Abstract
The utility model relates to a heating device, in particular to an anti-explosion electric heater. The anti-explosion electric heater comprises a container shell, an anti-explosion chamber, transition sleeve tube bundles and electric heating tube bundles, a flange tube plate is connected with a flange of the container shell, the electric heating tube bundles are fixed on the flange tube plate and arranged in the anti-explosion chamber, a temperature-sensing probe tube is arranged in the container shell, the inner end of the temperature-sensing probe tube is arranged in the container shell, and the outer end of the temperature-sensing probe tube penetrates through the flange tube plate and fixed on the same. By the arrangement, a temperature-sensing element directly extends into the container shell from the position, and accordingly mounting is facilitated; the temperature-sensing probe tube is short, so that materials are saved; and the anti-explosion electric heater has the greatest advantages that the temperature-sensing probe tube does not need to penetrate out of the anti-explosion chamber, and accordingly tightness of the anti-explosion chamber is guaranteed, welding is simple, welding procedures are decreased, and production efficiency is improved correspondingly.
Description
Technical field
The utility model relates to a kind of heater, particularly a kind of anti-explosion electric heater.
Background technology
Existing anti-explosion electric heater comprises container casing, explosion-proof chamber, some electric heating tubes, some transition spool piece, described container casing is provided with import and export, described transition spool piece is arranged between described explosion-proof chamber and the described container casing, described transition spool piece is fixedly connected on respectively on the flange tube sheet near an end of container casing, described flange tube sheet is connected with the flange of described container casing, described each electric heating tube is fixed on the described flange tube sheet, and it is indoor to explosion-proof chamber that the terminals of described each electric heating tube pass respectively transition spool piece; Be provided with a temperature-sensing probe pipe between described each transition spool piece, an end of described temperature-sensing probe pipe passes the flange tube sheet and extends in the container casing, and the other end of described temperature-sensing probe pipe passes explosion-proof chamber and is fixed on the top of described explosion-proof chamber; The setting of this temperature-sensing probe pipe, it is fixing more loaded down with trivial details, and in order to guarantee the seal of explosion-proof chamber, the welding requirements of its junction is higher; The temperature-sensing probe pipe is longer, and consumptive material is many, and is inconvenient when placing temperature-sensing element.
Summary of the invention
The utility model provides a kind of anti-explosion electric heater, and purpose is to overcome on the existing anti-explosion electric heater that the temperature-sensing probe pipe is fixing more loaded down with trivial details, difficult, and consumptive material is many, and temperature-sensing element is installed inconvenient defective.
The utility model comprises container casing, explosion-proof chamber, the spacer shell tube bank, the electrical heating tube bank, end in described spacer shell tube bank is fixedly connected with the flange tube sheet, the other end of described spacer shell tube bank is fixed on an end of described explosion-proof chamber, described flange tube sheet is connected with described container casing flange, described electrical heating tube bank is fixed on the described flange tube sheet, it is indoor that described electrical heating tube bank is arranged on described explosion-proof chamber, a temperature-sensing probe pipe is set in described container casing, the inner of described temperature-sensing probe pipe is arranged in the described container casing, and the outer end of described temperature-sensing probe pipe is passed the flange tube sheet and is fixed on the described flange tube sheet.
The utility model is set to the outer end entrance point of temperature-sensing probe pipe on the flange tube sheet, and temperature-sensing element directly extend in the container casing from here, installs easily; The length of this temperature-sensing probe pipe only is original 2/3rds, has saved a part of material; The advantage of this set maximum is: the temperature-sensing probe pipe need not to pass from explosion-proof chamber is indoor, has guaranteed the sealing of explosion-proof chamber, and welding is simple, and welding sequence reduces, the corresponding raising of production efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1, container casing, 2, explosion-proof chamber, 3, the spacer shell tube bank, 4, the electrical heating tube bank, 5, the flange tube sheet, 6, the temperature-sensing probe pipe.
The specific embodiment
As shown in Figure 1, this anti-explosion electric heater comprises container casing 1, explosion-proof chamber 2, spacer shell tube bank 3, electrical heating tube bank 4, end in spacer shell tube bank 3 is fixedly connected with flange tube sheet 5, the other end of spacer shell tube bank 6 is fixed on an end of explosion-proof chamber 2, flange tube sheet 5 is connected with container casing 1 flange, electrical heating tube bank 4 is fixed on the flange tube sheet 5, electrical heating tube bank 4 is arranged in the explosion-proof chamber 2, a temperature-sensing probe pipe 6 is set in that container casing 1 is interior, the inner of temperature-sensing probe pipe 6 is arranged in the container casing 1, and the outer end of temperature-sensing probe pipe 6 is passed flange tube sheet 5 and is fixed on the flange tube sheet 5.
