Detailed Description

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The no-clean flame arrester disclosed in the embodiment comprises a shell, as shown in fig. 1-3, and the shell is composed of an upper flange 7 and a lower flange 7, a flame-retardant cavity 2 is arranged between the upper flange 7 and the lower flange 7, and a shell 3 is arranged outside the flame-retardant cavity 2. A gland 4 is arranged on the shell 3. An air inlet is arranged on the upper flange 5, and an air outlet is arranged on the lower flange 7. A fire retardant core 1 is arranged in the fire retardant cavity 2. Cleaning devices are further arranged on two sides of the shell 3.

The cleaning device comprises a frame 9 to which a rotating handle 8 is mounted. The frame 9 is arranged in the fire retardant cavity 2, and the rotary handle 8 protrudes out of the shell 3 of the fire retardant cavity 2. The housing 3 is provided with a mounting groove 10 for receiving the rotary handle 8. The rotating handle 8 is of a T-shaped structure.

A plurality of cleaning strips 11 which are uniformly distributed are arranged in the frame 9. Through the arrangement, the extra cleaning device is arranged, the fire retardant core 1 blocked by impurities is cleaned through the cleaning device, the cleaning is not required to be frequently disassembled, the labor intensity of workers is greatly reduced, and the practicability is improved.

The surface of the cleaning strip 11 on the side away from the housing 3 is provided with cleaning bristles or cleaning soft teeth. Through above-mentioned setting, clean hair or clean soft tooth can get into the gap of back-fire relief core 1, clear up the spark arrester more meticulously, promote clean effect.

The fire retardant core 1 comprises a plurality of corrugated filter sheets which are stacked along the radial direction of the fire retardant cavity 2. Through the arrangement, the corrugated filter element is made of stainless steel, copper-nickel alloy, aluminum or aluminum alloy. The corrugated flame arrester can stop deflagration violent flame, bear corresponding mechanical and thermal effects, has small flow resistance and is easy to clean and replace.

Both the firestop core 1 and the frame 9 are round. The diameter of the firestop core 1 is smaller than the diameter of the frame 9. Through the arrangement, the cleaning range of the cleaning device can cover the whole fire retardant core 1.

The thickness of firestop core 1 is less than twice the length of the cleaning bristles or cleaning soft teeth. Through the arrangement, the cleaning range of the cleaning hair or the cleaning soft teeth on the cleaning strips 11 at the two sides can cover the surfaces of all the filter sheets in the fire retardant core 1.

A detachable sealing ring 12 is arranged between the rotating handle 8 and the shell 3 of the fire retardant cavity 2. The seal rings 12 are provided on both sides of the T-shaped rotary handle 8 between the rotary handle 8 and the housing 3.
