Abstract
The invention relates to an alarm device, in particular to an automatic monitoring alarm device for cooling water cut-off of a bearing of a dust removing fan. According to the technical scheme, the automatic monitoring alarm device comprises a supporting frame, a balance beam, a hanging rope, a counterweight, a water collecting bucket, a stroke switch, an electric bell and a trigger rod. The upper end of the supporting frame is rotationally connected with the middle portion of the balance beam. The counterweight and the water collecting bucket are installed at the two ends of the balance beam correspondingly through the hanging rope. The stroke switch is installed on the side face of the supporting frame. The electric bell is connected with the stroke switch. The trigger rod is installed on the side, close to the counterweight, of the balance beam. The end of the trigger rod faces the stroke switch. Meshes are formed in the bottom of the water collecting bucket. Cooling water in a cooling water recycling pipe flows into the water collecting bucket. The water collecting bucket is installed above a cooling water tank. By the adoption of the automatic monitoring alarm device, a failure alarm signal can be given out automatically when water of a circulating water pump is cut off, and full-automatic monitoring is achieved.
Description
Technical field
The present invention relates to a kind of alarm, be specifically related to a kind of dedusting fan bearing cooling water and cut off the water supply
Automatically-monitored alarm.
Background technology
Dedusting fan is the vitals of electrostatic precipitation, is power resources.Blower fan is dependent on input
Mechanical energy, improve gas pressure and supply gas side by side the machinery of body, it is a kind of driven fluid machine
Tool.Main heating position when operating for it, such as the friction between axle and bearing, utilization follows
Heating position is cooled down by ring water, thus ensures that dedusting fan runs well.
Dedusting fan recirculating water pump breaks down, and causes dedusting fan bearing cooling water to be cut off the water supply,
Thus bearing produces high temperature failure blower fan bearing shell, affect dedusting fan and run well.Along with dedusting
The continuity and aging of blower fan recirculating water pump operating, owing to producing in the pump housing during operating
Incrustation scale, often can cause the damage of water circulating pump blade, also the abrasion of motor etc. are many former
Because affecting the normal operation of water circulating pump, time serious, recirculated water interrupts circulation, makes dedusting fan
Bearing damages because can not get cooling down normally, affects dedusting fan dedusting.Traditional recirculated water
Failure of pump judges to rely on artificial continual tour, observes cooling Water Sproading pipe and cooling water
Cooling aqueous condition in tank, although the method is reliable, but inefficiency, however not excluded that
Because other interference factor can not find fault in time.
Summary of the invention
It is an object of the invention to provide a kind of dedusting fan bearing cooling water and cut off the water supply automatically-monitored
Alarm, can automatically send failure alarm signal, thus find in time when water circulating pump is cut off the water supply
Fault, it is to avoid because of the damage dedusting fan bearing of cutting off the water supply of recirculated cooling water, just affecting dedusting fan
Often operating, it is possible to the smooth and easy situation of Full-automatic monitoring bearing cooling water, it is not necessary to manually see and regard, from
And improve the reliability of work, improve the work efficiency of employee.
The technical scheme is that
A kind of dedusting fan bearing cooling water is cut off the water supply automatically-monitored alarm, including bracing frame,
Equalizer bar, hanger wire, balancing weight, dust-collecting bucket, travel switch, electric bell and frizzen, described
The upper end of bracing frame is rotationally connected with the middle part of described equalizer bar, and described balancing weight and dust-collecting bucket lead to
Crossing described hanger wire and be separately mounted to the two ends of described equalizer bar, described travel switch is arranged on institute
Stating the side of bracing frame, described electric bell is connected with described travel switch, and described frizzen is installed
Near the side of described balancing weight on described equalizer bar, the termination of described frizzen is to described
Travel switch；The bottom of described dust-collecting bucket is provided with mesh, the cooling current in cooling Water Sproading pipe
Entering in described dust-collecting bucket, described dust-collecting bucket is placed in the top of cooling water tank.
Described dedusting fan bearing cooling water is cut off the water supply automatically-monitored alarm, wherein said net
The sectional area sum in hole is less than 1/3rd of the sectional area cooling down Water Sproading pipe.
The invention have the benefit that the dedusting fan bearing cooling water of the present invention is cut off the water supply automatization
Monitoring alarm, can automatically send failure alarm signal when water circulating pump is cut off the water supply, thus in time
Find fault, it is to avoid because of the damage dedusting fan bearing of cutting off the water supply of recirculated cooling water, affect dedusting wind
Machine runs well, it is possible to the smooth and easy situation of Full-automatic monitoring bearing cooling water, it is not necessary to manually see and regard,
Thus improve the reliability of work, improve the work efficiency of employee.
Accompanying drawing is invented
Fig. 1 is that dedusting fan bearing cooling water is cut off the water supply automatically-monitored alarm arrangement figure.
Detailed description of the invention
The automatically-monitored alarm as it is shown in figure 1, a kind of dedusting fan bearing cooling water is cut off the water supply,
Including bracing frame 1, equalizer bar 2, hanger wire 3, balancing weight 4, dust-collecting bucket 5, travel switch
6, electric bell and frizzen 7, the upper end of support frame as described above 1 turns with the middle part of described equalizer bar 2
Being dynamically connected, described balancing weight 4 and dust-collecting bucket 5 are separately mounted to described by described hanger wire 3
The two ends of equalizer bar 2, described travel switch 6 is arranged on the side of support frame as described above 1, described
Electric bell is connected with described travel switch 6, and described frizzen 7 is arranged on described equalizer bar 2
Near the side of described balancing weight 4, the termination of described frizzen 7 is to described travel switch 6；
The bottom of described dust-collecting bucket 5 is provided with mesh, and the cooling water in cooling Water Sproading pipe 8 flows into described
In dust-collecting bucket 5, described dust-collecting bucket 5 is placed in the top of cooling water tank 9.Described mesh
Sectional area sum is less than 1/3rd of the sectional area cooling down Water Sproading pipe 8.
Above-mentioned dedusting fan bearing cooling water automatically-monitored alarm work principle of cutting off the water supply is as follows:
The cooling water returned injects in dust-collecting bucket 5 by cooling Water Sproading pipe 8, when normally working,
Cooling water in dust-collecting bucket 5 flows into cold by top overflow and bottom mesh infiltration two ways
But in water tank 9.When cooling down water and terminating circulation, the cooling water of top overflow terminates, catchments
Cooling water in bucket 5 is all penetrated in tank 9 by bottom mesh, the now weight of balancing weight 4
Amount is more than the weight of dust-collecting bucket 5, and balancing weight 4 sinks, and equalizer bar 2 rotates frizzen counterclockwise
Travel switch 6 is triggered in the termination of 7, the electric bell energising the tinkle of bells linked together with travel switch 6
Alarm sounds.The sectional area sum of mesh less than cooling Water Sproading pipe 8 sectional area three/
One, during cooling water normal circulation, it is ensured that the cooling water in dust-collecting bucket 5 is full all the time, catchments
The gross weight (dust-collecting bucket 5 own wts+water weight) of bucket 5, more than the weight of balancing weight 4, is kept away
The error exempting from travel switch 6 triggers.
