Five, the specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.

Embodiment 1

A kind of cement mixer of present embodiment is with reference to figure 1, changing existing single barrel of formula structure is the twin-tub vertical structure, comprise the stirring cylinder 1 that constitutes by two tangent circular vertical buckets of parallel connection, stirring cylinder 1 top is provided with stirs bung 2, feeding port 17 is established the outside of bung 2 at one end, discharging opening 18 is located at the outside of another drum bottom, be equipped with respectively by top shaft support 3 each circular staving inside, the hollow shaft 5 of 4 fixed supports, 6, shaft support 3 is passed in its upper end, the cartridge housing 7 that 4 tops are set, 8 bearing inner sleeve stretches out on housing, peg graft with bucket bottom one alignment pin 11 in the lower end,

cartridge housing

Stirring cylinder 1 is made of two tangent circular vertical buckets of parallel connection, two barrels to have shape between tangent mutually identical, two dislocation passages of position opposite, channel height is high by 1/2 for not being higher than bucket, width is to be not more than 1/4 of barrel girth, two barrel of two outer tangent plane both sides respectively is provided with the rectangular slab that be used to seal and bucket is contour, both sides between two barrels form two subtriangular cavitys, this chamber communicates with two barrels of dislocation channel connection mouth places, and the bottom is one by base plate with two drums and delthyrial cavity envelope.

The course of work of this machine is: the feeding port 17 by stirring cylinder 1 top adds cement or other aggregate in bucket, start motor power, belt pulley 16 by motor 15

drives

5,6 rotations of two shafts, vortex

type stirring wing

12,13 on the

shaft

5,6 is started working simultaneously, because diameter pulley on two shafts is unequal, so the rotating speed that obtains on the diaxon is that differential stirs, and improved the agitation force to slurry, finish when stirring, obtain qualified slurry by discharging opening 18.

The utility model is compared with traditional cement mixer, has following characteristics:

1, changes the two modiolus of twin-tub into by in the past single barrel of single shaft, because the belt pulley on two shafts Diameter is unequal, and the rotating speed that therefore diaxon obtains when work is high speed, the low speed that does not wait Two kinds of rotating speeds, thus realized the variable speed stirring, be called again differential and stir, improved slurry Agitation force.

2, communicate owing to two barrels, when eddy current in the variable speed slurry rotates along the bucket outer, can exist Two delthyrial cavities form two little eddy current, and this eddy current direction and two barrels of eddy current are reverse, so shape again Become the eddy current differential, this eddy current has prolonged the glide path of slurry in two barrels, and has avoided The slurry that the does not stir discharge that takes a shorter way, thus make foaming machine obtain good slurry.

3, it is vertical that this mixer is designed to twin-tub, also solved the problem that pulp blender leaks, and prolongs Grow the service life of bearing, also solved traditional high-speed stirring owing to adopt the eddy current differential to stir in addition Mix the problem of spattering slurry, even cement mortar can not splash outside the bucket under the high-speed stirred state, thereby make yet The cement processing environment can keep clean does not have dirt.
