Detailed implementation manners

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0046] An embodiment of the present application provides an acid liquid filling and capping machine, which can solve the problem of potential safety hazards for workers in the related art.

[0047] Please refer to Figures 1 to 15 , an acid liquid filling and capping machine, which includes:

[0048] In the present application, the process of filling the reagent bottle with acid liquid needs to be carried out first, that is, the reagent bottle enters the acid liquid filling area for acid liquid filling, and then the reagent bottle is transported by the conveyor belt 2 and enters the position calibration area of the reagent bottle. After the position of the reagent bottle is calibrated, the reagent bottle needs to be transported to the capping area by the conveyor belt 2 for capping treatment;

[0049] In the present application, the acid liquid filling area includes a workbench 1, a conveyor belt 2, a placing member 5, a pushing plate 6, a second fixing frame 7 and a filling structure 8. The workbench 1 is provided with a conveyor belt 2, and the conveyor belt 2 provides a stable conveying path. The placing member 5 includes a placing table 51 and a frame 52. The frame 52 is connected to the workbench 1, and the placing table 51 is connected to the frame 52. The placing table 51 and the conveyor belt 2 are on the same horizontal plane. The pushing plate 6 is slidably connected to the workbench 1, and the moving direction of the pushing plate 6 is perpendicular to the moving direction of the conveyor belt 2. The second fixing frame 7 is connected to the workbench 1. The filling structure 8 further includes a filling pipe 81 and a second lifting frame 82. The second lifting frame 82 is connected to the workbench 1, and the second lifting frame 82 is slidably connected to the second fixing frame 7. The filling pipe 81 is located above the placing table 51.

[0050] During the acid liquid filling process, the workbench 1 and the conveyor belt 2 provide a stable conveying path to ensure that the reagent bottle can move smoothly. The placing member 5 ensures that the reagent bottle remains stable during the filling process and avoids liquid leakage caused by the shaking of the reagent bottle. The pushing plate 6 can adjust the position of the reagent bottle and push the reagent bottle from the conveyor belt 2 onto the placing table 51. The second fixing frame 7 and the second lifting frame 82 ensure that before the reagent bottle is pushed onto the placing table 51, the filling pipe 81 does not obstruct the movement of the reagent bottle, and after the reagent bottle is pushed onto the placing table 51, the filling pipe 81 can be inserted into the reagent bottle for filling. Through the above technical means, even if liquid leakage occurs during the filling process of the reagent bottle, the acid liquid will not drip onto the conveyor belt 2, thus effectively solving the problem of liquid leakage during the acid liquid filling process.

[0051] After the acid solution is manufactured, it is stored in a storage tank. Then, the acid solution is extracted from the storage tank and poured into reagent bottles on conveyor belt 2. Finally, a sealing plug is installed on the reagent bottle to prevent the acid solution in the reagent bottle from leaking. During the process of pouring the acid solution into the reagent bottle, there may be a situation where the acid solution is not completely aligned or splashes out of the reagent bottle, resulting in the acid solution dripping onto conveyor belt 2 and causing corrosion of conveyor belt 2. To avoid this situation, the pouring structure 8 in the present invention is designed with a second lifting frame 82 and a pouring pipe 81 to ensure the accuracy of the filling process.

[0052] Further, the present application also proposes that an introduction hole 53 is provided above the frame 52, and the pouring pipe 81 is slidably connected to the introduction hole 53; there is a placement space on the placement table 51 for pouring the acid solution into the reagent bottle. When the reagent bottle is placed in the placement space, the mouth of the reagent bottle corresponds to the introduction hole 53.

[0053] Through the above technical means, the claims solve the problem of how to ensure that the acid solution accurately enters the reagent bottle when pouring the acid solution. The sliding connection between the introduction hole 53 and the pouring pipe 81 ensures that the pouring pipe 81 can be flexibly adjusted in position, while the placement space on the placement table 51 ensures the stability and position accuracy of the reagent bottle, thus effectively avoiding the problem of acid solution overflow. An introduction hole 53 is provided above the frame 52, and the pouring pipe 81 is slidably connected to the introduction hole 53. This design ensures that the pouring pipe 81 can accurately align with the mouth of the reagent bottle, thus avoiding acid solution overflow or deviation; there is a placement space on the placement table 51 for pouring the acid solution into the reagent bottle, ensuring that the reagent bottle remains stable during the filling process and will not cause acid solution to spill due to position deviation; when the reagent bottle is placed in the placement space, the mouth of the reagent bottle corresponds to the introduction hole 53. This design ensures that the acid solution can be accurately poured into the reagent bottle, reducing waste of the acid solution and corrosion of conveyor belt 2.

[0054] Further, the present application also proposes that the placement member 5 further includes a baffle 54; the baffle 54, the frame 52, and the back plate 57 surround the storage space on the bottom plate 56, and the storage space communicates with the placement space.

[0055] The placement member 5 includes a baffle 54, a frame 52, and a placement table 51. There is a storage space on the bottom plate 56 for collecting the acid solution splashed out from the reagent bottle. The storage space communicates with the placement space of the reagent bottle, enabling the splashed acid solution to be effectively collected. Through the combination of these technical features, the problem of the acid solution dripping onto conveyor belt 2 and causing corrosion of conveyor belt 2 is solved. The storage space formed by the baffle 54, the frame 52, and the placement table 51 can effectively collect the splashed acid solution, thereby protecting conveyor belt 2 from being corroded by the acid solution.

[0056] Specifically, the baffle 54 can be made of acid-resistant material to ensure that it will not be corroded by acid solution during long-term use. The design of the frame 52 can take into account the stable connection with the workbench 1 to ensure the stability of the entire placement member 5. The placement table 51 can be designed as multiple rollers to facilitate the movement of reagent bottles and enable the splashed acid solution to flow smoothly into the storage space.

[0057] Furthermore, the present application also proposes that the placement member 5 further includes an outlet pipe 55. One end of the outlet pipe 55 is communicated with the storage space, and the other end of the outlet pipe 55 is an opening.

[0058] The placement member 5 includes an outlet pipe 55. One end of this outlet pipe 55 is communicated with the storage space, and the other end is an opening. The function of the outlet pipe 55 is to export the leaked liquid in the storage space, thereby realizing the recovery of the leaked liquid. By adding the outlet pipe 55 to the placement member 5, when the acid solution leaks during the filling process, the leaked liquid will be collected by the storage space and then exported through the outlet pipe 55, thus solving the problem of the recovery of the leaked liquid during the acid solution filling process;

[0059] It should be noted that during the process of the acid solution dripping from the placement space to the storage space, it will drip on the convex platform 59, and the acid solution will slide from the convex platform 59 into the collection tank 58. Since the bottom plate 56 is inclined as a whole, the acid solution in the collection tank 58 will slide towards the outlet pipe 55, improving the efficiency of the acid solution entering the outlet pipe 55.

[0060] Furthermore, the present application also proposes that a first hydraulic press 9 is provided on the workbench 1, and the output end of the first hydraulic press 9 is connected to the push plate 6; a mating groove is provided on the side of the push plate 6 facing the placement space, and the mating groove matches the outer wall of the reagent bottle.

[0061] A first hydraulic press 9 is provided on the workbench 1, and the output end of the first hydraulic press 9 is connected to the push plate 6. A mating groove is provided on the side of the push plate 6 facing the placement space, and the mating groove matches the outer wall of the reagent bottle. These technical features cooperate with each other. Before the filling process, the reagent bottle is pushed onto the placement table 51, and the mating groove prevents the reagent bottle from shifting during the pushing process, enabling the reagent bottle to be accurately aligned with the filling position after being pushed, reducing the possibility of liquid leakage, and thus solving the problem of liquid leakage during the reagent bottle filling process. Through the above technical means, the first hydraulic press 9 drives the push plate 6 to move, accurately positioning the reagent bottle at the filling position, and the matching of the mating groove with the outer wall of the reagent bottle further ensures the stability of the reagent bottle.

[0062] Furthermore, the present application also proposes that a pushing structure 10 is further included. The pushing structure 10 includes a limiting plate 101 and a second hydraulic press 102; the second hydraulic press 102 is connected to the second fixing frame 7, the output end of the second hydraulic press 102 is connected to the limiting plate 101, and the limiting plate 101 is located in the limiting space.

[0063] In the pushing structure 10, the limiting plate 101 and the second hydraulic press 102 cooperate with each other. The limiting plate 101 restricts the position of the reagent bottle, enabling the reagent bottle to remain in the correct position after being pushed. The second hydraulic press 102 provides a driving force to ensure that the limiting plate 101 can move in a timely manner, thereby achieving the precise positioning and stable filling of the reagent bottle. At the same time, after the filling is completed, the limiting plate 101 can push the reagent bottle back from the placement table 51 to the conveyor belt 2. Through the above solution, the problems of precise filling of acid liquid and prevention of acid liquid overflow during the filling process of the reagent bottle are solved, and the reagent bottle can be pushed back to the conveyor belt 2 after the filling is completed to continue the next process.

[0064] Furthermore, the present application also proposes that the filling structure 8 further includes a second screw 83 and a mounting frame 84. The mounting frame 84 is connected to the second fixing frame 7, and the second screw 83 is rotatably connected to the mounting frame 84. The second screw 83 cooperates with the second lifting frame 82.

[0065] The filling structure 8 includes technical features such as a second screw 83, a mounting frame 84, a second fixing frame 7, and a second lifting frame 82. Through the rotational connection of the second screw 83 with the mounting frame 84, the lifting control of the second lifting frame 82 is achieved, so that the position of the filling pipe 81 can be accurately adjusted to ensure that the acid liquid is accurately filled into the reagent bottle. The connection between the mounting frame 84 and the second fixing frame 7 provides stable support, ensuring the smooth operation of the second screw 83 and the second lifting frame 82. Through the mutual cooperation of these technical features, the lifting control problem of the filling structure 8 is solved, and the filling accuracy and stability are improved.

[0066] The second screw 83 drives the second lifting frame 82 to move up and down, enabling the filling pipe 81 to accurately align with the mouth of the reagent bottle, avoiding the situation of acid liquid splashing or dripping onto the conveyor belt 2. The connection between the mounting frame 84 and the second fixing frame 7 can be achieved by bolt connection, welding, etc. to ensure the firmness and stability of the structure. The cooperation between the second screw 83 and the second lifting frame 82 can be realized by screw connection to facilitate the smooth lifting of the second lifting frame 82. In addition, the material of the second screw 83 can be selected as a corrosion-resistant material to meet the environmental requirements of acid liquid filling.

[0067] After the reagent bottle is filled with acid solution, the reagent bottle is transported through the conveyor belt 2 and enters the position calibration area of the reagent bottle. The position calibration area contains a clamping device 11, a calibration device 12, and a pre-positioning device 13. The clamping device 11 corresponds to the capping device. When the clamping device 11 closes, the mouth of the reagent bottle matches the capping device. Specifically, the calibration device 12 includes a calibration rod 121, an assembly block 122, and an adjustment knob 123. The number of calibration rods 121 is at least three. The calibration rods 121 are arranged along the X, Y, and Z axes. The assembly block 122 is provided with through holes perpendicular to each other. The assembly block 122 is sleeved on the calibration rod 121 so that adjacent two calibration rods 121 are perpendicular to each other. The calibration device 12 further includes an adjustment knob 123. The adjustment knob 123 is screwed into the assembly block 122. The end of the adjustment knob 123 abuts against the calibration rod 121.

[0068] The clamping devices 11 are respectively arranged on both sides of the conveying track. The clamping device 11 includes a cylinder 111 and a positioning claw 112. The extending end of the cylinder 111 is connected to the positioning claw 112. The extending ends of the cylinders 111 are arranged oppositely so that the positioning claws 112 close. The positioning claw 112 is attached to one of the calibration rods 121. Among them, the positioning claw 112 includes a bottle body claw 1121, a bottle mouth claw 1122, and a connecting rod 1123. The bottle mouth claw 1122 corresponds to the mouth of the reagent bottle. The bottle body claw 1121 corresponds to the body of the reagent bottle. The bottle body claw 1121 is connected to the cylinder 111. One end of the connecting rod 1123 is connected to the bottle mouth claw 1122, and the other end is connected to the bottle body claw 1121; the connecting rod 1123 is arranged in the vertical direction; the connecting rod 1123 is attached to one of the calibration rods 121.

[0069] The pre-positioning device 13 is arranged on one side of the clamping device 11 so that the conveying direction of the conveying track points from the pre-positioning device 13 to the clamping device 11. The pre-positioning device 13 includes a chuck 131 and a stepping motor 132. The chuck 131 is connected to the output end of the stepping motor 132. The chuck 131 is provided with a plurality of card slots corresponding to the body of the reagent bottle. The card slots are arranged circumferentially along the chuck 131.

[0070] In actual application, the relative position relationship between the capping device and the clamping device 11 is measured in advance. Subsequently, the position of the calibration rod 121 is adjusted according to the measured relative position. By rotating the adjustment knob 123 to disengage the adjustment knob 123 from the calibration rod 121, the sliding assembly block 122 can be slid, thereby adjusting the relative position between the calibration rods 121. Since the through holes formed in the assembly block 122 are perpendicular to each other, the calibration rods 121 can still maintain a perpendicular state during the sliding process. When the calibration rod 121 is adjusted to the specified position, the adjustment knob 123 is tightened so that the adjustment knob 123 abuts against the calibration rod 121, thereby fixing the assembly block 122 by the frictional force between the adjustment knob 123 and the calibration rod 121, and further fixing the position of the calibration rod 121. Thus, the calibration rods 121 are arranged along the X, Y, and Z axes. By adjusting the position of the calibration rod 121, a reference point can be determined in space, and this reference point matches the capping device. The connecting rod 1123 is also arranged in the vertical direction. By making one of the calibration rods 121 fit with the connecting rod 1123, the position of one of the clamping devices 11 can be made to match the reference point, and further match the capping device.

[0071] During operation, the conveying track continuously conveys reagent bottles. When the reagent bottle moves to the pre-positioning device 13 driven by the conveying track, the chuck 131 is in a rotating state driven by the stepping motor 132, so that the reagent bottle can enter the card slot on the chuck 131. Thus, the two chucks 131 will hold the reagent bottle on both the left and right sides of the reagent bottle, and further perform a preliminary positioning of the position of the reagent bottle. Subsequently, driven by the stepping motor 132, the chuck 131 continues to rotate, so as to release the chuck 131 to the clamping device 11. Thus, by using the pre-positioning device 13, on the one hand, the reagent bottle is preliminarily positioned, and on the other hand, the mutually attached reagent bottles are separated, so as to facilitate the subsequent clamping device 11 to perform clamping.

[0072] When the conveying track conveys the reagent bottle to the clamping device 11, the cylinder 111 performs corresponding actions, so that the positioning claws 112 are mutually held. Among them, the bottle body claws 1121 and the bottle mouth claws 1122 act synchronously under the connection of the connecting rod 1123, thereby simultaneously pushing the bottle body and the bottle mouth of the reagent bottle. Thus, the final positioning of the position of the reagent bottle is performed. Through the foregoing adjustment process, the position of one of the clamping devices 11 has been matched with the reference point position, that is, matched with the capping device. Then, during the positioning process, the positioning claws 112 of the other clamping device 11 can be made to approach this clamping device 11. It is also possible to preset the action parameters of the cylinders 111 of the two clamping devices 11 by using the already determined reference point. Thus, through the foregoing action process, the bottle mouth of the reagent bottle can be made to match the capping device, so that the process of assembling the bottle cap can proceed normally.

[0073] After the position of the reagent bottle is calibrated, the reagent bottle is moved to the capping area, which includes a workbench 1 and a capping structure 3. A conveyor belt 2 is provided on the workbench 1, and there is a capping area for placing the reagent bottle on the conveyor belt 2. The capping structure 3 includes a first fixing frame 31, a first lifting frame 32, and a capping member 33. The first fixing frame 31 is connected to the workbench 1. The first lifting frame 32 is slidably connected to the first fixing frame 31, and the capping member 33 is provided on the first lifting frame 32. When the reagent bottle is placed in the capping area, the position of the capping member 33 corresponds to the position of the mouth of the reagent bottle. The capping structure 3 further includes a second motor 312, which is connected to the first lifting frame 32, and the output end of the second motor 312 is connected to the capping member 33;

[0074] After the acid solution is poured into the reagent bottle, the reagent bottle moves on the conveyor belt 2. After the position of the reagent bottle is calibrated, the reagent bottle needs to be capped. In this application, the capping operation is carried out in two steps. The first step is to use a rubber stopper to perform the first layer of sealing inside the mouth of the bottle, and the second step is to use a screw cap to perform the second layer of sealing outside the mouth of the reagent bottle. That is, there are two capping structures 3 and a hoist 4 in this application. First, perform the first layer of sealing of the reagent bottle. Lift the capping member 33 through the first lifting frame 32, then move the reagent bottle to the capping area for the first layer of sealing, and then fix the reagent bottle through the bottle body claw 1121 and the bottle mouth claw 1122. Put a rubber stopper on the capping member 33, lower the capping member 33 through the first lifting frame 32, and insert the rubber stopper into the mouth of the reagent bottle to complete the first layer of sealing of the reagent bottle. After that, start the second sealing of the reagent bottle. Therefore, it is necessary to use the second capping structure 3 and the second hoist 4. First, lift the capping member 33 through the first lifting frame 32, then put a screw cap on the capping member 33, transport the reagent bottle to the capping area through the conveyor belt 2, and fix the reagent bottle through the bottle body claw 1121. Control the capping member 33 to lower through the first lifting frame 32 until the screw cap touches the mouth of the reagent bottle. At this time, through the second motor 312 and the first lifting frame 32 continue to press down, and connect the screw cap to the outside of the mouth of the reagent bottle through the thread to complete the second sealing of the mouth of the reagent bottle.

[0075] In this application, two sets of capping structures 3 and hoists 4 are used to package the reagent bottle filled with acid solution, avoiding the problem that staff need to operate and come into contact with the acid solution.

[0076] Further, in this embodiment, the capping structure 3 further includes a slide rail 34, a bracket 35, a cover plate, a third hydraulic press 37, and a cover groove 38. The bracket 35 is connected to the first fixing frame 31. The slide rail 34 has openings at both ends. One end of the slide rail 34 is connected to the bracket 35. The third hydraulic press 37 is disposed on the bracket 35. The output end of the third hydraulic press 37 is connected to the drag cover plate 36. The drag cover plate 36 is provided with a cover groove 38 for placing a capping. The drag cover plate 36 has a first position and a second position. When the drag cover plate 36 is in the first position, the cover groove 38 communicates with the slide rail 34. When the drag cover plate 36 is in the second position, the position of the cover groove 38 corresponds to the position of the capping member 33, and the drag cover plate 36 blocks one end of the slide rail 34.

[0077] During the process of sleeving a rubber plug or a screw cap on the capping member 33, first, the rubber plug or the screw cap is transported to one end of the slide rail 34 by the hoist 4. Guided by the slide rail 34, it slides from one end of the slide rail 34 to the other end. At the other end of the slide rail 34, when the drag cover plate 36 is in the first position, the rubber plug or the screw cap slides into the cover groove 38. When the drag cover plate 36 moves from the first position to the second position, the drag cover plate 36 closes the other end outlet of the slide rail 34. At the same time, the rubber plug or the screw cap is located below the capping member 33. The capping member 33 is pressed down by the first lifting frame 32. If it is a rubber plug, the capping member 33 will squeeze into the rubber plug, and the rubber plug is sleeved on one end of the capping member 33. If it is a screw cap, the capping member 33 will be sleeved outside the screw cap, and the screw cap is fixed on one end of the capping member 33 by friction. After that, the drag cover plate 36 moves from the second position to the first position, that is, the drag cover plate 36 moves away from below the capping member 33, completing the process of installing the rubber plug or the screw cap on the capping member 33.

[0078] Furthermore, in this embodiment, the capping structure 3 further includes a first screw 39, a positioning frame 310, and a first motor 311. The positioning frame 310 is connected to the first fixing frame 31. The first motor 311 is disposed on the positioning frame 310. The output end of the first motor 311 is connected to the first screw 39. The first screw 39 is rotatably connected to the first fixing frame 31, and the first screw 39 cooperates with the first lifting frame 32.

[0079] During the process of controlling the capping member 33 and the first lifting frame 32, the positioning frame 310 fixes the positions of the first motor 311 and the first screw 39. The first motor 311 drives the first screw 39 to rotate. Since the first lifting frame 32 moves up and down on the first fixing frame 31 and cannot rotate, the first screw 39 drives the first lifting frame 32 to lift, thereby realizing the first motor 311 driving the first lifting frame 32 and the capping member 33 to lift.

[0080] Specifically, in this embodiment, it further includes a hoist 4, and the hoist 4 includes a frame 41, a transfer member 42, a storage basket 43, a lifting belt 44, a cross plate 45, and an intercepting plate 47;

[0081] The frame 41 is arranged on one side of the workbench 1. A transfer area for storing caps is provided on the frame 41. The transfer member 42 is connected to the frame 41. One end of the transfer member 42 communicates with the slide rail 34, and the other end of the transfer member 42 communicates with the transfer area. The storage basket 43 is connected to the frame 41. A to-be-lifted area for placing caps exists in the storage basket 43. The lifting belt 44 slides inside the frame 41. The cross plate 45 is connected to the lifting belt 44. The length direction of the cross plate 45 is perpendicular to the moving direction of the lifting belt 44. The cross plate 45 and the lifting belt 44 enclose a lifting area for picking up caps. The lifting area can pass through the to-be-lifted area and the transfer area. The hoist 4 further includes a front plate 46. The front plate 46 is connected to the frame 41. The lifting belt 44 rotates inside the frame 41. The front plate 46 is arranged between the to-be-lifted area and the transfer area. The opening at one end of the transfer member 42 connected to the transfer area is only for the side placement of caps to pass through. The intercepting plate 47 is connected to the frame 41. The intercepting plate 47 is located in the transfer area;

[0082] In this application, the cross plate 45 moves driven by the lifting belt 44. When the cross plate 45 passes through the to-be-lifted area, the cross plate 45 and the lifting belt 44 enclose an L shape, so that the rubber stopper or the screw cap leans on the cross plate 45 and the lifting belt 44. When the lifting belt 44 gradually tends to be vertical, the rubber stopper or the screw cap falls onto the cross plate 45. When the lifting belt 44 enters the transfer area, the movement path of the lifting belt 44 will gradually tend to be horizontal. In this process, the rubber stopper or the screw cap will be scraped off from between the cross plate 45 and the lifting belt 44 by the intercepting plate 47, so that the rubber stopper or the screw cap falls into the transfer area, completing the lifting of the rubber stopper or the screw cap. After that, the cross plate 45 continues to operate driven by the lifting belt 44 until the cross plate 45 rotates one week and returns to the to-be-lifted area again. In this operation mode, multiple cross plates 45 are installed on the lifting belt 44, which can realize more efficient lifting of the rubber stopper or the screw cap.

[0083] It should be noted that during the process of filling the reagent bottle with acid solution, the acidic liquid will volatilize after contacting the air, thus generating acidic gas. However, in the prior art, there is a lack of a device for recovering the acidic gas, which will cause the acidic gas to disperse in the workshop. The staff in the workshop will absorb the acidic gas, thus causing harm to the body. Therefore, this application adds an exhaust gas collection device in the link of filling the reagent bottle with acid solution. The exhaust gas collection device is located above the acid solution filling area;

[0084] The exhaust gas collection device includes a negative pressure pipe 14, a first installation pipe 16, a storage tank 18 and a second installation pipe 19. The negative pressure pipe 14 is vertically arranged, and a plurality of the storage tanks 18 are arranged side by side on one side of the negative pressure pipe 14. A negative pressure component is arranged in the negative pressure pipe 14. The first installation pipe 16 is horizontally arranged and located below the negative pressure pipe 14.

A plurality of air inlet components are arranged at intervals at the lower end of the first installation pipe 16. The second installation pipe 19 is located above the first installation pipe 16. The second installation pipe 19 is connected and communicated with the air outlet end of the storage tank 18 through a plurality of connection components. The storage tank 18 is located at the upper end of the filling production line and is installed through an installation bracket 35.

[0085] In the present invention, when the device needs to be used, the negative pressure pipe 14 can be made negative pressure through the negative pressure component, and the negative pressure pipe 14 is connected to the first installation pipe 16 and the second installation pipe 19, so that the first installation pipe 16 and the second installation pipe 19 can be made negative pressure. Thus, the acidic gas generated by the acid liquid volatilization at the storage tank 18 and the filling production line can be absorbed through the connection component and the air inlet component respectively, and enter the negative pressure pipe 14 and be discharged under the action of the negative pressure component. The device can effectively recover the acidic gas generated during filling production and the acidic gas in the storage tank 18, thereby effectively reducing the harm caused by the dispersion of acidic gas to the bodies of the staff.

[0086] In an optional embodiment, the air inlet component includes an absorption pipe 17.

[0088] In an alternative embodiment, a valve 22 and a connecting pipe 23 are further included. One end of the connecting pipe 23 is connected to and communicates with the gas outlet end of the storage tank 18. The other end of the connecting pipe 23 is connected to the valve 22. The valve 22 is connected to the end of the connecting pipe 21 away from the tee joint 20. Through the valve 22 and the connecting pipe 23, the connection between the storage tank 18 and the connecting pipe 21 can be effectively completed, and the opening and closing between the storage tank 18 and the connecting pipe 21 can be effectively controlled through the valve 22.

[0089] In an alternative embodiment, the valve 22 is a solenoid valve, and the solenoid valve can be controlled through a relay, so that there is no need for staff to directly operate the valve 22 manually, thereby effectively reducing the working intensity of the staff.

[0090] In an alternative embodiment, an extension pipe 24 arranged in a Z shape is further included. A third air inlet is provided at the bottom end of the first installation pipe 16. The extension pipe 24 is fixedly arranged in the third air inlet and is connected to and communicates with the first installation pipe 16.

External threads are provided on the outer peripheral surface of the end of the extension pipe 24 that communicates with the first installation pipe 16. A nut is threadedly arranged on the external threads, and the nut can be rotated to abut against the first installation pipe 16. The extension pipe 24 is rotatably arranged, so that the position of the bottom end of the extension pipe 24 can be adjusted as needed, thereby effectively recovering the acidic gas in the required area. And by rotating the nut to abut against the first installation pipe 16, the rotation position of the extension pipe 24 can be effectively fixed, thereby improving the stability of the device.

[0092] In an alternative embodiment, the negative pressure assembly includes a negative pressure pump 25. The negative pressure pump 25 is located in the negative pressure pipe 14 and is connected to its inner wall. Through the negative pressure pump 25, negative pressure can be created, so that negative pressure is generated in the first installation pipe 16 and the second installation pipe 19, thereby effectively recovering the acidic gas.
