Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a flame-retardant ventilation device for a glass kiln. Background Art

[0002] A kiln or furnace is a furnace used to fire ceramics and sculptures, or to fuse enamel to metal surfaces. Typically constructed of brick and stone, it can be manufactured in various sizes and sizes, and can be powered by gas, oil, or electricity. Glass kilns, on the other hand, are used to produce glass and require flame-retardant ventilation.

[0003] Publication number CN221505672U discloses a ceramic kiln ventilation structure, including a ventilation duct, an air inlet hood is plugged into the front side of the ventilation duct, and a ventilation pipe is movably installed on the rear side of the ventilation duct, a fixing mechanism is provided on the outside of the ventilation pipe, and a mounting frame is fixedly installed on the inner cavity of the ventilation pipe, a fan is installed on the mounting frame, and a number of heating rods are installed in the inner cavity of the ventilation duct. Although this ventilation structure uses multiple heating rods arranged inside the ventilation duct to preheat the airflow, so that the airflow is heated, the heated airflow enters the interior of the ceramic kiln along the air inlet hood, reducing the energy consumption inside the furnace body. However, this ventilation structure has a fixed ventilation volume. When the kiln temperature changes, excessive or insufficient ventilation may affect product quality and increase energy consumption. Therefore, improvement is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical solution: a flame-retardant ventilation device for a glass kiln, comprising a support frame, one side of the support frame is connected to an air inlet duct, the other side of the support frame is connected to a ventilation duct, an air cylinder is fixedly installed on the top surface of the ventilation duct, a piston rod is slidably connected to the inner wall of the air cylinder, a connecting plate is fixedly installed on the top end of the piston rod, a blocking plate is fixedly installed on the bottom surface of the connecting plate, and the blocking plate is slidably connected to the air inlet duct.

[0006] Preferably, the gas cylinder is filled with gas, and the support frame is made of ceramic.

[0007] Preferably, support legs are fixedly mounted on the bottom surface of the support frame, and the support legs are symmetrically distributed on the bottom surface of the support frame.

[0008] Preferably, the air inlet duct and the ventilation duct are rectangular structures.

[0009] Preferably, a heating mechanism is provided on the top surface of the ventilation duct, and the heating mechanism includes a heat-conducting rod, and the heat-conducting rod is fixedly mounted on the surface of the air cylinder. A vertical block is fixedly mounted on the top surface of the ventilation duct, and a threaded rod is provided through the surface of the vertical block, and a sleeve is fixedly mounted on one end of the threaded rod.

[0010] Preferably, a screw cap is fixedly mounted on the other end of the threaded rod, and the screw cap is a hexagonal structure.

[0011] Preferably, a thread is provided inside the vertical block, and the thread is engaged with the threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, the ventilation duct is connected to the glass kiln, and air can be introduced through the air inlet duct. At the same time, the support frame is made of ceramic, which is heat-insulating and high-temperature resistant, and can play a flame-retardant role. The gas cylinder is filled with gas. Since the gas cylinder is close to the glass kiln, when the glass kiln is heated, it can heat the gas in the gas cylinder. After the gas is heated, the pressure can be increased, thereby pushing the piston rod to move upward. The piston rod can then drive the connecting plate to move, and the connecting plate can then drive the blocking plate to move upward. At this time, the range of the air inlet channel becomes larger, so that the air intake of the air inlet channel can be dynamically adjusted according to the temperature of the glass kiln. In the utility model, the ventilation volume can be automatically adjusted according to the temperature of the kiln without manual intervention, which can more effectively control the temperature and airflow conditions inside the kiln, ensuring the stability of the production process and product quality. Since the gas cylinder is directly exposed to the high-temperature environment, the gas inside it can quickly respond to the temperature changes of the kiln, making the ventilation system react quickly and able to adjust the air intake volume in time to effectively cope with thermal changes in kiln operation. The support frame uses high-temperature resistant ceramic materials with good heat insulation and flame retardant effects, which can reduce operational risks and increase the safety of equipment, especially in high-temperature environments.

[0014] 2. In the present invention, the heat conducting rod can be heated by the glass kiln. At this time, the heat conducting plate can conduct heat to the gas cylinder, thereby heating the gas in the gas cylinder, and the staff can twist the threaded rod by twisting the cap. Since a thread is provided in the vertical block, the threaded rod can move in the vertical block, and the threaded rod can then drive the sleeve to move. At this time, the heat conducting plate can be sleeved through the sleeve, which can reduce the surface area of ​​the heat conducting rod, thereby controlling the heating temperature of the gas and then controlling the opening amplitude of the blocking plate. The present invention can accurately control the exposed amount of the surface area of ​​the heat conducting rod by manually adjusting the position of the heat conducting plate relative to the heat conducting rod, thereby finely adjusting the heating degree of the gas in the gas cylinder, which allows the operator to accurately control the temperature and ventilation volume in the kiln as needed, and optimize the production process. By manually adjusting the position of the threaded rod and the sleeve, the operator can flexibly adjust the blocking plate according to production needs or environmental changes, providing a high degree of adjustability and adaptability, and high practicality.
