Abstract
The utility model relates to ventilation dust removing and pneumatic conveying system equipment, in particular to an air lock with arc blades, which comprises a casing. An impeller is installed inside the casing, end covers are arranged at two ends of the casing relative to the impeller, an impeller shaft extends out of the end covers, a plurality of blades are installed on the impeller shaft, and flanges are further welded at two ends of the impeller. The air lock is characterized in that the arc blades are orthogonal to the impeller shaft. The air lock solves the problems of easy material accumulation at two ends of each blade, increased running resistance, reduced yield and increased energy consumption due to the fact that the corners and edges are easy to suspend crudes, even motor burnout due to blockage and the like of existing air locks, and can be widely used for conveying systems in grain processing industry, feed processing industry, pharmaceutical industry, chemical industry, cigarette industry, cement industry and the like.
Description
(1) technical field: the utility model relates to dust removal by ventilation and strength delivery system device, especially a kind of arc shaped blade air sealer.Be widely used in the delivery system of industries such as grain processing, feed processing, medicine, chemical industry, tobacco, cement.
(2) background technology: well-known traditional air sealer is that close gas is finished in the gap of outer shell and impeller maintenance and row unloads material.The most tangible drawback one of the air sealer in past: the impeller of manufacturing cylinder iron is not only stupid but also heavy.Its two: impeller mostly is the blade that adopts plane or inclined plane shape, the easy buildup in two ends, the corner hangs coarse fodder again and blocks up and burn out motor.Its three: reduce the output growth energy consumption because buildup or bridging have increased air sealer running frictional resistance.
(3) summary of the invention: the purpose of this utility model will overcome the easy buildup in existing air sealer blade two ends exactly, the corner hangs coarse fodder easily, causes the air sealer running resistance to increase, and reduces the output growth energy consumption, even traffic congestion burns out the problem of motor, and a kind of arc shaped blade air sealer is provided.
Concrete scheme of the present utility model is: improve at existing air sealer, it has housing, impeller is housed in the housing, the relative impeller in housing two ends is provided with end cap, paddle shaft stretches out the end cap outside, and some blades are installed on the paddle shaft, the impeller two ends flanged plate that also has been welded, it is characterized in that: described blade is an arc, with the paddle shaft quadrature.
Blade described in the utility model adopts the attaching parts butt joint to form by two sections, changes to make things convenient for wearing and tearing back, blade outer end, and need not change impeller.
For the better disadvantage that solves the serious buildup in impeller two ends, improve anti-blocking performance, the flanged plate external diameter at the two ends of impeller described in the utility model is 1/3 of a blade external diameter, and the flanged plate outer face at described impeller two ends is concordant with the blade two ends respectively.
The utility model has been owing to adopted arc shaped blade, the radial mechanical angle when both having changed impeller operation, and the axial friction when having alleviated impeller operation again, thus reduced energy consumption.Arc shaped blade adopts moulded section simultaneously, strengthened the resistance to bending of steel plate widely, thereby long-term operation can not change airtight performance.And row unloaded in the middle of the material of random sedimentation belonged to blade during arc shaped blade can be kept watch and be netted, impeller two ends flanged plate shortens and reduces back (originally the flanged plate external diameter equates with the blade external diameter) in addition, solved the disadvantage of the serious buildups in air sealer two ends, improve anti-blocking serviceability, also reduced energy consumption.
The utlity model has following characteristics:
1, the wearer of no caulking gum is to the pollution of edible material;
2, blade bending resistance modification not, airtight performance is stable;
3, the leftover bits and pieces of material of work material is few;
4, the no backup operation friction reduces in the machine, and energy consumption is low;
Radial angle changes when 5, moving, the tangential force buffering, and anti-blocking performance is good;
6, maintenance and replacing blade are convenient, long service life.

Among the figure: 1-housing, 2-end cap, 3-paddle shaft, 4-primary blades, 5-outer leafs, 6-bolt, 7-flanged plate.
(5) specific embodiment:
Referring to Fig. 1 Fig. 2, the utlity model has housing 1, impeller (comprising paddle shaft 3 and blade) is housed in the housing 1, the relative impeller in housing 1 two ends is provided with end cap 2, and paddle shaft 3 stretches out end cap 2 outsides, and six blades are installed on the paddle shaft 3, the impeller two ends flanged plate 7 that also has been welded, referring to Fig. 3, particularly: described blade is arc (referring to Fig. 5,6), with paddle shaft 3 quadratures.And blade is to adopt bolt 6 butt joints to form (outer leafs 5 has identical arc with primary blades 4) by 5 two sections of primary blades 4 and outer leafs, referring to Fig. 3,4.Flanged plate 7 external diameters at described impeller two ends are 1/3 of blade external diameter, and flanged plate 7 outer faces at described impeller two ends are concordant with the blade two ends respectively.Promptly constitute the utility model.
Claims (4)
