Abstract
The utility model discloses a quick opening-closing structure of a flue in a dust catcher, which can quickly open and close the flue. The structure comprises a flue, wherein a step-shaped pore plate matched with the flue is fixed inside the flue; each step of the step-shaped pore plate is provided with an air vent; the step-shaped pore plate is provided with at least two steps; a lifting valve is arranged on the outer side of the flue; a valve rod of the lifting valve is inserted into the flue; and the lower end of the valve rod is connected to a valve cover matched with the air vent. The quick opening-closing structure of a flue in a dust catcher has the advantages that the use cost is low, the flue can be quickly opened and closed, the structure is simple, the operation is convenient, and the use is safe and reliable.
Description
Technical field
The utility model relates to a kind of deduster, relates in particular to the quick opening and closing mechanism of flue in a kind of deduster.
Background technology
On the flue of deduster, the double-deck baffle door that opens or closes main employing electric operator driving of control flue is realized the flue zero leakage at present.In order to realize flue zero leakage, needing provide the sealing gas that is higher than flue gas pressures in the flue by seal fan, realizes that gas cuts off flue gas from baffle door is inner toward the flue internal and outernal leakage, and realization is not revealed to the flue rear end.Owing to use equipment such as seal fan, cause use cost higher, and the time of actuator opening and closing flue is longer, can not realize opening and closing fast flue.
The utility model content
Technical problem to be solved in the utility model is: the quick opening and closing mechanism that flue in a kind of deduster that can open and close flue fast is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the quick opening and closing mechanism of flue in the deduster, comprise: flue, in described flue, be set with the notch cuttype orifice plate that cooperatively interacts with it, each ladder of notch cuttype orifice plate is provided with passage, has two ladders on the notch cuttype orifice plate at least, in the arranged outside of flue lift valve is arranged, the valve rod of lift valve extend into flue inside, is connected with the valve gap that cooperatively interacts with passage in the lower end of valve rod.
The utility model has the advantages that: the quick opening and closing mechanism of flue in the deduster of said structure, use cost is low, can open and close flue fast, and is simple in structure, easy to operate, safe in utilization, reliable.
Description of drawings
Fig. 1 is the structural representation of the quick opening and closing mechanism of flue in the utility model deduster.
Among the figure: 1, flue, 2, the notch cuttype orifice plate, 3, passage, 4, lift valve, 5, valve rod, 6, valve gap.
The specific embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the quick opening and closing mechanism of flue in the deduster, comprise: flue 1, in described flue 1, be set with the notch cuttype orifice plate 2 that cooperatively interacts with it, each ladder of notch cuttype orifice plate 2 is provided with passage 3, have two ladders on the notch cuttype orifice plate 2 at least, ladder number on the notch cuttype orifice plate 2 can be provided with arbitrarily according to actual needs, arranged outside at flue 1 has lift valve 4, the valve rod 5 of lift valve 4 extend into flue 1 inside, is connected with the valve gap 6 that cooperatively interacts with passage 3 in the lower end of valve rod 5.
When needs connection flue gas is opened flue, open lift valve 4, the valve rod 5 of lift valve 4 drives valve gaps 6 and breaks away from mutually with notch cuttype hole 2, is communicated with flue gas; When needs cut-out flue gas is closed flue, close lift valve 4, valve gap 6 contacts sealing with notch cuttype hole 2, cuts off to intercept flue gas.
Claims (1)
1. the quick opening and closing mechanism of flue in the deduster, comprise: flue (1), it is characterized in that: in described flue (1), be set with the notch cuttype orifice plate (2) that cooperatively interacts with it, each ladder of notch cuttype orifice plate (2) is provided with passage (3), have two ladders on the notch cuttype orifice plate (2) at least, arranged outside at flue (1) has lift valve (4), the valve rod (5) of lift valve (4) extend into flue (1) inside, is connected with the valve gap (6) that cooperatively interacts with passage (3) in the lower end of valve rod (5).
