Embodiment Construction

[0023] The embodiment of the present invention: the bottom plate 1, the protection tube 2 and their parts are made, the heat-resistant steel material is used to cast the reinforced protective layer 3 on the outside of the bottom plate 1, the protective tube 2, and the flanges and holes are processed in the reinforced protective layer 3 according to the attached Install as shown in the figure.

[0024] The specific process is as follows: first weld the bottom plate 1 and the protective tube 2 to each other to form a casing, which becomes the casing for inserting the thermocouple later; the outside of the casing is cast with heat-resistant steel castings, namely the reinforced protective layer 3, as a whole, heat-resistant cast steel The parts are resistant to high temperature and corrosion, and can protect the inserted thermocouple from corrosion; flange 4 is welded on the upper end of the casing, which is convenient to connect and fix with the flange 9 through the bolt assembly 10...

Abstract

The invention discloses a thermo element protector for the impregnating furnace. The motherboard (1) is in the bottom of the protector tube (2) which the outside is the reinforced covering layer (3) founded by the heat-resistant steel material. The flange (4) is on the top of the protector tube which is connected by the bolt units (10); also it has the rubber blanket (5) between the flanges; the outside of the connecting groove (6) is connected with the flange and the inside is connected with the connecting cap (7) by the screw thread; the junk ring (8) and the asbestos-cement filler (12) are between the underside of the connecting cap and the connecting groove; the constant hole (11) is in the protector tube; the upper end of the reinforced protecting layer has the flange and hole. The invention can prolong the life of the use in the high temperature and the corrosive liquid and ensure the temperature measuring precision.

Description

Technical field [0001] The invention relates to a thermocouple protection device. Background technique [0002] The function of the thermocouple protection device of the immersion furnace is to protect the thermocouple inserted into the liquid in the furnace for temperature measurement, so as to achieve the purpose of extending its life. [0003] The liquid used to impregnate the anode carbon block in the impregnation furnace is phosphoric acid and sodium metaphosphate, which are quite corrosive and the liquid temperature is very high. The thermocouple cannot be directly inserted into the liquid in the furnace, but inserted into the inner tube of the protection device (not with The liquid in the furnace is in direct contact), the protection device is immersed in the liquid in the furnace according to the design size, and the thermocouple temperature measurement is indirect temperature measurement; the protection device is a must for the thermocouple. Because the temperature contr...
