Abstract
Description
Technical Field
[0001] The utility model belongs to the field of production equipment, and particularly relates to a steam pipeline heat preservation structure. Background Art
[0002] During the workshop production process, the water vapor generated by heating often needs to be exported and sent out. The generated water vapor is also part of the heat source. Directly discharging it will cause a large amount of energy waste. The best treatment method is to send it into other processes for heat exchange to achieve the reuse of energy, or send it into the processes that need to use water vapor for direct use, both of which can realize the subsequent utilization of water vapor. However, during the transportation process of water vapor, its energy loss will directly affect the final utilization rate of water vapor before reaching the next process. Therefore, a heat preservation pipeline is used to reduce the energy loss during the transportation of water vapor. The current solution is to wrap heat preservation materials on the outer side wall of the pipeline to achieve the heat preservation of the pipeline. However, for the water vapor generated by decentralized production, the transportation pipelines are also in a decentralized state, which will double the loss speed. Therefore, it is necessary to gather the decentralized pipelines to ensure that they are combined into one pipeline for transportation. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a steam pipeline heat preservation structure. By setting a conversion box, the scattered water vapor collected by a plurality of air inlets is gathered in the conversion box and then led out from the air outlet. The water vapor collected by one group of the air inlets is dispersed to the peripheral side walls of the conversion box through a heat preservation component to ensure that the periphery of the conversion box is wrapped with water vapor to keep the water vapor in the conversion box warm. Then, wrapping heat preservation materials outside the conversion box can minimize the temperature loss.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A steam pipeline heat preservation structure includes a conversion box and a box cover. A conversion cavity is arranged inside the conversion box. A plurality of air inlets communicating with the conversion cavity are arranged at the front end of the conversion box. An air outlet communicating with the conversion cavity is arranged at the rear end of the conversion box. A heat preservation component is arranged inside the conversion cavity. The heat preservation component surrounds the front side wall, left side wall, right side wall, bottom wall and rear side wall of the conversion cavity to form a heat preservation cavity. One group of the plurality of air inlets communicates with the heat preservation cavity. The heat preservation component is provided with a ventilation opening pointing to the air outlet on the rear side wall of the conversion cavity. The box cover covers and is detachably connected to the upper opening of the conversion box. A heat preservation layer is arranged at the bottom of the box cover.
[0006] The heat insulation component includes a left flow channel, a right flow channel and a bottom flow channel. The left flow channel is C-shaped and encloses the front side wall, the left side wall and the rear side wall of the conversion cavity. One group of a plurality of the air inlets is communicated with the left flow channel. The right flow channel is L-shaped and encloses the right side wall and the rear side wall of the conversion cavity. The bottom flow channel encloses the bottom wall of the conversion cavity. The left and right ends of the bottom flow channel are respectively communicated with the left flow channel and the right flow channel. A ventilation port pointing to the air outlet is arranged at the connection of the left flow channel and the rear side wall. A ventilation port pointing to the air outlet is arranged at the connection of the right flow channel and the rear side wall. A sealing plate is arranged on the ventilation port of the left flow channel, and a plurality of ventilation holes penetrating the left flow channel are arranged at the upper end of the sealing plate.
[0007] For the steam pipeline heat insulation structure adopting this structure, the conversion box is used to collect the water vapor collected by a plurality of air inlets, converge in the conversion cavity and then transfer it to the next process for use from the air outlet. After wrapping the heat insulation material on the outer side wall of the conversion box, the conversion box can be preliminarily insulated. In order to avoid the temperature loss in the conversion box to the greatest extent, a heat insulation component is added. The left flow channel included in the heat insulation component is C-shaped and encloses the front side wall, the left side wall and the rear side wall of the conversion cavity. One group of a plurality of the air inlets is communicated with the left flow channel. The right flow channel is L-shaped and encloses the right side wall and the rear side wall of the conversion cavity. The bottom flow channel encloses the bottom wall of the conversion cavity. The left and right ends of the bottom flow channel are respectively communicated with the left flow channel and the right flow channel. Therefore, the water vapor carried by one group of air inlets enters the left flow channel through the connection with the left flow channel, then enters the bottom flow channel and the right flow channel in sequence, realizing the full coverage of the conversion box. The redundant water vapor escapes from the ventilation ports on the left flow channel and the right flow channel and enters the air outlet. Since the air inlet is close to the leftmost end, in order to avoid a large amount of water vapor passing only through the left flow channel and only a small part passing through the bottom flow channel and the right flow channel, resulting in incomplete coverage of the conversion box by the water vapor, a sealing plate is added to the ventilation port of the left flow channel, and a plurality of ventilation holes are arranged at the upper end of the sealing plate to reduce the water vapor flow rate in the left flow channel, forcing more water vapor to escape from the ventilation port of the right flow channel. The upper end of the conversion box is covered with a cover plate, and the heat insulation layer at the bottom of the cover plate can ensure an overall heat insulation effect of the conversion box, achieving the second layer of heat insulation with the lowest loss to reduce the temperature loss of the water vapor in the conversion box.
[0008] Furthermore, the heat insulation component further includes a diversion member. The diversion member includes a water outlet, and the water outlet is arranged on the outer side wall of the conversion box and communicated with the bottom flow channel. An inclined part is arranged at the connection of the bottom flow channel and the bottom wall, and the inclined part slopes downward from front to back towards the water outlet. A water discharge hole communicating the conversion cavity and the heat insulation cavity is arranged on the bottom flow channel.
[0009] Compared with the prior art, the advantages of the present utility model are as follows: By wrapping a heat-insulating material on the outer side wall of the conversion box, a preliminary heat-insulating effect is achieved on the conversion box. Then, a left flow channel, a right flow channel, and a bottom flow channel are added in the conversion cavity to form a continuously penetrating heat-insulating cavity. By connecting to a group of several air inlets, the water vapor therein comprehensively wraps the conversion box. A cover plate is closed on the upper end of the conversion box, and the heat-insulating layer at the bottom of the cover plate can ensure that the conversion box forms an overall heat-insulating effect, achieving the second layer of heat insulation with the lowest loss to reduce the temperature loss of the water vapor in the conversion box.

[0023] Furthermore, the heat insulation component 14 further includes a diversion member 145. The diversion member 145 includes a water outlet 1451.

[0024] Description of the working mode of the utility model:
[0025] For the steam pipeline heat preservation structure adopting this structure, the conversion box 1 is used to collect the water vapor collected by a plurality of air inlets 12, converge in the conversion cavity 11 and then transfer it from the air outlet 13 to the next process for use. After wrapping the outer side wall of the conversion box 1 with heat preservation material, a preliminary heat preservation effect can be achieved on the conversion box 1. In order to maximize the avoidance of temperature loss in the conversion box 1, a heat preservation component 14 is added. The left flow channel 141 included in the heat preservation component 14 is in a C shape, enclosing the front side wall, left side wall and rear side wall of the conversion cavity 11. One group of the plurality of air inlets 12 is communicated with the left flow channel 141, while the right flow channel 142 is in an L shape to enclose the right side wall and rear side wall of the conversion cavity 11, and the bottom flow channel 143 is enclosed on the bottom wall of the conversion cavity 11. The left and right ends of the bottom flow channel 143 are respectively communicated with the left flow channel 141 and the right flow channel 142. Therefore, the water vapor carried by one group of air inlets 12 enters the left flow channel 141 through the communication with the left flow channel 141, and then enters the bottom flow channel 143 and the right flow channel 142 in sequence, realizing the comprehensive coating of the conversion box 1. The redundant water vapor escapes through the ventilation openings 144 on the left flow channel 141 and the right flow channel 142 and enters the air outlet 13. Since the air inlet 12 is close to the leftmost end, in order to avoid a large amount of water vapor passing only through the left flow channel 141 and only a small part passing through the bottom flow channel 143 and the right flow channel 142, resulting in incomplete wrapping of the conversion box 1 by the water vapor, a sealing plate 1411 is added to the ventilation opening 144 of the left flow channel 141, and a plurality of ventilation holes 1412 are arranged at the upper end of the sealing plate 1411 to reduce the flow rate of the water vapor in the left flow channel 141, forcing more water vapor to escape through the ventilation opening 144 of the right flow channel 142. The upper end of the conversion box 1 is covered with a cover plate, and the heat preservation layer at the bottom of the cover plate can ensure an overall heat preservation effect of the conversion box 1, achieving the second layer of heat preservation with the lowest loss to reduce the temperature loss of the water vapor in the conversion box 1.
[0026] During the shutdown process, the water vapor in the pipeline will condense into water after cooling, and the water vapor retained in the conversion box 1 is no exception. Therefore, the condensed water will accumulate at the bottom of the conversion cavity 11 or at the bottom of the bottom flow channel 143. Over time, the increase in accumulated water will cause the bottom flow channel 143 to lose the space for conducting water vapor, which will in turn affect the heat preservation effect of the conversion box 1. Therefore, it is necessary to timely drain the accumulated condensed water. For this reason, a diversion component is provided. An outlet 1451 communicating with the bottom flow channel 143 is provided on the outer side wall of the conversion box 1, which is used to drain the condensed water accumulated in the bottom flow channel 143. In order to ensure that the condensed water can be smoothly drained from the outlet 1451, an inclined portion 1452 inclined from front to back towards the outlet 1451 is provided in the bottom flow channel 143. Therefore, the accumulated condensed water can flow to the position of the outlet 1451 under the action of gravity, facilitating the drainage of the condensed water. Since condensed water may also accumulate in the conversion cavity 11, a drain hole 1453 is provided on the bottom flow channel 143. The drain hole 1453 communicates the conversion cavity 11 and the heat preservation cavity, and can introduce the condensed water in the conversion cavity 11 into the bottom flow channel 143 through the drain hole 1453, and the drain hole 1453 will not affect the flow and heat preservation of the water vapor in the heat preservation cavity.
[0027] The beneficial effects of the present utility model are as follows: By wrapping heat preservation materials on the outer side wall of the conversion box 1, a preliminary heat preservation effect is achieved on the conversion box 1. Then, a left flow channel 141, a right flow channel 142 and a bottom flow channel 143 are additionally provided in the conversion cavity 11 to form a continuous and through heat preservation cavity. By connecting a group of several air inlets 12, the water vapor therein comprehensively wraps the conversion box 1. The upper end of the conversion box 1 is covered with a cover plate. Through the heat preservation layer at the bottom of the cover plate, it can be ensured that the conversion box 1 forms an overall heat preservation effect, achieving the second layer of heat preservation with the lowest loss to reduce the temperature loss of the water vapor in the conversion box 1.
