Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of industrial equipment heat preservation, in particular to a heat conduction structure for tracing heat that is convenient for installation. Background Art:
[0002] In the industrial field, it is necessary to trace heat for industrial pipelines to maintain the temperature of the pipelines, so as to ensure the fluidity of the liquid inside the pipelines and avoid the crystallization and solidification of the liquid inside the pipelines from blocking the pipelines. Generally, the method of laying tracing heat pipes outside the industrial pipelines is adopted for tracing heat. High-temperature steam or heat-conducting oil flows inside the tracing heat pipes, so as to maintain the temperature of the industrial pipelines. Since the industrial pipelines and the tracing heat pipes are in line contact, the heat conduction effect is poor. To solve this problem, generally, a combination of a tracing heat pipe and a heat conduction plate is used for tracing heat. However, when installing the tracing heat pipe and the heat conduction plate, it is difficult to fix the positions of the tracing heat pipe and the heat conduction plate. After using for a period of time, the phenomenon of displacement of the tracing heat pipe and the heat conduction plate occurs, resulting in uneven tracing heat and affecting the tracing heat effect. Summary of the Invention:
[0003] In order to solve the problem of poor installation and fixing effect of industrial pipeline tracing heat, the utility model provides a heat conduction structure for tracing heat that is convenient for installation, which includes a tracing heat pipe and "L"-shaped heat conduction plates arranged on both sides of the tracing heat pipe. The feature is that a fastening structure is arranged between two adjacent heat conduction plates. The fastening structure is composed of a bolt, a nut matching with the bolt, and a pressing component arranged on the bolt. Rotating the nut on the bolt can adjust the position of the pressing component between two adjacent heat conduction plates, and then squeeze the fastening structure between two adjacent heat conduction plates, thereby squeezing and closely fitting two adjacent heat conduction plates on the corresponding tracing heat pipe respectively. The tracing heat pipe and the heat conduction plates arranged uniformly around the pipeline to be traced heat are mutually attached and squeezed to form a stable circular tracing heat conduction structure, realizing the fixation of the tracing heat pipe and the heat conduction plate. The pressing component is one of a bolt cap sleeve or a bolt column pressing plate, and the bolt also includes a bolt column and a bolt cap.
[0004] The heat conduction plate includes a heat-receiving side edge and a heat-transferring bottom edge. The heat-receiving side edge is attached to the outer wall of the tracing heat pipe and receives the heat of the tracing heat pipe, and then transfers the heat to the heat-transferring bottom edge. The heat-transferring bottom edge is attached to the outer wall of the pipeline to be traced heat and transfers the heat transferred from the heat-receiving side edge to the pipeline to be traced heat.
[0005] When the pressing component is a bolt cap sleeve, the length of the bolt is less than the distance between the side walls of two adjacent heat transfer bottom edges. The sum of the lengths of the bolt and the bolt cap sleeve is greater than the distance between the side walls of two adjacent heat transfer bottom edges. The bolt is horizontally placed between two adjacent heat transfer bottom edges, and the end of the bolt post is pressed against the side wall of one of the heat transfer bottom edges. The bolt cap sleeve is sleeved on the bolt, and its front end is sleeved on the periphery of the bolt cap. The nut is arranged at the rear side of the bolt cap sleeve. When the nut is tightened towards the bolt cap, the nut pushes the bolt cap sleeve to move towards the bolt cap until the front end of the bolt cap sleeve contacts and presses against the side wall of the other heat transfer bottom edge. At this time, the end of the bolt and the front end of the bolt cap sleeve respectively press against the side walls of two adjacent heat transfer bottom edges, thereby squeezing the fastening structure between two adjacent heat conducting plates.
[0006] When the pressing component is a bolt post pressing plate, the length of the bolt is greater than the distance between the side walls of two adjacent heat transfer bottom edges. At this time, for the "L"-shaped heat conducting plate installed forward on one side of the traced pipe, a bolt mounting plate is longitudinally arranged on the side wall of its heat transfer bottom edge, and a bolt hole is arranged on the bolt mounting plate. For the "L"-shaped heat conducting plate installed backward on one side of the traced pipe, a bolt pressing plate is longitudinally arranged on the side wall of its heat transfer bottom edge. The bolt passes through the bolt hole, the bolt cap is located on the left side of the bolt mounting plate, the nut is screwed on the bolt and is located on the right side of the bolt mounting plate. The bolt post pressing plate is sleeved on the end of the bolt post. By tightening the nut towards the bolt mounting plate, the length of the bolt post on the right side of the bolt mounting plate is continuously extended until the bolt post pressing plate contacts and presses against the other bolt pressing plate. At this time, the end of the bolt post pressing plate and the front end of the nut respectively press against the bolt pressing plate and the bolt mounting plate, thereby squeezing the fastening structure between two adjacent heat conducting plates.
[0007] The inner diameter of the bolt cap sleeve is the same as the outer diameter of the bolt cap. A retaining ring is arranged at the rear end of the bolt cap sleeve. The inner diameter of the retaining ring is less than the outer diameter of the bolt cap and is the same as the outer diameter of the bolt. The outer diameter of the retaining ring is greater than or equal to the outer diameter of the nut.
[0008] The fitting surface of the heated side edge with the outer wall of the traced pipe is a semi-circular arc surface with the same radius as the traced pipe, so that the heated side edge can be closely fitted with the outer wall of the traced pipe. The fitting surface of the heat transfer bottom edge with the pipe to be traced is an arc surface with the same radius as the pipe to be traced, so that the heat transfer bottom edge can be closely fitted with the outer wall of the pipe to be traced.
[0009] The outer side of the heat conduction plate is covered with heat insulation cotton to prevent heat dissipation, and the tracing pipe, the heat conduction plate and the heat insulation cotton are integrally fixed by binding straps.
[0010] The beneficial effects of the utility model are as follows:
[0011] 1. The fastening structure can fix the distance between multiple tracing pipes to ensure uniform tracing heat.
[0012] 2. The fastening structure is used to fix the heat conduction plate, which is convenient for installation, and improves the fitting effect between the heat conduction plate and the tracing pipe, further enhancing the heat conduction effect.
[0013] 3. The heat conduction plate is thermally insulated by heat insulation cotton, reducing heat dissipation to the outside.
[0014] The above advantages make this new type have obvious advantages in the field of industrial equipment heat preservation. Description of the drawings:

The tracing heating pipe 1 and the heat-conducting plates 2 uniformly arranged around the pipe 5 to be traced are mutually attached and extruded to form a stable circular tracing heating and heat-conducting structure, realizing the fixation of the tracing heating pipe 1 and the heat-conducting plate 2.

At this time, the end of the bolt 3 and the front end of the bolt cap sleeve 6 respectively press against the side walls of two adjacent heat-transferring bottom edges 9, and then the fastening structure is extruded between two adjacent heat-conducting plates 2.

At this time, the end of the bolt column pressing plate 7 and the front end of the nut 4 are respectively pressed on the bolt pressing plate 13 and the bolt mounting plate 12, thereby squeezing the fastening structure between two adjacent heat conducting plates 2.
