Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the using state schematic diagram of Fig. 1.
Detailed description of the invention
Embodiment: the heat exchanger bobbin carriage good antiscale property flat bottom cover of the present embodiment as depicted in figs. 1 and 2, comprise vertical cylindrical tube 1, the sidewall of cylindrical shell 1 has the charging aperture 1-1 for inputting treating material, flat bottom cover 3 is also welded with at the top of cylindrical shell 1, have tube sheet 2 at the bottom welding of cylindrical shell 1, the below and first of tube sheet 2 is heated tubulation 4, second and is heated tubulation 5, the 3rd and heat tubulation 6, the 4th and heat tubulation 7 and be connected with the hot tubulation 8 of slender acanthopanax.Install for the ease of segmentation manufacture and splicing, the edge of tube sheet 2 extends to the outside of cylindrical shell 1 and forms flange.
In cylindrical shell 1, be welded with vertical rectangle first deflection plate 9 and the second deflection plate 10, its side all connects with the vertical inner wall of cylindrical shell 1, and its top margin all connects with flat bottom cover 3, and its base all connects with tube sheet 2.Cylindrical shell 1 is divided into independently the first chamber, the second chamber and the 3rd chamber by the first deflection plate 9 and the second deflection plate 10, wherein the first chamber charging aperture 1-1 and first heats tubulation 4, second chamber second heats tubulation 5 and the 3rd and heats tubulation 6, and the 3rd chamber the 4th heats tubulation 7 and the hot tubulation 8 of slender acanthopanax.The top being fixed with the first U-board 11, second chamber at the top of the first chamber is fixed with the second U-board 12, and be fixed with the 3rd U-board 13 at the top of the 3rd chamber, wherein one end of the first U-board 11 is welded in the inner side of cylindrical shell charging aperture 1.
The manufacture of above-mentioned heat exchanger bobbin carriage good antiscale property flat bottom cover can be completed by following steps:
First according to design size cutting stock, comprise cylinder lateral wall and launch the rectangle with deflection plate and the circle of flat bottom cover and tube sheet.
Then veneer reeling machine roll-forming cylindrical shell is used, then solder joint, go up veneer reeling machine school circle after welding again.
Subsequently cylindrical shell is placed in turning rolls, during welding, turning rolls drives cylindrical shell slow circumvolve, and welding gun is fixed relative to turning rolls, thus weld seam is moved along the edge of cylindrical shell, flat bottom cover is welded in one end of cylindrical shell and forms flange in edge.
Then in cylindrical shell, weld deflection plate, by turning rolls adjustment cylindrical shell angle during welding, make deflection plate level, adopt the mode of horizontal position welding to weld.
Fold U-board according to the size of cylinder lumen room, and U-board two ends are weldingly fixed in chamber, make the turning point of U-board be close to flat bottom cover.
Subsequently at the other end welding tube sheet of cylindrical shell, at cylindrical shell side welding charging aperture, the flatness of bottom tube sheet and flange is corrected, carries out surface cut if desired.
Carry out the water pressure test after dimensional parameters all meets the demands, guarantee that all weld seams carry out external coating without after leakage.
During use, as shown in Figure 3, treating material enters in the first chamber of cylindrical shell 1 along charging aperture 1-1, is subject to the stop of flat bottom cover 3 and the first deflection plate 9, the section of seamlessly transitting along the first U-board 11 turns to down, enters the first heating tubulation 4 and decline through the hole on tube sheet 2.Because evaporation crystallization equipment adopts high-pressure pump to carry out forced circulation, material is turned back at the end socket place of bottom and is entered the second heating tubulation 5 and rise, arrive the stop being subject to flat bottom cover 3 and the first deflection plate 9 and the second deflection plate 10 after in second chamber at top, the section of seamlessly transitting along the second U-board 12 turns to down, enter the 3rd heating tubulation 6, material is turned back at the end socket place of bottom and is entered the 4th heating tubulation 7 and rise, arrive in the 3rd chamber at top, the section of seamlessly transitting along the 3rd U-board 13 turns to down again, and enter bottom bulkhead from hot tubulation 8 decline of slender acanthopanax and discharge.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
