Abstract

The utility model discloses a mixing paddle device, comprising propeller blades and a main shaft which can be driven to rotate. The periphery of the main shaft is sheathed with a gear casing body, wherein, the propeller blades can be inserted into the gear casing body and rotate in radial direction around the main shaft in the gear casing body. The gear casing body is also provided with a locking mechanism, wherein, the locking mechanism can rotate and regulate the propeller blades when the locking mechanism is loose, and fix position between the propeller blades and the main shaft when the locking mechanism is tight. Therefore, the utility model can regulate the propeller blades to a required angle and further enable stirring intensity to be changeable so as to evenly stir, save energy and conveniently replace the propeller blades.

Description

A kind of paddle device

The utility model relates to mixing plant, relate in particular to a kind of paddle device.

At present, in the paddle device of the mixing plant that generally uses in production fields such as China's chemical industry, blade sheet majority is dull and stereotyped oar, palintrope turbine oar, enamel oar etc., and these paddle device consumed powers are big, all greater than 0.46KW/m ³And because blade sheet majority is directly to be fixed on the axle of paddle by modes such as welding or bolt, nuts, therefore the angle position of blade sheet is determined in design and production process, the blade sheet in use can't be regulated setting angle like this, the also angle that just can not regulate the blade sheet according to the variation of type that stirs material or quantity is to change the intensity that stirs; Published a piece of news on " southeast chemical information newspaper " in September 26 nineteen ninety-five, the product of maximum in the world design of fluid agitation equipment and manufactory---U.S. Lai Ning parent company " at North China pharmaceutical factory, Yizheng Fiber Optical plant ... and be widely used in the Baosteel wastewater treatment."; just at present Lai Ning company is at the product of China; compare with traditional paddle; its blade sheet is the variable cross-section form; under same mixing effect, and therefore the energy that the peaceful paddle of Lay can saves valuable be a kind of energy-conservation paddle; but the blade sheet is still on the axle that directly is fixed in paddle in the product of Lai Ning company, that is to say the intensity that in use can not change stirring by the setting angle of adjusting blade sheet.

The purpose of this utility model is to provide a kind of blade sheet use angle adjustable paddle device.

The utility model is realized by following proposal: a kind of paddle device, comprise a main shaft that can be driven in rotation and blade sheet, on the periphery of main shaft, be set with the wheel housing, be provided with the axis hole of the sharf that can insert the blade sheet in the wheel housing, and sharf can rotate in axis hole; Wheel is also installed a retaining mechanism on the housing, and this mechanism can rotate the sharf of regulating the blade sheet when loosening, can the fixed blades sheet when tight lock and main shaft between the position.

In the structure of above-mentioned paddle device, when becoming flexible retaining mechanism, angle by rotation moving blade axle, the blade sheet can be adjusted to and use needed angle, and then compress the pinning retaining mechanism with the fixed blades sheet, therefore this paddle Unit Installation angle can be regulated, and regulates efficient and convenient, and then make the stirring intensity of paddle device also can change thereupon, thereby reach stir energy-conservation; Adopt the paddle of this structure also comparatively convenient when changing the blade sheet in addition.

The utility model can be described in further detail by following drawings and embodiments.

Fig. 1 is the structural representation of first kind of embodiment of the utility model paddle device.

Fig. 2 is the broken section enlarged drawing of Fig. 1 paddle.

Fig. 3 is the structural representation of the another kind of embodiment of the utility model paddle device.

As Fig. 1, shown in Figure 2, a kind of paddle device, it comprises that one can be stirred the main shaft 4 of equipment Motor Drive rotation, the periphery of main shaft 4 is installed one and is taken turns housing 1, be provided with axis hole 5 on the periphery of wheel housing 1, the sharf 6 of blade sheet 3 is taper, it is inserted into axis hole 5, and can in axis hole 5, rotate, sharf 6 and wheel housing 1 usefulness one retaining mechanism 2 compress pinning, that adopt in the present embodiment is hat nut 2a and retainer ring 2c, and retainer ring 2c is fixed on the sharf 6, and hat nut 2a is radially taking turns on the housing 1 by thread set along main shaft 4, it can be from sharf 6 radially sharf 6 is compressed pinning, on the end face of hat nut 2a top stage 2d is arranged, can compress retainer ring 2c on the sharf 6, thereby axially sharf 6 is compressed pinning from sharf 6 by it; And in order to ensure blade sheet 3 and wheel the fastening degree between the housing 1, the locking back is locking with spot welding between hat nut 2a and wheel housing 1, this external hub body 1 is come of age has on the nut 2a periphery scale plate 7 can be used for the position of labeled leaf bobbin 6 rotations.

Shown in Figure 3 is the another kind of embodiment of the utility model, it is taken turns housing 1 and is divided into wheel housing 1a, lower whorl housing 1b, the upper and lower axis hole 5 that also can form the sharf 6 that inserts blade sheet 3 between housing 1a, the 1b of taking turns, retaining mechanism 2 is one to be installed in the axial nut 2b on the main shaft 4, locking axial nut 2b can clamp sharf 6, thus the position of fixed blades sheet 3; Loosening axial nut 2b can rotate the setting angle that moving blade axle 6 is regulated blade sheet 3; After the adjusting, screw axial nut 2b again, and spot welding is locking.

In the embodiment shown in Fig. 1, Fig. 3, blade sheet 3 can be dull and stereotyped oar, also can be variable cross-section formula paddle, as select variable cross-section formula paddle for use, and the stirring fluidised form when stirring is good, stirring is also more all even energy-conservation; Embodiment shown in Figure 1 can use under the bigger situation of stirring intensity, and embodiment shown in Figure 3 then can use under the less situation of stirring intensity.They can be widely used in the separation of liquid-solid, the solution-air, liquid-liquid etc. of industrial circles such as ore dressing, chemical industry, papermaking, food and pharmacy, as the extraction of solvent, neutralisation treatment, ore in sand form leaching and the vacuum crystallization etc. of waste water.
