A kind of economizer anti-leak warning device
Technical field
The present invention relates to economizer early warning technology field, specially a kind of economizer anti-leak warning device.
Background technique
Economizer is a kind of a kind of device for being installed on boiler back end ductwork lower part and being used to recycle discharged fume waste heat, tool
The features such as having reduces flue gas exhaust gas temperature, saves the energy, improves the thermal efficiency.Economizer is divided into steel pipe type and cast iron by its structure
Formula, wherein steel pipe type economizer is widely used in high parameter, heavy duty boiler.Steel pipe type economizer be by it is horizontally disposed simultaneously
Join connector bend (being commonly called as coiled pipe) composition.Due to containing a large amount of ash particles in high-temperature flue gas, in boiler in use, a large amount of ashes
Divide particle to pass through steel pipe type economizer, can rub with its inner wall, steel pipe type economizer is caused to wear and then leads to economizer
Leakage;According to data statistics, economizer occurs to be normally at the snakelike tube bank elbow of high temperature section at wear and leakage.Therefore, for
The leakage of economizer carries out prevention alarm, be very it is necessary to.
The leakage alarm of previous economizer is alarmed using observation.Observation is that flue-gas temperature can be bright after leaking
It is aobvious reduce or deduster coherent detection data are abnormal, economizer leakage is judged with this, but there are biggish for this method
Contingency, and could only be arrived by other Data Detections when leaking more serious.
Summary of the invention
In order to solve the above-mentioned technical problem, the invention proposes a kind of economizer anti-leak warning devices.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of economizer anti-leak warning device, including removably assemble and with economizer tube fit with shape
At the first shell of sealing space, the second shell being connected with first shell, slides in second shell and there is reset function
Can push rod and rack gear, the plate that hits for hitting, being symmetrically distributed in percussion hammer two sides that is hinged on second shell inner sidewall, the push rod with
Rack gear connection, the rack gear are engaged with gear;
The gear side wall, which is equipped with, to be slidably connected so that percussion hammer reciprocally swinging taps the convex block for hitting plate with percussion hammer end.
Further, the first shell is spelled by the No.1 U-shaped shell positioned inside, No. two U-shaped shells positioned at outside
It fills.
Further, the No.1 U-shaped shell, No. two U-shaped shells assembling part any one be equipped with Anti-dislocation step,
Another is equipped with the Anti-dislocation card slot being adapted to Anti-dislocation step.
Further, the both ends exit of the first shell is equipped with the sealing ring fitted closely with economizer pipeline.
Further, the rack gear end is connected with reset spring.
Further, the slideway for push rod guiding is equipped in the second shell, for the sliding slot of rack gear guiding.
The beneficial effects of the present invention are:
Compared with the existing technology, it is empty to will form a sealing by first shell after cooperating with economizer elbow by the present invention
Between, pass through the air pressure generated when leakage and drive rack gear movement, so that making gear that percussion hammer reciprocally swinging be driven to hit plate generates report
Alert sound, and then reach warning function.The present invention has high efficiency, real-time, and structure is simple, stability, is easily installed and ties up
Shield maintenance.

Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
It closes attached drawing and the present invention is further described in embodiment.
As shown in Figures 1 to 5, a kind of economizer anti-leak warning device, including shape are adapted and can pass through spiral shell
Bolt nut is mutually assembled into the No.1 U-shaped shell 1a of first shell 1, No. two U-shaped shell 1b, the spelling of the No.1 U-shaped shell 1a
Anti-dislocation step 10 is equipped at dress, the assembling part of No. two U-shaped shells 1b is equipped with the Anti-dislocation being adapted to Anti-dislocation step 10
Card slot 11, the both ends exit of the first shell 1 are equipped with the sealing ring 8 fitted closely with economizer elbow lateral wall.Institute
State and be provided with coupled logical second shell 2 on the right side of No.1 U-shaped shell 1a, 2 inside left of second shell be equipped with
It is sliding inside the slideway 2a, the slideway 2a that No.1 U-shaped shell 1a is connected that push rod 3 is housed;2 inner right side of second shell
Rear wall, which is equipped in the sliding slot 2b, the sliding slot 2b being distributed in the horizontal direction, to be slided equipped with rack gear 4, and the rack gear 4 and push rod 3 are logical
Screw is crossed to link together;It is connected with reset spring 9 between right side wall inside 4 right part of rack gear and second shell 2, when
Push rod 3 is synchronized together with rack gear 4 understands compression reseting spring 9 when turning right mobile, turn right to move together with rack gear 4 when push rod 3 and complete
Afterwards, reset spring 9 restores to the original state, and push rod 3 is pushed together with rack gear 4 toward left side, its reset is made.
The lower section of the rack gear 4 is engaged with gear 5, and the gear 5 is mounted on the rear side inside second shell 2 by bearing
On wall;The front of the gear 5 is equipped with percussion hammer 6, and the percussion hammer 6 is hinged on the front side wall inside second shell 2, the percussion hammer
6 left and right sides, which is symmetrically distributed with, hits plate 7, and the plate 7 that hits is iron sheet plate;The upper end of the percussion hammer 6 is equipped with sliding slot 6a, institute
It states the cylindrical bump 51 being fixedly connected in insertion sliding slot 6a on the front end face of gear 5 and gear is worked as by the setting of convex block 51
5 by rack gear 4 when driving and rotating, and convex block 51 can be rotated with gear 5, by the cooperation of convex block 51 and sliding slot 6a, and then be made
Percussion hammer 6 is obtained around its hinge joint or so reciprocally swinging, so that hitting plate 7 at left and right sides of 6 reciprocating percus-sion of percussion hammer.
Use process:
As shown in fig. 6, No.1 U-shaped shell 1a and No. two U-shaped shell 1b are separated position, second shell 2 and one when initial
Number U-shaped shell 1a is connected.
When installation, No.1 U-shaped shell 1a, No. two U-shaped shell 1b correspondences are stuck on economizer pipeline elbow in advance first, are connect
No.1 U-shaped shell 1a, No. two U-shaped shell 1b are fitted together by bolt and nut, and pass through sealing ring 8, Anti-dislocation platform
No.1 U-shaped shell 1a, No. two U-shaped shell the 1b first shell 1 assembled are pacified in the setting of rank 10 and Anti-dislocation card slot 11
Behind economizer elbow, a sealing space will form.
In use, when economizer pipeline elbow leaks, the pressure in first shell 1 increases, pressure-ram 3 and
Rack gear 4 is turned right movement, and band moving gear 4 rotates clockwise in 4 moving process of rack gear, push rod convex block 51, so that percussion hammer 6 is around it
Hinge joint or so reciprocally swinging so that the head reciprocating percus-sion of percussion hammer 6 hits plate 7, and then makes a sound, to reach prevention alarm
Effect.
