Description

Stirring paddle of cantilever liquid stirring machine

Technical Field

The utility model relates to a cantilever liquid mixer's part, especially a cantilever liquid mixer's stirring rake.

Background

The cantilever liquid agitator is also called an overhead agitator, an electric agitator or a mechanical agitator, can perform liquid-liquid mixing, solid-liquid suspension, gas-liquid or liquid-liquid dispersion and the like, is suitable for agitating various solutions, reagents and the like with certain viscosity, is an instrument mainly applied to the circulation of uniform mixing, homogenization, suspension, injected gas and high-viscosity substances, and is widely applied to the fields of chemical and petroleum applications, beverage production, dairy production, food processing, sugar and candy production, ceramic applications, water treatment, cosmetic production, colorant and paint production, paper making and the like. The stirring paddle of the existing cantilever liquid stirring machine is generally divided into an upper shaft section and a lower shaft section, the upper shaft section is connected with a power device, the lower shaft section is connected with a stirring paddle blade, and the stirring paddle blade needs to be cleaned and replaced frequently, so that the stirring shaft is generally designed into a power shaft and a paddle blade shaft which are separated from each other, and when the stirring paddle is used, the stirring paddle and the power shaft are connected in a certain connection mode for use.

The existing connection mode of the stirring paddle is bolt connection, as shown in fig. 1, a connection flange 301 protruding outwards is arranged at the tail end of an upper connection section and the top end of a lower connection section of the stirring paddle, the flange 301 is connected after the semi-circular left and right two half-sheet hoops 302 are closed, and the closed parts of the hoops 302 are connected by bolts 303. The connection mode at least needs two persons to operate, the operation is complicated, one operator needs to hold the upper section and the lower section of the stirring paddle by two hands respectively due to the fact that the stirring paddle is heavy, the other operator holds the hoop 302 and the bolt 303 by the hands, and the bolt is screwed by the screwdriver. Because cantilever type mixer's stirring rake need insert the inside stirring operation that carries out of liquid container from the eminence, the stirring rake junction is far away from operator's position, screws up the bolt and not only wastes time and energy, and the bolt falls into liquid inside easily moreover, brings the influence for stirring work. Secondly, because the junction flange is connected with the mode that two staple bolts fold, the staple bolt is not flexible, and it can not hug closely completely with the stirring rake junction, and the junction has the clearance, produces the dislocation easily between power shaft and the paddle axle, makes the center pin of stirring rake produce the skew, and the (mixing) shaft produces easily and rocks in the stirring process, influences the stirring effect.

SUMMERY OF THE UTILITY MODEL

To above not enough, the utility model provides a cantilever liquid mixer's stirring rake, the power shaft on its upper portion and the paddle axle of lower part are connected in order to collude the mode of hanging, and the installation is convenient high-efficient with the dismantlement, and one can operate, improves connection efficiency.

The technical scheme of the utility model is that:

the stirring paddle of the cantilever liquid stirring machine comprises a power shaft and a paddle shaft, wherein the lower end part of the power shaft is a hook-shaped connecting part, the upper end part of the paddle shaft is a barb-shaped connecting part matched with the hook-shaped connecting part, and the power shaft and the paddle shaft are connected with each other in a hooking mode.

And a fixed shaft sleeve is sleeved outside the connecting part of the power shaft and the paddle shaft, and the inner diameter of the fixed shaft sleeve is equal to the outer diameter of the connecting part.

The barb-shaped connecting part of the paddle shaft is provided with a falling-stopping step protruding outwards.

The utility model discloses a cantilever liquid mixer's stirring rake is including being located the power shaft on upper portion and the paddle axle that is located the lower part, and connecting portion between them are hook-like connecting portion to the mode hookup that colludes each other. The outside cover of connecting portion has fixed axle sleeve, and fixed axle sleeve internal diameter equals the connecting portion external diameter, prevents that connecting portion dislocation from droing, and firm in connection is reliable. The connecting part is convenient to clean and has no dead angle. Under this kind of connected mode, the center pin of stirring rake keeps on a straight line, can not produce the skew, and the rotatory in-process center pin of stirring rake can not produce and rock, and the stirring is stable high-efficient. The connection can be operated by a single person, the connection process can be completed without any screw fixation and tools.

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.

Referring to fig. 2-4, the stirring paddle of the cantilever liquid stirring machine of the present invention comprises a power shaft 10 and a blade shaft 20, wherein the lower end of the power shaft 10 is a hook-shaped connecting portion 11, and the upper end of the blade shaft 20 is a barb-shaped connecting portion 21 adapted to the hook-shaped connecting portion 11. In order to prevent the connection part from being dislocated and falling off, a fixed shaft sleeve 22 is sleeved outside the connection part, and the inner diameter of the fixed shaft sleeve 22 is equal to the outer diameter of the connection part. In order to prevent the fixed bushing 22 from slipping off, the barb-like connection 21 of the blade shaft 20 is provided with an outwardly projecting drop stop step 23.

When the stirring paddle is used, the fixed shaft sleeve 22 is sleeved on the power shaft 10 from bottom to top, the hook-shaped connecting part 11 of the power shaft 10 is hooked with the barb-shaped connecting part 21 of the paddle shaft 20, and the fixed shaft sleeve 22 is pushed down to fall on the protruding falling stopping step 23 to complete the connection of the stirring paddle. The utility model discloses a cantilever liquid mixer's stirring rake need not any screw fixation when connecting, need not with the help of the instrument, single can accomplish, and firm in connection is reliable. The connecting part is convenient to clean and has no dead angle. Under this kind of connected mode, the center pin of stirring rake keeps on a straight line, can not produce the skew, and the center pin can not produce when the stirring rake is rotatory and rock, and the stirring is stable high-efficient.
