AI Technical Summary

Technical Problem

When the material hopper is opened, air enters the hopper, causing the ultrafine denier monofilament chips to come into contact with air, resulting in a fluorescent reaction and affecting product quality.

Method used

Design a protective device to prevent fluorescence reaction of ultra-fine denier monofilament slicing. By linking the feed valve and the control valve, a vacuum pump is started to evacuate the silo, reducing the amount of air entering and preventing the slices from contacting the air.

Benefits of technology

This effectively prevents the slices from becoming too moist after contact with air, reduces the generation of fluorescence reactions, and ensures product quality stability.

Description

TECHNICAL FIELD

[0001] The utility model relates to polyamide spinning production technical field especially relates to a kind of super fine denier monofilament stock bin slice fluorescence reaction protection device. BACKGROUND

[0002] The characteristic of the slice of super fine denier monofilament is easy to absorb moisture, and the production stability and quality reliability are affected after being exposed to air and easily absorbing moisture, so vacuum packaging is used during storage. However, during use, a bag of slices needs to be poured into a storage tank for storage and use, and the slices are protected by nitrogen in the stock bin. The storage tank is a large closed iron cylinder, with a feed inlet at the top and a screw extruder at the bottom. The slices fall vertically into the extruder. The storage capacity of the slices needs to be added in time according to the usage. When a part of the slices is used, the slices need to be replenished, and the feed inlet valve needs to be opened to add the slices. It takes 10 minutes to add a bag of slices. During the feeding process, air will be brought in, and nitrogen will be lost when the stock bin is opened. When the slices are in contact with air for a long time, the product produced under the irradiation of ultraviolet light will produce a circle of fluorescence reaction, affecting the product quality. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a super fine denier monofilament stock bin slice fluorescence reaction protection device that can better protect the slices when the stock bin is opened.

[0004] The utility model is implemented as follows:

[0005] The utility model provides a kind of super fine denier monofilament stock bin slice fluorescence reaction protection device, including stock bin, the top of the stock bin is provided with feed inlet, the feed inlet is provided with feed valve, the top of the stock bin is also provided with suction port, the suction port is connected with vacuum pump by pipeline, the device also includes the control valve for controlling vacuum pump start-stop, the feed valve and control valve are connected with control system, feed valve and control valve are linked, and when the feed valve is opened, the control system starts vacuum pump by control valve.

[0006] Further, the suction port is arranged at a position close to the feed inlet.

[0007] The utility model has the advantages that when the feed valve is opened, the vacuum pump is automatically started to vacuum the stock bin, and the vacuum device is automatically stopped when the stock bin valve is closed. By vacuuming, air is prevented from entering the stock bin, reducing the problem of high moisture content after the slices come into contact with air, and preventing air from entering to cause fluorescence reaction of the product under ultraviolet light. BRIEF DESCRIPTION OF DRAWINGS

[0008] The utility model will be further described with reference to the drawings combined with embodiments.

[0009] Figure 1 It is the structure schematic view of the silo slice fluorescent reaction protection device of the utility model.
