Detailed Description
The present invention will be further described with reference to the accompanying drawings.
An electric fire monitor for a coke-oven plant as shown in the attached figures 1 to 9 comprises a monitor box body 1, wherein an exhaust fan 2 is arranged above the monitor box body 1, and the air inlet end of the exhaust fan 2 is communicated with the inside of the monitor box body 1. And the air outlet end of the exhaust fan 2 is communicated with the outside. The inside humidity transducer 3 that is provided with of watch-dog box 1, the air exhauster 2 with 3 signal connection of telecommunication of humidity transducer, when humidity transducer 3 detected the inside humidity of watch-dog box 1 too big, 2 work of humidity transducer 3 control air exhauster, the hydrofuge of bleeding.
The below of watch-dog box 1 is provided with ventilation chamber 4, the top of ventilation chamber 4 is provided with a plurality of fresh air inlets 5, and is a plurality of fresh air inlets 5 are close to the edge setting, make the air that gets into can be comparatively even through watch-dog box 1 inner region, promote the exhaust dehumidification effect. The center of the bottom end of the ventilation chamber 4 is provided with a ventilation hole 6 communicated with the outside, so that the air entering from the outside can be uniformly dispersed to each air inlet hole 5; a moisture filtering device 7 is arranged in the ventilation hole 6, the moisture filtering device 7 is connected with the humidity sensor 3 through an electric signal, and the humidity sensor 3 controls the exhaust fan 2 to work and also drives the moisture filtering device 7 to work.
The moisture filtering device 7 comprises an annular filtering head 8, an airflow guide ring 9, an air drying air flue 10 and a small-sized fan 11, wherein the annular filtering head 8, the airflow guide ring 9, the air drying air flue 10 and the small-sized fan 11 are combined with each other through corresponding clamping and mounting structures and are mounted in the ventilation hole 6, and the structures are omitted in the attached drawings. The annular central shaft of the annular filter head 8 is vertical, the inside of the annular filter head 8 is divided into a plurality of arc-shaped filter cavities 12 at equal angles along the circumferential direction, and the arc-shaped filter cavities 12 are vertically arranged; the lower extreme and the external intercommunication of arc filter chamber 12, and the lower extreme is provided with the dehumidification sponge piece, makes arc filter chamber 12 when absorbing the outside air, can dehumidify the moisture absorption of sponge piece simultaneously to the humidity of outside air is still great when preventing that pumping fan 2 from bleeding the dehumidification, influences the dehumidification effect of air exhauster 2.
The airflow guide ring 9 is rotatably arranged above the annular filter head 8, and the humidity sensor 3 controls the rotation of the airflow guide ring 9. The inside of airflow guide ring 9 is provided with a plurality of ventilation water conservancy diversion chambeies 13 and a plurality of air-dry water conservancy diversion chamber 14 along the circumferencial direction interval, and is a plurality of ventilation water conservancy diversion chamber 13 and a plurality of air-dry water conservancy diversion chamber 14 all do not communicate each other. One end of the ventilation diversion cavity 13 is communicated with the arc-shaped filter cavity 12, and the other end of the ventilation diversion cavity 13 is communicated with the ventilation chamber 4; one end of the air drying diversion cavity 14 is communicated with the arc-shaped filtering cavity 12, and the other end of the air drying diversion cavity 14 is communicated with the air drying air passage 10; the small fan 11 is arranged in the air drying air passage 10. The small fan 11 will air-dry the dehumidification filter block in the arc filter chamber 12 that corresponds the intercommunication through air-drying air flue 10, ventilation water conservancy diversion chamber 13 during operation.
When the arc-shaped filter cavity 12 is communicated with the ventilation diversion cavity 13, the dehumidification sponge block is in a working state; when the arc-shaped filter cavity 12 is communicated with the air drying diversion cavity 14, the dehumidifying sponge block is in a dehumidifying state. Every time the moisture filtering device 7 works, the airflow guide ring 9 can rotate once, so that the dehumidifying sponge block is switched between the dehumidifying state and the working state. The dehumidification sponge blocks are thus divided into two groups which work alternately, one with the other air dried, so that the overall moisture filter device 7 can work continuously.
The air drying air passage 10 is arranged in the hollow part of the annular filter head 8, and the air drying air passage 10 comprises a communication chamber 15 and a vertical air duct 16; the small fan 11 is specifically positioned in the vertical air duct 16; the bottom end of the communicating chamber 15 is connected with the vertical air duct 16, the upper portion of the communicating chamber 15 is provided with a transverse air hole 17 and communicated with the air drying diversion cavity 14, a small motor 18 is arranged above the communicating chamber 15, and an output shaft of the small motor 18 penetrates through the top end of the communicating chamber 15 to be in transmission connection with the small fan 11. When the humidity sensor 3 detects that the humidity in the monitor case 1 is too high, the small-sized motor 18 is turned into an operating state by the signal transmission of the humidity sensor 3.
The lower end of the vertical air duct 16 does not exceed the lower end of the annular filter head 8, and the lower end of the annular filter head 8 is provided with a circular metal dust filter net 19. The metal dust filtering net 19 is mainly used for filtering dust and large-particle impurities, the circular metal dust filtering net 19 also plays a role in filtering the vertical air duct 16, and the structure is more reasonable.
An annular rack 20 is arranged above the airflow guide ring 9, a rack motor 21 is arranged in the ventilation chamber 4, an output shaft of the rack motor 21 is in transmission connection with the annular rack 20, and the rack motor 21 is in electrical signal connection with the humidity sensor 3. When the humidity sensor 3 detects that the humidity in the monitor box 1 is too high, the rack motor 21 works under the control of the humidity sensor 3 and drives the annular rack 20 to rotate, so that the chamber correspondingly communicated with the arc-shaped filter cavity 12 is switched between the ventilation diversion cavity 13 and the air drying diversion cavity 14.
The exhaust fan 2 is located outside the monitor box body 1, and the exhaust fan 2 is communicated with the inside of the monitor box body 1 through an air inlet pipe 22. The air-supply line 22 is for leaking hopper-shaped, just the air-supply line 22 is located the center department on watch-dog box 1 top, with the cooperation of fresh air inlet 5 makes external air current more disperse and even in watch-dog box 1, and the air current passes the box whole and reduces the dead angle, drives the moisture in the watch-dog box 1 from the air exhauster discharge to the external world more effectively.
A box door 23 is hinged on the monitor box body 1, and an anti-static net 24 is arranged on the rear surface of the box door 23. Because electrical apparatus fire monitoring equipment's box is the metal material, produces static easily, and contains more circuit component in the box, what electronic equipment was afraid of is exactly static, and static can bring random trouble for supervisory equipment normal operating, still can lead to some components to destroy sometimes, is unfavorable for the use, sets up and prevents that static electric wire netting 24 can effectively prolong equipment life-span.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
