Benefits of technology
This new design allows for better control over both the temperature within the chamber during operation and how well it works when delivering high pressure gas or liquid at specific points along its path. It also includes features like eccentrically positionable drums and lamps attached to an insulated jacket made of metal tubes filled with oil instead of air, which helps prevent damage caused by friction. Overall, this technology makes materials easier to break down and dried effectively without causing any issues such as unevenness or bending under heavy loads.
Problems solved by technology
This patented technology describes different ways to make dried materials more efficient while reducing costs compared to traditional methods like rolling them out onto racks. However, current systems have limitations such as requiring long dry times due to poor consistency caused by uneven temperature distribution across the entire surface area inside the rolls being treated, difficulty maintaining accurate alignment within each layer without causing instability or excessive power usage, difficulties connecting pipes to the internal walls of the roll's interior, issues related to improving thermal management, etc., making these techniques challenged from an industrial perspective.

Embodiment 1
[0036] Embodiment one, see Figure 1-16 , a double-cylinder inner wall heat exchange type steam dryer, including a bottom frame, an inner layer drum and an outer layer drum coaxially installed on the bottom frame, a central rotating shaft coaxially installed in the inner layer drum, and a central rotating shaft installed on the same The steam rotary joint at the end and the rotating ventilation hoop, and the driving device for driving the drum to rotate;
[0037] Both the inner layer drum and the outer layer drum are cylindrical, and the inner layer drum is coaxially set inside the outer layer drum and fixed by long bolts arranged along the circumferential direction, and the long bolts are arranged along the diameter of the inner layer drum. It runs through the inner drum body and the outer drum body outwards in turn, and is tightened by the nuts outside the outer drum. The outer and inner peripheral surfaces of the inner drum are provided with a number of holes evenly arrange...

The invention relates to a double-cylinder inner wall heat exchange type steam dryer. The double-cylinder inner wall heat exchange type steam dryer comprises a bottom frame, an inner-layer roller, an outer-layer roller, a center rotating shaft, a steam rotating joint, a rotating ventilation hoop and a driving device, wherein the inner-layer roller and the outer-layer roller are coaxially installed on the bottom frame, the center rotating shaft is coaxially installed in the inner-layer roller, the steam rotating joint and the rotating ventilation hoop are installed at the same end of the center rotating shaft, and the driving device drives the rollers to rotate. According to the double-cylinder inner wall heat exchange type steam dryer, firstly, the inner-layer roller and the outer-layer roller are fixed through long bolts, so that installation and adjustment are convenient, the concentricity problem between the inner-layer roller and the outer-layer roller is improved to a certain extent, and the whole equipment is more stable in operation; secondly, a beating hammer and crushing ribs are arranged inside the inner-layer roller, so that wet and sticky materials are fully scattered and are convenient to dry, the beating hammer continuously beats the roller wall along with the rotation of the inner-layer roller, so that the materials adhered to the roller wall are separated from the beating hammer, and the drying quality is guaranteed; and thirdly, the inlet end and the outlet end of drying steam of the whole dryer are both concentrated at one end of the center rotating shaft, so that installation and concentrated collection of condensate water are facilitated.
