Description

The present invention relates to a process for air-tightly homogenizing and / or pumping liquid, settling edges and / or dense materials in the same workflow. The invention also relates to an apparatus for carrying out the process.

As it is known, the application and liquid application of liquid settling materials is expanding at an accelerated rate, primarily in the field of plastics, paints and varnishes. This development was made possible, in part, by the appearance of new materials and techniques, and partly by the demands of environmental protection. The use of various aqueous emulsions, but not least Wine, was influenced by considerations of economy, e.g. fluid plastic compositions in the field of plastic tillage have enabled highly automated work processes. Especially progress has been made in this direction eg. earth working of reactive plastics based on two-component silicone and urethane with settling filler. Part of this development was the modernization of appropriate machinery. In fact, such processes generally involve pumping, mixing, and dispensing devices mounted directly on the container of liquid plastic. [Elastomerics (1980) Feb. 18; Gummi, Asbest, Kunststoffe 36, No. 9, 458-466 (1983). Since continuity is one of the decisive elements of such processes, state-of-the-art processes and equipment, apart from the need for periodic tank replacement, e.g. the components of the pumpable, liquid, multi-component reactive plastics are mixed together in a static mixer. Static mixers are known per se: M. Szab. 179.046 ^ D.P. 1,178,404; DT 23 52 480; U. S. P. 2,847,649, 3,195,865, 3,286,992, 3,871,624, 3,918,688.

As you can see, the most advanced processes so far have ensured continuity from the transport container: transport, mixing and dosing in controlled operations. But since the materials involved in such manufacturing processes are, by virtue of their fluidity, predominantly sedimentary, e.g. they also contain settling fillers or aqueous dispersions that are stable for a limited time, so homogenisation of the material should be done in the transport tank, at least prior to commencement of soil cultivation, but in many cases at the beginning of shifts, or more frequently depending on sedimentation. But the otherwise indispensable pre-homogenization, if done without any special action, as usual so far, usually introduces air into the material, which appears in the form of inclusions, bubbles, harder than dense materials, and can only be removed at the expense of another expensive vacuum workflow. , because otherwise it is incorporated into the finished product, which sometimes diminishes its quality. For example, power insulation technology, where, especially at higher operating voltages, the air tightness of the insulation can render the entire product unusable. However, this homogeneous pre-homogenization of the material, which is still generally unavoidable, in addition to the above disadvantages, even though disadvantageous, inevitably impairs the continuity of tillage, since it can only be performed in stages. All this is supported by the fact that the usual conveying container is cylindrical, smooth inside and after removal of the outer sealing cap of the container, e.g. on top of dense material, the so-called piston a pressure plate, which is e.g. is mounted on a piston-type pump such that it is passed through an opening in the center of the pressure plate n, i.e. the pump is regarded as the stem of the pressure plate. This "plunger" of pressure plate and pump is moved downward by force and downstream of the material chosen for the viscosity of the material, which ultimately reaches the bottom of the tank at the rate of material loss. This arrangement is used because in this way virtually all material can be removed from the container without loss. This requirement, which is so important in practice, could not be met if, for example, the material contained in the container was a separate agitator blade would be immersed, as this would prevent the pressure plate from moving throughout the container following the level of the material. However, the pressure plate and the pressure applied to it are necessary for the good pumping of often very dense materials. Therefore, homogenization of the contents of the transport container has been carried out in advance with a separate cover, assuming either the possibility of airtightness or vacuum evacuation, e.g. interposition. Vacuum treatment of dense materials is not always possible in practice acceptable to u.

It can be seen from the above that even the most advanced solutions used so far, the conveying and dispensing equipment capable of conveying dense, filled, liquid plastics, have not been solved easily, e.g. without vacuum, the task of homogenizing or maintaining the material in a continuous or airtight manner, keeping it homogeneous.

Λ It is an object of the present invention to provide a solution for homogenizing and / or pumping a fluid, settling and / or dense material in a single workflow in an airtight manner.

The invention thus provides a method for airtight homogenization and / or pumped delivery of liquid, settling and / or dense materials, wherein the material is transported from a tank by means of a pump, a closed pipeline, according to the invention initially to a full pumped amount at least in part, to the place of use.

The advantage of this solution is that it allows homogenisation of the aeration of liquid, settling sludge and / or dense materials without pump rotation and venting operation in the pumping transport. tools and in the same workflow.

Preferably, the material is pumped from the bottom of the container and waxed directly below the liquid material foam. This is advantageous because with fast settling materials this forces the longest settling process.

However, it may also be desirable to pump the material from below the bulk of the liquid material and return it to the bottom of the container. This is advantageous because in the case of aqueous dispersions, the film-resistant organic phase can thus be forced to a better distribution.

Further, after homogenization, some of the pumped material is still recycled. This is advantageous because even with rapidly settling materials, homogenisation can be ensured.

It is also desirable to further homogenize the material during the recycling in a static mixer. This is advantageous because it allows for a finer homogenisation within the pumped amount of material delivered in increments.

Preferably, the material is shaken at least during homogenization. This is advantageous because many materials liquefy under vibration, which facilitates pumping and improves homogenization.

It is also desirable to keep the material in the container under pressure at least during pumping. This is advantageous because it allows reliable pumping for denser materials.

The apparatus according to the present invention comprises the connection of a manifold inlet to the discharge port of the pump, a pipe returning to one outlet of the distributor valve and a pipe leading to the place of use of the other outlet, the inlet port of the return pipe being inserted into the material.

Preferably, the suction nozzle is below the level of the inlet nozzle. This is advantageous because in the case of sedimented slurry, the contents of the container can be effectively homogenized.

However, it may also be desirable to have the inlet manifold below the level of the inlet manifold. This is advantageous because in the case of aqueous dispersions it allows an effective homogenizing distribution of the non-aqueous phase.

It is also desirable to have a static mixer inserted in the return pipe. This is advantageous because the flow of recirculation is thus passed through a static mixing belt providing a very high degree of uniform mixing.

It is also desirable that the apparatus has a pressure plate for sliding sealing of the material in the reservoir, a pressure pipe with a sliding seal and a suction and vent connection, and a sliding mechanism for applying pressure to the pressure plate and the pump, the suction port opening is in the plane of the pressure plate and the return pipe is provided with a seal that slides over the level of the material in the container. This is advantageous because the surface color of the material in the container can be sealed with the pressure plate and pressurized by the venting nipple, which is airtight, and facilitates the flow of material into the suction nozzle, while the material is pressed against the can be driven back, and at the end of the workflow, air can be introduced through the venting nozzle and the slider allows the pressure plate and pump to be easily withdrawn from the tank.

Further, the apparatus has a device for moving the container containing the material in the direction of its vertical axis, the drive device being fixed to one side of a mounting frame, the pump being joined to the opposite side of the mounting frame along with the pressure plate. This is advantageous because the material in the reservoir can be pressurized by raising the reservoir, while the position of the pump remains unchanged, which may be required for a fixed position in twin layouts when several pumps are connected by rods.

Preferably, the apparatus has a piston system and a pump with a lifting blade formed to extend the pump-piston guide below the pump-piston and a pump-mounted shaker in the vicinity of the suction nozzle. This is advantageous because a piston pump equipped with a lifting vane for transferring dense materials can also transport very dense materials liquefied by the shaker.

It is also desirable if the apparatus has a pump-driven air motor, a reservoir sliding out of the air cylinder by means of a sliding gasket to extend the drive air motor piston rod over the air piston by shaking the material around the intake manifold. This is advantageous because otherwise flexible seals allow the vibration energy to be transferred to the affected material range without having to shake the entire pump or the entire material through a mechanically isolated moving system and directly by the lifting bar. and a pneumatic vibrator utilizing the air supply to the air motor as a shaker.

As shown in Fig. 1, the sump 9 of the pump 3 flows into the material 1 in the tank 2, the inlet 7 of the manifold 7 to the outlet 6 of the pump 3, the pipe 14 to the outlet and the return pipe 8 to the other outlet 8. .Bank 10 at the end ends in material 1. The material 1 in the tank 2 is lifted out of the suction nozzle 9 of the pump 3 and then discharged through the discharge nozzle 6 into the distribution valve 7, according to which the flow is through the inlet pipe 14 and / or the return pipe 8 and its inlet 10. Returns to material 1 in 2 containers.

Fig. 2 shows the same as Fig. 1 with the exception that the suction nozzle 9 is located at the bottom of the container 2 and the inlet nozzle 10 is below the surface of the material 1. The bottom layer of material 1 in the container 2 is introduced by the pump 3 into the upper layers of material 1 via the inlet port 10 below the surface of the material 1 in the one-way position of the valve 7 as shown in FIG.

Fig. 3 shows the same as Figs. 1 and 2 with the exception that the suction nozzle 9 is below the surface of the material and the inlet nozzle 10 is at the bottom of the container. The upper layer 1 of material 1 in the tank 2 is returned by the pump n 3 to the lower layers of material 1 in the one-way position of the distribution valve 7 as shown in FIG.

Fig. 4 shows the superimposed ones in Fig. 1, except that a static mixer 5 is inserted in the return pipe 8. The material 1 in the container 2 is, as shown in Fig. 1, positioned in the distribution valve 7 and then in the pipe 14 to the place of use and / or the static mixer 5 and the return pipe 8 and then its inlet 10 in the container 1. gets back to the material.

Fig. 5 shows the material 1 in the container 2, the surface of which is closed by a pressure plate 4 fitted with a sliding seal 15 to the inner wall of the container 2. On through a pressure plate 4 into the material 1 in the container 2, a vent 29, a suction 9 of the pump 3, and a return pipe 8 with an inlet 10 through a nozzle 13 which runs to one of the outlets of the distributor valve. mig inlet is connected to the discharge port 6 of the pump 3. The pump 3 is enclosed in a sliding device 12 which rests on a common base with the tank 2.

The material 1 in the tank 2 is lifted through the suction nozzle 9 of the pump 3 and then fed through the discharge nozzle 6 to the distribution valve 7, according to which the material flow is directed to to 1 material. The distribution valve 7 allows the homogenizing recirculation on the return pipe 8 to be intermittent. The surface of the material 1 is sealed by the pressure plate 4, the space below which may initially be vented through the venting port 29 at the initial insertion of the pressure plate 4 into the container 2 sealed by the sliding seal 15, but before reaching the surface of the material 1. it also means that the appropriate parts of the pump 3 are vented and thus prevents bubble formation when starting the workflow. The insertion of the pressure plate 4 into the container 2 as described above is effected by the pusher 12, e.g. This can also be used to pressurize the material 1 in the reservoir 2, which provides for a smooth supply of material to the pump 3 via the suction port 9. The 2 containers are standard factory packaging! and n e.g. so-called liquid silicone rubbers, the usual density, e.g. For the transport of material having a viscosity of 600,000 mPas. 3 bar pressure required. The disappearance of the material 1 in the container 2 following the plate 4 in this way, the attachment 3 _v pump collectively. The wax guide tube 8 'fits into the pressure plate 4 with the sliding seal 13, and therefore, e.g. with telescopic design, it can adapt to the sinking level of the material 1 in the container 2 and to the respective position of the subsequent pressure plate 4. In this way, the homogenizing recycle on the return pipe 8 can continue until the material 1 has been completely discharged from the container 2, e.g. it would not be possible with the usual mixing paddle homogenizer arrangement. Thus, when the material 1 has completely run out of the container 2, the pressure plate 4 may lie on the lower surface of the container 2. By actuating the pusher 12 in the opposite direction and by using the venting nozzle 29 as an air inlet, the pressure plate 4, the mounted pump 3 and the connecting parts from the emptied tank 2 can be unhinderedly removed from the tank 2. transport tank, a new container 2 containing the substance 1 can be replaced in its place and the process can be restarted by pushing the pressure plate 4 through the pusher 12. Thus, as can be seen, the process and the apparatus for carrying it out allow for simple and accurate homogenization of the material 1 in the container 2, while the material 1 is pumped from the container 2 and, in view of the dense materials, pressurized to facilitate this.

In Fig. 6, the material 1 in the container 2, the pressure plate 4 sealing the surface thereof with the CB seal 15, the recirculation pipe 8 with the outlet 1 of this material, connected to its other outlet is a boat 14 leading to the point of use. Also shown is a pump 3 connected to the inlet of the distribution valve 7 through its discharge nozzle 6, which on the one hand flows through the discharge nozzle 9 into the material 1 and is secured to one side of the mounting frame 28. To the opposite side of the mounting frame 28 is mounted a moving device 27 on which a container 2 containing the material 1 is placed.

By moving the actuator 27 mounted on the underside of the mounting frame 28, the material 1 in the container 2 is pressurized, since the pressure plate 4 which seals its surface is held by the pump 3 assembled with it and held by the upper side of the mounting frame 28. and 9 spool stops in one place. The actuator 27 thus exposes the material 1 in the container 2 by pressing against the stationary pressure plate 4, preferably e.g. for dense material 1, approx. 3 bar pressure. By moving the actuator 27 downwards, the mounted container 2 can be pulled off the pressure plate 4 which fits with the sliding seal 15 thereon. The operation and function of the other parts shown in the figure is similar to those already described with reference to Figure 5, except that the venting of the pressure plate 4 when it is introduced into the container 2 can also be effected through a return pipe 8 which can be moved together with the pressure plate 4. Similarly, air recirculation pipe 8, which is required for removing the container 2 from the pressure plate 4, can also be supplied with air.

6, the pressure acting on the material 1 is achieved by raising the container 2 while the pump 3 remains in a fixed position. This is particularly advantageous if several pumped materials 1, e.g. the liquid reactive resin components must be mixed in a proportion. In this case, the drive of the pump carrying the individual components is connected to the rods, usually using a common drive machine. For this, it is necessary to fix the position of the pump 3, i.e. to move the tank 2.

Fig. 7 shows a detail of the container 2 containing the material 1, the pump 3 which enters the material 1 with its suction nozzle 9 and the return boat 8. Only the parts of the pump 3 and the return pipe 8 which are necessary for understanding are shown. likewise, several details of the layouts already described in the previous figures are not shown. The pump 3 shows, in sectional view, the pump piston 20, with the pump piston rod 19 leading upwardly from it, the pump piston extension 20 extending from the material side 1 of the pump piston and the end thereof 1 25 lifting plates. Also shown in the figure is a shaker 11 mounted on a part of the pump body 3 close to the material 1.

The details of the operation of the piston pump 3 with the blade 25 shown in the figure are not described here as they are known solutions, in particular for the suction of dense materials with a viscosity greater than 200,000 mPas. However, for the solution outlined in the present figure, the operation of the liner 25 mounted on the pump plug extension 21 is essential and is therefore briefly described. As the pump piston 20 moves downward, the flat piston 25, which is seated at the pump piston rod extension 21, is pushed into the dense ointment material, carving out a channel in its direction of movement and then returning to the dead end.

However, in the meantime, the channel 25 is carved into the oily, densely flowing material

The cross-section of the -511 is narrowing, which is determined by its narrow flow rate and velocity. The lifting blade 25, thus moving backwards, must therefore expand a channel that has been previously carved into the material, which has since narrowed, roughly peeling its inner wall. Thus, the amount of dense material that has been stripped of the dense material is squeezed further by its backward-facing lifting plate 25 into the nozzle 9, from which the material flow formed in the pump 3 will be carried forward. The process then starts again. Thus, as has been seen, the viscosity-dependent rate, or rate of flow, of material 1 in this relatively small volume region of the channel 25 is decisive for such pumping of dense materials. Therefore, in the present invention, this portion of the material to be pumped is also fluidized by a shaker device 11 mounted near the nozzle 9 of the pump 3. In fact, the mechanical vibrations produced by the shaker 11 reach the material described above in a short way, purely by means of the suction nozzle 9, which is rigidly mounted on the pump. In practice, since most liquids which are thickened with fillers are pumped, they are often thixotropic and thus, under appropriate mechanical vibrations, shake to shake and then regain their original viscosity after a time-consuming relaxation of their structure. Since the vibrator 11 is used to vibrate the material 1 through the body of the pump 3, this effect affects not only the material 1 entering the suction nozzle 9, but also the flow of material moving in the pump 3. This will make the whole pumping process easier, which will not only extend the life of the equipment, but also help you adjust the mixing ratio important for multi-component reactive plastics by keeping the pumped volume delivered more per stroke. In addition, the application of the shaker 11 also results in the high viscosity of the dense materials being transported! the limit can be extended.

Figure 8 shows a detail of the container 2 containing the substance 1, the intake manifold 9 and the return pipe 8 extending into the substance 1, and the pump 3 as a continuation of the intake manifold 9. Also shown in the figure are some essential parts of the pump 3, such as the pump piston 20, the pump piston rod extension 21 extending from the bottom thereof into the material 1, and the lower end thereof. The pump piston rod 19 attached to the upper end of the piston 20 is connected to the piston 18 in the air cylinder 23 of the air motor 17 indicated by a dashed line and then extends from its opposite center plate in a vibrating shaft 24 extending from the air cylinder 23 carries. There is a sliding seal 31 between the air piston 18 and the air cylinder 23, and a sliding seal 32 between the pump piston 20 and the pump 3.

As shown in the figure, the pump 3 has a piston system and is provided with a manifold blade 25 and is powered by an air motor 17. Its operation in the pumping of dense materials is characterized by reference to Figure 7 and is known in the art and may therefore be omitted. However, the vibration transmission portions from the shaker 26, such as the piston rod 24, the air piston 18 connected thereto, the pump piston rod 19 connected to it, the pump piston 21 connected thereto, are shown as essential. extension and 25 lifting pins attached to it. Thus, it can be seen that the vibrations generated by the copper structure 26 directly cause the vibration of the lifting plate 25 to act in direct contact with the critical portion of the material 1, as detailed in FIG. It is further emphasized that the vibration amplifying portions described above are mechanically insulated from the air motor pins 17 by the sliding seal 31, the pump 3 by the sliding seal 32. As a result, the energy of the shaker 26 can be applied sparingly and purposefully only through the lifting blade 25, thereby transmitting to a critical portion of material 1 in the vicinity of the suction port 9 and without unnecessarily mechanical vibration of other parts of the apparatus. This advantage of this solution is particularly evident when e.g. compared to the solution represented by a container 2 mounted on a shaking table. Preferably, the shaker 11 is a pneumatic, commercially available and actuated power supply to the air motor 17 driving the pump 3.

The process and apparatus of the present invention have been tested for airtight homogenization and pumping of the liquid delivery state RTV ME-622 liquid two-component silicone rubber feedstock. The two components, designated A and B, are mixed in the ratio 9A: IB. Component A has a viscosity of 20-40,000 mPas and Component B has a viscosity of 1500-2500 inPas. Therefore, π in this example only describes the dehydrogenation and pumping of the dense component A according to the present invention, since dilute component B is usually added from a pressure vessel. Component A cools down. dense, flowing sediment material, which comes in a 20 or 200 liter tank. Because our goal is to make a high-power, medium-voltage product, we cannot follow the warning given by the transport company to the container 2 that the material 1 must be mixed before use. In that case, otherwise

At manufacturer 1, air contained in a container 2, filled in a sealed system, sealed with airtight air, would be mixed with air bubbles which would, e.g. would render it unusable for known electrical insulation reasons. However, by utilizing the present invention, it is possible to avoid the vacuum treatment which is common after, or associated with, such a delicate manufacturing process, which is conventional, costly and complicated. Substantially simpler is by immersing the nozzle 9 of the pump 3 according to the invention in the container 2 containing the material 1, preferably extending into the lower layers of the material 1 in the container 2 and adjusting the depth of the return pipe 8 to a similar degree. . However, if a pressure plate 4 is used, it is preferable to insert only the return pipe 8 into the bottom of the container 2. The pump used in the present example is an Auras piston system with a lifting blade, air motor drive and a material flow of approx. 3000 gr. At the start of the pumping, initially by setting the distributor valve 7, the entire amount of pumped material is recycled to the lower layers of material 1 in the tank 2 to mix the settled filler for sufficient homogenization. For example, The contents of 20 tanks 1, thus taking into account the capacity of the pump above, approx. Homogenize in 7 minutes. The distribution valve 7 can then be adjusted either so that the entire flow of material flows into the pipe leading to the main use site or partially flows back through the return pipe 8 to the material 1 in the container 2 for continuous homogenization. For the silicone rubber component A in question, a daily homogenization of the above-described 7 minutes according to the invention is sufficient, while completely avoiding airtightness.

In another case, the Waeker VPR 3003/40-HTV, a two-component, liquid, hot-vulcanizing silicone rubber feedstock was homogenized by a large-scale, so-called. for liquid polymer injection molding products. Components A and B of this material must be mixed in a ratio of 1: 1, ie pumped from the shipping container of each component. The viscosity of the material components is 600,000 mPas, which also implies that the pump 3 must be provided with a pressure plate 4, which is approx. A pressure of 3 bar must be applied to the surface of material 1 and maintained during the work process. When the pressure plate 4 and the pump 3 are introduced into the container 2, the space between the pressure plate 4 and the material 1 is vented by means of a vent 29. Before starting the pumping, switch on eg. 7, a shaker 11 used in the arrangement of FIG. 7, which is a mechanical shaker of the well-known percussive drilling machine and is operated by electric bending at 3000 to 5000 pulses per minute. Anyag the material in question, particularly in the vicinity of n 9 cardiac stumps, becomes more fluid by shaking and becomes easier and smoother by its lifting blade 25, as described in Figure 7. By shaking the material in question in the above manner, its flow rate, the characteristic volume / time ratio, has been improved by an order of magnitude. The two components A and B are transported as described above, e.g. mixed in a static mixer in a 1: 1 ratio to give a homogenized, airtight, ready-to-use mixture.
