In actual production, the discharge hole of the matching bin 1 can be connected with a plurality of horizontally arranged screw feeding devices to convey the matching material to the preheater, so that the feeding efficiency is ensured, and the uniformity of feeding distribution can be ensured.
The preheater 3 comprises a shell 3a, a discharge hole 5 is formed in the conical bottom of the shell 3a, a smoke inlet 6 is formed in the left shell 3a above the discharge hole 5, one end of the smoke inlet 6 is communicated with a kiln high-temperature smoke discharge flue, the top of the shell 3a is communicated with a dust collector 8 through a flue 7, a smoke exhaust pipe 8a is arranged on the upper portion of the dust collector 8, and a powder outlet 8b is formed in the bottom of the dust collector 8.
A group of first material guiding heat exchange plates 4 which are distributed up and down are arranged on the left inner wall of the shell 3a, the left end of each first material guiding heat exchange plate is connected with the left inner wall of the shell 3a in a matched mode, the right end of each first material guiding heat exchange plate is inclined downwards, and a certain distance is arranged between the end face of the right end and the shell 3 a. So that the first material guiding heat exchange plate 4 forms a slope surface which is inclined downwards and obliquely to the right side of the shell 3 a.
The inner wall of the right side of the shell 3a is also provided with a group of second material guiding heat exchange plates 4a which are distributed up and down, the right end of each second material guiding heat exchange plate 4a is connected with the inner wall of the right side of the shell 3a in a matched manner, the left end of each second material guiding heat exchange plate is arranged in a downward inclined manner, and a certain interval is arranged between the end face of the left end and the shell 3 a.
