Abstract
The utility model discloses a kind of feeding screw, it comprises spiral cylinder, described spiral cylinder one end is spiral discharging end, the other end is spirally mounted prots, in described spiral cylinder, screw shaft is installed, spiral charging short circuit is installed above described spiral cylinder, and described spiral charging short circuit is positioned at directly over screw shaft, the shape of described spiral discharging end cross-sectional plane is circular and the diameter of this circle is 100-150mm, and the shape of described spirally mounted prots cross-sectional plane is circular and the diameter of this circle is 200-300mm.The beneficial effects of the utility model are: the generation of the phenomenons such as feeding screw of the present utility model avoids raw material to melt, harden, and improve the stability that Molten salt chlorination furnace is produced.
Description
Technical field
The utility model relates to Molten salt chlorination furnace feed arrangement, is specifically related to a kind of feeding screw.
Background technology
In existing Molten salt chlorination furnace production process, almost all adopt feeding screw, as the feed arrangement of chlorination furnace, in chlorination furnace production process, by high hopper and blanking short circuit, powder raw material is delivered to feeding screw wherein one end, and pass through the rotation of screw shaft in feeding screw, powder raw material is delivered in Molten salt chlorination furnace and participates in titanium tetrachloride preparation feedback, the high-temperature gas of 700-1000 DEG C can be produced in course of reaction, this gas can be entered in blanking short circuit and high hopper by the installation passage of feeding screw and come in contact with powder raw material, the fusing point producing the powder raw material of titanium tetrachloride due to chlorination furnace is about 650 DEG C, a large amount of high-temperature gases enters in blanking short circuit and high hopper, can directly cause raw material to melt, the phenomenon such as harden, chlorination furnace raw material supply is directly caused to stop, cause a series of unusual conditions that composition transfer and composition transfer in chlorination furnace bring.
Because general spiral is the ribbon that equidistantly distributes, do not possess and set up material envelope ability and moment is less, in chlorination furnace High Temperature Gas know from experience enter furnace roof material dosing bin along helical duct, then cause material in whole Feed system harden and screw shaft stuck cause chlorination furnace feed interrupt so that directly affect chlorination furnace production stability.
Utility model content
The utility model overcomes feeding screw in prior art and easily causes High Temperature Gas cognition in chlorination furnace to enter furnace roof material dosing bin along helical duct in the course of the work, there is the deficiency that chlorination furnace feed interrupts and then directly affects chlorination furnace production stability, provide and solve a kind of feeding screw avoiding high-temperature flue gas to enter blanking short circuit and high hopper in the course of the work.
For achieving the above object, the utility model is by the following technical solutions:
A kind of feeding screw, it comprises spiral cylinder, described spiral cylinder one end is spiral discharging end, the other end is spirally mounted prots, in described spiral cylinder, screw shaft is installed, spiral charging short circuit is installed above described spiral cylinder, and described spiral charging short circuit is positioned at directly over screw shaft, the shape of described spiral discharging end cross-sectional plane is circular and the diameter of this circle is 100-150mm, and the shape of described spirally mounted prots cross-sectional plane is circular and the diameter of this circle is 200-300mm.
Further technical scheme is, the shape of described spiral discharging end cross-sectional plane is circular and the diameter of this circle is 125mm.
Further that to be the shape of described spirally mounted prots cross-sectional plane be technical scheme is circular and the diameter of this circle is 250mm.
Further technical scheme is, described spiral cylinder adopts corrosion-resistant steel to make.
By by the shape of spiral discharging end cross-sectional plane being circle in the technical program, and the diameter of this circle is 100-150mm, the shape of spirally mounted prots is circular, and the diameter of this circle is 200-300mm, thus the barrel of spiral cylinder is obliquely installed from spirally mounted prots to spiral discharging extreme direction, be convenient to make granular material to be subject to the extruding of barrel in by the process of spiral cylinder by the improvement of this spline structure and form material envelope, thus stop high-temperature gas to enter blanking short circuit and high hopper by spiral cylinder, thus avoid raw material to melt, the generation of the phenomenon such as to harden, improve the stability that Molten salt chlorination furnace is produced.
Simultaneously by adopting corrosion-resistant steel to make spiral cylinder in the technical program, thus further improve the service life of feeding screw.
Compared with prior art, the beneficial effects of the utility model are:
The generation of the phenomenons such as feeding screw of the present utility model avoids raw material to melt, harden, improves the stability that Molten salt chlorination furnace is produced.

Fig. 1 is the structural representation of a kind of feeding screw of the utility model.
As shown in Figure 1, wherein corresponding Reference numeral name is called:
1, spiral discharging end, 2 spiral cylinder, 3 spirally mounted prots, 4 screw shafts, 5 spiral charging short circuits.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of feeding screw as shown in Figure 1, it comprises spiral cylinder 2, described spiral cylinder 2 one end is spiral discharging end 1, the other end is spirally mounted prots 3, in described spiral cylinder 2, screw shaft 4 is installed, spiral charging short circuit 5 is installed above described spiral cylinder 2, and described spiral charging short circuit 5 is positioned at directly over screw shaft 4, the shape of described spiral discharging end 1 cross-sectional plane is circular, and the diameter of this circle is 100-150mm, the shape of described spirally mounted prots 3 cross-sectional plane is circular, and the diameter of this circle is 200-300mm, described spiral cylinder 2 adopts corrosion-resistant steel to make.
According to an embodiment of the present utility model, the shape of described spiral discharging end 1 cross-sectional plane is circular and the diameter of this circle is 125mm.
According to an embodiment of the present utility model, the shape of described spirally mounted prots 3 cross-sectional plane is circular and the diameter of this circle is 250mm.
Above detailed description of the invention is described in detail to essence of the present utility model; but can not limit protection domain of the present utility model; apparently; under enlightenment of the present utility model; the art those of ordinary skill can also carry out many improvement and modification; it should be noted that these improve and modify all to drop within claims of the present utility model.
