Description
Technical field
The present invention relates to a kind of installation method of sintering machine, in particular, the present invention relates to a kind of installation method of sintering machine dust pelletizing system.
Background technology
Generally, sintering machine is mounted in multi storied factory building, and installs by order from bottom to top.In the whole process of installing sintering machine, the operation of most critical is the installation of dust pelletizing system.
Fig. 1, Fig. 2 respectively illustrate the situation of sintering machine dust pelletizing system component units, this component units comprises and is positioned at sintering machine factory building and the flue-dust retainer 4 being arranged on little lattice funnel 2 on upper strata Cement Concrete beam 6, being arranged on the cleaning shaft 3 on middle level Cement Concrete beam 6 and being arranged on below described cleaning shaft 3 by support of pipelines 5, and the conventional installation methods of this component units comprises the following steps:
(1) surveying setting-out on the Cement Concrete beam 6 of factory building absolute altitude a, determines center line locus and the center line absolute altitude b of cleaning shaft 3;
(2) set up steel platform in factory building head 1 side, the upper surface absolute altitude a of described steel platform is the lower surface absolute altitude of interim slideway (being generally H profile steel);
(3) make a temporary trolley being suitable for interim slideway, and the power that a hoist engine slides as dilatory temporary trolley on described interim slideway is installed in factory building tail side;
(4) temporary trolley is moved to steel platform, with 25t crane, the component units of dust pelletizing system is placed on temporary trolley sequentially, drag temporary trolley to corresponding installation site with hoist engine;
(5) with temporary trolley, little lattice funnel 2 is transported to relevant position, then promoted with driving a vehicle in jack or factory building, and be temporarily fixed at the height that can not affect cleaning shaft 3 and transport with temporary support;
(6) transport to relevant position with the group joint of temporary trolley by composition cleaning shaft 3 and brought up to more than the setting height(from bottom) of support of pipelines 5 with jack, then, support of pipelines 5 under first this group being saved installs, then is fixed on mounted support of pipelines 5 by this group joint;
(7) step (5) and step (6) is repeated, until each group joint of each little lattice funnel 2, support of pipelines 5 and composition cleaning shaft 3 installs;
(8) with wooden handcart the flue-dust retainer 4 be arranged on below cleaning shaft 3 is transported to the certain position outside factory building, the relevant position below described cleaning shaft 3 is dragged it to again with tractor, then moved to erectility with 4 jacks and be pulled to vertically upward and connected with described cleaning shaft 3, welding in place;
(9) after described flue-dust retainer 4 installs, cut and peel off the arc of itself and cleaning shaft 3 joining part, and this block arc is transported after pipe interior is cut into small pieces;
(10) laying and welding of walking on stage cleaning shaft 3 inside is completed.
In the installation method of above-mentioned prior art:
The installation of each group joint of described cleaning shaft 3 needs time of 3 days, and all group joint installation in position needs 1 first quarter moon to time of 2 months.
The installation of described flue-dust retainer 4 each need time of 1 day, whole flue-dust retainer 4 installation in position needs the time of 20-30.
After each flue-dust retainer 4 installs, itself and described cleaning shaft 3 connecting position cut and peel off arc must be cut into small pieces from the inside of described cleaning shaft 3 again after just can transport, substantially become the waste product waste material that can not again utilize.
If install relatively large cleaning shaft 3, often need 25T crane about more than 30 machine-team, artificial work day 400-600, auxiliary material expense about 10,000 yuan, total installed cost (TIC) about 200,000 yuan, and the installation of flue-dust retainer 4 also needs 25T crane more than 20 machine-team, artificial work day 200-300, auxiliary material expense about 5000 yuan, total installed cost (TIC) about 100,000 yuan, two expenses amount to about 300,000 yuan.
The installation of described support of pipelines 5, can only relevant position be transported at each group joint of described cleaning shaft 3 and just can carry out after proper height of slinging with jack, and due to limited space, be difficult to use its alignment error of instrument testing after mounting again, be difficult to ensure installation quality.
The unsettled lifting of described cleaning shaft 3 and the installation of described support of pipelines and flue-dust retainer 4, all operate with multiple jack, and unavoidable effort is time-consuming; The installation of described support of pipelines 5 is then under unsettled cleaning shaft 3, there is inevitable potential safety hazard.
In sum, really there is many deficiencies in the conventional installation methods of described sintering machine dust pelletizing system:
(1) set-up time is long; (2) mounting cost is high; (3) installation quality not easily ensures; (4) hidden danger is installed more.
