Description

Technical Field

[0001] The present invention relates to the technical field of preparation and filling equipment, and particularly to a photocatalyst preparation and filling equipment. Background Technique

[0002] Photocatalyst, also known as a photocatalyst, is a general term for semiconductor materials with photocatalytic functions represented by nanoscale titanium dioxide. The representative photocatalyst material is titanium dioxide, which can generate strongly oxidizing substances (such as hydroxyl radicals, oxygen, etc.) under light irradiation and can be used to decompose organic compounds, some inorganic compounds, bacteria, and viruses. In daily life, photocatalysts can effectively degrade toxic and harmful gases in the air such as formaldehyde, efficiently purify the air; at the same time, they can effectively kill a variety of bacteria and decompose and detoxify the toxins released by bacteria or fungi.

[0003] In the prior art, the photocatalyst used for removing formaldehyde usually needs to be produced and prepared into a mixed liquid state for spraying and use with an aerosol can. Therefore, in the production and packaging process of photocatalysts, not only is it necessary to use a gas filling device to fill compressed gas into the tank bottle, but also a liquid filling device is required to fill the photocatalyst suspension into the tank bottle.

[0004] For example, the Chinese utility model patent (authorization announcement number: CN 205275175 U, authorization announcement date: June 1, 2016) discloses a fully automatic photocatalyst liquid quantitative filling equipment. This solution can remove the air in the dispensing container by a negative pressure air extraction device before filling, and can aspirate the filling head after filling to prevent solution dripping and drawing, ensuring good overall sealing effect during the filling process, more uniform filling, and automatic and efficient filling.

[0005] However, this solution uses a linear filling equipment for filling operations. During specific operation, the container bottles need to pass one by one under the filling head in sequence. When the frontmost container bottle is under the filling head, the conveying mechanism needs to stop running. After the filling head is docked with the container bottle and the photocatalyst suspension is filled into the container bottle, the conveying mechanism can continue to work and push the next container bottle to directly below the filling head. Obviously, this processing and filling method has a relatively long waiting time, the number that can be filled per unit time is limited, and the overall preparation and filling work efficiency still needs to be improved.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. In the photocatalyst preparation and filling equipment of the present invention, the moving route of the gas filling and liquid filling operations of the tank bottles is in an "S" shape. During the gas filling or liquid filling operation of the previous tank bottle, the remaining tank bottles can be positioned, gas filled or liquid filled in sequence.

On the one hand, the bottom disc in the present invention can play a supporting role, used to support and fix each filling component, and can also drive each filling component to rotate with the corresponding tank bottle, so that each bottom limiting part passes through the feeding position and the discharging position in sequence, realizing continuous gas filling and liquid filling operations; on the other hand, the bottom disc can also play a clamping role. Cooperating with the filling component, it can clamp and position the tank bottle, enabling the tank bottle to rotate stably and simultaneously complete the gas filling or liquid filling operation;

[0032] 3. The structural design of the intermediate bottle-pushing mechanism and the discharging bottle-pushing mechanism in the present invention is reasonable, and can cooperate with components such as the bottom guiding side plate and the guiding rod assembly to complete the position transfer of the tank bottle. The overall structure is simple and the use and operation are convenient;

Detailed implementation manners

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Please refer to Figures 1 to 19The present invention provides a technical solution: a photocatalyst preparation and filling device, comprising an equipment chassis 100, a work platform 101 on the equipment chassis 100, and a disc-type gas filling device 200 and a disc-type liquid filling device 300. The disc-type gas filling device 200 and the disc-type liquid filling device 300 each comprise a bottom disc 1 and a plurality of filling assemblies distributed and mounted on the bottom disc 1. The bottom disc 1 is rotatably mounted on the work platform 101. A plurality of bottom stoppers 12 for limiting the position of bottles 700 are distributed and mounted on the outer ring of the upper end surface of the bottom disc 1. Each filling assembly corresponds to a corresponding bottom stopper 12. To prevent bottles 700 from being directly pushed to other positions on the surface of the bottom disc 1, an outer edge rib 11 is further provided on the outer edge of the bottom disc 1. In this embodiment, the bottom stopper 12 can be a U-shaped component with an outward opening, and the number of filling assemblies on each bottom disc 1 can be specifically set to four.

[0058] The disc-type filling device 300 also includes a quantitative filling assembly for introducing a quantitative amount of photocatalyst suspension into the filling assembly of the disc-type filling device 300. Furthermore, a bottom rotary cylinder 2 is fixedly mounted on the base plate 104 within the equipment chassis 100, which interfaces with the disc-type filling device 200 and the disc-type filling device 300, respectively. A flange bracket 21 is fixedly mounted on the driving end of the bottom rotary cylinder 2, the upper end of which is fixedly connected to the lower end surface of the corresponding bottom disc 1. The bottom rotary cylinder 2 drives the bottom disc 1 to rotate. In this embodiment, the bottom rotary cylinder 2 can be specifically a four-station 360° rotary cylinder, rotating 90° each time.

[0059] The intermediate bottle-prying mechanism 400 is used to push the bottles 700 in the bottom limiter 12 at the discharge station of the disc-type gas filling device 200 into the bottom limiter 12 at the feed station of the disc-type liquid filling device 300; the discharge bottle-prying mechanism 500 is used to push the bottles 700 in the bottom limiter 12 at the discharge station of the disc-type liquid filling device 300 out.

[0060] Among them, the intermediate can-pushing mechanism 400 and the discharging can-pushing mechanism 500 both include a deflection cylinder 401 and a toggle plate 402. The deflection cylinder 401 is fixed at the corresponding position at the lower end of the working platform 101 through the cylinder seat plate. The driving rod of the deflection cylinder 401 passes through the working platform 101 and is fixedly installed with a toggle plate 402 for pushing the can bottle 700.

[0061] At the corresponding position of the working platform 101, there are also extended a feeding seat plate 102 and a discharging seat plate 103. A pair of symmetrically arranged guide rod assemblies 600 are installed on both the feeding seat plate 102 and the discharging seat plate 103. Each guide rod assembly 600 includes a guide cross bar 603 and a plurality of guide supports 601. The guide supports 601 are fixedly installed on the side edges of the feeding seat plate 102 or the discharging seat plate 103. A support rod 602 is installed on the guide support 601. The guide cross bar 603 is fixedly connected to each support rod 602 by bolts. The structural design of the guide rod assembly 600 is simple and reasonable, and can effectively guide the sequential movement of the tank bottles 700. In specific applications, a pair of symmetrically arranged bottom guide side plates 105 can also be installed at the feeding station and the discharging station of the working platform 101. Similarly, at the docking position between the disk-type liquid filling device 300 and the disk-type gas filling device 200, a pair of symmetrically arranged bottom guide side plates 105 can also be fixedly installed on the working platform 101.

[0062] The working principle of the present invention is: In specific use, the outlet end of an external bottle arranging device can be docked with the feeding seat plate 102, and the external bottle arranging device sequentially pushes the tank bottles 700 onto the feeding seat plate 102;

[0063] Under the guidance of the guide rod assembly 600, the first tank bottle 700 is pushed into the bottom limiting member 12 corresponding to the feeding end of the upper end face of the bottom disk 1 in the disk-type gas filling device 200. Then, the filling assembly of the disk-type gas filling device 200 is docked with the valve nozzle 701 of the tank bottle 700, and compressed gas is filled into the tank bottle 700; At the same time, the bottom rotating cylinder 2 drives the bottom disk 1 to rotate 90°, so that the next bottom limiting member 12 rotates to the feeding end, and the second tank bottle 700 can be pushed into this bottom limiting member 12. Then, the filling assembly of the disk-type gas filling device 200 is docked with the valve nozzle 701 of the tank bottle 700...;

[0064] And so on, until the fourth tank bottle 700 is pushed into the bottom limiting member 12 at the feeding end. At this time, the gas filling operation of the first tank bottle 700 is completed and it is rotated to the discharging end of the disk-type gas filling device 200. Then, the deflecting cylinder 401 of the intermediate tank pushing mechanism 400 acts, driving the deflecting plate 402 to rotate. The deflecting plate 402 can then push the first tank bottle 700 from the bottom limiting member 12 of the disk-type gas filling device 200 into the bottom limiting member 12 of the disk-type liquid filling device 300;

[0065] Then, the filling assembly of the disc-type liquid filling device 300 is docked with the valve nozzle 701 of the can bottle 700, and the quantitative filling assembly starts to work, filling the photocatalyst suspension into the can bottle 700 through the filling assembly. During the filling process, the bottom rotating cylinder 2 will also drive the bottom disc 1 of the disc-type liquid filling device 300 to rotate 90°, so that the next bottom limiting member 12 rotates to the feeding position. Then, the second can bottle 700 can enter the bottom limiting member 12 under the push of the middle can shifting mechanism 400. Then, the filling assembly of the disc-type liquid filling device 300 is docked with the valve nozzle 701 of the can bottle 700, and the corresponding quantitative filling assembly starts to work...; and so on. When the fourth can bottle 700 is pushed to the feeding position of the disc-type liquid filling device 300, at this time, the gas filling operation of the first can bottle 700 is completed and it is rotated to the discharging position of the disc-type gas filling device 200. The deflecting cylinder 401 of the discharging can shifting mechanism 500 acts, and by using the swinging shifting plate 402, the first can bottle 700 that has been filled can be pushed onto the discharging seat plate 103.

[0066] In the present invention, the movement routes of the gas filling and liquid filling operations of the can bottle 700 are in an "S" shape. During the gas filling or liquid filling operation of the previous can bottle 700, the remaining can bottles 700 can be sequentially positioned and gas filled or liquid filled. Compared with the linear filling equipment in the prior art, the photocatalyst preparation and filling equipment of the present invention does not need to wait for a long filling time, and the number that can be filled per unit time is effectively increased, greatly improving the working efficiency of photocatalyst preparation and filling.

[0067] In the present invention, on the one hand, the bottom disc 1 can play a supporting role, used to support and fix each filling assembly, and can also drive each filling assembly to rotate with the corresponding can bottle 700, so that each bottom limiting member 12 passes through the feeding position and the discharging position in sequence, realizing continuous gas filling and liquid filling operations; on the other hand, the bottom disc 1 can also play a clamping role. Cooperating with the filling assembly, it can clamp and position the can bottle 700, so that the can bottle 700 can rotate stably and at the same time can complete the gas filling or liquid filling operation.

[0068] In addition, the structural designs of the middle can shifting mechanism 400 and the discharging can shifting mechanism 500 are reasonable, and can cooperate with components such as the bottom guiding side plate 105 and the guiding rod assembly 600 to complete the position transfer of the can bottle 700. The overall structure is simple and the use and operation are convenient.

[0069] As a specific solution of the present invention, the filling assembly includes a filling bracket 3, a positioning cylinder 4, a filling cylinder 5 and a filling valve head assembly 6. The filling valve head assembly 6 is used to dock with the valve nozzle 701 of the can bottle 700. The bottom end of the filling bracket 3 is fixedly installed on the upper end surface of the bottom disc 1, the top end of the filling bracket 3 is fixedly installed with a top filling seat plate 31, and a filling sliding seat 41 is slidably installed on the outer wall of the filling bracket 3. The positioning cylinder 4 is fixedly installed on the top filling seat plate 31, and the telescopic end of the positioning cylinder 4 is docked with the lower filling sliding seat 41. The filling cylinder 5 is fixedly installed on the filling sliding seat 41, and the telescopic end of the filling cylinder 5 is docked with the lower filling valve head assembly 6. Each filling valve head assembly 6 is located directly above the corresponding bottom limiting member 12.

[0070] The working principle of the filling assembly is as follows: When the can bottle 700 is pushed into the bottom limiting member 12 of the bottom disc 1, the corresponding positioning cylinder 4 works to drive the filling sliding seat 41, the filling cylinder 5 and the filling valve head assembly 6 to descend, so that the filling valve head assembly 6 is positioned and docked with the valve nozzle 701 of the can bottle 700. Then, the filling cylinder 5 works to make the filling valve head assembly 6 press the valve nozzle 701 of the can bottle 700. Then, the filling valve head assembly 6 can fill compressed gas or photocatalyst suspension into the can bottle 700.

[0071] As a specific solution of the present invention, the filling valve head assembly 6 includes a top valve cylinder 62, a bottom valve cylinder 64 and an internal filling pipe 63. A valve head flange seat 61 is fixedly installed at the upper end of the top valve cylinder 62, and the valve head flange seat 61 is fixedly docked with the telescopic end of the filling cylinder 5.

[0072] An internal filling pipe 63 is fixedly installed inside the top valve cylinder 62. The inlet end of the internal filling pipe 63 passes through the side wall of the top valve cylinder 62 and is docked with a filling inlet nozzle joint 633.

[0073] The upper end of the bottom valve cylinder 64 is movably inserted and fitted into the circumferential inner wall of the top valve cylinder 62. A bottom valve cylinder convex ring 641 is integrally extended on the outer wall of the lower end of the bottom valve cylinder 64. A spring 68 is sleeved at the lower end of the top valve cylinder 62. The upper end of the spring 68 is in contact connection with the step ring on the outer wall of the top valve cylinder 62, and the lower end of the spring 68 is in contact connection with the bottom valve cylinder convex ring 641. A limiting and guiding cone seat 631 is fixedly sleeved at the lower end of the internal filling pipe 63. A filling nozzle 632 for docking with the valve nozzle 701 of the can bottle 700 is fixedly embedded in the center of the lower end surface of the limiting and guiding cone seat 631. The filling nozzle 632 is communicated with the internal filling pipe 63 through the central hole of the limiting and guiding cone seat 631. The upper end inside the bottom valve cylinder 64 also has a conical valve cylinder inner wall for cooperating with the limiting and guiding cone seat 631.

[0074] In the present invention, on the one hand, the internal perfusion tube 63 can play the role of guiding gas or liquid. On the other hand, the internal perfusion tube 63 cooperates with the limit guiding cone seat 631 to limit the pulling of the bottom valve cylinder 64, preventing the bottom valve cylinder 64 from completely disengaging from the top valve cylinder 62 under the elastic force of the spring 68. Additionally, when the bottom valve cylinder 64 descends and resets under the elastic force of the spring 68, the bottom valve cylinder 64 can push and press the limit guiding cone seat 631 by using the inner wall of the conical valve cylinder, thereby pulling the internal perfusion tube 63, which can play a certain role in correcting and shaping the internal perfusion tube 63 to ensure that the internal perfusion tube 63 remains vertical, so that the perfusion nozzle 632 can accurately dock with the valve nozzle 701 of the can bottle 700.

[0075] Wherein, a first annular clamp seat 65 is fixedly butted to the lower end surface of the bottom valve cylinder convex ring 641. A second annular clamp seat 66 is fixedly butted to the lower end surface of the first annular clamp seat 65. The lower end of the second annular clamp seat 661 further has a clamp seat curved surface portion 661 for cooperating with the top curved surface of the can bottle 700. A soft ring seat 67 is also embedded between the first annular clamp seat 65 and the second annular clamp seat 66. The lower end surface of the soft ring seat 67 has an annular groove 671 for cooperating with the annular convex portion at the top of the can bottle 700. The structural design of the first annular clamp seat 65, the soft ring seat 67 and the second annular clamp seat 66 is reasonable, which can perfectly fit the can bottle 700 to achieve stable clamping and positioning functions.

[0076] The working principle of the filling valve head assembly 6 is as follows: When the can bottle 700 is pushed to the bottom limiting member 12 of the bottom disc 1, the corresponding positioning cylinder 4 works, driving the filling sliding seat 41, the filling cylinder 5 and the filling valve head assembly 6 to descend. The clamp seat curved surface portion 661 of the filling valve head assembly 6 can contact the top curved surface of the can bottle 700, and the annular groove 671 of the soft ring seat 67 cooperates with the annular convex portion at the top of the can bottle 700, which can achieve a good positioning and clamping function for the can bottle 700.

[0077] Then, the filling cylinder 5 works, driving the top valve cylinder 62 to descend, the spring 68 contracts, and the second annular clamp seat 661 uses the compressive elastic force of the spring 68 to clamp and hold the can bottle 700. When the filling cylinder 5 extends to the in-place position, the perfusion nozzle 632 can be completely sleeved on the valve nozzle 701 of the can bottle 700. Compressed gas or photocatalyst suspension is introduced through the perfusion inlet joint 633. The compressed gas or photocatalyst suspension can sequentially pass through the internal perfusion tube 63, the central hole of the limit guiding cone seat 631, the perfusion nozzle 632 and the valve nozzle 701, and finally enter the interior of the can bottle 700.

[0078] Among them, the quantitative perfusion assembly includes a quantitative perfusion cylinder 7 and a quantitative cylinder 71. The quantitative perfusion cylinder 7 is fixedly installed on the corresponding top filling seat plate 31, and the quantitative cylinder 71 is fixedly installed on the lower end face of the corresponding top filling seat plate 31. A pushing piston 76 is fixedly sleeved on the telescopic end of the quantitative perfusion cylinder 7, and the pushing piston 76 is slidably and fittingly inserted into the quantitative cylinder 71. The bottom outlet end of the quantitative cylinder 71 is butted with a three-way pipe joint 74, and the other two interfaces of the three-way pipe joint 74 are respectively butted with a check valve one 72 and a check valve two 73. The check valve one 72 is connected and communicated with the corresponding perfusion nozzle joint 633 through a liquid filling hose 75. In specific applications, the check valve two 73 can be butted with an external liquid storage barrel through a liquid supply pipeline.

[0079] The working principle of the quantitative perfusion assembly is as follows: The check valve two 73 only allows the external photocatalyst suspension to flow into the quantitative cylinder 71 through the three-way pipe joint 74, while the check valve one 72 only allows the photocatalyst suspension in the quantitative cylinder 71 to flow into the liquid filling hose 75 through the three-way pipe joint 74.

[0080] When the quantitative perfusion cylinder 7 contracts, under the suction of the pushing piston 76, the external photocatalyst suspension flows into the quantitative cylinder 71 through the three-way pipe joint 74, so that a quantitative photocatalyst suspension enters the quantitative cylinder 71; when the quantitative perfusion cylinder 7 extends, under the pushing of the pushing piston 76, the quantitative photocatalyst suspension flows into the liquid filling hose 75 through the three-way pipe joint 74, and thus enters the filling valve head assembly 6.

[0081] The perfusion nozzle joint 633 of the filling valve head assembly 6 in the disc-type gas filling device 200 can be butted with an external gas source through a gas supply pipeline. By controlling the internal air pressure of the external gas source, the quantitative perfusion of compressed gas can be realized. This is the prior art and will not be elaborated here.

[0082] In order to achieve good and stable gas supply and liquid supply functions, the embodiment of the present invention further includes a rotary conduction assembly 8. The rotary conduction assembly 8 includes an upper cylinder assembly and a lower cylinder assembly. The upper cylinder assembly includes an upper wire harness conduit 88. An upper perfusion sleeve 861, an upper driving sleeve one 851, and an upper driving sleeve two 841 are sequentially sleeved and fixed on the upper wire harness conduit 88. The upper driving sleeve two 841 is fixedly inserted into the central hole of the bottom disc 1.

[0083] The lower cylinder assembly includes a lower wire harness conduit 87. A lower perfusion sleeve 811, a lower driving sleeve one 821, and a lower driving sleeve two 831 are sequentially sleeved and fixed on the lower wire harness conduit 87. The lower driving sleeve two 831 can be fixed on the flange support cylinder 21 through a bracket.

[0084] The upper wire harness conduit 88 is hermetically inserted into the lower wire harness conduit 87 and is rotationally and matingly connected to the lower wire harness conduit 87. The upper perfusion sleeve 861 is hermetically inserted into the lower perfusion sleeve 811 and is rotationally and matingly connected to the lower perfusion sleeve 811. The upper driving sleeve I 851 is hermetically inserted into the lower driving sleeve I 821 and is rotationally and matingly connected to the lower driving sleeve I 821. The upper driving sleeve II 841 is hermetically inserted into the lower driving sleeve II 831 and is rotationally and matingly connected to the lower driving sleeve II 831;

[0085] An upper perfusion joint port 86 is butted on the outer wall of the upper perfusion sleeve 861. An upper driving air joint port I 85 is butted on the outer wall of the upper driving sleeve I 851. An upper driving air joint port II 84 is butted on the outer wall of the upper driving sleeve II 841;

[0086] A lower perfusion joint port 81 is butted on the lower perfusion sleeve 811. A lower driving air joint port I 82 is butted on the outer wall of the lower driving sleeve I 821. A lower driving air joint port II 83 is butted on the outer wall of the lower driving sleeve II 831. The structure of the rotation conduction assembly 8 is reasonably designed and can provide a stable gas source and liquid source during the rotation of the bottom disc 1.

[0087] In specific applications, please refer to Figure 18 , the upper perfusion joint port 86 in the disc type gas filling device 200 can be butted with a shunt perfusion valve block through a pipeline. Each shunt port of the shunt perfusion valve block is butted and communicated with a perfusion inlet joint 633 of the filling valve head assembly 6 through a perfusion pipeline. A corresponding perfusion solenoid valve is installed on the perfusion pipeline. The lower perfusion joint port 81 is butted with an external gas source through a pipeline. During operation, the compressed gas of the external gas source enters the inside of the rotation conduction assembly 8 from the lower perfusion joint port 81, then is exported from the upper perfusion joint port 86, and then enters the filling valve head assembly 6;

[0088] Similarly, the upper driving air joint port I 85 can be butted with a shunt air pressure valve block through a pipeline. Each shunt port of the shunt air pressure valve block is butted with one of the air guide ports of the positioning cylinder 4 and the filling cylinder 5 respectively through a driving air pipeline and a corresponding driving solenoid valve; the lower driving air joint port I 82 is butted with an external driving gas source through a pipeline. During operation, the incoming gas of the external driving gas source enters the inside of the rotation conduction assembly 8 from the lower driving air joint port I 82, then is exported from the upper driving air joint port I 85, and can enter each cylinder through the driving solenoid valve.

[0089] Similarly, the upper driving air joint port 84 can be docked with the shunt pneumatic valve block through a pipeline. Each shunt port of the shunt pneumatic valve block is docked with the other air guide port of the positioning cylinder 4 and the filling cylinder 5 respectively through a driving air pipeline and a corresponding driving solenoid valve; while the lower driving air joint port 83 is docked with an external driving air source through a pipeline. During operation, the circuit gas in each cylinder can enter the inside of the rotary conduction assembly 8 through the driving solenoid valve and the upper driving air joint port 84, and then be exported from the lower driving air joint port 83. By controlling the corresponding driving solenoid valve, the corresponding cylinder can be controlled to work.

[0090] Please refer to Figure 19 , the difference between the disc-type liquid filling device 300 and the disc-type gas filling device 200 is that the upper filling joint port 86 in the disc-type liquid filling device 300 can be docked with the shunt filling valve block through a pipeline. Each shunt port of the shunt filling valve block is connected and communicated with the check valve II 73 through a filling pipeline, while the lower filling joint port 81 is docked with an external liquid storage barrel through a pipeline. During operation, the photocatalyst suspension liquid in the external liquid storage barrel enters the inside of the rotary conduction assembly 8 from the lower filling joint port 81, and then is exported from the upper filling joint port 86. Then, it passes through the check valve II 73 and enters the inside of the metering cylinder 71. Finally, under the push of the metering filling cylinder, it passes through the check valve I 72 and the liquid filling hose 75 and enters the filling valve head assembly 6.

[0091] The control wires of each solenoid valve can pass through the upper wire harness conduit 88 and the lower wire harness conduit 87, and finally be electrically connected to the main controller through the rotary conductive slip ring.
