Description

Technical Field

[0001] The present invention relates to the field of plastic pipe welding processing, and particularly to a portable fluoroplastic pipe welding device. Background Art

[0002] Due to its excellent performance, fluoroplastics have been widely used in many fields. In actual engineering, in order to meet different usage requirements, it is often necessary to perform welding operations on fluoroplastic pipes.

[0003] Traditional fluoroplastic pipe welding methods mainly include hot melt welding, hot air welding, etc. During the welding process, since fluoroplastics will decompose at high temperatures, generating a series of toxic and harmful gases, such as fluorides, carbon monoxide, volatile organic compounds, etc. These waste gases have pungent odors and corrosiveness, which will not only cause harm to the respiratory tract, eyes and skin of operators, but may also cause serious health problems after long-term exposure, seriously affecting the working environment and the health of operators, and at the same time causing pollution to the atmospheric environment.

[0004] Existing waste gas treatment devices are often large in volume and complex in structure, and are not convenient to carry and move. For some situations where welding operations need to be carried out at different work sites, these devices cannot meet the actual needs. Based on this, we propose a portable fluoroplastic pipe welding device. Summary of the Invention

[0005] To solve the technical problem of waste gas purification in fluoroplastic pipe welding, the present invention provides a portable fluoroplastic pipe welding device.

[0006] The present invention is implemented by the following technical solutions: A portable fluoroplastic pipe welding device includes a welding machine and a portable electric control box; the welding machine includes an upper heating module and a lower heating module. Heating surfaces are provided on the surfaces of the upper heating module and the lower heating module, and air circulation holes are opened on the surfaces of the heating surfaces;

[0007] When the start button is pressed, the device starts to work, and the heating surfaces on the surfaces of the upper heating module and the lower heating module start to heat up. The electromagnetic heads inside them are connected to the external power supply and work together to provide energy for heating. Since the heating surface is arc-shaped and fits the outer surface of the fluoroplastic pipe, uniform heating can be achieved, enabling the welding part of the fluoroplastic pipe to reach an appropriate melting temperature for subsequent welding.

[0008] A lower module connector is fixedly connected to the outside of the lower heating module, an upper module connector is fixedly connected to the outside of the upper heating module, one end of a lower connecting pipe is fixedly connected to the outside of the lower module connector, the other end of the lower connecting pipe is connected to an air inlet joint, one end of an upper connecting pipe is fixedly connected to the outside of the upper module connector, and the other end of the upper connecting pipe is connected to an air outlet joint.

[0009] The portable electronic control box includes an outer shell of the electronic control box. A touch display screen is provided on the side of the outer shell of the electronic control box, and the touch display screen is electrically connected to a control circuit board inside the portable electronic control box; the control circuit board is circuit-connected to a quick-insert control wire harness interface connected to the side of the outer shell of the electronic control box. A negative-pressure waste gas suction pipe interface and a positive-pressure cooling air pipeline interface are installed on the side of the outer shell of the electronic control box. The negative-pressure waste gas suction pipe interface is directly above the positive-pressure cooling air pipeline interface;

[0010] One end of a waste gas pipe interface tube extends outwardly from the negative-pressure waste gas suction pipe interface, and one end of an air pipeline interface tube extends outwardly from the positive-pressure cooling air pipeline interface. The other end of the waste gas pipe interface tube is communicated with an air outlet joint on the welding machine, and the other end of the negative-pressure waste gas suction pipe interface is communicated with an air inlet joint on the welding machine. A vertically distributed waste gas pump and a blowing pump are installed inside the portable electronic control box;

[0011] When the blowing pump is started, external air enters the air inlet joint through the positive-pressure cooling air pipeline interface and the air pipeline interface tube, and then sequentially passes through the lower connecting pipe and the lower module connecting head to enter the lower heating module. The air is discharged from the air flow holes on the heating surface of the lower heating module to cool the fluoroplastic pipe being heated and welded, avoiding overheating and deformation of the pipe material and ensuring the welding quality.

[0012] One end of a first connecting pipe extends inwardly from the negative-pressure waste gas suction pipe interface into the outer shell of the electronic control box, and the other end of the first connecting pipe extending out is connected to the waste gas pump. One end of a second connecting pipe extends outwardly from the waste gas pump, and the other end of the second connecting pipe is inserted into a filter purification chamber. The other side of the filter purification chamber is connected outwardly with a cover surface, and a drainage fan is covered on the cover surface. The drainage fan is installed inside the outer shell of the electronic control box. An air outlet is provided on the side wall of the outer shell of the electronic control box, and the air outlet is opposite to the drainage fan. One end of a communicating pipe extends inwardly from the positive-pressure cooling air pipeline interface into the outer shell of the electronic control box, and the other end of the communicating pipe is connected to the blowing pump.

[0013] During the welding process, the toxic and harmful waste gas generated by the decomposition of fluoroplastics enters the upper heating module from the air flow holes, and enters the negative-pressure waste gas suction pipe interface through the air outlet joint and the waste gas pipe interface tube. The waste gas pump sucks the waste gas from the negative-pressure waste gas suction pipe interface through the first connecting pipe, and then transports it to the filter purification chamber through the second connecting pipe. The activated carbon filled inside the filter purification chamber adsorbs the harmful gases in the waste gas, and the high-efficiency filter screen filters the fine particles. The purified gas is discharged from the equipment through the air outlet under the action of the drainage fan, thereby effectively reducing the harm of the waste gas to the environment and operators.

[0014] As a further optimized solution of the present invention, the welding machine further includes a start button and a two-color indicator light. The start button and the two-color indicator light are both embedded in the upper wall surface of the upper heating module; during the heating process, the two-color indicator light can display the working state of the equipment. For example, red indicates heating, and green indicates heating completion or normal standby of the equipment, etc.

The upper heating module and the lower heating module are rotated through the rotating shaft to be closed.

[0016] As a further optimized solution of the present invention, a clamping rod is fixedly installed on the outer wall of the lower heating module, and fixing bolts are fixedly connected to both ends of the clamping rod. A clamping component is arranged on the upper heating module, and the clamping component is fixed in cooperation with the clamping rod through a spring buckle; the cooperation of the clamping rod on the outer wall of the lower heating module and the clamping component on the upper heating module is used for fixing to ensure the stability of the fluorine plastic pipe.

[0017] As a further optimized solution of the present invention, the heating surfaces provided on the upper heating module and the lower heating module are both arc-shaped. The upper heating module and the lower heating module are closed to form a circular opening, and a fluorine plastic pipe is clamped inside the circular opening. The heating surfaces are arc-shaped and fit the outer surface of the fluorine plastic pipe, which can achieve uniform heating, so that the welding part of the fluorine plastic pipe reaches a suitable melting temperature for subsequent welding.

[0018] As a further optimized solution of the present invention, the air circulation holes penetrate through the heating surfaces of the upper heating module and the lower heating module, and the air circulation holes form a gas circulation channel with the air inlet joint and the air outlet joint.

[0019] As a further optimized solution of the present invention, both the air inlet joint and the air outlet joint are quick-connect interfaces, which are detachably connected to the upper connecting pipe and the lower connecting pipe respectively, and the upper connecting pipe and the lower connecting pipe are sealed through a sealing gasket.

[0020] As a further optimized solution of the present invention, the inside of the filtration and purification chamber is filled with activated carbon and a high-efficiency filter screen. The activated carbon is used to adsorb harmful gases in the waste gas, and the high-efficiency filter screen can filter fine particles in the waste gas.

[0021] As a further optimized solution of the present invention, the air flow is communicated with the air inlet joint and the lower connecting pipe through the positive pressure cooling air pipeline interface and the air pipeline interface pipe, and is connected to the lower heating module through the lower module connector. The air flow is discharged from the air circulation hole to form an air inlet channel;

[0022] As a further optimized solution of the present invention, the air outlet of the air flow is connected to the air outlet joint from the air circulation hole in the upper heating module, and is connected to the negative pressure waste gas suction pipe interface through the waste gas pipe interface pipe. The negative pressure waste gas suction pipe interface extends to the first connecting pipe, passes through the waste gas pump, and is guided into the filtration and purification chamber through the second connecting pipe. Through the drainage of the drainage fan, it is discharged through the air outlet to form an air outlet channel.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] Heating surfaces 19 are provided on the surfaces of both the upper heating module 11 and the lower heating module 12, and air circulation holes 110 are formed on the surfaces of the heating surfaces 19.

[0043] The heating surfaces 19 provided on the upper heating module 11 and the lower heating module 12 are both arc-shaped. The upper heating module 11 and the lower heating module 12 are closed to form a circular opening, and the fluorine plastic pipe 3 is clamped inside the circular opening.

[0044] In the specific technical solution, press the start button 13, and the equipment starts to work. The heating surfaces 19 on the surfaces of the upper heating module 11 and the lower heating module 12 start to generate heat. The electromagnetic heads 117 inside them are connected to the external power supply and work together to provide energy for heating. Since the heating surface 19 is arc-shaped and fits the outer surface of the fluorine plastic pipe 3, uniform heating can be achieved, enabling the welding part of the fluorine plastic pipe 3 to reach an appropriate melting temperature for subsequent welding.

[0045] In the technical solution that needs to be explained, the air circulation holes 110 penetrate through the heating surfaces 19 of the upper heating module 11 and the lower heating module 12, and the air circulation holes 110 form a gas circulation channel with the air inlet joint 115 and the air outlet joint 116.

A touch display screen 22 is provided on the side of the electric control box housing 21, and the touch display screen 22 is electrically connected to the control circuit board inside the portable electric control box 2.

[0049] The control circuit board is electrically connected to the quick-connect control wire harness interface 23 connected to the side of the electric control box housing 21. A negative pressure waste gas suction pipe interface 25 and a positive pressure cooling air pipeline interface 26 are installed on the side of the electric control box housing 21. The negative pressure waste gas suction pipe interface 25 is directly above the positive pressure cooling air pipeline interface 26.

[0050] One end of the negative pressure waste gas suction pipe interface 25 extends outward and is connected to one end of the waste gas pipe interface pipe 27. One end of the positive pressure cooling air pipeline interface 26 extends outward and is connected to one end of the air pipeline interface pipe 28.

Inside the portable electronic control box 2, there is a vertically distributed waste gas pump 29 and a blowing pump 210 installed.

[0051] For the specific technical solution, when the blowing pump 210 is started, external air enters the air inlet joint 115 through the positive pressure cooling air pipeline interface 26 and the air pipeline interface pipe 28, and then sequentially passes through the lower connecting pipe 113 and the lower module connecting head 111 to enter the lower heating module 12. The air is discharged from the air flow holes 110 on the heating surface 19 of the lower heating module 12 to cool the fluoroplastic pipe 3 being heated and welded, avoiding overheating and deformation of the pipe material and ensuring the welding quality.

[0052] The negative pressure waste gas suction pipe interface 25 extends inwardly into the interior of the electronic control box housing 1 and is connected to a first connecting pipe 251.

[0053] For a further specific implementation, during the welding process, the toxic and harmful waste gas generated by the decomposition of the fluoroplastic enters the upper heating module 11 from the air flow holes 110, and enters the negative pressure waste gas suction pipe interface 25 through the air outlet joint 116 and the waste gas pipe interface pipe 27. The waste gas pump 29 sucks the waste gas from the negative pressure waste gas suction pipe interface 25 through the first connecting pipe 251, and then transports it to the filtration and purification chamber 253 through the second connecting pipe 252. The activated carbon filled inside the filtration and purification chamber 253 adsorbs the harmful gases in the waste gas, and the high-efficiency filter screen filters the fine particles. The purified gas is discharged from the equipment through the air outlet 256 under the action of the drainage fan 255, thereby effectively reducing the harm of the waste gas to the environment and the operators.

[0054] For the preferred technical solution, the filtration and purification chamber 253 is filled with activated carbon and a high-efficiency filter screen. The activated carbon is used to adsorb the harmful gases in the waste gas, and the high-efficiency filter screen can filter the fine particles in the waste gas.

The negative pressure waste gas suction pipe interface 25 extends to the first connecting pipe 251, passes through the waste gas pump 29, and is guided into the filtration and purification chamber 253 through the second connecting pipe 252. Through the diversion of the diversion fan 255, it is discharged through the air outlet 256 to form an air outlet channel.

[0057] For the convenience of understanding this solution, the specific working process of this portable fluoroplastic pipe welding device is as follows:

[0058] Equipment preparation and pipe fixing:

[0059] During use, first place the fluoroplastic pipe 3 to be welded inside the circular opening formed by the closing of the upper heating module 11 and the lower heating module 12. Rotate the upper heating module 11 and the lower heating module 12 through the rotating shaft 15 to close them, and then use the cooperation of the clamping rod 16 on the outer wall of the lower heating module 12 and the buckle component 18 of the upper heating module 11 to fix it to ensure the stability of the fluoroplastic pipe 3.

[0060] Heating and welding process:

[0061] Press the start button 13, and the device starts to work. The heating surfaces 19 on the surfaces of the upper heating module 11 and the lower heating module 12 start to heat up. The electromagnetic heads 117 inside them are connected to the external power supply to work together to provide energy for heating. Since the heating surface 19 is arc-shaped and fits the outer surface of the fluoroplastic pipe 3, uniform heating can be achieved, so that the welding part of the fluoroplastic pipe 3 reaches an appropriate melting temperature for subsequent welding. During the heating process, the dual-color indicator light 14 can display the working state of the device. For example, red indicates heating, and green indicates that the heating is completed or the device is in normal standby, etc.

[0062] Cooling air circulation:

[0063] At the same time, the air blowing pump 210 is started. External air enters the intake joint 115 through the positive pressure cooling air duct interface 26 and the air duct interface pipe 28, and then sequentially enters the lower heating module 12 through the lower connecting pipe 113 and the lower module connector 111. The air is discharged from the air flow through hole 110 on the heating surface 19 of the lower heating module 12 to cool the fluoroplastic pipe 3 being heated and welded, avoiding overheating and deformation of the pipe and ensuring the welding quality.

[0064] Waste gas treatment process:

[0065] During the welding process, the toxic and harmful waste gas generated by the decomposition of fluoroplastics enters the upper heating module 11 through the air flow holes 110, and enters the negative pressure waste gas suction pipe interface 25 through the air outlet joint 116 and the waste gas pipe interface pipe 27. The waste gas pump 29 sucks the waste gas from the negative pressure waste gas suction pipe interface 25 through the first connecting pipe 251, and then transports it to the filtration and purification bin 253 through the second connecting pipe 252. The activated carbon filled inside the filtration and purification bin 253 adsorbs the harmful gases in the waste gas, and the high-efficiency filter screen filters the fine particles. The purified gas is discharged from the equipment through the air outlet 256 under the action of the drainage fan 255, thereby effectively reducing the harm of the waste gas to the environment and operators.
