Description
Technical field
The utility model relates to cement field, particularly relates to a kind of rotary kiln tertiary air temperature thermocouple device.
Background technology
Produce on cement producing line at new dry process, in the use procedure of rotary kiln tertiary air temperature thermocouple, owing to using 100% carbide mud residue ingredient, in calcination process, grog blown sand is larger, tertiary air point for measuring temperature wind speed is very fast, temperature higher (950-1050 DEG C), the high speed winds with particulate material is flushed on thermocouple, causes thermocouple serious wear.The thermocouple at every turn changed is all because dust storm washes away and causes thermocouple overcoat to gall, and is burnt out by internal thermal resistance silk.Life-span on average often props up and is no more than 4 days, not only increases the workload of maintenance but also has a strong impact on technology controlling and process, increases operation easier, increases producing cost.
Current cement industry; particularly can not get effective solution the service life of 100% carbide slag cement industry tertiary air temperature thermocouple; of long duration not only increase production cost; and the damage of point for measuring temperature often can have influence on the normal operating of kiln system, the service life of tertiary air temperature thermocouple annoyings whole cement industry always.
Utility model content
The utility model, in order to solve short problem in tertiary air temperature thermocouple service life, provides a kind of rotary kiln tertiary air temperature thermocouple device, this device for prolonging tertiary air temperature thermocouple service life.
The purpose of this utility model is realized by following technical proposals.
A kind of rotary kiln tertiary air temperature thermocouple device, comprise tertiary-air pipe, and the tertiary air damper valve be arranged in tertiary-air pipe, tertiary-air pipe on rear side of described tertiary air damper valve is provided with the thermocouple extending to tertiary-air pipe inner chamber, thermocouple is fixed on the thermocouple mouth of pipe by set screw, is provided with the thermal resistance wire for thermometric in thermocouple.
Preferably, described tertiary-air pipe adopts steel pipe material, is enclosed with refractory brick outside steel pipe.
Preferably, described tertiary air damper valve is fixed by tertiary air damper shell body, and tertiary air damper valve also extends to tertiary-air pipe inner chamber.
Preferably, described tertiary air damper valve and thermocouple distance are 1 ~ 1.2 meter.
Compared with prior art, the beneficial effects of the utility model are: this device solves short problem in the tertiary air thermometric torrid zone even service life, also solves the problem because long-term lopsided wear causes thermocouple overcoat not make full use of.Tertiary air temperature thermocouple is made to also improve production environment while prolongation service life.Lay a good foundation for grate-cooler in cement system cleans low cost movement.
In production practices, reduce the labour intensity of employee, decrease the loss of spare part, reduce the operating cost of equipment.

Fig. 3 is the thermocouple making after transformation to damage.
In figure: 1-tertiary-air pipe; 2-refractory brick; The 3-thermocouple mouth of pipe, DN35; 4-thermal resistance wire, 5-thermocouple, 6-tertiary air damper shell body, 7-tertiary air damper valve, 8-with the hot blast of the grains of sand, 9-set screw.
Detailed description of the invention
Below in conjunction with accompanying drawing to and embodiment be described further this use is novel.
As shown in Figure 1, this rotary kiln tertiary air temperature thermocouple device, comprise tertiary-air pipe 1, and the tertiary air damper valve 7 be arranged in tertiary-air pipe 1, tertiary-air pipe 1 on rear side of tertiary air damper valve 7 is provided with the thermocouple 5 extending to tertiary-air pipe 1 inner chamber, thermocouple 5 is fixed on the thermocouple mouth of pipe 3 by set screw 9, is provided with the thermal resistance wire 4 for thermometric in thermocouple 5.Tertiary-air pipe 1 adopts steel pipe material, is enclosed with refractory brick 2 outside steel pipe.Tertiary air damper valve 7 is fixed by tertiary air damper shell body 6, and tertiary air damper valve 7 also extends to tertiary-air pipe 1 inner chamber.
In real work, tertiary-air pipe 1 is operate under negative pressure (about-500pa), high temperature (about 900 DEG C), its diameter is 2.7 meters, inside studs with the thick refractory brick of 200mm 2, and thermocouple 5 is 1 ~ 1.2 meter apart from slide valve 7, after thermocouple 5 is fixed on slide valve 7, and fixed cover is on steel pipe 3, steel pipe 3 length is 20cm, and the hot blast 8 with the grains of sand can not directly be flushed on thermocouple 5, and the direction windward of the lower watchcase of thermocouple 5 can not be caused to be washed very soon.As shown in Figure 1, in addition, transform through position, set screw 9 installed by the steel pipe 3 installing thermocouple 5, set screw 9 was unclamped in every 2 hours when post personnel patrol and examine, thermocouple 5 is turned clockwise 45 degree, then fastening set screw 9, reach being flushed in the outer of thermocouple 5 uniformly putting containing husky wind 8 of high-speed and high-temperature.The service life reaching thermocouple extends, make the thermocouple 5 damaged as shown in Figure 3 after transformation, and make the thermocouple schematic diagram damaged before Figure 2 shows that transformation, after transformation, the wear area of thermocouple increases, the intensity of wearing and tearing reduces, and extends the service life of thermocouple 5 greatly.
This programme adopts two steps to transform:
1, thermocouple is changed into after slide valve by what originally designed before slide valve; Because high speed dust storm is inevitable to washing away of thermocouple; obstacle is not had to protect thermocouple, when point for measuring temperature is changed into after slide valve, due to the effect of slide valve; high speed dust storm in the past, plays a protective role to the thermocouple of ensconcing after slide valve bottom slide valve.
2, thermocouple diameter is
be often 200mm with one, diameter is
steel-pipe welding in the position of plug in thermocouple, in the middle part of steel pipe, open one
hole, outside hole, weld the nut of a M12, thermocouple inserted in steel pipe, nut is twisted the screw of a M12x30mm, thermocouple is fixed on steel pipe.Require during normal operation that post is unclamped screw when every two hours patrolling and examining, turn clockwise thermocouple after 45 ° holding screw stationary heat galvanic couple again.
This device and method of operating, every two hours rotated 45 ° when thermocouple runs, and thermocouple head is evenly washed away under high speed dust storm, reaches the object of the prolongation in service life extending thermocouple.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that detailed description of the invention of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to the utility model and be determined by submitted to claims.Scope of patent protection.
