In said structure, because described steam heater is provided with the condensed water collecting pipe, the condensed water with higher temperature that produces in the steam heater course of work just can collect; Again because described main drier outer wall is provided with container, this container and described condensed water collecting pipe lead to by piping installation, the collected high-temperature condensation water of condensed water collecting pipe just can be passed in the container on the main drier outer wall by piping installation like this, because collected condensed water itself has the above temperature of 85 degree, after it arrives in the container on the main drier outer wall, just can heat to the material in the main drier by main drier outer wall, and can intercept temperature higher in the main drier to external diffusion, make waste heat obtain effective utilization, save the energy, also improved the efficient of dry materials simultaneously.
A kind of preferred embodiment of the present utility model, described main drier is pneumatic conveyer dryer.Owing to adopt pneumatic conveyer dryer as main drier; and pneumatic conveyer dryer is to utilize swiftly flowing thermal current that wet fine grained or granular material are suspended in wherein, carries out drying in the air current flow process, has the heat transfer coefficient height; characteristics such as heat transfer area is big, and drying time is short.So drying effect is comparatively desirable concerning the haloflex product of fine particulate, can obtain drying effect preferably.
Another kind of preferred embodiment of the present utility model, described container is the jacket water tank around main drier outer wall.This embodiment structure is simple relatively, and the condensation hot water that utilizes can heat main drier around the outer wall of main drier.
Further preferred embodiment of the present utility model, described container is the helix water pipe structure around main drier outer wall.Adopt this structure that condensation heat water is heated along the helix water pipe around main drier outer wall, heating is evenly distributed, and effect is better.
Another preferred embodiment of the utility model, described piping installation is by hot water collecting box, heat-exchanger pump and lead at the water inlet pipe of described container bottom and the outlet pipe that leads on described container top and constitute, described hot water collecting box and condensed water collecting pipe lead to, described water inlet pipe leads to by heat-exchanger pump and hot water collecting box, and described outlet pipe and hot water collecting box lead to.Adopt this mode, can guarantee that condensation hot water effectively collects and utilize heat-exchanger pump to be transported in the needed container, the hot water that still has uniform temperature that the container outlet pipe can also be come out is collected the use of remaining valid in the hot water collecting box.
The another further preferred embodiment of the utility model, described container, hot water collecting box, water inlet pipe, outlet pipe are coated with heat-insulation layer.Adopt this mode, can prevent the loss of heat better, reach further energy-saving effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments a kind of energy-saving material drying device of the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of a kind of energy-saving material drying device of the utility model
Among the figure: 1-piping installation, 101-outlet pipe, 102-heat-exchanger pump, 103-hot water collecting box, 104-water inlet pipe, 2-condensed water collecting pipe, 3-container, 4-steam heater, 5-warm-air pipe, 6-master's drier, 7-charging aperture, 8-cyclone separator, 9-air-introduced machine.
The specific embodiment
Main drier 6 is pneumatic conveyer dryer in a kind of energy-saving material drying device shown in Figure 1, it leads to cyclone separator 8, air-introduced machine 9 from top successively by conveyance conduit, the outer wall at main drier middle part is provided with container 3, this container 3 is the jacket water tank around main drier 6 outer walls, bottom at main drier 6, lead to warm-air pipe 5 and charging aperture 7 are arranged, warm-air pipe 5 is provided with steam heater 4, described steam heater 4 is provided with condensed water collecting pipe 2, and this condensed water collecting pipe 2 leads to by piping installation 1 and container 3; Described piping installation 1 is by hot water collecting box 103, heat-exchanger pump 102 and lead at the water inlet pipe 104 of described container 3 bottoms and the outlet pipe 101 that leads on described container 3 tops and constitute, described hot water collecting box 103 leads to condensed water collecting pipe 2, described water inlet pipe 104 leads to by heat-exchanger pump 102 and hot water collecting box, and described outlet pipe 101 leads to hot water collecting box 103.Described container 3, hot water collecting box 103, water inlet pipe 104, outlet pipe 101 are coated with the heat-insulation layer (not shown).
