Moistening & Water Supply Diagram
Steam consumption is reduced by 30??40%;Water consumption is decreased by 80%;
Since 2012, Super Humidifier technology has been successfully and widely used in the steamer of Beifa Company, which is a milestone in the field of long loop steamer processing;
Steam forms a high-speed air flow in the negative pressure chamber to generate negative pressure through the slit, water is sucked out from the pipeline,and mixed with the steam completelyin the mixing chamber; there is absolutely no nozzle blockage,greatly reducing the water consumption;it can be disassembled & assembled without shutdown;
Patent of Beifa Company:ZL 201620520309.8
Cloth-feeding &discharging box:Designed with the mode of cloth feeding &discharging in the middle to facilitate the feeding& output of knitted fabrics, elastic fabrics and fine fabrics. Heating and ventilation devices are used in the feeding &discharging devices to prevent steam spilling over and dripping water;
The cloth feeding roller uses silicone rubber strip toincrease friction, and the fabric has no contact with theprinting surface in the loop formation process; The superheated steam forming loop nozzle can prevent the waterdroplets forming in the loop formation process of fabric,increase the moisture of the fabric surface, make the fabricloop formation stable and achieve the function to eliminatestatic electricity;
Intermediate box: Building-block box structure,consistingof a number of intermediate boxes(determined by the clothcapacity);There are two sets of Super Humidifier nozzle devices ineach intermediate box for automatic humidification,and they arecontrolled separately. The electronic temperature control systemcan adjust automatically according to each fluctuation of thetemperature in the box,and the control precision reaches ±1℃.Any slight change of the temperature in the steaming box will trigger the pneumatic Y-valve,which willadd atomized water to the steam circulation system
Each intermediate box contains a high-temperatureheating system, which is suitable for the dyeing of dispersedyes and the adhesion of pigment printing; the high-temperature heating system can also be used for rapid heatingin the cold state of low-temperature process production andshorten the production preparation time.
Chain runs continuously and smoothly without impact,fabric loop formation is also continuous. The hanging rod running smoothly and rotating smoothly are two major elements to prevent friction between fabrics;it is especially applicable for new digital printing technology;
Patent of Beifa Company: ZL 201620520307.9、ZL 2017 20581131.2
Adjustment of the hanging rod spacing:The standard hanging rod spacing of steamer is 100 mm,and the fabric inevitably rubs against each other in the process of loop formation; for traditional printed fabrics (flat screen printing and garden screen printing) or color-insensitive printed fabrics,such mutual friction will not produce staining; But for new digital printed fabrics or particularly fine printed fabrics,this kind of mutual friction will produce staining and result in steaming defects; However, with the adjustment technology of hanging rod spacing, the number of hanging rods in the steaming box can be reduced by half, which changes the hanging rod spacing into 200 mm,so that the staining problem of new digital printing fabric or particularly fine printing fabric can be eliminated thoroughly! The adjustment of hanging rod spacing does not need to increase additional costs,on the premise that the machine must be in the cold state;take out half of the hanging rod inside,turn the knob on the control box to the corresponding spacing, it is just to adjust
cloth capacity and steaming time on the touch screen, all of which only takes about 10 minutes!
Similarly, to restore the standard hanging rod spacing,add the hanging rod into the steaming box,turn the knob on the control box to the corresponding spacing, adjust the cloth capacity and steaming time on the touch screen,which can be completed in about 10 minutes!
The way of producing saturated steam:Steam is fed into the steam-water mixers in the several water tanks (the quantity is deter mined by cloth capacity) to boil water, which is arranged at the bottom of the stea
(Patent of Beifa Company:ZL2017 20580984.4)
The steam-water mixer is fixed below the water surface.The steam is ejected from the nozzle to produce a high-speed airflow, which forms a negative pressure in the mixing chamber. Thewater outside the mixer is absorbed by the four intake ports in the mixing chamber,converged with the high-speed steam flow and is ejected from the water surface below by a double-layer steam nozzle so as to greatly improve the steam humidity; The steam humidity is determined by the steam pressure; the higher the steam pressure is, the faster the nozzle flow speed and the more sufficient the mixing degree of steam and water is, the higher the steam humidity is; on the contrary, the lower the steam pressure is, the slower the nozzle flow speed and the lower the mixing degree of steam and water is,the less the steam humidity is;
C.Technological adaptability
1. Disperse process: each room with independent temperature control system, each room's constant temperature is stable with a very small temperature difference; the normal temperature of a disperse process is±1℃,unique wetting apparatus and humidification devices for each room make the colors more bright; conducting oil heating way and reasonable radiatorr design(rolling chip)make it more speedy and energy saving heating for the machine.
2. Active process: based on allocation of spread process with constant temperature and when Active process heating rapid up to 102 C, the unique steam generator saturation moisture content began to play its major characteristics. The steam with maximum moisture content in faster and closest way through the circle offans even enter the steam box,enabling full absorption of the fabric in the steam box,also heating release at the meantime. In the course of exothermic, the temperature of steam box rising. At this moment,number of measurement points startup humidification devices. Then
ultra-fine and a lot of fans willbe the role of aerosol in the next cycle to add to the steam box. This action both balances of the process of setting a constant temperature and also remains major humidity in steam box to make
