Description

Ceramic body drying room structure

technical field

The utility model relates to the technical field of ceramic production equipment, in particular to a drying room structure for a ceramic green body.

Background technique

The ceramic body is usually placed in a drying room for drying. The drying methods of the drying room include ordinary hot air drying, humidified hot air drying, microwave heating drying and electric heating drying.

At present, the drying room with humidified hot air drying is widely used. The hot air conduction of the humidified hot air drying adopts the wind cone rotation method. In order to ensure uniform temperature in the drying room, the wind speed of the air cone is relatively high, reaching 8 m/s, resulting in a large difference in drying speed between the inner and outer layers of the product body near the air cone, which may easily lead to increased cracking of the product due to uneven shrinkage of the inner and outer layers of the body. The humidification system of humidification and hot air drying adopts water high-pressure nozzle atomization, and the system needs to be equipped with a water booster system. In order to prevent the water atomization nozzle from filling, a water purification system is also equipped. The equipment investment cost is high, and the nozzles of this system are prone to dripping water due to scaling of the water pipeline.

There are multiple circulating air outlets; the air outlet pipe section is distributed at the bottom of the inner cavity of the room body; the inner cavity of the room body is also provided with a centrifugal humidifier, and the centrifugal humidifier is connected with a humidification air pipe. The humidification air duct is located on the upper part of both sides of the inner cavity of the room, and multiple humidification outlets are opened on the humidification air duct; the top of the inner cavity of the room body is also provided with a plurality of fans.

Preferably, the fans are distributed in two rows at the top of the inner cavity of the housing body.

Preferably, there are two centrifugal humidifiers and two humidifying air ducts.

Preferably, the circulating fan is connected with two circulating air pipes.

Preferably, an exhaust device is also provided in the room, and the air outlet of the exhaust device extends to the outside of the room.

The positive progress effect of the utility model is that: the hot air generated by the hot air system of the utility model enters the drying room through the circulating air duct, and then conducts heat conduction through the fan, and the hot air conduction mode is changed from the existing horizontal conduction mode to the up and down conduction mode, so that The difference in drying speed between the inner and outer layers of the product body in the drying room is very small, which makes the inner and outer layers of the product body shrink evenly, and reduces the cracking caused by uneven shrinkage of the product body. Using a centrifugal humidifier for humidification also achieves the atomization performance of the nozzle, cancels the traditional water pressurization and water purification system, and reduces equipment investment costs. At the same time, water dripping from the nozzle due to fouling of the water pipeline can also be avoided. Using the drying room to dry the ceramic green body can reduce the cracking by 3% in the drying stage of the drying room; at the same time, the manufacturing cost of the drying room is low, and its manufacturing cost is only 50% of similar products.

The hot air generating system 20 includes a circulating fan 30 and an air inlet 40 , and the air inlet 40 is located at the top of the inner cavity of the room body 10 .

The circulating fan 30 is connected with two circulating air ducts 50 . Each circulating air pipe 50 includes an air supply pipe section 51 connected to the circulating fan 30 and an air outlet pipe section 52 connected to the air supply pipe section 51 , and a plurality of circulating air outlets 53 are opened on the air outlet pipe section 52 . The air outlet pipe section 52 is distributed at the bottom of the inner cavity of the room body 10 .
