Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of supercharging mixing arrangement, as shown in Figure 1, comprise hybrid chamber 5, and to stretch in hybrid chamber 5 and the shaft 2 driven by power source, the top of described hybrid chamber 5 is communicated with material guiding hopper 3, the sidewall of hybrid chamber 5 offers liquid outlet 10, the bottom of hybrid chamber 5 is communicated with feed tube 9, residual liquid discharge port 7 is offered in the lower of feed tube 9, described power source is set up on hybrid chamber 5 by supporting construction 11, described shaft 2 vertically stretches in hybrid chamber 5, in hybrid chamber 5, material casting body 6 and agitator arm 8 are fixed on shaft 2 with backrest-type, material casting body 6 is upper, agitator arm 8 under.
Further, above-mentioned shaft 2 is connected with one end of adapter sleeve 13 by bearing 14, the other end of adapter sleeve 13 is connected with power source, and the installing plate 12 of adapter sleeve 13 side is connected with supporting construction 11 by bolt, and adapter sleeve 13 is provided with the lubricating grease injection channel of lubricating to bearing 14.
Further, above-mentioned power source is hydraulic motor or motor, also can be other can the device of output torque and rotating speed.
Further, above-mentioned material casting body 6 comprises throwing feeder dish 17 and material casting blade 18, as shown in Fig. 2 ~ Fig. 4,6 groups of material casting blades 18 are uniformly distributed, throwing feeder dish 17 is designed with threaded mounting hole 19, it is connected with agitator arm 8 by bolt, and the taper hole 20 throwing feeder dish 17 being also provided with band keyway 21 is connected with shaft 2.
Further, above-mentioned agitator arm 8 comprises impeller body 15 and stirring vane 16, as shown in Figure 5,6 groups of stirring vanes 16 are uniformly distributed, the bending direction of stirring vane 16 is consistent with the direction of rotation of shaft 2, as being clockwise direction in Fig. 5, impeller body 15 is provided with installing hole 22, and it is connected with material casting body 6 by bolt.
