Abstract

The utility model relates to a drying machine, which is suitable for drying materials through steam heating. The machine is mainly composed of a steam jet pump, a jacket and a drying chamber, wherein, the air suction end of the steam jet pump is connected with the air suction pipe of the drying chamber; the air discharge end of the steam jet pump is connected with an air inlet connecting pipe on the jacket. After steam with high temperature and pressure is squirted by the steam jet pump, vacuum function can be generated; second steam generated by the evaporation of the materials in the drying chamber can be completely pumped into the jacket as heating medium; the purpose of complete effect drying can be realized. Compared with an existing congener drying machine, the utility model has the advantages of high thermal efficiency, quick drying speed, low cost, etc.

Description

Drying machine

The utility model relates to a kind of drying machinery with heating means drying solid material or goods.Specifically a kind of drier.

Drying machinery is widely used in each departments such as chemical industry, medicine, light industry, food, is important unit operating equipment.Existing drying machine is of a great variety, as spray-drying, fluidized bed drying, pneumatic conveying drying, tunnel type drying, revolving drum and vacuum drum drying etc.The thermal efficiency of above-mentioned all drying machines all can not reach 100%; At present, pneumatic conveying drying generally can only reach 40～50%, and the Steam Heating drying is the highest by only about 80%; The limitation of Here it is existing drying device.

So, may the thermal efficiency of drying machine surpass so-called 100%? in other words, can per kilogram steam dry moisture content more than one kilogram? concerning steam heated drying machine, answer should be sure; The example of tool convincingness is exactly: multi-effect evaporator, per kilogram steam can steam several kilograms of fresh water.Therefore, being necessary to redefine existing drying machine is: single-action drying machine (not reuse indirect steam); And can accomplish that the drying machine of fully recovering is defined as: drier to the indirect steam that the material that is dried evaporates.

The purpose of this utility model is: it provides a kind of device and flow process of drier; Can overcome the existing still unfavorable drawback of the steam heated drying machine thermal efficiency, reach the complete dry energy-conservation purpose of imitating.

In order to achieve the above object, the technical scheme that the utility model adopted is: it mainly is made up of steam jet pump, chuck and hothouse three big parts.High temperature and high pressure steam produces vacuum action after steam jet pump sprays, with the indirect steam that material evaporation in the hothouse produces, it is interior as heat medium all to be extracted into chuck, thereby can realize imitating full the purpose of drying.

Below in conjunction with accompanying drawing,, provide details of the present utility model by description to embodiment.

Accompanying drawing 1 is the utility model structural representation.

In the accompanying drawing: 1. blow-off pipe 2. core pipes 3. cut with scissors imperial coil pipe

4. hothouse 5. chucks 6. screw feeders

7. air inlet tube 8. exhaust tubes 9. steam jet pumps

10. rotation air inlet pipe 11. is rotated blow-off pipes 12. auger strippers

Shown in figure one: it comprises steam jet pump; Chuck, the face of cylinder one side of chuck is equipped with air inlet tube, and blow-off pipe is housed on the opposite side; Hothouse, hothouse one end is equipped with screw feeder, and the other end is equipped with auger stripper, on the face of cylinder one side of hothouse exhaust tube is housed also; The hinge dragon coil pipe that in the hothouse stamen pipe is housed also and joins with it, stamen pipe and the imperial coil pipe of hinge can be driven in rotation; High temperature and high pressure steam by a to entering steam jet pump, the moisture content of evaporation in the hothouse, through exhaust tube by c to entering steam jet pump, to space in air inlet tube enters chuck, walked along guide d by blow-off pipe by condensed water by b for mixed vapour.Also be connected to the rotation blow-off pipe on the stamen pipe exit, cut with scissors on the imperial coil pipe exit and be connected to the rotation air inlet pipe; To entering along the rotation air inlet pipe, walked along guide f by the rotation blow-off pipe by condensed water by e for high-temperature steam.Material,, is stirred and promotes at the imperial coil pipe of hinge (3) and move forward down in screw feeder (6) enters hothouse (4) to adding by g, the material of drying through auger stripper (12) along h to discharge.At a of steam jet pump (9) to adding high temperature and high pressure steam, because high-pressure injection, at c to producing vacuum, the indirect steam of the interior material evaporation of hothouse (4) is extracted out along exhaust tube (8), mixed vapour behind energization by b to, guide to chuck space between chuck (5) and the hothouse (4) through air inlet tube (7), heat; Condensed water is led away along the d direction by blow-off pipe (1); Thereby finish whole dry run.

Vapour, is entered the imperial coil pipe of hinge (3) and adds thermal material to through rotation air inlet pipe (10) by e, and condensed water is walked along guide f through rotation blow-off pipe (11) by stamen pipe (2), and spiral coil can be a single tube, and is also can multitube arranged side by side.

The utility model compared with prior art, the beneficial effect that has is:

1, thermal efficiency height: compare with traditional steam-heated drier (or claiming the single-action drying machine), because the present invention can all utilize indirect steam, therefore can be described as drier; The thermal efficiency may meet or exceed 100% fully; And material water ratio is more high, the thermal efficiency is also more high.

2, rate of drying is fast: because the present invention has heat drying and vacuum drying two big functions/dryings concurrently, and the unit volume inner heating surface is big, and the heat transfer coefficient height is so rate of drying is than faster with drier.

3, lower than cost: as because compact conformation, rationally, of the present inventionly can to reduce more than 30% than cost.

Advantages such as in addition, the present invention also has running steadily, and adjustability is good.

According to the dry requirement of material, the present invention can be made into the serial drier of different size model.

Therefore, the utility model is a kind of full effect energy-saving drying machine to coming dry bulk, powder shape, plaster material with Steam Heating, has great application value.

Claims
