Description

Technical Field

[0001] This utility model relates to the field of engineering waste gas collection and treatment technology, and specifically discloses an engineering waste gas collection and treatment device. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification. Currently, waste gas in engineering projects is mostly treated through waste gas treatment and collection devices.

[0003] Existing engineering waste gas collection and treatment devices typically require the use of filters to reduce or filter fine particles such as dust in the waste gas. However, during use, a large number of fine dust particles adhere to the surface of the filters in existing waste gas collection and treatment devices, making it inconvenient to clean the fine dust particles in a timely manner. This can easily reduce the working efficiency of the waste gas collection and treatment device. At the same time, existing engineering waste gas collection and treatment devices are inconvenient to disassemble, maintain, or replace the filters. The disassembly and installation process of the filters is relatively cumbersome and time-consuming, making them inconvenient to use. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-8 An engineering waste gas collection and treatment device includes a treatment box 1, and a cleaning mechanism is provided inside the treatment box 1.

[0030] The upper surface of the processing box 1 has multiple left and right distributed storage slots 2. The lower end of each of the multiple storage slots 2 has a notch 3. The interior of the processing box 1 is fixedly connected to multiple mounting brackets 4 with open upper ends that match the multiple notches 3. The inner wall of the mounting brackets 4 has a limiting groove 5. The interior of each of the multiple storage slots 2 is provided with a mounting plate 6. The lower end of each of the multiple mounting plates 6 is fixedly connected to a filter screen 7 that passes through the multiple notches 3 and extends into the multiple limiting grooves 5. A fixing mechanism is provided between the mounting plate 6 and the storage slot 2.

[0031] The cleaning mechanism includes multiple multi-stage electric telescopic rods 8 installed on the upper surface of the treatment box 1. The multiple multi-stage electric telescopic rods 8 are staggered with multiple storage slots 2. The output ends of the multiple multi-stage electric telescopic rods 8 extend into the interior of the treatment box 1 and are fixedly connected to the mounting block 9. The lower end of the mounting block 9 is rotatably connected to the turntable 10. The lower end of the turntable 10 is fixedly connected to the drive pin 11 located on one side of the central axis. The right side of the lower end of the mounting block 9 is fixedly connected to the limiting plate 12. A first through hole 13 is opened through one side wall of the limiting plate 12. A slide rod 14 is slidably connected inside the first through hole 13. The left end of the slide rod 14 extends to the left side of the first through hole 13 and is fixedly connected to the drive ring 15. The drive pin 11 is located inside the drive ring 15. The right end of the slide rod 14 extends to the right side of the first through hole 13 and is fixedly connected to the mounting bar 16. The right side wall of the mounting bar 16 is fixedly connected to multiple front-to-back distributed tapping balls 17 that match the filter screen 7.

[0032] In this embodiment: During use, the exhaust gas conveying pipe and the exhaust pipe are connected to the inlet pipe 30 and the exhaust pipe 31, respectively. Then, the exhaust gas is conveyed into the treatment box 1 through the exhaust gas conveying pipe and the inlet pipe 30, so that the exhaust gas passes through multiple filter screens 7 in sequence. The dust particles in the exhaust gas are filtered through the multiple filter screens 7. Then, the filtered exhaust gas is discharged from the treatment box 1 through the exhaust gas exhaust pipe and the exhaust pipe 31, thereby filtering the exhaust gas. Since the mesh size of the multiple filter screens 7 increases from left to right, the dust particles in the exhaust gas can be filtered multiple times through the multiple filter screens 7, which effectively improves the treatment effect of the exhaust gas.

[0033] During the processing, the adsorbed dust particles can be cleaned by the cleaning mechanism. Specifically, the multi-stage electric telescopic rod 8 is activated, which drives the mounting block 9 to move up and down reciprocally. While the mounting block 9 moves, the turntable 10 rotates, and the turntable 10 drives the drive pin 11 to rotate around the central axis of the turntable 10. Then, the drive pin 11, in conjunction with the drive ring 15, drives the slide rod 14 to move left and right reciprocally. The limit plate 12 and the first through hole 13 can limit the slide rod 14, so that the slide rod 14 moves left and right smoothly. Then, the slide rod 14, in conjunction with the mounting bar 16, drives multiple striking balls 17 to move left and right reciprocally. The multiple striking balls 17 moving left and right and up and down reciprocally strike the filter screen 7, thereby cleaning the dust particles adsorbed on the surface of the filter screen 7 in a timely manner, avoiding the dust particles from affecting the working efficiency of the exhaust gas treatment and collection device. Then, the dust particles knocked down fall into the collection box 24 through multiple dust passage holes 23, and the dust particles are collected and processed centrally through the collection box 24.

[0034] When disassembling, maintaining, or replacing the filter screen 7, release the fixing mechanism from the mounting plate 6, and then pull the filter screen 7 through the mounting plate 6 to pull the filter screen 7 out of the limiting groove 5 through the notch 3, thereby quickly disassembling the filter screen 7. The installation can be done by reversing the operation, thus quickly disassembling and installing the filter screen 7, effectively improving the efficiency of disassembling and installing the filter screen 7 and making it convenient to use.

[0035] As a technical optimization of this utility model, the fixing mechanism includes fixing grooves 18 opened on the inner sidewalls of the front and rear sides of the storage groove 2;

[0036] The mounting plate 6 has a cavity 19 inside. The front and rear ends of the mounting plate 6 are both provided with second through holes 20 that communicate with the cavity 19. Two racks 21 are slidably connected inside the cavity 19. The opposite ends of the two racks 21 pass through the two second through holes 20 and extend into the interior of the two fixing grooves 18 respectively.

[0037] In this embodiment: the two racks 21 move in opposite directions, so that the two racks 21 are removed from the two fixing slots 18 respectively and put into the two second through holes 20 respectively, thereby releasing the locking and fixing state between the racks 21 and the fixing slots 18, thereby releasing the fixing state between the mounting plate 6 and the storage slot 2.

[0038] As a technical optimization of this utility model, a collection box 22 with an open front end is fixedly connected to the lower end of the processing box 1. A dust passage hole 23 is provided through the lower end of the interior of the processing box 1, which is staggered with multiple mounting brackets 4 and communicates with the collection box 22. A storage box 24 with an open upper end is slidably connected inside the collection box 22. The front end of the storage box 24 extends to the front end of the collection box 22 and is fixedly connected to a sealing plate 25. The rear end face of the sealing plate 25 abuts against the front end face of the collection box 22.

[0039] In this embodiment, the dust particles knocked down fall into the collection box 24 through multiple dust passage holes 23. The collection box 24 collects and processes the dust particles. The sealing plate 25 can seal the front opening of the collection box 22 to prevent dust particles from being discharged from the front opening of the collection box 22.

[0040] As a technical optimization of this utility model, a drive motor 26 is installed inside the mounting block 9, and the output end of the drive motor 26 is fixedly connected to the rotation shaft of the turntable 10.

[0041] In this embodiment, the drive motor 26 can drive the turntable 10 to rotate.

[0042] As a technical optimization of this utility model, the cavity 19 is rotatably connected to a gear 27 that meshes with two racks 21. The rotation shaft of the gear 27 extends to the top of the mounting plate 6 and is fixedly connected to a torsion block.

[0043] In this embodiment: the torsion block drives the gear 27 to rotate, and the gear 27 drives the two racks 21 to move in opposite directions.

[0044] As a technical optimization of this utility model, a first magnet 28 is fixedly connected inside the fixing groove 18, and a second magnet 29 matching the first magnet 28 is fixedly connected to one end of the rack 21.

[0045] In this embodiment, the rack 21 can be attracted into the fixing groove 18 by the cooperation between the first magnet 28 and the second magnet 29, preventing the rack 21 from falling out of the fixing groove 18.

[0046] As a technical optimization of this utility model, the left and right side walls of the processing box 1 are respectively connected to an air inlet pipe 30 and an exhaust pipe 31.

[0047] In this embodiment: the air inlet pipe 30 facilitates the delivery of waste gas into the treatment box 1, and the exhaust pipe 31 facilitates the discharge of the filtered waste gas from the treatment box 1.

[0048] The working principle and usage process of this utility model are as follows: When in use, the exhaust gas conveying pipe and the exhaust pipe are connected to the inlet pipe 30 and the exhaust pipe 31 respectively. Then, the exhaust gas is conveyed into the treatment box 1 through the exhaust gas conveying pipe and the inlet pipe 30, so that the exhaust gas passes through multiple filter screens 7 in sequence. The dust particles of the exhaust gas are filtered through the multiple filter screens 7. Then, the filtered exhaust gas is discharged from the treatment box 1 through the exhaust gas discharge pipe and the exhaust pipe 31, thereby filtering the exhaust gas.

[0049] During the processing, the adsorbed dust particles can be cleaned by a cleaning mechanism. Specifically, the multi-stage electric telescopic rod 8 is activated, which drives the mounting block 9 to move up and down reciprocally. Simultaneously, the drive motor 26 is activated, which drives the turntable 10 to rotate. The turntable 10 then drives the drive pin 11 to rotate around its central axis. The drive pin 11, in conjunction with the drive ring 15, drives the slide rod 14 to move left and right reciprocally. The slide rod 14 is limited by the limiting plate 12 and the first through hole 13. Positioning allows the slide bar 14 to move smoothly back and forth left and right. Then, the slide bar 14, in conjunction with the mounting bar 16, drives multiple striking balls 17 to move back and forth left and right. The multiple striking balls 17, moving back and forth left and right and up and down, strike the filter screen 7, thereby cleaning the dust particles adsorbed on the surface of the filter screen 7 in a timely manner. This prevents the dust particles from affecting the working efficiency of the exhaust gas treatment and collection device. Then, the dust particles knocked down fall into the collection box 24 through multiple dust passage holes 23, and the dust particles are collected and processed centrally through the collection box 24.

[0050] When disassembling, maintaining, or replacing the filter screen 7, the torsion block drives the gear 27 to rotate. The gear 27 drives the two racks 21 to move in opposite directions, causing the two racks 21 to move out of the two fixing slots 18 and into the two second through holes 20 respectively. This releases the locking state between the racks 21 and the fixing slots 18, thereby releasing the fixing state between the mounting plate 6 and the storage slot 2. Then, the mounting plate 6 pulls the filter screen 7, pulling it out of the limiting slot 5 through the notch 3, thus quickly disassembling the filter screen 7. Installation is done by reversing the operation, which quickly disassembles and installs the filter screen 7, effectively improving the efficiency of disassembly and installation and making it convenient to use.
