Abstract
The invention discloses a detaching method for overhaul of a drier of a fluidized bed. The method mainly comprises bellows, a conduction oil heat exchanger and a suction hood. The method comprises the following steps that: each part and pipelines are marked in detaching; each flange and the pipelines are detached; a jack is placed on a platform on the upper part of the exchanger to support a projection of the bellows; a hanging hook is welded on the platform; the hanging hook and the bellows are connected by a guide chain; a connecting bolt between the bellows and the exchanger is loosened; the steel structure members on the lower part of the bellows are detached; a rolling bar is spread on the ground; the guide chain is pulled to reduce the bellows onto the rolling bar; the guide chain on the bellows is detached; the bellows is moved out by the rolling bar; and the exchanger is removed in the same way; after each part is overhauled, the exchanger and the bellows are arranged by the method in sequence, the flanges, the pipelines and the steel structure members are recovered, and the jack, the hanging hook and the guide chain are detached. The method completes the overhaul of the drier of the fluidized bed by simple equipment and adopting a method of split detachment; and the method greatly shortens the construction period of detachment and improves working efficiency.
Description
Technical field
The present invention relates to a kind of assembly and disassembly methods that is used for the maintaining fluidized bed drying machine of sewage disposal.
Background technology
Fluid bed dryer is widely used in sewage disposal, and its volume is big, weighs more than 20 ton, mainly is made up of bellows, conduction oil heat exchanger and suction hood three parts; Bellows are positioned at the bottom of drying machine, are used for sending inertia fluidizing gas and the needed blast that regulates and distributes drying machine device zones of different.The conduction oil heat exchanger is equipped with on bellows top, forms the heat exchange group, and these heat exchangers carry out mummification and the final dewatered sludge particle that forms with the wet mud of the heat transferred of conduction oil; Suction hood is used for transpiring moisture and fine grained that wet mud fluidisation heating back produces are detached drying machine; Separate through cyclone separator then; The particulate of separating gets into the grey storehouse of separator bottom; Get into blender through grain position automatic control system, process was sent back in the drying machine with mixing again of wet mud, and moisture evaporated is recycled to through two typhoon machines and carries out ciculation fluidized drying in the drying machine through condensation, washing back.
Fluid bed dryer need regularly overhaul, and needs equipment is disintegrated, dismantles whole fluid bed dryer on the spot row installation again after each several part is overhauled when overhauling usually; Its whole process duration is longer, and work efficiency is lower, has had a strong impact on the normal operation of fluid bed dryer and the disposal ability of sewage.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly need not whole decompose the assembly and disassembly methods that fluid bed dryer overhauls, and to shorten the duration of maintaining fluidized bed drying machine dismounting, improves work efficiency.
For solving the problems of the technologies described above; The assembly and disassembly methods of the present invention during to maintaining fluidized bed drying machine; It mainly comprises the bellows of fluid bed dryer, the suction hood that is positioned at the conduction oil heat exchanger on said bellows top and is positioned at said conduction oil heat exchanger top, and this method comprises the steps:
Step 1, each parts of fluid bed dryer and each pipeline are carried out mark, remove all kinds of flanges and the pipeline that are connected in said conduction oil heat exchanger;
All kinds of steel construction pieces of step 4, dismounting bellows bottom, and at the floor pavement rolling bar;
Step 8, utilize rolling bar that bellows are moved under the conduction oil heat exchanger, fasten and lead chain and drop, promote under bellows to the conduction oil heat exchanger, the connecting bolt of screwing on is removed and is led chain, and bellows install;
All kinds of steel constructions of step 9, recovery, all kinds of flanges of connection, pipeline and bellows bottom are removed jack, suspension hook and are led chain.
Because the assembly and disassembly methods of the present invention during to maintaining fluidized bed drying machine adopted technique scheme, promptly utilizes simple machine, adopt the method for split dismounting to accomplish the maintenance of fluid bed dryer; This method has shortened the dismounting duration greatly, has improved work efficiency, has practiced thrift great amount of manpower and material resources.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description:
Fig. 1 is the structural representation of fluid bed dryer of the present invention.
The specific embodiment
As shown in Figure 1; The assembly and disassembly methods of the present invention during to maintaining fluidized bed drying machine; It mainly comprises the bellows 1 of fluid bed dryer, the suction hood 3 that is positioned at the conduction oil heat exchanger 2 on said bellows 1 top and is positioned at said conduction oil heat exchanger 2 tops, and this method comprises the steps:
Step 1, each parts of fluid bed dryer and each pipeline 6 are carried out mark, remove all kinds of flanges and the pipeline that are connected in said conduction oil heat exchanger;
All kinds of steel construction pieces of step 4, dismounting bellows 1 bottom, and at the floor pavement rolling bar;
Step 8, utilize rolling bar that bellows 1 are moved to the conduction oil heat exchanger 2 times, fasten and lead chain 9 and drop, promote bellows 1 to conduction oil heat exchanger 2 times, the connecting bolt of screwing on is removed and is led chain 9, and bellows 1 install;
All kinds of steel constructions of step 9, recovery, all kinds of flanges of connection, pipeline 6 and bellows 1 bottom are removed jack 7, suspension hook 8 and are led chain 9.
