The technical scheme of the present embodiment effectively solves the problem that in the prior art, in the glass production process, the platinum channel thermocouple grounding causes circuit failure.

[0034] As Figure 1 , Figure 2 , Figure 4As shown, in the technical solution of this embodiment, the box structure 11 includes a first outlet 111, a second outlet 112, and a box body 113. The first outlet 111 and the second outlet 112 are both connected to the box body 113 and are located at both ends of the box body 113, respectively. The first outlet 111 and the second outlet 112 are used for the thermocouple wire and the compensating wire to pass through, respectively, to avoid short circuits caused by contact between the two.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 113 has a receiving groove 1131, and the wiring assembly 20 is connected to the receiving groove 1131. The thickness of the wiring assembly 20 is less than the depth of the receiving groove 1131. The receiving groove 1131 provides space for the wiring assembly 20 to be arranged. The wiring assembly 20 is completely located within the receiving groove 1131, which is beneficial for heat insulation of the internal wiring assembly 20, reducing the influence of external temperature fluctuations on the wiring points, and improving measurement accuracy.

[0036] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the wiring assembly 20 includes a mounting base 21, which has multiple grooves 211. Each groove 211 corresponds to a multiple wiring point, and the wiring points are located within the grooves 211. The multiple grooves 211 separate the various wiring points, preventing mutual interference between the lines.

[0037] like Figures 1 to 3 As shown, in this embodiment, multiple grooves 211 are symmetrically distributed on both sides of the mounting base 21, and are respectively configured to correspond to the first outlet 111 and the second outlet 112. Thermocouple wires pass through the first outlet and connect to the wiring points distributed in the grooves 211 on the first side of the mounting base 21, and compensating wires pass through the second outlet and connect to the wiring points distributed in the grooves 211 on the second side of the mounting base 21.

One metal sheet 23 is correspondingly provided with two threaded holes and two bolts, the compensation lead wire and the thermocouple wire are respectively wound on the corresponding two bolts 22, and the compensation lead wire and the thermocouple wire are pressed on the metal sheet 23 in the mode of tightening the bolts 22, so as to realize the loop connection. The above wiring mode is simple in operation, easy to connect and disassemble, convenient in wiring and high in stability. In the embodiment, the grooves 211 include eight grooves, four of which are provided on the first side of the mounting seat 21, and the other four are provided on the second side of the mounting seat 21, that is, there are eight wiring points, that is, the wiring assembly 20 in the embodiment can be used for wiring of four groups of thermocouple wires and compensation lead wires. In actual application, one thermocouple needs to be connected with two groups of wires, that is, four wiring points are used. Therefore, in the embodiment, when one wiring box is used for wiring of one thermocouple, four wiring points need to be used, and the remaining four wiring points can be used as standby, so as to facilitate timely replacement in case of failure.

[0039] As shown in Figures 1 to 3 In the technical scheme of the embodiment, the mounting seat 21 is made of ceramic material. The ceramic material has good high-temperature resistance and can maintain stable structure in high-temperature environment, thereby avoiding structural failure and prolonging service life.

[0040] As shown in Figures 1 to 4 In the technical scheme of the embodiment, the projection of the wiring assembly 20 along the depth direction of the accommodating groove 1131 is located inside the projection of the box cover structure 12 along the depth direction of the accommodating groove 1131. The box cover structure 12 covers the entire accommodating groove 1131, and when the box cover structure 12 is connected with the box body structure 11, the two structures provide a relatively closed accommodating space for the wiring assembly 20. Since both the box cover structure 12 and the box body structure 11 are made of epoxy resin material, the internal accommodating space is not easily affected by external temperature fluctuations, which is beneficial to the measurement accuracy of the thermocouple.

[0041] As shown in Figure 1 and Figure 2As shown, in the technical scheme of the embodiment, the projection shape of the accommodating groove 1131 along the depth direction thereof is a "cross" shape. The accommodating groove 1131 of the structure makes the box body 113 have a platform for the connection hole on the surface of the box cover structure 12, and the box body structure 11 further comprises a first fixing hole 114 and a second fixing hole 115, the first fixing hole 114 is a stepped hole, the first fixing hole 114 penetrates the box body 113, and the fastener arranged in the first fixing hole 114 can fix the box body structure 11 at a suitable position of the platinum channel; the mounting seat 21 has a third fixing hole 212, the box body structure 11 has a fourth fixing hole, the fourth fixing hole is arranged correspondingly with the third fixing hole 212, and a thread is processed inside the fourth fixing hole, so that the fastener arranged in the third fixing hole 212 and the fourth fixing hole can fix the mounting seat 21 in the box body structure 11 to perform wiring; the box cover structure 12 has a fifth fixing hole, the fifth fixing hole is arranged correspondingly with the second fixing hole 115, a thread is processed on the inner wall of the second fixing hole 115, and the fastener arranged in the second fixing hole 115 and the fifth fixing hole can fix the box cover structure 12 and the box body structure 11 together, so that the wiring assembly 20 is located in the shell assembly 10.

[0042] According to another aspect of the present application, a wiring box is also provided, the platinum channel adopts the wiring box, the platinum channel comprises a mounting frame, a thermocouple and a compensation wire, the box body structure 11 is connected with the mounting frame, and the thermocouple and the compensation wire are connected with different wiring points respectively. After the wiring box is fixed on the mounting frame, the thermocouple and the compensation wire are wired according to requirements, since the shell assembly 10 of the wiring box is made of epoxy resin material, the epoxy resin material has good insulation and does not conduct electricity, so the thermocouple grounding does not occur.

[0043] As can be comprehended from the above, the high-temperature-resistant nonmetallic thermocouple junction box of the present application is composed of a nonmetallic thermocouple box (box body structure 11) and a ceramic junction terminal (junction assembly 20). The material of the box body is epoxy resin, which can resist 180℃ temperature. The box body of the thermocouple is composed of a base (box body structure 11) and a cover (box cover structure 12). The base and the cover are fixed and sealed by screws. The base of the thermocouple box has screw holes for fixing the box body, which facilitates the installation and fixation of the thermocouple box. The junction terminal of the high-temperature-resistant nonmetallic thermocouple junction box of the present application is made of ceramic, which is composed of a ceramic column and a metal junction terminal (screw 22 and metal sheet 23). The number of junctions is generally 2-4, which facilitates the junction of the thermocouple and is fixed inside the thermocouple box through the mounting hole. Since the thermocouple box is made of nonmetallic material, the heat conduction coefficient is small, and the temperature at the junction is less affected by external temperature fluctuations, which improves the measurement accuracy of the thermocouple. The high-temperature-resistant nonmetallic thermocouple junction box of the present application has two outlet terminals (first outlet 111 and second outlet 112) at the upper and lower parts, which can separate the thermocouple wire and the compensation lead wire through the hole. The on-site junction is flexible and convenient. The high-temperature-resistant nonmetallic thermocouple junction box of the present application is made of epoxy resin, which has good insulation performance. Since the thermocouple box is fixed on the steel structure of the platinum channel, the shell of the previous metal thermocouple box is grounded, and the thermocouple wire inside the box often causes grounding problems, which causes the platinum channel to pass through the thermocouple wire grounding fault. The platinum channel is not allowed to be grounded, and this problem of the thermocouple box has been a hidden danger for the safety of the platinum channel. The high-temperature-resistant nonmetallic thermocouple junction box of the present application has good insulation performance, which can avoid the grounding fault of the thermocouple wire of the platinum channel, improve the safety factor of the platinum channel, and ensure the safe operation of the platinum channel. The high-temperature-resistant nonmetallic thermocouple junction box of the present application is composed of a nonmetallic junction box and a ceramic junction terminal. The material of the thermocouple junction box is epoxy resin, which can resist 180℃ temperature and has good insulation and sealing performance. The high-temperature-resistant nonmetallic thermocouple junction box of the present application has a ceramic junction terminal inside, which has the advantages of high-temperature resistance, insulation and convenient junction. The high-temperature-resistant nonmetallic thermocouple junction box of the present application has two outlet terminal holes at the upper and lower parts, and the thermocouple wire and the compensation lead wire are separated into and out of the line, which has the advantages of anti-interference and flexible and convenient installation.
