Detailed Description
The following describes in detail embodiments of the present invention with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present invention.
The air pipe assembly of the dust removal system in the prior art is assembled by adopting a construction process from a dust remover to each dust suction point so as to ensure the integral stability of a pipeline in the construction process; for the problems of flange hole dislocation, pipeline deviation and the like, the common solution at present is to weld after adjusting hole positions by cutting a pipeline or a flange or to prepare redundant pipes with different pipe diameters in advance, and eliminate the deviation in modes of cutting repair welding and the like according to actual conditions.
In the prior art, a large number of cutting and welding process steps are added, so that the construction period is prolonged while the technical difficulty is improved, the integrity of the pipeline is changed while the site construction cost is increased, and the quality and the sealing performance of the pipeline are reduced; in addition, under the condition that the pipelines are interfered, a mode of changing the local trend of the pipelines by cutting off partial pipelines can cause a series of problems of insufficient pipe length, incorrect angle, pipeline dislocation and the like.
In view of this, the utility model provides a dust removal pipeline.
The dust removal duct of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1, in the embodiment of the present invention, a dust removing pipeline is provided, wherein the dust removing pipeline includes a main dust suction pipeline 10 and an auxiliary dust suction pipeline 20, dust suction ends of the main dust suction pipeline 10 and the auxiliary dust suction pipeline 20 are all provided with a dust suction head 21, a dust outlet end of the main dust suction pipeline 10 is connected with an external dust collecting device, and a dust outlet end of the auxiliary dust suction pipeline 20 is communicated with the main dust suction pipeline 10. The auxiliary dust suction pipe 20 includes at least three telescopic pipes 22 connected in sequence and capable of extending and retracting, and the extending directions of the plurality of telescopic pipes 22 intersect in a three-dimensional space.
The main dust suction pipeline 10 and the auxiliary dust suction pipeline 20 share the same external dust collecting device, wherein the dust collecting device can be a sorting box, a belt conveyor and the like which are common in the prior art; the dust collection operation is carried out on the machine equipment with different placing positions through the dust collection head 21, when all pipelines in the pipelines are in butt joint, the dust collection head 21 of the main dust collection pipeline is connected with the corresponding machine equipment, and then the telescopic sleeve 22 which can be stretched in different directions on the auxiliary dust collection pipeline is adjusted, so that the dust collection head 21 of the auxiliary dust collection pipeline 20 can be adjusted in position in a three-dimensional space to be in butt joint with another machine equipment needing dust collection, and therefore the technical problem of pipeline deviation during pipeline assembly is solved.
Specifically, three telescopic pipes 22 shown in fig. 1 are illustrated as extending in the up-down, left-right, and front-rear directions, respectively; the three telescopic tubes 22 can respectively adjust the positions of the dust collection head 21 of the auxiliary dust collection pipeline 20 in the up-down, left-right and front-back directions through stretching, so that the position of the dust collection head 21 can be changed in any mode in a three-dimensional space, and mechanical equipment needing dust collection can be butted. However, the extending and retracting directions of the three telescopic tubes 22 are not limited to the up-down, left-right, and front-back directions shown in fig. 1, and may be different directions in a three-dimensional space, or may be three or more than three telescopic tubes 22, as long as the effect of extending in the three-dimensional space is achieved by the set of the plurality of telescopic tubes 22. When there is interference in the other structures of the trend of predetermineeing and the actual job site of dust removal pipeline, through the utility model provides a nimble equipment design, can be in the pipeline installation process through the length change pipeline of adjustment telescopic tube 22 and walk to avoiding interfering, compare in prior art through the solution that the local trend of excision part pipeline changes, not only can have good adaptability to various complicated operational aspect, the installation of pipeline is convenient and fast more moreover.
Further, the utility model discloses still provide an optimal pipeline assembly method to this dust removal pipeline, as shown in fig. 1, connect the telescopic tube 22 at vice dust absorption pipeline 20 both ends respectively on the dust absorption head 21 that the position has been fixed and main dust absorption pipeline 10 earlier, install the telescopic tube 22 at vice dust absorption pipeline 20 middle part again, do not weld between telescopic tube 22's outer pipeline 221 and the interior pipeline 222 during the installation and fix, can rely on dust absorption head 21 and main dust absorption pipeline 10 to fix and adjust the pipeline to spacing and the supplementary hoist device of both ends telescopic tube 22 outer pipeline 221, if adopt telescopic tube 22 to dock the mode of installation in proper order, for avoiding in the installation in-process interior pipeline 222 from outer pipeline 221 internal slipping and confirm the turn to scheduling problem of return bend 23 under the spacing prerequisite of only one end, need fix each interior outer tube in advance spot welding, thereby bring inconvenience for follow-up adjustment. So the utility model discloses an assembly of dust removal pipeline adopts from both ends to the centre, the assembly methods of first quiet back moving, agrees with sleeve structure that can be better to still can solve the problem of pipeline skew.
In the embodiment of the present invention, because the extending directions of the different telescopic tubes 22 are not consistent, the adjacent telescopic tubes 22 cannot be directly connected to each other, and therefore, any two adjacent telescopic tubes 22 are connected to each other through the bent tube 23.
In the embodiment of the present invention, as shown in fig. 2, the telescopic tube 22 includes an outer tube 221 and an inner tube 222 that are nested and slidably inserted, and the outer diameter of the inner tube 222 is 2mm smaller than the inner diameter of the outer tube 221, so that the inner tube 222 can freely translate and rotate in the outer tube 221, and the extension length of the telescopic tube can be controlled by adjusting the depth of the inner tube 222 inserted into the outer tube 221. Wherein, after all pipe fittings of dust removal pipeline have all been installed, the telescopic tube 22 need not stretch out and draw back again, can weld the juncture of outer pipeline 221 and interior pipeline 222 in every telescopic tube 22 to guarantee the leakproofness of whole dust removal pipeline, this process does not change the integrality of pipeline, also can not influence the quality of pipeline itself.
It should be noted that the inner pipe 222 can rotate freely inside the outer pipe 221, and the rotation of the inner pipe 222 can drive the flange on the inner pipe 222 to rotate, so as to adjust the position of the flange hole, thereby solving the problem of the dislocation of the flange hole.
Further, in combination with actual requirements and material cost, the length of the inner pipe 222 is preferably 300mm, and the sum of the length of the outer pipe 221 and the half length of the inner pipe 222 is the original design length of a straight pipe, so that the adjustable range of the length of the sleeve pipe is ensured to be +/-150 mm.
The structure of the telescopic tube 22 of the present invention is described in detail above with reference to fig. 2, but the present invention is not limited thereto.
