Abstract
The invention discloses a filter unit for polyurethane resin. The filter unit comprises a reaction vessel, a filter and a storage container. The upper part of the reaction vessel is provided with a feed inlet, and the lower part of the reaction vessel is provided with a discharge port. The discharge port is connected to the filter through a first pipeline. The storage container is connected to the filter through a second pipeline. A stirring device is arranged inside the reaction vessel. The stirring device contains a first mixer shaft and a second mixer shaft, which are parallelly and vertically arranged inside the reaction vessel. The first mixer shaft and the second mixer shaft are connected with upper and lower pairs of mixing vanes. The mixing vanes in each pair are symmetrically distributed, and the upper and lower pairs of mixing vanes are symmetrically distributed. By connecting the reaction vessel with the filter and additionally arranging related conveying piping strainers, without influencing flow of polyurethane resin, impurities are further filtered out, packaging efficiency is enhanced, and production cost is reduced. By the additional arrangement of the mixer shafts, the shape of a traditional mixer shaft is changed, stirring force is increased, and impurities are reduced from the source.
Description
Technical field
The present invention relates to a kind of packaging system, more particularly to a kind of polyurethane resin defecator, belong to polyurethane resin packaging facilities field.
Background technology
Polyurethane full name is polyurethanes, is containing the general designation of the macromolecular compound for repeating carbamate groups on main chain.It is outer on polyurethane Shi Zi China carbamate also to introduce group containing ether-ether urea biuret urea groups elder generation polyurethane behind sea.It is formed with dihydroxy or polyol addition polymerization by organic diisocyanate or polyisocyanates.Polyurethane material, purposes is very wide, can replace rubber, plastics, nylon etc., for airport, hotel, building materials, automobile factory, colliery factory, cement plant, condo, villa, landscaping, colored stone art, park etc..
General, polyurethane is the polymer by made by polyisocyanates and the raw material such as polyether polyol or the chain extender such as PEPA and/or small molecule polyol, polyamine or water or cross-linking agent, then completely reacted polyurethane resin needs are transferred to into container from reactor to be packed, it is uneven due to there is stirring in course of reaction, polyurethane resin solution is caused to there may be the larger urethane resin particles of molecular weight, thus before packing, need to remove impurity through filtration step.
At present, existing polyurethane resin defecator is that a reactor is equipped with a filter, increased production cost；And filter screen is single filter screen in filter, area is larger, is easily damaged when using.
In addition to considering to add defecator, it is also that solve problem needs a factor of consideration to improve stirring dynamics and mixing effect, after only both resolving, could improve packaging efficiency, reduces production cost.
The content of the invention
It is an object of the invention to provide a kind of polyurethane resin defecator, to solve the still unsolved difficult problem of above-mentioned prior art.
The technical solution used in the present invention is：A kind of polyurethane resin defecator, including reactor, filter and storage container, it is characterised in that：The reactor top is provided with charging aperture, and lower section is provided with discharging opening, and discharging opening is connected with filter by the first pipeline；The storage container is connected by second pipe with filter；The reactor is internally provided with agitating device；The agitating device includes the first shaft and the second shaft, and the first shaft and the second shaft are vertically installed in side by side inside reactor；Upper and lower two pairs of paddles are respectively fixedly connected with first shaft and the second shaft, each pair paddle is symmetrical, upper and lower two pairs of paddles are symmetrical.
Further, distance is 3～6cm between first shaft and two pairs of paddles of the second shaft.
Further, first shaft and the second shaft are the first shaft in opposite direction and the second shaft for rotating.
Further, it is provided with filter screen on first pipeline.
Further, the aperture of the filter screen is 120～150mm.
Further, the number of the reactor is 1～3.
Beneficial effect：The present invention connects filter by the reactor for adopting, and increases related conveyance conduit filter screen, under the traffic conditions for not affecting polyurethane resin, has also further filtered impurity, improves product purity and packaging efficiency, reduces production cost；Apparatus of the present invention increased shaft, change the shape of traditional shaft, improve stirring dynamics and mixing effect, and the generation of impurity is reduced from source.
Description of the drawings
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is the overall schematic of polyurethane resin defecator of the present invention.
Specific embodiment
A kind of polyurethane resin defecator, including reactor a1 and reactor b9, filter 10 and storage container 12, reactor a1 tops are provided with charging aperture 15, and lower section is provided with discharging opening 14, discharging opening 14 is connected with filter 10 by the first pipeline 8, and on the first pipeline 8 filter screen 7 is provided with；Storage container 12 is connected by second pipe 11 with filter 10；Reactor a1 is internally provided with agitating device；
Agitating device includes the first shaft 2 and the second shaft 5, and the first shaft 2 and the second shaft 5 are vertically installed in side by side inside reactor a1；First shaft 2 is fixedly connected with paddle 3 and first time paddle 6 on first, and paddle 4 and second time paddle 15 on second are connected with the second shaft 5, and each pair paddle is symmetrical, and upper paddle and lower paddle are symmetrical.
The interior arrangement of reactor b9 is consistent with reactor a1.
The above is the preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this.It should be pointed out that for those skilled in the art, technical scheme is modified or equivalent, without departure from protection scope of the present invention.
