[0036] Embodiment one

[0037] As shown in Figures 1 to 5 A heating baffle brick for forming photovoltaic glass, comprising a brick body 1, a heating groove 2 is formed in the brick body 1 near the working face side wall, and a heating element 3 is arranged in the heating groove 2; and a baffle plate 4, at least the working face side wall of the brick body 1 is provided with the baffle plate 4, which is arranged in contact with the heating element 3.

[0038] Specifically, the working face is the side in contact with the glass liquid. Preferably, baffle plates 4 are arranged on both sides of the brick body 1, and the baffle plates 4 and the brick body 1 are fixed by fasteners. The specific structure is the same as the baffle structure in the Chinese patent CN202421019923.7 applied by the applicant, and will not be described here.

[0039] AsFigure 2 As shown, the heating grooves 2 are arranged in groups and horizontally arranged, and the inside of the heating groove 2 is provided with a structure matching the shape of the heating element 3.

[0040] In some embodiments, in order to achieve uniform heating of the working surface of the curb brick, the heating elements 3 are uniformly arranged to cover the sidewall of the working surface, and of course, the arrangement can be set according to the actual working condition requirements.

[0041] The advantage of such arrangement is that the heating elements 3 in the heating groove 2 can more uniformly heat the curb plate on the working surface of the brick body 1, and the horizontal arrangement can ensure that the distribution of the heating elements 3 remains stable.

[0042] As shown in Figure 3 The heating groove 2 at least partially penetrates the sidewall of the working surface of the brick body 1; the heating groove 2 includes a first groove part 21 for accommodating the heating element 3 and a second groove part 22 penetrating the sidewall of the working surface of the brick body 1 and arranged in communication with the first groove part 21, and the first groove part 21 matches the shape of the heating element 3.

[0043] In some embodiments, in order to improve the heating effect and processing convenience, it is preferred that one side of the heating groove 2 completely penetrates the sidewall of the working surface of the brick body 2 along the arrangement direction of the heating element 3. Of course, in some embodiments, the heating groove 2 can also be intermittently penetrated, which can not only ensure the convenience of arrangement and processing, but also protect the heating element 3 from direct contact with the outside.

[0044] In addition, the shape matching makes the heat transfer more uniform and efficient, and the heating element will not be damaged due to local overheating or frequent thermal stress changes.

[0045] As shown in Figure 5 The vertical opening size of the second groove part 22 is not greater than the vertical opening size of the first groove part 21.

[0046] It should be noted that such arrangement can better protect the heating element 3 from falling out of the first groove part 21 and falling into the second groove part 22, thereby directly contacting the outside and causing safety hazards, avoiding short circuit phenomenon and affecting production progress.

[0047] As shown in Figure 2 The heating groove 2 horizontally penetrates the mating surface 11 of the brick body 1 and the side surface 12 opposite to the mating surface 11.

[0048] In combination with Figure 3 , the through arrangement facilitates the rapid processing of the brick body 1 and improves production efficiency. When arranging the heating element 3, it can be more convenient to pull and place or disassemble from both sides.

[0049] As Figure 5 shown, the side surface 12 is provided with mounting grooves 121 for mounting the leading end and the trailing end of the heating element 3 respectively, and the mounting grooves 121 are in transition communication with the corresponding heating grooves 2.

[0050] It is worth mentioning that the positions of the leading end and the trailing end are not unique and can be interchanged, which does not affect the arrangement of the heating element 3, and the leading end and the trailing end can also protect the two ends of the heating element 3.

[0051] As Figure 3 shown, the transition grooves 111 are provided on the matching surface 11 and the side surface 12, and the transition grooves 111 are used to accommodate the part of the heating element 3 that realizes the reversing between the adjacent two heating grooves 2.

[0052] In order to ensure safety, the depth of the transition groove 2 is preferably not less than the outer dimension of the heating element 3, so that the heating element 3 can be completely placed in the transition groove, thereby improving safety.

[0053] As Figure 1 shown, the protective structure is one or both of a refractory filler or a protective plate 6 on at least the part of the brick body 1 where the heating element 3 is exposed; in some embodiments, the baffle plate 4 and the protective plate 6 can be selected to be heat-resistant steel.

[0054] The protective structure can protect the heating element and the operator, and covering the exposed heating element also increases the overall aesthetics, and heat-resistant steel can withstand high temperatures, reducing equipment failures and maintenance costs caused by high temperatures.

[0055] Embodiment Two

[0056] As Figures 6 to 8 shown, the same or corresponding parts as in Embodiment One are denoted by the same reference numerals as in Embodiment One, and for the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this embodiment and Embodiment One is that, as Figure 4 , 5 shown, a partition plate 5 is further provided between the baffle plate 4 and the heating element 3 for limiting the heating element 3; and heat transfer holes 51 are provided on the partition plate 5 corresponding to the positions of the heating grooves 2.

[0057] The partition plate 5 can be selected to be a non-metallic material that can withstand high temperatures, such as aluminum oxide or aluminum silicate fiber board, and is closely arranged with the second groove portion 22. The partition plate 5 can further protect the heating element 3 from directly contacting the baffle plate 4, and at the same time, the heat inside the heating groove 2 can be better utilized, reducing the energy input required to maintain the temperature, thereby improving the thermal efficiency.

[0058] In addition, it is preferable that the heat transfer holes 51 completely penetrate the partition plate 5 along the arrangement direction of the heating groove 2. In some embodiments, a group of heat transfer holes 51 can also be designed as multiple spaced through holes.

[0059] In some preferred embodiments, the heating groove 4 may be set as only the first groove 41, the partition 5 is set close to the opening of the first groove 41, and the vertical diameter of the heat transfer hole 51 is smaller than the diameter of the opening of the first groove 41, thereby reducing the distance between the heating element 3 and the baffle plate 4 and improving the heating efficiency.

[0060] Example 3

[0061] like Figure 9 As shown, this embodiment provides a glass forming edge block with heating function. The transition groove 2 is hidden inside the brick body 1, and the reversing part of the heating element 3 is embedded in the brick body 1 to avoid being exposed to the outside of the brick body 1.

[0062] Example 4

[0063] like Figure 10 As shown, this embodiment provides a temperature control device, including an electrical control box 7. The device is used to control and adjust the temperature of the edge brick. A thermocouple 71 is also installed inside the brick body 1. The thermocouple 71 and the heating element 3 are both electrically connected to the electrical control box 7.

[0064] It should be noted that thermocouple 71 is existing technology and will not be described in detail here. Thermocouple 71 penetrates the brick body 1, and its detection end is close to the working surface to monitor the working temperature of the brick body. It actively heats the brick body through the heating element 3 to offset the heat dissipation, thus solving the problem of low working surface temperature and achieving a high degree of automation.

[0065] In some embodiments, the heating element 3 can be selected as a resistance heating wire, or as a rod-shaped electric heating element such as a silicon molybdenum rod, which is low in cost and easy to maintain.

[0066] In addition, the heating element 3 and the brick body 1 can also be integrally cast and molded. The heating element is embedded in the heating groove 2 of the brick body 1, so that the heating wire is pre-embedded and fixed. The heating wire will not move or overlap due to heating when energized, and its lifespan will be longer.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
