Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a liquor conveying pipeline. Background Technology

[0002] Baijiu is a liquid mixture with ethanol as its main component and containing a variety of flavor substances (such as esters, alcohols, acids, etc.). Baijiu conveying pipelines are key facilities used to transport base liquor, finished liquor and other related liquids in the production, storage and bottling of baijiu.

[0003] In the early days, ordinary carbon steel pipes were mostly used, but they were prone to rust. Rust would mix into the liquor, causing it to become cloudy and produce an off-flavor. Furthermore, the inner walls of the corroded pipes were rough, making them prone to the growth of bacteria and residual impurities. In some cases, plastic pipes (such as ordinary PVC) were used, but plasticizers and stabilizers in the plastics could migrate into the liquor, contaminating it and affecting food safety.

[0004] With the advancement of large-scale and standardized production in the liquor industry, the technical requirements for conveying pipelines are constantly increasing. Food-grade stainless steel (such as 304 and 316 stainless steel) has become the mainstream material. It has the characteristics of corrosion resistance, strong chemical stability, smooth inner wall, and easy cleaning. It meets food hygiene standards and can effectively protect the flavor and quality of liquor. Some high-end scenarios use seamless stainless steel pipes to further reduce pipe joints and reduce the risk of leakage and pollution.

[0005] However, in cold regions or during winter, the use of food-grade stainless steel pipes to transport baijiu (Chinese liquor) makes them susceptible to environmental influences. The baijiu inside the food-grade stainless steel pipes may experience decreased fluidity or localized solidification due to low temperatures, forming "ice blockages." This can lead to an abnormal increase in pressure inside the pipes, potentially causing pipe joints to burst and resulting in liquor leakage. Utility Model Content

[0006] The purpose of this utility model is to provide a liquor conveying pipeline, which aims to solve the problem that when existing liquor conveying pipelines are used in cold regions, the local solidification at low temperatures causes the pressure inside the pipeline to rise, resulting in the pipe joints breaking and causing liquor leakage.

[0007] To achieve the above objectives, this utility model provides a liquor conveying pipeline, including a pipeline body and a thermostatic sleeve. The thermostatic sleeve includes a hollow sleeve, a diverter pipe, an electrically controlled valve, a temperature detector, and an insulation layer. The hollow sleeve is fitted outside the pipeline body, and the insulation layer is fitted outside the hollow sleeve. The diverter pipe communicates with the hollow sleeve and penetrates the insulation layer. The electrically controlled valve is mounted on the diverter pipe, and the temperature detector is mounted on the hollow sleeve and penetrates the insulation layer.

[0008] The diverter includes a diverter body and a connector. The connector communicates with the cavity sleeve and is located on the outer wall of the cavity sleeve. The diverter body is fixedly connected to the connector and is located on the side of the connector away from the cavity sleeve.

[0009] The liquor conveying pipeline also includes quick-release flanges, which are assembled on both sides of the pipeline body.

[0010] The quick-release flange includes a connecting flange, a snap-fit ​​flange, and a sealing ring. The connecting flange is fixedly connected to the pipe body and is located on one side of the pipe body. The snap-fit ​​flange is fixedly connected to the pipe body and is located on the side of the pipe body away from the connecting flange. The sealing ring is fitted on the outside of the snap-fit ​​flange.

[0011] The connecting flange includes a flange body, rotating jaws, and a fixing bolt. The flange body is fixedly connected to the pipe body and is located on one side of the pipe body. The rotating jaws are assembled around the flange body. The fixing bolts are threadedly connected to the rotating jaws and pass through the rotating jaws.

[0012] This utility model discloses a liquor conveying pipeline. When using the pipeline body to transport liquor in cold regions, the worker first opens the electrically controlled valve via a controller, introducing hot water into the hollow sleeve through the diversion pipe (connected to an external hot water source). The hot water quickly fills the hollow sleeve, and then conducts heat to the pipeline body based on the principle of heat conduction, thus preheating the pipeline body. The detection end of the temperature detector is located inside the pipeline body, monitoring the temperature of the pipeline body in real time. When the temperature detector detects that the pipeline body has reached a preset value, the electrically controlled valve is closed, and the discharge port at the bottom of the hollow sleeve (not shown in the figure) is opened to discharge the hot water. After closing the discharge port, liquor can be introduced into the preheated pipe body to achieve liquor transportation. The insulation layer is used to insulate the pipe body and prevent the preheated pipe body from losing heat quickly. During the transportation of liquor, the temperature detector monitors the temperature inside the pipe body in real time. When the temperature shows a downward trend, hot water is repeatedly introduced into the cavity sleeve to maintain the temperature of the cavity sleeve, thereby ensuring the temperature of the pipe body and the temperature of the transported liquor. This solves the problem that existing liquor transportation pipes, when used in cold regions, will experience local solidification at low temperatures, leading to increased pressure inside the pipe, causing pipe joints to burst and resulting in liquor leakage.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 3 This utility model provides a liquor conveying pipeline, including a pipeline body 1 and a thermostatic sleeve 2. The thermostatic sleeve 2 includes a hollow sleeve 21, a diversion pipe 22, an electrically controlled valve 23, a temperature detector 24, and a heat insulation layer 25. The hollow sleeve 21 is sleeved on the outside of the pipeline body 1, and the heat insulation layer 25 is sleeved on the outside of the hollow sleeve 21. The diversion pipe 22 communicates with the hollow sleeve 21 and penetrates the heat insulation layer 25. The electrically controlled valve 23 is mounted on the diversion pipe 22, and the temperature detector 24 is mounted on the hollow sleeve 21 and penetrates the heat insulation layer 25.

[0020] In this embodiment, when transporting liquor using the pipeline body 1 in cold regions, the worker first opens the electrically controlled valve 23 via the controller, introducing hot water into the hollow sleeve 21 through the diversion pipe 22 (connected to an external hot water source). The hot water quickly fills the hollow sleeve 21, and at this time, the hot water conducts heat to the pipeline body 1 based on the principle of heat conduction, thereby preheating the pipeline body 1. The detection end of the temperature detector 24 is located inside the pipeline body 1, monitoring the temperature of the pipeline body 1 in real time. When the temperature detector 24 detects that the pipeline body 1 has reached a preset value, the electrically controlled valve 23 is closed, and the discharge port at the bottom of the hollow sleeve 21 (not shown in the figure) is opened to release the hot water. After discharging and closing the discharge port, liquor can be introduced into the preheated pipe body 1 to achieve liquor transportation. The insulation layer 25 is used to insulate the pipe body 1 and prevent the heat of the preheated pipe body 1 from dissipating quickly. During the transportation of liquor, the temperature detector 24 monitors the temperature inside the pipe body 1 in real time. When the temperature shows a downward trend, hot water is repeatedly introduced into the cavity sleeve 21 to maintain the temperature of the cavity sleeve 21, thereby ensuring the temperature of the pipe body 1 and the temperature of the transported liquor. This solves the problem that when existing liquor transportation pipelines are used in cold regions, local solidification at low temperatures can cause the pressure inside the pipeline to rise, resulting in the pipe joints breaking and causing liquor leakage.

[0021] Furthermore, the diversion pipe 22 includes a diversion pipe body 221 and a connector 222. The connector 222 communicates with the cavity sleeve 21 and is located on the outer wall of the cavity sleeve 21. The diversion pipe body 221 is fixedly connected to the connector 222 and is located on the side of the connector 222 away from the cavity sleeve 21.

[0022] In this embodiment, the connector 222 is provided to facilitate the connection between the diversion pipe body 221 and the cavity sleeve 21. The diversion pipe body 221 is evenly distributed above the cavity sleeve 21, which can evenly introduce hot water into the cavity sleeve 21, making the preheating of the cavity sleeve 21 more uniform.

[0023] Furthermore, the liquor conveying pipeline also includes a quick-release flange 3, which is assembled on both sides of the pipeline body 1.

[0024] In this embodiment, the quick-release flange 3 is used to connect multiple pipe bodies 1.

[0025] Furthermore, the quick-release flange 3 includes a connecting flange 31, a snap-fit ​​flange 32, and a sealing ring 33. The connecting flange 31 is fixedly connected to the pipe body 1 and is located on one side of the pipe body 1. The snap-fit ​​flange 32 is fixedly connected to the pipe body 1 and is located on the side of the pipe body 1 away from the connecting flange 31. The sealing ring 33 is sleeved on the outside of the snap-fit ​​flange 32.

[0026] In this embodiment, the snap-fit ​​flange 32 is inserted into the connecting flange 31 to snap-fit, thereby connecting the two pipe bodies 1. The sealing ring 33 is used to enhance the airtightness between the connecting flange 31 and the snap-fit ​​flange 32, and to prevent the leakage of liquor at the connection of the pipe bodies 1.

[0027] Furthermore, the connecting flange 31 includes a flange body 321, a rotating claw 322, and a fixing bolt 333. The flange body 321 is fixedly connected to the pipe body 1 and is located on one side of the pipe body 1. The rotating claw 322 is assembled around the flange body 321. The fixing bolt 333 is threadedly connected to the rotating claw 322 and passes through the rotating claw 322.

[0028] In this embodiment, after the snap-fit ​​flange 32 is inserted into the flange body 321, the worker rotates the rotating claw 322 to the tail of the snap-fit ​​flange 32, and then rotates the fixing bolt 333 so that the fixing bolt 333 abuts against the snap-fit ​​flange 32, thereby realizing the connection between the snap-fit ​​flange 32 and the flange body 321.

[0029] The above-disclosed embodiments are merely preferred embodiments of a liquor conveying pipeline of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
