Abstract
The utility model relates to a tool special for disassembling thermoelectric couples of a catalytic cracking raising pipe. Handles are arranged on the circumference of the outer side wall of a flange plate; when the thermoelectric couples are disassembled, the flange plate is connected with flange plates of the thermoelectric couples by using a screw; stress application rods are arranged on the handles; and the stress application rods are rotated, and the thermoelectric couples can be disassembled easily, and more than 1 hour is needed to disassemble a thermoelectric couple, so that the technical problem about thermoelectric couple disassembling is solved, and the efficiency is improved by more than 8 times. Compared with the conventional chain guiding tool for disassembling the thermoelectric couples of the catalytic cracking raising pipe, the tool has the advantages of reasonable design, simple structure, labor conservation, time conservation, high disassembly speed and the like, and can be used for disassembling the thermoelectric couples of the catalytic cracking raising pipe.
Description
Technical field
The utility model belongs to the tool equipment technical field, is specifically related to be used to dismantle the instrument of the thermocouple of catalytic cracking riser.
Background technology
Heavy oil catalytically cracking equipment is the main means of secondary operations in China's oil refining apparatus; Along with the increase of raw material poor qualityization and heavy oil ratio in recent years; Demonstrating the critical positions of heavy oil catalytically cracking equipment at oil plant more, is the capital equipment in the oil plant oil refining process.Catalytic cracking riser is the equipment that is used to reduce catalytic cracking unit mixer catalyst contact temperature; In order to detect the temperature in the catalytic cracking riser; At riser 12 thermocouples are installed on catalytic cracking riser, the long 800mm of thermocouple, diameter are 40mm.Oil plant needs to need in 2～3 years stop production to overhaul once to refine oil all equipment on the production line, and the repair time reaches 1 month, needs all thermocouples on the dismounting and change catalytic cracking riser during maintenance; The dismounting thermocouple is a difficult point for many years; Because at sedimentation wall and vault, and stripping section all might produce the hard coke button of large block compact, thermocouple in coke button by stuck firmly; Can not dismantle, seriously influence the maintenance progress.
At present, the main tool of dismounting thermocouple be adopt lead chain with thermocouple toward going out to draw, very difficulty is torn open; The speed of dismounting is very slow, can only dismantle 1 thermocouple in one day, blue dish of dismounting in several days sometimes and thermocouple; Tangible dismounting is not got off, and adopts the method for cutting off that thermocouple is cut away at last, has both wasted great amount of time; Waste of manpower has again damaged the substrate of catalytic cracking riser, has improved the apparatus maintenance expense greatly.
At oil refining enterprise, the urgent technical problem that solves of current need provides the instrument of thermocouple on the fast quick-detach catalytic cracking riser of a kind of ability.
Summary of the invention
The utility model technical problem to be solved is to overcome the shortcoming of the thermocouple used tool of above-mentioned dismounting catalytic cracking riser, and a kind of reasonable in design, simple in structure, laborsaving, the fireballing catalytic cracking riser thermocouple dismounting of dismounting specific purpose tool is provided.
Solving the problems of the technologies described above the technical scheme that is adopted is: the lateral wall circumference of ring flange is provided with handle.
The handle that is provided with on the ring flange lateral wall circumference of the utility model has 4, and the angle between the center line of the center line of a handle and an adjacent handle is 90 °.
Be processed with on the same circumference on the ring flange of the utility model with thermocouple flange dish on bolt hole number, aperture and the hole heart apart from identical hole.
The utility model is employed in and is processed with coupling bolt hole on the ring flange, is welded with handle on the excircle of ring flange, during the dismounting thermocouple; Screw rod is penetrated in the hole of ring flange and thermocouple flange dish, ring flange is connected with thermocouple flange dish, boosting-rod is installed on handle with screw rod; Rotate boosting-rod, be easy to thermocouple is taken off, 1 thermocouple of every dismounting needs more than 1 hour; Solved the technical problem of thermocouple dismounting, effect has improved more than 8 times.The utility model is compared with the used chain extracting tool of leading of existing dismounting thermocouple, have reasonable in design, simple in structure, laborsaving, save time, advantage such as dismounting speed is fast, can be used for dismantling the thermocouple of catalytic cracking riser.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
To the utility model further explain, but the utility model is not limited to these embodiment below in conjunction with accompanying drawing and embodiment.
In Fig. 1, the catalytic cracking riser thermocouple of present embodiment dismounting specific purpose tool is made up of ring flange 1, handle 2 connections.
On same circumference on the ring flange 1, be processed with 8 bolts hole; The number of the bolt hole on the aperture of 8 bolts hole and hole heart distance and the thermocouple flange dish, aperture, the hole heart are apart from identical; Bolt hole is used for when the dismounting thermocouple; Link with thermocouple through the ring flange 1 of bolt, be convenient to thermocouple is extracted in catalytic cracking riser the utility model.On the lateral wall circumference of ring flange 1, be uniformly distributed with welding and be connected with 4 handles 2; Angle between the center line of the center line of a handle 2 and an adjacent handle 2 is 90 °; When handle 2 is used to use the utility model dismounting thermocouple, on handle 2, boosting-rod is installed, is increased moment; With thermocouple loosening after; Make thermocouple also and then rotate, the thermocouple of rotation is no longer stuck by fine and close hard coke button in the catalytic cracking riser, and the utility model is easy to thermocouple is extracted in catalytic cracking riser.The thermocouple dismounting specific purpose tool of this structure; From catalytic cracking riser dismounting thermocouple the time, laborsaving, save time, dismounting speed is fast, 1 thermocouple of every dismounting needs more than 1 hour; Solved the technical barrier of thermocouple dismounting; Effect has improved more than 8 times, compares with the used chain instrument of leading of existing dismounting thermocouple, have reasonable in design, simple in structure, laborsaving, save time, advantage such as dismounting speed is fast.
