[0002] Grate cooler is a main equipment in cement production line. It is mainly used for cooling, conveying and heat recovery of cement clinker, providing hot air for rotary kiln and decomposition furnace, etc. It is the main equipment for heat recovery of burning system. The control of its transmission system is related to the stability of the whole production system, and affects the quality of cement and the efficiency of heat recovery.

[0003] The clinker layer thickness is one of the main control parameters in the grate cooler control system. The layer thickness determines the grate speed and affects the operation of the air supply system and the heat recovery efficiency. Therefore, accurate measurement of the layer thickness is of great significance to improving product quality and production efficiency.

[0004] At present, when measuring the thickness of the material layer in the grate cooler, the material layer thickness is mostly estimated by adjusting the speed of the grate cooler according to the wind pressure of each wind chamber. Since the grate plate and wind chamber of the grate cooler will be worn or blocked due to long-term use, the detection accuracy is reduced, and the accuracy of the detection result is reduced;

[0005] Therefore, the present application proposes a grate cooler material layer thickness measuring device. Utility Model Content

[0026] Embodiment 1

[0027] In order to solve the technical problems in the background technology, the following grate cooler material layer thickness measuring device is provided:

[0028] Combination Figure 1-Figure 4As shown, the grate cooler material layer thickness measuring device provided by the utility model comprises a rotating rod 1, which is horizontally and rotatably mounted on a grate cooler body 2, and the rotating rod 1 passes through the interior of the grate cooler body 2, a feed port 21 is provided at one end of the grate cooler body 2, a discharge port 22 is provided at the bottom of the grate cooler body 2 and on a side away from the feed port 21, a grate plate 23 is installed in the grate cooler body 2 and below the feed port 21, and it is specifically explained that: the installation methods of the grate cooler body 2 and the grate plate 23 are both existing structures, which belong to the technical scope familiar to those skilled in the art and are not described in detail here, one end of the grate plate 23 away from the feed port 21 extends to above the discharge port 22; a contact plate 3 is fixedly installed on the rotating rod 1 and located in the grate cooler body 2, and the bottom of the contact plate 3 can contact the top of the grate plate 23, and one side of the grate cooler body 2 A scale 4 is fixedly installed on the outer wall and on one side of the rotating rod 1, and an indicating component 5 is installed on the rotating rod 1 and on the outside of the scale 4. The lowest end of the indicating component 5 and the lowest end of the contact plate 3 are located on the same horizontal plane. Through the design of the contact plate 3, the scale 4 and the indicating component 5, when the grate plate 23 transports cement clinker, the contact plate 3 contacts the top of the cement clinker, and the lowest end of the indicating component 5 and the lowest end of the contact plate 3 are located on the same horizontal plane. The indicating component 5 is used to observe the scale on the scale 4 corresponding to the lowest end of the indicating component 5, thereby realizing the measurement effect of the material layer thickness of the grate plate 23, replacing the measurement method of estimating the material layer thickness according to the wind pressure of each wind chamber by adjusting the speed of the grate cooler, effectively avoiding the wear or blockage of the grate plate 23 and the wind chamber after long-term use, thereby reducing the detection accuracy, thereby improving the accuracy of the detection result.

[0029] Embodiment 2

[0030] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0031] In this embodiment, the indicating assembly 5 includes a connecting rod 51 and an indicating block 52. One end of the connecting rod 51 is fixedly connected to the rotating rod 1. A hinge frame 521 is fixed to the middle position of the top of the indicating block 52. The indicating block 52 is hinged to the other end of the connecting rod 51 through the hinge frame 521. The bottom of the indicating block 52 is horizontal and is located on the same horizontal plane as the lowest end of the contact plate 3. When in use, when measuring the thickness of the cement clinker layer on the grate plate 23, the contact plate 3 contacts the top of the cement clinker. When the thickness of the cement clinker layer changes, the contact plate 3 rotates around the rotating rod 1 so that the bottom of the contact plate 3 maintains contact with the top of the cement clinker, thereby making the connecting rod 51 rotate synchronously around the rotating rod 1 through the rotating rod 1. The indicating block 52 rotates on the connecting rod 51 through the hinge frame 521, so that the bottom of the indicating block 52 remains horizontal, which is beneficial for the staff to observe the corresponding scale on the scale 4.

[0032] In this embodiment, the contact plate 3 includes a vertical plate 31 and a curved plate 32. The vertical plate 31 is fixed on the rotating rod 1, and the curved plate 32 is fixedly installed at the bottom of the vertical plate 31. The lowest end of the curved plate 32 is located on the side of the vertical plate 31 close to the conveying direction of the grate plate 23. The bottom of the indicator block 52 and the lowest end of the curved plate 32 are located on the same horizontal plane. By setting the curved plate 32, when measuring the thickness of the cement clinker layer on the grate plate 23, the curved plate 32 contacts the top of the cement clinker. The lowest end of the curved plate 32 is located on the side of the vertical plate 31 close to the conveying direction of the grate plate 23. When the grate plate 23 conveys cement clinker, it contacts the curved plate 32, which is conducive to the rotation of the curved plate 32 around the rotating rod 1 and improves the detection accuracy.

[0033] Embodiment 3

[0034] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0035] In the present embodiment, a positioning mechanism 6 acting on the rotating rod 1 is installed on the grate cooler body 2, which is used to position or cancel the positioning of the rotating rod 1. Through the design of the positioning mechanism 6, the positioning or canceling effect of the rotating rod 1 is achieved. When there is no need to measure the thickness of the material layer, a force is applied to the rotating rod 1 to make it rotate on the grate cooler body 2, so that the arc plate 32 and the vertical plate 31 rotate around the rotating rod 1, so that the arc plate 32 is away from the grate plate 23, and thus away from the cement clinker on the grate plate 23. At this time, the rotating rod 1 is positioned by the positioning mechanism 6, thereby effectively reducing the wear of the arc plate 32 caused by the movement of the cement clinker. When measuring the thickness of the material layer, the positioning of the rotating rod 1 by the positioning mechanism 6 is canceled. At this time, under the action of the gravity of the arc plate 32 and the vertical plate 31 themselves, the arc plate 32 and the vertical plate 31 can be rotated around the rotating rod 1, so that the arc plate 32 moves downward in an arc to contact the cement clinker.

[0036] In this embodiment, the positioning mechanism 6 includes a mounting shell 61 which is horizontally fixedly mounted on the top of the grate cooler body 2, a limiting rod 62 is fixedly mounted on the rotating rod 1 and located on the side of the connecting rod 51 away from the grate cooler body 2, a sliding rod 63 is mounted on the mounting shell 61 and is slidable along the direction of the limiting rod 62, a limiting plate 64 is fixed on one end of the sliding rod 63 close to the limiting rod 62, a plurality of limiting grooves 641 are provided on the limiting plate 64 and on one side close to the limiting rod 62, the plurality of limiting grooves 641 are arranged in a linear array in the vertical direction, the limiting grooves 641 are inclined and inclined upward along the direction of the limiting rod 62, when in use, when there is no need to measure the thickness of the material layer and to position the rotating rod 1, a force is applied to the limiting rod 62 to make it rotate around the rotating rod 1, The end of the limit rod 62 is thereby caused to move upward in an arc, so that the arc plate 32 is moved away from the grate plate 23, and a force is applied to the limit plate 64 to cause the sliding rod 63 to slide on the mounting shell 61 toward the limit rod 62, so that the limit rod 62 can be inserted into one of the limit grooves 641, so that the limit plate 64 is engaged with the limit rod 62, thereby achieving a limiting effect on the limit rod 62. Conversely, a force is applied to the limit rod 62 to cause it to rotate around the rotating rod 1, so that the end of the limit rod 62 is caused to move upward in an arc, and the limit plate 64 is pushed to cause the sliding rod 63 to slide on the mounting shell 61 away from the limit rod 62, so that the engaging state between the limit plate 64 and the limit rod 62 can be cancelled, thereby canceling the limiting of the rotating rod 1, which is convenient for use.

[0037] In this embodiment, a damping sleeve 631 is fixedly mounted on the sliding rod 63 and sleeved on the outside thereof, and the damping sleeve 631 forms a conflict with the inner wall of the mounting shell 61. By setting the damping sleeve 631, the damping sleeve 631 forms a conflict with the inner wall of the mounting shell 61, thereby increasing the friction between the sliding rod 63 and the mounting shell 61, effectively preventing the sliding rod 63 from sliding naturally on the mounting shell 61.
