Salvation tank experimental device

Clear classes in water treatment usually include concrete, precipitation and filtration. The treatment objects are m--nly suspension and colloid impurities in water. After the raw water is added, the suspension of the water and the colloid in the water form a large particle flocculation, and then the gravity is separated by the sedimentation tank. Mechanical reaction oblique pipe sedimentation tank is a water purification structure with two functions: concrete and precipitated. This model is a demonstration device that displays the internal structure of the mechanical reaction tank and the oblique tube sedimentation tank. Hope to achieve the following purpose:

1. Directly observe the organic glass device to deepen the understanding of each part of the composition;

1. Product overview

** The rapid development of science and technology, the degree of automation of process control equipment is getting higher and higher, the process control equipment has more and more functions, and the operation has become more and more complicated. Many smart instrument devices are gradually being widely used. The skills of equipment m--ntenance and equipment personnel should also be continuously updated. This improves the theoretical and technical level and actual operating skills of technical workers, and enhances the competitiveness of workers under the conditions of new forms. This set of equipment can improve the ability of equipment m--ntenance, m--ntenance and operators to handle problems on the spot.

Second, systemic characteristics

1. The object system is a st--nless steel frame, and all devices are designed by st--nless steel and aluminum alloy

2. The secondary measuring instrument of the sensor is installed on the object, which is convenient for students to perform various operations at the scene

3. The control part uses the st--nless steel mesh board. The on -site signal is directly received by the wiring terminal to the measuring instrument, which enhances the students' hands -on skills. At the same time, the wiring of the on -site instrument is more intuitive.
