Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
As can be seen from Fig. 1-5: steam distribution chamber of the present invention, comprise main steam chest 1, condensation hydroecium 3, the steam branch pipe 2 be connected with main steam chest 1 respectively and return pipe 5; Condensation hydroecium 3 is connected with main steam chest 1 with return pipe 5 respectively by steam branch pipe 2; Main steam chest 1 front end is provided with steam inlet 15, back-end closure; The stage casing of steam branch pipe 2 and being connected with the heating tube 6 of the parallel distribution of identical gradient in groups.
Wherein, this main steam chest 1 is inside and outside two layered cylinder wall construction, its cross section is circular, main steam chest 1 is defined as concentric urceolus 7 and inner core 8 by inside and outside barrel, urceolus 7 and inner core 8 rear end are closed by end socket I14, urceolus 7 front end is connected with end socket II17, end socket II17 offers steam inlet 15, and inner core 8 front end is opened wide and is communicated with urceolus 7; The gusset 9 play fixed supporting role also is provided with between urceolus 7 and inner core 8.
Steam branch pipe 2 is uniformly distributed in the radial direction of main steam chest 1, and arranges with the axes normal of main steam chest 1; One end of steam branch pipe 2 is communicated with main steam chest 1 by steam inlet pipe 4, and steam inlet pipe 4 extends in inner core 8, and the other end of steam branch pipe 2 is communicated with one end of condensation hydroecium 3 by admission metal hose 16.Return pipe 5 is made up of interconnective straight tube 10 and backwater metal hose 11, and straight tube 10 stretches in urceolus 7 and is connected with main steam chest 1, and backwater metal hose 11 is connected with the other end of condensation hydroecium 3.
Condensation hydroecium 3 can be made up of several mutual independently condensed water chamber units, and generally preferably 2 ~ 5 condensed water chamber units form, and the shape of condensation hydroecium 3, condensed water chamber unit is circular arc, concentric with main steam chest 1, and along main steam chest 1 circumferencial direction distribution.Steam branch pipe 2 is also divided into 2 ~ 5 groups, often organizes steam branch pipe and is made up of 2 steam branch pipes be parallel to each other 2; Often organize the corresponding condensation hydroecium 3 of steam branch pipe 2.Condensation hydroecium shown in Fig. 1 and Fig. 3 is 3 condensed water chamber units, and steam branch pipe is correspondingly divided into 3 groups; Condensation hydroecium shown in Fig. 2 and Fig. 4 is 5 condensed water chamber units, and steam branch pipe is correspondingly divided into 5 groups.
The specific works mode of steam distribution chamber of the present invention is: first, by the rear end of main steam chest 1 higher than front end and with the gradient of 1.5:100 ~ 5:100 inclination installation; And each heating tube 6 is connected on corresponding steam branch pipe 2 by same slope then; Finally, each group of steam branch pipe 2, return pipe 5 are connected with corresponding condensation hydroecium 3.Whole steam distribution chamber, together with heating tube 6, does gyration along drum dryer body axis; Steam as thermal source enters main steam chest 1 from the air intake of swivel joint 12, via steam inlet pipe 4, steam branch pipe 2, flows into the heating tube 6 be connected with steam branch pipe; After steam in heating tube 6 and outside material-heat-exchanging, the condensed water produced is collected in each steam branch pipe 2 under gravity, when condensation hydroecium 3 rotates to lower than when being attached thereto the position of logical steam inlet pipe 4, the condensed water in steam branch pipe 2 is just taken advantage of a situation and is flowed into condensation hydroecium 3; When condensation hydroecium 3 rotates the position extremely higher than the return pipe 5 be communicated with it, condensed water is recycled to the urceolus 7 of main steam chest 1 by return pipe 5, due to the existence of inner core 8, effectively stops the condensed water flowed down to pour in down a chimney to steam inlet pipe 4.Return pipe 5 stretches out certain length in urceolus 7, and condensed water keeps certain liquid height at urceolus 7, and unnecessary water is discharged to steam distribution outdoor by pumping equipment 13 continuous print.
