Description

Technical Field

[0001] This application relates to the field of mortar preparation technology, and more specifically, to a water washing device for preparing mortar using fly ash. Background Technology

[0002] With the acceleration of urbanization and population growth, the amount of municipal solid waste generated is increasing year by year, and incineration has been widely used as an effective waste reduction method. However, fly ash generated during municipal solid waste incineration is classified as hazardous waste due to its content of heavy metals, dioxins, and high concentrations of chloride ions, and must be safely and properly disposed of. Currently, fly ash disposal generally follows the principles of harmlessness, waste reduction, and resource utilization. One promising resource utilization approach is to use treated fly ash to prepare foamed ceramic materials. Components such as calcium oxide, silicon dioxide, and alumina in fly ash can enhance the strength and durability of ceramic products during high-temperature firing, providing a potential raw material source for the production of foamed ceramics.

[0003] Although fly ash has certain application potential in ceramic preparation, its high chloride ion content directly affects the quality of ceramic products, potentially leading to porous structure, reduced strength, and decreased durability. Therefore, in the process of preparing foamed materials using fly ash, the water washing and dechlorination process for mortar preparation is a crucial step. Currently, the common water washing and dechlorination process for mortar preparation involves using clean water or circulating filtrate as washing water, mixing fly ash with the washing liquid in a certain proportion, soaking the mixture, and then stirring to promote the dissolution of chloride ions and heavy metals, thus producing a mortar that meets the requirements.

[0004] However, existing water washing equipment for preparing slurry from fly ash still has significant shortcomings in practical applications. On the one hand, the mixing time between fly ash and water is usually short, resulting in insufficient contact between fly ash and liquid and low chloride ion dissolution efficiency. On the other hand, the mixing method of existing equipment is relatively simple, often relying on conventional stirring devices, such as relying solely on a stirring paddle to stir the fly ash and liquid in a static mixing chamber. This easily leads to dead zones in the stirring, making it difficult to achieve uniform mixing of fly ash and liquid, thus affecting the dechlorination effect during the preparation of slurry. Summary of the Invention

[0005] In view of this, this application provides a water washing device for preparing slurry using fly ash, so as to solve the technical problem of low mixing efficiency of fly ash and liquid in the existing water washing device for preparing slurry using fly ash.

[0006] This application provides a water washing device for preparing slurry using fly ash, wherein the water washing device for preparing slurry using fly ash includes:

[0007] The equipment compartment is provided with an openable and closable partition structure for dividing the interior of the equipment compartment into an upper cavity and a lower cavity;

[0008] The system comprises a first mixing half-compartment, a second mixing half-compartment, a synchronization mechanism, a rotation drive mechanism, and a first telescopic drive mechanism. Both the first and second mixing half-compartments are rotatably mounted within the upper cavity. The first and second mixing half-compartments share the same horizontal axis of rotation. The first mixing half-compartment has a first opening, and the second mixing half-compartment has a second opening. The first and second openings face each other and are aligned. The rotation drive mechanism is connected to the first mixing half-compartment via the synchronization mechanism to enable the second mixing half-compartment to rotate synchronously with the first mixing half-compartment. The first telescopic drive mechanism is connected to the second mixing half-compartment to drive the second mixing half-compartment to move closer to or away from the first mixing half-compartment, such that the end face at the first opening is in contact with or spaced from the end face at the second opening. At least one of the first and second mixing half-compartments has a water seepage hole.

[0009] The equipment chamber is equipped with an inlet pipe, an outlet pipe, a fly ash feed pipe, and a discharge pipe. The inlet pipe leads to the upper chamber, and the outlet pipe and discharge pipe lead to the lower chamber. The fly ash feed pipe extends into the upper chamber and leads to the inside of the first mixing half-chamber.

[0010] Furthermore, the first hybrid semi-compartment includes a first circular end plate and a first side panel surrounding the first circular end plate. The first end of the first side panel is connected to the first circular end plate, and the second end of the first side panel encloses the first opening. The first side panel gradually expands outward from its first end toward its second end. The second hybrid semi-compartment includes a second circular end plate and a second side panel surrounding the second circular end plate. The first end of the second side panel is connected to the second circular end plate, and the second end of the second side panel encloses the second opening. The second side panel gradually expands outward from its first end toward its second end.

[0011] Furthermore, a sleeve is provided on the side of the first circular end plate away from the first side panel. The sleeve passes through the first circular end plate and is rotatably fitted onto the fly ash feed pipe. The sleeve and the fly ash feed pipe are axially limited relative to each other. The rotation drive mechanism includes a motor installed on the outside of the equipment chamber. The output shaft of the motor has a transmission shaft section extending into the upper cavity. A first gear is provided on the transmission shaft section, and a second gear is provided on the sleeve. The first gear meshes with the second gear.

[0012] Furthermore, the end of the fly ash feed pipe passes through the sleeve and extends into the side of the first circular end plate facing the second circular end plate. A first annular platform is formed on the outer side of the end port of the fly ash feed pipe. The first annular platform is in stop-fitting with the side of the first circular end plate facing the second circular end plate. A second annular platform is also provided on the fly ash feed pipe. The second annular platform is in stop-fitting with the end face of the sleeve away from the first circular end plate.

[0013] Furthermore, a sealing cover is provided inside the upper cavity to protect the first gear and the second gear.

[0014] Furthermore, the first telescopic drive mechanism is a first cylinder installed in the equipment compartment, the piston rod of the first cylinder extends into the upper cavity, and the second circular end plate is rotatably fitted on the piston rod of the first cylinder and is axially limited on the piston rod of the first cylinder.

[0015] Furthermore, the synchronization mechanism includes a synchronization rod and a synchronization ear plate. The synchronization ear plate has a through hole and is disposed at the second end of the first side panel. The synchronization rod is connected to the second end of the second side panel and extends through the through hole in the synchronization ear plate along the telescopic movement direction of the first telescopic drive mechanism.

[0016] Furthermore, a stirring rod is connected to the side of the first circular end plate facing the second mixing half-chamber, and the stirring rod is provided with multiple stirring blades.

[0017] Furthermore, the openable and closable partition structure includes a fixed partition, a first movable partition, and a second movable partition. The fixed partition forms a discharge port. A second telescopic drive mechanism and a third telescopic drive mechanism are installed on the equipment chamber. The second telescopic drive mechanism is connected to the first movable partition to drive the first movable partition to move closer to or away from the second movable partition. The third telescopic drive mechanism is connected to the second movable partition to drive the second movable partition to move closer to or away from the first movable partition. The first movable partition and the second movable partition can move closer to each other to close and seal the discharge port, or move away from each other to open the discharge port.

[0018] Furthermore, the equipment chamber is provided with a water outlet and a material outlet at the bottom of the lower cavity, the water outlet is higher than the material outlet, a filter is installed on the inner wall of the equipment chamber at the water outlet, the water outlet pipe extends into the equipment chamber and is connected to the filter, and the material outlet pipe is connected to the material outlet.

[0019] The beneficial effects of the water washing equipment for preparing slurry using fly ash provided by this invention are as follows:

[0020] Compared to existing technologies, the washing equipment for preparing slurry using fly ash provided by this invention has a first and second mixing half-chamber that can rotate synchronously. The end face of the first opening is either in contact with or spaced from the end face of the second opening. Therefore, the first and second mixing half-chambers can fit together to form a closed rotating mixing chamber structure. When water is introduced into the upper chamber when it is separated from the lower chamber, the water can enter the closed rotating mixing chamber structure through the seepage hole. Then, fly ash can be introduced into the rotating mixing chamber structure through the fly ash feed pipe. Activating the rotation drive mechanism can drive the rotating mixing chamber. The rotating mixing chamber structure allows fly ash and water to mix thoroughly for the required time before the first and second mixing half-chambers are separated, releasing the fully mixed fly ash slurry. Compared to the traditional method that relies solely on agitators to stir the fly ash and liquid in a static mixing chamber, all the fly ash rotates along with the entire rotating mixing chamber structure while mixing with water. The fly ash and water are thoroughly and completely agitated during the rotation, greatly improving the mixing time and efficiency, thereby enhancing the dechlorination effect.

[0021] Furthermore, a more significant advantage of this fly ash slurry preparation washing equipment is that the gap between the end faces of the first and second openings can be precisely controlled by the first telescopic drive mechanism. The fly ash slurry mixed in the rotating mixing chamber structure can be thrown out through this gap during rotation. By controlling the length of this gap, the fineness of the fly ash slurry that is thrown out can be ensured through thorough mixing. Continuously rotating the first and second mixing half-chambers with gaps until all the fly ash slurry is thrown out of the rotating mixing chamber structure can prevent large lumps of insufficiently mixed fly ash slurry from flowing out of the rotating mixing chamber structure, further improving the mixing effect of fly ash and water.

[0022] Other beneficial effects of the present invention will be described below. Attached Figure Description

[0039] See Figures 1 to 9 This application provides a water washing device for preparing slurry using fly ash, wherein the water washing device for preparing slurry using fly ash includes:

[0040] The equipment compartment 100 is provided with an openable and closable partition structure that divides the interior of the equipment compartment 100 into an upper cavity 101 and a lower cavity 102, with the lower cavity 102 located below the upper cavity 101.

[0041] The system comprises a first mixing chamber 200, a second mixing chamber 300, a synchronization mechanism, a rotation drive mechanism, and a first telescopic drive mechanism. Both the first and second mixing chambers 200 and 300 are rotatably mounted within the upper cavity 101. The first and second mixing chambers 200 and 300 share the same horizontal axis of rotation. The first mixing chamber 200 has a first opening, and the second mixing chamber 300 has a second opening. The first and second openings face each other and are aligned. The rotation drive mechanism is connected to the first mixing chamber 200 via a transmission mechanism. Next, the second mixing half-compartment 300 is connected to the first mixing half-compartment 200 through a synchronization mechanism so that it can rotate synchronously with the first mixing half-compartment 200. The first telescopic drive mechanism is connected to the second mixing half-compartment 300 so that it can drive the second mixing half-compartment 300 to move closer to or away from the first mixing half-compartment 200, so that the end face (first end face 201) at the first opening is in contact with or spaced from the end face (second end face 301) at the second opening. A seepage hole 1 is formed on at least one of the first mixing half-compartment 200 and the second mixing half-compartment 300.

[0042] The equipment silo 100 is equipped with an inlet pipe 2, an outlet pipe 3, a fly ash feed pipe 4, and a discharge pipe 5. The inlet pipe 2 leads to the upper cavity 101, and the outlet pipe 3 and the discharge pipe 5 lead to the lower cavity 102. The fly ash feed pipe 4 extends into the upper cavity 101 and leads to the inner side of the first mixing half-silo 200. The equipment silo 100 includes a side wall 103, a top cover 104 on the top of the side wall 103, and a discharge hopper 105 at the lower end of the side wall 103. The inlet pipe 2 is installed on the top cover 104, and the outlet pipe 3 and the discharge pipe 5 are installed on the discharge hopper 105. The fly ash feed pipe 4 passes through the side wall 103. The equipment silo 100 is supported by multiple support columns 6.

[0043] Because the washing equipment for preparing slurry using fly ash provided by the present invention has a first mixing half-chamber 200 and a second mixing half-chamber 300 that can rotate synchronously, and the end faces of the first opening and the second opening are either in contact or spaced apart, the first mixing half-chamber 200 and the second mixing half-chamber 300 can fit together to form a closed rotating mixing chamber structure. At this time, when water is introduced when the upper chamber 101 and the lower chamber 102 are separated, the water can enter the closed rotating mixing chamber structure through the seepage hole 1. Then, fly ash can be introduced into the rotating mixing chamber structure through the fly ash feed pipe 4. Activating the rotation drive mechanism can drive the rotation. The mixing chamber rotates, allowing fly ash and water to mix thoroughly for the required time before the first and second mixing chambers 200 and 300 are separated. This releases the fully mixed fly ash slurry. Compared to the traditional method that relies solely on agitators to stir the fly ash and liquid in a static mixing chamber, this method allows all the fly ash to rotate along with the entire mixing chamber while mixing with water. The fly ash and water are thoroughly and completely agitated during the rotation, significantly increasing the mixing time and efficiency, thereby improving the dechlorination effect.

[0044] Furthermore, a more significant advantage of this fly ash slurry preparation washing equipment is that the gap between the end faces of the first and second openings can be precisely controlled by the first telescopic drive mechanism. The fly ash slurry mixed in the rotating mixing chamber structure can be thrown out through this gap during rotation. By controlling the length of this gap, the fineness of the fly ash slurry being thrown out can be ensured. Continuously rotating the first mixing half-chamber 200 and the second mixing half-chamber 300 with the gap until all the fly ash slurry is thrown out of the rotating mixing chamber structure can prevent large lumps of insufficiently mixed fly ash slurry from flowing out of the rotating mixing chamber structure, further improving the mixing effect of fly ash and water.

[0045] According to one embodiment of this application, a first mixing half-compartment 200 includes a first circular end plate 202 and a first side panel 203 surrounding the first circular end plate 202. A first end of the first side panel 203 is connected to the first circular end plate 202, and a second end of the first side panel 203 encloses a first opening. An end face (first end face 201) at the first opening is formed at the second end of the first side panel 203, and the first side panel 203 gradually expands outward from its first end toward its second end. A second mixing half-compartment 300 includes a second circular end plate 302 and a second side panel 303 surrounding the second circular end plate 302. Preferably, the first side panel 203 and the second side panel 303 are... Each plate 303 has multiple seepage holes 1. By controlling the water level entering the upper cavity 101, the amount of water entering the rotating mixing chamber structure from the seepage holes 1 can be controlled. The first end of the second side plate 303 is connected to the second circular end plate 302. The second end of the second side plate 303 encloses a second opening. The end face (second end face 301) at the second opening is formed at the second end of the second side plate 303. The second side plate 303 gradually expands outward from its first end toward its second end. This allows the fly ash slurry in the first mixing half-chamber 200 and the second mixing half-chamber 300 to slide out from the first side plate 203 and the second side plate 303 after the gap exists.

[0046] According to one embodiment of this application, a sleeve 7 is provided on the side of the first circular end plate 202 away from the first side panel 203. The sleeve 7 passes through the first circular end plate 202 and is rotatably fitted onto the fly ash feed pipe 4. The sleeve 7 and the fly ash feed pipe 4 are sealed together, and the sleeve 7 and the fly ash feed pipe 4 are axially limited to each other. The rotation drive mechanism includes a motor 8 installed on the outside of the equipment chamber 100. The output shaft of the motor 8 has a transmission shaft section that extends into the upper cavity 101. A first gear 9 is provided on the transmission shaft section, and a second gear 10 is provided on the sleeve 7. The first gear 9 and the second gear 10 mesh.

[0047] Specifically, the axial limiting of the sleeve 7 and the fly ash feed pipe 4 can be achieved by the end of the fly ash feed pipe 4 passing through the sleeve 7 and extending into the side of the first circular end plate 202 facing the second circular end plate 302. A first annular platform 41 is formed on the outer side of the end port of the fly ash feed pipe 4. The first annular platform 41 is in stop-fitting cooperation with the side of the first circular end plate 202 facing the second circular end plate 302. A second annular platform 42 is also provided on the fly ash feed pipe 4. The second annular platform 42 is in stop-fitting cooperation with the end face of the sleeve 7 away from the first circular end plate 202.

[0048] In addition, a sealing cover is provided in the upper cavity 101 to protect the first gear 9 and the second gear 10. The protective cover is rotatably sealed to the sleeve 7.

[0049] According to one embodiment of this application, the first telescopic drive mechanism is a first cylinder 11 installed in the equipment compartment 100. The piston rod of the first cylinder 11 extends into the upper cavity 101. The second circular end plate 302 is rotatably mounted on the piston rod of the first cylinder 11 and is axially limited on the piston rod of the first cylinder 11. Specifically, the end of the piston rod of the first cylinder 11 has two limiting rings 12 spaced apart along its axial direction. The second circular end plate 302 is rotatably located between the two limiting rings 12 around the piston rod.

[0050] According to a specific embodiment of this application, the synchronization mechanism includes a synchronization rod 13 and a synchronization ear plate 14. The synchronization ear plate 14 has a through hole and is disposed at the second end of the first side panel 203. The synchronization rod 13 is connected to the second end of the second side panel 303 and extends through the through hole in the synchronization ear plate 14 along the telescopic movement direction of the first telescopic drive mechanism. The synchronization rod 13 forms an anti-detachment protrusion 15 on the side of the synchronization ear plate 14 opposite to the second side panel 303.

[0051] According to a preferred embodiment of this application, a stirring rod 16 is connected to the side of the first circular end plate 202 facing the second mixing half-chamber 300. The stirring rod 16 is provided with a plurality of stirring blades 17. The stirring blades 17, in conjunction with the rotating mixing chamber structure, can provide a more thorough mixing assistance to the water and fly ash in the rotating mixing chamber structure.

[0052] According to one embodiment of this application, the openable and closable partition structure includes a fixed partition 18, a first movable partition 19, and a second movable partition 20. The fixed partition 18 forms a discharge port, and specifically, both fixed partitions 18 are inclined downwards toward the discharge port. A second telescopic drive mechanism (e.g., a second cylinder 21) and a third telescopic drive mechanism (e.g., a third cylinder 22) are installed on the equipment chamber 100. The second telescopic drive mechanism is connected to the first movable partition 19 to drive the first movable partition 19 to move closer to or away from the second movable partition 20. The third telescopic drive mechanism is connected to the second movable partition 20 to drive the second movable partition 20 to move closer to or away from the second movable partition 20. The movable partition 20 moves closer to or further away from the first movable partition 19. The first movable partition 19 and the second movable partition 20 can move closer to each other to close and seal the discharge port, or move further away from each other to leave the discharge port open. When the water inlet pipe 2 supplies water to the upper chamber 101, and when the first mixing half chamber 200 and the second mixing half chamber 300 close and disturb the water and fly ash mixture inside, the first movable partition 19 and the second movable partition 20 close the discharge port. When the fully mixed fly ash slurry is released, the first movable partition 19 and the second movable partition 20 move further away from each other so that the fly ash slurry can fall into the lower chamber 102 through the discharge port.

[0053] In addition, the equipment chamber 100 is provided with a water outlet and a material outlet at the bottom of the corresponding lower cavity 102. The water outlet is higher than the material outlet. A filter 23 is installed on the inner wall of the equipment chamber 100 at the water outlet. The water outlet pipe 3 extends into the equipment chamber 100 and connects to the filter 23. The material outlet pipe 5 is connected to the material outlet.

[0054] It should be noted that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting this application. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of this application, such as combining different features in various embodiments, and these should all fall within the protection scope of this application.
