Description

The utility model relates to technology for processing powdered explosives (explosives) used for the manufacture of solid propellant products (SFP). The utility model is used in the technological process of manufacturing TTI for interphase transportation, as well as as a supply container for powdered explosives.

The most common closure for powdered explosives is a container in the form of a bag (Pozdnyakov Z.G., Rossi B.D. “Handbook of industrial explosives and means of explosion”, M.: Nedra, 1977, p. 151), which is the main delivery container for uncartridged explosives. However, it should be noted that for consumers, the use of explosives supplied in bags presents certain difficulties, especially when remotely introducing explosives into the technological process of manufacturing TTI. In this regard, consumers package explosives from bags into containers or other containers.

There is a known RF patent No. 2 233 257 for a method of packaging powdered explosives, in which this drawback is eliminated by packaging powdered explosives from bags into a container. However, it has a number of disadvantages in relation to its use for more powerful powdered explosives that have high energy characteristics.

The disadvantage is due to the fact that most powdered explosives, when poured and performing technological operations associated with the movement of particles relative to each other, are capable of generating static electricity, which at a certain potential level does not exclude sparking. Sparking contributes to the ignition of the dust-air mixture of explosives with the occurrence of rapidly spreading uncontrolled processes of explosion or detonation. To reduce the sensitivity to electric sparks of dust-air mixtures of powdered explosives, the air in the internal space of the apparatus is replaced with an inert medium (nitrogen or carbon dioxide). This is a prerequisite when using powdered explosives with high energy characteristics. Simultaneously with the supply of an inert medium, in order to prevent a dangerous build-up of pressure in the apparatus in the event of a fire, the casings of the apparatus are made with expulsion openings (surfaces).

A container for powdered explosives is known according to RF patent for invention No. 2 287 507 С06В 21/00, used for interphase transportation, and also as a consumable container, the design of which provides for the supply of an inert medium to the internal volume of the housing when processing powdered explosives. This container design was adopted by the authors as a prototype.

The container for powdered explosives, in accordance with the patent drawing, consists of a cylindrical-conical body 1 with a discharge pipe and a cover 2. The body is mounted on four wheels 4 and 5. The discharge pipe of the body 1 is closed by a spring-loaded valve 3, it is also equipped with a hinged cover 14. The valve represents is a composite structure assembled into a single whole. It is made in the form of a cone with a rod welded to it, to which an axis 28 is connected by means of a pin 29. In the cylindrical part, the housing 1 has a hatch 6 with a bigel cover 7, and in the conical part there is a pocket 11 for installing a vibrator. The cover 2 is equipped with a loading pipe 17 with a bigel cap 18, fittings 20 and 21 for supplying an inert medium to the internal volume of the housing 1, and in the center with a glass 25. A spring 24 is installed in the glass and, interacting with it, the axis 28 of the valve 3 is movable in the vertical direction. Spring 24 ensures that valve 3 is pressed against gasket 16 installed in the flange of the discharge pipe. The junction of the valve stem 3 with the axis 28, as well as the place where the axis interacts with the glass 25, is covered with a cover 33 made in the form of a corrugated tube.

A container for powdered explosives, in terms of its technical essence and the achieved technical result, is an essential feature of a container with bottom discharge, which is considered in the technical solution of the proposed utility model.

The disadvantages of the prototype include the absence of ejection openings on the container body, which in the event of an emergency are necessary to prevent a dangerous build-up of pressure inside the container body when the dust-air mixture of powdered explosives ignites.

The technical problem to be solved by the proposed utility model is to prevent a dangerous build-up of pressure inside the container body when the dust-air mixture of powdered explosives ignites, which will increase the operational safety of the container when processing powdered explosives, and the safety of the TTI manufacturing process as a whole.

The technical result is achieved by the fact that the container with bottom unloading consists of a vertical cylindrical-conical body, an upper cover, and a lower unloading pipe closed by a valve. In the cylindrical part of the housing there is an inspection window with a bigel lid, a vibrator is installed on the conical part of the housing, and the discharge pipe is equipped with a lid. The top cover is equipped with a loading hatch, two fittings for supplying an inert medium and a glass in the center with an elastic spring placed in it. The valve is held in the outlet of the discharge pipe by interacting with an elastic spring and a glass. The valve consists of a cone, a rod welded to it and an axis connected to it. The places where the rod interacts with the axle and the axle with the glass are protected by a cover made of a corrugated tube, the internal cavity of which is exposed to the atmosphere. The top cover of the housing is equipped with two diametrically opposite branch pipes, which have a total area equal to 20% of the area of the largest diameter of the cylindrical part of the housing. Each pipe is closed on top with a lid made in the form of an elastic membrane.

The proposed utility model is illustrated in Figures 1 and 2.

A container with bottom unloading consists of a vertical cylindrical-conical body 1 with a top cover 2 and an unloading pipe 3. The body is mounted on four wheels 5. The unloading pipe 3 is closed by a spring-loaded valve 16, and it is also equipped with a hinged lid 4. The cylindrical part of the body has a hatch 6 with a bead cap 7, and in the conical part there is a place for installing a vibrator 8. The cover 2 is equipped with a loading pipe 9 with a bead cap 10, fittings 11 and 12 for supplying an inert medium to the internal volume of the housing 1, a glass 15 in the center, as well as two diametrically opposed pipes 13 and 14, which are closed with covers made in the form of elastic membranes. The pipes 13 and 14 together with the covers perform the function of knockout openings, and the covers, made in the form of elastic membranes, are the weakened surfaces of the knockout openings. In the glass 15 there is a spring 21 and an axis 18 movable in the vertical direction, interacting with the spring and being an integral part of the valve 16. The spring 21 ensures that the assembled valve 16 is pressed against the gasket 23 installed in the flange of the discharge pipe 3. The valve is a composite structure , collected into a single whole. It is made in the form of a cone, to which a rod 17 is welded, and an axis 18 with a cap nut 22 is connected to the rod by means of a pin 19. The junction of the rod 17 with the axis 18, as well as the place where the axis interacts with the glass 15 in the internal cavity of the housing 1, is closed cover 20 in the form of a corrugated tube.

The operation of a container with bottom unloading is carried out as follows. The container is transported to the phase of preparation of powdered explosives, and it is placed under the loading device. In the initial position, the discharge pipe 3 is closed by valve 16 and cover 4. An inert medium supply line (nitrogen or carbon dioxide) is connected to fittings 11 and 12. Open the bigel cover 10 of the loading hatch 9 and connect the loading device. Through fitting 11, an inert medium is supplied to the lower part of housing 1 for a time specified by the technological documentation. Then the supply of inert medium is switched from fitting 11 to fitting 12, supplying the inert medium to the upper part of housing 1. At the same time, the product is loaded into the container body. After filling the housing 1 with the product, the supply of the inert medium is stopped and their supply lines are disconnected from fittings 11 and 12. The loading device is disconnected from the loading hatch 9 and the loading hatch is closed with a bigel lid 10. The container is transported to the TTI manufacturing building. Open the cover 4 of the unloading pipe 3. Place the container at the unloading position, fix it, and connect it to the docking unit of the receiver of the subsequent technological apparatus. A vibrator 8 is installed on the housing 1. The device for opening the valve is used to press the cap nut 22 of the axis 18, thereby moving the valve 16 away from the gasket 23 of the discharge pipe 3. Through the resulting annular gap, powdered explosives are poured from the housing 1 into the subsequent technological apparatus. If necessary, during unloading, turn on the vibrator 8. After unloading the container, the impact on the cap nut 22 of the axis 18 is stopped, the valve 16 returns to its original position. The vibrator 8 is removed and the container is removed from the docking station. Close the unloading pipe 3 with a lid 4. After which the container is sent for loading with a new portion of powdered explosives. Then the work cycle is repeated.

Thus, the presence in the design of a container with bottom unloading of knockout openings, made in the form of two pipes located on the top cover of the housing, which are closed on top with covers made in the form of elastic membranes, allows to prevent a dangerous build-up of pressure inside the container body when the dust-air mixture of powdered explosives ignites, which will increase the operational safety of the container when processing powdered explosives, and the safety of the TTI manufacturing process as a whole.

Testing of the proposed utility model in industrial conditions of the FKP "Perm Powder Plant", in the technological cycle of manufacturing TTI, confirmed its efficiency and performance.
