. _ The new smart yarn steaming machine equipment <br> <br> a function and use:

Our multi-fiber wet/dry quick-setting steamer (hereinafter referred to as "steamer") is suitable for the textile industry and units using natural fibers and chemical fibers as raw materials. Its main purpose is to use continuous filaments with weaving conditions. After the consolidation and twisting, the shape is set, that is, the twist is stabilized at a certain pressure and temperature, and a balanced non-twisting thread is obtained, which is convenient for the processing of subsequent processes and improving the product quality.

The use of this steamer features: a wide range of applications, both wet and heat setting (the steam directly into the cylinder body) and dry heat setting (the steam directly into the jacket, the heat from the cylinder wall). The door is light and flexible, and the loading and unloading of the door is quick and convenient. The door seals well with the cylinder flange. The physical and mechanical properties of the product after shaping, such as strength and elongation, are not affected and the quality of the product is guaranteed.

Three. Expected product class production:

The nominal volume of the steamer is 4m3, and the actual effective volume is 3m3. Under normal circumstances, the weight of auxiliary equipment (such as trolleys, brackets, bobbin tubes, etc.) can be reduced by about 200-300 kilograms per product (merged after twisting). Time is calculated on one hour (including loading and unloading), and each class can shape 2 tons of products. (This figure also needs to be determined according to the specific conditions of each plant, for reference only).

Fourth, the role of the main components and maintenance:

(1) Cylindrical body (Dg1100×8): This part has two sections of steel plate welding with δ=8mm and welding with Dg1100×8 head. The inner diameter is Ф1100mm, and the effective length (depth) is about 2600mm. It has a surface area of ​​10m2 and a surface area of ​​4m3. Its main function is to hold the shape and shape of the product. When the damp heat is set, the internal chamber passes steam, and when the heat is set dry, it is cooled by the surface.

Maintenance: The cylinder body can not have long-term accumulation of water (steam cooling water), after cooling and heat setting, the cooling water should be drained and wiped dry, regularly check the inner surface for paint fall off and wipe off the phenomenon, if there should be timely coating high temperature protection Rust paint, to prevent partial embrittlement, use a maximum vacuum of 0.08 Mpa (actually 0.07 Mpa) to prevent instability.

(2) Jacket (Dg1200×6): This part has two sections of δ=6mm steel plate welding and Dg1200×8 head welding. The first section imitates the chemical reactor design - with 45 changes. This can reduce the size of the cylinder flange, but also increase the weight of the door. The inner diameter of the jacket is Ф1200 mm, and the actual volume of the air chamber is about 0.8 m3. Its main function is to store steam in the air chamber during dry heat setting. Under a certain pressure, heat is transferred to the drum body for so-called “dry steaming”.

Maintenance: According to the requirements of the drawings, 80mm to 100mm thick asbestos cement insulation layer shall be added on the outer surface of the jacket (add it after installation and adjustment of the use unit). The inner surface of the jacket and the outer surface of the cylinder have been provided with a high-temperature anti-rust paint according to the regulations before the final assembly. Therefore, after each use, only the cooling water in the jacket can be drained.

(3) Twenty support tubes and eleven attachment tubes: The thirty-one tubes were made of 108 steel tubes, DN25 seamless steel tubes and DN50 seamless steel tubes. The main role of the twenty-eight steel tubes is to separate the jacket from the cylinder and form a gas chamber in the middle. The eleven attachment tubes are: tube outlet pipe, safety valve tube, thermometer tube, pressure gauge tube, vacuum tube, intake tube, jacket pipe, safety valve tube, pressure gauge tube, and inlet tube A self-controlled instrument (see details in the drawing).

Maintenance: It should be noted that the tube teeth should not be damaged. Apply anti-corrosion lubricants such as molybdenum disulfide on the teeth before applying on the pipe, and ensure that it does not leak water or leak gas. If it is a flange connection, add mats.

(4) Body and gate flange components: The body flange is welded by two flanges, and the main flange of the “V” seal groove is Q235A high-quality carbon steel. Parts of the door flange that have been in contact with water vapor for a long time are also fitted with stainless steel rings. Therefore, the rust prevention problems of the two types of flanges have been completely solved, and the maintenance is also labor-saving, and it is only necessary to wipe off the moisture. The back of the “V” seal groove on the cylinder flange has two purple tube-connected screw holes. Compressed air (or direct use of boiler steam) passes through and the “V” seal ring is ejected, with the door flange The plane is aligned and pressure is applied to achieve the purpose of sealing.

(5) The door hanging foot bearing part: The door hanging foot (on the upper and lower) is not only welded together with the folded jacket, but also has reinforced support at the bottom, which greatly strengthens the rigidity of the hanging part and ensures that the door is easy to open and close. flexible.

Bearing part: There are three radial ball bearings (one on the next one), easy assembly and disassembly, easy to refuel. The diameter of the main shaft is Ф45mm, and the radial load and axial load of the gate are sufficient.

Maintenance: Mainly refueling the bearing part regularly (every two weeks), or pressurize the high-temperature butter (5-6 months) on a regular basis (when adding high-temperature butter, just unscrew the top cover to add oil)

(6) Activities, fixed blocks, rollers, racks, handles and other components: This part is mainly for the purpose of realizing quick opening, closing, sealing and other purposes of the device. All operations are completed by one person, which is easy and convenient. Due to its own weight, the upper roller wears faster. At a certain time, the upper roller can be switched to the lower one to ensure the rotation is flexible.

Maintenance: Should pay attention to the thread or other dirt into the roller, affecting the rotation, such as the roller again sluggish, can be appropriate to loosen the compression screw.

(7) Pressure gauges, thermometers, and safety valves: Pressure gauges, vacuum gauges, thermometers, safety valves, and other instruments are installed in the jackets and cylinders (there are pipe fittings that pass through and are installed on the top plate). In addition to complying with the required measuring range and accuracy class, appliances must also be checked for their sensitivity and accuracy on a regular basis. During use, they must not be allowed to increase their pressure and vacuum to avoid accidents.
