Description

Technical Field

[0001] This application relates to the technical field of solid waste resource utilization, and in particular to a rotary kiln oxygen supplementation device for solid waste recycling. Background Technology

[0002] To conserve resources and prevent zinc-containing waste from polluting the environment, it is necessary to recycle and process solid waste materials such as zinc-containing sludge and zinc-containing tailings. High-temperature reduction roasting of these solid waste materials in a secondary zinc oxide rotary kiln can efficiently recover zinc. The oxygen supplementation lance is a core piece of equipment in the secondary zinc oxide rotary kiln production process. It is mainly used to supplement air or oxygen-enriched air into the high-temperature volatilization section of the kiln to ensure that zinc vapor is fully oxidized into zinc oxide aerosol. The effectiveness of the oxygen supplementation lance directly affects the zinc recovery rate, the grade of secondary zinc oxide, and the stability of the kiln operation.

[0003] Currently, oxygen supplementation nozzles are usually suspended on the kiln head platform and inserted into the kiln through the kiln opening on the kiln head hood inspection door. In order to allow the oxygen supplementation nozzle to be adjusted up and down and moved left and right, the kiln opening size is usually increased so that the oxygen supplementation nozzle can be manually adjusted to adjust the spray position. However, due to the increased kiln opening size, the flue gas inside the kiln can easily escape from the kiln opening, affecting flue gas dust collection. Cold air outside the kiln can also easily flow into the kiln, lowering the kiln temperature. Operators are also prone to high temperature burns. Therefore, there is an urgent need for an oxygen supplementation device that can both seal the kiln opening and not easily affect the movement of the oxygen supplementation nozzle. Summary of the Invention

[0004] In order to both seal the kiln opening and avoid affecting the movement of the oxygen supply nozzle, this application provides an oxygen supply device for a rotary kiln used in solid waste recycling.

The end of the flipping rod away from the flipping shaft is slidably disposed in a flipping sliding hole provided on the flipping plate. The flipping plate is slidably connected to the adjusting plate. Sliding the flipping plate allows the flipping rod to rotate 180 degrees around the axis of the flipping shaft.

[0010] Optionally, both ends of the flip plate are provided with flip support plates, which are connected to the adjustment plate and slidably connected to the flip plate. Two fixing bolts are threaded through one of the flip support plates, and a fixing hole is provided on the flip plate for the fixing bolts to be inserted.

The first adjustment section drives the support section to move, thereby adjusting the position of the oxygen supplementation nozzle. The support section, via multi-stage telescopic rods, synchronously drives the adjustment plate to move. The adjustment groove on the adjustment plate drives the adjustment block to move. When the adjustment plate moves laterally left and right, the adjustment groove adjusts the position of the clearance gap by driving all the sealing plates to move as a whole, allowing the clearance gap to be adjusted laterally along with the oxygen supplementation nozzle. When the adjustment plate moves up and down, the second adjustment section of the adjustment groove drives the sealing plate to move independently, allowing the clearance gap to be adjusted by increasing up and decreasing down or decreasing up and increasing down. Therefore, this application can both seal the kiln opening and avoid affecting the movement of the oxygen supplementation nozzle. During the adjustment of the injection position of the oxygen supplementation nozzle, the flue gas inside the kiln is less likely to escape from the kiln opening, and cold air from outside the kiln is less likely to flow into the kiln, thus reducing the risk of burns to operators.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses an oxygen supplementation device for a rotary kiln used in solid waste recycling. (Refer to...) Figure 1 An oxygen supplementation device for a rotary kiln used in solid waste recycling includes an oxygen supplementation nozzle 1, a support and adjustment assembly 2, and a sealing and adjustment assembly 3.

[0020] The adjustment assembly 2 includes a support part 21 and a first adjustment part 22.

[0021] The support 21 is set on the kiln head platform and is used to install the oxygen injection gun 1.

[0022] The first adjustment part 22 is connected to the support part 21. The first adjustment part 22 is used to drive the support part 21 to move in order to adjust the position of the oxygen injection gun 1, so that the oxygen injection gun 1 can move closer to or further away from the kiln opening, can move horizontally left and right, and can move up and down.

[0023] The sealing and adjusting assembly 3 includes a sealing part 31 and a second adjusting part 32.

[0024] Reference Figure 1 and Figure 2The sealing part 31 is symmetrically arranged in two sets on the two inspection door panels. The sealing part 31 includes multiple sealing plates 311 arranged in the vertical direction. The sealing plates 311 are slidably arranged on the inspection door panels in the horizontal direction. The plate surface of the sealing plate 311 is vertically arranged. The sealing plate 311 seals the kiln opening, and a clearance notch 3111 for the insertion of the oxygen injection gun 1 is formed between the sealing plates 311 of the two sets of sealing parts 31.

[0025] The second adjustment part 32 is provided in two sets, and corresponds one-to-one with the sealing part 31. The second adjustment part 32 is connected to the support part 21. The second adjustment part 32 is used to drive all the sealing plates 311 of the corresponding set of sealing parts 31 to slide, and the second adjustment part 32 is used to make the clearance notch 3111 move with the movement of the oxygen injection gun 1.

[0026] In use, the oxygen supply nozzle 1 is installed on the support 21 and inserted into the clearance notch 3111 left after the sealing plate 311 seals the kiln opening. The first adjustment part 22 drives the support 21 to move, so that the position of the oxygen supply nozzle 1 can be adjusted according to the oxygen supply needs in the rotary kiln. Since the second adjustment part 32 is connected to the support 21, the support 21 can synchronously drive the second adjustment part 32 to move when it is driven by the first adjustment part 22. The second adjustment part 32 can drive the sealing plate 311 to slide based on the movement path of the oxygen supply nozzle 1, so as to adjust the position of the clearance notch 3111. The clearance notch 3111 can move with the movement of the oxygen supply nozzle 1, realizing the follow-up adjustment of the clearance notch 3111. Thus, this application can seal the kiln opening without affecting the movement of the oxygen supply nozzle 1. During the process of adjusting the spray position of the oxygen supply nozzle 1, the flue gas in the kiln is not easy to escape from the kiln opening, the cold air outside the kiln is not easy to flow into the kiln, and the operator is not easy to be burned by high temperature.

[0027] Specifically, refer to Figure 2 The closed part 31 also includes a support frame 312 and a sliding rod 313.

[0028] The support frame 312 is fixed to the inspection door panel. Multiple sliding rods 313 are provided and fixed to the closing plate 311 one by one. The sliding rods 313 slide through the support frame 312.

[0029] The sealing plate 311 is slidably mounted on the support frame 312 via the sliding rod 313. The sliding rod 313 and the support frame 312 facilitate the sliding of the sealing plate 311 relative to the maintenance door panel.

[0030] Specifically, refer to Figure 3 The second adjustment part 32 includes an adjustment plate 321 and an adjustment block 322.

[0031] Reference Figure 1 and Figure 3The adjusting plate 321 is connected to the support part 21, and a first clearance groove 3211 is provided on one side. The adjusting plate 321 has an adjusting groove 3212 at the bottom of the first clearance groove 3211. The adjusting groove 3212 is connected to the first clearance groove 3211. The end of the sliding rod 313 away from the closing plate 311 is slidably disposed in the first clearance groove 3211. Multiple adjusting blocks 322 are provided and are fixedly connected to the end of the sliding rod 313 away from the closing plate 311. The adjusting blocks 322 are slidably disposed in the adjusting groove 3212. The adjusting groove 3212 is used to drive the adjusting blocks 322 to move to adjust the position of the clearance notch 3111.

[0032] Since the adjusting plate 321 is connected to the support part 21, the support part 21 can move the adjusting plate 321 synchronously when it moves the oxygen supplementing spray gun 1. This allows the moving path of the moving plate to be consistent with the moving path of the oxygen supplementing spray gun 1 without the need for detection feedback. Since the adjusting block 322 is slidably disposed in the adjusting groove 3212, when the adjusting plate 321 is moved, the adjusting block 322 can slide in the adjusting groove 3212. This allows the adjusting groove 3212 to drive the adjusting block 322 to move, allowing the sealing plate 311 to slide and adjust the position of the clearance notch 3111. This allows the clearance notch 3111 formed by the sealing plate 311 to move in accordance with the movement of the oxygen supplementing spray gun 1.

[0033] Specifically, refer to Figure 3 The adjustment groove 3212 includes a first adjustment section 3213, a second adjustment section 3214 and a third adjustment section 3215 arranged from top to bottom.

[0034] Reference Figure 1 and Figure 3 The first adjustment segment 3213 and the third adjustment segment 3215 are both straight and vertically arranged. The second adjustment segment 3214 is arc-shaped and is connected to the first adjustment segment 3213 and the third adjustment segment 3215 by arc transition. The clearance notch 3111 is formed by the sliding of the adjustment block 322 driven by the third adjustment segment 3215.

[0035] When the position of the oxygen supply spray gun 1 is adjusted by moving it left and right, the support part 21 drives the two adjustment plates 321 to move left and right in the same direction at the same distance, so that the adjustment groove 3212 can move left and right in sync. This allows the adjustment groove 3212 to drive the adjustment block 322 to move left and right in the same position, so that all the sealing plates 311 can move left and right in sync. This allows the clearance notch 3111 to adjust its position by moving left and right in sync with the oxygen supply spray gun 1.

[0036] When the position of the oxygen supply nozzle 1 is adjusted by lifting and lowering, the support part 21 drives the two adjusting plates 321 to move up and down synchronously, so that the adjusting groove 3212 can move up and down synchronously, and the second adjusting section 3214 can move up and down. When the adjusting block 322 slides from the first adjusting section 3213 or the third adjusting section 3215 into the second adjusting section 3214, the second adjusting section 3214 can drive the adjusting block 322 to make the corresponding closing plate 311 translate and increase the clearance gap 3111. When the adjusting block 322 slides from the second adjusting section 3214 into the first adjusting section 3213 or the third adjusting section 3215, the first adjusting section 3213 or the third adjusting section 3215 can drive the adjusting block 322 to make the corresponding closing plate 311 translate in the opposite direction and decrease the clearance gap 3111. Thus, under the synchronous change of the clearance gap 3111 increasing and decreasing, the position of the clearance gap 3111 can rise or fall synchronously with the oxygen supply nozzle 1.

[0037] Reference Figure 3 In order to enable the two sides of the sealing plate 311 to face the inside of the kiln alternately, the rotary kiln oxygenation device for solid waste recycling in this application also includes a turning assembly 4, which includes a turning shaft 41, a turning rod 42 and a turning plate 43.

[0038] The sliding rod 313 is in the shape of a circular rod, the adjusting block 322 is in the shape of a ball, and there is space between the inspection door panel and the sealing plate 311 for the sealing plate 311 to rotate 180 degrees.

[0039] Multiple flip shafts 41 and flip rods 42 are provided, and each corresponds to an adjustment block 322. One end of the flip shaft 41 is fixedly connected to the side of the adjustment block 322 away from the sliding rod 313. A second clearance groove 3216 is provided on the adjustment plate 321 for the flip shaft 41 to slide with the adjustment block 322. The second clearance groove 3216 is connected to the adjustment groove 3212.

[0040] The other end of the flip shaft 41 is fixedly connected to the flip rod 42. The flip rod 42 is a circular rod and is bent at 90 degrees. The end of the flip rod 42 away from the flip shaft 41 is slidably disposed in the flip sliding hole 431 opened on the flip plate 43. The flip plate 43 is slidably connected to the adjusting plate 321. The sliding direction of the flip plate 43 is towards or away from the inspection door panel. Sliding the flip plate 43 can make the flip rod 42 rotate 180 degrees around the axis of the flip shaft 41.

[0041] The axial direction of the flipping rod 42 near the flipping shaft 41 is perpendicular to the axial direction of the flipping shaft 41, and the axial direction of the flipping rod 42 away from the flipping shaft 41 is parallel to the axial direction of the flipping shaft 41. The end of the flipping rod 42 away from the flipping shaft 41 can rotate within the flipping sliding hole 431, and the end of the flipping rod 42 away from the flipping shaft 41 can slide within the flipping sliding hole 431 in a direction parallel to the axial direction of the flipping shaft 41.

[0042] When it is necessary to flip the sealing plate 311, slide the flipping plate 43, and the flipping sliding hole 431 moves with the flipping plate 43. The side wall of the flipping sliding hole 431 pushes the flipping rod 42 to rotate around the axis of the flipping shaft 41. The flipping rod 42 can drive the sealing plate 311 to rotate through the flipping shaft 41, the adjusting block 322 and the sliding rod 313, so that the sealing plate 311 can rotate 180 degrees with the flipping rod 42, thereby allowing the side of the sealing plate 311 facing the inside of the kiln to be flipped and switched.

[0043] Reference Figure 3 In order to facilitate fixing the position of the flip plate 43 after sliding, flip plate 44 is provided at both ends of the flip plate 43. The flip plate 44 is fixedly connected to the adjusting plate 321, and the flip plate 44 is slidably connected to the flip plate 43. The flip plate 43 is slidably connected to the adjusting plate 321 through the two flip plates 44.

[0044] Reference Figure 3 and Figure 4 Two fixing bolts 45 are threaded through one of the flip support plates 44, and a fixing hole 432 for the fixing bolts 45 to be inserted is opened on the flip plate 43. When the fixing hole 432 moves from the position opposite to one of the fixing bolts 45 to the position opposite to the other fixing bolt 45, the closing plate 311 rotates 180 degrees.

[0045] After the flip plate 43 drives the closing plate 311 to rotate into position, rotate the fixing bolt 45 so that the fixing bolt 45 can be inserted into the fixing hole 432. The fixing bolt 45 can fix the position of the flip plate 43 through the fixing hole 432, so that the state of the closing plate 311 after flipping is easy to stabilize.

[0046] Reference Figure 1 and Figure 2 In order to prevent the connection between the support part 21 and the adjusting plate 321 from affecting the support part 21's ability to move the oxygen injection gun 1 closer to or away from the kiln opening, two multi-stage telescopic rods 5 are connected to the support part 21. The movable ends of the multi-stage telescopic rods 5 are detachably connected to the adjusting plate 321 through the connecting assembly 6.

[0047] The support part 21 can drive the adjustment plate 321 to move horizontally and vertically through the multi-stage telescopic rod 5. Since the length of the multi-stage telescopic rod 5 can be adjusted by telescopic extension, the distance between the support part 21 and the adjustment plate 321 can be adjusted. Therefore, when the support part 21 is close to or far from the kiln opening, the support part 21 is less likely to affect the position of the adjustment plate 321.

[0048] Specifically, refer to Figure 2 The connecting component 6 includes a slot 61 and a chuck 62.

[0049] Reference Figure 1 and Figure 2 Two slots 61 are symmetrically arranged and are slidably arranged on the adjusting plate 321 in a sliding direction that is close to or far from each other. The two slots 61 are bolted together, and the chuck 62 is fixedly connected to the movable end of the multi-stage telescopic rod 5. The chuck 62 is engaged in the two slots 61.

[0050] When the two slots 61 are bolted together, the two slots 61 are in a fixed state relative to the adjusting plate 321.

[0051] After removing the bolts between the two slots 61, the two slots 61 can slide in a direction away from each other, allowing the chuck 62 to disengage from between the two slots 61. This makes it easy to disassemble the movable end of the multi-stage telescopic rod 5 from the adjusting plate 321, thus facilitating the opening of the maintenance door when production stops.

[0052] Specifically, refer to Figure 5 The support part 21 includes an adjustment frame 211, a first adjustment platform 212, and a second adjustment platform 213.

[0053] The adjusting frame 211 is slidably mounted on the kiln head platform, and the sliding direction of the adjusting frame 211 is towards or away from the kiln opening; the first adjusting platform 212 is horizontally slidably mounted on the adjusting frame 211, and the sliding direction of the first adjusting platform 212 is perpendicular to the sliding direction of the adjusting frame 211; the second adjusting platform 213 is vertically slidably mounted on the first adjusting platform 212, and two clamps 214 are fixedly connected to the second adjusting platform 213 for fixing the oxygen injection gun 1.

[0054] In this embodiment, refer to Figure 1 , Figure 2 and Figure 5 Two multi-stage telescopic rods 5 are fixedly connected to the second adjustment platform 213, and the second adjustment platform 213 drives the adjustment plate 321 to move through the multi-stage telescopic rods 5.

[0055] By sliding the adjusting bracket 211, the oxygen injection gun 1 can be moved closer to or further away from the kiln opening; by sliding the first adjusting platform 212, the oxygen injection gun 1 can be moved horizontally left and right; by sliding the second adjusting platform 213, the oxygen injection gun 1 can be raised and lowered up and down, so that the position of the oxygen injection gun 1 can be easily moved and adjusted in three directions.

[0056] Specifically, refer to Figure 5 The first adjustment unit 22 includes a power wheel 221, a first adjustment cylinder 222, and a second adjustment cylinder 223.

[0057] There are four drive wheels 221, all of which are rotatably connected to the adjusting frame 211. All drive wheels 221 are used to make the adjusting frame 211 roll and slide relative to the kiln head platform. The drive wheels 221 are connected to the drive motor 2211, which is fixedly connected to the adjusting frame 211. The output shaft of the drive motor 2211 is fixedly connected to the drive wheel 221.

[0058] The first adjusting cylinder 222 is fixedly connected to the adjusting frame 211, the movable end of the first adjusting cylinder 222 is fixedly connected to the first adjusting platform 212, the second adjusting cylinder 223 is fixedly connected to the first adjusting platform 212, and the movable end of the second adjusting cylinder 223 is fixedly connected to the second adjusting platform 213.

[0059] The power motor 2211 can drive the power wheel 221 to rotate, and the power wheel 221 can drive the adjustment frame 211 to move, so that the adjustment frame 211 can move closer to or further away from the kiln opening. The first adjustment cylinder 222 can drive the first adjustment platform 212 to move horizontally left and right with the adjustment frame 211 as support. The second adjustment frame 211 can drive the second adjustment platform 213 to move up and down with the first adjustment platform 212 as support. Since the oxygen injection gun 1 is installed on the second adjustment platform 213, it is convenient to drive the oxygen injection gun 1 to adjust its position.

[0060] The implementation principle of the rotary kiln oxygen supplementation device for solid waste recycling in this application embodiment is as follows: During use, the power motor 2211, the first adjusting cylinder 222, and the second adjusting cylinder 223 work together to drive the second adjusting platform 213 to move, thereby adjusting the position of the oxygen supplementation nozzle 1. The second adjusting platform 213 drives the adjusting plate 321 to move. When the adjusting plate 321 moves laterally left or right, it drives all its corresponding closed plates 311 to move synchronously and in the same direction with the same displacement, allowing the clearance notch 3111 to be adjusted laterally with the oxygen supplementation nozzle 1. When the adjusting plate 321 moves up and down, the second adjusting section 3214 of the adjusting groove 3212 can drive the adjusting block 322 to move, so that the clearance gap 3111 moves up and down in a way that increases above and decreases below or decreases above and increases below. This allows the clearance gap 3111 to be adjusted up and down with the oxygen injection gun 1. Thus, this application can both seal the kiln opening and not easily affect the movement of the oxygen injection gun 1. During the process of adjusting the injection position of the oxygen injection gun 1, the flue gas in the kiln is not easy to escape from the kiln opening, the cold air outside the kiln is not easy to flow into the kiln, and the operators are not easy to be burned by high temperature.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
