Description

Material steam preheating device

Technical Field

The utility model relates to a material steam preheating device, and belongs to the field of chemical industry.

Background

In chemical production, certain barreled or canned materials are viscous and poor in fluidity at low temperature, and can be smoothly conveyed only by preheating during feeding. The steam drying room is a mode that large quantities of barreled materials are preheated economically, materials are heated by heat exchange through the steam exhaust pipes, and the steam drying room is widely applied to chemical enterprises at present.

Among the prior art, the steam calandria of steam baking house is mainly laid in the wall of baking house, through hot-air convection heating barreled material, and the not enough of this kind of structure baking house mainly has: firstly, the steam calandria lays with high costs, and secondly, the rate of heating is slow, and especially the barrel head part heats slowly, forms hot-top and cold-bottom phenomenon, is unfavorable for the output of barrel head part material.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects, the utility model provides a material steam preheating device, which adopts the technical scheme that:

a material steam preheating device comprises a drying room with a heat insulation layer, wherein hollow support bars with trapezoidal sections are continuously distributed on a bottom plate of the drying room, and a heat conduction plate is laid on the support bars; the side edges of the adjacent supporting bars and the lower end surface of the heat conducting plate form steam channels, and one end of each adjacent steam channel is communicated to enable all the steam channels to form a continuous snake-tube-shaped or bow-shaped channel; the steam channel positioned at the outermost side of the bottom plate is respectively connected with a steam inlet joint and a steam condensate water outlet joint.

Furthermore, a plurality of vent holes are formed in the upper end face of the supporting bar at intervals, and corresponding through holes are formed in the positions, corresponding to the vent holes, of the heat conduction plate.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the heating effect of the bottom material can be improved by adopting a steam heating mode at the bottom of the drying room, and meanwhile, the heating efficiency of the material can be improved by direct heat conduction between the heat conduction plate and the material barrel and heat convection of air in the drying room, so that the preheating effect of the material is ensured.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.

Example (b):

referring to fig. 1-2, a material steam preheating device comprises a drying room 100 with a heat insulation layer, wherein hollow support bars 20 with trapezoidal cross sections are continuously arranged on a bottom plate 10 of the drying room 100, and heat conduction plates 30 are laid on the support bars 20; the side edges of the adjacent supporting bars 20 and the lower end surface of the heat conducting plate 30 form steam channels 40, and one end of each adjacent steam channel 40 is communicated, so that all the steam channels form a continuous arch-shaped channel; the steam channel 40 located at the outermost side of the soleplate 10 is respectively connected with a steam inlet joint 50 and a steam condensate water outlet joint 60.

Furthermore, a plurality of vent holes 70 are formed in the upper end surface of the support bar 20 at intervals, and corresponding through holes 80 are formed in the heat conducting plate 30 at positions corresponding to the vent holes 70.

When preheating the barreled material, put the barreled material on the heat-conducting plate, the outside steam source inserts the steam way from steam admission joint, and steam preheats the barreled material to the heat-conducting plate heating rethread thermal conduction and thermal convection, can guarantee the heating effect of barreled material bottom material. Meanwhile, hot air in the hollow support bar exchanges heat with air in the drying room body through the vent holes and the through holes in the heat conducting plate, and low-temperature steam and condensed water in the steam channel are discharged through the steam condensed water outer discharge joint.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
