Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf storage, in particular to a heat recovery type air-conditioning room drainage pipe antifreeze structure. Background Art

[0002] In tobacco production and processing, tobacco leaves often need to be stored in a warehouse for aging for about two years. During these two years, the ambient temperature and humidity in the warehouse need to be kept within the appropriate range. Heating and humidity control air-conditioning equipment needs to be used in the warehouse to form an air-conditioned room.

[0003] The air-conditioning room maintains a constant temperature and humidity, and a large amount of water often condenses at the air-conditioning equipment, so the excess water needs to be discharged through the drain pipe. Drainage is more convenient in summer, but once winter comes, especially in the past two years, extreme weather has occurred frequently in winter and low temperatures have lasted for a long time, causing the drain pipe to freeze and become blocked, resulting in the inability to drain water in the air-conditioning room in time. The tobacco leaves are prone to moisture and mold, affecting the quality of the leaves.

[0004] Currently, there are many devices and technologies for preventing building drain pipes from freezing. For example, Chinese patent invention patent CN104264740A proposes a drain pipe antifreeze system, which consists of a drain pipe water inlet interface, an elastic convergent guide port, a controller, an electric heater, a water sensor, and an atmospheric temperature sensor. The drain pipe water inlet interface is an inverted trapezoidal structure, with the bottom of the drain pipe water inlet interface inserted into the drain pipe; the elastic convergent guide port guides the flowing water to the central axis of the drain pipe, allowing the flowing water to fall rapidly to the vertically installed drain pipe outlet in a free fall manner. When the amount of flowing water is large, the elastic convergent guide port can expand accordingly under the action of water, allowing a large amount of water to pass smoothly; a water sensor is provided on the inner wall of the drain pipe water inlet interface, and an electric heater is arranged on the inner wall of the drain pipe water inlet interface; the signal receiving end of the controller is connected to the water sensor and the atmospheric temperature sensor, and the output end of the controller is connected to the electric heater. The above invention solves the problem of freezing in drain pipes, effectively protects buildings, and has safe and reliable performance, especially suitable for use in northern regions.

[0005] However, the above-mentioned drainage pipe antifreeze system still has the following disadvantages: the structure is complex, and the constant temperature and humidity in the air-conditioning room where tobacco leaves are aged make the drainage pipe not drain water continuously in large quantities, but drain water intermittently in small quantities, causing the drainage pipe to freeze more easily and freeze slowly layer by layer. The above-mentioned invention cannot accurately and effectively obtain the water temperature in the drainage pipe, and the heat energy of the electric heater is mostly wasted, resulting in high cost of use and poor antifreeze effect.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient heat recovery air-conditioning room drainage pipe anti-freezing structure. Utility Model Content

[0030] Example 1: Figures 1 to 3 The figure shown is only one of the embodiments of the present invention, a heat recovery type air-conditioning room drain pipe antifreeze structure, including a drain pipe 1 arranged on the wall 4 and an exhaust pipe 2 arranged on the outside of the drain pipe 1, an exhaust fan 23 is arranged in the exhaust pipe 2, a heat conductive block 3 is arranged on the outer wall of the drain pipe 1, and a heat collecting plate 33 is provided at one end of the heat conductive block 3 close to the inner side of the wall 4.

[0031] In the present invention, the drain pipe 1 is arranged on the wall 4 for drainage, and the exhaust pipe 2 is the exhaust pipe of the fresh air system of the air-conditioning room, and at least a part of the exhaust pipe 2 is located on the outside of the drain pipe 1. Specifically, the part of the drain pipe 1 leaking out of the outside of the wall 4 is located on the inside of the exhaust pipe 2, so that the heat energy of the higher-temperature gas discharged by the exhaust pipe 2 is exchanged to the drain pipe 1, and the drain pipe 1 is prevented from freezing in the form of heat recovery; further, a heat-conducting block 3 is provided on the outer wall of the drain pipe 1. In fact, a heat-conducting block 3 is provided on the outside of the part of the drain pipe 1 located on the inner side of the wall 4. The heat-conducting block 3 can exchange the heat energy of the high-temperature environment in the air-conditioning room to the drain pipe 1, and further prevent the drain pipe 1 from freezing in the form of heat recovery.

[0032] In fact, the drainage pipe 1 includes a horizontal pipe 11 located at the wall 4, an upper probe 12 arranged at one end of the horizontal pipe 11 close to the inner side of the wall 4, and a lower probe 13 arranged at one end of the horizontal pipe 11 close to the outer side of the wall 4. The exhaust pipe 2 includes a first exhaust pipe 21 located outside the horizontal pipe 11 and a second exhaust pipe 22 located outside the lower probe 13. The exhaust fan 23 is arranged at the end of the second exhaust pipe 22 away from the first exhaust pipe 21.

[0033] The upper end of the upper probe 12 is connected to the water outlet pipes of several air conditioners, and the conditioned water flows out after passing through the upper probe 12, the horizontal pipe 11 and the lower probe 13. The drain pipe 11 is generally horizontally arranged and can also be slightly lower near one end of the lower probe 13 to allow the conditioned water to flow out.

[0034] Similarly, the heat-conducting block 3 includes a first heat-conducting block 31 located on the outside of the horizontal tube 11 and a second heat-conducting block 32 located on the outside of the upper probe tube 12. The heat collecting plate 33 is located at the end of the second heat-conducting block 32 away from the first heat-conducting block 31. It should be noted that the heat collecting plate 33 can extend to the vicinity of the heat source in the air-conditioning room to further recycle and utilize the heat energy in the air-conditioning room.

[0035] Example 2, still as Figures 1 to 3 The figure shown is only one of the embodiments of the present invention. Based on the first embodiment, the present invention provides a heat recovery type air-conditioning room drainage pipe antifreeze structure, wherein the end of the first heat conductive block 31 away from the second heat conductive block 32 does not exceed the outer surface of the wall 4, thereby preventing the heat energy of the first heat conductive block 31 from being lost.

[0036] Furthermore, the heat conducting block 3 is an integrally formed metal part.

[0037] In the present invention, the number of the exhaust fan 23 is at least one.

[0038] In order to further prevent the drain pipe from freezing, a thermometer electrically connected to the exhaust fan 23 is provided in the drain pipe 1. The lower the temperature in the drain pipe 1, the higher the exhaust power of the exhaust fan 23 and the stronger the heat exchange rate.

[0039] Finally, a heat insulation layer is provided on the outside of the exhaust pipe 2, and the drain pipe 1 is a heat conducting member.

[0040] The utility model discloses a heat recovery type air-conditioning room drainage pipe antifreeze structure, which has a simple structure, effectively utilizes the constant temperature characteristic of the tobacco aging air-conditioning room, arranges the fresh air exhaust of the room outside the drainage pipe, effectively recovers the heat of the air, and then further guides the high temperature in the room to the outside of the drainage pipe through the heat conduction block, thereby enhancing heat recovery, low use cost and good antifreeze effect.
