Abstract
The utility model discloses a connecting structure between heating flat bars in a plate-type falling-film evaporator which can provide a high stability of welding and can ensure the whole flat bar parallelism well. Two heating flat bars are mutually welded via a cylindrical welding nail. A central axis of the cylindrical welding nail is vertical to the heating flat bars. The utility model is suitable for the plate-type falling-film evaporator.
Description
Technical field
The utility model relates to the syndeton between heating plates in the plate-type down-film evaporator.
Background technology
At present, heater in the plate-type down-film evaporator adopts flat heater more, connect by cylindrical weldering nail between two heating plates of this kind heater, and the central axis of weldering nail 1 is parallel with heating plates 2, its structure is referring to Fig. 1, it is line and the contacting of face that the quality problems of the heater of this structure show between weldering nail and two heating plates, cause the fusion area of weldering nail and the welding of two heating plates not enough, the quality instability of fusion, intensity is low, plate is short service life, and is easy to generate heating plates dry blowing phenomenon.
The utility model content
Technical problem to be solved in the utility model is: the syndeton between heating plates in the plate-type down-film evaporator of the whole plate depth of parallelism of a kind of welding stability height, fine assurance will be provided.
For addressing the above problem, the technical solution adopted in the utility model is: the syndeton in a kind of plate-type down-film evaporator between heating plates, and two heating plates are welded to each other by cylindrical weldering nail, and the central axis of cylindrical weldering nail is vertical mutually with heating plates.
The two ends of described weldering nail are respectively arranged with the boss through chamfering.
The beneficial effects of the utility model are: the welding stability height, guarantee the depth of parallelism of whole plate simultaneously, and guarantee the even cloth film of evaporimeter, effectively avoid the plate dry blowing.

Among the figure: 1, weldering nail, 2, heating plates, 3, the nail body, 4, convex platform, 5, lower convex platform, 6, go up heating plates, 7, heating plates down, 8, go up welding electrode, 9, lower welding pole.
The specific embodiment
Below in conjunction with accompanying drawing, the syndeton between heating plates in the utility model plate-type down-film evaporator is described in further detail.
As shown in Figure 2, the syndeton in a kind of plate-type down-film evaporator between heating plates is welded to each other by cylindrical weldering nail between last heating plates 6 and the following heating plates 7, and the central axis of cylindrical weldering nail is vertical with following heating plates 7 with last heating plates 6 respectively.Described weldering nail comprises cylinder staple body 3, and the two ends of described nail body are respectively arranged with boss---convex platform 4 and lower convex platform 5---as shown in Figure 4.Convex platform 4 and lower convex platform 5 are carried out rounding or the bevelling is handled, can reduce stress and concentrate, increase self intensity of nail body 3.
The manufacturing process of the syndeton in the utility model plate-type down-film evaporator between heating plates is: as shown in Figure 3, some weldering nails are placed between heating plates 6 and the following heating plates 7, the central axis of nail body 3 is vertical with heating plates 6, be that convex platform 4 contacts with last heating plates 6, lower convex platform 5 contacts with following heating plates 7, the opposite side of last heating plates 6 contacts with last welding electrode 8, the opposite side of following heating plates 7 contacts with lower welding pole 9, and last welding electrode 8, lower welding pole 9 is positioned on the extended line of the central axis of following closely body 3, then to last welding electrode 8 and lower welding pole 9 energisings, last welding electrode 8 and lower welding pole 9 heat last heating plates 6 and following heating plates 7 respectively, convex platform 4 and lower convex platform 5 also are heated simultaneously, after convex platform 4 and lower convex platform 5 dissolve just fully with last heating plates 6 and following heating plates 7 firm welding, be that convex platform 4 and lower convex platform 5 disappear, last heating plates 6 and following heating plates 7 respectively with follow closely body 3 on, lower surface closely contacts, just form the syndeton between heating plates in the utility model plate-type down-film evaporator, guaranteed the depth of parallelism of whole heating plates, guarantee even cloth film, effectively avoid the plate dry blowing.
Claims (2)
1. the syndeton between heating plates in the plate-type down-film evaporator, two heating plates are welded to each other by cylindrical weldering nail, it is characterized in that: the central axis of cylindrical weldering nail is vertical mutually with heating plates.
2. heating plate is followed closely with weldering in the evaporimeter according to claim 1, it is characterized in that: the two ends of described weldering nail are respectively arranged with the boss through chamfering.
