Description

 The invention relates to cleaning equipment and can be used to collect various mechanical and liquid contaminants, including aggressive, fire and explosive.

 Known vacuum cleaner, and.with. 1447347, cl. A 47 L 5/18, 12/30/1988, which relates to cleaning equipment and can be used in various industries, in particular in the automotive industry, for cleaning dust and debris from the passenger compartment, trunk, engine compartment of a car, in mechanical engineering and when cleaning production sites , for cleaning parts of aggregate assemblies from mechanical dust and fine chips.

 This vacuum cleaner contains an inlet tapering nozzle and an outlet tapering nozzle installed in the pipe, having a constant cross-section channel passing into the diffuser, a nozzle for supplying a gas working medium to the inlet nozzle, a nozzle for removing debris and dust located between the nozzles and a filter.

 The vacuum cleaner operates as follows. The exhaust gas from the source of the working medium through the pipe enters the pipe, then into the tapering nozzle. Due to the narrowing of the nozzle, the air flow accelerates, thereby acquiring high pressure. The jet of high-pressure air leaving the nozzle enters the second nozzle. A vacuum forms in the cavity between these nozzles. When air leaves the first nozzle and enters the second nozzle, it entrains the dusty air mixture from the surface being cleaned into the pipe for suctioning debris and dust. Thus, the tapering part of the second nozzle enters the ejected air and the flow of the ejected dust-air mixture. Further, in the constant section channel of the second nozzle, two flows are mixed and their pressures are equalized with the creation of a vacuum. From the second nozzle, the dusty air mixture enters the diffuser, which allows to increase the vacuum in the vacuum cleaner by reducing the static pressure at the inlet of the second nozzle. The jet of dust-air mixture leaving the diffuser enters the internal cavity formed by the filter, in which part of the dust and debris are deposited. Part of the dust and debris can immediately exit to the designated area through the filter openings. The rest is deposited on the fine filter wall.

 The disadvantages of this vacuum cleaner include its inversion: with its help it is impossible to collect mechanical contaminants of large overall dimensions that will not pass through its nozzles, and such various liquid contaminants, including aggressive, fire and explosive ones.

 The closest in technical essence and the claimed universal ejector vacuum cleaner for collecting various contaminants, including liquid, is the "Ratnikova V.I. Universal ejector vacuum cleaner, patent RU 2119762, class A 47 L 5/18, from 10.10.1998 g ., selected as the closest analogue and containing a housing with a drain hose, pipelines with control valves and a filter for collecting mechanical impurities.

 The disadvantage of this universal ejector vacuum cleaner is its cyclical operation. For example, after filling the sealed housing with liquid, which is determined visually, you must manually close the valve through which compressed air flows to the ejector, manually open the valve in the drain hose and drain the liquid. At this time, the vacuum cleaner does not work, so it is not practical to use it when collecting large volumes of liquid contaminants, which must be collected as soon as possible.

 The objective of the invention is the creation of a universal ejector vacuum cleaner with continuous operation, with the ability to automatically drain the collected liquids during operation and install a filter to collect mechanical impurities, accelerating its replacement when necessary.

 The problem is solved due to the fact that in a universal ejector vacuum cleaner for collecting various contaminants, including liquid ones, containing a body with a drain hose, pipelines with control valves and a filter for collecting mechanical impurities, two containers are installed in it, the active nozzle of the ejector the first tank is connected through pipelines, its air distributor and air distributor mounted on the vacuum cleaner body with a compressed air line, the connection of the second nozzle's active nozzle to the main line with of compressed air through its air distributor and pipelines is blocked by an air distributor of the first capacity, the drain pipelines of these containers are connected through the check valves to the internal cavity of the vacuum cleaner body, while the floats are movably mounted on the rods of the air distributors between their stops, placed in these containers and in the internal cavity of the vacuum cleaner body, pipelines are connected to their tanks through non-return valves and a quick-release filter to collect mechanical impurities, and passive nozzles ejected s are connected by pipelines with their tanks.

 This allows you to make the work of the universal ejector vacuum cleaner continuous, automatically drain the collected liquids from it during its operation, and if necessary, quickly replace the filter to collect mechanical impurities.

 The invention is illustrated in the drawing, which shows a General view of a universal ejector vacuum cleaner. A vacuum cleaner for collecting various contaminants, including liquid, aggressive, fire and explosive, contains a housing 1 on which an air distributor 2, containers 3 and 4 are mounted and fixed, an air distributor 5 is installed and fixed on the first one, and 2a is mounted on the second one. On the rods 6 of all these air distributors, between their stops 7, floats 8 are movably mounted, which are placed in containers 3, 4 and in the internal cavity of the vacuum cleaner body 1. In tanks 3 and 4, check valves 9 and 10 are installed, and in the intake hoses 11 and 12 a vacuum nozzle 13 and a filter 14 are installed to collect mechanical impurities.

 The passive nozzle of the ejector 15 is connected through a pipe 16 with a capacity of 3, and its active nozzle through a pipe 17, an air distributor 5, a pipe 18 and an air distributor 2 with a compressed air line 19. A passive nozzle of the ejector 15 is connected by a pipe 21 to a capacity of 4, and its active nozzle is connected with the compressed air line 19 through a pipe 22, an air distributor 2, pipelines 23, 24, and 18 are blocked by an air distributor 5. Drain hoses 25 and 26 of containers 3 and 4 are connected to the internal cavity of the vacuum cleaner housing 1, in which there are openings e 27 for communication with the atmosphere, and a drain hose 28, and control valves 29 are installed in the pipelines.

 The work of a universal ejector vacuum cleaner to collect various contaminants, including liquid, aggressive, fire and explosive, is as follows. Open the valve 29 in the compressed air line 19, from which compressed air through the air distributor 2, pipe 18, air distributor 5 and pipe 17 will enter the ejector 15, and it will pump air from the tank 3. When it reaches the required vacuum, open the valve 29 in the intake hose 11 and various mechanical impurities are collected with it, including liquid, which, having passed through the filter 14, are cleaned of mechanical impurities and then through the pipe 11 and the non-return valve 9 will enter the tank 3. After filling it, the float 8 floats up and, acting on the stop 7 of the rod 6, raises it to the upper position, and it will block the supply of compressed air through the pipe 17 to the ejector 15, which will connect the tank 3 with the atmosphere, and the liquid from it through the check valve 10 will merge into the internal cavity of the housing 1 of the vacuum cleaner.

 In this upper position, the stem 6 will open the supply of compressed air through the air distributor 5, pipe 23, air distributor 2a, pipe 22 to the ejector 15, which through the pipe 21 will pump air from the tank 4, and into it through the pipe 12 and the check valve 9 will come fluid to be collected.

 After draining the liquid from the tank 3, its float 8, acting on the stop 7, will lower the rod 6 to the lower position, and the cycle will be repeated, and the liquid from the tank 4 through the check valve 10 will merge into the internal cavity of the vacuum cleaner body 1, and may merge from it while working as intended for other containers.

 If the internal cavity of the vacuum cleaner body 1 is completely filled, its float 8 floats up, lifts the rod 6 to the upper position, which will block the supply of compressed air to the ejectors and the operation will be automatically stopped.

 After the end of operation, close the valve 29 in the compressed air line 19. If you need to replace the filter 14, remove the intake hoses from its fittings and install a new filter in its place. This will require very little working time. And the removal of mechanical impurities from the old filter can be produced during operation.

 The material from which the universal ejector vacuum cleaner is made depends on the chemical properties, collected, mechanical and liquid contaminants. And with the help of an ejector, it is now possible to lift polluted water from depths up to 8.5 meters.
