Production Practice Of Continuous Washing Equipment

　　 Washing tank The control device of cloth volume is composed of transmission fence, proximity switch, cylinder, constant rotation active roller, passive roller and prismatic pulley. The fabric enters the rope washing trough through the mouth of the spray nozzle, and when its retention reaches a certain level, the fabric moves forward along the water to drive the barrier. When the transmission grating moves to a certain position, it opens the proximity switch. It is close to the switch command cylinder, and the cylinder pushes the passive roller to the normally rotating active roller. The rope fabric between the passive roller and the constant rotation roller is pressed along with the rotation direction of the roller, and is sent to the next water washing slot spray nozzle through the prismatic pulley. Considering that the length of knitted fabric is always changing in the process of infiltration and soaking, the mechanical distance of equipment is not equal to the length of fabric, and the retention of fabric in the washing tank varies with the length. When the amount of detention is reduced to a certain extent, the transmission barrier loses its propulsion force and drops freely, close to the switch at the same time, the cylinder loosens the passive roller, the passive roller rolls away from the usual rotation of the active roller, and the rope fabric loses pressure and suspends operation.

The key to prevent elongation is the rope running and the volume control of the washing tank. Automatic quantitative replenishment and rehydration device. The 5 tank washing tank in a single washing tank is divided into 2 wash tanks and 3 rinse tanks. The water in each cleaning unit is interworking. A set of automatic quantitative replenishment and rehydration device is installed for each cleaning unit. The device is composed of a constant pressure water source, a water valve, an electronic water flow gauge, a pulse quantitative pump and an auxiliary pool. The supplementary water is supplemented to the washing tank quantitatively under the control of constant pressure water and water valve. The electronic flow meter will input the flow signal into the pulse quantitative pump according to the set value. Washing process The data are stored in the quantitative control module, and the auxiliary concentration of the cleaning unit always keeps the set value. During the continuous washing process at different times, the fabric is washed under the same condition, so as to achieve the balance of the washing quality.

Energy saving and emission reduction reflux water device: flat sprinkler tank, channeling water washing tank, overflow overflowing tank overflowing water reuse: five groups of rope washing box ten cleaning units can be combined into soap washing area, water washing quality stability is good. Online automatic continuous quantitative replenishment and rehydration, soaping agent concentration to be measured and controlled, so that the fabric is always maintained under the same conditions of washing, to achieve the best washing effect. The overwashing area and the fixed color area can realize the overflow and reuse of the water to improve the energy saving and emission reduction effect.

　　 Knitted fabric It enters the open width sprinkler tank and the running water washing tank, and is evenly wetted by spraying and circulating water washing. Most of the size and floating color of the cloth are washed away, and the color and stain are effectively prevented. Fabric has little physical change. The low tension rope washing can overcome the tension of the fabric being stretched and deformed, so that the physical properties of the fabric remain unchanged. In the expansion tank, the knitted fabric is always soaked in water to avoid color and stain. Then it is pressed and dehydrated by the pressure roller immediately through the guide opening, and then enters the rope washing trough in a fluffy rope state. Complete the process of continuous soaping, washing and fixing. Finally, the whole washing process is completed continuously through vacuum dewatering, twisting and expanding and flat width falling cloth.
