Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle for producing high-temperature antioxidants from metals. Background Art
[0002] During hot rolling of steel, since the billet is in a high temperature environment, an oxidation reaction occurs between the billet and the air, forming a layer of iron oxide on the surface of the billet, and this part of the steel will be lost. The total amount of steel destroyed by high temperature oxidation every year is huge, resulting in a large amount of economic waste. Therefore, people have developed metal high-temperature antioxidants; before the billet enters the furnace, the antioxidant is sprayed on the surface of the billet to protect the billet and prevent oxidation in the furnace, reducing the burning rate in the entire production process; the coating has a maximum heat shock resistance temperature of more than 1,300 degrees, which is suitable for hot rolling and processing and forging processes, bringing huge social and economic benefits.
[0003] For example, a metal high-temperature antioxidant produced by our company is prepared from a binder, a carrier liquid and a base material; the binder is a modified silica sol, the carrier liquid is water, and the base material includes Al2O3, SiO2, ZrO2, TiO2, CaO and B2O3, etc. After use, a coating protective film is formed on the surface of the steel billet to block the oxidation reaction between the air and the surface of the steel, which can increase the steel yield by 2-4% and reduce the loss of steel. The metal high-temperature antioxidant exists in the form of a coating, and a reactor is required in its preparation process to mix and react the raw materials. Among them, the added base material is a solid powder, which falls directly after being added to an ordinary reactor, and is easy to sink to the bottom, resulting in uneven mixing of the raw materials, affecting the final product effect. Therefore, based on many years of experience in coating production, our company has made targeted improvements to the reactor to solve the problems of raw material sinking to the bottom and uneven mixing in conventional devices.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0044] Reference Figure 1-13 A reactor for producing high-temperature antioxidants from metals comprises a reactor body 1 provided with a top cover 11 and a stirring mechanism arranged in the reactor body 1.
[0045] The stirring mechanism includes: a main shaft 2 extending downward through the top cover 11 , and a multi-layer stirring blade 3 mounted on the main shaft 2 .
[0046] Correspondingly, after the main shaft 2 passes through the top of the top cover 11, it is connected to the power assembly through transmission; preferably, a pulley 21 is provided above the main shaft 2 for connecting power.
[0047] At the same time, springs 4 sleeved on the main shaft 2 are respectively arranged between adjacent layers of stirring blades 3 and above the uppermost layer of stirring blades 3 .
[0048] like Figure 2 , 3 As shown in , 4 and 6, the stirring blade 3 is moved up and down and reset by the cooperation between the stirring blade 3 and the spring 4, so that the mixed material can be operated with different stirring blade spacings.
[0049] Correspondingly, a bottom baffle plate and an upper baffle plate fixed on the main shaft 2 are respectively provided below the main shaft 2 and above the uppermost spring 4 to limit the moving range of the stirring blade 3 and the spring 4.
[0050] In some embodiments, the stirring blade 3 is composed of a plurality of inclined blades 32 surrounding a central tube 31; the inclination shapes of the inclined blades 32 are consistent; at the same time, keys and keyways that cooperate with each other are correspondingly provided on the central tube 31 and the main shaft 2; the central tube 31 slides vertically on the main shaft 2.
[0051] The inclined blades 32 form an inclined section; when working in the forward direction, the mixed liquid is moved upward; Figure 8 , 9 As shown, the stirring blade 3 rotates clockwise, and the mixed liquid is pushed upward by the inclined blade 32.
[0052] It should be noted that the inclined blades 32 of the stirring blades 3 of adjacent layers may be staggered; Figure 6 As shown, the inclined blades 32 of adjacent layers are arranged at staggered positions.
[0053] In some embodiments, the outer sides of the bottom baffle and the upper baffle are respectively connected to the outer ring 5 through the extension rod 51; a plurality of vertical rods 52 are arranged between the upper and lower outer rings 5. At the same time, a long impeller 53 arranged vertically and avoiding the stirring blade 3 is fixedly arranged on the vertical rod 52.
[0054] The stirring blade 3 has a hole for the vertical rod 52 to pass through. Figure 2 , 3 , 4, 10, 12; in order to avoid the stirring blade 3, the vertical rod 52 is provided with one or two long impellers 53 according to its position.
[0055] It should be noted that the outer edge of the long impeller 53 is in contact with the inner wall of the reactor body 1; during operation, as the main shaft 2 rotates, the vertical rod 52 is driven by the outer ring 5; at the same time, under the impact of the mixed liquid, the long impeller 53 is moved to disturb the mixed liquid; at the same time, the long impeller 53 scrapes the inner wall of the reactor body 1 to scrape off the attachments and adhesions on it.
[0056] Preferably, the long impeller 53 is composed of a plurality of curved blades 54 arranged around it.
[0057] Furthermore, a hole 55 is provided on the curved blade 54 to reduce its own weight and make it easier to generate self-rotation.
[0058] Preferably, a fixing seat 56 adapted to the vertical rod 52 is provided on the lower end surface of the outer ring 5 of the upper layer and the upper end surface of the outer ring 5 of the lower layer; the vertical rod 52 is inserted into the fixing seat 56 and rotates.
[0059] In some embodiments, a lifting pipe 6 is disposed outside the reactor body 1 to pump the mixed liquid at the bottom to the top, and cooperate with the stirring blades 3 to enhance the mixing effect.
[0060] It should be noted that the lifting pipe 6 is equipped with a pump to provide power; and the lifting pipe 6 does not need to be in continuous operation; it can be operated intermittently to lift the bottom liquid.
[0061] The inlet of the lifting pipe 6 is connected to the bottom of the reactor body 1 , and the outlet is connected to the upper part of the reactor body 1 .
[0062] Preferably, the outlet position of the riser 6 is higher than the internal liquid level.
[0063] It should be noted that when the stirring blade 3 is operating in the forward direction, the mixed liquid is pushed upward and each stirring blade 3 is pressed downward; when operating in the reverse direction, the mixed liquid is pushed downward and each stirring blade 3 is pushed up; during production, the rotation direction of the stirring blade 3 can be adjusted as needed.
[0064] In some embodiments, a plurality of feed pipes 12 are disposed above the top cover 11 to facilitate the addition of different raw materials. As shown in the accompanying drawings, two feed pipes 12 are disposed to add solid raw materials and liquid raw materials, respectively.
[0065] Preferably, a corresponding number of feed pipes 12 may be provided according to the type of raw materials; each feed pipe 12 is used to supply different raw materials.
[0066] In some embodiments, a hopper 7 is provided above the main shaft 2 to collect the feed to the middle position to prevent the raw materials from falling from only one position after entering from the feed pipe 12. The hopper 7 rotates with the main shaft 2, and the raw materials can be preliminarily mixed in the hopper 7.
[0067] It is understandable that, as the aggregate hopper 7 rotates, the raw materials will be directly thrown out, or partially accumulated in the aggregate hopper 7, and after reaching a certain amount, will roll to the edge; the rotation speed affects the effect produced, but both effects do not affect the preliminary mixing function.
[0068] Furthermore, a plurality of circles of through holes 72 are provided on the gathering hopper 7; when the raw materials are gathered, part of the raw materials fall through the through holes 72 and part of the raw materials continue to roll; while preliminary mixing can still be achieved, more comprehensive material coverage is achieved.
[0069] Preferably, the lower surface of the aggregate hopper 7 is provided with a support rod 71 whose lower end is fixed to the outer ring 5; Fig.13 As shown, the stability of the aggregate hopper 7 is improved by a plurality of support rods 71 .
[0070] When the utility model is used, the main shaft 2 rotates under the drive of external power; various raw materials are added through the feeding pipe 12 at the top; the raw materials first fall into the gathering hopper 7 for preliminary mixing and then fall; the various raw materials form a mixture, which is stirred by the stirring blades 3 and the long impeller 53 in the reactor body 1; according to the operating process, the main shaft 2 is controlled to run forward and reversely; at the same time, the lifting pipe 6 is intermittently started to flush the mixed liquid at the bottom to the top, so as to further enhance the mixing effect.
[0071] In the utility model, the multi-layer stirring blades 3 are mounted on the main shaft 2 and cooperate with the spring 4 to realize the up and down movement and resetting of the stirring blades 3, and to perform operations with different stirring blade spacings on the mixed material; cooperate with the positive direction operation to achieve good mixing operation; the inclined blades 32 of the stirring blades 3 form an inclined section, which pushes the mixed liquid upward during the positive operation and pushes the mixed liquid downward during the reverse operation; a long impeller 53 is arranged on the vertical rod 52, which is pushed by the impact of the mixed liquid, disturbs the mixed liquid, and scrapes the attachment and adhesion on the inner wall of the reactor body 1; a lifting pipe 6 is arranged to pump the mixed liquid at the bottom to the top, and cooperate with the stirring blades 3 to enhance the mixing effect; the raw materials are preliminarily mixed in the gathering hopper 7, and the material coverage is more comprehensive.
