Description

Technical Field

[0001] This utility model relates to the field of flue gas capture and treatment technology, and specifically to a flue gas capture and treatment system. Background Technology

[0002] With the deepening of research on smoking and health, people are paying increasing attention to how to efficiently detect and collect cigarette smoke. During combustion, cigarettes produce a large amount of mainstream and sidestream smoke, containing many substances such as tar, nicotine, and carbon monoxide, which not only harm smokers but also cause air pollution. Currently, smoking machines are commonly used in the tobacco industry for detecting mainstream smoke. Rotary smoking machines are primarily used to draw cigarettes, and the content of tar, nicotine, and carbon monoxide in cigarette products is determined by detecting the mainstream smoke. Throughout the entire smoking process of the rotary smoking machine, the smoke collector is a crucial module for capturing total particulate matter from cigarettes. It is a device that collects cigarette sample smoke according to the requirements for determining smoke composition.

[0003] Currently, the operation of laboratory flue gas traps in the process of entering and exiting the fume extraction machine suffers from significant efficiency bottlenecks. Firstly, the entire operation is fragmented and independent, with a lack of effective coordination between each step, resulting in a cumbersome and time-consuming process. Secondly, after the flue gas traps have finished collecting data, they need to be sealed and stored. Currently, the sealing process relies primarily on manual operation to handle the ten flue gas traps that operate sequentially on the fume extraction machine. This operational efficiency is mismatched with the equipment's capacity, leading to wasted manpower and time. These problems collectively reflect the systemic deficiencies in the current flue gas trap operation process. Utility Model Content

[0007] This application integrates the flue gas collector loading / unloading device, sealing device, smoke extraction machine, and weighing device around a robotic arm. The robotic arm can grip the flue gas collector and remove it from the loading / unloading device, then sequentially enter the weighing device, smoke extraction machine, sealing device, weighing device, and flue gas collector loading / unloading device. This sequentially realizes the weighing of the flue gas collector, the collection of flue gas in the smoke extraction machine, sealing after completion, weighing and comparing again, and finally loading and collecting, completing the entire flue gas collector processing system. The integrated design saves space, and the coordinated and automated operation of each process improves the work efficiency between the various processes of the flue gas collector entering and leaving the smoke extraction machine, shortens the weight comparison time before and after sealing the flue gas collector, and improves the accuracy of flue gas collection and detection.

[0010] As a further embodiment of this utility model: the sealing device includes a base plate and a cap plate, a linear cylinder and a flue gas collector mounting block located above the base plate. The output end of the linear cylinder is connected to the flue gas collector mounting block, and the cap plate is located on the outside of the flue gas collector mounting block.

[0011] A drive mechanism is provided on one side of the cap plate, and a photoelectric positioning mechanism is provided on the other side.

[0012] As a further embodiment of this utility model: the cap plate includes two sets of symmetrically arranged turntables, the two sets of turntables are connected by a central axis, and several cap grooves are evenly distributed on the circumference of the two sets of turntables, and caps are installed in the cap grooves; the center of the two sets of turntables is connected to the support through a bearing, and the bottom of the support is installed on the base plate.

[0013] As a further embodiment of this utility model: a bracket is provided on the base plate and on the outside of the turntable, and a pushing block is provided on the top of the bracket facing the cap groove, the position of the pushing block corresponding to the position of the cap groove.

[0014] As a further embodiment of this utility model: the photoelectric positioning mechanism includes a positioning disc mounted on the central axis of another turntable. The positioning disc has several sets of slots at equal intervals corresponding to the cap slot. A photoelectric switch is provided on the outer side of the positioning disc. The photoelectric switch is connected to the corresponding support through a switch base.

[0015] As a further embodiment of this invention, the number of slots is the same as the number of cap slots on a single turntable.

[0016] As a further embodiment of this utility model: the driving mechanism includes a stepper motor located at the bottom of the base plate, the output end of the stepper motor is connected to a lower synchronous pulley, and the central shaft of one of the turntables is connected to an upper synchronous pulley, wherein the upper synchronous pulley and the lower synchronous pulley are connected by a synchronous belt drive.

[0017] As a further embodiment of this utility model: the weighing device includes a housing and a weighing unit installed inside the housing.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, this application integrates the flue gas collector loading and unloading device, sealing device, smoke extraction machine, and weighing device around a robotic arm. The robotic arm can grip the flue gas collector and remove it from the loading and unloading device, then sequentially enter the weighing device, smoke extraction machine, sealing device, weighing device, and flue gas collector loading and unloading device.

The integrated design saves space, and the automated operation improves work efficiency, shortens the weight comparison time before and after sealing the flue gas collector, and improves the accuracy of flue gas collection and detection.

[0020] Secondly, the sealing device of this application is equipped with two sets of symmetrical turntables, and several caps are installed on the turntables. When the linear cylinder pushes the flue gas collector between the two sets of turntables, the caps can be aligned with the flue gas collector by rotating the turntables and then moved onto the flue gas collector by using the push block. With the above configuration, multiple flue gas collectors can be sealed continuously in a fast manner, improving sealing efficiency, and the disc design saves space.

[0021] Finally, a positioning disc is set on one side of the turntable, and a slot corresponding to the cap is set on the positioning disc. The photoelectric switch is located on the outside of the positioning disc. When the positioning disc rotates to the point where the slot corresponds exactly to the photoelectric switch, the cap rotates to the point where it corresponds to the center of the flue gas collector. The photoelectric switch is used to accurately determine the rotation position of the cap to ensure that it can move accurately onto the flue gas collector. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Reference Figure 1 and Figure 2A flue gas collector collection and treatment system is used for the initial clamping and weighing of the flue gas collector before it enters the smoke extraction machine, and for the subsequent clamping, weighing, and sealing operations. It includes a workbench 1 and a flue gas collector loading component 2, a flue gas collector unloading component 3, a sealing device 4, and a weighing device 5 mounted on the workbench 1. A robotic arm mounting slot 6 is provided on the workbench 1 for mounting a robotic arm. The flue gas collector loading component 2, the flue gas collector unloading component 3, the sealing device 4, and the weighing device 5 are located around the robotic arm for easy operation.

[0037] Reference Figure 1 The flue gas collector feeding component 2 is used for unloading (the material is stored in the flue gas collector 7). The flue gas collector feeding component 2 includes a base and three limiting baffles 22 installed on the top of the base. Limiting rings 23 are fixed between the three limiting baffles 22. A pusher component 21 is provided on the top of the base and directly below the limiting rings 23. Several flue gas collectors 7 are supported above the pusher component 21 by a clamp. The clamp is located inside the limiting baffles 22 and the pusher component 21 is positioned above the limiting baffles 22. Above, the inner diameter of the limiting ring 23 is larger than the outer diameter of the flue gas collector 7, so it does not affect the up and down movement of the flue gas collector 7; generally, ten flue gas collectors 7 are placed in the feeding part 2 of the flue gas collector, and ten are placed as a group. By moving the pushing part 21 upward, the flue gas collector 7 located at the bottom can be pushed upward and moved downward with the pushing part 21, so that the flue gas collector 7 at the bottom is moved onto the pushing part 21, and then it can be picked up by the robot arm.

[0038] Reference Figure 1 The flue gas collector unloading component 3 is located on one side of the flue gas collector loading component 2 and is used for loading (the material is the flue gas collector 7). The flue gas collector unloading component 3 has the same overall frame as the flue gas collector loading component 2. It can also hold ten of them, and ten are a group. The difference is that the robot needs to put the flue gas collector 7 after the flue gas is captured into the pusher at the bottom of the flue gas collector unloading component 3. Then the pusher at the bottom moves up to move the flue gas collector 7 to the inside of the clamping component of the flue gas collector unloading component 3. The clamping component is located inside the limiting baffle and above the pusher.

[0039] Reference Figure 4 and Figure 5 The sealing device 4 includes a base plate 41 and a linear cylinder 42 and a flue gas collector mounting block 43 mounted on the base plate 41. The flue gas collector mounting block 43 is mounted on the output end of the linear cylinder 42, and the linear cylinder 42 can drive the flue gas collector mounting block 43 to move. The linear cylinder 42 is detachably mounted on the base plate 41 by bolts or pins.

[0040] Furthermore, two sets of symmetrically arranged circular turntables 49 are installed on the top of the base plate 41 and in front of the flue gas collector mounting block 43. The central axes of the two sets of turntables 49 are connected, enabling synchronous rotation. Several cap slots are evenly distributed around the circumference of each set of turntables 49, and caps 48 are installed in the cap slots. It should be noted that the number of cap slots in this application is the same as the number of flue gas collectors that can be stored in the flue gas collector unloading part 3 and the flue gas collector loading part 2, which is ten in total. One process realizes the loading, flue gas collection, capping and unloading of ten consecutive flue gas collectors.

[0041] Furthermore, refer to Figure 4 and Figure 5 Both sets of turntables 49 are connected to the support 410 via bearings on the outer side of their central shafts. The bottom of the support 410 is detachably mounted on the base plate 41 via bolts or pins. The central shaft of one of the turntables 49 passes through the corresponding support 410 and is connected to an upper synchronous pulley 411. A stepper motor 414 is mounted on the bottom of the base plate 41, and the output end of the stepper motor 414 is connected to a lower synchronous pulley 413. The upper synchronous pulley 411 and the lower synchronous pulley 413 are connected by a synchronous belt 412. Therefore, by controlling the stepper motor 414 to work, the upper synchronous pulley 411 and the lower synchronous pulley 413 can be driven to rotate synchronously, thereby driving the two coaxial turntables 49 to rotate synchronously, thus adjusting the position of the cap 48.

[0042] A bracket 44 is provided on the base plate 41 and on the outer side of the front end of the flue gas collector mounting block 43 near the turntables 49 on both sides. A push block 46 is provided on the top of the bracket 44 facing the cap groove, and a push cylinder 45 is provided on the top of the bracket 44 facing away from the cap groove. The push cylinder 45 is connected to the push block 46. The push cylinder 45 can drive the push block 46 to move toward the position of the cap groove and push the cap in the cap groove to lock onto the flue gas collector 7, thereby achieving a seal on the flue gas collector 7. The longitudinal and lateral positions of the push block 46 correspond to the positions of the cap grooves. By rotating the turntable 49, the cap grooves on it can be driven to align with the push block 46 in sequence, so that all the caps 48 can be moved by the push block 46.

[0043] Reference Figure 5A positioning disc 415 is mounted on a support 410 of another turntable 49. The positioning disc 415 is connected to the central axis of the turntable 49. The size of the positioning disc 415 is smaller than that of the turntable 49. Several sets of slots 416 corresponding to the cap slots are evenly spaced on the positioning disc 415. The number of slots 416 is the same as the number of cap slots on a single turntable 49. In this application, ten sets are provided. A photoelectric switch 417 is provided on the outside of the positioning disc 415. The photoelectric switch 417 is connected to the corresponding support 410 through a switch base 418. When the turntable 49 rotates, it can synchronously drive... The positioning disc 415 rotates. When the slot 416 on the positioning disc 415 moves to the position of the photoelectric switch 417, the caps 48 on the two turntables 49 are exactly located at the cap mounting positions on both sides of the flue gas collector 7. After the photoelectric switch 417 detects the position of the slot 416, it notifies the stepper motor 414 to stop rotating and perform the corresponding cap sealing. All subsequent cap positions are determined by the positioning between the photoelectric switch 417 and the slot 416. In order to ensure the accuracy of the cap rotation position, it is necessary to ensure that the angle between two adjacent slots 416 is the same as the angle between two adjacent cap slots.

[0044] Reference Figure 3 The weighing device 5 includes a housing 51, with a sliding door 52 on the side of the housing 51 facing the robot arm; a weighing unit 53 is installed inside the housing 51 for weighing the flue gas collector 7.

[0045] The specific operating principle of this application is as follows:

[0046] Before use, install the robotic arm on the robotic arm mounting slot 6, then put the flue gas collectors 7 into the flue gas collector loading part 2 in groups of ten, then push the bottom flue gas collector 7 up through the pusher 21 and put the bottom flue gas collector 7 into the pusher 21. Then the robotic arm picks up the flue gas collector 7 and puts it on the weighing device 5 for weighing before collecting the flue gas. After weighing, the weight is recorded and uploaded.

[0047] The robotic arm then continues to grip and move the flue gas collector 7 into the smoke extraction machine to collect flue gas. After the flue gas collection is completed, the robotic arm removes the flue gas collector 7 from the smoke extraction machine and puts it back into the weighing device 5 to weigh the flue gas after collection. The weight is recorded and uploaded after weighing. The content of particulate matter in the flue gas is then determined by comparing the weight before and after the collection.

[0048] After weighing is completed, the robotic arm picks up the flue gas collector 7 from the weighing device 5 and places it onto the flue gas collector mounting block 43 in the sealing device 4. Then, the linear cylinder 42 pushes the flue gas collector mounting block 43 to move between the two turntables 49. At this time, the cap openings on both sides of the flue gas collector 7 are exactly aligned with the cap slots on the turntables 49. Subsequently, the stepper motor 414 drives the two turntables 49 to rotate. When the slot 416 on the positioning disc 415 moves to the position of the photoelectric switch 417, the caps 48 on the two turntables 415 are exactly located at the cap mounting positions on both sides of the flue gas collector 7. After the photoelectric switch 417 detects the position of the slot 416, it notifies the stepper motor 414 to stop rotating and perform the corresponding cap sealing. All subsequent cap positions are determined by the positioning between the photoelectric switch 417 and the slot 416.

[0049] After the sealing is completed, the robotic arm picks up the flue gas collector 7 from the flue gas collector mounting block 43 and transfers it into the flue gas collector unloading part 3 for storage.

[0050] By analogy, the ten flue gas collectors 7 are sequentially subjected to the above-mentioned process of clamping, weighing, flue gas collection, weighing again, and storage.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
