Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco leaf processing equipment in the tobacco industry, and more specifically to a device for eliminating condensed water from a material head of a steam injection nozzle. Background Art
[0002] Dual-medium nozzles are commonly used in the tobacco industry to add water and materials to tobacco materials. Dual-medium nozzles are key components for adding water and materials to tobacco materials. Due to the process requirements of different processes, the ejection media of dual-medium nozzles are mainly divided into two categories: steam and compressed air. Steam will condense into water due to cooling in the pipeline, and a drain device needs to be installed on the steam pipeline. Although a drain device is installed on the existing steam pipeline, there is no drain device on the pipe section between the ejection steam valve and the dual-medium nozzle. If the equipment is stopped for a long time, the steam in the steam pipeline after the ejection steam valve will condense into water. At the head stage, the condensed water accumulated in the steam pipeline will be sprayed onto the tobacco material in the form of raindrops or water columns, resulting in poor uniformity in the application of water (liquid) in the head, and material adhesion to the cylinder wall, affecting product quality. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and provides a device for eliminating condensed water at the head of a steam injection nozzle, so as to eliminate condensed water at a section of the injection steam pipeline close to the dual-medium nozzle, improve the uniformity of adding water (liquid) to the head part, and reduce the sticking of material to the cylinder wall.
[0004] The utility model is realized by the following technical solutions:
[0005] A device for eliminating condensed water from a steam ejector nozzle head, wherein two inlet ends of a dual-medium nozzle are respectively connected to an ejector steam pipeline and a liquid feed pipeline, an ejector steam valve is provided on the ejector steam pipeline, the ejector steam pipeline is cut off at a portion between the ejector steam control valve and the dual-medium nozzle to form two joints, the connection of the two joints is achieved through a three-way valve, and the three-way valve is arranged close to the dual-medium nozzle, the inlet end and one of the outlet ends of the three-way valve are respectively connected to the two joints, and the other outlet end of the three-way valve is connected to a condensed water drainage pipeline.
[0006] As a preferred solution of the above-mentioned device for eliminating condensed water at the head of the steam injection nozzle, a liquid flow control valve is provided on the liquid pipeline.
[0007] Compared with the prior art, the utility model has the following advantages:
[0008] The utility model provides a device for eliminating condensed water at the head of a steam injection nozzle, which cuts off the injection steam pipeline at a position located between the injection steam control valve and the dual-medium nozzle, and introduces a condensed water drainage pipeline through a three-way valve. The condensed water at the position of the injection steam pipeline located between the injection steam control valve and the dual-medium nozzle can be discharged in time through the condensed water drainage pipeline, thereby eliminating the possibility of condensed water in the injection steam pipeline being sprayed onto the material, reducing the situation in which the steam injection port of the dual-medium nozzle cannot inject water (liquid material) due to condensed water at the head stage, reducing the quality risk of uneven water and material addition at the head stage, and effectively reducing the sticking of materials to the inner wall of the drum.

[0011] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0012] See also Figure 1 The present embodiment discloses a device for eliminating condensed water from a steam ejector nozzle head. The two inlet ends of the dual-medium nozzle 1 are respectively connected to an ejector steam pipeline 2 and a liquid feed pipeline 3. The liquid feed pipeline 3 is provided with a liquid feed flow control valve 4. The ejector steam pipeline 2 is provided with an ejector steam valve 5. The ejector steam pipeline 2 is cut off at a portion between the ejector steam control valve and the dual-medium nozzle 1 to form two joints. The connection of the two joints is achieved through a three-way valve 6. The three-way valve 6 is arranged close to the dual-medium nozzle 1. The inlet end and one of the outlet ends of the three-way valve 6 are respectively connected to the two joints. The other outlet end of the three-way valve 6 is connected to a condensed water drainage pipeline 7.
[0013] The device for eliminating condensed water in the head of the steam ejector nozzle provided in this embodiment is that the ejector steam pipeline 2 is cut off at the part between the ejector steam control valve and the dual-medium nozzle 1, and the two ends of the cut-off part are connected through a three-way valve 6, and the remaining outlet end of the three-way valve 6 is connected to the condensed water drainage pipeline 7. At the head stage, the outlet end of the three-way valve 6 connected to the condensed water drainage pipeline 7 is first opened, and the outlet end connected to the dual-medium nozzle 1 is closed, and the condensed water in the pipe section of the ejector steam pipeline 2 located between the ejector steam control valve and the dual-medium nozzle 1 is discharged. Then the outlet end of the three-way valve 6 connected to the condensed water drainage pipeline 7 is closed, and the outlet end connected to the dual-medium nozzle 1 is opened, and the ejector steam enters the dual-medium nozzle 1 through the three-way valve 6, and the water (liquid) enters the dual-medium nozzle 1 through the liquid pipeline 3. Under the action of steam ejection, the water (liquid) is atomized and evenly applied to the tobacco material, effectively preventing the condensed water in the ejector steam pipeline 2 from being sprayed onto the tobacco and causing product quality problems.
[0014] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
