Detailed description of the invention
In order to understand the present invention better, explain embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, in figure, tank body 1, safety valve 2, threeway 3, capsule air bleeding valve 4, tank body air bleeding valve 5, go out hydraulic control valve 6, proportioner 7, water inlet control valve 8, capsule 9, antipriming pipe 10, check-valves 11, tapping valve 12, draining valve 13, inlet pipeline 14, fluid pipeline 15
A kind of foam solution pressure type proportion mixing device, comprise tank body 1, capsule 9 is provided with in tank body, it is interlayer between tank body 1 and capsule 9, tank body 1 top is provided with threeway 3 valve be connected with tank inner chamber, tank body 1 bottom is provided with tapping valve 12, draining valve 13, wherein tapping valve 12 is connected with tank base Drainage pipe, draining valve 13 is connected with tank base drainage pipeline, described threeway 3 by fluid pipeline 15 with go out hydraulic control valve 6 top and be connected, go out hydraulic control valve 6 bottom to be connected with proportioner 7 top, proportioner 7 is provided with the water inlet end of level, water side, be connected with water inlet control valve 8 top bottom proportioner 7 in addition, water inlet control valve 8 bottom is connected with inlet pipeline 14, described inlet pipeline 14 is communicated with interlayer by the opening on tank body 1, antipriming pipe 10 is provided with in tank body, on antipriming pipe 10 wall along the circumferential direction and be axially arranged with and discharge fluid apertures more, described antipriming pipe 10 passes perpendicularly through the inner chamber of capsule, the upper end of antipriming pipe 10 and the upper end inner hole of capsule, the lower end inner hole of lower end and capsule, the upper end cylindrical of capsule, lower end cylindrical respectively with the inner hole of the upper and lower side of tank body, the bottom of described antipriming pipe is connected with bottom adapter flange, the top of antipriming pipe is connected with the threeway on top.
Described tank body top is provided with safety valve 2, and described threeway 3 top is provided with capsule air bleeding valve 4.
Tank body top is provided with tank body air bleeding valve 5.
Fluid pipeline 15 near threeway 3 is provided with check-valves 11.
Described antipriming pipe adopts stainless steel 304 to make, and overall acid-fast alkali-proof, in foam solution, physics and chemical change can not occur, and has uniform hole on its surface, ensures the smooth and easy of foam solution fluid.
By adding an antipriming pipe taking stainless steel as raw material and make in the middle of the tank body of pressure type proportion mixing device, antipriming pipe is arranged in tank body, crosses whole tank body, the bottom of antipriming pipe and adapter flange place, bottom, the top of antipriming pipe and threeway position, top; Antipriming pipe adopts stainless steel 304 to make, and overall acid-fast alkali-proof, in foam solution, physics and chemical change can not occur, and has uniform hole on its surface, ensures the smooth and easy of foam solution fluid.Due to the design feature of proportioner 7, certain pressure reduction can be formed, water inlet end and water side is caused to there is certain pressure reduction, so some water enters tank body 1 with the interlayer of capsule 9 by water inlet control valve 8, inlet pipeline 14, the capsule of extruding tank interior, thus make foam solution by antipriming pipe 10, threeway 3, check-valves 11, fluid pipeline 15, go out hydraulic control valve 6 and be finally pooled in proportioner 7.Concrete principle is after the inside interlayer entered between tank body and capsule when ducted water, due to the pressure effect of water, water is from periphery to the capsule of centre extruding tank interior, the foam solution of capsule is by being built up in middle antipriming pipe, arrive the threeway at top thus eject, the extruding of capsule in extrusion process before avoiding, laminating and there is the large problem of residual quantity that gap causes, foam solution had living space, has passage, sequentially enter in pipeline, the utilization rate of foam solution increases greatly.The present invention is by joining antipriming pipe 10 after in tank body, be equivalent to add a transport channel in tank interior, when in the end stage, when foam solution concentrates on tank body lower part, due to antipriming pipe existence, play support and prevent be out of shape laminating effect, the internal clearance of capsule is compressed to as far as possible little scope, and make foam solution still continue under pressure upwards to carry, can not be affected because of the distortion of capsule, thus as far as possible many foam solutions are squeezed out, foam solution utilization rate increases greatly, and mixing ratio is also relatively accurate.
And owing to there is no antipriming pipe 10 in tank body of the prior art, when water enters into the interlayer of tank body 1 and capsule 9 from inlet pipeline, current are full of interlayer fast, increasing with rate of water added, the density ratio water of foam solution is large, make capsule formed in extrusion process above flat below the shape of rousing, cause foam solution in last course of injection, can not eject completely, there is residual foam solution all the time, cause final stage mixing ratio inaccurate.
By reference to the accompanying drawings the detailed description of the invention of invention is described although above-mentioned; but not limiting the scope of the invention; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
