Description

Non-helical reciprocal gyratory shaker

Technical field:

The utility model is relevant with mixer, and is special relevant with non-helical reciprocal gyratory shaker.

Background technology:

The even mixing of various solid, solid phases, solid-liquid phase substance is the needed technical process of a lot of suitability for industrialized production, all uses various mixers to go to finish usually.The efficient of hybrid working and the uniformity coefficient that can reach are the basic mechanical design feature indexs of mixer.Mixer commonly used has paddle formula, screw rod or helical-ribbon type, worm-gear type, bent-arm etc.Existing a kind of reciprocal spiral mixer such as Fig. 5～shown in Figure 7, belong to the whipped form that a kind of high efficiency also can be carried out self-cleaning.This mixer is made up of the mixing drum 9 and the shaft 8 of cylinder type, settles a cover single head hurricane band on shaft 8, and (per 120 °) are disconnected opens a gap at circumference 1/3rd places, form three row's helical blades 10.In columnar mixing drum 9, be positioned to the cleaning pin 11 that helix is arranged, the pitch L that cleaning pin 11 is arranged ₂Pitch L with helical blade ₁Equate that distributing remains 120 ° on circumference, form three rows.Shaft 8 whenever rotates a circle, a reciprocal stroke L ₃, helical blade 10 is walked around two cleaning pins 11 and is got back to the original place.The starting point of stroke and terminal point are all on the room between the cleaning pin 11.Stroke distances L ₃Less than the distance L between two cleaning pins ₂, L ₃=2/3L ₂But shear strength, stirring efficiency that this mixer stirs material, the degree that stirs need further to improve.

The utility model content:

The purpose of this utility model is in order to overcome above deficiency, to provide a kind of and can strengthen the shear strength that material is stirred, improving the non-helical reciprocal gyratory shaker of the uniformity coefficient of stirring efficiency and stirring.

The purpose of this utility model is achieved like this:

The non-helical reciprocal gyratory shaker of the utility model, comprise motor, be subjected to motor-operated reciprocal revolving power mechanism, mixing drum, the shaft that an end that is positioned at mixing drum is connected with reciprocal revolving power mechanism, it is characterized in that having on the shaft the oblique blade of the three row oblique angles distributions of arranging vertically, become 120 ° of angles between the oblique blade of three rows, tiltedly blade is distributed on the shaft same section radially, on the mixing drum inwall, be distributed with along the mixing drum axially-aligned and with oblique blade staggered three clear the reason pin, three clear 120 ° of angles of one-tenth between the reason pin, and the cleaning pin is distributed on the radially same section of mixing drum inwall.

Above-mentioned adjacent oblique interlobate axial distance L ₁And the axial distance L between adjacent cleaning pin ₂Equate that tiltedly blade is distributed on the same section, does not form continuous helix, the cleaning pin is distributed on the same section, does not form the continuous helical line.

Above-mentioned reciprocal revolving power mechanism comprise the spur bevel gear that is connected with motor by decelerator and symmetry output and with the eccentric disc of reciprocating power transmission and shaft, shaft and the output shaft on the spur bevel gear coaxial fuse synchronous to realize back and forth rotating, the eccentric throw L of eccentric disc ₁With a reciprocal stroke L of shaft ₃Equate.

The utility model is compared with existing reciprocal spiral mixer, and the firstth, reciprocating stroke strengthens 1/3rd; The secondth, the ratio of reciprocal time and number of revolutions improves 1/3rd; The 3rd is that blade improves 1/3rd with the relative motion probability of clearing up pin.More than 3 strengthened the shear strengths that material is stirred, improved stirring efficiency, and the uniformity coefficient that stirs.

The specific embodiment:

Referring to Fig. 1～Fig. 4, reciprocating power rotating mechanism 1 passes to motor 12 moments on the power transmission shaft 3 by reductor 2.Symmetry is equipped with eccentric disc 4 and makes shaft 8 reciprocating on the power transmission shaft 3.Spur bevel gear 5 and spur bevel gear 6 engagements that are contained on the power transmission shaft 3 are equipped with output shaft 7 on the spur bevel gear 5.Shaft 8 is positioned at mixing drum 9 and stretches out on the outer end of tube and output shaft 7 coaxial linking into an integrated entity.After spur bevel gear slows down with 2: 3 speed ratios with rotary power transmission and shaft 8.Have the oblique blade 10, three of the three row oblique angles layouts of arranging vertically to arrange 120 ° of angles of one-tenth between oblique blade on the shaft 8, the axial distance between the adjacent oblique blade 10 is L ₁, tiltedly blade 10 is distributed on the same section of shaft radial axle, does not form continuous helix.Three clearing reason pin 11, three and clear between the reason pin and become 120 ° of angles, the axial spacing L between the adjacent cleaning pin 11 of arranging is installed in columnar mixing drum 9 vertically ₂And the axial distance L between the oblique blade 10 ₁Equate.Cleaning pin 11 is distributed on the mixing drum same section radially, does not form continuous helix.

Back and forth revolving power mechanism is the eccentric disc 4 that passes to spur bevel gear 5 and symmetry output by reductor respectively.Right angle conical gear 5 passes to shaft 8 with rotary power after slowing down by 2: 3 speed ratios, and eccentric disc 4 passes to shaft 8 with reciprocating power, the eccentric throw L of eccentric disc 4 ₄Equal a reciprocal stroke L of shaft ₃, on shaft 8, obtaining synthetic synchronously reciprocal rotary power, every stroke shaft 8 anglecs of rotation once are 240 ° and have satisfied and stir

Mix the motion requirement of the stirring executing agency of tube and shaft composition.In 8 every 2/3rds weeks of rotation of shaft, reciprocating stroke once.Tiltedly blade 10 is walked around a cleaning pin 11, gets back to original section, does not get back to the original place, but gets back on 240 ° the phase place.Still on the room between the cleaning pin 11, the distance of stroke is L for the starting point of stroke and terminal point ₃, equal two distance L between the cleaning pin 11 ₂
