Description

Technical Field

[0001] This utility model relates to the technical field of chemical waste gas treatment equipment, specifically a chemical waste gas treatment device. Background Technology

[0002] Chemical experiments typically generate chemical waste gases, which can have a certain impact on the health of personnel if left in the laboratory. While some chemical laboratories have ventilation systems, directly releasing toxic and harmful gases into the atmosphere can still pollute the air. Therefore, chemical waste gas treatment devices are needed to treat the waste gases before releasing them.

[0003] Publication number CN221580219U discloses a chemical waste gas treatment device. By setting up meshing gears and a gear ring, while the first stirring rod rotates around the rotating rod as an axis, the gear rotates along the gear ring, causing the first stirring rod to rotate. This, in turn, drives the second stirring rod to rotate around the first stirring rod as an axis, further improving the stirring effect on the liquid treatment agent inside the treatment tank. However, this patent still has the following problems in actual use:

[0004] By setting up meshing gears and gear rings, while the first stirring rod rotates around the rotating rod as an axis, the gears rotate along the gear ring, causing the first stirring rod to rotate. This, in turn, drives the second stirring rod to rotate around the first stirring rod as an axis, which can further improve the stirring effect on the liquid treatment agent inside the treatment tank. However, after prolonged use, the filter chamber needs to be replaced to ensure that it can purify the chemical waste gas. Currently, most filter chambers are installed with bolts, which may cause stripping of the bolts and screw holes when the filter chamber is frequently replaced.

[0005] A chemical waste gas treatment device is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a chemical waste gas treatment device to solve the problem mentioned in the background art. Currently, by setting up meshing gears and gear rings, the first stirring rod rotates around the rotating rod as an axis while the gears rotate along the gear ring, causing the first stirring rod to rotate. This, in turn, drives the second stirring rod to rotate around the first stirring rod as an axis, further improving the stirring effect on the liquid treatment agent inside the treatment tank. However, after prolonged use, the filter chamber needs to be replaced to ensure its ability to purify the chemical waste gas. Currently, most filter chambers are installed using bolts, which can lead to stripping of the bolts and threaded holes during frequent replacements.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a chemical waste gas treatment device, comprising a housing, wherein an air inlet pipe is connected through the surface of the housing near the bottom.

[0008] A water inlet and outlet pipe is connected through the other side surface of the box near the bottom. A valve is fixedly installed inside the water inlet and outlet pipe. A stirring assembly is set in the middle of the top surface of the box. A conveying pipe is connected through one side of the top surface of the box. A sealing sleeve is fitted on the top surface of the conveying pipe. A filter chamber is connected through the top surface of the sealing sleeve. An air outlet pipe is connected through the top surface of the filter chamber.

[0009] Also includes:

[0010] The sealing sleeve is provided with fixing components symmetrically on both sides;

[0011] The fixing component includes a sleeve that is connected through the sealing sleeve;

[0012] A tie rod is connected through the inside of the sleeve.

[0013] Preferably, a pull block is fixedly connected to one side surface of the pull rod, a torsion spring is sleeved on the surface of the pull rod, one side surface of the torsion spring is fixedly connected to a sleeve, and a sliding plate is fixedly connected to the other side surface of the torsion spring, with the sliding plate being connected through the pull rod.

[0014] Preferably, a limiting block is fixedly connected to the side surface of the sleeve away from the sealing sleeve.

[0015] Preferably, the stirring assembly includes a drive motor fixedly connected to the housing, and a rotating rod is fixedly connected to the output end of the drive motor through one side surface of the housing, with the bottom surface of the rotating rod rotatably connected to the housing.

[0016] Preferably, a plurality of stirring rods are rotatably connected around the surface of the rotating rod, and a gear is fixedly connected to the surface of the stirring rod away from the rotating rod, and a toothed plate is meshed with the bottom surface of the gear.

[0017] Preferably, the toothed plate is fixedly connected to the housing.

[0018] Preferably, the surface of the conveying pipe is provided with symmetrical slots on both sides, and the slots are engaged with the pull rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This chemical waste gas treatment device, by setting a stirring component, can improve the stirring effect of the liquid treatment agent, thereby improving the acid-base neutralization effect of the chemical waste gas. At the same time, by setting a fixing component, the filter chamber can be easily disassembled, making it convenient to replace the filter elements inside the filter chamber, thereby ensuring the filtration efficiency of the chemical waste gas. The specific details are as follows:

[0020] 1. By setting a fixed component, when the filter chamber needs to be replaced, pulling the pull block causes the pull rod to move. The movement of the pull rod causes the slide plate to move, which in turn compresses the torsion spring, causing it to deform. After the pull block moves the pull rod to a certain position, the pull rod separates from the slot, allowing the filter chamber and air outlet pipe to be disassembled. This allows for the replacement of the filter element inside the filter chamber. Furthermore, after the pull block moves to a certain position, with its bottom exceeding the top of the limit block, rotating the pull block causes the torsion spring and slide plate to rotate as well. Rotating the pull block 180 degrees causes its bottom to be positioned... After the top of the limiting block is above, the pulling force on the pull block is loosened, so that the bottom of the pull block fits against the top of the limiting block under the action of the torsion spring. This can limit the pull block and the pull rod, making it easier to replace the filter element inside the filter chamber later. When installing the filter chamber, after the sealing sleeve on the filter chamber is fitted onto the conveying pipe, the pull block is rotated 180 degrees again to make the pull block and the limiting block misaligned. This allows the slide plate to return to its original position under the action of the torsion spring. At the same time, the slide plate and the pull rod are fixedly connected through the plate. After the slide plate returns to its original position, the pull rod also returns to its original position, so that the pull rod and the slot are re-engaged. This completes the installation of the filter chamber and the exhaust pipe, ensuring the filtration efficiency of the chemical waste gas.

[0021] 2. By setting up a stirring assembly, after the waste gas and liquid treatment agent are poured into the tank, the drive motor is started via the control terminal. The output of the drive motor drives the rotating rod to rotate, which in turn drives the stirring rod to rotate, causing the stirring rod to perform a circular motion. Simultaneously, the rotation of the stirring rod drives the rotation of the gears. The gears are meshed with the gear plate, and the stirring rod is rotatably connected to the rotating rod. This causes the gears to move on the gear plate, and the meshing relationship between the gear plate and the gears causes the gears to rotate, which in turn drives the stirring rod to rotate. Thus, the stirring rod rotates on its own axis while simultaneously revolving around the central axis, thereby improving the stirring effect of the liquid treatment agent and enhancing the acid-base neutralization effect of the chemical waste gas.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5The present invention provides a technical solution: a chemical waste gas treatment device, including a box 1, an air inlet pipe 2 is connected through one side surface of the box 1 near the bottom; an inlet and outlet water pipe 3 is connected through the other side surface of the box 1 near the bottom, a valve 4 is fixedly installed inside the inlet and outlet water pipe 3, a stirring assembly 5 is arranged in the middle of the top surface of the box 1, a conveying pipe 6 is connected through one side of the top surface of the box 1, a sealing sleeve 7 is fitted on the top surface of the conveying pipe 6, a filter chamber 8 is connected through the top surface of the sealing sleeve 7, and an air outlet pipe 9 is connected through the top surface of the filter chamber 8.

[0030] It also includes: symmetrically arranged fixing components 10 on both sides of the sealing sleeve 7; wherein, the fixing component 10 includes a sleeve 1001 that is connected through to the sealing sleeve 7; wherein, a pull rod 1002 is connected through to the inside of the sleeve 1001, such as... Figure 1-5 As shown, by setting the stirring component 5, the stirring effect of the liquid treatment agent can be improved, thereby improving the acid-base neutralization effect of the chemical waste gas. At the same time, by setting the fixing component 10, the filter chamber 8 can be easily disassembled, making it easy to replace the filter element inside the filter chamber 8, thereby ensuring the filtration efficiency of the chemical waste gas.

[0031] A pull block 1003 is fixedly connected to one side surface of the pull rod 1002. A torsion spring 1004 is sleeved on the surface of the pull rod 1002. One side surface of the torsion spring 1004 is fixedly connected to the sleeve 1001. A sliding plate 1005 is fixedly connected to the other side surface of the torsion spring 1004. The sliding plate 1005 is connected through the pull rod 1002. A limit block 1006 is fixedly connected to the side surface of the sleeve 1001 away from the sealing sleeve 7. Figure 4As shown, when the filter chamber 8 needs to be replaced, pulling the pull block 1003 causes the pull rod 1002 to move. The movement of the pull rod 1002 causes the sliding plate 1005 to move, which in turn compresses the torsion spring 1004, causing it to deform. After the pull block 1003 moves the pull rod 1002 to a certain position, the pull rod 1002 separates from the slot 11, allowing the filter chamber 8 and the air outlet pipe 9 to be disassembled. This allows the filter element inside the filter chamber 8 to be replaced. Simultaneously, after the pull block 1003 moves to a certain position, the filter element... After the bottom of the pull block 1003 exceeds the top of the limit block 1006, by rotating the pull block 1003, the rotation of the pull block 1003 can also drive the rotation of the torsion spring 1004 and the slide plate 1005. At the same time, after rotating the pull block 1003 180 degrees, the bottom of the pull block 1003 is above the top of the limit block 1006. By loosening the pulling force on the pull block 1003, the bottom of the pull block 1003 is in contact with the top of the limit block 1006 under the action of the torsion spring 1004. This can limit the pull block 1003 and the pull rod 1002, thus facilitating the subsequent replacement of the filter element inside the filter chamber 8.

[0032] The stirring assembly 5 includes a drive motor 501 fixedly connected to the housing 1. A rotating rod 502 is fixedly connected to one side surface of the housing 1 through the output end of the drive motor 501. The bottom surface of the rotating rod 502 is rotatably connected to the housing 1. Several stirring rods 503 are rotatably connected around the surface of the rotating rod 502. A gear 504 is fixedly connected to the side surface of each stirring rod 503 away from the rotating rod 502. A toothed plate 505 is meshed with the bottom surface of the gear 504. The toothed plate 505 is fixedly connected to the housing 1. Figure 2 , 5As shown, the drive motor 501 is started via the control terminal, causing its output to rotate the rotating rod 502. This rotation of the rotating rod 502, in turn, drives the stirring rod 503 to rotate, resulting in circular motion of the stirring rod 503. Simultaneously, the rotation of the stirring rod 503 drives the rotation of the gear 504. The gear 504 is meshed with the gear plate 505, and the stirring rod 503 is rotatably connected to the rotating rod 502. This ensures that the rotation of the stirring rod 503 drives the gear 504. The gear moves on the toothed plate 505, and the meshing relationship between the toothed plate 505 and the gear 504 causes the gear 504 to rotate, which in turn drives the stirring rod 503 to rotate. This allows the stirring rod 503 to rotate while revolving around the sun, thereby improving the stirring effect of the liquid treatment agent and enhancing the acid-base neutralization effect of the chemical waste gas. At the same time, the gear 504 and the toothed plate 505 can be coated with anti-corrosion and anti-rust paint according to the actual situation, thereby indirectly increasing the service life of the gear 504 and the toothed plate 505.

[0033] The surface of the conveying pipe 6 is symmetrically provided with slots 11 on both sides. The slots 11 are engaged with the pull rod 1002. Figure 4 As shown, the pull rod 1002 is re-engaged with the slot 11 to complete the installation of the filter chamber 8 and the exhaust pipe 9, thereby ensuring the filtration efficiency of the chemical waste gas.

[0034] Working principle: Before using this type of chemical waste gas treatment device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5As shown, by first setting the fixing component 10, when the filter chamber 8 needs to be replaced, by pulling the pull block 1003, the pull block 1003 will drive the pull rod 1002 to move. The movement of the pull rod 1002 will drive the slide plate 1005 to move, thereby causing the slide plate 1005 to compress the torsion spring 1004, causing the torsion spring 1004 to deform. At the same time, after the pull block 1003 drives the pull rod 1002 to move a certain position, the pull rod 1002 will engage with the slot. 11. Separation allows the filter chamber 8 and air outlet pipe 9 to be disassembled, enabling the replacement of the filter element inside the filter chamber 8. Simultaneously, after the pull block 1003 moves to a certain position, with its bottom exceeding the top of the limit block 1006, rotating the pull block 1003 causes the torsion spring 1004 and the sliding plate 1005 to rotate. Furthermore, rotating the pull block 1003 180 degrees allows the pull block 100... After the bottom of 3 is positioned above the top of the limiting block 1006, by loosening the pulling force on the pull block 1003, the bottom of the pull block 1003 is brought into contact with the top of the limiting block 1006 under the action of the torsion spring 1004. This allows the pull block 1003 and the pull rod 1002 to be positioned, facilitating subsequent replacement of the filter elements inside the filter chamber 8. When installing the filter chamber 8, after fitting the sealing sleeve 7 on the filter chamber 8 onto the conveying pipe 6, the filter chamber 8 is then... After rotating the pull block 1003 180 degrees, the pull block 1003 is displaced from the limit block 1006, causing the slide plate 1005 to return to its original position under the action of the torsion spring 1004. At the same time, the slide plate 1005 and the pull rod 1002 are fixedly connected through the slide plate 1005. After the slide plate 1005 returns to its original position, the pull rod 1002 also returns to its original position, so that the pull rod 1002 and the slot 11 are re-engaged, thereby completing the installation of the filter chamber 8 and the exhaust pipe 9, thus ensuring the filtration efficiency of the chemical waste gas.

[0035] Secondly, by setting up the stirring assembly 5, after the waste gas and liquid treatment agent are poured into the tank 1, the drive motor 501 is started through the control terminal, so that the output end of the drive motor 501 can drive the rotation of the rotating rod 502. The rotation of the rotating rod 502 can drive the rotation of the stirring rod 503, so that the stirring rod 503 performs a circular motion. At the same time, when the stirring rod 503 rotates, it will drive the gear 504 to rotate. The gear 504 is meshed with the toothed plate 505, and the stirring rod 503 is rotatably connected to the rotating rod 502. This means that when the stirring rod 503 rotates, it will drive the gear 504 to move on the toothed plate 505. The meshing relationship between the toothed plate 505 and the gear 504 causes the gear 504 to rotate, which in turn drives the stirring rod 503 to rotate. Thus, the stirring rod 503 can rotate on its own axis while revolving around the central axis, thereby improving the stirring effect of the liquid treatment agent and improving the acid-base neutralization effect of the chemical waste gas.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
