[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0020] like Figure 1 , Figure 2 As shown, this utility model discloses a granulation pot for litharge granulation, comprising a pot body 1, a litharge feed pipe 4, a seed feed pipe 5, and a water spray pipe 6. The pot body 1 is a hollow, smooth, short, round handle with an opening, and is slightly inclined. Its central axis forms an angle α with the horizontal line, with α being 10°–20°. The outer wall of the pot body 1 has symmetrically arranged discharge ports 2 at both ends, each with an end cap 3. The two discharge ports 2 on the pot body 1 are of the same size and are symmetrically arranged to maintain balance during selection. The lower opening at the center of the right side wall of the pot body 1 is sealed and welded to one end of the litharge feed pipe 4; litharge powder is conveyed into the pot body through this feed pipe. The left side wall of the pot has an opening at the center. The seed feed pipe 5 is an L-shaped, hollow cylindrical tube consisting of a vertical pipe and a horizontal pipe connected to the lower end of the vertical pipe. A hopper for holding seeds is located at the upper end of the vertical pipe. The horizontal pipe extends horizontally into the pot body 1 through the opening. A water spraying device is vertically inserted into the lower middle part of the pot body 1 through the opening. The water spraying device includes a spray pipe 6, with a nozzle 7 at the end of the spray pipe 6 to fully disperse the water. The spray pipe 6 is a thin, hollow cylinder with an inner diameter of 3-8 mm. Water is sprayed into the pot body 1 through this spray pipe 6 and nozzle 7. The other end of the spray pipe 6 is connected to a water tank via a water pump.

[0021] like Figure 3As shown, the spray head 7 comprises a splash guard 10 which is a cylindrical structure with an open upper end and a closed lower end, the splash guard 10 has an inner diameter larger than the diameter of the water spray pipe 6, and a plurality of grooves 11 are arranged on the outer wall of the splash guard 10 for dispersing water flow. The spray head 7 is connected to the lower end of the water spray pipe 6 through two support bars 8 and a connecting rod 9, wherein the two support bars 8 form a cross shape and are connected to the lower end of the water spray pipe 6, and the connecting rod 9 is a thin column, one end of which is connected to the lower end of the support bar 8, and the other end is connected to the middle part of the splash guard 10.
