Definitions

  • the invention relates to a method for preparing fertilizing water for household or hobby gardeners, in which the water is impregnated with CO 2 and dissolved in the impregnated water fertilizer.
  • FR-PS 11 171 059 shows a suitable injector system. This has a straight flow section through which one of the two media to be mixed flows. In this flow channel, several short pipe sections are arranged consecutively with increasing diameter, the ends of which are overlapped to form an annular gap. The pipe section of the largest diameter with respect to the straight channel is designed so that it also forms an annular gap with the channel. The flow in the channel is thus continuously divided into several partial flows.
  • a device for supplying the second of the two media to be mixed is provided centrally on the inlet side of the tube section of smallest diameter, through which this second medium is introduced into the flow in a finely divided manner.
  • This can e.g. B. done by spraying.
  • This is a system in which a mixture promoting turbulence is generated in a straight flow channel of constant cross-section with the aid of a flow control system from several differently dimensioned pipe sections, into which the second medium is injected or sprayed on the inlet side.
  • an arrangement for. B. is provided for a washing machine, in which the water feed line of this machine is associated with a metering device for adding an additive, for. B. automatically initiate a water softener.
  • the flow rate of the water is changed by the formation of a nozzle or a gradual change in the flow cross section.
  • a line for the additive opens into a mixing chamber area.
  • several bores are provided which are open to the outside atmosphere and through which small amounts of air can be drawn in.
  • Ventilation openings provided in front of the mixing zone have the purpose of preventing a vacuum from being formed in the water supply line when the water supply to the domestic machine is switched off. Because of this vacuum, the additive, e.g. B. the softener or the water mixed with it can be sucked back from the mixing chamber area into the water supply line and get into other line sections of the water distribution system. By contrast, the air sucked in through the bores ventilates the line section in front of the mixing chamber area, thus eliminating any vacuum that might occur there.
  • the invention relates to a method and an apparatus for preparing manure water for household or hobby gardener, in which the water is impregnated with C0 2 and dissolved in the impregnated water fertilizer. It is known that the health of plants, plant growth and their resistance to pest infestation can be significantly improved if the plants are watered with a corresponding proportion of CO 2 introduced by fine impregnation and a correspondingly high proportion of H 2 CO 3 contains. Appropriate systems and devices have been developed in order to supply horticultural businesses, outdoor crops and afforestation areas or the like with water prepared in this way. (See German magazine “Der Spiegel " , No. 47/1982, pages 99-101 and No. 7/1984, pages 61-63).
  • the invention takes into account the fact that the irrigation water in the household or at Hobby gardeners are usually removed from the water pipe via a tap. As is known, the water pressure in such lines is subject to considerable fluctuations. These fluctuations are automatically taken into account according to the teaching according to the invention in order to maintain a fixed degree of fine impregnation CO 2 gas, and in the preferred embodiment also with regard to the metering in of the fertilizer, without the operator having to do more than to ensure that more is sufficient There is a supply of gas or fertilizer. To get the impregnated fertilizer water when needed, the operator only needs to turn on the tap and turn off the tap when the need is satisfied.
  • the absorption and mixing in of the C0 2 gas is determined by the instantaneous lowering of the static water pressure in narrowly limited areas of the external liquid layers when overflowing the shoulder-like cross-sectional enlargements of the flow path in the impregnation zone and by the narrow and open holes corresponding to the shoulder width, which these external liquid layers bring into direct contact with the distribution zone for the CO 2 gas.
  • the device provided for carrying out the method can be designed to be extremely compact as a device block which can be easily attached to a conventional water pipe and whose outlet can be designed directly as a tapping point.
  • a liquid fertilizer is used, the feed into the water flow of which is controlled automatically and in each case in the correct ratio either by the gas pressure regulated by the water pressure and / or by the partial pressure and current generated by the water flow in the flow channel.
  • the irrigation water can also be enriched with CO 2 and H 2 C0 3 for certain purposes if required.
  • the water pressure in the supply line can vary widely, e.g. B. vary between 1 bar and 7 bar, without this having an influence on the mixing ratio and the mixing accuracy.
  • the device is extremely easy to install and operate.
  • a device block 1 is provided for the device according to the invention, which has a connection 2 for connection to a conventional water supply line.
  • a supply line connection point is usually equipped with a shut-off valve.
  • a control chamber 3 is provided, into which the water enters from the line.
  • the inlet pressure of the water can vary within wide limits depending on the respective supply line, e.g. B. between 1 bar and 7 bar. Likewise, the respective temperature of the water removed can be very different.
  • the respective pressure of the water in the control chamber 3 acts on a membrane 4 which, via an actuating plunger 8, acts directly on the movable member 7 of the outlet and reducing valve of a CO 2 pressure vessel 6, e.g. B. acts on a conventional compressed gas bottle.
  • the pressure vessel 6 equipped with this valve only needs to be screwed in a sealing manner to the standardized connection of the device block 1 provided for this purpose. Such a valve closes automatically if no control pressure is applied to the valve member 7 from the outside.
  • a gas distribution chamber 5 is provided in the device block 1, which is connected to a gas chamber 10 via a throttle point 11.
  • a flow channel 13 is also provided in the device block 1, the inlet side 14 of which is in free flow communication with the control chamber 3.
  • the flow channel 13 is preferably straight and elongated and opens at its lower end at an outlet 28, which can be the direct outlet for the casting liquid, for. B. for filling watering cans or other containers.
  • a conventional garden hose or the like can also be connected to the outlet 28.
  • the flow channel 13 has a plurality of channel sections, the diameter of which progressively and abruptly increases. These injector nozzle-like sections are designated by 15a to 15c.
  • the flow channel in each case has a plurality of connection openings 17 which are in free flow connection with distributor channels 12, which in turn are connected to the gas chamber 10 are.
  • a feed pipe 25 projects into the flow channel 13 from above centrally and at a radial distance from the wall of the flow channel, which feed pipe is connected to a fertilizer supply for liquid fertilizer via a check valve or metering valve 26 and opens into the area of one of the injector nozzles 15a to 16b.
  • the mouth 27 lies in the area of the injector nozzle 15c.
  • the tap of the supply line to which device block 1 is connected is opened.
  • the water entering the device block 1 when opened fills the control chamber 3 and acts on the membrane 4 with the respective pressure.
  • the membrane 4 serving as pressure control is designed and dimensioned such that the reducing valve 7 is already in the control chamber 3 at a pressure of 1 bar of the pressure vessel 6 opens and C0 2 can flow out into the chamber 5 with a correspondingly reduced pressure in the control chamber 3.
  • the throttle device 11 ensures that the outflowing CO z gas cannot reach into the flow channel 13 until the water from the control chamber 3 has entered the flow channel 13 and fills it with its flow. When the flow channel 13 flows through, an abrupt decrease in pressure in the water flow forms in the individual diameter gradations.
  • the inlet cross section for the fertilizer can be set by means of throttling by means of throttling.
  • the feed pressure of the liquid fertilizer can be set directly or indirectly by the respective pressure in the control chamber 3.
  • a simple adjustment of the volumetric feed of the fertilizer per unit of water is achieved by allowing the pressure in the gas chamber 10 or 12 controlled by the control chamber 3 to act on the head space of the fertilizer supply or on the exterior of a flexible container which holds the supply.
  • a pressure-dependent supply of the fertilizer as well as the beginning and the end of the fertilizer supply is achieved in direct dependence on the opening or closing of the tap of the supply line.
  • the water pressure itself can also advantageously be used directly for emptying the fertilizer container.
  • the negative pressure prevailing in one or the other of the injector stages 33 in the flow channel can also be used to suck the fertilizer from a reservoir 38 via the suction line 36 and the riser line 39, depending on the pressure, while simultaneously drawing in the gas via the gas chamber 32, 34.
  • a separate injector stage can also be provided between the injector groups 33 and 35, which serves exclusively to suck in the fertilizer. 2 can also be used in conjunction with the pressurization of the fertilizer supply by the C0 2 gas pressure in the gas chamber 32, 34.
  • a device block 30 is again provided which combines all the essential parts and connections of the device and thus enables particularly simple control.
  • a water-soluble solid fertilizer can also be used instead of a liquid fertilizer.
  • the device block is designed so that the water flow through the flow channel 13 according to FIG. 1 rinses the solid fertilizer and releases a quantity of fertilizer corresponding to the quantity of water.
  • the valve 7 is practically a simple shut-off valve, which is held in its blocking position by the internal pressure in the container 6.
  • the internal pressure is z. B. 60 bar and can fluctuate depending on the temperature.
  • the area ratio of the sealing area of valve 7 and membrane area is z. B. about 1:60.
  • the container is shut off. If the water pressure acts on the diaphragm, this translates the pressure effect that it transmits to the valve by 60 times.
  • the valve opens, gas (C0 2 ) flows into chamber 5, from which the outflow, as already described, is throttled.
  • the membrane 4 translates all fluctuations in the water pressure and thus controls the CO 2 discharge as a function of it of water pressure and its fluctuations.
  • gas bubbles of oversized size will still be present when it exits the impregnation system.
  • These gas bubbles must be filtered out in such a way that they are supplied to the gas impregnation room itself so that they are not transported to the delivery point. This would mean that larger bubbles would escape into the atmosphere and the economy of gas use would be impaired.
  • This process can be prevented by installing a helix, but better by installing a meandering system that runs vertically in the system, with the highest point opening into the gas space. At this point, one or more outlet openings can be made that allow the lighter gas to escape at this upper point so that it can be fed back into the gas space of the injector system while the filtered and finely impregnated water is conveyed into the discharge zone.
