Abstract
The utility model relates to a double-body high-temperature terminal block for a lifting electromagnet, which is the improvement of the integral high-temperature terminal block for a lifting electromagne. The utility model utilizes a heat insulating mattress between the upper body and the lower body, hollow bolts in flanged joint, a heat insulating washer and a heat insulating casing tube to cut off the passes of heat conduction, the direct heat influence on the terminal block caused by high-temperature adsorbed substances is eliminated. The utility model enhances economical efficiency and reliability, and can be conveniently checked and repaired.
Description
The utility model is used for the high temperature lifting electromagnet, is the improvement to existing integrative-structure high temperature lifting electromagnet connection box.
The housing of existing high temperature lifting electromagnet and connection box adopt the one-step casting moulding, or the moulding welding connects respectively, all is structure as a whole.In operation process, the heat of high temperature adsorbate directly reaches connection box through electromagnet housing, and the temperature of connection box often is in more than 180 ℃.Under hot conditions, the performance of the insulating material in the connection box greatly reduces, so easily cause thermal breakdown ground connection.To the processing of high temperature lifting electromagnet connection box, often adopt resistant to elevated temperatures porcelain bushing and resistant to elevated temperatures insulating material at present.So not only make structure very complicated, and increased cost widely, also be not easy to maintenance.
The utility model is at above-mentioned shortcoming, changes the integrative-structure of existing connection box into two body structures, takes heat insulation, radiating treatment, the heat conducting path of cut-out, thereby eliminates the direct heat influence of high temperature adsorbate butted line box.
Main points of the present utility model are connection boxes of a kind of two body structures of design, the lower body of connection box (13) connects with electromagnet housing (14) welding, isolate with heat insulating mattress (20) between the lower body (13) of upper body of connection box (10) and connection box, and connect with flange.Flange attachment bolt (19) adopts hollow structure, is beneficial to heat radiation.Heat insulating washer (18) and thermal sleeve (21) have been used in hollow bolt (19) connection place, have reduced the heat affecting of connection box lower body (13) butted line box upper body (10).
The utility model can not only be applied to the high temperature lifting electromagnet to the connection box of normal temperature electromagnet, and has improved economy and reliability, also easy access.
Description of drawings:
Fig. 1 is the assembly drowing of two body structure high temperature lifting electromagnet connection boxes.1 is the watertight nut among the figure, and 2 is tightening seal washer, and 3 is plain cushion, and 4 is cable, and 5 is insulcrete, 6 is filler, and 7 is insulcrete, and 8 is connector cover, and 9 is O-ring seal, and 10 is the connection box upper body, 11 is fish paper, and 12 are the heat radiation backplate, and 13 is the connection box lower body, and 14 is electromagnet housing, and 15 is coil.
Fig. 2 is the partial view that two body structure high temperature lifting electromagnet connection box flanges connect.16 is spring chair among the figure, and 17 is plain cushion, and 18 is heat insulating washer, and 19 is hollow bolt, and 20 is heat insulating mattress, and 21 is thermal sleeve, and 22 is nut.
Heat insulating mattress in the utility model (20), heat insulating washer (18) and thermal sleeve (21) all use polytetrafluoroethylene (PTFE) to make, and be respond well.
