Abstract

The utility model relates to an internal-external double-impeller combined stirring paddle, which is a machine used in a large-scale vertical kettle (pot) for stirring a plurality of liquid or liquid containing solid particles. The internal-external double-impeller combined stirring paddle which is provided by the utility model solves the problem that when the paddle is too long, the rigidity of the paddle is poor. A paddle diameter can be made considerably big, and at the same time, completely contrary (the same of different) forced flow of internal-external double layer of materials can be formed. Not only can the stirring effect be enhanced, but also the circular flow can be improved. The utility model has a good adaptability for the stirring of the liquid which is contained with the solid particles, and the specific gravity of the solid particles is higher or lower than the specific gravity of water, and the internal-external double-impeller combined stirring paddle has a good stirring action for mixed liquid with various specific gravities.

Description

The inside and outside box-like stirring arm of two pass vane group

The utility model relates to and a kind ofly is used for some kinds of liquid in the large-scale vertical still (jar) or contains the machinery that the liquid of solid particle stirs.

General paddle has only blade one, and blade is directly installed or is welded on the oar seat, blade be subjected to the influence of its rigidity and can not be made into quite long, the paddle diameter be restricted can not make quite big; Simultaneously, one oar can not make material form the inside and outside two-layer forced flow of (or identical) fully on the contrary vertically, so mixing effect and circular flow all are subjected to considerable influence.

The purpose of this utility model is to overcome the weak point in the above-mentioned technology, a kind of combined type paddle of inside and outside two pass blade is provided, it had both solved the rigidity difference problem that exists when blade is long, can form simultaneously the forced flow of inside and outside two-layer material fully opposite (or identical) again, both strengthen mixing effect, improved circular flow again.The utility model is achieved through the following technical solutions, and illustrates in conjunction with the accompanying drawings:

Oar seat 4 is made up of 2-3 semicircle cylindrical shell, is tightened to integral body with bolt 8 and nut 9; At the external cylindrical surface of oar seat 4, upper/lower terminal respectively has 3-4 to journal stirrup 12, the middle part 3-4 piece blade root plate 13 that is uniformly distributed along the circumference, and interior blade 3 usefulness screw bolt and nut are fastened on the blade root plate, oar in forming like this.Guide shell 2 is assembled into integral body by 3-4 piece smaller part cylinder by connecting plate 7 usefulness bolts 10 and nut 11.On the inner cylinder face of guide shell 2, be welded with 3-4 Connection Block 6, oar seat 4 and guide shell 2 are linked up by journal stirrup 12 with connecting rod 5, again outer blade 1 usefulness bolt 10, nut 11 are fixed on the guide shell 2, have so just formed the box-like paddle of inside and outside two pass vane group.Because connecting rod ratio of rigidity flat board is much better, so it can make long size, so the paddle diameter can be made enough greatly, this is the distinct advantages that it makes large-scale stirring; Secondly, interior road blade can be opposite fully with the inclination angle of outer course blade, and when paddle rotated, material can form inside and outside two plumes to opposite liquid stream, so can obtain good mixing effect, and big circular flow is arranged like this.Certainly, the inclination angle of interior road blade and outer course blade also can be identical, so just enlarged the mixing effect in the same way of paddle.

Claims

1. combined type paddle, form by oar seat (comprising cylinder, blade root plate and journal stirrup), inside and outside blade, guide shell, connecting rod, connecting plate, Connection Block and threaded connector, it is characterized in that blade divides inside and outside twice, interior road blade 3-4 sheet is contained on the oar seat, and outer course blade 3-8 sheet is installed on the guide shell.

2. combined type paddle according to claim 1 is characterized in that the incline direction of inside and outside twice blade can be identical, opposite or different.

3. combined type paddle according to claim 1, it is characterized in that the oar seat form by 2-3 semicircle cylindrical shell whole, its external cylindrical surface middle part 3-4 piece blade root plate that is uniformly distributed along the circumference, upper/lower terminal respectively has 3-4 to the journal stirrup that connecting rod is used is installed.

4. combined type paddle according to claim 1 is characterized in that guide shell is assembled into integral body by 3-4 piece semicircular cylinder, and the installing rack of the outer blade of conduct.

5. combined type paddle according to claim 1 is characterized in that oar seat and guide shell are coupled to whole paddle support with connecting rod.
