[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 The utility model discloses a kiln inlet lifting device, comprising a high-temperature kiln 1, a kiln inlet 11 being provided in front of the high-temperature kiln 1, a sealing assembly being provided at the front side of the high-temperature kiln 1, the sealing assembly comprising a sealing door 2 installed at the front end of the kiln inlet 11, a door frame 3 being provided at the front side of the sealing door 2, a squeezing seat 31 being provided on the door frame 3, the sealing door 2 being slidably installed on the squeezing seat 31, an inclined downslope 311 and an upslope 312 being provided inside the squeezing seat 31, a fixing block 21 being provided at the front end of the sealing door 2, the upper and lower surfaces of the fixing block 21 being respectively adapted to the downslope 311 and the upslope 312, and a supporting pad 4 being provided at the front side of the kiln inlet 11;

[0024] After the refractory bricks are placed in the high-temperature kiln 1, the sealing door 2 is lowered on the door frame 3 until it contacts the supporting pad 4, and the sealing door 2 stops descending. At this time, the supporting pad 4 supports the sealing door 2, and the squeezing seat 31 continues to descend. The downward slope 311 is separated from the fixed block 21, and the upward slope 312 contacts the fixed block 21. Since the sealing door 2 no longer descends at this time, the upward slope 312 pushes the fixed block 21 to move toward the high-temperature kiln 1, so that the sealing door 2 is further in contact with the high-temperature kiln 1, thereby improving the sealing effect of the sealing door 2 on the high-temperature kiln 1, avoiding the escape of high-temperature airflow inside the high-temperature kiln 1, improving the heating effect inside the high-temperature kiln 1, and ensuring the safety around the high-temperature kiln 1.

[0025] The squeezing seat 31 is hollow, which facilitates the sliding of the fixed block 21 in the squeezing seat 31. A limiting baffle 313 is provided on the rear side of the squeezing seat 31, and a limiting plate 211 is provided on the front side of the fixed block 21. The limiting baffle 313 is adapted to the limiting plate 211 to prevent the fixed block 21 from detaching from the squeezing seat 31.

[0026] A sliding groove 314 is provided on the front side of the squeezing seat 31, and a slider 32 is slidably installed in the sliding groove 314. The slider 32 is connected to the fixed block 21 through an elastic member 33. The elastic member 33 is preferably a spring. The elastic member 33 is always in a compressed state and contacts the fixed block 21, so that the fixed block 21 is in a vertical state when the squeezing seat 31 slides and does not deviate or tilt forward and backward, so that the fixed block 21 will not drive the sealing door 2 to deviate and tilt forward and backward, so that the sealing door 2 can better fit together with the periphery of the kiln inlet 11, further ensuring the sealing of the kiln inlet 11.

[0027] A driving hydraulic cylinder 34 is installed on the door frame 3, and the other end of the driving hydraulic cylinder 34 is fixedly connected to the squeezing seat 31. The driving hydraulic cylinder 34 drives the squeezing seat 31 to move up and down. The squeezing seat 31 contacts the fixed block 21 through the upslope surface 312, driving the fixed block 21 to move toward the high-temperature kiln 1. The fixed block 21 drives the sealing door 2 to move and fit closely to the kiln inlet 11, ensuring the sealing of the high-temperature kiln 1, preventing the escape of high-temperature airflow inside the high-temperature kiln 1, and improving the safety of the equipment.

[0028] A thermocouple 12 is installed on the high-temperature kiln 1. The thermocouple 12 is used to monitor the temperature inside the high-temperature kiln 1 in real time, making it convenient for the operator to detect and adjust the temperature inside the high-temperature kiln 1, thereby improving the heating effect of the high-temperature kiln 1. A heating wire 13 is installed inside the high-temperature kiln 1 for directly heating the objects inside the high-temperature kiln 1.

[0029] In the present invention, the hydraulic cylinder 34 is driven to drive the squeezing seat 31 to move up and down, and the sealing door 2 is lowered on the door frame 3 until it contacts the support pad 4, and the squeezing seat 31 continues to descend, and the downslope surface 311 is separated from the fixed block 21. The squeezing seat 31 contacts the fixed block 21 through the upslope surface 312, driving the fixed block 21 to move toward the high-temperature kiln 1. The fixed block 21 drives the sealing door 2 to move and fit closely to the kiln inlet 11, thereby avoiding the escape of high-temperature airflow inside the high-temperature kiln 1, improving the heating effect inside the high-temperature kiln 1, and ensuring the safety of the surrounding area of ​​the high-temperature kiln 1.
