Description
Technical field
The present invention relates to a kind of drying equipment, particularly a kind of revolving drum type tube bundle drying machine.Drying machine of the present invention can heat, overturn, stir restraining outer material by the heat exchange of tube bank and the rotation of rotating cylinder, thereby makes material reach the purpose of even drying.This invention is specially adapted to the drying processing of bulk material, and in Alcohol Plant, meat connection industry, fertilizer industry, corn deep processing industry, feedstuff industry all can be used widely.
Background technology
Pipe bundle drier is a kind of according to heat conduction and thermal radiation principle, by heat biography the be dried material to tube wall outside of heat exchanger tube tube wall with water vapour, to reach the plant equipment of dried material purpose.The core component of this plant equipment is the heat exchanger tube tube bank.
The structure of prior art pipe bundle drier as shown in Figure 1 and Figure 2, the following (see figure 1) in path of its water vapour turnover heat exchanger tube: steam enters the inner chamber of admission end end socket 2 and admission end tube sheet 3 compositions from air intake 1, enter in the heat exchanger tube 4 that is connected with tube sheet from this inner chamber again, the water vapour that enters heat exchanger tube is after finishing its heat transfer process, enter in the inner chamber that steam output end end socket 6 and tube sheet 5 form and become condensate water, discharge from steam output end venthole 7 then.
The path of this steam turnover heat exchanger tube has determined the structure of heat exchanger tube tube bank: the heat exchanger tube tube bank must be provided with two than the end socket 2,6 of major diameter (general about 1.2 meters to 3 meters) and the cavity of tube sheet 3, the 5 composition one of thickness big (about general 40-100mm).These two cavitys must be integral its connection by the heat exchanger tube 4 of some and length again.In this structure, end socket and tube sheet material require high (must use the 16Mn tank plate) so and consumption also cost is higher greatly.In addition, be connected (see figure 2) between heat exchanger tube and the tube sheet, require sealing, the inaccurate leakage, need to adopt expand, the processing technology (see Fig. 2, require expanded joint at 9 places, require seal welding at 10 places) of weldering and usefulness, the manufacturing process complexity, difficulty is big.Carelessness is arranged slightly, will cause leakage, be directed at stop production to overhaul.
The rotary course of this traditional pipe bundle drier heat exchanger tube is: motor passes through transmission mechanism, driving steam output end end socket tube sheet rotates together, by the tube bank heat exchanger tube (and the outer flight angle steel 8 of tube bank) that is communicated with tube sheet rotary power is passed to admission end end socket tube sheet again, drives whole heat exchanger tube tube bank rotation.This power delivery mode needs bigger transmitted power.In addition, because heat exchanger tube itself also is parts in the power transmission chain, so when transmitting rotary power, connecting portion 9,10 places of heat exchanger tube and tube sheet can be subjected to torsional forces to a certain degree, this torsional forces, being unfavorable for being connected and sealing between tube sheet and the heat exchanger tube, is the one of the main reasons that leak heat exchanger tube and tube sheet junction.
Summary of the invention
A kind of revolving drum type tube bundle drying equipment that purpose of the present invention provides at existing weak point in the above-mentioned prior art just.
Revolving drum type tube bundle drying machine of the present invention comprises that an end is provided with charging aperture, the other end and is provided with the rotating cylinder of discharging opening and is arranged on some heat exchanger tubes in the rotating cylinder cavity in axial arranged mode, and described heat exchanger tube is by be installed in the rotating cylinder inner chamber with two of rotating cylinder inwall Joint horizontal support tube sheets at least; Described heat exchanger tube is made up of the admission heat exchanger tube and the steam discharge heat exchanger tube that are provided with at interval, and per two adjacent admission heat exchanger tubes are communicated with by tube connector with an end of steam discharge heat exchanger tube, constitute a loop, the other end is connected with admission collecting ring, steam discharge collecting ring respectively; Described admission collecting ring and steam discharge collecting ring are connected with admission chamber and steam discharge chamber in the plenum chamber respectively.
Be provided with some flights around the rotating cylinder inwall, be provided with being used to of combining with power source around the rotating cylinder outer wall and drive gear ring that rotating cylinder rotates and the ring-like guide rail that combines with guide roller.
Operation principle of the present invention is as follows:
Revolving drum type tube bundle drying machine of the present invention is the indirect contact drier, utilize heat conduction and thermal radiation principle, to pass the material that is dried outside tube wall as the heat of the saturated vapor of the thermal source tube wall by heat exchanger tube, material is the rotation by rotating cylinder then, at rotating cylinder and be welded under the drive of the flight on the rotating cylinder inwall, be brought to the top of heat exchanger tube in the rotating cylinder, fall the gap between heat exchanger tube again; Under the flight that is obliquely installed promotes, move to discharge end simultaneously, discharge through discharging opening by feed end.Be dried material stir up and down and move forward in the process be heated, drying, thereby finish dry run.
Steam of the present invention is as follows into and out of the path of heat exchanger tube: water vapour enters the admission chamber of plenum chamber from air intake, enter the admission heat exchanger tube through the admission collecting ring, enter the steam discharge heat exchanger tube through tube connector (return bend), enter the steam discharge chamber of plenum chamber again, discharge from gland steam exhauster through the steam discharge collecting ring.This steam of the present invention can save tube sheet 3,5 and end socket 2,6 compared to existing technology into and out of the path, what replace it is that plenum chamber, collecting ring, tube connector (return bend) and support tube sheet 18 of the present invention (only plays effect fixing, that support owing to support tube sheet in structure, do not need also will bear the high steam active force, so the used material of the support tube sheet among the present invention can be that thickness is at 12-25mm left and right sides general steel plate) as tube sheet of the prior art.
Beneficial effect of the present invention is as follows:
1. avoid end socket, tube plate structure and complicated processing technology thereof, reduced manufacturing cost, difficulty of processing.
2. the tube bank heat exchanger tube of being made up of heat exchanger tube is stressed does not when rotated evenly transmit moment of torsion, has reduced to be turned round the possibility of damage greatly.
3. tube bank heat exchanger tube and two ends tube sheet do not need seal weld (expanding) to connect, and have thoroughly stopped the problem of leaking between heat exchanger tube and the tube sheet.
4. tube bank drives by cylindrical shell is whole with material, has reduced the friction of tube bank and flight and material, has reduced transmission power.
