Abstract

The utility model relates to an efficient and multi-chamber novel steam pipe rotary cylindrical dryer, which comprises a screw feeder, a cylindrical shell, steam heating pipes, pipe supporting plates, a material discharging cabinet and the like. The shell-side heat-exchange space inside the cylindrical shell is of a sectional type structure, wherein single-chamber sections and multi-chamber sections are alternately arranged. Within each multi-chamber section, chamber division separator plates are arranged among the pipe supporting plates. According to the technical scheme of the utility model, the material filling rate is improved and the heat transfer area is increased to improve the heat utilization rate. Meanwhile, the defect that the heat transfer effect of an existing single-chamber dryer is realized by increasing the length of a cylindrical shell is overcome. The manufacturing difficulty and the manufacturing cost are effectively reduced.

Description

Efficient multicell Novel steam steam pipe revolving drum drier

Technical field

The utility model relates to a kind of efficient multicell Novel steam steam pipe revolving drum drier.

Prior art

Follow the modern chemistry industry material output that is dried large, the characteristics that initial wet content is high, force traditional steam pipe drying machine towards maximizing or the large future development, and the interior shell side heat transfer space of the cylindrical shell of steam pipe revolving drum drier commonly used all adopts single cell structure in the at present industry, be material only at the single shell side inner drying of cylindrical shell, the major defect of this structure is:

1, during equipment operation, material only is distributed in drum shaft to bottom, and the inner barrel filling rate is low, generally only reaches 15 ~ 25%, and heat exchange area only can utilize 30%.

2, heat exchange efficiency is low, cylindrical shell and heating tube specification, arranges and to need in the identical situation by increasing cylindrical shell length to reach heat transfer effect.

3, bulky, installation, dismounting, Problem be difficulty, and manufacture difficulty is large, and equipment cost is high.

Summary of the invention

The purpose of this utility model is to provide that a kind of heat transfer efficiency is high, compact conformation rationally, low cost of manufacture, installation and maintenance efficient multicell Novel steam revolving drum drier easily.

The utility model can be achieved through the following technical solutions:

A kind of efficient multicell Novel steam steam pipe revolving drum drier, comprise screw feeder, cylindrical shell, steam-heating pipe, tube support plate, feed box etc., the shell side heat transfer space is single chamber, the setting of multicell alternatively, sectionally formula in the cylindrical shell, and the locellus dividing plate is set between tube support plate in the multicell vertically;

Described locellus dividing plate is three to six, and is divided into the independent shell side heat transfer space that respective numbers is equal to.

Described locellus dividing plate is three, and three dividing plates are mutually 120 ° of angles, and the shell side heat transfer space has been divided into three independently shell side heat transfer spaces;

The utility model has following advantage and good effect compared to existing technology:

1, Effective Raise the inner barrel filling rate, traditional single chamber drying machine filling rate only is 15 ~ 25%, usually can only reach about 20%; And the filling rate of novel multicell drying machine is promoted to 30 ~ 60%, generally can reach about 50%;

2, improved heat utilization efficiency, in the constant situation of heat transfer effect, the cylindrical shell effective length can have been shortened 1/3 ~ 1/2, thereby effectively reduce manufacture difficulty and cost;

3, compact conformation can be applicable to large-scale steam pipe revolving drum drier (φ 3800 ~ φ 4800), and multicell section dividing plate does not affect the inner barrel maintenance.

The specific embodiment

The utility model also is described in further detail in connection with the specific embodiment:

With reference to accompanying drawing, a kind of efficient multicell Novel steam steam pipe revolving drum drier, comprise screw feeder 1, steam-heating pipe 2, cylindrical shell 3, tube support plate 4, feed box 6 etc., cylindrical shell 3 interior shell side heat transfer spaces are single chamber, multicell alternatively, sectionally formula arranges, the cylindrical shell segmental structure is followed successively by " single chamber L1---multicell L2---single chamber L3---multicell L4---single chamber L5 " structure, 4 of tube support plates locellus dividing plate 5 is set vertically in the multicell, it is three that accompanying drawing is depicted as locellus dividing plate 5, three dividing plates are mutually 120 ° of angles, and the shell side heat transfer space has been divided into three independently shell side heat transfer spaces; Locellus dividing plate 5 can also four be mutually 90 ° of angles, five and be mutually 72 ° of angles, six locellus dividing plates that are mutually 60 ° of angles in addition.

The utility model course of work is as follows:

After wet stock is admitted to drying machine cylindrical shell 3 charging apertures by screw feeder 1, at first through first section single chamber L1 preliminarily dried, under the effect with the drying machine rotation, it is interval further dry to be redistributed to the L2 multicell, this moment, material was divided into three parts equably, every part with in the drying machine rotation process with after heat exchanger tube fully contacts, obtain further drying.For improving drying effect, guarantee that dried material humidity is even, the three part dischargings of L2 section are evenly mixed in the L3 section, reassign to L4 multicell section after the drying and carry out the locellus drying, converge at last L5 single chamber section, deliver to feed box 4 positions after mixing and enter hopper, finish the overall process of dry materials.

Novel steam steam pipe revolving drum drier passes through design accounting, each segment length size regulation of cylindrical shell is followed successively by: L1 ≈ 2m, L2=(3 ~ 3.5) * L1, L3=(1 ~ 1.5) * L1, L4=(3 ~ 3.5) * L1, L5=(1 ~ 1.5) * L1, material discharge by feed box replace successively drying in the multistage heat transfer space after.
