Abstract
A static-state mixing apparatus used in a preparation process of bi-component polyurea. The static-state mixing apparatus comprises two material storage barrels which are connected to a power output terminal of a plunger pump through feeding pipelines. The feeding pipelines are provided with feeding valves. The power output terminal of the plunger pump is also connected to a material inlet of a static-state mixing tube through a material discharging pipeline. The material discharging pipeline is provided with a material discharging valve. A plunger push rod is arranged on the plunger pump. In a preparation process of a bi-component polyurea material in the prior art, problems of disproportionality, non-uniform mixing and construction time being too long exist. In the static-state mixing apparatus, when being used for mixing and preparing the bi-component polyurea material, the synchronous plunger pump drives the bi-component polyurea material to be mixed in the static-state mixing tube so that the bi-component polyurea material is uniformly prepared according to proportion, thereby ensuring proportions of different components in the bi-component polyurea material to be mixed stably and uniformly and saving operation time.
Description
Technical field
The present invention relates to the preparation system of two-component polyurea, refer to a kind of static mixing device for two-component polyurea preparation process particularly.
Background technology
In Middle Line Project For Transferring Water From South To North Open Channel Construction engineering, in order to improve the security of high roadbed canal section, Concrete Lining of Canals plate parting position, local needs brushing polyurea elastic material, oozes control means to strengthen channel.Conventional polyurea materials is bicomponent material, and adopt spraying coating process to construct, after mixing, reaction is very fast, generally will solidify within the time of several seconds.In order to improve the binding ability of polyurea materials and concrete surface, by adjustment material component, suitably reduce polyurea materials reaction speed, the material reaction time reaches 10 ~ 20 minutes, adopts and manually carries out knife-coat application.Human configuration is adopted to have several shortcoming when the long response time polyureas of bi-component is constructed: 1, the ratio of manual weighing is wayward, easily occurs two kinds of component ratio offset influence material performance indexs; 2, artificial mixing is uneven, affects material property; 3, the time of material operable is shorter, adopts artificial mixing mixing to need to consume the longer time, shortens the operable time of material construction, cause material blade coating uneven.
Summary of the invention
The object of the invention is to the weak point overcoming above-mentioned existing background technology, and a kind of static mixing device for two-component polyurea preparation process is provided, adopt two synchronous plunger displacement pumps to carry out static mixing to two-component polyurea material, solve out of proportion, incomplete mixing in two-component polyurea material preparation process and engineering time long problem.
The object of the invention is to reach by following technical solution: for the static mixing device of two-component polyurea preparation process, it comprises two storage vats, described storage vat is connected with plunger displacement pump clutch end by feed pipe, described feed pipe is provided with inlet valve, described plunger displacement pump clutch end is also connected with the feeding mouth of static mixing tube by discharge nozzle, described discharge nozzle is provided with outlet valve, and described plunger displacement pump is provided with plunger stem.
Preferably, described plunger stem is synchronous double plunger push rod, synchronous by connecting guarantee two plunger displacement pumps respectively with two plunger displacement pumps.
Further, described static mixing tube is 16 ~ 18 joints, and length is 160 ~ 250mm, and the discharging opening of mixing tube (5) is 3.5mm.To ensure that raw material mixes, discharging is even.
When the present invention is used for being mixed with of two-component polyurea material, drive two-component polyurea material in the mixing of static mixing tube by synchronous plunger displacement pump, two-component polyurea material is proportionally evenly configured, ensure that the stablizing of different component ratio in two-component polyurea material, mix, and save construction operation time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figure 1, the present invention includes two storage vats 1, storage vat 1 is connected with plunger displacement pump 3 clutch end by feed pipe 2, feed pipe 2 is provided with inlet valve 6, feed time is controlled by inlet valve, plunger displacement pump 3 clutch end is also connected with the feeding mouth of static mixing tube 5 by discharge nozzle 4, and discharge nozzle 4 is provided with outlet valve 8, and plunger displacement pump 3 is provided with plunger stem 7.
Wherein, plunger stem 7 is synchronous double plunger push rod, synchronous by connecting guarantee two plunger displacement pumps respectively with two plunger displacement pumps.The volume ratio that the plunger case internal diameter of plunger displacement pump 3 forms according to material is selected, volume ratio is that the bicomponent material of 1:1 selects two identical plunger displacement pumps 3 synchronously to drive the synchronous material discharging that can realize same volume material, and the bicomponent material for other ratios selects the plunger displacement pump of different cylinder diameters can realize synchronous material discharging in proportion according to ratio.In addition, static mixing tube 5 is 16 ~ 18 joints, and length is 160 ~ 250mm, and the discharging opening 51 of mixing tube 5 is 3.5mm.To ensure that raw material mixes, discharging is even.
By the A of two-component polyurea, B two kinds of raw materials are respectively charged in two storage vats 1, the plunger stem 7 of plunger displacement pump 3 is pushed into front end, close outlet valve 8, open inlet valve 6, the plunger stem 7 of plunger displacement pump 3 can slowly retreat, A, namely B two kinds of raw materials flow in plunger displacement pump 3 cylinder body by feed pipe 2, inlet valve 6 is closed after plunger stem 7 is pushed into tail end, open outlet valve 8 again, by the plunger stem 7 slowly forward impelling of plunger displacement pump 3, plunger stem 7 can by A, B two kinds of raw materials are synchronously pushed into static mixing tube 5, through repeatedly two points of stirrings of static mixing tube 5, the A of two-component polyurea, B two raw material mix from discharging opening 51 discharging.
Other unspecified part is prior art.
