Description

The invention relates to process equipment for cleaning hollow articles, preferably filters of various classes, made of fused powder or microballs, as well as products from porous structures.

The purpose of the invention is to expand technological capabilities and improve the quality of cleaning.

FIG. 1 shows a diagram of the device; in fig. 2 - container with items; in fig. 3 shows section A-A in FIG. 2

The device comprises a stepper conveyor 1 for moving the containers 2 with the products to be cleaned at the positions of washing and drying. In each container 2 one or several products may be placed depending on their sizes. The container is made of two hollow parts 3 and 4 that are tightly interconnected and have nozzles 5. Part 3 of the container is equipped with a partition 6 embedded in it with openings 7 for accommodating the cleaned articles 8 with sealing rings 9. Round insert 10 with openings 11 holds 8 in slots and is pressed against part 4 of the cassette. Nozzles 12 for supplying a detergent iia of the product and nozzles 13 for supplying a drying agent to the products are mounted on brackets 14, which are mounted with the possibility of axial movement of nozzles 12 and 13 in the horizontal plane by drives 15.

Each nozzle 12 with a flexible tube 16 connects with its valve 17-union “a. The nozzle “b of this spool is connected to the connector” and an additional spool 18, and the fitting “c” to the displacement chamber of the ejector 19. The fitting “b of the spool 18 by tube 20 is connected to the cavity of the container 21 for the heated washing liquid, and the fitting“ c ”to the pipeline 22 supply of compressed gas having a filter 23.

Each nozzle, 13 positions of the device life, is connected with a flexible tube 24 of its spool 25, and a compressed gas supply pipe 26 with a filter 27 is connected to its brush nozzle. The ejector mixing chamber 28 is connected to the fitting. Sponge-gas heating and drying device (not shown).

The active nozzles of the ejectors 19 and 28 are connected to a source of compressed air through the appropriate valves. The outputs of all ejectors are connected to the trunk of one cyclone 29.

The device works as follows.

The containers 2 are loaded with the products to be cleaned and placed on the feeder (not shown) on the stepping conveyor 1. The containers 21 are filled with a washing liquid, which is heated. Open the source of compressed air for operation

tori 19 and 28. Open the source of compressed heated and dried gas, let the control device (not shown).

The step conveyor 1 alternately feeds the containers to the washing position (nozzle 12), the drying position (nozzle 13), and sends them to a hopper (not shown). Before installing containers 2 at the position of washing and drying, the actuators 15, according to a signal from the control unit, separate the brackets 14, and with them the nozzles 12 and 13 in opposite directions for the passage of the containers 2. Then the nozzles 12 and 13 are closed, connected to the nozzles of the containers .

After the container 2 is installed on the washing position, the left and right ejectors 19 begin to suck the air out of the container 2, and with it the dust-like contaminants and throw them into the cyclone 29. Then the control device switches on the electromagnet of one of the spools L7, for example in it, the channel "ab" and the channel "ab" connected to it, "an additional spool 18 under the action of the right ejector 19 from the left tank 21 through the tube 20 is sucked into the left cavity of the container 2 heated liquid that rushes through Aly of the cleaned products into the right part of the container 2 and through the right nozzle 12, the right flexible tube 16 enters the mixing chamber of the right ejector 19, from where it is carried out into the cyclone 29 together with the inducing air stream to the cyclone 29. After the set time has elapsed, the electromagnet of the left additional spool 18 turns on In the formed channel of the channel, ac from the source receives heated gas under pressure, while in the channel cavities of the spools 17 and 8, the flexible tube 16 and the left cavity of the container 2 filled with washing liquid, e occurs sparging and a gas-liquid mixture is formed, which, under the pressure generated by the gas pressure and under the action of the suction force of the right ejector 19, breaks through the channels of the products being cleaned, exfoliates and carries away the contaminants into the cyclop 29. When the gas-liquid mixture that has formed is consumed, the spool electromagnet 18 is turned off and a channel is formed there again which is supplied with a portion of the washing liquid to the cassette. After the electromagnet of the spool 18 is turned on again, a heated gas is supplied through the newly formed channel "Al" to produce liquid sparging. This process is repeated many times. Then the electromagnet of the left spool 17 is turned off and a channel "ac is formed in it, and the electromagnet of the right valve 17 is turned on, the channel" ab is formed in it, and the washing

the liquid from the right tank 21 under the action of the left ejector 19 sucks in the container 2 washing liquid. The electromagnet of the right additional spool 18 is turned on, and a heated gas is directed to the cassette 2 through its channel "ac," which barges the washing liquid, forming a gas-liquid mixture. Under gas pressure and due to the suction effect of the left ejector 19, the gas-liquid mixture passes through the channels of the products being cleaned in the opposite direction, exfoliating contaminants in the product channels and carrying them into the cyclone 29. This process, as in the first case, is repeated many times.

the product in the opposite direction to the left ejector 28, the moisture is taken out again in the cyclone 29. These operations are repeated many times until the products are completely dried. At the end of drying, the container with the dried products is sent to the hopper. During drying, the next product cartridge is washed.

Claims (2)

1. An apparatus for cleaning hollow or porous articles, comprising a conveyor for feeding articles into a cleaning zone located on both sides of the transnorter Thus, the process of alternating 15 opposing nozzles for supplying detergent to the container 2 of washing liquid and agent for products and opposite nozzles for supplying drying agent to the product, and a distribution system, and supplying the washing and drying agent to the nozzles, characterized in that in order to expand the technical gas in opposite directions is repeated many times.
