Description
Technical Field
The utility model relates to a high-temperature electric heating element, in particular to a U-shaped silicon carbide rod.
Background
The silicon carbide rod is a rod-shaped or tubular non-metal high-temperature electric heating element which is prepared by processing high-purity green hexagonal silicon carbide serving as a main raw material according to a certain material ratio to prepare a blank, and carrying out high-temperature silicification at 2200 ℃ and recrystallization sintering. The normal use temperature in oxidizing atmosphere can reach 1450 deg.C, and the continuous use time can reach 2000 hr.
The U type is a common structure in the elema, and the hot section adopts column or bar-shaped structure, leads to the area less with the air contact like this, and the heat of inside production can't directly be transmitted to the surface, causes the heat conduction inefficiency, and the heat duration is overlength.
SUMMERY OF THE UTILITY MODEL
The utility model provides a U type elema has solved the problem of current U type elema heat conduction efficiency low, heat time overlength.
The technical scheme of the utility model is realized like this: the utility model provides a U type elema, includes single spiral pipe, single spiral pipe perpendicular connection at the tip of connector, two single spiral pipes and a connector form the U-shaped structure, single spiral pipe includes the cold section of one end, the hot section of middle part single spiral and the linkage segment of the other end, the linkage segment is connected with the connector.
The connector comprises a strip-shaped connecting rod, and the connecting section is connected with the side part of the long end of the connecting rod.
The cross section of the connecting rod is rectangular.
The long end side part of the connecting rod is provided with a positioning column, the positioning column is in hollow fit with the inside of the connecting section, and a positioning ring is formed between the connecting rod and the connecting section in a welding mode.
The positioning column is connected with the connecting plate, a reinforcing rod is arranged on the connecting plate, and the reinforcing rod is in hollow fit with the interiors of the hot section and the cold section.
The cross section of the reinforcing rod is in a cross shape.
The utility model has the advantages that: the columnar and tubular hot section with small heat exchange area is replaced by a single spiral pipe, so that the heat exchange area is increased, and the transmission of internal and external heat is enhanced; the structure of a positioning column, a reinforcing rod and the like is added, the strength of the single spiral pipe is improved, and meanwhile, the single spiral pipe is convenient to connect and install.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of the present invention.
Fig. 3 is an exploded view of the present invention.
In the figure: 1-single spiral pipe, 2-connector, 11-cold section, 12-hot section, 13-connecting section, 21-connecting rod, 22-positioning column, 23-positioning ring, 24-connecting plate and 25-reinforcing rod.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in figures 1 to 3, the U-shaped silicon carbide rod comprises a single spiral pipe 1 and a connector 2, wherein the single spiral pipe 1 is vertically connected to the end part of the connector 2, and two single spiral pipes 1 and one connector 2 form a U-shaped structure. With the hot section of traditional U type elema, by inside and outside not intercommunication, the slower tubulose of heat transfer or bar-like change interior outer spiral intercommunication, the higher single spiral pipe of heat transfer for the inside and outside thermal transmission of elema has improved the work efficiency of elema.
The single spiral pipe 1 comprises a cold section 11 at one end, a hot section 12 at the middle part of the single spiral pipe and a connecting section 13 at the other end, and the connector 2 comprises a connecting rod 21, a positioning column 22, a connecting plate 24 and a reinforcing rod 25. The two cold sections form the two cold ends of the entire silicon carbide rod. The structure of single spiral pipe increases the heat exchange area of the hot section and brings the clearance convenient for the internal and external heat exchange. The connecting section 13 is used for connection and is connected with the long end side part of the connecting rod 21, and a positioning ring 23 is formed by welding between the connecting rod 21 and the connecting section 13.
The connective bar 21 is rectangular for the cross section, and the long end lateral part of connective bar 21 is equipped with reference column 22, and reference column 22 and linkage segment 13's inside cavity cooperation, when the linkage segment is connected with the connective bar, the reference column can play the effect of location direction, and the connection operation of being convenient for can again support the linkage segment in inside after the welding is accomplished, improves the joint strength of whole silicon-carbon rod.
In addition, the positioning column 22 is connected with a connecting plate 24 in a welding mode, a reinforcing rod 25 with a cross-shaped cross section is arranged on the connecting plate 24, and the reinforcing rod 25 is in hollow fit with the interiors of the hot section 12 and the cold section 11. After the single spiral pipe is connected and is accomplished, the single spiral pipe is supported from inside to the stiffener, improves the intensity of single spiral pipe, avoids the problem that the spiral pipe splits, collides with.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
