Description

Technical Field

[0001] The present invention relates to the technical field of cracking furnaces, and specifically to an environmentally friendly intermittent cracking furnace. Background Art

[0002] A cracking furnace is a key piece of equipment in the petrochemical industry. During the Spring Festival of the Year of the Snake, it still plays an irreplaceable role in industrial production. Through a high-temperature environment, generally reaching 800°C - 900°C or even higher, it causes the cracking reaction of petroleum hydrocarbon raw materials. This complex chemical reaction can decompose large-molecule hydrocarbon substances into small-molecule olefins such as ethylene and propylene. These olefins are the basic raw materials for manufacturing many chemical products such as plastics, rubbers, and fibers, and are crucial for the development of modern industry.

[0003] The patent application with the application number CN202311399040.3 discloses an environmentally friendly intermittent cracking furnace, including a cracking furnace body, a connecting pipe, and a condenser installed on one side of the cracking furnace body.

Specific embodiments

[0020] 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.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example 1: Refer to Figures 1 - 5, the present invention provides a technical solution: an environmentally friendly intermittent cracking furnace, including four sets of support legs 1 and a cracking furnace 4. At the top of each of the four sets of support legs 1, there is a fixed connection with a load-bearing plate 2. On one side of the four load-bearing plates 2 close to the cracking furnace 4, they are fixedly connected to the outer wall of the cracking furnace 4. At the bottom of the cracking furnace 4, there is a fixed connection with a bent rod 3. On the side of the bent rod 3 away from the cracking furnace 4, there is a motor 5 installed. The output end of the motor 5 is fixedly connected with a threaded rod 6. It also includes: A rotating mechanism 7. The rotating mechanism 7 includes a first moving ring 701. On one side of the first moving ring 701 close to the threaded rod 6, it is threadedly connected to the outer wall of the threaded rod 6. On the side of the first moving ring 701 away from the threaded rod 6, there is a fixed connection with a first fixing rod 702. On the side of the first fixing rod 702 away from the first moving ring 701, there are two sets of connecting rings 703. The inner walls of the two sets of connecting rings 703 are both slidably connected to the outer wall of the first fixing rod 702. On the right side of the two sets of connecting rings 703, there is a fixed connection with a baffle 705. On the side of the two baffles 705 close to each other, there is a rotating plate 706 rotatably connected through a first rotating shaft. On the side of the two sets of connecting rings 703 close to each other, there is a fixed connection with a first spring 704. By setting the first spring 704, the position of the connecting ring 703 can be flexibly adjusted. During actual operation, the first spring 704 continuously performs contraction and rebound actions. This characteristic ensures that the hook plate 708 plays a good limiting role on the garbage, so that once the garbage is restricted by the hook plate 708, it cannot move randomly. On the side of the two first springs 704 close to each other, there is a fixed connection with a hook plate 708. By setting the hook plate 708, the materials inside the cracking furnace 4 can be turned over up and down. In this way, the garbage in the cracking furnace 4 can be fully heated to ensure a uniform dissolution effect. On the side of the hook plate 708 close to the first fixing rod 702, they are fixedly connected to the outer wall of the first fixing rod 702. The first fixing rod 702, the connecting ring 703, the first spring 704, the baffle 705, the rotating plate 706, and the hook plate 708 are all provided in two sets and are symmetrically arranged with the middle of the first moving ring 701 as the center. The hook plate 708 is used for collecting garbage.

[0024] The working principle of this embodiment is as follows: When the staff starts the garbage treatment process in the cracking furnace 4, the motor 5 starts synchronously. During the operation of the motor 5, the threaded rod 6 is driven to rotate synchronously, and then the first moving ring 701 on the outer wall of the threaded rod 6 rotates. The first moving ring 701 then advances into the garbage. While the first moving ring 701 moves, the first fixing rod 702 moves accordingly, driving the connecting ring 703 to move synchronously. When the connecting ring 703 moves, the first spring 704 also moves synchronously. When the connecting ring 703 contacts the garbage, its position on the first fixing rod 702 will shift, causing the first fixing rod 702 to push the first spring 704 to contract. The movement of the connecting ring 703 will drive the baffle 705 to act synchronously, and the baffle 705 then pushes the rotating plate 706 to move downward. At this time, the arc-shaped hook plate 708 contacts the garbage and, during the downward movement, brings the garbage at the top to the bottom. When the hook plate 708 moves to the bottom, the motor 5 starts to reverse. At this time, the hook plate 708 rotates in the garbage with the center of the first fixing rod 702 as the axis, causing the garbage brought to the bottom to scatter due to the rotation at the connection of the hook plate 708. When the hook plate 708 completes a 180-degree rotation, it will bring the garbage at the bottom to the top again.

[0025] Embodiment 2: Please refer to Figures 6 - 7, on the basis of the first embodiment, the present invention provides a technical solution: further comprising a stirring mechanism 8, the stirring mechanism 8 includes a second moving ring 801, and both sides of the second moving ring 801 close to the threaded rod 6 are threadedly connected to the outer wall of the threaded rod 6. A contact plate 802 is arranged on the outer wall of the second moving ring 801. One side of the contact plate 802 close to the second moving ring 801 is fixedly connected to the outer wall of the second moving ring 801. A sliding block 803 is arranged on the inner wall of the contact plate 802. The second moving ring 801 is used to adjust the position of the contact plate 802. One side of the sliding block close to the contact plate 802 is slidably connected to the inner wall of the contact block 802. A third spring 805 is arranged on the top of the sliding block 803. One side of the third spring 805 close to the sliding block 803 is fixedly connected to the top of the sliding block 803. The side of the third spring 805 away from the sliding block 803 is fixedly connected to a first shaking plate 806. One side of the first shaking plate 806 close to the contact plate 802 is rotatably connected to the contact plate 802 through a second rotating shaft. The first shaking plate 806 is used to break up the garbage in the cracking furnace 4. One side of the third spring 805 close to the sliding block 803 is fixedly connected to the top of the sliding block 803. The side of the third spring 805 away from the sliding block 803 is fixedly connected to a first shaking plate 806. Inside the cracking furnace 4, by arranging the first shaking plate 806 and the second shaking plate 807, the garbage therein can be fully stirred to ensure that there is no dead angle in the garbage stirring. At the same time, the first shaking plate 806 and the second shaking plate 807 can also cooperate with the hook plate 708. When the hook plate 708 lifts the garbage, the two can timely disperse the garbage to each area, so that the garbage can be evenly heated at each position in the cracking furnace 4, effectively improving the processing efficiency and quality. One side of the first shaking plate 806 close to the contact plate 802 is rotatably connected to the contact plate 802 through a second rotating shaft. The third spring 805 is used to pull the first shaking plate 806 to rotate. A fourth spring 808 is fixedly connected to the bottom of the sliding block 803. The side of the third spring 805 away from the second moving ring 801 is fixedly connected to a second shaking plate 807. One side of the second shaking plate 807 close to the contact plate 802 is rotatably connected to the contact plate 802 through a second rotating shaft. The contact plate 802, the sliding block 803, the second spring 804, the third spring 805, the first shaking plate 806, the second shaking plate 807 and the fourth spring 808 are all arranged in two groups and are symmetrically arranged with the middle of the second moving ring 801 as the center. The second spring 804 is used to ensure that the sliding block 803 can be reset in time.

[0026] The working principle of this embodiment is as follows: When the threaded rod 6 rotates, it will drive the second moving ring 801 to move downward. At the same time, during the downward movement of the first moving ring 701, it will drive the contact plate 802 to move downward together. As the second moving ring 801 rotates, the contact plate 802 also starts to rotate synchronously. During the rotation of the contact plate 802, it will drive the first shaking plate 806 and the second shaking plate 807 to rotate. When these two shaking plates rotate, they will rotate on the contact plate 802, thereby realizing the dispersion of garbage. When the first shaking plate 806 encounters garbage during rotation, it will be pushed by the garbage and rotate towards the side closer to the contact plate 802. In this way, the first shaking plate 806 can disperse the garbage more fully during rotation. When the first shaking plate 806 rotates, it will pull the third spring 805 to stretch. While the third spring 805 stretches, it will drive the sliding block 803 to move, and further cause the sliding block 803 to push the second spring 804 to contract. In addition, when the first shaking plate 806 and the second shaking plate 807 rotate, they will also disperse the garbage brought up by the hook plate 708 to ensure more uniform stirring of the garbage.

[0027] Embodiment 3: Please refer to Figure 8 , based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: It further includes an adjusting mechanism 9. The adjusting mechanism 9 includes a third moving ring 901. One side of the third moving ring 901 close to the threaded rod 6 is threadedly connected to the outer wall of the threaded rod 6. The side of the third moving ring 901 far from the threaded rod 6 is fixedly connected with a telescopic rod 902. The telescopic rod 902 is mainly used to adjust the distance. Its design is extremely ingenious. When dealing with different types and accumulation degrees of garbage, by operating the telescopic rod 902, the distance between the stirring mechanism 8 and the rotating mechanism 7 can be flexibly adjusted, which enables the device to adapt to various complex garbage treatment scenarios. In addition, the telescopic rod 902 also has the function of independently adjusting the distance between the upper and lower ends. Facing garbage with different masses and densities, it can also ensure the stable and efficient operation of the device, greatly improving the applicability and effect of garbage treatment. Both the upper and lower ends of the telescopic rod 902 are fixedly connected with collar rings 905. One side of the two collar rings 905 far from the third moving ring 901 is fixedly connected with a second fixing rod 906. The collar ring 905 is used to fix the telescopic rod 902. One side of the two second fixing rods 906 far from the third moving ring 901 is fixedly connected with a fitting plate 904. The top of the fitting plate 904 located at the top is fixedly connected with a top plate 903, and the bottom of the fitting plate 904 located at the bottom plate 907 is fixedly connected with a bottom plate 907. The fitting plate 904 is used to drive the top plate 903 or the bottom plate 907 to move.

[0028] The working principle of this embodiment is as follows: When it is necessary to adjust the distance between the stirring mechanism 8 and the rotating mechanism 7, the telescopic rod 902 is pulled to make it move. During the process of the telescopic rod 902 starting to stretch or contract, it will drive the collar 905 to move synchronously. When the collar 905 moves, the second fixed rod 906 also moves accordingly, thereby driving the external fitting plate 904 to move. While the fitting plate 904 moves, it will drive the top plate 903 and the bottom plate 907 to move. It is worth mentioning that the telescopic rod 902 is divided into upper and lower ends and can be adjusted separately, which enables the device to flexibly adjust the distance when facing different types of garbage, so as to stir the garbage more efficiently.
