Abstract

The invention relates to a novel high-efficient multi-chamber steam pipe rotating cylindrical dryer which comprises a screw feeder, a barrel, a steam heating pipe, pipe supporting plates and a discharging box, wherein the shell pass heat exchange space in the barrel is arranged in the form of a single chamber and multi-chamber alternated section; chamber-separating plates are arranged between the pipe supporting plates in the multi-chamber along the axial direction. According to the invention, the material filling rate is increased; the thermal utilization rate is increased by increasing the heat-transfer area, the defect of the present single-chamber dryer that the heat transfer effect is achieved by increasing the length of the barrel is overcome, and the manufacturing difficulty and cost are effectively reduced.

Description

Efficient multicell Novel steam steam pipe revolving drum drier

Technical field

The present invention 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 feature that initial wet content is high, force traditional steam pipe drying machine towards maximizing or large future development, and the interior shell side heat transfer space of the cylindrical shell of conventional steam pipe revolving drum drier all adopts single cell structure in industry at present, 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 is only distributed in drum shaft to bottom, and 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 in identical situation, needs by increasing cylindrical shell length to reach heat transfer effect.

3, bulky, installation, dismounting, Problem are more difficult, and manufacture difficulty is large, and equipment cost is high.

Summary of the invention

The object of the present invention 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 present invention 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., in cylindrical shell, shell side heat transfer space is single chamber, the setting of multicell alternatively, sectionally formula, and locellus dividing plate is set in multicell vertically between tube support plate;

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 shell side heat transfer space has been divided into three independently shell side heat transfer spaces;

The present invention compared to existing technology tool has the following advantages and good effect:

1, effectively improved inner barrel filling rate, traditional single chamber drying machine filling rate is only 15 ~ 25%, conventionally can only reach 20% left and right; And the filling rate of novel multicell drying machine is promoted to 30 ~ 60%, generally can reach 50% left and right;

2, improved heat utilization efficiency, in the situation that heat transfer effect is constant, cylindrical shell effective length can have been shortened to 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 inner barrel maintenance.

The specific embodiment

The present invention is also 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., the interior shell side heat transfer space of cylindrical shell 3 is single chamber, multicell alternatively, sectionally formula arranges, cylindrical shell segmental structure is followed successively by " single chamber L1---multicell L2---single chamber L3---multicell L4---single chamber L5 " structure, in multicell, 4 of tube support plates, locellus dividing plate 5 is set vertically, it is three that accompanying drawing is depicted as locellus dividing plate 5, three dividing plates are mutually 120 ° of angles, shell side heat transfer space has been divided into three independently shell side heat transfer spaces, in addition locellus dividing plate 5 can also four mutual angle in 90 °, five be mutually 72 ° of angles, six locellus dividing plates that are mutually 60 ° of angles.

The course of work of the present invention is as follows:

Wet stock is admitted to after drying machine cylindrical shell 3 charging apertures by screw feeder 1, first through first section of single chamber L1 preliminarily dried, under the effect of rotating with drying machine, be redistributed to L2 multicell interval further dry, now material is divided into three parts equably, every part, with after fully contacting with heat exchanger tube in drying machine rotation process, is further dried.For improving drying effect, guarantee that dried material humidity is even, the three part dischargings of L2 section are evenly mixed in L3 section, after dry, reassigning to L4 multicell section, to carry out locellus dry, finally converge to L5 single chamber section, after mixing, deliver to feed box 4 positions and enter hopper, complete 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 replaces after dry successively in multistage heat transfer space discharges by feed box.
