Background
Currently, granulation equipment used for producing granulated fertilizers in the fertilizer industry is mainly divided into a granulator and a granulation tower. The granulation tower is generally used due to simple structure, energy conservation and environmental protection. The granulation tower has the working principle that the molten liquid material is uniformly and stably sprayed into the granulation tower through a granulation nozzle, and sprayed small liquid drops fall from the top to the bottom of the tower from top to bottom under the action of gravity; in the falling process, the small liquid drops of the materials are in countercurrent contact with cooling air in the granulation tower, and the small liquid drops are cooled and crystallized to form small solid particles, namely a prototype of a fertilizer product.
The granulating nozzle in the granulating tower is a key part of the granulating process. When the prilling spray head is arranged in the central position of the prilling tower in a single way, the problem of spray head replacement in the continuous production situation is involved. The preparation process of the granulating solution is generally continuous, and in order to not influence the preparation of the solution and improve the production efficiency, the time consumed for replacing the granulating spray head is required to be very short, and the preparation process is preferably completed within 10 minutes. If the granulation nozzle replacement process is long in time consumption, granulation solution generated in the granulation solution production process, which is a preposed process of granulation, can be deposited in the system because the granulation solution cannot be used for granulation in time, and the granulation solution generated in the replacement process of the nozzles cannot be stored in buffer tanks (tanks) and the like in the system is deposited, so that the buffer tanks (tanks) overflow and the buffer capacity is lost, and the granulation solution production process is inevitably stopped in the whole production line due to continuous development, which causes great economic loss. Because the granulating solution may be mixed with a small amount of impurities or liquid with poor fluidity and high viscosity, the spray holes of the granulating spray head are generally between 1.0 mm and 4.0mm, the aperture is small, and the spray head can be blocked after the granulating process runs for a period of time, and the spray head blocked in the granulating tower needs to be replaced by a clean and unblocked spray head. The replacement process of the spray head is required to be simple, convenient, fast, time-saving, labor-saving and labor-saving. At present, the replacement mode of the spray head in the granulation tower is to pull up the spray head to be replaced through an electric or manual hoisting machine, then turn a spray head support mechanism to the side, and then drop the clean spray head into the placing position through the electric or manual hoisting machine, so that the whole process is complex and time-consuming, mechanical devices and accessories are more, the requirement on equipment installation space is also larger, at least two persons are required to operate simultaneously, the labor intensity is high, and the problem that the industry development is restricted is solved.
