Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing equipment technology, and in particular to a thermocouple brick replacement device. Background Technology

[0002] Temperature control inside the glass furnace is crucial during the glass firing process, directly affecting the melt quality, forming effect, and product qualification rate. Thermocouple bricks, a special type of refractory brick integrating thermocouples, are typically embedded in the furnace wall. The internal thermocouples monitor the furnace temperature in real time and transmit the temperature signal to the control system, providing precise data for furnace temperature regulation.

[0003] In the glass production process, the traditional method for replacing thermocouple bricks is to first loosen them with a pry bar before removing them. This method is not only inefficient, but also poses serious safety hazards. If the thermocouple bricks are subjected to uneven force, they can easily break and fall into the kiln, which not only increases the labor intensity of manual retrieval, but also seriously affects the quality of the glass. It may even cause the bricks to get stuck in the flow channel, resulting in a production accident.

[0004] There is an urgent need for a thermocouple brick replacement device that can completely remove the thermocouple brick. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermocouple brick replacement device to avoid the thermocouple brick from breaking during the replacement process and reduce safety risks.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model is: a thermocouple brick replacement device, including clamping claws, two clamping claws symmetrically arranged, a connecting ring fixedly welded to one side of each clamping claw, a heat insulation rod fixedly installed inside the connecting ring, a sliding cylinder fixedly connected to one end of the heat insulation rod, and a crossbar inserted inside the sliding cylinder; the two clamping claws are connected by a fastening mechanism.

[0007] As a preferred technical solution, the fastening mechanism includes a bearing, which is symmetrically installed in a through hole on one of the clamping claws. The outer ring of the bearing is fixed in the through hole, and the inner ring of the bearing is fixedly connected with a bolt. One end of the bolt is screwed into a threaded hole at one end of the other clamping claw.

[0008] The fastening structure can also use bolts and nuts, with the bolts passing through the two clamping jaws and then connected to the nuts.

[0009] As a preferred technical solution, one end of the bolt is integrally formed with a limiting plate.

[0010] As a preferred technical solution, the inner sidewall of the clamping claw is provided with claw teeth.

[0011] As a preferred technical solution, the heat insulation rod is made of heat insulation materials such as ceramic or wood.

[0012] As a preferred technical solution, the crossbar is made of wood.

[0013] This utility model has at least the following beneficial effects: The beneficial effects of this utility model are that by setting a fastening mechanism, the clamping claws are fitted onto the end of the thermocouple brick to be replaced, ensuring that the clamping claws and the thermocouple brick are in close contact. After the thermocouple brick is loosened by rotation, the entire thermocouple brick can be disassembled, avoiding the breakage of the thermocouple brick during the replacement process. The operation is safe, and the thermocouple brick replacement operation can be carried out under the normal operation of the glass kiln, which greatly shortens the replacement time, thereby avoiding the economic losses caused by long-term production line shutdown and greatly improving production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 An embodiment of this utility model provides a thermocouple brick replacement device, including two clamping claws 1, which are arranged opposite to each other and symmetrically. A connecting ring 102 is fixedly welded to one side of the clamping claw 1, and a heat insulation rod 2 is fixedly installed inside the connecting ring 102. A slide cylinder 3 is fixedly connected to one end of the heat insulation rod 2, and a crossbar 4 is inserted into the slide cylinder 3. A fastening mechanism 5 is installed on one of the clamping claws 1.

[0020] The fastening mechanism 5 includes a bolt 501 and a bearing 502. The bearing 502 is symmetrically installed in the through hole 104 on one of the clamping claws 1, with its outer ring fixed inside the through hole 104. The bolt 501 is fixedly connected to the inner ring of the bearing 502, and one end of the bolt 501 is screwed into the threaded hole 105 at one end of the other clamping claw 1. The cooperation between the bearing 502 and the bolt 501 reduces the resistance to the rotation of the bolt 501. This is because during operation, workers have to bend down to connect the two clamping claws 1, which is physically demanding and difficult to operate. The bearing 502 allows workers to connect the two clamping claws 1 more quickly and conveniently, ensuring that the clamping claw 1 fits tightly against the end of the thermocouple brick to be replaced. This allows for thermocouple brick replacement operations to be performed while the glass furnace is running normally, significantly shortening the replacement time and avoiding economic losses caused by prolonged production line shutdowns, thus greatly improving production efficiency.

[0021] One end of the bolt 501 is integrally formed with a limiting plate 503. By setting the limiting plate 503, it can prevent the bolt 501 from slipping out of the other clamping claw 1 during the loosening and rotation process. The two clamping claws 1 are kept in a certain connection, which not only avoids loss, but also makes the operation more convenient.

[0022] Claw teeth 103 are provided on the inner side wall of the clamping claw 1. By providing claw teeth 103, the friction is increased, so that the clamping claw 1 further abuts against the end of the thermocouple brick, preventing it from falling into the kiln during movement.

[0023] The heat insulation rod 2 is made of heat-insulating materials such as ceramic or wood. It can block the heat transfer on the clamping claw 1 and prevent high temperature from being conducted to the slide cylinder 3 and crossbar 4, making it easy to operate.

[0024] The crossbar 4 is made of wood. It is lightweight and highly portable, reducing the overall weight of the device, while also being environmentally friendly, safe, and low-cost, greatly facilitating its use by staff.

[0025] The working principle of this utility model is as follows: In use, the clamping claw 1 is fitted onto the end of the thermocouple brick. Then, the bolt 501 on the fastening mechanism 5 is rotated to tighten it, ensuring that the two clamping claws 1 are stably connected to the end of the thermocouple brick. This causes the cylindrical tail of the thermocouple brick to bear the overall force. The operator inserts the crossbar 4 into the sliding cylinder 3 and slowly rotates the crossbar 4, gradually loosening the thermocouple brick. When the thermocouple brick is loosened to a certain extent, it can be completely removed. This allows for the replacement of the thermocouple brick while the glass kiln is running normally, effectively avoiding the problem of thermocouple brick breakage and falling into the kiln, reducing safety risks, significantly shortening replacement time, avoiding economic losses caused by prolonged production line shutdowns, greatly improving production efficiency, and ensuring the stability of glass quality. Simultaneously, it reduces a series of production problems and quality losses caused by thermocouple brick breakage and falling into the kiln.

[0026] In other embodiments, the fastening mechanism connecting the two gripping claws 1 can also adopt a bolt and nut structure, with the bolt passing through the two gripping claws 1 and then connecting to the nut, making the structure simpler.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
