Abstract
The utility model discloses an internal heat circulating fan for a heating brazing furnace, comprising a rotating shaft and impellers which are connected with a motor, wherein, the impeller has eight blades falling into two groups and arranged in two layers on the circumference of the rotating shaft evenly; the two layers of impellers are crossingly arranged on the rotating shaft. In order to obtain optimal wind pressure and wind volume, the four impellers of each layer are arranged at ninety degrees to one another, each impeller is arranged at thirty-five degrees. The utility model has perfect flow-mixing performance and can perform atmosphere convection heat transfer of the protective gas inside the heating brazing furnace compulsively to keep the uniform temperature inside the heating brazing furnace.
Description
One, technical field
The utility model relates to the parts in a kind of intermittent type gas protecting soldering furnace, specifically a kind of interior thermal circulation fan of heating soldering stove.
Two, background technique
Intermittent type gas protecting soldering furnace is a kind of equipment that each component of aluminium heater are effectively connected.Be that this characteristic of utilizing the alloy melting point of almit Al-Si to be lower than components A l metallic material fusing point is welded.Existing soldering oven adopts continous way more, and the soldering oven electric motor power of this structural type is big, is applicable to the processing of carrying out workpiece in enormous quantities.But very flexible then is difficult to meet the demands to the workpiece of different size and kind, and when changing specification of workpieces and kind, big to the adjustment difficulty of each parameter, adjustment cycle is long.High material consumption and intermittent type gas protecting soldering furnace has overcome the shortcoming of continous way soldering oven, flexibility is strong, can satisfy the workpiece processing requirement of different size and kind, and is easy to adjust to each regional brazing process variables, and the workpiece processing quality is good.
Because the quality of workpiece processing quality is mainly determined by the process parameter in the heating soldering district, thereby when operation, at first determine process parameter in the heating soldering district according to the processing request of different workpieces, determine the parameter that other are regional by the process parameter in the heating soldering district again, and bring the time that workpiece rests on respective regions of adjusting by the control transmission.In actual the use, the relative higher preheating purifying area connection of the feed end in heating soldering district with temperature, and the relatively low cooling zone of the discharge end in heating soldering district and temperature is connected, thereby be easy to generate bigger temperature difference at the two ends in heating soldering district; And the improper temperature contrast that also can cause the workpiece positive and negative of mode of heating.The soldering processing requirements is finished under the uniform atmosphere of temperature, and this has just proposed higher requirement to the heating equipment in the heating soldering district.Common blower fan can not meet the demands.
Three, summary of the invention
The purpose of this utility model provides a kind of interior thermal circulation fan of heating soldering stove, and thermal circulation fan stirring mixed flow performance is good in this, can carry out enforceable atmosphere convection heat exchange to the shielding gas in the heating soldering stove, keeps the temperature in the heating soldering stove even.
The purpose of this utility model is achieved through the following technical solutions:
A kind of interior thermal circulation fan of heating soldering stove comprises the rotating shaft and the impeller that are connected with motor, and it is characterized in that: described impeller has 8, is divided into two groups and be divided on the two-layer circumference that evenly is arranged on rotating shaft, and two-layer impeller is interlaced to be arranged in the rotating shaft.
In the utility model, for reaching best blast and air quantity, four impellers of every layer 90 degree at interval are provided with.The wind of every impeller generation can both play effect like this.
In the utility model, the angular range of every impeller is 15～35 degree.For realizing best effect, the angle of every impeller is 35 degree.
Owing to will keep enough shielding gas atmosphere in the heating soldering stove, therefore, interior thermal circulation fan should have the sealing wind chamber that can prevent that shielding gas from leaking.For making the shielding gas that sprays in the heating soldering district even, interior thermal circulation fan is an axial-flow blower.The utility model has adopted the interior thermal circulation fan of two low noises to carry out enforceable atmosphere convection heat exchange, to improve the uniformity of each point temperature, atmosphere, its temperature control deviation is reduced.
The stirring mixed flow performance that the utility model produces is good, can carry out enforceable atmosphere convection heat exchange to the shielding gas in the heating soldering stove, keeps the temperature in the heating soldering stove even.

Fig. 2 is the side view of Fig. 1;
Fig. 3 is the A-A view of Fig. 1.
Five, embodiment
A kind of interior thermal circulation fan of heating soldering stove described in the utility model, comprise the rotating shaft 1 and the impeller 2 that are connected with motor, impeller 2 has 8, is divided into two groups and be divided on the two-layer circumference that evenly is arranged on rotating shaft 1 two-layer impeller 2 interlaced being arranged in the rotating shaft 1.For reaching best blast and air quantity, four impellers 2 of every layer 90 degree at interval are provided with.The wind of every impeller generation can both play effect like this.Be similarly and realize that best effect, the angle of swing of every impeller 2 are 35 degree.The utility model is provided with two interior thermal circulation fans in the heating soldering stove, interior thermal circulation fan should have the sealing wind chamber that can prevent that shielding gas from leaking.
The parameter of interior thermal circulation fan is: operating temperature is 700 ℃, and rotating speed is 1450 rev/mins, and air quantity is 6000m
3, blast is 140Pa.
Adopt the interior thermal circulation fan of low noise described in the utility model to carry out enforceable atmosphere convection heat exchange, can improve the uniformity of each point temperature, shielding gas atmosphere in the heating soldering stove, its temperature control deviation is reduced.
