Abstract
The utility model relates to a conical plug-in underneath bag-changing device, which is convenient to change filter bags for bag type dust collectors. A circular venturi supporting platform with a frustum tail is fixed on a blossom hole plate. The lower part is provided with two sections of cones which inverses to different cones. Conical surface at feet is provided with a half concave circular ring. A screen frame with a conical bowl can be fixed on the half concave circular ring by a holding screw. The screen frame is connected with a frame flat steel by a screw bolt. A frame is welded on the frame flat steel. The filter bags can be ligated on the screen frame. When changing the bags, the utility model only needs to open access doors which are arranged at the middle lower parts of the dust collectors for replacing filter clothes conveniently. The utility model has the advantages good tightness, good neutrality, good wholesomeness, good safety and low investment.
Description
The utility model is that a kind of sack cleaner of being convenient to is changed under the tapered plugging formula of filter bag and changed bagging apparatus.
Existing GB T540-8 " MC24-120-II type " pulse bag type dust collector, what change the bag technique employing is to change bagging apparatus on the draw and insert-type, this fixed form sealing, better to neutrality, and the people does not enter the deduster housing, just can overhaul and change bag, improve workman's work situation.But consider that from security standpoint its safe coefficient is not high, people must climb to the high deduster top of 3.7M and go up and could operate when changing bag, and person is changed bag problem of difficulty, also fundamentally is not resolved.Simultaneously, on change the bagging apparatus requirement and the factory building clear height be installed more than 5.5M, also increase added burden to customer investment.
The purpose of this utility model will solve just and change the difficult problem of bag, designs a kind of new device and is used for fixing filter bag, satisfies sealing simultaneously, to neutrality, wholesomeness, security, operates simply, easily and fast, can also save equipment investment to greatest extent.
Structure of the present utility model is referring to accompanying drawing.
Among the figure, (1)---the Venturi tube of band frustum tail, (2)---the strainer frame of band taper the rim of a bowl, (3)---holding screw, (4)---filter bag, (5)---flower orifice plate.
(2-1)---the frame band steel, (2-2)---framework, (2-3)---bolt.
The top of the Venturi tube of band frustum tail is horn-like induction tunnel, than the middle part is an annular brace platform, the bottom is that two sections circular cones are swung to different hollow cones, the taper seat of its foot cone has a semicircular ring that falls in, these variform structural group of each become a hollow metal entity, can overlap the strainer frame of tape splicing taper the rim of a bowl, the strainer frame is fixed on the taper seat of Venturi tube lower end by holding screw, the strainer frame also has the frame band steel by several bolting of circumferential arrangement simultaneously, be welded with framework on the frame band steel, framework is outer can the suit filter bag.Consider the convenience of maintenance and dismounting, and the distortion that easily produces of weldment, strainer frame and frame band steel are made two separate piece, and the semicircular ring that falls in is arranged so that prick and tie filter bag also keeping somewhere one week of outer surface of strainer frame, prevent to come off.
When using the utility model, Venturi tube is placed on the upper end of flower orifice plate in the deduster, and is fixed, its strainer frame just can put in the lower end that is fixed on Venturi tube in it than the access door (setting up mechanism) at middle part by being arranged on the deduster shell.As long as no matter maintenance or open access door when changing bag like this, the people need not climb, and also need not enter the deduster housing, stretches out one's hand and unclamps holding screw, pats a lower filter belt frame, can pull down and take out outside the deduster, it is simple, convenient to change filter bag.
Claims (2)
1, a kind of deduster of being convenient to is changed under the tapered plugging formula of filter bag and is changed bagging apparatus, it is characterized in that the Venturi tube with the frustum tail is a variform hollow metal body of each, its top is horn-like, the tool middle part is an annular brace platform, the bottom is that two sections circular cones are swung to different cones, the taper seat of foot cone has a semicircular ring that falls in, and this taper seat is used for overlapping the strainer frame of tape splicing taper the rim of a bowl, is fixed by holding screw.
2, apparatus for changing under the tapered plugging formula according to claim 1, it is characterized in that being provided with the semicircular ring that a spill is entered with the strainer frame outer surface of taper the rim of a bowl, prick the knot filter bag on the semicircular ring, the bolt that circumferentially is provided with by the strainer frame is used for fixing the frame band steel, is welded with framework on the frame band steel.
