Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf feeding steam heating, in particular to a nozzle. Background Art

[0002] Tobacco leaves are an indispensable raw material for the production of cigarettes. They not only determine the quality of cigarette products, but also greatly affect the production costs of tobacco companies. In the process of tobacco leaf processing and production, the feeding link is to increase the temperature and humidify the tobacco leaves and add sugar. At present, most tobacco leaf heating methods use direct injection pipelines to input steam for heating. The required pressure of pipeline steam is above 0.5MPa, and the steam flow rate is 40-60m / s. Therefore, when high-speed direct injection steam directly acts on tobacco leaves, this heating method will cause some tobacco leaves to be impacted into fragments, resulting in the fragmented tobacco leaves being screened out by the screen in subsequent processing, increasing the consumption of tobacco leaves, causing a large amount of waste of tobacco leaves, and thus increasing the production cost of tobacco leaf processing. Utility Model Content

[0003] The utility model aims to solve the problem that the existing heating method easily breaks tobacco leaves and increases tobacco leaf consumption. The utility model provides a nozzle that can reduce the impact force and flow rate of direct steam injection on tobacco leaves, thereby reducing tobacco leaf consumption and reducing the production cost of tobacco leaf processing.

[0007] A diffuser is detachably connected to the other end of the support portion, and the diffuser is spaced apart from the outlet end of the base along the fluid output direction;

[0008] The support portion is provided with a plurality of gaps at intervals along the circumferential direction. When the fluid is output to the diffuser through the channel, the diffuser can disperse the fluid so that the fluid is output through the plurality of gaps.

[0009] By adopting the above technical solution, the diffuser and the outlet end of the base are spaced apart in the fluid output direction, that is, a certain distance is set between the two, so that the diffuser can disperse the fluid output from the outlet end of the base. In addition, the support portion is also provided with a plurality of gaps along the circumferential direction so that the fluid dispersed by the diffuser can be buffered and sprayed onto the tobacco leaves more evenly, thereby solving the problems of high impact force and fast flow rate of the fluid on the tobacco leaves, reducing the crushing of the tobacco leaves, and reducing the production cost of tobacco leaf processing.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of the utility model provides a nozzle, comprising: a base 1, a diffuser 2 and a support portion 3.

[0028] Specifically, the substrate 1 has a channel for fluid to pass therethrough, and an inlet end 11 of the substrate 1 is provided with a connecting portion 13, which is connected to the fluid source 5;

[0029] The support portion 3 extends along the fluid output direction, and one end of the support portion 3 is connected to the outlet end 12 of the base body 1;

[0030] The diffuser 2 is detachably connected to the other end of the support portion 3, and the diffuser 2 is spaced apart from the outlet end 12 of the base 1 along the fluid output direction;

[0031] The support portion 3 is provided with a plurality of gaps 34 spaced apart along the circumferential direction. When the fluid is output to the diffuser 2 through the channel, the diffuser 2 can disperse the fluid so that the fluid is output through the plurality of gaps 34 .

[0032] The application fully considers the problems that may arise when workers heat tobacco leaves. By arranging the diffuser 2 and the outlet end 12 of the base 1 along the fluid output direction, that is, a certain distance is provided between the two, the diffuser 2 can disperse the fluid output from the outlet end 12 of the base 1. In addition, the support portion 3 is also provided with a plurality of gaps 34 along the circumferential direction, so that the fluid dispersed by the diffuser 2 can be evenly sprayed onto the tobacco leaves, thereby reducing the impact force of the fluid and making the fluid evenly dispersed.

[0033] Furthermore, the support portion 3 further comprises an adjusting mechanism 4, and the adjusting mechanism 4 can adjust the distance between the diffuser 2 and the outlet end 12 of the base body 1 along the fluid output direction.

[0034] Specifically, when the nozzle needs to be used, the diffuser 2 is first installed on the support 3, and then the distance between the diffuser 2 and the outlet end 12 of the base 1 along the fluid output direction is adjusted by the adjustment mechanism 4 and the diffuser 2 is fixed. Subsequently, the operator connects the connection portion 13 of the base 1 to the fluid source 5 to be used, and then starts the device to spray the tobacco leaves. When the diffuser 2 does not achieve the best dispersion effect on the fluid (that is, the impact force of the fluid is not effectively reduced or the scattering direction of the fluid does not meet the operator's expectations), the operator can use the adjustment mechanism 4 again to adjust the position of the diffuser 2 along the fluid output direction, so that the diffuser 2 disperses the fluid more evenly, thereby reducing the impact force and flow rate of the fluid on the tobacco leaves.

[0035] Exemplarily, the adjustment mechanism 4 can be configured as a bolt 41 and a nut 42, the nut 42 is disposed at the other end of the support portion 3, a threaded hole (not shown) is disposed inside the diffuser 2, and the bolt 41 passes through the nut 42 and is threadedly connected to the diffuser 2.

[0036] The nozzle of the utility model can be provided with a threaded hole inside the diffuser 2, and the adjusting mechanism 4 connected to the diffuser 2 can select the bolt 41 and the nut 42, so that the operator can adjust the distance between the diffuser 2 and the outlet end 12 of the base 1 according to actual needs, and the operator can replace the diffuser 2.

[0037] Exemplarily, the diffuser 2 can be selected from a sphere, a cone, a cylinder or an ellipsoid, and the present application does not limit this. The operator can select the shape of the diffuser 2 according to actual needs so as to better disperse the fluid to reduce the impact force and flow rate of the fluid, thereby reducing the crushing of the tobacco leaves.

[0038] In some embodiments, the size of the diffuser 2 can be selected from a variety of specifications such as 20mm, 25mm, 30mm, 35mm, 40mm, etc. according to the impact force of the fluid or the required fluid scattering direction, and the present application does not limit this.

[0039] Specifically, Figure 3 and Figure 4 As shown, the support portion 3 further includes a mounting plate 31 , the mounting plate 31 is provided with a mounting hole 32 , and the bolt 41 passes through the mounting hole 32 to be connected to the diffuser 2 .

[0040] The nozzle of the utility model can be provided with a mounting plate 31 on the support portion 3 and a mounting hole 32 on the mounting plate 31 , so that the operator can adjust the relative position of the diffuser 2 and the outlet end 12 of the base 1 and fix the diffuser 2 and the mounting plate 31 .

[0041] Furthermore, the support portion 3 is provided with a plurality of support rods 33 at intervals along the circumferential direction, one end of each support rod 33 is connected to the outlet end 12 of the base 1, and the other end of each support rod 33 is connected to the mounting plate 31, and a plurality of gaps 34 can be formed between each support rod 33. The plurality of support rods 33 are arranged at intervals along the circumferential direction at the outlet end 12 of the base 1, that is, gaps 34 are left between the support rods 33, so that the fluid dispersed by the diffuser 2 can be sprayed onto the tobacco leaves more evenly and smoothly.

[0042] Exemplarily, the material of the base 1, the support part 2 and the diffuser 3 is stainless steel to improve the structural strength of the device and ensure the service life of the device.
