Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, an automatic continuous cleaning device for PVA dry spinning comprises a pump body 1, a heating barrel 3 and a cleaning assembly 10; the cleaning assembly 10 is connected with the spinning discharge port in a matching way; the inlet end of the pump body 1 is communicated with the heating barrel 3; the outlet end of the pump body 1 is connected with a delivery pipe 15; one end of the delivery pipe 15 far away from the pump body 1 is communicated and matched with the inlet end of the cleaning assembly 10; a water return pipe 24 is further communicated and extended on the heating barrel 3; one end of the water return pipe 24 away from the heating barrel 3 is connected with the outlet end of the cleaning assembly 10.

When equipment needs to be cleaned, the hot water barrel 3 is transferred to the position near a spinning box through a carrier such as a trolley, after a spinning part is dismounted, the cleaning assembly 10 can be mounted, then the conveying pipe 15 and the water return pipe 24 are respectively communicated and butted with an inlet and an outlet of the cleaning assembly 10, and then the pump body 1 is opened; the hot water inside the heating tub 3 enters the cleaning assembly 10 through the delivery pipe 15 and is poured into the interior of the apparatus to be cleaned, and is returned to the inside of the heating tub 3 through the return pipe 24, thereby completing the washing process.

A shunt pipe 25 is communicated with the conveying pipe 15; one end of the shunt pipe 25, which is far away from the delivery pipe 15, extends into the heating barrel 3; the shunt pipe 25 is provided with a regulating valve 22.

The shunt pipe 25 is used for adjusting the water supply rate of the delivery pipe 15 by controlling the opening degree of the regulating valve 22, so that more flexible parameter regulation and control can be performed according to the working condition requirement.

A delivery pump 19; one end of the delivery pipe 15, which is far away from the pump body 1, is communicated and matched with an inlet end of the delivery pump 19; the outlet end of the delivery pump 19 is communicated with the interior of the spinning discharge port 21.

The function of the delivery pump 19 is to further increase the delivery speed of the hot water on the basis of the pump body 1, as can be seen from fig. 1, the accelerated hot water firstly passes through the filter 20 to ensure the cleanliness of the water re-entering the equipment, and then enters the interior of the spinning discharge port 21, at this time, the inlet end of the spinning discharge port 21 is closed, and the hot water enters the interior of the equipment to be washed and cleaned and also flows back to the interior of the heating barrel 3 through the outlet end of the spinning discharge port 21; in addition, a pipeline of the dissolving kettle 17 of the spinning equipment is also provided with a connector for matching with the conveying pipe 15; the conveying pipe 15 can be flexibly communicated with three joints of the spinning equipment shown by dotted lines in the figure through a quick-assembly joint structure, so that the equipment is fully cleaned.

The filter screen cover 6 is used for isolating dirt entering the heating barrel 3 along with the backflow hot water, so that the hot water which does not contain solid impurities flows into the water suction pipe 5 all the time, and the circular cleaning effect is ensured.

The mesh surface of the filter screen cover 6 is of a hemispherical structure.

By setting the screen surface into a hemispherical surface, a larger filtering area can be provided under a certain volume as far as possible, and the probability that the filter screen cover 6 is blocked by solid impurities is reduced.

The bottom of the heating barrel 3 is of a contraction conical structure, and a drain valve 7 is arranged at the center of the bottom of the conical structure.

The bottom of the bucket with the conical structure can help the solid sediment in the bucket to be concentrated, reduces the influence on backflow water pumping, and can be efficiently discharged along with water flow from the drain valve.

In addition, as can be seen from fig. 2, a temperature measuring stainless steel pipe sleeve is arranged in the heating barrel 3 and used for conducting heat to measure the water temperature in the barrel, and the liquid level meter 14 is used for working together with the ball float valve 2, so that safer liquid level monitoring is realized.
