Description
Technical field
The utility model is related to a kind of explosion-proof dust arrester.
Background technology
There is airborne dust during metal dust (aluminium powder etc.) working process, easily trigger fire or explosion accident, jeopardize personnel
Safety.Therefore, strong demand is there is in this area for explosion-proof dust arrester.
Utility model content
The purpose of this utility model is to provide a kind of explosion-proof dust arrester.Entered using this dust arrester from production and processing source
Row dust suction, can reduce and eliminate dust hidden danger, it is ensured that safety in production.
Explosion-proof dust arrester of the present utility model includes offering the grid type dust shield of the thin mouth of strip, by cleaning shaft
The dedusting tank that is connected with grid type dust shield, the filter being arranged in dedusting tank, the detonating fusee covered installed in dedusting tank, set
The ash-removing valve door and the air-introduced machine by pipeline connection dedusting tank in dedusting pot bottom are put, wherein, it is provided with cleaning shaft
Flame proof valve.
Further, grid type dust shield is stainless steel flat casing, and dust suction face arc opens up the thin mouth of strip.
Further, all turnings of cleaning shaft are designed as streamlined.
Further, flame proof valve is convertible flame proof valve, and under dust arrester normal operating conditions, flame proof flap is in negative pressure
Kept it turned under airflow function；Under static state, flap is closed under its Gravitative Loads, and is close to flame proof valve inlet side
Sealing surface on.In normal operation, if detonation or blast occur in flame proof valve front end, pipeline forefront pressure increase, air-flow is anti-
To flowing, flame proof valve is closed.Flap is close on the sealing surface of entrance side under blast pressure effect, and self-locking mechanism is locked automatically
Only, explosive flame and pressure-wave propagation are prevented.
Further, dedusting tank is the vertical enclosed tank body of stainless steel, inner fixed filter.
Further, filter is using the cylindricality or conical filter of non-woven fabrics filtrate, and the top in dedusting tank is used
In Chalk-dust filtering particle, gas passes through unaffected.
Further, detonating fusee is covered installed in dedusting tank, both ends open, upper end connection air, lower end connection dedusting tank
Venting of dust explosion piece is provided with inside, pipe.
Dust arrester operation principle is as follows：Under air-introduced machine working condition, with the discharge of large quantity of air, grid type dust suction
Negative pressuren zone is formed around cover.After airborne dust (gas powder mixture) enters dedusting tank through dust shield, pipeline, flame proof valve, flow velocity diminishes, and makes
A portion powder is fallen into dedusting pot bottom (tapering) by Action of Gravity Field；Its residual air powder is continued up, due to filtering
The filtration of device, powder can not pass through, and be attached to filter appearance；Gas then continues to move ahead by filter, until outlet
Discharge.
Brief description of the drawings
Fig. 1 show the structural representation of explosion-proof dust arrester of the present utility model.
Embodiment
As shown in figure 1, explosion-proof dust arrester of the present utility model include offer the thin mouth of strip grid type dust shield 1,
The dedusting tank 3 that is connected by cleaning shaft with grid type dust shield, the filter 4 being arranged in dedusting tank, installed in dedusting tank
The detonating fusee 5 covered, the air-introduced machine 7 for being arranged on the ash-removing valve 6 of dedusting pot bottom and dedusting tank being connected by pipeline, its
In, flame proof valve 2 is provided with cleaning shaft.
Grid type dust shield is stainless steel flat casing, and dust suction face arc opens the thin mouth of strip to produce blast, increase is inhaled
Power.All turnings of cleaning shaft are designed as streamlined, reduction resistance.Flame proof valve is convertible flame proof valve.In dust arrester
Under normal operating conditions, flame proof flap is kept it turned under negative-pressure air-flow effect.Under static state, flap is in its Gravitative Loads
It is lower to close, and be close on the sealing surface of flame proof valve inlet side.In normal operation, if occur in flame proof valve front end detonation or
Blast, pipeline forefront pressure increase, flow reversal, flame proof valve is closed.Flap is close to entrance side under blast pressure effect
Sealing surface on, and self-locking mechanism automatic locking prevents explosive flame and pressure-wave propagation.Dedusting tank is that stainless steel is vertical
Closed tank body, inner fixed filter is that airborne dust (gas powder) provides separated space, and collect dust.Filter is filtered using non-woven fabrics
Cylindricality (taper) filter of material, the top in dedusting tank, for Chalk-dust filtering particle, gas passes through unaffected.Let out
Booster is covered installed in dedusting tank, both ends open, upper end connection air, and inside lower end connection dedusting tank, venting of dust explosion piece is provided with pipe.
When dedusting tank occurs surprisingly to fire, pressure inside the tank increased dramatically, and venting of dust explosion piece ruptures and to aerial pressure of releasing, and protection dedusting tank makes
With safety.
Workflow is as follows：Production operation airborne dust absorption affinity effect under, from grid type dust shield suction, through pipeline, every
Quick-fried valve enters in dedusting tank；Wherein, dust granules are separated and are collected in dedusting tank, separate under gravity and filter effect
Gas moves ahead upwards through filter afterwards, until outlet discharge.With mallet rapping dedusting tank wall, make filter and top tank structure dust
Bottom is fallen into, then opens ash-removing valve and is collected, dedusting work is completed.
Compared with conventional cleaner device, deduster of the present utility model has the advantage that：
1) flexibility：Dust shield can use combination by dust suction face, meet different work application requirements；Air-introduced machine is change
Frequency explosion-proof type air-introduced machine, wind-force size is easy to adjust；
2) reliability：Dust separation is carried out in dedusting tank, is collected, good airproof performance, reliability is high；
3) security：The present apparatus has flame proof valve, detonating fusee and earthing or grounding means, and security is higher.
