(54) MACHINE FOR WASHING UNITS AND PARTS

one

The invention relates to washing and cleaning equipment and can be used in various fields of thought.

A known machine for cleaning aggregates and parts containing a washing chamber, in which tubular collectors with nozzles are placed, a tank for washing liquid, a washing system pump with a suction pipe and a discharge pipe, the upper part of which is located above the upper longitudinal level of washing liquid in the tank and equipped with a device for connection with the atmosphere, a pump for washing liquid; from pordone to tank with suction and discharge piping. In the machine, the device for connecting the injection pipe of the flushing system to the atmosphere is designed as a floating valve. The connection to the atmosphere occurs when the pressure drops in the discharge pipe after the switch; no pump. This is necessary to prevent

rotational spontaneous overflow: washing liquid from the tank into the pan of the washing chamber after turning off the pump. When the machine is in operation, the floating valve rises under the action of the pressure of the washing liquid, closing the opening in the pipeline, and when the machine is turned off, it lowers and the connection with atmosphere 1 occurs.

The disadvantages of the known machine are the complexity and unreliability of the floating valve, having moving parts, working in a contaminated solution containing various

15 power on. Under these conditions, such disadvantages are possible. as the lack of tightness of the valve in the closed position (when the pump is running) and the valve sticking in the seat when not in operation; 20; In the first case you will be. the liquid flows through the valve to the outside, and in the second there will be a spontaneous overflow of the washing liquid 398 from the tank to the sump, with its overflow it will flow out. The purpose of the invention is to demonstrate the reliability of the machine operation. The goal is achieved by the fact that in a washing machine containing a washing chamber, manifolds with nozzles are placed in it, a tank for washing liquid, a pump connected to it through a suction line and to collectors via a discharge line and means for connecting the discharge line are located above the washing chamber with atmosphere, - the means for connecting the injection pipeline with the atmosphere has a throttling pipe mounted on the injection pipe, a casing attached to it, p Located in the casing above the free end of the nozzle, the reflector, the casing has a pipe fixed in the lower part for draining the liquid into the washing chamber and the holes drilled in its upper part above the reflector. FIG. 1 shows schematically the proposed machine, isometric; in fig. 2 — node X in FIG. 1. The washing machine contains a chamber 1 in which tubular collectors 2 with nozzles and a tank 3 with washing liquid, a pump 4 of a loudspeaker system with a suction 5 and a discharge 6 Pipelines, a pump 7 supplying liquids from a pallet to a tank with suction 8 and delivery 9 pipelines, pallet 1O. The discharge pipeline is made with an upwardly directed knee, the upper section 11 of which is placed above the upper limit level of washing fluid in the inlet 3. In the upper section 11 of the injection pipeline is installed a device 12 for connection with the atmosphere, filled in the form of a constantly open throttle nozzle 13, placed in casing. 14. Which is equipped with a liquid reflector 15 installed under the nozzle 13 and a tube 16 for draining the liquid into the washing chamber 1. Before the machine starts, fill the tray 1O and the tank 3 to a predetermined level with washing liquid. Then the pump 7 is turned on, and the liquid from the pallet 10 through the pipes 8 and 9 34 enters the tank 3. Next include the wet 4 washing systems, and the liquid from the tank 3 through the suction pipe 5 and the discharge 6 flows to the tubular pavisaM 2, from which it The nozzles are sprayed onto the object being washed. At the same time, a small amount of liquid flows out through the nozzle 13 and is reflected by the glue 15 through the discharge tube 16 to the washing chamber. In this case, the vacuum in the upper section of the pipe disappears and the spontaneous flow of liquid from the tank 3 to the pallet 1O stops, because the upper section 11 of the pipeline 6 is located above the upper longitudinal level of the liquid in the tank 3. Invention formula The machine for cleaning units and parts containing a washing chamber, collectors located there with soplami, a tank for a liquid located above the washing chamber, a pump connected to it by means of a suction pipe and with collectors by means of a discharge pipe a, and the means for connecting the injection pipe to the atmosphere, distinguishing a c. so that, in order to increase reliability, the means for connecting the discharge pipe to the atmosphere has a throttling nozzle mounted on the discharge pipe, a casing attached to it located in the casing above the free end of the nozzle a reflector, while the burner has a fortified liquid in the washing chamber and the holes made in its upper part above the reflector.
