The housing 100 is provided with a first driving mechanism 102, which can control the telescopic shell 200 to extend and retract. When the telescopic shell 200 is extended, the protrusion on the inner side of the telescopic shell 200 will not block the gap, so that the zinc vapor inside the rotating shell can enter the cleaning chamber, and the extension of the telescopic shell 200 can suck the zinc ash adsorbed on the inner wall of the rotating shell. When the telescopic shell 200 is contracted, the protrusion on the inner side of the telescopic shell 200 can block the gap, so that the cleaning chamber forms a closed space. The telescopic shell 200 is a metal bellows structure, and each wave crest of the bellows structure constitutes the protrusion. The size of the telescopic shell 200 is set so that each protrusion of the telescopic shell 200 can just correspond to and block the gap between each rotating shell.

[0034] In this way, during the hot-dip galvanizing process of the strip steel, the telescopic shell 200 is controlled to extend by the first driving mechanism 102, so that the protrusion on the telescopic shell 200 does not block the gap, so that the zinc vapor inside the rotating shell can enter the cleaning chamber, and excessive adsorption of zinc vapor on the inner wall of the rotating shell is avoided; at the same time, the extension of the telescopic shell 200 can absorb and adsorb the zinc ash condensed on the inner wall of the rotating shell, so as to achieve the cleaning and collection of the zinc ash; then, the telescopic shell 200 is controlled to contract by the first driving mechanism 102, so that the protrusion on the telescopic shell 200 can block the gap, so that the cleaning chamber forms a closed space, and the zinc ash can be cleaned by introducing gas into the cleaning chamber, thereby improving the cleaning effect of the zinc ash.

[0035] The first drive mechanism 102 is provided with two, and the two first drive mechanisms 102 can increase the telescopic speed of the telescopic shell 200 by synchronously operating. A metal fixing ring is provided on the top of the telescopic shell 200, and the output end of the first drive mechanism 102 is fixedly connected to the metal fixing ring. The telescopic length of the telescopic shell 200 is equal to the telescopic length of the output end of the first drive mechanism 102.

[0036] In one embodiment, each layer of rotating plates is provided with four, two rotating plates form a group, and the two rotating plates in the same group are respectively a first rotating plate 201 and a second rotating plate 202, and the first rotating plate 201 and the second rotating plate 202 are vertically arranged in the horizontal direction; the first rotating plate 201 and the second rotating plate 202 can both rotate around a horizontal axis, and the housing 100 is provided with two second driving mechanisms 101, and each second driving mechanism 101 can control a group of rotating plates to rotate synchronously. The first driving mechanism 102 and the second driving mechanism 101 are both electric cylinders.

[0037] In one embodiment, a first bevel gear 2012 is provided at one end of the first rotating plate 201, a second bevel gear 2022 is provided at one end of the second rotating plate 202, the first bevel gear 2012 and the second bevel gear 2022 of each set of rotating plates are provided correspondingly, and a double-sided rack 203 is provided at the output end of the second driving mechanism 101, the double-sided rack 203 extends in the up-down direction, and the two side surfaces of the double-sided rack 203 are respectively meshed with the first bevel gear 2012 and the second bevel gear 2022 of each set of rotating plates. The length of the double-sided rack 203 enables it to drive the upper and lower multi-layer rotating plates to rotate synchronously.

[0038] In one embodiment, the rotating shell includes four sealing plates 210 fixedly arranged on the housing 100, the sealing plates 210 are arranged vertically and in an L shape, and the sealing plates 210 are used to connect the first rotating plate 201 and the second rotating plate 202 arranged adjacently. The four sealing plates 210 correspond to the four right angles of the telescopic shell 200 respectively, and the right angles of the sealing plates 210 form an escape space for accommodating the first bevel gear 2012, the second bevel gear 2022 and the double-sided rack 203. This arrangement can prevent the first bevel gear 2012, the second bevel gear 2022 and the double-sided rack 203 from interfering with the telescopic shell 200.

[0039] In one embodiment, the length of the first rotating plate 201 extends in the left-right direction, the length of the second rotating plate 202 extends in the front-back direction, the left and right ends of the first rotating plate 201 are both provided with a first rotating shaft 2011, the front and back ends of the second rotating plate 202 are both provided with a second rotating shaft 2021, the sealing plate 210 includes a first fixed plate and a second fixed plate vertically arranged, the first rotating shaft 2011 is rotatably arranged on the first fixed plate and passes through the first fixed plate, the second rotating shaft 2021 is rotatably arranged on the second fixed plate and passes through the second fixed plate, the first bevel gear 2012 is arranged at the end of the first rotating shaft 2011, and the second bevel gear 2022 is arranged at the end of the second rotating shaft 2021. The length of the first rotating plate 201 is greater than the length of the second rotating plate 202.

[0040] In one embodiment, in the up-down direction, the first rotation axis 2011 is located in the middle of the first rotation plate 201, and the second rotation axis 2021 is located in the middle of the second rotation plate 202. This facilitates the first rotation plate 201 and the second rotation plate 202 to rotate.

[0041] In one embodiment, a first bending plate 2013 is provided at the bottom of the first rotating plate 201, and a second bending plate is provided at the bottom of the second rotating plate 202. The length of the first bending plate 2013 is equal to the length of the first rotating plate 201, and the length of the second bending plate is equal to the length of the second rotating plate 202.

[0042] The first rotating plate 201 can scrape off the zinc ash on the first fixed plate when rotating, and the zinc ash falls onto the first bending plate 2013. The second rotating plate 202 can scrape off the zinc ash on the second fixed plate when rotating, and the zinc ash falls onto the second bending plate, thereby improving the cleaning effect of the zinc ash on the sealing plate 210 and preventing the cleaned zinc ash from falling onto the surface of the strip.

[0043] In one embodiment, the housing 100 is provided with an air suction port 104 and an air blowing port 103, wherein the air blowing port 103 is located above the housing 100 and the air suction port 104 is located below the housing 100. The air blowing port 103 is connected to a hair dryer, and the air suction port 104 is connected to an exhaust fan, and both the air suction port 104 and the air blowing port 103 are connected to the cleaning chamber.

[0044] In one embodiment, a cover 150 is provided on the top of the housing 100, and an opening is provided on the cover 150, and the opening is communicated with the inside of the rotating shell. An insertion shell 140 is provided on the bottom of the housing 100, and the insertion shell 140 is communicated with the inside of the rotating shell. The insertion shell 140 is used to be inserted into the zinc liquid, and the sealing plate 210 is fixedly arranged on the insertion shell 140. The horizontal cross-section of the insertion shell 140 is smaller than the horizontal cross-section of the housing 100, so that the insertion shell 140 can block the bottom of the telescopic shell 200 and the rotating shell. The cover 150 can block the top of the telescopic shell 200 and the rotating shell, so that when the protrusion of the telescopic shell 200 blocks the gap between the rotating plates, the cleaning chamber can ensure a certain degree of sealing.

[0045] In one embodiment, the housing 100 includes an upper shell 110, a middle shell 120 and a lower shell 130 connected in sequence from top to bottom, the upper shell 110 and the middle shell 120 are fixedly connected by bolts, and the middle shell 120 and the lower shell 130 are fixedly connected by bolts. A soft connection part 111 is provided on the upper shell 110, and the soft connection part 111 enables the furnace nose to be bent, so as to adjust the direction of the furnace nose according to actual needs.

[0046] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0047] In the initial state, the telescopic shell 200 is in an extended state, the first rotating plate 201 and the second rotating plate 202 are both in a vertical state, and the first bent plate 2013 at the bottom of the first rotating plate 201 and the second bent plate at the bottom of the second rotating plate 202 are both located inside the rotating shell. The strip steel is placed inside the rotating shell, and the strip steel is inserted into the zinc liquid through the insertion shell 140 under the furnace nose, and the zinc vapor enters the cleaning chamber through the gap between the rotating plates.

[0048] Then, the telescopic shell 200 is further extended by the first driving mechanism 102, and the extension of the telescopic shell 200 can suck the zinc ash adsorbed on the inner wall of the rotating shell; thereby preventing the zinc ash from falling on the surface of the strip steel and improving the galvanizing production quality of the strip steel. Then, the telescopic shell 200 is contracted by the first driving mechanism 102, and the protrusion on the telescopic shell 200 can block the gap between the rotating plates, so that the cleaning chamber forms a closed space. Then, nitrogen is rushed into the cleaning chamber through the air blowing port 103, and the air flow can blow off and vibrate the zinc ash attached to the inner wall of the telescopic shell 200. Finally, the air suction port 104 is opened, so that the air suction port 104 can suck the gas and zinc ash in the cleaning chamber. In this way, excessive zinc vapor is prevented from gradually condensing into zinc ash after the inner wall of the rotating shell is cooled, thereby improving the cleaning effect of zinc ash.

[0049] After the first stage of zinc ash cleaning is completed, the second driving mechanism 101 is controlled to drive the double-sided rack 203 to move up and down, so that the first rotating plate 201 and the second rotating plate 202 are rotated 180 degrees around the horizontal axis, so that the side of the first rotating plate 201 and the second rotating plate 202 with zinc ash adsorbed thereon are rotated into the cleaning chamber. In addition, the first rotating plate 201 and the second rotating plate 202 can scrape the zinc ash adsorbed on the sealing plate 210 during the rotation process, and drop it onto the first bending plate 2013 and the second bending plate respectively. The first bending plate 2013 and the second bending plate are turned from bottom to top and from the inside of the rotating shell into the cleaning chamber, and the collected zinc ash is sent into the cleaning chamber, and then nitrogen is flushed into the cleaning chamber again. Under the action of the airflow, the zinc ash is cleaned for the second time, so that both sides of the first rotating plate 201 and the second rotating plate 202 can be cleaned, further improving the cleaning effect of the zinc ash.

[0050] Thus, the zinc ash inside the furnace nose can be continuously cleaned by controlling the first driving mechanism 102 and the second driving mechanism 101. In this way, the zinc ash can be cleaned without stopping the machine, thereby improving the production efficiency of hot-dip galvanizing of steel strips.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
