Description

Technical Field

[0001] The invention relates to the technical field of waste gas filtering, and in particular to a waste gas filtering device for heat-treating bearing steel balls. Background Art

[0002] A large amount of oily waste gas and smoke will be generated during the heat treatment of bearing steel balls. These waste gases not only pollute the environment, but also may have serious impacts on the health of workers. These waste gases mainly come from the heating, insulation and cooling stages, which may contain harmful substances such as oil fume particles, non-methane total hydrocarbons, nitrogen oxides, etc.

[0003] In the prior art, the heat treatment exhaust gas is filtered multiple times through various filtering methods. However, when the existing device filters pollutants such as particulate matter and oil mist in the exhaust gas, the filtering effect of the device deteriorates after long-term use, and the filtering structure needs to be cleaned multiple times before it can be used normally for a long time.

[0004] For example, in the exhaust gas filtering equipment provided by CN118142275B, when the dust on the filter cartridge accumulates to a certain extent, it can be cleaned without stopping the machine, thereby ensuring the continuous and efficient operation of the exhaust gas filtering process, which not only greatly improves the work efficiency and reduces the production loss caused by stopping the machine for cleaning, but also effectively extends the service life of the filter cartridge and reduces the maintenance cost; after the filter cartridge filters the exhaust gas for a long time, the staff can control multiple filter cartridges to rotate synchronously, and at the same time control the scraper to move up and down. As the filter cartridge rotates, the scraper scrapes off the dust particles attached to the inner surface of the filter cartridge, and the scraped dust particles are discharged to the bottom through the sewage outlet on the support plate under the action of their own gravity. When the dust particles below accumulate to a certain extent, the staff can control the scraper to move downward, so that the scraper extends into the sewage outlet and seals the sewage outlet, thereby isolating the cleaned dust particles from the filter holes on the filter cartridge.

[0005] It has major disadvantages: a large amount of dust attached to the inside of the filter cartridge is cleaned by rotating the filter cartridge and moving the scraper up and down; the scraper can only perform linear scraping along the inner wall of the filter cartridge, and the cleaning efficiency is limited by the moving speed and scraping force of the scraper, and it may not be possible to completely remove all dust particles attached to the inner wall of the filter cartridge; if the scraper rises and falls too quickly, the cleaning effect on the filter cartridge is poor, and it cannot be completely cleaned, and a spiral uncleaned part will remain in the filter cartridge. Summary of the invention

[0006] The embodiment of the present application provides a bearing steel ball heat treatment exhaust gas filtration device, which solves the problem in the prior art that a large amount of dust attached to the inside of the filter cartridge is cleaned by rotating the filter cartridge and moving the scraper up and down; the scraper can only perform linear scraping along the inner wall of the filter cartridge, and the cleaning efficiency is limited by the moving speed and scraping force of the scraper, and it may not be possible to completely remove all dust particles attached to the inner wall of the filter cartridge; if the scraper rises and falls at a fast speed, the cleaning effect on the filter cartridge is poor, and it cannot be completely cleaned, and a spiral uncleaned part remains in the filter cartridge, thereby realizing that the scraper is transformed into a cylindrical shape that passes through the top and bottom, and the scraper rises or falls vertically, so that the inner wall of the filter cartridge can be completely cleaned, avoiding the linear scraping of the filter cartridge by the scraper, and the cleaning efficiency is limited by the moving speed of the scraper.

The limiting opening 1 231 has a thread matched with the rotating rod 1 210. The rotating rod 1 210 is rotatably connected in the limiting opening 1 231. The limiting opening 232 is sleeved on the limiting rod 1 290. The scraper 250 is a cylindrical body that penetrates from top to bottom. The axis of the scraper 250 is parallel to the axis of the gas storage cylinder 110. The rotating block 230 is located in the inner circle of the scraper 250. A connecting rod 240 is fixed between the rotating block 230 and the scraper 250. The sealing cover 260 is located outside the cavity of the gas storage cylinder 110; The rotating block 1 230 is located in the filter cartridge 140 . The rotating block 1 230 , the limiting opening 1 231 and the limiting opening 232 are all cylindrical, and their axes are parallel to the axis of the air storage cartridge 110 . The maximum diameter of the sealing cover 260 is consistent with the inner diameter of the scraper 250; The connecting rods 240 are fixed in plurality between the rotating block 230 and the scraper 250 and are evenly spaced and distributed in a ring shape; The filter assembly 100 further includes a support leg 120, a filter hole 141, a storage cover 150, an air inlet pipe 160, an air outlet pipe 170 and a filter screen 180; There are multiple supporting legs 120, which are evenly spaced and fixed on the side wall of the gas storage cylinder 110. The number of storage covers 150 is consistent with the number of filter cartridges 140, and they correspond one to one. The storage covers 150 are threadedly connected to the lower end of the filter cartridge 140. The air inlet pipe 160 is fixed to one side of the air inlet cylinder 130 and communicates with the internal cavity of the air inlet cylinder 130. The air outlet pipe 170 is fixed to one side of the air storage cylinder 110 and communicates with the internal cavity of the air storage cylinder 110. The filter cartridge 140 has filter holes 141 on its surface. There are multiple filter holes 141 that are evenly spaced. The number of the filter nets 180 is consistent with the number of the filter holes 141 and they correspond one to one. The filter nets 180 are fixed in the filter holes 141. The filter hole 141 is located in the gas storage cylinder 110, and the mesh diameter of the filter 180 is smaller than the diameter of impurities in the exhaust gas; The cleaning assembly 200 also includes a motor 220; The motor 220 is fixed on the upper side of the air intake cylinder 130 , the output end of the motor 220 is fixed on the rotating rod 210 , and the rotation axis of the motor 220 is parallel to the axis of the air storage cylinder 110 .

[0024] When in use, the exhaust gas enters the air intake cylinder 130 through the air intake pipe 160, and enters the interior of the filter cylinder 140, is filtered by the filter screen 180 of the filter cylinder 140, and the filtered gas enters the air storage cylinder 110 and is discharged through the air outlet pipe 170. When the filter screen 180 is blocked due to long-term use, the motor 220 is started to drive the rotating rod 210 to rotate. The rotating rod 210 rotating in different directions controls the rotating block 230 to rotate up or down through the threads on the surface. During the descent of the filter cartridge 140, the dust attached to the inner wall of the filter cartridge 140 is scraped off by the scraper 250, and the scraped dust falls into the storage cover 150 due to its own gravity. The inner wall of the filter cartridge 140 is completely cleaned by the repeated rise and fall of the scraper 250. After a period of use, when the storage cover 150 is full of dust, the scraper 250 is dropped to the lowest position, and the scraper 250 and the sealing cover 260 together block the lower end of the filter cartridge 140, and the dust in the storage cover 150 is cleaned by manually disassembling the storage cover 150.

[0025] Compared with the prior art, the scraper 250 is changed into a cylindrical shape that passes through from top to bottom, and the scraper 250 rises or falls vertically, so that the inner wall of the filter cartridge 140 can be completely cleaned, avoiding the scraper 250 performing linear scraping on the filter cartridge 140, and the cleaning efficiency is limited by the moving speed of the scraper 250. During the cleaning process, the scraper 250 rises and falls too fast, and the cleaning effect on the filter cartridge 140 is poor, and it cannot be completely cleaned.

[0026] Embodiment 2: During the use of the device, the scraper 250 is always in contact with the inner wall of the filter cartridge 140. After a long period of use, dust accumulates on both ends of the scraper 250. When the scraper 250 is rising, the impurities accumulated below the scraper 250 will adhere to the part that has been scraped by the scraper 250. When the scraper 250 is descending, the impurities accumulated above the scraper 250 will adhere to the part that has been scraped by the scraper 250, resulting in a poor cleaning effect. Based on this, the solution of embodiment 1 is improved, such as Figure 9-10 As shown: The cleaning assembly 200 further includes an air bag 270; The airbag 1 270 is annular and is fixed to the outer ring of the scraper 250; It also includes an air supply assembly 300, the number of the air supply assembly 300 is consistent with the number of the cleaning assembly 200, and they correspond one to one; The air supply assembly 300 includes a winding component 1, and the winding component 1 includes a winder 310, a connecting pipe 320 and an air pump 1 330; The reel 310 is fixed on the upper side of the air inlet cylinder 130, the air pump 1 330 is fixed on one side of the reel 310, the connecting pipe 320 is reeled in the reel 310, one end of the connecting pipe 320 is connected with the output end of the air pump 1 330, one end of the connecting pipe 320 away from the air pump 1 330 passes through the shell of the air inlet cylinder 130 and is fixed on the inner circle of the scraper 250, and the connecting pipe 320 is connected with the air bag 1 270; The connecting pipe 320 is sealed and slidably connected to the housing of the air intake cylinder 130; The reel 310 is an automatic wire reel and is a prior art, so it will not be described in detail here.

[0027] When the inner wall of the filter cartridge 140 needs to be cleaned, the scraper 250 is located at the top of the filter cartridge 140, and the airbag 270 is inflated by the air pump 330 to contact the inner wall of the filter cartridge 140. The height of the scraper 250 is continuously lowered by the rotation of the motor 220. During the lowering process, the airbag 270 wipes and scrapes off the attached dust. At the same time, when used for a long time, the airbag 270 can be continuously expanded and contracted to generate vibration to shake off the dust attached to the surface. , improving the cleaning effect next time; when the scraper 250 needs to be raised, the airbag 270 retracts and does not fit the inner wall of the filter cartridge 140. When it reaches the highest position in the filter cartridge 140, the airbag 270 expands again, and the cleaning is performed reciprocatingly. When the storage cover 150 needs to be removed, the airbag 270 expands to improve the sealing performance; when the height of the airbag 270 rises or falls, the connecting tube 320 for air supply is automatically rolled up or released by the winder 310.

[0028] An airbag 270 is fixed on the outside of the scraper 250. After expansion, the airbag 270 fits with the filter cartridge 140. During the descent, the airbag 270 fits and cleans the inner wall of the filter cartridge 140, thereby improving the degree of fit, reducing the generation of gaps, and improving the cleaning effect. At the same time, the airbag 270 is continuously expanded and contracted to generate vibrations, thereby shaking off dust attached to the surface and improving the next cleaning effect. When the storage cover 150 is removed for cleaning, the airbag 270 expands to improve the sealing performance and prevent unfiltered exhaust gas from being ejected.

[0029] Embodiment 3: When the second embodiment is in use, the inner wall of the filter cartridge 140 is cleaned by the expansion of the airbag 1 270. However, the cleaning efficiency is poor during use. The device can be improved to improve the cleaning effect. Based on this, the solution of the second embodiment is improved, such as Figure 11-Figure 12 As shown: The cleaning assembly 200 further includes a second airbag 280, which is annular and fixed to the outer ring of the scraper 250. The second airbag 280 is located below the first airbag 270. The air supply assembly 300 further includes a winding member 2, and the winding member 2 has the same structure as the winding member 1; The reel 310 in the reel-up member 2 is fixed to the upper side of the air inlet cylinder 130, the air pump 1 330 is fixed to one side of the reel 310, the connecting pipe 320 is reeled in the reel 310, one end of the connecting pipe 320 is connected to the output end of the air pump 1 330, the end of the connecting pipe 320 away from the air pump 1 330 passes through the housing of the air inlet cylinder 130 and is fixed to the inner circle of the scraper 250, and the connecting pipe 320 is connected to the air bag 2 280; The connecting pipe 320 in the second winding member is sealed and slidably connected to the housing of the air inlet cylinder 130 .

[0030] When the inner wall of the filter cartridge 140 needs to be cleaned, the scraper 250 is located at the top of the filter cartridge 140, and the airbag 1 270 is inflated by the air pump 1 330 to contact the inner wall of the filter cartridge 140. The height of the scraper 250 is continuously lowered by the rotation of the motor 1 220. During the lowering process, the dust attached is scraped off by the airbag 1 270, and the airbag 2 280 is continuously inflated and deflated, so that the airbag 2 280 intermittently contacts the filter cartridge 140, hits the filter cartridge 140, and causes the filter cartridge 140 to vibrate. The vibration makes the dust attached to the filter cartridge 140 The relatively firm dust on the inner wall is shaken loose, making it easier for airbag 1 270 to wipe and clean. At the same time, when used for a long time, airbag 1 270 and airbag 2 280 can be continuously expanded and contracted to produce vibration, thereby shaking off the dust attached to the surface and improving the cleaning effect. When it is necessary to raise the height of the scraper 250, airbag 1 270 and airbag 2 280 retract together and do not fit the inner wall of the filter cartridge 140. When reaching the highest position in the filter cartridge 140, airbag 1 270 expands again. During the descent, airbag 2 280 expands intermittently, thereby performing a reciprocating cleaning process.

[0031] During the descent of the scraper 250, the continuous expansion and contraction of the airbag 2 280 impacts the filter cartridge 140, causing the filter cartridge 140 to vibrate, thereby loosening the dust firmly attached to the inner wall of the filter cartridge 140, making it easier for the airbag 1 270 above to clean the dust; the cooperation between the airbag 1 270 and the airbag 2 280 improves the cleaning effect of the dust.

[0032] Embodiment 4: When the embodiment 3 is in use, the dust inside the filter cartridge 140 is cleaned by wiping with the airbag 1 270 and impacting with the airbag 2 280. However, during long-term use, a large amount of dust remains in the mesh of the filter screen 180. After being squeezed by the airbag 1 270 and the airbag 2 280, the dust passes through the mesh of the filter screen 180 and enters the air storage cartridge 110, thereby causing the filtering effect to deteriorate. Based on this, the solution of the embodiment 3 is improved, such as Figure 13-Figure 16 As shown: The filter assembly 100 further includes a third opening 113. The gas storage cylinder 110 is provided with a third opening 113, and the third opening 113 has two portions. The auxiliary assembly 400 includes a second rotating rod 410, a second motor 420, a second rotating block 430, a third limiting opening 431, a fourth limiting opening 432, a second connecting rod 440, a lifting ring 450, a second air pump 460, a second limiting rod 470, a resisting airbag 480 and an air delivery pipe 490. The second rotating rod 410 and the second limiting rod 470 are both cylindrical, and the axes of the two are parallel to the axis of the gas storage cylinder 110; The second rotating rod 410 and the second limiting rod 470 are located between the plurality of filter cartridges 140; The two third openings 113 correspond to the second rotating rod 410 and the second limiting rod 470 respectively, and the second rotating rod 410 and the second limiting rod 470 are rotatably connected to the two third openings 113 respectively, and the third opening 113 matched with the second rotating rod 410 has a thread inside; The outer wall of the second rotating rod 410 is threaded, the upper end of the second rotating rod 410 is rotatably connected to the top side of the air inlet cylinder 130, and the lower end of the second rotating rod 410 is rotatably connected to the bottom side of the air storage cylinder 110; The upper end of the second limiting rod 470 is fixed to the top side of the air inlet cylinder 130, and the lower end of the second limiting rod 470 is fixed to the bottom side of the air storage cylinder 110; The second motor 420 is fixed to the upper side of the air inlet cylinder 130, and the output end of the second motor 420 is fixed to the second rotating rod 410. The rotation axis of the second motor 420 is parallel to the axis of the air storage cylinder 110. The second rotating block 430 has a third limiting opening 431 and a fourth limiting opening 432. The second rotating block 430, the third limiting opening 431 and the fourth limiting opening 432 are all cylindrical, and their axes are parallel to the axis of the gas storage cylinder 110. The third limiting opening 431 has a thread that matches the second rotating rod 410. The second rotating rod 410 is rotatably connected in the third limiting opening 431, and the fourth limiting opening 432 is sleeved on the second limiting rod 470; The second rotating block 430 and the lifting ring 450 are both located in the gas storage cylinder 110; The number of the second connecting rod 440, the lifting ring 450, the second air pump 460, the abutting air bag 480 and the air delivery pipe 490 is consistent with the number of the filter cartridge 140, and corresponds one to one; The lifting ring 450 is a cylindrical shape that passes through from top to bottom, and the axis of the lifting ring 450 is parallel to the axis of the air cylinder 110. The lifting ring 450 is sleeved on the filter cylinder 140. The resistance airbag 480 is annular and fixed to the inner ring of the lifting ring 450. The air pump 460 is fixed to the outer wall of the air cylinder 110. The air pipe 490 is located in the air cylinder 110. One end of the air pipe 490 passes through the inner wall of the air cylinder 110 and is connected to the output end of the air pump 460. The end of the air pipe 490 away from the air pump 460 is fixed on the lifting ring 450 and is connected to the resistance airbag 480; the two ends of the connecting rod 440 are respectively fixed on the outer wall of the lifting ring 450 and the outer wall of the rotating block 430.

[0033] When it is necessary to clean the inside of the filter cartridge 140, the scraper 250 is located at the top side of the filter cartridge 140, and the lifting ring 450 is located at the top of the outer side of the filter cartridge 140. When the scraper 250 descends to make the airbag 270 clean the inner wall of the filter cartridge 140, the resistance airbag 480 expands together, and the resistance airbag 480 resists the filter cartridge 140 and gradually presses the filter screen 180 on the filter cartridge 140. The resistance airbag 480 is on the filter screen 180. The protrusion pushes out the dust in the mesh of the filter 180. The pushed out dust can also continuously change the inflation volume of the resistance airbag 480, so that the dust in the mesh of the resistance filter 180 shakes and is wiped and scraped away by the descending airbag 270. During the cleaning process, the lower end of the lifting circle 450 is always 1-2 cm lower than the lower end of the scraper 250. When the inflation volume of the resistance airbag 480 is changed, the resistance airbag 480 always resists the outer wall of the filter tube 140.

[0034] By blocking the filter 180 which is in conflict with the airbag 1 270 and the airbag 2 280 through the conflicting airbag 480, the dust in the filter 180 which is in conflict with the airbag 1 270 and the airbag 2 280 can be prevented from being pushed out, thereby improving the filtering effect with the exhaust gas; at the same time, the conflicting airbag 480 can protrude in the mesh of the filter 180, and push out the dust in the mesh of the filter 180, thereby improving the cleaning effect; at the same time, by continuously changing the inflation amount of the conflicting airbag 480, the vibration cleaning effect on the dust accumulated in the mesh of the filter 180 is improved.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
