Description

Technical Field

[0001] This invention belongs to the field of combustion furnace technology, specifically relating to a combustion furnace with a high-efficiency piston-type air cannon. Background Technology

[0002] Piston-type air cannons use a sudden burst of powerful airflow at speeds exceeding Mach 1 to directly penetrate the blocked or faulty area of ​​stored bulk materials. They are a type of ash-removing and descaling device. During the combustion stage of a combustion furnace, ash generated by fuel easily adheres to the furnace wall, flue, or heat exchange surface, forming ash deposits or slag that block the airflow channels. By assembling piston-type air cannons on the combustion furnace, the high-pressure airflow that bursts out instantaneously creates a shock wave and airflow, powerfully clearing the blockages in the combustion furnace.

Each of the four pairs of second energy storage elements is provided on one of the four pairs of hinge bars.

[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, a first and second annular discs are assembled on channel one and channel two. When channel one and channel two are connected, the maintenance worker aligns channel one with channel two, causing the second annular cover to extend into the first annular cover. The corrugated topology of the second and first annular covers ensures a tight seal between channel one and channel two. After the second annular cover extends into the first annular cover, the connecting member extends out of the opening of the first annular cover and contacts the second screw-in guide groove of the first annular disc. The maintenance worker uses a screwdriver to rotate the linkage lever through the first notch. The rotating linkage lever, through the engagement member, drives the rotating lever, the first stop block, and the connecting member to rotate together. The rotating connecting member engages with the second screw-in guide groove of the first annular disc, and the connecting member shifts away from the rotating lever. The connecting member then becomes pressed against the elastic block along with the first stop block. Through the rebound of the elastic block, the connecting member... The first annular disk is held in place by the second spiral guide groove of the first annular disk. The first and second annular disks smoothly connect channels one and two. The third spiral guide groove of the linkage rod rotates and presses against a pair of positioning inserts, causing a pair of assembly blocks to shift away from each other. It also causes a pair of first bonding blocks to shift away from each other. The pair of first bonding blocks shifts with two pairs of inclined guide seats, pressing against two pairs of guide blocks and causing a pair of second bonding blocks to shift away from each other. The pair of first bonding blocks and the pair of second bonding blocks press against the inner wall of the second annular cover, so that the outer wall of the second annular cover is in close contact with the inner wall of the first annular cover, which facilitates the close connection between channels one and two. After the material is burned, it is sprayed into the combustion furnace through the piston air cannon, channels one and two to clean the solid waste residue in the combustion furnace.

[0017] 2. This invention takes into account that the second and first ring covers are prone to morphological changes and volume expansion when heated. If the first and second bonding blocks are pressed together for a long time, it can easily cause permanent damage to the second and first ring covers, which is not conducive to the efficient operation of the piston air cannon and the combustion furnace. After the combustion furnace has finished operating, the maintenance personnel can rotate a pair of connecting covers to displace a pair of first screw-in guide grooves that press against a pair of guide covers. Rotating the first screw-in guide grooves again will cause the guide covers to snap into the second recess. The displacement of the guide covers will cause the linkage block to shift via the support rod. The first energy storage element will be pressed and contracted, and will be displaced away from the linkage rod via the multi-guide rails to the side where the positioning insert is pressed against the linkage rod. This will separate the positioning insert from the third screw-in guide groove of the linkage rod, allowing the first and second bonding blocks to... The bonding block does not press against the second ring cover. Then, the maintenance worker rotates the connecting cover in the opposite direction to separate the guide cover from the second recess. The first energy storage component rebounds, causing the linkage block to return to its original state. The multi-guide rail presses against the positioning insert to return it to its original position and contact the third screw-in guide groove of the linkage rod again. The linkage block, through the support rod, carries the guide cover to press against the first screw-in guide groove, allowing the connecting cover to return to its original state. This facilitates the maintenance of the connection between the combustion furnace and the piston air cannon, and promotes the efficient operation of the combustion furnace and the piston air cannon. When the piston air cannon needs to be removed for maintenance, the maintenance worker uses a screwdriver to rotate the linkage rod in the opposite direction through the first recess, and then through the biting component to make the connecting component rotate in the opposite direction to separate it from the second screw-in guide groove of the first ring plate. Finally, the maintenance worker pulls the second ring cover out from the first ring cover.

[0018] 3. When the first and second bonding blocks are pressed against the second ring cover, the distance between the first and second bonding blocks increases. The first and second bonding blocks cause a pair of rotating blocks on the same hinge bar to rotate via the second stop block. The second energy storage member is deformed by the rotation. The rotating blocks plug the gap between the first and second bonding blocks and can press against the area of ​​the second ring cover that is not pressed, so as to press against the surface of the second ring cover and promote the tight connection between channel one and channel two. When the first and second bonding blocks are not pressing against the second ring cover, the first and second bonding blocks do not pull the rotating blocks via the second stop block. The second energy storage member returns to its original state, causing the rotating blocks to return to their original state.

An elastic block 505 is provided between the pair of connecting members 504 and the pair of first stop blocks 503. The elastic block 505 is located inside the connecting member 504.

[0045] The engagement member 502 includes a pair of engagement bevel gear discs, one of which is fixed to both sides of the linkage lever 500, and the other is fixed to the rotating lever 501.

[0046] The disengagement unit includes a pair of assembly blocks 600, each of which is located on a pair of third screw-in guide grooves of the linkage rod 500. Both sides of the pair of assembly blocks 600 are in contact with the inner wall of the second annular disc 401. Each pair of assembly blocks 600 slides into a positioning insert 601 on the pair of assembly blocks 600. The assembly blocks 600 are moved via the third screw-in guide grooves of the linkage rod 500. One side of each positioning insert 601 is located in a pair of third screw-in guide grooves of the linkage rod 500. A linkage block 602 slides on the assembly block 600 to hold the positioning insert 601. The linkage block 602 has multiple guide rails 607 pre-installed. The two sides of each positioning insert 601 are connected to two... The multi-guide rail 607 is slidably connected, and the linkage block 602 is connected to the assembly block 600 via the first energy storage component 603. A pair of linkage blocks 602 are fixedly connected to the opposite sides of each other via a support rod 604. A pair of support rods 604 are slidably connected to guide covers 605. The pair of guide covers 605 are arranged in a mirror image. One side of each pair of guide covers 605 is slidably connected to both sides of the second ring disc 401. Both sides of the linkage rod 500 are provided with connecting covers 606. A first screw-in guide groove 608 is reserved on each pair of connecting covers 606. One side of each pair of guide covers 605 is located in a pair of first screw-in guide grooves 608. A second notch 609 is reserved on each pair of first screw-in guide grooves 608 to lock the guide cover 605.

[0047] The multi-guide rail 607 includes a slant rail and a pair of straight rails, with the pair of straight rails located on both sides of the slant rail and connected to it.

[0048] The bonding unit includes a first bonding block 700 fixedly connected to a pair of assembly blocks 600. The first bonding block 700 is slidably connected to the inner wall of the second annular disk 401. Two pairs of inclined guide seats 701 are fixedly connected inside the first bonding block 700. Guide blocks 702 are slidably connected on the inclined guide seats 701. A second bonding block 703 is fixedly connected between a pair of guide blocks 702. The first bonding block 700 and the second bonding block 703 are used to bond to the inner wall of the second annular cover 403.

[0049] The first bonding block 700 and the second bonding block 703 are provided with several arc-shaped protrusions, which facilitates bonding to the inner wall of the second ring cover 403.

[0050] After the material is burned, it is sprayed into the combustion furnace 100 through the piston air cannon 200, channel one 201 and channel two 101 to clean the solid waste residue in the combustion furnace 100.

[0051] The maintenance worker assembles the first ring plate 400 and the second ring plate 401 onto channel one 201 and channel two 101. When channel one 201 and channel two 101 are connected, the maintenance worker positions channel one 201 facing channel two 101, causing the second ring cover 403 to extend into the first ring cover 402. The corrugated topology of the second ring cover 403 and the first ring cover 402 ensures a tight seal between channel one 201 and channel two 101. After the second ring cover 403 extends into the first ring cover 402, the connecting parts... 504 extends out of the opening of the first annular cover 402 and contacts the second screw-in guide groove of the first annular disc 400. The maintenance worker uses a screwdriver to rotate the linkage lever 500 through the first notch 506. The rotating linkage lever 500 drives the rotating lever 501, the first stop block 503, and the connecting piece 504 to rotate together via the engaging piece 502. The connecting piece 504 rotates and engages with the second screw-in guide groove of the first annular disc 400. The connecting piece 504 moves away from the rotating lever 501. The first stop block 503 is pressed against the elastic block 505. Through the rebound of the elastic block 505, the connecting member 504 is supported by the second screw-in guide groove of the first annular disc 400. The first and second annular discs 401 smoothly connect the first channel 201 and the second channel 101. The third screw-in guide groove of the linkage lever 500 rotates and presses against a pair of positioning inserts 601, causing a pair of assembly blocks 600 to shift away from each other, and causing a pair of first stop blocks 601 to shift away from each other. The first mating blocks 700 shift to the side away from each other, and the pair of first mating blocks 700 shift along with the two pairs of inclined guide seats 701, pressing against the two pairs of guide blocks 702 to cause the pair of second mating blocks 703 to shift to the side away from each other. The pair of first mating blocks 700 and the pair of second mating blocks 703 press against the inner wall of the second ring cover 403 together, so that the outer wall of the second ring cover 403 is in close contact with the inner wall of the first ring cover 402, which is conducive to the close contact between the first channel 201 and the second channel 101.

[0052] Because the second ring cover 403 and the first ring cover 402 are prone to shape changes and volume expansion when heated, if the first bonding block 700 and the second bonding block 703 are pressed together for a long time, it is easy to cause permanent damage to the second ring cover 403 and the first ring cover 402, which is not conducive to the efficient operation of the piston air cannon and the combustion furnace. After the combustion furnace is completed, the maintenance personnel can rotate a pair of connecting covers 606 to make a pair of first screw-in guide grooves 608 press against a pair of guide covers 605 to change position. Rotating the first screw-in guide grooves 608 again will make the guide covers 605 snap into the second notch 609. The change of the guide covers 605 causes the linkage block 602 to move through the support rod 604. The first energy storage element 603 is pressed and contracted, and through the multi-guide rail 607, it presses the positioning insert 601 to the side away from the linkage rod 500, so that the positioning insert 601 separates from the third screw-in guide groove of the linkage rod 500, and the first bonding block 700 and the second bonding block 703 are pressed against each other to change position. 03. Without pressing the second ring cover 403, the maintenance worker then reverses the rotation of the connecting cover 606, causing the guide cover 605 to separate from the second notch 609. The first energy storage element 603 rebounds, causing the linkage block 602 to return to its original position. The multi-guide rail 607 presses against the positioning insert 601, causing it to return to its original position and contact the third screw-in guide groove of the linkage lever 500 again. The linkage block 602, via the support lever 604, carries the guide cover 605 to press against the first screw-in guide groove 608, causing the connecting cover 606 to... 6. Returning to the original state facilitates the maintenance of the connection between the combustion furnace and the piston air cannon, and promotes the efficient operation of the combustion furnace and the piston air cannon. When the piston air cannon needs to be removed for inspection and maintenance, the maintenance personnel use a screwdriver to rotate the linkage lever 500 in the reverse direction through the first notch 506, and then cause the connecting piece 504 to rotate in the reverse direction through the biting piece 502 to separate it from the second screw guide groove of the first ring plate 400. Then the maintenance personnel forcefully pull the second ring cover 403 out from the first ring cover 402.

[0053] A plugging unit is assembled between the first bonding block 700 and the second bonding block 703. The plugging unit includes eight pairs of second stop blocks 300. A pair of second stop blocks 300 are fixedly connected to both sides of the first bonding block 700 and the second bonding block 703. A rotating block 301 is screwed onto the limiting plate to plug the gap between the first bonding block 700 and the second bonding block 703. A hinge bar is screwed between a pair of rotating blocks 301. There are four pairs of hinge bars. A second energy storage element 302 is provided between a pair of rotating blocks 301. The first energy storage element 12 has the characteristic of storing and dissipating torsional energy. There are four pairs of second energy storage elements 302. Each of the four pairs of second energy storage elements 302 is provided on one of the four pairs of hinge bars.

[0054] When the first bonding block 700 and the second bonding block 703 press against the second annular cover 403, the gap between the first bonding block 700 and the second bonding block 703 increases. The first bonding block 700 and the second bonding block 703 cause a pair of rotating blocks 301 on the same hinge bar to rotate via the second stop block 300. The second energy storage member 302 is deformed by the rotation. The rotating block 301 rotates to block the gap between the first bonding block 700 and the second bonding block 703, and can press against the area of ​​the second annular cover 403 that has not been pressed, so as to press against the surface of the second annular cover 403 and promote the tight connection between channel one 201 and channel two 101. When the first bonding block 700 and the second bonding block 703 do not press against the second annular cover, the first bonding block 700 and the second bonding block 703 do not pull the rotating block 301 via the second stop block 300. The second energy storage member 302 returns to its original state, causing the rotating block 301 to return to its original state.
