Description

Technical Field

[0001] The utility model relates to the technical field of glass kiln auxiliary equipment, in particular to a device for replacing kiln sealing bricks. Background Art

[0002] The feeding of electronic glass furnace is generally carried out by a spiral feeder. The feeding port is sealed with a sealing brick with a square outside and a round inside. The feeder pushes the batch material into the furnace through the hole in the middle of the sealing brick.

[0003] Since the sealing bricks are located at the interface between hot and cold and are eroded by the batch materials for a long time, they will be corroded and damaged after a period of use. New feeding port sealing bricks need to be replaced regularly. However, due to the high temperature of the sealing bricks and the small working space, it is difficult to remove the sealing bricks smoothly in the hot state, which brings difficulties to production and maintenance. Utility Model Content

[0004] The purpose of the utility model is to provide a device for replacing kiln sealing bricks to overcome the problems existing in the prior art. The utility model pulls the sealing bricks out of the feeding mouth body by a push-pull screw, and then uses a lifting device to lift the sealing bricks through the lifting ears to complete the disassembly process of the kiln feeding mouth sealing bricks in a hot state, which can improve the convenience of replacing the sealing bricks and solve the problem of difficulty in replacing the sealing bricks in a hot state.

[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:

[0006] A device for replacing kiln sealing bricks comprises a sealing brick frame mounted on a feeding cavity, rigid ears mounted on both sides of the sealing brick frame, and a lifting ear mounted on the top of the sealing brick frame; a support frame is mounted on the bottom of the feeding cavity, a push-pull screw rod is passed through the upper end of the support frame, a flange is provided at the rear end of the push-pull screw rod, and the front end of the push-pull screw rod is connected to the rigid ears;

[0007] Furthermore, the sealing brick frame is mounted on the outer contour of the sealing brick;

[0008] Furthermore, the rigid ear is provided with a threaded hole that cooperates with the push-pull screw;

[0009] Furthermore, the support frame is L-shaped;

[0010] Furthermore, the lower end of the support frame is mounted on the kiln steel structure;

[0011] Furthermore, there are two support frames;

[0012] Furthermore, an open long hole is provided at the upper end of the support frame;

[0013] Furthermore, the rear end of the push-pull screw is installed in the open elongated hole;

[0014] Furthermore, the width of the open elongated hole is greater than the diameter of the push-pull screw;

[0015] Furthermore, the flange is cylindrical, and the diameter of the flange is larger than the diameter of the push-pull screw.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The utility model provides a device for replacing kiln sealing bricks. The sealing bricks are pulled by remotely operating a push-pull screw, which reduces the need for operators to directly contact high-temperature components, prevents burns caused by direct operation of the sealing bricks in a high-temperature environment, greatly reduces operational risks, and improves work safety. The push-pull screw can be used to easily pull the sealing bricks out of the feeding cavity, and then quickly lift them up with the help of lifting ears using a lifting device and replace them with new sealing bricks, greatly shortening the replacement time and improving production efficiency. Directly replacing the sealing bricks in a hot state is not only difficult to operate, but also easily causes damage to the sealing bricks, increasing replacement costs. The optimized design of the device reduces physical damage to the sealing bricks during the replacement process, extends the service life of the sealing bricks, and thus reduces maintenance costs. The sealing bricks are an important component of the kiln feeding cavity, and their sealing performance directly affects the operating efficiency and product quality of the kiln. The device ensures that the sealing bricks can maintain good integrity during the replacement process, helps to maintain or improve the sealing performance of the kiln, and reduces heat loss and environmental pollution. The device has a simple structure and is easy to operate. It is not only suitable for kilns of different models and specifications, but can also be used in other industrial equipment that requires regular replacement of high-temperature components, and has high versatility and adaptability.

[0018] Furthermore, by tightly combining the sealing brick frame with the sealing brick, when replacing the sealing brick, the entire sealing brick can be moved simply by operating the sealing brick frame, which simplifies the replacement process, reduces the operating steps, and improves replacement efficiency.

[0019] Furthermore, the threaded connection can provide efficient transmission force, so that the push-pull screw can easily transmit the thrust to the sealing brick frame when rotating, and then pull the sealing brick in and out of the feeding cavity, which helps to achieve a fast and stable replacement process and improves work efficiency; the rigid ear is a key component connecting the push-pull screw and the sealing brick frame. The threaded hole design on it makes the connection more secure, helps to enhance the strength of the overall structure, and improves the stability and durability of the device in harsh working environments.

[0020] Furthermore, due to its structural characteristics, the L-shaped support frame usually has better load-bearing performance and can better bear the weight of components such as the sealing brick frame, sealing bricks, and push-pull screws, ensuring the stability and safety of the entire device during operation; the L-shaped support frame can also more effectively utilize the limited space around the kiln feeding port to avoid interference with other equipment or structures. The compact layout helps to reduce the equipment's footprint and improve space utilization, while also facilitating operation and maintenance by maintenance personnel.

[0021] Furthermore, installing the support frame on the steel structure of the kiln can ensure a close connection between the device and the kiln structure, thereby enhancing the stability of the entire device during operation and avoiding safety accidents caused by movement or tilting of the device.

[0022] Furthermore, compared with a single support frame, the two support frames can provide more balanced and powerful supporting force, which helps to better bear the weight of the sealing brick frame, sealing bricks, push-pull screws and other components when replacing the sealing bricks, ensuring that the entire device will not be deformed or damaged due to uneven force during operation; the two support frames are distributed on both sides of the kiln feeding port, which can form a more stable support structure, help reduce the shaking of the device caused by vibration or external force, and ensure the smooth progress of the replacement process.

[0023] Furthermore, the design of the open long hole allows the push-pull screw to have a certain adjustment space during installation, which can adapt to push-pull screws of different lengths or positions, thereby improving the versatility and flexibility of the device; through the open long hole, the operator can more easily connect the push-pull screw to the support frame without the need to precisely align each threaded hole, thereby simplifying the installation steps, reducing the installation difficulty, and improving work efficiency.

[0024] Furthermore, the rear end of the push-pull screw is installed in an open long hole, so that there is a certain lateral adjustment space during the pushing and pulling process, allowing the operator to adjust the position of the push-pull screw according to actual conditions to adapt to different installation requirements or compensate for alignment problems caused by manufacturing and installation errors.

[0025] Furthermore, the width of the open elongated hole is greater than the diameter of the push-pull screw, ensuring that the push-pull screw can move smoothly in the hole without being hindered by excessive friction, which helps to achieve smooth push-pull operations and improve the efficiency of replacing sealing bricks.

[0026] Furthermore, the flange serves as the connecting part between the screw and the support frame or other components. Its cylindrical design and larger diameter can provide a larger contact area and stronger connection strength, which helps to ensure that the push-pull screw will not loosen or fall off during the pushing and pulling process, thereby improving the stability and safety of the equipment.
