Description

Technical Field

[0001] The utility model relates to the technical field of non-alkali glass fiber cloth production, and particularly relates to a drying device for producing non-alkali glass fiber cloth. Background Technique

[0002] Nowadays, the demand for non-alkali glass fiber cloth is gradually increasing. It has the function of waterproofing, but water droplets will accompany its surface during production, and it needs to be dried before it is convenient for storage and transportation. The drying of non-alkali glass fiber cloth is an important link in the production process of glass fiber, which directly affects the quality and subsequent processing performance of the glass fiber cloth;

[0003] Chinese Patent Authorization Publication No. CN218001996U discloses a drying device for glass fiber cloth, including a main body, a glass fiber cloth, and an air drying component arranged inside the main body for drying the glass fiber cloth. A drying chamber is opened inside the main body, and a chamber door is rotatably connected to the front of the drying chamber through a hinge. This drying device diverts the airflow through the air outlet pipe to dry the glass fiber cloth from the inside, avoiding the situation that the inside of the glass fiber cloth is difficult to be blown by the airflow and thus difficult to be properly dried. At the same time, the heat on the heating wire is conducted to the support rod by heating the water in the heating chamber. The heat transfer by water with a large specific heat capacity can improve the uniformity of heat conduction and avoid the situation of overheating and burning due to heat accumulation in a certain place;

[0004] The above-mentioned prior art solutions have the following deficiencies: During the use of this drying device, most of the water vapor will pass through the exhaust window to the outside, making it difficult to keep the temperature inside the drying chamber rising, which will prolong the drying time and reduce the drying efficiency. There is room for improvement in the vapor treatment aspect. Therefore, it is necessary to design a drying device for producing non-alkali glass fiber cloth to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drying device for producing non-alkali glass fiber cloth to solve the problem that the direct passage of water vapor through the exhaust window to the outside will prolong the drying time mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A drying device for producing alkali-free fiberglass cloth, including a drying box. On both sides inside the drying box, there are guide rollers rotatably connected. At one end of the drying box, there is a hot air delivery box, and on one side of the air outlet of the hot air delivery box, there is a shunt pipe connected. At the top of the drying box, there is a steam treatment box fixed, and the intake port inside the steam treatment box and the exhaust port inside the drying box are in the same vertical plane. Inside the steam treatment box, there is an electric fan fixedly connected, and the electric fan is directly above the intake port inside the steam treatment box. On both sides inside the steam treatment box, there are respectively a filter screen frame and a mounting frame snap-fitted. Inside the mounting frame, there is a desiccant packet filled. On the outer surface of the steam treatment box away from the electric fan, there is a connecting pipe connected, and the connecting pipe extends into the inside of the drying box.

[0007] Preferably, at the top of the electric fan, there is a speed reducer, and at the top of the speed reducer, there is a rotating shaft fixedly connected. On the outer side of the rotating shaft, there are six stirring blades connected, and the stirring blades are arranged in a circumferential array on the outer side of the rotating shaft.

[0008] Preferably, at the top of the rotating shaft, there is a connecting block fixedly connected. Inside the steam treatment box, there is a connecting groove arranged, and the connecting groove is rotatably connected with the connecting block.

[0009] Preferably, at the top inside the drying box, there is an electric telescopic rod, and at the output end of the electric telescopic rod, there is a partition plate connected by bolts. The partition plate is adapted to the size of the exhaust port of the drying box.

[0010] Preferably, at both ends inside the drying box, there are air delivery channels arranged. The inside of the shunt pipe is connected to the inside of the air delivery channels. At both ends of the inner wall of the drying box, there are mounting sleeves rotatably connected. At both ends of the mounting sleeve, there are respectively a guide air pipe and an extension pipe fixedly connected. The guide air pipe and the extension pipe are in a communicating state. The extension pipes all extend into the inside of the air delivery channels. On the outer side of the guide air pipes, there are three groups of air delivery heads fixedly connected. Each group of air delivery heads has four, and the air delivery heads are arranged in a cross-shaped distribution on the outer side of the guide air pipe.

[0011] Preferably, at both ends inside the drying box, there are motors arranged, and the output shafts of the motors are all connected with gears. The gears are all meshed with the teeth on the outer side of the mounting sleeve.

[0012] Preferably, at one end of the mounting sleeve close to the drying box, there are rotating rings fixedly connected. At both ends inside the drying box, there are rotating grooves opened, and the rotating grooves are rotatably connected with the rotating rings.

[0013] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0014] The exhaust port is closed by an electric telescopic rod and a partition to accelerate the heating speed inside the drying box. Through the electric fan, reducer and stirring blades, the steam is pushed to one side of the stirring blades inside the steam treatment box. The steam is filtered and dried by the stirring blades and the filter screen frame.
