Abstract

The utility model relates to a drying device for a hot air stenter, which comprises a drying box, a blower, a heater, an exhaust fan and a negative pressure box. The air outlet is connected, a heater is installed on the air inlet pipe, and a plurality of hollow cloth guide rollers arranged at intervals and alternately arranged in order are arranged in the drying box. The hollow cloth guide rollers are connected with the hot air chamber through the connecting pipe. An exhaust pipe is arranged on the side, a negative pressure box is arranged downstream of the drying box, and an exhaust fan is arranged on the negative pressure box, and the exhaust fan is connected with the negative pressure box through the exhaust pipe; When blowing hot air, since the hollow fabric guide roller is in contact with the fabric, the heat utilization efficiency is higher, and the drying efficiency is improved. The remaining small amount of moisture on the fabric is further evaporated under the negative pressure in the negative pressure box, and the drying is thorough.

Description

A drying device for a hot air stenter

technical field

The utility model relates to the technical field of textile equipment, in particular to a drying device for a hot air tenter.

Background technique

In the existing hot air stenter, the moisture contained in the cloth is dried by the hot air device. It has a drying box for the cloth to pass through, and a hot air circulation device is installed in the drying box. Dry the cloth. After drying, the gas with a lot of heat is discharged. During this process, the drying efficiency is low, and the drying effect is not good, which seriously affects the product quality.

Utility model content

What the utility model intends to provide is a drying device for a hot air tenter.

In order to solve the above technical problems, the utility model provides the following technical solutions: a drying device for a hot air stenter, including a drying box, a blower, a heater, an exhaust fan and a negative pressure box, and the inner wall of the drying box is provided with a hot air The hot air chamber is connected to the air outlet of the blower through the air inlet pipe. A heater is installed on the air inlet pipe, and a plurality of hollow cloth guide rollers arranged at intervals and alternately arranged in sequence are arranged in the drying box. The hollow cloth guide rollers are connected through the The pipe is connected with the hot air chamber, the side of the drying box is provided with an exhaust pipe, the downstream of the drying box is provided with a negative pressure box, and an exhaust fan is arranged on the negative pressure box, and the exhaust fan is connected with the negative pressure box through the exhaust pipe.

In a further optimized solution, an air filter is arranged on the exhaust pipe.

In a further optimized solution, a water-absorbing layer is arranged on the inner wall of the negative pressure box.

Compared with the prior art, the utility model has the beneficial effects that: the utility model directly blows hot air to the cloth through the hollow cloth guide roller, and since the hollow cloth guide roller and the cloth offset each other, the heat utilization efficiency is higher, and the drying efficiency is improved. The remaining small amount of moisture on the fabric is further evaporated in the negative pressure state in the negative pressure box, and the drying is thorough.
