Description

Technical Field

[0001] This utility model belongs to the field of CO catalytic combustion furnace technology, and more specifically, it relates to a CO catalytic combustion furnace slag removal device. Background Technology

[0002] The catalytic combustion CO combustion furnace is welded from carbon steel plates, with electric heating tubes and catalysts placed inside, and an external insulation layer and iron plates. The catalytic combustion device consists of an inner liner and an outer shell, both made of carbon steel. A tubular heat exchanger is added to the catalytic combustion device. When the high-temperature gas after combustion passes through the heat exchanger, it transfers some of its heat energy to the untreated low-temperature organic waste gas, making full use of heat energy and saving energy. The catalyst lowers the oxidation reaction temperature and accelerates the chemical reaction rate. The waste gas can be preheated to 200-400℃ for combustion, requiring no long time or high temperature conditions. The organic compounds in the organic waste gas can be quickly decomposed into carbon dioxide and water, thus achieving the purpose of purification. It has advantages such as high heat recovery rate, no secondary pollution, low energy consumption, safety, and long service life.

[0003] Based on the above, the following problems were found: Existing catalytic combustion furnaces usually use filters for filtration. Existing filters are usually cylindrical, and the filter holes are prone to clogging after a period of use, requiring regular cleaning, which results in a high cleaning frequency. At the same time, it is inconvenient to install and disassemble the filter when cleaning it, and it is also inconvenient to discharge the filtered waste residue. Existing disassembly usually involves disassembling the whole thing, which requires removing multiple bolts and is quite inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a CO catalytic combustion furnace slag removal device to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a CO catalytic combustion furnace slag removal device, which solves the current issues of needing to clean regularly, having a high cleaning frequency, and the inconvenience of installing and disassembling the filter screen during cleaning.

[0006] This utility model provides a slag removal device for a CO catalytic combustion furnace, achieved through the following specific technical means:

[0007] A CO catalytic combustion furnace slag removal device includes a furnace body, an exhaust pipe fixedly through the bottom of the furnace body, a top cover hinged to the top of the furnace body, an air inlet pipe fixedly through the top of the top cover, a protective cover fixedly through the middle of one side of the outer wall of the furnace body, a micro motor fixedly to one side of the protective cover, the power output end of the micro motor movably penetrating through the outer wall of the protective cover and fixedly connected to a transmission rod, a slider fixedly to one end of one side of the transmission rod, an impact block slidably connected through the outer wall of the furnace body near the protective cover, a movable sleeve fixedly to one side of the impact block, and a first filter screen placed inside the furnace body.

[0008] Furthermore, the slider is slidably connected to the movable sleeve rod, the protective cover is hollow, and the transmission rod, slider, movable sleeve rod, and impact block are all located inside the protective cover.

[0009] Furthermore, a connecting ring is fixed to the top of the first filter screen, and a limiting ring is fixed to the top of the inner wall of the furnace body, with the connecting ring located at the top of the limiting ring.

[0010] Furthermore, a second filter screen is fixed at the center of the bottom of the first filter screen, and both the outer walls of the first and second filter screens are provided with ventilation holes. The vertical cross-section of the second filter screen is set in the shape of an isosceles trapezoid.

[0011] Furthermore, the distance between one side of the impact block and the outer wall of the first filter screen is less than the length of the transmission rod, and one side of the impact block is used in conjunction with the middle part of the first filter screen.

[0012] Furthermore, a fastening hook rod is provided on the top of the outer wall of the furnace body, and a hook block is fixed on the bottom of the outer wall of the upper cover. The fastening hook rod and the hook block are used together.

[0013] Furthermore, a compression ring is fixed to the bottom of the upper cover, and a sealing ring is fixed to the bottom of both the compression ring and the bottom of the upper cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, by starting a micro motor, the micro motor drives the transmission rod to rotate, which in turn drives the slider to slide inside the moving sleeve rod. This causes the moving sleeve rod to drive the impact block to move laterally back and forth. The impact block intermittently impacts the first filter screen, causing the first filter screen to shake and dislodging some of the impurities blocking the mesh. The second filter screen is located inside the first filter screen and protrudes. Even when impurities are located at the bottom of the first filter screen, the second filter screen can still filter, with minimal impact on the efficiency, thereby reducing the frequency of filter screen cleaning.

[0016] 2. In this utility model, when a large amount of impurities accumulate inside the first filter screen after prolonged use, affecting the air intake efficiency, the fastening hook rod and hook block can be separated to complete the separation of the top cover from the furnace body. After removing the old first filter screen and placing the new first filter screen inside the furnace body, the connecting ring is placed on top of the limiting ring, the top cover is closed, and the squeezing ring squeezes the connecting ring to squeeze and limit the first filter screen. At the same time, the sealing ring fills the gap between the connecting ring and the outside, thereby achieving a more convenient effect when cleaning the filter screen. Attached Figure Description

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a CO catalytic combustion furnace slag removal device, including a furnace body 1, an exhaust pipe 3 fixed through the bottom of the furnace body 1, a top cover 2 hinged to the top of the furnace body 1, an air inlet pipe 4 fixed through the top of the top cover 2, a protective cover 8 fixed through the middle of one side of the outer wall of the furnace body 1, a micro motor 9 fixed to one side of the protective cover 8, the power output end of the micro motor 9 movably passing through the outer wall of the protective cover 8 and fixed with a transmission rod 10, a slider 11 fixed to one end of one side of the transmission rod 10, an impact block 13 slidably connected through the outer wall of the furnace body 1 near the protective cover 8, a movable sleeve rod 12 fixed to one side of the impact block 13, and a first filter screen 14 placed inside the furnace body 1.

[0028] The slider 11 is slidably connected to the movable sleeve rod 12. The protective cover 8 is hollow. The transmission rod 10, slider 11, movable sleeve rod 12 and impact block 13 are all located inside the protective cover 8. The protective cover 8 protects the internal components and prevents the gas inside the furnace body 1 from diffusing to the outside. The micro motor 9 drives the transmission rod 10 to rotate, which in turn drives the slider 11 to slide inside the movable sleeve rod 12. This causes the movable sleeve rod 12 to drive the impact block 13 to move laterally back and forth. The impact block 13 intermittently impacts the first filter screen 14, causing the first filter screen 14 to shake and shake off some of the impurities blocking the mesh.

[0029] The first filter screen 14 is fixed with a connecting ring 15 at the top, and a limiting ring 17 is fixed at the top of the inner wall of the furnace body 1. The connecting ring 15 is located at the top of the limiting ring 17. When the first filter screen 14 is disassembled or assembled, the first filter screen 14 is placed directly inside the furnace body 1, and the connecting ring 15 rests on the top of the limiting ring 17.

[0030] The first filter 14 has a second filter 16 fixed at the bottom center. Both the outer walls of the first filter 14 and the second filter 16 have ventilation holes. The vertical cross-section of the second filter 16 is an isosceles trapezoidal shape. When in use, gas enters through the air inlet pipe 4 and is filtered by the first filter 14 and the second filter 16. The second filter 16 is located inside the first filter 14 and protrudes. Even when there are impurities at the bottom of the first filter 14, the second filter 16 can still filter them.

[0031] The distance between one side of the impact block 13 and the outer wall of the first filter screen 14 is less than the length of the transmission rod 10, and one side of the impact block 13 is used in conjunction with the middle of the first filter screen 14, so that when the micro motor 9 is working, it can drive the impact block 13 to intermittently impact the first filter screen 14.

[0032] The furnace body 1 has a fastening hook rod 5 on the top of its outer wall and a hook block 6 fixed on the bottom of its outer wall. The fastening hook rod 5 and the hook block 6 are used together. When it is necessary to disassemble or assemble the first filter screen, the fastening hook rod 5 and the hook block 6 can be connected and separated to complete the connection and separation of the upper cover 2 and the furnace body 1.

[0033] The bottom of the upper cover 2 is fixed with a compression ring 7. Both the bottom of the compression ring 7 and the bottom of the upper cover 2 are fixed with sealing rings. When installing the first filter screen 14, after the first filter screen 14 is placed inside the furnace body, the upper cover 2 is closed. The compression ring 7 compresses the connecting ring 15 to compress and limit the first filter screen 14. At the same time, the sealing ring fills the gap between the connecting ring 15 and the outside.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, gas is first injected into the inlet pipe 4 during catalysis. The gas is filtered through the first filter screen 14 and the second filter screen 16. The internal components are protected by the protective cover 8, which also prevents the gas inside the furnace body 1 from diffusing to the outside. Then, the micro motor 9 is started, which drives the transmission rod 10 to rotate, thereby causing the slider 11 to slide inside the moving sleeve rod 12. This causes the moving sleeve rod 12 to drive the impact block 13 to move laterally back and forth. The impact block 13 intermittently impacts the first filter screen 14, causing the first filter screen 14 to shake and dislodge some of the impurities blocking the mesh. The second filter screen 16 is then... The second filter 16 protrudes inside the first filter screen 14. When impurities are located at the bottom of the first filter screen 14, the second filter screen 16 can still filter, with little impact on the efficiency. After long-term use, when a large amount of impurities accumulate inside the first filter screen 14, affecting the air intake efficiency, the fastening hook rod 5 and hook block 6 can be separated to complete the separation of the top cover 2 and the furnace body 1. After removing the old first filter screen 14 and placing the new first filter screen 14 inside the furnace body, the connecting ring 15 rests on the top of the limiting ring 17, and the top cover 2 is closed. The squeezing ring 7 squeezes the connecting ring 15 to squeeze and limit the first filter screen 14, while the sealing ring fills the gap between the connecting ring 15 and the outside.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
