Common card dust collectors are located in underground ducts, tube condensers and dust collectors may also be overhead. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Each branch duct cake can be a separate or combined total dust air channel leading to the chamber. Dust pipes are free from dust mixing, fibers, or even mis-insertion accumulation, this situation should be considered to reduce the total wind speed in the wind tunnel because of the shutdown of the machine part.
(For example, when the cotton is 4000 meters SI each capacitor, each card fan SI2500 meters) The design wind speed of the duct is generally 12 to 14 m/s, depending on the air speed and volume of each air passage, the wind speed and volume of each duct can be calculated. cross-sectional area. Personnel returning to the dust filter room of the carding machine and returning to the workshop must have an axial flow fan to adjust the return air. The general air duct leading to a bag filter is often equipped with a relay control fan, as shown in Figure 2-53. This is not only beneficial for students to overcome the large resistance in various pipes and reduce losses, but also facilitates the removal of the carding machine. The uniformity of impurities and cotton laps; it can also make negative pressure in different air ducts to avoid dust-laden air from escaping when air leakage occurs.
The total exhaust air volume of the relay China fans should be 10-20% larger than the total air volume of the Kaijie cotton dust removal system fans. When the dust-laden air is led to the collective bag of the dust filter room, there are two types of air intake: downwind and upwind. As shown in pavilion 2-54, some dust can be deposited in the hopper or ash chamber below, and the pipe may not have to go any further.
Upwind allows downdrafts to help dust and fibers fall, reducing build-up in bags. However, it was necessary to increase the building height and even use relay fans to keep the air intakes from accumulating flowers. For example, in order to maintain a certain wind speed at the inlet, the dust-laden air should be evenly distributed in the inlet pen, reduce the flow rate, eliminate the dead angle, and there should be a certain distance between the inlet and the bag inlet in the vertical and horizontal directions.
