2
This cover is interior cover and overcoat.
The utility model has the advantages that:
Under the situation of ordinary production, in the watch-keeping cubicle, just can realize the automatic cleaning of camera lens and viewport knot ash, the works better of recovery imaging device by the Long-distance Control button of alarm controller.And, when system occur stopping the supple of gas or steam, when cutting off the water abnormal conditions, imaging lens also can be realized automatic protection.This is very easy to production, also provides possibility for promoting the top imaging technology on a large scale.
Description of drawings
Fig. 1 is the general illustration of this device.
Fig. 2 is Controlling System, gas, water, electric field control case 10, controlling alarm case 12 and the control cable of this device.
Embodiment
Be elaborated below in conjunction with Fig. 1,2 pairs of the utility model.
The automatic cleaning device of this blast furnace furnace roof infrared imaging camera lens mainly is made up of probe mounting seat 1, controlled tightness system, installation orienting sleeve 2, camera probe 6 and refractory seals pad etc.Controlled tightness system mainly is made up of movable sealing plate 4, topworks 5 and refractory seals etc.Controlled tightness system and camera probe 6 are to be installed on blast furnace 9 bodies of heater by mounting seat 1.
In use, in the appropriate location perforate of blast furnace 9 furnace roofs, mounting seat 1 by technical requirements and body of heater firm welding, is connected controlled tightness system, orienting sleeve, camera probe 6 covers and elevated-temperature seal part then with bolt.
Cover and overcoat in wherein the outside of camera probe 6 comprises successively wherein are formed with inner space 7, and are provided with internal layer air inlet port gas in the appropriate location of interior cover and are entered and camera probe 6 is cleaned by the internal layer air inlet port between camera probe 6 and interior cover.Form outer space 8 and between interior cover and overcoat, be provided with, and be provided with outer air inlet port in the appropriate location of overcoat, and gas by a layer air inlet port entered outer space 8 and camera probe 6 is cleaned.Certainly, also an overcoat can only be set in camera probe 6 outsides, and only be formed with a space.Yet, inside and outside two covers of preferable use, thus make the cleaning better effects if of air.
Probe internal layer and skin will feed gas, can be air, are preferably nitrogen.Preferably, the pressure 〉=4.5Kg/cm of gas
2And those skilled in the art can determine employed gas and pressure thereof according to field condition.
The front end of interior cover, overcoat, promptly the end in stove can be provided with opening, and the gas that is entered by inlet mouth can be entered in the stove through the front of camera probe 6, thereby reduces the possibility that in-furnace dust dirt accumulates in camera probe 6.When cleaning, because 4 sealings of movable sealing plate, and blow in sealing plate 4 reflections and forms turbulent flow by the air-flow that inside and outside cover blows out, this turbulent flow produces cleaning strong to camera probe 6 surfaces, and plays the effect of cleaning camera probe 6 surfaces.
Automatic cleaning device of the present utility model also can be provided with water-chilling plant, by the round-robin water coolant this device is cooled off, and prevents because high temperature and damage that device is caused.
Topworks 5 can also can be made of the mechanical mechanism of driven by motor by constituting as Hydraulic Elements such as cylinder or oil cylinders, constitutes as leading screw or tooth bar.Its effect is to drive movable sealing plate 4 to-and-fro movements, and the action of opening or closing.Wherein, the control of this topworks 5 is by the operator in watch-keeping cubicle 13 control, its think need clean camera probe 6 in, the keying of control topworks 5, and cleaning.This topworks 5 also can link to each other with automatic control device, and work as controlling elements, temperature regulator as water, the perhaps pressure controller of gas, when detecting the pressure subcritical value of the temperature of water or gas, just start topworks 5 automatically movable sealing plate 4 is prevented that camera probe 6 from damaging because of high temperature.
Can be provided with refractory seals spare at movable sealing plate 4 with the position that contacts around it, prevent that so that movable sealing plate 4 is sealed the dust and other impurities in the blast furnace 9 from entering.
Gas, water, electric field control case 10, indoor controlling alarm case 12 connect by technical requirements.Because dust is very big in blast furnace 9 stoves, air-flow is complicated, through use after a while, camera lens and window place be knot ash gradually just, and more and more serious even camera lens and window are blocked and have a strong impact on observation to the working of a furnace.At this moment,, operator are necessary camera probe 6 is cleaned, just the button on the 12 li operation controls in watch-keeping cubicle makes topworks's 5 actions of tightness system and drives sealing plate 4, and it is closed if thinking.Make it the knot ash of camera lens and window produced strong cleaning because the pressure in the air chamber 3 increases rapidly and produces disorderly air-flow this moment.Through cleaning after a while, it is clean with the cleaning of the dust on the camera probe 6 that operator think, just operates push button again topworks's 5 actions and the drive sealing plate 4 of tightness system are opened.Pop one's head in this moment internal layer and outer field nitrogen blows out dust in camera probe 6 covers, camera lens is promptly cleaned totally as before, and it is normal that monitored picture recovers.This operates in the scene and also can realize.Simultaneously, when the air feed of system, supply water when overtemperature occurring in unusual or the probe sheath, Controlling System is reported to the police automatically and sealing plate 4 is cut out, and pick-up lens is realized protection automatically.
Referring to Fig. 2, the Controlling System of camera lens automatic cleaning device is formed: mainly be made up of field control unit and indoor remote control unit two portions.Can operate at the scene and can be in indoor realization Long-distance Control.This Controlling System can realize the automatic cleaning and the automatic protection functions of pick-up lens, and this is to the stable performance of total system and easy to maintenancely provide technical guarantee.
The technical solution of the utility model is not only applicable to blast furnace, also applicable to other industrial furnaces, as cupola furnace, heat treatment kiln and brickkiln, ceramic with high temperature stoves such as kilns.
