Description

Technical Field

[0001] The utility model relates to the technical field of pipeline heat preservation, in particular to a uniform heating compensation device. Background Technique

[0002] A thermal pipeline is a pipeline system for transporting heat energy or steam. It is usually made of materials such as steel or plastic and is used to transport heat energy from an energy production device to a place where heating is required. During the process of heat transfer through the pipeline, a part of the heat will be dissipated from the side wall of the pipeline. Thus, when the heat enters other devices from the output end of the pipeline, due to the reduction in heat, the situation of insufficient thermal drive will occur. Therefore, a heating compensation device needs to be provided in the front side of the output end of the pipeline to ensure that the temperature of the input heat meets the requirements.

[0003] Currently, the installation steps of the existing heating compensation device are relatively cumbersome, inconvenient to connect and fix with the pipeline, reducing the installation efficiency, and the sealing performance is average after installation; it is also difficult for the existing heating components to ensure uniform heating of the side wall of the pipeline, and there is a situation of uneven heating, resulting in a reduction in the heat transfer effect. Therefore, a uniform heating compensation device is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of uneven heating compensation of the side wall of the pipeline, low installation efficiency, and average sealing performance after installation in the existing technology, and to propose a uniform heating compensation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

An installation plate is fixedly connected to the middle of the heating wire. Connecting grooves are provided on the side walls of both installation plates. Conductive plates are respectively slidably connected in the two connecting grooves. A first spring is fixedly connected between the side wall of the conductive plate and the connecting groove. A connecting wire is fixedly connected to the side wall of the conductive plate in the lower shell.

[0007] To improve the heating effect, preferably, the end face of the conductive plate in the lower shell is concave, the end face of the conductive plate in the upper shell is convex, and the concave and convex shapes are adapted to each other.

[0012] Further, lower pressure grooves are respectively formed on both sides of the lower shell, a lower pressure strip is slidably connected in the lower pressure groove, and a third spring is fixedly connected between the lower pressure strip and the lower pressure groove.

[0025] Embodiment:

[0026] Refer to Figures 1 - 4, a uniformity heating compensation device, including an upper housing 1 and a lower housing 2. The upper housing 1 and the lower housing 2 are rotatably connected through a hinge. Temperature sensing grooves 3 are provided in both the upper housing 1 and the lower housing 2, and a temperature sensor 31 is fixedly connected in the temperature sensing groove 3. Heating grooves 4 are provided in both the upper housing 1 and the lower housing 2, and heating resistance wires 41 are fixedly connected in the heating grooves 4. A mounting plate 42 is fixedly connected to the middle of the heating resistance wire 41. Communication grooves 5 are provided on the side walls of the two mounting plates 42. Conductive plates 51 are respectively slidably connected in the two communication grooves 5. A first spring 52 is fixedly connected between the side wall of the conductive plate 51 and the communication groove 5. A conducting wire 53 is fixedly connected to the side wall of the conductive plate 51 in the lower housing 2. The end face of the conductive plate 51 in the lower housing 2 is concave, and the end face of the conductive plate 51 in the upper housing 1 is convex, and the concave and convex shapes are adapted to each other. When the upper housing 1 and the lower housing 2 are closed and fixed, the two conductive plates 51 will be aligned and clamped and pressed against each other. Thereafter, under the resilience of the first spring 52, the two conductive plates 51 will be in a tightly fitting state, which also makes the two heating resistance wires 41 communicate with each other, expanding the heating area and realizing the full heating of the pipe side wall. Subsequently, during the process of transporting heat in the pipe, when the temperature sensor 31 detects that the temperature transmitted from the pipe side wall is less than the set threshold, the conducting wire 53 will form a circuit and transmit the current to the two heating resistance wires 41. In this way, the two heating resistance wires 41 will start to heat up, forming a wrapped mesh heating effect to uniformly heat the pipe side wall, ensuring the temperature after heat transmission in the pipe and improving the utilization effect of subsequent heat.

[0027] Refer to Figures 1 - 4 , a clamping sleeve 6 is fixedly connected to the side wall of the upper housing 1, and a clamping belt 61 is fixedly connected to the side wall of the lower housing 2. The clamping sleeve 6 and the clamping belt 61 are vertically aligned. Positive magic tapes 62 and negative magic tapes 63 are respectively fixedly connected to the side wall of the clamping belt 61, and the positive magic tape 62 and the negative magic tape 63 are adhesively connected. The clamping sleeve 6 and the clamping belt 61 are provided in three groups at equal intervals. Using the adhesive connection between the positive magic tape 62 and the negative magic tape 63, it is very convenient to fix between the upper housing 1 and the lower housing 2, effectively improving the convenience of installation between the upper housing 1 and the lower housing 2.

[0028] Refer to Figure 3 , Figure 4, upper pressing grooves 7 are formed on both sides of the upper shell 1. Upper pressing bars 71 are slidably connected in the upper pressing grooves 7. A second spring 72 is fixedly connected between the upper pressing bars 71 and the upper pressing grooves 7. Lower pressing grooves 8 are formed on both sides of the lower shell 2. Lower pressing bars 81 are slidably connected in the lower pressing grooves 8. A third spring 82 is fixedly connected between the lower pressing bars 81 and the lower pressing grooves 8. The end faces of the upper pressing bars 71 are provided with convex semi-circular arcs, and the end faces of the lower pressing bars 81 are provided with concave semi-circular arcs. The upper pressing bars 71 and the lower pressing bars 81 are engaged with each other. When the upper shell 1 and the lower shell 2 are closed and fixed, the upper pressing bars 71 and the lower pressing bars 81 will be engaged and fixed with each other. Subsequently, by means of the resilience of the second spring 72 and the third spring 82, the upper pressing bars 71 and the lower pressing bars 81 will be closely attached to each other, thereby effectively improving the sealing performance between the upper shell 1 and the lower shell 2 after fixation, avoiding heat loss, and improving the heating effect.

[0029] Referring to Figures 1 - 4 , in the present utility model, during use, the upper shell 1 and the lower shell 2 are sleeved on the side wall of the pipeline. At this time, the upper pressing bars 71 and the lower pressing bars 81 will be engaged and fixed with each other. Subsequently, the three snap belts 61 are passed through the snap sleeves 6, so that the positive magic tape 62 and the negative magic tape 63 are adhered to each other, thereby realizing the fixation of the upper shell 1 and the lower shell 2, and stably wrapping them on the side wall of the pipeline. The upper pressing bars 71 and the lower pressing bars 81 will be closely attached to each other by means of the resilience of the second spring 72 and the third spring 82, thereby effectively improving the sealing performance between the upper shell 1 and the lower shell 2 after fixation, avoiding heat loss, and improving the heating effect; moreover, when the upper shell 1 and the lower shell 2 are closed and fixed, the two conductive plates 51 on both sides will be aligned and engaged with each other and pressed against each other. Subsequently, under the resilience of the first spring 52, the two conductive plates 51 on both sides will be in a closely attached state, thereby also enabling the two heat resistance wires 41 to be connected to each other. Then, during the process of transporting heat in the pipeline, when the temperature sensor 31 detects that the temperature transmitted from the side wall of the pipeline is less than the set threshold, the energized wire 53 will form a circuit and transmit the current to the two heat resistance wires 41. In this way, the two heat resistance wires 41 will start to heat up, thereby forming a wrapped mesh heating effect and uniformly heating the side wall of the pipeline to ensure the temperature of the heat transmitted in the pipeline and improve the utilization effect of the subsequent heat.
