[0002] Kiln is a widely used ceramic sintering equipment, which can be used to produce daily-use porcelain, sanitary porcelain, bricks and tiles, electrode materials and other products. Taking the atmosphere protection roller kiln as an example, its basic working principle is: using a motor to drive multiple rows of rollers to rotate, the powder material in the graphite sagger is continuously sent into the closed furnace body of tens of meters, and after high-temperature sintering at about 850℃, it is taken out of the furnace and enters the next process.

[0003] With the improvement of roller kiln design, the length of kiln is increasing. The friction between sagger and roller causes the sagger to deviate from the direction of travel in the furnace, causing collision with the furnace wall and even kiln blocking. The existing correction schemes include installing a guide mechanism on the roller or adjusting the speed and angle of the roller to achieve correction. The former is not conducive to the strength of the roller and causes the roller to break, while the latter has a more complex structure and a high failure rate. Utility Model Content

[0036] The material correction device of the utility model has a driving mechanism 1 arranged outside the furnace body 3, which is not affected by the high temperature and dust environment in the furnace body 3, has high reliability and long service life. The sliding rod 21 extends into the furnace body 3, and can guide the material on the material conveying mechanism 4 in the furnace body 3 to correct the position. Compared with the current method of correcting by installing a guiding mechanism on the roller or adjusting the speed and angle of the roller, it will not affect the structural strength of the roller, nor will it increase the structural complexity too much.

[0037] In one embodiment, the sliding rod 21 is sealingly slidably arranged on the furnace wall of the furnace body 3. Such an arrangement can ensure the sealing of the furnace body 3 on the one hand, and on the other hand, it can prevent the high-temperature gas of the furnace body 3 from flowing out of the through hole 31 of the furnace wall to affect the driving mechanism 1.

[0038] In one embodiment, the correction mechanism 2 further includes a sliding sealing sleeve 23, and the sliding sealing sleeve 23 is used to slide and seal the sliding rod 21 on the through hole 31;

[0039] The sliding sealing sleeve 23 is fixed in sealing and sliding cooperation with the sliding rod 21, and the sliding sealing sleeve 23 is sealed and fixedly arranged on the through hole 31 of the furnace wall of the furnace body 3.

The sliding rod 21 is slidably provided in the sleeve 231 and the sliding hole I 331. In this embodiment, the cooperation between the sliding sealing sleeve 23 and the sliding rod 21 and the furnace body 3 is facilitated, and the installation difficulty is simplified. Preferably, a dust ring 27 is also provided on the sliding hole I 331 to prevent dust in the furnace body 3 from affecting the sliding hole I 331.

[0041] In one embodiment, the driving mechanism 1 is a linear driving mechanism, which is used to drive the sliding rod 21 to perform linear reciprocating movement, and the linear driving mechanism can be a linear driving mechanism such as a linear module, an electric cylinder, a hydraulic cylinder, a sprocket chain, etc.;

[0042] The driving mechanism 1 is arranged parallel to the sliding rod 21, and the output end of the driving mechanism 1 and the sliding rod 21 are connected via a connecting plate 26. At this time, the sliding rod 21 and the driving mechanism 1 are arranged parallel to each other, which can save installation space and improve structural compactness.

[0048] The correction plate 22 can enter and leave the conveying area of ​​the material conveying mechanism 4. When the correction plate 22 enters the conveying area of ​​the material conveying mechanism 4, the material will be guided by the correction plate 22 to adjust the position of the material on the material conveying mechanism 4 during the movement of the material through the material conveying mechanism 4, thereby facilitating the subsequent accurate conveying or unloading of the material and avoiding kiln blockage accidents caused by material deviation.

[0049] In one of the embodiments, the inner wall of the furnace body 3 is provided with a heat-insulating layer 5, and the heat-insulating layer 5 is provided with a sliding hole II51 for the sliding rod 21 to slide and a receiving groove 52 for accommodating the correction plate 22. By providing the heat-insulating layer 5, the heat-insulating effect of the furnace body 3 can be improved, and by providing the sliding hole II51 and the receiving groove 52, the heat-insulating layer 5 can be prevented from affecting the operation of the material correction device. By providing the receiving groove 52, when the material correction device does not need to perform correction work, the correction plate 22 can be embedded in the receiving groove 52. On the one hand, it can prevent the correction plate 22 from affecting the normal transportation of the material, and on the other hand, it can make up for the vacancy formed by the receiving groove 52 and the sliding hole II51 provided on the heat-insulating layer 5, thereby ensuring the heat-insulating effect. Figure 7 In a preferred embodiment, the sliding hole II 51 is clearance-matched with the sliding rod 21 , so as to further ensure the heat preservation effect of the heat preservation layer 5 .

[0050] In one embodiment, a set of material correction devices is provided on the corresponding two sides of the side wall of the furnace body 3. By symmetrically arranging two sets of material correction devices, it is possible to correct the material to the middle of the material conveying mechanism 4. For example, when the material passes through the action range of the two sets of material correction devices, the correction plates 22 of the two sets of material correction devices are synchronously driven to move the material to the middle of the material conveying mechanism 4. Of course, the material can also be corrected to one side or a specific position of the material conveying mechanism 4 by separately controlling the driving mechanisms 1 of the two sets of material correction devices.

[0051] The above is only an embodiment and does not limit the present invention in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the present invention without departing from the scope of the present invention by using the above disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
