Description
Technical Field
The utility model relates to a solder flux stoving technical field, concretely relates to submerged arc welding solder flux oven.
Background
The submerged arc welding needs to use a submerged arc welding flux, the flux needs to be kept completely dry when being used, defects such as air hole undercut and the like are avoided in the welding process, and a flux oven can fully heat the submerged arc welding flux, discharge moisture and keep dry. The existing flux oven equipment can not meet the following functions:
1) after manual opening, the welding flux is always dried at a constant temperature of 350 ℃, and the functions of temperature reduction and heat preservation are not realized;
2) when the equipment has no materials or the materials are insufficient, if the flux is not added into the oven in time, the equipment is continuously heated and is dried to burn, so that the heater is damaged;
3) the temperature difference between the inside and the outside of the flux is too large: the temperature sensor is arranged in the middle of the heating rod, the heating rod in the oven is arranged at the bottom, and the temperature sensor is arranged at the right center of the oven, so that when the center of the welding flux reaches 350 ℃, the welding flux temperature at the side of the oven is only about 280 ℃, and the use standard cannot be reached. Because the submerged arc welding flux is solid granular substances, the temperature of the welding flux is high and the temperature of the outer side is low in a position close to a heating pipe in an oven, and if the temperature detection is only used for detecting the internal temperature of the welding flux, the internal temperature and the external temperature are inconsistent, and poor welding is easy to generate.
4) The temperature of the dried flux is too high, the flux with the high temperature of about 350 ℃ cannot be used immediately, and the flux needs to be placed in air for natural cooling, and the use effect is influenced because the most reasonable use temperature of the flux is 150 ℃ and the cooling time is possibly less than 150 ℃ if too long; the temperature reduction time is short and is higher than 150 ℃, skin can be burnt when workers take materials, the high-temperature welding flux can scald a submerged arc welding flux conveying rubber pipe, and water molecules in the air can be remoistened and enter the welding flux again when the temperature is naturally reduced in the air, so that the welding use effect is influenced.
Disclosure of Invention
The utility model aims at the technical shortcoming that a submerged arc welding flux oven that can use the solder flux immediately is cooled down fast after drying is provided.
In order to realize the above purpose, the utility model provides a submerged arc welding flux oven, be in including box, storage case and setting heating pipe in the box still include with axial fan that the box exhaust hole of box links to each other, stretch into the regional K type thermocouple of heating pipe in the box with install the infrared temperature sensor of box surface, the storage case through inhale the material motor with the box links to each other.
Furthermore, a discharging valve is arranged at a discharging port of the box body, and the discharging valve is connected with a discharging cylinder electromagnetic valve.
Further, a storage box feeding sensor is arranged on the storage box.
Further, a high-temperature resistant ceramic material sensor is arranged on the box body.
Compared with the prior art, the utility model has the advantages of it is following:
1. the utility model discloses submerged arc welding solder flux oven adopts K type thermocouple to detect the inside temperature of solder flux, and infrared temperature sensor detects the outside temperature of solder flux, thus keep the equilibrium of solder flux temperature;
2. adopt axial fan to force rapid cooling to the box inside for the solder flux is at the inside cooling of box, avoids contacting once more with the hydrone among the natural cooling process and influences the solder flux result of use, and through rapid cooling and the solder flux after the heat preservation completion, can drop into use immediately, need not to wait for reuse after the natural cooling, improves production efficiency.
Drawings
Fig. 1 is a schematic structural view of a submerged arc welding flux oven of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
As shown in fig. 1, the submerged arc welding flux oven comprises a box body 3, a storage box 11, a heating pipe 7 arranged in the box body 3, a high temperature resistant ceramic material sensor 1 for detecting the material level of the box body 3, an axial flow fan 13 connected with a box body exhaust hole 4 of the box body 3, a discharge valve 12 arranged at a discharge hole 8 of the box body 3, a discharge cylinder electromagnetic valve 5 connected with the discharge valve 12 and a storage box feeding sensor 10 for detecting the material level of the storage box 11, wherein the storage box 11 is connected with the box body 3 through a suction motor 9.
And a type K thermocouple 6 for detecting the area of the heating pipe 7 inside the tank 3 and an infrared temperature sensor 2 for detecting the outer surface of the tank 3. Because of the welding flux is interior outer nonconformity of solid state granular material temperature, the welding flux temperature that is close to the heating tube is high, the temperature of keeping away from the heating tube is low, for keeping the welding flux temperature balanced, increase the inside and outside temperature-detecting device of welding flux, it is regional to stretch into the heating tube directly by K type thermocouple 6, detect the inside temperature of welding flux, establish this temperature value as T1, infrared temperature sensor 2 detects the outside temperature of welding flux, establish this temperature value as T2, both temperature signal get into intelligent temperature controller and synthesize the back, accurate accuse temperature.
In the embodiment, the model of the material storage box feeding sensor 10 is RF-100-4-1-T1-300, the model of the infrared temperature sensor 2 is IR-HTR500A, and the model of the high-temperature resistant ceramic material sensor 1 is RM41AGM 0300.
A warming stage: the heating pipe 7 is electrified to heat the welding flux in the box body 3 until the temperature is raised to the primary required temperature and the temperature is set for the primary required time to fully dry the moisture in the welding flux; when the time required for one time is up, entering a cooling stage: the function of starting taking a breath, axial fan 13 opens, reduces the inside solder flux temperature of box 3 fast to the secondary required temperature after the secondary required time that keeps warm, and the stoving in-process discharge valve 12 can't open. Adopt axial fan 13 and 3 exhaust holes 14 of box to be connected, carry out the inside rapid cooling of forcing of box 3, the solder flux is at the inside cooling of box 3, avoids in the natural cooling process to contact once more with the hydrone and influences the solder flux result of use, and the solder flux after rapid cooling and heat preservation completion, can put into use immediately, need not to wait for reuse after the natural cooling, improves production efficiency. If the temperature in the box body 3 is lower than the secondary required temperature, the temperature is raised to the secondary required temperature again, the process is repeated, and if the heat preservation time reaches the secondary required time, the machine is stopped to save electric energy without using welding flux.
When the high-temperature resistant ceramic material sensor 1 detects that the welding flux in the box body 3 is insufficient or has no welding flux, starting the material sucking motor 9, and sucking the welding flux in the material storage box 11 into the box body 3 by the material sucking motor 9; meanwhile, when the material level in the box body 3 is insufficient, the power supply of the heating pipe 7 is cut off, and the heating pipe 7 is prevented from being damaged by material shortage and dry burning.
If the welding flux in the box body 3 is not completely dried, the electromagnetic valve 5 of the discharging cylinder is opened, the discharging valve 12 is opened to close the discharging port, and the welding flux which is not completely dried can not flow out from the discharging port 8.
