Description

During production, pouring is one of the necessary steps, mainly to fill the molten metal material into the mold to form the desired product shape.

Therefore, a smoke filtering and treatment device is required to filter and treat the generated smoke and dust, reduce the impact of smoke and dust on the environment and workers, and ensure the safety and environmental protection of the production process.

[0003] At present, when the smoke filtering and processing device of the casting production process of the cast iron ductile manhole cover is in use, its dust suction pipe is basically fixed during use, resulting in a fixed angle and affecting the smoking angle.

[0019] Compared with the prior art, the present invention provides a smoke filtering and processing device based on the casting production process of cast iron ductile manhole covers, which has the following beneficial effects:

[0020] 1. Through the arrangement of the fixing box, the filter screen and the sealing connection frame and the cooperation of the T-shaped sliding column, the fixing spring, the pushing column and the installation box, the smoke can be pre-filtered before entering the filter body. At the same time, when in use, the fixing spring and the T-shaped sliding column abut and support the clamping column, so that the clamping column is clamped with the limit block, thereby fixing the filter screen. When the clamping column needs to be cleaned and replaced, the T-shaped sliding column is simply pulled to make the pushing column disengage from the support of the clamping column, and then gravity is used to make the inclined clamping column automatically disengage from the clamping block, so that the filter screen can be taken out of the fixing box, and then it can be cleaned or repaired. At the same time, when the filter screen is pulled out of the fixing box, In the process of pulling out, the power generated by pulling out is used to make the cleaning roller rotate and the knocking head knock, and the surface of the filter screen is cleaned at the same time, so that the filter screen is taken out and cleaned at the same time, so that the filter screen can be pre-cleaned in advance before being taken out, thereby saving the time of cleaning the filter screen, reducing the difficulty of cleaning the filter screen, saving operation steps, and at the same time, through pre-filtration of smoke, the cleanliness of the smoke when entering the filter body can be improved, thereby reducing the inspection and replacement frequency of the filter element in the filter body, avoiding the frequent disassembly and fixing of multiple bolts in the existing filter body, and reducing the cost of inspection and maintenance;

[0021] 2. When the reciprocating screw drives the slider and the air inlet pipe to move left and right for position adjustment, the air inlet pipe is made to swing left and right and up and down at the same time by using the extrusion fit between the arc surfaces of the semicircular block 1 and the semicircular block 2, thereby increasing the range of the air inlet pipe to absorb smoke when in use, thereby increasing the effect of smoke absorption, and improving the efficiency of the filter body in filtering smoke and dust in the casting production process of cast iron ductile manhole covers. At the same time, when the air inlet pipe swings up and down, it has a vibrating effect on the internal fixed box, so that the upper part of the fixed box can block the particles in the smoke and dust by vibrating the fixed box up and down. Thereby, the particles adhering to the fixing box are shaken off, the cleanliness of the fixing box is improved during use, the saturation time of the fixing box is prolonged during use, and the maintenance frequency of the fixing box is reduced. Moreover, when the air intake pipe is swinging left and right and up and down, the setting of the air blowing pipe allows the reciprocating screw to drive the slider and the air intake pipe to adjust the left and right positions, and the air flow can be driven by the fan blades and ejected from the air blowing pipe at the same time, thereby increasing the air flow speed around the air intake pipe, and further increasing the heat dissipation efficiency of the air intake pipe, preventing the air intake pipe from overheating due to the smoke absorption process, and improving the durability of the air intake pipe during use.

[0022] 3. When the filter is taken out from the fixed box, the bristles on the cleaning roller are arranged in an umbrella-shaped structure consisting of a straight brush and a plurality of arc-shaped brushes, and are evenly distributed on the outer surface of the cleaning roller, so that when the cleaning roller rotates and cleans the filter, the arc-shaped structure of the arc-shaped brush is squeezed and elastically deformed and easily inserted into the filter hole of the filter. Then, when the filter is pulled out, the umbrella-shaped round edge of the bristles can bring out some impurities in the filter hole. At the same time, the setting of the umbrella-shaped structure also increases the range of the bristles when contacting the filter, thereby increasing the cleaning angle of the bristles, thereby improving the cleaning effect of the cleaning roller when rotating, driving the bristles to clean the filter, making the filter tidier when taken out, thereby further saving the time of the staff for secondary cleaning, saving labor, and reducing the cleaning cost of the staff;

[0023] When the filter screen is removed, the cooperation of the fixing spring and the pushing post can make the spherical surface of the pushing post squeeze the spherical surface of the clamping post, so that the clamping post slides toward the limit block and is engaged, thereby completing the fixing of the filter screen. When the filter screen is removed, the cooperation of the T-shaped sliding post, the pushing post and the clamping post can make the staff first pull the T-shaped sliding post, so that the T-shaped sliding post drives the pushing post to break away from the support of the clamping post, and then under the action of gravity, the clamping post automatically slides in the direction away from the limit block and breaks away from the engagement of the limit block, and then continues to pull the T-shaped sliding post, so that the T-shaped sliding post drives the push-pull frame to move in one direction, thereby the filter screen can be taken out of the fixing box. When the clamping limit of the clamping post and the limit block is released, the T-shaped sliding post and the push-pull frame are pulled in the same direction. The staff only needs to continue to pull the T-shaped sliding post to complete the removal of the filter screen, and the operation is more convenient.

[0024] 5. The U-shaped setting of the air blowing pipe makes the air blowing pipe fit more closely to the arc-shaped surface of the air intake pipe in the prior art, thereby increasing the blowing angle of the air blowing pipe to the air intake pipe when the air blowing pipe is used to cool the air intake pipe, thereby increasing the range of contact between the air flow and the outer surface of the air intake pipe, thereby increasing the cooling effect on the air intake pipe, preventing the air intake pipe from being overheated when in use, and improving the stability of the air intake pipe when in use.

[0048] The pretreatment replacement mechanism 4 includes a fixed box 401, which is fixedly connected to one end of the air inlet pipe 3, and a bellows is fixedly connected to the side of the fixed box 401 away from the air inlet pipe 3. The air inlet pipe 3 is connected to the filter body 1 through the fixed box 401 and the bellows. A filter screen 402 is slidably connected to the inner wall of the fixed box 401, and a sealing connection frame 403 is fixedly connected to one side of the filter screen 402. The sealing connection frame 403 is slidably connected to the fixed box 401, and a push-pull frame 404 is fixedly connected to the side of the sealing connection frame 403 away from the filter screen 402. A rack 405 is fixedly connected to the top of the push-pull frame 404, and the rack 405 is slidably connected to the fixed box 401. Two support blocks 406 are fixedly connected to the fixed box 401 on the side close to the push-pull frame 404. A cleaning roller 407 is rotatably connected between the two support blocks 406. Bristles 4071 are equidistantly fixedly connected to the outer surface of the cleaning roller 407. The bristles 4071 are arranged in an umbrella shape. Both ends of the cleaning roller 407 pass through the support blocks 406. A gear 408 is fixedly connected to the outer surface of the upper end of the support block 406, and the gear 408 is meshed with the rack 405.

[0049] Both ends of the cleaning roller 407 are fixedly connected to a rotating disk 409, and a protrusion 410 is fixedly connected to the outer surface of the rotating disk 409 at an equal distance. Two fixed blocks 411 are fixedly connected to one side of the fixed box 401, and a sliding rod 412 is slidably connected to one side of the fixed block 411. The sliding rod 412 is arranged in an arc shape near the rotating disk 409. A connecting rod 414 is fixedly connected between the sliding rods 412. Two tensioning springs 413 are fixedly connected between the fixed blocks 411 and the connecting rod 414. The tensioning springs 413 are sleeved with the sliding rod 412. The connecting rod 414 is fixedly connected at an equal distance near the side of the sealing connecting frame 403.

[0050] Among them: the side close to the clamping column 421 and the pushing column 418 is set to a spherical shape. Through the spherical setting, the spherical surface of the pushing column 418 can squeeze the spherical surface of the clamping column 421, driving the clamping column 421 to be plugged into the limit block 420, and the protrusion 410 and the sliding rod 412 are set to an arc shape near one end. When the protrusion 410 rotates, the sliding rod 412 can be driven to slide through the arc surface squeezing.

[0051] In the prior art, the smoke filtering and processing device frequently absorbs and filters the smoke in the workshop, resulting in a high saturation rate of the filter element inside it, so that the filter element inside it needs to be replaced frequently. In addition, since the smoke filtering and processing device needs to remove and fix multiple bolts each time it is disassembled, it is inconvenient to replace the filter element inside it each time, which wastes a lot of time and has a high maintenance cost. Compared with the prior art, in the implementation of this embodiment, when the smoke passes through the fixing box 401, some impurities in the smoke will be blocked by the fixing box 401, so that the smoke entering the filter body 1 is cleaner, thereby reducing the saturation rate of the filter element in the filter body 1, thereby reducing the frequency of disassembly and maintenance of the filter element in the filter body 1, and the fixing and disassembly of the filter 402 can be completed by simply pulling, the operation is simple and convenient, and the time for disassembling the filter 402 is saved.

[0052] For further examples, please refer to Figures 9 to 12 As shown:

[0053] The angle adjustment mechanism 5 includes a collecting box 501, a mounting groove is provided at the bottom of the inner cavity of the fixing box 401, the collecting box 501 is clamped at the bottom of the mounting groove, an inclined plate 502 is fixedly connected in the mounting groove, a mounting plate 503 is fixedly connected to one side of the filter body 1, a driving motor 504 is fixedly connected to the upper surface of the mounting plate 503, two supporting seats 506 are fixedly connected to the upper surface of the mounting plate 503, a reciprocating screw rod 505 is fixedly connected to the output end of the driving motor 504, the reciprocating screw rod 505 is rotatably connected with the supporting seat 506, a slider 507 is threadedly sleeved on the outer surface of the reciprocating screw rod 505, the slider 507 is slidably connected to the mounting plate 503, a U-shaped block 508 is slidably connected to the top of the slider 507, the top of the U-shaped block 508 is fixedly connected to the intake pipe 3, and the bottom of the U-shaped block 508 A semicircular block 509 is symmetrically fixedly connected to the upper surface of the mounting plate 503, and a semicircular block 2 510 is evenly fixedly connected to the upper surface of the mounting plate 503. A connecting shaft 511 is fixedly connected to one end of the reciprocating screw rod 505. The connecting shaft 511 is rotatably connected to one of the support seats 506. A fan blade 513 is fixedly connected to one end of the connecting shaft 511. An air cylinder 512 is fixedly connected to the upper surface of the mounting plate 503. The fan blade 513 is located inside the air cylinder 512. A connecting pipe 514 is fixedly connected to one end of the air cylinder 512. An air pipe 515 is fixedly connected to the end of the connecting pipe 514 away from the air cylinder 512. The air pipe 515 is fixedly connected to the mounting plate 503, and an air blowing head is fixedly connected to the outer surface of the air pipe 515 at an equal distance. The air pipe 515 is arranged in a U shape, and the air pipe 515 is located below the air inlet pipe 3.

[0054] Wherein: the arrangement of the semicircular block 1 509 and the semicircular block 2 510 enables the semicircular block 1 509 to move upwards through the squeezing of the circular surface of the semicircular block 2 510 when the semicircular block 1 509 moves.

[0055] In the prior art, when the smoke filtering and processing device is in use during the casting and production process of cast iron ductile manhole covers, its dust suction pipe is basically fixed during use, resulting in a fixed angle and affecting the inhalation angle. When the smoke generated increases and the smoke range becomes larger, the dust suction pipe will affect the effect of smoke absorption due to its limited absorption range. Compared with the prior art, the implementation of this embodiment allows the air intake pipe 3 to swing left and right and up and down at the same time, thereby increasing the range of the air intake pipe 3 absorbing smoke when in use, thereby increasing the effect of smoke absorption and improving the efficiency of the filter body 1 in filtering the smoke during the casting and production process of cast iron ductile manhole covers.

[0056] Everything in the above example works like this:

[0057] In the initial state: the fixed spring 417 is in a normal state, at this time, the T-shaped sliding column 416 is supported by the fixed spring 417, so that the push column 418 limits the clamping column 421, so that the clamping column 421 and the limit block 420 are in a plug-in state. At this time, when the push-pull frame 404 is pulled, the push-pull frame 404 cannot be pulled due to the direct plug-in limit of the limit block 420 and the clamping column 421.

[0058] The following is the working process of the angle adjustment mechanism 5 for adjusting the angle of the intake pipe 3:

[0059] When the filter body 1 is in use, if there is a lot of smoke and dust in the workshop and the distribution range is wide, the drive motor 504 can be started, and the output end of the drive motor 504 rotates to drive the reciprocating screw rod 505 to rotate. Since the slider 507 is threadedly connected to the reciprocating screw rod 505, and the slider 507 is slidably connected to the mounting plate 503, the rotation of the reciprocating screw rod 505 can drive the slider 507 to slide left and right, thereby driving the U-shaped block 508 and the air inlet pipe 3 to move left and right. Then, when the U-shaped block 508 moves left and right, it will drive the semicircular block 509 to move left and right at the same time, so that the semicircular The U-shaped block 1 509 will approach the semicircular block 2 510 during the movement, and then the semicircular block 2 510 will squeeze the semicircular block 1 509, so that the semicircular block 1 509 and the U-shaped block 508 will jump up and down, thereby driving the air intake pipe 3 to swing up and down, and the bellows will bend and twist, so that the air intake pipe 3 can complete the left and right reciprocating movement and the up and down reciprocating movement at the same time when in use, thereby increasing the range of the air intake pipe 3 when absorbing smoke, increasing the suction effect of the air intake pipe 3 on the smoke, and at the same time improving the purification efficiency of the filter body 1 on the smoke;

[0060] The filter screen 402 in the fixed box 401 is then pulled back and forth to prevent the impurities from being caught by the filter screen 402. The filter screen 402 in the fixed box 401 is then pulled back and forth to prevent the impurities from being caught by the filter screen 402.

[0061] Furthermore, when the reciprocating screw rod 505 rotates, the reciprocating screw rod 505 drives the connecting shaft 511 and the fan blade 513 to rotate at the same time, so that the fan blade 513 drives the air flow to enter the blowing cylinder 512 from the direction close to the connecting shaft 511, and then flows from the blowing cylinder 512 to the connecting pipe 514, and then enters the blowing pipe 515, and finally sprays out from the blowing head of the blowing pipe 515 from bottom to top, thereby promoting the air flow on the outer surface of the air intake pipe 3, thereby improving the heat exchange rate of the air intake pipe 3, and through the U-shaped setting of the air intake pipe 515, the air injection head is also distributed in a U-shape on the outer surface of the air intake pipe 515, so that when the air blowing head blows, it fits the outer surface of the air intake pipe 3 more closely, thereby making the air flow contact with the outer surface of the air intake pipe 3 in a larger range, thereby improving the cooling effect on the air intake pipe 3, preventing the air intake pipe 3 from overheating and accelerating the aging of the air intake pipe 3, and improving the durability of the air intake pipe 3;

[0062] Please refer to the above working process Figures 9 to 12 .

[0063] The following is the working process of the pre-treatment replacement mechanism 4 for pre-treating the smoke entering the filter body 1:

[0064] When external smoke enters the filter body 1 from the air inlet pipe 3 for filtering, the external smoke first passes through the fixing box 401 and the bellows. When the smoke passes through the fixing box 401, some impurities in the smoke will be blocked by the fixing box 401, so that the smoke entering the filter body 1 is cleaner, thereby reducing the saturation speed of the filter element in the filter body 1, thereby reducing the frequency of disassembly and maintenance of the filter element in the filter body 1. At the same time, when the filter screen 402 has been used for a long time and is saturated, the staff can hold the push-pull frame 404 and then pull the T-shaped slide post 416 with their fingers to slide the T-shaped slide post 416 away from the installation box 419, thereby driving the push post 41 8 slides in the direction away from the installation box 419, so that one end of the push column 418 is separated from the obstruction of the clamping column 421. Due to the inclined setting of the clamping column 421, it will be affected by gravity at this time, and the clamping column 421 will slide in the direction away from the limit block 420, so that one end of the clamping column 421 is separated from the plugging with the limit block 420. At this time, the T-shaped sliding column 416 is continued to be pulled, so that the force of the T-shaped sliding column 416 acts on the push-pull frame 404, so that the push-pull frame 404 drives the sealing connection frame 403 and the filter screen 402 to slide toward the side of the fixed box 401. The fixing and removal of the filter screen 402 can be completed by simply pulling, which is simple and convenient to operate and saves the time of removing the filter screen 402.

[0065] During the sliding of the filter screen 402, the push-pull frame 404 simultaneously drives the rack 405 to slide, and then, with the cooperation of the rack 405 and the gear 408, the gear 408 rotates and drives the cleaning roller 407 and the turntable 409 to rotate, and then the surface of the sliding filter screen 402 can be cleaned by the rotation of the cleaning roller 407 and the bristles 4071, and at the same time, the umbrella-shaped setting of the bristles 4071 makes the bristle 4071 umbrella-shaped structure, when in contact with the filter holes on the filter screen 402, be affected by the filter holes so that the bristle 4071 umbrella-shaped structure is deformed and inserted into the filter holes, and the round edge of the umbrella-shaped structure abuts against the inner surface of the filter hole, and then when pulled out, the filter hole can be cleaned by the round edge of the bristle 4071 umbrella-shaped structure, thereby improving the cleaning effect of the cleaning roller 407 on the filter screen 402;

[0066] Furthermore, in the process of the cleaning roller 407 driving the turntable 409 to rotate, the turntable 409 also drives the protrusion 410 to rotate, and the protrusion 410 rotates and approaches the slide bar 412, so that the arc surface of the protrusion 410 squeezes the arc surface of the slide bar 412, causing the slide bar 412 to slide away from the protrusion 410, and at the same time the tensioning spring 413 is tensioned, and then when the protrusion 410 is offset from the slide bar 412, the slide bar 412 is reset due to the rebound of the spring, and then in the process of the turntable 409 driving the protrusion 410 to rotate, the tensioning spring 413 and the protrusion 410 cooperate to make the connecting rod 414 drive the knocking head 415 to continuously knock with the surface of the filter screen 402, so that the knocking area of ​​the filter screen 402 generates a certain vibration through the knocking, so that part of the impurities on the surface of the filter screen 402 can be shaken off by the vibration, thereby further improving the cleaning effect of the filter screen 402 when the filter screen 402 is taken out.
