Abstract
The invention provides a novel pulse valve sound-proof device. The novel pulse valve sound-proof device comprises a pulse valve gas-distributing tank, lower flanges, upper flanges, a rubber sealing strip, a galvanized porous plate, low-carbon glass fiber cloth, sound-absorbing rock wool, an asphalt layer, a metal housing, a hinge, a bolt assembly and a handle, wherein the metal housing is square in appearance, the handle is welded on the metal housing, and the upper flanges are welded at left and right sides of the metal housing; lower flanges are correspondingly welded at left and right sides of the pulse valve gas-distributing tank; the rubber sealing strip is cushioned between the upper flange at the left side and the lower flange at the left side; the upper flange at the left side and the lower flange at the left side are in locking connection through the bolt assembly; and the upper flange at the right side and the lower flange at the right side are connected through the hinge. According to the novel pulse valve sound-proof device, a flexible substrate layer, namely low-alkali glass fiber cloth is pasted on the galvanized porous plate, the metal housing is of a double-layer stainless steel structure, the asphalt layer coats at the inner side of the metal housing, and the sound-absorbing rock wool is arranged between the metal housing and the galvanized porous plate for eliminating noises. The novel pulse valve sound-proof device adopts a layered structure, is good in noise reducing effect, is simple in structure, is light in weight and is convenient to mount; and noise hazards generated during ash clearing of a pulse valve are effectively solved.
Description
Technical field
The present invention relates to sack cleaner sentinel valve, be specifically related to a kind of Novel pulse valve sound arrester.
Background technique
Along with country requires more and more tighter to fume emission, the requirement tackling all kinds of dusting apparatus is mutually also more and more higher, sack cleaner is a kind of dusting apparatus that dust removal efficiency is higher, when dust-containing airflow enter sack cleaner by filtrate after, dust is by detention, gas is purified, after the resistance on filtrate reaches certain numerical value, carries out jetting deashing by means of pressurized gas mode.Conventional jetting deashing system is primarily of sentinel valve, point gas tank, injection tube and pipe joint composition, and sentinel valve is the critical component of jetting deashing, is undertaken controlling, can open and close high-pressure air source instantaneously and produce the diaphragm valve of pulse by solenoid valve.During work, diaphragm opens and closes very fast, and air release rapidly, forms unexpected outburst, now diaphragm vibrations friction also can produce very large noise, and the harm brought to the mankind is very large, if long-time operation under the environment of the noise of high-decibel, can hearing be damaged, affect health.
So although sack cleaner can well control pollution of atmosphere, also create noise pollution hazard simultaneously.In prior art, usually adopt simple protective housing to isolate minimizing noise, but tentatively can only play defening effect, the requirement to the comprehensive obstruct of noise can not be met completely.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, provide a kind of Novel pulse valve sound arrester for sack cleaner, adopt hierarchy, not only excellent noise reduction effect, and structure is simple, lightweight, easy for installation, efficiently solve the noise hazard that sentinel valve produces when deashing.
The technological scheme that the present invention adopts for its technical problem of solution comprises: sentinel valve divides gas tank, lower flange, upper flange, rubber weather strip, zinc-plated porous slab, low alkali glass fiber cloth, sound absorption rock wool, pitch prill layer, metal case, hinge, bolt assembly, handle.
Metal case outward appearance is square, semi-circular or ellipse, and it is welded with handle, and the left and right sides is welded with upper flange;
Sentinel valve divides gas tank left and right sides correspondence to be welded with lower flange; Be lined with rubber weather strip between left side upper flange and lower flange, and connected by bolt assembly locking, right side upper flange and lower flange pass through hinge-coupled.
Described zinc-plated porous slab is stained with flexible substrate layer low alkali glass fiber cloth, the noise of generation is first weakened by the zinc-plated porous slab of internal layer and low alkali glass fiber cloth; Described metal case is double-layer stainless steel structure, and inner side scribbles pitch prill layer, has further sound deadening; Be provided with the rock wool that absorbs sound between described metal case and zinc-plated porous slab, be used for abating the noise.
The sound arrester of sentinel valve and sentinel valve divide gas tank to form enclosed construction, have removed bolt assembly, can be opened an account by handle and be closed sound arrester.
Beneficial effect of the present invention is:
1, the sound arrester of sentinel valve adopts hierarchy, and soundproof effect is good, is isolated from the outside by sentinel valve, decreases noise pollution during sentinel valve work.
2, the sound arrester of sentinel valve adopts hinge structure easy accessibility, and metal case adopts double-layer stainless steel structure, prevents routine use corrosion.
3, the sound arrester of sentinel valve can protect rapid wear electromagnetic valve coil exposed above sentinel valve effectively.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention; Fig. 2 is the left view of Fig. 1.
In figure: 1 for sentinel valve divide gas tank, 2 for lower flange, 3 for upper flange, 4 for rubber weather strip, 5 for zinc-plated porous slab, 6 for low alkali glass fiber cloth, 7 for sound absorption rock wool, 8 for pitch prill layer, 9 for metal case, 10 for hinge, 11 for bolt assembly, 12 for handle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
This concrete enforcement provides a kind of, comprising: sentinel valve divides gas tank 1, lower flange 2, upper flange 3, rubber weather strip 4, zinc-plated porous slab 5, low alkali glass fiber cloth 6, sound absorption rock wool 7, pitch prill layer 8, metal case 9, hinge 10, bolt assembly 11, handle 12.
Metal case 9 outward appearance is square, it is welded with handle 12, and the left and right sides is welded with upper flange 3; Sentinel valve divides gas tank 1 left and right sides correspondence to be welded with lower flange 2; Be lined with rubber weather strip 4 between left side upper flange 3 and lower flange 2, and lock connection by bolt assembly 11, right side upper flange 3 and lower flange 4 are connected by hinge 10.
Described zinc-plated porous slab 5 is stained with flexible substrate layer low alkali glass fiber cloth 6, the noise of generation is first weakened by the zinc-plated porous slab 5 of internal layer and low alkali glass fiber cloth 6; Described metal case 9 is double-layer stainless steel structure, and inner side scribbles pitch prill layer 8, has further sound deadening; Be provided with the rock wool 7 that absorbs sound between described metal case 9 and zinc-plated porous slab 5, be used for abating the noise.
The sound arrester of sentinel valve and sentinel valve divide gas tank to form enclosed construction, have removed bolt assembly 11,12 can open an account by shaking hands and close sound arrester.
