Description

TECHNICAL FIELD

[0001] The utility model relates to solid waste ash treatment field, specifically is a kind of solid waste ash vitrification treatment device. BACKGROUND

[0002] With the acceleration of industrialization, various solid wastes, fly ash of coal-fired power plants, metallurgical slag, hazardous waste and so on are increasing rapidly, and the traditional treatment methods of landfill and incineration have high heavy metal leaching risk and serious secondary pollution problems, so glassification treatment technology is an important direction to solve the problem of complex solid waste treatment by converting solid waste into stable glassy material through high-temperature melting, effectively solidifying heavy metal ions and greatly reducing volume.

[0003] The solid waste treatment method reduces the leaching risk of heavy metals in solid waste ash, and after glassification treatment, heavy metals are firmly imprisoned in the glass structure, reducing pollution to soil and water sources, and the glassy product after treatment can be recycled as building materials, road fillers and the like, realizing the change from waste to resource.

[0004] Before the glassification treatment of solid waste ash, the size of solid waste ash is different, which is difficult to handle, and cannot be uniformly melted and glassified, therefore, a solid waste ash glassification treatment device is proposed to solve the above problems. INVENTION CONTENTS

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0006] The technical scheme adopted by the utility model to solve its technical problems is: the utility model discloses a kind of solid waste ash glassification treatment device, including container;The first support is fixedly connected to the side wall of the container;The first support top is provided with feed inlet;The heating plate is fixedly connected in the container interior;The first support top is fixedly connected with the coaming, and the first support bottom is fixedly connected with a pair of hydraulic rod;The hydraulic rod bottom is fixedly connected with fixed seat;The first pressure head is fixedly connected to the fixed seat bottom;The second pressure head is fixedly connected to the first pressure head bottom;The first support side wall is fixedly connected with water tank;The water tank top is fixedly connected with water outlet pipe;The first support side wall is rotatably connected with conveying shaft;The first support side wall is fixedly connected with bottom plate;Through the above structure, the solid waste ash particles after crushing are smaller, can be more evenly distributed in the heating equipment, reduce the situation that part of solid waste ash is too large and not melted, so that the contact area with heating plate medium is greatly increased, and the glass body structure formed by rapid cooling is convenient for further purification and recovery of different components therein.

[0007] Preferably, a motor is fixedly connected to the side wall of the first support; a rotating shaft is fixedly connected to the output end of the motor; multiple sets of rotating blades are fixedly connected to the side wall of the rotating shaft; the rotating blades cause the ash and slag to move forward continuously, reducing the occurrence of blockage, allowing the ash and slag to enter the second pressure head more evenly, improving the crushing effect and efficiency, and making the ash and slag particles more uniform in size to prepare for subsequent processing.

[0008] Preferably, a second support is fixedly connected to the top of the first support; an electric actuator is fixedly connected to the side wall of the second support; and a baffle is fixedly connected to the end of the electric actuator. For smaller solid waste ash residues, the size of the feed inlet can be appropriately adjusted via the baffle. This ensures smooth feeding while controlling the speed and flow rate of the ash residue entering the container, allowing subsequent crushing, heating, and other processing steps to be more efficiently matched. The feed inlet size can be flexibly adjusted according to the actual size and shape of the solid waste ash residues to ensure that ash residues of different specifications can smoothly enter the processing equipment, avoiding blockage problems caused by an excessively small feed inlet.

[0009] Preferably, heating rods are fixedly connected to the side wall of the enclosure; multiple heating rods are provided and arranged in an array on the enclosure; by using multiple sets of heating rods, the melting point and smelting temperature requirements of different types of solid waste ash are different, which can save the power and number of heating rods in each set, control the smelting temperature, meet the smelting requirements of specific solid waste ash above the heating plate, and ensure the best smelting effect.

[0010] Preferably, a protective cover is fixed to the side wall of the first support; the protective cover is correspondingly arranged with the first support; the protective cover reduces the splashing of ash and slag into the surrounding environment, reducing safety hazards such as slipping and tripping caused by the scattering of ash and slag. While blocking the splashing of ash and slag, the protective cover can also effectively inhibit the spread of solid waste ash and slag dust. Reducing the splashing of ash and slag will cause dust to be raised and spread to a wider area. The protective cover can control the dust within a certain range.

[0011] Preferably, a hot air blower is fixed to the side wall of the protective cover; the side wall of the hot air blower has multiple sets of strip holes; the hot air blower can accelerate the removal of moisture from the ash slag, so that the moisture content of the ash slag is reduced when it enters the heating plate stage, thereby reducing the heat and time consumption for evaporating moisture during the smelting process, accelerating the smelting speed and the amount of smelting.

[0012] The advantages of this utility model are:

[0013] 1. The solid waste ash vitrification treatment device of this utility model reduces the size of the solid waste ash particles after crushing by the second pressure head, making them more regular and uniform in size. This allows for more even distribution in the heating equipment, ensuring that heat is fully transferred to each particle and reducing the occurrence of some large, unmelted solid waste ash particles. This improves the overall processing efficiency, significantly increases the contact area with the heating plate medium, and allows for faster heat absorption, shortening the overall heating time and improving processing efficiency. The glassy structure formed by the rapid cooling of the solid waste ash through the water outlet pipe facilitates further purification and recovery of its different components.

[0014] 2. The solid waste ash vitrification treatment device of this utility model can appropriately adjust the size of the feed inlet for smaller solid waste ash by means of a baffle. While ensuring smooth feeding, it controls the speed and flow rate of ash entering the container, so that subsequent crushing, heating and other processing steps can be matched more efficiently. The feed inlet size can be flexibly adjusted according to the actual size and shape of the solid waste ash to ensure that ash of different specifications can enter the processing equipment smoothly and avoid the blockage problem caused by the feed inlet being too small.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a solid waste ash vitrification treatment device includes a container 1; a first support 11 is fixedly connected to the side wall of the container 1; a feed inlet 12 is opened at the top of the first support 11; a heating plate 13 is fixedly connected inside the container 1; a surrounding plate 14 is fixedly connected to the top of the container 1; a pair of hydraulic rods 15 are fixedly connected to the bottom of the first support 11; a fixed seat 16 is fixedly connected to the bottom of the hydraulic rods 15; a first pressure head 17 is fixedly connected to the bottom of the fixed seat 16; a second pressure head 17 is fixedly connected to the bottom of the first pressure head 17. Head 18; a water tank 19 is fixedly connected to the side wall of the first support 11; a water outlet pipe 110 is fixedly connected to the top of the water tank 19; a conveying shaft 111 is rotatably connected to the side wall of the first support 11; a base plate 112 is fixedly connected to the side wall of the first support 11; during operation, solid waste ash enters from the feed inlet 12 above the base plate 112, the conveying shaft 111 is rotated to move the solid waste ash to below the second pressure head 18, the hydraulic rod 15 applies a thrust to drive the fixed seat 16 to fall, and the solid waste ash remaining below the first pressure head 17 is squeezed, thus compressing the solid waste. The ash residue is crushed, and the conveyor shaft 111 continues to rotate, carrying the solid waste ash residue on the surface of the bottom plate 112 to below the first pressure head 17. The movement of a large amount of solid waste ash residue pushes the crushed residue into the heating plate 13. The heating plate 13 heats the uniformly sized solid waste ash residue that has fallen onto the surface. After heating, the water tank 19 is activated, and liquid is sprayed from the outlet pipe 110 to rapidly cool the solid waste ash residue. Larger pieces of solid waste ash residue may not be heated evenly in the heating equipment, resulting in some areas being difficult to heat. This is addressed by the second pressure head 18. The crushed solid waste ash particles are smaller, making them more regular and uniform in size. This allows for more even distribution in the heating equipment, ensuring that heat is fully transferred to each particle and reducing the occurrence of unmelted, oversized solid waste ash particles. This improves overall processing efficiency and significantly increases the contact area with the heating plate 13, enabling faster heat absorption, shortening the overall heating time, and further improving processing efficiency. The glassy structure formed by the rapid cooling of the solid waste ash through the water outlet pipe 110 facilitates further purification and recycling of its different components.

[0025] like Figure 2As shown, a motor 22 is fixedly connected to the side wall of the first support 11; a rotating shaft 2 is fixedly connected to the output end of the motor 22; multiple sets of rotating blades 21 are fixedly connected to the side wall of the rotating shaft 2; during operation, solid waste ash entering from the feed inlet 12 will accumulate on the surface of the bottom plate 112. When the motor 22 is started, it drives the rotating shaft 2 to rotate. The rotating blades 21 at the end of the rotating shaft 2 will push the solid waste ash that is stuck on the surface of the bottom plate 112 forward. If a large amount of solid waste ash accumulates, it is easy to form a blockage at the feed inlet 12 of the processing equipment. Some ash may not be fully crushed, affecting the smooth progress of the entire processing process. By rotating the blades 21 to make the ash move forward continuously, the occurrence of blockage is reduced, and the ash can enter the second pressure head 18 more evenly, improving the crushing effect and efficiency, and making the ash particle size more uniform to prepare for subsequent processing.

[0026] like Figure 2 As shown, a second support 3 is fixedly connected to the top of the first support 11; an electric push rod 31 is fixedly connected to the side wall of the second support 3; a baffle 32 is fixedly connected to the end of the electric push rod 31; during operation, pushing the electric push rod 31 can drive the baffle 32 to move forward. When the solid waste ash is large, the electric push rod 31 can be retracted to adjust the size of the feed inlet 12. For smaller solid waste ash, the size of the feed inlet 12 can be appropriately adjusted through the baffle 32. While ensuring smooth feeding, the speed and flow rate of the ash entering the container 1 can be controlled, so that subsequent crushing, heating and other processing processes can be matched more efficiently. The size of the feed inlet 12 can be flexibly adjusted according to the actual size and shape of the solid waste ash to ensure that ash of different specifications can enter the processing equipment smoothly and avoid blockage caused by the feed inlet 12 being too small.

[0027] like Figure 4 As shown, heating rods 4 are fixed to the side wall of the enclosure 14; multiple heating rods 4 are provided and arranged in an array on the enclosure 14; during operation, the crushed solid waste ash falls onto the surface of the heating plate 13, and the heating plate 13 is heated and melted. Activating the heating rods 4 can increase the melting effect of the solid waste ash above the heating plate 13. By using multiple sets of heating rods 4, the melting point and the temperature conditions required for melting of different types of solid waste ash are different. The power and number of heating rods 4 in each set can be reduced, and the melting temperature can be controlled to meet the melting requirements of specific solid waste ash above the heating plate 13, ensuring the best melting effect.

[0028] like Figure 2 and Figure 5As shown, a protective cover 5 is fixedly connected to the side wall of the first support 11; the protective cover 5 is correspondingly arranged with the first support 11; during operation, the strong pressure of the second pressure head 18 during the crushing of solid waste ash will cause solid waste ash to splash and pop out. The protective cover 5 can block the splashing of solid waste ash during crushing, thereby reducing the amount of ash splashed into the surrounding environment and reducing safety hazards such as slipping and tripping caused by the ash scattering. While blocking the splashing of ash, the protective cover 5 can also effectively inhibit the diffusion of solid waste ash dust. Reducing the splashing of ash will cause dust to rise and spread to a wider area. The protective cover 5 can control the dust within a certain range.

[0029] like Figure 5 As shown, a hot air blower 6 is fixedly connected to the side wall of the protective cover 5; the side wall of the hot air blower 6 has multiple sets of strip holes 61; during operation, when the solid waste ash enters from the feed inlet 12, there will be moisture on the surface. When the hot air blower 6 is started, the hot air emitted from the strip holes 61 can dry the solid waste ash above the bottom plate 112. The dried moisture gas is blown out from above the feed inlet 12, which increases the melting speed of the solid waste ash that falls into the heating plate 13. The hot air blower 6 can quickly remove the moisture in the ash, so that the moisture content of the ash is reduced when it enters the heating plate 13 stage, thereby reducing the heat and time consumption for evaporating moisture during the melting process, accelerating the melting speed and the melting volume.

[0030] Working principle: Solid waste ash enters from the feed inlet 12 above the bottom plate 112. The rotating conveyor shaft 111 moves the solid waste ash to below the second pressure head 18. The hydraulic rod 15 applies thrust, causing the fixed seat 16 to fall, squeezing and crushing the solid waste ash remaining below the first pressure head 17. The conveyor shaft 111 continues to rotate, moving the solid waste ash on the surface of the bottom plate 112 further to below the first pressure head 17. The movement of a large amount of solid waste ash pushes the crushed solid waste ash into the heating plate 13. The heating plate 13 heats the uniformly sized solid waste ash that has fallen onto the surface. After heating, the water tank 19 is activated, spraying liquid from the outlet pipe 110 to rapidly cool the solid waste ash. The solid waste ash entering from the feed inlet 12 accumulates on the surface of the bottom plate 112. The motor 22 is then started, driving the rotating shaft 2 to rotate. The rotating blade 21 at the end of shaft 2 pushes the solid waste ash residue remaining on the surface of the bottom plate 112 forward. Pushing the electric push rod 31 can drive the baffle 32 to move forward. When the solid waste ash residue is large, the electric push rod 31 can be retracted to adjust the size of the feed inlet 12. After crushing, the solid waste ash residue falls onto the surface of the heating plate 13, where it is heated and melted. Starting the heating rod 4 can increase the melting effect of the solid waste ash residue above the heating plate 13. During the crushing process, the strong pressure of the second pressure head 18 will cause the solid waste ash residue to splash and jump out. The protective cover 5 can prevent the solid waste ash residue from splashing during crushing. When the solid waste ash residue enters from the feed inlet 12, there will be moisture on the surface. Starting the hot air blower 6 and the hot air emitted from the strip hole 61 can dry the solid waste ash residue above the bottom plate 112. The dried humid gas is blown out from above the feed inlet 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
