Description

Technical Field

[0001] This invention belongs to the technical field of exhaust gas treatment equipment, specifically a honeycomb ceramic exhaust gas treatment and filtration device. Background Technology

[0002] Honeycomb ceramics are a type of porous industrial ceramic. Their internal structure consists of many interconnected parallel channels in a honeycomb shape. These honeycomb units are divided by thin, grid-like partitions. The working principle of a honeycomb ceramic exhaust gas treatment and filtration device is to utilize the porous structure and large specific surface area of ​​the honeycomb ceramics to adsorb, filter, and catalytically transform particulate matter, harmful gases, and other harmful substances in the exhaust gas. When the exhaust gas passes through the honeycomb ceramics, harmful substances such as carbon particles, sulfur oxides, and nitrogen oxides are captured or catalytically transformed into harmless substances by the pore walls of the honeycomb ceramics, thereby achieving the purpose of purifying the exhaust gas.

[0003] When existing honeycomb ceramic exhaust gas treatment and filtration devices are in use, some particles remain on the surface of the honeycomb ceramic filter media as the gas and particulate matter in the exhaust gas pass through, causing accumulation and blockage. This requires the entire device to be disassembled for cleaning, which is a cumbersome and complicated operation. Therefore, improvements are needed. Summary of the Invention

[0011] The sludge collection box is fixedly installed at the bottom of the filter device cylinder and located directly below the cleaning brush. The separation mesh frame is movably installed at the top of the drive fan blade cavity. The shielding component is located inside the filter device cylinder and directly above the sludge collection box.

[0012] Preferably, the shielding assembly includes a shielding plate, a first pneumatic cylinder, and a first pneumatic piston rod;

[0013] The first pneumatic cylinder is disposed inside the filter device cylinder and located on one side of the top of the sludge collection box. The first pneumatic piston rod is movably installed inside the first pneumatic cylinder, and the baffle plate is disposed on one side of the first pneumatic cylinder.

[0014] Preferably, the surface of the filter device cylinder is provided with a pneumatic assembly located outside the vibrating block, the pneumatic assembly including a second pneumatic cylinder, a second pneumatic piston rod and an air pipe;

[0015] The second pneumatic cylinder is disposed on the surface of the filter device cylinder and located at the outer end of the vibrating block. The second pneumatic piston rod is movably installed in the inner cavity of the second pneumatic cylinder, and the inner end of the second pneumatic piston rod is fixedly connected to the outer side of the vibrating block. The second pneumatic cylinder and the first pneumatic cylinder are connected through a vent pipe.

[0016] Preferably, the bottom of the sludge collection box is fixedly connected to a water pipe connection box, which is connected to the other side of the drive fan blade via a three-way water pipe, and one side of the three-way water pipe is movably connected to the other side of the drive fan blade.

[0017] Preferably, a power assembly is provided on one side of the top of the three-way water pipe, the power assembly including a power piston rod, a linkage arm and a connecting frame;

[0018] The power piston rod is movably installed in the inner cavity on one side of the top of the three-way water pipe. The linkage arm is hinged to the outer side of one end of the power piston rod. The connecting frame is set on one side of the movable frame, and one end of the inner side extends to the inner cavity of the air inlet. The inner side of one end of the connecting frame is hinged to the other end of the linkage arm.

[0019] Preferably, a one-way valve assembly is provided on the other side of the inner cavity at the top of the three-way water pipe, the one-way valve assembly including a one-way valve block and a second power spring:

[0020] The one-way valve block is movably installed in the inner cavity on the other side of the top of the three-way water pipe, and the one-way valve block is elastically connected to the inner wall of the three-way water pipe through a second power spring.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The above technical solution, by setting up a drive fan blade and a cleaning brush, will drive the drive fan blade to rotate when the exhaust gas enters the filter cylinder through the air inlet, so as to drive the cleaning brush to rotate synchronously. This allows the brush bristles to continuously clean the surface of the honeycomb ceramic filter block, thus effectively clearing the residual particles from the honeycomb ceramic filter block and achieving rapid cleaning of one side of the honeycomb ceramic filter block. This replaces the existing disassembly cleaning method and is more convenient and faster.

[0023] This invention, by setting a driven tooth block and a first power spring, allows the teeth on the surface of the driving fan blade to push the teeth on the inner side of the driven tooth block when the fan blade rotates, so as to drive the two driven tooth blocks, the movable frame and the vibrating block to move in opposite directions. At the same time, due to the elastic force of the first power spring, the two driven tooth blocks and the movable frame can be pushed towards each other. When the driven tooth block and the teeth of the driving fan blade mesh, the driven tooth block, the movable frame and the vibrating block can move smoothly towards each other. Finally, the vibrating block impacts the outer side of the cleaning brush, which can quickly shake off the impurities adhering to the surface of the cleaning brush, thus achieving rapid cleaning of particles.

[0024] This invention, by setting up a power piston rod and a linkage arm, allows the two movable frames to move synchronously when they move back and forth in opposite directions. This causes the linkage arm to deflect and pull the power piston rod to move back and forth, creating negative pressure in the three-way water pipe. This pressure draws water from the water pipe connection box to one side of the power piston rod, pushing the water flow to move the one-way valve block to one side. Ultimately, the water flows smoothly through the three-way water pipe, the drive fan blade, and the connecting pipe, before being sprayed out from the cleaning brush. This achieves cleaning while the cleaning brush is sweeping, and the water can be recycled through filtration by the dirt collection component, greatly reducing water waste.

[0035] like Figures 1 to 8As shown, the present invention provides a honeycomb ceramic exhaust gas treatment and filtration device, including a filter device cylinder 1; an air inlet 2, fixedly connected to one side of the filter device cylinder 1, and an exhaust pipe 3 fixedly connected to the other side of the filter device cylinder 1; a honeycomb ceramic filter block 4, disposed in the inner cavity of the filter device cylinder 1, and located on the side near the exhaust pipe 3; a cleaning assembly 5 including a drive fan blade 501, the drive fan blade 501 being movably installed in the inner cavity of the filter device cylinder 1, and located on the side near the air inlet 2, a connecting pipe 502 fixedly connected to one side of the drive fan blade 501, and a cleaning brush 503 fixedly connected to one end of the connecting pipe 502 located on the side near the honeycomb ceramic filter block 4.

[0036] When gas enters the filter cylinder 1 through the air inlet 2, the gas will drive the drive fan blade 501, the connecting pipe 502 and the cleaning brush 503 to rotate as a whole, which will allow the cleaning brush 503 to scrape and clean the particles adhering to one side of the surface of the honeycomb ceramic filter block 4.

[0037] like Figure 5 As shown, the surface of the drive fan blade 501 is provided with a limiting ring block 6 located on the inner wall of the filter device cylinder 1, and the surface of the limiting ring block 6 is movably sleeved with the inner wall of the filter device cylinder 1.

[0038] The above solution is adopted: by setting a limit ring block 6, when the drive fan blade 501 rotates, it can be smoothly driven to rotate under the limiting action of the limit ring block 6.

[0039] like Figure 7 and Figure 8 As shown, the filter device cylinder 1 is equipped with a linkage component 7 located outside the drive fan blade 501. The linkage component 7 includes a driven tooth block 701, a first power spring 702, a movable frame 703, and a vibration block 704.

[0040] Driven tooth block 701 is movably installed inside the filter device cylinder 1 and located outside the drive fan blade 501. Driven tooth block 701 is elastically connected to the inner wall of the filter device cylinder 1 through the first power spring 702. Movable frame 703 is fixedly installed on the outside of the first power spring 702 and its other end extends to the outside of the cleaning brush 503. Vibration block 704 is disposed at one end of movable frame 703.

[0041] The above scheme is adopted: by setting a first power spring 702, when the elastic force of the first power spring 702 is released, it can smoothly push the two driven tooth blocks 701, the movable frame 703 and the vibrating block 704 to move in opposite directions.

[0042] like Figure 8 As shown, the inner side of the driven tooth block 701 meshes with the surface of the driving fan blade 501.

[0043] The above solution is adopted: by setting the driven tooth block 701, when the cleaning brush 503 rotates, the teeth on the surface of the driving fan blade 501 can squeeze and push the inner teeth of the driven tooth block 701, thereby causing the two driven tooth blocks 701 and the movable frame 703 to move in opposite directions as a whole.

[0044] like Figure 4 As shown, the bottom of the filter device cylinder 1 is provided with a dirt collection component 8 located below the cleaning brush 503. The dirt collection component 8 includes a dirt collection box 801, a separation mesh frame 802 and a shielding component 803.

[0045] The sludge collection box 801 is fixedly installed at the bottom of the filter device cylinder 1 and is located directly below the cleaning brush 503. The separation mesh frame 802 is movably installed at the top of the inner cavity of the drive fan blade 501. The shielding assembly 803 is located inside the filter device cylinder 1 and directly above the sludge collection box 801.

[0046] The above solution is adopted: by designing the bottom grid of the separation frame 802, the passing sewage can be filtered, so that the water can be successfully filtered, purified and fall.

[0047] like Figure 4 As shown, the shielding assembly 803 includes a shielding plate 8031, a first pneumatic cylinder 8032, and a first pneumatic piston rod 8033;

[0048] The first pneumatic cylinder 8032 is disposed inside the filter device cylinder 1 and located on one side of the top of the sludge collection box 801. The first pneumatic piston rod 8033 is movably installed inside the first pneumatic cylinder 8032, and the baffle plate 8031 ​​is disposed on one side of the first pneumatic cylinder 8032.

[0049] The above solution is adopted: by setting a first pneumatic piston rod 8033, when the air pressure in the cavity of the first pneumatic cylinder 8032 increases, the first pneumatic piston rod 8033 can be pushed to drive the baffle plate 8031 ​​to move to one side, so as to release the baffle seal on the top of the sludge collection box 801.

[0050] like Figure 7 As shown, the surface of the filter device cylinder 1 is provided with a pneumatic assembly 9 located outside the vibrating block 704. The pneumatic assembly 9 includes a second pneumatic cylinder 901, a second pneumatic piston rod 902, and an air pipe 903.

[0051] The second pneumatic cylinder 901 is disposed on the surface of the filter device cylinder 1 and located at the outer end of the vibrating block 704. The second pneumatic piston rod 902 is movably installed in the inner cavity of the second pneumatic cylinder 901, and the inner end of the second pneumatic piston rod 902 is fixedly connected to the outer side of the vibrating block 704. The second pneumatic cylinder 901 and the first pneumatic cylinder 8032 are connected through the air pipe 903.

[0052] The above scheme is adopted: by setting up a vent pipe 903, when the vibrating block 704 moves in opposite directions, it can push the second pneumatic piston rod 902 to move in opposite directions synchronously, so as to push the gas in the cavity of the second pneumatic cylinder 901 to be introduced into the cavity of the first pneumatic cylinder 8032 through the vent pipe 903.

[0053] like Figure 2 As shown, a water pipe connection box 10 is fixedly connected to the bottom of the sludge collection box 801. The water pipe connection box 10 is connected to the other side of the drive fan blade 501 through a three-way water pipe 11, and one side of the three-way water pipe 11 is movably connected to the other side of the drive fan blade 501.

[0054] The above solution involves setting up a water pipe connection box 10. After the water flows through the separation mesh frame 802 for filtration, the water will fall into the water pipe connection box 10 for storage.

[0055] like Figure 3 As shown, a power assembly 12 is provided on one side of the top of the three-way water pipe 11. The power assembly 12 includes a power piston rod 1201, a linkage arm 1202, and a connecting frame 1203.

[0056] The power piston rod 1201 is movably installed in the inner cavity of one side of the top of the three-way water pipe 11. The linkage arm 1202 is hinged to the outer side of one end of the power piston rod 1201. The connecting frame 1203 is set on one side of the movable frame 703, and one end of the inner side extends to the inner cavity of the air inlet 2. The inner side of one end of the connecting frame 1203 is hinged to the other end of the linkage arm 1202.

[0057] The above solution is adopted: by setting up a power piston rod 1201, when the connecting frame 1203 moves towards or away from each other, the linkage arm 1202 can be deflected to drive the power piston rod 1201 to move back and forth as a whole.

[0058] like Figure 3 As shown, a one-way valve assembly 13 is provided on the other side of the inner cavity at the top of the three-way water pipe 11. The one-way valve assembly 13 includes a one-way valve block 1301 and a second power spring 1302.

[0059] The one-way valve block 1301 is movably installed in the inner cavity on the other side of the top of the three-way water pipe 11. The one-way valve block 1301 is elastically connected to the inner wall of the three-way water pipe 11 through the second power spring 1302.

[0060] The above solution is adopted: by setting a second power spring 1302, when the second power spring 1302 releases its elastic force to push the one-way valve block 1301 to the left, the power piston rod 1201 can block the other end of the three-way water pipe 11 when it moves to the left, so that negative pressure can be generated smoothly at the bottom end.

[0061] Working principle and usage process of this invention:

[0062] First, when the exhaust gas enters the filter cylinder 1 from the intake port 2, the gas will drive the drive fan blade 501, the connecting pipe 502 and the cleaning brush 503 to rotate. At this time, the cleaning brush 503 can continuously clean the surface of one side of the honeycomb ceramic filter block 4. At the same time, due to the meshing relationship between the surface of the drive fan blade 501 and the inner side of the driven tooth block 701, when the drive fan blade 501 rotates and the elastic force of the first power spring 702 works together, it can drive the driven tooth block 701, the movable frame 703 and the vibrating block 704 to move back and forth in opposite directions. The vibrating block 704 will collide and vibrate the outer side of the cleaning brush 503 back and forth, shaking off the particles adhering to the cleaning brush 503.

[0063] Subsequently, the two connecting frames 1203 can move in opposite directions simultaneously via the movable frame 703, causing the linkage arm 1202 to deflect and pull the power piston rod 1201 to move back and forth on one side of the inner cavity of the three-way water pipe 11. When moving to the left, a negative pressure is generated in the inner cavity of the three-way water pipe 11, which draws water from the water pipe connection box 10 and introduces it to one side of the power piston rod 1201. Then, by moving the power piston rod 1201 to the right, the water flow can be pushed to impact the one-way valve block 1301 to the right. The water flow will then enter the cleaning brush 503 through the drive fan blade 501 and the connecting pipe 502, and then spray out, causing the cleaning brush 503 to rotate and sweep while spraying water to clean, thereby improving cleaning efficiency.

[0064] At the same time, when the vibrating block 704 moves in opposite directions, it drives the second pneumatic piston rod 902 to move in opposite directions simultaneously, causing the second pneumatic piston rod 902 to retract into the inner cavity of the second pneumatic cylinder 901. At this time, the gas outside the inner cavity of the second pneumatic cylinder 901 can be pushed into the inner cavity of the first pneumatic cylinder 8032 through the vent pipe 903, which increases the air pressure in the inner cavity of the first pneumatic cylinder 8032 and drives the first pneumatic piston rod 8033 and the baffle plate 8031 ​​to move to one side, releasing the obstruction and sealing of the top of the sludge collection box 801, so that the impurities scraped off by the cleaning brush 503 can fall into the interior of the separation mesh frame 802, while the water will be filtered by the bottom of the separation mesh frame 802 and fall into the water pipe connection box 10, thus realizing the filtration and recycling of water resources.
