columnar resin block 805 fixed between the two third springs 802 on one side of the sliding ring 804 is fully in contact with the compound fertilizer production tail gas after the first-level purification and cleaning treatment. During the entire treatment process, the original fixed state of the columnar resin block 805 is replaced by a reciprocating movement, thereby increasing the contact area between the columnar resin block 805 and the compound fertilizer production tail gas after the first-level purification and cleaning treatment, increasing the absorption efficiency between the columnar resin block 805 and the compound fertilizer production tail gas after the first-level purification and cleaning treatment, improving its absorption effect on volatile organic waste gas inside the tail gas, avoiding the volatile organic waste gas in the compound fertilizer production tail gas after the first-level purification and cleaning treatment from being discharged into the external atmospheric environment, and preventing it from causing pollution to the external atmospheric environment.
