Embodiment Construction

[0013] Such as figure 1 As shown, one end of the cold wind nozzle 1 is connected with the threaded connection of the sound-absorbing antifreeze cover 2 with M16. The sound-absorbing antifreeze cover 2 is processed by the phenolic resin stick. The size of the first expansion lumen is φ24×20, the second expansion lumen is φ18×15, the third expansion lumen is φ14×14, the dimensions of the constriction lumens connected to them are φ20×15, φ16×15, and the outlet diameter is φ8 , the outlet end is fixed with a ring made of nickel-chromium alloy sheet with screws, and the ring is connected to the low-voltage power supply, which is the resistor sheet 3, and the current it passes is a 12V DC current for the width adjustment, and the width time varies with the resistance sheet 3 temperature, under normal circumstances the temperature can be maintained in the range of 70 ℃ ± 1 ℃.

Abstract

The present invention relates to a noise-suppressing anti-icing cover, related to the refrigeration and cryogenic technology, and is characterized by that a cover whose interior possesses several concave and convex alternated hoods with ring grooves are mounted on the head portion of low-temp. spray nozzle so as to eliminate noise, and the front end of the cover is equipped with a resistor disc which is connected low-voltage electrode so as to produce heat for eliminating ice plugging.

Description

[0001] Field: [0002] The title of the patent of the present invention is a sound-absorbing anti-freeze cover, which belongs to the technical field of refrigeration and low temperature. Background technique: [0003] In the field of refrigeration and low-temperature technology, it is often encountered that the low-temperature gas is discharged to the atmosphere. If the temperature of the gas is lower than the frost point of the air, the water vapor in the air will gradually gather around the exhaust port to form frost, and finally The phenomenon that the exhaust port is blocked by icicles makes the exhaust port unable to continue to exhaust, and the exhaust port will also generate a lot of noise due to the high-speed discharge of gas. The measures currently taken are: [0004] 1. Regularly hammer the exhaust port to remove the icicles condensed outside the port. [0005] 2. Wrap the resistance wire on the exhaust port, and prevent ice blockage by energizing and antifreezing....
