[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] See also Figure 1As shown, according to one aspect of an embodiment of the present application, a connection structure is provided for connecting a wire drying machine with a rotary joint, the connection structure comprising a shell 1 and a condensate collecting pipe 4, a partition 2 is arranged in the shell 1, one side of the partition 2 is a condensate recovery chamber 11 connected to the condensate outlet of the wire drying machine, and the other side is a steam outlet chamber 12 connected to the steam inlet of the wire drying machine, a condensate drainage pipe 3 is arranged on the side of the partition 2 away from the condensate recovery chamber 11, and a through hole is opened at the center of the partition 2, so that the condensate drainage pipe 3 is connected to the condensate recovery chamber 11 through the through hole, and the condensate drainage pipe 3 is also connected to the condensate collecting pipe 4, and the condensate collecting pipe 4 is arranged on the downstream side of the condensate drainage pipe 3 along the flow direction; wherein, a groove is opened on the surface of the condensate drainage pipe 3 that contacts the condensate collecting pipe 4, and an elastic pad is arranged in the groove to form a sealing structure 5.

[0025] The connection structure provided in the embodiment of the present application can form a sealing structure 5 by opening a groove on the surface of the condensate drainage pipe 3 that contacts the condensate collection pipe 4, and arranging an elastic pad in the groove, so that the condensate drainage pipe 3 and the condensate collection pipe 4 can be dynamically sealed to prevent steam from entering the condensate collection pipe 4 and affecting production indicators; at the same time, the sealing structure 5 is lubricated by steam and condensate during use, which can reduce the wear of the elastic pad, extend the service life of the sealing structure 5, and improve the sealing effect.

[0026] Among them, after the distributor is connected to the tobacco drying machine through the connection structure, it can supply steam to the tobacco drying machine and recover condensed water. It can be understood that when steam is supplied to the tobacco drying machine, the steam carries a large amount of heat, which is transferred to the tobacco by heat exchange, so that the water in the tobacco evaporates and the purpose of drying is achieved; when the condensed water is recovered, on the one hand, the condensed water can be prevented from accumulating inside the tobacco drying machine, avoiding corrosion and damage to the equipment and extending the service life of the equipment, and on the other hand, the condensed water can be recovered for secondary use.

[0027] Specifically, one end of the connection structure is fixedly arranged on the wire drying machine, and the other end is connected to the distributor through a rotary joint.

[0028] The connection structure includes a shell 1, and the shell 1 may be cylindrical, etc., which is not further limited in this embodiment.

[0029] Among them, a condensate recovery chamber 11 and a steam outlet chamber 12 are provided in the shell 1. The condensate recovery chamber 11 is used to receive the condensate of the wire drying machine and discharge the condensate into the condensate interface of the distributor; the steam outlet chamber 12 is used to receive the steam delivered by the distributor and discharge the steam into the wire drying machine.

[0030] Specifically, a partition 2 is provided in the shell 1, and the partition 2 is provided perpendicular to the central axis of the shell 1, so as to form a condensate recovery chamber 11 and a steam outlet chamber 12 on both sides of the partition 2, respectively. In the embodiment of the present application, the condensate recovery chamber 11 is provided away from the distributor, and the steam outlet chamber 12 is provided close to the distributor. It can be understood that the condensate recovery chamber 11 is provided away from the distributor, which can extend the time for the condensate to flow into the distributor, help to fully cool and stabilize the temperature, and reduce temperature fluctuations in subsequent processing; the steam outlet chamber 12 is provided close to the distributor, which can shorten the time for the steam to be discharged into the tobacco drying machine, ensure that the steam has a higher temperature, carries more heat, and improves the quality of the tobacco.

[0031] Among them, the partition 2 can be annular, and a condensate drainage pipe 3 is provided on the side of the partition 2 facing away from the condensate recovery chamber 11, that is, the side of the partition 2 close to the distributor. The condensate drainage pipe 3 is relatively fixed to the partition 2, and the condensate drainage pipe 3 is connected to the condensate recovery chamber 11 through the central hole of the annular partition 2, so that the condensate discharged by the silk drying machine received in the condensate recovery chamber 11 can flow to the distributor.

[0032] The downstream side of the condensate drainage pipe 3 along the flow path direction is provided with a condensate collection pipe 4, one end of the condensate collection pipe 4 is connected to the condensate drainage pipe 3, and the other end is connected to the condensate interface of the distributor. It should be noted that the flow path direction is the flow direction of the condensate.

[0033] Specifically, in the embodiment of the present application, the condensed water in the wire drying machine first enters the condensed water recovery chamber 11, then enters the condensed water collecting pipe 4 through the condensed water drainage pipe 3 connected to the condensed water recovery chamber 11, and finally flows into the distributor through the condensed water collecting pipe 4; the steam discharged from the distributor first enters the steam outlet chamber 12, and then enters the wire drying machine through the steam outlet chamber 12.

[0034] The condensate collecting pipe 4 may be a seamless steel pipe.

[0035] Among them, a sealing structure 5 is provided at the junction of the condensate collecting pipe 4 and the condensate drainage pipe 3 to prevent condensate from leaking at the junction of the condensate collecting pipe 4 and the condensate drainage pipe 3, or steam from entering the condensate collecting pipe 4 from the junction of the condensate collecting pipe 4 and the condensate drainage pipe 3.

[0036] The condensate drainage pipe 3 can rotate relative to the condensate collection pipe 4, so that the sealing structure 5 is a dynamic seal.

[0037] Specifically, as one embodiment, the diameter of the condensate drainage tube 3 is larger than the diameter of the condensate collection tube 4, and at least a portion of the condensate collection tube 4 is inserted into the condensate drainage tube 3. At this time, a groove is opened on the inner wall of the condensate drainage tube 3 at a position relative to the condensate collection tube 4, and an elastic pad is arranged in the groove to form a sealing structure 5, so that the condensate drainage tube 3 and the condensate collection tube 4 are dynamically sealed; as another embodiment, the diameter of the condensate drainage tube 3 is smaller than the diameter of the condensate collection tube 4, and at least a portion of the condensate drainage tube 3 is inserted into the condensate collection tube 4. At this time, a groove is opened on the outer wall of the condensate drainage tube 3 at a position relative to the condensate collection tube 4, and an elastic pad is arranged in the groove to form a sealing structure 5, so that the condensate drainage tube 3 and the condensate collection tube 4 are dynamically sealed.

[0038] The groove may be an annular groove, and the elastic pad may be an O-ring.

[0039] Specifically, the flowing medium in the condensate drainage pipe 3 and the condensate collection pipe 4 is condensate, and the flowing medium outside the condensate drainage pipe 3 and the condensate collection pipe 4 is steam. It can be understood that both condensate and steam can lubricate the sealing structure 5, thereby reducing the wear of the elastic pad, extending the service life of the sealing structure 5, and improving the sealing effect.

[0040] In some possible implementations provided in this application, see Figure 1 As shown, the connection structure further includes a guide plate 6, which is disposed in the steam outlet cavity 12, and has a plurality of holes formed on the guide plate 6 for the steam to pass through.

[0041] The guide plate 6 is provided with a plurality of holes, that is, the guide plate 6 may be a porous plate.

[0042] Specifically, a condensate collecting pipe 4 passes through the steam outlet chamber 12, and the guide plate 6 is specifically an annular porous plate.

[0043] Among them, several holes on the guide plate 6 are used to pass steam, so that the steam can be evenly dispersed in all directions, thereby ensuring that the subsequent tobacco drying machine can obtain a balanced steam supply and improve the consistency and quality of the tobacco. In addition, it should be noted that the guide plate 6 can also be used to support the condensate collection pipe 4 to reduce the vibration of the condensate collection pipe 4.

[0044] In some possible implementations provided in this application, see Figure 1 As shown, the condensate collecting pipe 4 extends in the axial direction of the condensate collecting pipe 4 in a direction away from the condensate draining pipe 3 .

[0045] The condensed water collecting pipe 4 extends along the flow path direction.

[0046] Specifically, the condensate collection pipe 4 extends out of the housing 1 and extends along the flow path. It should be noted that when the condensate collection pipe 4 extends out of the housing 1 and extends along the flow path, the condensate collection pipe 4 has a certain length, which can increase the residence time of the condensate, help to fully cool and stabilize the temperature, and reduce temperature fluctuations in subsequent processing; on the other hand, it can improve the collection efficiency and accommodate more condensate; on the other hand, it can transmit pressure fluctuations and reduce the impact of pressure fluctuations inside the distributor on the condensate collection process.

[0047] In some possible implementations provided in this application, see Figure 1 As shown, the connection structure also includes a condensate recovery pipe 7, one end of which is connected to the condensate outlet of the wire drying machine, and the other end is connected to the condensate recovery chamber 11. By providing the condensate recovery pipe 7, a discharge channel is provided for the condensate in the wire drying machine, which is convenient for collecting the condensate and preventing the condensate from accumulating inside the wire drying machine.

[0048] In the above embodiments, see Figure 1 As shown, at least six condensate recovery pipes 7 are provided, and at least six condensate recovery holes connected to the condensate recovery chamber 11 are opened on the shell 1 along the circumferential direction of the shell 1, and the at least six condensate recovery holes are arranged one-to-one with the at least six condensate recovery pipes 7.

[0049] Among them, at least six drying areas are arranged inside the silk drying machine, which can heat at least six copying plates at the same time.

[0050] Among them, at least six condensed water recovery pipes 7 are arranged in one-to-one correspondence with at least six drying areas. For example, when six drying areas are arranged, all six drying areas are connected to the condensed water recovery pipe 7, that is, six condensed water recovery pipes 7 are arranged.

[0051] Specifically, six condensate recovery holes are provided on the shell 1, and the six condensate recovery holes are evenly arranged along the circumferential direction of the shell 1 and are connected to the condensate recovery chamber. In the embodiment of the present application, the six condensate recovery holes are arranged in a one-to-one correspondence with the six condensate recovery pipes 7, so that the condensate recovery chamber 11 can simultaneously receive the condensate discharged from the six drying areas.

[0052] In some possible implementations provided in this application, see Figure 1 As shown, the connection structure also includes a steam output pipe 8, one end of which is connected to the steam inlet of the tobacco drying machine, and the other end is connected to the steam outlet chamber 12. By providing the steam output pipe 8, a conveying channel is provided for conveying steam to the tobacco drying machine, ensuring that the steam can reach the designated position, providing energy support for tobacco production.

[0053] In the above embodiments, see Figure 1As shown, at least six steam output pipes 8 are provided, and at least six steam output holes connected to the steam outlet cavity 12 are opened on the shell 1 along the circumferential direction of the shell 1. The at least six steam output pipes 8 are arranged one by one with the at least six steam output pipes 8.

[0054] Among them, at least six drying areas are arranged inside the silk drying machine, which can heat at least six copying plates at the same time.

[0055] Among them, at least six steam output pipes 8 are arranged in one-to-one correspondence with at least six drying areas. For example, when six drying areas are arranged, all six drying areas are connected to the steam output pipe 8, that is, six steam output pipes 8 are arranged.

[0056] Specifically, six steam output holes are provided on the shell 1, and the six steam output holes are evenly arranged along the circumferential direction of the shell 1 and are connected to the steam outlet cavity 12. In the embodiment of the present application, the six steam output holes are arranged in a one-to-one correspondence with the six steam output pipes 8, so that steam can be supplied to six drying areas at the same time.

[0057] In some possible implementations provided in this application, see Figure 1 As shown, the connection structure further includes a fixing flange 9, which is arranged at one end of the housing 1 close to the wire drying machine, and is used to connect the wire drying machine so that the housing 1 and the wire drying machine are relatively fixed. By providing the fixing flange 9, the connection structure and the wire drying machine can be firmly connected together, ensuring the stability and sealing of the connection between the connection structure and the wire drying machine.

[0058] In some possible implementations provided in this application, see Figure 1 As shown, the connection structure also includes a rotating flange 10, which is arranged at one end of the shell 1 away from the wire drying machine. The rotating flange 10 is used to connect the rotating joint so that the rotating joint can rotate relative to the distributor to adapt to the rotation of the cylinder of the wire drying machine when it is running.

[0059] Another aspect of an embodiment of the present application provides a dispenser comprising any one of the above-mentioned connection structures.

[0060] The distributor may further include a rotary joint, which is connected to the rotary flange.
