Description

Technical Field

[0001] This utility model belongs to the technical field of alarm devices for water-sealed pools of mesh belt quenching furnaces, and provides a water-sealed liquid level alarm device for mesh belt quenching furnaces that effectively ensures the accuracy of liquid level monitoring and reduces the product scrap rate. Background Technology

[0002] In existing mesh belt quenching furnaces, water seals are primarily used to protect the surface of parts, preventing the formation of oxide scale due to oxidation within the high-temperature furnace. Simultaneously, the water seal stabilizes the surface structure of the parts, ensuring precision and performance during machining. Current water seal level alarms for mesh belt quenching furnaces typically employ float-type alarms. However, the high water temperature within the water seal tank of these furnaces makes the float valve and other components prone to scale buildup, leading to decreased alarm sensitivity or malfunction. When the alarm fails, the water seal level drops, failing to prevent air from entering the furnace. This allows air to enter, causing rapid oxidation and rendering many products unusable.

[0003] In summary, existing liquid level alarms for water seals in mesh belt quenching furnaces are prone to decreased sensitivity or failure due to scale buildup, resulting in reduced liquid level monitoring accuracy over time and a high product scrap rate. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a water-sealed liquid level alarm for a mesh belt quenching furnace that effectively ensures the accuracy of liquid level monitoring and reduces the product scrap rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a water-sealed liquid level alarm for a mesh belt quenching furnace, which includes a support frame and a lever arm rotatably connected to the top of the support frame via a pin. One end of the lever arm is fixed with a counterweight, and the other end of the lever arm is fixed with a transfer water supply tank. The bottom and / or lower part of the side wall of the transfer water supply tank are provided with a water flow hole that communicates with its inner cavity.

[0007] A horizontal support is fixed on the support frame, and a sensor is fixed at one end of the horizontal support. The sensor is electrically connected to the controller of the central control system through a wire. The controller of the central control system is electrically connected to the audible and visual alarm through a wire. The sensor is located directly below the counterweight.

[0008] To facilitate the installation of the support frame at the water seal pool of the mesh belt quenching furnace and to ensure the water level adjustment of the water supply tank to the water seal pool of the mesh belt quenching furnace from the transfer water supply tank, the above solution further includes: the support frame includes a base, a vertical support fixed to one end of the base, the lever arm being rotatably connected to the top of the vertical support via a pin, and the horizontal support being fixed on the vertical support.

[0009] To facilitate the adjustment of the relative position of the counterweight and the sensor during installation, and to ensure that the sensor can detect the position change when the counterweight falls, the above scheme further includes: the horizontal support has a strip hole, and the bolt a passing through the strip hole fixes the horizontal support to the vertical support.

[0010] To facilitate the assembly and disassembly of the support frame and the base, the above solution further includes: the lower end of the support frame is fixed to the left end of the base as a single unit by bolt b.

[0011] To facilitate securing the transfer water supply tank, the above solution further includes: a hook at the left end of the lever arm, and the transfer water supply tank is suspended at the hook by a hook or steel rope.

[0012] The beneficial effects of this invention are: the sensor is no longer located in the water-sealed pool of the quenching furnace, and scale will not be generated, affecting its monitoring accuracy. This effectively ensures the accuracy of liquid level monitoring and reduces the product scrap rate.

[0019] like Figure 1 As shown, the water-sealed liquid level alarm for the mesh belt quenching furnace of this utility model includes: a support frame 1, a lever arm 3 rotatably connected to the top of the support frame 1 via a pin 2, a counterweight 4 fixed to one end of the lever arm 3, and a transfer water supply tank 5 fixed to the other end of the lever arm 3. The bottom or / and lower part of the side wall of the transfer water supply tank 5 is provided with a water flow hole 6 communicating with its inner cavity.

[0020] A horizontal support 7 is fixed on the support frame 1. A sensor 8 is fixed at one end of the horizontal support 7. The sensor 8 is electrically connected to the controller 9 of the central control system through a wire. The controller 9 of the central control system is electrically connected to the audible and visual alarm 10 through a wire. The sensor 8 is located directly below the counterweight 4.

[0021] To facilitate the installation of the support frame 1 at the water seal pool of the mesh belt quenching furnace and to ensure the water level adjustment of the water supply tank 5 to the water seal pool of the mesh belt quenching furnace, in the above embodiment, the support frame 1 further includes a base 11, a vertical support 12 fixed to one end of the base 11, a lever arm 3 rotatably connected to the top of the vertical support 12 via a pin 2, and a horizontal support 7 fixed on the vertical support 12.

[0022] To facilitate the adjustment of the relative position of the counterweight 4 and the sensor 8 during installation, and to ensure that the sensor 8 can sense the position change when the counterweight 4 falls, in the above embodiment, the horizontal support 7 has a strip hole 13, and the bolt a14 passing through the strip hole 13 fixes the horizontal support 7 to the vertical support 12.

[0026] The usage process of the structure described in the above embodiment is as follows: First, the support frame 1 is fixed at the water seal pool of the quenching furnace. The design alarm water level line of the water seal pool is connected through a pipe, and the outlet of the pipe connected to the water seal pool is located above the inner cavity of the transfer water supply tank 5. When the water supply in the water seal pool of the quenching furnace is interrupted or the flow rate decreases, the water in the transfer water supply tank 5 at the left end of the lever arm 3 will quickly flow out along the water outlet 6 at the bottom and / or the lower side wall. According to the lever principle, the counterweight 4 at the right end of the lever arm 3 will fall. The falling counterweight 4 contacts the sensor 8, and the sensor 8 feeds back the signal of the change in the position of the counterweight 4 to the controller 9 of the central control system. The controller 9 of the central control system controls the audible and visual alarm 10 to generate an alarm, reminding the operator to take timely countermeasures. Throughout the process, the sensor 8 is no longer located in the water seal pool of the quenching furnace, and no scale will be generated that affects its monitoring accuracy, thus effectively ensuring the accuracy of liquid level monitoring and reducing the product scrap rate.
