Abstract
The utility model relates to thermocouple cleaning device, which the thermocouple of the device wears a steel tube outside the protection pipe, which the extendable arm of the electric actuator is used to move the steel tube; a protect box is fixed on the outside of the drum furnace body, the electric actuator is fixed in the box, the thermocouple is fixed on the box. The push end of the steel tube is made into a groove shape. The front end of the extendable arm of the electric actuator is made into a T-shaped and stuck in the steel tube slot. The device can clean the bonding material of the thermocouple head at any time, improve the measurement accuracy.
Description
Technical field
The utility model relates to a kind of thermopair cleaning plant that can clear up the thermopair head glue in the rotary kiln body at any time.
Background technology
Rotary kiln is to produce blast furnace with raw material ball nodulizing and the major equipment of other industrial buildings with cement, needs in the production run accurately to understand in real time and control kiln temperature, in order to avoid temperature is crossed high or low and can not be produced smoothly.Therefore in the rotary kiln body thermopair being housed is used for thermometric.But because the bad or misoperation of material condition, material is often cohered in the thermopair front in the rotary kiln operation process, influences the accuracy of thermocouple measurement temperature.The material that thermopair coheres previously is thick more, and measuring result error is big more, can not reflect kiln temperature really, thereby influences kiln temperature control and operation.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of thermopair cleaning plant, this device can be in the rotary kiln operation process, the glue of thermopair front is clashed in the motion of the steel pipe by being enclosed within thermopair outside, glue is come off from thermopair, thermopair is exposed in the kiln, improves the accuracy of temperature measuring.
The technical scheme that its technical matters that solves the utility model adopts is: steel pipe of thermocouple protection tube outside cover, and the motion of steel pipe promotes with the telescopic arm of electric actuator; External of rotary kiln is fixed a guard box, and electric actuator is fixed in the guard box, and protecting tube also is fixed on the guard box.The grooving shape is made in the promote-side of steel pipe, and the telescopic arm front end of electric actuator makes T shape, and is stuck in the chamfer putting steel tube.
The beneficial effects of the utility model are: can clear up the material in thermopair head bonding at any time, improve the accuracy of measuring.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, glue, 2, the rotary kiln body, 3, the rotary kiln kiln shell, 4, thermopair, 5, guard box, 6, protecting tube, 7, the protection tube fixed screw, 8, steel pipe, 9, telescopic arm, 10, electric actuator, 11, fixed pin.
Embodiment
As shown in fig. 1, it is high temperature resistant and the steel pipe 8 of certain intensity is arranged to be inserted in one in protecting tube 6 outsides cover in the rotary kiln body 2, and the motion of steel pipe 8 promotes with the telescopic arm 9 of electric actuator 10.The grooving shape is made in the promote-side of steel pipe 8, and telescopic arm 9 front ends of electric actuator 10 make T shape, and are stuck in steel pipe 8 grooves.Can promote steel pipe 8 when telescopic arm 9 moves like this.On rotary kiln kiln shell 3, do a fixedly guard box 5, be used to protect steel pipe 8 and electric actuator 10, with two fixed pins 11 electric actuator 10 is fixed on the guard box 5 in addition, guarantee that actuator 10 does not move with telescopic arm 9 in whole operation process.Protecting tube 6 also is fixed on the guard box by protection tube fixed screw 7, and thermopair 4 and protection tube 6 all kept motionless when steel pipe 8 moved like this.
In the rotary kiln operation process, under the opened state of power switch, actuator 10 will move its telescopic arm 9 at regular intervals.When telescopic arm 9 moves forward, promote steel pipe 8, the glue 1 of 8 bumps of steel pipe front, glue 1 comes off from thermopair 4 front ends, and thermopair 4 heads are exposed in the kiln, improves thermopair 4 accuracies of measurement.Telescopic arm 9 is withdrawn after pushing away steel pipe 8 certain distances forward automatically, and drive steel pipe 8 is got back to original position.Certain hour back actuator 10 at interval repeats to do above motion, can clear up the glue 1 on the thermopair 4 at any time.The time interval of telescopic arm 9 motions can be fixed according to actual conditions.
Adopt the thermopair cleaning plant of this spline structure, it is high to handle load, and floor area is little, and equipment is installed simple and easy, simple to operate, and operation maintenance is convenient.
Claims (2)
1, a kind of thermopair cleaning plant comprises protecting tube (6), it is characterized in that: protecting tube (a 6) outside cover steel pipe (8), and the motion of steel pipe (8) promotes with the telescopic arm (9) of electric actuator (10); Rotary kiln body (a 2) guard box of fixed outside (5), electric actuator (10) is fixed in the guard box, and protecting tube (6) also is fixed on the guard box (5).
2, according to the described thermopair cleaning plant of claim 1, it is characterized in that: the grooving shape is made in the promote-side of steel pipe (8), and telescopic arm (9) front end of actuator (10) makes T shape, and is stuck in steel pipe (8) groove.
