Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste treatment, and particularly to a fly ash solidification device after incineration of hazardous waste. Background Art

[0002] Fly ash from waste incineration is fine particulate matter generated during the waste incineration process, containing toxic and harmful substances such as heavy metals and dioxins. If not properly treated, it will pose a threat to the environment and human health. Solidification treatment is a key technology to fix the harmful substances in fly ash in a stable solid matrix through physical or chemical methods, reducing its mobility and toxicity.

[0003] Currently, the widely adopted fly ash treatment method in the industry is to add cement and water to fly ash in a certain proportion, make concrete by stirring, then pour the stirred concrete into a solidification mold, wait for it to solidify into concrete blocks, and finally conduct landfill treatment.

[0004] However, this treatment process has obvious defects. During the secondary transfer process of transferring the stirred concrete from the stirring equipment to the solidification mold, it is necessary to rely on conveying equipment or manual handling, and the operation process is cumbersome. This not only increases equipment investment and labor costs, but also the transfer process takes a long time, resulting in low overall treatment efficiency and being difficult to meet the needs of large-scale hazardous waste fly ash treatment. Therefore, there is an urgent need to design a fly ash solidification device after incineration of hazardous waste that can simplify the treatment process and improve the treatment efficiency. For this reason, we have proposed a fly ash solidification device after incineration of hazardous waste to well solve the above drawbacks. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 - Figure 7 , a device for solidifying fly ash after incineration of hazardous waste, including a mixing hopper 100. A mixing mechanism 200 is provided inside the mixing hopper 100. The mixing mechanism 200 includes a mixer 201. The mixer 201 is rotatably arranged inside the mixing hopper 100. A driving motor 202 is also provided outside the mixing hopper 100. The output shaft of the driving motor 202 is coaxially connected to the mixer 201. In addition, a cover plate is provided at the top of the mixing hopper 100. Specifically, during the mixing process, the cover plate can be covered to prevent fly ash from overflowing.

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

[0039] This embodiment further includes a curing tank 300, a curing part 400, and a three-axis moving mechanism 500. Among them, the curing tank 300 is arranged below the mixing hopper 100. The curing tank 300 has a cuboid hollow and lidless structure. The curing tank 300 and the mixing hopper 100 are fixedly connected by columns. The curing tank 300 is made of a metal material, 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 columns are respectively welded and fixed to the mixing hopper 100 and the curing tank 300.

[0040] In addition, the curing part 400 is a cuboid block. The curing part 400 is made of aluminum alloy. Both ends of the curing part 400 also have a hollow design to reduce the overall mass and facilitate handling. The curing part 400 is detachably arranged inside the curing tank 300. A plurality of installation cavities are provided on the top surface of the curing part 400. A curing bin 600 for accommodating materials is arranged in each of the plurality of installation cavities. The length and width of the curing part 400 are adapted to the internal length and width of the curing tank 300. Therefore, the curing part 400 can be directly placed into the curing tank 300. The top surface of the curing part 400 is lower than the top surface of the curing tank 300. Handles 401 are symmetrically arranged on both sides of the top surface of the curing part 400. The function is to facilitate the staff to hold the handles 401 for handling.

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

[0042] Furthermore, the three-axis moving mechanism 500 is arranged on the top surface of the curing tank 300. 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 aligns with a plurality of curing bins 600 respectively. Among them, a discharging port 101 is provided at the bottom of the mixing hopper 100. A discharging hose 102 is arranged between the discharging port 101 and the discharging mechanism 700. In addition, an electric discharging valve is also provided at the discharging port 101. The discharging hose 102 is made of rubber material. When the electric discharging valve is opened, the internal materials can enter the discharging mechanism 700 through the discharging hose 102 and finally be discharged into the curing bin 600 by the discharging mechanism 700.

[0043] In addition, in order to facilitate discharging, in some embodiments of the present application, a vibration motor can also be arranged outside the mixing hopper 100 to drive the mixing hopper 100 to vibrate through the vibration motor, so that the internal materials can be discharged from the discharging port 101 more easily and thoroughly.

[0044] The following is a detailed description of the structure of the curing bin 600:

[0045] The curing bin 600 includes an outer frame 601 and an inner tank 602. The outer frame 601 is a rectangular hollow structure that penetrates up and down. The inner tank 602 is movably arranged inside the outer frame 601. On both the front and rear sides of the top of the inner tank 602, there are first movable columns 603. On both the front and rear sides of the bottom of the inner tank 602, there are second movable columns 604. On both the front and rear side walls of the top of the outer frame 601, there are first movable slots 605. On both the front and rear side walls of the bottom of the outer frame 601, there are second movable slots 606. 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 the second movable columns 604 can move left and right in the first movable slots 605 and the second movable slots 606 respectively, and both the first movable columns 603 and the second movable columns 604 are detachably connected to the inner tank 602 by bolts.

[0046] Further, on both the left and right sides inside the first movable slot 605, there are first elastic pieces 607. One end of each of the two first elastic pieces 607 is connected to the first movable column 603; on both the left and right sides inside the second movable slot 606, there are second elastic pieces 608. One end of each of the two second elastic pieces 608 is connected to the second movable column 604; as Figure 3 shown, the first movable column 603 is elastically connected in the first movable slot 605, and the second movable column 604 is elastically connected in the second movable slot 606; and, both the first elastic pieces 607 and the second elastic pieces 608 are arc-shaped spring pieces. In the natural state, both the first movable column 603 and the second movable column 604 are in the centered position, and the inner tank 602 maintains a vertical posture.

[0047] It is worth mentioning that the first movable slot 605 is in an upwardly convex arc shape, the second movable slot 606 is in a downwardly concave arc shape, and the first movable slot 605 and the second movable slot 606 are symmetrically distributed up and down; specifically, when the first movable column 603 remains in the centered position and does not move, the second movable column 604 can swing left and right around the second movable slot 606; conversely, when the second movable column 604 remains in the centered position and does not move, the first movable column 603 can swing left and right around the first movable slot 605.

[0048] In some embodiments of the present application, the curing bin 600 further includes a vibration assembly for vibrating the inner tank 602. Specifically, the vibration assembly includes a first electromagnet 609 and a second electromagnet 610 for attracting the inner tank 602. The first electromagnet 609 and the second electromagnet 610 are symmetrically distributed up and down and fixedly embedded in the inner wall of the outer frame 601; the inner tank 602 is made of iron material and can be adsorbed by the electromagnet. 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, as Figure 7As shown; when the second electromagnet 610 is energized, the lower end of the inner cell body 602 can tilt towards the side of the second electromagnet 610, as Figure 6 shown.

[0049] In addition, the vibration assembly further includes two first conductive sheets 611 and two second conductive sheets 612. The two first conductive sheets 611 are respectively embedded in the front and rear sides of the top surface of the outer frame 601, and the two first conductive sheets 611 are respectively connected to the two leads of the first electromagnet 609. The two second conductive sheets 612 are respectively embedded in the front and rear sides of the top surface of the outer frame 601, and the two second conductive sheets 612 are respectively connected to the two leads of the second electromagnet 610. The first conductive sheet 611 and the second conductive sheet 612 are both made of copper sheets, and insulation treatment is performed between the first conductive sheet 611 and the second conductive sheet 612. For example, an insulating layer is laid on the bottom surfaces of the two conductive sheets to prevent conduction between the conductive sheets and the inner cell body 602.

[0050] The structure of the feeding mechanism 700 will be described in detail as follows:

[0051] The feeding mechanism 700 includes a housing 701, a feeding hopper 702 and a feeding pipe 703. Among them, the housing 701 is fixedly connected to the execution end of the three-axis moving mechanism 500. The feeding hopper 702 is fixedly arranged inside the housing 701, and the feeding hopper 702 has a structure that is through from top to bottom. 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 is fixedly welded to the housing 701, 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 pipe structure with both ends through. The bottom end of the feeding pipe 703 is provided with a discharge gate 704. The outer surface of the feeding pipe 703 is closely attached to the inner surface of the feeding hopper 702, and its function is to prevent materials from entering the gap between the feeding pipe 703 and the feeding hopper 702.

[0052] It should be added that both the outer wall of the feeding pipe 703 and the inner wall of the feeding hopper 702 have chromium plating layers, and the chromium plating layers are used to improve their surface smoothness and at the same time improve wear resistance. The discharge gate 704 is a double-opening gate. The discharge gate includes two gate plates and two electric actuators. The electric actuators are used to control the relative movement of the two gates to realize the opening and closing of the bottom of the feeding pipe 703.

[0053] Further, a DC power supply 705 is provided inside the outer housing 701. Conductive posts 706 are provided on both the front and rear sides of the bottom of the outer housing 701, and the two conductive posts 706 are respectively connected to the positive and negative electrodes of the DC power supply 705. A linear module 707 distributed vertically is provided on one side inside the outer housing 701. The movable end of the linear module 707 is fixedly connected to the discharge pipe 703 through a connecting rod 708. The linear module 707 can adopt a linear slide. It should be noted that when the discharge pipe 703 contracts upward to the maximum limit, the bottom end of the discharge pipe 703 is higher than the bottom surface of the outer housing 701.

[0054] It is worth mentioning that the distance 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 contact the two conductive sheets.

[0055] In summary, in the specific application process of this embodiment, fly ash, cement (other curing agents can also replace cement), and water are poured into the mixing hopper 100 in a certain proportion, the cover plate is covered, and the mixing mechanism 200 is started; after fully mixing for a period of time, a concrete-like material can be made, and then the electric discharge valve is opened to enable the material to pass through the discharge port 101, the discharge hose 102, and then enter the discharge pipe 703 in sequence.

[0056] In the initial state, the discharge gate 704 at the bottom of the discharge pipe 703 is in a closed state, and the discharge mechanism 700 is located at one side position of one of the curing bins 600 through the three-axis moving mechanism 500, and the two conductive posts 706 are made to contact the front and rear sides of the top surface of the outer frame 601; then the discharge pipe 703 is controlled to extend into the inner pool 602 through the linear module 707, and the discharge mechanism 700 is slowly controlled to move along the length direction of the curing part 400. As Figure 6 shown, while the discharge mechanism 700 advances, it discharges materials. Until the two conductive posts 706 contact the two second conductive sheets 612, the second electromagnet 610 is energized to make the inner pool 602 tilt towards the direction close to the second electromagnet 610. When the conductive post 706 is separated from the second conductive sheet 612, under the reset action of the elastic sheet, the bottom of the inner pool 602 will shake, which is beneficial to shaking and compacting the materials at the bottom of the inner pool 602.

[0057] When the discharge mechanism 700 continues to move, the discharge pipe 703 continuously contracts upward at the same time until the conductive post 706 passes through the two first conductive sheets 611, then the top of the inner pool 602 will shake, as Figure 7 shown, so as to shake and compact the materials at the top of the inner pool 602.

[0058] After the two conductive posts 706 pass through the first conductive sheet 611, the discharge gate 704 closes, and the discharge pipe 703 contracts upward to the maximum extent; as the discharging mechanism 700 continues to move, when the discharge pipe 703 is above the next inner tank body 602, the discharge pipe 703 extends into the inner tank body 602 again, and the discharge gate 704 opens simultaneously, and this process repeats. Until the discharging mechanism 700 moves from one side of a row of curing bins 600 to the other side, the three-axis moving mechanism 500 then controls the discharging mechanism 700 to move to the next row of curing bins 600.

[0059] It is worth mentioning that when the discharge pipe 703 discharges materials into the inner tank body 602 in this embodiment, the discharge pipe 703 is in a continuous translational and rising motion, that is, the discharge position is always in dynamic change, so it is beneficial to evenly fill the inner tank body 602 with materials. At the same time, when the bottom of the inner tank body 602 is filled with materials, under the action of the second electromagnet 610, the bottom of the inner tank body 602 will vibrate, which is beneficial to evenly mix the materials and avoid voids; when the top of the inner tank body 602 is filled with materials, under the action of the first electromagnet 609, the top of the inner tank body 602 will vibrate, further avoiding voids in the materials and ensuring that the amount of materials in each curing bin 600 is consistent.

[0060] When all the curing bins 600 are filled with materials, the staff can take out the curing part 400 and put in another unused curing part 400 to continue the discharging work until all the materials in the mixing hopper 100 are discharged.

[0061] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

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