1、 Due to the neglect of the function of stacked screw sludge dewatering machine by users and the non-standard market at present, many consumers seldom ask for relevant quality certification when purchasing stacked screw sludge dewatering machine. The tension of the filter belt of the screw type sludge dewatering machine is realized by the air cylinder, so that the whole filter belt can maintain constant tension, and the tension will not be changed due to the change of the feed volume, which is convenient for operation and management. The filter press has an air pressure control system which can automatically detect the position of the filter belt on the pressure roller and automatically correct the deviation. For the wide filter sludge dewatering device, it is also equipped with an automatic sludge feeding device Ensure the sludge into the filter belt evenly, so as to improve the filtration efficiency and prolong the life of the filter belt. For this stacked screw type sludge dehydrator, the manufacturer thinks that this not only makes the equipment we choose have no certificate to check, but also encourages the manufacturer to cut corners in production. Therefore, the manufacturer of stacked screw type sludge dehydrator reminds everyone to buy stacked screw type sludge dehydrator and provide quality certification to the manufacturer.
2、 Generally speaking, the quality certification of stacked screw sludge dehydrator is carried out by the industry and Commerce and Quality Supervision Department of the place where the production manufacturer is located according to the dehydrator's own characteristics and user's use characteristics. Whether it is certified or not directly determines the performance of the stacked screw type sludge dewatering machine and whether there will be safety accidents in use. Therefore, it can be seen that the quality certification sheet has a profound influence on the actual performance of the stacked screw sludge dewatering machine.
3、 However, the stacked screw sludge dewatering machine without quality certification can not be said to be totally unqualified )、 It's not reliable, but there are still a few manufacturers aiming at this characteristic. Since they don't go to the certification, the corresponding material selection doesn't have to be too careful, and the corresponding manufacturing process doesn't have to be too fine. The sludge dewatered by the screw type sludge dehydrator is generally easier to store and transport than the concentrated or liquid sludge : Generally, sludge is required to be dewatered before incineration to remove water from sludge and increase calorific value. Sludge is also required to be dewatered before landfill to reduce the amount of leachate produced in landfill. With the filter cloth moving into the pressurized dewatering area, the sludge of the stacked snail sewage treatment equipment is arranged between six vertical rollers, with the roller diameter decreasing from large to small, and the pressure increasing from small to large. With the shear force generated by the upper and lower filter cloth changing the upper and lower positions between different rollers, the sludge in the glue sludge is squeezed out to produce dry sludge cake. In this way, there will be a batch of screw type sludge dehydrators that cut corners. However, due to the limitation of professionalism, even if these stacked screw sludge dehydrators are shoddy, few of our consumers can see it. For those who have passed the quality certification, these problems will not appear.
Therefore, for our consumers, in order to ensure our legitimate rights and interests and the cost performance of the stacked screw sludge dewatering machine, we must obtain the corresponding quality certification when we purchase the stacked screw sludge dewatering machine. And because each quality certification document has a corresponding period of validity. Therefore, we need to pay attention to the validity period while observing whether the certification is accurate.
