Description

Technical Field

[0001] The invention relates to the technical field of industrial kilns, and in particular to a tunnel kiln wall structure with good sealing performance. Background Art

[0002] Ordinary tunnel kilns mostly use refractory bricks and other building materials to build kiln walls. Brick kiln walls are built with bricks. Due to the small size of bricks, there are many mortar joints during construction. It is almost impossible to ensure that the mud in each mortar joint is full during the masonry process. If the mortar joints between bricks are not full, it will lead to poor sealing of the kiln wall, air leakage, and air circulation from the mortar joints, causing abnormalities in the thermal system in the kiln, uneven temperature, and failure to reach the baking temperature of the brick blank, resulting in brick collapse, cracks, mute, black foot bricks, embossing, bread bricks, lime bursts and other defects. In order to solve the above problems and improve the sealing of the kiln wall, an insulation board is usually installed on the outside of the kiln wall to improve the sealing of the kiln wall.

[0003] However, the existing equipment does not have the insulation board with quick disassembly and assembly function. During the subsequent replacement or maintenance, many fixing bolts need to be removed one by one, which is time-consuming and some rusted screws cannot be removed, increasing the difficulty of maintenance. Therefore, a tunnel kiln wall structure with good sealing performance is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a tunnel kiln wall structure with good sealing performance.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a tunnel kiln wall structure with good sealing performance, including a kiln wall body, a plurality of sockets are provided on the front of the kiln wall body, an insulation board is movably provided on the front of the kiln wall body, a plurality of plug blocks are fixedly provided on the side of the insulation board close to the kiln wall body, the plug blocks and the sockets are adapted to each other, two limit seats are fixedly provided on both sides of the kiln wall body, an extrusion structure is provided on one side of the limit seat, limit grooves are provided on the top inner wall and the bottom inner wall of the limit seat, an arc groove is provided on the inner wall of one side of the limit seat, a positioning hole is provided on the arc groove, and two locking structures are fixedly provided on both sides of the insulation board.

[0008] As a further description of the above technical solution:

[0009] The mounting plate is provided with two circular holes, the inner walls of the circular holes are provided with sealing rings, and the inner walls of the sealing rings are movably connected to the sliding rod.

[0010] As a further description of the above technical solution:

[0011] The locking structure includes a connecting frame fixedly installed with the insulation board, a locking block is fixedly provided at one end of the connecting frame, limit strips are fixedly provided at the top and bottom of the locking block, the limit strips and the limit grooves are matched, a storage cavity is provided on the locking block, a second spring is fixedly provided in the storage cavity, a guide plate is fixedly provided at one end of the second spring, the guide plate is movably connected to the inner wall of the storage cavity, a positioning rod is fixedly provided on one side of the guide plate, and the positioning rod is matched with the positioning hole.

[0016] The present invention has the following beneficial effects:

[0017] 1. Compared with the prior art, the tunnel kiln wall structure with good sealing performance is provided with a limit seat, a connecting frame, a locking block, a limit strip, a storage cavity, a second spring, a guide plate and a positioning rod. When disassembly is required, multiple positioning rods are squeezed, and the positioning rods squeeze the guide plate, and the guide plate squeezes the second spring. When one end of the positioning rod is retracted into the arc groove, the insulation board is pulled outward, and the insulation board can be removed for replacement or maintenance. When installing, the four positioning rods are pressed inward to make one end of the positioning rod slide into the arc groove, and then the insulation board is pushed, and the four locking blocks are inserted into the four limit seats. The locking blocks drive the positioning rod to move. When one end of the positioning rod moves to the position of the positioning hole, the second spring pushes the positioning rod out, and the positioning rod is inserted into the positioning hole. The insulation board is installed, replacing the traditional bolt fixing mode and improving the disassembly and assembly efficiency.

[0018] 2. Compared with the prior art, the tunnel kiln wall structure with good sealing performance is equipped with a sliding rod, a mounting plate, a push rod and a first spring. During disassembly, the push rod can be driven by squeezing the mounting plate. The movement of the push rod can squeeze the positioning rod, thereby realizing the disassembly of the insulation board. The squeezing structure is arranged on one side of the limit seat, which can improve the convenience of disassembly and assembly, and does not require the use of other tools for disassembly, thereby improving the practicability of the equipment.
