Plant for casting resin processing

The invention relates to a system for processing cast resin from at least two components with at least one evacuable Premixer, a ready-mixed mixer and metering pumps for metered Feeding the components to the final mixer.

Casting resins are used for many purposes. I am a preferred area of application is electrical engineering, in which casting resins are used primarily for the impregnation of coils and other electrical components be used where there is good electrical insulation and good protection against external influences, such as moisture, arrives.

When processing casting resins, at least two components are first prepared, each of which is not fast undergo chemical or physical changes. These components are mixed together shortly before casting The * mixture reacts within a relatively short time so,

009834/1585

that the casting compound solidifies. The time it takes for a mixture to be poured while maintaining its pourability in a container can remain is referred to as "pot life".

A system for the preparation and casting of multi-component casting resins must fulfill the following tasks.

The cast resin components must be precisely dosed be mixed quickly and thoroughly, and it must be possible to use tough casting compounds with a lot of filler. The components must be able to be degassed under vacuum. A renewed uptake of gas after the degassing process must be avoided. The casting compound must be in the actual casting device be measured exactly according to the workpiece size. In order not to render the system unusable, all components must hardening residues such as hardening casting compound or filler deposits be avoided. In order to also include casting compounds that wear out the system heavily (especially casting compounds with abrasive fillers) To be able to use, easily replaceable and simple wear parts must be provided. Also need flushing circuits be provided that prevent components or ready-mixed casting resin from sticking. The plant must be heatable and coolable to certain temperature conditions to be able to adhere to.

In known systems for casting resin processing, premixers with agitators are used, which can be driven by means of electric motors

009834 / 168S

are. The removal of the components from the premixers required by dosing either a vent or the Vormischerbehälter such a high arrangement of the premixer that the ^v Eomponentensäule -not more may be retained by vacuum. When ventilating, there is a risk that the components will absorb gas again, while the high-lying arrangement of the container increases the system costs considerably and is often not possible for structural reasons.

With known systems, work is usually carried out in batches, i.e. a certain amount of components is initially added in the ready-to-use mixer mixed. This amount must be poured within the permissible pot life. When breaks in casting operations are avoided should, every ready mixer must have a further ready mixer connected in parallel so that a further batch can be prepared while a batch is being used.

The invention is based on the object of a system of the initially to train mentioned genus so that the premixer also can be kept under vacuum during their emptying and continuous operation is possible.

This object is achieved according to the invention in that a piston pump is arranged at the outlet of each premixer whose cylinder protrudes into the substance contained in the premixer and whose piston in the suction-side dead center creates a flow connection with a large cross-section between the

009834/1585

the holding substance and the inside of the pump cylinder.

In such a system, the components can also be used without ventilation or high-level arrangement of the premixer container can be fed to the metering pumps. This is possible because that no significant pressure gradient is necessary to feed the substance to be removed from the premixers to the piston pump. Because the pump cylinder can be turned into the material to be conveyed protrudes into it, the cylinder will definitely be filled. During the pressure stroke of the pump piston, the substance can be subjected to any overpressure the metering pumps are fed so that these metering pumps can also be arranged above the premixer. This is of great advantage for the construction of the entire system. In a preferred embodiment of the plant according to the invention is im Container of the premixer a reciprocating drivable rod in a vertical or at least obliquely downwardly inclined Position arranged that a at least during part of the Rod stroke immersed in the material in the form of one or more bodies protruding from the rod, such as discs and at their lower end carries the pump piston. At a such premixers are only required to operate to and fro. Stirring in rising gas bubbles as occurs with rotating agitators, this does not happen when the premixer according to the invention is operated.

Further design features of the premixer emerge from the subclaims and the following description of an embodiment of the invention.

The discharge sides of the premixers 50, 51 are connected to the metering pumps 53 and 54 by pipes 66 and 67. To the Lines 68, 69 are connected to the pressure sides of the metering pumps 53, 54, which branch, with one branch 70 or 71 via valves 62 or 65 into the container of the premixer 50, 51 returns, while the other branches 72 and 73 open into the mixer 55 via the Y-valves 63 and 64, respectively. From the delivery side A line 74 of the ready-mix mixer 55 leads to the pin metering head 56.

The following are based on the Pig. 2 to 4 the nature of the Premixer 50, 51 and, with reference to FIG. 5, the nature of the Ready mixer 55 described in more detail.

The main parts of each premixer 50, 51 (only a single premixer, namely the premixer 50 is shown in FIGS. 2 to 4), are a container 1, a rod 2, which can be driven back and forth by a double-acting pressure cylinder 3 is a pump piston attached to the lower end of the rod 2 4, which can be moved in a pump cylinder 5, and a mixing element 6 in the form of a disk. The nature of these and other components and their interaction are described in more detail below.

The container 1 has a cylindrical upper part 7, to which a frustoconical part 8 connects at the bottom, which in turn again in a cylindrical part 9 of a much smaller diameter than the diameter of the cylindrical part 7 over-

009834/1585

goes. The container 1 is vacuum-tight at the top by a cover 10 closed. In the lid 10 there is a filling opening which is closed off by a smaller lid 10 ». In the vicinity At the upper end of the container there is a suction nozzle 11 for connection to the vacuum pump 52. It is also the same Opposite height, a connection piece 12 for the return of the e.g. conveyed to the metering pump and there excess Material provided. The container is via consoles 41, 42 supported.

The upper end of the rod 2 is connected to a piston 13, which is displaceable in the cylinder part 14 of the double-acting pressure cylinder 3 and seals against the inner wall of the cylinder. By alternately supplying pressure medium, e.g. compressed air via the lines 15 and 16, the piston 13 and so that the rod 2 can also be moved back and forth c

The piston 4 consists of a bell-shaped upper part 17 and a screen plate 18 attached to the end face in the bores 19 are provided. From the closed by the sieve plate 18 In space 20, a bore 21 emerges. Four lines 22a to 22cL In open into bore 21 (see FIG. 4) a valve 23 is provided for each of these lines. The lines end with penalties 24 * which, like the top view neeli Fig. 4 sloping, pointing in a tangential direction. They are also something directed downwards, which is the case with the spray jet shown in FIG. 3? ig * 2 is recognizable. Bar outside knife of the Kolbomi 4 eats smaller

than the inner diameter of the cylinder 5, so that a gap 35 is present between the piston skirt and the inner wall of the cylinder is.

The lower end of the space in the pump cylinder 5 is closed off by a sieve plate 25 in which bores 26 are provided are, In the upper area of the cylinder 5, a total of four inflow openings 27 are attached, which the interior of the pump cylinder Connect 5 to the interior of the container 1.

The container 1 is closed at the bottom by a cover 28 on which a connection piece 29 is located. At the connecting piece 29 a valve 30 is attached, from which the line 66 (see Pig. 1) leads to the metering pump 53.

The mixing element 6 is designed as a disc, the diameter of which is smaller than the inner diameter of the container 7, so that A gap 34 of considerable width is created between the outer edge of the disc and the inner wall of the container. There can also be several disks arranged one above the other are used. The discs can be perforated. Instead of discs, other shaped ones can also be used Organs, e.g. wings or blades are used.

The pre-mixer works as follows.

When starting up, the substance 36 to be processed is first shown in filled the container 1, until the loading

holder is about half full, namely up to the fabric mirror 37. If the substance is also to be degassed, the container is connected to a vacuum pump via the suction nozzle 11. The suction of the gases is indicated by the dotted lines 38.

Sun, the rod 2 is moved back and forth by alternately pressurizing the piston 13 with compressed air or pressurized oil » With this type of drive, the components are overloaded avoided, since the intended pressure limits the driving forces accordingly. In Pig. 2, the rod 2 is on the way down, which is indicated by the arrow 39. The disc 6 is pressed into the fabric 36, whereby this the The flow around the pane edge, which is indicated by the arrows 40. The substance located below the piston 4 is now in the event that the valve 30 is closed, through the sieve bores 19 squeezed through and rises in line 21 to the top. From the line 21 of the pressed substance reaches the Lines 22a to 22d and the pressure relief valves 23 to the nozzles 24. When passing through the pressure relief valves, the mass is homogenized. The substance is sprayed out of the nozzles. Due to the recoil effect, a torque is exerted on the rod 2, so that calibrate this in rotation. In this way, fillers adhering to the wall of the mixing vessel are rinsed off. Part of the below of the piston 4 located substance is also squeezed through the gap 35 between the piston and pump cylinder 5 and in this way returns to the supply above the piston.

The top dead center is in Pig. 3 shown. There is also to rope so that the disc 6 is immersed from the material 36. In the upper lotpmikt the piston 4 assumes a position that is above the inlet bores 27 is located. So by the effect of gravity, which, when the system is not working under vacuum, is amplified by an overpressure above the level 37 can be, substance 36 flow into the cylinder. When it emerges from the material 36, the disk 6 has some of the material taken upwards, which greatly increases the surface area, which is advantageous for degassing. Through the dotted Lines indicate how gas is withdrawn from the fabric.

The ready-mix mixer shown in FIG. 5 has a base body 75 on which an essentially cylindrical part 76 is attached. A rod 77 is mounted in the base body 75. The rod is firmly connected to a piston 78 which carries a piston ring 79 which is inserted into an annular groove 80 of the piston 78. The piston can be displaced in a cylinder 81. S ⁱ at one end of Zylindex opens into this a line 82 and at the other end which is closed by a cover 83, a line 84th

The rod is surrounded by a chamber 85 arranged in the base body, which is connected to a rinsing circuit via lines 86 and 87. The rod is sealed towards the cylinder 81 by a seal 03 and towards the mixing chamber located within the cylinder 76 by a seal 90.

At the end of the rod 77 protruding from the base body 75, the mixing element designated as a whole by 91 is attached. This mixing element consists of four disks 92 to 95. The disks 92 and 95 have approximately the same diameter as the mixing chamber 89, so that only narrow gaps 96, 97 are present between these disks and the mixing chamber. In the Disks 92, 95 are holes 98. The disks 93, 94 located between the disks 92, 95 are not over theirs entire circumference adapted to the wall of the mixing chamber89, but at 99 and 100 have a greater distance from the mixing chamber wall.

A line 101 branches off from the mixing chamber. The inflow to the mixing chamber takes place via the two lines 102 and 103. The Line 102 opens into an annular channel 104 which extends outward through the cylinder 76 and inward through a cross-section U-shaped part 1Q5 is complete. There are holes in this part 106 are provided, which connect the annular channel 104 to the mixing chamber 89. The line 103 opens into an annular channel 107, the nacli outwards through the cylindrical! part 7 & and after is limited on the inside by an accumulator piston 108.

The storage piston 108 is surrounded by three seals 109, 110 and 111. Between the seals 109 and 110 there is an annular channel 112 in the cylindrical body 76, which is connected to the flushing agent circuit via lines 113p 114. Between at DiehtuiiffGii 110 and 111 there is another aiial 115 _? a stylus 116 engages in ilen.

The stylus 116 contacts the storage piston 108 from the outside. Located the storage piston 108 is in such a position that the annular groove 117 is at the same height as the stylus 116, this is pressed inward by a contact spring 118 resting on it from the outside, whereby the contact piece 119 comes into contact with the mating contact piece 120.

The upper end of the storage flask 108 protrudes into a space 121, which is closed at the top by a cover 122. In A line 123 opens into space 121. At the upper end of the storage piston 108 is located in a narrow flange 124 »of the Stop to limit the downward movement of the accumulator piston 108 serves.

The system according to the invention works as follows.

The components are prepared in the premixers 50 and 51, i.e., degassed with the aid of vacuum generated by vacuum pump 52 and with filler, dye or other modifying agent mixed. The Vormisohar 50, 51 work during this phase in conjunction with the Vcüniumpuaipe 52 alone.

The pneumatically "or hydraulically operated valves 62, 63, 64, 65, only the path via the callback line 7ü or 71 is open for the components during the processing phase, on the other hand locked after the finished mill 55.

When the preparation is finished, the casting process is initiated electrically. The working cycle of the premixer now runs as a function of the metering pumps 53, 54 and the final mixer 55, cLh. the control valves 59, 60 are operated synchronously. While the pistons of the metering pumps 53, 54 move into the receiving position, the premixers 50, 51 press the components toward the metering pumps with the aid of their TOv (Iq r pistons 4, whereby a fast and complete filling of the metering pumps is achieved. The valves 63, 64 are closed and the valves 62, 65 are opened to allow the excess material conveyed by the Pöräerkolben 4 of the Vorini shear 50 to the metering pumps 53, 54 to flow back into the premixer 50, 51.

Corresponding to the movement of the dosing pumps 53, 54 also leads the pusher 55 performs a mixing movement. However, it is also possible. to assign several mixing movements to a metering pump stroke, but in most cases this is not necessary,

the piston rods 2 of the premixer in the upper end position and the mixing element 91 in the ready-mixed mixer goes into its starting position.

So that the components can get into the mixer 55, the pneumatically or hydraulically "actuated" components first Valves reversed, i.e. the valves 62, 65 are closed and the valves 63 and 64 are opened. The one in the mixer 55 pressurized mass is then poured by the fine dosing head 56 in the vacuum container 57 or under atmosphere in shots. Since a controllable pressure of several Atü is available for filling the fine metering head 56, metering can take place in quick succession will.

After the metering pumps 53, 54 have carried out their delivery stroke, the pistons of these pumps run in the receiving position and the premixers bO, 51 refill components. These components flow to the ready mixer via lines 102 and 103. When entering the mixer (FIG. 5), the component entering via the line 103 flows through the narrow gap between the outer surface of the storage piston 108 and the inner surface of the part 105 and is thus evenly distributed. The component fed via the line 102 is pressed through the bores 106 and thereby dissolved into rays which mix with the component distributed to form a film. This type of feed already ensures that the components are thoroughly mixed. The mixing element 91, which moves up and down in the mixing chamber 89, is used when the

Components already created mixture during the upward movement of the mixing element pushed through the bores 98 of the upper disk, through the disks 93 and 94 on one forced winding path and finally pushed out through the bores 98 in the lower disk 95. This will an intensive mixing achieved.

Once the process has been initiated, it is automatically dependent away from the consumption of mass at the metering head.

The system can also be used in such a way that the process takes place entirely or partially under atmospheric pressure. So if a Vacuum degassing is not required, the use of the vacuum pump 52 can be dispensed with. On the other hand, the components are prepared in the premixer under vacuum, then completely mixed in the absence of air and under atmospheric pressure to be shed.

The mass throughput through the ready-mixed mixer 55 is controlled by a pumping time relay (not shown) and made dependent on the number of metering pump strokes per unit of time. The danger of sticking of the ready-to-use mixer 55 and fine dosing head 57 is indicated visually or acoustically in good time and can be eliminated by increasing the semolina speed (flushing with fresh mass) or by rinsing the ready-mixed mixer 55 and the other parts that come into contact with the mixed mass with solvent from the container 58 will.

If a continuous pouring stream is to be generated, the fine metering head 56 is controlled by a simple pouring valve with a reducing nozzle replaced. The maximum throughput through the pouring nozzle is so great that when the mixer 55 makes contact, the metering pumps 53, 54 are each ready for funding. The storage volume of the mixer 55 is therefore never completely used up.

In the case of castings above a certain minimum weight, the metering of the casting compound into the casting mold can be done by the component metering pumps 53, 54 are adopted. Bs is the sum of the weights of all individual components equal to the weight of the mass escaping from the pouring valve. This arrangement has the advantage that a minimum of components are exposed to activated mass 1st.

The system also has a heating device, not shown, with which all parts that come into contact with the mass can be heated.

The control of the system is described below using the Pig. 6 considered . Although the control works automatically, it is extremely simple, as the movements of the pneumatically or hydraulically operated components take place during the Bynohron casting operation .
