[0044] In the production process of the oxygen generator, one of the processes is to fill the molecular sieve into the adsorption cylinder. In the related art, when the molecular sieve is filled into the adsorption cylinder, it is usually completed by manual operation, and multiple people are required to cooperate. The filling process can only be filled into the adsorption cylinder one by one, and when multiple adsorption cylinders (up to more than ten adsorption cylinders) are filled into a single machine, there are disadvantages of long operation time, low efficiency, and high labor intensity.

[0045] Therefore, the present application provides a molecular sieve feeding platform which can effectively improve the above problems.

[0046] For example, as shown in FIGS. Figure 1 and Figure 2 The molecular sieve feeding platform of one embodiment of the present application comprises a rack 100, a plurality of storage hoppers 200, a plurality of communication parts 400, and a plurality of filling parts 500.

[0047] A plurality of storage hoppers 200 are arranged on the top of the frame 100, the storage hopper 200 is provided with a feeding port 201 and a discharging port 202, the feeding port 201 is located at the top of the storage hopper 200, the discharging port 202 is located at the bottom of the storage hopper 200, the storage hopper 200 is provided with a first opening and closing mechanism 300 at the discharging port 202, the first opening and closing mechanism 300 is used to open or close the discharging port 202, it is conceivable that the first opening and closing mechanism 300 can adopt various forms of valves, as long as it can open or close the discharging port 202. Obviously, before filling the molecular sieve into the adsorption cylinder 700, the molecular sieve can be input into the storage hopper 200 through the feeding port 201.

[0048] The communication part 400 corresponds to the discharging port 202 one by one, the communication part 400 is connected to the corresponding discharging port 202, the communication part 400 is a flexible structure, that is, the communication part 400 can be deformed arbitrarily, the inside of the communication part 400 defines a connecting channel penetrating along the length direction of itself, the connecting channel is communicated with the discharging port 202.

[0049] The filling part 500 corresponds to the communication part 400 one by one, the filling part 500 is connected to the end of the corresponding communication part 400 away from the discharging port 202, the inside of the filling part 500 defines a filling channel penetrating through the filling part 500, the filling channel is communicated with the connecting channel, obviously, the end of the filling part 500 away from the communication part 400 is used to dock the adsorption cylinder 700; it is conceivable that the filling part 500 is a rigid structure, so as to dock the adsorption cylinder 700.

[0050] The molecular sieve feeding platform arranged by the above structure can place a plurality of adsorption cylinders 700 of a single multi-tower host machine below the filling part 500 when filling the molecular sieve, then make the filling part 500 dock the adsorption cylinder 700, and open the first opening and closing mechanism 300, so as to fill the molecular sieve in the storage hopper 200 into the adsorption cylinder 700, realize the filling of a plurality of adsorption cylinders 700 at one time, the filling efficiency is high, and one person can complete the operation; since the communication part 400 is a flexible structure, the filling part 500 has a certain space to move relative to the discharging port 202, which can facilitate the docking of the filling part 500 and the adsorption cylinder 700, save operation time; in addition, for a single multi-tower host machine, since a plurality of adsorption cylinders 700 are connected as a whole, after filling part of the adsorption cylinders 700, the overall mass will be heavier and inconvenient to move, at this time, since the communication part 400 is a flexible structure, the remaining unfilled adsorption cylinders 700 can be docked by moving the filling part 500, which can improve the filling efficiency and reduce the labor intensity.

[0051] Reference Figure 1 and Figure 2As shown in some embodiments of the utility model, the connecting part 400 is set as a soft cloth bag, and the soft cloth bag has the advantages of low cost and large activity space of the filling part 500. Of course, it is conceivable that in some other embodiments, the connecting part 400 can also be set as a hose structure.

[0052] It can be understood that in some embodiments of the utility model, the filling part 500 can be provided with a funnel shape, which is large at the top and small at the bottom, and is hollow inside. Of course, in some other embodiments, the filling part 500 can also be set as the structure form in the "molecular sieve filling device of oxygen generator" disclosed in the publication number "CN212174455U" to realize the storm snow type filling effect, so that the molecular sieve is uniformly filled and tightly packed.

[0053] Referring to Figure 1 and Figure 2 As shown in some embodiments of the utility model, the molecular sieve feeding platform further comprises a mobile vehicle 600, and the mobile vehicle 600 is located below the filling part 500. The mobile vehicle 600 is provided with a mounting position for mounting and fixing the adsorption cylinder 700. Obviously, the mobile vehicle 600 and the adsorption cylinder 700 can be connected in the form of bolt connection. In this embodiment, the mobile vehicle 600 can be used to transfer the adsorption cylinder 700, thereby improving the efficiency and reducing the labor intensity.

[0054] In addition, it should be noted that for a single multi-tower host, if the number of adsorption cylinders 700 is relatively large, the mobile range of the filling part 500 is not enough to cover all the adsorption cylinders 700 when the mobile vehicle 600 is stationary. The mobile vehicle 600 can be moved to enable the filling part 500 to be connected with the adsorption cylinder 700. Of course, when the mobile vehicle 600 is stationary and the mobile range of the filling part 500 is enough to cover all the adsorption cylinders 700, the filling operation can be completed by adjusting the filling part 500.

[0055] Referring to Figure 1 As shown in some embodiments of the utility model, the plurality of storage hoppers 200 are arranged along the length direction of the rack 100. It can be understood that for a single multi-tower host, the plurality of adsorption cylinders 700 are usually arranged side by side, for example Figure 1 and Figure 2 As shown, the plurality of adsorption cylinders 700 are arranged side by side as two groups, so that in this embodiment, the plurality of storage hoppers 200 are arranged along the length direction of the rack 100. When the mobile vehicle 600 carrying the adsorption cylinder 700 is transferred to below the filling part 500 during filling, the arrangement direction of the adsorption cylinders 700 in the same group can be kept consistent with the length direction of the rack 100, so that the filling part 500 can be conveniently filled in each adsorption cylinder 700 in turn along the arrangement direction of the adsorption cylinders 700 in the same group.

[0056] In addition, it can be understood that when only one specification of single multi-tower main machine of the plurality of adsorption cylinders 700 needs to be filled, that is, the number, size and spacing between adjacent adsorption cylinders 700 are fixed, in order to facilitate the active adjustment of the filling part 500, a linkage rod can be arranged between all the filling parts 500 to facilitate synchronous movement to adjust all the filling parts 500, save operation time, and the linkage rod can be bolted with each filling part 500 to facilitate disassembly.

[0057] Referring to Figure 1 As shown in the drawings, in some embodiments of the present application, the storage hopper 200 is provided with a dust removal port 203, and the outside of the dust removal port 203 is sleeved with a dust removal bag 204, and a plurality of filter holes are arranged on the dust removal bag 204. By arranging the dust removal bag 204, the dust generated during the feeding process of the storage hopper 200 and the filling process of the storage hopper 200 to the adsorption cylinder 700 is removed, and the influence on the operation is reduced.

[0058] Referring to Figure 1 As shown in the drawings, in some embodiments of the present application, a plurality of storage hoppers 200 are arranged in an integrated structure to facilitate processing and manufacturing, the tops of two adjacent storage hoppers 200 are connected, and the dust removal port 203 is arranged on one of the storage hoppers 200. In this way, the plurality of storage hoppers 200 can share the same dust removal bag 204.

[0059] Referring to Figure 1 and Figure 3 As shown in the drawings, in some embodiments of the present application, the molecular sieve feeding platform further comprises a hopper and a feeding device 800. The hopper (not shown in the drawings) is arranged on the ground and is used for storing molecular sieves; the feeding device 800 is arranged between the hopper and the storage hopper 200, and is used for conveying the molecular sieves in the hopper to the storage hopper 200; it can be understood that in order to facilitate filling of the molecular sieves into the adsorption cylinder 700, the storage hopper 200 needs to be arranged at a higher position, and in order to facilitate feeding, the feeding device 800 is arranged in the embodiment to facilitate conveying of the molecular sieves stored in the hopper to the storage hopper 200.

[0060] It is conceivable that the feeding device 800 can adopt various forms, for example, a screw conveyor or a pneumatic feeding form.

[0061] In some embodiments of the present application, the feeding device 800 is a negative pressure vacuum feeding structure, which utilizes negative pressure vacuum for feeding.

[0062] Specifically, referring to Figure 3As shown, the feeding device 800 includes a suction pipe 810 and a plurality of parallelly arranged branch pipes 820. The feeding end of the suction pipe 810 is provided with a feeder 840 for placing into a barrel to suck molecular sieves. The feeder 840 can adopt the structure form in the "vacuum conveyor" disclosed in the publication No. "CN205397513U", which is connected with a gas conveying pipeline to input compressed air to generate negative pressure, and the gas conveying pipeline is provided with a gas valve switch 850. The branch pipe 820 corresponds to the feeding port 201 one by one, one end of the branch pipe 820 is connected to the suction pipe 810, and the other end is connected to the feeding port 201. Each branch pipe 820 is provided with a second opening and closing mechanism 830 for controlling the on-off of the branch pipe 820. It is conceivable that the second opening and closing mechanism 830 can adopt various forms of valves, as long as it can control the on-off of the branch pipe 820, for example, a ball valve.

[0063] During feeding, only the second opening and closing mechanism 830 on one of the branch pipes 820 is opened each time to ensure the gas pressure and the height of the conveying material. The specific operation is as follows: first, the second opening and closing mechanism 830 of the branch pipe 820 corresponding to one of the storage hoppers 200 is opened, then the gas valve switch 850 is opened to start the feeder 840, and then the molecular sieves can be conveyed into the corresponding storage hopper 200. After the feeding of one storage hopper 200 is completed, the feeding of the next storage hopper 200 is performed. Before switching the storage hopper 200, the gas valve switch 850 is closed to stop the feeder 840 from sucking, the second opening and closing mechanism 830 opened before is closed, then the second opening and closing mechanism 830 corresponding to the next storage hopper 200 is opened, the gas valve switch 850 is opened again to suck the material for the feeding of the next storage hopper 200, and so on until the feeding of all the storage hoppers 200 is completed. Finally, the gas valve switch 850 is closed to stop the feeder 840 from working, and all the second opening and closing mechanisms 830 are closed.

[0064] Referring to Figure 1 As shown, in some embodiments of the present application, the filling part 500 is provided with a third opening and closing mechanism 510, which is located at one end of the filling part 500 away from the communication part 400 and is used for opening or closing the filling channel. It can be understood that when the filling part 500 switches the adsorption cylinder 700 for filling, there is still residual material in the filling part 500. Therefore, the third opening and closing mechanism 510 is arranged in the present embodiment, which can close the filling channel through the third opening and closing mechanism 510 when the filling part 500 switches the position, so as to prevent material leakage.

[0065] It is conceivable that the third opening and closing mechanism 510 can adopt various forms of valves, as long as it can open or close the filling channel.

[0066] The operation method of the molecular sieve feeding platform in one embodiment of the present application is as follows:

[0067] Step one, before filling, first close the first opening and closing mechanism 300 to close the discharge port 202, and then transport the molecular sieve in the material bucket to each storage hopper 200 through the feeding device 800, so that each storage hopper 200 has sufficient molecular sieve, after feeding, stop the feeding device 800.

[0068] Step two, use the moving vehicle 600 to transfer the plurality of adsorption cylinders 700 of the single multi-tower main machine to the lower side of the filling part 500, then open the first opening and closing mechanism 300 and the third opening and closing mechanism 510 after the filling part 500 is docked, and the molecular sieve in the storage hopper 200 is filled into the adsorption cylinder 700.

[0069] Step three, after the plurality of filling parts 500 complete a filling operation, first close the third opening and closing mechanism 510, and then transfer the filling part 500 to the adsorption cylinder 700 which has not been filled for filling, and repeat step three until the filling of all adsorption cylinders 700 is completed.

[0070] Step four, after all the adsorption cylinders 700 are filled, transfer the moving vehicle 600 to the assembly area for assembly, so as to reduce the time of exposing the molecular sieve to the air.

[0071] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in the present specification.

[0072] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of those skilled in the art without departing from the purpose of the present application.
