Description

The feed structure of the hot air pipeline that improves the looseness of air-dried materials

technical field

The utility model relates to the technical field of tobacco processing, in particular to the tobacco airflow drying processing technology.

Background technique

The airflow drying process has the advantages of high drying intensity, short drying time, large processing capacity, high thermal efficiency, simple structure of the airflow drying tube, and easy maintenance. Because airflow drying has the above advantages, airflow drying is widely used in chemical, food, pharmaceutical and other industries.

At present, the air drying types commonly used in the domestic tobacco processing industry mainly include fluidized bed drying, air drying combined with tower tubes, straight tube drying, and inverted cone drying. A typical drying structure includes a feed air lock, and the outlet of the feed air lock communicates with the hot air duct.

These drying types are all through mixing the material with the air flow, the material enters the hot air pipeline after passing through the feed air lock, and the material gas mixture passes through the drying pipeline or the drying chamber to realize the drying of the material. During the movement of the material in the drying pipe or drying chamber with the airflow, the material will automatically find the path with the highest airflow velocity to gather and move forward, especially the leaf filaments are easy to entangle with each other and form a group, and the material is difficult to completely disperse during the drying process. The heat and mass transfer coefficient of the solid-gas mixture is small, and it is difficult to achieve the best drying effect.

Utility model content

The purpose of the utility model is to provide a hot air pipeline feeding structure which improves the looseness of air-dried materials.

In order to achieve the above purpose, the hot air pipeline feeding structure of the utility model that improves the looseness of the air-flow drying material includes a feeding air lock and a hot air pipeline, and the outlet of the feeding air lock is connected downward to the feeding port of a material looser At least two rake rollers are arranged in the material loosener, and the discharge port of the material loosener is connected with the hot air pipeline downward; the rake rollers are respectively connected with a power device through a transmission device.

There are two rake rollers, and the two rake rollers are arranged at intervals on the same horizontal line in the loosener and turn in opposite directions.

The two rake rollers are arranged symmetrically with respect to the axis of the looser.

The transmission device is a chain transmission device or a belt transmission device, and the power device is a motor.

The utility model has the advantages of simple structure, low cost and convenient manufacture and use. Because the rake roller can fully disperse the material, it avoids the phenomenon that the shredded tobacco is intertwined and difficult to disperse, which reduces the drying effect, and greatly improves the drying effect of the material.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Each arc-shaped arrow in Fig. 1 shows the rotation direction of the rotating member at each arc-shaped arrow. The direction indicated by the straight arrow in the hot air duct 4 in FIG. 1 is the flow direction of the hot air.

As shown in Figure 1, the hot air duct feeding structure of the utility model that improves the looseness of air-dried materials includes a feed air lock 1 and a hot air duct 4, and the discharge port 5 of the feed air lock is connected downward with a material loosener 2 The feed port 6 of the material looser is connected, and two rake rollers 7 are preferably provided in the material looser 2 (the housing) (of course, more than three rake rollers 7 can also be provided), and the discharge port 10 of the material looser is downward and The hot air pipes 4 communicate with each other; the raking rollers 7 are respectively connected with a power device 9 through a transmission device 8 .

The two rake rollers 7 are arranged at intervals on the same horizontal line in the looser and turn in opposite directions. The two rake rollers 7 are arranged symmetrically with respect to the axis 11 of the fluffer. The transmission device 8 is a chain transmission device or a belt transmission device, and the power device 9 is a motor.

The rotating speed of described two raking rollers 7 can be identical, and the preferred situation is that the rotating speeds of two raking rollers 7 are different, promptly preferred

Wherein the rotating speed of a raking roller is higher than the rotating speed of another raking roller, to improve the material loosening effect of raking roller 7. The range of the rotating speed of the two raking rollers is 30-80 rev/min.

When in use, the material falls down into the material loosener 2 through the discharge port 5 of the feed air lock, and when passing through the two rake rollers 7, the two rake rollers 7 that are turned to the opposite direction are fully dispersed during the rotation, and the dispersed The material falls down into the hot air duct 4 through the discharge port 10 of the material loosener, and is taken away by the hot air in the hot air duct 4 and dried.

Because the rake roller can fully disperse the material during rotation, it avoids the phenomenon that the shredded tobacco is intertwined and difficult to disperse, which reduces the drying effect, and greatly improves the drying effect of the material.

The above embodiments are only used to illustrate and not limit the technical solutions of the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present utility model shall fall within the scope of the claims of the present utility model.
