Description
Technical field
The utility model relates to rotary discharger, especially relates to the high gas-tightness rotating discharging device of spiral cavity storing self compensation plane contact type.
Background technology
At present, existing discharger with pressure reduction mainly is the vane type rotary discharger; Consisted of by rotary blade, housing etc., during work, rely on the hopper of five equilibrium on the rotary blade to realize when rotated uniformly to material unloading function; Its air-tightness principle all is to rely on the radial and axial end clearance reduce rotary blade and housing to realize, is the splash that can not cause because of Leakage Gas material under pressure during convey materials to bubble-tight requirement, the normal conveying of assurance material.Structurally, its sealing band (or sealing area) is the radial and axial contact surface of rotary blade sheet and housing, therefore sealing band is longer, require all sealing bands all normally to seal the air-tightness that can guarantee rotary discharger during work, on airtight principle, the longer leak tightness of sealing band is poorer.
Summary of the invention
The utility model purpose is to provide a kind of spiral cavity storing self compensation plane contact type high gas-tightness rotating discharging device.
For achieving the above object, the utility model is taked following technical proposals:
The high gas-tightness rotating discharging device of spiral cavity storing self compensation plane contact type described in the utility model, comprise horizontally disposed barrel shell and be horizontally set on the interior impeller assembly of described barrel shell, extend respectively outside the left and right end cap of barrel shell at the paddle shaft two ends of described impeller assembly, the left end of described paddle shaft is connected with described left end cap sealed rotational by the bearing body on the left end cap, and the right-hand member of described paddle shaft is connected with described right end cap sealed rotational by the bearing body on the right end cap; Described paddle shaft is made of power input shaft and blade installation shaft; Described power input shaft and blade installation shaft connect by cross coupler, offer vertically annular groove on blade installation shaft and end face that power input shaft is connected, in described annular groove pressure spring are installed; Be fixed with the annular abrasion-proof backing block that the blade with impeller assembly fits tightly at the right end cap inside face, be communicated with respectively feeding cylinder and discharge barrel at upside and the downside of right end cap.
Described impeller assembly is fixedly set in right opening cylindrical shell on the described blade installation shaft by level vertically, and the external diameter of described right opening cylindrical shell is less than the internal diameter of described barrel shell; The interval is fixed with a plurality of blades vertically on the blade installation shaft that is positioned at right opening cylindrical shell, and described a plurality of blades are along the radially equal distribution of circumference, and each blade all reverses 180 ° along the axle center axial screw of blade installation shaft.
The utility model advantage guarantees higher lock gas air-tightness when being to be implemented under the pressure reduction operating mode evenly discharging, and can realize when discharging is worked that auto-compensation weares and teares.

The specific embodiment
As shown in Figure 1, 2, 3, the high gas-tightness rotating discharging device of spiral cavity storing self compensation plane contact type described in the utility model, comprise horizontally disposed barrel shell 1 and the impeller assembly that is horizontally set in the described barrel shell 1, extend respectively outside the left and right end cap 2,3 of barrel shell 1 at the paddle shaft two ends of described impeller assembly, the left end of described paddle shaft is connected with described left end cap 2 sealed rotational by the bearing body 4 on the left end cap 2, and the right-hand member of described paddle shaft is connected with described right end cap 3 sealed rotational by the bearing body 5 on the right end cap 3; Described paddle shaft is made of power input shaft 6 and blade installation shaft 7; Described power input shaft 6 and blade installation shaft 7 link by the cross coupler 8 that can slide vertically, offer vertically annular groove on blade installation shaft 7 and end face that power input shaft 6 is connected, and pressure spring 9 is installed in described annular groove; Be fixed with the annular abrasion-proof backing block 11 that the blade 10 with impeller assembly fits tightly at right end cap 3 inside faces, offer respectively intercommunicating pore on the upside of right end cap 3 and downside capping, described upper and lower intercommunicating pore is communicated with feeding cylinder 12 and discharge barrel 13 sealings respectively.
Described impeller assembly is fixedly set in right opening cylindrical shell 14 on the described blade installation shaft 7 by level vertically, and the external diameter of described right opening cylindrical shell 14 is less than the internal diameter of described barrel shell 1; The interval is fixed with a plurality of blades 10 vertically on the blade installation shaft 7 that is positioned at right opening cylindrical shell 14, and described a plurality of blades 10 are along the radially equal distribution of circumference, and each blade 10 all reverses 180 ° along the axle center axial screw of blade installation shaft 7; Like this, forms the also hopper 16 of screw twisted vertically of opening 15 by having formed the cross section between the inwall of right opening cylindrical shell 14 and the adjacent blades 10 for " V " font, right-hand member.
The utility model principle of work is summarized as follows:
When equipment operation, propulsion source ultromotivity input shaft 6 input torques rotate through cross coupler 8 impeller assemblies; Be communicated with feeding cylinder 12 in the time of directly over the opening 15 of impeller assembly right-hand member formation rotates to, material is in the dirty feed chute 16 of action of gravitation; Since by the cross section that forms between the inwall of right opening cylindrical shell 14 and the adjacent blades 10 for " V " font and vertically the right-end openings 15 of the hopper 16 of screw twisted fit tightly with annular abrasion-proof backing block 11, so form closed cavity and to have completely cut off external and internal pressure poor; When impeller assembly continue rotation so that the opening 15 that right-hand member forms rotate under the time be communicated with discharge barrel 13, material under action of gravitation from hopper 16 outflows.
Impeller assembly is in the rotary work process, owing to be subject to being installed in annular groove internal pressure spring 9 resilient force vertically, the impeller assembly right-hand member directly contacts all the time, fits tightly with annular abrasion-proof backing block 11, thereby eliminated gap between the two, greatly reduce the leakage of gas, play simultaneously the abrasion loss auto-compensation effect of contact surface between impeller assembly right-hand member and the annular abrasion-proof backing block 11, eliminate the gap that wearing and tearing produce, realize the function of auto-compensation.
The structure of the utility model impeller assembly is so that each hopper 16 forms independently obturator, and its sealing band only is the right-end openings 15 of hopper 16, has greatly reduced sealing band, has improved leak tightness.Abrasion-proof backing block 11 is chosen as high abrasion low-friction coefficient material, has improved the durability of equipment, has reduced rotational resistance, has reduced power consumption.
