Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a split-type flexible connection of a hot air pipeline for an air-flow tobacco dryer. Background Art

[0002] The HDT air-flow tobacco dryer is an important equipment in tobacco processing. There is a flexible connection of a process air pipeline between the outlet of a heat exchange furnace and the inlet of a process gas pipeline, which is used to transport the heated process gas in the heat exchange furnace to the process gas pipeline. In actual production, the flexible connection of the process air pipeline of the tobacco dryer is prone to breakage after being used for a certain period of time, resulting in the leakage of process gas, and it is not easy to detect after the leakage, thus having an adverse impact on the quality of cut tobacco processing. The existing integral flexible connection is large in volume and high in price. If the integral flexible connection is replaced, there will be disadvantages such as difficult replacement and high cost. Summary of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a split-type flexible connection of a hot air pipeline for an air-flow tobacco dryer, so as to solve the problems of difficult replacement, high cost, etc. by means of split and spliced flexible connection, and can detect the leakage of process gas.

[0004] The technical solution adopted by the utility model to solve its problems is as follows:

[0005] A split-type flexible connection of a hot air pipeline for an air-flow tobacco dryer includes: spliced hoses. There are two spliced hoses, and one end of one spliced hose is connected to one end of the other spliced hose; a protective cover, which is sleeved on the spliced hoses, and the protective cover is connected to the spliced hoses through connectors, and a mist detector is arranged on the protective cover.

[0006] Through the above scheme, the design of two spliced hoses allows for easy replacement or adjustment of a certain part when needed without affecting the entire system, increasing the convenience of maintenance. At the same time, such a design is also convenient for installation and disassembly, especially in the case of limited space. The protective cover can also play a certain role in safety isolation to prevent the spliced hoses from overheating and causing scalding to personnel. The mist detector is used to detect the leaked process gas.

[0007] Further, one end of the spliced hose is provided with an interface flange, and the other end is provided with a splicing ring. The splicing ring on one spliced hose is connected to the splicing ring on the other spliced hose.

[0008] Through the above further scheme, the splicing ring can enhance the connection strength between the spliced hoses, ensure the tight fit between the two, and avoid leakage caused by loose connection. The splicing ring enables a flexible connection between the two spliced hoses.

[0009] Furthermore, the interface flange is connected to the pipeline.

[0010] Through the above further solution, flange connection is a very strong connection method. It tightly fixes two flange surfaces together through bolts, thus forming a stable joint. This design can withstand relatively high pressures and temperature changes, ensuring that the connection part will not loosen or be damaged easily.

[0011] Furthermore, it also includes a sealing gasket. A sealing gasket is provided at the middle where the two splicing rings are connected.

[0012] Through the above further solution, the main function of the sealing gasket is to fill the tiny gaps between the two splicing rings, thus forming a continuous and leak-free sealing surface. This is crucial for preventing hot air, moisture or other media from leaking through the connection, ensuring the overall efficiency of the system. The sealing gasket can absorb and relieve mechanical stress caused by temperature changes or internal pressure fluctuations to a certain extent, maintaining the stability and tightness of the connection part.

[0013] Furthermore, the connecting piece is T-shaped. The connecting piece includes a first connecting piece and a second connecting piece. The first connecting piece is connected to the splicing ring, and the second connecting piece is connected to the protective cover. The second connecting piece is arc-shaped and is in contact with the protective cover.

[0014] Through the above further solution, the connecting piece can provide a support point for the protective cover, avoiding the protective cover from leaning against the splicing hose, preventing the protective cover from overheating, and further preventing personnel from touching the high-temperature splicing hose and getting scalded.

[0015] Furthermore, the mist detector is connected to the controller through a signal transmission line, and the controller is connected to the alarm lamp through a signal transmission line.

[0016] Through the above further solution, when the mist detector detects the leaked process gas, it sends a signal to the controller, and the controller controls the alarm lamp to give an alarm, reminding the operator to take measures.

[0017] Furthermore, a number of leakage holes are provided on the protective cover.

[0018] Through the above further solution, the leakage holes allow the heat inside the hot air pipeline to dissipate through these pores, which helps to reduce the temperature difference between the inside and outside of the protective cover.

[0019] In summary, a split-type hot air pipeline soft connection of a spliced air current cut tobacco drying machine provided by the present utility model has the following technical effects: The spliced splicing hose can be disassembled and assembled separately, which is convenient for maintenance and repair. Installing a protective cover can help prevent personnel from touching the high-temperature pipeline and getting scalded. Installing a mist detector can detect in real time whether there is process gas leaking from the splicing hose. Brief Description of the Drawings
