Abstract
The utility model relates to a dust removing device, in particular to a venturi tube with an adjustable throat, which adopts the technical proposal that a throat plate (4), a reducing plate (5) and an adjusting rod (6) are arranged on the inner wall of a throat (2), the throat plate is hinged with the reducing plate, the reducing plate is connected with the inner wall of the throat, and the adjusting rod is penetrated by the wall of the throat and is connected with the throat plate. The adjusting rod is driven by external force to move in the direction perpendicular to the throat wall, so that the flow area of the throat is changed, and the throat plate has any length, so that the flow rate meeting the requirement can be ensured within a certain length, and the purifying and dedusting effects are improved.
Description
The utility model relates to cleaner, particularly a kind of Venturi tube of adjustable aditus laryngis.
At present, Venturi tube is widely used in the cleaner, general Venturi tube has Venturi tube top, aditus laryngis, the Venturi tube bottom is formed, aditus laryngis is between Venturi tube top and bottom, for improving efficiency of dust collection, requiring the aditus laryngis of Venturi tube to change with flue gas flow enlarges or dwindles, for regulating the size of Venturi tube aditus laryngis, someone is provided with an oval core body in aditus laryngis, its central shaft is connected with hydraulic mechanism, drive oval core body by hydraulic mechanism and rotate, the distance of oval core body upper and lower and aditus laryngis inwall is changed, reach and regulate the aditus laryngis area of passage, the purpose that adapts to gas flow rate.But this adjustable aditus structure can only make oval core body end reach the flow velocity requirement, can not all reach this flow velocity in an effective length, thereby the water of ejection is atomized fully, and soot dust granule and droplet are fully collided and coagulation, and efficiency of dust collection is low.
The utility model purpose provides a kind of Venturi tube of adjustable aditus laryngis, regulates the aditus laryngis area of passage, all reaches satisfactory flow velocity in certain effective length, solves the problems referred to above that prior art exists.
Technical solutions of the utility model are: aditus laryngis plate, reducing plate and adjusting rod are set on the inwall of aditus laryngis, and aditus laryngis plate and reducing plate are hinged, and the reducing plate is connected with the aditus laryngis inwall, and adjusting rod is penetrated by the aditus laryngis wall, are connected with the aditus laryngis plate.
Adopt the utility model,, drive the aditus laryngis plate and move in direction perpendicular to the aditus laryngis wall by external force effect adjusting rod, change the area of passage of aditus laryngis, because the aditus laryngis plate has length arbitrarily, can guarantee to reach in certain length satisfactory flow velocity, improve the purifying and dedusting effect.
The utlity model has characteristics such as area of passage rational in infrastructure, as can to regulate aditus laryngis arbitrarily, raising purifying and dedusting effect.
Accompanying drawing 1 is the utility model example structure schematic diagram.
Accompanying drawing 2 is the utility model embodiment 1 structural representation.
Accompanying drawing 3 is the utility model embodiment 2 structural representations.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
Embodiment 1
In embodiment 1, the utility model is by Venturi tube top (1), aditus laryngis (2), Venturi tube bottom (3) is formed, aditus laryngis is between Venturi tube top and bottom, aditus laryngis plate (4) is set on the inwall of aditus laryngis (2), reducing plate (5) and adjusting rod (6), aditus laryngis plate (4) is hinged with reducing plate (5), reducing plate (5) is slidingly connected with aditus laryngis (2) inwall, the contact site of reducing plate and aditus laryngis inwall is provided with movable pulley (7), the aditus laryngis inwall is provided with sliding rail (8), movable pulley slides in sliding rail, adjusting rod (6) is penetrated by aditus laryngis (2) wall, is connected with aditus laryngis plate (4).When needs change the area of passage of aditus laryngis, external force drives adjusting rod, make and be attached thereto the aditus laryngis plate that connects and moving perpendicular to aditus laryngis wall direction, the hinged reducing plate of drive and aditus laryngis plate moves, movable pulley on the reducing plate slides in orbit, to adapt to moving of aditus laryngis plate, the aditus laryngis plate can move to the position of any needs, finish the task of changing the aditus laryngis area of passage, the length of aditus laryngis plate is arbitrarily, can guarantee in certain length, to reach satisfactory flow velocity, improve the purifying and dedusting effect.
In embodiment 2, reducing plate (5) is telescopic, is made of fixed head (9) and movable plate (10), and movable plate is inserted in the fixed head, slides in fixed head.When needs change the area of passage of aditus laryngis, external force drives adjusting rod, make and be attached thereto the aditus laryngis plate that connects and moving perpendicular to aditus laryngis wall direction, the hinged reducing plate of drive and aditus laryngis plate moves, the movable plate of reducing plate slides in fixed head, changes the length of reducing plate, to adapt to moving of aditus laryngis plate, the aditus laryngis plate can move to the position of any needs, finishes the task of changing the aditus laryngis area of passage.
Claims (3)
1, a kind of Venturi tube with adjustable aditus laryngis of Venturi tube top (1), aditus laryngis (2), Venturi tube bottom (3), aditus laryngis is between Venturi tube top and bottom, it is characterized in that on the inwall of aditus laryngis (2), being provided with aditus laryngis plate (4), reducing plate (5) and adjusting rod (6), aditus laryngis plate (4) is hinged with reducing plate (5), reducing plate (5) is connected with aditus laryngis (2) inwall, adjusting rod (6) is penetrated by aditus laryngis (2) wall, is connected with aditus laryngis plate (4).
2, according to the Venturi tube of the described adjustable aditus laryngis of claim 1, it is characterized in that reducing plate (5) and aditus laryngis (2) inwall are slidingly connected, the contact site of reducing plate and aditus laryngis inwall is provided with movable pulley (7), and the aditus laryngis inwall is provided with sliding rail (8), and movable pulley slides in sliding rail.
