Two spray heads (H1, H2) are present for use in lining a pipe (P1), the heads being arranged in line and arranged to apply composition in succession to the inner surface of the pipe.
Description
The present invention relates to the apparatus and method of lining of pipes, especially for the lining that is coated with of the pipe of carrying potable water, sewage, rock gas or similar thing.Lining is mainly synthetic resin, such as epoxy resin.
DT-A-2,448,932, GB-A-2,218,773A and GB-A-2,065,263A has disclosed the lining of pipes device, wherein, has formed a ring bodies that is coated with lining liquid on the barrel surface that is coated with the lining device, and by the internal limitations of pipe.Therefore, push away before this device, during hole by pipe, the liquid that contacts with inside deposits in the above.
It is well-known by the pipe that will be coated with lining that pulling is coated with the lining device, and this device has a shower nozzle and mixing arrangement, is used for the lining mixture that is coated with that will spray is coated in the surface that will be coated with lining.Be coated with the lining mixture, be generally hybrid resin and hardening agent, be inhaled into shower nozzle, shower nozzle is with such speed rotation, and promptly its rotational speed can make the particle atomizing and be coated onto the surface that will be coated with lining.In this device, normally used shower nozzle be shaped as cylindrical barrel, cylinder is around its rotational, and discharges by the eyelet on its cylindrical wall and to be coated with the lining composition.This device is used on the minor diameter pipe better, and is still, big and/or when requiring to be coated with lining and not having ditch when diameter, not too effective.
GB-A-865,301 and DE-A-4,400, the 166 lining of pipes devices that disclose comprise that is suitable for a carrier that moves in being coated with the pipe of lining, one is used for carrying the delivery pipe that is coated with the lining composition that will spray to the shower nozzle that is positioned on the carrier, and the device of the axis rotation that is used to make shower nozzle center on pipe.
The invention provides a kind of lining of pipes device of type as mentioned above, it is characterized in that, shower nozzle has an annular surface, and its axis is consistent with the spin axis of shower nozzle, and this surface has the outer periphery part, is used for ejection and is coated with lining material.
Delivery pipe preferably is mounted to can be axially, carry skim to be coated with lining material from the surface to the edge section.
This device preferably includes two or more at axially spaced this shower nozzle, and when carrier moves in the pipe that will be coated with lining, be used to spray separately be coated with the lining material coating.
Other premium properties illustrates in appended claims.
The present invention also provides a kind of method, and wherein, shower nozzle has an annular surface, and its axis is consistent with the spin axis of shower nozzle, and this surface has the outer periphery part, is used for ejection and is coated with lining material.
The present invention also provides a kind of shower nozzle that is used for the lining of pipes device, the characteristics of shower nozzle are, a upright cylindrical side wall is arranged on the disc bottom surface usually, and when around its rotational, its shape can make the lining composition that is coated with of atomizing spray from wall upper edge radially outward.
Spray-coating apparatus should comprise two shower nozzles at least, and each shower nozzle comprises a disc bottom surface with upstanding sidewall usually, and its shape can make the lining composition that is coated with of atomizing outwards spray from wall.The top of sidewall preferably is outside funnel shape.In addition, perhaps as a kind of selection, porose on sidewall.
The diameter dimension of shower nozzle for example, at 50mm to the scope of 350mm.
For the present invention is understood easily, below will be only the example shown in conjunction with the accompanying drawings present invention is described, wherein:
Fig. 1 is total figure of an embodiment of device of the present invention;
Fig. 2 A be used for Fig. 1 device, have an end view of the device of two shower nozzles;
Fig. 2 B is the part longitudinal sectional drawing along the line IIB-IIB among Fig. 2 A;
Fig. 3 is the longitudinal sectional drawing that is used for other nozzle device of apparatus and method of the present invention to Fig. 5; And
Fig. 6 is the floor map of the device of Fig. 1.
When describing different embodiments, may use identical reference number, add suffix behind the reference number.
Lining coating machine device shown in Figure 1 comprises air compressor commonly used and rotor machine 1, pump-unit 2 and storage 3,4, and storage is used to store unhardened resin and hardening agent.The soft delivery pipe 3A, the 4A that come out from storage are wrapped on the winch spool 5, and extend to forward on the carrier 6 of the pipe P that its size can be by will being coated with lining.Carrier 6 comprises dolly 7, and dolly has wheel or slide rail, and dolly passes pipe P by wheel or slide rail, and carries an online static mixer 8, the feeding in mixer of soft delivery pipe.Motor 9 is used for rotary nozzle device H, and as shown in Figure 1, nozzle device is made up of several shower nozzle H1, H2.Shower nozzle is made by aluminium or materials similar.
As shown in Figure 2, each shower nozzle is disk 10, and it has a upright sidewall edge 11.Extending axially from mixer 8 extended delivery pipes 12 along shower nozzle, and there is side opening 13 in the place bottom contiguous shower nozzle.The inside on the top 14 at edge 11 is outward-dipping, and as shown in the figure, and shoulder 15 is used for 16, one shower nozzles of connecting bolt and is fixed on another shower nozzle (shown in Fig. 2 B, only on shower nozzle H1 shoulder being arranged) by bolt.When rotating, shower nozzle (such as reaches 10,000 rev/min), the hybrid resin composition of 13 ejections arrives edge 11 along the bottom (shown in path 20) of each shower nozzle from the hole, be atomized at this, and from the edge 11 external cylindrical edge section, with the dish out surface of the pipe P that will be coated with lining of spray 21.Because every row has two shower nozzles, therefore, lays the two-layer lining that is coated with successively, complete to guarantee being coated with lining, when the material of pipe conveying is potable water, do being even more important like this.
In the embodiment of Fig. 2, two shower nozzle H1 and H2 have discoid bottom.As shown in Figure 3, the bottom 10A of shower nozzle H1 can be curvecd surface type, with passing through of the composition that will lay of influence.As shown in Figure 4, three shower nozzle H1, H2, H3 can be installed, shoulder 15 is arranged on shower nozzle H1 and H2.As shown in Figure 5, edge 11A can be porose 17, so that the particle of atomizing can emerge from the side of shower nozzle, replaces or concur with emerging along the part 14 at edge.
Use well-known method, the size of shower nozzle and/or the speed of rotation and the density that is coated with the lining composition can be adjusted each other, lay the speed of coating with control.
Want the pipe of coating to be assembled together, reaching the length of connecting duct, and pipe can be made with cement, plastics, metal or materials similar.
With reference to figure 6, the carrier 6 among the figure is connected with Trailer equipment 18 with hardening agent supply hose 3A, 4A and air hose 19 by resin; Generator/blowing plant 1, resin and hardening agent jar 3 and 4, hose reel 5 and relevant main pump 2 are installed on the trailer, and other device.Air duct 19 provides pressurized air, drive the pneumatic motor 9 on the carrier, and it is connected with air supply pipe 20.
As shown in the figure, resin, hardening agent and air supply flexible pipe are connected on the spool 5, and when carrier by belt winch 24 (being connected) when being pulled through pipe with a pipe that does not illustrate, is connected on the carrier, under the control of gear-box and motor 21, clutch 22 and another gear-box 23, can be fed on the carrier 6.This device is by 27 controls of a control panel.
Temperature (thereby density of resin and hardening agent) can be by fan-type heater 25 and fan cooler 26 controls.
The present invention is not limited to illustrated embodiment.The present invention also can have the shower nozzle more than three: each departs from another (or several in addition); Resin is epoxy resin not necessarily.
