Abstract
The utility model belongs to a cooler tube box in mainly used petrochemical field, this kind of cooler tube box comprises parts such as business turn over oral siphon, tube sheet, tubesheet flange, tube box flange, cap, heat exchange tubes, and its characteristics are that rounded rectangle is made by the sheet metal turn respectively to tube sheet and cap, form the whole case of managing through flange, gasket, fastener block mount. This kind of cooler tube box's characteristics lie in: the coefficient of stress concentration of two reducible corners of rounded rectangle box structure reduces the material cost of tube sheet and cap and manages case manufacturing cost, economical and practical.
Description
Technical field
The utility model belongs to a kind of air cooling equipment for oil, chemical field, relates to a kind of two round rectangle air cooler bobbin carriage in particular.
Background technology
Air cooling heat exchanger (abbreviation air cooler) is a kind of energy-efficient cold exchange device, extensively practical in oil refining and chemical process, particularly in the area that water resource lacks, is characterized in water saving, economize on electricity, floor space is little, heat exchange efficiency is high.The existing air cooler bobbin carriage generally used can be divided into two kinds of structures, is threaded plug type bobbin carriage and the board-like bobbin carriage of removable cover respectively.
The material that traditional air cooler bobbin carriage is used is thick and heavy, and weld seam is many, welding job amount large, and the welded stress caused is large, yielding, and manufacturing cost is high.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of two round rectangle air cooler bobbin carriage, while meeting bearing strength, can reduce materials'use cost, reduce welding bead, be convenient to disassembly, cleaning.
For achieving the above object, the two round rectangle air cooler bobbin carriage of the one that the utility model provides is made up of parts such as inlet/outlet pipe, tube sheet, tube sheet flange, channel flange, cap, heat exchanger tubes, be characterized in that tube sheet and cap are bent into round rectangle by sheet metal respectively, form overall bobbin carriage by flange, pad, fastener combination assembling.
The utility model has the advantage of: tube sheet and cap sheet metal used are bent into round rectangle, and two round rectangle body structures can reduce the factor of stress concentration of corner, reduce material cost and the bobbin carriage manufacturing cost of tube sheet and cap, economical and practical.
Detachable cap easy access, the welding point of exchanger tubes and tubesheets is conducive to various detection.
Bobbin carriage is applicable to the use of various types of materials, particularly selects carbon steel material, improves the economic and practical of product.
Accompanying drawing explanation
Fig. 1 is general assembly structural representation of the present utility model.
Comprising: inlet/outlet pipe 1, tube sheet 2, tube sheet flange 3, channel flange 4, cap 5, heat exchanger tube 6, gasket seal 7, securing member 8.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described; the principle that the present embodiment is just described described in the present embodiment and description; the utility model is not limited to embodiment; be combined the expansion in field; the utility model will have and improve or change, these changes and to change will be all in claimed scope.
A kind of two round rectangle air cooler bobbin carriage, tube sheet 2 bend round rectangle by thin-walled steel plate and with tube sheet flange 3 assembly welding, heat exchanger tube 6 and tube sheet 2 adopt exterior angle automatic TIG Welding Machine to connect, welding quality stable.Cap 5 bend round rectangle by thin-walled steel plate and with channel flange 4 assembly welding, inlet/outlet pipe 1 is assembly welding on cap 2.The casing that the casing be made up of tube sheet 2, tube sheet flange 3 and cap 5 and channel flange 4 form carries out fit sealing by gasket seal 7 and securing member 8, form two round rectangle air cooler bobbin carriage, material and low cost of manufacture, manufacture simple, be convenient to internal washing, maintenance, economical and practical.
