Abstract
The utility model relates to the technical field of stirring equipment, and in particular relates to a stirring device for stirring cellulose. The stirring device comprises a stirring shaft, wherein an inner helical ribbon is fixedly arranged on the stirring shaft; a plurality of support rods are transversely arranged on the stirring shaft; every two adjacent support rods are staggered in the radial direction of the stirring shaft; an outer helical ribbon is fixedly arranged on the support rods, surrounds the stirring shaft, and is positioned on the periphery of the inner helical ribbon; the helical direction of the inner helical ribbon is opposite to that of the outer helical ribbon. According to the stirring device, the inner and outer helical ribbons drive feed liquid to move in opposite directions when the stirring shaft rotates, so that the feed liquid can be fully mixed for multiple turns, and the dissolution speed of the cellulose is increased; the support rods which are staggered in the radial direction of the stirring shaft are arranged on the stirring shaft, and are used for fixing the outer helical ribbon, so that the strength of the outer helical ribbon is strengthened, deformation or displacement after long-time use can be avoided, stirring effects are ensured, and the working stability of the device is enhanced; moreover, the support rods have a function of mixing the feed liquid in a horizontal shearing way, so that stirring and mixing effects are enhanced.
Description
Technical field
The utility model relates to mixing plant technical field, relates in particular to a kind of agitating device for dissolving cellulos.
Background technology
Disappearing fibre is a kind of first dissolving cellulos pulp, then the regenerated celulose fibre making by dry-wet spinning, is described as 21st century green fiber.It adopts enclosed dissolving, spinning, solvent recovery process, technique is brief, cellulosic material environmental protection used, N-methylmorpholine-N-oxide solvent used is nontoxic recyclable, the disappearing fibre making has the two-fold advantage of synthetic fibers and natural fiber concurrently, once realize large-scale production, will probably replace the viscose rayon of high pollution.
But cellulose solution viscosity is larger, very high to agitating device requirement, conventional agitating device cannot make it mix fully, and the feed liquid stirring easily produces bubble, brings difficulty to spinning solution deaeration.Mainly apply at present ribbon agitating mode, on shaft, be provided with internal layer ribbon and outer ribbon, the hand of spiral of internal layer ribbon and outer ribbon is contrary, and when shaft rotates, it is contrary with the moving direction that outer ribbon promotes feed liquid that internal layer ribbon promotes internal layer feed liquid, feed liquid is mixed, because solution viscosity is larger, the force rate that ribbon is subject to is larger, and a lot of agitating devices are after using a period of time, outer ribbon can deform or be mobile, the effect that impact is uniformly mixed.
Utility model content
The purpose of this utility model is to provide a kind of agitating device for dissolving cellulos, and the helix stirring device outer ribbon after using a period of time that is intended to solve prior art can deform or movement, thereby affects the technical problem of stirring and mixing effect.
The utility model is to realize like this, a kind of agitating device for dissolving cellulos, comprise shaft, on described shaft, be fixed with interior ribbon, on described shaft, be laterally provided with some support bars, adjacent described support bar described shaft radially on be crisscross arranged, on described support bar, be installed with outer ribbon, described outer ribbon is around described shaft setting and be positioned at described ribbon periphery, and the rotation direction of described interior ribbon and outer ribbon is contrary.
As a kind of improvement, described support bar described shaft axially on be uniformly distributed and vertical with described shaft, the bearing of trend of adjacent described support bar is mutually vertical.
As improving further, on described shaft, be arranged with shaft sleeve pipe, described shaft sleeve pipe and shaft fixedly removably connect, and described interior ribbon and support bar are all fixed on described shaft sleeve pipe.
As improving further, described shaft and shaft sleeve pipe link together by steady pin.
As improving further, described interior ribbon is provided with one, and described outer ribbon is provided with two.
Owing to adopting technique scheme, the beneficial effects of the utility model are: owing to being fixed with interior ribbon on shaft, in interior ribbon periphery, be fixed with outer ribbon, and interior ribbon is contrary with the rotation direction of outer ribbon, when shaft rotates, interior ribbon and outer ribbon promote the opposite direction that feed liquid moves, be convenient to feed liquid and carry out the abundant mixing of many bouts, improve cellulosic dissolution velocity, by the some support bars that make progress interlaced arrangement in shaft footpath of horizontally set on shaft, fix outer ribbon, strengthened the intensity of outer ribbon, after long-time use, also can not be out of shape or displacement, guarantee mixing effect, the stability of intensifier work, preferably, support bar is uniformly distributed on axially at shaft and perpendicular to shaft, the bearing of trend of adjacent supports bar is mutually vertical, support the effective of fixing outer ribbon, and the effect that has horizontal shear to mix to feed liquid, strengthened the effect being uniformly mixed.
Owing to being arranged with shaft sleeve pipe on shaft, shaft sleeve pipe and shaft fixedly removably connect, interior ribbon and support bar are all fixed on shaft sleeve pipe, shaft sleeve pipe can be dismantled from shaft, be convenient to maintenance or change interior ribbon and outer ribbon, preferably, shaft sleeve pipe removably connects by steady pin and shaft, simple in structure, good fixing effect, convenient disassembly.
Because interior ribbon is provided with one, outer ribbon is provided with two, simple in structure, and mixing effect is good, can adapt to stirring demand.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Wherein: 1-shaft, ribbon in 2-, 3-support bar, the outer ribbon of 4-, 5-shaft sleeve pipe, 6-steady pin.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of agitating device for dissolving cellulos, comprise shaft 1, on this shaft 1, be fixed with interior ribbon 2, on shaft 1, be laterally provided with some support bars 3, adjacent supports bar 3 is crisscross arranged on radially at shaft 1, on support bar 3, be installed with outer ribbon 4, outer ribbon 4 is around shaft 1 setting and be positioned at ribbon 2 peripheries, the rotation direction of interior ribbon 2 and outer ribbon 4 is contrary, adjacent supports bar 3 interlaced arrangement, fix better outer ribbon 4, strengthened the intensity of outer ribbon 4, avoid device after long-time use, outer ribbon 4 deforms or displacement and affect mixing effect, strengthened the job stability of device, and support bar 3 also produces to stirring feed liquid the effect that horizontal shear is mixed, strengthened the effect being uniformly mixed, particularly, support bar 3 is uniformly distributed and is vertical with shaft 1 on shaft 1 is axial, the bearing of trend of adjacent supports bar 3 is mutually vertical, simple in structure, fix the effective of outer ribbon 4.
