Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings. In the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.

In the technical solutions of the present invention, unless otherwise specifically stated, the terms "mounting", "setting", "connecting", "fixing", and the like should be interpreted broadly, and may be interpreted as fixed connection or detachable connection, and the specific meanings of the above terms may be understood by those skilled in the art according to the specific situations involved in the technical solutions.

The first embodiment:

the high-temperature lens protection device for the kiln head of the cement kiln shown in fig. 1 to 3 comprises an outer cylinder wall 1 and an inner cylinder wall 2 which are coaxial from outside to inside and are arranged at a certain distance from each other, wherein a gap formed between the outer cylinder wall 1 and the inner cylinder wall 2 provides a flowing space for fluid with a cooling effect. Two ends of the outer cylinder wall and the inner cylinder wall are provided with a first end cover 3 and a second end cover 4 which are annular, two air pipes 301 for fluid to enter and exit are arranged at the symmetrical positions of the first end cover 3, and a plurality of through holes 401 which are uniformly distributed are arranged on the second end cover 4.

The relative position between the outer cylinder wall 1 and the inner cylinder wall 2, that is, as shown in fig. 4, a partition plate 5 is arranged on the same diameter to axially divide the space between the outer cylinder wall and the inner cylinder wall into two parts which are symmetrical up and down, and a hemispherical first cover body 6 and a hemispherical second cover body 7 made of high temperature resistant glass are arranged on the outer side of the second end cover 4 and are respectively connected with the outer cylinder wall 1 and the inner cylinder wall 2, wherein the high temperature resistant glass is selected and customized by a person skilled in the art according to the temperature in the head of the cement kiln. With the above arrangement, when a fluid, such as air, having a cooling effect enters the space between the outer cylinder wall 1 and the inner cylinder wall 2 from the upper air pipe 301 in the direction of the arrow shown in fig. 5, the fluid flows through the gap between the first cover 6 and the second cover 7 through the through hole 401 in the direction of the arrow and finally flows out from the lower air pipe, i.e., the air pipe 301 on the other side. The air protection device flows in the direction indicated by the arrow, so that heat can be taken away, a cooling effect is achieved, and the high-temperature lens in the protection device is protected. In order to increase the cooling effect, the introduced fluid can adopt high-pressure air, and the flow speed of the fluid is accelerated by the high-pressure air to improve the cooling effect. In addition, the introduced fluid can also adopt distilled water with lower temperature, and the distilled water is adopted mainly in consideration of the fact that the distilled water does not contain impurities, so that the service life of the first cover body and the second cover body is not influenced.

To facilitate the installation of the high temperature lens, as shown in fig. 1, the inner diameter R1 of the first end cap 3 is smaller than the inner diameter R2 of the inner cylindrical wall 2, so that the installation hole 302 shown in fig. 2 can be provided at the inner edge of the first end cap 3.

The second embodiment:

on the basis of the first embodiment, in consideration of the fact that the high-temperature lens protection device is easily damaged by the first cover body 6 and the second cover body 7 made of glass materials due to collision when being inserted into a high-temperature lens installation opening on a kiln door of a kiln head cover, the guide protection sleeve 8 shown in fig. 6 is arranged outside the outer cylinder wall 1, guide rails 801 are axially arranged on two opposite sides of the inner wall of the guide protection sleeve 8, a first limiting block 802 used for preventing the first cover body 6 from excessively extending into the kiln is arranged on one side of the guide rails 801 close to the first cover body 6, sliding blocks 101 capable of sliding along the guide rails 801 are arranged on two opposite sides of the outer cylinder wall 1, and an annular third end cover 803 is arranged at one end, far away from the first cover body 6, of the guide protection sleeve 8. In order to enable the first cover 6 to completely extend out of the guiding protective sleeve 8 and prevent the outer cylinder wall 1 from being pulled out of the guiding protective sleeve 8, when the protective device is in the state shown in fig. 6, namely when the left side of the first cover 6 is flush with the left end of the guiding protective sleeve 8, the distance between the sliding block 101 and the first limiting block 802 is greater than the radius of the hemispherical first cover 6.

The length L2 of the outer cylinder wall 1 is greater than the length L1 of the guiding sheath 8, so that when the first housing 6 is inside the guiding sheath 8 as shown in fig. 6, the length of the outer cylinder wall 1 outside the guiding sheath 8 is greater than the radius of the circular first housing 6. Through this kind of setting, can be convenient for realize stretching out first cover body 6 completely by the inside of direction protective sheath 8 through promoting the urceolus wall, make the direction protective sheath can not exert an influence to the field of vision of high temperature camera lens.

When the high-temperature lens protection device is used, high-pressure air is introduced into the high-temperature lens protection device comprising the guide protection sleeve 8, then the high-temperature lens protection device is inserted into a high-temperature lens installation opening on a kiln door through an external transmission device connected with the high-temperature lens protection device, finally the outer cylinder wall 1 is pushed, so that the first cover body 6 is completely extended into the kiln through the guide protection sleeve 8, and the high-temperature lens in the first cover body and the second cover body can observe the interior of the kiln. After shooting is finished, the outer cylinder wall 1 is pulled, the end part of the first cover body 6 returns to the guide protective sleeve 8, and then the high-temperature lens protection device is integrally taken out.
