Preferably, dividing plate 4 slides up and down with main body 1 is connected and the two sealing joint strip sealed set so that dividing plate 4 up and down
Height-adjustable, no height is set for different vapor situations, the vapor of high impurity, can highly be reduced, is protected
Card particulate matter fully precipitate, the vapor of low impurity can lift the height of dividing plate 4, be more beneficial for vapor quickly through；It is more excellent
Selection of land, the upper surface of main body 1 are provided with two groups of scroll wheels 7, dividing plate 4 be located between one group of two be oppositely arranged roller and with its phase
Setting is cut, two groups of scroll wheels 7 are located at the both ends of dividing plate 4,；Two groups of scroll wheels 7 are driven by two drive links 8 respectively, and two
Individual drive link 8 is driven by the second gear 9 engaged with first gear 10, and first gear 10 is driven by motor 11 to be rotated
Or can be manually rotated, drive link 8 in the upper surface of main body 1, sets the regulation knot of dividing plate by the solid lock of fixed seat 12 of rotation connection
Structure, it is more efficient and convenient, it can fine-tune, the different height of dividing plate 4 is set, and is more pacified for the operation of high temperature dummy plate 4
Entirely, avoid directly contacting under high temperature and damage, the security of lifting operation.
During the use of reality, energy recovery assemblies away from as follows：Reduction furnace soaking zone contains a large amount of of heat
High-temperature steam is quickly collected into main delivery pipe in the presence of the first air-introduced machine 61 and the second air-introduced machine 62, and to heat
Zinc-plated part carries out heat supply, realizes the collection of heat, and the regulation of high-temperature steam flow passes through first flow regulating valve 67 and the
Two flow control valves 68 realize, the regulation of high-temperature steam degree of purity is by the first drain valve 69 and the second drain valve 70 come real
It is existing, temperature inductor 651 is set by the port of export of main delivery pipe 65, the temperature of the high-temperature steam of injection can be supervised immediately
To survey, and feed back to electric cabinet 71, be adjusted immediately, the heat recovery that total realizes reduction furnace soaking zone recycles,
Then heat supply is carried out to galvanizing position, saves the energy；The operation principle of hydrophobic valve protection assembly is as follows：Vapor is entrainment of pipe
Corrosion particulate matter in road is blown on dividing plate 4, due to having the stop of dividing plate 4 so that particle can be deposited to the bottom of filter chamber 20,
The inside of filtered fluid 5 is deposited over, because the bottom of main body 1 is detachable and sealed set bottom plate, when corrosion particle
When thing is excessive, bottom plate can be opened and in time discharge particulate matter, facilitate it is follow-up continue to purify, after crossing filtered fluid 5,
Pure vapor enters drain valve 6, then smoothly discharges steam condensation Cheng Shuihou, and this structure reduces the stifled of drain valve
Phenomenon is filled in, has ensured that the water water hair moment is in normal working condition, has reduced the maintenance number of drain valve, this knot is set
Before structure, less than three months, drain valve just needed cleaning maintenance once, increases this mechanism and reaches, 3 years cleaning and maintenances of drain valve are once
, the service life of drain valve is substantially prolongs, reduces the waste of the energy；The principle of gas improvement component is as follows：Nitrogen
Add to the inside of stove nose 85 by nitrogen gas delivery-line 81 and hydrogen delivery tube road 82 respectively with hydrogen, ensure at stove nose 85
Discharged after full combustion of gas, can be according to the situation of Actual combustion, by setting the first pressure-reducing valve 811, the and of the first regulating valve 812
First flowmeter 813, the second pressure-reducing valve 821, the second regulating valve 822 and second flowmeter 823 set the ratio of nitrogen and hydrogen,
Ensure the full combustion of gas of gas discharge outlet at stove nose 85, avoid waste gas discharge and environment is polluted, more safety collar
Protect, and fully after burning, it is ensured that gas excludes in time, avoids strip herein from producing oxidation, improves the quality of strip,
Strip one end is avoided because oxidation produces waste material, product utilization rate is lifted, reduces cost；Above so that the total of reduction furnace
More safe efficient and stable performance, service life length.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All equivalent changes made according to the present patent application scope and improvement
Deng, all should still belong to the present invention patent covering scope within.
