Abstract
The invention discloses a valve-lift installing structure in the bag-type duster, which has simple structure and is practical and reliable. The hinge-type valve installing structure in the bag-type duster comprises a lift valve and a pore plate, wherein the lift valve and the pore plate are arranged at the upper end of a box body, ventilation holes are arranged on the pore plate, the upper end of the box body is divided into an air-purifying chamber and a ventilation channel by the pore plate, the pore plate is obliquely arranged on the box body between the air-purifying chamber and the ventilation channel, a retainer ring is arranged on the pore plate of the outer side of the ventilation holes, and a valve rod of the lift valve is articulated with a valve cover which is mutually matched with the retainer ring by a hinge shaft. The hinge-type valve installing structure in the bag-type duster has simple structure and is practical and reliable, the valve cover and the pore plate are obliquely arranged, air flows can smoothly pass through the pore plate, eddy flows are not easy to generate at the end of the air-purifying chamber in order to reduce pressure loss to the maximum extent and improve ventilation effect. When the lift valve has faults, the valve rod drops to automatically open the valve cover and does not influence the normal operation of a duster and a boiler.
Description
Technical field
The present invention relates to a kind of sack cleaner, relate in particular to the mounting structure of hinge type valve in a kind of sack cleaner.
Background technology
The mounting structure of hinge type valve in the existing sack cleaner, comprise: the lift valve and the orifice plate that are arranged on the casing upper end, orifice plate is provided with passage, the valve rod of lift valve is provided with the valve gap that cooperatively interacts with passage, orifice plate is separated into air-purifying chamber and two parts of airway with the upper end of casing, described orifice plate is horizontally set on the casing between air-purifying chamber and the airway, and upper end and orifice plate that described lift valve is horizontally set on casing cooperatively interact.The mounting structure of above-mentioned poppet is contained in when using in the sack cleaner, open lift valve, valve rod drives the valve gap withdrawal, passage on valve gap and the orifice plate is separated from each other, air-flow enters in the ash bucket that is arranged on the casing lower end from air inlet pipe, filter bag through the casing upper end enters air-purifying chamber, enters in the airway from passage then and discharges.Because valve gap and orifice plate are arranged horizontally, air-flow turbulent flow occurs in the end of air-purifying chamber easily, and the build-up of pressure loss is bigger than normal, influences ventilation effect, and when lift valve broke down, valve rod fell gas channel is closed, and influences the normal operation of deduster, boiler.
Summary of the invention
Technical problem to be solved by this invention is: the mounting structure that poppet in a kind of simple in structure, practical and reliable sack cleaner is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the mounting structure of hinge type valve in the sack cleaner, comprise: the lift valve and the orifice plate that are arranged on the casing upper end, orifice plate is provided with passage, orifice plate is separated into air-purifying chamber and two parts of airway with the upper end of casing, described orifice plate is obliquely installed on the casing between air-purifying chamber and the airway, the orifice plate in the described passage outside is provided with back-up ring, by the hinge hinge valve gap that cooperatively interacts with back-up ring is arranged on the valve rod of described lift valve.
Advantage of the present invention is: the mounting structure of hinge type valve in the sack cleaner of said structure, simple in structure, practical reliable, valve gap and orifice plate are in tilted layout, air-flow can pass through orifice plate smoothly, is not easy turbulent flow to occur in the end of air-purifying chamber, at utmost reduces the pressure loss, improve ventilation effect, when lift valve broke down, valve rod fell to opening valve gap automatically, does not influence the normal operation of deduster, boiler.
Description of drawings
Fig. 1 is sack cleaner valve gap that the mounting structure of hinge type valve in the sack cleaner of the present invention the is housed structural representation when opening.
Fig. 2 is sack cleaner valve gap that the mounting structure of hinge type valve in the sack cleaner of the present invention the is housed structural representation when closing.
Among the figure: 1, casing, 2, lift valve, 3, orifice plate, 4, passage, 5, air-purifying chamber, 6, airway, 7, back-up ring, 8, valve rod, 9, hinge, 10, valve gap, 11, air inlet pipe, 12, ash bucket, 13, filter bag.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the mounting structure of hinge type valve in the sack cleaner, comprise: the lift valve 2 and the orifice plate 3 that are arranged on casing 1 upper end, orifice plate 3 is provided with passage 4, orifice plate 3 is separated into air-purifying chamber 5 and 6 two parts of airway with the upper end of casing 1, described orifice plate 3 is obliquely installed on the casing 1 between air-purifying chamber 5 and the airway 6, the orifice plate 3 in described passage 4 outsides is provided with back-up ring 7, by hinge 9 hinges the valve gap 10 that cooperatively interacts with back-up ring 7 is arranged on the valve rod 8 of described lift valve 2.
As shown in Figure 1, the mounting structure of above-mentioned poppet is contained in when using in the sack cleaner, open lift valve 2, valve rod 8 stretches out by hinge 9 and drives valve gap 10, valve gap 10 and back-up ring 7 are separated from each other, air-flow enters from air inlet pipe 11 in the ash bucket 12 that is arranged on casing 1 lower end, and the filter bag 13 of process casing 1 upper end enters air-purifying chamber 5, enters in the airway 6 from passage 4 then and discharges.Because valve gap 10 is in tilted layout with orifice plate 3, air-flow can pass through orifice plate 3 smoothly, be not easy turbulent flow to occur in the end of air-purifying chamber 5, at utmost reduce the pressure loss, improve ventilation effect, when lift valve 2 broke down, valve rod 8 fell to opening valve gap 10 automatically, does not influence the normal operation of deduster, boiler.
As shown in Figure 2, when needs were closed valve gap 10, valve rod 8 withdrawals drove valve gap 10 by hinge 9, valve gap 10 is in contact with one another with back-up ring 7 cooperates.
