[0018] By using the above technical scheme, the two fixing rods are arranged in parallel with each other, the fixing base can be clamped, the fixing base can be more stably fixed, the air supply fan blades are reduced, the diffuser produces larger shaking when rotating, the effect of the ceramic blowing is affected, the ceramic can be better dried, and the drying effect of the ceramic is ensured.

[0019] Preferably, the diffuser is provided with a plurality of exhaust pipes arranged in a direction away from the diffuser.

Due to the hot air generated by the fan blades, the wind force will be weakened as the length of the diffuser increases, resulting in a certain gap between the hot air at the bottom and the hot air at the location. The use of such a designed diffuser can make the wind pressure gradually increase as the inner diameter of the cavity decreases during the flow of the hot air, thereby ensuring that the wind force discharged at each position of the exhaust port is approximately the same, so as to ensure that the drying degree of the ceramic in the drying room is the same, and improve the drying effect of the ceramic; and the diffuser is installed in a splicing manner, which can adjust the number of diffuser pipes according to the actual height of the drying room, so that the diffuser can better adapt to drying rooms of various heights, and improve the versatility of the diffuser;

[0034] The application discloses a ceramic product drying equipment.

[0035] Referring to Figure 1 and Figure 2 A ceramic product drying equipment comprises a fixed seat 12 fixed on the top of a drying room, a rotating rod 17 rotatably connected to the fixed seat 12, an air supply fan blade 6 mounted on the bottom of the rotating rod 17, a first driving member 1 in the form of a driving motor bolted to the fixed seat 12 and used for driving the rotating rod 17 to rotate, wherein the driving motor is located on the top of the rotating rod 17, a connecting collar 31 inserted into the rotating rod 17, locking grooves formed in the outer wall of the rotating rod 17, locking blocks integrally formed on the inner wall of the connecting collar 31 and matched with the locking grooves in clamping mode, and the connecting collar 31 rotatably connected to the driving motor.
