Method and apparatus of lining pipes with environmentally compatible impervious membrane
View Patent ↗A method and apparatus for remotely installing a monolithic liner in a conduit is disclosed. The apparatus includes a main component body including electromagnetic actuators, pneumatic cylinders, linear actuators relays, solenoids, ion generator, attachment points for tethers, umbilical, cameras and diameter specific guides and a reciprocation head attached thereto. The longitudinally traversing reciprocation head incorporates a fluid driven rotary turbine motor assembly communicating with shaft and self cleaning dissipation device integrating both conical and inverted cone surfaces. Also included on the reciprocating assembly is an impingement block for the efficient mixing of products and a termination mechanism for the precise remote control of product flow. Additionally, the assembly provides the ion generator to direct a stream of negatively charged air flow to the shaft and the diffusion device to effectively prohibit excess material accumulation.

b) a housing including at least one heater for heating lining components;
c) a reciprocating head moveably attached to the housing and including a rotating shaft holding a rotating dissipation device shaped as two asymmetrical reversely aligned cones with a center top attached to the rotating shaft and with an acute angled flange oriented to the reciprocating head wherein the rotating dissipation device forms an acute angle to a lining stream proximate to the center top;
d) an impingement block attached to the reciprocating head wherein the impingement block mixes the lining components and projects the lining at a specific angle of trajectory to the rotating dissipation device; and
e) a remotely activated termination rod extending through the impingement block wherein heated and pressurized lining components enter the block and are mixed and projected out of a stream tip orifice to the dissipation device by retraction of the termination rod.
2. The apparatus of claim 1 further comprising a first lining component of heated isocyanate and a second lining component of a heated amine resin.
3. The apparatus of claim 1 further comprising applying a lining containing no volatile organic compounds or chlorofluorocarbons.
4. The apparatus of claim 3 wherein the apparatus heats and highly pressurizes the liner components and causes the mixed liner to cure in approximately 5 seconds.
5. The apparatus of claim 1 wherein the liner is impervious to effluent and prevents the migration of effluent from the pipe into the environment.
6. The apparatus of claim 1 further comprising a stream of negatively charged ions directed to the rotating dissipation device.
7. The apparatus of claim 1 further comprising the rotating dissipation device rotating in a range of between 20,000 and 45,000 rpm.
8. The apparatus of claim 7 further comprising lining material that moves back toward the center top is removed by the force of the lining stream projected from the impingement block.
9. The apparatus of claim 1 further comprising a motor driven propulsion device to move the apparatus forward and reverse in a pipe.
10. The apparatus of claim 1 further comprising articulated housing sections permitting the apparatus to maneuver through bends.
11. The apparatus of claim 1 further comprising a pocket segment and the acutely angled flange oriented to the reciprocating head and wherein the lining stream impacts the dissipation device and moves forward and up an interior acute angled flange of the spinning surface to the pocket segment and up the acute angled flange wherein the lining stream is projected off of the flange edge and onto the pipe wall.
12. The apparatus of claim 1 further comprising the rotating dissipation device moving forward and reverse in relation to the apparatus.
