Abstract
The paddle that a kind of blade opening angle is adjustable, relate to a kind of paddle, described paddle is made up of shaft (1), tightening nuts (3), quill (4), blade (5), fixing buckle (7) and connecting rod (8), the lower end of shaft (1) is shaped with two protruding circles and fixes buckle (7), and the circular opening on blade snaps in the fixing buckle of shaft lower end fixing; The middle and upper part of shaft is shaped with screw thread (2), and quill (4) lower end is shaped with two protruding circles and fixes buckle, and quill (4) top and shaft are tightened by tightening nuts (3); The circular opening of connecting rod one end snaps on the fixing buckle of quill lower end, and other end circular opening snaps on the fixing buckle of mid blade.Connect quill and blade by connecting rod, blade is connected with shaft buckle, can be realized the adjustment of blade opening angle by lift quill.
Description
Technical field
The utility model relates to a kind of paddle, particularly relates to the paddle that a kind of blade opening angle is adjustable.
Background technology
In chemical field, chemical reaction is usually along with whipping process, and paddle is topmost stirring tool, for some specific chemical reaction, stirs whether fully directly affect reaction yield, and even directly whether impact test is successful.Current paddle is roughly divided into fixed blades and movable blade, the paddle of fixed blades is used in uncovered reaction vessel, if in closed reaction vessel, fixed blades spreading width need reduce diameter of propeller blade by the restriction of reaction vessel mouth neck, and thus stirring efficiency is lower.The paddle of moving paddle is used in closed reaction vessel, and during stirring, blade opens by centrifugal force, if for stir toughness material reactant in, the speed that reduces by half reduce, blade not easily opens, and affects mixing effect.
Summary of the invention
The purpose of this utility model is the paddle providing a kind of blade opening angle adjustable, and connect quill and blade by connecting rod, blade is connected with shaft buckle, can be realized the adjustment of blade opening angle by lift quill.
The purpose of this utility model is achieved through the following technical solutions:
The paddle that a kind of blade opening angle is adjustable, described paddle is made up of shaft, tightening nuts, quill, blade, fixing buckle and connecting rod, the lower end of shaft is shaped with two protruding circles and fixes buckle, two panels blade back is shaped with protruding circle to shaft one Middle face and fixes buckle, two panels blade has the circular opening fixed buckle with shaft lower end and match near shaft one end, the circular opening on blade snaps in the fixing buckle of shaft lower end fixing; The middle and upper part of shaft is shaped with screw thread, and quill is enclosed within outside shaft, and quill lower end is shaped with two protruding circles and fixes buckle, and quill top and shaft are tightened by tightening nuts; The two ends of two connecting rods have the circular opening matched with fixing buckle, and the circular opening of connecting rod one end snaps on the fixing buckle of quill lower end, and other end circular opening snaps on the fixing buckle of mid blade.
The paddle that described a kind of blade opening angle is adjustable, blade described in it is crab claw shapes, and it is shaped with gap.
The paddle that described a kind of blade opening angle is adjustable, mixes the front, lower end of axle and back side symmetry and is shaped with two protruding circles and fixes buckle described in it.
The paddle that described a kind of blade opening angle is adjustable, front, quill lower end described in it and back side symmetry are shaped with two protruding circles and fix buckle.
Advantage of the present utility model and effect are:
1, the utility model connecting rod connects quill and blade, and blade is connected with shaft buckle, can be realized the adjustment of blade opening angle, be tightened between quill and shaft by tightening nuts by lift quill.
2, the utility model blade is crab claw shapes, plays flow-disturbing effect, can reduce flow resistance in the material that stickiness is larger.
3, the utility model blade is shaped with gap, paddle overall weight can be reduced, reduce power of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
Annex in figure: 1 is shaft, 2 is screw thread, and 3 is tightening nuts, and 4 is quill, and 5 is blade, and 6 is gap, and 7 is fixing buckle, and 8 is connecting rod.
As shown in Figure 1, the utility model relates to the adjustable paddle of a kind of blade opening angle, described paddle is by shaft 1, tightening nuts 3, quill 4, blade 5, fixing buckle 7 and connecting rod 8 form, the front, lower end of shaft 1 and back side symmetry are shaped with protruding circle and fix buckle 7, two panels blade has the circular opening matched with fixing buckle near the side of shaft, circular opening on two panels blade is snapped in respectively in the fixing buckle of shaft lower end two symmetry, blade can around the rotation of 360 °, fixing buckle plane, two panels blade back is shaped with protruding circle to shaft one Middle face and fixes buckle.
The middle and upper part of shaft is shaped with screw thread 2, quill 4 is enclosed within outside shaft 1 and can moves up and down along shaft, front, quill 4 lower end and back side symmetry are shaped with protruding circle and fix buckle, shaft middle and upper part is shaped with screw thread 2, quill 4 top and shaft are tightened by tightening nuts 3, after unclamping tightening nut, quill can move up and down along shaft.The two ends, left and right of two connecting rods 8 have the circular opening matched with fixing buckle, and the circular opening of connecting rod one end snaps on the fixing buckle of quill lower end, and other end circular opening snaps on the fixing buckle of mid blade.Blade 5, in crab claw shape, it is shaped with gap 6, plays flow-disturbing effect, can reduce flow resistance in the material that stickiness is larger.
During use, unclamp tightening nuts, on carry quill, the angle in connecting rod and blade horizontal direction increases, when two blades are gathered to shaft center, paddle is inserted in the less reaction vessel of bore, then push away quill downwards, two blades are opened, take blade to when being opened to the angle of needs, screw tightening nuts, quill is fixed on shaft.Shaft top connects motor.
