Development of New Dryer Lifting Plate Technology

The lifting plate plays a vital role in the dryer's work. Its shape, quantity, distribution, etc. all have a serious impact on the drying effect. Therefore, many times your material drying project is good or not, the lifting plate has said .

In 2015, the development of Zhengzhou Hongtai's new type of plate raising technology represented a new step in the application of dryers in China. From the equipment setting, program planning, to production, installation, commissioning and technical training, Hongtai Heavy Industry has performed one-handed operation. We will use the technology and experience we already have in our efforts to make the best use of user projects.

The internal multi-tube type material feeder is the dumping of the material as many times as possible for each rotation of the drum dryer drum. It is better that the material lifting plate can make the material evenly distributed over the entire cross section of the drum. With such a uniform distribution of the material, it can ensure good contact with the drying medium, increase the filling degree of the drum, and make the product and along the When the drum flows, the flue gas in the layer is strongly mixed, which makes the material dry better. For active material feeders, it is known that the stickiness of materials is a major obstacle to the drying effect. With the development of dryer technology and long-term use of experience, a variety of feeders have been recognized by customers in production applications.

Dryer activities Yang feeders are mainly divided into the following categories (Sales 13526601405):

The first type is to suspend a short chain ring on the lifting plate. When the cylinder rotates, the chain ring also rotates. When the lifting plate turns to the bottom, the short chain ring shrinks on the folding force surface of the lifting plate. The material that has fallen from above is covered on top of it, and this chain ring becomes the heating body of the material. When the dryer platen rotates to a certain height, the short chain ring suddenly pushes off the material and dangles in midair. At the same time, the lifting plate is also cleaned.

The second is an active lift device. This kind of lifting plate is of unequal bending type, with rotating shafts at both ends, and the shaft seat is fixed on the wall of the cylinder. When the material plate is at the bottom of the cylinder, it plays a certain role as a material. When it is randomly transferred to a certain height, the material plate is turned over and all the materials are scattered. When the board is overturned, it has a certain impact with the barrel, and the materials adhered to the board are also completely shaken.

The third type of movable lifting device is a kind of feather plate formed by flat steel processing. There is a certain gap between the flat steel. The upper end of the feather plate is fixed on the wall of the tube by hinges or screws and arranged in a staggered manner. . When the drum of the dryer rotates, the lower plumes will be tilted in order. When they turn to a certain height, the plumes open again and support the front pinch to lift the material. The plume plate of the dryer rises to the top near the top and it sags slowly, at which point the material also falls down. The advantage of this type of structure is that the mass can be sufficiently broken, and the feathered plate has the effect of cleaning each other.

The fourth is the dryer braided tube instead of the lifting plate. The advantage is that when the cylinder rotates, the braided tube also has a non-stopping motion of the rubbing so that the wet material does not easily adhere to it. At the same time, all the materials are floated in the space of the cylinder body, so that the thermal medium and the material are in full contact, thereby improving the drying efficiency of the material. The movable lifting plate is generally installed behind the guide plate. Because this type of lifting plate rotates and swings with the rotation of the cylinder, it can stir and crush the material. Therefore, it is particularly effective for materials that have already been agglomerated.

In the operation of Hongtai brand dryers, if the material has high moisture content, it is easy to form agglomerated materials at the feeding place, and then the movable lifting plate can be directly installed at the feeding port. At the same time, the material is crushed and broken up. The contact area of ​​raw materials and hot air. At the same time, in the process of rotating the dryer, the movable panel is often in contact with hot air and materials to exchange heat, thereby accelerating the drying process.
