Abstract
The utility model discloses a drying cylinder for paper making, which comprises a cylinder body, wherein one side of the cylinder body is connected with a heat-conducting oil pipe and an oil discharge pipe sleeved in the heat-conducting oil pipe to the inside of the cylinder body from the inside of a rotating shaft; and in the cylinder body, oil distributing pipes are arranged in the heat-conducting oil pipe along the radial direction, the oil discharge pipe is downwards arranged, and transversely arranged fins are uniformly arranged along the cylindrical inner wall of the cylinder body. Because heat-conducting oil is adopted as medium-drying wet paper in the utility model, the temperature thereof can reach 320 DEG C, the cylinder wall of the drying cylinder can be heated to the temperature of 180 DEG C, and the rotating speed of the drying cylinder can reach 15 revolutions per minute. Superheated steam is adopted as a heating medium, the temperature thereof is not more than 150 DEG C, the cylinder wall of the drying cylinder only can be heated to the temperature of 135 DEG C, and the rotating speed of the drying cylinder is 10 revolutions per minute. The utility model can markedly improve the energy utilization ratio and the production efficiency when being compared.
Description
Technical field
The utility model belongs to paper making equipment, is specifically related to a kind of drying cylinder that is used for papermaking.
Background technology
In paper technology, to use usually drying cylinder will through the squeezing after l Water Paper (moisture is up to 52-70%) drying.Drying cylinder is a cylindrical shell cylindraceous, and cylindrical shell one side is connected to steam pipe and drainpipe in rotating shaft, utilizes superheated steam to feed in the cylinder as medium the cylinder barrel wall is heated, and makes attached to the l Water Paper drying on the drum surface, and cooled steam condenses into water and discharged by drainpipe.Tradition paper-making drying cylinder equipment exist energy utilization rate low, produce the not high problem of efficient.
The utility model content
Problem to be solved in the utility model provides a kind of drying cylinder that is used for papermaking that can improve energy utilization rate and production efficiency.
The technical scheme that its technical problem that solves the utility model adopts is:
The drying cylinder that is used for papermaking comprises a cylindrical shell, and described cylindrical shell one side is connected to heat-conducting oil pipes and is enclosed within oil exit pipe the heat-conducting oil pipes to cylindrical shell in rotating shaft; In the cylindrical shell, heat-conducting oil pipes radially is provided with the cloth oil pipe, and oil exit pipe is provided with downwards, evenly is provided with horizontal fin along the cylinder inner wall of cylindrical shell.
Described cloth oil pipe has a plurality of downward-sloping side by side settings.
The drying cylinder that adopts said structure with conduction oil as heat medium, conduction oil is entered in the drying cylinder by heat-conducting oil pipes, be delivered to the cylinder inner wall that rotates middle cylinder body from the cloth oil pipe, barrel is heated the l Water Paper drying that makes attached to cylinder outer wall, the conduction oil that loses heat accumulates in the cylindrical shell bottom, fin on the cylinder inner wall constantly mixes the conduction oil of fresh thermal conductance deep fat and cooling in the cylindrical shell rotation process, makes that barrel preheating through the bottom time is even, guarantees the l Water Paper homogeneous heating that cylinder is outer.Cooled conduction oil is evacuated to hot oil boiler recirculation heating by oil exit pipe.The cloth oil pipe adopts a plurality of downward-sloping side by side settings that the thermal conductance deep fat is evenly distributed on barrel.
The utility model is owing to adopt conduction oil as the dry l Water Paper of medium, and its temperature can reach 320 ℃, and the drying cylinder barrel can be heated to 180 ℃, and drying cylinder changes 15 rev/mins of scooters.Heat medium adopts superheated steam, and its temperature is not more than 150 ℃, and the drying cylinder barrel can only be heated to 135 ℃, and the drying cylinder rotating speed is 10 rev/mins.Two compare, and the utility model can significantly improve energy utilization rate and production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
As shown in Figure 1 and Figure 2, the drying cylinder that is used for papermaking comprises a cylindrical shell 1, and described cylindrical shell 1 one sides are connected to heat-conducting oil pipes 2 and are enclosed within oil exit pipe 3 heat-conducting oil pipes 2 to cylindrical shell 1 in rotating shaft 7; In the cylindrical shell 1, heat-conducting oil pipes 2 is radially downward-sloping side by side to be provided with two cloth oil pipes 4, and oil exit pipe 3 is provided with downwards, evenly is provided with horizontal fin 5 along the cylinder inner wall of cylindrical shell 1.
Operation principle:
Drying cylinder rotates in the direction of arrows, fresh thermal conductance deep fat is entered in the cylindrical shell 1 by heat-conducting oil pipes 2, being distributed to cylinder inner wall through cloth oil pipe 4 heats cylindrical wall, make the l Water Paper drying on the cylinder outer wall, fin 5 on the cylinder inner wall constantly mixes the conduction oil 6 of fresh thermal conductance deep fat and cooling in cylindrical shell 1 rotation process, make that barrel preheating through the bottom time is even, guarantee the l Water Paper homogeneous heating that cylinder is outer.Cooled conduction oil 6 is evacuated to hot oil boiler recirculation heating by oil exit pipe 3.
Claims (2)
1. a drying cylinder that is used for papermaking comprises a cylindrical shell, it is characterized in that described cylindrical shell one side is connected to heat-conducting oil pipes and is enclosed within oil exit pipe the heat-conducting oil pipes to cylindrical shell in rotating shaft; In the cylindrical shell, heat-conducting oil pipes radially is provided with the cloth oil pipe, and oil exit pipe is provided with downwards, evenly is provided with horizontal fin along the cylinder inner wall of cylindrical shell.
