Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for bromothalonil pesticide production. BACKGROUND

[0002] Bromothalonil is a highly effective and broad-spectrum fungicide widely used in agricultural production. Its production process produces waste gas containing various pollutants. The activated carbon adsorption tower, due to its adaptation to the characteristics of waste gas and stable purification effect, has become the mainstream waste gas treatment device for bromothalonil pesticide production. The porous structure (specific surface area ≥1000 m 2 / g) of activated carbon can efficiently physically adsorb low-concentration VOCs, and the adsorption efficiency of various organic pollutants in bromothalonil production waste gas can reach more than 90%. Moreover, the adsorption process is only physical interception, and no new toxic and harmful gases are produced. Saturated activated carbon can be treated by qualified units for harmless treatment as hazardous waste, meeting environmental protection compliance requirements.

[0003] The activated carbon adsorption tower needs to be replaced with saturated high-efficiency activated carbon after long-term operation. Non-stop replacement has become the core improvement direction of such equipment. For example, compared with the tail gas purification device and process based on activated carbon method disclosed in Chinese Patent No. CN115634548B and the organic waste gas separation and treatment device disclosed in Chinese Patent No. CN118594193B.

[0004] Although the above-mentioned scheme realizes non-stop replacement and effectively improves waste gas treatment efficiency and quality, it still has the common defect that it is not convenient to pack waste materials when replacing high-efficiency activated carbon, like most existing waste gas treatment devices for bromothalonil pesticide production. Because the activated carbon waste material after adsorbing waste gas contains a large amount of pollutants, the existing replacement method requires operators to contact and handle waste materials at close range, which not only easily causes secondary pollution, but also makes harmful substances and dust in waste materials easily adhere to the human body and even enter the body through respiration, posing a serious threat to the health of operators.

DETAILED DESCRIPTION

[0035] The technical solutions of the present application will be further illustrated below with reference to the accompanying drawings and specific embodiments.

[0036] The accompanying drawings are only used for illustrative purposes, and the representations are only schematic diagrams, not physical diagrams, and should not be understood as limiting the present patent; in order to better illustrate the embodiments of the present application, some components in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0038] In the description of the present application, unless otherwise explicitly specified and limited, if the term "connection" and the like appear to indicate the connection relationship between components, the term should be interpreted broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] As shown in the drawings: Figures 1 to 14 A bromoxynil pesticide production waste gas treatment device, comprising a tower body 1 and a plurality of activated carbon plates 13, a pair of adsorption cavities 10 is opened at the top of the tower body 1, the activated carbon plate 13 is inserted and matched with the adsorption cavity 10, further comprising a replacement assembly 2, a lower hopper 14, a packaging bag 15, a continuous feeding assembly 3, a pair of heat sealing knives 16 and a driving assembly 4, the replacement assembly 2 is installed on the tower body 1, the replacement assembly 2 is used for replacing the activated carbon plate 13 without stopping, the lower hopper 14 is located below the adsorption cavity 10 and is fixedly connected with the inner wall of the tower body 1, the packaging bag 15 is detachably installed below the adsorption tower through the continuous feeding assembly 3, the packaging bag 15 can catch the falling activated carbon plate 13, the two heat sealing knives are horizontally movably installed on both sides of the packaging bag 15 through the driving assembly 4, and the heat sealing knives are used for heat sealing the packaging bag 15.

[0040] ​When replacing the activated carbon plate 13, one of the electrically controlled valves 25 on the three-way pipe 20 is closed to prevent waste gas from entering the corresponding adsorption chamber 10. The bottom plate 220 at the bottom of one of the adsorption chambers 10 is opened by the replacement component 2, causing the activated carbon plate 13 inside to fall downwards and slide into the packaging bag 15 through the hopper 14. Then, the two heat sealing blades 16 are driven by the drive component 4 to approach each other and clamp the top of the packaging bag 15. The opening of the packaging bag 15 is heat-sealed by the heat sealing blades. Then, the cutter 38 cuts the connecting part 151 of the packaging bag 15, allowing the packaging bag 15 containing waste to be discharged downwards through the waste outlet. This allows the waste to be packaged after replacing the activated carbon, avoiding secondary pollution.

[0041] After the waste is discharged, the bottom plate 220 is rotated to reset, and the cover plate on the top of the corresponding adsorption chamber 10 is opened. Then, a new activated carbon plate 13 is inserted into it, which can achieve the replacement of activated carbon without stopping the machine.

[0042] Finally, the continuous feeding component 3 moves the clamping mechanism 5 to the packaging bag 15, clamps the connecting part 151 of the packaging bag 15, and then the clamping mechanism 5 resets to open the packaging bag 15, preparing for the next packaging of waste materials, thereby realizing continuous packaging.

[0043] like Figures 1 to 11 As shown: The drive assembly 4 includes a pair of lower racks 40, a pair of upper racks 41, a pair of spur gears 42, and a first motor 43. The first motor 43 is fixedly connected to the inner wall of the tower body 1. The output shaft of the first motor 43 is coaxially connected to one of the spur gears 42. The two spur gears 42 are rotatably connected to the inner walls at both ends of the tower body 1. The lower racks 40 and the upper racks 41 are slidably connected to the inner wall of the tower body 1. The two lower racks 40 are fixedly connected to one of the heat sealing knives 16, and the two upper racks 41 are fixedly connected to the other heat sealing knives 16. The lower racks 40 mesh with the bottom of the spur gears 42, and the upper racks 41 mesh with the top of the spur gears 42.

[0044] The drive assembly 4 also includes a pair of opening mechanisms 44, which are located at both ends of the packaging bag 15. Each opening mechanism 44 includes a screw 440, a guide rod 441, a slider 442, and a plumb rod 443. One end of the screw 440 is rotatably connected to the hopper 14, and the other end of the screw 440 passes through the inner wall of the tower body 1 and is coaxially connected to the spur gear 42. The screw 440 passes through the slider 442 and is threadedly connected to it. One end of the guide rod 441 is fixedly connected to the hopper 14, and the other end of the guide rod 441 is fixedly connected to the inner wall of the tower body 1. The guide rod 441 passes through the slider 442 and is slidably connected to it. The top of the plumb rod 443 is hinged to the slider 442, and the bottom of the plumb rod 443 abuts against the inner wall of the packaging bag 15.

[0045] The first motor 43 is activated, and its output shaft drives one of the spur gears 42 to rotate. Through the meshing transmission between the spur gear 42 and the upper rack 41 and the lower rack 40, the two heat sealing knives 16 can be driven to move horizontally at the same time. Since the sliding directions of the upper rack 41 and the lower rack 40 are opposite, the two heat sealing knives 16 move closer or further away synchronously, thereby realizing the heat sealing and sliding reset of the packaging bag 15.

[0046] Simultaneously, the movement of the upper rack 41 and lower rack 40 synchronously drives another spur gear 42 to rotate, causing the two screws 440 to rotate synchronously. Through the threaded transmission between the screws 440 and the slider 442, the slider 442 can drive the vertical rod 443 to move horizontally to both sides along the guide rod 441. This causes the vertical rod 443 to press against the inner wall of the packaging bag 15 and expand to both sides, making the packaging bag 15 flatter and improving the sealing quality of the heat sealing knife 16, ensuring that waste does not leak. Furthermore, the vertical rod 443 is hinged to the slider 442. When the support rod 36 moves horizontally and contacts it, the vertical rod 443 can rotate to avoid obstructing the movement of the support rod 36.

[0047] like Figures 1 to 12 As shown: The continuous feeding assembly 3 includes a support roller 30, a universal joint 31, and a second motor 32. The second motor 32 is fixedly connected to the inner wall of the tower body 1. The output shaft of the second motor 32 is coaxially connected to one end of the universal joint 31, and the other end of the universal joint 31 is coaxially connected to one end of the support roller 30. A feeding port 11 is provided on one side of the tower body 1. A groove 12 is provided on the inner wall of one end of the feeding port 11. The other end of the support roller 30 is rotatably connected to the groove 12. The support roller 30 is located on one side of the bottom of the discharge hopper 14. There are multiple packaging bags 15. Each packaging bag 15 includes a bag body 150 and a pair of connecting parts 151. The bottom of the two connecting parts 151 is fixedly connected to the top two sides of the bag body 150, and one of the connecting parts 151 is fixedly connected to the bottom of the bag body 150. Multiple packaging bags 15 can be arranged around the support roller 30.

[0048] The continuous feeding assembly 3 also includes a clamping plate 33, a pair of slide rails 34, a pair of electric slide tables 35, a support rod 36, and a pair of clamping mechanisms 5. The two slide rails 34 are fixedly connected to the inner walls of both ends of the tower body 1, the electric slide tables 35 are slidably connected to the outer periphery of the slide rails 34, the two ends of the support rod 36 are fixedly connected to the two electric slide tables 35, the two clamping mechanisms 5 are respectively installed at both ends of the support rod 36, and the clamping mechanisms 5 are used to clamp another connecting part 151. The clamping plate 33 is installed between the two clamping mechanisms 5, and the support rod 36 and the vertical rod 443 abut against each other.

[0049] The clamping mechanism 5 comprises a turnover table 50, a hydraulic rod 51, an arc-shaped pressing rod 52 and a rotating rod 53. The turnover table 50 is hingedly connected to one side of the supporting rod 36, and the two ends of the clamping plate 33 are fixedly connected to two turnover tables 50 respectively. The hydraulic rod 51 is fixedly connected to the turnover table 50, and the telescopic end of the hydraulic rod 51 is hingedly connected to one end of the arc-shaped pressing rod 52. The other end of the arc-shaped pressing rod 52 is in abutment with the clamping plate 33. One end of the rotating rod 53 is hingedly connected to the top of the hydraulic rod 51 near the clamping plate 33, and the other end of the rotating rod 53 is hingedly connected to the middle of the arc-shaped pressing rod 52.

[0050] The clamping mechanism 5 further comprises a first torsional spring 54, which is sleeved on the outer periphery of the rotating shaft of the turnover table 50, and the two ends of the first torsional spring 54 are fixedly connected to the turnover table 50 and the supporting rod 36 respectively.

[0051] The continuous feeding assembly 3 further comprises a hydraulic cylinder 37, a cutter 38 and a baffle 39. The hydraulic cylinder 37 is fixedly connected to the inner wall of the tower body 1, and the telescopic end of the hydraulic cylinder 37 is fixedly connected to the cutter 38. The cutter 38 and the baffle 39 are located on the two sides of the connecting part 151 respectively and are in abutment with each other. The baffle 39 is fixedly connected to one side of the discharge hopper 14.

[0052] The packaging bag 15 is made of soft material and can be folded and compressed. A plurality of packaging bags 15 can be connected end to end and wound on the supporting roller 30 through the bag body 150 and the connecting part 151, so as to realize storage and convenient folding and unfolding. After the waste falls into the packaging bag 15 through the discharge hopper 14 and is heat sealed, the hydraulic cylinder 37 drives the cutter 38 to move horizontally, and the connecting part 151 of the packaging bag 15 is cut by cooperating with the baffle 39. At the same time, the clamping mechanism 5 is loosened, the packaging bag 15 containing the waste is discharged downward through the waste outlet, and the operator can transfer and store it.

[0053] At this time, the clamping mechanism 5 loses the pulling force of the packaging bag 15, and the turnover table 50 is turned upward under the rebounding force of the first torsional spring 54, so that the clamping plate 33 is separated from the arc-shaped pressing rod 52 on both sides. Then the first motor 43 is started to drive the supporting roller 30 to rotate through the universal joint 31, so that the packaging bag 15 wound on the outer periphery of the supporting roller 30 falls downward to a suitable height. At the same time, the electric sliding table 35 is started to drive the supporting rod 36 to slide horizontally along the sliding rail 34 to the packaging bag 15. When the clamping plate 33 contacts the connecting part 151 of the packaging bag 15, the supporting rod 36 continues to move and the clamping plate 33 slides over the connecting part 151. At this time, the clamping plate 33 and the arc-shaped pressing rod 52 are located on the two sides of the connecting part 151 respectively. The hydraulic rod 51 is started to drive the one end of the arc-shaped pressing rod 52 to move, and the middle of the arc-shaped pressing rod 52 rotates around the rotating rod 53. The other end of the arc-shaped pressing rod 52 is turned over and abuts against the clamping plate 33 to clamp the connecting part 151. At this time, the two connecting parts 151 of the packaging bag 15 are fixed to the supporting roller 30 and the clamping mechanism 5 respectively.

[0054] Subsequently, the support rod 36 is slid back, the clamping mechanism 5 drives the two connecting parts 151 of the packaging bag 15 to move away from each other, and at the same time, due to the pulling of the packaging bag 15, the turnover table 50 is rotated from the vertical state to the horizontal state, the clamping mechanism 5 is changed from clamping from both sides to clamping from top to bottom, so as to unfold the packaging bag 15 from the folded and compressed state, and align the bag opening with the bottom opening of the discharge hopper 14, so as to prepare for the next packaging, realizing continuous packaging.
