Description

FIELD OF TECHNOLOGY

The invention relates to the construction of a film mixer container, which is designed to obtain the target product from the individual components. The container consists of several (by the number of components) sealed film chambers interconnected through a removable partition and in which the original components are stored until they are mixed. The mixing of the components to obtain the final product is carried out in a common chamber, which is formed by removing the sealed septum by shaking or shaking in a gaseous medium.

The container also contains a device for extracting the final product from it. Products that are expedient to receive in such a container include household and industrial chemicals, such as two- or three-component systems for adhesives, putties, sealants, heat and cold protective foams, foam packaging, foam cushioning materials, small building and fodder mixtures, artificial soils agricultural and gardening, food and feed mixtures, medicines with a short shelf life for use in field and transport conditions, etc. Small shelf life and for others ready for use th products is an essential condition for the techno-economic for storage, manufacture and use of the inventive construction of the film container mixer. Important factors are the need for intensive manual mixing of the starting components in the field (non-workshop) conditions, the comparative high cost of the target products, which does not allow putting up with the loss of the product and viscous components on the walls of the rigid containers, high transportation costs for delivering products to places of consumption, simplicity and reliability of disposal empty container.

BACKGROUND

The invention is aimed at improving the design of the film container-mixer, which we announced earlier and which, in our opinion, is quite perfect in comparison with the world level of technology for manual intensive mixing of poorly compatible components in a film container.

The film container mixer consists of sealed film chambers interconnected through a removable partition (by the number of initial components to obtain the final product), which contain the initial components hermetically separated from each other. When removing the specified sealed walls of the film chambers form a common mixing chamber. Mixing is carried out in a gaseous medium under some excess pressure, which is necessary to give the elastic film common mixing chamber the necessary form stability (rigidity) so that the process of mixing the starting components is sufficiently intense so that mixing can be carried out by shaking or shaking. According to this invention, a gaseous medium is formed by filling at least one main section of the container with it, together with its source component or gas, filling the auxiliary section.

As shown by the experimental industrial use of this invention with all its perfection, it still has a drawback: it is necessary to store and transport (occupying the storage and transport volume) the intensive gas (air) used in the technology.

SUMMARY OF THE INVENTION

The objective of the invention is to improve the design of the film container mixer, known from our invention for the specified application for a patent of the Russian Federation and patents of foreign states. The improvement relates to a significant reduction in the storage and transport volume attributable to the process gas environment, as well as to a more accurate dosage of various (neutral or active) gaseous products supplied to the common chamber to give it the required form stability.

According to the invention, a film container-mixer, consisting of sealed film chambers interconnected through a removable baffle and containing the starting components to obtain the target product by intensive manual mixing in a gas medium by shaking or shaking in a common chamber, contains gas-emitting products as part of the main chambers. These products are capable of releasing gas into the common chamber for mixing the starting components before or at the time of mixing the starting components and in an amount that ensures the form stability of the common chamber and manual mixing of the starting components by shaking or shaking.

Gas-forming products are selected from the group of thermally degradable substances or mixtures thereof, low-boiling substances or substances interacting with each other with the release of gaseous products.

Or the container contains additional sealed chambers. In these additional chambers, there are separately substances capable of forming gaseous products in their quantity in an amount that ensures the shape stability of the common chamber and manual mixing of the starting components by shaking or shaking. Additional sealed chambers are interconnected and with a common mixing chamber through removable sealed partitions.

Or, as an option for solving the problem, the mixer container contains one additional sealed chamber, in which there is a thermally decomposable or low boiling (low boiling) substance, which ensures the release of gaseous products in an amount sufficient to impart, when heated, the specified additional sealed chamber (and its corresponding substance) the general chamber of dimensional stability and manual mixing of the starting components by shaking or shaking. An additional camera is connected through a removable partition with a common camera. Additional cameras can be located both at the end of the container, in its device for extracting the target product, and between the main cameras, as well as inside one of the main cameras. As the starting gas-forming substances for filling the main or additional sealed chambers according to the invention, practically any pair of solid or liquid substances can be used, when mixed, gaseous products (separate gas or gas mixture) are released under the conditions of using a film container both at normal temperature and at high or low temperatures. The limitation is the permissible chemical activity of the gas-forming substances and the gas formed from them. The gas and the starting materials for its production should not react with the starting components for the production of the target product and with the target product itself, if this interaction is unacceptable or undesirable or if the container does not contain the means described below to prevent liquid gas-emitting products from entering the common chamber. On the other hand, if it is advisable to use an active gas-generating system, then you can choose it based on the tasks. If necessary, excipients such as catalytic or inhibitory systems that promote or inhibit gas evolution, as well as surfactants, can be added to the starting materials to obtain gaseous products.

Known substances having a decomposition (decomposition) temperature ranging from + 40 ° C to the temperature of a possible heating of the film container (of the order of + 80 ° C) can be used as thermally decomposable substances. The same temperature range should be observed for low-boiling substances if the additional tight chamber or the main chamber (chambers) of the film container are filled with such a low-boiling substance.

As pairs of components for the formation of gaseous products, you can use a relatively strong acid and salts of carbonic acid (carbonates), or strong acid and a powder of a metal (mainly aluminum), or compounds with free isocyanate groups (isocyanates and polyisocyanates) and aqueous systems (water) and others selected by well-known specialists in gas-generating chemical reactions.

Inorganic substances such as ammonium carbonate (decomposition temperature about 58 ° C) and acidic ammonium carbonate (decomposition temperature in the range of 40-60 ° C) and others, as well as organic non-heat-resistant, can be used as thermally decomposable substances for the formation of gaseous products with the above restrictions. compounds with the above decomposition temperature. The list of compounds with a decomposition temperature from 40 to 80 ° C is sufficient for practical use (see Chemistry Handbook. Volume 2 - Chemistry. Leningrad, 1967).

As low-boiling substances for the formation of their gas phase, you can use a wide range of organic substances with a boiling point in the specified range. These are hydrocarbons (hexane / 67-68, ethyl acetate / 70-80, cyclopentane / 49-50, dichloromethane / 40-42, etc.), ethers and esters (ethyl acetate / 70-80, tetrahydrofuran / 66-68 , formalglycol / 65-85, etc.), aldehydes (acetone / 55-56, vinyl acetate / 72-73, ethyl acetate / 74-80, dichloromethane / 40-42, carbon tetrachloride / 75-78, etc. ), as well as organic compounds that do not have a strictly defined composition such as petroleum ether / 40-80. Alcohols - methanol (64.5) and ethanol (78.0) are also applicable for these purposes. The numbers in this paragraph indicate the boiling range of the listed technical grade substances. A list of such compounds can be found in the Chemist's Handbook mentioned above (volumes 1-6).

The amount of substances used for the formation of gaseous products (gases) is determined on the basis of the required volume of gas, which provides the common chamber with the necessary form stability to carry out the process of manual intensive mixing of the starting components by shaking or shaking. The experiments showed that the required volume of gas in the common chamber for these purposes is from 0.1 to 1.0 parts of the total volume of the mixed main components used to obtain the target product.

The design of the mixer film container (which we arbitrarily call “Boltushka-M"), created in accordance with the present invention, makes it possible to reduce the storage and transport volume due to the multiple difference in the volume scales of gaseous and solid (or liquid) products. For solid and liquid products, from which gas is formed according to the invention, a significantly smaller volume is required for their storage and transportation in a film mixer container. The dosage accuracy and the assortment of gases used to form the overall stability of the component mixing chamber are also improved.

In order to guaranteedly prevent undesired products from entering into the common chamber (manual mixing of the starting components) from which gas is formed in additional chambers (chamber), the total volume of the gas-forming excipients mixing chamber is set no less than the volume of gas used. Under these conditions, gas is supplied to the common chamber after the gas-emitting products have been completely consumed. An option to solve this problem of preventing unwanted products from entering the common chamber is to connect the common chamber with additional chambers (camera) in the form of a “return funnel” with an expanding part towards the common chamber, which has a removable (brittle film) baffle plate at its narrow end.

A sufficiently practical embodiment of the inventive container is the design of which additional chambers (camera) are located in the device for extracting the target product, made in the form of a tapering part of the common chamber, and are separated from the common chamber through a removable partition.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 - shows a schematic diagram-sketch (in plan I and side view II) of a film mixer container of the claimed design with two main sealed chambers (1 and 2) and two additional sealed chambers (3 and 4). Chambers 1 and 2 contain separately (separately from each other) the main components (A and B), when mixed in a common chamber (1 + 2), they form the target product. Additional sealed film chambers 3 and 4 contain separately auxiliary substances (B and D), when mixed in an additional chamber (3 + 4) they form a gaseous product. The latter, when removing the additional partition (8), enters the common chamber (1 + 2) and serves to carry out the intensive manual manual mixing of components A and B by shaking (when mixing soluble powder and liquid) or shaking (when mixing combined liquids and / or large masses, up to 12 kg, various substances). The shape stability of the main common chamber (1 + 2) is achieved due to the corresponding amount of the gaseous product being in it under some excess pressure supplied from the combined chamber (3 + 4), or by folding the end part of the film container from the side of additional chambers to create the necessary gas overpressure. The folding process is described in detail and illustrated by us in this previous application.

And this device itself is made in the form of a tapering part of a common chamber. The common chamber (1 + 2) is connected here with additional chambers (3 + 4) using an auxiliary device (11) made in the form of a “return funnel” (height h) with an expanding part towards the common chamber (1 + 2), and having on its narrow end facing the additional chambers (3 + 4), a removable partition (a destructible film partition-plug). The execution of the gas outlet channel in the form of a return funnel with a baffle allows, if necessary (when the volume of the additional chambers is less than the volume of the generated gas) to prevent liquid gas-forming substances from entering the common chamber (1 + 2).

1 and 2 are the main sealed film chambers containing separately the main components A and B. The chambers are connected through a partition (7) that is removable from the outside by mechanical or brittle (capable of breaking from the inside by some excess pressure).

DETAILED DESCRIPTION OF THE INVENTION

Since the authors of the present invention have already organized a pilot industrial production of film container mixers of the basic design in accordance with the invention according to our application No. 2006107426/12 of 03/10/2006, the implementation of the present invention does not represent any complicated engineering task. All source materials are available on the Russian market. The technology for the production of film containers has been tested. It is also easy to add one or more additional film chambers containing auxiliary substances to the completed construction of the film container.

As an experiment, we have made prototypes of film containers-mixers of a standard series for the production of a polyurethane reaction system, which is designed to insulate the joints of heat pipes directly in the field of their laying.

The prototype film mixer container of the claimed design is schematically shown in Figure 1. The dimensions of the container filled with components A (polyester component) and B (isocyanate component containing 30 wt.% Free isocyanate groups) were (excluding two additional chambers): length - 530 mm and a width of 125 mm with a filling volume of its main chambers (1 and 2) with component A - 0.122 l and component B - 0.184 l.

Additional chambers (3 and 4) were made in size: length (along the main axis of the container) - 10 mm and width - 125 mm. The removable partitions (8 and 9) were made brittle by spot applying paint to the welded surfaces of a 3-layer flexible material (polyethylene-aluminum foil-polyethylene terephthalate) in the places where the partitions were formed. As an auxiliary substance for the formation of gaseous products, component B and water (with the addition of a tertiary amine and a surfactant, also included in component B) were placed separately in additional chambers in an amount of 4.5 grams and 0.7 grams to form 0 , 35 liters of carbon dioxide.

Obtaining foam was carried out by the following technological methods.

By pressing on the chamber 4 with his hands, the sealing partition 9 was opened (eliminated) and by mixing the excipients from the chamber 4 into the chamber 3 and back they achieved mixing of these substances and the release of carbon dioxide. Then the mechanical clamp 7 separating the chambers 1 and 2 was removed, and at the same time the partition 8 was opened. As a result, the common chamber (1 + 2) was filled with carbon dioxide under some excess pressure. And then, by agitating the contents (in the formed form-stable common chamber), the required mixing of components A and B was achieved. The resulting reaction mixture was released out through the nozzle 5, having previously removed the mechanical clamp 6. The polyurethane foam with an apparent density of about 60 kg / m ^{3 was} obtained. The same experiment was carried out under conditions when the general chamber for mixing auxiliary substances (3 + 4) had a volume of 0.35 L (dimensions - 125 mm × 60 mm) so that all the carbon dioxide formed in it until it is discharged into a common chamber (1 + 2) filled the chamber (3 + 4), guaranteeing a complete conversion of the initial gas-forming substances (isocyanate and water).

Another experimental example was carried out by the inventors to obtain a carbonated sweet drink, for which the starting components were water with the addition of baking soda and the second component was a mixture of granulated sugar and citric acid. Gas-forming substances were drinking soda and citric acid. An additional camera was not used, as gas-forming substances were contained in the main chambers and their interaction was carried out at the time of mixing all the components - water, baking soda, granulated sugar (the latter required its dissolution by shaking the contents of the common chamber) and citric acid.
