Description

Technical Field

[0001] This application relates to the field of foam material preparation technology, and more specifically, to a continuous preparation apparatus for preparing foam materials using fly ash. Background Technology

[0002] While municipal solid waste incineration projects have played a positive role in waste reduction, the fly ash produced has become a new challenge for environmental protection in some cities. Improper management and disposal of fly ash from municipal solid waste incineration can cause secondary environmental pollution and health impacts.

[0003] Municipal solid waste incineration fly ash refers to the ash collected by the flue gas purification system of municipal solid waste incineration facilities, as well as the bottom ash settling at the bottom of the flue and chimney. The particle size of fly ash generally ranges from 0.3 to 300 μm, with a high specific surface area and strong activity. It contains a large amount of soluble chloride salts; it is enriched with large amounts of toxic heavy metals such as Zn, Pb, Cu, Cr, Ni, Mn, As, Cd, Co, Ag, and Hg; and it is also enriched with large amounts of dioxins. It is a dual hazardous waste possessing both heavy metal hazard characteristics and persistent organic toxicity characteristics, posing a significant threat to human health and the ecological environment.

[0004] In existing technologies, fly ash can be used to prepare foamed ceramic slabs, thus achieving waste utilization. The process typically involves mixing fly ash with other raw materials (such as clay, feldspar, and foaming agents) to form a homogeneous slurry, then casting, drying, and finally sintering in a high-temperature kiln to form a porous ceramic body. However, current production technologies generally use fixed-size molds for integral casting and firing, resulting in only large-sized blanks of uniform specifications. In practical applications, it is often necessary to cut large slabs into smaller slabs of different sizes according to usage requirements. This subsequent cutting process not only increases production steps and time, leading to reduced overall production efficiency, but also generates additional scrap waste, increasing raw material costs. Furthermore, the cutting process easily causes edge damage to the slabs, affecting product yield and quality stability, while also limiting the flexibility of the production process and the ability to quickly respond to diverse market demands. Summary of the Invention

[0005] In view of this, this application provides a continuous preparation apparatus for preparing foamed materials using fly ash, so as to solve the technical problems of low production efficiency and poor quality stability of the foamed boards produced by using fly ash in the prior art.

[0006] This application provides a continuous preparation apparatus for preparing foamed materials using fly ash, wherein the continuous preparation apparatus for preparing foamed materials using fly ash includes:

[0007] A foamed board molding die includes a bottom box and a top cover. The bottom box is used to hold the slurry prepared from waste fly ash. Multiple movable partitions are provided below the top cover. The partitions can move along the length or width of the top cover. When the top cover seals the bottom box, the partitions can divide the interior of the bottom box into multiple rectangular spaces.

[0009] A closing actuator is located at the output end of the first conveyor line and is used to extract the top cover output from the output end of the first conveyor line and seal the extracted top cover onto the bottom box on the second conveyor line to form a box assembly to be heated.

[0010] At least two firing furnaces are used to receive the box assembly to be heated.

[0011] Furthermore, a sliding channel is formed on the upper cover, the sliding channel extends along the length direction of the upper cover and penetrates the upper cover along the thickness direction of the upper cover, a lever is connected to the upper end of the partition plate, the lever passes through the sliding channel and protrudes upward from the upper surface of the upper cover, a support rod is connected to the lever, the support rod is supported on the upper surface of the upper cover, and the lever can slide along the sliding channel to drive the partition plate to move along the length direction of the upper cover.

[0012] Furthermore, the upper surface of the cover has fixing grooves formed on both sides of the sliding channel, the fixing grooves are parallel to the sliding channel, and locking rods are provided at both ends of the support rod, the locking rods extending into the corresponding fixing grooves and being able to lock in the fixing grooves.

[0013] Furthermore, the two side walls of the fixing groove form a plurality of arc-shaped concave surfaces extending along the length direction of the fixing groove, and the locking rod is an elastic round rod that can be engaged between two opposing arc-shaped concave surfaces on the two side walls of the fixing groove, and the elastic round rod can move along the length direction of the fixing groove under external force.

[0014] Furthermore, the continuous preparation device for preparing foamed materials using fly ash includes an automatic actuation mechanism. The automatic actuation mechanism includes an automatic actuation drive device and an actuation plate connected to the automatic actuation drive device. The actuation plate is disposed above the first conveying line. The automatic actuation drive device can drive the actuation plate to move along the length direction of the sliding channel of the upper cover located on the first conveying line, so as to actuate the lever on the upper cover located on the first conveying line to move along the corresponding sliding channel.

[0015] Furthermore, the continuous preparation device for preparing foamed materials using fly ash includes a first moving vehicle disposed on one side of the first conveyor line. A crossbeam located above the first conveyor line is connected to the first moving vehicle. A first lateral movement drive mechanism is disposed on the crossbeam. A first lifting mechanism is installed on the first lateral movement drive mechanism. The first lateral movement drive mechanism drives the first lifting mechanism to move across the top of the first conveyor line along a first straight line direction. The actuating plate is connected to the first lifting mechanism. The first moving vehicle can move along a second straight line direction. The first straight line direction is perpendicular to the conveying direction of the first conveyor line, and the second straight line direction is parallel to the conveying direction of the first conveyor line. The speed at which the first moving vehicle moves along the second straight line direction is greater than the conveying speed of the top cover on the first conveyor line.

[0016] Furthermore, the first conveyor line includes two spaced-apart sliding beams, the length of which extends along the conveying direction of the first conveyor line. Each sliding beam has a sliding groove facing each other, the sliding groove extending through both ends of the corresponding sliding beam along its length. The two ends of the upper cover on the first conveyor line are respectively limited in the sliding grooves of each sliding beam. Each sliding beam includes multiple friction wheels disposed in the sliding grooves, the multiple friction wheels being arranged along the length of the sliding beam. When the friction wheels rotate, they can frictionally drive the upper cover limited in the sliding grooves of each sliding beam to move along the conveying direction of the first conveyor line. Each friction wheel is connected to a rotating shaft passing through the sliding beam, a drive pulley is disposed on the rotating shaft, and a drive belt is connected to the outer side of the drive pulley of each friction wheel. A motor is mounted on the sliding beam, and the corresponding drive pulley of each sliding beam is connected to the motor for transmission.

[0017] Furthermore, the continuous preparation device for preparing foamed materials using fly ash includes a cover receiving frame disposed at the output end of the first conveyor line. The cover output from the output end of the first conveyor line falls onto the cover receiving frame. The conveying direction of the second conveyor line is perpendicular to the conveying direction of the first conveyor line. The closing execution mechanism includes a second moving carriage, a second lifting mechanism, a second lateral movement drive mechanism, a suction cup frame, and a suction cup installed below the suction cup frame. The second moving carriage is located on one side of the second conveyor line and can move along a third straight line direction, which is parallel to the conveying direction of the second conveyor line. The second lifting mechanism is installed on the second moving carriage, and the second lateral movement drive mechanism is installed on the second lifting mechanism. The suction cup frame is connected to the second lateral movement drive mechanism. The suction cup can pick up the cover on the cover receiving frame and seal the picked-up cover onto the bottom box on the second conveyor line.

[0018] Furthermore, the continuous preparation device for preparing foamed materials using fly ash includes a third moving vehicle, which is equipped with a third lifting mechanism and a bottom box receiving platform. The third moving vehicle can move between the output end of the second conveyor line and each of the firing furnaces.

[0019] Furthermore, the firing furnace is provided with multiple layers of placement plates, each of which can support the box assembly to be heated.

[0020] The beneficial effects of the continuous preparation apparatus for preparing foamed materials using fly ash provided by this invention are as follows:

[0021] Compared to existing technologies, the continuous preparation apparatus for preparing foamed materials using fly ash provided by this invention includes a foamed board forming mold comprising a bottom box and a top cover. A first conveyor line transports the top cover, and a second conveyor line transports the bottom box. The bottom box can hold a slurry for preparing foamed ceramic boards (this slurry is made using known processes from waste incineration fly ash and other necessary raw materials). A closing actuator extracts the top cover output from the first conveyor line and seals it onto the bottom box on the second conveyor line to form a heating assembly. The heating assembly is then placed in a firing furnace to fire the slurry in the bottom box into foamed ceramic boards. Depending on the required size of the foamed ceramic boards, a partition plate is selectively moved along the length or width of the top cover to the desired position, dividing the interior of the bottom box into multiple rectangular spaces of the same or different sizes. The process involves dividing the slurry in the bottom box into multiple portions. The heated box assembly is then placed in a firing furnace to produce multiple foamed ceramic sheets of different or identical sizes. This means that a single foamed sheet forming mold can flexibly produce multiple foamed ceramic sheets of the same or different sizes, eliminating the need to first form a large foamed ceramic sheet and then cut it into multiple sheets of different or identical sizes. This improves the production efficiency of foamed ceramic sheet preparation and avoids damage caused by cutting the sheets. Furthermore, since at least two firing furnaces are available, while one furnace is firing the slurry to form foamed ceramic sheets, the other furnace can still cooperate with the first conveyor line, the second conveyor line, and the closing actuator to transport the top cover, the bottom box, form the heated box assembly, and place the heated box assembly into the firing furnace that is not currently firing, thus achieving continuous preparation of foamed materials (foamed ceramic sheets).

[0039] See Figures 1 to 10 This application provides a continuous preparation apparatus for preparing foamed materials using fly ash, particularly for preparing foamed ceramic panels. The continuous preparation apparatus for preparing foamed materials using fly ash includes:

[0040] The foam board forming mold includes a bottom box 100 and a top cover 200. The bottom box 100 is used to hold the slurry prepared from waste fly ash. Multiple movable partition plates 1 are provided below the top cover 200. The partition plates 1 can move along the length or width of the top cover 200. When the top cover 200 covers the bottom box 100, the partition plates 1 can divide the interior of the bottom box 100 into multiple rectangular spaces 102.

[0041] First conveyor line 300 and second conveyor line 2, the first conveyor line 300 is used to convey the top cover 200 and the second conveyor line 2 is used to convey the bottom box 100;

[0042] A closing actuator is located at the output end of the first conveyor line 300 and is used to extract the upper cover 200 output from the output end of the first conveyor line 300 and seal the extracted upper cover 200 onto the bottom box 100 on the second conveyor line 2 to form a box assembly to be heated. The upper end of the bottom box 100 has a rectangular frame 101, and the lower end of the upper cover 200 has a rectangular frame groove 201 that mates with the rectangular frame 101. When the upper cover 200 is sealed onto the bottom box 100, the rectangular frame 101 is sealed and engaged with the rectangular frame groove 201.

[0043] At least two firing furnaces 400 are used to receive the box assembly to be heated.

[0044] The continuous preparation apparatus for preparing foamed materials using fly ash provided by this invention includes a foamed board forming mold comprising a bottom box 100 and a top cover 200. A first conveyor line 300 is used to convey the top cover 200, and a second conveyor line 2 is used to convey the bottom box 100. The bottom box 100 can hold a slurry for preparing foamed ceramic boards (this slurry is made using known process technology from waste incineration fly ash and other necessary raw materials). A closing actuator is used to extract the top cover 200 output from the output end of the first conveyor line 300 and... The top cover 200 is sealed onto the bottom box 100 on the second conveyor line 2 to form a box assembly to be heated. The box assembly to be heated is then placed into the firing furnace 400 for firing, which fires the slurry inside the bottom box 100 into a foamed ceramic slab. Depending on the required size of the foamed ceramic slab, the partition plate 1 is selectively moved along the length or width of the top cover 200 to the desired position, so that the partition plate 1 divides the interior of the bottom box 100 into multiple rectangular spaces 102 of the same or different sizes, thereby inserting the partition plate 1 into the bottom box. The slurry in box 100 is divided into multiple portions. The heated box assembly is then placed in furnace 400 to fire and form multiple foamed ceramic sheets of different or identical sizes. This means that a single foamed ceramic sheet molding mold can flexibly form multiple foamed ceramic sheets of the same or different sizes, eliminating the need to first form a large, single foamed ceramic sheet and then cut it into multiple sheets of different or identical sizes. This improves the production efficiency of foamed ceramic sheet preparation and avoids the problems caused by cutting the foamed ceramic sheet. In addition to the damage to the sheet material, since there are at least two firing furnaces 400, when one firing furnace 400 is firing slurry to form foamed ceramic sheet material, the other firing furnace 400 can still cooperate with the first conveyor line 300, the second conveyor line 2, and the closing actuator to carry out the conveying operation of the top cover 200, the conveying operation of the bottom box 100, the operation of forming the box assembly to be heated, and the operation of placing the box assembly to be heated into the firing furnace 400 that has not been fired, so as to realize the continuous preparation of foamed material (foamed ceramic sheet material).

[0045] According to a specific embodiment of this application, four partition plates 1 are arranged along the length of the upper cover 200. Therefore, the four partition plates 1 can divide the bottom box 100 into five identical or different rectangular spaces 102 along its length. When all four partition plates 1 are attached in sequence, the bottom box 100 can be divided into two identical or different rectangular spaces 102 along its length. When any two partition plates 1 are attached, the bottom box 100 can be divided into three identical or different rectangular spaces 102 along its length, and so on. Of course, as other embodiments, two, three, five or more partition plates 1 can also be arranged along the length (or width) of the upper cover 200.

[0046] According to one embodiment of this application, a sliding channel 202 is formed on the top cover 200. The sliding channel 202 extends along the length direction of the top cover 200 and penetrates the top cover 200 along the thickness direction. A lever 3 is connected to the upper end of the partition plate 1. The lever 3 passes through the sliding channel 202 and protrudes upward from the upper surface of the top cover 200. A support rod 4 is connected to the lever 3. The support rod 4 is supported on the upper surface of the top cover 200. The lever 3 can slide along the sliding channel 202 to drive the partition plate 1 to move along the length direction of the top cover 200. As needed, the lever 3 can be moved to a suitable position relative to the sliding channel 202 to correspond to the size of each space divided in the bottom box 100 after the top cover 200 seals the bottom box 100.

[0047] According to one embodiment of this application, the upper surface of the cover 200 has fixing grooves 203 formed on both sides of the sliding channel 202. The fixing grooves 203 are parallel to the sliding channel 202. The two ends of the support rod 4 are respectively provided with locking rods 5. The locking rods 5 extend into the corresponding fixing grooves 203 and can be locked in the fixing grooves 203. For example, the locking rods 5 can be threaded rods, and locking nuts can be installed on the threaded rods. In this way, the locking rods 5 can be locked in any position of the fixing grooves 203, realizing stepless adjustment of the position of the partition plate 1 along the length direction of the cover 200. Thus, a rectangular space 102 of any size can be steplessly divided within the original size range of the bottom box 100. The molded foamed ceramic plate can greatly adapt to the needs of diverse sizes.

[0048] According to one embodiment of this application, the two side walls of the fixing groove 203 form a plurality of arc-shaped concave surfaces 204 extending along the length direction of the fixing groove 203. The locking rod 5 is an elastic round rod, which can be engaged between two opposing arc-shaped concave surfaces 204 on the two side walls of the fixing groove 203. The elastic round rod can move along the length direction of the fixing groove 203 under external force, so there is no need to set up additional structures such as locking nuts to fix the elastic round rod. However, in this embodiment, the elastic round rod cannot be locked at any position in the fixing groove 203. It needs to be locked between each pair of arc-shaped concave surfaces 204 along the length direction of the fixing groove 203. The plurality of arc-shaped concave surfaces 204 extending along the length direction of the fixing groove 203 should be as large as possible (e.g., more than 30). This can also greatly meet the needs of the molded foamed ceramic board to adapt to the diversity of sizes.

[0049] According to one embodiment of this application, a continuous preparation apparatus for preparing foamed materials using fly ash includes an automatic actuation mechanism. The automatic actuation mechanism includes an automatic actuation drive device and an actuation plate 6 connected to the automatic actuation drive device. The actuation plate 6 is disposed above the first conveying line 300. The automatic actuation drive device can drive the actuation plate 6 to move along the length direction of the sliding channel 202 of the upper cover 200 located on the first conveying line 300, so as to actuate the lever 3 on the upper cover 200 located on the first conveying line 300 to move along the corresponding sliding channel 202.

[0050] According to a specific embodiment of this application, a continuous preparation device for preparing foamed materials using fly ash includes a first moving carriage 7 disposed on one side of a first conveyor line 300. A crossbeam 8 located above the first conveyor line 300 is connected to the first moving carriage 7. A first lateral movement drive mechanism 9 (e.g., an electrically controlled guide rail) is disposed on the crossbeam 8. A first lifting mechanism 10 (e.g., a lifting cylinder) is mounted on the first lateral movement drive mechanism 9. The first lateral movement drive mechanism 9 drives the first lifting mechanism 10 to move across the top of the first conveyor line 300 along a first linear direction. A toggle plate 6 is connected to the first lifting mechanism 10. The first moving carriage 7 can move along a second linear direction. Specifically, one side of the first conveyor line 300 has a ground rail 11 extending along the second linear direction. The lower part of the first moving carriage 7 has a guide groove that limits and cooperates with the ground rail 11. The first moving vehicle 7 moves at a speed greater than that of the upper cover 200 on the first conveyor line 300, with the second straight direction parallel to the first conveyor line 300. The first moving vehicle 7 can move at a faster speed relative to the first conveyor line 300. This ensures that while the upper cover 200 is being conveyed on the first conveyor line 300, after the actuating plate 6 has actuated one lever 3, the first moving vehicle 7 quickly moves to catch up with the moving upper cover 200, so that the actuating plate 6 can perform the actuation operation of another lever 3. Specifically, the actuating plate 6 can be lowered below the upper surface of the lever 3 by the first lifting mechanism 10, and then the first lateral drive mechanism 9 drives the first lifting mechanism 10 to move, which can drive the actuating plate 6 to actuate the lever 3 along the first straight direction.

[0051] According to one embodiment of this application, a first conveyor line 300 includes two spaced-apart sliding beams 301. The length direction of the sliding beams 301 extends along the conveying direction of the first conveyor line 300. Each sliding beam 301 has a sliding groove 302 facing each other. The sliding groove 302 extends through both ends of the corresponding sliding beam 301 along its length direction. The two ends of the upper cover 200 on the first conveyor line 300 are respectively limited in the sliding groove 302 of each sliding beam 301. The sliding beam 301 includes a plurality of friction wheels 303 disposed in the sliding groove 302. The friction wheels 303 are arranged along the length of the sliding beam 301. When the friction wheels 303 rotate, they can drive the upper cover 200, which is limited in the sliding groove 302 of each sliding beam 301, to move along the conveying direction of the first conveying line 300. Each friction wheel 303 is connected to a rotating shaft 304 that passes through the sliding beam 301. A transmission pulley 305 is provided on the rotating shaft 304. A transmission belt 306 is connected to the outside of the transmission pulley 305 of each friction wheel 303. A motor 307 is installed on the sliding beam 301. The corresponding transmission pulley 305 of each sliding beam 301 is connected to the motor 307 for transmission.

[0052] According to one embodiment of this application, the second conveyor line 2 may be a roller conveyor.

[0053] According to one embodiment of this application, a continuous preparation apparatus for preparing foamed materials using fly ash includes a top cover receiving frame disposed at the output end of a first conveyor line 300. The top cover receiving frame includes two parallel L-shaped beams 12. After the top cover 200 detaches from the sliding beam 301, the two ends of the top cover 200, which was previously limited in the sliding grooves 302 of each sliding beam 301, are supported on the two L-shaped beams 12. The top cover 200 output from the output end of the first conveyor line 300 falls onto the top cover receiving frame. The conveying direction of the second conveyor line 2 is perpendicular to the conveying direction of the first conveyor line 300. The closing actuator includes a second moving carriage 13, a second lifting mechanism 14 (e.g., an upright electrically controlled guide rail), a second transverse drive mechanism 15 (e.g., a horizontally placed electrically controlled guide rail), a suction cup frame 16, and a suction cup 17 installed below the suction cup frame 16. The second moving carriage 13 is located on one side of the second conveyor line 2 and can move along the third straight direction, which is parallel to the conveying direction of the second conveyor line 2. The second lifting mechanism 14 is installed on the second moving carriage 13, and the second lateral drive mechanism 15 is installed on the second lifting mechanism 14. The suction cup frame 16 is connected to the second lateral drive mechanism 15. The suction cup 17 can pick up the upper cover 200 on the upper cover receiving frame and seal the picked-up upper cover 200 onto the bottom box 100 on the second conveyor line 2. The suction cup 17 can be a vacuum suction cup 17 or a magnetic suction cup. When the vacuum suction cup 17 is de-energized, it can release the upper cover 200. If it is a magnetic suction cup, it is an electromagnetic suction cup. When the power is cut off, the magnetism is broken, thereby releasing the upper cover 200. If the suction cup 17 is a magnetic suction cup, the material of the upper cover 200 is a metal material that can be magnetically attracted.

[0054] According to one embodiment of this application, a continuous preparation apparatus for preparing foamed materials using fly ash includes a third moving carriage 18, on which a third lifting mechanism (e.g., a scissor lift mechanism 19) is provided. The third lifting mechanism is provided with a bottom box receiving platform 20. The third moving carriage 18 can move between the output end of the second conveyor line 2 and each firing furnace 400, thereby conveying the box assembly to be heated received from the output end of the second conveyor line 2 to the firing furnace 400. Then, the box assembly to be heated can be pushed into the firing furnace 400 by manual or known electric pushing mechanism.

[0055] According to one embodiment of this application, a multi-layer placement plate 401 is provided in the firing furnace 400, and each placement plate can support the box assembly to be heated. The multi-layer placement plate 401 is located in the firing chamber inside the firing furnace 400. The firing furnace 400 has an openable and closable door 402, which is used to close or open the firing chamber.

[0056] 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.
