Abstract

The invention discloses a blow-drying device for a ceramic production process. The blow-drying device for the ceramic production process comprises a centrifugal fan, an impeller comprises a front disc, a rear disc and blades, the multiple blades are evenly distributed between the front disc and the rear disc in the circumferential direction, the inlet end of the front disc is provided with an arc-shaped inlet ring part, and the side, away from the blades, of the rear disc is provided with a back ring; and the blow-drying device is characterized in that the radial periphery of the arc-shaped inlet ring part is tightly connected with a first noise reduction ring, and the first noise reduction ring is a first metal foaming porous body. The noise reduction ring / metal foaming porous body is arranged at the inlet ring and / or the back ring of the impeller, the noise of the fan can be effectively reduced, the metal foaming porous body is arranged at the inlet ring and the back ring of the impeller, compared with other noise reduction structures, the better noise reduction effect is achieved, the better heat dissipation / heat transfer effect is achieved, and therefore, the blow-drying effect is improved.

Description

technical field

[0001] The invention relates to the technical field of ceramic production and manufacturing technology, in particular to a drying device used in the ceramic production technology. Background technique

[0002] In the manufacturing process of ceramic products, drying treatment is required after wetting or cooling, and ventilation devices are often used for drying treatment, and the performance of ventilation devices seriously affects the effect of drying treatment.

[0003] The centrifugal fan of the existing ventilation device, the centrifugal fan includes an impeller and a volute. Between the front disk and the rear disk, the inlet end of the front disk has an arc-shaped inlet ring, and the side of the rear disk away from the blades is provided with a back ring. However, the existing ventilation device / centrifugal fan has the problems of high noise and unadjustable noise reduction effect. Contents of the invention
