The two sides of each water tank are respectively provided with a water inlet and a water outlet, and the water inlet is higher than the water outlet.
And angle steel is welded on two lower side edges of each water tank respectively.
The invention has the advantages that:
the invention achieves better sealing effect than refractory cotton and glass fiber cloth by using water sealing on the basis of the movable flue, and prevents the untreated flue gas from overflowing to cause harm to the environment.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
fig. 3 is an enlarged view of a portion B of fig. 2.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.
As shown in fig. 1 and 2, the invention is applied to a rotary kiln, the kiln 1 is provided with a drying section, a preheating section, a roasting section and a cooling section, the kiln 1 is positioned in a circular operation channel, a kiln ceiling 2 is arranged above the position of the kiln 1 on the operation channel, and a flue 3 is hung at the middle position of the kiln ceiling 2;
channel steel 31 is fixed on the inner sides of two sides of the bottom of the flue 3, an 8# channel steel 4 is adopted to be buckled and welded on the channel steel 31 respectively to serve as a track for the movable bottom plate wheel to run, and the interval between the left 8# channel steel 4 and the right 8# channel steel 4 is 1170 mm; deep groove ball bearings 5 (model 6305-LZ) with sealing rings are respectively supported on the No. 8 channel steel 4 in a rolling manner, the deep groove ball bearings 5 are wheels, the deep groove ball bearings 5 are fixed on a shaft 51 with the diameter of 30mm, and the length of the shaft 51 is 180 mm.
