A. generation radial runout can be made, the gap between helicallobe and the inwall of charging line is impelled to increase, thus the material be stuck between helicallobe and the inwall of charging line is pitched, avoid the breakdown of equipment such as card machine.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But a kind of self-enclosed feeding screw of the present utility model is not limited to embodiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment, shown in Figure 1, a kind of self-enclosed feeding screw of the present utility model, comprises charging line 1, spiral pusher mechanism 4 and the driver train 7 for driving spiral pusher mechanism 4 to rotate, and the two ends of charging line 1 are respectively equipped with inlet point and discharging opening 2; Described charging line 1 comprises the propelling movement section and seal section that axially set gradually along it, and push section and be in inlet point side, seal section is in discharging opening 2 side; The external diameter of spiral pusher mechanism 4 is less than the internal diameter of charging line 1, and the length of spiral pusher mechanism 4 is less than the length of charging line 1, and this spiral pusher mechanism 4 is installed in the propelling movement section of charging line 1, and coaxially arranges with charging line 1.
Preferred as one, the utility model also comprises flexible supporting frames 8, this flexible supporting frames 8 is arranged in described charging line 1, described spiral pusher mechanism 4 comprises the axis S. A. arranged and the helicallobe being secured to this S. A. along described charging line 1, one end of S. A. adopts clutch shaft bearing 9 to be rotationally connected with flexible supporting frames 8, the other end stretches out outside described charging line 1, and is in transmission connection mutually with described driver train 7 through after end flanges 5, second bearing 6 be arranged at outside charging line 1 successively.
Preferred as one, the length of described seal section
wherein, a represents the natural packing angle of described seal section institute convey materials, and h represents the internal height of described charging line 1.
Preferred as one, the inlet point of described charging line 1 is located at the upper side of its one end, and is circumscribed with feeder hopper (3 or, also can be feeder); The other end end face of described charging line 1 is opened type structure, and forms described discharging opening 2.
Preferred as one, described driver train 7 comprises drive motor, and this drive motor is fixed on outside described charging line 1, and the axle drive shaft of this drive motor is in transmission connection with the other end of belt with described S. A. mutually by belt pulley.
A kind of self-enclosed feeding screw of the present utility model, during application, is connected it with columniform high temperature reaction stove 10.This high temperature reaction stove 10 inside is high temperature anoxybiotic environment, during charging need with extraneous air relative insulation.The wall of this high temperature reaction stove 10 has the mounting hole slightly larger than charging line 1 external diameter.The other end of charging line 1 adopts mounting flange 11 and elevated-temperature seal packing ring to be assemblied on the mounting hole of high temperature reaction stove 10, and fixes with bolt 12.In the present embodiment, the internal diameter of charging line 1 is 300mm, and the material that send is density is 0.7t/m
3coal ash, the natural packing angle of this material is 18 °, therefore, by calculate, the length L of the seal section of charging line 1 should be greater than 1.85m.
During feeding, material enters the propelling movement section of charging line 11 by feeder hopper 3.Propulsion source (drive motor) in actuating device 7 drives spiral pusher mechanism 4 to rotate by belt pulley, and spiral pusher mechanism 4 is pushed to seal section material from the propelling movement section of charging line 1.Along with increasing of material in seal section, solid accumulation height increases, and fills up seal section gradually.Therefore, by the accumulation of material in seal section, isolate the environment of a sealing anoxybiotic can to cylindrical reacting furnace 10.Along with the continuous propelling movement of spiral pusher mechanism 4, material produces slippage in seal section, finally enters in cylindrical reacting furnace 10 from the discharging opening 2 of charging line 1.When there being special-shaped material to be stuck between the helicallobe of spiral pusher mechanism 4 and charging line 1 inwall, S. A. due to spiral pusher mechanism 4 have employed single-ended resilient mounting mode, this S. A. is made to produce radial displacement, gap adaptability between the helicallobe of spiral pusher mechanism 4 and charging line 1 inwall increases, thus, can be pitched between helicallobe by card material, thus avoid equipment stuck, cause breakdown of equipment.
Above-described embodiment is only used for further illustrating a kind of self-enclosed feeding screw of the present utility model; but the utility model is not limited to embodiment; every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all fall in the protection domain of technical solutions of the utility model.
