Description

Technical Field

[0001] This utility model relates to the field of phosphorus nitrate molten slurry nozzle technology, specifically a phosphorus nitrate molten slurry nozzle. Background Technology

[0002] The phosphorus nitrate molten slurry nozzle heats phosphorus nitrate particles to a molten state at high temperature (120-165℃), and then sprays and atomizes them under the action of low-pressure steam (0.3-0.8MPa) to form uniform particles. The slurry is used in a spray granulator to coat the returned particles and form a multi-layer structure, so that the granulation and pelletizing rate is ≥90%.

[0003] However, it still has some drawbacks. For example, the current phosphorus nitrate molten slurry nozzles are relatively simple to connect during use, and are generally connected with screws. They require tools for installation and disassembly, which is inconvenient. Moreover, the flow of slurry will accelerate the loosening of the threads, affecting the use of the nozzle.

[0004] To address the aforementioned issues, this application proposes a phosphorus nitrate molten slurry nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a phosphorus nitrate molten slurry nozzle to solve the problem of inconvenient disassembly and installation in the prior art mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a phosphorus nitrate molten slurry nozzle, comprising a slurry nozzle, wherein a connecting inner tube and a sealing ring are fixedly installed on one outer surface of the slurry nozzle, the sealing ring is located on the outer wall of the connecting inner tube, positioning rods are fixedly installed on both outer surfaces of the connecting inner tube, and slots are provided at both the upper and lower ends of the connecting inner tube.

[0007] Preferably, the outer wall of the connecting inner tube is detachably connected to the inner cavity of the connecting outer tube. Positioning grooves are provided on both sides of the inner cavity of the connecting outer tube, a retaining groove is provided on one side of the connecting outer tube, and a slurry pipe is fixedly connected to the other side of the connecting outer tube. A steam pipe is provided on one side of the slurry pipe, and a steam nozzle is fixedly installed on one side of the outer wall of the steam pipe.

[0008] Preferably, the outer wall of the connecting outer tube is threaded with a connecting threaded bolt, which penetrates the inner cavity of the slot.

[0009] Preferably, the connecting outer tube is tightly fitted to one side of the slurry nozzle.

[0010] Preferably, the sealing ring is detachably connected to the inner cavity of the slot, and the positioning rod is detachably connected to the inner cavity of the positioning groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the coordinated design of an inner connecting tube, a sealing ring, a positioning rod, a slot, an outer connecting tube, a positioning groove, a retaining groove, and a connecting threaded bolt, facilitates the disassembly and installation of the nozzle. First, the inner connecting tube is inserted into the inner wall of the outer connecting tube, allowing the positioning rod to engage in the positioning groove and rotate, preventing it from falling out. The insertion and engagement of the inner and outer connecting tubes, combined with the precise alignment of the positioning rod and the positioning groove, enables rapid installation and disassembly of the slurry nozzle, significantly improving maintenance efficiency. Simultaneously, the sealing ring engages in the retaining groove, enhancing sealing performance. The design also features a detachable mechanism. The sealed structure facilitates the replacement of worn parts, reduces maintenance costs, and ensures a tight fit between one side of the connecting outer tube and the other side of the slurry nozzle. The sealing ring and the groove form the first seal, while the tight fit between the connecting outer tube and the slurry nozzle provides a second seal, effectively preventing high-pressure slurry leakage. The nozzle is then connected and secured using threaded bolts, facilitating easy disassembly and installation without the need for tools. The molten nitric acid slurry sprayed from the nozzle disperses the slurry, improving the granulation and pelletizing rate, saving start-up and shutdown time, and increasing efficiency.
