Description

Technical Field

[0001] The invention relates to the technical field of ceramic production and processing, and in particular to a ceramic processing gas purification device. Background Art

[0002] In the ceramic production process, the gas emissions from kiln exhaust, raw material preparation dust, and molding, sintering and other links have always been a problem that has plagued the green development of the ceramic industry. These exhaust gases not only contain harmful substances such as sulfur dioxide, nitrogen oxides, and particulate matter, but may also contain volatile organic compounds (VOCs), which pose a potential threat to the environment and human health. Therefore, the research and development and application of gas purification and treatment equipment in the ceramic industry have become the key to promoting the green transformation of the industry and achieving sustainable development. In the existing technology, the filter material cannot be fully utilized when filtering the gas, and it is easy to accumulate at the air outlet of the filter, thus affecting the gas circulation speed and gas filtration efficiency.

[0003] A Chinese invention patent with announcement number CN 118286802 A discloses a ceramic gas purification device for green ceramic production and processing, which relates to the field of ceramic gas purification technology, including a kiln and a gas circulation mechanism, wherein the gas circulation mechanism is installed on the kiln; the present invention is used in conjunction with a kiln, and during the door opening and cooling stage, the gas in the kiln is subjected to low-impact replacement and filtration, so that harmful substances in the kiln are discharged, thereby avoiding the continuous emission of harmful gases during the cooling stage and causing serious impact on the staff, and the present application avoids the adverse effects of excessive cooling on ceramics by circulating gas, thereby ensuring the forming rate of ceramics, and the present application automatically replaces the filter block material, removes the filter blocks with severe filtration, and adds a new filter block at the end, so that each filter block is used evenly, fully utilizing the material, and ensuring the filtering effect and gas circulation speed. With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the exhaust gas contains harmful substances such as sulfur dioxide, nitrogen oxides, dust, particulate matter, etc. It is difficult to filter a variety of harmful substances in a targeted manner by filtering only through filter blocks, and the filtering effect is poor, so multi-layer filtration is required. In addition, when the gas is recycled, the temperature in the kiln is relatively high, so the circulating gas also has a high temperature. The circulating gas is not properly temperature-controlled, and the high-temperature gas continues to be input into the kiln, which greatly reduces the gas circulation effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Among them, after the ceramics are fired in the kiln 1, the ceramics inside the kiln 1 need to be gradually cooled down. The cooling of ceramics is a complicated process. Depending on the different stages of the ceramic cooling, sometimes rapid cooling is required, and sometimes slow cooling is required. Therefore, the cooling speed is also different. When the device is used, the gas in the kiln 1 first enters the exhaust box 2 for preliminary cooling. The temperature of the cooled gas can be monitored in real time through the temperature sensor 25 inside the exhaust box 2.

The air inside the exhaust box 2 is output through the pipe 8 at the upper end. Radiators 23 are installed on both sides of the exhaust box 2. A heat conductor 24 is provided inside the exhaust box 2. Both ends of the heat conductor 24 pass through both sides of the exhaust box 2 and are respectively connected to two radiators 23.

[0047] The gas in the kiln 1 enters the exhaust box 2 through the exhaust port 21, and is opened through the exhaust valve 22 when cooling is required. The gas first enters the bottom of the exhaust box 2, and is moved to the upper pipe 8 through the operation of the exhaust fan 5. The gas just discharged from the kiln 1 has a high temperature. The high-temperature gas exchanges heat with the heat-conducting member 24 inside the exhaust box 2 to reduce the gas temperature. The heat-conducting member 24 absorbs heat and is cooled through the radiators 23 on both sides of the exhaust box 2.

[0049] The particle filter assembly 33 and the gas filter assembly 34 are both controlled to rotate by a rotating mechanism 37 .

[0050] Among them, the filtering mechanism 3 can purify dust particles and harmful gases. The gas discharged from the kiln 1 is initially cooled through the exhaust box 2 and then input into the particle filter 332 from the upper cover 38 of the particle filter cartridge 31 through the pipe 8. The particle filter 332 is in the shape of a circular tube. The gas passes through the particle filter 332 and enters the particle filter cartridge 31. The dust particles in the gas can be filtered through the particle filter 332. The gas then enters the gas filter cartridge 32 through the connecting bridge 35, and then the gas passes through the gas filter 342 and enters the circular tube-shaped gas filter 342. The harmful gas can be adsorbed through the gas filter 342, and finally output through the upper cover 38 at the upper end of the gas filter cartridge 32. When filtering the gas, the particle is driven by the rotating mechanism 37. The filter assembly 33 and the gas filter assembly 34 rotate, so that the gas can enter or be discharged from the surroundings of the particle filter 332 and the gas filter 342, and the filtered material will not be accumulated in the local area of ​​the particle filter 332 and the gas filter 342. The particle filter 332 and the gas filter 342 can be fully utilized, thereby improving the gas filtering efficiency. The particle filter assembly 33 and the gas filter assembly 34 are both threadedly connected to the turntable 373 through the connecting ring 3313. The particle filter assembly 33 and the gas filter assembly 34 can be disassembled by opening the upper cover 38. After the particle filter assembly 33 and the gas filter assembly 34 are disassembled, the particle filter 332 and the gas filter 34 can be removed from the support column 3312, which can facilitate subsequent maintenance or replacement.

[0051] The rotating mechanism 37 includes a rotating tube 371 rotatably installed at the bottom of the particulate filter cartridge 31 and a rotating shaft 372 rotatably installed at the bottom of the gas filter cartridge 32. A turntable 373 is provided near the upper end of the rotating tube 371 and the rotating shaft 372. A pulley 1 374 is fixedly installed near the lower end of the rotating tube 371. A pulley 2 375 is provided at the bottom of the rotating shaft 372. The rotating mechanism 37 also includes a motor 1 376 for providing power. Two active pulleys 377 are provided at the output end of the motor 1 376. The pulley 1 374 and the pulley 2 375 are connected to the two active pulleys 377 through belts 378 respectively.

[0052] Among them, the motor 1 376 drives two active pulleys 377 to rotate, and drives the pulley 1 374 and the pulley 2 375 to rotate through two belts 378, so that the rotating tube 371 and the rotating shaft 372 rotate, and the turntable 373 rotates, thereby rotating the particulate matter filter component 33 and the gas filter component 34.

[0053] The temperature regulating mechanism 7 includes an air inlet pipe 71 and an air exhaust pipe 72 arranged at the bottom of the temperature regulating box 4. The air inlet pipe 71 and the air exhaust pipe 72 are opened or closed at the same time by a switch valve 73. The switch valve 73 is controlled to rotate by a motor 3 74. An air inlet fan 75 is installed inside the air inlet pipe 71, and an air exhaust fan 76 is installed inside the air exhaust pipe 72. The air inlet fan 75 and the air exhaust fan 76 are located outside the switch valve 73. A flow stabilizing baffle 77 is provided inside the temperature regulating box 4, and a through hole 1 78 is provided in the middle of the flow stabilizing baffle 77.

[0054] The switch valve 73 includes a valve shaft 731, on which two valve balls 732 are provided. A ball cavity 79 is provided inside the air inlet pipe 71 and the exhaust pipe 72. The valve ball 732 is located inside the ball cavity 79 and is rotatably connected to the ball cavity 79. Two through holes 733 in the same direction are provided on the two valve balls 732. When the two through holes 733 are coaxial with the air inlet pipe 71 and the exhaust pipe 72, respectively, the switch valve 73 is opened.

[0055] The filter mechanism 3 filters the gas and then transmits it to the temperature control box 4 through the upper cover 38 at the upper end of the gas filter cartridge 32 through the pipeline 8. The temperature of the gas entering the temperature control box 4 needs to be adjusted according to the different stages of the ceramic cooling process, so that the gas can be blown into the kiln 1 at a reasonable temperature. After the gas enters the temperature control box 4, the gas still has a relatively high temperature. The motor 3 74 drives the valve shaft 731 to rotate, so that the two valve balls 732 on the valve shaft 731 rotate in the two ball cavities 79, so that The through holes 733 on the two valve balls 732 are respectively coaxial with the air inlet pipe 71 and the exhaust pipe 72, so the switch valve 73 is opened, and the gas in the temperature control box 4 is partially discharged through the exhaust fan 76, and the air inlet fan 75 inputs external air into the temperature control box 4, which can quickly ventilate the gas in the temperature control box 4, so that the gas temperature in the temperature control box 4 is quickly reduced, and then the temperature-controlled gas is transported to the air inlet box 6 through the exhaust fan 5, which can be used for the rapid cooling stage inside the kiln 1.

[0056] The connecting bridge 35 is opened or closed by a back-blowing mechanism 36. The back-blowing mechanism 36 includes a cylindrical cavity 361 located inside the connecting bridge 35. A rotating column 362 is rotatably installed inside the cylindrical cavity 361. The rotating column 362 is controlled to rotate by a back-blowing motor 363. A through groove 364 is opened in the middle of the rotating column 362. When the through groove 364 is in the same direction as the connecting bridge 35, the particle filter cartridge 31 and the gas filter cartridge 32 are connected through the through groove 364. An exhaust pipe 39 is provided on one side of the gas filter cartridge 32. An air valve 1 310 is provided between the exhaust pipe 39 and the gas filter cartridge 32. An exhaust hood 311 is connected to the output end of the exhaust pipe 39 by threads, and a number of air holes are evenly distributed at the output port of the exhaust hood 311. A gas filter 2 312 is provided inside the exhaust hood 311. An air valve 2 313 is provided between the rotating tube 371 and the particle filter cartridge 31. The bottom of the rotating tube 371 is also connected to the exhaust hood 311 by threads, and a particle filter 2 314 is provided inside the exhaust hood 311.

[0057] Among them, after the ceramic is cooled and the gas is purified, more harmful substances such as dust and particulate matter will be adsorbed on the particle filter 332, and more harmful substances such as sulfur dioxide and nitrogen oxides will be adsorbed on the gas filter 342. These harmful substances can be cleaned by the back-blowing mechanism 36, thereby increasing the service time. When the gas in the kiln 1 is purified, the gas valve 1 310 and the gas valve 2 313 are both in a closed state. After the purification is completed, the gas valve 1 310 is opened, and the back-blowing motor 363 drives the rotating column 362 to rotate, so that the through groove 364 on the rotating column 362 rotates 90 degrees, so that the through groove 364 is closed, and the connecting bridge 35 is closed, so that the gas filter cartridge 32 and the particle filter cartridge 31 are no longer connected, and then the exhaust fan 5 is reversed to transport the gas in the kiln 1 through the upper cover 38 to the inside of the gas filter 1 342, and the harmful gas adsorbed on the gas filter 1 342 is back-blown. At this time, the gas in the kiln 1 still has residual temperature, which can increase the activity of the gas. The harmful gas leaves the gas filter 1 342 and enters the exhaust hood 311 through the exhaust pipe 39, and is adsorbed by the gas filter 2 312. The exhaust hood 311 is connected to the exhaust pipe 39 by a thread, and can be disassembled by rotating the exhaust hood 311, so that the gas filter 2 312 is convenient to replace. After the back-blowing of the gas filter 1 342 is completed, the air valve 1 310 is closed, the air valve 2 313 is opened, and the back-blowing motor 363 drives the rotating column 362 to rotate 90 degrees again, so that the through groove 364 and the connecting bridge 35 are in the same direction, so that the particle filter cartridge 31 and the gas filter cartridge 32 are connected. At this time, the gas enters the gas filter cartridge 32 through the through groove 364 and back-blown the particle filter 1 332. The dust particles adsorbed on the particle filter 1 332 enter the exhaust hood 311 through the rotating tube 371 and are adsorbed by the particle filter 2 314. The exhaust hood 311 can be disassembled by rotating the exhaust hood 311, so that the particle filter 2 314 is convenient to replace.
