Description

Technical Field

[0001] This invention relates to the field of hazardous waste treatment technology, specifically to a device for solidifying fly ash after hazardous waste incineration. Background Technology

[0002] Fly ash from waste incineration is a fine particulate matter produced during the incineration process. It contains toxic and harmful substances such as heavy metals and dioxins, and improper handling can pose a threat to the environment and human health. Solidification treatment is a key technology that uses physical or chemical methods to fix the harmful substances in fly ash into a stable solid matrix, thereby reducing their mobility and toxicity.

[0003] Currently, the most widely used method for fly ash treatment in the industry is to add cement and water to the fly ash in a certain proportion, mix them to make concrete, then pour the mixed concrete into a curing mold, wait for it to solidify to form concrete blocks, and finally carry out landfill treatment.

[0004] However, this processing technology has significant drawbacks. The secondary transfer process, from the mixing equipment to the curing mold, requires the use of conveyor equipment or manual handling, making the operation cumbersome. This not only increases equipment and labor costs but also prolongs the transfer process, resulting in low overall processing efficiency and failing to meet the needs of large-scale hazardous waste fly ash treatment. Therefore, there is an urgent need to design a hazardous waste incineration fly ash curing device that simplifies the processing procedure and improves efficiency. To this end, we propose a hazardous waste incineration fly ash curing device to effectively address the aforementioned shortcomings. Summary of the Invention

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 7 A device for solidifying fly ash after hazardous waste incineration includes a mixing hopper 100. The mixing hopper 100 has an internal mixing mechanism 200, which includes a stirrer 201 rotatably mounted inside the mixing hopper 100. An external drive motor 202 is also provided on the outside of the mixing hopper 100, with the output shaft of the drive motor 202 coaxially connected to the stirrer 201. Additionally, a cover plate is provided on the top of the mixing hopper 100, which can be closed during the mixing process to prevent fly ash from overflowing.

[0038] It should be noted that the function of the mixing bucket 100 is to contain the fly ash after incineration, and at the same time add an appropriate amount of water and cement to the fly ash. With the action of the mixing mechanism 200, the fly ash can be made into a concrete-like material.

[0039] This embodiment also includes a curing tank 300, a curing section 400, and a three-axis moving mechanism 500. The curing tank 300 is located below the mixing hopper 100. The curing tank 300 has a rectangular hollow, open-top structure. The curing tank 300 and the mixing hopper 100 are fixedly connected by a column. The curing tank 300 is made of metal, such as stainless steel. The length of the curing tank 300 is greater than the length of the mixing hopper 100, and the upper and lower ends of the column are welded and fixed to the mixing hopper 100 and the curing tank 300, respectively.

[0040] In addition, the curing section 400 is a rectangular block shape made of aluminum alloy. Both ends of the curing section 400 have a hollow design to reduce overall weight and facilitate handling. The curing section 400 is detachably installed inside the curing tank 300. Several mounting cavities are formed on the top surface of the curing section 400, each containing a curing chamber 600 for holding materials. The length and width of the curing section 400 are adapted to the internal length and width of the curing tank 300, therefore, the curing section 400 can be directly placed inside the curing tank 300. The top surface of the curing section 400 is lower than the top surface of the curing tank 300, and handles 401 are symmetrically provided on both sides of the top surface of the curing section 400; their function is to facilitate handling by workers.

[0041] It should be added that the mounting cavities are arranged in a matrix. Specifically, in this embodiment, there are three columns of mounting cavities, and each column contains several mounting cavities. The curing chamber 600 is detachably connected to the mounting cavity. The top surface of the curing chamber 600 has an opening for accommodating the stirred material.

[0042] Furthermore, a three-axis moving mechanism 500 is located on the top surface of the curing tank 300, and a discharging mechanism 700 is provided at the execution end of the three-axis moving mechanism 500. The three-axis moving mechanism 500 is used to control the discharging mechanism 700 to move along the X, Y, and Z axes, so that the discharging mechanism 700 is aligned with several curing chambers 600 respectively. The bottom of the mixing hopper 100 is provided with a discharge port 101, and a discharging hose 102 is provided between the discharge port 101 and the discharging mechanism 700. In addition, an electric discharging valve is provided at the discharge port 101, and the discharging hose 102 is made of rubber. When the electric discharging valve is opened, the internal material can enter the discharging mechanism 700 through the discharging hose 102, and finally be discharged into the curing chamber 600 by the discharging mechanism 700.

[0043] In addition, to facilitate material discharge, in some embodiments of this application, a vibration motor may be provided on the outside of the mixing bucket 100. The vibration motor drives the mixing bucket 100 to vibrate, so that the material inside can be discharged more easily and thoroughly from the discharge port 101.

[0044] The structure of the curing chamber 600 is described in detail below:

[0045] The curing chamber 600 includes an outer frame 601 and an inner tank 602. The outer frame 601 is a hollow rectangular structure that runs vertically through the interior. The inner tank 602 is movably disposed inside the outer frame 601. The inner tank 602 has first movable columns 603 on both the front and rear sides of its top, and second movable columns 604 on both the front and rear sides of its bottom. The outer frame 601 has first movable slots 605 on both its front and rear sides of its top, and second movable slots 606 on both its front and rear sides of its bottom. The first movable columns 603 extend into the corresponding first movable slots 605, and the second movable columns 604 extend into the corresponding second movable slots 606. The first movable columns 603 and second movable columns 604 can move left and right within the first movable slots 605 and second movable slots 606, respectively, and both are detachably connected to the inner tank 602 by bolts.

[0046] Furthermore, the first movable groove 605 has first elastic plates 607 on both its left and right sides, and one end of each of the two first elastic plates 607 is connected to the first movable column 603; the second movable groove 606 has second elastic plates 608 on both its left and right sides, and one end of each of the two second elastic plates 608 is connected to the second movable column 604; as... Figure 3 As shown, the first movable column 603 is elastically connected in the first movable groove 605, and the second movable column 604 is elastically connected in the second movable groove 606; and the first elastic plate 607 and the second elastic plate 608 are both arc-shaped spring plates. In the natural state, the first movable column 603 and the second movable column 604 are both in the center position, and the inner pool 602 maintains a vertical posture.

[0047] It is worth mentioning that the first movable groove 605 is an upwardly raised arc shape, and the second movable groove 606 is a downwardly concave arc shape, and the first movable groove 605 and the second movable groove 606 are symmetrically distributed vertically; specifically, when the first movable column 603 remains stationary in the center position, the second movable column 604 can swing left and right around the second movable groove 606; conversely, when the second movable column 604 remains stationary in the center position, the first movable column 603 can swing left and right around the first movable groove 605.

[0048] In some embodiments of this application, the curing chamber 600 further includes a vibration assembly for causing the inner tank 602 to vibrate. Specifically, the vibration assembly includes a first electromagnet 609 and a second electromagnet 610, which attract the inner tank 602. The first electromagnet 609 and the second electromagnet 610 are symmetrically distributed and fixed to the inner wall of the outer frame 601. The inner tank 602 is made of ferrous material and can be attracted by the electromagnets. When the first electromagnet 609 is energized, the upper end of the inner tank 602 can tilt towards the side of the first electromagnet 609, such as... Figure 7As shown; when the second electromagnet 610 is energized, the lower end of the inner tank 602 can tilt towards the side of the second electromagnet 610, as shown. Figure 6 As shown.

[0049] In addition, the vibration assembly also includes two first conductive plates 611 and two second conductive plates 612. The two first conductive plates 611 are respectively fixedly embedded on the front and rear sides of the top surface of the outer frame 601, and are respectively connected to the two leads of the first electromagnet 609. The two second conductive plates 612 are respectively fixedly embedded on the front and rear sides of the top surface of the outer frame 601, and are respectively connected to the two leads of the second electromagnet 610. Both the first conductive plates 611 and the second conductive plates 612 are made of thin copper sheets, and are insulated from each other, for example, by laying an insulating layer on the bottom surface of the two conductive plates to prevent conductivity between the conductive plates and the inner pool 602.

[0050] The structure of the feeding mechanism 700 is described in detail below:

[0051] The feeding mechanism 700 includes an outer shell 701, a feeding hopper 702, and a feeding pipe 703. The outer shell 701 is fixedly connected to the execution end of the three-axis moving mechanism 500. The feeding hopper 702 is fixedly disposed inside the outer shell 701 and has a through-hole structure. The feeding pipe 703 is movably inserted into the feeding hopper 702, and the bottom end of the feeding pipe 703 extends out of the feeding hopper 702. Specifically, the feeding hopper 702 and the outer shell 701 are welded and fixed together, and the feeding hopper 702 has a shape that is wider at the top and narrower at the bottom. The feeding pipe 703 is a square tube structure that is through-hole at both ends. The bottom end of the feeding pipe 703 is provided with a discharge gate 704. The outer surface of the feeding pipe 703 and the inner surface of the feeding hopper 702 are tightly fitted to prevent material from entering the gap between the feeding pipe 703 and the feeding hopper 702.

[0052] It should be added that the outer wall of the discharge pipe 703 and the inner wall of the discharge hopper 702 are both chrome-plated. The chrome plating is used to improve their surface smoothness and wear resistance. The discharge gate 704 is a double gate, which includes two gate plates and two electric actuators. The electric actuators are used to control the relative movement of the two gates to open and close the bottom of the discharge pipe 703.

[0053] Furthermore, a DC power supply 705 is provided inside the outer casing 701, and conductive posts 706 are provided on both the front and rear sides of the bottom of the outer casing 701. The two conductive posts 706 are respectively connected to the positive and negative terminals of the DC power supply 705. A vertically distributed linear module 707 is provided on one side of the interior of the outer casing 701. The movable end of the linear module 707 is fixedly connected to the feeding tube 703 through a connecting rod 708. The linear module 707 can be a linear slide. It should be noted that when the feeding tube 703 is retracted upward to its maximum extent, the bottom end of the feeding tube 703 is higher than the bottom surface of the outer casing 701.

[0054] It is worth mentioning that the spacing between the two conductive posts 706 is adapted to the width of the outer frame 601. That is, when the two conductive posts 706 slide along the front and rear side walls of the top of the outer frame 601, the conductive posts 706 can successively abut against the two conductive sheets.

[0055] In summary, in the specific application of this embodiment, fly ash, cement (other curing agents can also be used to replace cement), and water are poured into the mixing hopper 100 in a certain proportion, the cover plate is closed, and the mixing mechanism 200 is started. After mixing for a period of time, concrete-like material can be formed. Then, the electric discharge valve is opened, so that the material passes through the discharge port 101, the discharge hose 102 and then enters the discharge pipe 703.

[0056] In the initial state, the discharge gate 704 at the bottom of the discharge pipe 703 is closed, and the discharge mechanism 700 is positioned on one side of one of the solidification chambers 600 via the three-axis moving mechanism 500, with the two conductive pillars 706 abutting against the top front and rear sides of the outer frame 601; then, the linear module 707 controls the discharge pipe 703 to extend into the inner tank 602, and slowly controls the discharge mechanism 700 to move along the length of the solidification section 400. Figure 6 As shown, the feeding mechanism 700 moves forward while unloading material until the two conductive posts 706 and the two second conductive plates 612 come into contact. At this point, the second electromagnet 610 is energized, causing the inner tank 602 to tilt towards the direction closest to the second electromagnet 610. When the conductive posts 706 and the second conductive plates 612 separate, the bottom of the inner tank 602 will shake under the resetting action of the elastic plate, which helps to make the material at the bottom of the inner tank 602 shake evenly and compactly.

[0057] As the feeding mechanism 700 continues to move, the feeding tube 703 simultaneously contracts upwards until the conductive column 706 passes the two first conductive plates 611. At this point, the top of the inner tank 602 will shake. Figure 7 As shown, this shakes and compacts the material at the top of the inner tank 602.

[0058] After the two conductive posts 706 pass the first conductive sheet 611, the discharge gate 704 closes, and the discharge pipe 703 retracts upward to its maximum extent. As the discharge mechanism 700 continues to move, when the discharge pipe 703 enters above the next inner tank 602, the discharge pipe 703 re-enters the inner tank 602, and the discharge gate 704 opens simultaneously, repeating this process. Until the discharge mechanism 700 moves from one side of a row of curing chambers 600 to the other, the three-axis moving mechanism 500 controls the discharge mechanism 700 to move to the next row of curing chambers 600.

[0059] It is worth mentioning that, in this embodiment, when the discharge pipe 703 discharges material into the inner tank 602, the discharge pipe 703 is in a continuous translational and upward motion, meaning that the discharge position is constantly changing. This helps to ensure that the material evenly fills the inner tank 602. Simultaneously, when the bottom of the inner tank 602 is full of material, the bottom of the inner tank 602 will shake under the action of the second electromagnet 610, which helps to evenly distribute the material and avoid gaps. When the top of the inner tank 602 is full of material, the top of the inner tank 602 will shake under the action of the first electromagnet 609, further preventing gaps and ensuring that the amount of material in each curing chamber 600 remains consistent.

[0060] Once all the curing chambers 600 are full of material, the workers can remove the curing unit 400 and place it into another unused curing unit 400 to continue unloading until all the material in the mixing hopper 100 is drained.

[0061] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
