Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to an anti-adhesion mechanism for the wall of a high-tower compound fertilizer tank. Background Technology

[0002] Compound fertilizer produced by high-tower granulation has relatively uniform nutrient content, with each granule containing essentially the same amount of nutrients. This ensures even nutrient release and significantly improves fertilizer absorption and utilization. Therefore, most fertilizer plants currently use high-tower granulation technology for compound fertilizer production. During high-tower granulation, the fertilizer inside the tower eventually falls into a conical guide trough below, and is then conveyed to the next process step via a conveyor belt. In this process, when the compound fertilizer granules sprayed from the granulation nozzles reach the bottom of the tower, they are still at a relatively high temperature and do not completely solidify. When they reach the side wall of the conical guide trough at the bottom of the tower, they easily adhere to the side wall and solidify into a sludge layer. As granulation continues, the thickness of this sludge layer increases. To ensure normal fertilizer collection, intermittent shutdowns are required to clean the sludge layer, which is time-consuming, labor-intensive, severely impacts production efficiency, and also poses certain risks.

[0003] A Chinese utility model patent (publication number: CN215389119U) discloses a nitro tower-type melt granulation compound fertilizer production device, including a granulation tower, a conical guide trough, a support plate, and a trough wall anti-adhesion mechanism. The trough wall anti-adhesion mechanism includes a toothless slewing bearing, an outer gear ring, a drive wheel, a drive motor, a support arm, and a scraper. The outer ring of the toothless slewing bearing is mounted on the support plate, and the outer gear ring is mounted on the upper part of the inner ring of the toothless slewing bearing. The drive motor is used to drive the drive wheel to rotate, and the drive wheel meshes with the outer gear ring. The lower end of the support arm is fixedly connected to the inner side wall of the outer gear ring, and the upper end of the support arm extends from the discharge port end of the conical guide trough into the interior of the conical guide trough. The scraper is mounted on the upper end of the support arm, and the blade of the scraper is in contact with the side wall of the conical guide trough. The anti-sticking mechanism on the trough wall of the device can effectively prevent the phenomenon of slagging on the conical guide trough, thereby ensuring the continuous granulation of compound fertilizer and improving the production efficiency of compound fertilizer granules.

[0004] However, the following problems were found in the implementation of the relevant technologies:

[0005] When compound fertilizer granules fall from top to bottom inside the conical feed trough, they come into contact with the support arm and scraper, causing the compound fertilizer to stick to the surface of the support arm and scraper. At the same time, the scraper continues to contact the inner wall of the conical feed trough, which will damage the anti-adhesion coating on the inner wall surface of the conical feed trough.

[0006] Therefore, an anti-adhesion mechanism for the wall of a high-tower compound fertilizer tank is proposed. Utility Model Content

[0007] This utility model proposes an anti-adhesion mechanism for the wall of a high-tower compound fertilizer tank, which solves the problem in related technologies where the support arm and scraper are located inside the conical guide channel. When compound fertilizer particles fall from top to bottom, they come into contact with the support arm and scraper, causing the compound fertilizer to stick to the surface of the support arm and scraper. At the same time, the scraper continuously contacts the inner wall of the conical guide channel, which damages the anti-adhesion coating on the inner wall surface of the conical guide channel.

[0008] The technical solution of this utility model is as follows: an anti-adhesion mechanism for the wall of a high-tower composite fertilizer tank, comprising:

[0009] The system comprises: a tall tower for forming compound fertilizer granules using a solvent; a conical guide shell for fitting the compound fertilizer granules formed inside the tall tower; a connector for fitting the tall tower and the conical guide shell; an installation component for fixing the tall tower and the conical guide shell; and a conical guide cover installed inside the conical guide shell, the outer surface of which is equipped with an electric vibrator.

[0010] The present invention is further configured such that the connecting member includes a base ring one fixedly connected to the surface of the conical guide shell, a base ring two fixedly connected to the surface of the tower, and a plurality of connecting holes.

[0011] The present invention is further configured such that the mounting component includes a bolt disposed inside the connecting hole, a washer sleeved on the surface of the bolt, a spring sleeved at the center of the bolt surface, and a nut threadedly connected to the outer surface of the bolt.

[0012] The present invention is further configured such that the inner wall of the conical guide shell is provided with a mounting groove for the conical guide cover, and the bottom end of the tower is provided with a retaining groove for the conical guide cover.

[0013] The present invention is further configured such that the conical guide cover is made of stainless steel, and the inner wall of the conical guide cover is coated with polytetrafluoroethylene.

[0014] The present invention is further configured such that the inner wall of the retaining groove is provided with multiple sets of pressing members; the pressing members include a mounting groove formed on one side of the retaining groove and a compression spring provided inside the mounting groove.

[0015] The present invention is further provided with a rubber ring on the inner wall of the holding groove that matches the conical guide cover.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] This application has a reasonable structure. When the compound fertilizer falls from top to bottom, it comes into contact with the compound fertilizer through the conical guide cover inside the conical guide shell. At this time, the polytetrafluoroethylene coating on the inner wall surface of the conical guide shell allows the compound fertilizer to slide down. At the same time, the conical guide cover is vibrated by an electric vibrator to assist the polytetrafluoroethylene coating, accelerate the sliding speed of the compound fertilizer, and prevent the compound fertilizer from sticking to the polytetrafluoroethylene coating surface. In summary, this avoids the problem that when the support arm and scraper are inside the conical guide groove, they will come into contact with the support arm and scraper when the compound fertilizer particles fall from top to bottom, and the scraper will continuously come into contact with the inner wall of the conical guide groove, which would damage the anti-adhesion coating on the inner wall surface of the conical guide groove.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides an anti-adhesion mechanism for the wall of a high-tower compound fertilizer tank, comprising: a high tower 1, which is used for molding compound fertilizer solvent; a conical guide shell 2, which is used to cooperate with the compound fertilizer granules molded inside the high tower 1, and the inner surface of the conical guide shell 2 is provided with a rubber buffer sheet for cooperating with a conical guide cover 8; a connecting piece 3 for cooperating with the high tower 1 and the conical guide shell 2; an installation piece 4 for fixing the high tower 1 and the conical guide shell 2; and a conical guide cover 8, which is installed inside the conical guide shell 2, and the outer surface of the conical guide cover 8 is provided with an electric vibrator 9.

[0027] Furthermore, the connector 3 includes a base ring 301 fixedly connected to the surface of the conical guide shell 2, a base ring 302 fixedly connected to the surface of the tower 1, and a plurality of connecting holes 303. The mounting component 4 includes a bolt 401 disposed inside the connecting hole 303, a washer 402 sleeved on the surface of the bolt 401, a spring 403 sleeved on the center of the surface of the bolt 401, and a nut 404 threadedly connected to the outer surface of the bolt 401.

[0028] Specifically, the bolt 401 passes through the connecting hole 303 on the surface of base ring 1 301 and base ring 2 302. Then, the gasket 402 and spring 403 are respectively fitted onto the surface of the bolt 401. Finally, the nut 404 is connected to the bolt 401 to achieve the installation of the conical guide shell 2 at the bottom of the tower 1.

[0029] Furthermore, the inner wall of the conical guide shell 2 is provided with a mounting slot for the conical guide cover 8, and the bottom end of the tower 1 is provided with a retaining groove 6 for the conical guide cover 8. The conical guide cover 8 is made of stainless steel, and the inner wall of the conical guide cover 8 is coated with polytetrafluoroethylene.

[0030] Specifically, when the compound fertilizer falls from top to bottom, it comes into contact with the conical guide cover 8 inside the conical guide shell 2. At this time, the polytetrafluoroethylene coating on the inner wall surface of the conical guide shell 2 causes the compound fertilizer to slide down. At the same time, the conical guide cover 8 is vibrated by the electric vibrator 9 to assist the polytetrafluoroethylene coating, accelerate the speed of the compound fertilizer sliding down, and prevent the compound fertilizer from sticking to the surface of the polytetrafluoroethylene coating.

[0031] Furthermore, the inner wall of the holding groove 6 is provided with multiple sets of extrusion members 7; the extrusion member 7 includes an installation groove 701 opened on one side of the holding groove 6 and a compression spring 702 provided inside the installation groove 701. The inner wall of the holding groove 6 is provided with a rubber ring 5 that cooperates with the conical guide cover 8, and the rubber ring 5 is in contact with the compression spring 702.

[0032] Specifically, one end of the conical guide cover 8 is located inside the retaining groove 6, and its end face is in contact with the rubber ring 5. When the electric vibrator 9 causes the conical guide cover 8 to vibrate, the rubber ring 5 is subjected to force, causing the compression spring 702 to shake, thereby providing space for the conical guide cover 8 to vibrate.

[0033] The workflow for this application is as follows:

[0034] When the compound fertilizer falls from top to bottom, it comes into contact with the conical guide cover 8 inside the conical guide shell 2. At this time, the polytetrafluoroethylene coating on the inner wall surface of the conical guide shell 2 causes the compound fertilizer to slide down. At the same time, the conical guide cover 8 is vibrated by the electric vibrator 9 to assist the polytetrafluoroethylene coating, accelerate the speed of the compound fertilizer sliding down, and prevent the compound fertilizer from sticking to the surface of the polytetrafluoroethylene coating.

[0035] In addition, when the electric vibrator 9 causes the conical guide cover 8 to vibrate, its rubber ring 5 is subjected to force, causing the compression spring 702 to shake, thereby providing space for the conical guide cover 8 to vibrate. At the same time, the rubber buffer sheet prevents the conical guide cover 8 from colliding with the conical guide shell 2 when it vibrates.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
