Description

Technical Field

[0001] This utility model belongs to the technical field of high-tower granulation equipment, and particularly relates to a granulation spray blue quick loading and unloading component. Background Technology

[0002] Because the viscosity of nitrogen, phosphorus, and potassium in the melt-process compound fertilizer production is hundreds, thousands, or even tens of thousands of times greater than that of pure urea melt during the melting and compounding process, and it contains a large number of suspended solid particles, traditional ammonium nitrate or urea spray granulation processes simply cannot maintain production. To address the challenge of achieving the desired output, particle size, pass rate, particle strength, and dust emission in a tower rotary spray granulation process for high-viscosity molten materials containing a large proportion of suspended solid particles, while also meeting the requirements of industrial production for continuous single-machine operation time and rapid nozzle replacement, in addition to developing a reasonable melt slurry process, a granulator capable of meeting these requirements is essential. To this end, a differential granulator has been developed and achieved commercial success. The differential granulator has two working shafts—an inner shaft and an outer shaft. The inner shaft drives the granulation spray nozzle, and the outer shaft drives the material distribution mechanism. However, because the melt inevitably contains solids exceeding the process requirements, the nozzles are easily clogged, severely affecting the finished product yield and granulation output. Therefore, to maintain the finished product yield, frequent shutdowns and nozzle replacements are necessary, especially when producing high-viscosity formulations, where replacement is required almost every two hours. This also places higher demands on the safety, convenience, and speed of loading and unloading the granulation spray head. However, existing granulation spray heads are connected to the main shaft by multiple bolts, requiring two operators to install or remove nuts using a wrench. This not only results in low efficiency and high labor intensity but also poses safety hazards. Utility Model Content

[0003] This invention provides a quick loading and unloading assembly for granulation and spraying blue, overcoming the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model is: a quick loading and unloading assembly for granulation spraying, including a main shaft flange and a spraying flange. The main shaft flange is coaxially and fixedly connected to the lower end of the main shaft of the granulation nozzle, and the spraying flange is coaxially and fixedly connected to the bottom end of the granulation spraying nozzle.

[0005] The outer periphery of the main shaft flange has an annular groove and several notches evenly distributed at the bottom that penetrate the annular groove. The notches divide the annular groove into several discontinuous segments. The side of each segment of the annular groove near the bottom of the main shaft flange is a spiral surface, and the side of each segment of the annular groove away from the bottom of the main shaft flange is a flat surface. All spiral surfaces have the same direction of rotation and helix angle.

[0006] The inner hole of the blue-sprayed flange has several concentric arc-shaped bosses that are one-to-one opposite to the notch. The upper end face of each arc-shaped boss is a plane, and the lower end face is a spiral surface II. The spiral surface II has the same direction of rotation and helix angle as the spiral surface I.

[0007] The granulation spray blue is fitted around the main shaft, and the arc-shaped boss enters the annular groove through the notch. Rotating the granulation spray blue causes the upper and lower end faces of the arc-shaped boss to abut against the upper and lower sides of the annular groove, respectively, connecting the granulation spray blue to the main shaft as one unit. Rotating the granulation spray blue in the opposite direction can remove the granulation spray blue from the main shaft.

[0008] Two notches are symmetrically arranged, and the spiral surfaces are symmetrically distributed between the notches. The helix angle is 2.5-4.5 degrees.

[0009] The upper end of the main shaft flange has a connecting plate, which is coaxially fixed to the lower end of the main shaft of the granulation nozzle by bolts; the blueing flange has a flange plate, which is coaxially fixed to the bottom end of the granulation blueing nozzle by bolts.

[0010] The rotation directions of the first and second helical surfaces are the same as the rotation direction of the main shaft.

[0011] The upper end of the connecting plate is provided with an annular recess that is adapted to the lower end of the spindle. The annular recess is fitted onto the lower end of the spindle and connected by bolts.

[0012] The flange has an annular boss at its upper end, which is inserted into the mounting hole at the bottom of the granulation spraying.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model improves the traditional bolt connection to a spiral surface connection. When loading and unloading granulation spraying, the granulation spraying only needs to be rotated by one angle to achieve the purpose of loading or unloading, realizing the rapid loading and unloading of granulation spraying, greatly reducing the labor intensity of operators on the tower, and also improving the safety of operation.

[0015] 2. This utility model achieves self-locking through the helix angle of the helical surface, ensuring reliable connection. Furthermore, the rotation direction of the helical surface is the same as the rotation direction of the main shaft, guaranteeing that the blueing flange does not loosen when the granulation nozzle rotates.

[0016] 3. This utility model consists of two flange components, which are simple in structure, low in cost, highly practical, and have promising prospects for industry application. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in detail with reference to specific embodiments.

[0024] A quick-loading assembly for granulation and bluing spraying includes a main shaft flange 1 and a bluing flange 2. The main shaft flange 1 is coaxially and fixedly connected to the lower end of the main shaft 3 of the granulation nozzle, and the bluing flange 2 is coaxially and fixedly connected to the bottom end of the granulation and bluing spraying head 4. The main shaft flange 1 has an annular groove 1-3 on its periphery and several notches 1-4 evenly distributed at its bottom, which are connected to the annular groove 1-3. The notches 1-4 divide the annular groove 1-3 into several discontinuous segments. The side of each segment of the annular groove 1-3 near the bottom of the main shaft flange 1 is a helical surface 1-5, and the side of each segment of the annular groove 1-3 away from the bottom of the main shaft flange 1 is a flat surface. All helical surfaces 1-5 have the same direction of rotation and helix angle. The bluing spraying head... The inner hole 2-2 of flange 2 has several concentric arc-shaped bosses 2-3 that are one-to-one opposite to the notch 1-4. The upper end face of each arc-shaped boss 2-3 is a plane, and the lower end face is a spiral surface 2-4. The spiral surface 2-4 has the same direction of rotation and helix angle as the spiral surface 1-5. The granulation spraying blue 4 is fitted around the main shaft 3, and the arc-shaped bosses 2-3 enter the annular groove 1-3 through the notch 1-4. Rotating the granulation spraying blue 4 makes the upper and lower end faces of the arc-shaped bosses 2-3 abut against the upper and lower sides of the annular groove 1-3, connecting the granulation spraying blue 4 to the main shaft 3 as one unit. Rotating the granulation spraying blue 4 in the opposite direction can remove the granulation spraying blue 4 from the main shaft 3.

[0025] Figure 1 , Figure 2 This illustration shows one embodiment of the present invention, in which two notches 1-4 are symmetrically arranged, and the spiral surfaces 1-5 are symmetrically distributed between the notches 1-4, with a helix angle of 2.5-4.5 degrees. The rotation direction of the spiral surfaces 1-5 and 2-4 is the same as the rotation direction of the main shaft 3, to ensure that the blueing flange 2 does not loosen when the granulation nozzle rotates.

[0026] Figure 3 , Figure 7 The connection structure between the spindle flange 1 and the lower end of the spindle 3 is shown. Specifically, the upper end of the spindle flange 1 has a connecting plate 1-1, and the upper end of the connecting plate 1-1 is provided with an annular recess 1-6 that is adapted to the lower end of the spindle 3. The annular recess 1-6 is fitted onto the lower end of the spindle 3 and connected by bolts.

[0027] Figure 4 , Figure 7 The connection structure between the main shaft flange 1 and the bottom of the blue spraying flange 2 is shown. Specifically, the blue spraying flange 2 has a flange 2-1, and the upper end of the flange 2-1 is provided with an annular boss 2-5. The annular boss 2-5 is inserted into the mounting hole at the bottom of the granulation blue spraying 4. The flange 2-1 is coaxially fixed to the bottom of the granulation blue spraying 4 by bolts.

[0028] Reference Figure 6 When the spiral surface 1-5 and the spiral surface 2-4 rotate in the left direction, rotating the granulation spraying blue 4 counterclockwise will lock the arc-shaped boss 2-3 and the annular groove 1-3, enabling the granulation spraying blue 4 to be installed quickly. Rotating the granulation spraying blue 4 clockwise will loosen the arc-shaped boss 2-3 and the annular groove 1-3, allowing the arc-shaped boss 2-3 to slide out of the notch 1-4, thereby quickly removing the granulation spraying blue 4 from the main shaft 3.

[0029] This invention greatly reduces the labor intensity of tower operators and improves operational safety. Tasks that previously required two operators can now be easily completed by one operator, reducing the number of workers required on the tower.
