Description
Technical field
It the utility model is related to fire inspection fans entrance filter screen fittable slackening device.
Background technology
At present, power plant's fire inspection blower fan structure form is cantilevered centrifugal blower, and blower foundation is Hard link, is subtracted without elasticity
Shake device.Fan operation mode is the using and the reserved, and fan outlet realizes the switching of blower fan by reversible deflector.Fans entrance is equipped with
Air filtration filter screen, ensure the air cleaning degree of suction.Current fire inspection fans entrance filter screen and shield gross weight are about
26Kg, diameter 720mm, shell length 700mm, it is connected by flange with fans entrance end cap.During fan operation, air
In the dust adsorption that filters out in filter screen, with the extension of run time, the dust of absorption is more and more, and filter screen weight is gradual
Increase, reaches more than 30Kg, leeward machine filter network capacity affected by gravity easily show it is now vertical show, make the end of blower fan
Lid is deformed.The problem of vibration is higher is often occurring during operation for fire inspection blower fan existing at present, due to blower fan
Casing and blower foundation platen employ Hard link, and platen uses the thick steel plates of 5mm, the deformation of fan casing and then
The deformation of blower foundation platen is caused, fan vibration value is caused and increases.And when fan vibration is high, if by fans entrance
Filter screen is raised, and measurement fan vibration value then significantly decreases, and existing fire examines fans entrance filter screen usually not at present
Support meanss, when needing to remove filter screen, it is necessary to there are two people to hold filter screen, a people removes flange bolt, time-consuming expense be present
The problem of power.Therefore a kind of support meanss that can be supported filter screen and filter screen can be raised are needed.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide fire inspection fans entrance filter screen fittable slackening device, this reality
With new in disassembly and installation filter screen, there is no support meanss before solving, it is necessary to there are two people to hold filter screen, a people tears open
Except flange bolt, the problem of wasting time and energy, the utility model does not need manpower to lift filter screen, makes installation and dismounting filter screen more square
Just.
Technical scheme is used by the utility model solves above-mentioned technical problem：Fire inspection fans entrance filter screen installation support
Device, including:Base, support frame, screw thread elevating lever, nut and arc, it is characterised in that：The base is arranged on the branch
The lower end of support, it is mutually permanently connected between the base and support frame as described above, the screw thread elevating lever is arranged on the base
Upper end, between the screw thread elevating lever and base mutually be threadedly coupled each other, the nut is set on the screw thread elevating lever,
By adjusting nut, screw thread elevating lever can be with oscilaltion, and the arc is arranged on the upper end of the screw thread elevating lever, arc
Plate is mutually permanently connected with the screw thread elevating lever.
Further, it is provided with rubber blanket on the arc.
Further, the screw thread elevating lever is shaped as T-shaped.
Further, the material of the nut is copper.
The utility model has the advantage of：The utility model uses T-shaped screw thread elevating lever, by adjusting copper nut, screw thread
Elevating lever can be adjusted up and down, the arc contacted with filter screen shield, equipped with rubber blanket, serve the effect of buffering.This practicality
New the reason for filter screen will not be because of gravity, is sagging after mounting, causes blower foundation platen to deform, causes asking for fan vibration
Topic, can make fan operation more steady.The utility model is in disassembly and installation filter screen, without support dress before solving
Put, it is necessary to there are two people to hold filter screen, a people removes flange bolt, and the problem of wasting time and energy, the utility model is not required to very important person
Power lifts filter screen, makes installation and dismounting filter screen more convenient.
