Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, and specifically relates to a wet triple-effect dust removal device. Background Technology
[0002] Wet scrubbers use water to wash dust-laden air to achieve dust removal. A wet triple-effect dust collector is an organic combination of two-stage cyclone dust collection and one-stage water dust collection. Due to its advantages such as simple structure, economic practicality, easy operation, low maintenance workload, small footprint, and low water quality requirements, it is widely used for dust collection of non-hydrophobic dust-laden gases in industries such as mining, metallurgy, cement, chemical, and papermaking.
[0003] Referring to patent publication number CN222489349U, a flow guiding mechanism for a wet scrubber is disclosed, relating to the field of wet scrubbers. The device includes a wet scrubber body, a baffle channel fixedly installed on one side of the body, two sets of baffle mechanisms fixedly installed inside the baffle channel, an air inlet channel fixedly installed on one side of the baffle channel, a support frame fixedly installed on one side of the top surface of the air inlet channel, an opening and closing mechanism fixedly installed on the top surface of the support frame, a filter screen movably installed on the other side of the top surface of the air inlet channel, and a dust collection box fixedly installed on the bottom surface of the air inlet channel. This invention, through the setting of the opening and closing mechanism, connects the connecting screw to the external air inlet pipe, and the sealing ring seals the connection to prevent air leakage. Opening the cylinder drives the opening and closing gate to rise and fall, changing the number of four sets of air passages opening and closing, thereby achieving the effect of adjusting the air intake rate of dust-laden gas.
[0004] In the aforementioned patent, the incoming dust-laden gas is initially filtered through a filter screen, and solid impurities fall into the dust collection box for collection. However, during the operation of a wet scrubber, dust-laden gas is drawn into the device for filtration by suction. Because the gas carries a large amount of dust, the number of impurities intercepted by the filter screen is enormous. As the wet scrubber continues to operate, the filter screen continuously filters impurities, and a large number of impurities adhere to its surface. The suction generated by the wet scrubber during operation not only fails to cause the impurities on the filter screen to fall directly into the dust collection box, but also causes the impurities to adhere more tightly to the filter screen due to the suction. Only when the filter screen is completely blocked, preventing airflow, or when the wet scrubber stops working and loses suction, will the impurities fall into the dust collection box under the action of gravity. Moreover, as the wet scrubber operates for a long time, impurities continue to accumulate and adhere, gradually clogging the filter screen, leading to a decrease in the gas flow efficiency of the equipment, and thus affecting the overall dust removal effect.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in the related technologies, this utility model proposes a wet triple-effect dust removal device to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to a wet triple-effect dust collector, comprising a wet triple-effect dust collector body, one end of which is connected to an air inlet pipe, an air inlet channel is installed on the air inlet pipe, a filter screen is installed on the inner wall of the air inlet channel, an impurity cleaning mechanism is installed on one side of the filter screen, first triangular blocks are symmetrically installed on both sides of the bottom of the impurity cleaning mechanism, a dust collection box is connected to the bottom of the air inlet channel, an elastic baffle assembly is installed above the inner cavity of the dust collection box, a bracket is fixedly installed on the outer wall of the dust collection box, one end of the elastic baffle assembly is installed on the bracket, an external connector is connected to the end of the air inlet channel away from the air inlet pipe, and a second triangular block is fixedly installed on the top of the elastic baffle assembly, with the inclined surfaces of the two first triangular blocks and the inclined surfaces of the second triangular blocks engaging in a pressing fit.
[0009] Furthermore, the impurity cleaning mechanism includes a hydraulic rod, which is fixedly installed at the top of the air inlet channel, and a connecting plate is fixedly installed at the telescopic end of the hydraulic rod within the air inlet channel cavity.
[0010] Furthermore, a first intercepting frame is fixedly installed on the connecting plate near the filter screen end, and a second intercepting frame is fixedly installed on the connecting plate away from the first intercepting frame end.
[0011] Furthermore, both the first and second interception frames are equipped with interception nets, and a scraper is fixedly installed at the bottom of the first interception frame, with the scraper closely attached to one end of the filter net.
[0012] Furthermore, the elastic baffle assembly includes a baffle plate that is slidably mounted on the dust collection box, and the second triangular block is fixedly mounted on the top of the baffle plate.
[0013] Furthermore, the isolation plate is fixedly installed with multiple sliding rods protruding from the dust collection box end, and the multiple sliding rods are slidably installed on the bracket.
[0014] Furthermore, elastic elements are fitted onto the plurality of sliding rods, with one end of the elastic element fixedly mounted on the isolation plate and the other end fixedly mounted on the bracket.
[0015] Furthermore, the external connector includes a threaded pipe with an annular groove, and an annular airbag is provided in the annular groove.
[0016] This utility model has the following beneficial effects:
[0017] This invention activates the impurity cleaning mechanism, which moves along the filter screen towards the elastic baffle assembly. During its movement, the impurity cleaning mechanism scrapes off solid impurities from the filter screen. As it moves, fixed impurities enter the impurity cleaning mechanism. Inside, a suction force acts on the solid impurities to prevent them from falling off the filter screen and being drawn back onto it. Thus, the impurity cleaning mechanism cleans the filter screen during the operation of the wet triple-effect dust collector, avoiding clogging caused by a large amount of impurities adhering to the filter screen. This ensures the filter screen always maintains good filtration performance and improves gas flow efficiency.
[0018] This invention, through the effective cooperation of the impurity cleaning mechanism and the elastic baffle assembly, ensures that solid impurities can smoothly enter the dust collection box, and the sealed design of the dust collection box prevents the impurities from being re-entrained and flowing back, thus ensuring the reliability of impurity collection.
[0019] This utility model relates to an external connector that connects to an external air intake pipe. By screwing the external air intake pipe onto the external connector, as the external air intake pipe is continuously screwed, the external connector extends into the inner cavity of the external air intake pipe. At the same time, the external air intake pipe squeezes the corresponding components of the external connector, causing the corresponding components of the external connector to be squeezed and deformed, and filling the gap between the external connector and the external air intake pipe. This improves the sealing between the two, reduces the possibility of dust-laden gas leakage, and ensures the efficient operation of the entire dust removal system.
[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0032] Please see Figures 1-6As shown, this utility model is a wet triple-effect dust collector, including a wet triple-effect dust collector body 1. One end of the wet triple-effect dust collector body 1 is connected to an air inlet pipe 2. An air inlet channel 3 is installed on the air inlet pipe 2. A filter screen 4 is installed on the inner wall of the air inlet channel 3. An impurity cleaning mechanism 5 is installed on one side of the filter screen 4. First triangular blocks 6 are symmetrically installed on both sides of the bottom of the impurity cleaning mechanism 5. A dust collection box 7 is connected to the bottom of the air inlet channel 3. An elastic baffle assembly 8 is installed on the upper part of the inner cavity of the dust collection box 7. A bracket 9 is fixedly installed on the outer wall of the dust collection box 7. One end of the elastic baffle assembly 8 is installed on the bracket 9. An external connector 10 is connected to the end of the air inlet channel 3 away from the air inlet pipe 2. A second triangular block 11 is fixedly installed on the top of the elastic baffle assembly 8. The inclined surfaces of the two first triangular blocks 6 and the inclined surfaces of the second triangular blocks 11 are pressed together.
[0033] The external connector 10 is connected to the external air inlet pipe. By screwing the external air inlet pipe onto the external connector 10, as the external air inlet pipe is continuously screwed, the external connector 10 continuously extends into the inner cavity of the external air inlet pipe. At the same time, the external air inlet pipe squeezes the corresponding parts of the external connector 10, causing the corresponding parts of the external connector 10 to be squeezed and deformed, filling the gap between the external connector 10 and the external air inlet pipe, thus improving the sealing between the two and reducing the possibility of dust-laden gas leakage. This ensures the efficient operation of the entire dust removal system. When the wet triple-effect dust collector body 1 starts, it generates suction force, causing the dust-laden gas to pass sequentially through the external air inlet pipe, external connector 10, air inlet channel 3, filter screen 4, and air inlet pipe 2, and finally enter the wet triple-effect dust collector body 1 for washing treatment. The dust-laden gas undergoes preliminary filtration when passing through the filter screen 4, and solid impurities in the gas are intercepted by the filter screen 4. Under the action of the suction force of the wet triple-effect dust collector body 1... Regarding the adhesion of solid impurities, solid impurities will adhere to the surface of the filter screen 4. When it is necessary to clean the solid impurities on the filter screen 4, the impurity cleaning mechanism 5 is activated. The impurity cleaning mechanism 5 will move along the filter screen 4 towards the elastic baffle assembly 8. During the movement, the impurity cleaning mechanism 5 can scrape off the solid impurities on the filter screen 4. As the impurity cleaning mechanism 5 moves, the fixed impurities will enter the impurity cleaning mechanism 5. Inside the impurity cleaning mechanism 5, the suction force also acts on the solid impurities to prevent the solid impurities scraped off by the impurity cleaning mechanism 5 from falling directly off the filter screen 4 and being sucked back onto the filter screen 4 by the suction force. Thus, the impurity cleaning mechanism 5 can clean the filter screen 4 during the operation of the wet triple-effect dust collector body 1, avoiding the clogging problem caused by a large number of impurities adhering to the filter screen 4, ensuring that the filter screen 4 always has good filtration performance, and improving the gas flow efficiency.
[0034] As the impurity cleaning mechanism 5 moves the solid impurities, when it reaches below the filter screen 4, the two first triangular blocks 6 on the mechanism contact the second triangular block 11. Due to the pressing fit between the inclined surfaces of the two first triangular blocks 6 and the inclined surfaces of the second triangular block 11, the two first triangular blocks 6 push the second triangular block 11 to move as the mechanism moves. The second triangular block 11 then moves the elastic baffle assembly 8 on it, increasing the elastic potential energy inside the elastic baffle assembly 8. This movement exposes the inner cavity of the dust collection box 7 to the view of the impurity cleaning mechanism 5. When the impurity cleaning mechanism 5 reaches the bottom of the filter screen 4, it has removed the impurities from the filter screen 4. After one cleaning cycle, the filter screen 4 regains its function of intercepting solid impurities in the dusty gas. At this time, the cleaning part of the impurity cleaning mechanism 5 also fully enters the inner cavity of the dust collection box 7. The fixed impurities in the impurity cleaning mechanism 5 will no longer be subject to suction and will fall into the inner cavity of the dust collection box 7 to complete the collection of solid impurities. The dust collection box 7 can be hinged with a box door, but the box door and the dust collection box 7 are sealed with a sealing ring to prevent the solid impurities that have entered the inner cavity of the dust collection box 7 from returning to the filter screen 4 due to suction. In addition, through the effective cooperation of the impurity cleaning mechanism 5 and the elastic baffle assembly 8, it is ensured that solid impurities can smoothly enter the dust collection box 7. The sealing design of the dust collection box 7 prevents the impurities from being re-entrained and flowing back, ensuring the reliability of impurity collection.
[0035] In one embodiment, the impurity cleaning mechanism 5 includes a hydraulic rod 501, which is fixedly installed on the top of the air inlet channel 3. A connecting plate 502 is fixedly installed at the telescopic end of the hydraulic rod 501 and inside the air inlet channel 3.
[0036] A first intercepting frame 503 is fixedly installed on the end of the connecting plate 502 near the filter screen 4, and a second intercepting frame 504 is fixedly installed on the end of the connecting plate 502 away from the first intercepting frame 503.
[0037] Both the first interception frame 503 and the second interception frame 504 are equipped with interception nets 505. A scraper 506 is fixedly installed at the bottom of the first interception frame 503, and the scraper 506 is in close contact with one end of the filter screen 4.
[0038] The elastic baffle assembly 8 includes a baffle plate 801, which is slidably mounted on the dust collection box 7, and the second triangular block 11 is fixedly mounted on the top of the baffle plate 801.
[0039] The isolation plate 801 protrudes from the dust collection box 7 and is fixedly installed with multiple sliding rods 802, all of which are slidably mounted on the bracket 9.
[0040] An elastic element 803 is sleeved on one or more of the sliding rods 802. One end of the elastic element 803 is fixedly installed on the isolation plate 801 and the other end is fixedly installed on the bracket 9.
[0041] When it is necessary to clean solid impurities on the filter screen 4, the hydraulic rod 501 is activated. Since the hydraulic rod 501 is fixedly installed at the top of the air inlet channel 3, and its telescopic end is fixedly connected to the connecting plate 502, the telescopic movement of the hydraulic rod 501 will drive the connecting plate 502 to move. A first intercepting frame 503 is fixedly installed at one end of the connecting plate 502 near the filter screen 4, and a second intercepting frame 504 is fixedly installed at the other end. Both the first intercepting frame 503 and the second intercepting frame 504 are equipped with intercepting nets 505. As the connecting plate 502 moves, the first intercepting frame 503 and the second intercepting frame 504 will also move. The scraper 506 fixedly installed at the bottom of the first intercepting frame 503 is in close contact with the filter screen 4. When the connecting plate 502 drives the first intercepting frame 503 to move, the scraper 506 will move. When frame 503 moves, scraper 506 slides along the surface of filter screen 4, scraping off solid impurities attached to filter screen 4. The scraped impurities are intercepted by interception nets 505 on the first interception frame 503 and the second interception frame 504, preventing the impurities from scattering after being scraped off. At the same time, the suction force generated by the wet triple-effect dust collector body 1 acts on the solid impurities through the interception nets 505, preventing the impurities from falling back to filter screen 4. It should be noted that the mesh size of the interception net 505 is much smaller than that of the filter screen 4. When the connecting plate 502, the first interception frame 503, the second interception frame 504, and the two interception nets 505 move the solid impurities continuously to below filter screen 4, the two first triangular blocks 6 contact the second triangular block 11. The two first triangular blocks 6 are inclined and pressed together with the second triangular block 11. As the two first triangular blocks 6 move continuously, they push the second triangular block 11 to move. The second triangular block 11 is fixedly installed on the top of the isolation plate 801, which is slidably installed on the dust collection box 7. Therefore, the movement of the second triangular block 11 will drive the isolation plate 801 to move. Multiple sliding rods 802 are fixedly installed on the end of the isolation plate 801 that protrudes from the dust collection box 7. These sliding rods 802 are all slidably installed on the bracket 9. When the isolation plate 801 moves, the sliding rods 802 slide on the bracket 9. At the same time, the elastic element 803 (preferably a spring) sleeved on the sliding rod 802 is compressed. As the potential energy increases, the inner cavity of the dust collection box 7 is gradually exposed to the view of the connecting plate 502, the first intercepting frame 503, the second intercepting frame 504, the two intercepting nets 505, and the scraper 506 as the isolation plate 801 moves. When the connecting plate 502 moves to the bottom of the filter screen 4, the scraper 506 has already cleaned the solid impurities on the filter screen 4. Since the impurities are no longer subject to suction after entering the inner cavity of the dust collection box 7, they will fall into the dust collection box 7 due to gravity and be collected. Afterwards, when the hydraulic rod 501 moves in the opposite direction, the elastic element 803 releases elastic potential energy, pushing the isolation plate 801 to move in the opposite direction and return to the initial position, thus covering the dust collection box 7 again and preventing the collected impurities from returning to the filter screen 4 due to suction.
[0042] In one embodiment, the external connector 10 includes a threaded pipe 1001, an annular groove 1002 is provided on the threaded pipe 1001, and an annular airbag 1003 is provided in the annular groove 1002.
[0043] The external air intake pipe is screwed onto the threaded pipe 1001. As the external air intake pipe is continuously screwed, the threaded pipe 1001 continuously enters the inner cavity of the external air intake pipe. Subsequently, the external air intake pipe comes into contact with the annular airbag 1003 in the annular groove 1002. As the external air intake pipe is screwed in, it compresses the annular airbag 1003, causing the gas compressed by the external air intake pipe to fill the gap between the external air intake pipe and the annular groove 1002, thus improving the sealing between the air intake pipe and the threaded pipe 1001.
