Mobile dust arrester
Technical field
The utility model relates to a kind of ventilating dust-arrester, is specifically related to a kind of dust arrester of the airborne dust point along straight reciprocating motion.
Background technology
The raw material system that mainly comes from iron and steel enterprise along the dirt source of straight reciprocating motion mainly contains following several at present to its administration way:
1, each ore deposit groove trough rim is provided with a dust shield respectively, and an electrically operated valve is set behind each dust shield, and electrically operated valve and groove loading and unloading material dolly are chain, and when dump car during in certain groove discharging, the electrically operated valve of this groove is opened automatically, takes the dust-contained airflow of this groove away.
2, the bag-type dusting unit is installed and controls airborne dust on dump car.
3, adopt the big enclosed hood of rigidity to seal in the total travel scope of traveling producing dirt equipment airborne dust point, a large amount of exhausting make to form negative pressure in the cover, prevent that dust from escaping.
4, adopt CN 2201993Y " portable dedusting ventilating opening device ", ore deposit groove feed opening seals with belt.
The problem that these administration ways exist is:
First kind of mode is provided with suspended hood and electrically operated valve respectively at each ore deposit groove, and the unlatching and the dump car of valve are chain.The dump car operation is frequent, valve opening and closing is also frequent, because sintering deposit dust hardness height, dust granules particle diameter and proportion are all bigger, and dust has certain caking property, frequent keying often causes valve to break down, can not normally enable, the valve that should close can not be closed fully, the valve that should open can not complete opening, makes the air quantity that should concentrate on controlled hopper be assigned to a plurality of uncontrolled hoppers, and the air quantity of controlled hopper reduces relatively, cause the wind speed decreased in the airduct, collection ash in the airduct, blocking pipe, whole system is day by day paralysed.
The second way, dust removal machine are assembled on the frame of dump car, have increased the height and the weight of car body, and floor space is big, increase equipment investment.The old factory building of some enterprises is difficult to adopt; Dedusting unit cleaned air passes directly is discharged in the workshop, and its concentration of emission far surpasses national workspace sanitary standard.
The third mode, equipment are in the big enclosed hood of rigidity, and component wear is big, the fault rate height, and the space is little in the cover, is not easy to regular maintenance and maintenance.
The 4th kind of mode, dedusting dolly are difficult to and produce the operation of dirt device synchronization, the easy sideslip of belt sealing device belt, and normal appearance overlaps, pleating phenomenon causes belt tearing to break, and produces dirt equipment at last and slides down, and influence is produced.
Summary of the invention
In order to overcome the deficiency that existing various mobile dirt source administration way exists, the utility model improves on the basis of CN2201993Y " portable dedusting ventilating opening device " technical scheme, design a kind of dedusting dolly and not limited by the walking of dump car, the sealing belt is difficult for mobile dust arrester pleating, sideslip.
The technical solution that the utility model adopts is: this device comprises that the dirt source captures and dust source enclosure two parts, the dirt source captures and is made of dedusting dolly and dedust air duct, dedusting dolly and dedust air duct adopt and flexibly connect, flexible steel in flat section tubing is enclosed within the outside of dedust air duct horizontal direction, stirs the dedusting dolly with a pair of shift pole and moves.Dust source enclosure has belt seal and clean-out hatch seal, on the sealing belt at belt seal two ends strain component is set, and an end of sealing belt adopts wire tensioner to fix, and the other end adopts spring to fix; The clean-out hatch seal is at each Hatch Opening the cleaning discharge port to be set, and at the discharge port seal of packing into, seal adopts gravity turnover panel structure.
The beneficial effects of the utility model are: the dolly of this device design and the connected mode of airduct, can be when producing dirt equipment orbit appearance distortion, and the dedusting dolly still can synchronous operation.The tension on belt fixed form of this device design, solved the original problem that is difficult for adjusting with bolting belt length, make that belt tension can be regulated, belt length can be regulated, avoid belt overlapping, pleating, deviation phenomenon to occur, carry out smoothly to guarantee to produce.Originally after the Hatch Opening sealing, a material mouthful cleaning is difficult to solve, the clean-out hatch sealing device of the utility model design designs according to gravity turnover panel principle, when clear material, blanking or dust are swept to the limit, hole, open the gravity turnover panel by gravity, automatically fall into blanking or dust in the storehouse, be easy-unloading, play sealing function again, guaranteed dust removing effects.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1 and Figure 2, this moves dust arrester and comprises that the dirt source captures and the dirt source seals two parts.
The dirt source captures and is made of dedusting dolly 1 and dedust air duct 4, and dedusting dolly 1 and dedust air duct 4 adopt and flexibly connect, and flexible steel in flat section tubing 7 is enclosed within the outside of dedust air duct 4 horizontal directions, stirs dedusting dolly 1 with a pair of shift pole and moves.
The dirt source is sealed with belt seal 2 and clean-out hatch seal 3, strain component 5,6 is set on the sealing belt at belt seal 2 two ends, one end of sealing belt 11 adopts wire tensioner 9 fixing, the other end adopts spring 14 fixing, as Fig. 4, shown in Figure 5, one side of wire tensioner 9 is connected with bail seat 8, and another side is connected with clamping plate 10, and clamping plate 10 compress sealing belt 11; Spring 14 is fixed on the base 13, by the clamping plate 10 tension sealing belts 11 that compress sealing belt 11.
Clean-out hatch seal 3 is at each Hatch Opening 1~2 cleaning discharge port to be set, and at the discharge port seal 3 of packing into, seal 3 adopts gravity turnover panel structures, as shown in Figure 6.
