Description

Technical Field

[0002] The furnace chamber is a sealed hollow cavity, which is the core space of the heat treatment equipment to accommodate workpieces, achieve atmosphere control and high-temperature treatment. The furnace chamber is connected to the gas filling pipe, which can introduce protective gas to replace the internal air, create a controllable atmosphere environment, and reduce the oxidation of workpieces under high-temperature conditions.

[0003] When the furnace is in use, the workpiece to be processed is placed inside the sealed furnace chamber and the furnace body is sealed. The atmosphere supply system is started, and protective gas is continuously introduced into the furnace chamber through the main gas filling pipe. The protective gas is continuously introduced into the furnace chamber, gradually driving out and replacing the air originally present in the furnace chamber, reducing the content of harmful components such as oxygen and water vapor in the furnace chamber. The gas is continuously introduced until the gas composition and pressure inside the furnace chamber reach the process specification standards, thus creating a stable protective atmosphere environment. After the atmosphere meets the standards, the heating or corresponding processing steps are started under this sealed atmosphere conditions, and the workpiece completes the heat treatment processing in an environment isolated from air oxidation.

[0004] During long-term gas filling of the furnace chamber, dust and other pollutants can easily accumulate on the inner wall of the gas filling pipe.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Specific implementation examples are given below.

[0021] like Figures 1 to 5As shown in the embodiment of the present invention, a self-cleaning device for pipelines during furnace chamber filling includes a furnace chamber body 1; a sealing door 11 is fixedly connected to the side wall of the furnace chamber body 1; a gas supply assembly 12 is provided on the side wall of the furnace chamber body 1; a first connecting pipe 13 is fixedly connected to the top end of the gas supply assembly 12; a filling pipe 14 is fixedly connected to the top end of the first connecting pipe 13; the filling pipe 14 is connected to the side wall of the furnace chamber body 1; a high-pressure pump 15 is fixedly connected to the side wall of the furnace chamber body 1; a second connecting pipe 16 is fixedly connected to the side wall of the high-pressure pump 15; a gas tank 17 is fixedly connected to the side wall of the furnace chamber body 1; the second connecting pipe 16 is connected to the gas tank 17. Side wall; a jet pipe 18 is fixedly connected to the side wall of the gas tank 17; the jet pipe 18 is connected to the side wall of the gas filling pipe 14; a first valve 19 is provided in the middle of the jet pipe 18; a second valve 110 is fixedly connected to the side wall of the furnace chamber body 1; the second valve 110 is connected to the side wall of the gas filling pipe 14; a second valve 110 is fixedly connected between the first connecting pipe 13 and the gas filling pipe 14; a waste box 111 is provided on the side wall of the gas filling pipe 14; a filter cloth 112 is fixedly connected in the middle of the waste box 111; during operation, under normal gas filling conditions in the furnace chamber, a pair of second valves 110 are opened, and then a pair of first valves 19 are closed, supplying gas to the furnace chamber. The charging gas generated by the gas assembly 12 enters the charging pipe 14 through the first connecting pipe 13, and then enters the furnace body 1 from the charging pipe 14 to provide the furnace body 1 with the gas required for the process. When the inner wall of the charging pipe 14 accumulates contaminants after long-term gas supply and needs cleaning, a pair of second valves 110 are closed to cut off the gas supply channel from the gas supply assembly 12 to the charging pipe 14. At the same time, a pair of first valves 19 are opened to open the exhaust channel between the jet pipe 18 and the waste box 111. The high-pressure pump 15 starts running, and the high-pressure gas inside the gas tank 17 is transported to the charging pipe 14 through the jet pipe 18. After the high-pressure gas enters the charging pipe 14, it flows from the charging pipe 14 into the furnace body 1. One end of the tube 14 flows rapidly towards the waste box 111 along the inside of the inflation tube 14. During the flow of high-pressure gas inside the inflation tube 14, the pollutants attached to the inner wall of the inflation tube 14 are blown away and carried forward. The airflow carrying the pollutants enters the waste box 111 from the end of the inflation tube 14. When it flows through the filter cloth 112, the pollutants are intercepted and filtered by the filter cloth 112. The clean gas is discharged from the exhaust hole on the side wall of the waste box 111, completing the automatic cleaning of the inside of the inflation tube 14. After cleaning, the first valve 19 and the high-pressure pump 15 are closed, and the second valve 110 is opened to restore the normal air supply channel of the inflation tube 14.The opening and closing of the second valve 110 controls the flow of air through the gas supply channel, allowing independent switching between the cleaning mode and the gas supply mode. The opening and closing of the first valve 19 controls the flow of clean air, enabling high-pressure cleaning gas to enter the inflation tube 14 when needed. The high-pressure pump 15, in conjunction with the gas tank 17, rapidly delivers high-pressure gas from the gas tank 17 to the inflation tube 14, providing a sufficiently powerful airflow for cleaning the inflation tube 14. During the rapid flow of high-pressure gas inside the inflation tube 14, it blows away contaminants adhering to the inner wall and into the waste box 111, cleaning the inner wall of the inflation tube 14 during the inflation gap. The filter cloth 112 filters and intercepts the airflow carrying contaminants, trapping them inside the waste box 111. Clean gas is discharged from the waste box 111, reducing the direct discharge of polluting gas from the waste box 111 and thus reducing the pollution of the surrounding air.

[0022] like Figures 2 to 3 As shown, a connecting plate 2 is fixedly connected to the side wall of the jet pipe 18 and the inflation pipe 14; an inclined pipe 21 is fixedly connected to the side wall of the connecting plate 2; the inclined pipe 21 is disposed between the inflation pipe 14 and the jet pipe 18; a connecting plate 2 is fixedly connected between the inflation pipe 14 and the waste box 111; an inclined pipe 21 is fixedly connected to the middle of the connecting plate 2; the inclined pipe 21 is disposed between the inflation pipe 14 and the waste box 111; during operation, when high-pressure gas enters the inflation pipe 14 from the jet pipe 18, it first passes through the inclined pipe 21, and the inclined pipe 21 guides the airflow from the outlet direction of the jet pipe 18 to... The direction of the inflation pipe 14 allows high-pressure gas to smoothly enter the interior of the inflation pipe 14. When the airflow carrying pollutants inside the inflation pipe 14 flows to the waste box 111, it first passes through another set of inclined pipes 21. The inclined pipes 21 guide the airflow from the direction of the inflation pipe 14 to the inlet direction of the waste box 111, so that the airflow can smoothly enter the interior of the waste box 111. The inclined transition channel is formed at the airflow turning position by the cooperation of the connecting plate 2 and the inclined pipe 21, which reduces the impact force loss caused by the airflow hitting the wall of the inflation pipe 14 at the right angle turn, and makes the flow of high-pressure gas smoother during the cleaning process.

[0023] like Figure 3 As shown, a support plate 3 is fixedly connected to the side wall of the furnace chamber body 1; a pair of support frames 31 are fixedly connected to the side wall of the support plate 3; a fixing ring 32 is fixedly connected to the top of the support frame 31; during operation, the gas filling pipe 14 is subjected to the impact force of the airflow when high-pressure gas passes through, and the fixing ring 32 fixes the gas filling pipe 14 to the top of the support frame 31, thus supporting the gas filling pipe 14; through the cooperation of the support frame 31 and the fixing ring 32, the gas filling pipe 14 is supported and fixed at multiple points, reducing the shaking of the gas filling pipe 14 caused by the airflow impact when high-pressure gas is introduced into the gas tank 17, and reducing the risk of sealing failure of the gas filling pipe 14 and the connection due to shaking.

[0024] like Figure 5As shown, a filter box 4 is fixedly connected to the side wall of the furnace chamber body 1; the high-pressure pump 15 is connected to the side wall of the filter box 4; a filter cylinder 41 is fixedly connected to the side wall of the filter box 4; an air inlet 42 is fixedly connected to the middle of the filter box 4; during operation, when the high-pressure pump 15 runs and draws gas, the external gas enters the interior of the filter box 4 through the air inlet 42, and when it flows through the filter cylinder 41, large particulate impurities are intercepted by the filter cylinder 41, and the filtered gas enters the high-pressure pump 15 through the filter box 4; a filter structure is formed at the air inlet of the high-pressure pump 15 through the air inlet 42, reducing the entry of large particulate impurities carried in the external gas into the high-pressure pump 15 and the gas tank 17, which would cause the second connecting pipe 16 to become blocked.

[0025] like Figure 6 As shown, a protective frame 5 is fixed to the side wall of the furnace chamber body 1; a gas tank 17 is fixed to the middle of the protective frame 5; multiple sets of shielding plates 51 are fixed to the side wall of the protective frame 5; during operation, the protective frame 5 surrounds the outside of the gas tank 17, and the shielding plates 51 cover the top of the protective frame 5, isolating the gas tank 17 from the external environment; the cooperation of the protective frame 5 and the shielding plates 51 protects the gas tank 17 and reduces the impact on the gas tank 17 during use.

[0026] like Figure 5 As shown, a pair of fixing rings 6 are fixed to the inner wall of the filter box 4; an air inlet 42 is fixed to the middle of the fixing ring 6; a fixing bolt 61 is threaded to the side wall of the fixing ring 6; during operation, when a large amount of impurities accumulated on the surface of the filter cartridge 41 need to be cleaned, the top of the filter box 4 is opened, the fixing bolt 61 is unscrewed from the side wall of the fixing ring 6, the air inlet 42 is removed from the fixing ring 6, the filter cartridge 41 is cleaned or replaced, and after cleaning, the air inlet 42 is reinstalled on the fixing ring 6 and the fixing bolt 61 is tightened to fix it; the cooperation between the fixing ring 6 and the fixing bolt 61 enables the air inlet 42 to be detachably installed inside the filter box 4, which facilitates the periodic cleaning and replacement of the filter cartridge 41, reduces the problem of increased air intake resistance caused by the blockage of the filter cartridge 41, and ensures smooth air intake of the high-pressure pump 15.

[0027] like Figure 4 As shown, a damping ring 7 is fixedly connected to the middle of the fixed ring 32; the damping ring 7 is disposed between the gas filling pipe 14 and the fixed ring 32; during operation, the vibration generated by the gas filling pipe 14 when high-pressure gas passes through is transmitted to the contact position between the fixed ring 32 and the gas filling pipe 14, and the damping ring 7 is located between the gas filling pipe 14 and the fixed ring 32 to absorb and attenuate the vibration energy; the damping ring 7 forms an elastic buffer layer between the gas filling pipe 14 and the fixed ring 32, reducing the impact of the vibration of the gas filling pipe 14 transmitted to the support plate 3 and the side wall of the furnace body 1.

[0028] like Figure 6As shown, an inspection door 8 is fixedly connected to the side wall of the protective frame 5; a pair of hinges 81 are fixedly connected to the side wall of the inspection door 8; the hinges 81 are connected to the side wall of the protective frame 5; during operation, when it is necessary to inspect and maintain the gas tank 17, the inspection door 8 is opened, and the gas tank 17 is inspected and maintained inside the protective frame 5 through the opening of the inspection door 8. After maintenance is completed, the inspection door 8 is closed; the cooperation of the inspection door 8 and the hinges 81 forms an inspection channel on the side wall of the protective frame 5, which facilitates the regular inspection and maintenance of the gas tank 17 and reduces the failure of the gas tank 17.

[0029] Working principle: Under normal gas filling conditions, a pair of second valves 110 are opened, and then a pair of first valves 19 are closed. The filling gas generated by the gas supply component 12 enters the filling pipe 14 through the first connecting pipe 13, and then enters the furnace body 1 from the filling pipe 14 to provide the furnace body 1 with the gas required for the process. When the inner wall of the filling pipe 14 accumulates contaminants after long-term gas supply and needs cleaning, the pair of second valves 110 are closed to cut off the gas supply channel from the gas supply component 12 to the filling pipe 14. At the same time, the pair of first valves 19 are opened to open the exhaust channel between the jet pipe 18 and the waste box 111. The high-pressure pump 15 starts running, and the high-pressure gas inside the gas tank 17 is transported to the filling pipe 14 through the jet pipe 18. After the high-pressure gas enters the filling pipe 14, it flows out from the filling pipe 14. One end of the gas flows rapidly from the inside of the inflation tube 14 towards the waste box 111. During the flow of high-pressure gas inside the inflation tube 14, it blows away the contaminants adhering to the inner wall of the inflation tube 14, and the tube wall moves forward with the contaminants. The airflow carrying the contaminants enters the waste box 111 from the end of the inflation tube 14. When it flows through the filter cloth 112, the contaminants are intercepted and filtered by the filter cloth 112. The clean gas is discharged from the exhaust hole on the side wall of the waste box 111, completing the automatic cleaning of the inside of the inflation tube 14. After cleaning, the first valve 19 and the high-pressure pump 15 are closed, and the second valve 110 is opened to restore the normal air supply channel of the inflation tube 14. When the high-pressure gas enters the inside of the inflation tube 14 from the jet pipe 18, it first passes through the inclined pipe 21. The inclined pipe 21 directs the airflow from the outlet of the jet pipe 18. The direction is guided to the inflation pipe 14, allowing high-pressure gas to smoothly enter the inflation pipe 14. When the airflow carrying pollutants inside the inflation pipe 14 flows to the waste box 111, it first passes through another set of inclined pipes 21. The inclined pipes 21 guide the airflow from the direction of the inflation pipe 14 to the inlet direction of the waste box 111, allowing the airflow to smoothly enter the waste box 111. The inflation pipe 14 is subjected to the impact force of the airflow when the high-pressure gas passes through. The fixing ring 32 fixes the inflation pipe 14 to the top of the support frame 31, providing support for the inflation pipe 14. When the high-pressure pump 15 operates to extract gas, the external gas enters the filter box 4 through the air inlet 42. When it flows through the filter cylinder 41, large particles of impurities are intercepted by the filter cylinder 41. The filtered gas enters the high-pressure pump 15 through the filter box 4. Protective frame 5 The shield 51, installed around the outside of the gas tank 17, covers the top of the protective frame 5, isolating the gas tank 17 from the external environment. When a large amount of impurities accumulated on the surface of the filter cartridge 41 require cleaning, the top of the filter box 4 is opened, the fixing bolt 61 is unscrewed from the side wall of the fixing ring 6, and the air inlet 42 is removed from the fixing ring 6. The filter cartridge 41 is then cleaned or replaced. After cleaning, the air inlet 42 is reinstalled on the fixing ring 6, and the fixing bolt 61 is tightened. The vibration generated by the high-pressure gas passing through the inflation pipe 14 is transmitted to the contact position between the fixing ring 32 and the inflation pipe 14. The shock-absorbing ring 7 is located between the inflation pipe 14 and the fixing ring 32 to absorb and attenuate the vibration energy. When the gas tank 17 needs to be inspected and maintained, the inspection door 8 is opened.Access the protective frame 5 through the opening in inspection door 8 to inspect and maintain gas tank 17. After maintenance, close inspection door 8.
