[0001] The utility model relates to the technical field of superheaters, in particular to a steam superheater capable of reducing the occurrence of water hammer. Background Art

[0002] The cut stem feeder is a key production equipment in the tobacco industry's silk production line. Its function is to feed flue-cured tobacco, tobacco stems, and cut stems to improve the taste of the materials and meet various requirements such as flavor enhancement, moisture retention, and mildew prevention. During the production process of the cut stem feeder, the steam needs to be heated and dried, and a steam superheater needs to be used to dry the steam. However, when the steam is dried in a superheater, the heat pressure in the superheater increases rapidly, which can easily lead to water hammer, causing the cut stems to become wet and clumping, affecting the quality of the cut stem products.

[0003] Therefore, in view of the above problems, a steam superheater capable of slowly increasing pressure and reducing the occurrence of water hammer is now developed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0020] A steam superheater that reduces the occurrence of water hammer, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes an outer tube 1, an air inlet pipe 2, an air outlet pipe 3, a heating pipe 4 and a first mounting bracket 41. The front side of the left portion of the outer tube 1 is connected to the air inlet pipe 2 for inputting steam, and the rear side of the right portion of the outer tube 1 is connected to the air outlet pipe 3 for outputting hot water vapor. The air inlet pipe 2 and the air outlet pipe 3 that are not adjacent to each other are connected with an arc surface to facilitate threaded connection with an external pipeline. A plurality of first mounting brackets 41 are connected to the inner wall of the outer tube 1, and a plurality of heating pipes 4 for heating and drying steam are connected between the first mounting brackets 41. A circulation mechanism 5 is also included. The circulation mechanism 5 includes a mounting member 51 and a circulation pipeline 52. The left and right sides of the outer tube 1 are connected to the mounting members 51, and a circulation pipeline 52 for circulating pressure relief is connected between the mounting members 51.

[0021] This device can be used when drying and heating the steam in the pipe of the shredded stem feeder. It should be noted that, first, the boiler steam pipe is connected to the air inlet pipe 2, and then the boiler is used to inject steam into the heating pipe 4 through the air inlet pipe 2, so that the heating pipe 4 heats the steam. At the same time, the air pressure in the outer cylinder 1 is continuously increased due to the heat. At this time, the circulation pipe 52 continuously circulates and relieves the pressure in the outer cylinder 1, thereby reducing the possibility of water hammer on the inner wall of the outer cylinder 1. Then the heated steam can be discharged through the outlet pipe 3. In summary, the air pressure in the outer cylinder 1 is continuously relieved through the circulation pipe 52, so that the pressure in the outer cylinder 1 is slowly increased, thereby reducing the possibility of water hammer and ensuring steam drying.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes a protection mechanism 6, which includes a second mounting frame 61, a placement frame 62 and an upper cover 63. The upper part of the middle part of the outer tube 1 is connected to the second mounting frame 61, and the upper part of the second mounting frame 61 is connected to the placement frame 62 for placing the circulation pipe 52. The front edge of the placement frame 62 is provided with a plurality of heat dissipation grooves, and a plurality of ribs are connected between the second mounting frame 61 and the lower sides of the front and rear parts of the placement frame 62. The upper part of the placement frame 62 is slidably connected to the upper part of the placement frame 62 for covering the placement frame 62, and a handle is connected to the upper rear side of the upper cover 63.

[0023] It should be noted that during daily maintenance of the circulation pipe 52, the upper cover 63 is slid backward so that the upper cover 63 no longer covers the placement frame 62, and the circulation pipe 52 in the placement frame 62 is then inspected. After the inspection is completed, the upper cover 63 is slid forward and reset. In summary, the circulation pipe 52 is protected by the upper cover 63 and the placement frame 62, making the circulation pipe 52 safer in daily use and extending the life of the circulation pipe 52.

[0024] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
