Along with the extensive use of the split type steam rotary dryer of endless tube, original cheese steam chest and heating tube welding are non-dismountable, maintenance difficult, reasons such as condensed water can't be emptied completely spill cruelly gradually that volume is big, weight is big, complex structure, condensed water is hydrophobic not smooth, makes shortcomings such as difficulty.
Summary of the invention
Purpose of the present invention is exactly in order to solve complex structure, maintenance inconvenience, the big cost height of volume, the hydrophobic not smooth problem that traditional steam chest exists, the invention provides a kind of steam distribution chamber that is applicable to the split type steam rotary dryer of novel endless tube, steam distribution chamber of the present invention be have simple in structure, easy to maintenance, volume is little, the steam distribution chamber of the band condensation hydroecium of low cost of manufacture, hydrophobic advantage such as reliable.
For achieving the above object, steam distribution chamber of the present invention adopts following technical scheme: it comprises main steam chest, the steam branch pipe and the return pipe that link to each other with main steam chest respectively; Main steam chest front end is provided with steam inlet, back-end closure; Steam branch pipe is connected with heating tube; It is characterized in that: also comprise the condensation hydroecium that is arranged on main steam chest outside, the condensation hydroecium is connected with main steam chest with return pipe by steam branch pipe respectively.
The present invention is further improved, and described condensation hydroecium is made up of 2 ~ 5 condensed water chamber units, and steam branch pipe is divided into 2 ~ 5 groups accordingly; Every group of steam branch pipe is made up of 2 steam branch pipes that are parallel to each other, and each condensed water chamber unit is connected with return pipe and one group of steam branch pipe.
The present invention is further improved, and described condensation hydroecium is circular arc, and distributes along the circumferencial direction of the main steam chest concentric with it.
The present invention is further improved, and described main steam chest cross section is circular, and the steam branch pipe distribution arrangement is vertical mutually with main steam chest axis direction.
The present invention is further improved, and described main steam chest is made of concentric urceolus and inner core, and outer tube rear end and interior tube rear end are by end socket I sealing, and outer cylinder front end is connected with end socket II, and the inner core front end is uncovered; Steam inlet is positioned on the end socket II.
The present invention is further improved, and described main steam chest rear end is higher than its front end, and its declining slope is 1.5:100 ~ 5:100.
The present invention is further improved, and described return pipe is made up of interconnective straight tube and metal hose; Wherein, the straight tube end extends in the urceolus, and metal hose is connected with an end of condensation hydroecium.
The present invention is further improved, and an end of described steam branch pipe is communicated with by the other end of metal hose with the condensation hydroecium, is connected with steam inlet pipe between the other end and the main steam chest, and steam inlet pipe one end extends in the inner core.
The present invention is further improved, is provided with gusset between described urceolus and the inner core.
The present invention is further improved, and described steam branch pipe is connected with in groups the heating tube with the identical parallel distribution of gradient.
The present invention is the steam distribution chamber that has the condensation hydroecium, and the main steam chest of this steam distribution chamber is connected with swivel joint, thereby makes steam distribution chamber integral body do gyration along the drum dryer body axis.Steam as thermal source in turning course enters main steam chest from air intake, via steam inlet pipe, steam branch pipe, flows into the heating tube that is connected with steam branch pipe; The condensed water that produces after steam in the heating tube and the outside material heat exchange is collected to each steam branch pipe under the gravity effect, when the rotation of condensation hydroecium was lower than the position of steam inlet pipe to the bottom, the condensed water in the steam branch pipe flowed into the condensed water chamber; When condensation hydroecium rotation when being higher than the position of return pipe, condensed water is recycled to main steam chest by return pipe, inner core has stoped the condensed water that flows down to pour in down a chimney to steam inlet pipe.
Steam distribution chamber of the present invention is equipped with 2 ~ 5 groups of steam branch pipes at main steam chest hoop, and the quantity of steam branch pipe is relevant with the group number of ring-like heating tube, can adjust the quantity of steam branch pipe according to the group number of heating tube.Every group of steam branch pipe has two, and two arms can also can need require according to the reinforcement for openings of bitubular master steam chest urceolus to decide on two different anchor rings on same anchor ring.
Steam distribution chamber of the present invention, main steam chest is double-barrel structure, its rear end is higher than front end, declining slope with 1.5:100 ~ 5:100 is installed, doing in the gyration along the drum dryer body axis, condensed water is recycled to the urceolus of main steam chest by return pipe, and the existence of inner core can stop the condensed water that flows down to pour in down a chimney to steam inlet pipe effectively.
In the steam distribution chamber of the present invention, the urceolus of main steam chest is connected by gusset with inner core, and gusset plays a part fixing and supports inner core.The quantity of gusset can be adjusted according to weight and the size of inner core; The rear end of inner core contacts with the rear end end socket of urceolus, and front end is communicated with urceolus, so that the partial condensation water that steam branch pipe is directly refluxed flows to urceolus, discharges through pumping equipment then.
Steam distribution chamber of the present invention has the following advantages and beneficial effect: 1. steam distribution chamber of the present invention is simple in structure, and volume is little, in the time of self loss of weight, can also reduce the length of steam rotary dryer, thereby reduce manufacturing cost; 2. adopt releasable connection between steam distribution chamber of the present invention and the heating tube, easy to maintenance; Steam distribution chamber of the present invention arranges the condensation hydroecium, and the condensed water in the heating tube can be discharged swimmingly, strengthens the heat exchange effect.
