Abstract
Description
Technical Field
[0001] This application relates to the field of high-temperature water discharge technology in cigarette manufacturing, and in particular to a high-temperature water discharge device and tobacco leaf heating and humidification equipment for a cigarette manufacturing production line. Background Technology
[0002] In the process flow of cigarette manufacturing production line, saturated steam is usually used to heat and humidify the tobacco leaves. During this process, high-temperature water with a temperature higher than 60°C is generated. The temperature of this high-temperature water is significantly higher than the ambient temperature and needs to be discharged in a timely manner.
[0003] In traditional processes, this high-temperature water is typically discharged directly into the workshop's floor drain system through drainage pipes. The design aims to simplify the drainage path and utilize the natural flow of the floor drains for rapid drainage. However, since the underground pipe network in silk-making workshops generally uses ambient temperature tap water or circulating cooling water as the basic flow medium, the contact between the high-temperature water and the ambient temperature water (typically 15-30°C) in the floor drains instantly generates a large amount of visible steam. The continuous generation of steam not only causes fog to permeate the workshop floor area, reducing visibility and operational safety, but more importantly, a large amount of steam diffuses into the silk-making area, interfering with the normal temperature and humidity control of the production equipment. Utility Model Content
[0004] Therefore, it is necessary to provide a high-temperature water discharge device and tobacco leaf heating and humidification equipment for a cigarette processing production line that can solve the above problems.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] A high-temperature water discharge device for a cigarette manufacturing production line is used to discharge high-temperature water to a floor drain. The high-temperature water discharge device for the cigarette manufacturing production line includes:
[0007] The enclosure is equipped with a first interface and a second interface. The first interface is used to connect to a high-temperature water discharge pipe.
[0008] A connecting pipe, one end of which passes through the box and is connected to the first interface, and the other end of which is used to extend into the floor drain;
[0009] A cooling pipe is sleeved on the connecting pipe and has a connecting section, a cooling section, and a discharge section. One end of the connecting section is connected to a second interface. The cooling section is located between the connecting section and the discharge section, and both ends of the cooling section are connected to the connecting section and the discharge section, respectively. The end of the discharge section away from the cooling section is set as an outlet end and is used to connect to the floor drain. The cooling section is bent to form an opening, and the opening is away from the outlet end.
[0010] In the vertical direction, the second interface is positioned higher than the connection point between the discharge section and the cooling section. The inner diameter of the cooling section is larger than the outer diameter of the connecting pipe, so that a gap is formed between the inner wall of the cooling section and the outer wall of the connecting pipe, and the cooling medium is sealed in the gap.
[0011] Understandably, this application, by setting up a connecting pipe and a cooling pipe with a cooling section, allows the cooling medium to be sealed in the cooling section of the cooling pipe when high-temperature water is discharged. The high-temperature water flows into the connecting pipe through the first interface and is discharged to the floor drain along the connecting pipe. During this process, the high-temperature water exchanges heat with the cooling medium in the cooling pipe, which can reduce the temperature of the high-temperature water and reduce the amount of visible steam generated at the moment of contact between the high-temperature water and the room-temperature water in the floor drain. This avoids causing fog to spread in the workshop floor area, improves the visibility of the working environment and operational safety, and prevents steam from interfering with the normal temperature and humidity control of the production equipment.
[0012] In one embodiment, the outer diameter of the connecting pipe is R1, and the inner diameter of the cooling section is R2, where R2 ≥ 3R1.
[0013] In one embodiment, the length of the cooling pipe is d, and the length of the cooling section is a, where d > a ≥ 1 / 2d.
[0014] In one embodiment, the high-temperature water discharge device of the cigarette manufacturing production line further includes a sealing cover, which is sealed to the outlet end of the cooling pipe and is placed over the floor drain.
[0015] In one embodiment, the cooling section is configured as a U-shaped bend.
[0016] In one embodiment, a support is installed inside the cooling pipe, and the connecting pipe passes through the support and abuts against the support.
[0017] In one embodiment, the first interface is provided in multiple ways, and the housing is provided with an adapter and multiple adapter pipes, each of the adapter pipes being connected to one of the first interfaces; the adapter connects the connecting pipe and the multiple adapter pipes.
[0018] In one embodiment, the adapter pipe is welded to the housing;
[0019] And / or, the cooling pipe is welded to the housing.
[0020] In one embodiment, the high-temperature water discharge device of the cigarette manufacturing production line also includes a support rod;
[0021] One end of the support rod is connected to the box body, and the other end is used to support it in a preset position.
[0022] This application also provides the following technical solutions:
[0023] A tobacco leaf heating and humidification device includes a high-temperature water discharge pipe and a high-temperature water discharge device for a cigarette processing production line as described in any of the above embodiments.
[0024] Compared with existing technologies, the high-temperature water discharge device of the cigarette manufacturing production line is equipped with a connecting pipe and a cooling pipe with a cooling section. When high-temperature water is discharged, the cooling medium is sealed in the cooling section of the cooling pipe. The high-temperature water flows into the connecting pipe through the first interface and is discharged to the floor drain along the connecting pipe. During this process, the high-temperature water exchanges heat with the cooling medium in the cooling pipe, which can reduce the temperature of the high-temperature water and reduce the amount of visible steam generated when the high-temperature water comes into contact with the room temperature water in the floor drain. This avoids fogging in the workshop floor area, improves the visibility of the working environment and operational safety, and prevents steam from interfering with the normal temperature and humidity control of the production equipment.

[0037] Please see Figures 1 to 4This application provides a high-temperature water discharge device 100 for a cigarette processing production line, used to discharge high-temperature water generated in the tobacco leaf heating and humidification process to a floor drain (not shown). It should be explained that, here, high-temperature water refers to water with a temperature higher than 60°C generated in the tobacco leaf heating and humidification process.
[0038] Specifically, the high-temperature water discharge device 100 of the cigarette manufacturing production line includes a housing 10, a connecting pipe 20, and a cooling pipe 30. The housing 10 is provided with a first interface 11 and a second interface 12. The first interface 11 is used to connect to the high-temperature water discharge pipe. One end of the connecting pipe 20 passes through the housing 10 and is connected to the first interface 11, while the other end is used to extend into a floor drain. The cooling pipe 30 is sleeved on the connecting pipe 20 and has a connecting section 31, a cooling section 32, and a discharge section 33. One end of the connecting section 31 is connected to the second interface 12, and the cooling section 32 is located between the connecting section 31 and the discharge section 33. Between the discharge section 33, and the two ends of the cooling section 32 are respectively connected to the connecting section 31 and the discharge section 33. The end of the discharge section 33 away from the cooling section 32 is set as the outlet end and is used to connect to the floor drain. The cooling section 32 is bent to form an opening 321, which is away from the outlet end. In the vertical direction, the position of the second interface 12 is higher than the position of the connection between the discharge section 33 and the cooling section 32. The inner diameter of the cooling section 32 is larger than the outer diameter of the connecting pipe 20, so that a gap 34 is formed between the inner wall of the cooling section 32 and the outer wall of the connecting pipe 20. The cooling medium is sealed in the gap 34. Thus, by setting up a connecting pipe 20 and a cooling pipe 30 with a cooling section 32, when high-temperature water is discharged, the cooling medium is sealed in the cooling section 32 of the cooling pipe 30. The high-temperature water flows into the connecting pipe 20 through the first interface 11 and is discharged to the floor drain along the connecting pipe 20. During this process, the high-temperature water exchanges heat with the cooling medium in the cooling pipe 30, which can reduce the temperature of the high-temperature water and reduce the amount of visible steam generated at the moment of contact between the high-temperature water and the room temperature water in the floor drain. This avoids causing fog to spread in the workshop floor area, improves the visibility of the working environment and the safety of operation, and can prevent steam from interfering with the normal temperature and humidity control of the production equipment.
[0039] In one embodiment, such as Figures 1 to 4 As shown, multiple first interfaces 11 are provided. The housing 10 contains adapters 111 and multiple adapter pipes 112, with each adapter pipe 112 corresponding to one first interface 11. The adapters 111 connect the connecting pipe 20 and the multiple adapter pipes 112. It should be explained that the number of adapter interfaces on the adapter 111 is equal to the sum of the number of adapter pipes 112 and the number of connecting pipes 20. For example, if there are two first interfaces 11, two adapter pipes 112, and one connecting pipe 20, then the adapter 111 has three adapter interfaces.
[0040] Here, the number of first interfaces 11 can be two, three, four, five, etc. The number of adapter pipes 112 is the same as that of the first interfaces 11, and will not be described in detail here. Here, by setting different numbers of first interfaces 11 on the housing 10, multiple high-temperature water discharge pipes can be connected to adapt to the needs of different tobacco heating and humidification processes.
[0041] Furthermore, since both the adapter pipe 112 and the adapter 111 need to come into contact with high-temperature water, high-temperature resistant materials such as stainless steel and polytetrafluoroethylene are required.
[0042] In this embodiment, three first interfaces 11 and three adapter pipes 112 are configured, with the three first interfaces 11 corresponding to three high-temperature water discharge pipes. The adapter pipes 112 and adapters 111 are respectively made of stainless steel internal thread connectors and stainless steel cross internal thread connectors. In this way, the manufacturing cost of the high-temperature water discharge device 100 in the cigarette manufacturing production line can be reduced while meeting the requirements for high-temperature resistance.
[0043] In one embodiment, the adapter pipe 112 is welded to the housing 10; and / or, the cooling pipe 30 is welded to the housing 10. Thus, by using welding, the welded connection forms a single unit, capable of withstanding the pressure and impact of high-temperature water, ensuring the stability of the adapter pipe 112 and the housing 10, and the cooling pipe 30 and the housing 10, during long-term operation.
[0044] In this embodiment, the transfer pipe 112 and the housing 10, as well as the cooling pipe 30 and the housing 10, are connected by welding. This makes the high-temperature water discharge device 100 of the entire cigarette manufacturing production line more stable, thereby improving the reliability of the device.
[0045] In one embodiment, the connecting pipe 20 needs to be in contact with high-temperature water, so it needs to be made of a high-temperature resistant material, such as stainless steel, polytetrafluoroethylene, fluororubber, silicone rubber, etc.
[0046] like Figure 3 As shown, the outer diameter of the connecting pipe 20 is R1, and the inner diameter of the cooling section 32 is R2, where R2 ≥ 3R1. Here, the relationship between R2 and R1 can be R2 = 3R1, R2 = 4R1, R2 = 5R1, etc. By setting R2 ≥ 3R1, the content of cooling medium in the cooling section 32 can be guaranteed, thereby ensuring that there is sufficient cooling medium in the cooling section 32 for heat exchange with the high-temperature water in the connecting pipe 20.
[0047] Please refer to Figure 1 The cooling pipe 30 is integrally formed to improve its structural strength. In this embodiment, the cooling pipe 30 is made of stainless steel.
[0048] In one embodiment, the length of the cooling pipe 30 is d, and the length of the cooling section 32 is a, where d > a ≥ 1 / 2d. Here, the relationship between a and d can be a = 1 / 2d, a = 2 / 3d, a = 5 / 6d, etc. By setting d > a ≥ 1 / 2d, the contact area between the connecting pipe 20 and the cooling medium in the cooling section 32 can be guaranteed, thereby ensuring that the high-temperature water in the connecting pipe 20 can fully exchange heat with the cooling medium, thus effectively reducing the temperature of the water discharged to the floor drain.
[0049] In one embodiment, the cooling section 32 is configured as a U-shaped bend 322. However, it is not limited to this; the cooling section 32 can also be configured in various shapes such as wavy, S-shaped, or V-shaped. But the two ends of the cooling section 32 should be higher than the height of other parts of the cooling section 32 to ensure that the cooling medium can be well contained within the cooling section 32.
[0050] In this embodiment, water is generally chosen as the cooling medium.
[0051] like Figures 1 to 4 As shown, the high-temperature water discharge device 100 of the cigarette processing production line also includes a sealing cover 40, which is sealed to the outlet end of the cooling pipe 30 and is placed over the floor drain. Thus, through the sealed connection between the sealing cover 40 and the outlet end of the cooling pipe 30, when the cooled water is discharged into the floor drain, a small amount of steam generated enters the cooling section 32 through the outlet end, and liquefies back into water after contacting the cooling medium. Therefore, the installation of the cooling section 32 and the sealing cover 40 further prevents water vapor from overflowing from the floor drain, avoiding the formation of fog on the workshop floor.
[0052] In one embodiment, a support member 35 is installed inside the cooling pipe 30, and the connecting pipe 20 passes through the support member 35 and abuts against it. By providing the support member 35, the cooling pipe 30 can be supported and limited to ensure that the connecting pipe 20 does not come into contact with the cooling pipe 30, thus ensuring the contact area between the connecting pipe 20 and the cooling medium. Here, the support member 35 can be configured as a support ring, support platform, or other structures.
[0053] Preferably, the support member 35 is configured as a support ring. By configuring the support member 35 as a support ring, the connecting pipe 20 can be located in the middle of the cooling pipe 30, thereby improving the heat exchange efficiency between the high-temperature water in the connecting pipe 20 and the cooling medium in the cooling pipe 30.
[0054] In one embodiment, the high-temperature water discharge device 100 of the cigarette manufacturing production line further includes a support rod 50; one end of the support rod 50 is connected to the housing 10, and the other end is used to support it at a preset position. Here, the preset position can be the ground or a mounting bracket, etc.
[0055] Preferably, one end of the support rod 50 is welded to the housing 10, and the other end can be fixed in a preset position by screws or the like.
[0056] This application also provides the following technical solutions:
[0057] A tobacco leaf heating and humidification device includes a high-temperature water discharge pipe and a high-temperature water discharge device 100 for a cigarette processing production line as described in any of the above embodiments.
[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0059] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
