Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature melting treatment equipment for fly ash, specifically relating to a high-temperature melting treatment device for fly ash. Background Technology

[0002] The high-temperature melting treatment device for fly ash mainly includes a furnace, fly ash conveying equipment, a temperature control system, and waste gas treatment equipment. First, the fly ash is conveyed into the furnace for processing. The furnace has a very high internal temperature, which rapidly melts and processes the fly ash. Under the furnace's control system, the temperature can be precisely controlled to ensure that the fly ash is fully treated. After processing, the resulting waste gas is purified by the waste gas treatment equipment to ensure that the treatment process does not have an impact on the environment.

[0003] For the authorization announcement number: CN 210586334 A high-temperature melting treatment device for fly ash includes a melting furnace. A feed pipe is installed through the top of the melting furnace, and a discharge pipe is installed through the side wall of the melting furnace. An extension pipe is installed through one end of the feed pipe inside the melting furnace, and a movable plate is movably sleeved on the outside of the extension pipe. The movable plate is slidably disposed against the inner side wall of the melting furnace, and an abutment plate is provided at the upper end of the movable plate. One end of a support spring is fixedly disposed at the upper end of the movable plate, and the other end of the support spring is fixedly disposed on the inner top wall of the melting furnace. A sealing plate matching the abutment plate is provided inside the melting furnace, and the sealing plate is movably inserted into a vertical support plate. The vertical support plate is fixedly disposed on a horizontal support plate, and the horizontal support plate is fixedly disposed on the outer side wall of the extension pipe. A return spring is wound around the sealing plate, and the two ends of the return spring are respectively fixedly disposed on the side wall of the sealing plate and the side wall of the vertical support plate. The sealing plate is movably inserted into the extension pipe, and a sealing groove matching the sealing plate is formed on the inner side wall of the extension pipe.

[0004] While the aforementioned application can achieve quantitative feeding of fly ash during processing, avoiding the risk of explosion due to excessive fly ash during high-temperature melting, the feeding amount is fixed. This means the thickness of the moving plate is fixed, and only a fixed amount of fly ash can be intermittently poured in. The thickness of the moving plate cannot be adjusted, making it difficult to adjust the amount of fly ash poured in intermittently according to different situations, greatly reducing its applicability. Therefore, a high-temperature melting fly ash processing device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature melting treatment device for fly ash, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature melting treatment device for fly ash, comprising a melting furnace, a feed pipe fixed at the top feed inlet of the melting furnace, an extended square pipe fixedly connected to the bottom end of the feed pipe, a limit sleeve fixedly connected to the outside of the extended square pipe, and a movable plate movably sleeved on the outside of the extended square pipe, the movable plate sliding on the inside of the melting furnace.

[0007] It also includes an intermittent sealing structure and a material quantity adjustment structure. The intermittent sealing structure is installed on the top of the moving plate and connected to the inner bottom wall of the melting furnace and the extended square tube. After the fly ash enters the melting furnace, the intermittent sealing structure can push the moving plate to move upward and cause the material to stop in the extended square tube.

[0008] The material quantity adjustment structure is installed at the bottom of the movable plate and connected to the extended square tube. The material quantity adjustment structure can facilitate the adjustment of the bottom height of the movable plate.

[0009] In a preferred embodiment, the intermittent sealing structure includes sealing plates that are movably inserted into the outer walls of both sides of the extended square tube. The top ends of the two sealing plates are fixed with return springs via connecting blocks, and the other ends of the return springs are fixed to the outside of the extended square tube.

[0010] In a preferred embodiment, each of the two sealing plates has an inclined surface a at one of its opposite ends, and a contact plate fixed to the top of the movable plate is provided directly below each of the two inclined surfaces a. The top of each contact plate has an inclined surface b that cooperates with the inclined surface a.

[0011] In a preferred embodiment, the top of the movable plate is also fixed to the inner top wall of the melting furnace by two symmetrically arranged support springs.

[0012] In a preferred embodiment, the material quantity adjustment structure includes an adjustment plate located below the moving plate. The adjustment plate slides inside the melting furnace, and its shape matches that of the moving plate. Two symmetrically arranged sliding grooves are provided at the bottom of the moving plate. Each sliding groove is slidably connected to a sliding seat with an inverted convex vertical cross-section. The telescopic ends of electric push rods are fixed to the opposite side walls of the two sliding seats, and the electric push rods are fixed to the bottom of the moving plate.

[0013] In a preferred embodiment, push-pull rods are hinged to the opposite side walls of the two sliding seats, and the bottom ends of the push-pull rods are hinged to the top of the adjusting plate.

[0014] Compared with the prior art, the high-temperature melting treatment device for fly ash provided by this utility model has at least the following beneficial effects:

[0015] In this invention, when using the high-temperature melting fly ash treatment device, fly ash can be conveyed into the melting furnace through the feed pipe and the extended square tube. When the fly ash reaches a certain amount, it will press against the adjusting plate and move upward, thereby causing the moving plate to move upward as well. This compresses the two support springs, and with the setting of inclined planes a and b, the two sealing plates move towards each other and fit together, thereby achieving internal sealing of the extended square tube and realizing quantitative fly ash introduction. This avoids the phenomenon of explosion caused by excessive fly ash introduction. After a batch of quantitative fly ash is processed, the two support springs move the moving plate downward and reset. Furthermore, when it is necessary to change the quantitative fly ash introduction amount, the two electric push rods can be activated to simultaneously push or pull the corresponding sliding seats to move, thereby causing the two sliding seats to move away from each other or towards each other. Combined with the action of the push-pull rod, the distance between the adjusting plate and the moving plate can be adjusted, thus making the quantitative fly ash introduction amount adjustable to meet the needs of different processing situations and greatly improving its applicability.

Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention.

[0023] Example

[0024] Although the above application can achieve quantitative introduction treatment when treating fly ash, avoiding the phenomenon of explosion caused by excessive fly ash introduction during high-temperature melting treatment, the amount of material introduced in this application is fixed. That is to say, the thickness of the moving plate 5 is fixed, and only a fixed amount of fly ash can be poured in intermittently. The thickness of the moving plate 5 cannot be adjusted, which makes it difficult to adjust the amount of fly ash poured in intermittently according to different situations, greatly reducing its applicability.

[0025] For this purpose, please refer to Figure 1-3 This utility model provides a high-temperature melting treatment device for fly ash, including: a melting furnace 1, a feed pipe 2 fixed at the top feed inlet of the melting furnace 1, an extended square pipe 4 fixedly connected to the bottom end of the feed pipe 2, a limiting sleeve 41 fixedly connected to the outside of the extended square pipe 4, and a movable plate 5 movably sleeved on the outside of the extended square pipe 4, the movable plate 5 sliding on the inside of the melting furnace 1.

[0026] It also includes an intermittent sealing structure 3 and a material quantity adjustment structure 6. The intermittent sealing structure 3 is installed on the top of the moving plate 5 and connected to the inner bottom wall of the melting furnace 1 and the extended square tube 4. After the fly ash enters the melting furnace 1, the intermittent sealing structure 3 can push the moving plate 5 to move upward and cause the material to stop in the extended square tube 4.

[0027] The material quantity adjustment structure 6 is installed at the bottom of the movable plate 5 and connected to the extended square tube 4. The material quantity adjustment structure 6 can easily adjust the bottom height of the movable plate 5.

[0028] The outer edge of the movable plate 5 is provided with a sealing ring, and the middle of the movable plate 5 is provided with a square hole that matches the extended square tube 4. The inner wall of the square hole is provided with a sealing ring. The same applies to the adjusting plate 64. For the specific external structure of the melting furnace 1, see the main diagram shown in the high-temperature melting treatment device for fly ash with authorization announcement number CN210586334 U.

[0029] Further as Figure 1-3As shown, it is worth noting that the intermittent sealing structure 3 includes sealing plates 31 that are movably inserted into the outer walls of both sides of the extended square tube 4. The top of each sealing plate 31 is fixed with a return spring 33 through a connecting block 32. The other end of each return spring 33 is fixed to the outside of the extended square tube 4. The opposite ends of the two sealing plates 31 are provided with inclined surfaces a. Directly below each of the two inclined surfaces a, there are contact plates 34 fixed to the top of the moving plate 5. The top of each contact plate 34 is provided with an inclined surface b that cooperates with the inclined surface a. The top of the moving plate 5 is also fixed to the inner top wall of the melting furnace 1 through two symmetrically arranged support springs 35.

[0030] The outer walls on both sides of the extended square tube 4 are provided with channels to facilitate the movement of the sealing plate 31, and sealing rings can be installed in the channels.

[0031] Further as Figure 1-3 As shown, it is worth noting that in order to adjust the amount of fly ash introduced each time, a material quantity adjustment structure 6 is provided, including an adjustment plate 64 located below the moving plate 5. The adjustment plate 64 slides inside the melting furnace 1. The shape of the adjustment plate 64 matches the shape of the moving plate 5. Two symmetrically arranged sliding grooves are opened at the bottom of the moving plate 5. Sliding seats 61 with inverted convex structure in vertical cross section are slidably connected in the sliding grooves. The telescopic ends of electric push rods 62 are fixed to the opposite side walls of the two sliding seats 61. The electric push rods 62 are fixed to the bottom of the moving plate 5. Push-pull rods 63 are hinged to the opposite side walls of the two sliding seats 61. The bottom ends of the push-pull rods 63 are hinged to the top of the adjustment plate 64.

[0032] The shape of the sliding seat 61 makes the movement smoother, and the smaller the distance between the adjusting plate 64 and the moving plate 5, the more fly ash is introduced each time, and vice versa.

[0033] In summary: When using this high-temperature molten fly ash treatment device, fly ash can be conveyed into the melting furnace 1 through the feed pipe 2 and the extended square pipe 4. When the fly ash reaches a certain amount, it will press against the adjusting plate 64 and move upward, thereby causing the moving plate 5 to also move upward. This, in conjunction with the compression of the two support springs 35, and with the setting of inclined planes a and b, the two sealing plates 31 move towards each other and fit together, thereby achieving internal sealing of the extended square pipe 4. This achieves quantitative introduction of fly ash, avoiding the phenomenon of explosion caused by excessive amount of fly ash introduced. After the quantitative fly ash is processed, the two support springs 35 move the moving plate 5 down to reset. Next, when it is necessary to change the amount of fly ash introduced quantitatively, the two electric push rods 62 can be activated to push or pull the corresponding sliding seats 61 to move synchronously, so that the two sliding seats 61 move away from each other or towards each other. Combined with the action of the push-pull rod 63, the distance between the adjusting plate 64 and the moving plate 5 can be adjusted, so that the amount of fly ash introduced quantitatively each time can be adjusted to meet the needs of different processing situations and greatly improve its applicability.
