Background technology
Big-and-middle-sized sack cleaner belongs to the steel welding structure of peeling off, and is generally subnormal ambient during work, and the plate face of deduster need bear certain pressure, and that force value is low is 3000~5000Pa, the high 10000~15000Pa that reaches; And deduster is bigger to physical dimension in length and breadth, even by technological requirement, divide whole equipment branch into several cells after, the book size of an one cell is still very big, often grow and the wide 4~6m that reaches, up to 6~8m, promptly the book size of every side plate reaches (4~6) * (6~8) m
2, like this big breadth will tolerate above-mentioned suction function and the plate facial disfigurement is no more than 5~10mm, will just weld a series of reinforcements 40 with the stiffener face every a determining deviation along the vertical and horizontal of plate face usually, as shown in Figure 1.Above-mentioned way steel consumption height, the welding job amount is big, and in order to settle reinforcement 40, needs to strengthen the spacing of inner panel face and filter bag, thereby strengthened equipment size, has improved manufacturing cost.
Summary of the invention
The purpose of this utility model provides a kind of supporting construction that is used for sack cleaner, its simple structure, and stiffening effect is good and the steel consumption amount is little.
For achieving the above object, the utility model has adopted following technical scheme: a kind of supporting construction that is used for sack cleaner, all be set with support column on the inner plate surface of each cycle side plate of formation cleanner bag chamber, described support column extends along the axial direction of bag chamber, the inside of described bag chamber also is set with bracing frame, the residing plane of bracing frame is perpendicular to the axial direction of bag chamber, and bracing frame all is fixed on the support column of respective side panels from the end of the wherein inner plate surface extension of each cycle side plate of mind-set bag chamber.
As shown from the above technical solution, be provided with support column and bracing frame in the utility model, the size that support column calculates the distortion of bag chamber cycle side plate significantly reduces, and panel rigidity significantly improves, and can bear bigger pressure by thin steel plate, steel consumption province and welding job amount are little; The setting of bracing frame has then increased considerably the ability of support column bearing load, thereby makes support column can adopt less shaped steel, has further saved the steel consumption.In sum, the utility model simple structure, stiffening effect is good and the steel consumption amount is little.
The specific embodiment
Shown in Fig. 2,3, a kind of supporting construction that is used for sack cleaner, all be set with support column 20 on the inner plate surface of each cycle side plate 11 of formation cleanner bag chamber 10, described support column 20 extends along the axial direction of bag chamber 10, the inside of described bag chamber 10 also is set with bracing frame 30, bracing frame 30 residing planes are perpendicular to the axial direction of bag chamber 10, and bracing frame 30 all is fixed on the support column 20 of respective side panels from the end of the wherein inner plate surface extension of each cycle side plate 11 of mind-set bag chamber 10.
Further, the direction of the centre symmetry line of the cycle side plate 11 on the bearing of trend of described support column 20 and its are fixed on coincides, this set makes that the side plate of support column 20 both sides is symmetrical mutually, thereby the distortion of cycle side plate 11 is comparatively even, helps prolonging its working life.
As shown in Figure 2, described support column 20 is I-steel or rectangular steel pipe.Described bracing frame 30 is made by steel pipe.
Further, the cross section of described bag chamber 10 is a rectangle, and support column 20 is set to 4, and described bracing frame 30 is a crosswise.
Described bracing frame 30 is provided with 1~2 uniformly along the axial direction of bag chamber 10.When a bracing frame 30 only was set, bracing frame 30 can be arranged on half eminence of support column 20, also promptly was arranged on the middle part of support column 20.
Described each cycle side plate 11 that constitutes bag chamber 10 is contour plate, and described contour plate also is the plate face concave-convex surface of sheet material, this shape effectively resistant function atmospheric pressure onboard to its deformation effect that causes.
Do to explain in detail below in conjunction with Fig. 2,3 pairs of the utility model:
The cycle side plate 11 towards the deduster arranged outside of bag chamber 10 is a panel, and the cycle side plate 11 that is provided with towards the deduster inboard is partition plate or air channel dividing plate, and the cycle side plate 11 of described bag chamber 10 all is set to contour plate; The utility model all is welded with support column 20 on each interior plate face of the rectangular bag chamber 10 of cross section, support column 20 extends axially along bag chamber 10, and the direction of the centre symmetry line of the bearing of trend of support column 20 and its cycle side plate 11 on being fixed on coincides; The utility model edge is perpendicular to also being provided with criss-cross bracing frame 30 on the axial direction of bag chamber 10 simultaneously, bracing frame 30 is welded by steel pipe, and bracing frame 30 all is weldingly fixed on the support column 20 of respective side panels from the end that the inner plate surface of each cycle side plate 11 of mind-set bag chamber 10 wherein extends.
The beneficial effects of the utility model are: first, the width dimensions that support column 20 calculates the panel deformation of bag chamber 10 reduces by half, 16 times of the corresponding comparable original raisings of contour plate rigidity, no longer need to add the weldering rib on the plate face, and can bear bigger withstand voltage by thin profiled sheet, the steel consumption is economized, and the welding job amount is little; The second, crosswise bracing frame 30 bolsters are welded on the middle part of support column 20, also make the ability of support column 20 bearing loads strengthen 16 times, thereby support column 20 can adopt less shaped steel, has further saved the steel consumption; The 3rd, crosswise bracing frame 30 generally forms with steel pipe manufacturing, and each of steel pipe is identical to the moment of inertia, and axial bearing capacity is big, and defensive ability/resistance ability is powerful with the material specification is little; The 4th, this crosswise bracing frame 30 is divided into four groups with the filter bag of a chamber, be equivalent to be provided with a cross passage in the inside of bag chamber 10, the part ash-laden gas of being convenient to enter from the bottom bag chamber 10 can make progress fast through this passage, the dust load of the filter bag upper-lower position around the passage is distributed obtain homogenizing to a certain degree, help improving the processing performance of equipment.
