Description

Technical Field

[0001] This utility model belongs to the technical field of filter rod production equipment, and in particular relates to a clean high-temperature steam system for a hollow filter rod for tobacco drawing. Background Technology

[0002] Hollow filter rods are produced by rapidly solidifying steam with glycerin-sprayed filaments. During the production process, steam is sprayed directly through the filaments. Because the drawn hollow filter rods come into direct contact with the human body, the cleanliness of the steam is crucial for quality control; the steam must meet food safety standards. Furthermore, the production process and speed requirements place extremely high demands on the steam's moisture content and outlet temperature.

[0003] Currently, domestic manufacturers all use steam generated from municipal water as their steam source. This produces steam containing many impurities, which can easily contaminate the filter rods. Furthermore, the existing steam systems cannot meet the process requirements in terms of moisture content and steam temperature after the first heating. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a clean high-temperature steam system for a hollow filter rod for tobacco.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A clean high-temperature steam system for hollow filter rods used in tobacco processing includes a water tank, a water pump, a steam generator, a first steam superheater, and a second steam superheater. The water tank, water pump, steam generator, first steam superheater, and second steam superheater are connected sequentially by pipes. The second steam superheater is connected to a machine base by a pipe. The water tank stores distilled water. The water pump draws the distilled water from the water tank to the steam generator for its use. The steam generator heats the distilled water to generate saturated steam. The first steam superheater provides preliminary heating to the saturated steam. The second steam superheater further heats the pre-heated steam before it is transported to the machine base through pipes.

[0007] Preferably, both the first steam superheater and the second steam superheater are equipped with steam traps.

[0008] Preferably, the output end of the steam generator is equipped with a first pressure gauge, and a pressure controller is installed on the pipeline connecting the steam generator and the first steam superheater.

[0009] Preferably, a pneumatic diaphragm valve, a second pressure gauge, and a first temperature gauge are installed on the pipe connecting the first steam superheater and the second steam superheater.

[0010] Preferably, a third pressure gauge and a second temperature gauge are installed on the pipe connecting the second steam superheater and the machine.

[0011] Preferably, a solenoid valve is installed on the pipe connecting the second steam superheater and the machine.

[0012] Preferably, the first and second steam superheaters are vertical steam superheaters.

[0013] The beneficial effects of this utility model are:

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This invention uses a first steam superheater and a second steam superheater to heat steam in multiple stages, allowing the steam sufficient heat exchange time. The heated steam has a lower water content and a higher heat exchange value; and using distilled water can produce clean steam. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, this utility model provides a technical solution: a clean high-temperature steam system for a hollow filter rod for tobacco, comprising a water tank 1, a water pump 2, a steam generator 3, a first steam superheater 4, and a second steam superheater 5. The water tank 1, water pump 2, steam generator 3, first steam superheater 4, and second steam superheater 5 are connected sequentially by pipes. The second steam superheater 5 is connected to the machine base by a pipe. The water tank 1 stores distilled water. The water pump 2 is used to draw distilled water from the water tank 1 to the steam generator 3 for its use. The steam generator 3 is used to heat the distilled water to generate saturated steam. The first steam superheater 4 is used to preheat the saturated steam. The second steam superheater 5 is used to further heat the preheated steam before it is transported to the machine base through pipes.

[0019] The working principle of this utility model is as follows: After the water tank 1 is filled with pure distilled water, it is pumped into the steam generator 3 by the water pump 2. At this time, the steam generator 3 starts to work. The steam generator 3 heats the distilled water to generate saturated steam, which is then transported to the first steam superheater 4 through the pipeline for preliminary heating. After the saturated steam is preheated, it is then transported to the second steam superheater 5 through the pipeline for reheating.

[0020] This invention uses a first steam superheater 4 and a second steam superheater 5 to heat the steam in multiple stages, allowing the steam sufficient heat exchange time. The heated steam has a lower water content and a higher heat exchange value; and using distilled water can produce clean steam.

[0021] Furthermore, both the first steam superheater 4 and the second steam superheater 5 are equipped with steam traps 6 to promptly remove moisture from the steam.

[0022] Furthermore, a first pressure gauge 7 is provided at the output end of the steam generator 3, and a pressure controller 8 is provided on the pipeline connecting the steam generator 3 and the first steam superheater 4. The steam pressure generated by the steam generator 3 is detected by the first pressure gauge 7, and the pressure controller 8 controls the pressure to keep it within the process range before it is delivered to the first steam superheater 4 for heating.

[0023] Furthermore, a pneumatic diaphragm valve 9, a second pressure gauge 10, and a first temperature gauge 11 are installed on the pipeline connecting the first steam superheater 4 and the second steam superheater 5, so as to detect the pressure and temperature of the steam heated by the first steam superheater 4 in real time, and after the pressure is reduced and stabilized by the pneumatic diaphragm valve 9, it is then sent to the second steam superheater 5 for heating.

[0024] Furthermore, a third pressure gauge 12 and a second temperature gauge 13 are installed on the pipe connecting the second steam superheater 5 and the machine tool, so as to detect the pressure and temperature of the steam heated by the second steam superheater 5 in real time, so that the pressure and temperature of the steam supplied to the machine tool are stable and controllable.

[0025] Furthermore, a solenoid valve 14 is installed on the pipe connecting the second steam superheater 5 and the machine base, thereby opening and closing the output end of the steam system of this utility model.

[0026] Specifically, the first steam superheater 4 and the second steam superheater 5 are vertical steam superheaters.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
