Description

Technical Field

[0001] This application relates to the field of air intake technology for quenching furnaces, and in particular to air intake devices for quenching furnaces. Background Technology

[0002] Quenching furnaces are non-standard electric furnaces specially designed according to user requirements. They are mainly used for heat treatment such as quenching and heating of various workpieces in the aluminum industry. After the quenching furnace is evacuated, nitrogen gas needs to be filled into it.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] First, existing air intake devices usually only have an air intake on one side of the quenching furnace, which makes it difficult for nitrogen to enter the quenching furnace evenly. This results in different temperatures at different locations inside the quenching furnace, which may lead to poor quenching effect on the workpiece.

[0005] Secondly, some air intake devices are usually fixed with bolts to the air intake holes, which makes it cumbersome to disassemble and reassemble during maintenance or replacement, thus increasing the replacement time and indirectly reducing the working efficiency of the quenching furnace.

[0006] To address the aforementioned problems, the inventors proposed an air intake device for quenching furnaces to solve these issues. Utility Model Content

[0007] In order to improve the problems of uneven air intake and troublesome replacement of the device, the purpose of this utility model is to provide an air intake device for quenching furnace.

[0008] To solve the above problems, this utility model provides the following solution: an air inlet device for a quenching furnace, including a mounting ring. Multiple fixing components are provided on the outer surface of the mounting ring. An air inlet component is provided on one side of each fixing component. The air inlet component includes a vertical plate. A compression chamber is fixedly installed on one side of the vertical plate. An air inlet is opened on one side of the compression chamber. An air inlet pipe is connected inside the air inlet. An air outlet is opened on the other side of the compression chamber. The air inlet and the air outlet are connected. An air outlet pipe is connected to one side of the air outlet, and an air nozzle is connected to the end of the air outlet pipe.

[0009] Preferably, the fixing component includes a threaded rod, which is rotatably installed inside the mounting ring. An upper clamping plate is threaded onto the outer surface of the threaded rod, and the upper clamping plate is slidably installed inside the mounting ring. A lower clamping plate that cooperates with the upper clamping plate is fixedly installed on the lower inner wall of the mounting ring. A slot is provided on the opposite side of the upper and lower clamping plates, and the slot engages with the air outlet pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting up an air intake component and distributing the air intake component in a ring array on the outer surface of the mounting ring, the air intake can be made more uniform, and the gas can be compressed through the compression chamber, making the gas flow rate faster, thereby improving the practicality of the mechanism.

[0012] 2. This utility model, by setting a fixing component, uses the slots opened on the upper and lower clamps to cooperate with the clamp on the air inlet, which can fix the air inlet pipe and improve the efficiency of maintenance or replacement of a single air inlet pipe.

[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] Example: Figure 1-3As shown, this utility model provides an air intake device for a quenching furnace, including a mounting ring 1. The mounting ring 1 can be installed on the outer wall of the quenching furnace by multiple bolts on its outer surface. Multiple fixing components 2 are provided on the outer surface of the mounting ring 1. The fixing components 2 can fix the air intake component 3. The multiple fixing components 2 are arranged in a ring array, so that the fixing components 2 and the air intake component 3 are evenly distributed on the outer surface of the mounting ring 1, making the air intake more uniform. The air intake component 3 is provided on one side of the fixing component 2, and the fixing component 2 can fix the air intake component 3.

[0020] The air intake assembly 3 includes a vertical plate 36, which serves as a support. The vertical plate 36 contacts the outer surface of the mounting ring 1, allowing the vertical plate 36 to contact the mounting ring 1. A compression chamber 33 is fixedly installed on one side of the vertical plate 36, which can compress gas. An air inlet 37 is provided on one side of the compression chamber 33, allowing gas to enter its interior. An air intake pipe 34 is connected inside the air inlet 37, and an air pump can be connected to the air intake pipe 34, allowing the air pump to drive gas into the air inlet 37. An outlet 32 ​​is provided on the other side of the compression chamber 33, which can discharge gas. An inlet 37 is connected to the outlet 32, allowing gas to enter the quenching furnace through the inlet 37. The inner diameter of the inlet 37 is larger than that of the outlet 32, so that the gas will be compressed when it passes through. An outlet pipe 35 is connected to one side of the outlet 32, which can discharge gas. An air nozzle 31 is connected to the end of the outlet pipe 35, which is inserted into the quenching furnace, so that the air nozzle 31 can send gas into the quenching furnace.

[0021] The fixing component 2 includes a threaded rod 25, with a handwheel 21 fixedly mounted at its end. The handwheel 21 facilitates rotation of the threaded rod 25. The handwheel 21 is rotatably mounted on the upper surface of the mounting ring 1, allowing it to rotate in the upper half of the mounting ring 1. The threaded rod 25 is rotatably mounted inside the mounting ring 1, allowing it to rotate in the upper half of the mounting ring 1. An upper clamping plate 23 is threaded onto the outer surface of the threaded rod 25, which clamps and fixes the air outlet pipe 35. A sliding groove 22 is provided inside the mounting ring 1, allowing the upper clamping plate 23 to slide within it. The upper clamping plate 23 is slidably mounted inside the sliding groove 22, preventing it from deviating. The upper clamping plate 23 is slidably installed inside the mounting ring 1, allowing the upper clamping plate 23 to move within the mounting ring 1. A lower clamping plate 24, which works in conjunction with the upper clamping plate 23, is fixedly installed on the lower inner wall of the mounting ring 1. The upper clamping plate 23 and the lower clamping plate 24 cooperate with each other to clamp the air outlet pipe 35. A slot 26 is provided on the opposite side of the upper clamping plate 23 and the lower clamping plate 24. The slot 26 engages with the air outlet pipe 35, allowing the air outlet pipe 35 to be clamped. A clamping plate 27 is fixedly fitted on the outer surface of the air outlet pipe 35, allowing the clamping plate 27 to engage with the slot 26. The clamping plate 27 and the slot 26 work together to lock the clamping plate 27 in place, thereby fixing the air intake assembly 3.

[0022] Working principle: First, install the mounting ring 1 on the outside of the quenching furnace and connect the air nozzle 31 to the inside of the quenching furnace. At the same time, connect the end of the air inlet pipe 34 to an external air pump to deliver nitrogen into the quenching furnace. When the nitrogen enters the compression chamber 33 through the air inlet 37, it will be compressed, causing the flow rate to increase. It will be discharged from the air outlet 32 ​​and enter the quenching furnace through the air outlet pipe 35 and the air nozzle 31.

[0023] When the intake assembly 3 needs to be replaced, the corresponding fixing component 2 can be used. By turning the handwheel 21, the handwheel 21 drives the threaded rod 25 to rotate. The threaded rod 25 can drive the upper clamping plate 23 to move inside the slide groove 22 and separate from the lower clamping plate 24. This allows the clamping plate 27 to drive the exhaust pipe 35 to separate from the slot 26, thus allowing the intake assembly 3 to be replaced.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
