A kind of heat exchange tank inside dish-type coiled pipe bracing or strutting arrangement
Technical field:
The utility model relates to a kind of heat exchange storage tank, particularly a kind of heat exchange tank inside dish-type coiled pipe bracing or strutting arrangement.
Background technology:
In aluminum oxide production process, often need carry out heat exchange reaction in some tank inside, common practices is to arrange the dish-type coiled pipe in tank inside to feed then that liquid medium carries out heat exchange in steam and the groove.The dish-type coiled pipe of existing heat exchange tank inside all is directly with angle steel one end and the welding of dish-type coiled pipe, the other end with directly be welded on inner tank wall (as shown in Figure 6), though this kind connected mode plays the effect to dish-type coiled pipe fixed support, but there is following defective: one. this structure adopts tank skin to bear dish-type coiled pipe weight, seriously undermined tank intensity, two. consider that the support angle steel is unsuitable long, otherwise can reduce rigidity, so the dish-type coiled pipe should be tried one's best near inner tank wall, and one deck endless tube at the most can only be arranged above and below, cause heat exchange area very few, reduced whole storage tank heat exchanger effectiveness, and since dish-type coiled pipe position be defined extremely, can't balance owing to the stress that expands with heat and contract with cold and bring.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of and can not influence tank intensity, dish-type coiled pipe installation site freedom, can arbitrarily set up dish-type coiled pipe quantity, eliminate the heat exchange tank inside dish-type coiled pipe bracing or strutting arrangement of dish-type coiled pipe stress, can overcome the deficiencies in the prior art.
The technical scheme that the utility model is taked is: it comprises heat exchange storage tank and dish-type coiled pipe, vertically is connected with column in the heat exchange tank bottom, and the dish-type coiled pipe is connected on the column.
Be connected with fixedly angle steel on column, the dish-type coiled pipe is connected fixedly on the angle steel.
Be connected with bracing piece between the column.
Fixedly offering the U-bolt connecting hole on the angle steel, the dish-type coiled pipe is connected fixedly on the angle steel by U-bolt.
One of them hole that is positioned at the U-bolt connecting hole on the fixing angle steel is a slotted hole.
Prior art is compared, and the utility model is by connecting vertical column in the heat exchange tank bottom, and the dish-type coiled pipe is connected on the column, and being connected dish-type coiled pipe on the column can be for individual layer, also can be multilayer; Being provided with like this first can make the dish-type coiled pipe just can not have influence on the intensity of heat exchange reservoir walls; Second because the diameter that stud can arbitrarily be adjusted the dish-type coiled pipe also can arbitrarily be adjusted, and is convenient to heat exchange like this, improves heat exchanger effectiveness and heat exchange area; If the 3rd when needing bigger heat exchange area simultaneously, and the dish-type coiled pipe up and down after the close arrangement when still enough, can be arranged inside and outside which floor endless tube at column, further increases heat exchange area.Be connected with fixedly angle steel on column, the dish-type coiled pipe is connected fixedly on the angle steel, can guarantee like this column intensity, be convenient to connect the dish-type coiled pipe.Between column, connect bracing piece, can improve the stability of column like this.Offer the U-bolt connecting hole on column, the dish-type coiled pipe is connected on the column by U-bolt, can conveniently connect like this with fixing.One of them hole of U-bolt connecting hole is a slotted hole, and when stress deformation appearred in the dish-type coiled pipe, U-bolt can be with the motion of slotted hole direction, the stress that balance is expanded with heat and contract with cold and brought like this.

The specific embodiment
Embodiment of the present utility model: as Fig. 1, Fig. 2 and shown in Figure 3, when making heat exchange storage tank 1, the column of making of channel-section steel 3 is vertically welded at the jar end at heat exchange storage tank 1, dish-type coiled pipe 2 can directly be connected on the column 3, the quantity of column 3 is according to arranging that the quantity of dish-type coiled pipe 2 decides, and decide according to the diameter of dish-type coiled pipe 2 position of column 3; Be the convenient rigidity that connects dish-type coiled pipe 2 and guarantee column, adopt the position that on column 3, will connect dish-type coiled pipe 2 to weld fixedly angle steel 7 more, fixedly offering U-bolt connecting hole 5 on the angle steel 7, one of them hole with U-bolt connecting hole 5 when perforate is slotted hole (as Fig. 4), has offered U-bolt connecting hole 5 back and by U-bolt 6 dish-type coiled pipe 2 has been connected fixedly on the angle steel 7.Because dish-type coiled pipe 2 vibrations when work are bigger,, between column 3, be connected with bracing piece 4 simultaneously for guaranteeing the stability of column.
When if heat exchange storage tank 1 needs big heat exchange area, can on column, connect many fixedly angle steel 7, take the mode of multilayer connection dish-type coiled pipe 2 up and down, when if the dish-type coiled pipe still can not meet the demands after the close arrangement about in the of 2, can connect inside and outside many group columns, arrange inside and outside which floor endless tube (as Fig. 5), further increase heat exchange area.
