Abstract

The invention provides a coil pipe type heating rake drier which aims to solve the problem that a hollow shell wall steam heating cavity of a drier is too big so as to be unsafe and waste steam energy. In the invention, a coil pipe is used for replacing the hollow steam heating cavity on the shell wall of the drier, thereby reducing steam gathered energy and while achieving the same uniform heating effect, improving the security of equipment, and reducing a part of energy consumption.

Description

Coil pipe type heating rake drier

Affiliated technical field:

The present invention relates to a kind of coil pipe type heating rake drier, be used for steam-heated rake type drier field.

Background technology:

Rake type drier is used for chemical industry, feed, food service industry more, carry out the drying processing of pellet, powder, hollow shell wall is established in the drier outside, the hollow heated barrier is established in inside, utilizing steam to charge into hollow heats, material to be dried fully contacts with heater blocks such as shell walls under situation about being stirred, thereby obtains the effect of heat drying.At present, drier hollow tube wall on the market adopts pressure container standard design more, and its concrete grammar is: be provided with a hollow shell wall as steam heating cavity, like this around whole drier almost, though reached the effect of even heating, but because steam pressure is big, the temperature height makes whole cavity be full of huge energy, just in case seepage or blast can bring very big loss, and volume is too big, and loss steam energy in vain often is to energy-conservation unfavorable with safety.

Summary of the invention:

Too big for solving the drier hollow shell wall steam heating cavity, thereby it is dangerous, and the problem of waste steam energy, the present invention proposes a kind of coiled pipe formula and adds hear rate formula drying machine, it realizes that content is such: cancellation hollow steam heating cavity on the drier shell wall, replace serpentine coil, so-called serpentine coil is the semicanal that is attached on the drier shell wall, semicanal is with curve shapes such as " S " type or spiralitys, intensive seeking connections with on shell wall, and fully contact with shell wall, make shell wall evenly obtain managing the heat of interior steam.

The invention has the beneficial effects as follows: drier is reaching the volume that has reduced steam under the prerequisite that evenly adds thermal effect equally, has improved the security of equipment, has also reduced the part energy consumption simultaneously.

Description of drawings:

Accompanying drawing 1 is a front view of the present invention, and accompanying drawing 2 is side views of the present invention,

Accompanying drawing 3 is original dryer configuration front views, and accompanying drawing 4 is original structure side views,

Wherein: (1) serpentine coil, (2) drier shaft, (3) heating steam is imported and exported, (4) material gateway, (5) drier hollow shell wall steam heating cavity, (6) drier inner wall, (7) drier cavity.

Embodiment:

In Fig. 1 and Fig. 2 embodiment of the invention, heating steam is imported and exported (3) from heating steam and is entered serpentine coil (1), serpentine coil (1) is attached on the drier inner wall (6) with the form of semicanal, with curve shapes such as " S " type or spirality, intensive seeking connections with, and contact fully with it, the heat of steam is in the material in the drier cavity (7) in making it evenly to obtain managing, and stirs with drier shaft (2), fully contact, just obtained heat drying with drier inner wall (6).

In the original dryer configuration of Fig. 3 Fig. 4, heating steam is imported and exported (3) from heating steam and is entered former drier hollow shell wall steam heating cavity (5), hollow shell wall steam heating cavity (5) is attached on the drier inner wall (6) with the form of cavity, because the form of cavity is bigger than the form volume of semicanal, so it is dangerous again to have wasted vapor volume.

Claims

1. coil pipe type heating rake drier, comprise: serpentine coil, the drier shaft, heating steam is imported and exported, the material gateway, the drier inner wall, the drier cavity, feature is: serpentine coil is attached on the drier inner wall with the form of semicanal, uses various curve shapes, intensive seeking connections with, and contact fully with it.
