Description

Technical Field

[0001] The utility model belongs to the technical field of thermal processing, and more specifically, particularly relates to a smokeless tempering furnace. Background Art

[0002] The tempering furnace is an indispensable and important equipment in the metal heat treatment process. Early tempering furnaces may adopt a relatively simple structure and heating method, such as burning gas or heavy oil. With the advancement of technology, modern tempering furnaces have incorporated more advanced control systems to accurately control the temperature in the tempering furnace, making it suitable for the tempering treatment of different metals and more efficient in energy utilization. However, although the combustion efficiency in the tempering furnace has been improved, smoke will still be generated. Therefore, the tempering furnace will be equipped with a flue, and when the processed parts in the tempering furnace are taken out, a small amount of smoke will still float out through the opening, causing environmental pollution.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a smokeless tempering furnace is provided to achieve a more practical purpose. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a smokeless tempering furnace to solve the problem that a small amount of smoke still floats out from the opening when the processed parts in the tempering furnace are taken out, causing environmental pollution.

[0005] The purpose and effect of the smokeless tempering furnace of the utility model are achieved by the following specific technical means:

[0006] A smokeless tempering furnace comprises a furnace body, a flue is arranged on the top of the furnace body, the flue is connected to an exhaust pipe, a door frame is arranged on the open end of the furnace body, a smoke collecting hood is arranged on the top of the door frame, the top of the rear side of the smoke collecting hood is connected to the exhaust pipe through a branch pipe, an air permeable plate is arranged in the smoke collecting hood, smoking pipes are vertically distributed on both sides of the smoke collecting hood, the smoking pipes extend to the bottom of the furnace body opening, the top of the smoking pipes is communicated with the corresponding holes on the air permeable plate, and a sealing plate is slidably arranged in the door frame.

[0007] Furthermore, slide rails are provided on both sides of the door frame, the sealing plate is slidably clamped between the two slide rails, a control cavity is opened in one side of the door frame, a chain mechanism driven by a motor on the door frame is provided in the control cavity, and one of the links on the chain mechanism is connected to the sealing plate.

[0008] Furthermore, a mounting block is provided on one of the links of the chain of the chain mechanism, and the mounting block passes through the slide rail and is connected to the sealing plate by bolts.

[0009] Furthermore, a notch is provided on the rear side of the sealing plate, and the mounting block is clamped in the corresponding notch.

[0010] Furthermore, a stop beam is installed on the front side of the door frame, and the stop beam is located on the horizontal line of the top of the furnace body.

[0011] Furthermore, a plurality of air holes are distributed in an array inside the smoking pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Through the setting of the door frame, the door opening method of sliding the sealing plate up and down is different from the horizontal door opening method, which reduces the residual smoke brought out with the sealing plate. At the same time, the smoke overflows with the sealing plate and can be effectively collected by the smoke hood, reducing the outflow of smoke and making the environment cleaner.

[0014] 2. By distributing the smoke pipes on both sides of the furnace opening, the smoke seeping from both sides can be absorbed when the door is removed from the sealing plate, thus achieving a smoke-free effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a smokeless tempering furnace, comprising a furnace body 1, a flue 4 is arranged on the top of the furnace body 1, the flue 4 is connected to an exhaust pipe 5, a metal piece to be tempered is placed in the furnace body 1, the tempering is performed by controlling the heating temperature, and the smoke enters the exhaust pipe 5 through the flue 4;

[0027] A door frame 2 is provided at the open end of the furnace body 1, and a smoke collecting hood 6 is provided on the top of the door frame 2. The top of the rear side of the smoke collecting hood 6 is connected to the exhaust pipe 5 through a branch pipe 51. The smoke seeping out of the opening of the furnace body 1 is collected by the upper smoke collecting hood 6 and sent into the exhaust pipe 5 through the branch pipe 51. A sealing plate 3 is slidingly provided in the door frame 2. The sealing plate 3 slides up and down with the door frame 2. Compared with the horizontal door opening method, the residual smoke is reduced by the sealing plate 3. At the same time, the smoke overflows upward with the sealing plate 3 and can be effectively collected by the smoke collecting hood 6, reducing the smoke outflow and making the environment cleaner.

[0028] like Figure 3As shown, a ventilation plate 13 is arranged in the smoke collecting hood 6, and smoking pipes 61 are vertically distributed on both sides of the smoke collecting hood 6. The smoking pipes 61 extend to the bottom of the opening of the furnace body 1, and the top of the smoking pipes 61 is connected with the corresponding holes on the ventilation plate 13. The smoke collected on the top of the smoke collecting hood 6 is sucked into the branch pipe 51 through the multiple holes on the ventilation plate 13, and then enters the exhaust pipe 5. Through the arrangement of the smoking pipes 61 distributed on both sides of the opening of the furnace body, a plurality of air holes 62 are distributed in an array on the inner side of the smoking pipe 61. When the door on the sealing plate 3 is removed, the smoke seeping from both sides can be absorbed to achieve a smoke-free effect.

[0029] Among them, slide rails 12 are arranged on both sides of the door frame 2, and the sealing plate 3 is slidably clamped between the two slide rails 12. A control chamber is opened in one side of the door frame 2, and a chain mechanism driven by the motor 9 on the door frame 2 is arranged in the control chamber. One of the chain links on the chain mechanism is connected to the sealing plate 3, such as Figure 4 As shown, the motor 9 drives the chain 8 to operate, and a mounting block 10 is provided on one of the links of the chain 8 through the chain mechanism. The mounting block 10 passes through the slide rail 12 and is connected to the sealing plate 3 by bolts, so as to drive the sealing plate 3 to move up and down. In this embodiment, the rail 12 is a slide groove with an inner cavity, and the two sides of the sealing plate 3 can just be stuck in the slide groove, and the sealing plate 3 and the mounting block 10 are detachable. Figure 2 As shown, a notch 11 is provided at the rear side of the sealing plate 3 , and the mounting block 10 is clamped in the corresponding notch 11 . The notch 11 facilitates early positioning when connecting the sealing plate 3 and the mounting block 10 .

[0030] Among them, a stop beam 7 is installed on the front side of the door frame 2, and the stop beam 7 is located on the top horizontal line of the furnace body 1. The setting of the stop beam 7 limits the sealing plate 3, increases the stability of the movement of the sealing plate 3, and avoids the sealing plate 3 and the mounting block 10 from loosening and tilting.
