Abstract
The utility model discloses a feed propelling device, which comprises a closed cavity body (7); a feed port (1) and a discharge port (6) are respectively formed at the top and bottom of the closed cavity body (7); straight rods (3) with helical blades (8) are arranged in the closed cavity body (7); one end of each straight rod (3) stretches out of the closed cavity body (7) to be connected with a motor (5) in a transmission way; the number of the straight rod (3) with the helical blades (8) are two; the two straight rods are arranged in parallel; and the helical blades (8) on the two straight rods are engaged with each other. With the adoption of the fee propelling device provided by the utility model, the calcium oxide can be digested more uniformly and more completely; and moreover, the stream and powder produced in the digestion process is discharged from the dust outlet of the top of the closed cavity body to enter the dust removing equipment, thus, the corrosion and damage to surrounding equipment can be reduced.
Description
Technical field
The utility model relates to feeding and propelling device, relates in particular to the feeding and propelling device of limeslaker.
Background technology
Limeslaker also is lime slaking machine, lime slaker; Be the specific equipment that unslaked lime (quicklime) is digested to milk of lime or slaked lime powder, be mainly used in industries such as steel-making, chemical industry, metallurgy, papermaking, power plant desulfurization, aluminum oxide, white titanium pigment, sugaring, bio-pharmaceuticals, soda ash manufacturing.Limeslaker has the part quicklime slaking in the process of assimilation of quicklime using inhomogeneous; Not thorough, the utilization ratio of unslaked lime is lower, and can produce steam and powder in the digestive process; This can produce corrosion and damage to surrounding devices; Reduce production efficiency, improve production cost, also can cause harmful effect people's health.
Summary of the invention
The technical problem that the utility model will solve is that quicklime slaking is inhomogeneous, and utilization ratio is lower, pollute bigger, provide for this reason a kind of can make quicklime slaking more evenly, more thorough and free of contamination feeding and propelling device.
The technical scheme of the utility model is: a kind of feeding and propelling device; It comprises that the top has the airtight cavity that opening for feed, bottom have discharge port; Said airtight cavity positioned inside has the straight-bar that has screw-blade, and said straight-bar one end stretches out airtight cavity and is connected with drive of motor, and the said straight-bar that has screw-blade has two; Two straight-bars are settled side by side, and the screw-blade on two straight-bars intermeshes.
The improvement of such scheme is that said airtight cavity top has the dust mouth.
The beneficial effect of the utility model is through adopting double-stranded feed thruster that unslaked lime is carried out duplex digestion; Thereby make quicklime slaking more evenly, thoroughly; And steam that digestive process produces and dust are discharged from the dust mouth, top of airtight cavity and are got into dust removal installation, reduce corrosion and damage to surrounding devices.
Description of drawings
Fig. 1 is the utility model synoptic diagram;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Like Fig. 1, shown in Figure 2; The utility model comprises and has the airtight cavity 7 that opening for feed 1, bottom have discharge port 6; Said airtight cavity 7 positioned inside have the straight-bar 3 that has screw-blade 8, and said straight-bar 3 one ends stretch out airtight cavity 7 and are in transmission connection with motor 5, and the said straight-bar 3 that has screw-blade 8 has two; Two straight-bars are settled side by side, and the screw-blade 8 on two straight-bars intermeshes.Two straight-bars drive the screw-blade rotation when digestion, and intermeshing screw-blade has guaranteed that digestion is more even, thoroughly.Steam that forms in the digestion and dust are discharged from the dust mouth 2 at airtight cavity 7 tops, get into dust removal installation.
The preference of the utility model is between motor 5 and straight-bar 3, to be connected with speed reduction unit 4, can control the velocity of rotation of straight-bar, and control more flexibly accurately can be regulated the digestion rate of burnt lime digester on demand in the quicklime slaking process like this.Discharge port 6 is arranged on the different vertical section of airtight cavity with opening for feed 1, and the time that unslaked lime is stopped in airtight cavity is longer, more helps abundant digestion.
Claims (2)
1. feeding and propelling device; It comprises that the top has the airtight cavity (7) that opening for feed (1) bottom has discharge port (6); Said airtight cavity (7) positioned inside has the straight-bar (3) that has screw-blade (8), and said straight-bar (3) one ends stretch out airtight cavity (7) and are in transmission connection with motor (5), it is characterized in that the said straight-bar (3) that has screw-blade (8) has two; Two straight-bars are settled side by side, and the screw-blade (8) on two straight-bars intermeshes.
2. a kind of feeding and propelling device as claimed in claim 1 is characterized in that said airtight cavity (7) top has dust mouth (2).
