Abstract

The utility model relates to a water flow cycling and heat transferring drying device. The water flow cycling and heat transferring drying device comprises pipelines and a shelf. The water flow cycling and heat transferring drying device is characterized in that the pipelines comprise a water inlet pipeline, a reflowing pipeline and shelf pipelines, wherein the two ends of the shelf pipelines are communicated with the water inlet pipeline and the reflowing pipeline and are wound to form a shelf structure; supporting beams are fixedly arranged on the lower sides of the shelf pipelines. According to the water flow cycling and heat transferring drying device, objects placed on the shelf can be dried by using radiation heat of flowing hot water in the shelf pipelines. Compared with hot air drying, the water flow cycling and heat transferring drying device has the advantages that firstly, energy source waste caused by the discharging of high-heat wet gas can be reduced greatly; secondly, the objects are heated by radiation and are dried so that the outsides and the insides of the objects are dry; thirdly, the water flow cycling and heat transferring drying device is suitable for drying thick objects. The water flow cycling and heat transferring drying device can be widely applied to drying marine products and is also applicable to drying processed foods including extra-thin noodles and the like.

Description

Water circulation heat transfer drying unit

Technical field:

The utility model belongs to field, and particularly a kind of water circulation heat transfer drying unit, especially be applicable to the oven dry of agricultural byproducts.

Background technology:

All the time, the most of agricultural byproducts of China, as cereal etc., be all to utilize the sunlight heat dryness in the sun, if but meet continuously overcast and rainyly, usually cause gathered agricultural byproducts mouldy even rotten.In order to reduce the loss, some burn bavin or charcoal direct baking agricultural byproducts, this easy method thermal efficiency is extremely low, in flue gas 3,4 benzo castors are seriously polluted, affect product quality, some cure with the large iron pan of cooking, and the iron pan of the cross section arc concentrated the bottom of a pan that is heated, usually burn institute's dry products.In order to solve this dry technology problem, domestic related scientific research technical staff designs blowing hot-air dry technology device, the oven dry agricultural byproducts device of existing domestic use, all with fuel heating of metal inside pipe wall or outer wall, in the outer or pipe of cold wind flow path pipe and heated, use hot blast to be blowed to dried agricultural byproducts it is dehydrated.This blowing hot-air furnace drying method thermal efficiency is low.The high temperature section pipeline after by flame combustion yielding and burning oxidized metal outer tube layer come off successively and bore a hole, service life is short, within every 2 to 4 years, will upgrade cooking stove.The blowing hot-air drying, no matter be from bottom to top or from left to right, still blow from bottom to top with from top to bottom simultaneously, heat supply all is difficult to accomplish evenly, the agricultural byproducts drying that the multilayer high-moisture percentage is stacked all can cause the larger gradation of moisture and thermograde, be emitted on each layer of product on the baking sieve and the dry wet drawback differed all can occur, for dry wetting phase to unification, improve the thermal efficiency, need artificial upset layer frame, put into successively new material, cause so the omnidistance oven dry cycle long, the labour wastes many, breakage rate is high, the blowing hot-air drying can not be according to the many of institute's material drying with few, flexible modulation blowing heat supply spatial volume, material can not be booked in the situation of each layer of baking sieve, can cause heat energy waste in various degree, the blowing hot-air drying, to the more difficult adjusting of required bake out temperature.The hot-air seasoning method, for thicker agricultural byproducts, be difficult to accomplish the same outside and inside, and surperficial too fast syneresis often, affect the internal moisture evaporation.

The thermal source aspect, use the shell and tube stove, pipe ends leakiness cigarette, unstable properties, affect the dries quantity of agricultural byproducts, use three return hot-blast stoves, because body of heater is the monoblock type metal structure, can not keep in repair or change parts, adopt sprocket wheel electric adjustable bed device, push away operation although abandoned manually to turn over, the concrete operations difficulty is large.

Summary of the invention:

The purpose of this utility model is that design is a kind of by the water circulation heat transfer drying unit of hot water circulation heated baking zone frame.

Technical solutions of the utility model are achieved in that a kind of water circulation heat transfer drying unit, comprise pipeline and layer frame, it is characterized in that pipeline is divided into inlet channel, reflux line and layer frame pipeline; Layer frame pipe ends is communicated with inlet channel and reflux line, and the stratification shelf structure that spirals, and at layer frame pipeline downside, is fixed with brace summer.Utilize in layer frame pipeline the radiations heat energy of the hot water that flows, the article that are placed on layer frame are dried.

Described layer frame pipeline at least is provided with two, and two layer frame pipelines are parallel distributed uniformly-spaced, and the water (flow) direction of adjacent layer frame pipeline is contrary.More even to guarantee the radiations heat energy on layer frame.

The brace summer of described layer frame pipeline downside is metal material.Improve heat conduction and photothermal generation.

Described layer frame top is shelved with the heat-conducting type drying tray.Being beneficial to heat evenly passes to by drying article.

It is fuel that the utility model can utilize coal, bavin, oil, crop straw etc., and water is constantly heated, and allows water by the pipeline continuous heat release that circulates simultaneously, and specific heat of water is large, and the thermal efficiency is high, clean heat supply; Also can utilize GEOTHERMAL WATER, industrial heat treated water directly or continue after heat temperature raising for drying fuel saving; Again utilize after waste heat water centralized recovery, reduce fuel cost, adopt the parallel reverse circulation of twin flue to conduct heat, heat supply is even, does not need upset layer frame, saves the labour; Compare hot-air seasoning, one can greatly reduce high hot moisture exhausting, the energy waste caused; It two is by the radiation heating article, makes its oven dry, reaches the same outside and inside; The oven dry of its three very applicable thicker article.Can be widely used in the oven dry of marine product, also be applicable to the oven dry such as processed foods such as line faces.

The accompanying drawing explanation:

Below in conjunction with concrete legend, the utility model is described further:

Wherein

1-inlet channel, 2-reflux line 3-layer frame pipeline 4-brace summer

5-drying tray

The specific embodiment:

See figures.1.and.2, water circulation heat transfer drying unit, comprise pipeline and layer frame, and pipeline is divided into inlet channel 1, reflux line 2 and layer frame pipeline 3; Layer frame pipeline 3 two ends are communicated with inlet channel 1 and reflux line 2, and the stratification shelf structure that spirals, and at layer frame pipeline 3 downsides, are fixed with brace summer 4, in order to fixed bed frame pipeline 3, and the planarization of retaining layer frame; This brace summer 4 is metal material, to improve heat radiation; Be shelved with heat-conducting type drying tray 5 above layer frame, this drying tray 5 is used for holding article to be dried, both has been conducive to evenly heat conduction, also is convenient to the article drying operation.Drying tray 5 can be engraved structure, also can directly adopt metal dish.

Described layer frame pipeline 3 at least is provided with two, two layer frame pipelines 3 are parallel distributed uniformly-spaced, the water (flow) direction of adjacent layer frame pipeline 3 is contrary, consider layer thermal-radiating loss of frame pipeline 3, be communicated with an end with inlet channel 1 and with reflux line 2, be communicated with an end, it is high that temperature is wanted, two layer frame pipeline water flow opposite directions, just affect temperature difference complementation, the temperature that reaches any place is suitable.
