Preferably, the first reinforcement is identical with the diameter of section of rectilinear tubes with the other end of bend pipe distance size.
By using technique scheme, then the liquid of unsaturated polyester resin by entering fill district by rectilinear tubes after bend pipe, the flow velocity of liquid to be kept is the same, so that the size of the cross-sectional distance of bend pipe is identical with rectilinear tubes diameter of section, the deformation that not only bend pipe simultaneously also can be made to produce is minimum, and it is consistent to reach flow velocity, meets technological requirement.
Preferably, the thickness of the first reinforcement is gradually reduced toward both sides from center.
By using technique scheme, owing to the angle of bend of bend pipe is different, at bosom, the angle of bending is maximum, and farthest with the distance of the bend pipe other end, two ends are then contrary, so center thickness is maximum, and the thickness toward two ends is gradually reduced, and meets structural requirement.
Preferably, the first reinforcement two ends are provided with the first ceramic layer for preventing wall built-up.
By using technique scheme, when fill terminates, the top of the first reinforcement can remain the residual in order to prevent liquid, so arranging one layer of first ceramic layer so that liquid runs down ceramic layer flows down.
Preferably, the second ceramic layer of acid and alkali-resistance it is provided with in body.
By using technique scheme, owing to liquid is that reaction is successful under acid-base condition, liquid may prevent the corrosion to transport pipeline with the material of soda acid, extends the service life of pipeline.
Preferably, bend pipe is connected with the outlet of tee T, and another outlet bridge piece of tee T, the import of tee T connects cone pipe.
By using technique scheme, after reacting due to unsaturated polyester resin, can obtain the product of different levels, by the height of concentration at equipment Inspection, a point tee T to be passed through shunts, and reaches to meet the requirement of the concentration of different needs.
Preferably, being provided with concentration detector in cone pipe, concentration detector is positioned at cone pipe internal surface.
By using technique scheme, the detection of the concentration of unsaturated polyester resin is detected by the concentration detector being arranged in vertebral body pipe, owing to vertebral body pipe is narrow, the speed that liquid passes through is than very fast, can result at detection in time, then by, after tee T, entering the pipeline transported for this concentration.
Preferably, bend pipe is connected with the electric control valve being realized keying by concentration detector signal feedback.
By using technique scheme, after concentration detector detects concentration, signal feeds back to PC end, and then PC end controls electric control valve and realize the keying of valve so that liquid can enter the transport pipeline needing to enter, it is to avoid causes fill mistake, causes enterprises' loss.
In sum, this utility model has the advantages that by increasing the first reinforcement and the second reinforcement, and adding bend pipe and the intensity of cone pipe, unsaturated polyester resin transports under vacuum, and the deformation that bend pipe and cone pipe are subject to reduces.
