Abstract
The utility model discloses a cooling protector of a rotary kiln non-contact temperature measuring instrument. The cooling protector of the rotary kiln non-contact temperature measuring instrument comprises a collimation pipe (1), a connection flange (3), a vacuum protection sleeve pipe (3), a Y-shaped pipe (4) and a rear cover (5). The non-contact temperature measuring instrument (6) is installed in the vacuum protection sleeve (3) and a measuring lens of the non-contact temperature measuring instrument faces one side of the collimation pipe (1). The end, adjacent to the lens of the non-contact temperature measuring instrument (6), of the collimation pipe (1) is provided with a compressed air channel. According to the cooling protector of the rotary kiln non-contact temperature measuring instrument, after compressed air is introduced into the collimation pipe, positive pressure can be kept constantly in the collimation pipe. Materials or air in a kiln is effectively prevented from burning the non-contact temperature measuring instrument through the collimation pipe. The compressed air will blow the entire collimation pipe and prevent ash accumulation so as to ensure smoothness of the whole measuring optical path. The compressed air can blow the collimation pipe and the vacuum protection sleeve pipe at the same time and play a good role of cooling.
Description
Technical field
The utility model relates to a kind of protective device of contactless temperature-measuring instrument, specifically is a kind of Cooling protector of rotary kiln contactless temperature-measuring instrument, is applicable to rotary kilns such as cement kiln, limekiln and chemical metallurgy kiln.
Background technology
In many production industries such as building materials, metallurgy, chemical industry, environmental protection, use revolving drum equipment that solid material is carried out machinery, physical or chemical treatment widely, this kind equipment is called as rotary kiln.
Temperature of charge is significant to the normal operating of rotary kiln in the rotary kiln.But rotary kiln temperature is very high, generally between 1200-1700 ℃, therefore can not adopt contact type measurement instrument such as thermocouple to measure, and can only adopt contactless temperature-measuring instrument such as infrared radiation thermometer to measure.
As shown in Figure 1; the contactless temperature-measuring instrument is accurate electronic instrument, and the environment temperature of its work is general only below 70 ℃, therefore; contactless temperature-measuring instrument 7 generally is installed in outside the kiln; be connected by aiming tube 10 on the kiln hood cover 9 of rotary kiln 8, existing contactless temperature-measuring instrument is subjected to that rotary kiln is thermal-radiating to be influenced; contactless temperature-measuring instrument position temperature is still very high; be approximately 200-300 ℃, therefore need to be equipped with cooling device, protect the contactless temperature-measuring instrument.
Rotary kiln is generally negative pressure, and material or hot-air can not enter aiming tube.But when unusual service condition, may transfer pressure-fired to, thereby cause occurring the situation of flame, namely the material of high temperature or air make device damage by aiming tube calcination contactless temperature-measuring instrument in the kiln.Therefore, for protection contactless temperature-measuring instrument, at the aiming tube head, need to install resistant to elevated temperatures quartz window.But the dust in the rotary kiln is very serious, and dust is easy to be adsorbed on quartz window, thereby influences the measurement light path of contactless temperature-measuring instrument, makes to measure to be forbidden.And, because aiming tube is welded on the rotary kiln, when ordinary production, can't clears up the dust stratification of quartz window, thereby significantly influence the normal use of contactless temperature-measuring instrument.
The utility model content
In order to solve the above-mentioned technical problem that exists in the prior art; the utility model provides a kind of Cooling protector of rotary kiln contactless temperature-measuring instrument; comprise aiming tube; adpting flange; the vacuum protection sleeve pipe, Y-piece and bonnet, described contactless temperature-measuring instrument are installed in the described vacuum protection sleeve pipe; it measures camera lens towards described aiming tube one side, and described aiming tube is provided with compressed air channel near an end of described contactless temperature-measuring instrument camera lens.
Further, described aiming tube one end is welded on the rotary kiln, and the other end is connected with the vacuum protection sleeve pipe by described adpting flange.
Further, the length of described aiming tube is between 0.2-0.4 rice.
Further, described vacuum protection sleeve pipe is the stainless steel sleeve pipe that has vacuum interlayer.
Further, described vacuum protection sleeve pipe is provided with the compressed air inlet passage near an end of described contactless temperature-measuring instrument camera lens, and the other end is provided with the compressed air outlet passage.
Further, described vacuum protection sleeve pipe one end is connected with aiming tube by adpting flange, and the other end is connected with described bonnet by bolt.
Further, an end of described Y-piece is connected with the external compression air hose, and the other end is connected to the compressed air channel of described aiming tube, and the 3rd end is connected with the compressed air inlet passage of described vacuum protection sleeve pipe.
The Cooling protector of rotary kiln contactless temperature-measuring instrument of the present utility model has following beneficial effect: one, after compressed air feeds aiming tube, can guarantee to remain in the aiming tube malleation, can effectively avoid the interior material of kiln or air by aiming tube calcination non-contact temperature measuring instrument; Its two, compressed air can purge whole aiming tube, avoids dust stratification, keeps whole measurement light path unobstructed; Its three, compressed air purges aiming tube and vacuum protection sleeve pipe simultaneously, can play the good effect of cooling.Simultaneously, the technical program need not adopt resistant to elevated temperatures quartz glass and water cooling plant, has reduced the manufacturing cost of equipment.

Fig. 1 is contactless temperature-measuring instrument scheme of installation;
Fig. 2 is the structure chart of the Cooling protector of rotary kiln contactless temperature-measuring instrument of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, the Cooling protector of rotary kiln contactless temperature-measuring instrument of the present utility model comprises aiming tube 1, adpting flange 2, and vacuum protection sleeve pipe 3, Y-piece 4 and bonnet 5, all parts are stainless steel.Contactless temperature-measuring instrument 6 is installed in the vacuum protection sleeve pipe 3, and it measures camera lens towards aiming tube 1 one sides.
Vacuum protection sleeve pipe 3 is provided with the compressed air inlet passage for having the stainless steel sleeve pipe of vacuum interlayer at the end near contactless temperature-measuring instrument 6 camera lenses, is provided with the compressed air outlet passage at the other end.Vacuum protection sleeve pipe 3 one ends are connected with aiming tube 1 by adpting flange 2, and the other end is connected with bonnet 5 by bolt.
One end of Y-piece 4 is connected with the external compression air hose, and the other end is connected to the compressed air channel of aiming tube 1, and the 3rd end is connected with the compressed air inlet of vacuum protection sleeve pipe 3.The compressed air that comes from the outside enters into Y-piece 4 by the external compression air hose, enters aiming tube 1 and vacuum protection sleeve pipe 3 respectively.
After compressed air should keep certain flow velocity to feed aiming tube, enough high with malleation in the maintenance aiming tube, could effectively avoid the interior material of kiln or air by aiming tube calcination contactless temperature-measuring instrument.Generally speaking, flow velocity should be between 50-200L/min.Under this flow velocity, the malleation in the aiming tube 1 is enough high, can guarantee the cooling effect of temperature measurer too.
