Description

Technical Field

[0001] This utility model relates to the technical field of waste gas absorption devices, specifically a waste gas absorption device for the preparation of gluconate. Background Technology

[0002] Glycolyl glycolate, also known as isopentoxyethyl allyl acetate or (3-methylbutoxy)acetic acid-2-propenol ester, is a chemical substance with the molecular formula C10H18O3 and a molecular weight of 186.2481, used in everyday fragrances. Glycolyl glycolate is a colorless, transparent liquid with a strong fruity, green, galbanum, and pineapple aroma. These aroma characteristics make galbanyl glycolate very useful in formulating everyday fragrances, adding a modern touch. However, the production of galbanyl glycolate generates waste gas. Since its production involves chemical reactions, these reactions typically produce byproducts such as waste gas, wastewater, and solid waste. Therefore, the waste gas generated during its production requires treatment.

[0003] According to a waste gas absorption device for the preparation of gluconate with application number 202420833206.1, when replacing activated carbon, a new square shell is taken out and inserted into the middle shell from top to bottom. The magnet at the bottom of the new square shell magnetically attracts the metal plate at the top of the old square shell. Pulling two pull plates by hand causes the insertion rod to retract, thus releasing the fixation of the old square shell. Pushing the new square shell downward causes the old square shell to move downward as well. Under the action of magnetic force, it will not fall off until the new square shell has completely moved to the original position of the old square shell. The reset spring resets and pushes the pull plate to insert the insertion rod into the limiting holes on both sides inside the middle shell, thus fixing the new square shell. This completes the replacement of the square shell and thus refreshes the activated carbon inside.

[0004] However, the aforementioned waste gas absorption device for guar gum preparation has certain shortcomings. The middle shell of the device is hollow, and the replacement square shell is slidably connected to the middle shell. Consequently, gaps inevitably exist at the connection point. When guar gum waste gas is absorbed and treated, and when the activated carbon in the middle shell is replaced, the waste gas may overflow from the connection point between the middle shell and the square shell. When the activated carbon is replaced, gaps also exist in the activated carbon, and the waste gas may also overflow. This waste gas overflow may be inhaled by workers when they replace the activated carbon, which may affect their health. Therefore, we propose a waste gas absorption device for guar gum preparation.

[0011] Preferably, a limiting pin is inserted inside the handle turntable, and a limiting hole is formed inside one side of the processing tube, with the limiting pin cooperating with the limiting hole.

[0012] This utility model provides a waste gas absorption device for the preparation of glucono-delta-lactone, which has the following beneficial effects:

[0013] 1. This waste gas absorption device for the preparation of glucono-delta-lactone comprises a partition, a first treatment chamber, a second treatment chamber, a through groove, a side groove, a threaded rod, a valve plate, a handle turntable, a limiting guide plate, a slot, and a mounting frame. With the first and second treatment chambers respectively provided, when the mounting frame in the first treatment chamber needs to be replaced, the handle turntable can be rotated to drive the threaded rod to rotate, thereby moving the valve plate through the thread to the first treatment chamber on one side of the partition to seal it. This effectively prevents untreated waste gas from entering the first treatment chamber, allowing for subsequent replacement of the mounting frame. Simultaneously, it does not affect the waste gas absorption and treatment in the second treatment chamber, and prevents waste gas overflow, thus avoiding the inhalation of waste gas by personnel replacing the mounting frame and causing harm, resulting in higher safety.

[0014] 2. The waste gas absorption device for the preparation of glucono-delta-lactone, through the arrangement of a sealing plate, a fixing plate, a sliding groove, a sliding rod, a sliding plate, a pin, a pin groove, a first spring, a pull plate, a positioning groove, and a second spring, facilitates the installation and fixation of the mounting frame and subsequent disassembly and replacement. When installing the mounting frame, after inserting the mounting frame into the slot, pushing the sealing plate will cause one side of the mounting frame to be inserted into the positioning groove, compressing the second spring. At the same time, the pin will be locked into the pin groove, thus fixing and limiting the sealing plate. When disassembly is required, the pull plate must be pulled to remove the pin from the pin groove, which will release the limitation on the sealing plate. At the same time, the second spring will rebound and push the mounting frame out of the slot, making it easy for the staff to remove it. The overall installation and disassembly are relatively convenient and quick. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a waste gas absorption device for the preparation of glucono-delta-lactone, including a treatment pipe 1, a partition 2 fixedly installed in the middle of the treatment pipe 1, a first treatment chamber 3 provided inside the treatment pipe 1 and on one side of the partition 2, a second treatment chamber 4 provided inside the treatment pipe 1 and on the other side of the partition 2, a through groove 5 opened inside the partition 2, and side grooves 6 opened inside both sides of the treatment pipe 1, a threaded rod 7 rotatably installed inside the side groove 6, a valve plate 8 installed on the surface of the threaded rod 7, the valve plate 8 cooperating with the threaded rod 7, and a handle fixedly installed at one end of the threaded rod 7 extending to the outside of the treatment pipe 1. The inside of the handle turntable 9 is fitted with a limit pin. The inside of one side of the processing tube 1 is opened with a limit hole. The limit pin and the limit hole cooperate. Two limit guide plates 10 are fixedly installed on the inner walls of both sides of the first processing chamber 3 and the second processing chamber 4. The valve plate 8 cooperates with the limit guide plates 10. Slots 11 are opened inside both sides of the processing tube 1. The mounting frame 12 is inserted into the inside of the slot 11. The activated carbon filter screen 13 is set inside the mounting frame 12. The top and bottom of the slot 11 are opened inside the processing tube 1. The sealing strip 15 is fixedly installed inside the mounting groove 14. The sealing strip 15 cooperates with the mounting frame 12.

[0024] The sealing strip 15 is used to improve the sealing of the mounting frame 12 inside the slot 11, and to prevent the exhaust gas generated during the preparation of galvanized ester from overflowing from the slot 11. The limiting guide plate 10 is used to guide the valve plate 8 and also to improve the sealing of the valve plate 8 when it is closed in the first processing chamber 3 or the second processing chamber 4. The limiting pin in the handle turntable 9 is used to fix and limit the handle turntable 9.

[0025] A sealing plate 16 is fixedly installed on one side of the mounting frame 12. Two fixing plates 17 are fixedly installed on both sides of the processing pipe 1. The fixing plate 17 has a sliding groove 18 inside. A sliding rod 19 is slidably installed inside the sliding groove 18. A sliding plate 20 is fixedly installed at one end of the sliding rod 19. A pin 21 is fixedly installed at the bottom of the sliding plate 20. The top and bottom of the sealing plate 16 have pin grooves 22 inside. The pin 21 cooperates with the pin groove 22. A first spring 23 is installed on the outside of the sliding rod 19. A pull plate 24 is fixedly installed at the other end of the sliding rod 19. Positioning grooves 25 are opened inside both sides of the partition plate 2. The mounting frame 12 cooperates with the positioning groove 25. A second spring 26 is fixedly installed on one side inside the positioning groove 25. The mounting frame 12 cooperates with the second spring 26. One side of the pin 21 has an inclined surface that cooperates with the sealing plate 16, so that when the sealing plate 16 contacts the pin 21, it is pushed to move and then stuck into the pin groove 22.

[0026] A fan 27 is installed at the top of both the first processing chamber 3 and the second processing chamber 4. A check valve 28 is installed inside the processing pipe 1, and a connecting flange 29 is installed at the bottom of the processing pipe 1. When the mounting frame 12 in the first processing chamber 3 needs to be disassembled and replaced, the fan 27 inside it needs to be turned off. Similarly, when the mounting frame 12 in the second processing chamber 4 needs to be replaced, the fan 27 inside it also needs to be turned off. The function of the check valve 28 is to prevent the backflow of exhaust gas.

[0027] In summary, when using this waste gas absorption device for the preparation of glucono-delta-lactone, if it is necessary to disassemble and replace the mounting frame 12 in the first treatment chamber 3, firstly, pull out the limiting pin in the handle turntable 9 to release the limitation on the handle turntable 9. Then, by rotating the threaded rod 7 through the handle turntable 9, the valve plate 8 will be moved through the threaded displacement, allowing the valve plate 8 to pass through the through groove 5 and enter the inner side of the first treatment chamber 3 to seal the first treatment chamber 3. Then, the fan 27 in the first treatment chamber 3 is turned off while the fan 27 in the second treatment chamber 4 is turned on, and the waste gas can be absorbed and treated through the second treatment chamber 4 without stopping the machine. If the exhaust gas treatment efficiency is affected, the mounting frame 12 can be disassembled and replaced. When disassembling, pull the pull plate 24 to pull the pin 21 out of the pin groove 22, which will release the restriction on the sealing plate 16. At the same time, the second spring 26 will rebound and push the mounting frame 12 out of the slot 11. Then, the mounting frame 12 can be pulled out of the slot 11. The new mounting frame 12 is then inserted into the first treatment cavity 3 through the slot 11, so that one side of the mounting frame 12 is inserted into the positioning groove 25 to squeeze the second spring 26. At the same time, the pin 21 is inserted into the pin groove 22, which can fix and limit the sealing plate 16, thus completing the replacement.
