Such devices are usually organic matter, or even part of a refinery. The refining tank of this equipment is dissolved in the refining tank and a wave stirrer here. The device itself mainly includes a stirring container stirrer. The stirrer immersed in the container is a rod-shaped and vertical. It includes a head which is completely covered by the melt. blade. [Prior art] Patent WO 9615071 A has proposed a mixer for glass melts. Here the melt is continuously homogenized. Patent D D-2 9 8 7 6 7 A Lifting device of cylindrical mixing container. The stirring point of the stirring space for immersing the melt in the mixing patent SU-9 145 10 B proposes a stirring device, and the smaller diameter of the end is at the lower plane. This conical stirrer is provided with a flow on the stirring blades to fully mix the surface layer. The wave stirrer or dispersing device known so far is satisfactory. It is often found that although the ripples in the stirring zone are lost, they thicken again after leaving the stirring zone. 312 / Invention Specification (Supplement) / 92-06 / 92109041 Especially the glass melting device is glass, melting and crystallization often includes a melting tank, a connection or processing device. , Such as a crucible, and a stirred substance. The stirring handle and the lower part of the stirring head are usually provided with a stirrer in an input pipe to stir the flow direction of the glassy melt to form a stirrer, extend into a circle and divide into two stirring spaces, outside the symmetry axis of the two container . The stirring of a truncated conical end of the appliance, the larger diameter is in the melt and water flakes, the result of which the glass melt is not all can be made thinner and more or less disappeared. In this case, the stirrer needs to be improved. 200400161 Speed. However, increasing the speed requires higher energy and may not achieve the goal. Other disadvantages are that if the speed is increased, the stirrer is prone to deform when it is malfunctioning due to impurities. The stirring blades are particularly deformed. As a result, the service life of the agitator, the agitator bearing and the associated drive becomes shorter. Therefore, increasing the speed of the stirrer will lead to a very adverse so-called reboil effect. In addition to the mechanical disadvantages already mentioned, the suction effect of the stirring zone on the surface of the crucible is enhanced, so there is a risk of inhaling air. SUMMARY OF THE INVENTION The object of the present invention is to provide a device for agitating and processing a fluid, especially a glass melt, which has a better effect of processing, agitating and agitating corrugations than a conventional device. In addition, the mechanical load of the device is less than that of the conventional device. This object is achieved by the features of item 1 of the scope of patent application. The basic idea of the present invention is as follows: Not only a single agitator, but at least two agitators. Each stirrer usually has a stirring shaft and stirring blades that can be driven. The stirring shafts are parallel to each other, and the stirring blades are arranged on the stirring shafts and each has an axial distance. The mixing blades of two adjacent mixers are embedded in the gap between the mixing blades of each other. Therefore, the melt is forced to change its direction several times depending on the number of stirring blades. The stirring blade causes the melt particles at the stirring shaft to flow out radially and enter the overlapping area of two adjacent stirring blades, so a vortex is formed there to achieve the best uniformity. A high degree of agitation is particularly important for special glasses containing boron oxide. Because boron oxide on the melt level is extremely easy to evaporate, it is very necessary to effectively mix 312 / Invention Specification (Supplement) / 92-06 / 92109041 200400161. Especially display glass. Because this kind of glass requires higher temperature for melting, refining and stirring, and increases evaporation, it will adversely change the local glass composition. The device of the present invention has the following advantages:-low re-cooking rate (re-cooking rate is directly proportional to the speed of the stirrer)-low rate of deformation of the stirrer (precious metal stirring parts) when the impurities cause failure Significantly less-longer agitator life-suction effect of the stirring zone on the surface of the crucible is minimized-lower load on the agitating bearing and driver-less energy consumption The invention will be described in detail below with reference to the drawings. [Embodiment] The equipment shown in FIG. 1 includes a melting pot A, a refining pot B, and a stirring device C of the present invention. The melting pot A is usually melted by putting a so-called mixture or glass shards or both. The melt then flows through a groove 1 to the refining pot B, and from there flows through a groove 2 to the agitator C. The function of the agitation device is to stir the homogeneous melt so that it is free of undulations. The agitation device C includes a stirring vessel 3 and three agitators 4, 5, 6. The agitators 4, 5, 6 interact as follows: Each agitator has a stirring shaft and several sheet-shaped stirring blades. As shown in Figure 7 312 / Invention Specification (Supplement) / 92-06 / 92109041 200400161, the stirring blade of one stirrer is embedded in the gap of the stirring blade of the other stirrer. For details, please refer to the following figure. The stirring device shown in Figs. 2 and 3 is different from the stirring device of Fig. 1 and has two agitators 4, 5. The agitator 4 has a stirring shaft 4.1, and the agitator 5 has a stirring shaft 5.1. Each mixer is equipped with mixing blades 4.2, 5.2. In this embodiment, the stirring blade has a sheet shape, as shown in FIG. 3. Two stirrers 4, 5 are placed in a stirring vessel 3. The stirring vessel has a melt stream inlet 3.1 and a melt stream outlet 3.2. It can be seen from FIG. 3 that the sheet-like stirring blades 4.2 and 5.2 have an overlapping area (shaded area). The direction of rotation of the stirrer can also be seen. Both agitators 4, 5 are rotated clockwise. The action mode is as follows: In the overlapping area of the stirring blade 4.2 and the stirring blade 5.2, close to the stirring shaft 4.1, the circumferential speed of the stirring blade 4.2 is small, and the stirring blade 5.2 is a circumferential part, so the circumferential speed is large. Close to the stirring axis 5.1 and vice versa. Here, the peripheral speed of the stirring blade 4.2 is larger, and the peripheral speed of the stirring blade 5.2 is smaller. In the center of the overlap area, which is half of the distance between the two stirring shafts 4 · 1, 5 · 1, the peripheral speeds of the two stirring blades 4.2 and 5.2 are the same. This means that the sum of the peripheral velocities of the opposite parts of the two adjacent stirring blades 4.2 and 5.2 in the radial direction is the same. Therefore, in the radial direction, the shear force acting on the volume of the glass melt in the overlap region is the same. This means that every part of the melt volume is treated the same. This is advantageous for a good energy effect. 8 312 / Invention Specification (Supplement) / 92-06 / 92109041 200400161 However, the two stirring shafts can also rotate in opposite directions. If the stirring shaft 4.1 rotates clockwise, the stirring shaft 5.1 rotates counterclockwise. Figure 4 is based on Figure 3. But here five stirring blades 4.2, 4.3, 4.4, 4.5, 4.6 are set. All stirring blades belong to five agitators not shown. All agitator structures are essentially the same, or even identical. The stirrer with the stirring blade 4.2 is set in the center, and the stirrers with the stirring blades 4.3, 4.4, 4.5, 4.6 are planetary symmetrically surrounding the central stirrer. Of course, it is also possible to provide four or more external agitators surrounding the central agitator. All changes in speed are possible. Besides blade stirrers, rod stirrers or stirrers with Kaplan turbine blades or marine propeller blades can also be provided. The stirring blade can be provided with protrusions, convex particles, notches and the like. The stirring blade may have an irregular shape, such as a wave shape in the axial direction. The agitating device of the present invention is particularly suitable for treating glass melts made of boron oxide or boron oxide and / or alkali metal oxides. The distance between adjacent stirring blades can be extremely small, for example only 2 to 5 to 10 mm. The stirring shaft can also be rotated at different speeds. For example, each stirring shaft is rotated at different speeds, and the same stirring shaft is rotated at different speeds.
