Description

Technical Field

[0001] The utility model relates to the technical field of piston pin manufacturing, in particular to an exhaust gas ignition device for a piston pin carburizing furnace. Background Art

[0002] A carburizing furnace is a tool that heats and keeps the workpiece warm for a long time to allow carbon to penetrate the surface of the workpiece. A layer of carbon will adhere to the surface of the workpiece after being treated in the carburizing furnace, giving the workpiece higher hardness and wear resistance.

[0003] The incinerator of the existing carburizing furnace will produce a lot of carbon-containing exhaust gas during heating. This exhaust gas is usually discharged directly into the air without being treated, which will cause great environmental pollution and is relatively wasteful. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a piston pin carburizing furnace tail gas ignition device that can achieve carburizing furnace tail gas treatment and recycling.

[0005] The utility model is realized by the following method: a piston pin carburizing furnace tail gas ignition device comprises a carburizing furnace body, a combustion chamber is arranged on the right side of the carburizing furnace body, the right side of the carburizing furnace body is connected to the combustion chamber via an air outlet pipe, a plurality of flamethrowers are embedded at equal distances on the bottom surface of the combustion chamber, and a circulating preheating part is arranged in the carburizing furnace body.

[0006] Furthermore, the circulating preheating part includes a circulating pipe, the circulating pipe is arranged inside the wall of the carburizing furnace body, the exhaust pipe is arranged on the upper surface of the combustion chamber, the air intake pipe is arranged on the upper surface of the carburizing furnace body, the air intake pipe is connected to the circulating pipe, the exhaust pipe is connected to the air intake pipe, and the circulating pipe is connected to an exhaust pump.

[0007] The beneficial effects of the present invention are as follows: a combustion chamber, a flamethrower and a circulating preheating component are added to the device; the combustion chamber is used to collect the remaining tail gas from the combustion of the carburizing furnace body, burn the carbon particles contained in the tail gas, and after combustion, the gas well circulating preheating component is transmitted back to the carburizing furnace body to achieve the preheating effect of the carburizing furnace body for next use, thereby effectively treating the tail gas; the present invention has a simple structure and is easy to operate, can effectively save manpower and material resources, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] See also Figure 1 As shown, the present invention provides an embodiment: a piston pin carburizing furnace exhaust gas ignition device, comprising a carburizing furnace body 1, a combustion chamber 2 disposed on the right side of the carburizing furnace body 1, the right side of the carburizing furnace body 1 being connected to the combustion chamber 2 via an exhaust pipe 3, a plurality of flamethrowers 4 being embedded in the bottom surface of the combustion chamber 2 at equal intervals, and a circulating preheating element 5 disposed within the carburizing furnace body 1. The exhaust gas discharged from the carburizing furnace body 1 is transported into the combustion chamber 2 via the exhaust pipe 3, where the flamethrowers 4 combust the carbon particles contained in the exhaust gas. After combustion, the gas is then transported back to the carburizing furnace body through the circulating preheating element 5, thereby preheating the carburizing furnace body for the next use.

[0011] Please continue reading Figure 1 As shown, in one embodiment of the present invention, the circulating preheating member 5 includes a circulating pipe 51, which is provided in the wall of the carburizing furnace body 1, an exhaust pipe 52 is provided on the upper surface of the combustion chamber 2, and an air intake pipe 53 is provided on the upper surface of the carburizing furnace body 1. The air intake pipe 53 is connected to the circulating pipe 51, and the exhaust pipe 52 is connected to the air intake pipe 53. The circulating pipe 51 is connected to an air extraction pump 54. The processed hot gas is discharged through the exhaust pipe 52, and is transported to the circulating pipe 51 through the air intake pipe 53 to perform a preheating operation on the carburizing furnace body 1, and then is extracted by the air extraction pump 54.

[0012] The flame spray gun, the vacuum pump and the carburizing furnace body in the present invention are all prior arts, and those skilled in the art can clearly understand them, so they will not be described in detail here.

[0013] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
