Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further detail:
The discharge gate of a kind of modified airslide disintegrating mill crushing chamber as shown in Fig. 1 to Fig. 4, described airslide disintegrating mill crushing chamber 1 is made up of grading wheel 2, nozzle 3 and discharge gate 4 parts, described airslide disintegrating mill crushing chamber 1 is also provided with for changing and check the hand hole 17 of nozzle 3 and the manhole 18 for overhauling grading wheel 2, described discharge gate 4 comprises tremie pipe 6 and seal cover board 7, and for connecting and the jockey of fastening described tremie pipe 6 and described seal cover board 7 and fastener, described jockey and fastener are symmetricly set on the both sides of described tremie pipe 6 respectively; Described jockey is made up of with the revolving member 10 being welded on seal cover board 7 side the component 9 that is connected and fixed being welded on tremie pipe 6 side, be connected and fixed described in U-shaped support 11 on described revolving member 10 is fixedly connected on component 9, described U-shaped support 11 is free to rotate; Described fastener is made up of with the component 14 that is fastened and fixed being welded on seal cover board 7 side the movable part 13 being welded on tremie pipe 6 side, and described movable part 13 comprises hasp 15 and handle 16, is fastened and fixed on component 14 described in described hasp 15 is overlapped on.
As shown in Figure 5, the discharge gate of the airslide disintegrating mill crushing chamber before improvement is as follows:
Discharge gate 4 before improvement adopts screw 5 pairs of tremie pipe flanges 6 to be connected with seal cover board 7 and fastening, and the quantity of screw 5 is 8 right.
The discharge gate design of the airslide disintegrating mill crushing chamber after improvement is as follows:
Tremie pipe 6 is improved, eliminates the flange of tremie pipe 6.
Seal cover board 7 is improved, eliminates the flange of seal cover board 7, increase bossing in seal cover board 7 inside, ensure better to seal between tremie pipe.
Increase plastic cushion sheet 8 between tremie pipe 6 and seal cover board 7, guarantee sealing effectiveness further.
Specific jockey and fastener is adopted to carry out being connected with fastening between tremie pipe 6 with seal cover board 7.
