Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf storage, in particular to an antifreeze structure for drainage pipes in air-conditioning rooms. 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 where the tobacco leaves are stored need to be kept within an appropriate range. Heating and humidity control air-conditioning equipment is needed 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 climates have occurred frequently in winter and low temperatures have lasted for a long time, causing the drain pipe to freeze and become blocked, making it impossible 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] There are many equipment and technologies for antifreeze of building drain pipes. For example, Chinese patent invention patent CN104264740A proposes a drain pipe antifreeze system, which consists of a drain pipe water inlet interface, an elastic convergence 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, and the bottom of the drain pipe water inlet interface is inserted into the drain pipe; the elastic convergence guide port guides the flowing water to the central axis position of the drain pipe, so that the downstream water falls quickly to the vertically installed drain pipe outlet position in a free fall manner. When the downstream water volume is large, the elastic convergence 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 freezing problem in the drain pipe, effectively protects the building, has safe and reliable performance, and is particularly suitable for use in northern regions.

[0005] However, the above-mentioned drain 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 makes the drain pipe drain not a continuous large amount of water, but an intermittent small amount of water, which makes the drain pipe more likely to freeze, and freezes slowly layer by layer. The above-mentioned invention cannot accurately and effectively obtain the water temperature in the drain 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 antifreeze structure for the drainage pipes in the air-conditioning room. Utility Model Content

[0007] The utility model aims to provide an antifreeze structure for drain pipes in air-conditioning rooms, which has a simple structure and effectively utilizes the constant temperature characteristic of tobacco aging air-conditioning rooms. A heating block serving as a heating heat source in the air-conditioning room is arranged on the outside of the drain pipe, which heats the room and the drain pipe at the same time, effectively preventing the drain pipe from freezing. In addition, an annular pipe connected to the inside of the room is arranged on the outside of the drain pipe, so that the air inside the room can effectively exchange heat with the drain pipe, further ensuring the antifreeze ability of the drain pipe. The utility model has low use cost and good antifreeze effect.

The drain pipe 1 is generally arranged horizontally, and the end close to the outer side of the wall 4 can also be slightly lower to allow the air-conditioning water to flow out.

[0028] It should be noted that a constant temperature and humidity needs to be maintained inside the machine room. In winter weather, there must be a heat source object. In the present utility model, one of the heat source objects is the heating block 3. This heating block 3 is arranged on the outer wall of the drain pipe 1 located on the inner side of the wall 4.
